docs(pm-dispatch): drop the dissolved engine-lane investment-freeze parenthetical

[os-litant]

Fixes #12672

What

Drops the stale investment-freeze parenthetical from the domain:engine row of the pm-dispatch domain-lane table (.claude/skills/pm-dispatch/SKILL.md, line 266). The freeze it described (maintainer, 2026-08-05, driver-memory / driver-mongodb) was dissolved by two maintainer rulings on 2026-08-11 recorded on the #5499 anchor (comments 5249019855 and 5252526378): 「5499 解冻 mongodb 相关开发,继续全速推进」 and 「driver-memory 也解冻…」. The DROP option was chosen (PM preference): the parenthetical is deleted rather than re-dated, so the row cannot go stale on this axis again — #5499 carries its own history.

Premise verified on disk before editing: the head note of packages/spec/src/data/aggregation-conformance.ts (lines 141-143 at this branch's base) records both lifts — "the maintainer lifted the #5499 investment freeze for driver-mongodb on 2026-08-11 and for driver-memory later the same day".

Before / after (the changed fragment of the domain:engine row)

Before (full row: 765 bytes, the file's widest table row and the seed of its ratchet pin):

packages/drivers/driver-*(维护者 2026-08-05 对 driver-memory / driver-mongodb 族有投入冻结指令;formula / driver-sql 不受影响)—— 车道合并(维护者 2026-08-19…)

After (full row: 642 bytes):

packages/drivers/driver-* —— 车道合并(维护者 2026-08-19…)

No issue number was added to the file (id-lint pattern held: check:pm-skill-id-lint green below); dates and the anchor's own record carry the history.

Ratchet arithmetic

Metric	Before	After	Ceiling / pin	Headroom after
SKILL.md line count	1005	1005	1005 (zero-headroom)	0 — net-0 edit
Widest table row (this row)	765 B	642 B	pin 765 (shrink-only)	123 B paid down

The ratchet gate now prints the opportunistic-tighten hint ("lower the pin to 642"). The pin lives in the gate script scripts/pm/check-skill-line-ratchet.mjs; tightening it is a gate-script edit outside this card's dispatch scope, so it is reported to the PM as a follow-up instead of ridden here.

Gates

Derived with node scripts/pm/dispatch-gates.mjs --repo objectstack-ai/objectstack (9 matched families for this diff; derivation asserted against this checkout's origin and re-run after the final commit). Full union re-run at final commit 38f278a0e; verdict lines below are quoted from that run's logs (long lines truncated at "…").

NOT MEASURED locally, by design: the queue guard's main entrypoint reads GITHUB_EVENT_PATH (the CI workflow event payload) and refuses without it — "⛔ Governed Surface Queue Guard: could not read GITHUB_EVENT_PATH (ENOENT…)". Its offline --self-test (the runnable local form its own header documents) passed, exit 0; the real verdict lands in CI on this PR. First-pass prerequisite refusals (@objectstack/formula, then @objectstack/lint not built — "PREREQUISITE NOT MET … Nothing was measured") were resolved by building both, then the gate ran and passed; those refusals are not findings.

Changeset

None — .claude/** is on the no-release closed list; skip-changeset label applied at PR-open with read-back.
