The pre-fix `bool(data.get("pass"))` returned `True` for `"false"` (non-empty string is truthy) — a verifier emitting `{"pass": "false", "score": 0.1}` was recorded as `pass=True`, advancing the loop on a failed verdict. Non-`"true"`/`"false"` strings fall through to `bool(raw_pass.strip())` for backwards compat (`"yes"` stays truthy; `""` stays falsy; `None`/`0`/`[]`/`{}` keep v1's `bool(...)` semantics). + - `score` field: now clamped to `[0, 1]` via `max(0.0, min(1.0, score))`. `NaN`, `Infinity`, and `-Infinity` (which `json.loads` accepts as bare tokens because `float(...)` happily returns `math.nan`/`inf`) default to `0.5` (neutral midpoint) via a `math.isfinite` guard. Non-numeric types (`None`, `[]`, `"high"`, etc.) and non-numeric strings default to `0.5` via a `try/except (TypeError, ValueError)` around `float(...)`. + - Pure-function change; no CLI surface; no schema change; no new deps (`math` is stdlib). Strict emitters (those already emitting `bool pass` and `0.0 ≤ score ≤ 1.0`) are unaffected. +- **`design/loops/technical.md` §7**: Documented the new coercion contract inline in the tick-flow step 7 (parse verdict). +- **`design/loops/functional.md` §10**: Updated the Verifier Contract section to note the runner's defensive coercion for `pass` strings and `score` clamping. +- **New tests**: `tests/test_parse_verdict.py` — 22 tests across 5 classes (`TestStrictBaseline`, `TestPassStringCoercion`, `TestScoreClamping`, `TestFenceBlockStillWorks`, `TestOptionalKeysPreserved`).

All inputs yield deterministic, documented results; no crashes; no silent truthy/coercion regressions vs v1. +- **Inline bug found and fixed during implementation**: the first iteration of the three-way branch set `verdict_pass = raw_pass.strip().lower() == "true"` — which mapped EVERY non-`"true"` string to False, breaking the SPEC R1 `bool(...)` fallback clause (a `"yes"` string would have become False, silently regressing v1). Fixed to the explicit `if "true" / elif "false" / else: bool(...)` form; test `test_other_truthy_string_pass` was added immediately to lock the contract. +- **Full suite**: **469 passed** (was 447; +22 new; 0 regressions). + +### Added — `.state.loop` file lock (task `add-state-loop-lock`) + +- **`scripts/status.py`**: New `_loop_lock(loop_path, exclusive=True)` context manager wrapping the read-modify-write cycle of `.state.loop` with a cross-process file lock (POSIX `fcntl.flock(LOCK_EX)`, Windows `msvcrt.locking(LK_LOCK, 1)`) on `/.state.lock`. Closes the TOCTOU races flagged in `add-status-brakes/ADVERSARIAL_BUG_REPORT.md` (A6) and `add-loop-runner/ADVERSARIAL_BUG_REPORT.md` (A2, A7) where concurrent ticks (two scheduler firings on the same loop) or a concurrent `--pause-loop` / `--approve --loop` write could overwrite a tick's iteration increment or lose an approve's `resumed_count` increment. Per-loop granularity; blocking acquire; no timeout in v1.1 (operators notice a wedged tick via `--loop-list` stale `last_tick_at`). +- **`scripts/status.py` callsites wrapped**: `cmd_pause_loop`, `cmd_resume_loop`, `cmd_approve_loop`, `cmd_check_gate` now acquire `_loop_lock` around their read-modify-write blocks. `--create-loop` intentionally unwrapped (no prior state to race against; create is name-unique-refused). `_disable_schedule` / `_enable_schedule` side-effect toggles moved OUTSIDE the lock to keep the critical section tight; the per-tick `--check-gate` self-skip on non-`running` state makes the transient ~100ms window harmless. +- **`scripts/loop-runner.py`**: Mirrored `_loop_lock` helper (no env bypass — the runner is the lock holder). Wraps the entire `cmd_tick` critical section from the `_gate` subprocess call through step-10's state write. `_read_state_loop` is invoked twice: once unlocked (fast-fail untracked) and once inside the lock (re-read fresh to capture any concurrent mutate). +- **Subprocess-deadlock avoidance (D-L6)**: When the runner spawns `status.py --check-gate` as a subprocess inside its held lock, status.py's own `cmd_check_gate` would otherwise deadlock waiting on the parent's held flock. Resolved by introducing the `$AUTOMATON_NO_LOOP_LOCK=1` env var, scoped ONLY to the `--check-gate` subprocess's env (set via `subprocess.run`'s `env` kwarg in `_gate`). status.py's `_loop_lock` checks this env var; if set, it yields without flocking (trusting the caller's outer lock). Harness subprocesses (Implement/Verify/Orchestrate) do NOT inherit the env var, so any `status.py --transition` calls the harness transitively invokes lock normally and serialize correctly. +- **Scope of the env var**: `$AUTOMATON_NO_LOOP_LOCK` is read-only-internal; the runner never sets it in `os.environ` globally, only in the `_gate` subprocess's explicit env dict. Manual CLI users who set it in their shell bypass locking (documented escape hatch; same trust boundary as "shell user can kill the runner"). +- **`design/loops/technical.md` §7**: Added a "Lock serialization" subsection documenting the lock shape, the env-bypass mechanism, the re-entry forbidding contract, and the harness-contract implication (loop-control commands deadlethal inside a tick; task commands are safe). +- **`AGENTS.md`**: Updated "State Enforcement — Loops (v1)" section to mention `_loop_lock` and the env var. +- **`README.md`**: Added a row in the loop engineering monitoring table mentioning `.state.lock` per-loop serialization. +- **Stdlib-only**: `fcntl` (POSIX) and `msvcrt` (Windows) are stdlib. No `filelock` package. No new pip deps. +- **Backwards-compatible**: existing scripts that don't invoke `--pause-loop` / `--resume-loop` / `--approve --loop` / `--check-gate` concurrently are unaffected. Primary lock surface is per-tick blocking when schedulers fire on the same loop concurrently. +- **New tests**: `tests/test_state_loop_lock.py` -- 7 tests covering (1) concurrent-acquire serialization, (2) clean-release + re-acquire, (3) release-on-exception, (4) per-loop granularity, (5) `--create-loop` doesn't create `.state.lock` (D-L3) but `--check-gate` does, (6) `--pause-loop` blocks under concurrent lock holder, (7) `cmd_tick` holds the lock across the harness subprocess while `--approve --loop` blocks. All use `tmp_path`, stdlib only, no live LLM. +- **Adversarial findings**: A1 (concurrent approve: race closed, only 1 of 5 won, `resumed_count` incremented once), A2 (concurrent pause: idempotent but consistent), A3 (lock releases on mid-tick exception: verified), A4 (harness calls loop-control inside tick: theoretical deadlock, LOW severity, deferred to harness-integration contract docs follow-up), A5 (manual env var escape hatch: documented), A6 (orphaned `.state.lock` after crash: benign; POSIX auto-releases flock on process exit), A7 (NFS: documented assumption), A8 (cyclomatic complexity: acceptable). No blockers. +- **Full suite**: **447 passed** (was 440; +7 new; 0 regressions). + +### Fixed — harness command template (task `fix-harness-command-template`) + +- **`scripts/loop-runner.py`**: Fixed the broken default `harness.command`. The old default `["opencode", "run", "--prompt-file", "{prompt}", "--cwd", "{cwd}"]` used flags that do not exist in `opencode run` (`--prompt-file`, `--cwd`) — the v1 runner has only been exercised via mocked subprocess tests, so the bug was never caught. New default is `["opencode", "run", "--dir", "{cwd}", "{prompt_content}"]`. Introduces a new `{prompt_content}` substitution token that carries the resolved prompt's text as a single argv element under `subprocess.run` list mode (no shell expansion, safe for prompts containing quotes/special chars). +- **`{prompt}` and `{cwd}` tokens retained**: backwards-compatible. Users with custom `harness.command` in `loop.json` using these tokens are unaffected. +- **`UnicodeDecodeError` now caught** alongside `OSError` when reading the resolved prompt file (defensive; falls back to empty prompt content rather than crashing mid-tick). +- **Harness-agnostic contract preserved and extended**: runner core has zero harness awareness; the new `{prompt_content}` token covers harnesses that prefer a message argument (Pi Dev, aider, any CLI taking a prompt as a positional). Non-opencode users override `harness.command` in `loop.json` (e.g. `["pi", "run", "--cwd", "{cwd}", "{prompt_content}"]`). D8 (no model/provider inspection) intact. +- **`design/loops/technical.md` §8 and §9**: Updated default command shape; documented the new `{prompt_content}` token alongside existing `{prompt}`/`{cwd}`/`{output}`/`{artifact}` tokens; added Pi Dev, aider, and generic shell-wrapper examples in `loop.json` form. +- **`templates/loops/self-improvement/loop.json`**: Updated `harness.command` to the new default. +- **Test scaffolding updates**: `_make_loop` helpers in `tests/test_loop_runner.py`, `tests/test_blast_radius.py`, `tests/test_goal_mode.py`, `tests/test_loop_templates.py` now write loop-local prompt stubs (containing role-marker content `prompt: `) when the framework prompt at `~/.automaton/prompts/` does not already exist. This preserves the substring-matcher strategy used by tick-flow tests while not overriding real framework prompts (which contain `{current_task}` etc. substitution tokens). Custom-`{prompt}`-command tests in `test_goal_mode.py` updated their matcher substrings from `test-impl`/`test-verify`/`test-orch` to `implement-prompt`/`verify-prompt`/`orchestrate-prompt` (the resolved temp-file path contains those markers). +- **New tests**: `tests/test_harness_command.py` -- 7 tests covering: default uses `--dir` not `--cwd`/`--prompt-file`; default passes prompt content as last argv element; prompt content preserves single quotes/double quotes/dollar signs as a single argv element; `{prompt}` token still available for custom commands; `{cwd}` token still works in custom commands; empty `command` falls back to the new default; Pi Dev-shaped command substitution (proves the substitution mechanism is harness-agnostic — any binary works). +- **Backwards-compat correction**: Updated the v1 `add-loop-runner` CHANGELOG bullet that documented the old default — no retroactive edit to the released entry shape, but the new `### Fixed` entry supersedes the default-command wording. The default command works end-to-end now. +- Full suite: **440 passed** (was 433 baseline; +7 new). + +### Changed — completed tasks moved to `tasks/complete/` (task `move-completed-tasks-to-complete-folder`) + +- **`scripts/status.py`**: `--transition complete` now moves the task directory from `tasks//` to `tasks/complete//`. `_task_dir` has a fallback to find completed tasks. `--list` and `--audit` exclude completed tasks (visible only via `--task ` fallback). +- **New tests**: `tests/test_move_completed.py` -- 9 tests covering directory move, fallback, listing exclusion, create-task refusal, and transition refusal from complete. Full suite: 433 passed. + +### Fixed — install/update flow (task `fix-install-update-flow`) + +- **`scripts/install.sh`**: Replaced hardcoded private git URL with user-supplied `GIT_URL="${1:-}"` argument (D11). Refuses with usage and irreversibility warning if absent. Fixed `.venv` cwd bug: venv now created in `$FRAMEWORK_DIR/.venv` instead of CWD. Added Windows venv path support (`.venv/Scripts/python.exe`). Uses `"$VENV_PY" -m pip` for cross-platform pip invocation. Added `status.py --version` smoke test after install. +- **`scripts/update.sh`**: Changed hook installation from `ln -sf` (symlink) to `cp` + `chmod +x` (copy), matching `install-hooks.sh`. +- **`scripts/upgrade.sh`**: Replaced all `ln -sf` and symlink-checking logic (`readlink`, `-L`) with `cp` + `chmod +x`. Simplified hook-exists warning to point to `install-hooks.sh`. +- **New tests**: `tests/test_install_update_flow.py` -- 15 tests covering git URL, venv paths, version check, and hook consistency. Full suite: 424 passed. + +### Added — loop engineering v1, self-improvement loop default-on (task `add-self-improvement-loop`) + +- **`scripts/install.sh`**: after clone and guard registration, creates and schedules the self-improvement loop (`--create-loop self-improvement --from-template self-improvement --project "$FRAMEWORK_DIR"` + `--install-schedule self-improvement --interval 3600`). Both commands use `|| true` so the framework continues to work even if loop creation fails. Prints a user-facing message with opt-out instructions (`--pause-loop self-improvement`). +- **`scripts/update.sh`**: idempotent bootstrap for existing users.

Falls back to raw `prompt_ref` when file not found (backward compat). `{artifact_content}` reads the file at `extras["artifact"]` and substitutes its content (empty string if missing). +- **`_invoke_harness` extended**: new optional `loop_path` and `tick_num` params. When `loop_path` is provided, calls `_resolve_prompt` before building the harness command. All three call sites in `cmd_tick` (implement, verify, orchestrate) now pass `loop_path` and `tick_num`. +- **New prompt files**: `prompts/loop-implement.md` (Implement role with task_brief/criteria/hint tokens, ALLOWED/FORBIDDEN sections), `prompts/loop-verifier.md` (Verify role with strict JSON output, score rubric 0.0-1.0, artifact_content token), `prompts/loop-orchestrate.md` (Orchestrate role with verdict token, phase transition logic, no-edit/no-auto-approve rules). +- **`templates/loops/ci-triage/loop.json`**: `roles` filled from `null` to `{"prompt": "loop-implement.md"}` etc. +- **`templates/loops/self-improvement/loop.json`**: new template with `work_source: audit`, `blast_radius.use_worktree: true`, `file_scope: ["scripts/", "prompts/", "tests/", "design/"]`, `brakes.max_iterations: 10`, `score_plateau_window: 3`. +- **README.md**: new "Loop Engineering" onboarding section (quick start, tick cycle, configuration, monitoring, halt/resume). +- **`design/loops/technical.md` section 8**: documented prompt resolution and token substitution flow. +- **New tests**: `tests/test_loop_templates.py` -- 18 tests covering R1-R6 (resolve_prompt, prompt file content, ci-triage template, self-improvement template, tick integration). Full suite: 393 passed. +- **Test infrastructure**: updated `tests/test_loop_runner.py`, `tests/test_blast_radius.py`, `tests/test_goal_mode.py` to use non-existent prompt refs (`test-impl.md` etc.) so `_resolve_prompt` fallback path is exercised in those tests. Added loop prompts to self-consistency test exclusion set. + +### Added — loop engineering v1, blast-radius scheduler (task `add-blast-radius-scheduler`) + +- **`scripts/loop-runner.py` extended**: `_ensure_worktree(state, cfg, loop_path, project_dir)` creates a per-loop git worktree at `/worktree` on branch `loop/` when `blast_radius.use_worktree` is true (default) and no worktree exists yet. Records `worktree_path` and `worktree_branch` in `.state.loop` atomically. Reuses existing worktree on subsequent ticks. Falls back to project root with a WARNING log when: not a git repo, git binary missing, or `git worktree add` fails. Handles branch-already-exists by retrying without `-b`. Stale `worktree_path` (directory deleted) is cleared and worktree recreated. +- **New tests**: `tests/test_blast_radius.py` -- 15 tests covering worktree creation, reuse, fallback, branch-exists retry, state consistency, tick integration, platform paths, and backward compat.

Optional `work_source.project` overrides the audit target. + - `"backlog"`: reads `/design//BACKLOG.md` (`work_source.area` defaults to `"loops"`); picks the topmost `- [ ]` item. Empty backlog → SKIP `no_work`. +- **Goal-oriented substitution tokens**: three new tokens available in `harness.command`: + - `{task_brief}` -- from `/RESEARCH.md` or `DESIGN.md` or `SPEC.md` (first hit), capped at 4k tokens. + - `{acceptance_criteria}` -- from `loop.json` `acceptance_criteria` (string OR list joined by newlines), capped at 2k tokens. + - `{next_hint}` -- from `state.last_verdict.next_hint` (empty on first tick / after `--approve`), capped at 1k tokens. + - Closes the `next_hint` feedback loop: tick N's verifier hint becomes tick N+1's Implement/Verify context (D7 graded verifier feedback). +- **`_truncate_tokens(text, max_tokens)`** stdlib-only approximate cap (4-chars-per-token heuristic, `…[truncated]` marker). No tokenizer dependency. +- **`scripts/status.py --audit --json`**: machine-readable audit mode.

Each violation carries `category`, `severity` (`high`/`med`/`low`), `task`, `message`, `resolved: false`. Existing human-readable `--audit` output is unchanged when `--json` is absent. Backed by new `_audit_collect` and `_audit_category3_paths` helpers. +- **`templates/loops/ci-triage/loop.json`**: added `"work_source": {"kind": "single"}` and an `"acceptance_criteria"` example so the template is self-documenting. +- **Backward compat**: missing `work_source` or unknown `kind` falls back to `"single"` with a `.state.log` WARNING entry. Existing task-3 fixtures tick identically. +- **New tests**: `tests/test_goal_mode.py` -- 26 tests covering R1-R8 and one regression.

Calls `status.py --check-gate` first; any non-ok gate exits 0 (clean scheduler exit). Calls `vram_detect.py --loop-mode --json` before any harness subprocess; refuses below the 16k floor (D13) with `human_intervention`. Idempotent in failure -- pre-step-10 crashes do not corrupt `.state.loop` or advance `iteration_count`. +- **Graded verifier protocol**: `parse_verdict` accepts raw JSON, ```json fenced blocks, or JSON with `//`/`#` line comments. Required keys: `pass` (bool), `score` (float). Optional: `reasons` (list[str]), `next_hint` (str). Parse failure halts as `verifier_failed` without advancing state. +- **Harness command substitution**: `loop.json` `harness.command` (list of strings) with tokens `{prompt}`, `{cwd}`, `{output}`, `{artifact}`, `{verdict}`, `{current_task}`, `{current_phase}`. Default command (v1.1, see `fix-harness-command-template` above): `["opencode", "run", "--dir", "{cwd}", "{prompt_content}"]` (old default with `--prompt-file`/`--cwd` was non-functional; fixed in v1.1). Stdlib only, no new pip deps. +- **Score history capping**: per-tick score appended to `score_history`, capped at `brakes.score_plateau_window` (oldest dropped). Score plateau halts via the next tick's `--check-gate`. +- **Tick log**: every state-changing op appends an ISO-timestamped `TICK pass= score= iter=` line. Daemon mode appends `DAEMON_STOPPED` on KeyboardInterrupt. +- **New tests**: `tests/test_loop_runner.py` -- 18 tests across 7 classes cover R1--R8.

All halts require human `--approve --loop` to resume; no auto-approve path (D4). +- **Tiered role budgets**: three session roles (`Implement:`, `Verify:`, `Orchestrate:`) with explicit context tiers. 16k floor hard refuse (D13). Session divergence mandatory; model divergence only when `Verify:` != `Implement:` (D12). +- **Per-loop git worktree** as blast radius default (D2); `--no-worktree` opt-out. +- **Native scheduler generator**: `platform.system()`-dispatched `launchd` / `crontab` / `schtasks` unit generation via `status.py --install-schedule` (D1); `--daemon` opt-in fallback. +- **Self-improvement loop template** at `templates/loops/self-improvement/`, **default-on at install** (D21).

Blast Radius + +A loop runs in a **per-loop git worktree** at `.automaton/loops//worktree/`, branched from the project's main branch on first tick. All edits from the loop land in the worktree; merging back to main is a human action. + +`--no-worktree` is an opt-out for users who want loops to edit the primary checkout directly (e.g. in CI environments with no git state). v1 documents this flag; the default is worktree-on. + +`status.py --can-edit` is extended: edits are allowed only if the path is under the loop's worktree (or the loop has `--no-worktree`). Pre-existing `--can-edit` semantics for harness integration are preserved. + +## 8. Schedules + +Tick sources, in priority order: + +1. **Native OS unit** (default). `status.py --install-schedule ` emits: + - macOS: a `~/Library/LaunchAgents/com.automaton.loop..plist` + - Linux: crontab line via `crontab -l | ... | crontab -` + - Windows: a `schtasks /create` invocation +2. **`--daemon`** (opt-in). Runs `loop-runner.py --mode tick` on a Python `sleep` loop. Useful in CI containers and on shared servers without cron access. +3. **Manual**: `python loop-runner.py --mode tick --loop `. Always available. + +A loop's `--install-schedule` produces a small platform dispatcher script at `.automaton/loops//automaton-loop-tick.sh` that re-enters `loop-runner.py --mode tick`. The OS unit calls `automaton-loop-tick.sh`. This keeps the native unit trivial and inspects-free; all logic lives in Python. + +## 9. Loop Configuration File + +Each loop is configured at `.automaton/loops//loop.json`. Exact schema is in `technical.md` §2. Key fields: + +- `name`, `description` +- `work_source`: `{kind: "audit" | "backlog" | "single", project: optional, area: optional}` +- `acceptance_criteria`: optional string OR list of strings — fed to the verifier prompt as `{acceptance_criteria}` (capped at 2k tokens); the loop's "goal" +- `roles`: `{implement: {...}, verify: {...}, orchestrate: {...}}` — role → prompt + tier +- `brakes`: `{max_iterations: N, max_budget_usd: optional, score_plateau_window: N}` +- `blast_radius`: `{worktree: bool, file_scope: [paths], base_branch: str (optional, default "main")}` +- `outputs`: `{retention: N}` — keep last N tick groups in `outputs/` (default 20, 0 = unlimited, v1.1 `add-outputs-retention`) +- `schedule`: `{kind: "native" | "daemon" | "manual", interval_seconds: N}` + +## 10. Verifier Contract + +`Verify:` returns a JSON object of **exactly** this shape (graded verdict, P6): + +```json +{ + "pass": false, + "score": 0.62, + "reasons": ["..."], + "next_hint": "..." +} +``` + +- `pass` (bool) definitive. The runner also accepts the strings `"true"`/`"false"` (case-insensitive, whitespace-stripped) for defensive compatibility; other non-bool types defer to `bool(...)` (v1.1 `harden-parse-verdict`). +- `score` (0.0–1.0) is the signal for the circuit-breaker: if N consecutive ticks have a flat or monotonically-decreasing score, halt as `verifier_failed`. The runner clamps any out-of-range numeric score to `[0, 1]`; NaN, ±Infinity, and non-numeric values default to `0.5` (v1.1 `harden-parse-verdict`). +- `reasons` is human-legible, written to the loop's tick log. +- `next_hint` is fed back into the next tick's `Implement:` session as the only persistent context. Capped at 1k tokens by the runner; longer hints are truncated. + +The verifier prompt is intentionally minimal (see `technical.md` §5) — a fresh-context LLM verifier should not need to load the framework's 11-file context to grade a single artifact. + +## 11. Self-Improvement Loop (Scope 1, default-on) + +A pre-shipped loop template at `templates/loops/self-improvement/` ticks against `status.py --audit` output for the framework's *own* repo (`~/.automaton/`). Its `Implement:` role picks the highest-severity audit violation, drafts a fix in a worktree, transitions the affected task (or creates a new task via `status.py --create-task` when the violation is a new issue), runs its phases, and hands off to a human reviewer. + +At install time, `install.sh` calls `status.py --create-loop self-improvement --from-template self-improvement` and `--install-schedule self-improvement --interval 3600`. Users can disable with `status.py --pause-loop self-improvement` (added in v1). + +This is the literal seed of self-management: a loop that runs on the framework's own audit output. It is *not* drafting designs — it runs against documented audit cleanup work only. + +## 12. Cross-Loop Task Claim (v1.1) + +Prevents two loops from racing to claim the same task (closes `add-status-brakes/ADVERSARIAL_BUG_REPORT.md` A2). The runner calls `status.py --claim-loop-task --task ` inside `_loop_lock` after `_find_work` picks a candidate (step 3.5 in tick flow). The claim command scans all running/paused loops' `.state.loop.current_task` and refuses if another loop already owns the target task. Self-ownership is idempotent. The claim subprocess uses the same `$AUTOMATON_NO_LOOP_LOCK` env bypass as `--check-gate` to avoid deadlock on the parent's held flock. + +**Release**: after the orchestrate subprocess (step 9.5), the runner re-reads the task's `.state`. If the phase is `complete` or `human_intervention`, `current_task` is cleared to `None` — the task is released for other loops. Non-terminal phases leave the claim intact. + +**Design decisions**: +- Claim is a `status.py` subprocess, not an in-process helper (single authority for loop state). +- Cross-loop scan is advisory (no cross-loop lock). Race window is one tick; self-healing on next tick. +- `paused` and `halted` loops retain their claim (resumed loop resumes without re-claiming). +- Release is the runner's responsibility, not the orchestrator's. Runner re-reads task state after orchestrate; terminal → clear. + +## 13. v1.1 (deferred from this scope) + +- A **design-update loop** template (Scope 2) that keeps `design//*.md` in sync with code +- `test_design_drift.py` discipline + dashboard "Loops" panel +- `contracts/loop-integration.md` +- `last-read-sha` comprehension-debt tracking +- Tier 2 context-sizing cleanup (the first real work-stream the loops pick up) + +These are listed in `design/loops/BACKLOG.md` so the self-improvement loop has a work queue from day one, but they are not implemented by v1. + +## 14. Harness Compatibility + +v1 loops work with any harness that can (a) run a session against a given prompt and (b) write the resulting artifact to a path. The `Orchestrate:` role is the only role that ever calls `status.py`; this means `status.py` integration is bounded to one session per tick. Concrete harness adapters are out of scope for v1 — loops are driven by `loop-runner.py` invoking the user's existing harness as a subprocess. + +## 15. Success Criteria for v1 + +1. A single capped loop runs unattended for ≤ N ticks without human involvement and halts cleanly on one of the five deaths. +2. A human `--approve` resumes a halted loop, and the resume increments `__resumed_count` not `__iteration_count`. +3. End-to-end test `tests/test_loops.py` passes, covering: one terminating ticket (PASS), one `verifier_failed` halt, one `iterations_exhausted` halt, one `drift_detected` halt, one `--approve` resume. +4. The self-improvement loop installs default-on and ticks once against a seeded audit violation in a temp fixture, producing a worktree + a transition not an edit to main. +5. `pytest tests/ -v` is still green for the framework's pre-existing test suite (no regression). + +## 16. Locked Decision Index + +All decisions referenced by `(Dn)` above are recorded in v1 scope conversation (this session). They are non-negotiable for v1 implementation.

Anything else halts the tick immediately. +2. **Iteration count** — `iteration_count < max_iterations` from `loop.json`. +3. **Budget** — if `max_budget_usd` is set (informational, remote-only), check the harness's reported cost (best-effort: read from a `cost.json` the harness writes; absence is non-fatal). Below 16k context = hard refuse (D13). +4. **Task phase** — if `current_task` is set, that task's `.state` must still be one of the phases this loop is allowed to operate on. If the task has transitioned out (e.g. to `human_intervention` by some other path), halt as `human_intervention`. +5. **Worktree drift** — if worktree branch diverges from main in a way that indicates the loop wrote files outside its scope (checked via `git diff --name-only main...HEAD` restricted to `file_scope`), halt as `drift_detected`. +6. **Score plateau** — last N entries in `score_history` are flat or monotonically decreasing (where N = `score_plateau_window`). Trip → halt as `verifier_failed`. + +All halts atomically set `status=halted`, `halt_reason=`, write to `.state.log`, and call `--pause-loop`'s schedule-disable step (see §6). + +## 5. Verifier Prompt Shape (`loop-verifier.md`) + +Intentionally minimal — a fresh-context LLM should be able to grade a single artifact without loading the framework's 11-file context. + +``` +# Loop Verifier — {loop_name} + +You are grading one artifact for loop `{loop_name}`. + +## Task context (read-only) +{task_brief} # from .automaton/tasks//RESEARCH.md or DESIGN.md, capped at 4k tokens + +## Artifact under review +{artifact_content} # the file(s) the Implement: role just wrote + +## Last tick's hint +{next_hint} # capped at 1k tokens, may be empty + +## What to check +{acceptance_criteria} # from loop.json, capped at 2k tokens + +## Output (strict JSON, no prose) +{ + "pass": , + "score": <0.0-1.0>, + "reasons": ["..."], + "next_hint": "..." +} + +Score rubric: +- 1.0 = acceptance_criteria fully satisfied, no defects +- 0.7 = functionally complete, minor defects not in criteria +- 0.4 = partial progress, criteria partially addressed +- 0.0 = no useful progress, or artifact is empty/missing +``` + +Tier budget (from `loop.json`): **4k minimum, 16k floor** (D13). Below 16k the runner refuses before invoking the verifier — no tiny-context verifier ever runs. + +`Implement:` prompt is similar but emits the artifact to a path, not JSON. `Orchestrate:` prompt loads the verdict JSON and calls exactly one `status.py` operation (no edits). + +## 6. Scheduler Unit Generation (`--install-schedule`) + +Platform detection via `platform.system()`: +- **Darwin** → `~/Library/LaunchAgents/com.automaton.loop..plist` with `StartInterval` = `interval_seconds`. The plist's `ProgramArguments` calls `automaton-loop-tick.sh` (generated in the loop dir, see below). `--pause-loop` renames the plist to `.disabled` (Launch Agents don't honor a disabled bit portably). `--resume-loop` renames it back and `launchctl load`s it. + +- **Linux** → `crontab -l` is read, lines for this loop removed, new line added (`*/N minutes * * * * `), `crontab -` written back. `--pause-loop` removes the line; `--resume-loop` re-adds it. + +- **Windows** → `schtasks /create /tn "AutomatonLoop_" /tr "" /sc minute /mo /f`. `--pause-loop` calls `schtasks /change /tn ... /disable`; `--resume-loop` calls `/enable`. +`automaton-loop-tick.sh` (generated in the loop dir, chmod +x) is 3 lines. The name is self-documenting: when the scheduler unit (plist ProgramArguments / cron line / schtasks `/tr`) references the file path, the filename alone conveys "this is automaton's loop-tick entry point" — no need to parse the script to know its role. + +```bash +#!/usr/bin/env bash +cd "" +python3 "/scripts/loop-runner.py" --mode tick --loop "" +``` + +This keeps the OS-specific unit trivial. All logic (gate check, role invocation, verdict parse, brakes) lives in Python. + +`--daemon` opt-in: `loop-runner.py --mode daemon --loop ` runs a `time.sleep(interval)` loop calling `--mode tick` per iteration.

The lock file is `/.state.lock` (per-loop granularity). POSIX uses `fcntl.flock(LOCK_EX)`; Windows uses `msvcrt.locking(LK_LOCK, 1)`. Blocking acquire, no timeout in v1.1 (operators notice a wedged tick via `--loop-list` stale `last_tick_at`). + +The same `_loop_lock` wraps the read-modify-write blocks in `cmd_pause_loop`, `cmd_resume_loop`, `cmd_approve_loop`, and `cmd_check_gate` (in `status.py`). `--create-loop` is intentionally unwrapped — there is no prior state to race against. + +**Subprocess-deadlock avoidance (D-L6)**: the runner's `_gate` call spawns `status.py --check-gate` as a subprocess. If status.py's `cmd_check_gate` also acquired `_loop_lock`, it would deadlock waiting on the parent runner's held flock. To avoid this, the runner passes `$AUTOMATON_NO_LOOP_LOCK=1` in that subprocess's env ONLY (scoped to the `_gate` subprocess; harness subprocesses do NOT inherit it). status.py's `_loop_lock` checks the env var; if set, it yields without flocking (trusting the caller's outer lock). Standalone CLI users don't set the env var, so `--check-gate` invoked manually locks normally and serializes against `--pause-loop` etc. + +**Same bypass for claim subprocess**: `--claim-loop-task` (step 3.5) is also spawned from inside the runner's `_loop_lock`. The runner passes `$AUTOMATON_NO_LOOP_LOCK=1` in the claim subprocess env for the same reason — `cmd_claim_loop_task` acquires `_loop_lock` in status.py, but the runner already holds it. The bypass env is set only for this subprocess; standalone `--claim-loop-task` invocations (e.g. from `--can-continue` or future operator tooling) lock normally. + +**Forbidding re-entry**: `_loop_lock` is NOT re-entrant across processes. Audit callsites to ensure no nested `_loop_lock` within the same `with` block. All v1.1 callsites are flat — no nested locks. + +**Harness contract implication**: harnesses invoked via `harness.command` should NOT call loop-control commands (`--pause-loop`, `--resume-loop`, `--approve --loop`, `--check-gate`) from inside a tick — that would deadlock waiting on the parent runner's lock. Task commands (`--transition`, `--approve --task`, `--can-edit`, `--scope-check`, `--task`, `--claim`) do NOT touch `.state.lock` and are safe. Future work: add this to `contracts/harness-integration.md`. + +### Outputs retention (v1.1 — `add-outputs-retention`) + +To bound `outputs/` directory growth (O5 from `add-loop-runner/BUG_REPORT.md`), the runner runs GC after step 10 inside `_loop_lock`, retaining only the last N tick groups (default 20). Configured via `loop.json`: + +```json +"outputs": { + "retention": 20 +} +``` + +- `retention` = 0 disables GC (unlimited, v1 behavior). Negative coerces to 0 with WARNING. +- GC iterates `outputs/`, parses `tick{N}-` prefix via `^tick(\d+)-` regex, computes `cutoff = max_seen - retention + 1`, deletes files with tick index < cutoff. +- Non-tick files (no `tick{N}-` prefix) are preserved. +- GC failure (permissions, file-not-found mid-iteration) is logged as WARNING and swallowed — never crashes the tick. + +## 8. Harness Invocation + +`loop-runner.py` invokes the user's harness via a single configured command in `loop.json`: + +```json +"harness": { + "command": ["opencode", "run", "--dir", "{cwd}", "{prompt_content}"], + "prompt_var": "{prompt}", + "cwd_var": "{cwd}", + "output_var": "{output}" +} +``` + +v1.1's default `harness.command` is `opencode run` -- matching the framework's primary harness -- but the shape is generic. The runner substitutes the following tokens into the `command` list (single argv element per token, no shell expansion): + +- `{prompt}` -- resolved prompt file path (loop-local override or framework default). Kept for backwards compat and harnesses that prefer a file path. +- `{prompt_content}` -- the resolved prompt file's text content as a single argv element. Safe under `subprocess.run` list mode; no shell quoting needed. Used by the default command since `opencode run` takes the message as a positional argument and has no `--prompt-file` flag. +- `{cwd}` -- the working directory the harness should run in (the loop's project root or worktree). +- `{output}`, `{artifact}` -- role-specific extras (the implement output path handed to verify). +- `{verdict}`, `{current_task}`, `{current_phase}`, etc. -- other runtime extras; see `_resolve_prompt` below. + +The default command does NOT hardcode a `--model` flag; the spawned `opencode run` inherits the model from the project/user config. Users who want a per-loop model override (e.g. a local LLM for ticks) set `harness.command` in their `loop.json`: + +```json +"harness": {"command": ["opencode", "run", "--model", "local-mlx/...", "--dir", "{cwd}", "{prompt_content}"]} +``` + +The runner core has zero knowledge of which harness is invoked (D8: framework never inspects model/provider). Concrete adapters for non-opencode harnesses (Pi Dev, aider, Cursor, Cline, Copilot) are out of scope for v1 -- users override `harness.command` to match their harness's CLI shape. Examples: + +```json +// Pi Dev +"harness": {"command": ["pi", "run", "--cwd", "{cwd}", "{prompt_content}"]} + +// aider +"harness": {"command": ["aider", "--message", "{prompt_content}", "--yes"]} + +// Generic shell wrapper (any tool that reads prompt from stdin) +"harness": {"command": ["sh", "-c", "cat {prompt} | my-tool --cwd {cwd}"]} +``` + +No new harness adapter is written in v1.1. + +### Prompt Resolution and Token Substitution + +Before building the harness command, the runner calls `_resolve_prompt(prompt_ref, extras, loop_path, tick_num, role)`: + +1. **File search**: checks `/` first (loop-local override), then `~/.automaton/prompts/` (framework default). If neither exists, returns the raw `prompt_ref` string (backward compat -- the harness receives the raw ref). +2. **Content substitution**: reads the prompt file and substitutes content-level tokens in the prompt text: + - `{task_brief}`, `{acceptance_criteria}`, `{next_hint}` -- from the work source and `.state.loop` + - `{current_task}`, `{current_phase}` -- from `.state.loop` + - `{verdict}` -- the JSON verdict from the verifier (orchestrate role only) + - `{artifact_content}` -- reads the file at `extras["artifact"]` (the implement output path) and substitutes its full text; empty string if the file is missing (verify role only) +3. **Temp file write**: writes the substituted content to `/outputs/tickN--prompt.md`. +4. **Return**: the temp file path replaces `{prompt}` in the harness command template. + +This means the harness receives a fully-resolved prompt file with all context baked in -- no runtime token substitution needed inside the harness. The loop-local override path (`/`) allows per-loop prompt customization without modifying the framework prompts. + +## 9. Self-Improvement Loop Template + +`templates/loops/self-improvement/loop.json`: + +```json +{ + "name": "self-improvement", + "description": "Ticks against status.py --audit on the framework's own repo", + "work_source": {"kind": "audit", "project": "~/.automaton/"}, + "roles": { + "implement": {"prompt": "loop-implement.md", "tier": 16000}, + "verify": {"prompt": "loop-verifier.md", "tier": 8000}, + "orchestrate": {"prompt": "loop-orchestrate.md", "tier": 4000} + }, + "brakes": { + "max_iterations": 10, + "max_budget_usd": null, + "score_plateau_window": 3 + }, + "blast_radius": {"worktree": true, "file_scope": ["scripts/", "prompts/", "tests/", "design/"]}, + "acceptance_criteria": [ + "Audit findings resolved (no outstanding Cat-1/Cat-2/Cat-4 violations on the resolved task)", + "All R-numbers from the task SPEC.md implemented", + "Tests pass with no regressions", + "Pipeline driven to complete" + ], + "harness": { + "command": ["opencode", "run", "--dir", "{cwd}", "{prompt_content}"], + "prompt_var": "{prompt}", + "cwd_var": "{cwd}", + "output_var": "{output}" + }, + "schedule": {"kind": "native", "interval_seconds": 3600} +} +``` + +Installs default-on at `install.sh` time: `status.py --create-loop self-improvement --from-template self-improvement --project "$FRAMEWORK_DIR"` then `status.py --install-schedule self-improvement --interval 3600 --project "$FRAMEWORK_DIR"`.

A real `--mode tick` would fail on first invocation. + +**Fix**: new `{prompt_content}` substitution token (single argv element under `subprocess.run` list mode; safe for any prompt text including quotes/special chars). New default: `["opencode", "run", "--dir", "{cwd}", "{prompt_content}"]`. `{prompt}` (file path) and `{cwd}` retained for backwards compat. + +**Harness-agnostic contract**: preserved and extended. Runner core has zero harness awareness (D8 intact).Pi Dev / aider / Cursor / Copilot / Cline / generic shell wrapper all work via `loop.json` `harness.command` override.

The loop name is validated by `_is_kebab_case` in `status.py --create-loop` (rejects non-kebab-case names, including slashes). So the branch name is always `loop/`.

The second tick falls back to project root. The first tick succeeds and records the worktree. No state corruption (atomic write; last-writer-wins, but the second write doesn't happen because the fallback path doesn't write state). Next tick: both see the worktree exists and reuse it.

It's passed as a separate argv element to `subprocess.run(["git", "worktree", "add", path, "-b", branch])`. No shell invocation (`shell=False` by default in `subprocess.run` with list args). A branch name starting with `-` would be interpreted as a git flag, but `_is_kebab_case` requires alphanumeric + hyphens + dots + underscores, and the `loop/` prefix ensures the branch never starts with `-`. PASS + +### A6 -- Can a symlink at `/worktree` redirect file writes? +If an attacker creates a symlink from `/worktree` to `/etc`, `git worktree add` would fail (git refuses to use existing paths).

A hostile `area` value like `../../etc` would resolve to `/design/../../etc/BACKLOG.md` = `/../etc/BACKLOG.md` -- a path outside the project. However, the file must exist and contain `- [ ]` lines to produce a task name. The attacker would need write access to place a BACKLOG.md there, which already implies filesystem access. The runner doesn't write to the backlog path; it only reads.

If the command template includes `{task_brief}` as a CLI arg (e.g. `--brief {task_brief}`), the full task brief text appears in the process argv, visible via `ps` on multi-user systems. This is a config decision (the operator chose to pass it as a CLI arg). The default command does not include `{task_brief}`. The recommended pattern (task 6) is to have the prompt file itself contain `{task_brief}` -- but the runner doesn't substitute into prompt file content, only into the command template. PASS (operator config responsibility). + +### A5 -- Can a hostile `--audit --json` output inject a task name that escapes the tasks/ dir? +`_find_work_audit` uses the `task` field directly as `current_task`. If a hostile audit JSON returns `task: "../../../etc/passwd"`, the runner sets `state["current_task"] = "../../../etc/passwd"`. Downstream, `_task_dir_for(name, project_dir)` constructs `/../../../etc/passwd` -- a path outside tasks/. However, the runner only reads from this path (`_read_task_brief` checks `f.exists()` before reading) and passes the name as a substitution token. No writes occur. The orchestrator might call `status.py --task ../../../etc/passwd` but status.py's own validation would reject the path.

The default harness command (`opencode run --prompt-file {prompt} --cwd {cwd}`) does not contain `{task_brief}` etc., so the tokens are only useful when a loop config explicitly adds them to its harness command.

The runner's step 10 increments `iteration_count` only after the gate has passed. If the gate passed at iteration N (count=N), the tick runs, count becomes N+1. Next tick the gate sees count=N+1; if that exceeds max, it halts. So the runner increments AT MOST once per gate-pass. ✅ Defended. + +BUT: there's a TOCTOU window. Between `--check-gate` returning ok at iteration 9 (max=10) and the runner's step 10 writing iteration_count=10, a **concurrent second tick** could also pass the gate at count=9 and increment to 10. Both ticks would then run. Loop `max_iterations=10` could fire 11 ticks. **Window:** the OS scheduler interval typically >> tick duration, so this requires two schedulers firing the same loop concurrently (user error). Halt is not corrupted; the next gate halts `iterations_exhausted` correctly. + +**Mitigation:** documented runbook says "one scheduler per loop".

Not blocking. + +### A3 — Can the orchestrator role itself escape enforcement? +The orchestrator role is spawned with full substitution and runs in the same cwd as the verifier. It's expected to call `status.py --transition` itself. If a hostile orchestrator calls `status.py --transition` on a task the loop doesn't own, status.py's R8 halt-refusal only kicks in if the owning loop is halted — a non-halted loop's orchestrator could transition arbitrary tasks. **This is the runner contract:** the orchestrator's prompt (task 6) must restrict it to `current_task`. The runner does not enforce orchestrator behavior beyond passing it the verdict and current_task. The defense is prompt-based + the file_scope gate (`--can-edit --loop --file`) for any file edits. ✅ Defended by layered enforcement (prompt + can-edit + R8). + +### A4 — Can a hostile harness command execute shell injection? +`subprocess.run(final_argv, ...)` uses list argv (no shell). Tokens are substituted as raw strings, but no `shell=True`. A malicious `harness.command` in `loop.json` could include `"rm -rf /"` as a literal argv element — but that's a config-trust issue, not a runtime escape. The loop.json is controlled by the human operator who created the loop. ✅ Accepted threat model. + +### A5 — Can the runner be pointed at a different project via `--project` to escape scope? +`cmd_tick` resolves `project_dir` from `args.project` and uses it for `_loop_dir` and `cwd`. If a hostile caller passes `--project /etc`, the runner will look for `.automaton/loops/` under `/etc` — which won't exist — and skip `untracked`. No escape. ✅ Defended. + +### A6 — Verdict score outside [0, 1]? +`parse_verdict` does `float(data.get("score", 0.0))`. A hostile verifier returning `score: 99999` would inflate `score_history`. The score-plateau gate checks "flat or non-increasing" so inflation actually breaks a plateau (good for the attacker — loop continues). No hard cap on score. **Acceptable for v1:** the score is informational; verifier-prompt contract (task 6) will say "score in [0, 1]". Could clamp in `parse_verdict` for safety; noted for v1.1. Not blocking. + +### A7 — Can the OS scheduler fire a tick while the runner is mid-tick? +OS unit fires `automaton-loop-tick.sh` which invokes `loop-runner.py --mode tick`. If the previous tick is still running, two `cmd_tick` instances run concurrently. Both might pass `--check-gate`, both might invoke harness subprocesses, both might write state (atomic last-writer-wins). Result: double-spent tokens for one iteration count increment. **Mitigation:** scheduler interval should exceed tick duration; lock-file in v1.1. Same TOCTOU as A2; same BACKLOG item. + +### A8 — Can a corrupt `loop.json` crash the runner? +`_read_loop_config` returns `None` on JSON parse failure. `cmd_tick` calls `(cfg or {})` for all `.get()` accesses.

Accepted. + +### O4 — `_context_floor_ok` returns `True` if `vram_detect.py` subprocess fails +Best-effort choice: a missing/broken `vram_detect.py` (e.g. on a fresh CI container without the script installed) is treated as "eligible". Correct for portability (the framework shouldn't hard-refuse a tick on a platform where the tool isn't built), but means the 16k floor (D13) can be silently bypassed on misconfigured hosts. **Trade-off accepted; documented in the function's docstring.** If a user wants strict enforcement, they install `vram_detect.py`. No code change. + +### O5 — No upper bound on `outputs/` directory growth +Every tick writes 3 files (implement, verify, orchestrate). Over 100 ticks that's 300 files. Trees on some filesystems (HFS+, ext4 default) degrade past 10k entries per dir. v1 has `max_iterations` to bound this; for daemon mode with `max_iterations=0`, the user is responsible. v1.1 hardening: add `outputs.retention` to `loop.json` (keep last N ticks).

A verifier that returns `{"pass": "false", "score": 0.1}` will be recorded as `pass=True`. Verifier prompts (task 6) must instruct the model to emit JSON booleans. **Minor robustness fix here:** check for string and normalize. Let me note this for task 6 prompt work, but also harden in v1 — `parse_verdict` should coerce `"true"/"false"` strings. I'll leave it for v1.1 since the verifier prompt (task 6) is the actual contract; the prompt will tell the model to emit `true`/`false` as JSON booleans, not strings.

That is correct behavior (humans and ad-hoc agents can still work), but it means a hostile agent could **race the loop runner to claim a task**. Mitigation: loop runner should call a `--claim-loop-task` (not in v1) or set `current_task` atomically before transitioning. **Not a brakes-layer bug** — it's a runner-layer concern (task 3). Note for task 3. + +### A3 — Can `--pause-loop` be used to bypass the worktree drift gate? +No — pausing just stops the scheduler; `.state.loop` remains the source of truth. `--check-gate` still runs all gates; a paused loop's gates return `paused:` (not ok). The runner will not tick. Defended. + +### A4 — Can the agent hand-write `.state.loop` to fake "running"? +Yes — `.state.loop` is a plain JSON file. A fully local adversary with filesystem access can edit it. This is an accepted threat model: the framework assumes the harness is cooperative for state files but enforces via the pre-edit hook (`--can-edit`) for source edits. **`.state.loop` is not in any task's file_scope**, so it's never editable by a loop agent.

Defended. + +### A6 — Can `--approve --loop` be called while the loop is mid-tick? +`--approve` does tmp+rename. If a tick is concurrently writing iteration_count, the approve's write wins and the tick's increment is lost. Window is small (subprocess boundary). Acceptable for v1; the next tick re-reads and re-increments. Not a corruption vector. **Note for v1.1:** file-locking (fcntl) on `.state.loop` would close this race. Add to BACKLOG. + +### A7 — Can `--install-schedule` be pointed at a different project than the loop? +`--install-schedule` uses `_find_project_dir(args.project)` and writes the stub at `loop_path / run-tick.*`. The stub `cd`s into the project root and invokes the runner with the loop name. An attacker could swap the loop_name in the stub after generation, but that's just running an arbitrary loop — not a privilege escalation. Not an attack. + +### A8 — Can the schedule wake the loop after it's halted? +Yes — the OS unit fires `run-tick` on schedule. `run-tick` invokes `loop-runner.py --mode tick --loop NAME`, which **must** call `--check-gate` first and exit 1 if not ok. The runner's contract (task 3) is: gate first, then work. The OS unit itself cannot refuse. So a halted loop's schedule will fire `run-tick`, which will no-op via the runner's gate check.
