Release-isolated slice built from 41ba38e. Ships ONLY the event-integrity +
publication + lineage-canary closure; the 90-path development tree stays
undeployed.
- canonical MLB event identity from statsapi gamePk (mlb:gamepk:<pk>), with
event_identity_source/method/version recorded. The id is canonical; the
binding is derived and says so.
- IMPOSSIBLE-BINDING REFUSAL. Verified in prod 2026-08-26: Joe Mack (Marlins)
was bound to Dodgers@Braves and Yandy Diaz (Rays) to Rangers@WhiteSox, both
from one book in the 01:00/03:01 UTC cycles after their own games began. Root
cause is source market data, not the binder. A prop whose player's team is not
an event participant now refuses; unknown team preserves uncertainty.
- event-aware dedupe: books still collapse, events no longer do. An unresolved
MLB event fractures rather than falling back to the collision-prone
date+teams key.
- publication commit moved AFTER the authoritative Redis slate write, with
exact parity-gap identity when the product publishes and the record does not.
- lineage dual-write behind LINEAGE_CANARY_SPORTS, DISABLED for this deploy.
Excluded deliberately: WNBA feed/chain, market ontology, PerformanceDistribution,
calibration certification, truth diagnostics, applyRevision Phase-1, and the
analyzeViaEngine1 confidence-rounding change (a served field).
Suite 380/5,040/0 from this worktree; web tsc exit 0; champion output identical
to production.
