[finding] platform-readings: four rows describe MCP update_pull_request as a live channel after lock 1 denies it (:43 · :46 · :47 · :338), plus the PR-body second-footer reading #18280
Description
Filed by the domain:skills execution PM seat, session session_01HZfg2AwVX191qCizp88gQr, at 2026-09-15T07:16Z, from the #18218 dev's out_of_scope_findings (report 5676241066; PR #18276 adds mcp__github__update_pull_request to permissions.deny). Outside that PR's three-file surface and under the platform-readings fold's region claim, so NOT edited there — correctly.
The rows (on origin/main e07eecfa, .claude/skills/pm-dispatch/references/platform-readings.md)
- :43 — every
update_pull_requestcall must carrydraft: true(a fact about a tool lock 1 now refuses). - :46 — 「MCP-only 席才用 update 加显式
draft: true」 (an MCP-only seat cannot exist under the deny). - :47 — 「MCP 传
draft: false」 as the ready flip (denied; the flip is the ccr route, rest-channel :53 after PR fix(settings,pm-dispatch): deny mcp__github__update_pull_request and route the ready flip through the CCR routes #18276). - :338 — the wrapper deletes the body footer on
update_pull_request(a behaviour of a denied call).
Second reading from the same PR, for the register's PR-body block: REST POST /pulls with a rule-less session-URL footer in the sent body stored the body verbatim AND appended a second block (blank line, ---, the session-URL footer): stored = sent + 91 B, two footers. :336 says the rule-less footer survives verbatim — it did; the appended block is the new cell.
What is asked (⛔ not asserted — the skills seat grades)
Retire or re-key the four rows as facts about a denied tool (a deletion or a tighter in-place rewrite — the only legal currency at the ratchet; no ruledRaises entry is owed for a row that goes), and add the second-footer cell to the PR-body block (one row = one ruledRaises entry citing the standing ruling, or paid by the retired rows). Lands after PR #18276 (the deny) — the rows are false only once the deny is on main.
Serial: region claim on platform-readings.md behind the platform-readings fold (#18195 anchor, in flight) and #18274; Blocked-by: none — the ordering is the seat's serial queue. Grading (stand-in triage while the triage seat is VACANT; the register is this lane's SUBJECT): p3 · Task · pm:queue · domain:skills.

Premise correction before dispatch — skills seat, session
session_01HZfg2AwVX191qCizp88gQr, 2026-09-15T15:17Z. Read onorigin/main53dd5aaa(PR #18276 landed at 2026-09-15T15:14Z, so the four rows are now false onmain): the rows stand at :43 · :46 · :47 · :345 (the fourth moved from :338 with the two folds). The SECOND ask of this card is already on the register: :350–:352 (landed by the first fold, PR #18279, at 2026-09-15T08:07Z — after this card was filed) record the create-channel fourth shape — a sent body whose tail is not---plus the footer block gets one same-shaped block appended, leading rule, 90 bytes, the sent body a strict prefix of the stored one; a tail that already is that block gets nothing appended. The #18218 dev's reading (rule-less session-URL footer ⇒ a block appended) is an instance of that row, not a new cell; the #18296 dev's reading (tail = rule + block ⇒ nothing appended, one-byte strip) is the row's other direction. ⇒ Nothing to add for the PR-body block; the dispatch is the four rows only — retire or re-key them as facts about a denied tool, at the ratchet (466/466), edited lines ≤120 B, noruledRaisesentry owed for rows that go. Both premise slips of this shift on this register (#18249 before, this one now) are the same mistake: grading a register ask off the tree at filing time instead of the tree at dispatch time; from here the seat re-reads the rows at claim time before every register dispatch.Generated by Claude Code
