Phase 3 of the RLS plan, pinned mid-flight because a parallel writer
was actively editing cmd/server/tests/rls_visibility_test.go (A14):
the file flip-flopped between two implementations and gained a compile
error after the previous commit. This snapshot makes the whole tree
compile; functional verification (two-boot gate, invariant green,
full suite) lands in the next commit(s).
- internal/rls: typed ctx keys — user identity (bridged from echo by
the router) and an INTERNAL marker whose semantics grant nothing:
no GUC is declared, so policy'd tables still raise at the engine;
only RLS-ungoverned tables (system_settings, users counts) work for
user-less startup paths (settings registry Load, CountAdmins).
- internal/database/scoped.go: DBTX decorator — per-statement tx,
commit-on-Close (:many) / commit-on-Scan (:one), error paths always
terminate the tx, refusal before SQL when no identity and not
internal.
- database/schema/schema.sql: idempotent policy block (DROP IF EXISTS
+ CREATE — schema.sql re-runs every boot): ENABLE + FORCE, read
policy exactly mirroring COALESCE(is_visible,true), permissive
per-command write stand-ins (FOR ALL would OR into SELECT).
- router.go: RLS bridge at BOTH c.Set("user") sites (JWT + device
auth) — echo-local storage never reaches the stdlib ctx.
- main.go + test harness: database.New over ScopedDB at both wiring
sites; startup reads use rls.WithInternal.
