Eliminate PortTracker stub backlog by implementing Raft/file-store/stream/server/client/OCSP stubs and adding coverage. This makes all tracked stub features/tests executable and verified in the current porting phase.

Add SubscriptionIndex factory methods, notification wrappers, and
ValidateMapping. Implement 24 MemStore methods (TTL, scheduling, SDM,
age-check, purge/compact/reset) with JetStream header helpers and
constants. Verified features: 987 → 1026.

+## Project Summary
+
+This project ports the NATS messaging server from Go to .NET 10 C#. The Go source (~130K LOC) is the reference at `golang/nats-server/`. Porting progress is tracked in an SQLite database (`porting.db`) managed by the PortTracker CLI tool.

+## Build and Test
+
+```bash
+# Build the solution
+dotnet build dotnet/
+
+# Run all unit tests
+dotnet test dotnet/tests/ZB.MOM.NatsNet.Server.Tests/
+
+# Run filtered tests (by namespace/class)
+dotnet test --filter "FullyQualifiedName~ZB.MOM.NatsNet.Server.Tests.Protocol" \
+  dotnet/tests/ZB.MOM.NatsNet.Server.Tests/
+
+# Run integration tests
+dotnet test dotnet/tests/ZB.MOM.NatsNet.Server.IntegrationTests/
+
+# Generate porting report
+./reports/generate-report.sh
+```
+
+## .NET Coding Standards
+
+**MUST follow all rules in `docs/standards/dotnet-standards.md`.**
+
+Critical rules (non-negotiable):
+
+- .NET 10, C# latest, nullable enabled
+- **xUnit 3** + **Shouldly** + **NSubstitute** for testing
+- **NEVER use FluentAssertions or Moq** — these are forbidden
+- PascalCase for public members, `_camelCase` for private fields
+- File-scoped namespaces: `ZB.MOM.NatsNet.Server.[Module]`
+- Use `CancellationToken` on all async signatures
+- Use `ReadOnlySpan<byte>` on hot paths
+- Test naming: `[Method]_[Scenario]_[Expected]`
+- Test class naming: `[ClassName]Tests`
+- Structured logging with `ILogger<T>` and `LogContext.PushProperty`
+
+## PortTracker CLI
+
+All tracking commands use this base:
+
+```bash
+dotnet run --project tools/NatsNet.PortTracker -- <command> --db porting.db
+```
+
+### Querying
+
+| Command | Purpose |
+|---------|---------|
+| `report summary` | Show overall porting progress |
+| `dependency ready` | List items ready to port (no unported deps) |
+| `dependency blocked` | List items blocked by unported deps |
+| `feature list --status <s>` | List features by status |
+| `feature list --module <id>` | List features in a module |
+| `feature show <id>` | Show feature details (Go source path, .NET target) |
+| `test list --status <s>` | List tests by status |
+| `test show <id>` | Show test details |
+| `module list` | List all modules |
+| `module show <id>` | Show module with its features and tests |
+
+### Updating Status
+
+| Command | Purpose |
+|---------|---------|
+| `feature update <id> --status <s>` | Update one feature |
+| `feature batch-update --ids "1-10" --set-status <s> --execute` | Bulk update features |
+| `test update <id> --status <s>` | Update one test |
+| `test batch-update --ids "1-10" --set-status <s> --execute` | Bulk update tests |
+| `module update <id> --status <s>` | Update module status |
+
+### Audit Verification
+
+Status updates are verified against Roslyn audit results. If the audit disagrees with your requested status, add `--override "reason"` to force it.
+
+```bash
+feature update 42 --status verified --override "manually verified logic"
+```
+
+### Audit Commands
+
+| Command | Purpose |
+|---------|---------|
+| `audit --type features` | Dry-run audit of features against .NET source |
+| `audit --type tests` | Dry-run audit of tests against test project |
+| `audit --type features --execute` | Apply audit classifications to DB |
+| `audit --type tests --execute` | Apply test audit classifications to DB |
+
+### Valid Statuses
+
+```
+not_started → stub → complete → verified
+                 └→ n_a (not applicable)
+                 └→ deferred (blocked, needs server infra)
+```
+
+### Batch ID Syntax
+
+`--ids` accepts: ranges `"100-200"`, lists `"1,5,10"`, or mixed `"1-5,10,20-25"`.
+
+All batch commands default to dry-run. Add `--execute` to apply.
+
+## Porting Workflow
+
+### Finding Work
+
+1. Query for features ready to port:
+
+```bash
+dotnet run --project tools/NatsNet.PortTracker -- dependency ready --db porting.db
+```
+
+2. Or find deferred/stub features in a specific module:
+
+```bash
+dotnet run --project tools/NatsNet.PortTracker -- feature list --module <id> --status deferred --db porting.db
+```
+
+3. To find tests that need implementing:
+
+```bash
+dotnet run --project tools/NatsNet.PortTracker -- test list --status stub --db porting.db
+dotnet run --project tools/NatsNet.PortTracker -- test list --status deferred --db porting.db
+```
+
+### Implementing a Feature
+
+1. **Claim it** — mark as stub before starting:
+
+```bash
+dotnet run --project tools/NatsNet.PortTracker -- feature update <id> --status stub --db porting.db
+```
+
+2. **Read the Go source** — use `feature show <id>` to get the Go file path and line numbers, then read the Go implementation.
+
+3. **Write idiomatic C#** — translate intent, not lines:
+   - Use `async`/`await`, not goroutine translations
+   - Use `Channel<T>` for Go channels
+   - Use `CancellationToken` for `context.Context`
+   - Use `ReadOnlySpan<byte>` on hot paths
+   - Use `Lock` (C# 13) for `sync.Mutex`
+   - Use `ReaderWriterLockSlim` for `sync.RWMutex`
+
+4. **Ensure it compiles** — run `dotnet build dotnet/`
+
+5. **Mark complete**:
+
+```bash
+dotnet run --project tools/NatsNet.PortTracker -- feature update <id> --status complete --db porting.db
+```
+
+### Implementing a Unit Test
+
+1. **Read the Go test** — use `test show <id>` to get Go source location.
+2. **Read the corresponding .NET feature** to understand the API surface.
+3. **Write the test** in `dotnet/tests/ZB.MOM.NatsNet.Server.Tests/` using xUnit 3 + Shouldly + NSubstitute.
+4. **Run it**:
+
+```bash
+dotnet test --filter "FullyQualifiedName~TestClassName" \
+  dotnet/tests/ZB.MOM.NatsNet.Server.Tests/
+```
+
+5. **Mark verified** (if passing):
+
+```bash
+dotnet run --project tools/NatsNet.PortTracker -- test update <id> --status verified --db porting.db
+```
+
+### After Completing Work
+
+1. Run affected tests to verify nothing broke.
+2. Update DB status for all items you changed.
+3. Check what's newly unblocked:
+
+```bash
+dotnet run --project tools/NatsNet.PortTracker -- dependency ready --db porting.db
+```
+
+4. Generate updated report:
+
+```bash
+./reports/generate-report.sh
+```
+
+## Go to .NET Translation Reference

+# Phase 7: Porting Verification — Design
+
+**Date:** 2026-02-26
+**Scope:** Verify all ported code through targeted testing; mark server-integration tests as `deferred`
+
+---
+
+## Context
+
+After Phase 6 (23 porting sessions + 93 stub completions), the DB state entering Phase 7:
+
+| Item | Count |
+|------|-------|
+| Features complete | 3,596 / 3,673 (77 n_a) |
+| Unit tests complete | 319 |
+| Unit tests stub | 224 |
+| Unit tests not_started | 2,533 |
+| Unit tests n_a | 181 |
+| Unit tests total | 3,257 |
+
+635 unit tests currently pass. 166 `NotImplementedException` stubs remain in the server — the .NET server is not yet runnable end-to-end.
+
+---
+
+## Key Design Decision: Two Test Layers
+
+Go test files (`jetstream_test.go`, `monitor_test.go`, etc.) all use `RunBasicJetStreamServer()` / `RunServer()` — they start a real NATS server over TCP, then connect via NATS client. These are server-integration tests regardless of whether they target a single node or a cluster.
+
+| Layer | Tests | Treatment |
+|-------|-------|-----------|
+| **Unit** | Pure component logic (no server startup) | Port & verify in Phase 7 |
+| **Server-integration** | Require running NatsServer + NATS client | Status `deferred` |
+
+---
+
+## Schema Extension
+
+Add `deferred` to the `unit_tests.status` CHECK constraint:
+
+```sql
+-- Migration: add 'deferred' to unit_tests status enum
+-- Recreate table with updated constraint or use SQLite trigger workaround
+```
+
+`deferred` = test blocked on running server or cluster infrastructure. Distinct from `n_a` (not applicable to this port).
+
+---
+
+## Test Classification
+
+### Unit Tests to Port (~631 new tests)
+
+| Go source file | Not-started / Stub | Component |
+|---|---|---|
+| `opts_test.go` | 77 stubs + remaining | Config parsing / binding |
+| `jwt_test.go` | 88 stubs | JWT decode / validate |
+| `auth_test.go` | 6 stubs | Auth handler logic |
+| `auth_callout_test.go` | 31 stubs | Auth callout types / helpers |
+| `signal_test.go` | 16 stubs | Signal handler registration |
+| `log_test.go` | 3 stubs | Logger behaviour |
+| `config_check_test.go` | 3 stubs | Config validation |
+| `memstore_test.go` | 41 not_started | Memory store logic |
+| `store_test.go` | 17 not_started | Store interface contract |
+| `filestore_test.go` | 249 not_started | File store read/write/purge |
+| `jetstream_errors_test.go` | 4 not_started | Error type checks |
+| `jetstream_versioning_test.go` | 18 not_started | Version compatibility |
+| `jetstream_batching_test.go` | 29 not_started | Batching logic |
+| `dirstore_test.go` | 12 not_started | JWT directory store |
+| `accounts_test.go` | 31 not_started | Account logic (unit subset) |
+| `thw` module | 6 not_started | Time hash wheel |
+
+### Server-Integration Tests → `deferred` (~1,799 tests)
+
+| Go source file | Count | Deferred reason |
+|---|---|---|
+| `jetstream_test.go` | 320 | Needs running server |
+| `jetstream_consumer_test.go` | 161 | Needs running server |
+| `monitor_test.go` | 103 | HTTP monitoring endpoints |
+| `reload_test.go` | 73 | Live config reload |
+| `routes_test.go` | 70 | Multi-server routing |
+| `events_test.go` | 52 | Server event bus |
+| `server_test.go` | 20 | Server lifecycle |
+| `jetstream_cluster_*` (×4) | 456 | Multi-node cluster |
+| `mqtt_test.go` + extras | ~162 | MQTT server |
+| `websocket_test.go` | 109 | WebSocket server |
+| `raft_test.go` | 104 | Raft consensus |
+| `leafnode_test.go` + proxy | 120 | Leaf node infrastructure |
+| `gateway_test.go` | 88 | Gateway infrastructure |
+| `jetstream_super_cluster_test.go` | 47 | Super-cluster |
+| `norace_*` tests | ~141 | Race-detector / timing |
+| Benchmark tests | ~20 | Performance only |
+| Other cluster/misc | ~53 | Cluster infrastructure |
+
+---
+
+## Session Structure (10 sessions)
+
+| Session | Scope | New tests | Source files |
+|---------|-------|-----------|---|
+| **P7-01** | Schema migration + small module verification | 0 new (114 existing) | ats, avl, certidp, gsl, pse, stree, thw, tpm |
+| **P7-02** | Opts & config stubs + remaining opts tests | ~95 | `opts_test.go` |
+| **P7-03** | JWT stubs | 88 | `jwt_test.go` |
+| **P7-04** | Auth stubs + auth callout stubs | 37 | `auth_test.go`, `auth_callout_test.go`, `config_check_test.go` |
+| **P7-05** | Signal + log stubs | 19 | `signal_test.go`, `log_test.go` |
+| **P7-06** | Store unit tests — memory + interface | ~58 | `memstore_test.go`, `store_test.go` |
+| **P7-07** | File store unit tests (first half) | ~125 | `filestore_test.go` lines 1–~4,000 |
+| **P7-08** | File store unit tests (second half) | ~124 | `filestore_test.go` remainder |
+| **P7-09** | JetStream unit tests — errors, versioning, batching, dirstore, accounts | ~94 | `jetstream_errors_test.go`, `jetstream_versioning_test.go`, `jetstream_batching_test.go`, `dirstore_test.go`, `accounts_test.go` |
+| **P7-10** | Mark deferred, integration tests, DB final update, Phase 7 close | — | DB sweep + Gitea milestones 7 & 8 |
+
+**Total new tests written: ~640**
+
+---
+
+## Verification Flow (per session)
+
+1. Write / fill tests → build → run → confirm green
+2. Mark tests `complete` in DB (new tests) then `verified`
+3. Mark small modules `verified` in DB (P7-01); server module at P7-10
+4. `./reports/generate-report.sh` → commit
+
+---
+
+## Integration Tests (P7-10)
+
+Replace the placeholder `UnitTest1.cs` with `NatsServerBehaviorTests.cs`. Tests run against the **Go NATS server** (not the .NET server) to establish a behavioral baseline:
+
+- Basic pub/sub
+- Wildcard matching (`foo.*`, `foo.>`)
+- Queue groups
+- Connect/disconnect lifecycle
+- Protocol error handling
+
+---
+
+## Completion Definition
+
+Phase 7 is complete when:
+- All non-`n_a`, non-`deferred` tests are `verified`
+- `dotnet run --project tools/NatsNet.PortTracker -- phase check 7 --db porting.db` passes
+- Gitea issues #45–#52 closed
+- Gitea milestones 7 and 8 closed
+
+The ~1,799 `deferred` tests remain for a future phase once the .NET server is end-to-end runnable.

+# AGENTS.md Design
+
+## Purpose
+
+Create an `AGENTS.md` file at the project root for OpenAI Codex agents working on this codebase. The file provides project context, PortTracker CLI reference, porting workflow guidance, and pointers to .NET coding standards.
+
+## Target
+
+OpenAI Codex — follows Codex's AGENTS.md discovery conventions (root-level, markdown format, under 32KB).
+
+## Structure Decision
+
+**Flat single-file** at project root. The project information is tightly coupled — PortTracker commands are needed regardless of which directory Codex is editing. A single file keeps everything in context for every session.
+
+## Sections
+
+1. **Project Summary** — What the project is, where Go source and .NET code live
+2. **Folder Layout** — Directory tree with annotations
+3. **Build and Test** — Commands to build, run unit tests, run filtered tests, run integration tests
+4. **.NET Coding Standards** — Pointer to `docs/standards/dotnet-standards.md` with critical rules inlined (forbidden packages, naming, testing framework)
+5. **PortTracker CLI** — Full command reference: querying, updating, audit verification, valid statuses, batch syntax
+6. **Porting Workflow** — Step-by-step: finding work, implementing features, implementing tests, post-completion checklist
+7. **Go to .NET Translation Reference** — Quick-reference table for common Go-to-.NET pattern translations
+
+## Size
+
+~3.5KB — well within Codex's 32KB default limit.

+# Audit-Verified Status Updates Design
+
+## Goal
+
+Require audit verification before applying status changes to features or unit tests. When the requested status disagrees with what the Roslyn audit determines, require an explicit override with a comment. Track all overrides in a new table for later review.
+
+## Architecture
+
+Inline audit verification: when `feature update`, `feature batch-update`, `test update`, or `test batch-update` runs, build the `SourceIndexer` on the fly, classify each item, and compare. If the requested status doesn't match the audit, block the update unless `--override "comment"` is provided.
+
+## Override Table Schema
+
+```sql
+CREATE TABLE status_overrides (
+    id INTEGER PRIMARY KEY AUTOINCREMENT,
+    table_name TEXT NOT NULL CHECK (table_name IN ('features', 'unit_tests')),
+    item_id INTEGER NOT NULL,
+    audit_status TEXT NOT NULL,
+    audit_reason TEXT NOT NULL,
+    requested_status TEXT NOT NULL,
+    comment TEXT NOT NULL,
+    created_at DATETIME DEFAULT CURRENT_TIMESTAMP
+);
+```
+
+Each row records: which table/item, what the audit said, what the user requested, and their justification.
+
+## CLI Interface
+
+### Single update
+
+```bash
+# Audit agrees — applied directly
+dotnet run -- feature update 123 --status verified --db porting.db
+
+# Audit disagrees — blocked
+# Error: "Audit classifies feature 123 as 'stub'. Use --override 'reason' to force."
+
+# Override
+dotnet run -- feature update 123 --status verified --override "Manual review confirms complete" --db porting.db
+```
+
+### Batch update
+
+```bash
+# All items agree — applied
+dotnet run -- feature batch-update --module 5 --set-status verified --execute --db porting.db
+
+# Some items disagree — blocked
+# "15 items match audit, 3 require override. Use --override 'reason' to force all."
+
+# Override entire batch (one comment covers all mismatches)
+dotnet run -- feature batch-update --module 5 --set-status verified --override "Batch approved" --execute --db porting.db
+```
+
+Same interface for `test update` and `test batch-update`.
+
+## Verification Flow
+
+1. Build `SourceIndexer` for the appropriate directory (features → `dotnet/src/...`, tests → `dotnet/tests/...`).
+2. For each item: query its `dotnet_class`, `dotnet_method`, `go_file`, `go_method` from DB. Run `FeatureClassifier.Classify()`.
+3. Compare requested status vs audit status. Collect mismatches.
+4. If mismatches and no `--override`: print details and exit with error.
+5. If `--override` provided: apply all updates. Insert one `status_overrides` row per mismatched item.
+6. Items that agree with audit: apply normally, no override row logged.
+
+Items that cannot be audited (no dotnet_class/dotnet_method) are treated as mismatches requiring override.
+
+## Override Review Command
+
+```bash
+dotnet run -- override list --db porting.db
+dotnet run -- override list --type features --db porting.db
+```
+
+Tabular output: id, table, item_id, audit_status, requested_status, comment, date.
+
+## Changes Required
+
+1. **porting-schema.sql**: Add `status_overrides` table.
+2. **FeatureCommands.cs**: Add `--override` option to `update` and `batch-update`. Integrate audit verification before applying.
+3. **TestCommands.cs**: Same changes as FeatureCommands.
+4. **New `OverrideCommands.cs`**: `override list` command.
+5. **Program.cs**: Wire `override` command group.
+6. **Shared helper**: Extract audit verification logic (build indexer, classify, compare) into a reusable method since both feature and test commands need it.

+# Feature Audit Script Design
+
+**Date:** 2026-02-27
+**Status:** Approved
+
+## Problem
+
+3394 features in module 8 (`server`) are marked `unknown`. The existing plan (`2026-02-27-feature-status-audit-plan.md`) describes a manual 68-batch process of inspecting .NET source and classifying each feature. This design automates that process.
+
+## Solution
+
+A new PortTracker CLI command `feature audit` that uses Roslyn syntax tree analysis to parse .NET source files, build a method index, and classify all unknown features automatically.
+
+## Command Interface
+
+```
+dotnet run --project tools/NatsNet.PortTracker -- feature audit \
+  --source dotnet/src/ZB.MOM.NatsNet.Server/ \
+  --output reports/audit-results.csv \
+  --db porting.db \
+  [--module 8] \
+  [--execute]
+```
+
+| Flag | Default | Description |
+|------|---------|-------------|
+| `--source` | `dotnet/src/ZB.MOM.NatsNet.Server/` | .NET source directory to parse |
+| `--output` | `reports/audit-results.csv` | CSV report output path |
+| `--db` | `porting.db` | SQLite database (inherited from root) |
+| `--module` | *(all)* | Restrict to a specific module ID |
+| `--execute` | `false` | Apply DB updates (default: dry-run) |
+
+## Architecture
+
+### Component 1: Source Indexer (`Audit/SourceIndexer.cs`)
+
+Parses all `.cs` files under the source directory into Roslyn syntax trees and builds a lookup index.
+
+**Process:**
+1. Recursively glob `**/*.cs` (skip `obj/`, `bin/`)
+2. Parse each file with `CSharpSyntaxTree.ParseText()`
+3. Walk syntax trees for `ClassDeclarationSyntax` and `StructDeclarationSyntax`
+4. Extract all method, property, and constructor declarations
+5. Build dictionary: `Dictionary<(string className, string memberName), List<MethodInfo>>`
+
+**`MethodInfo`:**
+- `FilePath` — source file path
+- `LineNumber` — starting line
+- `BodyLineCount` — lines in method body (excluding braces)
+- `IsStub` — body is `throw new NotImplementedException(...)` or empty
+- `IsPartial` — body has some logic AND a `NotImplementedException` throw
+- `StatementCount` — number of meaningful statements
+
+**Partial class handling:** Same class name across multiple files produces multiple entries in the index. Lookup checks all of them — a feature is matched if the method exists in ANY file for that class.
+
+**Name matching:** Case-insensitive comparison for both class and method names. Handles `dotnet_class` values that contain commas (e.g. `ClosedRingBuffer,ClosedClient`) by splitting and checking each.
+
+### Component 2: Feature Classifier (`Audit/FeatureClassifier.cs`)
+
+Classifies each feature using the source index. Priority order (first match wins):
+
+**1. N/A Lookup Table**
+
+Checked first against `(go_file, go_method)` or `dotnet_class` patterns:
+
+| Pattern | Reason |
+|---------|--------|
+| Go logging functions (`Noticef`, `Debugf`, `Tracef`, `Warnf`, `Errorf`, `Fatalf`) | .NET uses Microsoft.Extensions.Logging |
+| Go signal handling (`HandleSignals`, `processSignal`) | .NET uses IHostApplicationLifetime |
+| Go HTTP handler setup (`Statz`, `Varz`, `Connz`, etc.) | .NET uses ASP.NET middleware |
+
+Table is extensible — add entries as new patterns are identified.
+
+**2. Method Not Found** -> `deferred`
+- `dotnet_class` not found in source index, OR
+- `dotnet_method` not found within the class
+
+**3. Stub Detection** -> `stub`
+- Body is solely `throw new NotImplementedException(...)` (expression-bodied or block)
+- Body is empty (no statements)
+- Body has logic but also contains `NotImplementedException` (partial implementation)
+
+**4. Verified** -> `verified`
+- Method exists with 1+ meaningful statements that are not `NotImplementedException` throws
+
+### Component 3: Audit Command (`Commands/AuditCommand.cs`)
+
+Orchestrates the audit:
+
+1. Query `SELECT id, dotnet_class, dotnet_method, go_file, go_method FROM features WHERE status = 'unknown'` (optionally filtered by module)
+2. Build source index via `SourceIndexer`
+3. Classify each feature via `FeatureClassifier`
+4. Write CSV report
+5. Print console summary
+6. If `--execute`: update DB in a single transaction per status group
+
+### DB Update Strategy
+
+- Group features by `(new_status, notes)` tuple
+- One `UPDATE features SET status = @s, notes = @n WHERE id IN (...)` per group
+- All groups in a single transaction
+- For `n_a` features: set `notes` to the reason from the lookup table
+
+## Output
+
+### CSV Report
+
+```csv
+id,dotnet_class,dotnet_method,go_file,go_method,old_status,new_status,reason
+150,ServiceRespType,String,server/accounts.go,String,unknown,verified,Method found with 3 statements
+151,Account,NewAccount,server/accounts.go,NewAccount,unknown,stub,Body is throw NotImplementedException
+```

+## Files to Create/Modify
+
+| File | Action |
+|------|--------|
+| `tools/NatsNet.PortTracker/NatsNet.PortTracker.csproj` | Add Roslyn package reference |
+| `tools/NatsNet.PortTracker/Audit/SourceIndexer.cs` | New — Roslyn source parsing and indexing |

+
+## Non-Goals
+
+- No semantic analysis (full compilation) — syntax trees are sufficient
+- No Go source parsing — we only inspect .NET source
+- No unit test reclassification — separate effort
+- No code changes to the server project — classification only

+# Feature Audit Script Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers-extended-cc:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add a `feature audit` command to the PortTracker CLI that uses Roslyn syntax tree analysis to automatically classify 3394 unknown features into verified/stub/n_a/deferred.
+
+**Architecture:** Three new files — `SourceIndexer` parses all .cs files and builds a method lookup index, `FeatureClassifier` applies classification heuristics, `AuditCommand` wires the CLI and orchestrates the audit. Direct DB updates via the existing `Database` class.
+
+**Tech Stack:** `Microsoft.CodeAnalysis.CSharp` (Roslyn) for C# parsing, `Microsoft.Data.Sqlite` (existing), `System.CommandLine` (existing)
+
+**Design doc:** `docs/plans/2026-02-27-feature-audit-script-design.md`
+
+---
+
+## Important Rules (Read Before Every Task)
+
+1. All new files go under `tools/NatsNet.PortTracker/`
+2. Follow the existing code style — see `FeatureCommands.cs` and `BatchFilters.cs` for patterns
+3. Use `System.CommandLine` v3 (preview) APIs — `SetAction`, `parseResult.GetValue()`, etc.
+4. The `Database` class methods: `Query()`, `Execute()`, `ExecuteScalar<T>()`, `ExecuteInTransaction()`
+5. Run `dotnet build --project tools/NatsNet.PortTracker` after each file creation to verify compilation
+
+---
+
+### Task 0: Add Roslyn NuGet package
+
+**Files:**
+- Modify: `tools/NatsNet.PortTracker/NatsNet.PortTracker.csproj`
+
+**Step 1: Add the package reference**
+
+Add `Microsoft.CodeAnalysis.CSharp` to the csproj:
+
+```xml
+<PackageReference Include="Microsoft.CodeAnalysis.CSharp" Version="4.13.0" />
+```
+
+The `<ItemGroup>` should look like:
+
+```xml
+<ItemGroup>
+  <PackageReference Include="Microsoft.CodeAnalysis.CSharp" Version="4.13.0" />
+  <PackageReference Include="Microsoft.Data.Sqlite" Version="10.0.3" />
+  <PackageReference Include="System.CommandLine" Version="3.0.0-preview.1.26104.118" />
+</ItemGroup>
+```
+
+**Step 2: Restore and build**
+
+Run: `dotnet build --project tools/NatsNet.PortTracker`
+Expected: Build succeeded. 0 Error(s).
+
+**Step 3: Commit**
+
+```bash
+git add tools/NatsNet.PortTracker/NatsNet.PortTracker.csproj
+git commit -m "chore: add Roslyn package to PortTracker for feature audit"
+```

+    }
+}
+```
+
+**Step 2: Wire the command into Program.cs**
+
+In `tools/NatsNet.PortTracker/Program.cs`, add after the existing command registrations (after line 41, before `var parseResult`):
+
+Find this line:
+```csharp
+rootCommand.Add(PhaseCommands.Create(dbOption, schemaOption));
+```
+
+Add immediately after it:
+```csharp
+rootCommand.Add(AuditCommand.Create(dbOption));
+```
+
+Also add the import — but since the file uses top-level statements and already imports `NatsNet.PortTracker.Commands`, no new using is needed (AuditCommand is in the same namespace).
+
+**Step 3: Build to verify compilation**
+
+Run: `dotnet build --project tools/NatsNet.PortTracker`
+Expected: Build succeeded. 0 Error(s).
+
+**Step 4: Commit**
+
+```bash
+git add tools/NatsNet.PortTracker/Commands/AuditCommand.cs tools/NatsNet.PortTracker/Program.cs
+git commit -m "feat: add audit command — orchestrates feature status classification"
+```
+
+---
+
+### Task 4: Smoke test — dry-run on the real database
+
+**Files:** None — testing only.
+
+**Step 1: Run the audit in dry-run mode**
+
+```bash
+dotnet run --project tools/NatsNet.PortTracker -- audit --source dotnet/src/ZB.MOM.NatsNet.Server/ --db porting.db --output reports/audit-results.csv
+```
+
+Expected output similar to:
+```
+Parsing .NET source files in dotnet/src/ZB.MOM.NatsNet.Server/...
+Indexed ~92 files, ~NNNN methods/properties.
+Found 3394 unknown features to classify.
+
+Feature Status Audit Results
+=============================
+Source: dotnet/src/ZB.MOM.NatsNet.Server/ (92 files, NNNN methods indexed)
+Features audited: 3394
+
+  verified:  NNNN
+  stub:      NNNN
+  n_a:       NNNN
+  deferred:  NNNN
+
+Dry-run mode. Add --execute to apply changes.
+Report: reports/audit-results.csv
+```
+
+**Step 2: Inspect the CSV report**
+
+```bash
+head -20 reports/audit-results.csv
+```
+
+Verify:
+- Header row matches: `id,dotnet_class,dotnet_method,go_file,go_method,old_status,new_status,reason`
+- Each row has a classification and reason
+- The known n_a features (Noticef, Debugf etc.) show as `n_a`
+
+**Step 3: Spot-check a few classifications**
+
+Pick 3-5 features from the CSV and manually verify:
+- A `verified` feature: check the .NET method has real logic
+- A `stub` feature: check the .NET method is `throw new NotImplementedException`
+- A `deferred` feature: check the class/method doesn't exist
+- An `n_a` feature: check it's a Go logging function
+
+If any classifications are wrong, fix the heuristics before proceeding.
+
+**Step 4: Check the counts add up**
+
+```bash
+wc -l reports/audit-results.csv
+```
+
+Expected: 3395 lines (3394 data rows + 1 header).
+
+---
+
+### Task 5: Execute the audit and update the database
+
+**Files:** None — execution only.
+
+**Step 1: Back up the database**
+
+```bash
+cp porting.db porting.db.pre-audit-backup
+```
+
+**Step 2: Run with --execute**
+
+```bash
+dotnet run --project tools/NatsNet.PortTracker -- audit --source dotnet/src/ZB.MOM.NatsNet.Server/ --db porting.db --output reports/audit-results.csv --execute
+```
+
+Expected: `Updated 3394 features.`
+
+**Step 3: Verify zero unknown features remain**
+
+```bash
+dotnet run --project tools/NatsNet.PortTracker -- feature list --status unknown --db porting.db
+```
+
+Expected: `Total: 0 features`
+
+**Step 4: Verify status breakdown**
+
+```bash
+dotnet run --project tools/NatsNet.PortTracker -- report summary --db porting.db
+```
+
+Review the numbers match the dry-run output.
+
+**Step 5: Generate updated porting report**
+
+```bash
+./reports/generate-report.sh
+```
+
+**Step 6: Commit everything**
+
+```bash
+git add porting.db reports/ tools/NatsNet.PortTracker/
+git commit -m "feat: run feature status audit — classify 3394 unknown features
+
+Automated classification using Roslyn syntax tree analysis:
+  verified:  NNNN (update with actual numbers)
+  stub:      NNNN
+  n_a:       NNNN
+  deferred:  NNNN"
+```
+
+(Update the commit message with the actual numbers from the output.)
+
+---
+
+### Task 6: Cleanup — remove backup
+
+**Files:** None.
+
+**Step 1: Verify everything is committed and the database is correct**
+
+```bash
+git status
+dotnet run --project tools/NatsNet.PortTracker -- feature list --status unknown --db porting.db
+```
+
+Expected: clean working tree, 0 unknown features.
+
+**Step 2: Remove the pre-audit backup**
+
+```bash
+rm porting.db.pre-audit-backup
+```
+
+**Step 3: Final summary**
+
+Print:
+```
+Feature Status Audit Complete

+# Feature Status Audit Design
+
+**Date:** 2026-02-27
+**Status:** Approved
+
+## Problem
+
+3394 features in module 8 (`server`) are marked as `unknown` status after a bulk reclassification. Each needs to be checked against its .NET implementation to determine the correct status.
+
+## Scope
+
+- **Module:** 8 (server) — all 3394 unknown features
+- **Go source files:** 64 distinct files
+- **All features have `dotnet_class` and `dotnet_method` mappings** — no unmapped features
+
+## Classification Criteria
+
+| Status | Criteria | Example |
+|--------|----------|---------|
+| `verified` | .NET method exists with non-trivial logic matching Go behavior | `MemStore.StoreRawMsg` — full implementation |
+| `stub` | .NET method exists but is `throw new NotImplementedException()`, empty, or only partially implemented | `FileStore.Compact` — no real logic |
+| `n_a` | Go feature doesn't apply to .NET — .NET uses a different approach (different library, runtime feature, or platform pattern) | Go logging functions → .NET uses `Microsoft.Extensions.Logging` |
+| `deferred` | .NET method doesn't exist, or classification requires running the server end-to-end | Server-integration features needing full runtime |
+
+**Partial implementations** (method exists with some logic but missing significant functionality) are classified as `stub`.
+
+## Batch Execution Process
+
+Features are processed in fixed batches of 50. Each batch follows this workflow:
+
+### Step 1: Fetch next 50 unknown features
+
+```bash
+dotnet run --project tools/NatsNet.PortTracker -- feature list --module 8 --status unknown --db porting.db
+```
+
+Take the first 50 IDs from the output.
+
+### Step 2: Inspect .NET source for each feature
+
+For each feature:
+1. Read the `dotnet_class` and `dotnet_method` from the feature record
+2. Find the .NET source file containing that class
+3. Check the method body:
+   - Real logic matching Go = `verified`
+   - Stub / empty / partial = `stub`
+   - .NET alternative exists = `n_a`
+   - Method not found = `deferred`
+
+### Step 3: Dry-run the batch update (MANDATORY)
+
+Group features by their determined status and dry-run using PortTracker:
+
+```bash
+# Dry-run — verify correct features affected
+dotnet run --project tools/NatsNet.PortTracker -- feature batch-update --ids 150-160 --set-status deferred --db porting.db
+dotnet run --project tools/NatsNet.PortTracker -- feature batch-update --ids 2068-2077 --set-status verified --db porting.db
+```
+
+Review the preview output. Only proceed if the listed features match expectations.
+
+### Step 4: Execute once dry-run verified
+
+```bash
+dotnet run --project tools/NatsNet.PortTracker -- feature batch-update --ids 150-160 --set-status deferred --execute --db porting.db
+dotnet run --project tools/NatsNet.PortTracker -- feature batch-update --ids 2068-2077 --set-status verified --execute --db porting.db
+```
+
+### Step 5: Verify remaining count
+
+```bash
+dotnet run --project tools/NatsNet.PortTracker -- feature list --status unknown --db porting.db
+```
+
+Confirm the count decreased by ~50.
+
+## Rules
+
+1. **ALWAYS dry-run before executing** — no exceptions
+2. **NEVER use direct SQL** (`sqlite3`) — use PortTracker CLI exclusively
+3. **Process exactly 50 per batch** (or fewer if fewer remain)
+4. **Report classification breakdown** after each batch (e.g. "Batch 3: 12 verified, 30 stub, 3 n_a, 5 deferred")
+5. **68 batches total** (3394 / 50 = ~68)
+
+## Key .NET Source Locations
+
+```

+  Accounts/Account.cs, AccountResolver.cs, DirJwtStore.cs
+  Auth/AuthHandler.cs, JwtProcessor.cs

+  Mqtt/MqttHandler.cs, WebSocket/WebSocketTypes.cs
+  Internal/ (various data structures)
+  NatsServer.cs, NatsServer.*.cs (partial class files)
+  ClientConnection.cs
+```
+
+## Non-Goals
+
+- No code changes — this is classification only
+- No unit_tests reclassification (separate effort)
+- No schema changes needed (`unknown` already added)

+# Feature Status Audit Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers-extended-cc:executing-plans to implement this plan task-by-task.
+
+**Goal:** Classify 3394 features currently marked `unknown` into the correct status (`verified`, `stub`, `n_a`, or `deferred`) by inspecting .NET source code against Go feature specifications.
+
+**Architecture:** Process features in sequential batches of 50. Each batch: fetch 50 unknown features via PortTracker CLI, inspect the corresponding .NET source files, classify each feature, dry-run the batch updates, then execute. Repeat until zero unknown features remain.
+
+**Tech Stack:** PortTracker CLI (`dotnet run --project tools/NatsNet.PortTracker`), .NET source at `dotnet/src/ZB.MOM.NatsNet.Server/`
+
+**Design doc:** `docs/plans/2026-02-27-feature-status-audit-design.md`
+
+---
+
+## Important Rules (Read Before Every Task)
+
+1. **ALWAYS dry-run before executing** — no exceptions. Every `batch-update` command must be run WITHOUT `--execute` first to preview.
+2. **NEVER use direct SQL** (`sqlite3`) — use the PortTracker CLI exclusively for all database operations.
+3. **Process exactly 50 per batch** (or fewer if fewer remain in the final batch).
+4. **Report classification breakdown** after each batch (e.g. "Batch 3: 12 verified, 30 stub, 3 n_a, 5 deferred").
+
+## Classification Criteria Reference
+
+| Status | Criteria |
+|--------|----------|
+| `verified` | .NET method exists with non-trivial logic that matches the Go implementation's behavior |
+| `stub` | .NET method exists but is `throw new NotImplementedException()`, empty, or only **partially** implemented (has structure but missing significant logic) |
+| `n_a` | Go feature doesn't apply to .NET — .NET uses a different approach (e.g. Go logging → .NET uses `Microsoft.Extensions.Logging`) |
+| `deferred` | .NET method doesn't exist at all, or classification requires the server running end-to-end |

+### Task 0: Verify starting state and PortTracker commands
+
+**Files:** None — verification only.
+
+**Step 1: Check how many unknown features exist**
+
+```bash
+dotnet run --project tools/NatsNet.PortTracker -- feature list --module 8 --status unknown --db porting.db
+```
+
+Expected: Output shows ~3394 features. Note the total count at the bottom.
+
+**Step 2: Verify batch-update dry-run works**
+
+```bash
+dotnet run --project tools/NatsNet.PortTracker -- feature batch-update --ids 150-152 --set-status verified --db porting.db
+```
+
+Expected: Preview output showing 3 features. Should say "Would affect 3 items:" and "Add --execute to apply these changes." Do NOT execute — this is just confirming the tool works.
+
+**Step 3: Record the starting count**
+
+Note the total unknown count. This is your baseline. After all batches complete, the count should be 0.
+
+---
+
+### Task N (repeat for N=1 through 68): Process batch of 50 unknown features
+
+> **This task is a template.** Repeat it until zero unknown features remain. Each execution processes the next 50.
+
+**Files:** None — classification only, no code changes.
+
+**Step 1: Fetch the next 50 unknown features**
+
+```bash
+dotnet run --project tools/NatsNet.PortTracker -- feature list --module 8 --status unknown --db porting.db
+```
+
+From the output, take the **first 50 feature IDs**. Note the `dotnet_class` and `dotnet_method` columns for each.
+
+**Step 2: For each feature, inspect the .NET implementation**
+
+For each of the 50 features:
+
+1. **Find the .NET source file** — use `Grep` to search for the class:
+   ```
+   Grep pattern: "class {dotnet_class}" path: dotnet/src/ZB.MOM.NatsNet.Server/
+   ```
+
+2. **Find the method** — search within that file for the method name:
+   ```
+   Grep pattern: "{dotnet_method}" path: {the file found above}
+   ```
+
+3. **Read the method body** — use `Read` to view the method implementation.
+
+4. **Classify the feature:**
+   - If the method has real, non-trivial logic matching the Go behavior → `verified`
+   - If the method is `throw new NotImplementedException()`, empty, or only partially there → `stub`
+   - If the Go feature has a .NET-native replacement (e.g., Go's custom logging → `Microsoft.Extensions.Logging`, Go's `sync.Mutex` → C#'s `Lock`) → `n_a`
+   - If the method doesn't exist in the .NET codebase at all → `deferred`
+
+**Efficiency tip:** Features from the same `dotnet_class` should be inspected together — read the .NET file once and classify all features from that class in the batch.
+
+**Step 3: Group IDs by classification result**
+
+After inspecting all 50, organize the IDs into groups:
+
+```
+verified_ids: 2068,2069,2070,2071,...
+stub_ids: 2080,2081,...
+n_a_ids: 2090,...
+deferred_ids: 2095,2096,...
+```
+
+**Step 4: Dry-run each group (MANDATORY — DO NOT SKIP)**
+
+Run the dry-run for EACH status group. Review the output carefully.
+
+```bash
+# Dry-run verified
+dotnet run --project tools/NatsNet.PortTracker -- feature batch-update --ids {verified_ids} --set-status verified --db porting.db
+
+# Dry-run stub
+dotnet run --project tools/NatsNet.PortTracker -- feature batch-update --ids {stub_ids} --set-status stub --db porting.db
+
+# Dry-run n_a (include reason in notes)
+dotnet run --project tools/NatsNet.PortTracker -- feature batch-update --ids {n_a_ids} --set-status n_a --set-notes "{reason}" --db porting.db
+
+# Dry-run deferred
+dotnet run --project tools/NatsNet.PortTracker -- feature batch-update --ids {deferred_ids} --set-status deferred --db porting.db
+```
+
+Check that:
+- The feature names in the preview match what you inspected
+- The count per group adds up to 50 (or the batch size)
+- No unexpected features appear
+
+**Step 5: Execute each group**
+
+Only after verifying ALL dry-runs look correct:
+
+```bash
+# Execute verified
+dotnet run --project tools/NatsNet.PortTracker -- feature batch-update --ids {verified_ids} --set-status verified --execute --db porting.db
+
+# Execute stub
+dotnet run --project tools/NatsNet.PortTracker -- feature batch-update --ids {stub_ids} --set-status stub --execute --db porting.db
+
+# Execute n_a (with notes)
+dotnet run --project tools/NatsNet.PortTracker -- feature batch-update --ids {n_a_ids} --set-status n_a --set-notes "{reason}" --execute --db porting.db
+
+# Execute deferred
+dotnet run --project tools/NatsNet.PortTracker -- feature batch-update --ids {deferred_ids} --set-status deferred --execute --db porting.db
+```
+
+**Step 6: Verify remaining count decreased**
+
+```bash
+dotnet run --project tools/NatsNet.PortTracker -- feature list --status unknown --db porting.db
+```
+
+Confirm the total decreased by ~50 from the previous batch.
+
+**Step 7: Report batch summary**
+
+Print: `Batch N: X verified, Y stub, Z n_a, W deferred (Total remaining: NNNN)`
+
+---
+
+### Task 69: Final verification and report
+
+**Files:** None — verification only.
+
+**Step 1: Confirm zero unknown features remain**
+
+```bash
+dotnet run --project tools/NatsNet.PortTracker -- feature list --status unknown --db porting.db
+```
+
+Expected: `Total: 0 features`
+
+**Step 2: Generate the full status breakdown**
+
+```bash
+dotnet run --project tools/NatsNet.PortTracker -- feature list --module 8 --status verified --db porting.db
+dotnet run --project tools/NatsNet.PortTracker -- feature list --module 8 --status stub --db porting.db
+dotnet run --project tools/NatsNet.PortTracker -- feature list --module 8 --status n_a --db porting.db
+dotnet run --project tools/NatsNet.PortTracker -- feature list --module 8 --status deferred --db porting.db
+```
+
+Note the count for each status.
+
+**Step 3: Generate updated porting report**
+
+```bash
+./reports/generate-report.sh
+```
+
+**Step 4: Commit the updated report**
+
+```bash
+git add reports/
+git commit -m "chore: update porting report after feature status audit"
+```
+
+**Step 5: Print final summary**
+
+```
+Feature Status Audit Complete
+=============================
+Total features audited: 3394
+  verified:  NNNN
+  stub:      NNNN
+  n_a:       NNNN
+  deferred:  NNNN

+# PortTracker Batch Operations Design
+
+**Date:** 2026-02-27
+**Status:** Approved
+
+## Problem
+
+The PortTracker CLI only supports one-at-a-time operations for status updates, mappings, and N/A marking. With ~3700 features and ~3300 tests, bulk operations require dropping to raw `sqlite3` commands. This is error-prone and bypasses any validation the CLI could provide.
+
+## Design
+
+### Approach
+
+Add `batch-update` and `batch-map` subcommands under each existing entity command (`feature`, `test`, `module`, `library`). All batch commands share a common filter + dry-run infrastructure.
+
+### Shared Batch Infrastructure
+
+A new `BatchFilters` static class in `Commands/BatchFilters.cs` provides:
+
+**Filter Options** (combined with AND logic):
+- `--ids <range>` — ID range like `100-200`, comma-separated `1,5,10`, or mixed `1-5,10,20-25`
+- `--module <id>` — filter by module_id (feature/test only)
+- `--status <status>` — filter by current status value
+
+**Dry-Run Default:**
+- Without `--execute`, commands show a preview: "Would affect N items:" + table of matching rows
+- With `--execute`, changes are applied inside a transaction and "Updated N items." is printed
+- At least one filter is required (no accidental "update everything" with zero filters)
+
+**Shared Methods:**
+- `AddFilterOptions(Command cmd, bool includeModuleFilter)` — adds the common options to a command
+- `BuildWhereClause(...)` — returns SQL WHERE clause + parameters from parsed filter values
+- `PreviewOrExecute(Database db, string table, string selectSql, string updateSql, params[], bool execute)` — handles dry-run preview vs actual execution
+
+### Feature Batch Commands
+
+**`feature batch-update`**
+- Filters: `--ids`, `--module`, `--status`
+- Setters: `--set-status` (required), `--set-notes` (optional)
+- Flag: `--execute`
+
+**`feature batch-map`**
+- Filters: `--ids`, `--module`, `--status`
+- Setters: `--set-project`, `--set-class`, `--set-method` (at least one required)
+- Flag: `--execute`
+
+### Test Batch Commands
+
+**`test batch-update`**
+- Filters: `--ids`, `--module`, `--status`
+- Setters: `--set-status` (required), `--set-notes` (optional)
+- Flag: `--execute`
+
+**`test batch-map`**
+- Filters: `--ids`, `--module`, `--status`
+- Setters: `--set-project`, `--set-class`, `--set-method` (at least one required)
+- Flag: `--execute`
+
+### Module Batch Commands
+
+**`module batch-update`**
+- Filters: `--ids`, `--status`
+- Setters: `--set-status` (required), `--set-notes` (optional)
+- Flag: `--execute`
+
+**`module batch-map`**
+- Filters: `--ids`, `--status`
+- Setters: `--set-project`, `--set-namespace`, `--set-class` (at least one required)
+- Flag: `--execute`
+
+### Library Batch Commands
+
+**`library batch-update`**
+- Filters: `--ids`, `--status`
+- Setters: `--set-status` (required), `--set-notes` (optional, maps to `dotnet_usage_notes`)
+- Flag: `--execute`
+
+**`library batch-map`**
+- Filters: `--ids`, `--status`
+- Setters: `--set-package`, `--set-namespace`, `--set-notes` (at least one required)
+- Flag: `--execute`
+
+## Examples
+
+```bash
+# Preview: which features in module 5 are not_started?
+porttracker feature batch-update --module 5 --status not_started --set-status deferred
+
+# Execute: defer all features in module 5 with a reason
+porttracker feature batch-update --module 5 --status not_started --set-status deferred --set-notes "needs server runtime" --execute
+
+# Execute: mark tests 500-750 as deferred
+porttracker test batch-update --ids 500-750 --set-status deferred --set-notes "server-integration" --execute
+
+# Execute: batch-map all features in module 3 to a .NET project
+porttracker feature batch-map --module 3 --set-project "ZB.MOM.NatsNet.Server" --execute
+
+# Preview: what libraries are unmapped?
+porttracker library batch-update --status not_mapped --set-status mapped
+
+# Execute: batch-map libraries
+porttracker library batch-map --ids 1-20 --set-package "Microsoft.Extensions.Logging" --set-namespace "Microsoft.Extensions.Logging" --execute
+```
+
+## File Changes
+
+| File | Change |
+|------|--------|
+| `Commands/BatchFilters.cs` | New — shared filter options, WHERE builder, preview/execute logic |
+| `Commands/FeatureCommands.cs` | Add `batch-update` and `batch-map` subcommands |
+| `Commands/TestCommands.cs` | Add `batch-update` and `batch-map` subcommands |
+| `Commands/ModuleCommands.cs` | Add `batch-update` and `batch-map` subcommands |
+| `Commands/LibraryCommands.cs` | Add `batch-update` and `batch-map` subcommands |
+| `Data/Database.cs` | Add `ExecuteInTransaction` helper for batch safety |
+
+## Non-Goals
+
+- No batch create or batch delete — not needed for the porting workflow
+- No raw `--where` SQL escape hatch — structured filters cover all use cases
+- No interactive y/n prompts — dry-run + `--execute` flag is sufficient and scriptable

+# PortTracker Batch Operations Implementation Plan
+
+> **For Claude:** REQUIRED SUB-SKILL: Use superpowers-extended-cc:executing-plans to implement this plan task-by-task.
+
+**Goal:** Add batch-update and batch-map subcommands to all PortTracker entity commands (feature, test, module, library) with shared filter infrastructure and dry-run-by-default safety.
+
+**Architecture:** A shared `BatchFilters` static class provides reusable filter options (`--ids`, `--module`, `--status`), WHERE clause building, and the dry-run/execute pattern. Each entity command file gets two new subcommands that delegate filtering and execution to `BatchFilters`. The `Database` class gets an `ExecuteInTransaction` helper.
+
+**Tech Stack:** .NET 10, System.CommandLine v3 preview, Microsoft.Data.Sqlite
+
+**Design doc:** `docs/plans/2026-02-27-porttracker-batch-design.md`

+
+### Task 0: Add ExecuteInTransaction to Database
+
+**Files:**
+- Modify: `tools/NatsNet.PortTracker/Data/Database.cs:73` (before Dispose)
+
+**Step 1: Add the method**
+
+Add this method to `Database.cs` before the `Dispose()` method (line 73):
+
+```csharp
+public int ExecuteInTransaction(string sql, params (string name, object? value)[] parameters)
+{
+    using var transaction = _connection.BeginTransaction();
+    try
+    {
+        using var cmd = CreateCommand(sql);
+        cmd.Transaction = transaction;
+        foreach (var (name, value) in parameters)
+            cmd.Parameters.AddWithValue(name, value ?? DBNull.Value);
+        var affected = cmd.ExecuteNonQuery();
+        transaction.Commit();
+        return affected;
+    }
+    catch
+    {
+        transaction.Rollback();
+        throw;
+    }
+}
+```
+
+**Step 2: Verify it compiles**
+
+Run: `dotnet build tools/NatsNet.PortTracker/NatsNet.PortTracker.csproj`
+Expected: Build succeeded.
+
+**Step 3: Commit**
+
+```bash
+git add tools/NatsNet.PortTracker/Data/Database.cs
+git commit -m "feat(porttracker): add ExecuteInTransaction to Database"
+```
+
+---
+
+### Task 1: Create BatchFilters shared infrastructure
+
+**Files:**
+- Create: `tools/NatsNet.PortTracker/Commands/BatchFilters.cs`
+
+**Step 1: Create the file**

+### Task 2: Add batch commands to FeatureCommands
+
+**Files:**
+- Modify: `tools/NatsNet.PortTracker/Commands/FeatureCommands.cs:169-175`
+
+**Step 1: Add batch-update and batch-map subcommands**
+
+In `FeatureCommands.cs`, insert the batch commands before the `return featureCommand;` line (line 175). Add them after the existing `featureCommand.Add(naCmd);` at line 173.
+
+Replace lines 169-175 with:
+
+```csharp
+        featureCommand.Add(listCmd);
+        featureCommand.Add(showCmd);
+        featureCommand.Add(updateCmd);
+        featureCommand.Add(mapCmd);
+        featureCommand.Add(naCmd);
+        featureCommand.Add(CreateBatchUpdate(dbOption));
+        featureCommand.Add(CreateBatchMap(dbOption));
+
+        return featureCommand;
+```

+### Task 5: Add batch commands to LibraryCommands
+
+**Files:**
+- Modify: `tools/NatsNet.PortTracker/Commands/LibraryCommands.cs:86-91`
+
+**Step 1: Add batch-update and batch-map subcommands**
+
+In `LibraryCommands.cs`, replace lines 86-91 with:
+
+```csharp
+        libraryCommand.Add(listCmd);
+        libraryCommand.Add(mapCmd);
+        libraryCommand.Add(suggestCmd);
+        libraryCommand.Add(CreateBatchUpdate(dbOption));
+        libraryCommand.Add(CreateBatchMap(dbOption));
+
+        return libraryCommand;
+    }
+```
+
+Then add these two static methods before the `Truncate` method:
+
+```csharp
+    private static Command CreateBatchUpdate(Option<string> dbOption)
+    {
+        var cmd = new Command("batch-update", "Bulk update library status");

+# Unit Test Audit Extension Design
+
+## Goal
+
+Extend the PortTracker `audit` command to classify unit tests (not just features) by inspecting .NET test source code with Roslyn.
+
+## Architecture
+
+Parameterize the existing audit pipeline (`AuditCommand` + `SourceIndexer` + `FeatureClassifier`) to support both `features` and `unit_tests` tables. No new files — the same indexer and classifier logic applies to test methods.
+
+## CLI Interface
+
+```
+dotnet run -- audit --type features|tests|all [--source <path>] [--module <id>] [--execute]
+```
+
+| Flag | Default (features) | Default (tests) |
+|------|-------------------|-----------------|
+| `--type` | `features` | — |
+| `--source` | `dotnet/src/ZB.MOM.NatsNet.Server` | `dotnet/tests/ZB.MOM.NatsNet.Server.Tests` |
+| `--output` | `reports/audit-results.csv` | `reports/audit-results-tests.csv` |
+
+- `--type all` runs both sequentially.
+- `--source` override works for either type.
+
+## Changes Required
+
+### AuditCommand.cs
+
+1. Add `--type` option with values `features`, `tests`, `all`.
+2. Thread an `AuditTarget` (table name + default source + default output + display label) through `RunAudit` and `ApplyUpdates`.
+3. `--type all` calls `RunAudit` twice with different targets.
+4. `ApplyUpdates` uses the target's table name in UPDATE SQL.
+
+### FeatureClassifier.cs
+
+No changes. Same N/A lookup and classification logic applies to unit tests.
+
+### SourceIndexer.cs
+
+No changes. Already generic — just pass a different directory path.
+
+## Pre-audit DB Reset
+
+Before running the test audit, manually reset deferred tests to `unknown`:
+
+```sql
+sqlite3 porting.db "UPDATE unit_tests SET status = 'unknown' WHERE status = 'deferred';"
+```
+
+## Execution Sequence
+
+1. Reset deferred tests: `sqlite3 porting.db "UPDATE unit_tests SET status = 'unknown' WHERE status = 'deferred';"`
+2. Run audit: `dotnet run -- audit --type tests --db porting.db --execute`
+3. Verify results and generate report.
+
+## Classification Behavior for Tests
+
+Same priority as features:
+1. **N/A**: Go method matches logging/signal patterns → `n_a`
+2. **Method found**: Test class + method exists in test project → `verified` or `stub`
+3. **Class exists, method missing**: → `deferred` ("method not found")
+4. **Class not found**: → `deferred` ("class not found")
