 **Core value:** An existing WinterCMS-shaped app can be ported plugin by plugin to a single Go binary without its frontend noticing: the PHP version's API contract is the acceptance test.

@@ -83,6 +84,9 @@ Recent decisions affecting current work:
 - [Phase 02]: Fresh PHP self-replay uses disposable MariaDB fonoteka_parity_* plus process-local hex credentials, never the developer DB or caller-supplied PHP_PARITY_TARGET — T-02-01 T-02-05: check-phase2.sh --fresh-php owns the origin and rejects PHP_PARITY_TARGET
 - [Phase 02]: Client flows run on a second winter:up after dropping tables so they are not replayed after the mutating 154-route suite — D-16 and 02-03 seed-then-clients: keep route replay and Nuxt/MCP replay on disjoint schemas
 - [Phase 02]: Capture-by-reference mismatch is a two-step share:item flow with a live token change on the second /show — D-11 D-13: contract tests exercise RecordFlow/ReplayFlow public APIs, not private helpers
+- [Phase 03]: GORM and app services share one pgx-stdlib *sql.DB; the River LISTEN/NOTIFY pool is a Phase 11 seam and is not created in lagoon.Open — DATA-01: one shared pool now; dual-driver River listener deferred
+- [Phase 03]: Generated app main stays framework-generic (lagoon.RuntimeCommands + surf.ServeCommand); fonoteka.go/app.Handler is the in-process boot seam for parity tests — summer build cannot import the app package; CLI serve and tests still assemble the same surf router
+- [Phase 03]: Empty golem15.user.jwt.secret fails Boot; tests use a fixed test-only HS256 secret and do not issue tokens through a production API — D-11: missing secret must not fall back; token minting stays out of Phase 3
