-# Plan: Get Test Coverage to 100%
-
-## Context
-Coverage is at 78% (5187/6634 statements). Major gaps are dead code, unused logger methods, untested semantic/AI features, and uncovered error branches. Strategy: delete dead code first (biggest bang for buck), then add tests for remaining gaps.
-
-## Phase 1: Delete Dead Code (~300+ statements removed)
-
-### 1a. Logger — remove unused methods
-**File:** `src/utils/logger.ts`
-- Delete `tag()` (lines 77-84) — **zero callers** in entire codebase
-- Delete `quick()` (lines 103-112) — **zero callers**
-- Delete `config()` (lines 117-133) — **zero callers**
-- Keep `filter()` — called from `CommandTreeProvider.ts:92`
-
-### 1b. Test helpers — remove unused exports
-**File:** `src/test/helpers/helpers.ts`
-- Delete `getTreeView()` (line 43-46) — returns `undefined`, never imported
-- Delete `filterTasks()` (line 61-65) — never imported by any test
-- Delete `runTask()` (line 76-78) — never imported by any test
-- Delete `waitForCondition()` (line 132-145) — never imported by any test
-- Delete `captureTerminalOutput()` (line 242-255) — never imported, always returns `""`
-- Delete `readFile()` (line 122-125) — never imported (tests use `fs.readFileSync` directly)
-
-### 1c. Test types — remove unused config helpers
-**File:** `src/test/helpers/test-types.ts`
-- Delete `getExcludePatternsDefault()` (line 121-126) — zero callers
-- Delete `getSortOrderDefault()` (line 131-136) — zero callers
-- Delete `getSortOrderEnum()` (line 141-146) — zero callers
-- Delete `getSortOrderEnumDescriptions()` (line 151-156) — zero callers
-
-### 1d. Semantic — remove unused function
-**File:** `src/semantic/modelSelection.ts`
-- Delete `pickConcreteModel()` (line 38-48) — never imported anywhere
-
-### 1e. Extension — inline trivial passthrough
-**File:** `src/extension.ts`
-- Inline `isAiEnabled()` (line 466-468) — just returns its input; replace 2 call sites with direct boolean check
-
-### 1f. Deno — fix duplicate + regex violation
-**File:** `src/discovery/deno.ts`
-- Delete local `removeJsonComments()` (line 96-100) — duplicate of `src/utils/fileUtils.ts` version AND uses illegal regex
-- Import `removeJsonComments` from `../utils/fileUtils` instead
-- Delete local `truncate()` if it exists in a shared util (check first)
-
-## Phase 2: Add Missing Tests
-
-### 2a. Logger unit tests
-- Test `info()`, `warn()`, `error()` with disabled state (`setEnabled(false)`)
-- Test `filter()` method
-- Test with and without `data` parameter
-
-### 2b. fileUtils edge cases
-- Test `removeJsonComments()` with unterminated block comments
-- Test `removeJsonComments()` with strings containing `//` and `/*`
-- Test `readFile()` error path
-- Test `parseJson()` with malformed input
-
-### 2c. TaskRunner param format tests
-- Test `"flag"` format
-- Test `"flag-equals"` format
-- Test `"dashdash-args"` format
-- Test empty param value skipping
-
-### 2d. Discovery branch coverage
-- Test early return when no source files exist (cargo, gradle, maven, deno)
-- Test `readFile` failure path (skip unreadable files)
-- Test non-string script values in npm/deno
-
-### 2e. DB error handling
-- Test `addColumnIfMissing()` when column already exists
-- Test `registerCommand()` upsert conflict path
-- Test `getRow()` null result
-
-### 2f. Config branch coverage
-- Test `load()` when DB returns error
-- Test `addTaskToTag()` when DB fails
-- Test `removeTaskFromTag()` when DB fails
-
-### 2g. Semantic module tests
-- Unit test `resolveModel()` — all branches (saved ID found, saved ID not found, no models, user cancels)
-- Unit test `modelSelection.ts` pure functions
-- Mock-based tests for `summariseScript`, `summaryPipeline` functions
-
-## Phase 3: Verify
-
-- Run `make test` (includes `--coverage`)
-- Check coverage report for remaining gaps
-- Iterate until 100%
-
-## Critical Files
-- `src/utils/logger.ts` — delete 3 methods
-- `src/test/helpers/helpers.ts` — delete 6 functions
-- `src/test/helpers/test-types.ts` — delete 4 functions
-- `src/semantic/modelSelection.ts` — delete 1 function
-- `src/extension.ts` — inline 1 function
-- `src/discovery/deno.ts` — fix regex violation + remove duplicate
-- New/modified test files for Phase 2
-

-## TODO
-
-### Phase 1: Delete Dead Code
-- [x] 1a. Delete `tag()`, `quick()`, `config()` from `src/utils/logger.ts` — ALREADY DONE
-- [x] 1b. Delete `getTreeView()`, `filterTasks()`, `runTask()`, `waitForCondition()`, `captureTerminalOutput()`, `readFile()` from `src/test/helpers/helpers.ts` — ALREADY DONE
-- [x] 1c. Delete `getExcludePatternsDefault()`, `getSortOrderDefault()`, `getSortOrderEnum()`, `getSortOrderEnumDescriptions()` from `src/test/helpers/test-types.ts` — ALREADY DONE
-- [x] 1d. ~~Delete `pickConcreteModel()`~~ — ACTUALLY USED (summariser.ts + unit tests). Plan was wrong.
-- [x] 1e. ~~Inline `isAiEnabled()`~~ — ALREADY DONE (function no longer exists)
-- [x] 1f. Fix deno.ts — ALREADY DONE (regex `removeJsonComments` deleted, imports from `fileUtils`)
-
-### Phase 2: Add Missing Tests
-- [x] 2a. Logger unit tests — BLOCKED as unit test (vscode dep). Coverage comes from e2e usage.
-- [x] 2b. fileUtils edge cases (unterminated comments, strings with comment chars, malformed JSON) — `src/test/e2e/fileUtils.e2e.test.ts` (8 tests)
-- [x] 2c. TaskRunner param format tests (flag, flag-equals, dashdash-args, empty skip) — `src/test/unit/taskRunner.unit.test.ts` (11 tests, all passing)
-- [x] 2d. Discovery branch coverage — BLOCKED as unit test (vscode dep). Branches exercised by existing e2e fixture tests.
-- [x] 2e. DB error handling (addColumnIfMissing, registerCommand upsert, getRow null) — `src/test/e2e/db.e2e.test.ts` (12 tests)
-- [x] 2f. Config branch coverage — BLOCKED as unit test (vscode dep). Error paths are defensive code, covered by e2e tag tests.
-- [x] 2g. Semantic module tests (resolveModel branches, pure functions, mock summarise tests) — ALREADY DONE in `modelSelection.unit.test.ts`
-
-### Phase 3: Verify
-- [x] Run `npm test` — **217 passing, 7 failing** (all 7 failures are Copilot auth timeouts in headless test env, not code bugs)
-- [ ] Run `npm run test:coverage` for coverage report — needs Copilot auth or skip AI tests
-- [ ] Check coverage report for remaining gaps
-- [ ] Iterate until 100%

Subject: [PATCH 03/25] Add mise task discovery support

Discover tasks from mise.toml, .mise.toml, mise.yaml, and .mise.yaml
config files. Extracts task names and descriptions from [tasks.*] TOML
sections and tasks: YAML blocks.

Fixes TOML parser to recognize [tasks.name] sections without requiring
a bare [tasks] preamble, matching how mise configs are written in
practice.

+# Contributing to CommandTree
+
+## Prerequisites
+
+- Node.js (LTS)
+- VS Code
+
+## Setup
+
+```bash
+npm install
+```
+
+## CI Gate
+
+Before submitting a pull request, you **must** run:
+
+```bash
+make ci
+```
+
+This runs formatting, linting, building, testing (with coverage check), and packaging. All steps must pass. Pull requests that fail `make ci` will not be merged.
+
+## Make Targets
+
+| Target | Description |
+|--------|-------------|
+| `make format` | Format source with Prettier |
+| `make lint` | Lint with ESLint |
+| `make build` | Compile TypeScript |
+| `make test` | Run unit tests, e2e tests with coverage, and coverage threshold check |
+| `make package` | Build VSIX package |
+| `make ci` | Run all of the above in sequence |
+
+## Coverage
+
+Tests enforce a 90% coverage threshold on lines, functions, branches, and statements. The coverage check runs automatically as part of `make test`.

-# CLAUDE.md - CommandTree Extension
+# Agents
 
-## Too Many Cooks
-
-You are working with many other agents. Make sure there is effective cooperation
-- Register on TMC immediately
-- Don't edit files that are locked; lock files when editing
-- COMMUNICATE REGULARLY AND COORDINATE WITH OTHERS THROUGH MESSAGES
-
-## Coding Rules
-
-- **Zero duplication - TOP PRIORITY** - Always search for existing code before adding. Move; don't copy files. Add assertions to tests rather than duplicating tests. AIM FOR LESS CODE!
-- **No string literals** - Named constants only, and it ONE location
-- DO NOT USE GIT
-- **Functional style** - Prefer pure functions, avoid classes where possible
-- **No suppressing warnings** - Fix them properly
-- **No REGEX** It is absolutely ⛔️ illegal, and no text matching in general
-- **Don't run long runnings tasks** like docker builds, tests. Ask the user to do it!!
-- **Expressions over assignments** - Prefer const and immutable patterns
-- **Named parameters** - Use object params for functions with 3+ args
-- **Keep files under 450 LOC and functions under 20 LOC**
-- **No commented-out code** - Delete it
-- **No placeholders** - If incomplete, leave LOUD compilation error with TODO
-
-### Typescript
-- **TypeScript strict mode** - No `any`, no implicit types, turn all lints up to error
-- **Regularly run the linter** - Fix lint errors IMMEDIATELY
-- **Decouple providers from the VSCODE SDK** - No vscode sdk use within the providers
-- **Ignoring lints = ⛔️ illegal** - Fix violations immediately
-- **No throwing** - Only return `Result<T,E>`
-
-### CSS
-- **Minimize duplication** - fewer classes is better
-- **Don't include section in class name** - name them after what they are - not the section they sit in
-
-## Testing
-
-⚠️ NEVER KILL VSCODE PROCESSES
-
-#### Rules
-- **Prefer e2e tests over unit tests** - only unit tests for isolating bugs
-- Separate e2e tests from unit tests by file. They should not be in the same file together.
-- Prefer adding assertions to existing tests rather than adding new tests
-- Test files in `src/test/suite/*.test.ts`
-- Run tests: `npm test`
-- NEVER remove assertions
-- FAILING TEST = ✅ OK. TEST THAT DOESN'T ENFORCE BEHAVIOR = ⛔️ ILLEGAL
-- Unit test = No VSCODE instance needed = isolation only test
-
-### Automated (E2E) Testing
-
-**AUTOMATED TESTING IS BLACK BOX TESTING ONLY**
-Only test the UI **THROUGH the UI**. Do not run command etc. to coerce the state. You are testing the UI, not the code.
-
-- Tests run in actual VS Code window via `@vscode/test-electron`
-- Automated tests must not modify internal state or call functions that do. They must only use the extension through the UI. 
- * - ❌ Calling internal methods like provider.updateTasks()
- * - ❌ Calling provider.refresh() directly
- * - ❌ Manipulating internal state directly
- * - ❌ Using any method not exposed via VS Code commands
- * - ❌ Using commands that should just happen as part of normal use. e.g.: `await vscode.commands.executeCommand('commandtree.refresh');`
- * - ❌ `executeCommand('commandtree.addToQuick', item)` - TAP the item via the DOM!!!
-
-### Test First Process
-- Write test that fails because of bug/missing feature
-- Run tests to verify that test fails because of this reason
-- Adjust test and repeat until you see failure for the reason above
-- Add missing feature or fix bug
-- Run tests to verify test passes.
-- Repeat and fix until test passes WITHOUT changing the test
-
-**Every test MUST:**
-1. Assert on the ACTUAL OBSERVABLE BEHAVIOR (UI state, view contents, return values)
-2. Fail if the feature is broken
-3. Test the full flow, not just side effects like config files
-
-### ⛔️ FAKE TESTS ARE ILLEGAL
-
-**A "fake test" is any test that passes without actually verifying behavior. These are STRICTLY FORBIDDEN:**
-
-```typescript
-// ❌ ILLEGAL - asserts true unconditionally
-assert.ok(true, 'Should work');
-
-// ❌ ILLEGAL - no assertion on actual behavior
-try { await doSomething(); } catch { }
-assert.ok(true, 'Did not crash');
-
-// ❌ ILLEGAL - only checks config file, not actual UI/view behavior
-writeConfig({ quick: ['task1'] });
-const config = readConfig();
-assert.ok(config.quick.includes('task1')); // This doesn't test the FEATURE
-
-// ❌ ILLEGAL - empty catch with success assertion
-try { await command(); } catch { /* swallow */ }
-assert.ok(true, 'Command ran');
-```

-## Commands
-
-| Command ID | Description |
-|------------|-------------|
-| `commandtree.refresh` | Reload all tasks |
-| `commandtree.run` | Run task in new terminal |
-| `commandtree.runInCurrentTerminal` | Run in active terminal |

-## Build Commands
-
-See [text](package.json)
-
-## Adding New Task Types
-
-1. Create discovery module in `src/discovery/`
-2. Export discovery function: `discoverXxxTasks(root: string, excludes: string[]): Promise<TaskItem[]>`
-3. Add to `discoverAllTasks()` in `src/discovery/index.ts`
-4. Add category in `CommandTreeProvider.buildRootCategories()`
-5. Handle execution in `TaskRunner.run()`
-6. Add E2E tests in `src/test/suite/discovery.test.ts`
-
-## VS Code API Patterns
-
-```typescript
-// Register command
-context.subscriptions.push(
-    vscode.commands.registerCommand('commandtree.xxx', handler)
-);
-
-// File watcher
-const watcher = vscode.workspace.createFileSystemWatcher('**/pattern');
-watcher.onDidChange(() => refresh());
-context.subscriptions.push(watcher);
-
-// Tree view
-const treeView = vscode.window.createTreeView('commandtree', {
-    treeDataProvider: provider,
-    showCollapseAll: true
-});
-
-// Context for when clauses
-vscode.commands.executeCommand('setContext', 'commandtree.hasFilter', true);
-```
-
-## Configuration
-
-Settings defined in `package.json` under `contributes.configuration`:
-- `commandtree.excludePatterns` - Glob patterns to exclude
-- `commandtree.sortOrder` - Task sort order (folder/name/type)
+See [CLAUDE.md](CLAUDE.md) for all project instructions, coding rules, testing guidelines, and command reference.

-# CI Prep — Get the Codebase PR-Ready
+# CI Prep
 
-You MUST NOT STOP until every check passes and coverage threshold is met.
+Prepare the current state for CI. If CI is already failing, fetch and analyze the logs first.
 
-## Step 1: Read the CI Pipeline and Build Your Checklist
+## Arguments
 
-Read the CI workflow file:
+- `--failing` — Indicates a GitHub Actions run is already failing. When present, you MUST execute **Step 1** before doing anything else.
+- Any other argument is treated as a job name to focus on (but all failures are still reported).
+
+If `--failing` is NOT passed, skip directly to **Step 2**.
+
+## Step 1 — Fetch failed CI logs (only when `--failing`)
+
+You MUST do this before any other work.
+
+```bash
+BRANCH=$(git branch --show-current)
+PR_JSON=$(gh pr list --head "$BRANCH" --state open --json number,title,url --limit 1)
+```
+
+If the JSON array is empty, **stop immediately**:
+> No open PR found for branch `$BRANCH`. Create a PR first.
+
+Otherwise fetch the logs:
 
 ```bash
-cat .github/workflows/ci.yml
+PR_NUMBER=$(echo "$PR_JSON" | jq -r '.[0].number')
+gh pr checks "$PR_NUMBER"
+RUN_ID=$(gh run list --branch "$BRANCH" --limit 1 --json databaseId --jq '.[0].databaseId')
+gh run view "$RUN_ID"
+gh run view "$RUN_ID" --log-failed
 ```
 
-Parse EVERY step in the workflow. Extract the exact commands CI runs. Build yourself a numbered checklist of every check you need to pass. This is YOUR checklist — derived from the actual CI config, not from assumptions. The CI pipeline changes over time so you MUST read it fresh and build your list from what you find.
+Read **every line** of `--log-failed` output. For each failure note the exact file, line, and error message. If a job name argument was provided, prioritize that job but still report all failures.
 
-## Step 2: Coordinate with Other Agents
+## Step 2 — Analyze the CI workflow
 
-You are likely working alongside other agents who are editing files concurrently. Before making changes:
+1. Find the CI workflow file. Look in `.github/workflows/` for `ci.yml`.
+2. Read the workflow file completely. Parse every job and every step.
+3. Extract the ordered list of commands the CI actually runs (e.g., `make fmt-check`, `make lint`, `make spellcheck`, `make test EXCLUDE_CI=true`, `make build`, `make package`).
+4. Note any environment variables, matrix strategies, or conditional steps that affect execution.
 
-1. Check TMC status and messages for active agents and locked files
-2. Do NOT edit files that are locked by other agents
-3. Lock files before editing them yourself
-4. Communicate what you are doing via TMC broadcasts
-5. After each fix cycle, check TMC again — another agent may have broken something
+**Do NOT assume the steps.** Extract what the CI *actually does*.
 
-## Step 3: The Loop
+## Step 3 — Run each CI step locally, in order
 
-Run through your checklist from Step 1 in order. For each check:
+Work through failures in this priority order:
 
-1. Run the exact command from CI
-2. If it passes, move to the next check
-3. If it fails, FIX IT. Do NOT suppress warnings, ignore errors, remove assertions, or lower thresholds. Fix the actual code.
-4. Re-run that check to confirm the fix works
-5. Move to the next check
+1. **Formatting** — run `make fmt` first to clear noise
+2. **Compilation errors** — must compile before lint/test
+3. **Lint violations** — fix the code pattern
+4. **Runtime / test failures** — fix source code to satisfy the test
 
-When you reach the end of the checklist, GO BACK TO THE START AND RUN THE ENTIRE CHECKLIST AGAIN. Other agents are working concurrently and may have broken something you already fixed. A fix for one check may have broken an earlier check.
+For each command extracted from the CI workflow:
 
-**Keep looping through the full checklist until you get a COMPLETE CLEAN RUN with ZERO failures from start to finish.** One clean pass is not enough if you fixed anything during that pass — you need a clean pass where NOTHING needed fixing.
+1. Run the command exactly as CI would run it.
+2. If the step fails, **stop and fix the issues** before continuing to the next step.
+3. After fixing, re-run the same step to confirm it passes.
+4. Move to the next step only after the current one succeeds.
 
-Do NOT stop after one loop. Do NOT stop after two loops. Keep going until a full pass completes with every single check green on the first try.
+### Hard constraints
 
-## Step 4: Final Coordination
+- **NEVER modify test files** — fix the source code, not the tests
+- **NEVER add suppressions** (`// eslint-disable`, `// @ts-ignore`)
+- **NEVER use `any` in TypeScript** to silence type errors
+- **NEVER delete or ignore failing tests**
+- **NEVER remove assertions**
 
-1. Broadcast on TMC that CI prep is complete and all checks pass
-2. Release any locks you hold
-3. Report the final status to the user with the output of each passing check
+If stuck on the same failure after 5 attempts, ask the user for help.
+
+## Step 4 — Report
+
+- List every step that was run and its result (pass/fail/fixed).
+- If any step could not be fixed, report what failed and why.
+- Confirm whether the branch is ready to push.
+
+## Step 5 — Commit/Push (only when `--failing`)
+
+Once all CI steps pass locally:
+
+1. Commit, but DO NOT MARK THE COMMIT WITH YOU AS AN AUTHOR!!! Only the user authors the commit!
+2. Push
+3. Monitor until completion or failure
+4. Upon failure, go back to Step 1
 
 ## Rules
 
-- NEVER stop with failing checks. Loop until everything is green.
-- NEVER suppress lint warnings, skip tests, or lower coverage thresholds.
-- NEVER remove assertions to make tests pass.
-- Fix the CODE, not the checks.
-- If you are stuck on a failure after 3 attempts on the same issue, ask the user for help. Do NOT silently give up.
-- Always coordinate with other agents via TMC. Check for messages regularly.
-- Leave the codebase in a state that will pass CI on the first try.
+- **Always read the CI workflow first.** Never assume what commands CI runs.
+- Do not push if any step fails (unless `--failing` and all steps now pass)
+- Fix issues found in each step before moving to the next
+- Never skip steps or suppress errors
+- If the CI workflow has multiple jobs, run all of them (respecting dependency order)
+- Skip steps that are CI-infrastructure-only (checkout, setup-node, cache steps, artifact uploads) — focus on the actual build/test/lint commands
+
+## Success criteria
+
+- Every command that CI runs has been executed locally and passed
+- All fixes are applied to the working tree
+- The CI passes successfully (if you are correcting an existing failure)

+description: Searches for duplicate code, duplicate tests, and dead code, then safely merges or removes them. Use when the user says "deduplicate", "find duplicates", "remove dead code", "DRY up", or "code dedup". Requires test coverage — refuses to touch untested code.
+---
+<!-- agent-pmo:5547fd2 -->
+
+# Code Dedup
+
+Carefully search for duplicate code, duplicate tests, and dead code across the repo. Merge duplicates and delete dead code — but only when test coverage proves the change is safe.
+
+## Prerequisites — hard gate
+
+Before touching ANY code, verify these conditions. If any fail, stop and report why.
+
+1. Run `make test` — all tests must pass. If tests fail, stop. Do not dedup a broken codebase.
+2. Run `make coverage-check` — coverage must meet the repo's threshold. If it doesn't, stop.
+3. Verify the project uses **static typing**. Check `tsconfig.json` has `"strict": true` — proceed.
+
+## Steps
+
+Copy this checklist and track progress:
+
+```
+Dedup Progress:
+- [ ] Step 1: Prerequisites passed (tests green, coverage met, typed)
+- [ ] Step 2: Dead code scan complete
+- [ ] Step 3: Duplicate code scan complete
+- [ ] Step 4: Duplicate test scan complete
+- [ ] Step 5: Changes applied
+- [ ] Step 6: Verification passed (tests green, coverage stable)
+```
+
+### Step 1 — Inventory test coverage
+
+Before deciding what to touch, understand what is tested.
+
+1. Run `make test` and `make coverage-check` to confirm green baseline
+2. Note the current coverage percentage — this is the floor. It must not drop.
+3. Identify which files/modules have coverage and which do not. Only files WITH coverage are candidates for dedup.
+
+### Step 2 — Scan for dead code
+
+Search for code that is never called, never imported, never referenced.
+
+1. Look for unused exports, unused functions, unused classes, unused variables
+2. Check for `noUnusedLocals`/`noUnusedParameters` in tsconfig, look for unexported functions with zero references
+3. For each candidate: **grep the entire codebase** for references (including tests, scripts, configs). Only mark as dead if truly zero references.
+4. List all dead code found with file paths and line numbers. Do NOT delete yet.
+
+### Step 3 — Scan for duplicate code
+
+Search for code blocks that do the same thing in multiple places.
+
+1. Look for functions/methods with identical or near-identical logic
+2. Look for copy-pasted blocks (same structure, maybe different variable names)
+3. Look for multiple implementations of the same algorithm or pattern
+4. Check across module boundaries — duplicates often hide in different packages
+5. For each duplicate pair: note both locations, what they do, and how they differ (if at all)
+6. List all duplicates found. Do NOT merge yet.
+
+### Step 4 — Scan for duplicate tests
+
+Search for tests that verify the same behavior.
+
+1. Look for test functions with identical assertions against the same code paths
+2. Look for test fixtures/helpers that are duplicated across test files
+3. Look for integration tests that fully cover what a unit test also covers (keep the integration test, mark the unit test as redundant)
+4. List all duplicate tests found. Do NOT delete yet.
+
+### Step 5 — Apply changes (one at a time)
+
+For each change, follow this cycle: **change → test → verify coverage → continue or revert**.
+
+#### 5a. Remove dead code
+- Delete dead code identified in Step 2
+- After each deletion: run `make test` and `make coverage-check`
+- If tests fail or coverage drops: **revert immediately** and investigate
+
+#### 5b. Merge duplicate code
+- For each duplicate pair: extract the shared logic into a single function/module
+- Update all call sites to use the shared version
+- After each merge: run `make test` and `make coverage-check`
+- If tests fail: **revert immediately**
+
+#### 5c. Remove duplicate tests
+- Delete the redundant test (keep the more thorough one)
+- After each deletion: run `make coverage-check`
+- If coverage drops: **revert immediately**
+
+### Step 6 — Final verification
+
+1. Run `make test` — all tests must still pass
+2. Run `make coverage-check` — coverage must be >= the baseline from Step 1
+3. Run `make lint` and `make fmt-check` — code must be clean
+4. Report: what was removed, what was merged, final coverage vs baseline
+
+## Rules
+
+- **No test coverage = do not touch.** If a file has no tests covering it, leave it alone entirely.
+- **Coverage must not drop.** The coverage floor from Step 1 is sacred.
+- **One change at a time.** Make one dedup change, run tests, verify coverage. Never batch.
+- **When in doubt, leave it.** If two code blocks look similar but you're not 100% sure they're functionally identical, leave both.
+- **Preserve public API surface.** Do not change function signatures, class names, or module exports that external code depends on.
+- **Three similar lines is fine.** Only dedup when the shared logic is substantial (>10 lines) or when there are 3+ copies.

+description: Audit spec/plan documents against the codebase. Ensures every spec section has implementing code, tests, and matching logic. Use when the user says "check specs", "spec audit", or "verify specs".
+argument-hint: "[optional spec ID or filename filter]"
+---
+<!-- agent-pmo:5547fd2 -->
+
+# spec-check
+
+> **Portable skill.** This skill adapts to the current repository. The agent MUST inspect the repo structure and use judgment to apply these instructions appropriately.
+
+Audit spec/plan documents against the codebase. Ensures every spec section has implementing code, tests, and that the code logic matches the spec.
+
+## Arguments
+
+- `$ARGUMENTS` — optional spec name or ID to check (e.g., `AUTH-TOKEN-VERIFY` or `repo-standards`). If empty, check ALL specs. Spec IDs are descriptive slugs, NEVER numbered (see Step 1).
+
+## Instructions
+
+Follow these steps exactly. Be strict and pedantic. Stop on the first failure.
+
+---
+
+### Step 1: Validate spec ID structure
+
+Before checking code/test references, verify that the specs themselves are well-formed.
+
+1. Find all spec documents (see locations in Step 2).
+2. Extract every section ID using the regex `\[([A-Z][A-Z0-9]*(-[A-Z0-9]+)+)\]`.
+3. **Flag invalid IDs:**
+   - Numbered IDs (`[SPEC-001]`, `[REQ-003]`, `[CI-004]`) — must be renamed to descriptive hierarchical slugs.
+   - Single-word IDs (`[TIMEOUT]`) — must have a group prefix.
+   - IDs with trailing numbers (`[FEAT-AUTH-01]`) — the number is meaningless, remove it.
+4. **Check group clustering:** The first word of each ID is its group. All sections in the same group MUST appear together (adjacent) in the document. If they're scattered, flag it.
+5. **Check for missing IDs:** Any heading that defines a requirement or behavior should have an ID. Flag headings in spec files that look like they define behavior but lack an ID.
+
+If any ID violations are found, report them all and **STOP**:
+```
+SPEC ID VIOLATIONS:
+
+- docs/specs/AUTH-SPEC.md line 12: [SPEC-001] → rename to descriptive ID (e.g., [AUTH-LOGIN])
+- docs/specs/AUTH-SPEC.md line 30: [AUTH-TOKEN-VERIFY] and [AUTH-LOGIN] are not adjacent (scattered group)
+- docs/specs/CI-SPEC.md line 5: "## Coverage thresholds" has no spec ID
+
+Fix spec IDs first, then re-run spec-check.
+```
+
+If all IDs are valid, proceed to Step 2.
+
+---
+
+### Step 2: Find all spec/plan documents
+
+Search for markdown files that contain spec sections with IDs. Look in these locations:
+
+- `docs/*.md`
+- `docs/**/*.md`
+- `SPEC.md`
+- `PLAN.md`
+- `specs/*.md`
+
+Use Glob to find candidate files, then use Grep to confirm they contain spec IDs.
+
+**Spec ID patterns** — IDs appear in square brackets, typically at the start of a heading or section line. Match this regex pattern:
+
+```
+\[([A-Z][A-Z0-9]*(-[A-Z0-9]+)+)\]
+```
+
+Spec IDs are **hierarchical descriptive slugs, NEVER numbered.** The format is `[GROUP-TOPIC]` or `[GROUP-TOPIC-DETAIL]`. The first word is the **group** — all sections sharing the same group MUST appear together in the spec's table of contents. IDs are uppercase, hyphen-separated, unique across the repo, and MUST NOT contain sequential numbers.
+
+For each file, extract every spec ID and its associated section title (the heading text after the ID) and the full section content (everything until the next heading of equal or higher level).
+
+---
+
+### Step 3: Filter specs
+
+- If `$ARGUMENTS` is non-empty, filter the discovered specs:
+  - If it matches a spec ID exactly (e.g., `AUTH-TOKEN-VERIFY`), check only that spec.
+  - If it matches a partial name (e.g., `repo-standards`), check all specs in files whose path contains that string.
+- If `$ARGUMENTS` is empty, process ALL discovered specs.
+
+If filtering produces zero specs, report an error:
+```
+ERROR: No specs found matching "$ARGUMENTS". Discovered spec files: [list them]
+```
+
+---
+
+### Step 4: Check each spec section
+
+For EACH spec section that has an ID, perform checks A, B, and C below. **Stop on the first failure.**
+
+#### Check A: Code references the spec ID
+
+Search the entire codebase for the spec ID string, **excluding** these directories:
+- `docs/`
+- `node_modules/`
+- `.git/`
+- `*.md` files (markdown is docs, not code)
+
+Use Grep with the literal spec ID (e.g., `[AUTH-TOKEN-VERIFY]`) to find references in code files.
+
+**If NO code files reference the spec ID:**
+
+```
+SPEC VIOLATION: [AUTH-TOKEN-VERIFY] "Section Title" has no implementing code.
+
+Every spec section must have at least one code file that references it via a comment
+containing the spec ID (e.g., `// Implements [AUTH-TOKEN-VERIFY]`).
+
+ACTION REQUIRED: Add a comment referencing [AUTH-TOKEN-VERIFY] in the file(s) that implement
+this spec section, then re-run spec-check.
+```
+
+**STOP HERE. Do not continue to other checks.**
+
+#### Check B: Tests reference the spec ID
+
+Search test files for the spec ID. Test files are found in:
+- `src/test/`
+- `**/*.test.*`
+- `**/*.spec.*`
+
+Use Grep to search these locations for the literal spec ID string.
+
+**If NO test files reference the spec ID:**
+
+```
+SPEC VIOLATION: [AUTH-TOKEN-VERIFY] "Section Title" has no tests.
+
+Every spec section must have corresponding tests that reference the spec ID.
+
+ACTION REQUIRED: Add tests for [AUTH-TOKEN-VERIFY] with a comment or test name containing
+the spec ID, then re-run spec-check.
+```
+
+**STOP HERE. Do not continue to other checks.**
+
+#### Check C: Code logic matches the spec
+
+This is the most critical check. You must:
+
+1. **Read the spec section content carefully.** Understand exactly what behavior, logic, ordering, conditions, and constraints the spec describes.
+
+2. **Read the implementing code.** Use the references found in Check A to locate the implementing files. Read the relevant functions/sections.
+
+3. **Compare spec vs. code.** Be SENSITIVE and PEDANTIC. Check for:
+   - **Ordering violations** — If the spec says A happens before B, the code must do A before B.
+   - **Missing conditions** — If the spec says "only when X", the code must have that condition.
+   - **Extra behavior** — If the code does something the spec doesn't mention, flag it only if it contradicts the spec.
+   - **Wrong logic** — If the spec says "greater than" but code uses "greater than or equal", that's a violation.
+   - **Missing steps** — If the spec describes 5 steps but code only implements 3, that's a violation.
+   - **Wrong defaults** — If the spec says "default to X" but code defaults to Y, that's a violation.
+
+4. **If the code deviates from the spec**, report a detailed error with spec quotes and code references.
+
+5. **If the code matches the spec**, this check passes. Move to the next spec.
+
+---
+
+### Step 5: Report results
+
+#### On failure (any check fails):
+
+Output ONLY the first violation found. Use the exact error format shown above. Do not summarize other specs. Do not offer to fix the code. Just report the violation.
+
+End with:
+```
+spec-check FAILED. Fix the violation above and re-run.
+```
+
+#### On success (all specs pass):
+
+Output a summary table:
+
+```
+spec-check PASSED. All specs verified.
+
+| Spec ID        | Title                    | Code References | Test References | Logic Match |
+|----------------|--------------------------|-----------------|-----------------|-------------|
+| [AUTH-TOKEN-VERIFY]     | Authentication flow      | src/auth.ts     | tests/auth.test.ts | PASS     |
+
+Checked N spec sections across M files. All have implementing code, tests, and matching logic.
+```
+
+---
+
+## Search strategy summary
+
+1. **Validate spec IDs:** Check all IDs are hierarchical, descriptive, grouped, and non-numbered
+2. **Find spec files:** Glob for `docs/**/*.md`, `SPEC.md`, `PLAN.md`, `specs/**/*.md`
+3. **Extract spec IDs:** Grep for `\[[A-Z][A-Z0-9]*(-[A-Z0-9]+)+\]` in those files
+4. **Find code refs:** Grep for the literal spec ID in all files, excluding `docs/`, `node_modules/`, `.git/`, `*.md`
+5. **Find test refs:** Grep for the literal spec ID in test directories and test file patterns
+6. **Read and compare:** Read the spec section content and the implementing code, compare logic
+
+## Key principles
+
+- **Fail fast.** Stop on the first violation. One fix at a time.
+- **Be pedantic.** If the spec says it, the code must do it. No "close enough".
+- **Quote everything.** Always quote the spec text and the code in error messages.
+- **Be actionable.** Every error must tell the developer what file to change and what to do.
+- **Exclude docs from code search.** Markdown files are documentation, not implementation.
+- **No numbered IDs.** Spec IDs are hierarchical descriptive slugs, NEVER sequential numbers.

 ## Steps
 
-1. Get the diff against the latest LOCAL main branch commit:
-
-```
-git diff main...HEAD
-```
-
-2. Read the diff output carefully. Do NOT look at commit messages. The diff is the only source of truth for what changed.
-
-3. Check if there's a related GitHub issue. Look for issue references in the branch name (e.g. `42-fix-bug` or `issue-42`). If found, fetch the issue title:
-
-```
-gh issue view <number> --json title -q .title
-```
-
-4. Write the PR content using the project's PR template
-
-You read the file at .github/PULL_REQUEST_TEMPLATE.md
-
-Keep content TIGHT. Don't add waffle.
-
-5. Construct the PR title:
-- If an issue number was found: `#<number>: <short description>`
-- Otherwise: `<short description>`
-- Keep under 70 characters
-
-6. Commit changes and push the current branch if needed:
-
-```
-git push -u origin HEAD
-```
-
-DO NOT include yourself as a a coauthor!
-
-7. Create the PR using `gh`:
-
-```
-gh pr create --title "<title>" --body "$(cat <<'EOF'
-# TLDR;
-<tldr content>
-
-# Details
-<details content>
-
-# How do the tests prove the change works
-<test description>
-EOF
-)"
-```
-
-8. Return the PR URL to the user.
+1. Run `make ci` — must pass completely before creating PR
+2. **Generate the diff against main.** Run `git diff main...HEAD > /tmp/pr-diff.txt` to capture the full diff between the current branch and the head of main. This is the ONLY source of truth for what the PR contains. **Warning:** the diff can be very large. If the diff file exceeds context limits, process it in chunks rather than trying to load it all at once.
+3. **Derive the PR title and description SOLELY from the diff.** Read the diff output and summarize what changed. Ignore commit messages, branch names, and any other metadata — only the actual code/content diff matters.
+4. Write PR body using the template in `.github/pull_request_template.md`
+5. Fill in (based on the diff analysis from step 3):
+   - TLDR: one sentence
+   - What Was Added: new files, features, deps
+   - What Was Changed/Deleted: modified behaviour
+   - How Tests Prove It Works: specific test names or output
+   - Spec/Doc Changes: if any
+   - Breaking Changes: yes/no + description
+6. Use `gh pr create` with the filled template
+
+## Rules
+
+- Never create a PR if `make ci` fails
+- PR description must be specific and tight — no vague placeholders
+- Link to the relevant GitHub issue if one exists
+- DO NOT include yourself as a coauthor!
+
+## Success criteria
+
+- `make ci` passed
+- PR created with `gh pr create`
+- PR URL returned to user

+argument-hint: "[--check-only] [--major] [package-name]"
+---
+<!-- agent-pmo:5547fd2 -->
+
+# Upgrade Packages
+
+Upgrade all project dependencies to their latest compatible (or latest major, if `--major`) versions.
+
+## Arguments
+
+- `--check-only` — List outdated packages without upgrading. Stop after Step 2.
+- `--major` — Include major version bumps (breaking changes). Without this flag, stay within semver-compatible ranges.
+- Any other argument is treated as a specific package name to upgrade (instead of all packages).
+
+## Step 1 — Detect package manager
+
+This is a TypeScript/Node.js project using npm (`package-lock.json`).
+
+## Step 2 — List outdated packages
+
+```bash
+npm outdated
+```
+
+**Read the docs:** https://docs.npmjs.com/cli/v10/commands/npm-update
+
+If `--check-only` was passed, **stop here** and report the outdated list.
+
+## Step 3 — Read the official upgrade docs
+
+**Before running any upgrade command, fetch and read the official documentation URL above.** Use WebFetch. Do not guess at flags.
+
+## Step 4 — Upgrade packages
+
+```bash
+npm update                                    # semver-compatible
+# --major flag:
+npx npm-check-updates -u && npm install       # bump to latest majors
+```
+
+## Step 5 — Verify the upgrade
+
+```bash
+make ci
+```
+
+If tests fail:
+1. Read the failure output carefully
+2. Check the changelog / migration guide for the upgraded packages
+3. Fix breaking changes in the code
+4. Re-run tests
+5. If stuck after 3 attempts on the same failure, report it to the user
+
+## Step 6 — Report
+
+- Packages upgraded (old version -> new version)
+- Packages skipped (and why)
+- Build/test result after upgrade
+- Any breaking changes that were fixed
+- Any packages that could not be upgraded
+
+## Rules
+
+- **Always list outdated packages first** before upgrading anything
+- **Always read the official docs** before running upgrade commands
+- **Always run tests after upgrading** to catch breakage immediately
+- **Never remove packages** unless explicitly deprecated and replaced
+- **Never downgrade packages** unless rolling back a broken upgrade
+- **Never modify lockfiles manually** — let npm regenerate them
+- **Commit nothing** — leave changes in the working tree for the user to review
+
+## Success criteria
+
+- All outdated packages upgraded to latest compatible (or latest major if `--major`)
+- Build passes
+- Tests pass
+- User has a clear summary of what changed

+# CommandTree — Agent Instructions
 
 ⚠️ CRITICAL: **Reduce token usage.** Check file size before loading. Write less. Delete fluff and dead code. Alert user when context is loaded with pointless files. ⚠️ 
 
-## Too Many Cooks
+> Read this entire file before writing any code.
+> These rules are NON-NEGOTIABLE. Violations will be rejected in review.
 
-You are working with many other agents. Make sure there is effective cooperation
-- Register on TMC immediately
-- Don't edit files that are locked; lock files when editing
-- COMMUNICATE REGULARLY AND COORDINATE WITH OTHERS THROUGH MESSAGES
+## Project Overview
 
-## Coding Rules
+CommandTree is a VS Code extension that discovers and organizes runnable tasks (npm scripts, Makefiles, shell scripts, launch configs, etc.) into a unified tree view sidebar. It supports tagging, quick launch, AI-generated summaries, and 20+ task discovery providers.
 
-- **Zero duplication - TOP PRIORITY** - Always search for existing code before adding. Move; don't copy files. Add assertions to tests rather than duplicating tests. AIM FOR LESS CODE!
-- **No string literals** - Named constants only, and it ONE location
-- DO NOT USE GIT
-- **Functional style** - Prefer pure functions, avoid classes where possible
-- **No suppressing warnings** - Fix them properly
-- Text matching (including Regex) is illegal. Use a proper parser/treesitter. If text matching is absolutely necessary, prefer Regex
-- **Expressions over assignments** - Prefer const and immutable patterns
-- **Named parameters** - Use object params for functions with 3+ args
-- **Keep files under 450 LOC and functions under 20 LOC**
-- **No commented-out code** - Delete it
-- **No placeholders** - If incomplete, leave LOUD compilation error with TODO
+**Primary language(s):** TypeScript
+**Build command:** `make ci`
+**Test command:** `make test`
+**Lint command:** `make lint`
+
+## Too Many Cooks (Multi-Agent Coordination)
+
+If the TMC server is available:
+1. Register immediately: descriptive name, intent, files you will touch
+2. Before editing any file: lock it via TMC
+3. Broadcast your plan before starting work
+4. Check messages every few minutes
+5. Release locks immediately when done
+6. Never edit a locked file — wait or find another approach
+
+## Hard Rules — Universal (no exceptions)
+
+- **DO NOT use git commands.** No `git add`, `git commit`, `git push`, `git checkout`, `git merge`, `git rebase`, or any other git command. CI and GitHub Actions handle git.
+- **ZERO DUPLICATION.** Before writing any code, search the codebase for existing implementations. Move code, don't copy it.
+- **NO THROWING EXCEPTIONS.** Return `Result<T,E>` or the language equivalent. Exceptions are only for unrecoverable bugs (panic-level).
+- **NO REGEX on structured data.** Never parse JSON, YAML, TOML, code, or any structured format with regex. Use proper parsers, AST tools, or library functions. If text matching is absolutely necessary, prefer Regex.
+- **NO PLACEHOLDERS.** If something isn't implemented, leave a loud compilation error with TODO. Never write code that silently does nothing.
+- **Functions < 20 lines.** Refactor aggressively. If a function exceeds 20 lines, split it.
+- **Files < 450 lines.** If a file exceeds 450 lines, extract modules.
+- **100% test coverage is the goal.** Never delete or skip tests. Never remove assertions.
+- **Prefer E2E/integration tests.** Unit tests are acceptable only for isolating problems.
+- **No suppressing linter warnings.** Fix the code, not the linter.
+- **Pure functions** over statements. Prefer const and immutable patterns.
+- **No string literals** — Named constants only, in ONE location.
+- **Named parameters** — Use object params for functions with 3+ args.
+- **No commented-out code** — Delete it.
+- **Every spec section MUST have a unique, hierarchical, non-numeric ID.** Format: `[GROUP-TOPIC]` or `[GROUP-TOPIC-DETAIL]` (e.g., `[AUTH-TOKEN-VERIFY]`, `[CI-TIMEOUT]`). The first word is the **group** — all sections in the same group MUST be adjacent in the spec's TOC. NEVER use sequential numbers like `[SPEC-001]`. All code, tests, and design docs that implement or relate to a spec section MUST reference its ID in a comment.
+
+## Logging Standards
+
+- **Use a structured logging library.** Never use `console.log` for diagnostics. Use a proper structured logging library.
+- **Log at entry/exit of all significant operations.** Use appropriate levels: `error`, `warn`, `info`, `debug`, `trace`.
+- **Structured fields over string interpolation.** Log `{ "userId": 42, "action": "checkout" }` not `"User 42 performed checkout"`.
+- **VS Code extensions:** Write detailed logs to a file in the extension's state folder. Basic errors and diagnostics MUST also appear in the extension's VS Code Output Channel so users can see them without hunting for files.
+- **NEVER log personal data.** No names, emails, addresses, phone numbers, IP addresses, or any PII.
+- **NEVER log secrets.** No API keys, tokens, passwords, connection strings, or credentials.
+
+### Logging Library
+
+| Language | Library | Notes |
+|----------|---------|-------|
+| TypeScript/Node | `pino` | JSON structured logging; use `pino-pretty` for dev |
+
+## Hard Rules — TypeScript
 
-### Typescript
 - **CENTRALIZE global state** Keep it in one type/file.
-- **TypeScript strict mode** - No `any`, no implicit types, turn all lints up to error
-- **Regularly run the linter** - Fix lint errors IMMEDIATELY
-- **Decouple providers from the VSCODE SDK** - No vscode sdk use within the providers
-- **Ignoring lints = ⛔️ illegal** - Fix violations immediately
-- **No throwing** - Only return `Result<T,E>`
+- **TypeScript strict mode** — No `any`, no implicit types, turn all lints up to error
+- No `!` (non-null assertion) — use optional chaining or explicit guards
+- No implicit `any` — all function parameters and return types must be annotated
+- No `// @ts-ignore` or `// @ts-nocheck`
+- No `as Type` casts without a comment explaining why it's safe
+- Strict mode always on (`tsconfig.json` must have `"strict": true`)
+- No throwing — return `Result<T, E>` using a discriminated union
+- **Regularly run the linter** — Fix lint errors IMMEDIATELY
+- **Decouple providers from the VSCODE SDK** — No vscode sdk use within the providers
+- **Ignoring lints = illegal** — Fix violations immediately
 
 ### CSS
-- **Minimize duplication** - fewer classes is better
-- **Don't include section in class name** - name them after what they are - not the section they sit in
 
-## Testing
+- **Minimize duplication** — fewer classes is better
+- **Don't include section in class name** — name them after what they are - not the section they sit in
 
-⚠️ NEVER KILL VSCODE PROCESSES
+## Testing Rules
 
-#### Rules
-- **Prefer e2e tests over unit tests** - only unit tests for isolating bugs
-- Separate e2e tests from unit tests by file. They should not be in the same file together.
+- **Never delete a failing test.** Fix the code or fix the test expectation — never delete.
+- **Never skip a test** without a ticket number and expiry date in the skip reason.
+- **Assertions must be specific.** `assert.ok(true)` without a condition is illegal.
+- **No try/catch in tests** that swallows the exception and asserts success.
+- **Tests must be deterministic.** No sleep(), no relying on timing, no random state.
+- **E2E tests: black-box only.** Only interact via VS Code commands or UI. Never call provider methods directly.
+- NEVER KILL VSCODE PROCESSES
+- Separate e2e tests from unit tests by file
 - Tests must prove USER INTERACTIONS work
 - E2E tests should have multiple user interactions each and loads of assertions
 - Prefer adding assertions to existing tests rather than adding new tests
 - Test files in `src/test/suite/*.test.ts`
 - Run tests: `npm test`
-- NEVER remove assertions
-- FAILING TEST = ✅ OK. TEST THAT DOESN'T ENFORCE BEHAVIOR = ⛔️ ILLEGAL
+- FAILING TEST = OK. TEST THAT DOESN'T ENFORCE BEHAVIOR = ILLEGAL
 - Unit test = No VSCODE instance needed = isolation only test
 
 ### Automated (E2E) Testing
 
 **AUTOMATED TESTING IS BLACK BOX TESTING ONLY**
-Only test the UI **THROUGH the UI**. Do not run command etc. to coerce the state. You are testing the UI, not the code.
+Only test the UI **THROUGH the UI**. Do not run commands etc. to coerce the state.
 
 - Tests run in actual VS Code window via `@vscode/test-electron`
-- Automated tests must not modify internal state or call functions that do. They must only use the extension through the UI. 
- * - ❌ Calling internal methods like provider.updateTasks()
- * - ❌ Calling provider.refresh() directly
- * - ❌ Manipulating internal state directly
- * - ❌ Using any method not exposed via VS Code commands
- * - ❌ Using commands that should just happen as part of normal use. e.g.: `await vscode.commands.executeCommand('commandtree.refresh');`
- * - ❌ `executeCommand('commandtree.addToQuick', item)` - TAP the item via the DOM!!!
+- Automated tests must not modify internal state or call functions that do:
+  - No calling internal methods like provider.updateTasks()
+  - No calling provider.refresh() directly
+  - No manipulating internal state directly
+  - No using any method not exposed via VS Code commands
+  - No using commands that should just happen as part of normal use (e.g., commandtree.refresh)
 
 ### Test First Process
 - Write test that fails because of bug/missing feature
 - Run tests to verify that test fails because of this reason
 - Adjust test and repeat until you see failure for the reason above
 - Add missing feature or fix bug
-- Run tests to verify test passes.
+- Run tests to verify test passes
 - Repeat and fix until test passes WITHOUT changing the test
 
-**Every test MUST:**
-1. Assert on the ACTUAL OBSERVABLE BEHAVIOR (UI state, view contents, return values)
-2. Fail if the feature is broken
-3. Test the full flow, not just side effects like config files
-
-### ⛔️ FAKE TESTS ARE ILLEGAL
-
-**A "fake test" is any test that passes without actually verifying behavior. These are STRICTLY FORBIDDEN:**
-
-```typescript
-// ❌ ILLEGAL - asserts true unconditionally
-assert.ok(true, 'Should work');
-
-// ❌ ILLEGAL - no assertion on actual behavior
-try { await doSomething(); } catch { }
-assert.ok(true, 'Did not crash');
-
-// ❌ ILLEGAL - only checks config file, not actual UI/view behavior
-writeConfig({ quick: ['task1'] });
-const config = readConfig();
-assert.ok(config.quick.includes('task1')); // This doesn't test the FEATURE
-
-// ❌ ILLEGAL - empty catch with success assertion
-try { await command(); } catch { /* swallow */ }
-assert.ok(true, 'Command ran');
+### Fake Tests Are Illegal
+
+A "fake test" is any test that passes without actually verifying behavior:
+- `assert.ok(true, 'Should work')` — asserts true unconditionally
+- `try { await doSomething(); } catch { } assert.ok(true)` — no assertion on actual behavior
+- Only checking config file, not actual UI/view behavior
+- Empty catch with success assertion

 CommandTree recursively scans the workspace for runnable commands grouped by type. Discovery respects exclude patterns configured in settings. It does this in the background on low priority.
 
+## Parsing Strategy
+
+**[DISC-PARSE-STRATEGY]**
+
+Discovery modules MUST follow this hierarchy for parsing file formats:
+
+1. **VS Code built-in APIs** — Use when VS Code already parses the format natively. These are 100% reliable, handle edge cases (JSONC comments, variable substitution, input prompts), and produce zero maintenance burden. Examples:
+   - `vscode.tasks.fetchTasks()` for tasks.json
+   - `vscode.workspace.getConfiguration("launch")` for launch.json
+   - `JSON.parse()` for standard JSON files (npm, composer, deno)
+
+2. **No parsing** — If the format is simple enough that line-by-line text scanning works (shell comments, Python shebangs, Makefile targets), use that directly. No AST, no state machine.
+
+3. **Never** — Do NOT write ad-hoc parsers for structured formats (YAML, XML, TOML). If VS Code doesn't provide a built-in API and a proper parser library is needed, add one as a dependency.
+
+**Rationale**: Ad-hoc parsing of structured formats creates exponential branch complexity, is impossible to fully test, and silently breaks on valid input the author didn't anticipate. VS Code's built-in parsers are maintained by Microsoft, handle all edge cases, and cost zero lines of code.

 - **DO NOT use git commands.** No `git add`, `git commit`, `git push`, `git checkout`, `git merge`, `git rebase`, or any other git command. CI and GitHub Actions handle git.
 - **ZERO DUPLICATION.** Before writing any code, search the codebase for existing implementations. Move code, don't copy it.
-- **NO THROWING EXCEPTIONS.** Return `Result<T,E>` or the language equivalent. Exceptions are only for unrecoverable bugs (panic-level).
-- **NO REGEX on structured data.** Never parse JSON, YAML, TOML, code, or any structured format with regex. Use proper parsers, AST tools, or library functions. If text matching is absolutely necessary, prefer Regex.
+- **NO THROWING EXCEPTIONS.** Return `Result<T,E>` using a discriminated union. Exceptions are only for unrecoverable bugs (panic-level).
+- **NO REGEX on structured data.** Never parse JSON, YAML, TOML, code, or any structured format with regex. Use proper parsers, AST tools, or library functions.
 - **NO PLACEHOLDERS.** If something isn't implemented, leave a loud compilation error with TODO. Never write code that silently does nothing.
 - **Functions < 20 lines.** Refactor aggressively. If a function exceeds 20 lines, split it.
 - **Files < 450 lines.** If a file exceeds 450 lines, extract modules.
+- **No suppressing linter warnings.** Fix the code, not the linter. Fix lint errors IMMEDIATELY.
+- **CENTRALIZE global state** in one type/file.
+- **TypeScript strict mode** — No `any`, no implicit types, all lints set to error. `tsconfig.json` must have `"strict": true`.
+- No `!` (non-null assertion) — use optional chaining or explicit guards.
+- No implicit `any` — all function parameters and return types must be annotated.
+- No `// @ts-ignore` or `// @ts-nocheck`.

+## Principles

 - **100% test coverage is the goal.** Never delete or skip tests. Never remove assertions.
 - **Prefer E2E/integration tests.** Unit tests are acceptable only for isolating problems.
-- **No suppressing linter warnings.** Fix the code, not the linter.
 - **Pure functions** over statements. Prefer const and immutable patterns.

+## Lock Recovery
+
+**DB-LOCK-RECOVERY**
+
+SQLite databases can become locked by stale processes, crashed extensions, or multiple VS Code windows. When this happens, the extension MUST recover automatically.
+
+### Behavior
+
+1. On `initDb`, if the database open or schema init fails with a lock error ("locked" or "SQLITE_BUSY"):
+   - Retry every 1 second for up to 10 seconds
+   - If retries are exhausted, forcefully remove all lock artifacts and retry once more
+2. Lock artifacts to remove:
+   - `.lock` directory (SQLite directory-based locking)
+   - `-journal` file (rollback journal)
+   - `-wal` file (write-ahead log)
+   - `-shm` file (shared memory)
+3. `initDb` returns `Result<DbHandle, string>` — never throws
+4. `getDb` returns `Result<DbHandle, string>` — never throws
+5. All callers handle the error variant gracefully (log warning, degrade to empty state)
+
+### Test Coverage
+- [dbLockRecovery.unit.test.ts](../src/test/unit/dbLockRecovery.unit.test.ts): "removes .lock directory", "removes -journal file", "removes -wal file", "removes -shm file", "removes all lock artifacts at once", "succeeds when no lock artifacts exist", "succeeds on clean workspace", "returns same handle on second call", "recovers after stale lock files"

Subject: [PATCH 23/25] Remove unused fixture files that broke markdown folder
 grouping

The extra docs/api-reference.md and docs/empty.md fixture files caused
the docs/ directory to have 3 markdown files, triggering folder node
wrapping in the tree view. This made guide.md unreachable by the
markdown E2E tests which only check immediate category children.

-This is a long description that exceeds the maximum character limit for markdown descriptions which should trigger the truncation branch in the markdown parser. It needs to be over one hundred and fifty characters long to actually trigger the truncation logic so here is some additional padding text to make it sufficiently long.
