# Tier 2 Autonomous Sandbox Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Add an unattended Tier 2 execution mode in a sibling clone (`C:\projects\manual_slop_tier2\`) with a 3-layer enforcement stack (OpenCode permissions + Windows restricted token + git hooks), a bounded autonomous run with a failcount threshold, and an opt-in test suite.

**Architecture:** Bootstrap creates the sibling clone + installs the agent profile / slash command / git hooks templates. A PowerShell wrapper acquires a Windows restricted token and launches OpenCode under that token. The Tier 2 slash command fetches the spec, creates a feature branch, runs the plan, monitors failcount, and writes a markdown failure report on give-up. Default `uv run pytest` stays app-focused; sandbox tests are env-var-gated.

**Tech Stack:** Python 3.11+ (failcount + report + CLI), PowerShell 7+ (wrapper + bootstrap), OpenCode permission system, Windows restricted tokens + ACLs, Git 2.23+ (uses `git switch`, not `git checkout`), pytest (with `pytest.mark.skipif` opt-in pattern).

**Spec:** `conductor/tracks/tier2_autonomous_sandbox_20260616/spec.md`

**Scope:** 7 new files in main repo (1 Python module, 1 Python CLI, 2 PowerShell scripts, 1 markdown slash command, 1 markdown agent template, 1 JSON config fragment, 2 git hook templates, 1 user guide) + 4 new test files + 1 sibling clone at `C:\projects\manual_slop_tier2\` created by the bootstrap.

**Files NOT modified (DO NOT re-implement):**
- `opencode.json` (main repo) — stays as Tier 1 control plane
- `.opencode/agents/tier1-orchestrator.md`, `tier2-tech-lead.md`, `tier3-worker.md`, `tier4-qa.md`
- Any `src/*.py` file
- Any existing test file

**Modified files:**
- `pyproject.toml` — add `tier2_sandbox` and `tier2_smoke` markers (Phase 8)

### Task 1.15: Implement `load_state` and `save_state` with atomic write

- [ ] **Step 1: Replace the stubs**

Replace:
```python
def load_state(track_name: str) -> FailcountState: ...
def save_state(track_name: str, state: FailcountState) -> None: ...
```

With:
```python
def _state_dir(track_name: str) -> Path:
    """Compute the state directory for a track under the app-data temp dir."""
    base = os.environ.get(
        "TIER2_STATE_DIR",
        r"C:\Users\Ed\AppData\Local\manual_slop\tier2",
    )
    return Path(base) / track_name


def load_state(track_name: str) -> FailcountState:
    """Load state from disk, or return a fresh state if no file exists."""
    path = _state_dir(track_name) / "state.json"
    if not path.exists():
        return FailcountState()
    import json
    with path.open("r", encoding="utf-8") as f:
        return from_dict(json.load(f))


def save_state(track_name: str, state: FailcountState) -> None:
    """Atomically write state to disk. Crash-safe via temp file + replace."""
    import json
    d = _state_dir(track_name)
    d.mkdir(parents=True, exist_ok=True)
    target = d / "state.json"
    tmp = d / "state.json.tmp"
    with tmp.open("w", encoding="utf-8") as f:
        json.dump(to_dict(state), f, indent=2)
    os.replace(tmp, target)
```

- [ ] **Step 2: Run all failcount tests to verify nothing broke**

Run: `uv run pytest tests/test_failcount.py -v`
Expected: all pass

- [ ] **Step 3: Commit**

```bash
git add scripts/tier2/failcount.py
git commit -m "feat(failcount): implement load_state and save_state with atomic write"
```

### Task 1.16: Verify 100% coverage on failcount.py

- [ ] **Step 1: Run coverage**

Run: `uv run pytest tests/test_failcount.py --cov=scripts.tier2.failcount --cov-report=term-missing -v`
Expected: 100% line + branch coverage

- [ ] **Step 2: Conductor - User Manual Verification (Phase 1)**

Verify: all 13 failcount tests pass, 100% coverage on `scripts/tier2/failcount.py`.

---

## Phase 2: Failure Report Writer

**Focus:** Pure logic (mostly), takes a state + a list of task results and writes a markdown report. Test the report shape.

**Files:**
- Create: `scripts/tier2/write_report.py`
- Create: `tests/test_tier2_report_writer.py` (opt-in via `TIER2_SANDBOX_TESTS=1`)

### Task 2.1: Write `test_report_path_is_correct` (RED)

- [ ] **Step 1: Create the test file**

```python
# tests/test_tier2_report_writer.py
import os

pytestmark = pytest.mark.skipif(
    not os.environ.get("TIER2_SANDBOX_TESTS"),
    reason="opt-in: report writer test off by default; set TIER2_SANDBOX_TESTS=1",
)

    monkeypatch.setenv("TIER2_FAILURES_DIR", str(tmp_path / "failures"))
    path = compute_report_path("my_track", datetime(2026, 6, 16, 12, 0, 0, tzinfo=timezone.utc))
    assert path.parent == tmp_path / "failures"
    assert path.name.startswith("my_track_")
    assert path.name.endswith(".md")

    path = compute_stopped_flag_path("my_track")
    assert path.parent == tmp_path / "failures"
    assert path.name == "my_track.STOPPED"
```

- [ ] **Step 2: Run test to verify it fails**

Run: `TIER2_SANDBOX_TESTS=1 uv run pytest tests/test_tier2_report_writer.py -v`
Expected: ImportError (module does not exist)

- [ ] **Step 3: Commit (red)**

```bash
git add tests/test_tier2_report_writer.py
git commit -m "test(report): add report path tests (red, opt-in)"
```

### Task 2.2: Implement `compute_report_path`, `compute_stopped_flag_path`, `TaskResult` (GREEN)

- [ ] **Step 1: Create `write_report.py` with the path helpers + dataclass**

```python

## Phase 3: Slash Command + Agent Profile + Spec Test

**Focus:** The user-facing entry points. Templates the bootstrap will copy to the Tier 2 clone. A spec test verifies the markdown contract.

**Files:**
- Create: `conductor/tier2/commands/tier-2-auto-execute.md`
- Create: `conductor/tier2/agents/tier2-autonomous.md`
- Create: `conductor/tier2/opencode.json.fragment`
- Create: `tests/test_tier2_slash_command_spec.py`

### Task 3.1: Create the `tier-2-auto-execute.md` slash command template

- [ ] **Step 1: Write the slash command**

```markdown
<!-- conductor/tier2/commands/tier-2-auto-execute.md -->
---
description: Autonomously execute a conductor track in the Tier 2 sandbox
agent: tier2-autonomous
---

# /tier-2-auto-execute

Run a track autonomously in the Tier 2 sandboxed mode. No `permission: ask` prompts.

## Arguments
$ARGUMENTS - Track name (required). Examples: `result_migration_review_pass`, `data_structure_strengthening_20260606`.
Optional flags: `--resume` (continue from last completed task), `--toast` (Windows toast on give-up).

## Pre-flight

1. **Verify sandbox is active.** This slash command must be invoked from a sandboxed OpenCode session. If `manual-slop_get_ui_performance` returns an error or the run_tier2_sandboxed.ps1 wrapper is not in the parent process, refuse to start.
2. **Load the track spec.** Read `conductor/tracks/<track-name>/spec.md` and `plan.md` from the current branch. If the track does not exist, abort.
3. **Check for a previous run.** If `<app-data>/tier2/<track-name>/state.json` exists AND `--resume` is NOT set, abort with: "Previous run found for this track. Use `--resume` to continue, or delete the state file to start fresh."

## Protocol

1. `git fetch origin main`
2. `git switch -c tier2/<track-name> origin/main` (NOT `git checkout` - it is banned)
3. Initialize failcount state at `<app-data>/tier2/<track-name>/state.json` (use `load_state` or fresh state)
4. For each task in `plan.md`:
   a. Red: delegate test creation to @tier3-worker
   b. Run tests; if pass unexpectedly, call `record_red_failure` and check `should_give_up`
   c. Green: delegate implementation to @tier3-worker
   d. Run tests; if fail, call `record_green_failure` and check `should_give_up`
   e. On green: `record_commit` and `record_green_success` (resets counters)
   f. Commit per task with `git add . && git commit -m "..."` and attach git note
   g. Update `plan.md` with commit SHA
5. After all tasks complete, print success summary.
6. On give-up: call `write_failure_report` from `scripts.tier2.write_report`, print "TRACK ABORTED, see report at <path>".

## Hard Bans (enforced by 3 layers)

- `git restore*` (any form) — denied
- `git push*` (any push) — denied
- `git checkout*` (any form) — denied; use `git switch` instead
- `git reset*` (any form) — denied

Filesystem access is restricted to the Tier 2 clone + `<app-data>/manual_slop/tier2/`. The Windows restricted token blocks reads/writes outside these paths at the OS level.
```

- [ ] **Step 2: Verify the file is valid markdown frontmatter**

Run: `uv run python -c "import re; content = open('conductor/tier2/commands/tier-2-auto-execute.md').read(); m = re.match(r'---\n(.*?)\n---\n', content, re.DOTALL); assert m; print('frontmatter OK')"`
Expected: `frontmatter OK`

- [ ] **Step 3: Commit**

```bash
git add conductor/tier2/commands/tier-2-auto-execute.md
git commit -m "feat(tier2): create tier-2-auto-execute slash command template"
```

### Task 3.2: Create the `tier2-autonomous.md` agent template

- [ ] **Step 1: Write the agent prompt**

```markdown
<!-- conductor/tier2/agents/tier2-autonomous.md -->
---
description: Tier 2 Tech Lead in autonomous mode (no permission: ask, sandbox-enforced)
mode: primary
model: minimax-coding-plan/MiniMax-M3
temperature: 0.4
permission:
  edit: allow
  read:
    "*": deny
    "C:\\projects\\manual_slop_tier2\\**": allow
    "C:\\Users\\Ed\\AppData\\Local\\manual_slop\\tier2\\**": allow
    "C:\\Users\\Ed\\AppData\\Local\\manual_slop\\tier2_failures\\**": allow
  write:
    "*": deny
    "C:\\projects\\manual_slop_tier2\\**": allow
    "C:\\Users\\Ed\\AppData\\Local\\manual_slop\\tier2\\**": allow
    "C:\\Users\\Ed\\AppData\\Local\\manual_slop\\tier2_failures\\**": allow
  bash:
    "*": allow
    "git push*": deny
    "git checkout*": deny
    "git restore*": deny
    "git reset*": deny
---

STRICT SYSTEM DIRECTIVE: You are a Tier 2 Tech Lead in AUTONOMOUS mode.

You are running inside a Windows restricted token. The OpenCode permission system, the Windows ACL subsystem, and the git hooks in the clone are all enforcing the hard-ban list. A bypass of one layer is caught by another.

## Hard Bans (cannot run, enforced at 3 layers)

- `git push*` (any push) - the user pushes the branch after review
- `git checkout*` (any form) - use `git switch -c` for new branches, `git switch` to switch
- `git restore*` (any form) - do not restore files
- `git reset*` (any form) - do not reset state
- File access outside the Tier 2 clone + `C:\Users\Ed\AppData\Local\manual_slop\tier2\` - the OS blocks it

## Failcount Contract

After every task commit, you MUST check `should_give_up` from `scripts.tier2.failcount`. The state is persisted at `<app-data>/tier2/<track>/state.json`. The thresholds are:
- 3 consecutive red-phase failures
- 3 consecutive green-phase failures
- 30 minutes with no progress (no commit, no green test)

If `should_give_up` returns True, IMMEDIATELY stop. Do not attempt another fix. Call `write_failure_report` from `scripts.tier2.write_report` and print the report path.

## TDD Protocol

Same as the interactive Tier 2: Red (write failing test, run, confirm fail) -> Green (implement, run, confirm pass) -> Refactor (optional) -> commit per task.

## Pre-Delegation Checkpoint

Before each Tier 3 worker delegation, run `git add .` to stage prior work. This is a safety net: if the worker fails or incorrectly runs `git restore`, your prior iterations are not lost.

## Per-Task Commit Protocol

After each task:
1. `git add <specific files>` (not `git add .` for individual commits)
2. `git commit -m "<type>(<scope>): <description>"`
3. Get the commit hash: `git log -1 --format="%H"`
4. Attach git note: `git notes add -m "Task: ..." <hash>`
5. Update `plan.md`: change `[ ]` to `[x] <sha>` for the task
6. Commit the plan update: `git add plan.md && git commit -m "conductor(plan): Mark task complete"`

## Limitations

- You do NOT push the branch. The user fetches it back to main and reviews with Tier 1 (interactive).
- You do NOT merge to main. The user decides.
- You do NOT run the Manual Slop GUI. The MCP server runs under the same restricted token but the GUI itself is not part of the sandbox.
```

- [ ] **Step 2: Verify frontmatter is valid**

Run: `uv run python -c "import re; content = open('conductor/tier2/agents/tier2-autonomous.md').read(); m = re.match(r'---\n(.*?)\n---\n', content, re.DOTALL); assert m; print('frontmatter OK')"`
Expected: `frontmatter OK`

- [ ] **Step 3: Commit**

```bash
git add conductor/tier2/agents/tier2-autonomous.md
git commit -m "feat(tier2): create tier2-autonomous agent profile template"
```

### Task 3.3: Create the `opencode.json.fragment` config template

- [ ] **Step 1: Write the config fragment**

```json
{
  "$schema": "https://opencode.ai/config.json",
  "default_agent": "tier2-autonomous",
  "agent": {
    "tier2-autonomous": {
      "model": "minimax-coding-plan/MiniMax-M3",

          "git reset*": "deny"
        }
      }
    }
  }
}
```

- [ ] **Step 2: Verify the JSON is valid**

Run: `uv run python -c "import json; print(json.load(open('conductor/tier2/opencode.json.fragment')))"`
Expected: dict printed (no error)

- [ ] **Step 3: Commit**

```bash
git add conductor/tier2/opencode.json.fragment
git commit -m "feat(tier2): create opencode.json.fragment agent config"
```

### Task 3.4: Write `test_tier2_slash_command_spec.py`

- [ ] **Step 2: Run the test to verify it passes**

Run: `uv run pytest tests/test_tier2_slash_command_spec.py -v`
Expected: 11 passed

- [ ] **Step 3: Commit**

```bash
git add tests/test_tier2_slash_command_spec.py
git commit -m "test(tier2): add slash command spec test"
```

### Task 3.5: Conductor - User Manual Verification (Phase 3)

Verify: all 11 slash command spec tests pass, all 3 template files are present and well-formed.

---

## Phase 4: CLI Entry Point (`run_track.py`)

**Focus:** The slash command's protocol duplicated as a CLI so the smoke e2e test can run without an OpenCode session. The slash command itself becomes a thin wrapper that calls this CLI.

**Files:**
- Create: `scripts/tier2/run_track.py`

### Task 4.1: Create `run_track.py` skeleton with argparse

- [ ] **Step 1: Write the CLI skeleton**

```python
# scripts/tier2/run_track.py
"""CLI entry point for the Tier 2 autonomous track execution.

Duplicates the /tier-2-auto-execute slash command's protocol so the
smoke e2e test can run without an OpenCode session. The slash command

### Task 4.2: Wire in git fetch + branch creation

- [ ] **Step 1: Replace `main()` with the wired-in version**

Replace `main()` with:
```python
def main() -> int:
    args = parse_args()
    repo_path = Path(args.repo_path)
    branch_name = f"tier2/{args.track_name}"

Run against the Tier 2 clone (after bootstrap in Phase 5):
```bash
uv run python scripts/tier2/run_track.py test_track --repo-path C:/projects/manual_slop_tier2
```
Expected: prints the 3 status lines + `track initialized; ready for plan execution`, exit 0, branch `tier2/test_track` exists in the clone.

- [ ] **Step 3: Commit**

```bash
git add scripts/tier2/run_track.py
git commit -m "feat(tier2): wire in git fetch + branch creation in run_track"
```

### Task 4.3: Conductor - User Manual Verification (Phase 4)

Verify: the CLI runs against a Tier 2 clone (or skip if clone doesn't exist yet), exits 0, creates the feature branch via `git switch -c`.

## Phase 5: PowerShell Bootstrap (`setup_tier2_clone.ps1`)

**Focus:** One-time setup. Idempotent. `-WhatIf` support. Creates the sibling clone, copies templates, installs hooks, sets up app-data dir, creates desktop shortcut.

.SYNOPSIS
  One-time bootstrap for the Tier 2 autonomous sandbox.

  templates, installs the git hooks, creates the app-data temp dir with
  restricted ACLs, and creates a "Tier 2 (Sandboxed)" desktop shortcut.

### Task 5.2: Conductor - User Manual Verification (Phase 5)

User runs:
```powershell
pwsh -File C:\projects\manual_slop\scripts\tier2\setup_tier2_clone.ps1 -WhatIf

## Phase 6: PowerShell Sandbox Launcher (`run_tier2_sandboxed.ps1`)

**Focus:** The actual sandbox enforcement. Acquires a restricted token, sets ACLs, wraps the process tree in a Job Object, launches OpenCode + MCP server.

**Files:**
- Create: `scripts/tier2/run_tier2_sandboxed.ps1`

### Task 6.2: Conductor - User Manual Verification (Phase 6)

User runs the launcher from the desktop shortcut (or directly via `pwsh -File ...`). Verify OpenCode opens in the Tier 2 clone.

---

## Phase 7: Git Hooks

**Focus:** Defense-in-depth. The OpenCode permission system is the primary enforcement; these hooks are the backup.

**Files:**
- Create: `conductor/tier2/githooks/pre-push`
- Create: `conductor/tier2/githooks/post-checkout`

### Task 7.1: Create `pre-push` hook

- [ ] **Step 1: Write the pre-push hook**

```bash
# conductor/tier2/githooks/pre-push
#!/bin/sh
# Tier 2 autonomous mode: `git push` is disabled.
# The user pushes the branch manually from the main repo after review.

echo "ERROR: Tier 2 autonomous mode: 'git push' is disabled." >&2
echo "Push the branch manually from the main repo after review." >&2
exit 1
```

- [ ] **Step 2: Commit**

```bash
git add conductor/tier2/githooks/pre-push
git commit -m "feat(tier2): add pre-push hook that refuses all pushes"
```

### Task 7.2: Create `post-checkout` hook

- [ ] **Step 1: Write the post-checkout hook**

```bash
# conductor/tier2/githooks/post-checkout
#!/bin/sh
# Tier 2 autonomous mode: detect (not prevent) any `git checkout` of tracked files.
# Layer 1 (OpenCode permission) is the primary defense; this is a logging backup.

LOG_DIR="${LOCALAPPDATA:-$HOME/.local/share}/manual_slop/tier2"
LOG_FILE="$LOG_DIR/tier2_checkout_log.txt"
mkdir -p "$LOG_DIR" 2>/dev/null || true

COMMIT=$(git rev-parse HEAD 2>/dev/null || echo "unknown")
TIMESTAMP=$(date -u +"%Y-%m-%dT%H:%M:%SZ" 2>/dev/null || date -u)
echo "[$TIMESTAMP] checkout detected: $COMMIT, files: $*" >> "$LOG_FILE" 2>/dev/null || true

git add conductor/tier2/githooks/post-checkout
git commit -m "feat(tier2): add post-checkout detection hook"
```

---

## Phase 8: Opt-in Tests (Sandbox Enforcement + Smoke E2E)

**Focus:** Verify the sandbox actually enforces the bans. Opt-in to keep the default test run app-focused.

**Files:**
- Modify: `pyproject.toml` (add markers)
- Create: `tests/test_tier2_setup_bootstrap.py`
- Create: `tests/test_tier2_sandbox_enforcement.py`
- Create: `tests/test_tier2_smoke_e2e.py`
- Create: `tests/artifacts/tier2_smoke_track/spec.md`
- Create: `tests/artifacts/tier2_smoke_track/plan.md`

### Task 8.1: Add markers to `pyproject.toml`

- [ ] **Step 1: Find the `[tool.pytest.ini_options]` section in `pyproject.toml`**

Run: `grep -n "tool.pytest.ini_options" pyproject.toml`
Expected: a line number

- [ ] **Step 2: Add the markers to the existing markers list (or create it)**

The existing `markers = [...]` list (if present) needs these added:
```toml
"tier2_sandbox: opt-in sandbox tests (set TIER2_SANDBOX_TESTS=1)",
"tier2_smoke: opt-in full e2e (set TIER2_SANDBOX_TESTS=1 TIER2_SMOKE=1)",
```

If there is no existing markers list, add the whole block.

- [ ] **Step 3: Verify pytest collects the markers**

Run: `uv run pytest --markers | grep tier2`
Expected: 2 lines (`tier2_sandbox` and `tier2_smoke`)

- [ ] **Step 4: Commit**

```bash
git add pyproject.toml
git commit -m "test(tier2): add tier2_sandbox and tier2_smoke pytest markers"
```

### Task 8.2: Create the trivial smoke track

- [ ] **Step 1: Create the smoke track spec**

```markdown
<!-- tests/artifacts/tier2_smoke_track/spec.md -->
# Smoke Track: trivial doc-file addition

## Overview
A 1-task track that just adds a single doc file. Used by the smoke e2e
test to verify the full Tier 2 pipeline (bootstrap + branch + commit).

## Goals
- Add `tests/artifacts/tier2_smoke_track/added.md` with one line of content
- Commit the file on a feature branch
- Verify the branch exists with 1 commit

## Functional Requirements
- FR1: create the file with content "smoke test ok\n"
- FR2: commit with message "test(tier2): smoke e2e track"

## Out of Scope
- Anything else.
```

- [ ] **Step 2: Create the smoke track plan**

```markdown
<!-- tests/artifacts/tier2_smoke_track/plan.md -->
# Implementation Plan: smoke track

## Phase 1: Add the file

- [ ] Task 1.1: Create `tests/artifacts/tier2_smoke_track/added.md` with content `smoke test ok\n`
- [ ] Task 1.2: Commit with message `test(tier2): smoke e2e track`
```

- [ ] **Step 3: Commit**

```bash
git add tests/artifacts/tier2_smoke_track/
git commit -m "test(tier2): add trivial smoke track for e2e test"
```

### Task 8.3: Create `test_tier2_setup_bootstrap.py` (opt-in)

- [ ] **Step 1: Create the test file**

```python
# tests/test_tier2_setup_bootstrap.py
"""Opt-in integration test for the setup_tier2_clone.ps1 bootstrap.

Runs the script in -WhatIf mode against a fixture workspace. The full
non-WhatIf run is a manual verification (the user runs it once and
inspects the result).

    """pwsh -WhatIf should print the steps but not actually clone."""
    fake_main = tmp_path / "fake_main"
    fake_main.mkdir()
    fake_clone = tmp_path / "fake_clone"
    # The bootstrap uses Resolve-Path on $MainRepoPath; we need a real path
    script = Path("scripts/tier2/setup_tier2_clone.ps1").resolve()
    result = subprocess.run(
        [
            "pwsh", "-NoProfile", "-File", str(script),

    assert result.returncode == 0
    assert "What if" in result.stdout or "starting bootstrap" in result.stdout
    assert not fake_clone.exists(), "-WhatIf should not have created the clone"
```

- [ ] **Step 2: Run with the opt-in gate set**

Run: `TIER2_SANDBOX_TESTS=1 uv run pytest tests/test_tier2_setup_bootstrap.py -v`
Expected: PASS

- [ ] **Step 3: Run without the gate to confirm it skips**

Run: `uv run pytest tests/test_tier2_setup_bootstrap.py -v`
Expected: SKIPPED with the opt-in reason

- [ ] **Step 4: Commit**

```bash
git add tests/test_tier2_setup_bootstrap.py
git commit -m "test(tier2): add bootstrap -WhatIf test (opt-in)"
```

### Task 8.4: Create `test_tier2_sandbox_enforcement.py` (opt-in)

- [ ] **Step 1: Create the test file**

```python
# tests/test_tier2_sandbox_enforcement.py
"""Opt-in integration test for the sandbox enforcement.

    assert "git push" in result.stderr.lower() or "disabled" in result.stderr.lower()
```

- [ ] **Step 2: Run with the opt-in gate set**

Run: `TIER2_SANDBOX_TESTS=1 uv run pytest tests/test_tier2_sandbox_enforcement.py -v`
Expected: PASS (the pre-push hook refuses the push)

- [ ] **Step 3: Commit**

```bash
git add tests/test_tier2_sandbox_enforcement.py
git commit -m "test(tier2): add sandbox enforcement test (opt-in, pre-push hook)"
```

### Task 8.5: Create `test_tier2_smoke_e2e.py` (opt-in, double gate)

- [ ] **Step 1: Create the test file**

```python

### Task 8.6: Conductor - User Manual Verification (Phase 8)

Verify:
- `uv run pytest` (no env vars) passes all default-on tests, skips all opt-in tests
- `TIER2_SANDBOX_TESTS=1 uv run pytest` runs the opt-in tests (some may pass, some may be environment-dependent)
- `TIER2_SANDBOX_TESTS=1 TIER2_SMOKE=1 uv run pytest` runs the full e2e

---

## Phase 9: User Guide + Final Verification

**Focus:** The user-facing documentation. The "Verify the sandbox" checklist.

**Files:**
- Create: `docs/guide_tier2_autonomous.md`

### Task 9.1: Create the user guide

- [ ] **Step 1: Write the guide**

```markdown
<!-- docs/guide_tier2_autonomous.md -->
# Tier 2 Autonomous Sandbox

## Why this exists

When you run Tier 2 in the main repo, every `edit` and every `bash`
call prompts you for approval (`permission: ask`). For well-regularized
tracks (TDD red/green with atomic per-task commits), this is noise.
This track adds an **autonomous mode** in a sibling clone where Tier 2
runs unattended, with a 3-layer enforcement stack to keep it contained.

## One-time bootstrap

```powershell
cd C:\projects\manual_slop
pwsh -File scripts\tier2\setup_tier2_clone.ps1 -WhatIf   # dry run first
pwsh -File scripts\tier2\setup_tier2_clone.ps1            # actual bootstrap
```

The bootstrap:
1. Clones the main repo to `C:\projects\manual_slop_tier2\`
2. Sets `origin = C:\projects\manual_slop` (local path; no remote)
3. Copies the agent, slash command, and opencode.json templates to the clone
4. Installs the git hooks (`pre-push` refuses all pushes; `post-checkout` logs checkouts)
5. Creates `C:\Users\Ed\AppData\Local\manual_slop\tier2\` with restricted ACLs
6. Creates a "Tier 2 (Sandboxed)" desktop shortcut

## Per-track invocation

1. Double-click the "Tier 2 (Sandboxed)" desktop shortcut
   (or run `pwsh -File C:\projects\manual_slop\scripts\tier2\run_tier2_sandboxed.ps1` manually)
2. In the OpenCode session, type:
   ```
   /tier-2-auto-execute <track-name>
   ```
   Examples:
   - `/tier-2-auto-execute result_migration_review_pass`
   - `/tier-2-auto-execute data_structure_strengthening_20260606 --resume`
   - `/tier-2-auto-execute rag_test_failures_20260615 --toast`
3. Tier 2 runs the track autonomously, commits per task, monitors failcount
4. On success: prints a summary
5. On give-up: writes a failure report and prints the path

## Review and merge

After Tier 2 finishes (success or give-up):
1. `cd C:\projects\manual_slop` (back to main)
2. `git fetch C:/projects/manual_slop_tier2 tier2/<track-name>`
3. Review the diff with Tier 1 (interactive)
4. On approval: `git merge --no-ff tier2/<track-name>` to main

## The 4 hard bans (enforced at 3 layers)

| Ban | Layer 1 (OpenCode) | Layer 2 (OS) | Layer 3 (git hook) |
|---|---|---|---|
| `git push*` (any push) | `permission.bash` deny rule | n/a | `pre-push` hook refuses all pushes |
| `git checkout*` (any form) | `permission.bash` deny rule | n/a | `post-checkout` hook logs the checkout |
| `git restore*` (any form) | `permission.bash` deny rule | n/a | n/a |
| `git reset*` (any form) | `permission.bash` deny rule | n/a | n/a |
| File access outside Tier 2 clone + app-data dir | `permission.read`/`write` path allowlist | Windows ACL | n/a |

## The failcount threshold

Tier 2 gives up if ANY of these hit:
- 3 consecutive red-phase failures (the test doesn't fail when it should)
- 3 consecutive green-phase failures (the implementation doesn't make the test pass)
- 30 minutes with no progress (no commit, no green test)

Override via `scripts/tier2/failcount.toml`.

## The failure report

Written to `C:\Users\Ed\AppData\Local\manual_slop\tier2_failures\<track>_<timestamp>.md` with 7 sections:
1. Header (track, branch, started, stopped, duration, give-up signal)
2. Tasks completed
3. Current task (where it stopped)
4. Last 3 failures
5. Failcount state
6. Git state (`git log tier2/<track> ^origin/main`)
7. Recommendation (heuristic-based)

A `.STOPPED` flag file is created alongside the report. The main repo
can check for it on next Tier 1 session start (an opt-in banner).

## Verify the sandbox (manual checklist)

After bootstrap, run these inside the Tier 2 sandboxed OpenCode session
to verify the bans are enforced:

- [ ] Try `git restore tests/test_failcount.py` — should print "denied"
- [ ] Try `git push origin main` — should print "denied" (or the pre-push hook fires)
- [ ] Try `git checkout -- src/foo.py` — should print "denied"
- [ ] Try `git reset --hard HEAD~1` — should print "denied"
- [ ] Try to read `C:\Users\Ed\Documents\test.txt` (from a Python subprocess) — should print "ACCESS_DENIED"

And verify allowed operations work:
- [ ] `git status` — works
- [ ] `git switch -c test-branch` — works
- [ ] Edit a file in the Tier 2 clone — works
- [ ] `git add <file> && git commit -m "test"` — works

## Troubleshooting

- **"Tier 2 (Sandboxed) shortcut doesn't work"**: check that
  `pwsh.exe` is on the PATH (`where.exe pwsh`).
- **"Permission denied" on file access inside the sandbox**: the
  Windows ACL may be too restrictive. Re-run the bootstrap
  (`setup_tier2_clone.ps1` is idempotent).
- **"Failcount state not found"**: the `<app-data>/tier2/<track>/`
  dir may be missing. The bootstrap creates it; check `$env:LOCALAPPDATA`.
- **"Pre-push hook not firing"**: check that `.git/hooks/pre-push`
  is executable. On Windows, Git Bash runs the hook; check
  `git config core.hooksPath` if you have a custom hooks dir.
- **"Tier 2 keeps giving up at 30 min"**: increase
  `no_progress_minutes` in `scripts/tier2/failcount.toml`.
```

- [ ] **Step 2: Verify the file is valid markdown (no broken links)**

Run: `uv run python -c "from pathlib import Path; p = Path('docs/guide_tier2_autonomous.md'); assert p.exists(); print(f'{len(p.read_text())} bytes')"`
Expected: a number of bytes printed

- [ ] **Step 3: Commit**

```bash
git add docs/guide_tier2_autonomous.md
git commit -m "docs(tier2): add user guide for Tier 2 autonomous sandbox"
```

### Task 9.2: Update `conductor/tracks.md` with the new track

- [ ] **Step 1: Find the appropriate section in `conductor/tracks.md`**

Read the top of `conductor/tracks.md` to find where the active tracks
list lives. Add an entry for `tier2_autonomous_sandbox_20260616`.

- [ ] **Step 2: Add the row to the active tracks table**

Add a row to the "Active Tracks (Current Queue)" table:
```markdown
| 25 | A | [Tier 2 Autonomous Sandbox](#track-tier-2-autonomous-sandbox-new-2026-06-16) | spec ✓, plan ✓, ready to start | (none — independent; **NEW 2026-06-16**; meta-tooling; eliminates the `permission: ask` bottleneck for well-regularized tracks) |
```

Then add the corresponding section heading further down:
```markdown
### Track: Tier 2 Autonomous Sandbox (NEW 2026-06-16)

[./tracks/tier2_autonomous_sandbox_20260616/](./tracks/tier2_autonomous_sandbox_20260616/)
```

- [ ] **Step 3: Commit**

```bash
git add conductor/tracks.md
git commit -m "conductor(plan): register tier2_autonomous_sandbox_20260616 in tracks.md"
```

### Task 9.3: Create `metadata.json`

- [ ] **Step 1: Write the metadata**

```json
{
  "id": "tier2_autonomous_sandbox_20260616",
  "title": "Tier 2 Autonomous Sandbox (unattended track execution with bounded blast radius)",
  "type": "feature",
  "status": "planned",
  "priority": "high",
  "created": "2026-06-16",
  "owner": "tier2-tech-lead",
  "spec": "conductor/tracks/tier2_autonomous_sandbox_20260616/spec.md",
  "plan": "conductor/tracks/tier2_autonomous_sandbox_20260616/plan.md",
  "scope": {
    "new_files": 21,
    "modified_files": 1,
    "deleted_files": 0
  },
  "depends_on": [],
  "blocks": [],
  "test_summary": {
    "default_on_tests": 24,
    "opt_in_tests_sandbox": 4,
    "opt_in_tests_smoke": 1
  },
  "verification_criteria": [
    "All failcount unit tests pass (13 tests, 100% coverage on scripts/tier2/failcount.py)",
    "Slash command spec test passes (11 contract assertions)",
    "Report writer tests pass (4 opt-in tests)",
    "Bootstrap -WhatIf runs without error",
    "Pre-push hook refuses a push attempt (sandbox enforcement test)",
    "Smoke e2e creates a feature branch via git switch -c",
    "User guide covers bootstrap, invocation, manual verification checklist",
    "Default uv run pytest stays app-focused (opt-in tests skip without env vars)"
  ]
}
```

- [ ] **Step 2: Verify the JSON is valid**

Run: `uv run python -c "import json; print(json.load(open('conductor/tracks/tier2_autonomous_sandbox_20260616/metadata.json')))"`
Expected: dict printed

- [ ] **Step 3: Commit**

```bash
git add conductor/tracks/tier2_autonomous_sandbox_20260616/metadata.json
git commit -m "conductor(plan): add metadata.json for tier2_autonomous_sandbox"
```

### Task 9.4: Final Conductor - User Manual Verification

Verify the complete track:
1. `uv run pytest` (no env vars) — all default-on tests pass, all opt-in tests skip
2. `TIER2_SANDBOX_TESTS=1 uv run pytest` — sandbox-layer tests pass
3. `TIER2_SANDBOX_TESTS=1 TIER2_SMOKE=1 uv run pytest` — full e2e passes
4. The user guide renders correctly in a markdown viewer
5. The track is registered in `conductor/tracks.md`
6. The spec + plan + metadata.json are all present in `conductor/tracks/tier2_autonomous_sandbox_20260616/`

---

## Self-Review (against the spec)

**1. Spec coverage:**

| Spec FR | Covered by |
|---|---|
| FR1.1, FR1.2, FR1.3 (bootstrap) | Phase 5 Tasks 5.1, 5.2 |
| FR2.1, FR2.2, FR2.3 (tier2-autonomous agent) | Phase 3 Tasks 3.1, 3.2, 3.3 |
| FR3.1, FR3.2, FR3.3 (sandboxed launcher) | Phase 6 Task 6.1 |
| FR4.1, FR4.2, FR4.3, FR4.4 (slash command) | Phase 3 Task 3.1 + Phase 4 Tasks 4.1, 4.2 |
| FR5.1, FR5.2, FR5.3, FR5.4 (failcount) | Phase 1 Tasks 1.3-1.15 |
| FR6.1, FR6.2, FR6.3, FR6.4 (report writer) | Phase 2 Tasks 2.1-2.4 |
| FR7.1, FR7.2, FR7.3 (git hooks) | Phase 7 Tasks 7.1, 7.2 |
| FR8.1, FR8.2 (user guide) | Phase 9 Task 9.1 |
| FR9.1 (failcount tests, default-on) | Phase 1 Tasks 1.2-1.15 |
| FR9.2 (slash command spec test, default-on) | Phase 3 Task 3.4 |
| FR9.3 (bootstrap test, opt-in) | Phase 8 Task 8.3 |
| FR9.4 (sandbox enforcement test, opt-in) | Phase 8 Task 8.4 |
| FR9.5 (report writer test, opt-in) | Phase 2 Tasks 2.1, 2.3 |
| FR9.6 (smoke e2e test, opt-in) | Phase 8 Tasks 8.2, 8.5 |

**2. Placeholder scan:** No TBD/TODO in the plan. The "TODO" comments in Task 4.2 are explicit anchors for subsequent tasks, not placeholders. All PowerShell and Python code is complete.

**3. Type consistency:** `FailcountState` is consistent across `failcount.py` and all tests. `TaskResult` is consistent across `write_report.py` and all tests. `compute_report_path` / `compute_stopped_flag_path` signatures are consistent.

**4. Spec requirements with no task:** none — all 9 sections of FRs are covered.

**Self-review verdict: plan is ready for user review.**

---

## Execution Handoff

**Plan complete and saved to `conductor/tracks/tier2_autonomous_sandbox_20260616/plan.md`.**

Two execution options:

**1. Subagent-Driven (recommended)** — I dispatch a fresh subagent per task, review between tasks, fast iteration. Best for this track because Phase 1 (15+ tests + module) benefits from focused per-task work.

**2. Inline Execution** — Execute tasks in this session using executing-plans, batch execution with checkpoints. Best if you want to watch the implementation happen in real-time.

**Which approach?**
