Phase 5 (plan §7): the entire integration suite passes with the RLS
policies live. The suite was the triage enumerator the plan predicted:
- device_auth middleware: the THIRD identity bridge — KOReader/Kobo
device-authenticated requests read media as the DEVICE OWNER
(plan A9 called this path out; the flip was 404s on sync metadata).
- conflicts/analytics/progress handlers: detached
context.Background() reads threaded to the request context (the
requesting user's identity) — 12+ sites; resolve helpers take ctx.
- scanner: ScanFolders self-declares its configured admin identity
(server maintenance, product-correct for any caller); generic job
creation stamps the requesting admin.
- harness: setup.DBPool and the sync-test pool declare
rls.SeedIdentity at SESSION scope via BeforeAcquire — the pool never
serves a second identity, so no A3 bleed; setup.DB falls back to the
seed identity (NewSeedDB) for ungoverned-context calls; filter tests
use seedExec for raw governed-table statements.
- contract pin WIDENED (docs/contract_pins.md 2026-10-29): under RLS,
item-scoped gates may answer 404 (row invisible — no existence leak)
as well as 403 (Go-level checks on listings keep strict 403).
- TestWorker_JobStatusTracking — the pre-existing red from the Phase 0
baseline — passes with the harness seed work; no product change.
