route-dedup.ts: two open unowned defects (windowing collapse, unrecoverable summary)
REOPENED SCOPE 2026-08-17 (pm-venus-cc): this is VENUS-321/324's dedupAllow settle defect, confirmed FIRING IN PRODUCTION same day — scrp-applog-mars phantom '9 MORE suppressed alerts' burst traced to zero new appEvents rows. Mechanism (coder-venus-cc, reproduced against real stepRouteDedup): a route-suppressed row is never settled, so the cursor holds and the 5-min catchUp re-SELECTs it; seen is deleted with its window at flush, so the next sweep hands the same rows to an empty map — one opens a fresh window and pages, the rest count as new suppressions. Measured: 10 rows written once -> 9 summaries (9,8,7...1) and 10 pages over 90 min, zero new rows. Fix = verified-summary settle, exactly route-dedup.ts:986's named prerequisite, and the same three-requirement contract VENUS-321 specified (event-time window + await/branch/defer-delete on confirmed postAlert + per-row identity/disposition retained). BLAST RADIUS: applog-listen@.service WorkingDirectory pins to venus/, so venus/mars/pluto/ayudarg/enamel all execute this file — diff needs audit-venus-ca review before push regardless of Class-S/A file-count heuristics, per blast-radius not file-count. Original VENUS-321 fixture/measurement history (mars's 13-row reconstruction, ayudarg 772-row page_not_found fixture, the caller-side-void unverifiable-delivery finding) carries forward unchanged; read VENUS-321's full event log before implementing, do not re-derive.

was: Comments corrected in a40aae9 to stop pointing at a nonexistent route-throttle successor after VENUS-321 was canceled — route-dedup.ts is the live shipping throttle with no replacement queued. Two real defects recorded in-code there, now unowned: (1) wall-clock windowing collapses rows enqueued ms apart into one window even when their actual events are days apart; (2) its summary is count-only, contents unrecoverable after the fact. Filed so these don't silently read as handled just because VENUS-321 closed.

SHIPPED 18555cc v1.13.13 (+37b1600 v1.13.14 comment-only), audit-venus-ca PASS after 3 rounds. Fixed phantom '9 MORE suppressed alerts' burst (scrp-applog-mars, zero new appEvents rows behind it): route-suppressed rows were never settled, so the 5-min catchUp re-SELECTed them forever while the seen id-guard died with its window at flush — 10 rows once produced 9 decaying summaries + 10 pages over 90min. Fix = verified-summary settle per VENUS-321's contract (event-time window + await/branch/defer-delete-on-confirmed-postAlert + per-row identity). All 6 applog-listen@ units restarted fleet-wide (ayudarg/enamel/mars/pluto/terra/venus). Live convergence independently confirmed by pm-mars-cc: exactly 6 events delivered (1 page + 1 named 5-row summary) matching the sweep count, zero decaying repeats since. Cosmetic follow-on filed as VENUS-376.
