- E-03: the open wrapper's handler-exit teardown no longer discards
UnknownChannel silently — debug log + benign-race pinning comment
(ledger take is the atomic gate; no double-decrement)
- E-04: consumer-facing doc note on the 64-parked-chunks observable
bound (channel-client.md + EARLY_ARRIVAL_CAP const doc) for
tunnel-style push-first producers
- N-2: ChannelManager::early_arrival_count() accessor (the
observability choice over removing the write-only counter),
documented monotonic, with a park/adopt-drain monotonicity test
- review 006: Unit 3 marked implemented in Status and remediation plan
Verification: 617 tests pass; clippy -D warnings clean (host +
wasm32 check); fmt clean; doc clean
