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

Implementation: Status Script

Changes Made

1. Core script: scripts/status.py (980 lines)

Full implementation of all commands specified in the SPEC:

  • --task {name} — Shows phase, allowed/forbidden actions, next artifact, next phase, approval status
  • --list — Lists all tasks with phase and next step
  • --create-task {name} — Creates task folder with .state=new, validates kebab-case, refuses duplicates
  • --transition {phase} — Validates and writes .state transitions, refuses illegal transitions, refuses past :awaiting_approval without --approve, validates required artifacts and forbidden artifacts
  • --approve — Transitions :awaiting_approval → :approved, records in .state.approvals, refuses if not in awaiting_approval sub-state
  • --validate-folder — Checks for out-of-order artifacts, flags manually created tasks
  • --audit — Four categories: out-of-order artifacts, state-artifact inconsistency, unauthorized git modifications, manually created tasks
  • --claim / --release — Multi-agent task claiming with .state.lock files, timeout, overclaiming
  • --next-available / --available — Work discovery for multi-agent, filters by agent role
  • --can-edit — Returns ALLOWED/DENIED based on current phase
  • --scope-check — Returns IN_SCOPE/OUT_OF_SCOPE for file paths
  • --same-session — Heuristic session check

2. Approval sub-states

  • Phases with approval: research, decomposition, design, test_design
  • Sub-states: {phase}:awaiting_approval and {phase}:approved
  • --transition refuses past :awaiting_approval without --approve
  • --approve records timestamp and approver in .state.approvals

3. Forbidden artifacts per phase

  • Full mapping from SPEC implemented in FORBIDDEN_ARTIFACTS dict
  • --validate-folder checks and reports violations
  • --transition refuses if forbidden artifacts exist

4. Multi-agent support

  • Agent Configuration parsed from .agent.md
  • .state.lock files with agent ID, phase, claimed timestamp, expiry
  • Configurable lock timeout (default 30 min)
  • --claim validates agent is configured for the phase
  • --next-available returns highest-priority unclaimed task matching agent phases

5. Tests: tests/test_status.py (25 tests)

  • Create task (valid, invalid names, duplicates)
  • State transitions (legal, illegal, approval gates)
  • Approval gates (approve, refuse wrong phase, record log)
  • Folder validation (valid, no state file, out-of-order artifacts)
  • Artifact validation (missing required, forbidden)
  • Show task (phase display, allowed/forbidden)
  • List tasks
  • Tool hooks (can-edit, scope-check)
  • Audit (manual tasks, clean tasks)

Files Created

  • scripts/status.py (980 lines)
  • tests/test_status.py (25 test cases)

Test Results

  • 183 tests passing (including all 25 new status.py tests)
  • Python compilation clean
