 ## Decisions & Risks
 - CAS remediation window (≤3 days for Critical/High) running under signed waiver; track SIGNALS-24-002/004/005 for compliance.
 - Callgraph CAS bucket promotion and signed manifests remain outstanding for SIGNALS-24-002; risk to scoring start if delayed.
-- Runtime facts provenance/context enrichment and scoring linkage pending (SIGNALS-24-003); downstream scoring (24-004/005) can start only after completion.
+- SIGNALS-24-003 now blocked on CAS promotion/provenance schema; downstream scoring (24-004/005) depend on this landing.
 - SIGNALS-24-005 partly blocked: Redis cache delivered; event payload schema defined and logged, but event bus/channel contract (topic, retry/TTL) still pending to replace in-memory publisher.
-- Tests for Signals unit suite are now green; full Signals solution test run started—monitor to completion for coverage of new cache/event wiring.
-- Full Signals solution restore/test still exceeding 60s and cancelled for time; rerun needed with warmed restore cache or extended execution window.
+- Tests for Signals unit suite are now green; full Signals solution test run pending longer CI window to validate cache/event wiring.
 
 ## Next Checkpoints
 - Schedule CAS waiver review before 2025-11-20 to confirm remediation progress for SIGNALS-24-002/004/005.
