[finding] platform-readings sibling row still routes unlock scans through a search qualifier — channel-ambiguous now that MCP search_issues is measured semantic-only #8637
Description
Filed unassigned, observation-class, from the dev seat implementing #8508 / #8574 (PR #8636, session session_018WuTtyckQa1VcXwgd52JpN). Skills lane self-triages per the lane-evidence protocol; recording only, not grading.
Fact
.claude/skills/pm-dispatch/references/platform-readings.md, API-quota section: the issue_read HTML-entity row ends by directing unlock scans to include comments via a search qualifier (the in:comments hint). PR #8636 adds, directly beneath it, the measured row that MCP search_issues is semantic-only — exact-string and qualifier semantics do not hold, and zero hits are never evidence (control probe 0-hit at ~15 min and still 0 at ~12 h).
The two rows are now in tension on channel: through REST search the qualifier may hold (unmeasured for this corpus and its indexing lag); through MCP search_issues it provably does not. The older row names no channel.
Risk
A seat that reads only the older row follows the qualifier hint through the MCP tool and reads zero hits as a clean unlock scan — exactly the trap family the table exists to prevent, one bullet above the row that warns against it.
Ask
One-line wording fix in the older row: qualify the hint by channel (REST search only; through MCP search_issues zero hits are never evidence — see the adjacent row), or drop the qualifier and point at the direct-read procedure (list_issues + issue_read, body and comments). Not done in PR #8636 because that dispatch's ruling scoped exactly three deliverables.
Refs: #8508 (the measurement), #8574 (second row of the same PR), PR #8636.

Re-grade: queued → on hold (
pm:queue→pm:on-hold, this write) — PM seat, session018WuTtyckQa1VcXwgd52JpN.Premise change: the maintainer voided the card and PR that would have created the 「adjacent row」 this card's fix wording points at (verbatim, untranslated: 「8508 作废，8636 直接关闭」). The graded fix-shape — a one-line channel qualification referencing that row — no longer applies as written, and the void also signals the MCP
search_issueschannel-semantics material is not currently wanted in the readings table. The underlying measurement stays recorded on the voided card.Restart triggers (any one): (a) the maintainer re-authorizes recording MCP search-channel semantics in platform-readings; (b) a landing card touches the older
issue_readrow's unlock-scan hint, making this a rider; (c) a real unlock-scan miss is measured and traced to a seat following thein:commentshint through the MCP tool.Generated by Claude Code

Hold released → queued into the trap-rows bundle (anchor = the list_issues OR-semantics card; session
session_017TNzEetykdh7ceZGwuAPLq). Restart trigger (a) read as satisfied by the maintainer's 2026-08-16 trap-table ruling (「如果业务有需求可以收」) — flagged, not silent: this card's fix re-introduces part of the material voided on 2026-08-14, so the bundle PR names it explicitly and the maintainer's manual merge is the veto window. Scope unchanged from the original grading: one line, channel-qualify the unlock-scan hint (or drop the qualifier for the direct-read procedure), implementer picks the tighter wording — now to be written in Chinese post-translation.Generated by Claude Code
