### Remaining Lower Priority
1. **Dynamic buffer sizing** — delegated to Pipe, less optimized for long-lived connections

## 10. JetStream Remaining Parity (2026-02-23)
### Newly Ported API Families
- `$JS.API.INFO`
- `$JS.API.STREAM.UPDATE.*`, `$JS.API.STREAM.DELETE.*`, `$JS.API.STREAM.NAMES`, `$JS.API.STREAM.LIST`
- `$JS.API.STREAM.MSG.GET.*`, `$JS.API.STREAM.MSG.DELETE.*`, `$JS.API.STREAM.PURGE.*`
- `$JS.API.DIRECT.GET.*`
- `$JS.API.STREAM.SNAPSHOT.*`, `$JS.API.STREAM.RESTORE.*`
- `$JS.API.CONSUMER.NAMES.*`, `$JS.API.CONSUMER.LIST.*`, `$JS.API.CONSUMER.DELETE.*.*`
- `$JS.API.CONSUMER.PAUSE.*.*`, `$JS.API.CONSUMER.RESET.*.*`, `$JS.API.CONSUMER.UNPIN.*.*`
- `$JS.API.CONSUMER.MSG.NEXT.*.*`
- `$JS.API.STREAM.LEADER.STEPDOWN.*`, `$JS.API.META.LEADER.STEPDOWN`
### Runtime/Storage/RAFT Parity Additions
- JetStream publish precondition support for expected last sequence (`ErrorCode=10071` on mismatch).
- Pull consumer `no_wait` contract support (`TimedOut=false` on immediate empty fetch).
- Ack-all pending floor behavior via `AckProcessor.AckAll` and pending-count introspection.
- Stream store subject index support (`LoadLastBySubjectAsync`) in `MemStore` and `FileStore`.
- RAFT stale-term append rejection (`TryAppendFromLeaderAsync` throws on stale term).
- `/jsz` and `/varz` now expose JetStream API totals/errors from server stats.
### Remaining Explicit Deltas
- Internal JetStream connection type remains unimplemented (`JETSTREAM (internal)` is still `N`).
- Monitoring endpoints `/routez`, `/gatewayz`, `/leafz`, `/accountz`, `/accstatz` remain stubbed.
