v2.0: state enforcement, project scoping, harness integration
CI / build (push) Has been cancelled

State Enforcement (v2.0):
- .state file as single source of truth for task phase
- Approval gates for research, decomposition, design, test_design
- status.py --transition refuses illegal phase transitions
- status.py --validate-folder detects out-of-order artifacts
- status.py --audit checks all tasks for violations
- status.py --create-task is the only valid way to create tasks
- Pre-v2.0 tasks without .state are UNTRACKED -- all commands refuse them
- New --upgrade command bootstraps .state files for existing tasks

Project Scoping:
- --project flag added to all status.py commands across 16+ files
- _find_project_dir errors instead of silently falling back to ~/.automaton/
- --scope-check marks framework files OUT_OF_SCOPE when working on a project
- Dashboard handlers use stored project_root instead of re-detecting from CWD
- Prompts reference ~/.automaton/scripts/vram_detect.py (not {project}/.automaton/)

Harness Integration:
- status.py --can-edit now supports project-level checks (no --task required)
- --can-edit --file checks file scope without --task
- --json output for machine-readable harness integration
- opencode plugin (plugins/automaton-guard/plugin.ts) intercepts edit/write
- Git pre-commit hook (scripts/git-hooks/pre-commit) blocks commits without task
- Formal integration contract (contracts/harness-integration.md)

Other:
- upgrade.sh delegates to status.py --upgrade instead of manual heuristics
- Phase prompts reference --project {project} for multi-project scoping
- 200 tests passing (14 new)

# Adversarial Bug Report: task-status-reason
## Summary
Deep-dive audit found 3 subtle issues: misleading red border on bug_find cards, redundant verdict parsing, and no status_reason propagation to subtasks.
## Bugs Found
### Bug 1: Red error border on bug_find task cards is misleading
- **Severity**: Low
- **Location**: `automaton/dashboard/html/styles.css` — `.task-card-reason` rule
- **Description**: The `.task-card-reason` CSS uses `border-left: 2px solid var(--error)` for all three states (blocked, bug_find, adv_bug_find). But `bug_find` and `adv_bug_find` are normal workflow states, not errors. A green or neutral border would be more appropriate for non-terminal states.
- **Reproduction**: Open any task in bug_find or adv_bug_find state — the reason banner shows a red border suggesting something is wrong, when it's expected behavior.
- **Suggested Fix**: Use `var(--warning)` for bug_find states and reserve `var(--error)` for blocked only.
### Bug 2: Redundant verdict parsing on every status_reason access
- **Severity**: Low
- **Location**: `automaton/dashboard/core/task.py:136-175` — `status_reason` property
- **Description**: `status_reason` calls `parse_verdict_status()` again for BLOCKED/DONE tasks, even though `determine_task_state()` already parsed the verdict to classify the state. For DONE, it doesn't re-parse (just returns "Verdict: PASS"), but for BLOCKED it re-reads the verdict content and re-parses. This is redundant but cheap given the small number of tasks.
- **Reproduction**: Every time the dashboard renders, BLOCKED tasks trigger a second verdict parse just for the display string.
- **Suggested Fix**: Cache the parsed verdict status on the Task object during `discover_tasks()`, e.g., a `_verdict_status` field that `status_reason` can reference instead of re-parsing.
### Bug 3: Subtask state not visible in detail panel reason
- **Severity**: Low
- **Location**: `automaton/dashboard/html/dashboard.js:236-241` — subtask list in detail panel
- **Description**: Subtasks in the detail panel show only a verdict pass/fail indicator. Unlike parent tasks, blocked subtasks don't display their status_reason in the list. A blocked subtask just shows "✗" next to its name with no explanation of why.
- **Suggested Fix**: For blocked subtasks, include the subtask's verdict status (FAIL/NEEDS_REVIEW) in the list item, or hover tooltip with the reason.
### Bug 4: Fallthrough status_reason never reached, masks missing states
- **Severity**: Low
- **Location**: `automaton/dashboard/core/task.py:175`
- **Description**: The fallthrough `return f"In {self.state.value} phase"` is dead code — every TaskState value is covered by explicit branches. If a new state is added (e.g., INTEGRATION_TEST), no compile-time error occurs and a vague message is shown. Contrast with Python enums which have no exhaustiveness checking.
- **Suggested Fix**: Add `# pragma: no cover` or raise/log a warning if a new state goes unhandled.

# Bug Report: task-status-reason
## Summary
Audit of status_reason implementation against SPEC.md found minor issues: a dead-code branch in the status_reason message, and a pre-existing REFEREE state that's never produced.
## Bugs Found
### Bug 1: Dead message branch in status_reason for BLOCKED state
- **Severity**: Low
- **Location**: `automaton/dashboard/core/task.py:149`
- **Description**: The message `"Verdict is empty or could not be parsed"` has two scenarios:
1. Empty verdict → reachable (content is `""`, correctly returns this message)
2. Unparseable verdict → unreachable. When `parse_verdict_status()` returns `None`, the state machine in `determine_task_state()` doesn't classify the task as BLOCKED — it falls through to earlier state checks. So a task is never both BLOCKED and "could not be parsed".
- **Suggested Fix**: Change message to `"Verdict is empty"` to accurately reflect the only reachable case.
### Bug 2: REFEREE state never produced by state machine
- **Severity**: Low
- **Location**: `automaton/dashboard/core/task.py:174` (fallback `status_reason` line), and `task.py:226-272` (determine_task_state)
- **Description**: `TaskState.REFEREE` exists in the enum and in the sort order, but `determine_task_state` never returns it. When a VERDICT.md is present but unparseable, the state machine falls through to earlier artifact checks instead of assigning REFEREE. This means the fallback status reason `"In referee phase"` is unreachable, and tasks with ambiguous verdicts silently show as earlier states (e.g., RESEARCH if only SPEC.md exists alongside an unparseable VERDICT.md).
- **Pre-existing**: This predates the task and is not introduced by the implementation, but the status_reason property exposes it because the REFEREE branch is dead code.
- **Suggested Fix**: Add `if "VERDICT.md" in artifacts: return TaskState.REFEREE, artifacts` after the terminal-state checks in `determine_task_state()`, before the state machine fallthrough.
### Bug 3: REFEREE status reason is generic
- **Severity**: Low
- **Location**: `automaton/dashboard/core/task.py:175`
- **Description**: The fallthrough line `return f"In {self.state.value} phase"` would produce generic messages like `"In blocked phase"` or `"In done phase"` for states that are handled above it. This is actually dead code for all defined states since every `TaskState` value is covered by an explicit `if` branch. If a new state is added without adding a status_reason handler, it gets a generic message rather than failing loudly.
- **Suggested Fix**: Replace the fallthrough with a clear signal: either raise an error, or explicitly list the catch to alert developers when adding states.

# Documentation Review: task-status-reason
## Summary
No DESIGN.md. Conducting ad-hoc review of code documentation for the status_reason feature.
## Documentation Completeness
- Code documentation: Adequate — `status_reason` property has a docstring. `parse_verdict_status` was already documented. No DESIGN.md or deployment docs produced (proportional to the small change set).
- User documentation: Not updated — the dashboard README (`automaton/dashboard/README.md`) doesn't mention the status reason display. The new status_reason field in the API response is also undocumented.
- API documentation: No formal API docs exist for the dashboard endpoints.
## Issues Found
### Issue 1: Dashboard README not updated for status reason display
- **Severity**: Low
- **Description**: The dashboard README at `automaton/dashboard/README.md` doesn't document that the detail panel now shows a status reason. This is a user-facing UI change without documentation.
- **Suggested Fix**: Add a note to the README under "Detail Panel" section describing the status reason.
### Issue 2: CHANGELOG entry missing bug fixes
- **Severity**: Low
- **Description**: The CHANGELOG correctly lists the status_reason feature and revoke buttons, but doesn't mention the REFEREE state fix (a consequence of Bug 2 fix from BUG_REPORT.md).
- **Suggested Fix**: Add a Fixed entry for the REFEREE state being unreachable.

# Implementation: Add Status Reason to Task Display
## Summary
Added `status_reason` property to `Task` model providing human-readable explanations for each task state, exposed it in API responses, displayed it prominently in the detail panel and on task cards. Fixed the pending review count to exclude terminal-state tasks. Replaced approve/request-changes buttons with revoke buttons when a review is already submitted.
## Changes
- `automaton/dashboard/core/task.py`: Added `status_reason` property on `Task` with explanations for all 10+ task states
- `automaton/dashboard/ui/app.py`: Added `status_reason` to `_serve_tasks()` and `_serve_task()` JSON responses; accepted `"pending"` as valid review status
- `automaton/dashboard/html/dashboard.js`: Displayed `status_reason` in detail panel and on task cards; fixed pending count to exclude done/blocked; added conditional button rendering for approved/changes_requested reviews
- `automaton/dashboard/html/styles.css`: Added `.detail-status-reason` and `.task-card-reason` styles
- `tests/test_task.py`: Added `TestStatusReason` class with 5 tests covering done, blocked, and in-progress states

# Add Status Reason to Task Display
## Goal
Show a human-readable explanation of *why* a task is in its current state, fix the pending review count to exclude terminal-state tasks, and replace approve/request-changes buttons with revoke buttons when a review is already submitted.
## Requirements
### R1. Add `status_reason` property to Task
Add a `status_reason` property on the `Task` dataclass that derives a human-readable explanation from the task's state, artifacts, and verdict status. For example:
- DONE → "Verdict: PASS"
- BLOCKED → "Verdict: FAIL — changes required before re-review"
- BUG_FIND (with IMPLEMENTATION.md) → "Implementation complete — awaiting bug finding"
- BACKLOG → "No artifacts yet — not started"
### R2. Expose `status_reason` in API responses
Include `status_reason` in the JSON response for both `/api/tasks` and `/api/task/{name}`.
### R3. Display status reason prominently
- Show `status_reason` below the status badge in the task detail panel
- Show `status_reason` on task cards for blocked/bug_find/adv_bug_find states
### R4. Fix pending review count
The pending review counter in the header currently counts all tasks without a review, including DONE tasks. Fix it to exclude terminal states (done, blocked) so only active tasks count toward pending.
### R5. Replace review buttons with revoke on submitted reviews
When a task already has an approved review, replace the approve button with "Revoke Approval". When changes are requested, replace with "Revoke Changes". Both send status="pending" to reset the review.
## Acceptance Criteria
- [ ] `status_reason` property works for all task states
- [ ] `/api/tasks` responses include `status_reason`
- [ ] Detail panel shows status reason below the status badge
- [ ] Task cards show status reason for blocked/bug_find/adv_bug_find tasks
- [ ] Pending review count excludes done/blocked tasks
- [ ] Approved tasks show "Revoke Approval" instead of "Approve"
- [ ] Backend accepts "pending" as a review status
- [ ] All tests pass
## Non-Goals
- Not changing the task state machine — revoking a review only resets the review metadata, not the task state
- Not adding buttons to change task state directly (e.g., send back to planning) — that's a larger feature
