docs: STATUS thirteenth block, alpha product-trust lane merges and corrections

[Chris0Jeky]

Summary

Docs only. Adds the thirteenth v0.3 integration-wave block to docs/STATUS.md (main bf93efc4d to 540bc2abb, 2026-09-05), recording the alpha product-trust lane merges since the twelfth block with their exact heads, merge commits, evidence, review dispositions and residuals: #2630, #2658, #2662 (Review), #2631, #2659, #2668 (Inbox), #2635 (shortcuts), #2666 (Board), #2663 (guards), plus the platform lane's merge packets #2617, #2619, #2660 and #2665 recorded verbatim. The "Not shipped reality" bullet names the open #1949 AC4 inventory work, the slices held behind another session's #2629 and #2654, the K-section rulings they wait on, and the residual issues opened this wave.

The corrections paragraph records, verbatim from the platform lane's #2660 packet, the three corrections to the #2416 entry (the activate-listener reading did not reproduce; a rejected activate waitUntil does not abort activation; the #2475 browser-level regression landed), with the #2639 re-measurement note; a trailing pointer clause on the #2416 bullet itself (line 80) sends a section-reader to those corrections so "rejects activation on failure" is not read as an operative safety property. It also records three shipped-reality gaps the lane's audits found: PR #2426 (#1999 item 4), PRs #2158 and #2165 on #2090 with the stale "Blocked behind parked PR #2165" sentence withdrawn, and PR #2166 as the #1940 baseline.

Refs #2214, #2215, #1940, #1949, #1999, #2090, #2571, #2621, #2640, #2639.

Verification

• node scripts/check-docs-governance.mjs: passed at the head.
• git diff --check: clean.
• Every merge commit, head SHA and count was copied from this session's merge records and the workers' reports; the platform-lane entries and the #2416 corrections are that lane's packets verbatim.

NOT verified: nothing executable changes; the block's claims about runtime behaviour are the merged PRs' own evidence, linked by PR number.

Review record (alpha product-trust lane, docs-only PR; Codex credits exhausted so one fresh-context independent review carries the gate).

Reviewer: one read-only reviewer subagent over the diff at d91e8d7 and the tree at the head. Verdict: FIX-FIRST on one HIGH, fixed at f74a838 together with the MEDIUMs and LOWs:

• HIGH: the corrections paragraph still said "titles-only density stays open", a snapshot from the audit taken before feat(board): titles-only card density on the Paper board #2666 merged, contradicting the block's own feat(board): titles-only card density on the Paper board #2666 entry and the two planning docs feat(board): titles-only card density on the Paper board #2666 corrected; it now says titles-only shipped later that day in PR feat(board): titles-only card density on the Paper board #2666.
• MEDIUM: the fix(review): localize the degraded-queue warning, announce recovery, keep it visible #2630 entry's first sentence stated the rail-below-warning layout as fact while the same bullet retracts it; it is now marked as intent with the inert-handshake finding and [Frontend][Review] Degraded-queue follow-ups: decision rail sticky is inert, recovery sentence retired by explicit loads #2638 inline, and "are corrected there" now says the comments are recorded on [Frontend][Review] Degraded-queue follow-ups: decision rail sticky is inert, recovery sentence retired by explicit loads #2638 for correction.
• MEDIUM: the header claimed a second read-only pass for every round-2 diff that changed logic; it now names the four PRs that carried one (fix(review): localize the degraded-queue warning, announce recovery, keep it visible #2630, fix(inbox): pin the foreground detail state, coalesce count refreshes, clear the generation maps at logout #2631, fix(shortcuts): keep board keys behind an open modal and tighten the shell key guards #2635, fix(inbox): drop pre-logout list snapshots by session epoch and report dropped detail reads #2659) and states that test(guards): scan wrapper buttons for dead affordances and name the primary-action inventory #2663's round 2 changed guard rules and comments only with no second pass; the fix(shortcuts): keep board keys behind an open modal and tighten the shell key guards #2635 entry now records its verification pass and its three LOWs.
• LOWs: the line-80 pointer and the corrections paragraph agree on three fragments (two safety-relevant); the duplicated framing sentence is removed; the block range names bf93efc as the twelfth block's own merge and accounts for the commits between 5f2d3fa and bf93efc (docs: coordination lane in the eleventh STATUS block, SC-10 #2608/#2610, D-12 unclaimed PR author #2616 and docs: STATUS twelfth block, alpha product-trust lane merges and corrections #2628, recorded in the eleventh and twelfth blocks); the Not-shipped bullet names PR test(e2e): route-affordance inventory and smoke walk for #1949 AC4 #2673 for the AC4 inventory.

Confirmed by the reviewer against the tree: every code-level claim in the block (the degraded-queue keys and recovery signal, the hoisted region and the sticky and offset rules, the malformed-target predicate and expectedStatuses, the honest-empty cards, the session epoch, outcome union and re-read, the history-detail generation, the shell selector, markers and ownership rule, the titles-only preference and toggle, the wrapper scan and inventory header, the platform-lane files); the three #2416 replacement quotes verbatim against line 80 and the pointer clause; the #2426, #2158, #2165 and #2166 facts; zero em dashes; placement and headers per convention. Not verified by the reviewer: merge SHAs, PR and issue states, test counts and CI outcomes (this session's merge records and the workers' reports are the source).

Merge gate: ci-required green at f74a838, aged three minutes, then merge commit.
