# Deferred Features Implementation Design
|
||||
|
||||
**Date**: 2026-03-01
|
||||
**Status**: Draft
|
||||
**Scope**: 363 deferred features + 1 stub across 6 batches
|
||||
|
||||
## Context
|
||||
|
||||
After completing batches 16-41, 363 features remain deferred (plus 1 stub). These were deferred because they require server runtime infrastructure — event dispatch loops, HTTP monitoring endpoints, MQTT session management, and account resolver dispatch.
|
||||
|
||||
Current state: 82.0% complete (5694/6942 items). This work targets bringing features to ~92% (all 363 + 1 stub → verified).
|
||||
|
||||
884 deferred tests (mostly integration/cluster tests) are out of scope — they remain deferred for a future integration testing phase.
|
||||
|
||||
## Decisions
|
||||
|
||||
- **Implementation depth**: Full method bodies ported from Go to idiomatic C#. Methods will be functionally correct and will work once server runtime boots, but won't be exercised by tests yet.
|
||||
- **Tests**: No new unit tests for these features. All 884 deferred tests remain deferred.
|
||||
- **Execution**: Parallel Claude Code Sonnet agents with `isolation: "worktree"`, 2-3 concurrent.
|
||||
- **PortTracker updates**: Run audit after each batch merge to promote features to verified.
|
||||
|
||||

|
||||
- Feature 2962: `scheduler.go:getScheduledMessages` — currently stub, implement fully
|
||||
|
||||
## Execution Plan
|
||||
|
||||
### Wave 1 (parallel)
|
||||
- **Batch 42** (Foundation Helpers, 54 features)
|
||||
- **Batch 43** (Accounts, 37 features)
|
||||
|
||||
### Wave 2 (parallel, after Wave 1)
|
||||
- **Batch 44** (Events Core, 46 features)
|
||||
- **Batch 46** (Monitor Endpoints, 45 features)
|
||||
|
||||
### Wave 3 (after Batch 44)
|
||||
- **Batch 45** (Events Server, 42 features)
|
||||
|
||||
### Wave 4 (after Batch 45)
|
||||
- **Batch 47** (MQTT Runtime, 139 features)
|
||||
|
||||
## Post-Execution
|
||||
|
||||
After all batches merge:
|
||||
1. Run `dotnet build dotnet/` to confirm compilation
|
||||
2. Run `dotnet test dotnet/tests/ZB.MOM.NatsNet.Server.Tests/` to confirm no regressions
|
||||
3. Reset deferred→unknown in porting.db, re-run audit
|
||||
4. Generate final report
|
||||
|
||||
## Expected Outcome
|
||||
|
||||
- Features: 3263 + 363 + 1 = 3627 verified (vs 3673 total = 98.7%)
|
||||
- Remaining: 22 complete, 24 n/a = stable
|
||||
- Tests: 2066 verified + audit promotions (deferred integration tests remain)

# Deferred Features Implementation Plan
|
||||
|
||||
> **For Claude:** REQUIRED SUB-SKILL: Use superpowers-extended-cc:executing-plans to implement this plan task-by-task.
|
||||
|
||||
**Goal:** Implement 363 deferred features + 1 stub across 6 batches to bring feature coverage from 82% to ~92%.
|
||||
|
||||
**Architecture:** Each batch runs as a parallel Claude Code Sonnet agent in an isolated git worktree. Agents port full method bodies from Go to idiomatic C#. After each batch merges to main, run PortTracker audit to promote features to verified.
|
||||
|
||||
**Tech Stack:** .NET 10, C# latest, xUnit 3 + Shouldly + NSubstitute (testing standards but no new tests in this phase)
|
||||
|
||||
---
|
||||
|
||||
## Execution Model
|
||||
|
||||
Each batch is dispatched as an Agent tool call with `model: "sonnet"` and `isolation: "worktree"`. The agent receives a self-contained prompt with all context needed to implement the batch independently. After the agent completes, its worktree changes are merged to main.
|
||||
|
||||
**Wave 1 (parallel):** Batches 42 + 43
|
||||
**Wave 2 (parallel, after Wave 1):** Batches 44 + 46
|
||||
**Wave 3 (after Batch 44):** Batch 45
|
||||
**Wave 4 (after Batch 45):** Batch 47
|
||||
|
||||
### Merge Protocol (after each batch)
|
||||
|
||||
```bash
|
||||
cd <worktree-path>
|
||||
git add -A && git commit -m "feat(batch<N>): <description>"
|
||||
# Back in main:
|
||||
git merge <worktree-branch> --no-edit
|
||||
# If porting.db conflicts: git checkout --ours porting.db
|
||||
# Run: dotnet build dotnet/
|
||||
# Run: dotnet test dotnet/tests/ZB.MOM.NatsNet.Server.Tests/ -q
|
||||
# Run audit: dotnet run --project tools/NatsNet.PortTracker -- audit --type all --db porting.db --execute
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Shared Coding Standards (included in every batch prompt)
|
||||
|
||||
All agents must follow these rules:
|
||||
|
||||
1. **.NET 10, C# latest** — file-scoped namespaces, nullable enabled, implicit usings
|
||||
2. **Naming**: PascalCase for public members, `_camelCase` for private fields
|
||||
3. **Namespace**: `ZB.MOM.NatsNet.Server` (or `.Internal`, `.Mqtt` for MQTT-specific code)
|
||||
4. **Go→.NET patterns**:
|
||||
- `sync.RWMutex` → `ReaderWriterLockSlim`
|
||||
- `sync.Mutex` → `Lock` (C# 13)
|
||||
- `atomic.Int64` → `Interlocked.Read/Exchange/Add` on `long`
|
||||
- `chan struct{}` → `Channel<bool>` or `CancellationTokenSource`
|
||||
- `time.Duration` → `TimeSpan`
|
||||
- `goroutine + ticker` → `System.Threading.Timer`
|
||||
5. **Do NOT** use FluentAssertions or Moq
|
||||
6. **Do NOT** write new unit tests — implement features only
|
||||
7. **Do NOT** modify porting.db — it will be reconciled after merge
|
||||
8. **Do NOT** switch branches or merge — work only in the worktree branch
|
||||
9. **Read the Go source** for each method before porting — use: `cat golang/nats-server/<file> | head -n <end> | tail -n <count>`
|
||||
10. **Build gate**: `dotnet build dotnet/` must pass after all changes
|
||||
11. **Test gate**: `dotnet test dotnet/tests/ZB.MOM.NatsNet.Server.Tests/ -q` must show 0 failures
|
||||
12. **Commit** all changes with a single commit at the end

||||

## Features to Implement
|
||||
|
||||
### Group A: MsgTrace (28 features)
|
||||
|
||||
Create `MessageTrace/MsgTrace.cs` with a `MsgTrace` class that implements the trace event pipeline. Port these methods from `server/msgtrace.go`:
|
||||
|
||||
Feature IDs and methods:

|
||||
|
||||
### Group C: Monitor Helpers (25 features)
|
||||
|
||||

|
||||
|
||||
### Group D: Scheduler Stub (1 feature)
|
||||
|
||||
- 2962: MsgScheduling.getScheduledMessages — replace the stub comment in `Internal/MsgScheduling.cs` (around line 201) with the full implementation. Read `golang/nats-server/server/scheduler.go` lines 158-244 for the Go source. This method takes two loader delegates (loadMsg and loadLast), iterates expired schedules, validates headers, strips schedule-specific headers, adds new headers, and returns sorted InMsg list.
|
||||
|
||||
## Build Verification
|
||||
|
||||
After all changes:
|
||||
```bash
|
||||
dotnet build dotnet/
|
||||
dotnet test dotnet/tests/ZB.MOM.NatsNet.Server.Tests/ -q
|
||||
```
|
||||
|
||||
Both must pass with 0 failures.
|
||||
|
||||

|
||||
|
||||
```bash
|
||||
git add -A
|
||||
git commit -m "feat(batch42): implement foundation helpers — msgtrace, monitor helpers, scheduler"

|
||||
|
||||
### Agent Prompt
|
||||
|
||||
~~~
|
||||
IMPORTANT: Before doing anything else, read the file AGENTS.md in the project root for full project context, build/test commands, and coding standards.
|
||||
|
||||
You are implementing Batch 47: MQTT Full Runtime — 139 deferred features covering the complete MQTT protocol implementation including JetStream API bridge, session management, account session management, server-side handlers, and client-side protocol parsing.
|
||||
|
||||
This is the largest batch. Organize your work into logical sub-groups and implement methodically.
|
||||
|
||||
IMPORTANT: This batch depends on Batches 44+45 (Events). The event dispatch infrastructure (sendInternalMsg, sysSubscribe, etc.) should already exist. Read `NatsServer.Events.cs` to understand the dispatch pattern.
|
||||
|
||||
## Go Source Files to Read
|
||||
|
||||
- `golang/nats-server/server/mqtt.go` (5882 lines) — complete MQTT implementation
|
||||
|
||||
## Existing .NET Files to Read First
|
||||
|
||||
- `dotnet/src/ZB.MOM.NatsNet.Server/Mqtt/MqttTypes.cs` — existing MQTT types (MqttWill, MqttConnectProto, MqttSession type def, etc.)
|
||||
- `dotnet/src/ZB.MOM.NatsNet.Server/Mqtt/MqttConstants.cs` — packet types, flags, constants
|
||||
- `dotnet/src/ZB.MOM.NatsNet.Server/Mqtt/MqttHandler.cs` — per-client MQTT state
|
||||
- `dotnet/src/ZB.MOM.NatsNet.Server/Mqtt/MqttReader.cs` — byte stream parser
|
||||
- `dotnet/src/ZB.MOM.NatsNet.Server/Mqtt/MqttWriter.cs` — byte stream builder
|
||||
- `dotnet/src/ZB.MOM.NatsNet.Server/Mqtt/MqttSubjectConverter.cs` — topic/subject conversion
|
||||
- `dotnet/src/ZB.MOM.NatsNet.Server/NatsServer.cs` — server fields
|
||||
- `dotnet/src/ZB.MOM.NatsNet.Server/ClientConnection.cs` — client connection
|
||||

## Task 7: Post-Merge Reconciliation
|
||||
|
||||
After all 6 batches merge to main:
|

**Step 1: Build and test**
|
||||
```bash
|
||||
dotnet build dotnet/
|
||||
dotnet test dotnet/tests/ZB.MOM.NatsNet.Server.Tests/ -q
|
||||
```
|
||||
|
||||
**Step 2: Reset deferred features and re-audit**
|
||||
```bash
|
||||
sqlite3 porting.db "UPDATE features SET status='unknown' WHERE status='deferred';"
|
||||
sqlite3 porting.db "UPDATE features SET status='unknown' WHERE status='stub';"
|
||||
dotnet run --project tools/NatsNet.PortTracker -- audit --type all --db porting.db --execute
|
||||
```
|
||||
|
||||
**Step 3: Generate report**
|
||||
```bash
|
||||
./reports/generate-report.sh
|
||||
```
|
||||
|
||||
**Step 4: Commit reconciliation**
|
||||
```bash
|
||||
git add porting.db
|
||||
git add -f reports/current.md
|
||||
git commit -m "chore: reconcile porting.db after deferred features batches 42-47"
|
||||
```
|
||||
|
||||
**Expected outcome**: 363+ features promoted from deferred→verified, bringing total to ~98% feature coverage.
