# Windows Notifications CLI and Pester Tests

Port the full `--notifications` CLI surface (template get/set/reset, on/off toggle, popups alias, status --verbose) to Windows `install.ps1` and add comprehensive Pester tests. The template resolution engine is already shipped (card kr62ia, commit 4856b0f) — this card covers the CLI and test parity.

### Initial Design Thoughts & Requirements

* Follow `--trainer` subcommand pattern exactly: outer regex match on `--notifications`, inner switch on `$Arg1` for template/on/off/help
* Template CLI uses JSON serialization pattern (not regex) for config writes — nested `notification_templates` object
* `--popups` alias: separate regex match that routes to same handler
* `--status --verbose`: extend existing `--status` handler when `$Arg1 -eq "--verbose"`
* Output format matches Unix exactly (see design doc Interface Design section)
* All PS 5.1 compatible — no PS 7+ features
* Pester tests follow `trainer-windows.Tests.ps1` pattern — `New-TestInstall` with config overrides, mock `win-notify.ps1`

### Acceptance Criteria

- [x] `peon --notifications template` shows "no notification templates configured (using defaults)" when none set
- [x] `peon --notifications template stop '{project}: {summary}'` writes to `notification_templates.stop` in config.json

- [x] `peon --notifications template bogus '{project}'` exits with code 1 and error message
- [x] `peon --notifications template --reset` removes `notification_templates` from config
- [x] `peon --notifications on` sets `desktop_notifications = true` in config
- [x] `peon --notifications off` sets `desktop_notifications = false` in config
- [x] `peon --popups off` behaves identically to `peon --notifications off`
- [x] `peon --status --verbose` shows desktop notification state with clarifying text
- [x] `peon --status --verbose` shows "sounds still play" when notifications off
- [x] `peon --status --verbose` shows mobile notification state when configured

### Implementation Notes

**Test Strategy:**
Follow `trainer-windows.Tests.ps1` pattern. `New-TestInstall` creates isolated temp dir with mock config, state, manifests, and stub `win-notify.ps1` that logs parameters. `Invoke-PeonCli` invokes `peon.ps1` with `-Command` flag. Assert config changes and CLI output.

**Pester test scenarios (19 total):**

Template CLI (13 — mirrors Unix BATS):
1. `--notifications template` shows no templates by default
2. `--notifications template stop '{project}: {summary}'` sets config
3. `--notifications template stop` shows current value
4. `--notifications template bogus '{project}'` rejects invalid key (exit 1)
5. `--notifications template --reset` clears all templates
6. Stop event with `{summary}` template renders transcript_summary
7. Stop event without transcript_summary renders empty summary
8. PermissionRequest with `{tool_name}` template renders tool name
9. No template configured falls back to project name
10. Unknown `{nonexistent}` variable renders as empty string
11. `--status` shows templates when configured
12. Template with all 5 variables renders correctly
13. Multiple templates, each renders for its event type

Notifications/verbose CLI (6):
14. `--notifications off` sets `desktop_notifications = false`
15. `--notifications on` sets `desktop_notifications = true`
16. `--popups off` behaves identically to `--notifications off`
17. `--status --verbose` shows desktop notification state
18. `--status --verbose` shows "sounds still play" when notifications off
19. `--help` includes notifications commands

**Key Implementation Decisions:**
- JSON serialization for config writes (not regex) — matches trainer pattern for nested objects
- `--notifications` switch case handles: `template`, `on`, `off`, `help` sub-verbs
- Template CLI valid keys enforced: stop, permission, error, idle, question
- Output format matches Unix exactly per design doc

## Executor Work Summary

**Commit:** `5ca8985` on branch `worktree-agent-a94156ba`

**Changes to `install.ps1`:**

1. **`--notifications` CLI handler** (new switch case `^--(notifications|popups)$`):
   - `on`/`off` subcommands: toggle `desktop_notifications` in config via JSON serialization
   - `template` subcommand: get/set/reset notification templates with 5 valid keys (stop, permission, error, idle, question)
   - `--popups` alias routes to same handler via regex alternation
   - `help` default shows usage with template keys and variables

2. **`--status --verbose` extension**: When `$Arg1 -eq \"--verbose\"`, shows:
   - Desktop notification state (on / off with \"sounds still play\" clarification)
   - Mobile notification state when configured
   - Configured notification templates

3. **`--help` text**: Added Notifications section with `--notifications` and `--popups` commands

4. **Template resolution engine** (hook mode, after event switch, before notification dispatch):
   - Maps CESP categories to template keys: task.complete->stop, task.error->error, plus event-specific mappings for permission, idle, question
   - Extracts `$event.transcript_summary` (truncated to 120 chars) and `$event.tool_name`
   - Uses `.Replace()` for named variable substitution (PS 5.1 compatible, no scriptblock regex)
   - Unknown `{variables}` cleaned via character-by-character word detection (avoids PS 5.1 regex tokenizer issues in here-strings)

5. **Bug fixes** (pre-existing issues discovered during testing):
   - Fixed `$parentPid` null on PS 5.1 (`Get-Process .Parent` is PS 6+ only; `.Parent.Id` on null returns null silently, bypassing catch block)
   - Fixed `Start-Process -ArgumentList` splitting arguments containing spaces by quoting `-body` and `-title` values

**New file: `tests/win-notification-templates.Tests.ps1`:**
- 20 Pester tests (1 syntax validation + 13 template CLI/rendering + 6 notifications CLI)
- Follows `trainer-windows.Tests.ps1` patterns: `New-TestInstall`, `Invoke-PeonCli`, `Invoke-PeonHook`, `Get-TestConfig`
- Hook-mode tests use a notify stub that logs BODY/TITLE to `.notify-log.txt` for assertion

**Test results:**
- 20/20 notification template tests pass
- 28/28 trainer tests pass (no regression)
- 360/360 adapter tests pass (no regression)
- 0 peon.ps1 parse errors (was 0 on main, still 0)

**Deferred:**
- CI green on Windows runner (can only verify post-merge)
- Code review, deployment items (for reviewer phase)
- README_zh.md translation (card scope mentions it in Phase 2 definition of done; this is a documentation task for the sprint close-out)")


## BLOCKED
Review rejection: 2 Pester tests fail on CI due to Start-Process race condition (B1), and template resolution is inlined instead of extracted as a named function per design doc (B2). See M2CLOSE-ot0edu-reviewer-1.md for details.


## Review Log

Review 1 verdict: **REJECTION** (2 blockers, 0 follow-up items)
- Review report: `.gitban/agents/reviewer/inbox/M2CLOSE-ot0edu-reviewer-1.md`
- Executor instructions: `.gitban/agents/executor/inbox/M2CLOSE-ot0edu-executor-1.md`
- B1: Replace fixed `Start-Sleep` with polling loop in all 8 hook-mode Pester tests to fix CI race condition
- B2: Extract `Resolve-NotificationTemplate` as named function per design doc instead of inlining

## Executor Work Summary (Review Cycle 2)

**Commit:** `7011e78` on branch `worktree-agent-af611716`

**B1 fix — Pester race condition (tests/win-notification-templates.Tests.ps1):**
- Replaced all 8 instances of `Start-Sleep -Milliseconds 500` with a polling loop
- Loop checks for `.notify-log.txt` every 100ms with a 5-second deadline
- Fast machines exit in ~200ms; slow CI runners get up to 5 seconds
- Eliminates non-deterministic test failures from async `Start-Process` notification dispatch

**B2 fix — Extract `Resolve-NotificationTemplate` function (install.ps1):**
- Extracted the inlined template resolution block (lines 1872-1937) into a named `Resolve-NotificationTemplate` function
- Function placed alongside other helper functions (after `Read-StateWithRetry`, before CLI commands)
- Uses `.Replace()` loop for known variables (PS 5.1 compatible) + `[regex]::Replace($rendered, '\{(\w+)\}', '')` for unknown variable cleanup
- Replaced the 20-line character-by-character loop with the single-line regex call per reviewer guidance
- Hook flow now calls the function with all required parameters, making the resolution logic independently testable
- Design doc specifies `-replace` with scriptblock, but `.Replace()` + `[regex]::Replace` is used because the function lives inside a `@'...'@` single-quoted here-string where scriptblock syntax is preserved but variable expansion is not — `.Replace()` avoids any ambiguity

**Test results (all green):**
- 20/20 notification template tests pass
- 28/28 trainer tests pass (no regression)
- 360/360 adapter tests pass (no regression)

Review 2 verdict: **APPROVAL** (0 blockers, 0 follow-up items)
- Review report: `.gitban/agents/reviewer/inbox/M2CLOSE-ot0edu-reviewer-2.md`
- Executor instructions: `.gitban/agents/executor/inbox/M2CLOSE-ot0edu-executor-2.md`
- Both blockers from review 1 resolved: Pester polling loop fix (B1) and Resolve-NotificationTemplate extraction (B2)
- Close-out item: verify CI green on Windows runner post-merge
