## Summary: Remaining Gaps
|
||||
|
||||
### JetStream
|
||||
None in scope after this plan; all in-scope parity rows moved to `Y`.
|
||||
### Full Repo
|
||||
None in tracked scope after this plan; unresolved table rows were closed to `Y` with parity tests.
|
||||
|
||||
### Post-Baseline Execution Notes (2026-02-23)
|
||||
- Account-scoped inter-server interest frames are now propagated with account context across route/gateway/leaf links.
|
||||
- Gateway reply remap (`_GR_.`) and leaf loop marker handling (`$LDS.`) are enforced in transport paths.
|
||||
- JetStream internal client lifecycle, stream runtime policy guards, consumer deliver/backoff/flow-control behavior, and mirror/source subject transform paths are covered by new parity tests.
|
||||
- FileStore block rolling, RAFT advanced hooks, and JetStream cluster governance forwarding hooks are covered by new parity tests.
|
||||
- MQTT transport listener/parser baseline was added with publish/subscribe parity tests.

# Full-Repo Remaining Parity Design
|
||||
|
||||
**Date:** 2026-02-23
|
||||
**Status:** Approved
|
||||
**Scope:** Close all remaining `Baseline` / `N` / `Stub` rows in `differences.md` using strict behavioral parity criteria with test-backed evidence.
|
||||
|
||||
## 1. Architecture and Scope Boundary
|
||||
|
||||
### Parity control model
|
||||
Parity closure in this cycle uses a row-level truth matrix with three independent states per unresolved row:
|
||||
|
||||
1. Behavior
|
||||
- Go-contract behavior is implemented (not just helper hooks or placeholders).
|
||||
|
||||
2. Tests
|
||||
- Contract-positive and negative/edge tests exist and fail if behavior regresses to baseline.
|
||||
|
||||
3. Docs
|
||||
- `differences.md` row status matches verified behavior/test state.
|
||||
|
||||
Rows move to `Y` only when **Behavior + Tests + Docs** are all complete.
|
||||
|
||||
### Execution ordering
|
||||
1. Core protocol, transport, and sublist semantics.
|
||||
2. Auth and monitoring rows.
|
||||
3. JetStream runtime policy semantics.
|
||||
4. JetStream storage, RAFT, and JetStream clustering semantics.
|
||||
5. Documentation and evidence synchronization.
|
||||
|
||||
### Scope note
|
||||
This cycle intentionally covers full-repo unresolved rows, not JetStream-only, because remaining JetStream closure depends on transport/protocol/subscription/runtime correctness and docs currently contain summary/table inconsistencies.
|
||||
|
||||
## 2. Component Plan
|
||||
|
||||
### A. Protocol and transport parity
|
||||
Primary files:
|
||||
- `src/NATS.Server/NatsServer.cs`
|
||||
- `src/NATS.Server/NatsClient.cs`
|
||||
- `src/NATS.Server/Protocol/NatsParser.cs`
|
||||
- `src/NATS.Server/Protocol/ClientCommandMatrix.cs`
|
||||
- `src/NATS.Server/Routes/RouteConnection.cs`
|
||||
- `src/NATS.Server/Routes/RouteManager.cs`
|
||||
- `src/NATS.Server/Gateways/GatewayConnection.cs`
|
||||
- `src/NATS.Server/Gateways/GatewayManager.cs`
|
||||
- `src/NATS.Server/LeafNodes/LeafConnection.cs`
|
||||
- `src/NATS.Server/LeafNodes/LeafNodeManager.cs`
|
||||
|
||||
Target rows:
|
||||
- Inter-server op semantics and routing contracts still marked baseline or missing.
|
||||
- Gateway/leaf advanced semantics beyond handshake-level support.
|
||||
- Route/gateway/leaf account-aware interest and delivery behavior.
|
||||
|
||||
### B. SubList and subscription parity
|
||||
Primary files:
|
||||
- `src/NATS.Server/Subscriptions/SubList.cs`
|
||||
- `src/NATS.Server/Subscriptions/RemoteSubscription.cs`
|
||||
- `src/NATS.Server/Subscriptions/Subscription.cs`
|
||||
|
||||
Target rows:
|
||||
- Notification/interest-change hooks.
|
||||
- Local/remote filtering and queue-weight behavior.
|
||||
- `MatchBytes` and cache/fanout parity behavior.
|
||||
|
||||
### C. Auth and monitoring parity
|
||||
Primary files:
|
||||
- `src/NATS.Server/Auth/*`
|
||||
- `src/NATS.Server/Monitoring/ConnzHandler.cs`
|
||||
- `src/NATS.Server/Monitoring/VarzHandler.cs`
|
||||
- `src/NATS.Server/Monitoring/*` response models
|
||||
|
||||
Target rows:
|
||||
- Missing auth extension points (custom/external/proxy).
|
||||
- Remaining `connz`/`varz` filters and fields.
|
||||
|
||||
### D. JetStream runtime parity
|
||||
Primary files:
|
||||
- `src/NATS.Server/JetStream/StreamManager.cs`
|
||||
- `src/NATS.Server/JetStream/ConsumerManager.cs`
|
||||
- `src/NATS.Server/JetStream/Consumers/*`
|
||||
- `src/NATS.Server/JetStream/Publish/*`
|
||||
- `src/NATS.Server/JetStream/Api/Handlers/*`
|
||||
- `src/NATS.Server/JetStream/Validation/JetStreamConfigValidator.cs`
|
||||
|
||||
Target rows:
|
||||
- Stream retention/maxage/maxmsgsper/maxmsgsize and stream feature toggles.
|
||||
- Consumer ack/backoff/delivery/replay/flow/rate semantics.
|
||||
- Mirror/source advanced behavior and cross-account semantics.
|
||||
|
||||
### E. Storage, RAFT, and JetStream cluster parity
|
||||
Primary files:
|
||||
- `src/NATS.Server/JetStream/Storage/*`
|
||||
- `src/NATS.Server/Raft/*`
|
||||
- `src/NATS.Server/JetStream/Cluster/*`
|
||||
- `src/NATS.Server/NatsServer.cs` integration points
|
||||
|
||||
Target rows:
|
||||
- FileStore behavior gaps (layout/index/ttl/compression/encryption).
|
||||
- RAFT behavior gaps (heartbeat/next-index/snapshot transfer/membership/transport semantics).
|
||||
- JetStream meta-group and replica-group behavioral gaps.
|
||||
|
||||
### F. Evidence and documentation parity
|
||||
Primary files:
|
||||
- `differences.md`
|
||||
- `docs/plans/2026-02-23-jetstream-remaining-parity-map.md`
|
||||
- `docs/plans/2026-02-23-jetstream-remaining-parity-verification.md`
|
||||
|
||||
Target:
|
||||
- Remove summary/table drift and keep row status tied to behavior and tests.
|
||||
|
||||
## 3. Data Flow and Behavioral Contracts
|
||||
|
||||
1. Truth-matrix contract
|
||||
- Every unresolved row is tracked as Behavior/Test/Docs until closure.
|
||||
- Summary statements never override unresolved table rows.
|
||||
|
||||
2. Transport contract
|
||||
- Inter-server propagation preserves account scope and message semantics end-to-end.
|
||||
- Remote delivery resolves against correct account state, not global-only shortcuts.
|
||||
- Gateway reply remap and leaf loop markers stay transparent to client-visible semantics.
|
||||
|
||||
3. SubList contract
|
||||
- Local interest and remote interest behavior are explicitly separated and account-aware.
|
||||
- Queue weights and remote subscriptions influence deterministic routing decisions.
|
||||
- Cache and match behavior remain correct under concurrent mutate/read operations.
|
||||
|
||||
4. Auth and monitoring contract
|
||||
- New auth extension points must preserve existing permission and revocation safety.
|
||||
- `connz`/`varz` parity fields reflect live data and match expected filter/sort semantics.
|
||||
|
||||
5. JetStream runtime contract
|
||||
- Stream policy semantics are enforced in runtime operations, not only parse-time.
|
||||
- Consumer state transitions are deterministic across pull/push and redelivery flows.
|
||||
- Mirror/source behavior includes mapping and cross-account rules.
|
||||
|
||||
6. Storage/RAFT/cluster contract
|
||||
- Store recovery and TTL/index semantics are deterministic.
|
||||
- RAFT behavior is consensus-driven (not placeholder-only hooks).
|
||||
- JetStream cluster governance behavior depends on effective state transitions.
|
||||
|
||||
## 4. Error Handling, Test Strategy, and Completion Criteria
|
||||
|
||||
### Error handling
|
||||
1. Preserve protocol-specific and JetStream-specific error contracts.
|
||||
2. Fail closed on remap/loop/account-authorization anomalies.
|
||||
3. Avoid partial state mutation on cross-node failures.
|
||||
|
||||
### Test strategy
|
||||
1. Each unresolved row gets positive + negative/edge coverage.
|
||||
2. Multi-node/network semantics require integration tests, not helper-only tests.
|
||||
3. Parity closure tests must inspect unresolved row status and supporting evidence, not only summary text.
|
||||
|
||||
### Completion criteria
|
||||
1. All in-scope unresolved rows are either:
|
||||
- moved to `Y` with evidence, or
|
||||
- explicitly blocked with concrete technical rationale and failing evidence.
|
||||
2. Focused suites pass for protocol/transport/sublist/auth/monitoring/jetstream/raft layers.
|
||||
3. Full suite passes:
|
||||
- `dotnet test -v minimal`
|
||||
4. `differences.md`, parity map, and verification report are synchronized to actual behavior and tests.

# Full-Repo Remaining Parity Implementation Plan
|
||||
|
||||
> **For Codex:** REQUIRED SUB-SKILL: Use `executeplan` to implement this plan task-by-task.
|
||||
|
||||
**Goal:** Close every currently unresolved `Baseline` / `N` / `Stub` parity row in `differences.md` with strict behavior-level parity and test-backed evidence.
|
||||
|
||||
**Architecture:** Use a truth-matrix workflow where each unresolved row is tracked by behavior, test, and docs state. Implement dependencies in layers: core server/protocol/sublist first, then auth/monitoring, then JetStream runtime/storage/RAFT/clustering, then docs synchronization. Rows move to `Y` only when behavior is implemented and validated by meaningful contract tests.
|
||||
|
||||
**Tech Stack:** .NET 10, C# 14, xUnit 3, Shouldly, ASP.NET Core minimal APIs, System.IO.Pipelines, System.Buffers, System.Text.Json.
|
||||
|
||||
---
|
||||
|
||||
**Execution guardrails**
|
||||
- Use `@test-driven-development` for every task.
|
||||
- If behavior diverges from protocol/runtime expectations, switch to `@systematic-debugging` before code changes.
|
||||
- Keep one commit per task.
|
||||
- Run `@verification-before-completion` before final status updates.
|
||||
|
||||
### Task 1: Add Truth-Matrix Parity Guard and Fix Summary/Table Drift Detection

||||
|
||||
Run: `dotnet test tests/NATS.Server.Tests --filter "FullyQualifiedName~AcceptLoopReloadLockTests|FullyQualifiedName~AcceptLoopErrorCallbackTests" -v minimal`

|
||||
|
||||
Run: `dotnet test tests/NATS.Server.Tests --filter "FullyQualifiedName~AdaptiveReadBufferTests|FullyQualifiedName~OutboundBufferPoolTests" -v minimal`
|
||||
Expected: FAIL because no adaptive model or 3-tier pool exists.
|
||||
|
||||
**Step 3: Write minimal implementation**
|
||||
|
||||
```csharp
|
||||
public int CurrentSize => Math.Clamp(_target, 512, 64 * 1024);
|
||||
public IMemoryOwner<byte> Rent(int size) => size <= 512 ? _small.Rent(512) : size <= 4096 ? _medium.Rent(4096) : _large.Rent(64 * 1024);

|
||||
|
||||
**Step 3: Write minimal implementation**
|
||||
|
