 P5-00 is required. Resolve these narrowly against the **existing** shell first, with regression evidence before regrouping or restyling it. This separates baseline remediation from redesign regressions.

-The remaining acceptance condition is **P5-00-D01**, an unrelated pre-existing backend test that now fails because its fixed fixture dates are evaluated against the real clock. The complete backend result is 915/916, not the inherited 916 passing. Restore that test's deterministic clock in a separately authorized test-only correction and rerun all 916 before starting P5-01. This checkpoint does not grant an exception to the baseline gate. F04 remains an independent production gate; package, CV and later-slice gates are unchanged. **P5-01 and B07 were not begun.**
+P5-00-D01 was closed on 2026-09-21 by injecting the test's existing `MutableTimeProvider(FixedNow)` into the rules worker.

 On 2026-09-20 and again in the final 2026-09-21 run, the unchanged `BackgroundWorkerTenantTests.Rules_worker_uses_each_owners_settings_and_is_idempotent` fails at line 79: expected `Applied`, actual `Ghosted`. Its fixture seeds `DateApplied = FixedNow.AddDays(-30)` (2026-07-16), but the rules worker receives `TimeProvider.System`. The real clock has crossed the second owner's 60-day threshold. The production worker is applying that configured rule; this test mixes fixed data and a moving clock.
 
-All 916 backend tests were executed: **915 passed, one failed, none skipped**. Neither backend application code nor this test was changed. This is distinct from P2-D01, SQLite write contention and a P5-00 UI regression. A requested, separate one-line test-only correction would pass the already existing `MutableTimeProvider(FixedNow)` to this worker and then rerun all 916; no production clock/rule change is proposed. Until that correction is authorized and validated, the inherited all-green backend baseline is not restored. Do not waive, filter out or relabel this test as expected failure.
+The original P5-00 checkpoint executed all 916 tests: 915 passed, one failed, none skipped. The follow-up prerequisite checkpoint changed only this test to pass the already existing `MutableTimeProvider(FixedNow)` to the worker. The rerun passed **916/916** in 19 seconds. Production code, rules and schedules are unchanged; no skip or expected-failure annotation was added. This is distinct from P2-D01, SQLite write contention and the remaining P5-00-D02 Jobs browser-Back focus debt.
 
 An earlier overlapping API/build attempt encountered Windows apphost file locking. Runs were subsequently serialized. That tooling conflict is not the cause of the assertion above. The interrupted browser run was replaced by a complete final run, not combined into a fabricated aggregate.

 - **P5-00-D02 — open Jobs browser-Back focus debt:** after the workspace actually renders, browser Back preserves the query but does not restore row focus. The explicit workspace Back button carries the existing focus contract. Corrected browser evidence distinguishes them; no application behavior changed.
