+# Bound retained-reader authorization database work
+
+## Measured problem
+
+A synthetic local service fixture uses 383 workspace paths and 64 retained runs
+with the same agent and responsible user. It exercises the production publication
+guard against disposable PostgreSQL. It does not represent a live tenant or a
+Product E2E evaluation.
+
+The original guard made 1,431 queries. A declared 4ms round-trip delay in a
+loopback proxy increased one admission to 15.19 seconds and three concurrent
+admissions to 54.69 seconds. The company root fence serializes those admissions.
+With this change, one admission makes 680 queries and takes 7.13 seconds under
+the same proxy; three take 20.93 seconds. The zero-injected-delay samples took
+359ms before and 146ms after. Timing samples are controlled local evidence, not
+an agent-response or hosted latency guarantee.
+
+## Change boundary
+
+Retained readers still need individual saved-run identity and execution-policy
+checks. Current readers still need the existing write checks. Existing company
+root fences, row locks, source privacy and publication ordering stay in place.
+
+Batch retained-reader project reads through the existing multi-actor read API.
+Share only database read promises within one call. Keep actor-supplied membership
+snapshots and per-actor privacy results separate. Key raw reads by their company,
+principal and run as applicable. Each later call reads current grants again.
+Select only the run identity and saved policy fields needed by the guard,
+including both native and legacy issue-binding fallbacks.
+
+## Verification and remaining proof
+
+The query-count regression must fail on the original code without changing its
+800-query bound. Distinct reader identities and stored policies must still fail
+closed. Grant revocation must affect the next call. Supplied membership snapshots
+must match individual decisions in both actor orders without leaking into database
+snapshots. Run the complete affected authorization and source-trust suites.
+
+Full repository typecheck and build plus fresh current-head CI and review precede
+merge. A real hosted warm agent reply remains the acceptance test for the separate
+under-30-second objective. Neither this service benchmark nor a fresh local
+provider run establishes that hosted result.
