drew 016b348117 feat(controller): grooming gate (Phase 0 + Phase 1 worker-shape dispatch)
Phase 0 (foundation):
- Cause enum (controller_events.cause) for action attribution
- Schema: grooming_decisions audit table; workflows gains
  grooming_evaluated_at + deferred_reason + deferred_at +
  deferred_target_workflow_id; pulls gains touched_files
- audit_comments: CLOSE / DEFER templates + render_comment_template
- forgejo_writes: close_issue + defer_issue 5-step crash-safe protocol
  (fingerprint dedup, error matrix, dry-run)
- patch_pr_state callback in forgejo_http
- grooming_config: 22-env-var frozen-dataclass config + log_effective
- pulls.touched_files cache extension (_pipeline_cache.py schema v8)
- reaper.reap_grooming_decisions audit-retention sweep
- reconciliation RESUME guard (deferred_reason)

Phase 1 (worker-queue shape, 2026-05-25):
- New state: GROOMING. New events: grooming_started, groom_verdict_
  {proceed,defer,close}. 5 new transitions; all invariants still clean
- GroomingInputV1 + GroomingOutputV1 Pydantic contracts
- outcomes._map_grooming_outcome routes verdicts to state-machine events
- prefetch.build_grooming_stage_b_input + list_open_prs callback
- scheduler GROOMING -> grooming_stage_b role
- promote: cfg-gated DISCOVERED -> GROOMING when CONTROLLER_GROOMING_
  ENABLED=true; issues skip grooming
- forgejo_writes decomposed: close_act/defer_act (Forgejo writes only;
  state-machine already transitioned) + close_decide_and_act/
  defer_decide_and_act (Phase 0 callers); _apply_workflow_transition
  is underscore-private
- grooming.py library: tokenization, suspicion scoring (Jaccard +
  weighted overlap), deterministic checks, action -> verdict mapping
- mcp/grooming_builder.py: 14-tool FastMCP server emits GroomingOutputV1
- .opencode/agents/grooming-stage-b.md: duplicate-detection agent
  prompt (claude-haiku-4-5)
- grooming_side_effects.run_grooming_side_effects_tick: per-state tick
  performs Forgejo writes after groom_verdict_{defer,close} fires.
  Filters on event_type='transition' + payload.event (centralizes the
  convention pending Phase 2's latest_transition_event helper)
- GroomingCallbacks frozen dataclass; loop.py + __main__.py wired

Worker role registry (single source of truth):
- worker/roles.py: WORKER_ROLES + WorkerRoleSpec + default_roles_csv
  + output_filename_for. agent_runner.ROLE_TO_MCP_MODULE / ROLE_TO_
  OUTPUT_MODEL derive from it; opencode_session.agent_name_for reads
  it for flat cases; all 6 prompt builders use output_filename_for;
  worker --roles default = default_roles_csv(); launcher script
  derives --roles via shell substitution. Cross-site invariant test
  enforces alignment across 5 sites + opencode.json MCP registry.

Phase 0 silent-bug fix:
- reconciliation.py RESUME guard SELECT now includes deferred_reason
  (was missing since Phase 0; guard was a silent no-op). Tightened
  from getattr to attribute access to fail fast on future omissions.

Tests (1456 total, +91 grooming-specific):
- test_grooming_phase0.py: 34 tests (orchestrator matrix, crash
  recovery, idempotency, dry-run)
- test_grooming_phase1.py: 60 tests (library, contracts, state
  machine, outcomes, scheduler, promote, prefetch, act-variants
  with signature parity, side-effect tick incl. natural-idempotency
  + executed-flag-skip + verdict-mismatch + reconciliation RESUME)
- test_mcp_builders.py TestGroomingBuilder: 29 tests (happy paths
  + 22 validation rules + Pydantic round-trip + master-tick-read-
  path companion)
- test_worker_agent_runner.py TestRoleMaps: cross-role wiring
  alignment + agent-prompt-vs-worker-fallback filename contract +
  inspect.signature equality (close_act/defer_act vs
  close_issue/defer_issue)
- test_state_machine.py: transition count 51 -> 56 +
  events_from_grooming

Live-validated end-to-end on 4 staged sentinel PRs (#55-#58) in
dry_run: agent emits verdicts via MCP, state-machine transitions
fire, side-effect tick writes audit row, deferred_reason gates
reconciliation RESUME correctly.

Deferred refinements + Phase 2 prerequisite (latest_transition_event
helper) tracked in .drew/regressions-plan.md "Phase 1 follow-up
backlog".

drew d3cf710d29 fix(controller): tier-selection calibration — finalize timeout 30s→90s, estimator defaults to tier 1
Two coupled changes responding to the 2026-05-22 batch's tier-0 hit
rate of 0% on PRs the estimator judged "simple", plus three spurious
worker-internal-errors caused by the estimator's MCP-finalize wall
clock exceeding the previous 30s budget.

agent_runner.py — finalize timeout
----------------------------------
`production_agent_runner` previously hardcoded `finalize_timeout_s=30.0`.
On the 8-PR batch the worker recorded three `worker-internal-error`
attempts (PRs 47, 50, 54) all with the same message:

    role='estimator' did not emit canonical output within 30.0s ...

The retries succeeded with estimator self-time of 41.5s, 25.9s, 21.5s —
all within plausible bounds for a multi-subsystem PR (PR 54 needed
41.5s of reasoning + MCP IPC + finalize write). Each spurious timeout
cost ~90s of worker wallclock + a re-dispatch.

New module-level constant `_DEFAULT_FINALIZE_TIMEOUT_S` reads
`CONTROLLER_FINALIZE_TIMEOUT_S` (default 90s), matching the
`CONTROLLER_*_TIMEOUT_S` convention used by `opencode_session.py`.
Operators can tune via `.devcontainer/.env.{fork,prod}`.

estimator-implementation.md — TIER MAP + CALIBRATION
----------------------------------------------------
The estimator was wrong on 4 of 8 PRs in the May-22 batch, all in
the same direction (recommended tier 0, escalated to tier 1).
Three of the four were high-confidence picks — including a PR
described as "4 string constant replacements, isolated scope, no
logic changes" that still got bounced at tier 0.

Three prompt changes:
- TIER MAP rewritten: tier 1 is now the default for non-trivial
  work; tier 0 requires positive evidence the change is mechanical
  (single file, ≤50 LOC, no new logic, no test changes).
- CONFIDENCE RULES "When uncertain, prefer" flipped tier 0 → tier 1.
- New CALIBRATION section bakes in the empirical observation (0/4
  hit rate, why Haiku struggles in this codebase, cost calculus:
  wrong tier-1 < wrong tier-0 by an order of magnitude when measured
  per merged PR).

tiers.yaml — clarify scope
--------------------------
The previous "Used by estimator-implementation.md to make tier
choices model-agnostic" comment on the `capability` field misled
readers into thinking tiers.yaml drove classification. It doesn't —
the estimator agent reads its TIER MAP from its own prompt and
emits an integer; tiers.yaml only answers "for tier-N, which model
runs?". Updated header + field comments to flag this clearly so
future operators don't change descriptors here expecting the
estimator to honor them.

Tests
-----
+ test_default_finalize_timeout_reads_env: covers the env-var
  resolution for `CONTROLLER_FINALIZE_TIMEOUT_S` (default, override,
  float values). Restores the default at the end so subsequent
  tests in the session see the stock constant.

Existing tier-model registry + 27 agent_runner tests pass unchanged.

drew a103a31bbf feat(controller): worker-owned gated push for the implementer
The implementer agent no longer pushes to git — the controller worker
now owns the push: it gates the agent's commits on lint+typecheck and
pushes via a single leased primitive. Closes two production defects:

- Clobber: the pre-fix MCP --force-with-lease leased against a
  freshly-fetched tip, so the lease always passed — an in-flight
  implementer destroyed a commit pushed to the PR branch during its
  run (lost a hand-pushed skip_coverage fix on PR #46).
- Gate-skip: the agent verified only the CI-flagged gate, so a fix for
  one gate shipped fresh violations in another (lint flapped
  pass->fail across CI runs 198->199).

Step 1 — worker_push primitive:
- New git_push.py: one leased push, pinned to the SHA the worker
  started from; classifies pushed / stale_input / diverged /
  infra_error; bounded infra-retry.
- mcp_git_server.push gains expected_sha for a correctly-pinned lease.
- finalize_conflict_resolution migrated onto worker_push.

Step 2 — deterministic gate:
- New gate.py: per-slot nox env-dirs (no venv races), manifest-hash
  staleness keying, lazy warm-up.
- local_ci_gate.sh gains --envdir.

Step 3 — worker-owned gated push:
- New implementer_finalize.py: divergence pre-check -> lint+typecheck
  gate -> ruff auto-fix -> leased push. finalize's outcome is
  authoritative over the agent's emitted outcome.
- agent_runner integrates finalize; salvage no longer pushes.
- outcomes/tick: gate-failed + push-time stale-input caps,
  epoch-scoped; WorkerError carries an output_payload so the gate
  report reaches the next attempt's prompt; prefetch surfaces
  gate-failed attempts.
- The 5 task-implementor prompts drop the agent push step.

Reviewed across 4 adversarial rounds; full controller+MCP suite green
(1379 passed).

drew 8fe98cb5c0 feat(controller): salvage timed-out implementer + cap unbounded prefetch-retry loop
Two reliability fixes from the proactive audit of untouched pipeline
modules (AUDIT-1, AUDIT-2 in .drew/PENDING_FIXES.md).

AUDIT-1 — a timed-out implementer's committed work was never salvaged.
opencode_session maps an OpenCode timeout / transport-error to
WorkerError, which propagated out of production_agent_runner BEFORE the
canonical-output wait + _salvage_implementer_commits ran. A timeout is
the case most likely to have a complete committed fix (agent ran out of
wallclock, not correctness). The session-exception handler now runs the
same salvage the canonical-missing path uses before discarding the
attempt as worker-internal-error.

AUDIT-2 — a persistently failing prefetch() retried every master tick
forever (the T4-4 guard covered only the issue-kind sub-case; same
unbounded-retry class as the run-2 174x estimator loop). The scheduler
now journals each prefetch failure as a controller_events row, counts
failures since the workflow's last transition, and routes the workflow
to STUCK after _PREFETCH_FAILURE_LIMIT (10) failures. The STUCK
transition is rowcount-guarded so the journal never records a
transition the current_state guard rejected.

7 new tests; full controller suite (1169) green.

drew a6ff7da63c fix(controller): recover work lost to plumbing + run-25 reliability fixes
Run-25 surfaced five ways the controller lost or mis-routed correct
implementer work. Each is fixed:

1. Canonical-output salvage (agent_runner.py): when an implementer's
   OpenCode session ends cleanly but emits no V1 output, its commits
   are no longer discarded — they are pushed and a synthetic
   outcome=resolved routes the workflow to AWAITING_CI so CI judges the
   code. Guarded by lost_lock_check so a reaped worker cannot race a
   fresh one on the shared worktree.

2. Preserve committed-but-unpushed work (workspace.py): the pre-reset
   snapshot (auto-scratch/pr-<N>) now captures committed commits ahead
   of the reset target, not just dirty edits — a finished-but-unpushed
   fix survives for the next attempt to adopt.

3. blocked escalates (outcomes.py): an implementer 'blocked' below
   MAX_TIER now escalates to a stronger tier instead of dead-ending at
   STUCK; only 'blocked' AT MAX_TIER STUCKs.

4. Diff-size tier floor (tick.py): the estimator's structured
   recommended_tier can contradict its own reasoning (a 387-file PR
   emitted as tier 0). current_tier is now floored deterministically by
   diff size so a huge PR cannot run on the weakest model.

5. CI log excerpt (prompts.py): the per-gate log excerpt is now
   tail-clipped, not head-clipped — the failure tracebacks live at the
   bottom and were being cut off, leaving the implementer blind.

1121 controller tests pass (+34 new).

drew 0bc734c020 style: ruff format the controller-state-machine branch (288 files)
Applies `ruff format` to the accumulated formatting debt on this branch.
Formatting-only — no behavioral changes. Required for CI/lint's format
gate (`nox -s format -- --check`), which the branch was failing on 288
tracked files that drifted from ruff's canonical style.

In-progress WIP files are intentionally excluded so this commit stays a
clean formatting-only diff.

drew 2ad0958cb7 fix(controller): batch O — trial-2 fix: interpolate real attempt_id into prompts
Trial run-2 surfaced the actual blocker: the response-builder MCPs
shared their module-global ``_STATE`` across OpenCode sessions (they're
registered as ``type: local`` in opencode.json, so OpenCode spawns one
subprocess per OpenCode-server lifetime, not per session). The CA2/PD5
cross-session reset I added in the M-batch keyed on
``identity.attempt_id`` — but the prompt template literally read:

  1. ``estimator_start(attempt_id=..., workflow_id=..., ...)``

The ``...`` were placeholder ellipses, not interpolated. So agents
guessed ``attempt_id=1`` every single time. The cross-session reset
compared ``1 == 1``, decided "same attempt — no reset", and the prior
attempt's ``finalized=True`` persisted forever. Every estimator
session after the first failed with ``"response already finalized;
no further mutations allowed"`` on every ``_set_*`` call → no
finalize → 30s worker timeout → workflow STUCK.

Observed in trial run-2: 2 successes (attempts 1, 2), then 15
consecutive failures (attempts 3–17 across all 6 workflows) before
the pickup_guard would have STUCK every workflow.

Two fixes (defense in depth):

1. **Unconditional reset on _start** in all 5 builders. We can't
   distinguish "agent retry in same session" from "new session reusing
   this MCP" reliably — the observable signature is identical. Just
   reset whenever ``_STATE.started`` is True; ``reset_for_new_attempt``
   logs a WARN if the prior state was in-flight so abandoned attempts
   are still visible to ops. The agent's last ``_start`` always wins.

2. **Interpolate real attempt_id + workflow_id + pr_number + head_sha
   into all 5 prompts' Output contract sections**. The agent_runner
   now injects ``attempt_id`` into ``input_payload`` (matching the
   existing ``workspace_dir`` injection pattern). Each ``build_*_prompt``
   reads ``input_payload.get("attempt_id")`` and bakes the concrete
   value into the MCP-call signature shown to the agent, plus a
   ``PASS THESE EXACT VALUES`` directive.

Also strengthened each prompt's ``_finalize`` line with
``**You MUST call this tool — without it the controller times out.**``
so the agent understands the contract is hard, not optional.

Updated tests:
- ``test_double_start_refused`` → ``test_double_start_resets_silently``:
  pins the new permissive-reset behavior + asserts the WARN log fires.
- ``test_implementer_rejects_intra_session_double_start`` updated for
  same reason; now asserts the second _start succeeds + last-wins
  semantics (used_tier == new tier).
- NEW ``test_prompt_interpolates_real_attempt_id`` parametrized over
  all 5 roles: asserts ``attempt_id=42`` + ``workflow_id=7`` appear
  literally in the rendered prompt AND that ``attempt_id=...`` /
  ``workflow_id=...`` placeholders DO NOT.

Total: 795 → 800 tests, 0 regressions.

The model-override files (.md + .txt) are still in place from the
prior turn — that change is orthogonal to this bug fix; OpenCode
ignores the dispatcher's pass-through per the README, and the actual
generation has been on haiku the whole time. The .md frontmatter
change to sonnet will only take effect on the next OpenCode restart.

drew a4892f8db9 fix(controller): batch N — second-round adversarial review fixes
Round-2 adversarial review on commit 84da77421 confirmed 20+ M-batch
fixes were correct, but surfaced 4 real new issues + missing test
coverage for the gnarliest ones. This commit:

BLOCK-ON-TRIAL fixes:
- CA-R2-C: estimator + summarizer have setter-auto-start (for
  backward compat) that sets _STATE.started=True WITHOUT populating
  identity. The M-batch cross-session reset keyed on identity.attempt_id
  → never triggered for setter-first paths. An explicit _start
  afterwards saw started=True, raised "may only be called once",
  permanently wedging the MCP. Added "identity-less-carryover"
  detection to estimator_start + summarizer_start so they also reset
  in that case. Test: TestSetterThenStartDoesNotRaise (2 cases).
- PD-R2-3: empty FORGEJO_URL silently produced "/{owner}/{repo}.git"
  garbage clone URLs that failed cryptically per attempt. Worker
  startup now fails loudly (exit 2) with a clear error pointing at
  the env var. Test: TestEmptyForgejoUrlFailsStartup.
- PD-R2-7: stale-file unlink permission failure was logged as
  WARNING and proceeded — the poller would then read the stale file
  as if it were fresh attempt output (the very bug CA1 was supposed
  to fix). Hard-raises WorkerError now so the underlying perms/FS
  issue surfaces.
- PD-R2-14: legacy_adapter._clamp_tier(None) silently returned 0 for
  the implementer's `used_tier` field — lying about which tier
  actually ran when the runner has a None-tier bug. Added
  allow_none=False mode that emits a loud WARN. Test: TestUsedTierNoneWarn.

TEST COVERAGE for previously-untested fixes (TE-R2-7..16):
- CA10 credential helper: 2 tests verifying clone URL has no token
  embed AND that clone_if_absent installs `credential.helper` with
  the env-sourced FORGEJO_TOKEN reference in local git config.
- CA6 CI poll role union: test seeds implementer attempt_number=1
  then conflict_resolver attempt_number=2, asserts CI poll picks
  the newer conflict_resolver SHA.
- PD9 outcome='resolved' filter: test seeds a `blocked` implementer
  attempt with head_sha_after set, asserts the poll skips it
  (workflows_waiting=1) instead of false-greening on stale SHA.
- PD16 inline-callback exception handling: 2 tests verifying that a
  RuntimeError from the callback re-raises as
  WorkerError(outcome='worker-internal-error') AND that
  WorkerLostLock passes through unchanged.
- PD10 atomic-write .tmp leftover: pre-creates a garbage .tmp from a
  prior crashed write, runs successful finalize, asserts the .tmp is
  gone after os.replace and the final content is correct.
- PD11 V1-passthrough wallclock: explicit assertion that the agent's
  wallclock_seconds survives passthrough even when the runner passes
  a different measured wallclock.
- CA9 dataclasses.replace regression bound: asserts WorkerConfig
  field set is preserved across replace; a future-added field that's
  not handled by the CLI replace call will fail this test loudly.
- CA4 adapter telemetry positive case: paired with the existing
  negative (V1-passthrough doesn't log) test.

POLISH (CA-R2-D): adapter telemetry log promoted from INFO to
WARNING so the migration-progress signal survives production
log-level tuning (default INFO often raised to WARNING).

REGRESSION FIX: 2 existing entry_points tests broke when PD-R2-3
added FORGEJO_URL validation. Added FORGEJO_URL to those fixtures.

Total: 781 → 795 tests, 0 failures.

CONFIRMED-CLEAN by round-2 reviewers (the M-batch fixes that actually
landed correctly): CA1, CA2 (implementer/reviewer/conflict_resolver),
CA3, CA6, CA7, CA8, CA9, CA12, PD1, PD3, PD4, PD7, PD8, PD9, PD10,
PD13, PD14, PD15, PD16, PD22.

DEFERRED (not block-on-trial): test fidelity improvements
(TE-R2-1, -2 specific assertion strengthening), CA-R2-E (reviewer
same-attempt-id reuse), TE-R2-11 (CA7 lost-lock short-circuit
direct test), TE-R2-15 (cross-session concurrent race — probably
unreachable in single-MCP-per-OpenCode-process model).

drew 84da774212 fix(controller): batch M — post-Phase-1m adversarial review fixes
Three rounds of adversarial review (Chief Architect / Principal Dev /
Senior Test Engineer) on commits 3ca794be7..db12f45ac surfaced ~35
issues. This commit addresses 25+ across criticals, highs, and
mediums, and adds 40 new tests covering the changes plus key gaps the
review identified.

CRITICALS (M1):
- CA1: stale {role}_output.json from a prior attempt on the same
  per-PR workspace was readable as "fresh" output of the new attempt.
  agent_runner now unlinks the MCP-canonical path AND every fallback
  path BEFORE the session runs.
- CA2/PD5: opencode.json-registered MCP subprocesses persist across
  OpenCode sessions, but BuilderState was module-singleton. Added
  reset_for_new_attempt() + cross-session detection (compare
  identity.attempt_id) to every *_start; force-resets with WARN if
  prior attempt was interrupted (timeout / lost lock).
- PD3: inline-JSON callback could overwrite an MCP-written canonical
  V1 file with adapted-from-prose garbage. Callback now inspects
  existing files and skips when V1 is already present.
- PD4: FORGEJO_URL = .rstrip("/api/v1") is a character-set strip —
  catastrophic for hosts whose path contains /v1 in the middle.
  Replaced with explicit endswith()-based suffix strip.
- CA10: clone URL embedded $FORGEJO_TOKEN, persisted into
  .git/config where any agent could cat it. Token now sourced via
  local credential.helper at clone-time, URL kept clean.
- CA12: state.finalized was set BEFORE the file write, so disk-full
  / OSError left the agent unable to retry finalize. Reordered.

HIGHS (M2):
- CA3/PD12: output_path validation (NUL-byte rejection, must be
  absolute, parent-not-file check) in finalize_and_emit.
- CA6: ci_status_poll SELECT only considered implementer attempts;
  conflict_resolver also pushes commits. SQL now unions both roles.
- PD9: ci_status_poll could advance on a stale "resolved" SHA from a
  blocked attempt (whose head_sha_after == head_sha_before). Added
  outcome='resolved' filter.
- CA8: cancelled/stale CI states mapped to ci_red_retry_same_tier,
  burning pickup_count on healthy PRs. Both now wait (treated as
  operator/system action, not failure). timed_out stays red.
- TE9: unknown Forgejo CI states now WARN-log instead of silently
  being treated as pending — operators see new state strings.
- PD8: ci_status_poll event_type strings standardized to match the
  state-machine event names (ci_green / ci_red_retry_same_tier)
  instead of legacy ci-green / ci-red.
- CA7: inline-JSON callback now checks lost_lock_check BEFORE write
  so a file isn't staged after lock loss.
- PD10: atomic .tmp + os.replace writes in both MCP finalize and
  inline callback so the poller never sees a half-written file.
- PD16: inline_output_callback exceptions now re-raise as WorkerError
  instead of being silently logged (root cause was buried 30s later
  in a canonical-output timeout).
- CA9: WorkerConfig manual rebuild on --max-concurrent/--poll-interval
  silently dropped new fields. Use dataclasses.replace, matching
  round-4 P5 fix in master/__main__.py.

MEDIUMS (M3) — legacy_adapter quality upgrades:
- PD1: unrecognized confidence values now WARN instead of silently
  defaulting to "medium" — surfaces agent prompt drift.
- PD2: estimator recommended_tier clamped to {0,1,2} so an out-of-
  range int doesn't bypass the adapter's whole purpose.
- PD7: reviewer blocking_issues list-of-strings coerced into the
  list-of-BlockingIssue-dict shape strict_parse requires.
- PD13: conflict_resolver prompt defaults tier=1 + warns instead of
  raising; the scheduler always sets it but defends against drift.
- PD14: summarizer summary < 50 chars padded with a clear marker so
  strict_parse accepts it (and the truncation is visible).
- PD15: implementer blockers capped at 4096 chars each so a buggy
  agent can't blow up audit log / DB column.
- PD17: launch script accepts either FORGEJO_TOKEN or GITEA_TOKEN
  with a clear error if both are unset.
- PD22: conflict_resolver adapter accepts singular commit_sha
  fallback, matching implementer.
- CA4: every adapter invocation logs role + payload key fingerprint
  so operators can measure agent-migration progress.
- estimator + summarizer now have explicit _start tools (the prompts
  already referenced them; previously absent → first call would fail).

TESTS (M4) — added 40 tests in test_post_review_fixes.py:
- Cross-session MCP state reset (implementer + reviewer + estimator
  + summarizer; intra-session double-start still rejected).
- finalize_and_emit output_path precedence (arg > env > stdout),
  parent-dir creation, rejection of relative/NUL paths, failed-write
  leaves state retryable.
- legacy_adapter quality: tier clamping, blocker cap, non-string
  commit warning, blocking_issues string coercion, conflict_resolver
  full roundtrip + non-resolved head clearing, summarizer padding,
  confidence warning, V1-passthrough no-log.
- opencode.json registration parity: every MCP the prompts name is
  registered with the correct module path.
- Per-role prompts mention {role}_output.json (canonical poller path)
  + the "DO NOT emit chat-JSON" directive.
- FORGEJO_URL suffix-strip parametrized table.
- agent_runner stale-file cleanup: prior-attempt file is unlinked
  before a new session can read it as phantom output.

Also updated 2 pre-existing tests for the CA8 / PD8 / PD13 behavior
changes (cancelled→wait, event_type renaming, conflict_resolver
default-tier warning).

Total: 741 → 781 tests, 0 regressions.

DEFERRED (M5 follow-up — non-trial-blocking):
- CA5: head_sha verification via git cat-file (requires subprocess).
- CA11: discovery_interval_s wall-time cadence (vs iteration count).

drew bcc59d38af fix(controller): trial-path output channel — harvest inline JSON + legacy-shape adapter
Trial run-1 surfaced the real failure mode: the existing agent
prompts emit their result as a single JSON object in the FINAL
assistant message (the legacy dispatch_implementer/dispatch_review
contract). They DON'T call the controller's response-builder MCPs
(not registered in opencode.json) and they DON'T write a file. The
worker's canonical-output poller timed out every attempt.

Fix (two pieces):

1. INLINE JSON HARVEST
   ``_opencode_worker.run_session_blocking`` already extracts the
   last JSON object from the agent's final response into
   ``SessionResult.parsed_json``. The controller's opencode_session
   adapter was ignoring it.
   - ``opencode_session.py:run_opencode_session`` now accepts an
     ``inline_output_callback`` kwarg. After the session completes,
     if parsed_json is set, the callback fires.
   - ``agent_runner.py`` provides the callback: writes the parsed
     JSON to the canonical-output path so the existing poller picks
     it up uniformly with the MCP + file-write channels.

2. LEGACY → V1 SHAPE ADAPTER (``worker/legacy_adapter.py``)
   The legacy JSON shape doesn't match V1 contracts:
   - estimator: legacy {recommended_tier, is_confident, reasoning}
     vs V1 {output_version, recommended_tier, is_metadata_only,
     confidence, reasoning, wallclock_seconds}
   - implementer: legacy {outcome: resolved|unresolved, ...} vs V1
     {outcome: resolved|rebase-failed|blocked|noop|competence-failure,
     commit_shas, blockers, used_tier, ...}
   - reviewer: legacy {verdict, ...} vs V1 {output_version, verdict,
     blocking_issues, suggested_next_action, ...}

   ``adapt_to_v1(role, payload, tier, wallclock_seconds)`` normalizes
   each role's legacy shape into the corresponding V1 dict:
   - adds ``output_version="V1"``
   - maps outcome enums (``unresolved`` → ``blocked``)
   - synthesizes missing required fields with sensible defaults
   - coerces singular commit_sha → list[commit_shas]
   - converts legacy is_confident bool → confidence string

   Already-V1 payloads pass through unchanged. The agent_runner
   wraps the inline_output_callback to run the adapter before
   writing to the canonical path.

Tests (+12 in test_legacy_adapter.py):
- Each role's adapt: legacy in, V1-validating-via-strict_parse out
- Already-V1 passthrough
- Outcome enum mappings + invalid-outcome fallback
- Singular commit_sha normalization
- Non-dict / unknown-role passthrough (lets strict_parse raise)

Total: 738 controller tests pass (+12 net), 0 regressions.

Long-term: update agent prompts to emit V1 directly, register the
MCPs in opencode.json. For the trial, this adapter lets the existing
agents flow through the new controller unchanged.

drew f57d9f9478 fix(controller): batch L — round-4 trial-blockers (A1, P1, P3, P4, P5, T5)
Round-4 adversarial review found 5 trial-blockers + 1 silent-debt
item the post-round-3 deep pass missed. All fixed.

A1 — pre-clone the workspace so the agent has a worktree to operate on
``worker/__main__.py``: the agent_runner closure now constructs a
``PerPRWorkspace`` from input_payload.owner/repo/pr_number + the
FORGEJO_URL+FORGEJO_TOKEN env vars. Pre-flight:
- ``workspace.ensure_present()`` creates the dir skeleton.
- ``workspace.clone_if_absent()`` clones the repo into
  ``{workspace_dir}/worktree/`` if not already present (idempotent).
- ``workspace.fetch_and_validate(head_sha, head_ref)`` refreshes +
  verifies the workspace is at the expected head. ``StaleInputError``
  → ``WorkerError(outcome='stale-input')`` so the master re-prefetches
  without burning a pickup. ``RuntimeError`` → ``worker-internal-error``.
Previously the agent saw an empty workspace_dir + had no repo.

P1 — partial-write defense in the canonical-output poller
``worker/agent_runner.py:_wait_for_canonical_output`` now polls each
path with a two-pass quiescence check (size stable + content parses
as JSON) before returning. Partial writes (agent crashed mid-flush)
are skipped + the polling loop continues. The previous
``f.read().strip()`` returned partial JSON which then tripped
``ContractValidationError`` → ``worker-internal-error`` with no
record of WHICH path; now logs source path on every read.

P3 — TOCTOU defense in promote_discovered
``master/promote.py``: the UPDATE now filters
``current_state='DISCOVERED'``. If a concurrent reconciliation
moved the row off DISCOVERED between SELECT and UPDATE, rowcount=0
+ we skip the event-row write. No duplicate audit entry; no
overwriting a pause-by-label-removal.

P4 — explicit tuple-length validation in reconciliation_args + discovery_args
``master/loop.py``: previously a 6-tuple silently fell into the
``else`` 4-tuple unpack, raised ValueError("too many values"), got
swallowed by the per-iter ``except Exception``, and reconciliation
silently died forever. Now: ``elif n == 4`` + ``else: raise TypeError``.
The TypeError still hits the per-iter except (so the loop doesn't
crash) but ``logger.exception`` surfaces the actionable message in
journald. Operator sees "reconciliation_args must be a 4- or 5-tuple;
got length 6" instead of zero indication.

P5 — --tick-interval CLI flag preserves other config fields
``master/__main__.py``: replaced the manual ``MasterConfig(...)``
rebuild (which dropped reconciliation/ci_poll/discovery intervals)
with ``dataclasses.replace(cfg_loop, tick_interval_s=args.tick_interval)``.
Operators who pass --tick-interval no longer silently revert the
other intervals to defaults.

T5 — scheduler._commit_escalation uses safe_json_dumps
``master/scheduler.py``: the escalation event row's payload was the
only call site that bypassed safe_json_dumps. Now consistent — a
future contributor adding a datetime/Decimal field won't trip raw
json.dumps at runtime.

Tests (+4 net):
- ``test_worker_agent_runner.py::test_partial_write_not_read``: pins
  P1 (truncated fallback file + valid MCP output → MCP wins).
- ``test_master_promote.py::test_toctou_state_change_between_select_and_update``:
  pins P3 (steal state via monkey-patch → no double-promotion, no
  extra event row).
- ``test_master_loop.py::test_reconciliation_args_wrong_length_logs_not_silent``:
  pins P4 (6-tuple → logged error, not silent forever).
- ``test_entry_points.py::test_tick_interval_flag_preserves_other_cfg_fields``:
  pins P5 (env-set non-default intervals survive --tick-interval).

Total: 711 controller tests pass (+4 net), 0 regressions.

drew 0c9e8fdd69 fix(controller): trial-path output channel — fallback file-write for unwired MCP layer
RB7 (newly discovered) — response-builder MCPs are NEVER REACHABLE
from the OpenCode agent:

The controller spawns the per-attempt response-builder MCP via
``python -m tools.controller.mcp.{role}_builder`` with stdin=PIPE
+ CONTROLLER_CANONICAL_OUTPUT_PATH set. But:
- ``.opencode/opencode.json`` does NOT register the controller MCPs.
- OpenCode only knows about MCPs it sees in opencode.json (graphify,
  ci, forgejo, git, handoff).
- The OpenCode agent has NO transport to call
  ``implementer_finalize`` because OpenCode doesn't see the MCP.
- The controller's spawned MCP subprocess sits waiting for JSON-RPC
  on stdin that no one sends.
- The agent does work, the session ends, the canonical-output-file
  is empty, agent_runner times out with WorkerError.

This would have been the single biggest blocker to running an actual
Phase 2 trial. The MCP layer is structurally complete but not
plumbed into OpenCode — pivoting requires either registering them
in opencode.json (which doesn't support per-attempt env injection)
OR adding a fallback channel.

Fix (trial-path):
- ``worker/prompts.py``: each role's output-contract section now
  documents BOTH the PREFERRED MCP call AND a FALLBACK direct
  file-write to ``{workspace_dir}/{role}_output.json``. The agent
  can pick either; once the MCP layer is wired (Phase 1m) it'll
  naturally prefer the MCP.
- ``worker/agent_runner.py:_wait_for_canonical_output``: now polls
  the MCP-canonical path AND a list of ``fallback_paths``. Call
  site adds ``{workspace_dir}/{role}_output.json`` to fallback
  paths. First non-empty wins.

Tests (+2):
- ``test_fallback_file_picked_up_when_mcp_silent``: agent writes
  only the fallback file (no MCP drive); runner reads it.
- ``test_first_nonempty_output_wins``: documents the
  poll-both-channels semantic.

Documented Phase-1m work:
- Register controller MCPs in ``.opencode/opencode.json``
- Solve per-attempt env injection (the canonical_output_path is
  per-attempt; opencode.json env is static — needs a request_id
  arg on finalize() OR a workspace-relative output convention)

Until that's done, the trial uses the fallback file-write path.

Total: 705 controller tests pass (+2 net), 0 regressions.

drew febb352618 fix(controller): pipeline run-blockers — promoter, scheduler, owner/repo, workspace_dir patch
Round-3 deep pass identified four issues that would have prevented an
actual end-to-end pipeline run:

RB1 — DISCOVERED → ANALYZING never fired in production:
The state machine defines (DISCOVERED, discovery_picked_up) →
ANALYZING but NO production code fires the event. Workflows
created by discovery would sit in DISCOVERED forever.

Fix:
- New ``master/promote.py``: ``run_promote_discovered_tick`` scans
  for DISCOVERED workflows + fires ``discovery_picked_up`` via
  apply_event (state-machine invariants stay enforced) + emits a
  ``discovery-promoted`` controller_events row per transition.
- Composes with the master loop's other ticks; runs every iteration
  (cheap — typically 0-1 row).

RB2 — scheduler.schedule_next_attempts never called from master loop:
The scheduler was exported by the master package but never invoked.
It creates the ``workflow_attempts`` rows that workers dequeue —
without it, workers would have nothing to pick up.

Fix:
- ``master/loop.py`` now accepts a ``prefetch: PrefetchCallback``
  kwarg. When provided, the loop runs promote_discovered + scheduler
  every iteration after tick/reaper/reconciliation.
- ``MasterTickReport`` gains ``promote_discovered`` and ``scheduler``
  optional fields so on_iteration callbacks see both.
- ``master/__main__.py`` builds a ``PrefetchDataCallbacks`` from the
  Forgejo callback bundle and constructs the production
  ``make_prefetch_callback(engine, callbacks)`` — wires through to
  the loop's new prefetch kwarg.

RB3 — owner / repo missing from V1 input contracts:
The implementer / reviewer / estimator / conflict-resolver V1 inputs
had pr_number but not owner/repo. The OpenCode agent would have
had no way to know which Forgejo repo to clone — it would have had
to derive owner/repo from process env, coupling the worker to a
single repo.

Fix:
- ``contracts/v1.py``: added ``owner: str`` and ``repo: str``
  (min_length=1) to ImplementerInputV1, ReviewerInputV1,
  EstimatorInputV1, ConflictResolverInputV1.
- ``master/prefetch.py``: builders populate owner/repo from the
  Workflow row (already known at prefetch time).
- Existing test fixtures in ``test_contracts_v1.py`` updated.

RB4 — input_payload.workspace_dir placeholder reached the agent:
Prefetch wrote ``workspace_dir = "<worker-injected>"`` as a
placeholder; the worker never patched it before invoking the
OpenCode session. The prompt builder rendered the literal
placeholder string into the agent's prompt — the agent had no idea
where to clone.

Fix:
- ``worker/agent_runner.py``: patches input_payload.workspace_dir
  with the real path immediately before calling run_opencode_session.
  Uses a shallow copy so the caller's dict isn't side-effected.
- ``worker/__main__.py``: workspace_dir naming convention is now
  ``pr-{owner}-{repo}-{pr_number}`` (matches workspace.py's
  PerPRWorkspace convention) so the janitor's pr-* glob + the
  agent's expected workspace location agree. Falls back to
  ``pr-attempt-{N}`` for legacy input_payloads missing owner/repo.

Tests:
- ``test_master_promote.py`` (NEW, +7 tests):
  - empty DB no-op
  - single workflow promoted
  - multiple promoted in one tick
  - only DISCOVERED targeted (non-DISCOVERED untouched)
  - controller_events row emitted with correct shape
  - idempotent after first promotion
  - LoopIntegration end-to-end: DISCOVERED → ANALYZING → pending
    estimator attempt visible in workflow_attempts (pins the entire
    previously-broken pipeline from discovery to enqueue)

Total: 703 controller tests pass (+7 net), 0 regressions.

Without these four fixes, the pipeline would have looked alive in
unit tests but produced zero work in a real deployment.

drew 147e3403c1 fix(controller): batch G — show-stoppers from round-2 review (N1–N4)
Four items the round-2 adversarial review flagged as ship-blockers.

N1 — PID-reuse defense is now WIRED in production:
Round 1's batch D shipped ``subprocess_starttime`` in the sidecar +
janitor checks against it, but NO production code wrote sidecars.
The defense was unwired; tests passed against a code path that
production never invoked.

Fix:
- ``worker/agent_runner.py`` accepts ``workspace_dir`` and
  ``opencode_server_url`` kwargs. When ``workspace_dir`` is set, it
  writes a sidecar (``{workspace_dir}/worker.session``) immediately
  after MCP spawn capturing the real PID + starttime from
  ``/proc/{pid}/stat`` field 22. Removes it on attempt completion.
- ``worker/__main__.py`` builds the per-attempt workspace dir
  (``{workspace_root}/pr-attempt-{N}/``) and threads it through the
  agent_runner closure with the OpenCode URL. The naming convention
  is picked up by the janitor's ``pr-*`` glob; when per-PR shared
  workspaces ship (Phase 1k++ follow-up), it changes to
  ``pr-{owner}-{repo}-{N}``.
- Test: ``TestSidecarWiring`` (+2 tests) verifies the sidecar appears
  during the attempt, carries the right PID + starttime + instance,
  and is cleaned up post-attempt.

N2 — AWAITING_CI escape event firing is now WIRED in production:
Round 1's batch D shipped ``ci_polling_exhausted`` /
``ci_flake_retries_exhausted`` in TRANSITIONS, but NO production code
emitted them. Workflows could still hang in AWAITING_CI forever.

Fix:
- New ``master/ci_poll.py``: ``run_ci_poll_exhaustion_tick`` scans
  workflows whose ``entered_state_at`` is older than
  ``CONTROLLER_AWAITING_CI_TIMEOUT_S`` (default 7200s) and fires
  ``ci_polling_exhausted`` via ``apply_event`` → STUCK + emits a
  ``ci_poll_exhausted`` controller_events row with the threshold
  payload.
- ``master/loop.py`` integrates the new tick on its own cadence
  (``ci_poll_exhaustion_interval_s`` env, default 300s). Composes
  with the existing master loop. ``MasterTickReport`` gains
  ``ci_poll_exhaustion: CIPollExhaustionReport | None``.
- Tests: ``test_master_ci_poll.py`` (+7 tests) — happy path, fresh
  workflow stays untouched, only AWAITING_CI is targeted (other
  long-lived non-terminal states ignored), event row shape pinned,
  default threshold matches the documented 2h, end-to-end loop
  integration (master_main_loop drives the exhaustion +
  workflow → STUCK without operator intervention).
- Dialect-portable SQL (Postgres interval, SQLite julianday).
- Handles SQLite returning TIMESTAMP as str from text() queries
  (no .isoformat() on str).

N3 — externally-merged/closed PRs now win over label removal:
Round-1's PAUSE-on-label-removed shipped, but reconciliation
checked the label gate BEFORE checking merged/closed. Operators
removing the opt-in label on an already-merged PR would PAUSE the
workflow forever — never transitioning to MERGED.

Fix:
- ``master/reconciliation.py:_reconcile_one`` re-ordered:
  1. Check terminal-state mappings (merged/closed) FIRST — apply
     immediately if they fire.
  2. THEN the opt-in label gate (pause/resume).
  3. Fall through to "consistent" otherwise.
- Tests: ``test_externally_merged_takes_priority_over_label_removal``
  + ``test_externally_closed_takes_priority_over_label_removal``
  pin the contract. Both seed an IMPLEMENTING workflow + Forgejo
  reporting "merged/closed AND no opt-in label" → workflow
  transitions to MERGED/ABANDONED (not PAUSED) + pre_pause_state
  stays None.

N4 — graceful handling of empty env vars:
``int(os.environ.get("CONTROLLER_FORGEJO_REQUEST_TIMEOUT_S", "30"))``
crashes with non-actionable ``int('') ValueError`` if the operator
sets the env to empty/whitespace (common when sourcing a partially-
edited /etc/cleveragents/master.env file).

Fix:
- ``master/forgejo_cfg.py:_env_int(name, default)`` — empty or
  whitespace-only values fall back to the documented default; only
  non-numeric values still raise (with a clear message naming the
  variable).
- Tests: ``test_empty_env_value_falls_back_to_default`` +
  ``test_whitespace_only_env_falls_back`` + updated
  ``test_malformed_env_raises_value_error`` to match the new
  "not a valid integer" wording.

Total: 660 controller tests pass (+13 net), 0 regressions.

drew 23a014e402 feat(controller): Phase 1c-3 — production agent_runner (real MCP subprocess)
The production seam that connects the controller's runner to actual
LLM execution. Per-attempt MCP subprocess spawn + OpenCode session
drive + canonical JSON read + strict-parse → output dict.

tools/controller/worker/agent_runner.py:

- production_agent_runner(): the function tested production wires
  into run_one_attempt's agent_runner param. Per-attempt lifecycle:
  1. Map role → matching MCP module + V1 output contract.
  2. mkstemp a canonical-output path; spawn `python -m {mcp_module}`
     subprocess with CONTROLLER_CANONICAL_OUTPUT_PATH set in env.
  3. Call injected run_opencode_session (tests use JSON-RPC stdin
     driver; production wires _opencode_worker.run_session_blocking).
  4. Wait for the MCP's finalize_and_emit to write the canonical
     JSON to the tempfile.
  5. Strict-parse against the role's V1 output model.
  6. SIGTERM/grace/SIGKILL the MCP + unlink the tempfile in finally.

- ROLE_TO_MCP_MODULE / ROLE_TO_OUTPUT_MODEL: explicit per-role
  dispatch tables. Covers all 5 worker roles.

- Error classification per the WorkerError outcome enum:
  - unknown role → ValueError (master bug; not a worker outcome)
  - session raises generic Exception → WorkerError(worker-internal-error)
  - session raises WorkerLostLock → propagated unchanged
  - lost_lock_check returns True after session → WorkerLostLock
  - MCP didn't emit canonical output within timeout → WorkerError(
    worker-internal-error)
  - MCP emitted JSON that fails strict-parse → WorkerError(
    contract-violation; per v9 status='failed' policy maps to
    workflow STUCK)

tools/controller/mcp/_builder_base.py:

- finalize_and_emit() now writes to CONTROLLER_CANONICAL_OUTPUT_PATH
  if set (production subprocess path) or stdout if not (direct-call
  test path; capsys captures). Decouples canonical output from the
  FastMCP JSON-RPC stdout transport — they would otherwise collide
  in the subprocess (both writing to the same stream).
- Atomic file write: open + write + fsync + close.
- Existing test_mcp_builders.py (capsys-based) still passes with the
  fallback path; new test_worker_agent_runner.py exercises the
  file-based subprocess path with real MCPs.

10 new tests in test_worker_agent_runner.py:
- End-to-end with real MCP subprocesses (implementer-resolved,
  reviewer-approve, estimator-tier-recommendation)
- Error paths: unknown role (ValueError), session raises (wrapped
  as WorkerError), session raises WorkerLostLock (propagated),
  lost_lock_check returns True post-session (raises WorkerLostLock),
  no finalize → finalize_timeout → WorkerError
- Role-map sanity: every role has both an MCP module and output model

Total: 376 controller tests; full auto_agents suite 2738 pass.

This commit completes the v1 boundary — the controller now has the
complete stack from V1 contracts through MCP response builders, DB
schema, worker dequeue/heartbeat/runner/workspace, master state
machine + tick + reaper + pickup guard + scheduler + discovery +
Forgejo writes + MERGING + HTTP adapter, AND a production
agent_runner that wires it all to real OpenCode + MCP subprocess
spawning. Phase 1d-3+ enhancements (real OpenCode session wiring
in run_opencode_session) and Phase 2+ migration steps remain.
