```
cargo test --manifest-path tidal/Cargo.toml --test m9_leave_revocation --features test-utils

running 8 tests
test status_query_lifecycle ... ok
test leave_is_idempotent ... ok
test unknown_user_defaults_to_active ... ok
test left_at_ns_preserved_on_rejoin ... ok
test join_resumes_cohort_fanout ... ok
test leave_stops_cohort_fanout ... ok
test leave_stops_community_forwarding ... ok
test durability_across_reopen ... ok

test result: ok. 8 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out; finished in 5.38s
```

All 8 integration tests pass including the durability-across-reopen test (TC-06).

### Unit Tests: entities::community (membership serde)

Covered within lib test suite. All 6 serde unit tests pass:
- `serde_active_roundtrip`
- `serde_left_with_timestamp_roundtrip`
- `deserialize_rejects_short_slice`
- `deserialize_rejects_invalid_status_byte`
- `active_has_zero_left_at_ns_in_wire`
- `default_active_is_active`

### Full Lib Test Suite

```
cargo test --manifest-path tidal/Cargo.toml --lib --quiet

test result: ok. 1299 passed; 0 failed; 0 ignored; 0 measured; 0 filtered out; finished in 12.02s
```

No regressions. Count is at or above pre-feature baseline.

### Regression: m6_cohort Integration Suite

All cohort tests pass. The leave gate does not affect users without a leave record (the default Active path).
