From 2658deee94fa38e484c3e6f5dde35b21eb338817 Mon Sep 17 00:00:00 2001 From: drew Date: Sun, 17 May 2026 10:02:53 -0400 Subject: [PATCH] feat(auto-agents): PR State Warmer substrate + supporting infra MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Adds a long-lived sidecar (pr_state_warmer.py) that polls Forgejo's /pulls endpoint every 30s and writes the full PR snapshot to a shared SQLite store, eliminating the dispatcher's per-cycle cold-cache stalls (24-30s rebuilds on flaky cycles) and the silent 50-PR pagination cap on the legacy single-page fetch. Substrate - tools/_pr_state_cache.py — SQLite store with (owner, repo) PK, WAL mode, additive v2→v3 migration (comments_refreshed_updated_at), bounded fcntl.flock migration lock, threading.Lock for per-process init, @_with_reheal decorator (catches OperationalError no-such- table + DatabaseError corruption with file quarantine), atomic TEMP-table chunking for >32k seen-set, _normalize_updated_at to canonicalize Forgejo tz-marker drift - tools/pr_state_warmer.py — poll/upsert/vanish/comments-refresh loop with fcntl.flock singleton (rejects second warmer), bounded comments-refresh cap, persistent deferral via SQL pending query, PermissionError-tolerant lock setup, cold-start log suppression - tools/_pr_classification_cache.py — three-layer fall-through (warmer cache → list cache → live fetch) with staleness gate (PR_STATE_WARMER_STALE_AFTER_S floored at 30s in prod) Comments cache hardening - Bot-filter at write time drops bot status/claim/release/sentinel while preserving **Implementation Attempt** markers (94.6% reduction on bot-heavy PRs like #30's 19k-comment thread) - _normalize_since_cursor strips microsecond precision before building ?since= query (fixes the live-observed Forgejo HTTP 422 bug on PRs #25 + #28); handles uppercase Z, lowercase z, ±HH:MM offsets (including non-zero like +05:30), naive ISO - Lazy migration of legacy null-key by_author entries on _read_cache - _newest_cursor walks tail-back skipping malformed entries Supporting infrastructure (cumulative dmpipeline-v2 work) - Telemetry server: SSE live tail, run-sessions enumeration, cost/token tracking, app.js UI rewrite with collapsible sections - MCP servers (mcp_ci_server, mcp_forgejo_server, mcp_git_server, mcp_handoff_server, mcp_graphify_server) for opencode worker context access - Live log writer (tools/live_log_writer.py) — SSE-streaming dispatcher event log - Tier-dispatcher escalation flow with prompts trimmed for budget - Shared bot-logins resolver (tools/_bot_logins.py) replacing two drift-prone copies - token_usage_audit.py for opencode cost analysis Tests - 2259 passing across 65 changed/new files - New suites: test_pr_state_cache, test_pr_state_warmer, test_pr_state_warmer_integration, test_pr_classification_cache, test_pr_list_cache_backoff, test_mcp_* (5 servers), test_live_log_writer_sse, test_telemetry_run_sessions, test_review_post_ready_label - Test_pr_comments_cache expanded with bot-filter coverage, cursor-normalization regression pins, format-drift, atomicity, failed-comments-not-stamped (silent-data-loss class) - Parametrized @_with_reheal coverage across 7 wrapped APIs - Real fault-inject atomicity test for chunked mark_vanished path via Connection wrapper class - Subprocess-based singleton flock test (cross-process contract) - Event-driven SIGTERM-mid-poll test (no fixed-sleep flake) Architecture notes - Schema v3 migration is additive (ALTER ADD COLUMN); v0/v1 still need destructive rebuild because pre-v2 column shape lacks owner/repo. Cross-process drop-table-ping-pong prevented by the fcntl migration lock + per-process _initialized flag. - Comments-refresh deferral is persistent via comments_refreshed_updated_at column — survives warmer restart, picks up next cycle even if PR didn't change again. Replaces in-memory changed_numbers list. - Rollback path: PR_STATE_WARMER_PREFER=0 bypasses the warmer cache and reverts to live-fetch behavior. PR_STATE_CACHE_DISABLE=1 short-circuits the warmer process at startup.

Each block shows `[state] context` + `full log: ` + a fenced log tail. The failing assertion / lint rule / stack trace lives at the END of each log — read each tail in full before deciding what to fix. When a block shows `_log unavailable_: `, fall back to the `log_url` (open in browser) or call `ci_fetch_pr_failure_logs(pr)` MCP tool (the cache may have warmed since prompt build). - **`## Pre-fetched CI per-check detail`** is the lighter-weight per-check status list (context + state + target_url + description).

So every PR runs at the default slot (`tier-0`) regardless of complexity + — trivial typo fixes consume default-tier compute when `tier-min` would do, + confidently-hard PRs waste a Tier 0 attempt before the label-driven escalation + kicks in. (The model behind each slot is configured in `tiers.yaml` and + propagated by `tools/sync_tier_models.py`; reason in capability, not in model + names — per the [tier-min.md guidance](../../.opencode/agents/tier-min.md).) + +Skills and instructions need **no** action — `dmpipeline` is byte-identical to +or strictly ahead of `final-working` on every shared skill, and `final-working` +has no instruction files at all (§7.3, §7.4). + +Separately, the comparison's §3 also listed ten **dmpipeline-internal +weaknesses** — unrelated to `final-working`, but real. **Phase 5** of this plan +folds in the cheap, well-scoped, high-value subset of those (#5, #7, #8, #10); +the remaining three (#1, #3, #6) are recorded under "Known dmpipeline weaknesses +— deferred" with actionability notes but no task yet. + +## Solution + +Port the four high-value items and the medium-value deterministic checks into +the Python runtime (and, where cheaper, into the worker agent prompts).

If the verdict is "refine," apply the + recommendations and re-review. Loop at most **5 times**; commit only once the + verdict is "commit" (or note the residual concerns if the cap is hit). +- **Test gate:** `pytest tests/auto_agents/` must pass for the touched area + before a task's review loop can return "commit." +- **Flag-gating:** new consequential runtime behavior (G4 early-abort, W5 + post-claim verify, W8 degraded-prompt signal) ships behind an `*_ENABLED` env + flag, **default-off**, per dmpipeline convention. +- **OpenCode restart:** tasks that edit `.opencode/agents/*.md` or model files + (G2, G8-prompt, C3) need an OpenCode server restart to take effect — that + restart is **not** performed without explicit per-turn authorization. +- **Deferred this run:** **W7** (`npx --yes tsx` removal) — deferred pending + confirmation it is needed. **A4** (human-visibility layer) — held pending a + scoping explanation and a go/no-go decision. + +## Scope + +**In scope:** every "bring over" finding from `implementation_comparison.md` — +the §7 deep-content findings G1–G10, the §4 architectural items A1–A7, and the +cross-cutting hygiene items C1–C3.

Confirm that guard covers + *every* Forgejo fetch path (candidate collection, claim, prefetch) and that + there is an idle-cycle PAT re-validation. Port only the gaps. +- **G9** — `grep` shows `_implementer_compliance_apply.py` does **not** call any + PR-body edit endpoint today, so the "omitted body field" footgun may not be + reachable. Confirm whether *any* `tools/` path PATCHes a PR (title/body/labels) + and, if so, audit for full-body re-send. +- **A2** — confirm whether `merge_drive.py` already handles open-dependency PRs + as robustly as `final-working`'s `merge_pr.ts` `--dep error|delete|reverse` + strategies before porting anything. + +--- + +## Phase 1 — Regression + high-value guardrails + +The "do first" set. Small, well-scoped, high leverage. + +### G3 — Restore merge candidate priority ordering + +- **What:** `merge_drive.py::pick_candidates` ([tools/merge_drive.py:737](../../tools/merge_drive.py#L737)) is documented flat FIFO — `"""Pick up to cfg.max_n eligible PRs, oldest-first (FIFO fairness)."""` with `eligible.sort(key=lambda pr: pr.get("created_at") or "")` at [:741](../../tools/merge_drive.py#L741). `pr_is_eligible` ([:647](../../tools/merge_drive.py#L647)) is a boolean gate, not a ranker. `final-working`'s `pr-merge-supervisor.md` worked five priority buckets: `ready_to_merge` → `stale_no_conflicts_approved` → `stale_has_conflicts_approved` → `stale_no_conflicts_not_approved` → `stale_has_conflicts_not_approved`. +- **Change:** add a bucket sort key to `pick_candidates`: rank eligible PRs into the five buckets (the driver already fetches `mergeable`, labels, approval state), with `created_at` as the within-bucket tiebreaker. Keep FIFO fairness *inside* each bucket. +- **Tests:** extend `tests/auto_agents/test_merge_drive.py` — a mixed pool asserts ready-to-merge is picked before a stale-conflict-unapproved PR; within-bucket order stays oldest-first. +- **Effort:** low. **Value:** high (a real regression — the train can burn a cycle rebasing an unapproved conflict PR while a ready PR waits). + +### G2 — Anti-"pre-existing / out-of-scope" CRITICAL rule + +- **What:** `final-working`'s `task-implementor.md` Rule 12 forbids declaring a failing test "blocking / pre-existing / out of scope." `dmpipeline`'s `task-implementor.md` lost it, and its `gate_preflight` guidance ("`unrelated` failures are environmental, do NOT bail") can be *misread* as licensing leaving them unfixed. +- **Change:** add a CRITICAL rule to [.opencode/agents/task-implementor.md](../../.opencode/agents/task-implementor.md), reconciled with preflight: an `unrelated` failure means *do not bail the cycle*, but the worker must still fix it or open a tracked dependency PR — never leave it as "pre-existing." +- **Tests:** `tests/auto_agents/test_implementer_prompt_snapshot.py` snapshot update (the rule is prompt text). +- **Effort:** low (prompt edit). **Value:** high (closes the most common worker cop-out). + +### G1 — Metadata-only work diversion (delegate-or-implement) + +- **What:** `final-working`'s `task-implementor` classifies each item as *code work* vs *metadata-only* before cloning and diverts metadata-only items, with the tie-breaker "when in doubt, classify as code work." `dmpipeline` has no diversion — a missing-label issue still gets a full clone/gate/commit cycle. +- **Change:** add a deterministic pre-classifier in `dispatch_implementer.py` (it already prefetches body/diff/CI/labels via `_implementer_prefetch`). Heuristic: zero failing *code* CI checks + no `REQUEST_CHANGES` review referencing source files + gaps confined to labels/milestone/description → `metadata_only`. Default tie-breaker is "code work" (Python default). +- **Landing — option 1b (full):** since grooming (Phase 3 / G7) is in scope, route `metadata_only` items to the dedicated grooming path rather than a minimal in-worker branch. Sequencing: build G7's grooming module first, then wire G1's classifier to dispatch into it. (Option 1a — a `metadata_only` sentinel field + short no-clone worker branch — is the fallback only if G7 slips.) +- **Tests:** `tests/auto_agents/test_dispatch_implementer.py` — classification table covering pure-label item, label+CI-failure item (→ code work), ambiguous item (→ code work); plus a test that a `metadata_only` classification dispatches to the grooming path. +- **Effort:** medium. **Value:** high (avoids a full tier-0+ cycle for a 2-second label PATCH). **Depends on:** G7 (Phase 3). + +### G4 — Mid-flight worker doom-loop detection + +- **What:** `final-working`'s `worker-health-evaluator.md` inspects a running worker's recent messages for *doom loop* (same tool call 4+×), *retry cascade* (5+ consecutive tool errors), *permanent block*, *permission deadlock*, *empty reasoning loops*. `dmpipeline`'s `watchdog_check.py` is heartbeat-mtime only (confirmed — no message inspection); the only per-worker net is `_opencode_worker.py`'s ~900 s wallclock watchdog, so a worker stuck at minute 2 burns the full budget undiagnosed. +- **Change:** add a soft-threshold probe in `_opencode_worker.py` (watchdog at ~[:1314](../../tools/_opencode_worker.py#L1314), poll loop ~[:1587](../../tools/_opencode_worker.py#L1587)): once a session passes ~30–50 % of `timeout_seconds`, fetch recent messages and run the five pattern checks — **all mechanically computable** (repeated-identical-tool-call counter, consecutive-tool-error counter, no-tool-call-for-N-messages counter), no LLM. On a hit, `POST /abort` early with `error_kind="doom-loop"` / `"retry-cascade"` / etc. instead of an opaque `watchdog-timeout`. The classification reason becomes a telemetry / cycle-archive field. +- **Tests:** new `tests/auto_agents/test_opencode_worker_doomloop.py` (or extend `test_opencode_worker.py`) — message-stream fixtures for each pattern; assert early abort + correct `error_kind`; assert a healthy long session is *not* aborted. +- **Effort:** medium. **Value:** high (saves up to ~15 min wallclock per stuck worker; produces a real failure cause). **Note:** put the five pattern checks in a pure, separately-tested helper (e.g. `_watchdog_helpers.py` or a new `_session_pattern_checks.py`) so `_opencode_worker.py` only wires it. +- **Design constraint (A3 — `session-health-full-util` timing heuristics):** reuse the heuristics the surviving `session-health-full-util.md` agent already encodes so the deterministic checks don't false-positive — a `sleep` command does **not** count as meaningful tool activity; `step_finish.reason == "tool-calls"` means "waiting," **not** "stuck"; "healthy is the default when signals are mixed." The doom-loop / retry-cascade counters must exclude `sleep` calls and the `tool-calls` waiting state before tripping. + +### G11 — Re-enable estimator-driven adaptive tier selection + +- **What:** `final-working`'s implementation flow invokes `estimator-implementation` on every attempt, which can confidently recommend any of Tier -1 / 0 / 1 / 2 (`tier-min` → `tier-2` in current slot naming; historically `qwen-small → kimi` before the 2026-05-15 manifest refactor). `dmpipeline` has the *better* estimator file (no `webfetch`, missing-prefetch guard, capability-descriptor tier table) and the full tier wiring (all four slot agents committed, mapping table generated from `.opencode/models/tiers.yaml`), but **two coordinated bypass layers** keep it dormant on the live path: + 1. **Dispatch-path bypass:** `dispatch_implementer.py` always seeds `start_tier` (defaulting to `0`), and `implementation-worker.md:326-327` defaults `escalation_tier_hint: 0` when missing — `tier-dispatcher.md:141` then SKIPS the estimator whenever a hint is present. + 2. **Estimator self-bypass:** [.opencode/agents/estimator-implementation.md:227](../../.opencode/agents/estimator-implementation.md#L227) — *"CRITICAL: Always use tier 0 when the pull request is new or you have no information about what tier was previously used. Estimation should only be applied on escalation after the first attempt."* This contradicts the same file's role description ("called once per work item on its first attempt") and would force `is_confident: false` even if the dispatch path were fixed. + + Net effect: every PR runs at Tier 0 (`tier-0` slot) on the first attempt. Trivial typo PRs over-allocate the default slot when `tier-min` (Tier -1, the cheapest slot) would do; confidently-hard PRs burn a Tier 0 attempt before label-driven cross-cycle (or in-cycle) escalation hands them to Tier 1+. + +- **Change (three coordinated edits):** + 1. **`dispatch_implementer.py`:** on a true first attempt (no prior `auto/last-attempt-tier-N` label) AND no in-cycle escalation already active, do **not** emit the `escalation_tier_hint` line. The existing label-driven hint path and in-cycle escalation hint path remain as-is — those still drive escalation on retries. + 2. **`implementation-worker.md`:** when the prompt has no `escalation_tier_hint` line, **omit** the line in the `tier-dispatcher` invocation (don't default it to `0`). That triggers `tier-dispatcher`'s estimator path. + 3. **`estimator-implementation.md`:** remove the contradictory CRITICAL rule — *"Always use tier 0 when the pull request is new… Estimation should only be applied on escalation after the first attempt"* (currently at line 232; line number may drift, so locate by content). The estimator returns `is_confident: true` (with `recommended_tier` in `-1`…`2`) or `is_confident: false` (caller defaults to Tier 0) based on actual complexity assessment. + +- **Net behavior:** + - Trivial PRs → Tier -1 (`tier-min`, the cheapest slot). Faster, cheaper. + - Normal/ambiguous PRs → Tier 0 (`tier-0`, the default slot) via `is_confident: false`. Same as today. + - Confidently-hard PRs → Tier 1 (`tier-1`) or Tier 2 (`tier-2`) **upfront**, skipping the wasted Tier 0 attempt. + - All retries → label-driven cross-cycle escalation OR in-cycle escalation (unchanged). + +- **Tests:** `tests/auto_agents/test_dispatch_implementer.py` — four cases: (a) first attempt + no labels → no hint emitted, estimator runs; (b) labeled retry → existing hint behavior, estimator skipped; (c) in-cycle escalation active → existing hint behavior, estimator skipped; (d) `IMPLEMENTER_ESTIMATOR_ENABLED=0` → existing always-Tier-0 behavior preserved. Plus a `test_implementer_prompt_snapshot.py` update for the prompt-shape changes. Estimator file edit covered by `test_estimator-implementation` if such exists, else add a content-rule test that the contradictory CRITICAL rule is absent. + +- **Flag:** `IMPLEMENTER_ESTIMATOR_ENABLED`, default `0` (off), per dmpipeline convention. When off, the existing always-Tier-0 first-attempt behavior is preserved byte-for-byte. + +- **Effort:** medium. **Value:** high — bidirectional savings: trivial PRs run on a cheaper/faster model, hard PRs skip a wasted cycle. The cost is one estimator call per first attempt (~10-30s wallclock on a small model); offset many-fold by even occasional confident recommendations. + +- **Origin:** new finding from the 2026-05-15 review discussion — not a port from `final-working` (its estimator file is materially worse than dmpipeline's, see §7.2). Strictly: this re-enables a capability dmpipeline already has the wiring for but deactivated. **Pairs with:** the existing in-cycle escalation work (`docs/development/implementer-in-cycle-escalation-plan.md`) — both must compose cleanly (the estimator's recommended starting tier becomes the in-cycle escalation loop's Tier 0). + +--- + +## Phase 2 — Deterministic compliance & safety checks + +Medium-value, mostly small. Two are verify-first. + +### G6 — BDD-touched / label-set / milestone compliance checks + +- **What:** `final-working`'s `implementation-supervisor.md` baked an 8-item PR compliance checklist into every worker prompt. `dmpipeline` covers items 1/2/3/6 deterministically (`implementer_validate.py`, `compliance_gaps` in `_implementer_compliance.py`) — *better* than `final-working`. **Items 5/7/8 are absent:** BDD/Behave tests touched when behaviour changed; the specific label set (`State/In Review` + `Priority/*` + `MoSCoW/*` + `Type/*`); milestone = earliest open milestone matching the issue. +- **Change:** + - Add `validate-bdd-touched` to `implementer_validate.py` — flag when the diff touches `src/` but not `features/`. + - Extend `compliance_gaps` in `_implementer_compliance.py` with `pr_label_set_complete` and `pr_milestone_assigned` checks (mechanical — the dispatcher already prefetches labels/milestone). +- **Tests:** extend `tests/auto_agents/test_implementer_validate.py` and `test_implementer_compliance.py`. +- **Effort:** medium. **Value:** medium. + +### G5 — 401/403 hard-stop + idle-cycle PAT recheck *(verify-first)* + +- **What:** `final-working`'s supervisor: a 401/403 from any fetch → do not sleep, report + wait; after 3 idle cycles, re-validate the PAT via `GET /user`. +- **Change:** audit `_dispatch_runtime.py` (the existing guard at [:418](../../tools/_dispatch_runtime.py#L418)) for full coverage; if any Forgejo fetch path can still swallow a 401/403, make it hard-stop. Add a consecutive-idle-cycle counter that re-validates the PAT after N empties. +- **Tests:** `tests/auto_agents/test_dispatch_runtime.py` — stub a 401 on candidate collection → assert hard-stop, not sleep; N idle cycles → assert a `GET /user` probe fires. +- **Effort:** low–medium. **Value:** medium (a dead PAT otherwise spins idle forever). + +### G9 — PR body-deletion footgun *(verify-first)* + +- **What:** `final-working`'s `pr-creator.md`: "always re-send the full body when editing the PR — the Forgejo API deletes the body if the field is omitted." +- **Change:** confirm whether any `tools/` path PATCHes a PR (`grep` shows `_implementer_compliance_apply.py` currently does not). If a PR-edit path exists or is added, ensure it always re-sends the full body; add a regression test. If no such path exists, close as no-op with a note. +- **Tests:** if applicable, a `test_implementer_compliance_apply.py` case asserting the body field is present on every PR PATCH. +- **Effort:** low. **Value:** medium-if-applicable. + +### G8 — Reviewer CI-failure triage heuristic + +- **What:** `final-working`'s `pr-review-worker.md` distinguishes "CI failing with issues introduced by this PR" (→ REQUEST_CHANGES) from "CI issues already known / not introduced" (→ may still APPROVE). `dmpipeline`'s `_review_fetch.py::fetch_ci_check_detail` docstring *references* this intent but no prompt section gives the worker a method, and with `webfetch: deny` the worker can't read the failing logs. +- **Change:** + - **Prompt:** add a "CI failure triage" subsection to [.opencode/agents/pr-review-worker.md](../../.opencode/agents/pr-review-worker.md) — cross-reference each failing check's `context` against changed files; treat non-blocking only when no changed file plausibly maps to it. + - **Optional Python:** have `dispatch_review.py` fetch a truncated log tail per failing check (it has network access; the worker does not) and embed it as a `## Pre-fetched CI failure logs` fence — extends `_review_fetch.py` near [:835](../../tools/_review_fetch.py#L835). +- **Tests:** review-prompt snapshot update; if the log-fetch lands, `test_review_fetch.py` coverage for truncation + redaction. +- **Effort:** low (prompt) / medium (log-fetch). **Value:** medium. + +--- + +## Phase 3 — Grooming capability (optional, larger) + +Only if reintroducing metadata grooming is on the roadmap. Pairs with G1. + +### G7 — Grooming Quality-Analysis label-inference rules + +- **What:** `final-working`'s `grooming-worker.md` has an 11-point checklist with precise deterministic if/then label rules: closed item w/o `State/*` → `State/Completed`(merged) / `Wont Do`; `State/In Review` w/o open PR → revert to `In Progress`; `[AUTO-*]` tracking-issue dedup keeps newest by `created_at`; Priority/Type/MoSCoW/milestone always flow issue→PR never reverse; >7-day stale → comment, don't silently change state. +- **Change:** new `tools/groom_*.py` module — the if/then label logic is pure and belongs in Python, not an LLM prompt. Wire it as either a new `dispatch_groom.py` driver or a work group on an existing driver, and make it the target of G1's metadata-only diversion (option 1b). +- **Exception:** rule #8 (Epic-completeness — auto-creating child issues from scope items) is *not* safe to mechanize — keep it LLM-gated or out of scope. +- **Tests:** new `tests/auto_agents/test_groom_*.py` — table-driven over each label-inference rule. +- **Effort:** high. **Value:** medium (high if grooming is roadmapped — it's a genuine capability gap). + +--- + +## Phase 4 — Observability & hygiene + +Lower urgency; can land independently. + +### A4 — Automation-tracking / human-visibility layer *(DEFERRED — not in this run)* + +> **Deferred (2026-05-14):** go/no-go was reviewed; deferred because dmpipeline's +> observers currently have `:8765` dashboard / terminal access, making A4 largely +> redundant. Trivially addable later if a "watch from Forgejo, no terminal" +> audience emerges. Spec retained below. + +- **What:** `final-working` exposes "what is the fleet doing right now" via Forgejo automation-tracking issues (status issues with monotonic cycle numbers — a gap = a crash; persistent announcement issues). `dmpipeline` has strong *hard* telemetry (SQLite, Phase-4 JSONL, dashboard) but no human-facing Forgejo issue for non-engineers. +- **Change:** a small `tools/` helper that, each cycle, updates a per-driver status issue in Forgejo with a monotonic cycle number (+ last-action summary, current claim, timestamp). Reuses existing cycle bookkeeping. Update-in-place (not replace-per-cycle) to avoid issue-tracker churn. +- **Open questions for the go/no-go:** one combined status issue vs one per driver; which Forgejo identity posts it; whether the monotonic-cycle-gap crash signal is worth the added per-cycle Forgejo write traffic given the existing heartbeat watchdog + `:8765` dashboard. +- **Effort:** medium. **Value:** medium (push-style operator visibility for non-terminal users; crash detection via cycle-number gaps). + +### A2 — Open-dependency merge handling *(verify-first)* + +- **What:** `final-working`'s `merge_pr.ts` handles Forgejo's silent-no-op-on-open-dependencies bug with `--dep error|delete|reverse` and typed `MergeError` codes. +- **Change:** audit `merge_drive.py` for equivalent open-dependency handling; port the dependency-strategy logic only if missing. +- **Effort:** low–medium. **Value:** medium. + +### C2 — Split `dispatch_implementer.py` + +- **What:** `dispatch_implementer.py` is 2,940 lines despite the ~500-line module budget the rest of `tools/` honours; the escalation loop (`_post_session_action_with_escalation`) is a ~350-line nested function. +- **Change:** extract cohesive units (escalation loop, prompt assembly, short-circuit logic) into siblings loaded via `_loader.py`, matching the existing `_implementer_*.py` decomposition. Pure refactor — no behaviour change. +- **Tests:** existing suite must pass unchanged; add module-boundary tests if useful. +- **Effort:** medium. **Value:** medium (maintainability). + +### C3 — Document the model-override-needs-restart footgun + +- **What:** editing a `.opencode/models/*.txt` file does not take effect without an OpenCode server restart; the dispatcher passes the model on `POST /session` purely for observability. This affects the whole escalation premise. +- **Change:** document prominently in `.opencode/models/README.md` and cross-link from `implementer-in-cycle-escalation-plan.md` and `_opencode_worker.py`'s model-resolution docstring. +- **Effort:** trivial. **Value:** medium (operational correctness). + +### A5 — Document reviewer-identity separation as policy + +- **What:** `final-working` runs the review pipeline on a separate `FORGEJO_REVIEWER_*` bot identity (required because branch protection prohibits self-approval). `dmpipeline` already *enforces* this at runtime — `dispatch_review.py::load_config` calls `assert_reviewer_identity` (refuses to start unless the PAT resolves to the expected reviewer account) — but the *convention* isn't written down anywhere as policy. +- **Change:** document the `FORGEJO_REVIEWER_*` convention and the no-self-approval rationale in the `auto-agents-system` skill (and/or `AGENTS.md`), cross-linking the `assert_reviewer_identity` enforcement point. No code change — `dmpipeline` already does the right thing. +- **Effort:** trivial. **Value:** low (consolidates an existing-but-undocumented convention). + +### A7 — Make the generic-supervisor wrapper pattern explicit in docs + +- **What:** `final-working`'s cleanest idea was pipeline-specific behaviour as a thin config wrapper over a generic core (three `*-supervisor.md` wrappers over one generic `supervisor`). `dmpipeline`'s `WorkGroup` dataclass seam in `_dispatch_runtime.py` (`prompt_factory` + `post_session_action` injected per pipeline) already *is* this pattern — it's just not called out as a deliberate design principle anywhere. +- **Change:** add a short "Extensibility: the `WorkGroup` seam" note to a `tools/`-level doc (or the `_dispatch_runtime.py` module docstring) making the parallel explicit, so future pipelines are added the same way. No code change. +- **Effort:** trivial. **Value:** low (conceptual clarity / onboarding). + +### G10 — `git-isolator-util` `identifier:` line + +- **What:** `final-working`'s `git-isolator-util` prompt template carries an `identifier: {work_number}` line `dmpipeline` dropped. +- **Change:** port only if `git-isolator-util` still consumes `identifier` for worktree naming on the fallback path; otherwise skip. +- **Effort:** trivial. **Value:** low (fallback-path only). + +--- + +## Phase 5 — dmpipeline internal hardening + +Unrelated to the `final-working` harvest — these address `dmpipeline`-internal +weaknesses from `implementation_comparison.md` §3. Scoped deliberately to the +**cheap, well-bounded, high-value** subset; the harder weaknesses (#1, #3, #6) +are deferred below. + +### W5 — Post-claim TOCTOU verification in `_dispatch_runtime` + +- **What (§3 #5):** `claim_work_item` documents the GET-then-POST race window. The single-instance `fcntl` lock makes *same-driver* races impossible, but cross-driver / cross-host races remain. `conflict_drive.py` has opt-in post-claim verification; `_dispatch_runtime.dispatch_one` ([tools/_dispatch_runtime.py:745](../../tools/_dispatch_runtime.py#L745)) does not. +- **Change:** after the claim succeeds in `dispatch_one`, re-GET the item's labels; if a *different* `auto/claimed-*` label appeared in the race window, release our claim and skip the item this cycle. Port the verification pattern already proven in `conflict_drive.py`. +- **Tests:** `tests/auto_agents/test_dispatch_runtime.py` — stub a competing claim label appearing between claim and verify → assert our claim is released and the item is skipped; no competing claim → assert normal dispatch. +- **Effort:** low–medium. **Value:** medium (eliminates duplicate-worker dispatch across drivers/hosts). + +### W7 — Remove `npx --yes tsx` from the cycle hot path *(DEFERRED — not in this run)* + +> **Deferred (2026-05-14):** held pending confirmation that this is actually +> needed and a decision on where the dispatcher processes run in production +> (devcontainer vs root Docker image vs bare host) — that determines where +> `tsx` would be pre-installed. Spec retained below for when it is picked up. + +- **What (§3 #7):** `_dispatch_runtime.run_list_script` ([~tools/_dispatch_runtime.py:325](../../tools/_dispatch_runtime.py#L325)) shells out to `npx --yes tsx` every cycle for candidate selection. `--yes` means a cycle can block on — or fail from — a network install of `tsx`, a Node/TS dependency in the hot path of an otherwise pure-Python runtime. +- **Change (cheap tier):** pre-install `tsx` in the runtime image / devcontainer and invoke it directly (or `npx --no-install tsx`), dropping `--yes` so candidate collection can never block on a network install.

Dispatchers READ from +this cache instead of calling Forgejo per cycle. + +v3 (2026-05-17): adds ``comments_refreshed_updated_at`` to drive the +warmer's comments-cache refresh queue from persistent state, not +from the per-cycle ``upsert_prs`` delta. Stores the PR's +``updated_at`` value at the time of the refresh — pending refreshes +are then ``WHERE updated_at != COALESCE(comments_refreshed_updated_at, '')``. +Using the PR's own ``updated_at`` (string equality) rather than a +wall-clock stamp avoids two failure modes: (1) every cycle's +unchanged-upsert advances ``last_seen_at`` which would trigger +spurious refreshes, and (2) Forgejo's ``updated_at`` format and +our wall-clock format have different string-sort semantics. The +change is ADDITIVE — the migration runs ``ALTER TABLE ADD COLUMN`` +rather than DROP/CREATE so a v2 → v3 upgrade preserves data and a +deploy with version skew can co-exist (a v2 reader sees the table +without the new column, which is harmless because v2 readers never +SELECT it). + +Why this design +--------------- + +The dispatcher's per-cycle ``/pulls`` call was both: + +1. **Truncated at 50 PRs** — single page, no pagination. Past 50 open + PRs the 51st+ were silently invisible. +2. **Flaky** — Forgejo's response builds 16 head+base repo+owner + profiles inline (127 KB for 8 PRs). First request after the + server's hot-cache window expires takes 24-30s; dispatcher's + short timeout fires and serves stale. + +The warmer eliminates both problems: pagination is a warmer-side +detail; Forgejo's hot cache stays permanently primed by the 30s +poll cadence (shorter than the ~60-90s cache TTL), so cold rebuilds +collapse to ~1/day. Dispatchers do a local SQLite read (~0ms). + +Storage +------- + +SQLite at ``/tmp/cleveragents-pr-state/state.sqlite3`` (overridable +via ``PR_STATE_CACHE_DIR``). WAL mode so the warmer-writer and +dispatcher-readers can coexist without lock contention. + +Schema:: + + CREATE TABLE pr_state ( + owner TEXT NOT NULL, -- repo owner (e.g. 'drew') + repo TEXT NOT NULL, -- repo name (e.g. 'cleveragents-core') + number INTEGER NOT NULL, -- PR number within (owner, repo) + body_json TEXT NOT NULL, -- full PR object as JSON + head_sha TEXT NOT NULL, + state TEXT NOT NULL, -- 'open' / 'closed' / 'merged' + labels_json TEXT NOT NULL, -- JSON list of label-name strings + updated_at TEXT NOT NULL, -- last-modified at Forgejo + first_seen_at TEXT NOT NULL, -- when the warmer first added the row + last_seen_at TEXT NOT NULL, -- last warmer cycle that found it in /pulls + vanished_at TEXT, -- NULL while open; set when removed from /pulls + PRIMARY KEY (owner, repo, number) + ); + +The ``(owner, repo)`` discriminator prevents a warmer/dispatcher +cfg mismatch (e.g. running tests against the canonical repo while +the prod warmer wrote rows for the fork) from silently serving the +wrong-repo PRs. Every read takes ``(owner, repo)`` and queries +within that scope only. + +Vanish semantics: when a PR disappears from the warmer's enumeration +(closed/merged externally, or the operator deleted it), the row is +NOT immediately deleted — instead ``vanished_at`` is stamped on the +first cycle that misses it AND the row keeps for a grace period +(default 7 days). This lets late-arriving dispatcher cycles still +see the PR's last known state for telemetry/audit purposes. + +Errors +------ + +Operational errors raise :class:`PRStateCacheError`.
