A section for collaborators and their agents, and the twins stop dropping things

A new section for briefing people who work with us — and, since they work the way we do, for the agents they hand our material to.

• Working with us↗ — how this estate works in six lines, the seven hard rules that apply to anything produced on our behalf, and what you need to get set up (for the first brief: nothing but a browser). In the More menu rather than the top bar, because it is an operational page and the bar is at its seven-entry limit.
• Brief B1 — power user and tester of Agent Behaviour Policies↗. The first task. It opens with a prompt written to be pasted whole into an agent: who we are, what we are selling right now, the two deadlines that shape everything, the seven rules, and a reading list of ten sources across abp.sgit.ai, store.sgit.ai, risks.sgit.ai, sgit.ai and this site — each with the .md address to hand an agent and a line on why it is on the list. Then five steps ending in the one thing we actually want: an instrumentation table testing the claim that the second policy of a known deployment shape takes minutes rather than days. Nobody has checked, and that number decides whether any of this can be priced.

The brief deliberately does not state a rate, a start date or how many hours. This page is public; those are between the two people involved. They are listed as an explicit checklist of what the engagement owner still owes, so nobody mistakes their absence for an oversight.

The markdown twins were dropping content, and that mattered more than usual here. Two bugs in the extractor, both fixed:

• Preformatted blocks were dropped entirely. The extractor handled a fixed set of tags and <pre> was not among them — so the collaborator prompt, which is the single most important thing on its page and the reason the twin exists, was absent from the twin. Also missing: the worked curl examples on the agents page↗, gone since v1.0.0. <pre> now becomes a fenced block, whitespace intact.
• Nested lists came out scrambled. A non-greedy regex matched an <li> to the first </li>, which for a list item containing its own sub-list swallowed the item's heading and prose into one bullet and then emitted the sub-list as siblings. Close tags are now matched with nesting counted, and a block element containing block children has its children emitted rather than being flattened. This corrected summit.md as well.
• And the print-only PDF cover was being read as content, so every Lab twin carried its own headline twice. Excluded.
