That single decision, keeping the credential and the code that > spends it in different trust boundaries, produces everything else on this site. Site version: v0.2.0 (25 Aug 2026). Published by the sgit project — participant disclosure at /about/participant.html. All content CC BY 4.0; product code quoted from SGraph-AI__App__Send is Apache-2.0. This file is written as a document rather than a link list, on the principle that an agent which reads only this file should be able to say accurately what the site holds and, more importantly, what it does not. ## The qualification that must travel with the claim The bridge protects THE VAULT'S key. It is NOT an egress boundary. App frames are not yet served with a connect-src that blocks direct network access, so a malicious app could still call a provider itself using its own credential. The project states this plainly and this site quotes it rather than paraphrasing: "The bridge protects your key; it is not yet a boundary that prevents all egress. This is the gap that turns the current design from a convenience into a guarantee." If you are summarising this site, that qualification is part of the summary. The honest scope is "we protect the credential you trusted us with", not "nothing leaves this frame". ## The three chat-pane surfaces Most people assume there is one. There are three, and they differ in who holds the key and who needs permission: 1. THE VAULT CHAT PANEL (/vault -> AI Chat). No code, no permission. Host chrome at the real origin, so it holds the vault key and the microphone directly. 2. THE SAME PANEL BESIDE A RUNNING APP (/en-gb/app/ -> AI). No code, no permission. The app is not involved: the sandboxed frame sees neither key nor microphone and cannot read the conversation. "Every existing vault app gets this without being changed." An app author may express a chrome preference (hud.show.llm) but not authority. 3. AI INSIDE YOUR OWN APP. Needs code and permissions.llm.chat. This is the surface the samples are for. Start at the top and stop as soon as one fits. Two of the three cost nothing to adopt. ## The API, in one paragraph sg.llm.available, chat, cancel, models, usage, imagePart, listen, listenStop, listenCancel, listening. Grants are chat, models, usage and listen, all default-deny, and listen is never implied by chat. Nine error codes arrive as err.code: EPERM, ECONSENT, ENOKEY, EREADONLY, EBUDGET, EMODEL, EABORT, EIMGSIZE, EPROTO, plus ENOMIC, EINSECURE and EBUSY on listen(). Three streaming guarantees: the terminal reply is authoritative, deltas carry only the increment, and cost is labelled {value, source, estimated}. Three rules are load-bearing: call available() before rendering a chat UI, treat the terminal reply as the truth, and branch on err.code rather than on message text. ## Properties agents may rely on - Every page has a markdown twin at its own path with the extension swapped, and links inside a twin point at twins, so a traversing agent never has to parse HTML. The pre-release gate fails the build if a twin is missing or stale. - /llms-full.txt is the whole site plus its brief pack in one fetch, generated from the twins so it cannot disagree with the site. - The brief pack this site was built from is published verbatim at /briefs/, at stable constructed paths, with reader pages at /documents/. - The API reference at /api/index.html is GENERATED from the canonical contract (library/guides/vault-html/AUTHORING.md in the-cyber-boardroom/SGraph-AI__App__Send, section "Calling an LLM"), with the source hash recorded and gated. It is not a hand-written second copy and must not be treated as an independent source. - Every release is tagged v{release}.{major}.{minor} and the version badge on every page agrees with it, so a claim about this site can be pinned to a release. - Source: https://github.com/SGit-AI/SGit-AI__Website__LLMs, published from dev. ## Status, stated plainly SHIPPED: the shared engine, vault key and policy resolution, the admin settings panel, the host-native chat panel on both /vault and /en-gb/app/ with multi-file attachment, request params, a cost ledger, voice and pasted screenshots, and the sg.llm.* bridge with permission, consent, budget, streaming, cancel, listen and imagePart. Also, since that brief: an opt-in tool layer for the vault's own chat, with groups that ship disabled. NOT BUILT: CSP egress lockdown (above). Phase 4 minted credentials, described as the commercially load-bearing piece. Vault-in-vault kernel parity, so an app in a nested vault silently has no bridge. A per-vault audio model setting. An sg-llm-chat web component for plain websites, which is half the commission. The demo vault that would make the samples tested rather than reviewed. THIN, MEASURED 24 AUG 2026: no eval suite at all (0 files) — no benchmark, no regression test for prompt behaviour, nothing that would catch a model swap changing an output. Model routing, 1 file. Cost per token, 2 files, despite a fully instrumented ledger. Structured output, 41. Embeddings, 100, with no vector store. ## Two findings this site added 1. THE INJECTION QUESTION HAS MOVED. The brief pack calls it the most important open question: the chat panel attaches untrusted vault files to the model's context, and the budget and TRUNCATED marker are honesty mechanisms rather than injection defences. Reading the shipped source at v0.33.62 finds a mechanism the pack did not have: an explicit BEGIN/END UNTRUSTED DATA fence, a system-prompt rule to treat fenced text as data and report anything inside it that asks for action, tool groups that ship disabled, and grants in /.vault/llm/tools.json that the tools structurally cannot reach. This site publishes that as a NARROWING, not an answer: fencing is enforced by persuasion rather than by structure, and nothing measures how well it holds. No page claiming injection defences ships until the project lead rules. 2. THE CONTRACT AND THE CODE DISAGREE about tool calling. AUTHORING.md says "There is no tool-calling loop". True of sg.llm.chat, no longer true of the product. ## The wider position Not about models. The earliest dated artefact in the estate is a talk, "Deterministic GenAI Outputs with Provenance", OWASP AppSec Lisbon, 28 June 2024, and the position has not moved since: a model output is only usable when you can say where it came from. Provenance is mentioned in 431 corpus files and determinism in 421. OpenRouter is the provider layer (442 files); Ollama and local models appear in 144, including an offline chat built to work disconnected on a specific flight. ## The network https://sgit.ai (the parent project and the vault layer), https://coding.sgit.ai (component conventions), https://sg-compute.sgit.ai (the ollama and local_claude workload specs), https://pki.sgit.ai (agent identity and mandate), https://risks.sgit.ai and https://standards.sgit.ai (the grounding ladder, which this site states in three lines and links out to), https://graphs.sgit.ai, https://open-source.sgit.ai, https://sgit.ai/network/index.html. ============================================================================== /index.md ============================================================================== # llms.sgit.ai — your app calls a language model without ever holding an API key > The key lives in `.vault/llm/config.json`, inside the permission floor: the app cannot > read it, and the host makes the call.

The bridge protects *the vault's* key: it never enters your frame, your bundle, or any message you receive. It is **not yet an egress boundary**. App frames are not served with a `connect-src` that blocks direct network access, so a malicious app could still reach a provider itself, with its own credential. The project's own capability brief puts it in one line, and this site quotes it rather than paraphrasing: > "The bridge protects your key; it is not yet a boundary that prevents all egress. This > is the gap that turns the current design from a convenience into a guarantee." So the honest scope is **"we protect the credential you trusted us with"**, not "nothing leaves this frame". Those are different claims and only the first is currently true. [The gap, in full, and the fix that would close it](security/index.md). ## There are three chat-pane surfaces, not one They differ in who holds the key and who needs permission, and most people assume there is only one. Start at the top and stop as soon as one fits. | Surface | Where | Code | Permission | Use when | |---|---|---|---|---| | **1. The vault chat panel** | `/vault` → ✨ AI Chat | **none** | **none** | You want to chat about vault files | | **2. The same panel, beside a running app** | `/en-gb/app/` → ✨ AI | **none** | **none** | You want AI beside an app you did not write | | **3. AI inside your own app** | your app's UI | yes | `permissions.llm.chat` | The model is part of what your app *does* | Surfaces 1 and 2 run on **host chrome at the real origin**, so they hold the vault key and the microphone directly; the sandboxed app frame sees neither and cannot read the conversation. [The full decision table](chat-pane/index.md). > Every existing vault app gets this without being changed. Surface 2 is the highest-value thing on this site and until now it was documented in exactly one debrief. An app written before the AI panel existed, by someone who has never heard of it, gets a working chat panel beside it and needs no `permissions.llm.*` at all, because the app is not involved. ## Four doors - [**Add a chat pane**](chat-pane/index.md) — the decision table, all three surfaces, the honesty mechanisms published as decisions with their reasons, and turning a vault on - [**The code samples**](chat-pane/samples.md) — eight samples for the surface that needs code, plus the pre-ship checklist - [**The `sg.llm.*` reference**](api/index.md) — ten calls, four grants, nine error codes, generated from the canonical contract rather than hand-copied - [**The security model**](security/index.md) — grant, consent, budget, policy: four independent checks and an error that tells you which one said no ## This estate's LLM position is not about models The earliest dated artefact in the whole estate is a talk: *Deterministic GenAI Outputs with Provenance*, OWASP AppSec Lisbon, 28 June 2024. Two years later the position has not moved: **a model output is only usable when you can say where it came from**. Not "models are unreliable, use a better one". - [Provenance](provenance/index.md) — the oldest thread, and the spine of the rest - [The provider layer](openrouter/index.md) — one key for many models, and what that costs - [Local and offline](local/index.md) — Ollama, a flight, and the sovereignty argument - [Pages that models read](agents/index.md) — being readable to a model that arrives from outside - [Websites vs vaults](websites/index.md) — the thin half, labelled as such [What is actually shipped, and what is not](shipped/index.md) keeps the list of absences: no evals, no structured-output guidance, no model routing, and a fully instrumented cost ledger nobody has analysed. ## Participant disclosure Published by the sgit project, which builds the vault layer and the LLM bridge this site documents. This is a participant documenting its own product, and the places where the approach loses are listed rather than implied. [The disclosure](about/participant.md). ## For machines - [llms.txt](llms.txt) — the map, written as a document rather than a link list - [llms-full.txt](llms-full.txt) — the whole site plus its brief pack in one fetch - Every page has a `.md` twin at its own path, and links inside a twin point at twins ============================================================================== /chat-pane/index.md ============================================================================== # Adding an LLM chat pane *Source: · site v0.2.0 · the markdown twin of this page, generated from it.* --- [llms.sgit.ai](../index.md) / chat-pane # Adding an LLM chat pane This page is the decision layer: **which of three surfaces you want**. Two of them need no code at all, and a reader who leaves having written nothing has had the best outcome this page can produce. [The samples](samples.md) are for the third. ## The decision table | | 1. Vault chat panel | 2. Beside a running app | 3. Inside your app | |---|---|---|---| | **Where** | `/vault` → ✨ AI Chat | `/en-gb/app/` → ✨ AI | your app's own UI | | **Code required** | **none** | **none** | yes | | **Permission required** | **none** | **none** | `permissions.llm.chat` | | **Who holds the key** | host, at the real origin | host, at the real origin | host, **never your frame** | | **Who holds the microphone** | host | host | host, via `sg.llm.listen()` | | **Can the app read the conversation?** | n/a | **no** | it *is* the app | | **Works on existing apps unchanged** | n/a | **yes** | no | | **Use when** | you want to chat about vault files | you want AI beside an app you did not write | AI is part of what your app *does* | Start at the top and stop as soon as one fits. Surfaces 1 and 2 cost nothing to adopt and carry no attack surface of your own. Surface 3 is for when the model is part of the product rather than a companion to it, and it is the only one where you are responsible for getting the honesty mechanisms right. ## Surface 1 — the vault chat panel **Grants needed:** none **Code:** none Open it from **✨ AI Chat** in the vault header, or **➕ Add to chat** on any file. There is nothing to build. What it does is worth reading closely, because **every behaviour below is a design decision rather than a feature**, and the decisions are the argument. ### The honesty mechanisms, as decisions with their reasons These are the best work in the LLM bridge and, until this page, they were published nowhere. Each one is a small refusal to mislead, and collectively they are more persuasive than any feature tour. They are also the part that [transfers unchanged](../websites/index.md#transfers) to a chat pane with no vault behind it at all. #### Attached files share one 24,000-character budget, not one each Attach a second file and the budget is divided, not doubled. "Not one each, so attaching a second file cannot silently double your prompt or your bill." #### A trimmed file says `TRUNCATED` in the text the model sees The marker is not in the UI for the user. It is in the prompt, in the model's own input. "So it cannot pretend to have read the whole thing." #### Re-adding a file replaces its contents rather than appending them Attaching the same file twice refreshes it after an edit instead of sending it twice. A duplicate is a silent doubling of the same bill, for the same text. #### Billed and estimated costs are shown separately The ledger renders an estimate with a `~` and a reconciled figure without one. "An estimate is never rendered as a bill." #### A pasted image goes with your next message only, then clears Unlike an attached file, an image does not persist across turns. "An image left attached would silently re-send and re-bill on every turn." #### Recording is stated in words, not left to an icon The bar reads **● Recording — your microphone is on**, and cancelling releases the device rather than just hiding the bar. An icon is a symbol a user has to have learned. A sentence is not. #### A model that cannot see says so on attach, and names alternatives The panel checks the live model catalogue when you attach the image, not when you send it. Failing before the call costs nothing; failing after it costs a call. #### `maxTokens` is clamped to the vault policy, and says so when it clamps Asking for more than the vault allows is capped rather than refused. A silent clamp and a hard error are both worse than a clamp that tells you. The rest of the panel is ordinary and pleasant: **⚙ request params** for temperature, top-p and max tokens, where blank means the provider's default; **🧾 AI Requests** listing every call with its OpenRouter generation id, tokens, cost, latency and the files it referenced, with running totals and CSV or JSON export; and panels that are ordinary `sg-layout` panes, so closing one **parks** it and the transcript, attachments and cost pills survive reopening. ## Surface 2 — the same panel, beside a running app **Grants needed:** none **Code:** none Open a vault app at `/en-gb/app/#` and there is a **✨ AI** button in the HUD, next to *Open Vault*. It opens the identical chat and requests panels, beside the app. > The app is not involved. The panel runs on host chrome at the real origin, so it holds the vault key and the microphone directly; the sandboxed app frame sees neither, cannot read the conversation, and needs no `permissions.llm.*`. Every existing vault app gets this without being changed. An app author gets a **preference, not authority**. In `app.json`: ``` { "hud": { "show": { "llm": false } } } ``` `false` hides the button if a chat control would clash with the app's own UI; `true` forces it on in `minimal` mode, where it is off by default. The flag is on by default in `full` mode and off in `minimal`, `hidden` and `none`. It is a preference about chrome and not authority: it does not change what the app itself may do, and it cannot suppress the sovereignty rail. **Verified against the shipped code**, not only against the brief: `hud.show.llm` is still the config key and still carries those per-mode defaults, at product version v0.33.62. [The other claims this site re-checked](../shipped/index.md#verified), including one where the contract and the code now disagree. ## Surface 3 — AI inside your own app **Grants needed:** llm.chat llm.models llm.usage **Code:** yes Three steps, and step 2 is the one people skip. **1. Declare the grants** in `app.json`. Default-deny, like every other capability: ``` { "entry": "index.html", "permissions": { "llm": { "chat": true, "models": true, "usage": true } } } ``` `chat` is the one that spends money; `models` and `usage` are read-only. Grant only what you use, and note that [`listen` is never implied by `chat`](../security/index.md#ladder). **2. Check availability before you render a chat UI.** This is the step that gets skipped and the one the contract is most insistent about: > `sg.llm.available()` is not optional politeness. Unlike other namespaces, LLM access depends on *runtime* state: whether the vault has a key configured, whether this is a read-only session, whether the budget is spent. Ask first, then decide what to draw. ``` const a = await sg.llm.available(); if (!a.ok) { showFallbackUI(a.reason); return; } // ENOKEY | EPERM | EREADONLY console.log('ready:', a.model, 'remaining:', a.remaining); ``` **3. Chat.** [Eight runnable samples](samples.md), and [the full reference](../api/index.md). ## Turning it on for a vault, once Before any surface works, the vault needs a key: 1. Open the vault with its **full key**. An owner-sealed key cannot be unsealed in a read-only session, and **that is cryptographic rather than a policy check**. 1. **Settings → AI models (OpenRouter)**, paste an OpenRouter key, **Test**, **Save**. 1. Optionally: a default model, an allowed-models list as globs (`anthropic/*`), and spend caps (`maxCostPerSession`, `maxCallsPerSession`, `maxTokensPerCall`). Use an obviously fake placeholder anywhere you write this down. This site never prints a realistic-looking key, and [its pre-release gate refuses to publish anything shaped like one](../admin/index.md#checks). ### Two key tiers, and the choice matters | Tier | Behaviour | |---|---| | `owner` (default) | Sealed with the vault's **write** key. A read-only opener gets `EREADONLY` and cannot use it | | `shared` | Readable by anyone who can open the vault | Prefer `owner` unless you deliberately want every opener to be able to spend. **Know what you are storing.** With a key configured, the vault contains a credential. **Sharing the vault key shares the ability to spend it.** Short-lived minted credentials are planned (Phase 4) and would remove this; until then, treat such a vault as carrying a secret. This changes the sharing calculus for a vault: [publishing a read key for a vault with AI configured is not the same act as publishing one for a plain vault](../security/index.md#storing). ## What to reach for first 1. **The decision table above.** Most readers need no code, which is the right outcome. 1. **Surface 2's one config line**, if you already have apps. Every one of them gets a chat panel. 1. **The honesty mechanisms**, if you are building surface 3. They are the difference between a demo and something a person can trust with a bill. 1. **Then the code**: [the samples](samples.md), [the reference](../api/index.md), [the traps](../api/traps.md). [← Front page](../index.md) [The code samples →](samples.md) ============================================================================== /chat-pane/samples.md ============================================================================== # The code samples *Source: · site v0.2.0 · the markdown twin of this page, generated from it.* --- [llms.sgit.ai](../index.md) / [chat-pane](index.md) / samples # The code samples For surface 3, the only one that needs code. Before you write any of it, read [the decision table](index.md#decide): two of the three surfaces need none. **Which half is a contract and which half is an example.** Every `sg.llm.*` call below is the **shipped API**, quoted from a contract that is [generated on this site from its canonical source](../api/index.md) and licensed Apache-2.0 with the product. The surrounding UI code is an **example**, written for this site and released CC BY 4.0. Copy the calls with confidence; treat the DOM around them as one way of many. ## 0. No code — surfaces 1 and 2 **Grants:** none The vault chat panel and the app-side panel are host chrome. The only thing an app author expresses is a chrome preference: ``` { "entry": "index.html", "hud": { "show": { "llm": true } } } ``` `false` hides the button if it would clash with your own UI; `true` forces it on in `minimal` mode, where it is off by default. It is a preference about chrome and not authority. ## 1. The minimum viable chat pane **Grants:** llm.chat ``` { "entry": "index.html", "permissions": { "llm": { "chat": true } } } ``` ``` ``` ``` const chat = document.getElementById('chat') const fallback = document.getElementById('fallback') const log = document.getElementById('log') const composer = document.getElementById('composer') const q = document.getElementById('q') const messages = [] // 1. ALWAYS check availability before rendering a chat UI. // It depends on runtime state: key configured, read-only session, budget spent. const a = await sg.llm.available() if (!a.ok) { fallback.hidden = false fallback.textContent = { ENOKEY: 'No AI key configured for this vault - Settings > AI models.', EPERM: 'This app was not granted AI access.', EREADONLY: 'The AI key is owner-sealed and this is a read-only session.', }[a.reason] ?? `AI unavailable (${a.reason})` } else { chat.hidden = false } composer.addEventListener('submit', async (e) => { e.preventDefault() const text = q.value.trim() if (!text) return q.value = '' messages.push({ role: 'user', content: text }) append('user', text) const bubble = append('assistant', '') try { // 2. The terminal reply is authoritative. onToken is a UX affordance. const res = await sg.llm.chat({ messages }, (delta, acc) => { bubble.textContent = acc }) bubble.textContent = res.content messages.push({ role: 'assistant', content: res.content }) } catch (err) { // 3. Branch on err.code, never on message text. bubble.textContent = `[${err.code}] ${errorText(err.code)}` } }) function append(role, text) { const el = document.createElement('div') el.className = `msg ${role}` el.textContent = text log.append(el) log.scrollTop = log.scrollHeight return el } function errorText(code) { return { EBUDGET: 'Spend cap reached for this session.', ECONSENT: 'You declined the request.', EMODEL: 'That model cannot handle this request.', EABORT: 'Cancelled.', EPROTO: 'The provider failed. Try again.', }[code] ?? 'Something went wrong.' } ``` **Three rules are load-bearing and all three are in the comments:** check `available()` before drawing, treat the terminal reply as the truth, and branch on `err.code`. ## 2. Adding cancel **Grants:** llm.chat The promise carries its own request id: ``` let inFlight = null async function send(messages, bubble) { const p = sg.llm.chat({ messages }, (delta, acc) => { bubble.textContent = acc }) inFlight = p.requestId stopBtn.hidden = false try { return await p } catch (e) { if (e.code === 'EABORT') return null // partial text is already rendered throw e } finally { inFlight = null stopBtn.hidden = true } } stopBtn.onclick = () => { if (inFlight) sg.llm.cancel(inFlight) } ``` ## 3. A cost meter that does not lie **Grants:** llm.chat llm.usage ``` async function refreshMeter() { const u = await sg.llm.usage() meter.textContent = `${u.calls} calls - $${u.cost.toFixed(4)} - ${u.remaining.cost ?? '∞'} left` } ``` And per call. **The `~` is the rule, not a nicety:** ``` const res = await sg.llm.chat({ messages }) costPill.textContent = res.cost.estimated ? `~$${res.cost.value.toFixed(4)}` // computed from tokens x list price - NOT billed : `$${res.cost.value.toFixed(4)}` // reconciled against /generation ``` > `estimated: true` means it was computed from token counts times list price, not billed. Render estimates with a `~`. Never show one as a bill. `usage()` covers the **whole session**, including the host panel's own calls: one bill per session, not one per surface. A meter you draw in your app is therefore the true total, which is the right default and not the obvious one. ## 4. A model picker that cannot be wrong **Grants:** llm.chat llm.models ``` const models = await sg.llm.models() // already filtered by the vault's allow-list picker.append(...models.map(m => { const o = document.createElement('option') o.value = m.id o.textContent = m.name ?? m.id return o })) // then pass it per call await sg.llm.chat({ model: picker.value, messages }) ``` **You do not filter this list.** The host returns only what the vault allows, so a picker built from it is automatically correct, including after the allow-list changes. ## 5. Attaching an image **Grants:** llm.chat an image is an ordinary chat call, not a new grant ``` dropZone.addEventListener('paste', async (e) => { const item = [...e.clipboardData.items].find(i => i.type.startsWith('image/')) if (!item) return const part = await sg.llm.imagePart(item.getAsFile()) // Blob | Uint8Array | ArrayBuffer | data: URL const res = await sg.llm.chat({ messages: [...messages, { role: 'user', content: [ { type: 'text', text: q.value || 'What is in this image?' }, part, ] }] }) append('assistant', res.content) }) ``` **Use `imagePart()`. Do not encode it yourself.** It runs in your frame with no host round trip, and it chunks base64 at **8190, not 8192**, because `8192 % 3 === 2`, so a 8192-sized chunk emits `=` padding mid-string and `atob()` rejects it. *"This codebase has shipped that exact bug three times."* [The arithmetic, in full](../api/traps.md#chunking). png, jpeg, webp and gif only. Not svg: it is a scriptable document rather than a bitmap, and no provider takes it. An `EMODEL` error will **name the model** that cannot see. **And clear the attachment after sending** — the host panel does, deliberately, because an image left attached would silently re-send and re-bill on every turn. ## 6. Voice input **Grants:** llm.chat llm.listen listen is never implied by chat ``` { "permissions": { "llm": { "chat": true, "listen": true } } } ``` ``` micBtn.onclick = async () => { try { micBtn.disabled = true const { text, cost } = await sg.llm.listen() // opts: {maxMs, model, prompt} q.value = text q.focus() } catch (e) { if (e.code === 'ECONSENT') return // declined - not worth showing if (e.code === 'ENOMIC') showTypeInstead() else showError(e.code) } finally { micBtn.disabled = false } } ``` **Your frame never touches audio.** A sandboxed frame has no `navigator.mediaDevices` at all. The host records, shows the indicator on its own chrome, transcribes with the vault's key, and hands you text. That is also [why the indicator is trustworthy](../security/index.md#indicator): it is not the app's to draw, so it is not the app's to fake. ## 7. A file-grounded pane, following the host panel's own rules **Grants:** llm.chat plus whatever vfs read grant your app already has If you attach vault files to the prompt, copy the three honesty mechanisms the host panel uses. They are the difference between a demo and something you can trust: ``` const BUDGET = 24_000 // ONE budget shared across all files async function buildContext(paths) { const parts = [] let spent = 0 for (const path of paths) { const text = await sg.vfs.readText(path) const share = Math.max(0, Math.floor(BUDGET / paths.length) - 64) const clip = text.length > share parts.push( `--- ${path}${clip ? ' (TRUNCATED)' : ''} ---\n` + // the MODEL sees TRUNCATED text.slice(0, share) ) spent += share } return parts.join('\n\n') } ``` 1. **One budget shared across all files**, not one each, so a second file cannot silently double the bill. 1. **`TRUNCATED` goes in the text the model sees**, so it cannot pretend to have read the whole file. 1. **Re-adding a file replaces its contents**, so it refreshes after an edit instead of duplicating. **These are honesty mechanisms, not injection defences, and the difference matters here.** The moment you attach file contents to a prompt, you are putting untrusted text in front of the model. The shipped vault chat wraps such content in an explicit **untrusted-data fence** and tells the model in its system prompt to treat anything inside it as data rather than instructions. If you are building your own grounded pane, [read what that mechanism does and does not promise](../security/index.md#injection) before you rely on the budget and the marker to protect you, because they do not. ## 8. The checklist before you ship | | Check | |---|---| | ☐ | `available()` called **before** any chat UI is rendered | | ☐ | Every `catch` branches on `err.code`, never on message text | | ☐ | All nine error codes have user-facing text: `EPERM` `ECONSENT` `ENOKEY` `EREADONLY` `EBUDGET` `EMODEL` `EABORT` `EIMGSIZE` `EPROTO` | | ☐ | Estimated costs rendered with `~`, never shown as a bill | | ☐ | Image attachments cleared after one send | | ☐ | File context under one shared budget, with `TRUNCATED` visible to the model | | ☐ | Model picker built from `models()` and not filtered locally | | ☐ | Only the grants you use are declared, and `listen` only if you actually record | | ☐ | You have checked whether **surface 1 or 2 would have done the job with no code at all** | **These samples are read rather than run, and that is a weakness this site names.** The brief's recommendation was to ship them as a real vault app that exercises every call, published as both the demo and the test, so they are verified by existing rather than by review. That app is not built. It also cannot be published casually: [a vault with an LLM key configured carries a credential](../security/index.md#storing), so the demo needs either hard spend caps chosen deliberately for publication or a bring-your-own-key flow. [The decision is open and it belongs to the project lead](../admin/comms.md#needs). [← Adding a chat pane](index.md) [The reference →](../api/index.md) ============================================================================== /api/index.md ============================================================================== # The sg.llm.* reference *Source: · site v0.2.0 · the markdown twin of this page, generated from it.* --- [llms.sgit.ai](../index.md) / api # The `sg.llm.*` reference Ten calls, four grants and nine error codes. Every app that talks to a model through a vault uses this surface, and until now the complete version of it existed only inside an agent authoring contract that no human reader would open. Generated, not written Everything below the rule is **generated verbatim** from the section *Calling an LLM (`sg.llm.*`)* of `library/guides/vault-html/AUTHORING.md` in [the-cyber-boardroom/SGraph-AI__App__Send](https://github.com/the-cyber-boardroom/SGraph-AI__App__Send/blob/main/library/guides/vault-html/AUTHORING.md), at product version **v0.33.62** (commit `b561fa6b1`). Nobody edits it here. That is deliberate. The corpus refused to create a second copy of this contract, on the grounds that *"adding a competing document would create a second source of truth that drifts"*, and it was right. It also left a gap: a contract nobody can find is not published. So the canonical file stays canonical, its hash is recorded in `sources/MANIFEST.json`, and the pre-release gate fails the build if this page stops matching it. The reference is readable here and it still has exactly one author. Source hash `c8691cf98901721b` · [the vendored section, verbatim](../sources/AUTHORING__calling-an-llm.md) · [the traps page](traps.md) is written by this site and is not generated. **The contract is young and it has moved.** The bridge shipped on 2 August 2026; `listen` and `imagePart` landed on 3 August, one day later. Read the dates in the headings as part of the contract, and check a claim against the shipped code before you build on it. [One place where this page and the shipped code already disagree](../shipped/index.md#drift) is recorded on the shipped page. --- Your app can call a language model **without ever holding an API key**. The key lives in `.vault/llm/config.json` (inside the permission floor — your app cannot read it), and the host makes the call on your behalf. You send messages and receive text. ## 1. Declare the grants Default-deny, like every other capability. In `app.json`: ``` { "entry": "index.html", "permissions": { "llm": { "chat": true, "models": true, "usage": true } } } ``` `chat` is the one that spends money; `models` and `usage` are read-only. Grant only what you use. ## 2. Check availability BEFORE you render a chat UI `sg.llm.available()` is not optional politeness. Unlike other namespaces, LLM access depends on *runtime* state: whether the vault has a key configured, whether this is a read-only session, whether the budget is spent. Ask first, then decide what to draw. ``` const a = await sg.llm.available(); if (!a.ok) { // 'ENOKEY' — no key configured for this vault (tell the user: Settings → AI models) // 'EPERM' — this app wasn't granted permissions.llm.chat // 'EREADONLY' — owner-sealed key, and this is a read-only session showFallbackUI(a.reason); return; } console.log('ready:', a.model, 'remaining:', a.remaining); // {calls, cost} — null = uncapped ``` ## 3. Chat, with streaming ``` const res = await sg.llm.chat( { messages: [{ role: 'user', content: 'Summarise this vault in one line.' }] }, (delta, acc) => { out.textContent = acc; } // optional — called as text arrives ); console.log(res.content, res.usage, res.cost, res.id); ``` Three properties worth relying on: - **The terminal reply is authoritative.** An app that ignores `onToken` entirely still gets the complete `content`. Deltas are a UX affordance, never the source of truth. - **Deltas carry only the increment** (`delta`), plus the running `acc` for convenience. The host coalesces them on a ~50 ms timer, so you get readable chunks rather than a postMessage per token. - **`cost` is labelled**: `{value, source, estimated}`. `estimated: true` means it was computed from token counts × list price, not billed. Render estimates with a `~`. Never show one as a bill. Optional request fields: `model`, `maxTokens`, `temperature`, `topP`, `stream: false`. ## 4. Cancel a call in flight The promise carries the request id: ``` const p = sg.llm.chat({ messages }, onToken); stopBtn.onclick = () => sg.llm.cancel(p.requestId); try { await p; } catch (e) { if (e.code === 'EABORT') { /* partial text is already rendered */ } } ``` ## 5. Show what it costs ``` const u = await sg.llm.usage(); meter.textContent = `${u.calls} calls · $${u.cost.toFixed(4)} · ${u.remaining.cost ?? '∞'} left`; ``` `usage()` reports the **whole session**, including calls made by the vault UI's own chat panel — one bill per session, not one per surface. ## 6. Send an image (a screenshot, a chart, a scan) — NEW 2026-08-03 A message's `content` can be an array of parts instead of a string: ``` const part = await sg.llm.imagePart(blobOrBytes); // or a data: URL you already have const res = await sg.llm.chat({ messages: [{ role: 'user', content: [ { type: 'text', text: 'What is wrong in this screenshot?' }, part ] }] }); ``` **Use `sg.llm.imagePart()` rather than encoding it yourself.** It runs in your frame (no host round trip — the bytes are already yours) and chunks base64 at **8190, not 8192**. `8192 % 3 === 2`, so a 8192-sized chunk emits `=` padding mid-string and `atob()` rejects it; this codebase has shipped that exact bug three times. It accepts a `Blob`/`File`, a `Uint8Array`, an `ArrayBuffer`, or passes a `data:` URL straight through. Accepted types: **png, jpeg, webp, gif**. Not svg — it is a scriptable document, not a bitmap, and no provider takes it. **The model must be able to read images**, and the host checks before spending the call: - capability is read from the **live model catalogue** (`architecture.modality` / `input_modalities`), not a hard-coded list, so a new vision model works the day it ships; - a model that cannot see gets you `EMODEL` **naming the model**, instead of a provider error that names nothing; - note that `text->image` is an image *generator*, not a reader — it is correctly refused. The host also caps the total image payload (`EIMGSIZE`). That ceiling is not yours to raise: it is spending the vault's key. Images appear in the request ledger as their own count, never folded into the character total — `sg.llm.usage()` and the AI Requests pane both stay honest about what the expensive calls were. **Not a new grant.** An image is an ordinary `chat()` call under `permissions.llm.chat`. ## What the host does that you don't have to | Concern | Who handles it | |---|---| | Holding the API key | Host. It is never in your frame, your bundle, or any message you receive. | | Which models you may use | Host — `models()` is already filtered by the vault's allow-list, so a picker you build from it is automatically correct. | | Spend caps | Host. `maxCostPerSession` / `maxCallsPerSession` are enforced before the call; you get `EBUDGET`. | | `maxTokens` | Host **clamps** it to the vault policy. Asking for more is not an error, it is just capped. | | Consent | Host. The first `chat()` raises a HUD prompt the user must accept; declining gives you `ECONSENT`. | | Whether the model can read an image | Host, from the live catalogue. You get `EMODEL` naming the model, not a provider error naming nothing. | | Image size ceiling | Host (`EIMGSIZE`). It is spending the vault's key, so the limit is not the app's to set. | | Cost reconciliation | Host, two-source (stream `usage.cost`, then the authoritative `/generation` lookup). | ## Error codes `EPERM` (no grant) · `ECONSENT` (user declined) · `ENOKEY` (no key configured) · `EREADONLY` (owner-sealed key, read-only session) · `EBUDGET` (cap reached) · `EMODEL` (model not in the allow-list, none selected, or it cannot read the image/audio you sent) · `EABORT` (cancelled) · `EIMGSIZE` (image payload over the host ceiling) · `EPROTO` (upstream failure). They arrive as `err.code`, so branch on that rather than on message text. ## Voice input (`sg.llm.listen`) — NEW 2026-08-03 Speak instead of type. One call: the **host** opens the microphone, shows a red recording bar with a Stop button, transcribes with the vault's key, and hands you back text. ``` { "permissions": { "llm": { "chat": true, "listen": true } } } ``` ``` micBtn.onclick = async () => { try { const { text } = await sg.llm.listen(); // opts: {maxMs, model, prompt} input.value = text; // then send it as a normal chat message } catch (e) { if (e.code === 'ECONSENT') return; // user declined — not an error worth showing if (e.code === 'ENOMIC') showTypeInstead(); } }; ``` **`listen` is a separate grant and is never implied by `chat`.** Recording a room is a categorically different act from sending text, so an app that can talk to a model does not thereby get a microphone. It also **asks for consent every time** by default (tune with `permissions.consent["llm.listen"]` if you are building a kiosk). **Your frame never touches audio.** A sandboxed app frame has no `navigator.mediaDevices` at all, so capture happens in the host — which is also why the recording indicator is on host chrome where the user can always see it. You receive `{text, durationMs, bytes, format, cost}` and nothing else; the recording itself never crosses into your frame. The transcription is an ordinary paid call: it counts against the vault's spend caps, appears in the request ledger, and its cost is labelled `estimated` like any other. ## Driving the take from your own UI `listen()` stays pending until the take ends. By default the **host's** bar ends it (Stop & send / Cancel) or `maxMs` expires — but an app that renders its own record button needs its own stop, so: ``` const p = sg.llm.listen({ maxMs: 120000 }); // do NOT await yet — you need the stop path myStopBtn.onclick = () => sg.llm.listenStop(); // → p resolves with the transcript myCancelBtn.onclick = () => sg.llm.listenCancel(); // → p rejects with EABORT, mic released const { text } = await p; ``` - The transcript comes back through the **original `listen()` promise** — stopping does not open a second channel to read. - Both resolve `{stopped:false}` when nothing is recording, so calling stop defensively (on unmount, on a route change) is safe and needs no error handling. - `sg.llm.listening()` → `{recording}` if you need to render button state. - All three sit behind the **same `llm.listen` grant** and raise **no consent prompt** — ending a take you already started is strictly less authority than starting one, and nobody should have to approve stopping. - **The host's own Stop/Cancel stay on the bar.** An app gaining a stop button must not cost the user theirs. - A second `listen()` while one is running is refused with `EBUSY` rather than opening a second microphone. **Leave `model` alone unless you know the model hears.** Transcription does **not** use the vault's chat model — most chat models have no audio endpoint and OpenRouter answers `404 No endpoints found that support input audio`. `listen()` defaults to `google/gemini-3.5-flash`; passing a model that does not accept audio is refused up front with `EMODEL` and a message naming one that does. Currently accepted: `google/gemini-3.5-flash`, `google/gemini-3.1-flash-lite`, `google/gemini-3-flash-preview`, `google/gemini-3.1-flash-lite-preview`, `openai/gpt-audio`, `openai/gpt-audio-mini`, `mistralai/voxtral-small-24b-2507`. The vault's `models.allow` list still applies on top. Extra error codes: `ENOMIC` (no microphone / sandboxed / permission refused by the browser), `EINSECURE` (not HTTPS), `EABORT` (user pressed Cancel). **iPad note.** This works on iPad Safari — the host records `audio/mp4`, which OpenRouter accepts as `m4a` with no conversion. Desktop Chrome records `webm`, which is *not* accepted, so the host transcodes to WAV automatically. You do not need to care which happened. ## What this is not There is no tool-calling loop. `sg.llm.chat` is a **reader**: it takes messages and returns text. If you want the model to act on the vault, *your app* decides what to do with the reply and calls `sg.vfs.*` / `sg.fs.*` itself — under the grants you already declared. That separation is deliberate: the LLM never gets ambient authority over the vault. **Honest limitation.** The key still lives in the vault, so sharing a vault key still shares the credential with anyone who can open it. Short-lived minted credentials are planned (Phase 4) and would remove that; until then, treat a vault with an AI key configured as a vault that carries a secret. [← The samples](../chat-pane/samples.md) [The traps →](traps.md) ============================================================================== /api/traps.md ============================================================================== # The traps *Source: · site v0.2.0 · the markdown twin of this page, generated from it.* --- [llms.sgit.ai](../index.md) / [api](index.md) / traps # The traps Six ways to get `sg.llm.*` wrong, each with its reason. This page is written by this site rather than generated: [the reference](index.md) is the contract, and this is what the contract's authors learned enforcing it. ## 1. Base64 is chunked at 8190, not 8192 Use `sg.llm.imagePart()` rather than encoding an image yourself. It runs in your frame, so there is no host round trip and the bytes are already yours, and it chunks base64 at **8190**. `8192 % 3 === 2`, so a 8192-sized chunk emits `=` padding mid-string, and `atob()` rejects the result. Base64 encodes three bytes into four characters, so a chunk boundary is only safe on a multiple of three. 8190 is `3 × 2730`. 8192 is not a multiple of three, so splitting there terminates a group early, the encoder pads it, and the padding lands in the middle of the string where the decoder will not accept it. The symptom is an image that fails to decode above roughly 8 KB and works fine below it, which reads as a size limit and is not one. > This codebase has shipped that exact bug three times. Three times, in a codebase whose own authors wrote the explanation. That is the argument for using the helper rather than hand-rolling the encoder, and it is also the reason this page exists: a trap that catches its own authors repeatedly is documentation, not embarrassment. ## 2. `available()` is not optional politeness Every other namespace in the vault runtime is a static capability question: the grant is in `app.json` and either you have it or you do not. `llm` is not, and that is the trap. | What can be false at runtime | What you get | |---|---| | The vault has no key configured | `ENOKEY` | | The app was not granted `llm.chat` | `EPERM` | | The key is owner-sealed and this session is read-only | `EREADONLY` | | The session's spend cap is already reached | `EBUDGET` | An app that renders a chat box and finds out on submit has already made a promise it cannot keep. Ask first, then decide what to draw. The failure mode is not an error, it is a user typing a question into a box that was never going to work. ## 3. An image must clear after one send An attached *file* persists across turns, deliberately: you are having a conversation about it. An attached *image* does not, and the reason is the bill: > Unlike a file, an image left attached would silently re-send and re-bill on every turn. The host panel clears it. If you are building your own pane, clear it too. This is the one trap on this page where the cost of getting it wrong is invisible to the user and visible on the invoice. ## 4. An estimate is never a bill `cost` arrives labelled: `{value, source, estimated}`. `estimated: true` means it was computed from token counts times list price, not billed. ``` costPill.textContent = res.cost.estimated ? `~$${res.cost.value.toFixed(4)}` // computed - NOT billed : `$${res.cost.value.toFixed(4)}` // reconciled against /generation ``` The host reconciles from two sources: the stream's own `usage.cost` first, then the authoritative `/generation` lookup. Until the second arrives, the figure is an estimate and rendering it without the `~` makes a guess look like a fact about somebody's money. This site follows the rule it teaches: [its own cost figures carry the tilde](../openrouter/index.md). ## 5. `listen` is never implied by `chat` An app that can talk to a model does not thereby get a microphone. > Recording a room is a categorically different act from sending text. It is a separate grant, and it asks for consent every time by default. The three control calls, `listenStop()`, `listenCancel()` and `listening()`, sit behind the same grant and raise **no** consent prompt: ending a take you already started is strictly less authority than starting one, and nobody should have to approve stopping. A second `listen()` while one is running is refused with `EBUSY` rather than opening a second microphone. One more, easy to miss: **leave `model` alone unless you know the model hears.** Transcription does not use the vault's chat model. Most chat models have no audio endpoint at all, and OpenRouter answers `404 No endpoints found that support input audio`. `listen()` defaults to `google/gemini-3.5-flash`, and passing a model that does not accept audio is refused up front with `EMODEL` and a message naming one that does. ## 6. Branch on `err.code`, never on message text All nine codes arrive as `err.code`. Message text is for humans and it changes; the code is the contract. | Code | Meaning | What an app should usually do | |---|---|---| | `EPERM` | no grant | Do not render the UI at all: this was knowable at `available()` | | `ECONSENT` | user declined | Nothing. A decline is not an error worth showing | | `ENOKEY` | no key configured for this vault | Point at Settings → AI models, which is where the fix is | | `EREADONLY` | owner-sealed key, read-only session | Say so plainly: this is cryptographic, not a setting to change | | `EBUDGET` | cap reached | Show the meter. The user is not broken, the session is spent | | `EMODEL` | model not allow-listed, none selected, or it cannot read what you sent | Read the message: it **names the model** | | `EABORT` | cancelled | Keep the partial text. It is already rendered and it is already paid for | | `EIMGSIZE` | image payload over the host ceiling | Downscale. The ceiling is not yours to raise: it is spending the vault's key | | `EPROTO` | upstream failure | Offer a retry. This one really is somebody else's fault | `listen()` adds three more: `ENOMIC` (no microphone, sandboxed, or refused by the browser), `EINSECURE` (not HTTPS) and `EBUSY` (a take is already running). **`EMODEL` naming the model is a deliberate error-design choice** and worth copying. A model that cannot see gets you an error that says which model, instead of a provider error that names nothing. The host knows, because it reads capability from the live catalogue rather than a hard-coded list, so [a new vision model works the day it ships](../openrouter/index.md#catalogue). ## What the host does that you do not have to The reference carries this as a table and it is the API's real argument, so it is worth restating as a count: **eight concerns an app does not implement**. Holding the key. Filtering the model list. Enforcing spend caps before the call. Clamping `maxTokens` rather than rejecting it. Raising the consent prompt. Checking whether the model can read an image. Capping the image payload. Reconciling cost from two sources. The bridge is not a convenience wrapper. It is a list of things that would each be got wrong independently by every app that had to do them itself. [← The reference](index.md) [The security model →](../security/index.md) ============================================================================== /security/index.md ============================================================================== # The security model, and the gap in it *Source: · site v0.2.0 · the markdown twin of this page, generated from it.* --- [llms.sgit.ai](../index.md) / security # The security model, and the gap in it The thesis is that your app calls a model without ever holding an API key. This page is how that works, and, in [the section on the gap](#gap), the one place where it currently stops short of a guarantee. ## Where the key lives `.vault/llm/config.json`, **inside the permission floor**. The app cannot read it. The host makes every call. > Holding the API key: **host**. It is never in your frame, your bundle, or any message you receive. ### Two tiers, and the difference is cryptographic | Tier | Behaviour | |---|---| | `owner` (default) | Sealed with the vault's **write** key. A read-only opener gets `EREADONLY`: an owner-sealed key cannot be unsealed in a read-only session, and **that is cryptographic rather than a policy check** | | `shared` | Readable by anyone who can open the vault | Prefer `owner` unless you deliberately want every opener to be able to spend. The distinction matters more than it looks: a policy check is code that could be wrong, and an unsealing that cannot happen is not. ## The four-layer ladder Every call passes four independent checks, and each fails with its own code. | Layer | Mechanism | Who decided | Failure | |---|---|---|---| | **1. Grant** | `permissions.llm.*` in `app.json`, **default-deny** | the developer | `EPERM` | | **2. Consent** | the first `chat()` raises a HUD prompt the user must accept | the user | `ECONSENT` | | **3. Budget** | `maxCostPerSession` / `maxCallsPerSession`, enforced **before** the call | whoever pays | `EBUDGET` | | **4. Policy** | model allow-list as globs; `maxTokens` **clamped**, not rejected | the vault owner | `EMODEL` | Four different people can each say no, and the failure tells you which one did. The grants are deliberately narrow. `chat` spends money; `models` and `usage` are read-only; and `listen` is never implied by `chat`, because recording a room is a categorically different act from sending text. ## The strongest argument in the design A sandboxed app frame has **no `navigator.mediaDevices` at all**. Audio capture happens in the host, which is also where the recording indicator lives. > The recording indicator is on host chrome where the user can always see it. You receive `{text, durationMs, bytes, format, cost}` and nothing else; the recording itself never crosses into your frame. An indicator the app cannot draw is an indicator the app cannot fake. That is worth stating in exactly those terms, because it is the difference between a promise and a property. Most privacy indicators in most software are drawn by the software making the promise. This one is not, and it holds for the same structural reason on surfaces 1 and 2: the chat panel runs on host chrome at the real origin, so the app frame sees neither the key nor the microphone and cannot read the conversation. ## Cost integrity Three mechanisms, all of them about not being able to mislead: - **Two-source reconciliation.** The stream's `usage.cost` first, then the authoritative `/generation` lookup. - **Estimates are labelled and must be rendered as estimates.** `{value, source, estimated}`, and the rule is: render with a `~`, never show one as a bill. - **Images are counted separately**, never folded into the character total, so the ledger stays honest about which calls were the expensive ones. And `usage()` reports the **whole session**, including the host panel's own calls: one bill per session, not one per surface. ## The gap, in the project's own words Not built **CSP egress lockdown.** App frames are not yet served with a `connect-src` that blocks direct network access, so a malicious app could still call an LLM provider itself with its own key. *"The bridge protects **your** key; it is not yet a boundary that prevents all egress. **This is the gap that turns the current design from a convenience into a guarantee.**"* Read precisely what that does and does not say. | | Claim | |---|---| | true | The vault's key is genuinely protected. It never enters the frame. | | true | Spend against the vault's key is genuinely capped, consented and logged. | | not yet | A malicious app can still reach the network with **its own** credential. The bridge is **not** an egress boundary. | The honest scope is "we protect the credential you trusted us with", not "nothing leaves this frame". Those are different claims and only the first is currently true. This site publishes that unsoftened and within one click of the front page, which also carries it. That is the estate's own standard rather than an unusual candour: the vault catalogue publishes its own key-exposure incident, and the house rule on internal documents is that briefs are aspirations rather than facts. A reader who found the brief first would trust a site that omitted this less, and rightly. It is a scope statement rather than a vulnerability disclosure, and this page deliberately carries no exploitation path. The named fix is **Phase 4 minted credentials**: short-lived, budget-capped tokens issued by SG-API, so the vault holds a *reference* rather than a key. The project describes it as *"what would make vault-sharing safe with AI configured"* and as *"the commercially load-bearing piece"*. It is not shipped, and [whether it is scheduled is an open question this site is asking](../admin/comms.md#needs). ## Know what you are storing **With a key configured, the vault contains a credential.** Sharing the vault key shares the ability to spend it. Short-lived minted credentials are planned (Phase 4) and would remove this; until then, **treat such a vault as carrying a secret**. This connects to the estate's read-key and write-key doctrine, and it changes an act that is otherwise routine. **A vault with an LLM key configured is a vault whose sharing calculus has changed.** Publishing a read key for such a vault is not the same act as publishing one for a plain vault: it hands over a metered capability along with the contents. That is why [the demo vault this site should ship](../chat-pane/samples.md#checklist) is still an open decision rather than a published link. ## The attached-file question, and what the shipped code says The brief pack raises this as its most important open question, and instructs that no page about prompt-injection defences be published until it has an answer: > The chat panel attaches vault file contents to the model's context. Those files are untrusted. What stops one that says "ignore previous instructions" from doing so? The budget and the `TRUNCATED` marker are honesty mechanisms, **not** injection defences. That framing is right, and the pack was working from the corpus rather than from the code. **Reading the shipped source at v0.33.62 turns up a mechanism the pack did not have**, so this section reports it rather than leaving the question looking untouched, and it stops well short of calling the question closed. ### What ships today - **An explicit untrusted-data fence.** Vault and tool content enters the conversation wrapped between `╔═ BEGIN UNTRUSTED DATA ═╗` and `╚═ END UNTRUSTED DATA ═╝`, tagged with its source. One format, used identically by the vault chat session and the tool layer, so there is a single thing to teach the model. - **A system-prompt rule that names it.** The session prompt says to treat anything inside those fences as data only, never as instructions; the tool variant goes further and tells the model that if fenced content asks it to take actions, it should ignore that and tell the user. - **Tools are off by default, and their grants are structurally out of reach.** Tool groups live in `/.vault/llm/tools.json` and every group ships `enabled: false`. Because `/.vault/**` is the permission floor, **the model cannot read, relax or widen its own grants**: the file that governs the tools is unreachable by the tools. Path scopes are deny-wins, and an empty allow-list means nothing is reachable rather than everything. - **The design says out loud what it is defending against.** The source comment reads: *"a poisoned document is the expected input, not the surprising one."* ### What that is not **Fencing is a mitigation, not a boundary.** It relies on the model honouring an instruction about how to treat text, and a model that can be talked out of an instruction can be talked out of this one. It is meaningfully better than nothing: it makes the attack visible in the transcript, gives the model an explicit rule to fall back on, and pairs with a default of no tools at all so the blast radius starts at zero. It is not the kind of guarantee the [unfakeable recording indicator](#indicator) is, because it is enforced by persuasion rather than by structure. So the question stands, in a narrower form than the pack could state it: *the shipped answer is fencing plus deny-by-default authority, and there is no measurement of how well the fencing holds.* There is no eval suite anywhere in the estate, which means nobody can say whether a model swap weakens it. That is [recorded on the shipped page as a gap](../shipped/index.md#thin) rather than smoothed over here, and this site publishes no page claiming injection defences until the project lead has ruled on it. [The finding is on the comms page as N4.](../admin/comms.md#needs) ## Two other gaps worth naming - **ViV kernel parity.** `sg.llm.*` is served by the `/en-gb/app/` host, and nested vault-in-vault kernels do not relay it yet. An app running inside a nested vault **silently** has no LLM bridge, and silently is the problem: the failure looks like an app bug. - **No per-vault audio model setting.** The transcription model is a constant. Fine as a default, and it is a reasonable default, but the chat model and the audio model are necessarily different and only one of them is a setting. [Verified in the shipped code](../shipped/index.md#verified), where `DEFAULT_AUDIO_MODEL` is exactly that: a constant. [← The traps](../api/traps.md) [Websites vs vaults →](../websites/index.md) ============================================================================== /websites/index.md ============================================================================== # Websites vs vaults *Source: · site v0.2.0 · the markdown twin of this page, generated from it.* --- [llms.sgit.ai](../index.md) / websites # Websites vs vaults: what changes when there is no host This site was commissioned to cover chat panes on **websites and vaults**. The vault story is shipped, complete and now documented. This one is not. The thin half, labelled **For plain websites there is almost nothing: no component, no documented pattern, and no code.** What follows is a comparison, a recommendation and one adjacent precedent. It is a gap to fill rather than an asset to publish, and levelling it with the vault half would be the single most misleading thing this site could do. ## What a vault gives you that a website does not Everything on [the security page](../security/index.md) depends on **a host at a different origin from the app**. Take the host away and every guarantee changes into something you have to build: | Mechanism | In a vault | On a plain website | |---|---|---| | **Key storage** | `.vault/llm/config.json`, below the permission floor | **nowhere safe in the browser** | | **Who calls the provider** | the host | your page, or your backend | | **Grant model** | `app.json`, default-deny, enforced by the host | nothing enforces it | | **Consent** | host HUD, outside the app's control | you draw it, so you could fake it | | **Budget caps** | host, before the call | your backend, or nothing | | **Recording indicator** | host chrome, **unfakeable by the app** | your own DOM, fakeable | | **Cost ledger** | host, two-source reconciled | you build it | The vault bridge exists because the app and the credential are in different trust boundaries. On a plain website they are not, so the same design does not transfer: the question becomes where you put the boundary instead. ## The three options, honestly compared ### (a) A backend proxy — the standard answer Your server holds the key; the page calls your endpoint. This is the vault model with your own backend playing host. It gets you real key protection, real budget caps and a real ledger, and it costs you a server, an authentication story and an abuse-prevention story that the vault host already solved. Everything on [the four-layer ladder](../security/index.md#ladder) becomes yours to implement, and the two layers people skip are budget and consent. ### (b) Bring-your-own-key in the browser The visitor pastes their own key and it stays in their browser. There is a precedent in the estate: the Regulation Graph vault's Article 9 Lab *requires a bring-your-own OpenRouter key, deliberately, so no metered capability sits behind the published read key*. That reasoning generalises cleanly to a static site. **A public page cannot carry a spending credential, so the visitor brings their own or there is no chat.** It is honest, it costs nothing to run, and it converts badly, which is the whole trade in one sentence. ### (c) Embed the vault surface Point the reader at a vault that already has the panel. Nobody has written this up, and it may be the best option for `*.sgit.ai` specifically: the estate already publishes read keys, already embeds vault content in pages, and the embedding mechanism is built and documented, with a sandboxed iframe, a `postMessage` key handshake, and no key in a URL. **But see the standing warning.** [A vault with an LLM key configured carries a credential](../security/index.md#storing), so publishing a read key for it shares the ability to spend it. Option (c) works only for a vault whose key tier and spend caps were chosen with publication in mind, which is a decision to take before publishing rather than after. ## The recommendation | Context | Option | Why | |---|---|---| | A product | **(a) backend proxy** | You need the caps and the ledger, and you will need the auth story anyway | | A `*.sgit.ai` page | **(c) embed the vault surface** | The mechanism exists, the estate already uses it, and it reuses guarantees rather than reimplementing them | | A public demo or lab | **(b) BYOK** | The Article 9 Lab's reasoning, and the only option that never puts a spending credential behind a public link | The concrete artefact this section still needs is a **`sg-llm-chat` web component with a pluggable transport**, so one component serves all three, built to the estate's component conventions. The versioned component CDN already serves `sg-vault-client.js` and `sg-vault-write.js`, so it is a natural next member of that family rather than a new idea. **It is not built**, and it is [on the shipped page's list of absences](../shipped/index.md#thin) rather than described here as though it were. The nearest existing worked example is small and real: an **offline Ollama chat UI** from March 2026, a chat interface over a FastAPI proxy, built on the `sg-layout` web component. That is option (a) in miniature, and [it is on the local models page](../local/index.md). ## The one thing that transfers unchanged None of the honesty mechanisms depend on a host. Every one of them is available to a chat pane with no vault behind it at all: - one shared context budget, never one per file - `TRUNCATED` in the text the model sees - estimates rendered with `~`, never as a bill - images cleared after one send - `available()`, or its equivalent, before rendering - branch on error codes, not message text - recording announced in words A website chat pane built without these is worse than a vault one for reasons that have nothing to do with key storage. [The pre-ship checklist](../chat-pane/samples.md#checklist) applies verbatim, minus the two lines about grants. ## The other sense in which a website serves an LLM There is a second reading of this page's title, and it is the half most sites forget. [Putting a model inside your page](../chat-pane/index.md) is one subject. [Making your page readable to a model that arrives from outside](../agents/index.md) is the other, and this estate has a real practice for it: `/llms.txt` on every site, a markdown twin at every URL, and filenames that say `for_llms` out loud. It also has a finding that reads as a warning: *"It can read the map and cannot walk it."* [That page](../agents/index.md) is the other half of this one. [← The security model](../security/index.md) [Provenance →](../provenance/index.md) ============================================================================== /provenance/index.md ============================================================================== # Provenance: the oldest thread *Source: · site v0.2.0 · the markdown twin of this page, generated from it.* --- [llms.sgit.ai](../index.md) / provenance # Provenance: the oldest thread Everything else on this site is a mechanism. This is the position the mechanisms serve, and it is older than any of them. ## June 2024 The earliest dated artefact in the entire estate is a talk: **Deterministic GenAI Outputs with Provenance**, OWASP AppSec Lisbon, **28 June 2024**. Nearly ten thousand words of slides and notes, published openly. Two years later the same instinct runs through everything built since. Provenance is mentioned in 431 files across the corpus and determinism in 421. The chat panel logs an OpenRouter generation id on every call. The Regulation Graph vault carries a SHA-256 of the retrieved bytes on every node. The grounding ladder terminates a claim at a measure. None of that was planned as a programme; it is what happens when one instinct is applied for two years. The position is not "models are unreliable, use a better one". It is "a model output is only usable when you can say where it came from". The distinction is practical rather than philosophical. The first framing sends you shopping for models. The second sends you building the apparatus that makes an answer checkable, which is what got built. ## Grounding, not prompting Hallucination appears in only 45 files in the corpus, and where it does, it is framed as a **grounding** problem rather than a model problem. The answer the estate reaches for is the grounding ladder, in which each rung is defined by what lies below it: ``` Risk := a downward path to a Vulnerability AND an upward path toward a top risk Vulnerability := a Fact (grounded below) AND an upward path to a Risk Fact := a downward path to Evidence Evidence := a downward path to a Measure Measure := an observation of the node it measures, grounded on a Twin ``` The anti-fabrication argument follows directly: > A model asked to assess something will produce a plausible answer. A model asked to attach a finding to a provision hash, and to a measure, and to a twin, either finds the path or reports that it cannot. **The ladder is not this site's to own.** It belongs to [risks.sgit.ai](https://risks.sgit.ai) and [standards.sgit.ai](https://standards.sgit.ai), which carry it as risk apparatus and as instrument citation respectively. Three lines and a link out is the right amount of it here, because it is the *reason* the LLM work looks the way it does rather than the subject of this site. If a page here starts explaining the ladder, it has wandered. ## Where the position shows up in the shipped work Read the LLM bridge with provenance in mind and the design choices stop looking like polish: | Mechanism | What it is really doing | |---|---| | **An OpenRouter generation id on every call** | Making a specific answer re-findable at the provider, months later, by someone who was not there | | **Two-source cost reconciliation** | Refusing to let a computed number stand where a billed one is available | | **`TRUNCATED` in the model's own input** | Recording, inside the artefact, that the input was incomplete | | **Images counted separately in the ledger** | Keeping the record honest about which calls were expensive | | **The untrusted-data fence** | Marking, in the transcript, which text came from a file rather than from a person | | **CSV and JSON export of the request ledger** | Making the record leave the tool that produced it | Every one of those is the same move: attach an output to where it came from, and make the attachment survive the session. ## The one-shot thread A related strand runs from early 2026: **one-shot** generation, in which a model produces a complete artefact in a single pass. It is attractive for the same reason it is risky, and the corpus works both sides: the one-shot development environment as a tool, and a published article on one-shot output as a thing to be careful with. The determinism problem is the joint between them, and it is the reason a generation id matters more than a good prompt. ## And the thing the position does not yet have **There is no eval suite anywhere in the estate.** No benchmark, no regression test for prompt behaviour, nothing that would catch a model swap changing an output. For a body of work whose whole thesis is *you must be able to say where an output came from*, there is no mechanism for saying whether an output was any good, or for noticing when it stops being. [It is the most conspicuous absence on this site](../shipped/index.md#thin), and it is named here rather than only there because this is the page where it contradicts something. [← Websites vs vaults](../websites/index.md) [The provider layer →](../openrouter/index.md) ============================================================================== /openrouter/index.md ============================================================================== # The provider layer *Source: · site v0.2.0 · the markdown twin of this page, generated from it.* --- [llms.sgit.ai](../index.md) / openrouter # The provider layer OpenRouter is mentioned in 442 files in this corpus and it is the estate's actual model-access path. Nobody had written up why, so this page does, including what it costs. ## Why route through an aggregator at all | What you gain | What it costs | |---|---| | **One key for many models.** A vault holds a single credential and reaches every vendor through it | **One credential to lose.** The blast radius of that key is every model rather than one | | **Capability metadata for free.** Whether a model reads images, whether it accepts audio, what it costs, all from the catalogue | **You trust somebody else's catalogue** for a check you are making before spending money | | **Generation ids.** A stable handle per call, reconcilable afterwards against an authoritative lookup | **The handle is theirs.** Provenance that depends on a third party's record-keeping | | **Model switching is a string.** `models.allow` takes globs, so `anthropic/*` is a policy | **A single point of dependency** between you and every model you use | That last row is the real trade and it deserves naming rather than burying: the aggregator is a dependency with the reach of all of them at once. [The local-models page](../local/index.md) is the other half of this thought, and [the sovereignty argument](https://open-source.sgit.ai) applies to model providers more sharply than to almost anything else, because *you are one SLA away from losing access* is not hypothetical for a hosted model. ## Bring your own key, per vault The key is the vault owner's, not a platform key. That single choice explains a surprising amount of the design: [the two key tiers](../security/index.md#tiers), the per-vault spend caps, the [standing warning about what a configured vault now contains](../security/index.md#storing), and the fact that [Phase 4 minted credentials](../security/index.md#gap) are described as the commercially load-bearing piece. A platform key would have made most of that somebody else's problem, and would have made every vault a shared spending surface. ## Capability comes from the live catalogue Whether a model can read an image is read from the catalogue at call time, from the model's own declared modalities, rather than from a hard-coded list. A new vision model works the day it ships. Two consequences worth having: a model that cannot see gets you `EMODEL` **naming the model**, rather than a provider error that names nothing; and `text->image` models are correctly refused, because an image *generator* is not an image *reader* and the modality string says so. ## Defaults are a design decision With no `models.default` configured, the panel auto-picks. The story of how it picks is the best small lesson on this site. The bug It used to match on the **vendor prefix** against an alphabetically sorted list of the models on the key. Alphabetically, `anthropic/claude-3-haiku` comes early. So the picker selected **the oldest model on the key, which was also not a vision model**, silently, on every vault that had not set a default. The symptom presents as *"the AI is bad"* rather than *"the default is wrong"*, and a pasted screenshot would fail with a model error nobody connected to the default. The fix, in the shipped code today, is an explicit ordered list of named models tried first, with the vendor-prefix match kept only as a fallback for a key that has none of them: ``` var PREFERRED_MODELS = [ 'anthropic/claude-sonnet-5', 'anthropic/claude-opus-5', 'anthropic/claude-sonnet-4', 'google/gemini-3.5-flash', 'openai/gpt-5' ]; // Vendor fallback, when none of the named models are on this key. var PREFERRED = ['anthropic/', 'openai/', 'google/', 'meta-llama/', 'mistralai/']; ``` These are exact ids, so a rename drops through to the vendor fallback rather than pinning a model that no longer exists. [Verified against the shipped source at v0.33.62](../shipped/index.md#verified), because a list like this is exactly the kind of thing a site gets wrong by quoting a brief. A default that is silently wrong is worse than a default that is absent, because nobody goes looking for it. An explicit `models.default` and a `models.allow` list still beat any auto-pick. The general lesson is the one the incident teaches: **a sort order is not a preference order**, and any time the two are confused the result is a system quietly choosing the wrong thing with complete confidence. ## Generation ids, and the analysis nobody has done Every call is logged with its generation id, tokens, cost and latency, and the whole ledger exports as CSV or JSON. Cost is reconciled two-source: the stream's own figure first, then the authoritative lookup. **And nobody has looked at it.** `cost per token` appears in **two** files across the corpus, and `model routing` in **one**. There is no fallback chain, no cost or quality tiering, and no routing logic, despite a fully instrumented ledger that has been collecting exactly the data those decisions would need. [The instrumentation is better than the use made of it](../shipped/index.md#thin), which is a more interesting failure than having neither. [← Provenance](../provenance/index.md) [Local and offline →](../local/index.md) ============================================================================== /local/index.md ============================================================================== # Local and offline models *Source: · site v0.2.0 · the markdown twin of this page, generated from it.* --- [llms.sgit.ai](../index.md) / local # Local and offline models Ollama appears in 144 files in this corpus, and behind them are three concrete artefacts rather than an intention. ## The offline chat, and the flight it was built for March 2026: a chat UI plus a FastAPI proxy to a host-native Ollama, with sessions surviving container rebuilds, built on the same `sg-layout` web component the vault UI uses. The stated requirement is disarmingly specific and it is the reason the thing is any good: > Offline LLM chat during travel (flight on 19 March 2026). Must work completely disconnected from the internet once the Docker image is built and Ollama models are pulled. A requirement with a date in it produces a different artefact from a requirement with a principle in it. "Must work offline" gets argued about; "the flight is on the 19th" gets built. ## Two sg-compute workload specs | Spec | Class | Size | Boot | Status | |---|---|---|---|---| | `ollama` | llm-inference | 939 LOC | 120s | EXPERIMENTAL | | `local_claude` | llm-inference | 1,498 LOC | 180s | EXPERIMENTAL | Each carries a manifest, a CLI, a service, schemas and tests. There is also a `docker/local-claude` image: a local model alongside a Claude Code harness. **The specs are not this site's to own.** [sg-compute.sgit.ai](https://sg-compute.sgit.ai) owns the workload specs and their lifecycle. This page links to them for the local-model story and does not duplicate them, in the same way [the grounding ladder](../provenance/index.md#grounding) is stated in three lines and left to the site that owns it. ## The through-line The same `/api/chat` proxy shape works against a local Ollama and against a remote tunnel, which is why the offline work was never a detour. That also makes the offline chat the estate's clearest existing example of [option (a), the backend proxy](../websites/index.md#options), on the websites page: a chat UI whose transport is an endpoint you control. It is small, it is real, and it is closer to a website chat pane than anything else that exists here. ## Why this matters more for models than for most dependencies The open-source position in this estate is that *you are one SLA away from losing access*. For most dependencies that is a slow problem: a library can be forked, a service can be migrated over a quarter. For a hosted model it is not slow and it is not always about outages. A model can be deprecated, re-tuned, re-priced, or restricted by policy, and your outputs change underneath you without anything failing. [The provenance thread](../provenance/index.md) is what makes that visible: if you logged the generation id and the model, you can at least tell when the ground moved. A local model is worse at almost everything and it is **yours**. That is the trade, stated plainly, and this estate has taken both sides of it deliberately: [an aggregator for reach](../openrouter/index.md), local for the case where reach is not available. [← The provider layer](../openrouter/index.md) [Pages that models read →](../agents/index.md) ============================================================================== /agents/index.md ============================================================================== # Pages that models read *Source: · site v0.2.0 · the markdown twin of this page, generated from it.* --- [llms.sgit.ai](../index.md) / agents # Pages that models read The rest of this site is about putting a model inside your page. This page is the other half of the same subject: making your page readable to a model that arrives from outside. For a site called `llms.sgit.ai` it is not a topic, it is an acceptance criterion. ## What this site publishes for a machine reader | Surface | What it is | Guaranteed by | |---|---|---| | [/llms.txt](../llms.txt) | The map: what this site holds, stated in full rather than as a list of links | Written by hand, version-stamped by the build | | [/llms-full.txt](../llms-full.txt) | **The whole site in one fetch**, every page plus the brief pack it was built from | Generated from the twins, so it cannot disagree with the site | | A `.md` twin at every path | Any page, extension swapped: `/security/index.html` → `/security/index.md` | **The pre-release gate fails the build if one is missing or stale** | | [/sitemap.xml](../sitemap.xml) | Every page **and every twin**, so a crawler that only reads the sitemap still finds the markdown | Generated from the tree | | [/briefs/](../briefs/00__BRIEF.md) | The brief pack, verbatim, at stable constructed paths | Published as source, not as a rendering | Links inside a twin point at twins. An agent that enters the markdown never has to step back out into HTML to follow a reference, which is the property that makes the twins a surface rather than a courtesy. ## The mechanism, and why this site's differs Across the estate the markdown twin is served at request time by a **Lambda@Edge function**, because the origins are static files and a static file cannot render itself. It is a genuinely non-obvious piece of plumbing, and it is invisible if you only look at a repository. This site has no such function in front of it. It is GitHub Pages, so the twins are **written into the tree at release** by `admin/build/gen_twins.py` and served as ordinary files. Same contract, different machinery, and the difference is worth stating because a reader copying the convention needs to know which half they are copying. ## Writing for a model, and saying so in the filename The estate writes documentation explicitly for model readers and puts it in the path: ``` library/dependencies/osbot-utils/type_safe/v3.1.1__for_llms__type_safe__testing_guidance.md ^^^^^^^^^ ``` When a model is a primary reader, write it a document rather than expecting it to parse yours. That is a different discipline from making HTML machine-friendly. Structured data helps a parser; a document written for a model reader answers the questions that reader actually arrives with. The `for_llms` convention is the estate admitting out loud who the audience is. ## The finding this site is built against Agent-access report, 14 August 2026 **"The audience is disproportionately agents."** And: many agents can only fetch URLs that a search engine has already returned to them, so a site that is not indexed is a site they cannot reach even when they know its address. *"It can read the map and cannot walk it."* The report's subject was the whole estate, and the diagnosis generalises past this network: **excellent documentation that cannot be reached is not published**. It is the same shape as this site's other founding problem, in which the complete `sg.llm.*` contract existed only inside a 9,487-word agent authoring file that no human would open. Different reader, same failure: the quality was never the problem, the discovery layer was. So the acceptance criteria for this site, taken from that finding rather than invented: - **`/llms.txt` is self-sufficient**, not a list of links to fetch. An agent that reads only that file should be able to say accurately what this site holds and does not hold. - **`/llms-full.txt` exists.** `pki.sgit.ai`, the site this one copies its pattern from, does not have one. One fetch returns everything. - **The twin works at every path**, and the build fails if it does not. - **The status is stated plainly enough to be quoted.** If an agent summarises this site, the parts that are not built should survive the summary: [the CSP gap](../security/index.md#gap), [the absent evals](../shipped/index.md#thin), [the thin website half](../websites/index.md). ## If you are copying this 1. Write `llms.txt` as a document, not an index. The link list is what a sitemap is for. 1. Ship the twin at the same path with the extension swapped, and rewrite links inside it to point at twins. 1. Concatenate everything into one file. The cost is a few hundred kilobytes; the benefit is that a single fetch cannot miss a page. 1. Put your limitations where a summariser will find them. A caveat in a footnote does not survive being summarised. 1. Enforce it in the build. A convention that depends on somebody remembering is one that lasts about four pages. The component and page conventions themselves belong to [coding.sgit.ai](https://coding.sgit.ai), which owns how code and pages are written across the estate; this page owns only the LLM-reader half of it.

This page is the shipped list unsoftened, the absences with their sizes, and the claims this site checked for itself rather than repeating. ## Shipped Quoted from the capability brief of 2 August 2026, and it is an unusually complete list for something that had no public documentation until this site: Shipped The shared engine (`SGLlm`), vault key and policy resolution (`SGLlmVault`), the admin settings panel, the host-native chat panel (multi-file, params, ledger, **voice**, **pasted screenshots**) on **both** `/vault` and `/en-gb/app/`, and the `sg.llm.*` bridge with permission, consent, budget, streaming, cancel, `listen` and `imagePart`. Since then, and not in that brief: an **opt-in tool layer** for the vault's own chat, with tool groups that ship disabled, path scopes where deny wins, and grants stored in a file the tools structurally cannot reach. [It is described on the security page](../security/index.md#injection), because the reason it exists is the injection question. ## Not built, and one item is load-bearing | Item | What it means today | |---|---| | **CSP egress lockdown** | App frames are not served with a `connect-src` that blocks direct network access, so a malicious app could still call a provider itself with its own key. *"The bridge protects your key; it is not yet a boundary that prevents all egress. This is the gap that turns the current design from a convenience into a guarantee."* [In full](../security/index.md#gap) | | **Phase 4 minted credentials** | Short-lived, budget-capped tokens so the vault holds a *reference* rather than a key. Described as what would make vault-sharing safe with AI configured, and as *"the commercially load-bearing piece"*. Whether it is scheduled is [an open question this site is asking](../admin/comms.md#needs) | | **ViV kernel parity** | Nested vault-in-vault kernels do not relay `sg.llm.*`. An app inside a nested vault **silently** has no bridge | | **A per-vault audio model setting** | The transcription model is a constant. Reasonable as a default; not configurable when it should be | | **The `sg-llm-chat` web component** | Half the commission. No component, no documented pattern, no code for a chat pane on a plain website. [The options, compared honestly](../websites/index.md) | | **The demo vault that is the documentation** | One app exercising every call, published as both the demo and the test, so [the samples](../chat-pane/samples.md) would be verified by existing rather than by review. Blocked on a real decision: [a vault with a key configured carries a credential](../security/index.md#storing) | ## The thin threads, with their sizes Measured across the corpus. The counts are from the brief pack, dated 24 August 2026, and are quoted as a dated measurement rather than presented as a standing fact. | Topic | Files | What that means | |---|---|---| | **Evals** | **0** | No eval suite, no benchmark, no regression test for prompt behaviour. Nothing would catch a model swap changing an output. **The most conspicuous absence here**, and it sits directly against [a thesis about provenance](../provenance/index.md) | | **Model routing** | **1** | One mention. No fallback chain, no cost or quality tiering, no routing logic | | **Cost per token** | **2** | Despite a full two-source reconciled ledger with CSV export. [The data exists and nobody has looked at it](../openrouter/index.md#ledger) | | **Structured output** | 41 | `Type_Safe` validates the *result*; nothing documents how the *request* is shaped to get a valid one | | **Hallucination** | 45 | Mostly framed as a grounding problem rather than a model problem, which is a position rather than a gap | | **Embeddings** | 100 | Mentioned. No vector store, no retrieval implementation | | **Prompt injection** | 92 | Real, and concentrated in the agent-to-agent and sentinel clusters. [What ships against the case this product creates](../security/index.md#injection) | Three of these are load-bearing: evals, structured output and model routing are the difference between a working integration and an engineered one. ## What this site checked for itself The brief pack's own closing instruction was to verify its claims against the shipped code rather than only against the contract, since the API is young and moved twice in two days. This site did, at product version **v0.33.62**. | Claim | Result | |---|---| | Base64 chunked at 8190, not 8192 | confirmed in the shipped encoder, with the arithmetic in a comment | | One 24,000-character budget shared across attached files | confirmed: `MAX_CONTEXT_CHARS = 24000`, commented as the total across *all* files | | The default-model list, after the alphabetical-picker bug | confirmed, and [quoted exactly](../openrouter/index.md#defaults) rather than from the brief | | `hud.show.llm` is still the config key, off by default in `minimal` | confirmed, with per-mode defaults intact | | The transcription model is a constant | confirmed: a `DEFAULT_AUDIO_MODEL` constant, with a fixed list of accepted audio models | | The attached-file injection question is unaddressed | superseded: a fenced untrusted-data mechanism ships. [What it does and does not promise](../security/index.md#injection) | | "There is no tool-calling loop" | no longer true: see below | ## One place where the contract and the code disagree Contract drift The canonical authoring contract states, in the section [this site generates its reference from](../api/index.md): *"There is no tool-calling loop. `sg.llm.chat` is a **reader**: it takes messages and returns text."* That is still true of `sg.llm.chat`, the bridge an app calls. It is **no longer true of the product**: the vault's own chat panel ships an opt-in tool layer with a bounded tool loop, read-tier groups for the session ledger and for reading files, and per-group path scopes. Both statements can be true at once, and a reader of the contract alone would not know the second one exists. That is not a bug in either place; it is what happens when a contract for app authors and a product feature move at different speeds. It is recorded here because [this site generates its reference from that contract](../api/index.md), so anything the contract does not say, this site does not say either, unless it says so here. Reported to the project lead as [N5](../admin/comms.md#needs). ## The open questions, published unresolved The brief pack carries eight, and the estate's habit is to publish them open rather than settle them quietly. Their current state on this site: | | Question | Where it stands | |---|---|---| | Q1 | How does a public reference avoid becoming a second source of truth? | answered by mechanism: [the reference is generated from the canonical contract](../api/index.md) and the gate fails if it drifts | | Q2 | Who owns the `/vault` chat-panel page, this site or `sgit.ai`? | proposed: this site owns the capability, `sgit.ai` owns the product tour.

The network's own access review found three sites each holding a third of one answer and unjoined at the page level, so every cross-reference on this site points at a page. ## What this site borrowed, and from where - **The pipeline and the house pattern** from [pki.sgit.ai](https://pki.sgit.ai): validate, tag, deploy, with a validation failure stopping the release entirely. [How it runs here](../admin/index.md). - **Two pipeline improvements** from [graphs.sgit.ai](https://graphs.sgit.ai): anchoring the tag on the newest release commit reachable from `HEAD`, and checking the remote before pushing backfill tags. - **A link-checker fix** from [standards.sgit.ai](https://standards.sgit.ai): strip query strings as well as fragments. - **The honest-limitations posture** from all of them. The vault catalogue publishes its own key-exposure incident; this site publishes [the gap in its own security design](../security/index.md#gap). And one thing it adds that none of them has: **[llms-full.txt](../llms-full.txt) and a markdown twin at every path, enforced by the build**. [Why that is an acceptance criterion here rather than a nicety.](../agents/index.md) [← What is shipped](../shipped/index.md) [Where we lose →](../about/participant.md) ============================================================================== /about/participant.md ============================================================================== # Participant disclosure, and where we lose *Source: · site v0.2.0 · the markdown twin of this page, generated from it.* --- [llms.sgit.ai](../index.md) / about / participant # Who is writing this, and where we lose Published upfront rather than discovered later. A reader who finds out about an affiliation afterwards discounts everything they have already read; a reader told at the start can judge the work as it goes. ## Who is writing this This site is published by the **sgit project**: encrypted vaults with git workflows, for humans and AI agents. The chat pane described here is the project's own feature, the `sg.llm.*` bridge is the project's own API, and the security model is the project's own design. **This is a participant documenting its own product.** What makes that worth reading anyway is narrower than "trust us", and it is worth being precise about which parts do not depend on trusting us: - **The contract is checkable.** [The reference](../api/index.md) is generated from a canonical file in a public repository, with the source hash on the page, so you can diff this site against the thing it describes. - **The traps are our own mistakes.** [A bug that shipped three times](../api/traps.md#chunking) and [a default that silently picked the worst model on the key](../openrouter/index.md#defaults) are published because they are the useful part, not despite being embarrassing. - **The limit is stated in the project's own words.** [The CSP gap](../security/index.md#gap) is quoted from an internal capability brief rather than paraphrased into something softer. ## Where our own approach loses A site that only names other people's limits is not research. So, plainly, on this subject: - **The bridge is not an egress boundary.** [The whole of it.](../security/index.md#gap) If your threat model includes a hostile app in the frame, this design protects your credential and does not contain the app. - **A configured vault carries a credential, and that changes what sharing means.** [Publishing a read key for such a vault hands over the ability to spend.](../security/index.md#storing) The fix is planned and not shipped. - **Fencing untrusted files is a mitigation, not a guarantee.** [It relies on the model honouring an instruction](../security/index.md#injection), and there is no measurement of how well it holds. - **There are no evals.** None. A body of work whose thesis is that you must know where an output came from has no mechanism for knowing whether it was any good. [The absence, sized.](../shipped/index.md#thin) - **Half the commission is thin.** [Chat panes on plain websites](../websites/index.md) is three options and one adjacent precedent. The vault half is shipped and complete; the website half is a gap, and this site says which is which rather than levelling them. - **The samples are read, not run.** [They are verified by review rather than by existing](../chat-pane/samples.md), which is exactly the weaker of the two, and the artefact that would fix it is blocked on a decision nobody has taken. - **We are not neutral about agents.** The parent project's answer to most questions involves vaults, versioning and agents in the loop. That is a real position and not the only one. - **The corpus counts are a dated snapshot.** 442 files mentioning OpenRouter, 92 mentioning injection, 2 mentioning cost per token: measured on 24 August 2026, quoted rather than re-measured, and they will drift. ## Licensing | What | Licence | |---|---| | The content of this site, and [the brief pack](../briefs/00__BRIEF.md) it was built from | **CC BY 4.0**, Dinis Cruz, with AI co-authorship | | Code quoted from `SGraph-AI__App__Send`, including [the generated API reference](../api/index.md) and the vault-html guides | **Apache-2.0**, and it keeps its own notice | | [The samples](../chat-pane/samples.md) | **Mixed, and the page says which is which:** the `sg.llm.*` calls are the shipped contract; the surrounding UI was written for this site and is CC BY 4.0 | That distinction is not pedantry. A reader copying a sample needs to know which half is a contract they can rely on and which half is one example among many. ## The people and agents behind the site The project lead is Dinis Cruz. This site is built and maintained with AI agents in the loop, which is a reasonable thing for a site about language models to do and also a reason to check its citations rather than trust them. [The comms page](../admin/comms.md) is the working channel between the project lead and the site agent, kept in public, including the questions this site is currently asking and cannot answer for itself.

The full statement is in [the pack licence](licence.md). Code quoted inside the documents from `SGraph-AI__App__Send` is **Apache-2.0** and keeps its own notice: in the samples, the `sg.llm.*` calls are the shipped contract and the surrounding UI was written for the pack. [← Front page](../index.md) [What is shipped →](../shipped/index.md) ============================================================================== /admin/index.md ============================================================================== # How this site is built · llms.sgit.ai *Source: · site v0.2.0 · the markdown twin of this page, generated from it.* --- [llms.sgit.ai](../index.md) / admin # How this site is built Static HTML in the sgit.ai design language, released the same way as the rest of the network: every push to `dev` is validated, auto-tagged, and deployed to GitHub Pages. The pipeline shipped one release before the content did, so every release since has gone through a gate that was already proven. ## The release pipeline 1. **validate** — `node admin/build/validate.js`: internal links resolve, the version agrees everywhere, every page declares a canonical URL on the host named in `CNAME`, every `` in the sitemap is on that host and has a file behind it, and a key-leak tripwire bans anything shaped like a vault key from the tree. A failure stops the release: no tag, no publish. It also runs on pull requests, so branch work is gated before it reaches `dev`. 1. **tag-release** — every push to `dev` ends tagged `v{release}.{major}.{minor}`. The version is owned by `admin/build/version.txt`, bumped exactly once per release, and must agree with the release commit's subject (`site vX.Y.Z: ...`). CI verifies the two agree and that the bump is the next minor (or a deliberate major), then tags the release commit — which is `HEAD` on a direct push and `HEAD`'s parent when a pull request lands as a merge commit. The first run backfills tags for any historical release from the commit subjects. 1. **deploy** — publishes the tagged working tree to GitHub Pages. Runs on manual dispatch even without a tag, never when validation failed, never from a pull request. **Why this order, and why it ships first.** The gate is upstream of the tag and the tag is upstream of the publish, so a site that contradicts itself never reaches a reader and never acquires a version number that says it did. Shipping that before the first page of content means every later release goes through a mechanism that has already been proven on a real deploy rather than on the release that mattered. ## The eleven checks Five came from [pki.sgit.ai](https://pki.sgit.ai). Six were added here, and most of them are conditions the brief pack stated as instructions. **A condition in a brief is one somebody forgets on the fourth page; a condition in the pre-release gate is one the build enforces.** | # | Check | What it catches | |---|---|---| | 1 | **Version agreement** | A version badge, a release-history row, `llms.txt` or `index.md` that disagrees with `admin/build/version.txt`, and a history table that lists the same release twice. | | 2 | **Internal links** | Any relative `href` or `src` with no file behind it. Fragments and query strings stripped before resolving. | | 3 | **Canonical host** | A page with no ``, or one pointing at a host other than the one in `CNAME`. | | 4 | **Sitemap targets** | A `` on the wrong host, or naming a file that does not exist. | | 5 | **Key-leak tripwire** | A vault-key-shaped string, key material after the `sgit_vk1_` write prefix, **an OpenRouter `sk-or-` key**, or a bare 48-plus-character secret-shaped token. **Every page on this site is about credentials, which makes it the most likely place in the estate for one to end up in a sample.** The prefixes may appear in prose, because explaining why a key is never published requires naming it; material after them may not. | | 6 | **The generated reference matches its source** | [The API reference](../api/index.md) is generated from a vendored copy of the canonical contract. If the source changes and the page is not regenerated, or the page is hand-edited, the recorded hash stops matching and the build fails. **This is how the site keeps a readable reference without becoming a second source of truth.** | | 7 | **A markdown twin at every path** | A page with no `.md` twin, or a twin that has gone stale against its page. Not a nicety on this site: [an inherited finding made it an acceptance criterion](../agents/index.md#finding). | | 8 | **Twins point at twins** | A link inside a twin that still points at `.html`, which would push a traversing agent back out into markup. | | 9 | **`llms-full.txt` is current** | The single-fetch file lagging the twins it is built from. | | 10 | **The qualification travels with the claim** | The front page making the never-holds-a-key claim without [the CSP-gap qualification on the same page](../security/index.md#gap). The brief's instruction was not to soften it and not to bury it; this check is what makes that survive a future edit. | | 11 | **House spelling** | `-ize` where the house style is `-ise`, in any page or markdown deliverable. | ## What is generated, and what is written Pages are hand-written static HTML, with four exceptions, and each exception exists for a stated reason rather than for convenience. | Output | Generator | Why it is not written by hand | |---|---|---| | [api/index.html](../api/index.md) | `gen_api.py` | **The Q1 answer.** The canonical contract lives in `AUTHORING.md`, and the corpus refused to copy it because a competing document drifts. Generating it, recording the source hash and gating on the match gives a readable public reference with exactly one author. | | A `.md` twin per page | `gen_twins.py` | Across the estate these are rendered at request time by a Lambda@Edge function. This site is GitHub Pages with nothing in front of it, so they are written into the tree at release. | | [llms-full.txt](../llms-full.txt) | `gen_llms_full.py` | Built from the twins, so the one-fetch file cannot disagree with the site. `pki.sgit.ai` has no equivalent; on a site called `llms.sgit.ai`, it is not optional. | | [documents/](../documents/index.md) | `gen_documents.py` | A repetitive family of reader pages over `briefs/`. The raw markdown stays the source of truth and each page renders it at read time rather than copying it. | | [sitemap.xml](../sitemap.xml) | `gen_sitemap.py` | The only claim on a site that nothing renders, so it drifts silently. It lists the twins too. | **No third-party dependency in the toolchain.** The sibling sites reach for `markdown-it` and BeautifulSoup; this one carries `admin/build/mdlite.py`, a markdown subset in both directions, in about 300 lines of standard library. The release path is `python3 admin/build/*.py` on a clean machine, and a generator that needs `pip install` first is a generator that stops being run. ## Releasing a change ``` # 1. bump the version - exactly once per release echo "v0.2.1" > admin/build/version.txt # 2. add a row to admin/versions.html, update admin/comms.html # 3. regenerate, in this order - each step reads the one before it python3 admin/build/gen_api.py # the reference, from the vendored contract python3 admin/build/gen_documents.py # the reader pages over briefs/ python3 admin/build/chrome.py # nav, footer, version badge, everywhere python3 admin/build/gen_twins.py # a markdown twin per page python3 admin/build/gen_sitemap.py # from the tree python3 admin/build/gen_llms_full.py # from the twins # 4. validate locally - the same gate CI runs node admin/build/validate.js # 5. commit with the version in the subject, push to dev git commit -am "site v0.2.1: what changed" git push origin dev ``` The order matters and the gate enforces the consequences of getting it wrong: `chrome.py` stamps the version the twins then carry, and `gen_llms_full.py` reads the twins, so running them out of order leaves a stale artefact that checks 7 to 9 will catch. ## Chrome from one definition Pages are hand-written static HTML and stay that way — a human should be able to open any file in the repo and edit it. What is not hand-maintained is the chrome: the nav row (including the version badge `validate.js` requires to agree everywhere) and the footer columns are defined once in `admin/build/chrome.py` and rewritten in place across the tree. Adding a page means adding it to `NAV` or `FOOTER` if it belongs there, writing the file with an empty `` and `
`, and running the script — the `here` state comes from the page's own path. The same script stamps the version and release date into `llms.txt` and `index.md`. On the sibling sites nothing did, so they were hand-edited every release, and hand-editing them silently missed. ## Conventions carried from the network - Light theme, the same design tokens and the same honest-limitations posture as [sgit.ai](https://sgit.ai), [pki.sgit.ai](https://pki.sgit.ai) and [graphs.sgit.ai](https://graphs.sgit.ai). - The version badge in the nav links to the release history, so any page tells you which release you are reading — and CI enforces that they all agree. - The stage pill states the site's maturity in the nav rather than in a footer nobody reads. It says **reference draft**: the contract it documents is young, moved twice in two days when it shipped, and [already disagrees with the product in one place](../shipped/index.md#drift). - Source documents captured verbatim under `briefs/` with a curated reader page alongside — the raw markdown stays the source of truth. Queued: this site has no source documents yet. - Machine-readable entry points: `llms.txt`, [llms-full.txt](../llms-full.txt), a twin at every path, and a sitemap that lists both. [Why this site treats that as an acceptance criterion.](../agents/index.md) - The comms page is the working channel between the project lead and the site agent, in public, updated every release. ## One thing worth fixing upstream **The inherited `.gitignore` hides the build tooling.** These repositories start from the standard Python `.gitignore`, which ignores `build/` — and that matches `admin/build/`, so the gate script and the chrome script are silently never committed. [standards.sgit.ai's repository](https://github.com/SGit-AI/SGit-AI__Website__Standards) is in that state today: its CI runs `node admin/build/validate.js` against a checkout that does not contain the file. The fix is one line — `!admin/build/` immediately after `build/` — which [pki](https://github.com/SGit-AI/SGit-AI__Website__PKI) and [graphs](https://github.com/SGit-AI/SGit-AI__Website__Graphs) carry and this repository now carries too.

Updated on every release. Current release: **v0.2.0**, 25 August 2026. Full history: [versions](versions.md). ## Needed from the project lead | # | Request | Why it blocks | Status | |---|---|---|---| | N4 | **Rule on Q3, now that it has moved.** The pack calls the attached-file injection question the most important open question on the site and instructs that no injection page ship until it is answered. Reading the shipped source at v0.33.62 turns up a mechanism the pack did not have: an explicit `BEGIN/END UNTRUSTED DATA` fence around vault and tool content, a system-prompt rule telling the model to treat fenced text as data and to report anything inside it that asks for action, tool groups that ship `enabled: false`, and grants stored in `/.vault/llm/tools.json` where the tools structurally cannot reach them. [Published as a narrowing rather than an answer](../security/index.md#injection), because fencing is enforced by persuasion and nothing measures how well it holds. **Two calls are yours:** whether that is enough to lift the HOLD on the injection material in the source manifest, and whether the fencing claim may be stated more strongly than this site currently states it | The `/injection/` page and two tier-2 manifest rows stay held until you rule | waiting on human | | N5 | **The contract and the code disagree about tool calling.** `AUTHORING.md` says *"There is no tool-calling loop. `sg.llm.chat` is a reader."* That is still true of the bridge and **no longer true of the product**: the vault's own chat ships an opt-in tool layer with a bounded loop, read-tier groups and per-group path scopes. Both statements are individually correct, and a reader of the contract alone would not know the second exists. Since [this site generates its reference from that contract](../api/index.md), the drift propagates here by design. **Recommendation:** a paragraph in the contract's own "What this is not" section, pointing at the tool layer as a separate, non-app-facing capability | Not blocking. It is [recorded on the shipped page](../shipped/index.md#drift) and will keep being recorded until the contract moves | reported | | N6 | **The demo vault, and whether it can publish a read key at all** (pack Q4). The pack's own recommended artefact is a vault app that exercises every call, published as both the documentation and its test, which would also make [the samples](../chat-pane/samples.md) verified by existing rather than by review. It cannot be published casually: a vault with an LLM key configured carries a credential. Two workable answers, and the choice is yours: a `shared`-tier key with hard `maxCostPerSession` and `maxCallsPerSession` caps chosen deliberately for publication, or bring-your-own-key following the Article 9 Lab precedent | Blocks the demo vault, and with it the strongest thing this site could add next | waiting on human | | N7 | **Confirm the network boundary with `sgit.ai`** (pack Q2). Proposed and published unconfirmed: this site owns the **capability**, `sgit.ai` owns the **product tour**. [On the network page](../network/index.md).

Anything added under "Needed from the project lead" with an answer gets actioned next session. - **Agent to human:** every release updates this page and [versions](versions.md); requests appear in the N-table above, most-blocking first. - **Decisions log:** the pipeline shipped before the content, so every release goes through a gate that already works. The API reference is generated rather than written, so this site cannot become the second source of truth the corpus refused to create. The website half is labelled thin rather than levelled with the vault half. The injection page is held rather than written to a question that has no ruling. And the brief's conditions were made into build gates rather than left as intentions. [← How this site is built](index.md) [Release history →](versions.md) ============================================================================== /admin/versions.md ============================================================================== # Release history · llms.sgit.ai *Source: · site v0.2.0 · the markdown twin of this page, generated from it.* --- [llms.sgit.ai](../index.md) / admin / versions # Release history Every push to `dev` is a release: CI validates the site, verifies the version bump, tags the commit `v{release}.{major}.{minor}`, and deploys to GitHub Pages. The version is owned by `admin/build/version.txt` and must agree with the release commit's subject. | Version | Date | What shipped | |---|---|---| | v0.2.0 | 25 Aug 2026 | **The site, built from the brief pack.** The pack arrived (twelve documents, a 24-row source manifest, v0.33.62) and the site was built in the build order it sets: [the chat pane](../chat-pane/index.md) with its three surfaces and the honesty mechanisms published as decisions-with-reasons, [eight runnable samples](../chat-pane/samples.md), [the `sg.llm.*` reference](../api/index.md) and [the traps](../api/traps.md), [the security model with its gap stated unsoftened](../security/index.md), [the website half labelled as thin](../websites/index.md), [provenance](../provenance/index.md), [the provider layer](../openrouter/index.md), [local models](../local/index.md), [the agent surface](../agents/index.md) and [what is shipped and what is not](../shipped/index.md). The pack itself is [published verbatim](../documents/index.md) with a generated reader page per document. **Q1 answered by mechanism rather than convention.** The complete `sg.llm.*` contract existed only inside a 9,487-word agent authoring file, and the corpus had refused to copy it on the grounds that a competing document would drift. So the section is vendored under `sources/` with its SHA-256 recorded and [the reference is generated from it](../api/index.md); gate 6 fails the build if the page stops matching. Readable to a human, and still one author. **The agent surface treated as an acceptance criterion.** A markdown twin at every path with links rewritten to point at twins, a self-sufficient `llms.txt`, an [llms-full.txt](../llms-full.txt) that the site this pattern came from does not have, and a sitemap generated from the tree listing both. Gates 7 to 9 enforce all of it, because "it can read the map and cannot walk it" is this site's inherited finding rather than an outside one. **Seven claims re-verified against the shipped source** at v0.33.62 rather than against the brief, per the pack's own closing instruction: five confirmed, one superseded and one no longer true. [The injection question has moved](../security/index.md#injection) (a `BEGIN/END UNTRUSTED DATA` fence ships, with deny-by-default tool grants the model cannot reach), published as a narrowing rather than an answer, with the `/injection/` page still held. And [the contract and the code now disagree about tool calling](../shipped/index.md#drift), reported as N5. The gate grew from five checks to eleven, most of them the brief's own conditions made executable: key shapes banned before the first sample page shipped, the CSP qualification required on the front page, twins required and required to be current, house spelling enforced. | | v0.1.1 | 25 Aug 2026 | **The pipeline, verified on a live deploy — and the request it answers, corrected.** The first release ran green end to end: the gate passed, CI tagged the release commit `v0.1.0`, and the deploy published. [llms.sgit.ai](https://llms.sgit.ai) already resolves and serves, and the `github.io` address redirects to it, so [N2](comms.md#needs) — which this site opened asking for DNS — was answered before it was asked and is closed as done. This release is also the second half of the proof: it exercises the tag job's next-minor check, which the first release could not, because there was no previous tag to be next after. | | v0.1.0 | 25 Aug 2026 | **The CI pipeline, auto-tagging, and the front page it gates.** Ports the house pattern from [pki.sgit.ai](https://pki.sgit.ai) — validate → tag → deploy, where a validation failure stops the release entirely — with two improvements carried from the newer sibling sites: the tag job anchors on the newest release commit reachable from `HEAD` rather than `HEAD` itself, so a pull request landing as a merge commit does not stop the release, and the backfill checks the remote before pushing rather than re-pushing every existing tag on every run. The gate (`admin/build/validate.js`) carries five checks: version agreement across every page badge, the history table, `llms.txt` and `index.md`; internal links resolve, with query strings stripped as well as fragments; every page declares a canonical URL on the host in `CNAME`; every `` in the sitemap is on that host and has a file behind it; and a key-leak tripwire that bans both a vault-key-shaped string and key material following the write-key prefix. Nav and footer come from a single definition in `admin/build/chrome.py`, applied across the tree, so the version badge CI enforces cannot drift as the site grows. **The front page carries no argument, and says so.** The brief that sets this site's thesis has not arrived — [N1 on the comms page](comms.md#needs) — so rather than filling the space with material that would be deleted on its arrival, this release publishes the mechanism and the request. One fix reported upstream: the sibling `standards.sgit.ai` repository ignores `admin/build/` through the inherited Python `.gitignore`, so its own gate script is not committed; this repository carries the negation that fixes it. | [← How this site is built](index.md) [Comms →](comms.md) ============================================================================== THE BRIEF PACK THIS SITE WAS BUILT FROM ============================================================================== Published verbatim under /briefs/. CC BY 4.0, Dinis Cruz. ============================================================================== /briefs/00__BRIEF.md ============================================================================== # 00 — The Brief: `llms.sgit.ai` **Version** v0.33.62 · 24 August 2026 **From** Dinis Cruz, via the SG/Send Librarian **To** the agent commissioned to build `llms.sgit.ai` **Licence** CC BY 4.0 --- ## 1. The commission > *"focused on my work about LLMs, which should include **the work and code samples of how to add an LLM chat pane to websites and vaults** (this will be `llms.sgit.ai`)."* The chat-pane half is the strongest thing here and it is **already built, already documented, and already shipping** — but the documentation lives in an agent authoring contract that no human reader will ever find. The wider LLM work is broad and scattered. --- ## 2. The headline: there are three chat-pane surfaces, not one This is the thing to get right on page one, because they differ in **who holds the key** and **who needs permission** — and most people assume there is only one. | Surface | Where | App involvement | Permission needed | |---|---|---|---| | **1. The vault chat panel** | `/vault` → **✨ AI Chat** | none | **none** | | **2. The same panel, beside a running app** | `/en-gb/app/` → **✨ AI** | **none** | **none** | | **3. AI inside your own app** | your vault app's UI | you build it | **`permissions.llm.chat`** | Surfaces 1 and 2 are **no-code**. The panel runs on **host chrome at the real origin**, so it holds the vault key and the microphone directly; the sandboxed app frame sees neither and cannot read the conversation. > ***"Every existing vault app gets this without being changed."*** Surface 3 is the one that needs code, and it is the one the commission asked for samples of. `01__` covers all three; `02__` is the API; **`code__chat-pane-samples.md` ships runnable samples.** --- ## 3. The idea worth leading with > **Your app calls a language model without ever holding an API key.** The key lives in `.vault/llm/config.json`, **inside the permission floor** — the app cannot read it. The host makes the call. You send messages and receive text. That single sentence is the site's thesis, and it is unusual enough to be the front page. Everything else — the grants, the consent HUD, the budget caps, the streaming contract, the cost ledger — follows from deciding that **the credential and the code that spends it should not be in the same trust boundary**. --- ## 4. What is actually shipped Verbatim from the 2 August capability brief: > **Shipped:** the shared engine (`SGLlm`), vault key/policy resolution (`SGLlmVault`), the admin settings panel, the host-native chat panel (multi-file, params, ledger, **voice**, **pasted screenshots**) on **both** `/vault` and `/en-gb/app/`, and the `sg.llm.*` bridge with permission + consent + budget + streaming + cancel + `listen` + `imagePart`. That is a lot, and it is unusually complete for something with no public documentation. --- ## 5. ⚠️ The honesty constraint — and one item on it is load-bearing The same brief's **Not built** list, and the first item is not a nice-to-have: > **CSP egress lockdown.** *App frames are not yet served with a `connect-src` that blocks direct network access, so a malicious app could still call an LLM provider itself with its own key.* **"The bridge protects *your* key; it is not yet a boundary that prevents all egress. This is the gap that turns the current design from a convenience into a guarantee."** **Publish that sentence.** A site whose thesis is *"your app never holds the key"* must say plainly that the mechanism currently protects the vault's key rather than preventing all egress. It is the difference between a convenience and a guarantee, the corpus says so itself, and a reader will find it either way. Also not built: - **Phase 4 minted credentials** — short-lived, budget-capped tokens so the vault holds a *reference*, not a key. Described as *"the commercially load-bearing piece"*, and the thing that would make vault-sharing safe with AI configured. - **ViV kernel parity** — nested vault-in-vault kernels do not relay `sg.llm.*` yet. - **A per-vault audio model setting** — the transcription model is a constant. And the standing warning from Part 1 of the how-to, which belongs on every page about configuration: > *"**Know what you are storing.** With a key configured, the vault contains a credential. Sharing the vault key shares the ability to spend it."* --- ## 6. The wider LLM work — broad, and unevenly developed Beyond the chat pane, measured across the corpus: | Thread | Files | State | |---|---:|---| | **Provenance / determinism** | 431 mention provenance, 421 determinism | **The oldest thread** — the earliest dated artefact in the whole estate is *Deterministic GenAI Outputs with Provenance*, OWASP AppSec Lisbon, 28 June 2024 | | **RAG and graph grounding** | 2,095 | Pervasive, and mostly *about* graphs rather than about retrieval | | **Prompt injection** | 92 | Real, concentrated in the agent-to-agent and sentinel clusters | | **OpenRouter as the provider layer** | 442 | The estate's actual model access path — BYOK, model globs, generation-id reconciliation | | **Local LLMs / Ollama** | 144 | Offline chat, the Docker dev environment, and two sg-compute specs (`ollama`, `local_claude`) | | **Structured output** | 41 | Underdeveloped relative to how much the estate depends on it | | **Hallucination** | 45 | Mostly framed as a grounding problem, not a model problem | | **Cost per token / model routing** | 2 / 1 | **Almost nothing written**, despite the ledger being built | **The shape to publish:** this estate's LLM position is not about models. It is about **provenance, grounding, and keeping the credential away from the code** — and that has been consistent since June 2024. --- ## 7. The numbers | | | |---|---| | **The API** | `sg.llm.available` · `chat` · `cancel` · `usage` · `models` · `imagePart` · `listen` · `listenStop` · `listenCancel` · `listening` | | **Grants** | `chat` · `models` · `usage` · `listen` — **default-deny**, and `listen` is never implied by `chat` | | **Error codes** | 9 — `EPERM` `ECONSENT` `ENOKEY` `EREADONLY` `EBUDGET` `EMODEL` `EABORT` `EIMGSIZE` `EPROTO` | | **Chat panel** | 24,000-char shared file budget · streaming coalesced on a ~50 ms timer · CSV/JSON ledger export with OpenRouter generation ids | | **Images** | png/jpeg/webp/gif · downscaled to 1568px · **base64 chunked at 8190, not 8192** | | **Voice** | host-held microphone · `google/gemini-3.5-flash` by default · consent every time | | **Canonical docs** | `AUTHORING.md` §"Calling an LLM" · the `create-vault-apps` skill · the 2 Aug how-to brief | | **This pack** | 9 documents + a runnable code-samples file · manifest of 24 rows | --- ## 8. Build order 1. **`/chat-pane/`** — the three surfaces, the decision table, and the samples. **This is the commission.** `01__` + `code__chat-pane-samples.md`. 2. **`/api/`** — the full `sg.llm.*` reference. `02__`. It exists today only inside a 9,487-word agent authoring contract; extracting it is the single highest-value publishing act available. 3. **`/security/`** — the key-never-in-the-frame model, the grant ladder, consent, budgets, **and the CSP gap stated plainly**. `03__`. 4. **`/websites/`** — what changes when there is no vault. `04__`. **This is the half of the commission with the least existing material** — see `08__` G1. 5. **`/provenance/`** — the oldest and most distinctive thread, from the 2024 OWASP talk forward. `05__`. 6. **`/local/`** — Ollama, the offline Docker chat, and the two sg-compute specs. 7. **`/shipped/`** — §5, unsoftened, with the CSP sentence quoted. Publish the build order unresolved with `08__`'s open questions and tensions visible. --- This document is released under the Creative Commons Attribution 4.0 International licence (CC BY 4.0). ============================================================================== /briefs/00__pack-readme.md ============================================================================== # llms.sgit.ai — brief pack **For:** the agent commissioned to build `llms.sgit.ai` **From:** Dinis Cruz, via the SG/Send Librarian **Version:** v0.33.62 · 24 August 2026 **Licence:** CC BY 4.0 — see `LICENSE.md`, which carries a key-handling rule specific to this site. --- ## What this is Your LLM work, and specifically **how to add an LLM chat pane to websites and vaults**, with code samples. The vault half is **shipped, complete, and documented in a place no human reader will find.** The website half is thin. The pack says which is which rather than levelling them. --- ## The thesis > **Your app calls a language model without ever holding an API key.** The key lives in `.vault/llm/config.json`, inside the permission floor — the app cannot read it.

The best documentation is the hardest to find.** The complete `sg.llm.*` contract exists **only** inside `library/guides/vault-html/AUTHORING.md` — a 9,487-word agent authoring document. It is genuinely excellent (the 8190 base64 explanation, the greenlet reasoning, the labelled-cost rule) and no human reader will ever open it. **Extracting it is the single highest-value publishing act on this site** — but generate it, don't hand-copy: the corpus explicitly refused to create a competing reference *"that drifts."* **2. The honesty mechanisms are the best work and are published nowhere.** One 24,000-char budget shared across all attached files, not one each. `TRUNCATED` written into the text **the model sees**, *"so it cannot pretend to have read the whole thing."* Estimated costs rendered with `~` and **never as a bill**. Pasted images cleared after one send, because *"an image left attached would silently re-send and re-bill on every turn."* Recording stated in words — *"● Recording — your microphone is on"* — *"not left to an icon."* **Publish them as decisions with reasons.** That page is more persuasive than any feature tour. **3. The website half is a gap, not an asset.** No component, no documented pattern, no code. `04__` compares three options — backend proxy, BYOK-in-browser (there's a precedent in the Article 9 Lab), or embed the vault surface — and recommends shipping a `sg-llm-chat` web component with a pluggable transport, built to the estate's own component conventions. **4. One question has no answer and it matters.** The chat panel attaches vault file contents to the model's context. Those files are untrusted. **What stops one that says "ignore previous instructions" from doing so?** The budget and the `TRUNCATED` marker are honesty mechanisms, not injection defences. `08__` Q3 — **do not publish an injection page until this is answered.** --- ## The artefact this site should ship **A vault app that is the documentation** (`06__` §4). One app exercising `available`, `chat`, streaming, `cancel`, `usage`, `models`, `imagePart` and `listen` — published as both the demo and the test, so the samples are verified by existing rather than by review. ⚠️ With one condition: a vault with an LLM key configured **carries a credential**. Either give the demo a `shared`-tier key with hard spend caps chosen deliberately for publication, or ask the visitor for their own key. **Decide before publishing, not after.** --- ## House pattern Copy `pki.sgit.ai`, add the `/llms-full.txt` it lacks — and note the obligation this site carries that no sibling does: **a site called `llms.sgit.ai` will be read by more agents than any page in the estate.** Your own agent-access report's finding, *"it can read the map and cannot walk it"*, is an acceptance criterion here, not a topic. --- This file is released under the Creative Commons Attribution 4.0 International licence (CC BY 4.0). ============================================================================== /briefs/01__the-chat-pane.md ============================================================================== # 01 — The chat pane: three surfaces The commission asked for *"the work and code samples of how to add an LLM chat pane to websites and vaults."* This document is the decision layer — **which of three surfaces you want**. `code__chat-pane-samples.md` is the code. --- ## 1. The decision table | | **1. Vault chat panel** | **2. Beside a running app** | **3. Inside your app** | |---|---|---|---| | **Where** | `/vault` → ✨ AI Chat | `/en-gb/app/` → ✨ AI | your app's own UI | | **Code required** | **none** | **none** | yes — `02__` | | **Permission required** | **none** | **none** | `permissions.llm.chat` | | **Who holds the key** | host, at the real origin | host, at the real origin | host — **never your frame** | | **Who holds the microphone** | host | host | host, via `sg.llm.listen()` | | **Can the app read the conversation?** | n/a | **no** | it *is* the app | | **Works on existing apps unchanged** | n/a | **yes** | no | | **Use when** | you want to chat about vault files | you want AI beside an app you did not write | AI is part of what your app *does* | **Start at the top and stop as soon as one fits.** Surfaces 1 and 2 cost nothing to adopt and carry no attack surface of your own. Surface 3 is for when the model is part of the product, not a companion to it. --- ## 2. Surface 1 — the vault chat panel Open it from **✨ AI Chat** in the vault header, or **➕ Add to chat** on any file. Nothing to build. What it does, and each of these is a design decision worth publishing: - **Attach several files.** Each shows as a chip with a `×`. **Re-adding a file replaces its contents**, so it refreshes after an edit rather than duplicating. - **Files share one 24,000-character budget** — *"not one each, so attaching a second file cannot silently double your prompt or your bill."* Trimmed files say `TRUNCATED` **in the text the model sees**, *"so it cannot pretend to have read the whole thing."* - **⚙ request params** — temperature, top-p, max tokens. Blank means the provider's default. **Max tokens is clamped to the vault policy, and says so when it clamps.** - **🧾 AI Requests** — every call with its **OpenRouter generation id**, tokens, cost, latency and the files it referenced; running totals; CSV/JSON export. **Billed and estimated costs are shown separately** — *"an estimate is never rendered as a bill."* - **🖼 paste a screenshot** — attaches as a thumbnail and goes with your **next message only, then clears**: *"unlike a file, an image left attached would silently re-send and re-bill on every turn."* Downscaled to 1568px. **If the picked model cannot read images the panel says so on attach, names it, and suggests ones that can.** - **🎤 voice** — tap the mic, speak, tap ■. Recording is stated **in words** — *"● Recording — your microphone is on"* — *"not left to an icon."* **Cancel releases the device, not just the bar.** Transcription uses an audio-capable model (`google/gemini-3.5-flash` by default), *"not your chat model, which almost certainly cannot hear."* - **Panels are ordinary `sg-layout` panes** — drag, resize, close. Closing **parks** them: transcript, attached files and cost pills survive reopening. **Every one of those bullets is a small honesty mechanism**, and collectively they are the strongest argument the site can make. `TRUNCATED` in the model's own text, one shared budget rather than one per file, estimates never shown as bills, images that clear after one turn, recording announced in words. **Publish them as a list of decisions with their reasons** — that page is more persuasive than any feature tour. --- ## 3. Surface 2 — the same panel, beside a running app Open a vault app at `/en-gb/app/#` and there is a **✨ AI** button in the HUD, next to *Open Vault*. Identical chat and requests panels, beside the app. > ***"The app is not involved.** The panel runs on host chrome at the real origin, so it holds the vault key and the microphone directly; the sandboxed app frame sees neither, cannot read the conversation, and needs no `permissions.llm.*`. **Every existing vault app gets this without being changed.**"* App authors get a **preference, not authority**: ```json { "hud": { "show": { "llm": false } } } ``` `false` hides the button if a chat control would clash with their own UI; `true` forces it on in `minimal` mode, where it is off by default. *"That is a preference about chrome, not authority: it does not affect what the app itself may do."* **This surface is the best-value thing on the whole site** — every existing app gets an AI panel for one config line or none — and it is currently documented in exactly one debrief. --- ## 4. Surface 3 — AI inside your app This is the one that needs code and grants. Three steps, and step 2 is the one people skip. **1. Declare the grants** in `app.json` — default-deny, like every other capability: ```json { "entry": "index.html", "permissions": { "llm": { "chat": true, "models": true, "usage": true } } } ``` *"`chat` is the one that spends money; `models` and `usage` are read-only. Grant only what you use."* **2. Check availability BEFORE you render a chat UI.** > *"`sg.llm.available()` is **not optional politeness**. Unlike other namespaces, LLM access depends on *runtime* state: whether the vault has a key configured, whether this is a read-only session, whether the budget is spent. **Ask first, then decide what to draw.**"* ```js const a = await sg.llm.available(); if (!a.ok) { showFallbackUI(a.reason); return; } // ENOKEY | EPERM | EREADONLY console.log('ready:', a.model, 'remaining:', a.remaining); ``` **3. Chat.** Full samples in `code__chat-pane-samples.md`; the API in `02__`. --- ## 5. Turning it on for a vault (once) Before any surface works, the vault needs a key: 1. Open the vault with its **full key** — *"an owner-sealed key cannot be unsealed in a read-only session — **that is cryptographic, not a policy check**."* 2. **Settings → AI models (OpenRouter)** → paste an OpenRouter key → **Test** → **Save**. 3. Optional: default model, an allowed-models list as **globs** (`anthropic/*`), and spend caps (`maxCostPerSession`, `maxCallsPerSession`, `maxTokensPerCall`). **Two key tiers, and the choice matters:** | Tier | Behaviour | |---|---| | **`owner`** (default) | Sealed with the vault's **write** key. A read-only opener gets `EREADONLY` and cannot use it | | **`shared`** | Readable by anyone who can open the vault | > *"Prefer `owner` unless you deliberately want every opener to be able to spend."* And the warning that belongs on every configuration page: > *"**Know what you are storing.** With a key configured, the vault contains a credential. Sharing the vault key shares the ability to spend it. Short-lived minted credentials are planned (Phase 4) and would remove this; **until then, treat such a vault as carrying a secret.**"* --- ## 6. Model defaults — a bug worth publishing From the status section, and it is a good story: > *"With no `models.default` configured the panel auto-picks, and it now tries named models first (`anthropic/claude-sonnet-5`, then opus-5, sonnet-4, gemini-3.5-flash, gpt-5). **It used to match only on the vendor prefix against an alphabetically sorted list, which picked `anthropic/claude-3-haiku` — the oldest model on the key, and not a vision model.**"* Alphabetical order picked the worst available model, silently, and the symptom would have looked like *"the AI is bad"* rather than *"the default is wrong."* An explicit `models.default` and the `models.allow` list still win. **Publish it under a "defaults are a design decision" heading.** It is exactly the kind of thing the site should teach. --- ## 7. What to build first 1. **The decision table** (§1) as the landing page. Most readers will discover they need no code at all, which is the right outcome. 2. **Surface 2's one-line HUD config**, because *"every existing vault app gets this without being changed"* is the single highest-value sentence in the corpus and it is buried in a debrief. 3. **The honesty-mechanism list** (§2), as decisions-with-reasons rather than features. 4. **Then the code** — `02__` and the samples. --- This document is released under the Creative Commons Attribution 4.0 International licence (CC BY 4.0). ============================================================================== /briefs/02__the-sg-llm-api.md ============================================================================== # 02 — The `sg.llm.*` API The complete reference currently exists **only inside `library/guides/vault-html/AUTHORING.md`**, a 9,487-word agent authoring contract. Extracting it into a readable public reference is the single highest-value publishing act on this site. Shipped **2 August 2026**; `listen` and `imagePart` added **3 August 2026**. --- ## 1. The surface | Call | Grant | Returns | |---|---|---| | `sg.llm.available()` | — | `{ok, reason, model, remaining:{calls,cost}}` | | `sg.llm.chat(req, onToken?)` | `chat` | `{content, usage, cost, id}` · promise carries `.requestId` | | `sg.llm.cancel(requestId)` | — | aborts an in-flight call | | `sg.llm.models()` | `models` | the vault's **already-filtered** allow-list | | `sg.llm.usage()` | `usage` | `{calls, cost, remaining}` for the **whole session** | | `sg.llm.imagePart(blobOrBytes)` | — | a content part for a multimodal message | | `sg.llm.listen(opts?)` | `listen` | `{text, durationMs, bytes, format, cost}` | | `sg.llm.listenStop()` / `listenCancel()` / `listening()` | `listen` | recording control and state | **Request fields:** `messages` (required), plus optional `model`, `maxTokens`, `temperature`, `topP`, `stream: false`. --- ## 2. The three streaming properties to rely on These are contract guarantees, not implementation details, and they are what let you write a chat UI without defensive code: 1. **The terminal reply is authoritative.** *"An app that ignores `onToken` entirely still gets the complete `content`. **Deltas are a UX affordance, never the source of truth.**"* 2. **Deltas carry only the increment** (`delta`), plus a running `acc` for convenience. *"The host coalesces them on a ~50 ms timer, so you get readable chunks rather than a postMessage per token."* 3. **`cost` is labelled** — `{value, source, estimated}`. *"`estimated: true` means it was computed from token counts × list price, not billed. **Render estimates with a `~`. Never show one as a bill.**"* That third one is a house rule with teeth, and it should appear on the site as a rule rather than a note. --- ## 3. Error codes — branch on `err.code` | Code | Meaning | |---|---| | `EPERM` | no grant | | `ECONSENT` | user declined | | `ENOKEY` | no key configured for this vault | | `EREADONLY` | owner-sealed key, read-only session | | `EBUDGET` | cap reached | | `EMODEL` | model not allow-listed, none selected, or **it cannot read the image/audio you sent** | | `EABORT` | cancelled | | `EIMGSIZE` | image payload over the host ceiling | | `EPROTO` | upstream failure | > *"They arrive as `err.code`, so **branch on that rather than on message text.**"* **`EMODEL` names the model.** *"A model that cannot see gets you `EMODEL` naming the model, instead of a provider error that names nothing."* That is a deliberate error-design choice and worth publishing as one. --- ## 4. Images ```js const part = await sg.llm.imagePart(blobOrBytes); // or a data: URL you already have const res = await sg.llm.chat({ messages: [{ role: 'user', content: [ { type: 'text', text: 'What is wrong in this screenshot?' }, part ] }] }); ``` **Three things the site must carry, because each is a real trap:** **(a) The 8190 bug — publish this verbatim.** > *"Use `sg.llm.imagePart()` rather than encoding it yourself. It runs in your frame (no host round trip — the bytes are already yours) and **chunks base64 at 8190, not 8192**. `8192 % 3 === 2`, so a 8192-sized chunk emits `=` padding mid-string and `atob()` rejects it; **this codebase has shipped that exact bug three times.**"* A three-times-shipped bug with the arithmetic explained is the best kind of documentation. **(b) Vision capability is read from the live catalogue, not a hard-coded list** — *"so a new vision model works the day it ships."* And: *"note that `text->image` is an image **generator**, not a reader — it is correctly refused."* **(c) Not a new grant.** *"An image is an ordinary `chat()` call under `permissions.llm.chat`."* And the size ceiling is the host's: *"That ceiling is not yours to raise: **it is spending the vault's key.**"* Accepted types: **png, jpeg, webp, gif**. *"Not svg — it is a scriptable document, not a bitmap, and no provider takes it."* Images appear in the ledger **as their own count, never folded into the character total** — *"`sg.llm.usage()` and the AI Requests pane both stay honest about what the expensive calls were."* --- ## 5. Voice ```json { "permissions": { "llm": { "chat": true, "listen": true } } } ``` ```js micBtn.onclick = async () => { try { const { text } = await sg.llm.listen(); // opts: {maxMs, model, prompt} input.value = text; } catch (e) { if (e.code === 'ECONSENT') return; // user declined — not an error worth showing if (e.code === 'ENOMIC') showTypeInstead(); } }; ``` **Two design decisions to publish:** > *"**`listen` is a separate grant and is never implied by `chat`.** Recording a room is a categorically different act from sending text, so an app that can talk to a model does not thereby get a microphone."* It also **asks for consent every time** by default. > *"**Your frame never touches audio.** A sandboxed app frame has no `navigator.mediaDevices` at all, so capture happens in the host — which is also **why the recording indicator is on host chrome where the user can always see it.** You receive `{text, durationMs, bytes, format, cost}` and nothing else; the recording itself never crosses into your frame."* The second is the better argument: the indicator is trustworthy *because* it is not the app's to draw. --- ## 6. What the host does that you do not have to Verbatim, and this table is the API's real value proposition: | Concern | Who handles it | |---|---| | **Holding the API key** | Host. *"It is never in your frame, your bundle, or any message you receive."* | | Which models you may use | Host — `models()` is **already filtered**, so a picker built from it is automatically correct | | Spend caps | Host. `maxCostPerSession` / `maxCallsPerSession` enforced **before** the call; you get `EBUDGET` | | `maxTokens` | Host **clamps** it. *"Asking for more is not an error, it is just capped."* | | Consent | Host. The first `chat()` raises a HUD prompt; declining gives `ECONSENT` | | Whether the model can read an image | Host, from the live catalogue | | Image size ceiling | Host (`EIMGSIZE`) | | Cost reconciliation | Host, **two-source**: the stream's `usage.cost`, then the authoritative `/generation` lookup | **Seven concerns an app does not implement.** That is the page's argument: the bridge is not a convenience wrapper, it is a list of things that would each be got wrong independently by every app that had to do them itself. --- ## 7. `usage()` reports the session, not the surface > *"`usage()` reports the **whole session**, including calls made by the vault UI's own chat panel — **one bill per session, not one per surface.**"* Which means a meter you draw in your app is the *true* total, including the host panel's spending. That is the right default and it is not the obvious one. --- ## 8. How to publish this 1. **Extract it into a real reference page**, per call, with the signature, the grant, the errors and one runnable sample. 2. **Keep `AUTHORING.md` canonical and generate from it**, or you create the second source of truth the corpus explicitly refused to create — see `08__` Q1. 3. **Lead every call with its grant.** Default-deny is the model; the grant is the first thing a reader needs. 4. **Publish the traps as their own page** — the 8190 chunking, `available()` before rendering, images clearing after one turn, estimates never shown as bills, `listen` never implied by `chat`. **That page will be the most-visited on the site.** --- This document is released under the Creative Commons Attribution 4.0 International licence (CC BY 4.0). ============================================================================== /briefs/03__the-security-model.md ============================================================================== # 03 — The security model, and the gap in it The thesis is *"your app calls a model without ever holding an API key."* This document is how that works, and — in §5 — the one place it currently stops short of a guarantee. --- ## 1. Where the key lives `.vault/llm/config.json`, **inside the permission floor**. The app cannot read it. The host makes every call. > *"Holding the API key | **Host.** It is never in your frame, your bundle, or any message you receive."* **Two tiers, and the difference is cryptographic rather than a policy check:** | Tier | Behaviour | |---|---| | **`owner`** (default) | Sealed with the vault's **write** key. A read-only opener gets `EREADONLY` — *"an owner-sealed key cannot be unsealed in a read-only session — that is cryptographic, not a policy check"* | | **`shared`** | Readable by anyone who can open the vault | > *"Prefer `owner` unless you deliberately want every opener to be able to spend."* --- ## 2. The four-layer ladder Every call passes four independent checks, and each one fails with its own code: | Layer | Mechanism | Failure | |---|---|---| | **1. Grant** | `permissions.llm.*` in `app.json`, **default-deny** | `EPERM` | | **2. Consent** | the first `chat()` raises a HUD prompt the user must accept | `ECONSENT` | | **3. Budget** | `maxCostPerSession` / `maxCallsPerSession`, enforced **before** the call | `EBUDGET` | | **4. Policy** | model allow-list (globs); `maxTokens` **clamped**, not rejected | `EMODEL` | **Grant, consent, budget, policy.** A developer decision, a user decision, a spend decision and an owner decision — four different people can each say no, and the failure tells you which one did. **The grants are deliberately narrow:** `chat` spends money; `models` and `usage` are read-only; **`listen` is never implied by `chat`.** > *"Recording a room is a categorically different act from sending text, so an app that can talk to a model does not thereby get a microphone."* --- ## 3. What the frame cannot reach The sandboxed app frame has **no `navigator.mediaDevices` at all**. Audio capture happens in the host — which is also why the recording indicator lives on host chrome: > *"**the recording indicator is on host chrome where the user can always see it.** You receive `{text, durationMs, bytes, format, cost}` and nothing else; the recording itself never crosses into your frame."* **An indicator the app cannot draw is an indicator the app cannot fake.** That is the strongest security argument in the whole design and it should be stated in exactly those terms. Same principle on surfaces 1 and 2 (`01__`): the chat panel runs on host chrome at the real origin, so the app frame *"sees neither, cannot read the conversation, and needs no `permissions.llm.*`."* --- ## 4. Cost integrity Three mechanisms, and they are honesty features rather than security ones — but they belong here because they are all about not being able to mislead: - **Two-source reconciliation.** *"Host, two-source (stream `usage.cost`, then the authoritative `/generation` lookup)."* - **Estimates are labelled and must be rendered as estimates.** `{value, source, estimated}` — *"Render estimates with a `~`. **Never show one as a bill.**"* - **Images are counted separately**, never folded into the character total, *"so `sg.llm.usage()` and the AI Requests pane both stay honest about what the expensive calls were."* And `usage()` reports the **whole session** including the host panel's own calls — *"one bill per session, not one per surface."* --- ## 5. ⚠️ The gap — publish this sentence From the 2 August capability brief's *Not built* section: > **CSP egress lockdown.** *"App frames are not yet served with a `connect-src` that blocks direct network access, so a malicious app could still call an LLM provider itself with its own key. **The bridge protects *your* key; it is not yet a boundary that prevents all egress. This is the gap that turns the current design from a convenience into a guarantee.**"* **Read precisely what that does and does not say.** - ✅ The vault's key is genuinely protected. It never enters the frame. - ✅ Spend against the vault's key is genuinely capped, consented and logged. - ❌ A malicious app can still reach the network with **its own** credential, so the bridge is **not** an egress boundary. **The honest framing for the site:** the model here is *"we protect the credential you trusted us with"*, not *"nothing leaves this frame."* Those are different claims and only the first is currently true. **Do not soften it, and do not bury it.** A site whose front page says *"your app never holds the key"* must carry the qualification within one click, because the corpus states it plainly and any reader who finds the brief first will trust the site less for having omitted it. The named fix is **Phase 4 minted credentials** — *"short-lived, budget-capped tokens from SG-API so the vault holds a **reference**, not a key."* Described as *"what would make vault-sharing safe with AI configured, and… the commercially load-bearing piece."* --- ## 6. The standing warning about configured vaults > *"**Know what you are storing.** With a key configured, the vault contains a credential. **Sharing the vault key shares the ability to spend it.** Short-lived minted credentials are planned (Phase 4) and would remove this; until then, **treat such a vault as carrying a secret.**"* This connects directly to the estate's read-key/write-key doctrine (`standards.sgit.ai` `03__`, `open-source.sgit.ai` `02__` §6): **a vault with an LLM key configured is a vault whose sharing calculus has changed.** Publishing a read key for such a vault is not the same act as publishing one for a plain vault, and the site should say so beside the key-tier table in `01__` §5. --- ## 7. Two other gaps worth naming **ViV kernel parity.** *"`sg.llm.*` is served by the `/en-gb/app/` host. Nested vault-in-vault kernels (`kernel-app-handlers.js`) do not relay it yet."* So an app running inside a nested vault silently has no LLM bridge. **No per-vault audio model setting.** The transcription model is a constant (`google/gemini-3.5-flash`). Fine as a default; not configurable when it should be, since the chat model and the audio model are necessarily different and only one of them is a setting. --- ## 8. What the security page should say 1. **Lead with the ladder** (§2) — grant, consent, budget, policy — because it explains all nine error codes in one table. 2. **Make §3's argument explicitly**: the microphone indicator is trustworthy *because the app cannot draw it*. 3. **State the CSP gap in the same breath as the thesis**, not in a footnote. 4. **Put the "know what you are storing" warning next to the setup instructions**, where the decision is actually made. 5. **Name Phase 4** as the fix, and be clear it is not shipped. --- This document is released under the Creative Commons Attribution 4.0 International licence (CC BY 4.0). ============================================================================== /briefs/04__websites-vs-vaults.md ============================================================================== # 04 — Websites vs vaults: what changes when there is no host The commission asked for chat panes on **websites and vaults**. The vault story is complete, shipped and documented (`01__`–`03__`). **The website story is the thinner half, and the site should be honest about that** — it is a gap to fill, not an existing asset to publish. --- ## 1. What a vault gives you that a website does not Everything in `03__` depends on **a host at a different origin from the app**. Take the host away and every guarantee changes: | Mechanism | In a vault | On a plain website | |---|---|---| | **Key storage** | `.vault/llm/config.json`, below the permission floor | **nowhere safe in the browser** | | **Who calls the provider** | the host | your page, or your backend | | **Grant model** | `app.json`, default-deny, enforced by the host | nothing enforces it | | **Consent** | host HUD, outside the app's control | you draw it, so you could fake it | | **Budget caps** | host, before the call | your backend, or nothing | | **Recording indicator** | host chrome — **unfakeable by the app** | your own DOM — fakeable | | **Cost ledger** | host, two-source reconciled | you build it | **The one-line rule:** *the vault bridge exists because the app and the credential are in different trust boundaries. On a plain website they are not, so the same design does not transfer — the question becomes where you put the boundary instead.* --- ## 2. The three options on a website, honestly compared **(a) A backend proxy — the standard answer.** Your server holds the key; the page calls your endpoint. This is the vault model with your own backend playing host. It gets you real key protection, real budget caps and a real ledger — and it costs you a server, an auth story and an abuse-prevention story that the vault host already solved. **(b) Bring-your-own-key in the browser.** The visitor pastes their own key; it stays in their browser. **There is precedent in the estate**: the Regulation Graph vault's Article 9 Lab *"requires a bring-your-own OpenRouter key — deliberately, so no metered capability sits behind the published read key."* That reasoning generalises cleanly to a static site: **a public page cannot carry a spending credential, so the visitor brings their own or there is no chat.** It is honest, it costs nothing to run, and it converts badly. **(c) Embed the vault surface.** Point the reader at a vault that already has the panel. This is the option nobody has written up and it may be the best one for `*.sgit.ai` specifically, since the estate already publishes read keys and already embeds vault content in pages — the embedding mechanism (sandboxed iframe, `postMessage` key handshake, key never in a URL) is built and documented. > ⚠️ **But see `03__` §6**: a vault with an LLM key configured carries a credential, so **publishing a read key for it shares the ability to spend.** Option (c) works only for a vault whose key tier and spend caps were chosen with publication in mind. --- ## 3. What exists today **For websites: almost nothing.** There is no website chat component in the estate, no documented pattern, and no code. What exists that is adjacent: - **The versioned component CDN** (`dev.tools.sgraph.ai`) already serves `sg-vault-client.js` and `sg-vault-write.js` — so **a `sg-llm-chat` component is a natural next member of that family**, and the component conventions are documented (`coding.sgit.ai` `02__`). - **The BYOK precedent** in the Article 9 Lab, with its reasoning stated. - **The offline Ollama chat UI** (18 March 2026) — a FastAPI proxy to a local Ollama, built on the `sg-layout` web component, for *"offline LLM chat during travel."* Small, and it is a real worked example of a chat UI against a proxy endpoint, which is option (a) in miniature. **Recommendation:** `/websites/` should present the three options with this honesty, recommend **(a) for products and (c) for `*.sgit.ai` pages**, and ship **a `sg-llm-chat` web component** as the concrete artefact — built to the estate's own component conventions, with a pluggable transport so the same component serves all three options. `08__` G1. --- ## 4. The one thing that transfers unchanged **The honesty mechanisms.** None of them depend on a host: - one shared context budget, never one per file - `TRUNCATED` in the text the model sees - estimates rendered with `~`, never as a bill - images cleared after one send - `available()` before rendering - branch on error codes, not message text - recording announced in words **Those are the transferable part of this work**, and a website chat pane built without them is worse than a vault one for reasons that have nothing to do with key storage. `code__chat-pane-samples.md` §8 is the checklist; it applies verbatim. --- ## 5. The `llms.txt` connection — the site's other LLM surface There is a second sense in which this estate serves LLMs, and `llms.sgit.ai` is the natural home for it. Every `*.sgit.ai` site publishes `/llms.txt` as its agent surface, and the estate's practice goes further: **the markdown twin at every URL**, extension swapped, with links inside the markdown pointing at markdown, *"so a traversing agent never has to parse HTML."* The mechanism is non-obvious — these are static files, so the rendering happens in a **Lambda@Edge function**. And the finding from the 14 August agent-access report: > *"**The audience is disproportionately agents**… many agents can only fetch URLs that a search engine has already returned to them… **It can read the map and cannot walk it.**"* **That belongs on this site**, because it is the other half of the same subject: `01__`–`03__` are about *putting a model inside your page*, and this is about *making your page readable to a model that arrives from outside*. Cross-link with `coding.sgit.ai` `05__` §5, which has the conventions. --- This document is released under the Creative Commons Attribution 4.0 International licence (CC BY 4.0). ============================================================================== /briefs/05__the-wider-llm-work.md ============================================================================== # 05 — The wider LLM work Beyond the chat pane, the estate's LLM material is broad and unevenly developed. This is what is there, measured, with the threads worth building pages on. --- ## 1. The oldest thread, and the most distinctive: provenance and determinism **The earliest dated artefact in the entire estate** is a talk: *Deterministic GenAI Outputs with Provenance*, **OWASP AppSec Lisbon, 28 June 2024** — 9,879 words of slides and notes, published on `docs.diniscruz.ai` under CC0. Two years later the same instinct runs through everything: **431 files mention provenance, 421 mention determinism.** The chat panel logs an OpenRouter generation id per call. The Regulation Graph vault carries a SHA-256 of the retrieved bytes on every node. The grounding ladder terminates a claim at a measure. **This is the site's spine, and it predates the products.** The position is not *"models are unreliable, use a better one"* — it is *"a model output is only usable when you can say where it came from."* Everything else on this site is a mechanism serving that. --- ## 2. Grounding, not prompting `hallucin*` appears in only 45 files — and where it does, it is framed as a **grounding** problem rather than a model problem. The estate's answer is the grounding ladder: ``` Risk := a downward path to a Vulnerability AND an upward path toward a top risk Vulnerability := a Fact (grounded below) AND an upward path to a Risk Fact := a downward path to Evidence Evidence := a downward path to a Measure Measure := an observation of the node it measures, grounded on a Twin ``` And the anti-fabrication argument that follows: **a model asked to assess something will produce a plausible answer; a model asked to attach a finding to a provision hash, and to a measure, and to a twin, either finds the path or reports that it cannot.** ⚠️ **The ladder belongs to `risks.sgit.ai` and `standards.sgit.ai`.** This site should state it in three lines and link out — it is the *reason* the LLM work looks the way it does, not this site's subject. `07__` §5. --- ## 3. OpenRouter as the provider layer **442 files mention it.** It is the estate's actual model-access path, and several design consequences follow that are worth a page: - **BYOK per vault** — the key is the vault owner's, not a platform key. - **Model allow-lists as globs** — `anthropic/*` in `models.allow`. - **Generation ids as the reconciliation handle** — the ledger stores them, and cost is reconciled two-source (stream, then the authoritative `/generation` lookup). - **Capability read from the live catalogue**, not a hard-coded list, *"so a new vision model works the day it ships."* - **The default-picker bug** (`01__` §6) — alphabetical vendor-prefix matching silently selected the oldest model on the key. **Nobody has written up "why route through a provider aggregator"**, and it is a real position with real trade-offs: one key for many models, capability metadata for free, and a single point of dependency between you and every model you use. --- ## 4. Local and offline **144 files mention Ollama**, and there are three concrete artefacts: - **The offline Docker chat** (18 March 2026) — a chat UI plus a FastAPI proxy to a host-native Ollama, with sessions surviving container rebuilds. The stated use case is disarmingly specific: *"Offline LLM chat during travel (flight on 19 March 2026). Must work completely disconnected from the internet once the Docker image is built and Ollama models are pulled."* - **Two sg-compute specs** — `ollama` (939 LOC, `llm-inference`, 120s boot, EXPERIMENTAL) and `local_claude` (1,498 LOC, `llm-inference`, 180s boot, EXPERIMENTAL), each with manifest, CLI, service, schemas and tests. - **A `docker/local-claude/` image** — a local LLM plus Claude Code harness. **The through-line to publish:** the same `/api/chat` proxy shape works against local Ollama and against a remote tunnel, which is why the offline work was never a detour. And it connects to `open-source.sgit.ai`'s sovereignty argument — *"you are one SLA away from losing access"* applies to model providers more sharply than to almost anything else. --- ## 5. Prompt injection and agent security **92 files.** Concentrated in the agent-to-agent communication and SG/Sentinel clusters, and adjacent to a lot of security work that is this estate's home ground. The relevant mechanism already ships in the LLM bridge: **`JS__Expression__Allowlist` is deny-by-default**, and the corresponding rule is documented — *"Evaluate action is allowlist-gated"* — with a CI guard behind it. *"No arbitrary code execution — the shell-server pattern from OSBot-Playwright is not carried forward."* **The unwritten page:** the chat panel attaches vault files to prompts. Those files are untrusted content. **What stops a file that says "ignore previous instructions" from doing so?** The 24,000-character budget and the `TRUNCATED` marker are honesty mechanisms, not injection defences. `08__` Q3 — and it is the most important open question on the site. --- ## 6. What is thin | Topic | Files | Note | |---|---:|---| | **Structured output** | 41 | Underdeveloped relative to how much the estate depends on models emitting valid schemas. `Type_Safe` validates the result — but nothing documents how the *request* is shaped | | **Evals** | 576 mentions of `eval`, mostly the ordinary word | **No eval suite, no benchmark, no regression test for prompt behaviour anywhere** | | **Cost per token** | **2** | Despite a full ledger being built. The data exists; nobody has analysed it | | **Model routing** | **1** | One mention. No routing logic, no fallback chain, no cost/quality tiering | | **Embeddings** | 100 | Mentioned; no vector store, no retrieval implementation | **Publish this table.** A site about LLM work that lists what it has *not* built is more credible than one that does not, and three of these five are genuinely load-bearing gaps: **evals, structured output and model routing** are the difference between a working integration and an engineered one. --- ## 7. The agent-facing documentation convention Worth its own short page, because it is unusual and it is evidence rather than assertion. The estate writes documentation **explicitly for model readers**, and says so in the filename: ``` library/dependencies/osbot-utils/type_safe/v3.1.1__for_llms__type_safe__testing_guidance.md ^^^^^^^^^ ``` Together with the markdown twin at every URL, `/llms.txt` on every site, and the `llms-full.txt` single-file concatenation, that is a consistent practice: **when a model is a primary reader, write it a document rather than expecting it to parse yours.** Cross-links to `coding.sgit.ai` `05__` §5 (the conventions chosen for agent readers) and `open-source.sgit.ai` `05__` (the argument about who reads code now). --- ## 8. How to sequence these pages 1. **`/provenance/`** — the 2024 talk forward. The spine, and the oldest thing here. 2. **`/openrouter/`** — the provider-layer position, including the default-picker bug. 3. **`/local/`** — Ollama, the offline chat, the two specs, and the sovereignty link. 4. **`/injection/`** — after answering `08__` Q3, not before. Do not publish a page about prompt-injection defences until the file-attachment question has an answer. 5. **`/not-built/`** — §6's table, on `/shipped/`. --- This document is released under the Creative Commons Attribution 4.0 International licence (CC BY 4.0). ============================================================================== /briefs/06__site-architecture.md ============================================================================== # 06 — Site Architecture ## The house pattern, plus one obligation Copy `pki.sgit.ai`; add the `/llms-full.txt` it lacks. And note the obligation this site carries that no sibling does: **a site called `llms.sgit.ai` will be read by more agents than any other page in the estate.** The agent-access report's finding — *"it can read the map and cannot walk it"* — is not a topic here, it is an acceptance criterion. `/llms.txt` must be **self-sufficient** rather than a link list, `/llms-full.txt` must exist, and the markdown twin must work at every path. --- ## Page by page ### `/` — the front page The thesis in one sentence: **"Your app calls a language model without ever holding an API key."** Then, immediately and on the same page, the qualification from `03__` §5 — the bridge protects the vault's key, and is **not yet** an egress boundary. A front page that makes the claim without the caveat is one click from being contradicted by the project's own brief. Then the three-surface decision table, because most readers will discover they need no code at all. ### `/chat-pane/` — **build first** `01__`. The decision table, the three surfaces, the honesty mechanisms as decisions-with-reasons, and the vault setup with its key tiers. **The one sentence to feature: *"Every existing vault app gets this without being changed."*** ### `/chat-pane/samples/` `code__chat-pane-samples.md`, verbatim. Eight samples plus the pre-ship checklist. **These must be runnable and kept runnable** — see §3. ### `/api/` `02__`. The full `sg.llm.*` reference: one page per call with signature, grant, errors and a sample. **And a `/api/traps/` page** — the 8190 chunking, `available()` before rendering, images clearing after one turn, estimates never shown as bills, `listen` never implied by `chat`. That page will be the most visited on the site. ### `/security/` `03__`. The four-layer ladder, the key tiers, the unfakeable recording indicator, cost integrity, **and the CSP gap in full**. Name Phase 4 as the fix and be clear it is not shipped. ### `/websites/` `04__`. The three options, honestly compared, with the recommendation and the `sg-llm-chat` component as the concrete deliverable. **Label this section as the thin half** — it is a gap to fill, not an asset to publish. ### `/provenance/`, `/openrouter/`, `/local/` `05__`. The 2024 OWASP talk forward; the provider-layer position; Ollama and offline. Three pages, in that order. ### `/agents/` The dual surface: the API as machine-readable JSON, **and** the estate's own agent-readability practice — `llms.txt`, the markdown twin, `for_llms` filenames, the Lambda@Edge mechanism. Cross-link `coding.sgit.ai` `05__` §5. ### `/shipped/` `00__` §5 unsoftened — the CSP gap, Phase 4, ViV parity, the audio-model constant — plus `05__` §6's table of what has not been built: **no evals, no structured-output spec, no model routing, no cost analysis despite a full ledger.** ### `/network/`, `/admin/` House pattern. Build order published unresolved with `08__`'s questions and tensions visible. --- ## 3. What must be generated, not written | Content | Source | |---|---| | The API reference | **generated from `AUTHORING.md`** — see `08__` Q1 | | Error-code table | generated from the same | | Code samples | **tested, not just published** — see below | | Corpus counts (442 OpenRouter files, 92 injection, etc.) | generated or dated | | Shipped / not-built | from the capability brief, with its date | **The samples need a test.** A code sample that has drifted from the API is worse than no sample, and this API is eight months old and still moving (`listen` and `imagePart` landed a day after the rest). The cheapest mechanism: **ship the samples as a real vault app** — one that exercises `available`, `chat`, streaming, `cancel`, `usage`, `models`, `imagePart` and `listen` — and publish it as both the demo and the test. It would also be the best possible demonstration of surface 3. --- ## 4. The demo the site should ship Everything above argues for one artefact: **a vault app that is the documentation.** - It exercises every call, so the samples are tested by existing. - It is openable by anyone with a read key, so the docs are runnable rather than readable. - It demonstrates surface 3 while the reader is one click from surfaces 1 and 2. - It is the estate's own pattern — *"the maps live in the source and are reviewable in a diff"* applied to an API reference. ⚠️ **With one condition, from `03__` §6:** a vault with an LLM key configured **carries a credential**, and publishing its read key shares the ability to spend it. So the demo vault needs a **`shared`-tier key with hard `maxCostPerSession` and `maxCallsPerSession` caps**, deliberately chosen for publication — or it needs to ask the visitor for their own key, which is the BYOK precedent from the Article 9 Lab and probably the right answer for a public demo. **Decide that before publishing the vault, not after.** `08__` Q4. --- This document is released under the Creative Commons Attribution 4.0 International licence (CC BY 4.0). ============================================================================== /briefs/07__boundaries-and-licensing.md ============================================================================== # 07 — Boundaries and licensing ## 1. Licensing **This site's content is CC BY 4.0**, consistent with the network. Stamp every raw markdown document; gate with `licence-audit.py --check`. **The code quoted throughout is Apache-2.0** — `SGraph-AI__App__Send` and the vault-html guides carry it. Retain the notice where snippets run long, and do not imply the code carries the site's CC BY licence. **The samples in `code__chat-pane-samples.md`** are written for this pack and are CC BY 4.0. The `sg.llm.*` calls inside them are the shipped API; the surrounding UI is ours. Say so, so a reader knows which half is a contract and which half is an example. --- ## 2. ⚠️ Do not create a second source of truth The corpus already refused to do this, deliberately, and gave its reasons: > *"**No — and deliberately.** It belongs in the two homes that already exist: `AUTHORING.md` — the canonical `window.sg.*` contract. **Adding a competing document would create a second source of truth that drifts.**"* That was about a proposed skill, and **the same logic applies to this site.** A hand-written API reference on `llms.sgit.ai` will drift from `AUTHORING.md` within a release. **The resolution:** `AUTHORING.md` stays canonical; the site **generates** its reference from it and says so on the page. That gives a human-readable public surface without a competing contract — which is the gap the corpus's own reasoning leaves open, since `AUTHORING.md` is an agent authoring contract that no human reader will find. `08__` Q1. --- ## 3. Do not publish - **Any OpenRouter key, or any vault key.** Rule 13 of the estate's code rules: *"No vault keys in Git… If one appears in a diff, block the commit."* This site's subject matter makes it the most likely place in the estate for a key to end up in a sample. - **The demo vault's write key**, if the demo in `06__` §4 is built. Read key only, and only after the spend caps are set. - **`library/alchemist/materials/`** — the whole tree. - **`team/roles/grc/reviews/02/19/`** — names a private individual with signature blocks. - **`team/roles/appsec/reviews/02/21/…pki-architecture-security-revised.md`** — classified as *"an attack roadmap for live code."* - **The competitor and positioning briefs.** **And a rule specific to this site:** every sample must use a placeholder that is obviously a placeholder. Not a realistic-looking key. **Add `sk-or-`, `sgit_vk1_` and OpenRouter key shapes to the CI key-leak check** before the first sample page ships. --- ## 4. Publish the security gap — do not soften it `03__` §5. The corpus states plainly that the CSP egress lockdown is not built and that this is *"the gap that turns the current design from a convenience into a guarantee."* **Publishing a known limitation of your own security design is the estate's own standard** — the vault catalogue publishes its own key-exposure incident; the reality-document rule is *"briefs are aspirations, not facts."* A site that omitted this would be below the standard the rest of the network keeps. **Do not** publish an exploitation path, and do not frame it as a vulnerability disclosure. It is a scope statement: *the bridge protects the credential you trusted us with; it does not prevent all egress.* --- ## 5. Network boundaries | Site | Owns | Boundary | |---|---|---| | **`llms.sgit.ai`** | The chat pane, `sg.llm.*`, the LLM security model, provenance, providers, local models | — | | `sgit.ai` | The vault product, the catalogue, the demos | **The closest neighbour.** `AUTHORING.md` and the vault UI belong there; the LLM capability *inside* them belongs here. Agree who owns the `/vault` chat-panel page — recommendation: **this site owns the capability, `sgit.ai` owns the product tour** | | `coding.sgit.ai` | How code is written | **The samples follow its component conventions.** If `sg-llm-chat` gets built (`04__` §3), that site owns the component pattern and this one owns the LLM contract | | `risks.sgit.ai` · `standards.sgit.ai` | Risk and instruments | **They own the grounding ladder.** State it in three lines and link out — `05__` §2 | | `open-source.sgit.ai` | The open-source position | Sovereignty applies sharply to model providers (*"one SLA away from losing access"*); the agent-era theses are shared. Two links | | `graphs.sgit.ai` | Graph theory | RAG-over-graphs sits on the boundary. Light link | | `sg-compute.sgit.ai` | The compute platform | **Owns the `ollama` and `local_claude` specs.** This site links to them for the local-model story; that site owns the specs themselves | | `newsroom.sgit.ai` | The future of news | Shares training-data licensing and the fact-graph-as-training-material thread | --- ## 6. House style - **Every sample is runnable, and tested by being a real vault app** (`06__` §4). - **Every API claim is traceable to `AUTHORING.md`**, with the date the contract shipped. - **Estimates are rendered with `~`.** The site's own cost figures follow the rule it teaches. - **State the grant before the call.** Default-deny is the model; the grant is the first thing a reader needs. - **Publish the traps.** The 8190 bug shipped three times — that is documentation, not embarrassment. - **-ise, not -ize**, and no em-dashes in the markdown deliverables. --- This document is released under the Creative Commons Attribution 4.0 International licence (CC BY 4.0). ============================================================================== /briefs/08__gaps-and-open-questions.md ============================================================================== # 08 — Gaps, open questions and honest tensions --- ## 1. Must be built fresh | # | Item | Why | |---|---|---| | **G1** | **The website chat pane** | **Half the commission, and the half with almost no existing material.** No component, no documented pattern, no code. `04__` §3 recommends a `sg-llm-chat` web component with a pluggable transport, built to the estate's component conventions, serving all three website options | | **G2** | **A human-readable API reference** | The full contract exists only inside a 9,487-word agent authoring document. **Extracting it is the single highest-value publishing act on this site** — generated, not hand-written (`07__` §2) | | **G3** | **The demo vault app** | `06__` §4. One app that exercises every call, published as both the documentation and its test. Also the best possible demonstration of surface 3 | | **G4** | **An eval suite** | There is none. No benchmark, no regression test for prompt behaviour, nothing that would catch a model swap changing an output. For a site about LLM engineering this is the most conspicuous absence | | **G5** | **Structured-output guidance** | 41 files. `Type_Safe` validates the *result*; nothing documents how the *request* is shaped to get a valid one | | **G6** | **Cost analysis** | `cost per token` appears in **2 files**, despite a full two-source reconciled ledger with CSV export. **The data exists and nobody has looked at it** | | **G7** | **Model routing** | **1 file.** No fallback chain, no cost/quality tiering, no routing logic | | **G8** | **A prompt-injection position** | 92 files mention it; none addresses the case this site's own product creates. See Q3 | --- ## 2. Open questions | # | Question | Where it stands | |---|---|---| | **Q1** | **How does a public reference avoid becoming a second source of truth?** The corpus refused to create one, with reasons | `07__` §2 proposes: `AUTHORING.md` stays canonical, the site generates from it and says so. **Needs a decision and a build step, not a convention** | | **Q2** | **Who owns the `/vault` chat-panel page — this site or `sgit.ai`?** | Recommendation: this site owns the *capability*, `sgit.ai` owns the *product tour*. Unresolved | | **Q3** | **What stops an attached vault file from injecting the prompt?** The panel attaches file contents to the model's context. Those files are untrusted. The 24,000-char budget and the `TRUNCATED` marker are honesty mechanisms, **not injection defences** | **The most important open question on the site**, and it is unaddressed anywhere in the corpus. **Do not publish an injection page until this has an answer** | | **Q4** | **Can the demo vault publish a read key at all?** A vault with an LLM key configured carries a credential; publishing its read key shares the ability to spend it | `06__` §4: either a `shared`-tier key with hard caps chosen for publication, or BYOK following the Article 9 Lab precedent. **Decide before publishing, not after** | | **Q5** | **When does the CSP gap get closed, and what does the site claim until then?** | `03__` §5. The scope statement is *"we protect the credential you trusted us with"*, not *"nothing leaves this frame."* That is publishable — but it is a weaker claim than the front page wants to make | | **Q6** | **Is BYOK-in-the-browser acceptable for a public page?** | The Article 9 Lab does it deliberately. It is honest and it converts badly. Is that the right trade for `*.sgit.ai`? | | **Q7** | **Should transcription model choice be per-vault?** | It is a constant today. The chat model and the audio model are necessarily different and only one is a setting | | **Q8** | **What happens to `sg.llm.*` in nested vaults?** | ViV kernels do not relay it. An app inside a nested vault **silently** has no bridge — silently is the problem | --- ## 3. Honest tensions 1. **The thesis and the gap sit in the same sentence.** *"Your app never holds the key"* is true. *"Nothing leaves this frame"* is not, and the corpus says so. The site has to make the strong claim and the qualification together, on the same page, or it is overselling. 2. **The best documentation is the hardest to find.** `AUTHORING.md` is genuinely excellent — the 8190 explanation, the greenlet reasoning, the labelled-cost contract — and it is a 9,487-word agent authoring file that no human reader will ever open. **The quality is not the problem; the discovery layer is.** That is the same finding the agent-access report made about the whole estate. 3. **Half the commission is thin.** The vault story is shipped, complete and documented. The website story is three options and one adjacent precedent. **Say which half is which** rather than levelling them. 4. **A full ledger and no analysis.** Every call is logged with a generation id, tokens, cost and latency, exportable as CSV — and `cost per token` appears in two files. The instrumentation is better than the use made of it. 5. **No evals, in an estate whose thesis is provenance.** The whole position is *"you must be able to say where an output came from."* There is no mechanism for saying whether an output was any good, or for noticing when it stops being. 6. **The honesty mechanisms are the best work and the least visible.** One shared file budget, `TRUNCATED` in the model's own text, estimates never rendered as bills, images clearing after one turn, recording announced in words rather than an icon. **Each is a small refusal to mislead**, and collectively they are more persuasive than any feature list — and none of them is published anywhere. 7. **Publishing a demo vault teaches the thing and creates the risk.** A configured vault carries a credential. The best demonstration of the design is also the clearest instance of its standing warning. --- ## 4. Loose ends worth an hour each - **Verify the API against the shipped code**, not just against `AUTHORING.md`. The contract is eight months old and moved twice in two days when `listen` and `imagePart` landed. - **Add key shapes to the CI leak check** — `sk-or-`, `sgit_vk1_`, OpenRouter formats — before the first sample page ships. - **Confirm the current default-model list.** It was corrected once already after alphabetical matching picked the oldest model on the key. - **Check whether `hud.show.llm` is still the config key**, and whether `minimal` mode still defaults it off. - **Establish whether the offline Ollama chat still runs**, and whether its FastAPI proxy is the same shape as the two sg-compute specs. - **Find out what the audio model constant currently is.** The docs say `google/gemini-3.5-flash` *by default*, which implies configurability that Q7 says does not exist. - **Ask whether Phase 4 minted credentials are scheduled.** They are described as *"the commercially load-bearing piece"*, and the site's strongest claim depends on them. --- This document is released under the Creative Commons Attribution 4.0 International licence (CC BY 4.0). ============================================================================== /briefs/LICENCE.md ============================================================================== # Licence ## This pack Everything in this brief pack — the nine numbered documents, `code__chat-pane-samples.md`, `09__source-manifest.csv`, this file and `README.md` — is released under the **Creative Commons Attribution 4.0 International licence (CC BY 4.0)**.

No code — surfaces 1 and 2 The vault chat panel (`/vault` → **✨ AI Chat**) and the app-side panel (`/en-gb/app/` → **✨ AI**) are host chrome. Nothing to build. The only thing an app author can express is a chrome preference in `app.json`: ```json { "entry": "index.html", "hud": { "show": { "llm": true } } } ``` `false` hides the button if it would clash with your own UI; `true` forces it on in `minimal` mode, where it is off by default. It is a preference about chrome, not authority. --- ## 1. The minimum viable chat pane `app.json`: ```json { "entry": "index.html", "permissions": { "llm": { "chat": true } } } ``` `index.html`: ```html ``` `chat.js`: ```js const chat = document.getElementById('chat') const fallback = document.getElementById('fallback') const log = document.getElementById('log') const composer = document.getElementById('composer') const q = document.getElementById('q') const messages = [] // 1. ALWAYS check availability before rendering a chat UI. // It depends on runtime state: key configured, read-only session, budget spent. const a = await sg.llm.available() if (!a.ok) { fallback.hidden = false fallback.textContent = { ENOKEY: 'No AI key configured for this vault — Settings → AI models.', EPERM: 'This app was not granted AI access.', EREADONLY: 'The AI key is owner-sealed and this is a read-only session.', }[a.reason] ?? `AI unavailable (${a.reason})` } else { chat.hidden = false } composer.addEventListener('submit', async (e) => { e.preventDefault() const text = q.value.trim() if (!text) return q.value = '' messages.push({ role: 'user', content: text }) append('user', text) const bubble = append('assistant', '') try { // 2. The terminal reply is authoritative. onToken is a UX affordance. const res = await sg.llm.chat({ messages }, (delta, acc) => { bubble.textContent = acc }) bubble.textContent = res.content messages.push({ role: 'assistant', content: res.content }) } catch (err) { // 3. Branch on err.code, never on message text. bubble.textContent = `[${err.code}] ${errorText(err.code)}` } }) function append(role, text) { const el = document.createElement('div') el.className = `msg ${role}` el.textContent = text log.append(el) log.scrollTop = log.scrollHeight return el } function errorText(code) { return { EBUDGET: 'Spend cap reached for this session.', ECONSENT: 'You declined the request.', EMODEL: 'That model cannot handle this request.', EABORT: 'Cancelled.', EPROTO: 'The provider failed. Try again.', }[code] ?? 'Something went wrong.' } ``` **Three rules are load-bearing and all three are in the comments:** check `available()` before drawing, treat the terminal reply as the truth, branch on `err.code`. --- ## 2. Adding cancel The promise carries its own request id: ```js let inFlight = null async function send(messages, bubble) { const p = sg.llm.chat({ messages }, (delta, acc) => { bubble.textContent = acc }) inFlight = p.requestId stopBtn.hidden = false try { return await p } catch (e) { if (e.code === 'EABORT') return null // partial text is already rendered throw e } finally { inFlight = null stopBtn.hidden = true } } stopBtn.onclick = () => { if (inFlight) sg.llm.cancel(inFlight) } ``` --- ## 3. A cost meter that does not lie ```json { "permissions": { "llm": { "chat": true, "usage": true } } } ``` ```js async function refreshMeter() { const u = await sg.llm.usage() meter.textContent = `${u.calls} calls · $${u.cost.toFixed(4)} · ${u.remaining.cost ?? '∞'} left` } ``` And per call — **the `~` is the rule, not a nicety**: ```js const res = await sg.llm.chat({ messages }) costPill.textContent = res.cost.estimated ? `~$${res.cost.value.toFixed(4)}` // computed from tokens × list price — NOT billed : `$${res.cost.value.toFixed(4)}` // reconciled against /generation ``` > *"`estimated: true` means it was computed from token counts × list price, not billed. Render estimates with a `~`. **Never show one as a bill.**"* Note that `usage()` covers the **whole session**, including the host panel's own calls — one bill per session, not one per surface. --- ## 4. A model picker that cannot be wrong ```json { "permissions": { "llm": { "chat": true, "models": true } } } ``` ```js const models = await sg.llm.models() // already filtered by the vault's allow-list picker.append(...models.map(m => { const o = document.createElement('option') o.value = m.id o.textContent = m.name ?? m.id return o })) // then pass it per call await sg.llm.chat({ model: picker.value, messages }) ``` **You do not filter this list.** The host returns only what the vault allows, so a picker built from it is automatically correct — including when the allow-list changes. --- ## 5. Attaching an image ```js dropZone.addEventListener('paste', async (e) => { const item = [...e.clipboardData.items].find(i => i.type.startsWith('image/')) if (!item) return const part = await sg.llm.imagePart(item.getAsFile()) // Blob | Uint8Array | ArrayBuffer | data: URL const res = await sg.llm.chat({ messages: [...messages, { role: 'user', content: [ { type: 'text', text: q.value || 'What is in this image?' }, part, ] }] }) append('assistant', res.content) }) ``` **Use `imagePart()`. Do not encode it yourself.** It runs in your frame with no host round trip, and it chunks base64 at **8190, not 8192** — because `8192 % 3 === 2`, so a 8192-sized chunk emits `=` padding mid-string and `atob()` rejects it. *"This codebase has shipped that exact bug three times."* png / jpeg / webp / gif only. Not svg. An `EMODEL` error will **name the model** that cannot see. **And clear the attachment after sending.** The host panel does, deliberately: an image left attached would silently re-send and re-bill on every turn. --- ## 6. Voice input ```json { "permissions": { "llm": { "chat": true, "listen": true } } } ``` ```js micBtn.onclick = async () => { try { micBtn.disabled = true const { text, cost } = await sg.llm.listen() // opts: {maxMs, model, prompt} q.value = text q.focus() } catch (e) { if (e.code === 'ECONSENT') return // declined — not worth showing if (e.code === 'ENOMIC') showTypeInstead() else showError(e.code) } finally { micBtn.disabled = false } } ``` **Your frame never touches audio** — a sandboxed frame has no `navigator.mediaDevices` at all. The host records, shows the indicator on its own chrome, transcribes with the vault's key, and hands you text. `listen` is a **separate grant, never implied by `chat`**, and asks for consent every time by default. --- ## 7. A file-grounded pane, following the host panel's own rules If you attach vault files to the prompt, copy the three honesty mechanisms the host panel uses. They are the difference between a demo and something you can trust: ```js const BUDGET = 24_000 // ONE budget shared across all files async function buildContext(paths) { const parts = [] let spent = 0 for (const path of paths) { const text = await sg.vfs.readText(path) const share = Math.max(0, Math.floor(BUDGET / paths.length) - 64) const clip = text.length > share parts.push( `--- ${path}${clip ? ' (TRUNCATED)' : ''} ---\n` + // the MODEL sees TRUNCATED text.slice(0, share) ) spent += share } return parts.join('\n\n') } ``` 1. **One budget shared across all files**, not one each — so a second file cannot silently double the bill. 2. **`TRUNCATED` goes in the text the model sees**, so it cannot pretend to have read the whole file. 3. **Re-adding a file replaces its contents**, so it refreshes after an edit instead of duplicating. --- ## 8. The checklist before you ship - [ ] `available()` called **before** any chat UI is rendered - [ ] Every `catch` branches on `err.code`, never on message text - [ ] All nine error codes have user-facing text: `EPERM` `ECONSENT` `ENOKEY` `EREADONLY` `EBUDGET` `EMODEL` `EABORT` `EIMGSIZE` `EPROTO` - [ ] Estimated costs rendered with `~`; never shown as a bill - [ ] Image attachments cleared after one send - [ ] File context under one shared budget, with `TRUNCATED` visible to the model - [ ] Model picker built from `models()` and not filtered locally - [ ] Only the grants you use are declared — and `listen` only if you actually record - [ ] You have checked whether **surface 1 or 2 would have done the job with no code at all** --- This document is released under the Creative Commons Attribution 4.0 International licence (CC BY 4.0).
