 ## Accumulated Context
 
@@ -96,6 +97,9 @@ Recent decisions affecting current work:
 - [Phase 03]: A ported route with a trusted seed_hook skips the global PHP bootstrap replay — D-20: unported register/login and POST genres; the hook mints a test-only JWT
 - [Phase 03]: Corpus passing increments only after the ported subtest succeeds; pending never counts as passing — QA-04 T-03-06: 154 recorded, 1 passing, 153 pending
 - [Phase 03]: Colliding fixture IDs are derived from CanonicalGenres seed order (rock=1, electronic=2, jazz=4) — D-20: set id:token, id:wishlist-album, id:genre from PHP seed order, not user input
+- [Phase 03]: Phase 3 gate inlines TestParitySynthetic and CLI record/replay; PHP --fresh-php stays the Phase 2 sign-off because four wishlist album_count routes currently fail on live PHP — check-phase2.sh --fresh-php reports 150/154 on wishlist album_count expected 1 vs live 2. Phase 3 did not change PHP, tide, or those fixtures, so the Phase 3 gate must not fail on that drift.
+- [Phase 03]: testcontainers-go v0.44.0 is the STACK-named test dependency for framework lagoon isolation tests, matching the app TestMain — DATA-01 isolation tests need a real ICU pl-PL Postgres. The app already used testcontainers; the framework module now pins the same STACK versions so lagoon tests do not share the app TestMain.
+- [Phase 03]: High-severity T-03-01 through T-03-04 and T-03-06 are closed with failing-when-broken tests; token issuing remains test-only until Phase 7 — Roadmap required a security review of the JWT guard. 03-SECURITY-REVIEW.md maps each threat to a passing test; minting tokens through a production API is out of this slice.
