From a739553c8f6f327a074f9e16e500618e32880444 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 10 Jul 2026 00:29:12 +0000 Subject: [PATCH 01/43] phase 1 1.1: fix effective-cwd git probing and fail-closed worktree fold-back ClaudeCodeLauncher._git_rev_parse/_git_diff_files were hardcoded to config.working_directory, ignoring cwd_override. For a Wave 1.3 worktree-isolated dispatch this meant pre/post HEAD capture always inspected the parent repo, so a real commit made inside the worktree was invisible: commit_hash/files_changed came back empty even though the agent committed, and the executor's "no commit -> clean up" path then deleted the worktree, silently discarding the work. Thread the launch's effective cwd (cwd_override when set, else config.working_directory) through pre-launch HEAD capture, post-launch HEAD capture, and diff/file discovery so all git inspection for a launch targets the same directory as the subprocess itself. Add a defense-in-depth fail-closed guard in WorktreeManager, independent of what the launcher reports: - fold_back() now verifies (WorktreeProvenanceError) that a reported commit_hash actually exists in the worktree and is not an ancestor of (or equal to) base_sha before folding/deleting anything. - A new _verify_safe_to_discard() re-derives the worktree's own HEAD and dirty status before the "no commit reported" cleanup path is allowed to permanently delete it. executor.py wires both into record_step_result's worktree lifecycle handling: on failure the worktree is left intact and the step is marked failed with a precise WorktreeProvenanceError instead of being folded or discarded. Regression tests added under tests/test_claude_launcher.py (effective-cwd git probing) and tests/test_worktree_manager.py (provenance guard).

Confirmed this test fails against the pre-1.1 launcher (commit_hash comes back empty) and passes against current code, asserting the parent repo receives exactly that commit and the worktree is only removed after the fold succeeds. Also adds TestUnverifiableProvenanceFailsClosed: a "successful" step (status=complete) reporting a commit_hash that cannot be verified inside its own worktree must fail closed via the real (unmocked) WorktreeManager._assert_commit_provenance() guard -- step marked failed, worktree retained on disk, handle kept in step_worktrees, parent branch unchanged. Note (documented in-file, out of scope for this test-only step): while building the positive regression, discovered that WorktreeManager.fold_back()'s hardcoded default "rebase" strategy always fails with git's "refusing to fetch into branch ... checked out" error for any real worktree commit, because WorktreeManager.create() leaves the branch checked out via `git switch -c`. This is independent of the bd-1.1 fix and is masked in the existing suite only because the executor-level fold-back success tests (bd-def9, bd-a735) mock WorktreeManager instead of using real git. The new positive test works around it by pinning the fold *strategy* to fast-forward (matching every other real-git WorktreeManager test in the suite) without mocking any git call -- flagging this for a follow-up Phase 1 fix.

A fold failure during resume therefore looked like a successful resume to every caller: the record showed resolved, and nothing downstream (straggler sweep, gc_stale) would know the worktree still held un-folded developer commits, leaving it eligible for later reclaim -- permanent, silent data loss for exactly the commits a developer takeover exists to rescue. Fold now runs BEFORE the record is marked resolved; on any fold failure the record stays active, the worktree is retained on disk, and resume_from_takeover returns False so the operator knows to retry. On success the now-stale worktree handle is dropped from step_worktrees so later lifecycle code doesn't mistake it for one still needing fold/cleanup. Same audit of record_step_result()'s worktree lifecycle block found the inline try/except around fold_back() and _verify_safe_to_discard() only caught the two *modeled* exception types (WorktreeProvenanceError, WorktreeFoldError); any other exception (e.g. the git binary vanishing mid-run) escaped to the outer catch-all, which logs a warning and leaves `result.status` at whatever the caller passed in (typically "complete") -- claiming success without ever confirming the fold, or the safe-to-discard check, actually completed. Both paths now fail closed on any exception, not just the modeled ones. Regression coverage added under tests/integration/test_worktree_isolation.py (real git, no mocks of the git calls themselves): a fold failure during resume_from_takeover leaves the record active and the developer's commit on disk; an unmodeled exception from fold_back()/_verify_safe_to_discard() during record_step_result() fails the step closed instead of silently recording "complete".

This was masked in the existing suite because every real-git fold test pinned strategy="none" or explicit "rebase"-expects-a-conflict scenarios, never exercising the default path end-to-end; it was flagged but explicitly left out of scope by the 1.2 test-authoring step. This one was NOT data-loss (the fetch failure meant fold_back always raised WorktreeFoldError before touching anything, so the worktree was correctly retained) but it meant no dispatched step's work could ever actually land in the parent branch via the default path, which undermines the same "restore delivery trust" goal this phase exists for -- and, per 1.2's note, fixing just the fetch guard (e.g. with --update-head-ok) was verified BY HAND to trade that safe failure for real data loss: the rebase strategy's 3-argument `git rebase --onto` form checks out its target ref into whatever repository it runs in, which detaches HEAD and overwrites the working directory of the canonical repo -- the live project checkout in normal in-place operation -- even with the fetch fixed. That path is left alone and clearly documented as known-broken but fail-safe, reachable only via an explicit strategy="rebase". Instead, fold_back() now defaults to "merge", which needed two changes to be both correct and safe: (1) merge the commit by SHA directly instead of fetching by branch name -- worktrees of one repository already share a single object database, so no fetch is needed or attempted, sidestepping the "checked out" refusal entirely; (2) fail closed (WorktreeFoldError) if the canonical repo's currently checked-out branch isn't handle.base_branch, since `git merge` always merges into whatever is checked out -- without this guard a mismatch would silently attribute the worktree's commit to the wrong branch. Verified with real git that a successful merge fold also leaves the canonical repo's own working directory in sync (unlike the "none" fast-forward strategy's raw update-ref, which does not). Regression coverage added under tests/test_worktree_manager.py: the default strategy now lands a real worktree commit in the parent branch (confirmed to fail against the pre-fix "rebase" default), and refuses to fold when the canonical repo has switched off base_branch. This also fixes tests/test_wave5_integration.py::TestResumeReronsGateAndPasses, which was previously passing only because the swallowed-exception defect fixed in the prior commit hid this same fold failure -- it now passes for the right reason.

A parent-repo commit made after worktree creation (e.g. a sibling fold advancing main) passed the guard, 'folded' as a no-op ('Already up to date'), and the success-path cleanup then deleted the worktree containing the agent's real, unfolded commit — silent worktree loss. The guard now also requires the commit to be reachable from the worktree's own HEAD, and fails closed when git cannot answer (merge-base/rev-parse errors). 2. _verify_safe_to_discard silently skipped both probes when git returned nonzero (broken/pruned .git linkage), letting the caller delete an uninspectable worktree that could still hold real work. Ambiguous state now raises WorktreeProvenanceError and retains. Regression tests for both in tests/test_worktree_manager.py.

Authoritative owners + +| Component | Owns | Does **not** own | +|---|---|---| +| `ExecutionEngine` (`core/engine/executor.py`) | The single writable copy of `ExecutionState`; all status transitions; task-level and phase-level event emission (`task.*`, `phase.*`, `gate.passed`/`gate.failed`); plan amendment; trace lifecycle. | Process lifecycle (PID files, signals); how/whether an agent subprocess is actually launched; human-facing decision routing. | +| `TaskWorker` (`core/runtime/worker.py`) | The async dispatch loop for **one** task: turning `DISPATCH` actions into concurrent agent launches via `StepScheduler`/`AgentLauncher`, running programmatic gates as subprocesses, and routing human-required gates/approvals to `DecisionManager` (or auto-approving when none is configured). Step-level event emission (`step.*`, `gate.pre_check`). | Persisted state — every mutation goes back through the `ExecutionDriver` methods on the engine it wraps. Process supervision (that's `WorkerSupervisor`). | +| `WorkerSupervisor` (`core/runtime/supervisor.py`) | Process lifecycle for daemon mode: PID file + `flock`, log rotation, SIGTERM/SIGINT drain, `pause_worker`/`resume_worker`/`cancel_worker` (OS signals), `daemon-status.json` snapshots, `recover_dispatched_steps()` after a crash. | State transitions — it constructs a `TaskWorker`/`ExecutionEngine` pair and gets out of the way. | +| `DecisionManager` (`core/runtime/decisions.py`) | The file-based human-decision queue used by async surfaces (daemon `TaskWorker`, interactive `BatonRunner`): `DecisionRequest`/`DecisionResolution` JSON + Markdown sidecars under `/decisions/`, and `human_decision_needed`/`human_decision_resolved` events. | The execution status itself — resolving a decision only unblocks the poll loop in `TaskWorker._handle_gate`/`_handle_approval`, which then calls back into the engine's `record_gate_result`/`record_approval_result`. | +| State storage (`core/storage/` + `core/engine/persistence.py::StatePersistence`) | Durable read/write of `ExecutionState`, keyed by `task_id`, with a SQLite-primary / JSON-file-fallback strategy and reconciliation on divergence (see `ExecutionEngine.resume()`). | Deciding *when* to persist — the engine calls `_save_execution()` after every mutating call; storage never persists speculatively. | +| Event emission (`core/events/bus.py` + `core/events/events.py`) | Typed builders for every documented topic (`task.*`, `phase.*`, `step.*`, `gate.*`, `human_decision_*`, `approval_*`, `budget_exceeded`, `plan_amended`, `team_member_completed`). | Delivery guarantees beyond in-process pub/sub — SSE and webhook fan-out are downstream consumers (`api/routes/pmo.py::stream_pmo_events`, `api/webhooks/dispatcher.py`), not part of this contract. | +| REST API / PMO (`api/routes/pmo.py`, `api/routes/decisions.py`) | Launching new executions (`POST /pmo/execute/{card_id}`, by shelling out to `baton execute run`), process-level pause/resume/cancel, and a decision inbox UI (`GET/POST /decisions*`) that is a thin wrapper over `DecisionManager`. | The state machine itself. The API never mutates `ExecutionState` directly; every route either spawns a CLI subprocess, signals a PID, or delegates to `DecisionManager`. | + +**Rule:** any new code path that needs to change execution status must go +through an `ExecutionEngine`/`ExecutionDriver` method. Direct writes to +`state.status` outside `models/execution.py` are already blocked by +`tests/static/test_no_direct_status_writes.py`; this document is the process +contract that lint enforces mechanically. + +--- + +## 4. Idempotency semantics + +| Operation | Idempotent? | Mechanism | +|---|---|---| +| `ExecutionEngine.start(plan)` on a `task_id` that already has a **non-terminal** persisted execution | **No — by design, it is refused, not silently repeated.** `baton execute run` / `baton execute start` resolve the active task first (`--task-id` → `BATON_TASK_ID` → SQLite active-task pointer → `active-task-id.txt`) and treat any status in `{running, pending, approval_pending, feedback_pending, gate_pending, gate_failed, budget_exceeded}` as *resume, don't restart* (`_RESUMABLE_STATUSES` in `execute.py`). A terminal status (`complete`/`failed`/`cancelled`) raises a user-facing error instead of silently overwriting history. | +| `ExecutionEngine.next_action()` / `next_actions()` called repeatedly with no new results recorded | **Yes.** Steps already in `dispatched_step_ids` are excluded from re-dispatch; the same `DISPATCH`/`GATE`/`APPROVAL` action is returned until a result is recorded. | +| `record_step_result()` called twice for the same `step_id` | **Not idempotent — second call is a bug in the caller.** The engine does not currently de-duplicate by `step_id`; a duplicate `record` call appends a second `StepResult`. Both `TaskWorker` and the CLI loop guarantee single-call-per-dispatch by construction (a step is only in the dispatch set once), but there is no engine-side guard. **Gap — see §7.1.** | +| `record_gate_result()` on a phase whose gate has already passed | **Not idempotent** in the same sense — a second `pass` is a no-op-ish re-advance (harmless because `advance_phase()` is itself idempotent once the phase pointer has moved), but a second call after a `fail` retries the gate-retry counter. Callers should not call this more than once per gate evaluation. | +| `DecisionManager.resolve()` on an already-resolved request | **Yes.** Returns `False` without mutating anything (`req.status != "pending"` guard). The API route (`POST /decisions/{id}/resolve`) surfaces this as `409` if the second caller raced past the `get()` check, or `400` if `get()` already saw `resolved`. | +| `ExecutionEngine.resume()` called on an already-terminal task | **Yes.** Returns the same `COMPLETE`/`FAILED` action every time; does not re-run anything. | +| `WorkerSupervisor.pause_worker()` / `resume_worker()` called twice in a row | **Yes at the OS level** (a second `SIGSTOP` to an already-stopped process, or `SIGCONT` to an already-running one, is a no-op), **but not observable in `ExecutionState`** — see §6. | +| `POST /pmo/execute/{card_id}` called twice for the same card | **No.** The route only checks `card.column == "queued"`; it does not check for an already-running worker PID for that `task_id`. Calling it twice launches two `baton execute run` subprocesses against the same `task_id`. Both subprocesses hit the same active-task resolution + `_RESUMABLE_STATUSES` guard in `_handle_run`, so the second process will *not* restart the plan, but the two processes will race on `next_action()`/`record_step_result()` with no cross-process lock beyond the SQLite OCC retry (`_save_execution_with_occ_retry`). **Gap — see §7.2.** | + +--- + +## 5. Restart semantics + +"Restart" here means: the process driving execution dies (crash, `SIGKILL`, +container restart, CLI process exits between commands) and a **new** process +picks the same `task_id` back up. + +1. **State is durable at every transition boundary**, not just at pause + points. `ExecutionEngine._save_execution()` runs after `start()`, + `mark_dispatched()`, every `record_*` call, `record_gate_result()`, + `record_approval_result()`, and `complete()`. There is no separate + "checkpoint" concept — the persisted `ExecutionState` *is* the checkpoint, + always current as of the last completed engine call. +2. **The one blind spot is mid-dispatch.** If a step was marked `dispatched` + (§ stage 1) but the process died before `record_step_result()` (§ stage 2) + ran, the step is stuck `dispatched` on disk with no agent actually + running. Recovery is explicit, not automatic: + - `WorkerSupervisor.start(resume=True)` calls + `ExecutionEngine.recover_dispatched_steps()` before resuming, which + clears `dispatched`-status step results back to re-dispatchable + (verified by `tests/test_daemon.py::TestRecoverDispatchedSteps`). + - `baton execute run` / `baton execute resume` do **not** currently call + `recover_dispatched_steps()` — a step left `dispatched` by a killed CLI + process stays stuck until an operator notices. **Gap — see §7.3.** +3. **Restart uses `resume()`, never `start()`.** `ExecutionEngine.resume()` is + the one restart entry point implemented by all four surfaces: + - CLI: `baton execute resume` calls it directly; `baton execute run` calls + `next_action()` on an already-`_RESUMABLE_STATUSES` task, which is + equivalent (both load from disk and reattach the trace). + - Daemon: `WorkerSupervisor.start(resume=True)` → `engine.resume()`. + - Top-level `baton run --resume`: `ExecutionEngine()` (no `plan=`) → + `engine.start()` is skipped, `TaskWorker.run()` calls `next_action()` + immediately, which again loads from disk. + - API: does not call `resume()` itself; it launches a **new** + `baton execute run` subprocess, which performs the same active-task + resolution as the plain CLI path above. +4. **Reconciliation on split brain.** When both a SQLite backend and a file + backend hold state for the same `task_id` (possible if a previous write + partially failed), `resume()` compares per-step statuses and promotes + whichever backend is more advanced (`_reconcile_states`). This is the + mechanism that makes "restart" safe across the SQLite/file dual-write + design without a distributed lock. + +--- + +## 6. The pause-and-resume contract (as it exists today) + +This is the part of the lifecycle that is **not yet uniform**, and the task +that produced this document calls it out explicitly, so it gets its own +section rather than being folded into §4/§5. + +There are, today, **two unrelated things called "pause"**: + +1. **Process-level pause** (`WorkerSupervisor.pause_worker`/`resume_worker`, + surfaced at `POST /pmo/execute/{card_id}/pause`|`/resume`). This sends + `SIGSTOP`/`SIGCONT` to the daemon worker's OS process. It freezes the + process's scheduler slot; it does **not** write anything to + `ExecutionState`. A paused worker's persisted status is whatever it was + at the last completed engine call before the signal arrived (per §5.1), + and it stays exactly that until the process is resumed. Publishes + `task.paused`/`task.resumed` events directly via `Event.create(...)` in + `api/routes/pmo.py`, *not* through a typed builder in `core/events/events.py` + (every other task-level event has one). +2. **A `"paused"` status value** already exists in `ExecutionState` and is + wired into the state-handler dispatch table + (`executor.py`: `"paused": AwaitingApprovalState()`), but **nothing in the + codebase ever sets it.** It is reserved, not implemented — grep confirms + the only two writers of `status = "paused-takeover"` (developer takeover, + Wave 5.1) exist, but no code path assigns the bare `"paused"` string. + +**Why this still counts as "durable" today:** because of §5.1, the *durable* +unit is not "pause" — it is "the last completed step/gate/approval". A +worker that is `SIGSTOP`-frozen has, by construction, already persisted +everything up to that point; `SIGCONT` (or a fresh process calling +`resume()`) picks up exactly there. So the pause-and-resume contract holds +**as an emergent property of restart semantics**, not because pause is a +first-class state. That is a real gap for observability (a paused execution +reports `status: "running"` everywhere — PMO board, `baton daemon status`, +`baton execute status` — with no signal that it is actually frozen) and for +any surface that does not have OS-level process control (the CLI action-loop +surface has no pause primitive at all; an orchestrator agent driving `baton +execute next` step by step simply... doesn't call `next` again). + +**Recommendation for the implementation step that follows this document** +(explicitly out of scope here): promote pause to a first-class, +engine-owned transition — +`ExecutionEngine.pause(reason: str) -> None` sets `status = "paused"` via a +new `ExecutionState.transition_to_paused()` (coupled-field write, per the +I1/I2/I9 discipline in `core/engine/CLAUDE.md`), and +`ExecutionEngine.resume()` already handles any non-terminal status, so no +change is needed there. `WorkerSupervisor.pause_worker`/`resume_worker` +would call `engine.pause()`/rely on `next_action()`'s normal resume path +*before* sending the OS signal, so the persisted state and the OS process +state can never disagree, and every surface (not just daemon+PMO) gains a +pause primitive. `task.paused`/`task.resumed` should move to typed builders +in `core/events/events.py` alongside the rest of the task-level events. + +--- + +## 7. Known gaps (compensating controls, not fixes — tracked here for the next step) + +### 7.1 `record_step_result()` has no duplicate-call guard +No engine-side idempotency check exists for calling `record_step_result()` +twice with the same `step_id`. Compensating control: both `TaskWorker` and +the CLI loop only call `record_step_result()` once per dispatch by +construction (a step leaves the dispatchable set the instant it is marked +`dispatched`). Recommendation: add a guard that rejects (or upgrades to a +warning + no-op) a `record_step_result()` call for a `step_id` that already +has a terminal (`complete`/`failed`) `StepResult`. + +### 7.2 `POST /pmo/execute/{card_id}` has no PID-collision guard +The route checks `card.column == "queued"` but not whether a worker is +already running for that `task_id`. Compensating control: the SQLite OCC +retry (`_save_execution_with_occ_retry`) prevents silent data loss on a +concurrent write race, but two live subprocesses double the resource cost +and produce confusing duplicate agent dispatches until one of them loses the +race. Recommendation: check `/executions/{card_id}/worker.pid` +for a live PID before spawning, mirroring the daemon's own single-instance +check in `cli/commands/execution/daemon.py`. + +### 7.3 `baton execute run`/`baton execute resume` don't call `recover_dispatched_steps()` +Only the daemon's `WorkerSupervisor.start(resume=True)` path clears stuck +`dispatched` steps before resuming. A CLI process killed mid-dispatch leaves +that step stuck until an operator runs the daemon path or manually +intervenes.

charset=UTF-8 Content-Transfer-Encoding: 8bit `baton run` (run.py) independently constructed its own ExecutionEngine + TaskWorker + BatonRunner stack -- a second, divergent implementation of the autonomous-loop contract that `baton execute run` (_handle_run in execute.py) already implements, per the §7.4 compatibility plan in docs/internal/execution-runtime-contract.md. That duplicate called ExecutionEngine.start(plan, task_id=...), a signature the engine has never had, so any `baton run` invocation that started a fresh plan (including --dry-run) crashed with TypeError. handler() now translates the unchanged `baton run` CLI surface onto _handle_run instead of retaining a second state machine, so CLI, daemon, and PMO drive the exact same active-task resolution and resumable/ terminal status guard. --max-parallel is accepted for backward compatibility but warns that it has no effect on the canonical sequential runner; --resume is accepted but redundant since the canonical runner always resumes automatically. Adds an optional --max-steps flag (new, additive). Regression tests pin: the CLI surface is unchanged, handler() delegates to _handle_run rather than constructing its own engine/worker, and `baton run --dry-run` completes end-to-end without the TypeError. --- agent_baton/cli/commands/execution/run.py | 138 ++++++++-------- tests/cli/test_run_delegates.py | 189 ++++++++++++++++++++++ 2 files changed, 257 insertions(+), 70 deletions(-) create mode 100644 tests/cli/test_run_delegates.py diff --git a/agent_baton/cli/commands/execution/run.py b/agent_baton/cli/commands/execution/run.py index 537a4c18..675e9148 100644 --- a/agent_baton/cli/commands/execution/run.py +++ b/agent_baton/cli/commands/execution/run.py @@ -1,28 +1,33 @@ """``baton run`` -- autonomously drive an orchestrated execution in the foreground. -This module implements the interactive, autonomous runner.

Previously neither call site passed one, so every human-required GATE/APPROVAL silently hit TaskWorker's "no decision manager configured" auto-approve fallback -- the daemon auto-approved everything merely because dependency injection was omitted, not by design. - TaskWorker gains _handle_feedback/_handle_interact, wired into the execution loop. FEEDBACK and INTERACT actions previously had no handling at all in the async loop, so a plan reaching either busy- looped on next_action() forever. Both now route through the DecisionManager (auto-selecting a fallback answer only when no manager is configured, mirroring GATE/APPROVAL's existing contract, which an existing test pins down and this change does not weaken). Deterministic decision IDs (core/runtime/decisions.py): - deterministic_decision_id()/parse_decision_id() replace the random UUIDs DecisionRequest.create() mints for GATE/APPROVAL/FEEDBACK/ INTERACT requests raised by TaskWorker and the headless CLI runner. A stable ID keyed on (task_id, kind, parts) lets every surface -- CLI re-invocations, daemon restarts, the REST API -- converge on the same pending request instead of creating duplicates, and lets a caller recover which task/phase/step a resolved decision was about without a new structured field on DecisionRequest. PMO paused-task resume path (cli/commands/execution/execute.py): - _run_loop's APPROVAL/FEEDBACK/INTERACT handling under a non-TTY stdin (the headless `baton execute run` subprocess POST /pmo/execute/{card_id} launches) now records a durable DecisionManager request before pausing, instead of leaving the pause implicit in the execution's own status. FEEDBACK/INTERACT previously had no handling in this loop either -- they spun to max_steps and aborted with a misleading "ABORTED" exit(1), indistinguishable from a genuine failure. If the same decision was already resolved by the time this code re-evaluates the action (e.g. a prior invocation paused, and the REST API resolved it since), it is applied directly and execution continues in this same process. TTY behaviour is unchanged for APPROVAL and newly added for FEEDBACK/ INTERACT so `baton execute run` in an interactive terminal no longer busy-loops on either action type. Idempotent decision + atomic resume (api/routes/decisions.py, api/routes/pmo.py): - POST /decisions/{request_id}/resolve now parses a deterministic request_id back into (task_id, kind, parts) and applies the resolution directly to the execution engine via apply_decision_resolution() -- previously resolving a decision only flipped the DecisionManager's on-disk status and published an event that only a live TaskWorker poll loop would ever notice, which is never the case for a headless `baton execute run` subprocess that already exited after recording the pending decision. It then calls resume_task_headless(), which is idempotent: it checks the execution's worker.pid liveness before spawning a new headless runner, so a retried resolve never launches two processes racing on the same task. Legacy random-UUID request_ids (already-resolved decisions predating this change, and gate_escalation requests which are intentionally left non-deterministic) parse to None and are skipped gracefully, not treated as an error. - New GET/POST /pmo/execute/{card_id}/decisions[/{request_id}/resolve] endpoints mirror the generic /decisions API but resolve the card's own project root per-request (via _resolve_worker_context), because the generic API is bound to a single team_context_root at server startup and cannot see a per-card project root on a multi-project PMO board -- the same reason /pmo/gates/pending and /pmo/gates/{task_id}/approve already exist as PMO-scoped counterparts of engine calls. Regression tests cover: supervisor/daemon DecisionManager injection (review gates are no longer auto-approved), TaskWorker FEEDBACK/INTERACT routing (with and without a manager), deterministic ID round-tripping, apply_decision_resolution idempotency (a second apply after a live worker already applied it returns False, not an error), resume_task_headless's worker.pid liveness guard, the headless APPROVAL/FEEDBACK/INTERACT pause-then-resume contract in _run_loop (including duplicate-pause de-duplication), and both the generic and PMO-scoped resolve endpoints applying + resuming exactly once. --- agent_baton/api/routes/decisions.py | 55 +++- agent_baton/api/routes/pmo.py | 174 ++++++++++ agent_baton/cli/commands/execution/daemon.py | 15 + agent_baton/cli/commands/execution/execute.py | 302 ++++++++++++++++-- agent_baton/core/runtime/decisions.py | 193 +++++++++++ agent_baton/core/runtime/supervisor.py | 16 + agent_baton/core/runtime/worker.py | 187 +++++++++-- tests/cli/test_execute_run_pause_decisions.py | 256 +++++++++++++++ tests/test_api_decisions.py | 159 +++++++++ tests/test_api_pmo_decisions.py | 296 +++++++++++++++++ tests/test_daemon.py | 211 ++++++++++++ tests/test_decisions.py | 171 +++++++++- 12 files changed, 1982 insertions(+), 53 deletions(-) create mode 100644 tests/cli/test_execute_run_pause_decisions.py create mode 100644 tests/test_api_pmo_decisions.py diff --git a/agent_baton/api/routes/decisions.py b/agent_baton/api/routes/decisions.py index a8486eeb..b971890b 100644 --- a/agent_baton/api/routes/decisions.py +++ b/agent_baton/api/routes/decisions.py @@ -17,7 +17,12 @@ DecisionResponse, ResolveResponse, ) -from agent_baton.core.runtime.decisions import DecisionManager +from agent_baton.core.runtime.decisions import ( + DecisionManager, + apply_decision_resolution, + parse_decision_id, + resume_task_headless, +) router = APIRouter() @@ -189,7 +194,10 @@ async def resolve_decision( decision_manager: Injected ``DecisionManager`` singleton.

Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 10 Jul 2026 03:45:08 +0000 Subject: [PATCH 10/43] phase 2 2.3: add cross-surface execution-lifecycle regression suite Adds tests that chain multiple stages of docs/internal/execution-runtime- contract.md's lifecycle together, driving real entry points end-to-end and asserting persisted execution/decision state before and after each transition rather than only exit codes: - tests/test_execute_run.py: TestCanonicalAndCompatibilityDryRunParity -- drives both `baton execute run` (canonical) and `baton run` (the compatibility shim) through the real resume-vs-restart guard and asserts they reach identical persisted state. - tests/cli/test_execute_run_resume.py: TestNonTtyApprovalPauseSurvivesRestartAndCompletesOnce -- a non-TTY approval prompt pauses durably across repeated process boundaries without duplicating the decision request, is answered through the DecisionManager (the same object the REST API and PMO inbox delegate to), and completes exactly once; a further invocation refuses to restart the terminal task. - tests/test_daemon.py: TestDaemonRestartWithPendingDecision -- a worker crash while a review-gate decision is pending is followed by a fresh engine+worker pair (mirroring WorkerSupervisor.start(resume=True)) that reuses the same deterministic decision request instead of duplicating it, and drives the task to COMPLETE exactly once after resolution. - tests/test_api_pmo_gates.py: TestPmoExecuteToPauseToApiApproveToResumeToComplete -- exercises the real PMO pause/resume endpoints against a genuinely signalled worker process (proving OS-level pause never mutates ExecutionState), then the decisions-resolve endpoint's apply + headless-resume path driven inline through the canonical runner to a real COMPLETE; plus a duplicate- approval-submission companion test. - tests/test_api_decisions.py: TestDuplicateApprovalSubmissionAgainstEngine -- a duplicate approval submission against a real engine-backed deterministic decision is rejected before it can re-apply to the engine or respawn a headless resume, and the human.decision_resolved event fires exactly once. Sanity-checked two of the new tests against injected regressions (removing the API's duplicate-resolve guard; de-deterministic decision request ids) to confirm they fail against defective behavior, not just vacuously pass.

Claude Date: Fri, 10 Jul 2026 04:03:47 +0000 Subject: [PATCH 11/43] phase 2 review: scope interact decision IDs to the turn so one answer resumes exactly once The deterministic interact decision ID was keyed on (task, step) only, but an interactive step re-presents the same step_id on every turn. Turn 2 therefore matched turn 1's already-resolved decision and both TaskWorker._handle_interact and the headless _run_loop replayed the same human input on every subsequent turn without ever asking the human again. Include the engine-provided interact_turn in the ID: crash-resume at the same turn still converges on one request, while each new turn records a fresh pending decision.

Wire it into ScopeMapBuilder (scope.py): workstream allowed_paths are now normalized and, when no step supplies an explicit path, derived deterministically instead of a single blind fallback to charter.likely_repo_areas. A workstream whose steps are all intentionally read-only is left empty on purpose. New optional project_root/strict/diagnostics parameters on build() are additive (existing 2-arg callers are unaffected). Wire it into ManagerModePlanner (planner.py): a new strict_scope constructor flag (default False, preserving all existing callers) turns ambiguous write scope into a raised ScopeContractError before any sidecar is written; contradictory scope (allowed/blocked collision) always raises. Every nontrivial step's built ScopeContract is now passed through _apply_scope_contract_policy, which strips an intentionally-read-only step's contract back to its own explicit paths (fixing ScopeContractBuilder's naive `step.allowed_paths or workstream.allowed_paths` fallback silently handing review steps a workstream's write scope) and records missing/contradictory findings on ManagerArtifacts.warnings regardless of strict_scope. Regression tests: tests/engine/planning/test_scope_contract.py (new, 60 cases covering normalization, overlap, generated-path policy, derivation tiers, diagnostics) plus new cases in tests/manager/test_scope_map.py and tests/manager/test_manager_mode_planner.py covering strict-mode raising, diagnostic recording, path normalization of explicit paths, and read-only steps never inheriting workstream write scope. All pre-existing tests in both files, plus the full manager/, engine/planning/, e2e manager-mode, and CLI manager-mode/dry-run suites, pass unchanged.

TaskWorker wires this in for every DISPATCH action; unconfigured callers see zero behavior change. - ExecutionEngine.record_step_result now independently recomputes a worktree step's real diff (base_sha -> HEAD, ignoring any caller-reported files_changed/commit_hash) for manager-mode steps with a scope contract, via manager_scope_signal.{independent_worktree_diff, derive_scope_expansion_from_diff}. An out-of-contract diff forces the step to "failed" (so it can never be folded back) and files a durable ManagerDecision backed by persisted evidence (ManagerArtifactPaths.scope_evidence). - New core/manager/scope_amendment.py + ExecutionEngine. resolve_scope_expansion() resolve that decision: reject leaves the failed step and retained worktree untouched; approve durably widens the scope-contract sidecars (atomic os.replace writes) before -- and only before -- the plan's allowed_paths is mutated and the step is requeued for retry.

Fix a real bypass in independent_worktree_diff() (the independent post-diff verifier): git status --porcelain C-quotes any path with a space or other "unusual" byte (e.g. "foo bar.py"), and the naive line-slicing parse kept the literal quote characters as part of the path. For an allow-list contract this only produced a false-positive (fails closed); for a blocked-paths-only contract (no allowed_paths to fall back on) it failed OPEN -- a quoted path silently matched neither side, so a real change inside a blocked directory was reported clean. Switched every git invocation to the NUL-delimited -z form and rewrote the porcelain-v1 parser to consume the paired ORIG_PATH field on rename/copy records instead of splitting on " -> " text. - Fix a real bypass in the launcher's PreToolUse bash guard: it only string-matched $CLAUDE_TOOL_INPUT_FILE_PATH against the allowed/blocked regex, so a symlink created mid-session inside an allowed directory (app/link -> /etc) let a later write "through" it (app/link/passwd) pass the string check even though the real destination was outside the repository. The guard now canonicalizes the write's real destination (readlink -f, falling back to realpath -m) against the subprocess cwd before the allowed/blocked check, and rejects anything that resolves outside the repo/worktree root outright. - Added adversarial regression coverage across the scope-enforcement surface: empty scope, blocked-over-allowed precedence (including cross-sibling-step and nested-nesting cases), absolute paths, dot-dot traversal, symlink escape (real bash-subprocess drive, not a mock), rename/delete, generated-file explicit-vs-inferred handling, untracked files (including git's whole-new-directory collapse), and partial scope-expansion-approval failure (mid-sidecar-write OSError must leave the authoritative plan/worktree registry untouched, not half-applied). - Documented (xfail, strict=True) a separate, already-existing bypass in agent_baton/core/audit/dispatch_verifier.py's _is_under(): it uses PurePosixPath.relative_to(), which never collapses ".." segments, so a self-reported files_changed entry containing ".." lexically matches an allowed prefix while resolving outside it. That file is outside this step's allowed_paths -- see the report's "concerns" for the fix pointer.

Both are out_of_scope_diff_accepted holes. Add a directional path_within() primitive (candidate must equal or be nested under allowed; candidate's own segments are always literal; only the allowed side may carry a trailing '**' glob) and use it for the allow-list check. The blocked-path check stays bidirectional on purpose so a coarse collapsed directory that contains a blocked path is still flagged. Regression coverage added for path_within and both bypasses.

Lands the Python-level callable layer the CLI/MCP transport (deferred, §9) will call unchanged: - team_tools.py: canonical team_list/team_claim/team_update/team_send/ team_read tools alongside the unchanged legacy functions, a role-based authorization matrix (authorize_team_tool/authorized_team_tools/ advertised_team_tools_for_role), and TeamAuthorizationError/ TeamConcurrencyError exception subclasses. - team_board.py: TeamBoard.claim_task gains opt-in optimistic concurrency (expected_status="open") while its default stays last-writer-wins for legacy-behavior compatibility; append_task gains idempotency_key dedup; new done_tasks_for_team(); TeamBoardConflictError replaces a prior silent no-op on a missing/invalid task bead. - team_registry.py: TeamRegistry.set_status_if() — atomic compare-and-swap status transition, the guard the synthesis state machine design relies on. - models/execution.py: SynthesisState enum + SYNTHESIS_STATE_TRANSITIONS + is_valid_synthesis_transition(), the typed vocabulary for the synthesis state machine (not yet wired into persisted StepResult — documented as follow-up in the contract doc). - tests/test_team_tools.py: hermetic in-memory _FakeBeadStore (removes the existing tests' hidden dependency on the external bd binary) plus new coverage for all of the above.

No persistence guarantee, no authorization, no failure signal distinguishable from "the agent decided not to". | +| **Local MCP server** | Ship a stdio MCP server (`baton-team-mcp`) exposing the five tools; launch it per-dispatch via `ClaudeCodeLauncher.launch(..., mcp_servers=[...])` → `--mcp-config`, which **already exists** in `claude_launcher.py` (`_build_command`, `dispatcher.py:1147` already threads `step.mcp_servers` through). | Two structural blockers specific to *this* codebase: (1) an agent must declare `mcpServers:` in its frontmatter for Claude Code to load a configured server for that agent, and `agents/CLAUDE.md` documents that Agent Teams (`ClaudeTeamsBackend`) **does not honor `mcpServers:` frontmatter for teammates at all** — so the same tool surface would work under the `worktree` backend and silently vanish under `claude-teams`, exactly the "advertised tools don't match capabilities" bug this document exists to prevent. (2) it adds a second long-lived subprocess per dispatched team member, with its own handshake/timeout/crash semantics to design and test, for no capability the CLI can't already provide. | +| **Structured Baton CLI, invoked via the already-granted `Bash` tool** *(chosen)* | `baton team --json ...` subcommands. `team-lead.md` already grants `Bash`; every team member agent that can write code already has `Bash`. No new tool grant, no new subprocess-per-dispatch, works identically under both `WorktreeTeamBackend` and `ClaudeTeamsBackend` (the CLI doesn't care how the parent process was spawned — it talks to the same `baton.db` via `BATON_DB_PATH`/`BATON_TASK_ID`, which `claude_launcher.py`'s `_DEFAULT_ENV_PASSTHROUGH` already forwards to every launched subprocess). | — | + +### 2.2 Decision + +**Primary and only in-scope mechanism: a structured Baton CLI surface (`baton team +list|claim|update|send|read`), invoked by the dispatched agent through the `Bash` +tool it is already granted.** Each subcommand: + +- Accepts flags for every schema field in §4, plus `--json` for machine-readable + output (default: human-readable table, for interactive debugging). +- Exits `0` on success (JSON result on stdout), a documented non-zero code on + failure (§7.3) with a one-line error on stderr. +- Resolves `task_id` from `--task-id` → `$BATON_TASK_ID` → the active-task + pointer, matching the existing resolution order `baton execute` already + uses (`execute.py`'s `_RESUMABLE_STATUSES` active-task lookup) — a team + member never needs to know or pass its own `task_id` explicitly. +- Resolves the caller's `member_id` from `$BATON_TEAM_MEMBER_ID` (new env var, + §9.1) when `--member-id` is omitted, so a team member's prompt does not need + to hand-transcribe its own ID into every call (a source of typos today). + +MCP remains documented as a **future alternative**, not a competing mechanism: +if a later step adds first-class MCP support to `ClaudeTeamsBackend` (i.e. the +Anthropic-side gap in `agents/CLAUDE.md`'s teammate-safety note closes), the CLI +subcommands become trivial to also expose as MCP tool wrappers (`baton team +list` and an MCP `team_list` tool would call the identical Python functions in +§3) — the schemas and authorization matrix in this document do not change +either way. This is why the underlying Python implementation (§3) is kept +transport-agnostic: it never assumes CLI argv or MCP JSON-RPC, only typed +Python kwargs. + +### 2.3 The "advertised tools exactly match capabilities" invariant + +A dispatch prompt (or, later, CLI `--help` / MCP `tools/list`) must **never** +advertise a tool name the calling member cannot actually invoke. Two failure +modes this rules out: + +1. **Advertising a tool with no backing implementation** (the current bug — + `team-lead.md` names five tools; only the underlying Python functions + existed, no callable surface). +2. **Advertising a tool the caller's role is not authorized for** — e.g. an + `implementer` being told it can call `team_dispatch`. + +The single source of truth for "what may this role call" is +`agent_baton.core.engine.team_tools.advertised_team_tools_for_role(role) -> +list[str]`, backed by `TEAM_TOOL_NAMES` (the closed set: `team_list`, +`team_claim`, `team_update`, `team_send`, `team_read`, `team_dispatch`) and +the authorization matrix in §5. Any future code that renders a dispatch +prompt's "Tools" section (`dispatcher.py`) or builds a CLI `--help` string +must call this function rather than hard-coding a tool list — that is the +concrete mechanism that keeps the advertised surface from drifting from the +implemented one.

Authorization by task and member + +Authorization is **role-based**, keyed off `TeamMember.role` — resolved via +`_member_role(engine, task_id, member_id)`, which walks the *current* plan +(`state.plan.phases[*].steps[*].team`, including nested `sub_team`), not a +snapshot taken at dispatch time. This matters: `team_dispatch` can add +sub-team members mid-execution, and `_member_role` sees them immediately +because it re-reads `state.plan` on every call. + +| Role | `team_list` | `team_claim` | `team_update` | `team_send` | `team_read` | `team_dispatch` | +|---|:---:|:---:|:---:|:---:|:---:|:---:| +| `lead` | Y | Y | Y | Y | Y | Y | +| `implementer` | Y | Y | Y | Y | Y | — | +| `reviewer` | Y | Y | Y | Y | Y | — | +| *(unrecognized/custom role string)* | Y | Y | Y | Y | Y | — | + +**Design choice — fail-open on the board/mailbox tools, fail-closed only on +`team_dispatch`.** An unrecognized role string (a plan author's typo, or a +future role this document doesn't know about) still gets full board/mailbox +access. The alternative — fail-closed by default — would mean a single typo +in a plan's `role:` field silently locks a team member out of ALL +coordination with no error at authorization time (it would surface only +much later, as "why did this member never send a message"). `team_dispatch` +is the one tool where fail-closed is correct: standing up a sub-team is the +single highest-blast-radius operation in this surface (it mutates the plan +and registers new dispatch targets), so it alone is opt-in by an explicit, +recognized `role == "lead"`. + +Membership (task ↔ member ↔ team) is checked **before** role authorization +on every tool: `_require_member` raises a plain `TeamToolError` ("Member +'X' not found") for an unregistered `member_id`, so a typo'd member ID never +reaches the authorization check and gets the misleading "not authorized" +message — it gets the more actionable "doesn't exist" message. + +Authorization is enforced **once, at the tool-call boundary** +(`authorize_team_tool`), not re-derived per-field — there is no per-field +ACL (e.g. "implementer can `team_update` their own tasks but not others'"); +task ownership is enforced structurally instead (§6.1's `claimed_by` +concurrency check is the closest thing to a per-resource ACL, and it is a +concurrency guard, not an authorization guard — anyone authorized for +`team_claim` can attempt to claim any open task). + +--- + +## 6. Concurrency, mailbox delivery, and idempotency + +### 6.1 Optimistic concurrency — task claims + +`TeamBoard.claim_task(..., expected_status: str | None = None)`: + +- `expected_status=None` (default at the `TeamBoard` layer, used by the + **legacy** `team_claim_task`): last-writer-wins, unchanged from the + pre-existing implementation. Kept as the default specifically so + `tests/test_team_board.py::TestClaimTask::test_reclaim_replaces_previous_claim` + (outside this step's allowed paths, and outside its scope to change) + keeps passing — this document does not get to unilaterally redefine a + tested legacy behavior. +- `expected_status="open"` (always passed by the **canonical** `team_claim`, + unless `allow_reassign=True`): read-check-write — if the task is already + claimed by a *different* member, raise `TeamBoardConflictError` (wrapped + as `TeamConcurrencyError` at the `team_tools` boundary). Re-claiming your + own existing claim is a no-op success (safe retry after a timed-out + response whose actual outcome is unknown). + +**Known race window:** the check-then-write is two round-trips against the +underlying `BeadStore` (`read()` then `write()`), not a single atomic +statement — the `bd`-backed store has no compare-and-swap primitive to build +on (confirmed: `BdBeadStore.write()` itself does its own internal +read-modify-write via `bd show` / `bd update`). Two members racing to claim +the same task within that window can both observe `expected_status="open"` +and both write a claim; the later `write()` wins, silently overriding the +earlier claim WITHOUT raising `TeamBoardConflictError` (the conflict check +ran before either write landed). This is an accepted limitation for the +current single-process-per-task execution model (`ExecutionEngine` serializes +tool calls through one Python process per task; concurrent *team members* are +separate Claude Code **subprocesses**, but the CLI-mediated calls into +`team_tools` do not currently run inside those subprocesses — they run +inside whichever process eventually shells out to `baton team claim`, which +under the `worktree` backend is one call at a time from the orchestrating +loop). A true fix needs either a SQLite-backed claim table with a real +`UPDATE ... WHERE status='open'` guard (the pattern used for +`TeamRegistry.set_status_if`, §6.3) or a `bd`-side CAS primitive — flagged +as follow-up work (§9.2), not silently glossed over. + +### 6.2 Mailbox delivery + +Two delivery modes, both live simultaneously: + +1. **Push (existing, unchanged).** `BeadSelector.select_for_team_member` + injects unread messages into the next dispatch prompt automatically — + `references/team-messaging.md`'s "next dispatch, not real-time" semantics + are unchanged by this document. +2. **Pull (new — `team_read`).** A member can call `team_read` mid-turn to + check its mailbox without waiting for its next dispatch. `ack=True` + (default) immediately acks every message it returns, using the same + `message_ack` bead mechanism the push path already relies on + (`TeamBoard.ack_message`) — so a message pulled via `team_read` is NOT + re-injected into that member's next dispatch prompt. This is the correct + default: without it, every pulled message would be delivered a second + time via push, defeating the point of pulling early. `ack=False` exists + for a lead that wants to preview without committing to "I've seen this." + +No reply-threading, no interrupts — unchanged from the existing design. +Cross-task messaging remains unsupported (§ scope of +`references/team-messaging.md`). + +### 6.3 Team-level optimistic concurrency + +`TeamRegistry.set_status_if(task_id, team_id, expected_status, status) -> +bool` (new in this step) provides a real compare-and-swap, because +`teams` is a SQLite table this codebase owns directly (unlike beads, which +are mediated through the external `bd` CLI) — a single +`UPDATE teams SET status = ? WHERE task_id = ? AND team_id = ? AND status = ?` +statement is atomic within SQLite's own execution, no read-then-write race. +This is the guard the synthesis state machine (§8) uses to make sure two +concurrent synthesis drivers for the same team can't both "win" a state +transition. + +### 6.4 Idempotency + +- **`team_update` create mode**: `idempotency_key`, scoped to + `(team_id, idempotency_key)` via a `idem=` bead tag. A retried create + call with the same key returns the ORIGINAL `task_bead_id` — no duplicate + task is written. Scoped to create only; `team_update` complete mode is + naturally idempotent already (`BeadStore.close()` on an already-closed + bead is a safe no-op re-close). +- **`team_claim`**: re-claiming your own existing claim, §6.1. +- **`team_send` / `team_dispatch`**: NOT idempotent in this version — a + retried `team_send` after an ambiguous failure (e.g. CLI process killed + after the write landed but before the exit code was observed) writes a + second, duplicate message bead. This mirrors messaging semantics most + systems accept (at-least-once delivery, dedup is the reader's job) and is + explicitly a **non-goal** here — see §9.2. `team_dispatch` doubles as + idempotent in one narrow sense only: `TeamRegistry.create_team` already + no-ops on an existing `(task_id, team_id)` row (pre-existing behavior, + unchanged), but the `caller_member.sub_team.extend(new_members)` mutation + is NOT deduplicated — calling `team_dispatch` twice with the same members + list appends the roster twice. Flagged, not fixed, in this step. + +--- + +## 7. Audit events, timeouts, and failure behavior + +### 7.1 Audit events + +Every write (`team_send`, `team_update`, `team_claim`) already produces a +durable, queryable bead — the append-only bead store IS the audit trail +(`team_board.py`'s module docstring: "everything is append-only to the audit +trail"). This document does not add a parallel audit log; it strengthens +the existing one: + +- Every canonical tool call additionally emits a structured log line + (`_log.info`) naming `tool`, `task_id`, `member_id`, and + success/failure — a lightweight, always-on trace independent of whether + the call resulted in a bead write (e.g. an authorization failure never + reaches a bead write, but should still be observable). +- Follow-up work (§9.2): a dedicated `tool_call` bead type, so authorization + failures and concurrency conflicts — not just successful writes — land in + the same durable, queryable trail the rest of the system already uses. + Out of scope here because it touches `models/bead.py`'s + `KNOWN_BEAD_TYPES`/`TEAM_BOARD_BEAD_TYPES`, outside this step's allowed + paths. + +### 7.2 Timeouts + +No transport-level timeout exists yet in this step (§9.1 — the CLI +subcommands themselves are follow-up work). The design commitment for that +follow-up: `baton team ` inherits the same per-call SQLite/bd timeout +behavior the rest of the `baton` CLI already has (no bespoke timeout layer); +a caller-side timeout is the dispatched agent's own Bash-tool timeout +(already enforced by Claude Code itself), which is why `team_update`'s +idempotency key (§6.4) matters — a Bash-tool timeout on `team_update` leaves +the caller unsure whether the write landed, and the safe retry is "call +again with the same idempotency_key," not "assume it failed." + +### 7.3 Failure behavior — exception/exit-code taxonomy + +| Condition | Python exception | Planned CLI exit code | +|---|---|---| +| Unknown `team_id` / unregistered `member_id` / malformed `resource`/`status`/transition argument | `TeamToolError` | `2` (usage error) | +| Role not authorized for the requested tool | `TeamAuthorizationError` (`TeamToolError` subclass) | `3` (authorization error) | +| Optimistic-concurrency conflict (`team_claim`) | `TeamConcurrencyError` (`TeamToolError` subclass) | `4` (conflict — caller should re-`team_list` and retry against fresh state, not blindly retry the same claim) | +| Underlying store unavailable (`TeamRegistry`/`BeadStore` not configured — e.g. schema predates v15, or `bd` binary missing) | `TeamToolError` ("TeamRegistry is unavailable...") | `5` (backend unavailable — distinct from `2` so a caller/monitor can tell "your call was wrong" from "the environment is broken") | + +All four are `TeamToolError` subclasses (or `TeamToolError` itself) so a +caller that only wants "did this fail" can catch the base class; a caller +that wants to branch on *why* catches the specific subclass. No tool in +this surface fails silently — every rejected call raises; the days of +`claim_task` on a missing bead silently logging a warning and returning +`None` are over (§8.1 of the diff: `TeamBoard.claim_task` now raises +`TeamBoardConflictError` on a missing/wrong-type bead instead of warning +and no-op-returning — the prior behavior hid a caller bug behind a log line +only visible if someone was already looking). + +--- + +## 8.

Resolves task_id/member_id per the documented order (--flag > $BATON_TASK_ID/$BATON_TEAM_MEMBER_ID > active-task lookup), builds a real ExecutionEngine against the project's baton.db, and maps TeamToolError/TeamAuthorizationError/ TeamConcurrencyError/backend-unavailable onto the doc's exit-code taxonomy (2/3/4/5). Resolves .claude/team-context via BATON_TEAM_CONTEXT_ROOT/BATON_DB_PATH first so calls made from inside an isolated worktree target the parent project's db, not a worktree-local one. team_dispatch is intentionally not exposed here, matching the contract's explicit CLI scope (§2.2). - agent_baton/core/runtime/claude_launcher.py: launch() now injects BATON_TEAM_MEMBER_ID from its own step_id argument (authoritative and race-free — a team member's step_id IS its member_id by construction), rather than mutating shared os.environ, which would race across a StepScheduler wave's concurrently-dispatched launches. - agent_baton/core/engine/team_tools.py: closes two gaps the 4.1 architecture doc specified but didn't implement — (1) every canonical tool call now emits a structured _log.info audit line naming tool/task_id/member_id/outcome, independent of whether the call reached a bead write (doc §7.1); (2) a bead-store-unavailable engine (e.g. the `bd` binary missing) now raises a clean TeamToolError instead of an opaque AttributeError inside TeamBoard, matching the doc's "Underlying store unavailable" -> exit 5 row (§7.3). - agents/team-lead.md (+ bundled copy): removes the prompt-fiction team_send_message/team_add_task/team_claim_task/team_complete_task API and documents the real baton team CLI instead, including how a member resolves its own member_id/team_id and what each exit code means. team_dispatch's claim is revised to state plainly that no callable path exists for it yet, rather than implying it does. Regression tests: tests/test_team_tools.py (bead-store-unavailable + audit-logging), tests/test_claude_launcher_team_member_env.py (env injection + race-avoidance), tests/cli/test_team_cmd_runtime.py (end-to-end CLI flow across independent ExecutionEngine constructions, proving restart durability, plus the exit-code taxonomy).

Good shapes for a planner to +have predefined (worth calling out in your outcome if the actual work +doesn't match what was planned): a pipeline (one implementer per stage, +chained via `depends_on`), a fan-out (independent implementers on +parallel files converging at one synthesis point), or +integration-plus-specialists (you scaffold, each specialist owns one +adapter). Flag it as a deviation if you find overlapping file ownership +or unclear deliverables in a predefined sub-team — those cause merge +conflicts and wasted dispatch tokens respectively. ## Output Contract diff --git a/agent_baton/cli/commands/team_cmd.py b/agent_baton/cli/commands/team_cmd.py index 1b5c231b..00e1ed85 100644 --- a/agent_baton/cli/commands/team_cmd.py +++ b/agent_baton/cli/commands/team_cmd.py @@ -1,19 +1,42 @@ -"""``baton team status|show`` -- ad-hoc team status for a manager-mode task (M7). - -See docs/internal/manager-mode-pmo-plan.md Wave 2 / Task 10 and -docs/specs/agent-baton-claude-code-middle-manager-prd-tdd.md §8.3. - -``status`` prints: team purpose, roles (with owned-workstream counts), -current workstream ownership, completed handoffs, open knowledge gaps, open -scope changes, and manager decisions needed -- the PRD §8.3 field list. -``show`` prints everything ``status`` does, plus each role's full role-card -content (spec §14.2 template, via ``role_cards.render_role_card``). - -Task-id resolution and context-root discovery mirror -``agent_baton.cli.commands.report_cmd`` (itself mirroring +"""``baton team`` -- ad-hoc team status (M7) plus the team runtime-contract +CLI (Phase 4 4.2). + +Two independent surfaces share this module because they share the ``team`` +top-level argparse group (one entry point per group, per ``cli/CLAUDE.md``): + +- ``status`` / ``show`` -- manager-mode PMO team status and role cards.

Fails with a conflict (not a silent overwrite) if + someone else already holds it; pass `--allow-reassign` to force a + takeover (e.g. reclaiming a stalled task). +- `baton team update --team-id --member-id --title "" [--detail ""]` + — record a follow-up on the board (create mode). + `baton team update --team-id --member-id --task-bead-id --status complete --outcome ""` + — close a task you (or a peer) claimed, with an outcome summary. +- `baton team send --from-team --member-id --to-team [--to-member ] --subject "" --body ""` + — message a team or a specific member. Delivery is next-dispatch (or + the recipient's own `baton team read`), never an interrupt. +- `baton team read --team-id --member-id [--no-ack]` — pull + your unread mailbox mid-turn instead of waiting for your next dispatch. + Acks by default (`--no-ack` peeks without consuming). + +Exit codes are meaningful, not just pass/fail: `2` = bad input (e.g. +unknown team/member id — check for a typo), `3` = your role isn't +authorized for that verb, `4` = someone else already claimed the task +(re-run `baton team list` before retrying), `5` = the team backend isn't +configured in this environment (stop and report — do not retry). + +### Standing up a sub-team (current limitation) + +There is **no callable tool for `team_dispatch` in this runtime yet** — +unlike the five verbs above, standing up a sub-team mid-flight has no +CLI, MCP, or other callable surface a dispatched agent can invoke. Do +**not** narrate or simulate a `team_dispatch(...)` call; there is nothing +on the other end of it. If your task genuinely needs a sub-team that +wasn't predefined in the plan, say so explicitly in your outcome (a +`BEAD_WARNING:` or a plain statement of the need) so a human or the +planner can add it — do not claim you delegated when you did not. + +Sub-teams **predefined in the plan** (a `PlanStep.team` entry whose +member carries a non-empty `sub_team`) are dispatched normally by the +engine and need no action from you here. Good shapes for a planner to +have predefined (worth calling out in your outcome if the actual work +doesn't match what was planned): a pipeline (one implementer per stage, +chained via `depends_on`), a fan-out (independent implementers on +parallel files converging at one synthesis point), or +integration-plus-specialists (you scaffold, each specialist owns one +adapter). Flag it as a deviation if you find overlapping file ownership +or unclear deliverables in a predefined sub-team — those cause merge +conflicts and wasted dispatch tokens respectively. ## Output Contract diff --git a/tests/cli/test_team_cmd_runtime.py b/tests/cli/test_team_cmd_runtime.py new file mode 100644 index 00000000..5da8c572 --- /dev/null +++ b/tests/cli/test_team_cmd_runtime.py @@ -0,0 +1,337 @@ +"""Integration tests for the team runtime-contract CLI verbs (Phase 4 4.2): +``baton team list|claim|update|send|read``. + +Exercises the CLI handler functions directly (argparse.Namespace in, +stdout/SystemExit out) against a real ``ExecutionEngine`` + SQLite-backed +``TeamRegistry`` -- only the bead store is faked (the ``bd`` binary is not +installed in this sandbox; see ``tests/test_team_tools.py``'s +``_FakeBeadStore`` for the established hermetic pattern this mirrors). + +The fake bead store is keyed by db_path and shared across separate +``ExecutionEngine``/CLI-handler invocations within a test, which is what +lets "restart survives" be exercised meaningfully: each CLI call in these +tests constructs a brand-new ``ExecutionEngine`` (exactly as the real CLI +process does on every invocation), and state must be visible across that +boundary purely through the persisted backend -- no shared Python object +identity is relied upon except the keyed-by-db-path fake store standing in +for the real (equally persistent) ``bd``-backed store. +""" +from __future__ import annotations + +import argparse +import json +from pathlib import Path + +import pytest + +import agent_baton.cli.commands.team_cmd as team_cmd +from agent_baton.core.storage.sqlite_backend import SqliteStorage +from agent_baton.models.bead import Bead +from agent_baton.models.execution import MachinePlan, PlanPhase, PlanStep, TeamMember +from agent_baton.utils.time import utcnow_zulu as _utcnow + + +# --------------------------------------------------------------------------- +# Hermetic bead store -- keyed by db_path so separate ExecutionEngine +# constructions (simulating separate CLI process invocations / a restart) +# share the same persisted data, matching real BdBeadStore's durability +# without requiring the external `bd` binary. +# --------------------------------------------------------------------------- + + +class _FakeBeadStore: + def __init__(self) -> None: + self._beads: dict[str, Bead] = {} + + def write(self, bead: Bead) -> str: + self._beads[bead.bead_id] = bead + return bead.bead_id + + def read(self, bead_id: str) -> Bead | None: + return self._beads.get(bead_id) + + def close(self, bead_id: str, summary: str) -> None: + bead = self._beads.get(bead_id) + if bead is None: + return + bead.status = "closed" + bead.closed_at = _utcnow() + + def query( + self, + *, + task_id: str | None = None, + agent_name: str | None = None, + bead_type: str | None = None, + status: str | None = None, + tags: list[str] | None = None, + limit: int = 100, + ) -> list[Bead]: + out: list[Bead] = [] + for bead in self._beads.values(): + if task_id is not None and bead.task_id != task_id: + continue + if agent_name is not None and bead.agent_name != agent_name: + continue + if bead_type is not None and bead.bead_type != bead_type: + continue + if status is not None and bead.status != status: + continue + if tags and not set(tags).issubset(set(bead.tags or [])): + continue + out.append(bead) + out.sort(key=lambda b: b.created_at, reverse=True) + return out[:limit] + + +_FAKE_STORES: dict[str, _FakeBeadStore] = {} + + +def _fake_make_bead_store(db_path: Path, **_kwargs) -> _FakeBeadStore: + return _FAKE_STORES.setdefault(str(db_path), _FakeBeadStore()) + + +@pytest.fixture(autouse=True) +def _patch_bead_backend(monkeypatch: pytest.MonkeyPatch) -> None: + _FAKE_STORES.clear() + monkeypatch.setattr( + "agent_baton.core.engine.bead_backend.make_bead_store", + _fake_make_bead_store, + ) + + +@pytest.fixture +def context_root(tmp_path: Path, monkeypatch: pytest.MonkeyPatch) -> Path: + root = tmp_path / ".claude" / "team-context" + root.mkdir(parents=True) + #

A small carry-forward in record_step_result preserves member_results / synthesis_state / synthesis_dispatched across the intermediate "dispatched" write instead of losing them to the existing replace-on-step_id semantics. - conflict_handling is now enforced for all three values: auto_merge (synthesis agent dispatches and is expected to reconcile), escalate (pauses for APPROVAL, then resumes into a synthesis dispatch once approved -- the ESCALATED -> SYNTHESIZING edge), and fail (a new branch terminates the step on a same-file conflict even when no member itself failed, which was previously unhandled and fell through to auto_merge-like completion). - Updated tests/test_phase3_team_maturation.py assertions that encoded the old placeholder's synchronous-completion behavior for agent_synthesis; added tests/engine/test_team_synthesis_dispatch.py covering exactly-once dispatch (serial and parallel paths), restart safety, full completion/failure round trips, and all three conflict_handling values.

Also pins a real gap found while writing this coverage: conflict_handling='escalate' never resumes synthesis for concatenate/merge_files strategies after approval (only strategy='agent_synthesis' is wired to resume) -- executor.py is outside this step's allowed_paths so the fix is left for a follow-up; see the test's docstring and this commit's reported concerns. - tests/test_nested_team_dispatch.py: restart between dispatch and result (a fresh ExecutionEngine over the same on-disk state resumes without duplicating the dispatch wave or losing partial member results), and member-failure propagation that preserves sibling results instead of discarding them. - tests/test_team_step_routing.py: team-record CLI-handler restart safety across two members, and a malformed --member-id (not in the plan's roster) that must not crash or falsely complete the step. - tests/engine/test_team_backends.py: readiness diagnostics for 3-level nested teams (nested_team_count must reflect every level, not just the top one). Confirmed via git stash comparison that tests/test_team_board.py's existing bd-backed fixture and one pre-existing test in tests/test_multi_team_e2e.py already fail in this sandbox because the `bd` binary isn't installed -- same root cause as the two failures already carved out for this plan; not introduced here and left untouched.

In this sandbox (and per the environment note that only tests/test_bead_cmd_worktree_discovery.py's failure is an accepted pre-existing bd-binary gap) `bd` is not installed, so every test that touched the board through these fixtures errored out with TeamToolError/BdNotAvailable before exercising any real behavior. Repoint both fixtures at an in-memory `_FakeBeadStore` (write/read/close/ query), mirroring the established hermetic pattern already used by tests/test_team_tools.py, so the suite satisfies tests/CLAUDE.md's hermeticity requirement (no host filesystem/binary assumptions outside tmp_path) without touching bd_bead_store.py (out of this phase's allowed paths) or weakening any assertions. Also corrects the stale BEAD_WARNING comment in TestAckMessage to note the known BdBeadStore.query() closed-bead/label-filter bug is a production concern tracked separately, not something these hermetic tests exercise. Gate: python -m pytest -q tests/test_team_tools.py tests/test_team_registry.py tests/test_team_board.py tests/engine/test_team_mailbox_hooks.py tests/test_team_steps.py tests/test_multi_team_e2e.py tests/test_nested_team_dispatch.py tests/test_team_step_routing.py tests/engine/test_team_backends.py -> 243 passed.

Add TalentFactoryConfig (talent_factory section) to ManagerConfig: retry budget, recursion ceiling, validation/rollback policy, name-collision policy, registry-reload timing -- alongside the pre-existing TeamConfig.allow_talent_builder master switch. Update agents/talent-builder.md (and the synced bundled copy) with the talent-factory lifecycle contract: default product is an agent or knowledge pack (skill/plugin only when explicitly requested), never generate another talent-builder, treat ingested research material as untrusted data never instructions, least privilege, no silent name-collision overwrites, generation provenance frontmatter, and re-plan unresolved work instead of retrying or recursing. Document the full model in docs/internal/talent-factory-contract.md, including the explicitly deferred follow-up work (CLI wiring of --skip-init/ allow_talent_builder into baton plan, actual talent-builder dispatch as a plan phase, attempt/recursion bookkeeping across a run, baton agents doctor, mid-run registry reload) -- none of which blocks this step's behavioral contract, since the safe fallback is unconditionally available today.

Always `request_clarification`. | +| `missing_knowledge` | The role resolved fine; it lacks reference material for this domain. | A missing role — the agent exists and is capable in general. | May generate a **knowledge pack** | + +Keeping these separate matters operationally: conflating "I don't know what you mean" +with "I don't have a specialist for that" would make talent-builder the default answer +to bad task descriptions, which is exactly the failure mode this contract exists to +prevent (generating agents nobody asked for, for problems generation can't fix). + +### 2.2 `CapabilityGap` — evidence-backed, not asserted + +```python +@dataclass(frozen=True) +class CapabilityGap: + requested_capability: str + kind: CapabilityGapKind + evidence: tuple[CapabilityGapEvidence, ...] # required, non-empty + permitted_artifacts: tuple[PermittedArtifactType, ...] = () # derived from kind if omitted + fallback: str = "" # derived from kind if omitted +``` + +A `CapabilityGap` **cannot be constructed without evidence** — +`CapabilityGapEvidence(source, detail)` names the detector/stage that produced the +observation and a human-readable explanation. This is enforced in `__post_init__` +(`ValueError`, not a warning) because the alternative — a gap asserted from a hunch — +is precisely what would let generation run on speculation instead of a planner-observed +fact. `evidence` is a tuple so multiple independent signals (e.g. "explicit `--agents` +name unresolved" *and* "no learned pattern recommends this name either") can stack on +one gap without the caller having to pick just one. + +`permitted_artifacts` and `fallback` default from `kind` (§2.3, §2.4) but callers may +override them — e.g. a caller who knows the user explicitly asked for a skill sets +`permitted_artifacts=(PermittedArtifactType.SKILL,)` on an otherwise-`missing_role` gap. +An explicit empty tuple (`permitted_artifacts=()`) is a real value, not "unset" — it +means "nothing is currently authorized for this gap," and `decide_talent_lifecycle` +(§3) treats it as an automatic fallback regardless of other policy. + +### 2.3 `PermittedArtifactType` — the default product is an agent or a knowledge pack + +```python +AGENT, KNOWLEDGE_PACK, SKILL, PLUGIN +``` + +**Skill and plugin creation are out of scope for a bare capability gap.** The +kind→default-artifact table is deliberately narrow: + +| Gap kind | Default `permitted_artifacts` | +|---|---| +| `missing_role` | `(AGENT,)` | +| `missing_knowledge` | `(KNOWLEDGE_PACK,)` | +| `weak_task_description` | `()` — nothing is ever generated | + +Skill/plugin only enters `permitted_artifacts` when a caller **explicitly** constructs +a gap with that override (e.g. because the human said "turn this into a reusable +skill"). No detector in `capability_gap.py` defaults to it, and `agents/talent-builder.md` +is instructed accordingly (§9). This mirrors the existing Talent Builder decision +framework's five tests (`references/decision-framework.md`) — this contract narrows, +not replaces, that framework for the specific case of a planner-detected gap. + +### 2.4 Detectors — pure functions from planner-observable signal to gap-or-none + +| Function | Fires when | Evidence source | +|---|---|---| +| `detect_missing_role_gap(requested_agent, known_agents=...)` | An explicitly requested agent's base name (flavor suffix stripped) isn't in the registry's known base names. | `roster_stage.explicit_agent` | +| `detect_weak_description_gap(task_summary, min_words=3)` | The task summary has fewer than `min_words` words. | `classification.task_summary` | +| `detect_missing_knowledge_gap(role, domain=...)` | Always returns a gap — called only once the runtime knowledge-gap signal (`agent_baton/core/engine/knowledge_gap.py`) has already confirmed a role-level knowledge gap exists; this function just represents it in the same evidence-backed shape as the other two. | `knowledge_resolver` | + +Detectors never mutate anything — they observe and return `CapabilityGap | None` (or +always a gap, for the knowledge case). This keeps them trivially unit-testable and keeps +detection decoupled from what happens next (§3). + +**Current wiring** (this step): `RosterStage._detect_capability_gaps` calls +`detect_missing_role_gap` for every name in an explicitly-supplied `--agents` list, +against the set of base names the loaded `AgentRegistry` actually has definitions for. +It deliberately does **not** scan the default/pattern/concern-expansion roster — those +paths only ever draw from names the registry is already known to have, so running the +detector there would produce noise, not evidence. `detect_weak_description_gap` and +`detect_missing_knowledge_gap` are implemented and unit-tested but not yet called from +a pipeline stage — see §11. + +--- + +## 3. The bounded talent lifecycle + +Implementation: `decide_talent_lifecycle(gap, *, allow_talent_builder, skip_init, +recursion_depth, max_recursion_depth, attempts_used, retry_budget) -> +TalentLifecycleDecision`. + +### 3.1 `TalentLifecycleAction` — four possible outcomes, never a fifth + +| Action | Meaning | Who acts on it | +|---|---|---| +| `dispatch_talent_builder` | Generate: the gap is evidence-backed, policy permits it, budget remains. | Orchestrator dispatches talent-builder with the gap's `requested_capability` + `permitted_artifacts`. | +| `fallback_generic_agent` | Don't generate. Proceed with the closest existing generalist / existing knowledge. Never blocks the plan. | Roster keeps the caller's original request as-is (diagnostic only, see §3.3); execution-time dispatch falls back per `gap.fallback`. | +| `queue_for_manager` | Budget or recursion ceiling exhausted without resolving the gap. | Re-plan the unresolved work (§8) — never silently drop it, never retry indefinitely. | +| `request_clarification` | The gap is a description problem, not a capability problem. | Ask the caller; never generate. | + +### 3.2 Decision order (fixed — earlier checks are hard stops) + +1. **`weak_task_description` always → `request_clarification`.** No policy combination + overrides this — there is no configuration under which generating an agent for an + undescribed task is correct. +2. **Structural recursion guard.** `gap.requested_capability`'s base name in + `NON_GENERABLE_CAPABILITIES` (currently `{"talent-builder"}`) → `fallback_generic_agent`, + *unconditionally*, regardless of `allow_talent_builder`, `skip_init`, or budget. This + makes "talent-builder generates talent-builder" impossible by construction, not + merely policy-discouraged — see §7. Independently, `recursion_depth > + max_recursion_depth` → `queue_for_manager` (re-plan instead of nesting deeper; see §8). +3. **Explicit opt-outs.** `skip_init=True` → `fallback_generic_agent` (`--skip-init` CLI + override, or any equivalent programmatic override). `allow_talent_builder=False` → + `fallback_generic_agent` (`TeamConfig.allow_talent_builder`, still the master on/off + switch — see §4). +4. **Retry budget.** `attempts_used >= retry_budget` → `queue_for_manager` (§10). +5. **No permitted artifacts.** `gap.permitted_artifacts` is empty → `fallback_generic_agent` + (covers both the `weak_task_description` default and any caller-constructed gap with + an explicit empty override, §2.2). +6. Otherwise → `dispatch_talent_builder`. + +Every `TalentLifecycleDecision` carries `gap` (the full evidence trail) and `reason` (a +one-line human-readable explanation of which check fired) — both round-trip through +`to_dict()` for `plan_diagnostics` and audit logs. + +### 3.3 What "bounded" means at plan time vs. execution time + +This step's pipeline integration (`RosterStage`) calls `decide_talent_lifecycle` once, +at plan-construction time, with `recursion_depth=0`, `max_recursion_depth=0`, +`attempts_used=0`, `retry_budget=1` (the function's defaults) — i.e. "is this a +first-generation gap and is generation policy-permitted at all." The decision is +**diagnostic only**: it is recorded on `plan.plan_diagnostics["capability_gaps"]` / +`["talent_lifecycle_decisions"]` and as a routing note; it does not mutate +`draft.resolved_agents`, so a caller's explicit `--agents` list is preserved as given +and a plan still assembles even when a gap is detected. Actually dispatching +talent-builder, tracking `attempts_used` across retries within one run, and deriving +`recursion_depth` from an artifact's own generation ancestry are execution-time +concerns handed off in §11 — the function signature already accepts the parameters a +future execution-time caller needs; this step does not yet supply non-default values +for them. + +--- + +## 4. Policy: `allow_talent_builder` and `--skip-init` + +Two independent knobs, both already named before this step, now both consumed by +`decide_talent_lifecycle`: + +- **`team.allow_talent_builder`** (`TeamConfig` in `agent_baton/core/config/manager.py`, + default `True`) — the master on/off switch for talent-builder participation at all. + `False` means "this project never wants generated capability," full stop. +- **`--skip-init`** (`baton plan` CLI flag) — a per-invocation override: "don't + auto-initiate talent-builder for *this* plan even if the project would otherwise + allow it," e.g. because `.claude/agents/` is empty and the caller wants the bundled + generic roster instead of triggering generation. + +Both map onto `IntelligentPlanner.create_plan(..., skip_init: bool = False, +allow_talent_builder: bool = True)`, which threads them onto `PlanDraft.skip_init` / +`PlanDraft.allow_talent_builder` for `RosterStage` to read. **Defaults preserve prior +behavior** (generation permitted, nothing skipped) so this addition is backward +compatible for every existing caller. + +`TalentFactoryConfig` (new section on `ManagerConfig`, key `talent_factory` in +`baton.yaml`) governs the generation *lifecycle* once talent-builder is otherwise +permitted to run — retry budget, recursion ceiling, validation/rollback policy, name +collision policy, registry reload timing (§5–§10). `team.allow_talent_builder` stays on +`TeamConfig` for backward compatibility; `talent_factory` is additive. + +```yaml +team: + allow_talent_builder: true # master switch (pre-existing) + +talent_factory: # new section (this step) + default_permitted_artifacts: [agent, knowledge_pack] + retry_budget: 1 + max_recursion_depth: 0 + require_validation: true + on_validation_failure: rollback # rollback | quarantine + name_collision_policy: reject # reject | version_suffix | manual_review + registry_reload: immediate # immediate | next_plan +``` + +--- + +## 5. Generated agent/pack/skill validation + +`talent_factory.require_validation` (default `true`) gates whether a generated artifact +is usable before it is validated. Validation criteria, by artifact type: + +- **Agent** — must satisfy the pre-existing Generated-Agent Contract already documented + in `agents/talent-builder.md` and `references/agent-authoring.md`: required + frontmatter (`name`, `description`, `model`, `permissionMode`, `tools`), required body + sections (Mission, Before Starting, Knowledge References, Principles, Anti-Patterns, + Output Format), every path named under "Knowledge References" must resolve, and + `name` must match the filename. This step does not add a new checker — it makes + passing this contract a hard precondition for a generated agent to be registered, + per `on_validation_failure` below. (A machine-checkable `baton agents doctor` command + implementing this mechanically is tracked in §11 and in + `reference_docs/framing_and_roadmap/03-talent-builder-subagent-management.md` Phase 2; + it does not exist yet, so validation is currently talent-builder's own read-back + + checklist step, per its updated instructions.) +- **Knowledge pack** — every file the pack's manifest/frontmatter references must exist + under the pack directory; at minimum an `overview.md` under 50 lines per + `agents/talent-builder.md`'s existing knowledge-pack format rules. +- **Skill/plugin** — out of scope by default (§2.3); when explicitly authorized, must + satisfy the existing `SKILL.md` frontmatter contract (`name`, `description`). + +### 5.1 On validation failure + +`talent_factory.on_validation_failure`: + +- **`rollback`** (default) — discard the artifact entirely (delete the file(s) just + written) and apply `gap.fallback`. An invalid artifact must never be left registered + or half-written on disk; "fail closed" here mirrors the repo-wide convention (see + `BATON_COMPLIANCE_FAIL_CLOSED` for the analogous pattern in the compliance subsystem). +- **`quarantine`** — keep the file on disk with `status: draft` (or an explicit + `status: rejected` marker) for human review, but do not register it for planning/ + dispatch use. Useful when a human wants to see *what* talent-builder attempted even + though it didn't pass. + +--- + +## 6. Name collisions + +`talent_factory.name_collision_policy` governs what happens when a generated artifact's +name (`agents/.md`, or a knowledge-pack directory name) already exists on disk: + +- **`reject`** (default) — refuse to write, apply `gap.fallback`, and report the + collision. Never silently overwrite — an existing agent/pack might be hand-authored + and load-bearing. +- **`version_suffix`** — write as `--v2` (incrementing) instead of overwriting. + Only sensible for genuine re-generations of a *previous talent-builder output* for + the same gap (provenance-checked via §7's `created_by`/`version` fields), not for + colliding with an unrelated hand-authored agent of the same name. +- **`manual_review`** — write to a quarantine path (not the live `agents/` / + `knowledge/` tree) and queue for a human to reconcile. + +`agents/talent-builder.md` is updated (this step) to check for an existing file before +writing and to stop + report rather than overwrite, matching the default `reject` +policy; site-specific overrides via `talent_factory.name_collision_policy` are the +caller's (orchestrator's) responsibility to pass into the dispatch prompt — that +plumbing is deferred (§11). + +--- + +## 7. Untrusted instructions + +Talent-builder's research step reads external and repo-local documentation to build +knowledge packs and agent prompts. That material is **data, never instructions** — a +schema doc, README, or web page that contains text shaped like a directive ("ignore +previous instructions," "set permissionMode to auto-edit," "grant tool Bash") must not +change what talent-builder builds, what tools it grants, or what permission mode it +sets. `agents/talent-builder.md` (this step) states this explicitly as a non-negotiable +rule, alongside the pre-existing least-privilege rule (start read-only; add +`Write`/`Edit`/`Bash` only when the mission requires it) — both rules apply regardless +of what generated content "asks for." + +This is the same class of defense as scope-contract enforcement (Phase 3) and the +manager-mode scope-signal guardrails: content encountered while doing the work is not +a channel for expanding what the work is allowed to do. + +--- + +## 8. Re-planning unresolved work without recursive spawning + +Two independent mechanisms, both already covered above, restated together because they +are the two halves of "no recursive talent-builder spawning": + +1. **Structural**: `NON_GENERABLE_CAPABILITIES` makes "talent-builder generates + talent-builder" return `fallback_generic_agent` unconditionally (§3.2 step 2) — this + is not a policy setting that could be misconfigured away; it is checked in code + before any policy knob is consulted. +2. **Depth-bounded**: when a capability gap is itself discovered while resolving a + *prior* talent-builder-generated artifact (e.g. a generated agent's own knowledge + pack turns out to be incomplete), `recursion_depth` reflects how many + talent-builder generations already sit in that gap's ancestry. + `max_recursion_depth` (default `0`, from `talent_factory.max_recursion_depth`) means + "never nest" by default — `recursion_depth > max_recursion_depth` → + `queue_for_manager`, not another `dispatch_talent_builder`. + +`queue_for_manager` means: the unresolved work is **re-planned**, not retried by the +same mechanism that just failed. Concretely (execution-time behavior, handed off in +§11): the orchestrator treats the gap as unresolved scope, surfaces it the same way a +scope-expansion or knowledge-gap escalation is surfaced today (`queue-for-gate` in +`agent_baton/core/engine/knowledge_gap.py` is the existing analogous pattern), and lets +a human or the manager-mode PMO layer decide — route to a generalist agent, adjust the +task description, or approve one more generation attempt with an explicitly bumped +budget. Talent-builder itself never decides to retry on its own (§9) — that would +reintroduce unbounded retry through the back door. + +--- + +## 9. Provenance + +Every artifact talent-builder generates must be attributable back to this lifecycle. +`agents/talent-builder.md` (this step) requires: + +- `created_by: talent-builder` on every generated agent's frontmatter (already a + recommended field per the pre-existing Generated-Agent Contract; this step makes it + mandatory for talent-builder's own output, not just recommended). +- `status: draft` and `version: 0.1.0` (or the next patch version for a + `version_suffix` re-generation, §6) on first generation, so `status`-aware tooling + (the draft/review/promote lifecycle described in + `reference_docs/framing_and_roadmap/03-talent-builder-subagent-management.md` Phase + 3) can distinguish generated-and-unreviewed capability from a promoted, trusted + roster agent. +- The dispatching gap's evidence (`CapabilityGap.to_dict()`) is available in + `plan.plan_diagnostics["capability_gaps"]` for audit — a generated artifact should be + traceable back to the specific evidence that justified its creation, not just a + timestamp. + +--- + +## 10. Retry budgets + +`talent_factory.retry_budget` (default `1`) bounds `attempts_used` in +`decide_talent_lifecycle` (§3.2 step 4): once `attempts_used >= retry_budget`, the +lifecycle stops offering `dispatch_talent_builder` for that gap and escalates to +`queue_for_manager` instead. A budget of `1` means exactly one generation attempt per +gap per plan before escalation — deliberately conservative, since an unbounded retry +loop against a capability gap that's fundamentally unresolvable (e.g. the domain +described genuinely doesn't map to anything buildable) is indistinguishable from a +runaway loop from the outside. Sites that want more attempts set +`talent_factory.retry_budget` higher; the function never has an "unlimited" mode. + +--- + +## 11. Follow-up work (explicitly deferred, not done in this step) + +This step delivers the **model and policy** (`capability_gap.py`, `TalentFactoryConfig`, +the `RosterStage` diagnostic-only integration, and the updated `talent-builder.md` +contract). It deliberately does not: + +1. **Thread `--skip-init` / `team.allow_talent_builder` from `baton plan` into + `create_plan()`.** `agent_baton/cli/commands/execution/plan_cmd.py` is outside this + step's allowed paths. `IntelligentPlanner.create_plan()` already accepts + `skip_init`/`allow_talent_builder` kwargs (this step) — the CLI wiring is a small, + low-risk follow-up: parse `args.skip_init` (already parsed, currently unused) and + load `ManagerConfig.team.allow_talent_builder` before the `create_plan()` call + (today `ManagerConfig` loads *after* `create_plan()` in `plan_cmd.py`, so the load + order needs to move earlier). +2. **Actually dispatch talent-builder as a plan phase/step** when + `TalentLifecycleAction.DISPATCH_TALENT_BUILDER` is decided. Today the decision is + recorded in `plan_diagnostics` for visibility; inserting a generation phase ahead of + the phase that needs the missing role (and gating that phase on validation, §5) + is execution-pipeline work, not planning-model work. +3. **`attempts_used` / `recursion_depth` bookkeeping across an actual run.** The + function signature supports it; nothing yet persists attempt counts or ancestry + between dispatches. Natural home: alongside the existing bead-based tracking + (`agent_baton/core/engine/bead_signal.py`) or a small sidecar next to + `.claude/team-context/executions//`. +4. **`baton agents doctor`** — mechanical validation of the Generated-Agent Contract + (§5). Tracked pre-existing in + `reference_docs/framing_and_roadmap/03-talent-builder-subagent-management.md` Phase + 2; `agent_baton/cli/commands/agents/` is outside this step's allowed paths. +5. **`registry_reload: immediate`** actually reloading a live `AgentRegistry` + mid-plan. `AgentRegistry` today is loaded once per `IntelligentPlanner` instance + (`__init__` → `load_default_paths()`); making it reloadable mid-run is a registry + change, not a planning-model change. +6. **`detect_weak_description_gap` / `detect_missing_knowledge_gap` pipeline wiring.** + Both are implemented and unit-tested (`tests/test_planner.py`) but not yet called + from `ClassificationStage` / the runtime knowledge-gap path respectively — see §2.4. + +None of the above blocks this step's behavioral contract: *"the planner can represent +an evidence-backed capability gap and apply a bounded, policy-controlled generation +lifecycle with a safe fallback"* — §2–§3 deliver exactly that, independent of whether +anything downstream yet acts on `dispatch_talent_builder`. The safe fallback +(`fallback_generic_agent`) is unconditionally available today: a plan with an +unresolved capability gap still assembles and still runs, with the gap visible in +`plan_diagnostics` rather than silently swallowed. + +--- + +## 12.

7c53da452547365750e3b63fae4c48efcd1ed157 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 17 Jul 2026 01:56:35 +0000 Subject: [PATCH 26/43] phase 5 5.2: implement capability-gap dispatch, validation, and bounded re-planning Wires the talent-factory lifecycle (5.1's model) to real behavior: - IntelligentPlanner.create_plan() now runs classification+roster first, acts on any DISPATCH_TALENT_BUILDER decision via the new planning/talent_factory.py module, then continues risk..assembly with the resolved roster ("re-plan only the unresolved step" without re-running the full pipeline). - talent_factory.py performs exactly one bounded dispatch attempt per gap through a pluggable TalentBuilderDispatcher (production: HeadlessTalentBuilderDispatcher, the same synchronous/verified launcher already used for plan review); validates the artifact (generated_agent_validator.py: frontmatter/schema, allowed models/tools, provenance, body sections, prompt-safety scan, recursion guard), atomically installs it under name-collision policy, and reloads the registry via new AgentRegistry.register_generated_agent / KnowledgeRegistry.register_generated_pack. Every write happens in a scratch directory first and is rolled back on any failure. - Failed/disallowed/skipped generation resolves to a deterministic generic-agent fallback (or TalentFactoryError if the registry truly has no candidate) -- never a phantom, undispatchable agent name in the final plan. - plan_cmd.py: --skip-init and ManagerConfig.team.allow_talent_builder / talent_factory now actually reach create_plan() (config load moved earlier); baton plan is the one call site that wires a live HeadlessTalentBuilderDispatcher. IntelligentPlanner's own default stays a no-op NullTalentBuilderDispatcher so constructing a planner never starts a live `claude` subprocess as a side effect -- required for hermeticity across the existing test suite, which constructs IntelligentPlanner() directly in many places. - Updated two pre-existing tests whose assertions encoded the old "unresolved agent name flows through unchanged" behavior, now superseded by real resolution before phase construction.

ac62d90fccd4a716e5c8994a993e8bfbcc7a5b4a Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 17 Jul 2026 02:13:42 +0000 Subject: [PATCH 27/43] phase 5 5.3: talent-factory lifecycle test coverage (fake builders, rollback, config wiring) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Extends the talent-factory test suite within this step's allowed test paths, complementing the tests already landed alongside 5.1/5.2 (tests/test_talent_factory.py, tests/test_generated_agent_validator.py, tests/cli/test_plan_cmd_talent_factory.py -- outside this step's scope): - tests/engine/planning/test_headless_talent_builder_dispatcher.py (new): process-failure coverage for the one dispatcher that actually shells out -- CLI-not-found, a raised subprocess exception, non-zero exit, empty/whitespace output, code-fence unwrapping, and prompt content (gap evidence + explicit anti-recursion instruction), all against a mocked HeadlessClaude so no real `claude` subprocess runs. - tests/engine/planning/test_talent_factory_rollback_and_collision.py (new): the run_talent_factory_for_gap cases not yet covered anywhere -- name_collision_policy=manual_review (quarantine, never overwrite/ register), install-time registry re-parse failure rolling the just-written file back out, a path-escaping frontmatter `name` (defense in depth via the kebab-case validator, verified against the real filesystem so "no artifact remains after a failed validation" is checked as a filesystem invariant, not just ValidationResult.valid), and malformed-frontmatter / unsafe-tool-request end to end. - tests/test_planner.py: registry_reload=immediate proven causally -- a second create_plan() call on the same planner instance reuses a just-generated agent with zero capability gaps and zero re-dispatch; telemetry coverage for routing_notes + plan_diagnostics shape on both the generated and fallback outcomes. - tests/engine/planning/test_planner_diagnostics.py: build_plan_diagnostics preserves capability_gaps/talent_lifecycle_decisions/ talent_factory_outcomes verbatim across a re-diagnostics pass (e.g. a goal-driven amend cycle), and defaults them to empty rather than raising when a plan never hit a capability gap. - tests/manager/test_manager_config.py: TalentFactoryConfig defaults, YAML section loading (full + partial override), invalid Literal rejection for all three enum fields, to_dict/from_dict round-trip, and backward compatibility loading the pre-talent-factory PRD §9.1 spec YAML. - tests/cli/test_plan_manager_mode_save.py: pins that --manager-mode still threads skip_init/allow_talent_builder/talent_factory_config into create_plan() after the config-load reordering in plan_cmd.py -- a regression here would silently diverge manager-mode wiring from the plain-`baton plan` wiring already covered elsewhere. Verified: all new/edited test files pass in isolation and together (tests/engine/planning, tests/manager, tests/agents, tests/test_planner.py, tests/cli/test_plan_manager_mode_save.py, tests/test_engine_planner.py). The 17 failures observed in that combined sweep are pre-existing on this branch with none of this step's changes applied (confirmed via git stash) -- ValidationStage review_missing/agent_phase_mismatch defects in tests/test_engine_planner.py and the already-documented test_planner_smoke.py::test_medium_task_produces_standard_plan -- none touch talent-factory code or tests and none are in this step's allowed paths.

Added _prune_unused_resolved_agents, run once after team consolidation, to drop roster candidates that never got a step after every agent-dropping stage (subtask-union, concern-split, reviewer-filtering) has had its turn. _has_review_coverage now accepts any non-implement-type phase (not just a literal "Review" name), covering the "investigation" archetype's Verify phase and an explicit --agents roster applied wholesale to compound-task subtask phases. Fixed a "team" consolidation-sentinel leaking into agent-base evidence (_step_agent_bases). - phase_builder.py: Pass 3 of assign_agents_to_phases ("reuse best-fit from pool") now also blocks reviewer-class agents from implement-type phases (PHASE_BLOCKED_ROLES["draft"] was empty), so a caller-supplied roster of just a reviewer agent falls through to the engineer fallback instead of getting illegally assigned to Draft with no recovery. Scoped to Pass 3 only -- Pass 2/4 keep their original tolerance for reviewer overflow into work phases per TestAgentOverflowToWorkPhases. - tests/test_engine_planner.py: registered devops-engineer, devops-specialist, and security-reviewer in the risk-assessment fixture registry so TestRiskAssessmentStructural exercises the risk keyword heuristic in isolation, without also tripping the capability-gap/talent-factory machinery for an agent name unknown to a deliberately minimal test registry (talent_factory.py's fallback-substitution behavior for unresolved gaps is itself required by tests/test_planner.py's TestPlannerCapabilityGapIntegration and left untouched). The 16th originally-failing test (test_planner_smoke.py::test_medium_task_produces_standard_plan) is pre-existing, live-classifier-driven flakiness explicitly called out as out of scope for this repair; confirmed unrelated by reproducing the identical agent_phase_mismatch signature transiently on an unrelated test in this same run and observing it pass reliably in isolation.

The plan was invalid because IntelligentPlanner() built with no explicit task_classifier defaults to FallbackClassifier, which tries a real Sonnet call via HeadlessClaude whenever the `claude` binary is reachable on PATH (_talent_agent_available() only checks binary presence, never an opt-in flag or ANTHROPIC_API_KEY). This sandbox has `claude` on PATH, so every "unit" test in tests/engine/planning and tests/test_engine_planner.py that called create_plan() with no explicit agents/task_type was silently making a live, network- dependent LLM call instead of exercising the documented "mock mode by default" contract -- the model was free to recommend any registered agent for any phase, including a reviewer-class agent for an Implement-type phase. The prior phase-5 gate-repair commit newly registered security-reviewer/devops-engineer in the shared tmp_agents_dir fixture, which put those agents in the live classifier's candidate pool and turned this latent nondeterminism into an intermittent PlanQualityError with no correlation to any code change. tests/CLAUDE.md mandates hermetic tests (no real network/CLI calls); this was a pre-existing violation of that contract, newly exposed rather than newly introduced. Fix: force the TalentAgent probe unavailable for the affected test files/directory (autouse fixture patching agent_baton.core.engine.classifier._talent_agent_available), so FallbackClassifier always falls through to the deterministic KeywordClassifier, unless a test opts into BATON_PLANNER_INTEGRATION=1 (the flag test_planner_smoke.py already documents for real end-to-end coverage). Added tests/engine/planning/test_classifier_hermeticity.py as the regression test: asserts the probe is forced off, and that 8 repeated create_plan() calls on identical input produce byte-identical plans with no reviewer-class agent ever landing in an Implement-type phase -- verified this fails (assert True is False / security-reviewer misplacement) with the conftest fixture removed. Full gate green twice in a row: 685 passed, 7 skipped, 0 failed.

The resolved TalentFactoryConfig is now set on the draft before the pre-pipeline runs and RosterStage reads retry_budget/max_recursion_depth from it. 2. Duplicate entries in an explicit --agents list created two gaps for the same capability: the second dispatch collided with the first's freshly installed artifact and its collision-fallback substitution rewrote the successful resolution out of the roster, so the generated agent was installed but never causally used (and talent-builder was dispatched twice for one gap). Gap detection now dedupes requested capabilities. 3. validate_generated_agent only checked that permissionMode was present, so a generated artifact declaring permissionMode: bypassPermissions (the frontmatter flavor of the 'set permissionMode to auto-edit' injected directive contract §7 warns about) passed validation and was auto-installed and auto-registered with no human review. Generated drafts are now restricted to ALLOWED_PERMISSION_MODES = {default, plan}; the headless dispatcher prompt pins permissionMode: default. Regression tests added for all three; talent-factory-contract.md §3.3 updated to match, §11 annotated with what step 5.2 delivered.

Strictly additive over phase_builder's existing template output and a clean no-op whenever there's no project_root or no matching evidence, so deterministic template-based behavior is unchanged when grounding has nothing to add. Wired into DecompositionStage._build_phases, gated on inferred_complexity == "heavy", before enrich_phases's generic-default fill so grounded fields are never overwritten by templates. - planning/utils/phase_normalize.py: repairs phase/step references that go stale when ForesightEngine.analyze inserts a phase ahead of an existing one and renumbers everything after it -- the "Build on the ... output from phase N" text phase_builder.enrich_phases bakes in before foresight runs would otherwise keep naming a phase number that no longer refers to what it meant. Snapshots phase/step identity->id before the restructuring call and diffs against the post-mutation state to rewrite depends_on edges and the narrow, self-authored "from phase N (" text pattern -- never touches arbitrary director-authored prose. Wired into DecompositionStage._apply_foresight around the ForesightEngine.analyze call. - ValidationStage: three new heavy-task-only defect checks in _detect_shallow_decomposition. generic_placeholder (critical/blocking) fires on unambiguous literal placeholder markers (tbd/todo/placeholder/ lorem ipsum). bare_agent_template and empty_deliverables/empty_scope are warnings (surfaced as diagnostics via score_warnings/ plan_diagnostics, non-blocking) -- STEP_TEMPLATES's per-agent/per-phase coverage has real, currently-legitimate gaps and grounding is opportunistic (many valid plans have no project_root to ground against), so blocking on those would reject real, otherwise-fine plans; confirmed via a regression run against tests/test_engine_planner.py's TestOriginalProblemScenario before settling on this split. Regression coverage: tests/engine/planning/test_repo_grounding.py, test_phase_normalize.py (including a real ForesightEngine integration case), and a new TestShallowDecompositionDetection class in test_validation_stage.py. Verified no regressions beyond the pre-documented ones (gate-scope stack-detection flakiness, two governance policy-violation tests, one explicit-phases-guard test, and the 4 known live-claude-nondeterminism golden-snapshot cases) across tests/engine/planning/, tests/test_planner_quality.py, tests/test_planner_governance.py, tests/test_planner_gate_scoping.py, tests/planning/, tests/test_engine_planner.py, tests/test_archetype_decomposition.py, tests/api/test_specs_api.py, tests/test_api_pmo.py, tests/test_pmo_forge.py, tests/test_foresight.py, tests/test_plan_reviewer.py, tests/test_planner.py, and tests/manager/test_manager_mode_planner.py.

BATON_CHECKPOINT_ENABLED gates the feature) at the only safe, already- persisted boundary: immediately after a phase fully advances (PHASE_ADVANCE_OK / EMPTY_PHASE_ADVANCE) and before anything in the new phase is dispatched. - _build_checkpoint_handoff / _emit_checkpoint build and persist a compact CheckpointHandoff (goal, completed outcomes, decisions, scope, changed files, unresolved risks, next actions, exact resume command) onto the new ExecutionState.checkpoints list, and advance dedup markers (last_checkpoint_phase/turn_count/tokens, checkpoint_count) so the same phase boundary can never checkpoint twice -- including across an investigative-archetype retry_phase loop. - next_actions() (plural) withholds its dispatchable batch when a checkpoint is due but not yet emitted, so every existing caller (TaskWorker, the REST API's _collect_next_actions, `execute next --all`) naturally falls back to next_action() (singular), the only place that actually emits + persists the checkpoint. - TaskWorker, the CLI's _print_action/_run_loop, and the PMO pending-gates scan all treat CHECKPOINT as a non-terminal paused-for-refresh signal -- never as COMPLETE or FAILED. - Closes a pre-existing gap where ExecutionState.turn_count had no to_dict()/from_dict() roundtrip support at all (needed for the turn-count threshold to survive a reload across CLI processes). Verified end-to-end via ad-hoc scripts (fresh-process resume with no redispatch, plural-dispatch withholding, dedup across sequential checkpoints, worker non-terminal handling, disabled flag) since tests/ is outside this step's allowed_paths; full existing suites (tests/engine, tests/test_executor.py, tests/models, tests/runtime, tests/cli, tests/api -- 1557 tests) pass unchanged.

A failure leaves every previously published file, and the immutable decision-log/decisions/ scope-evidence trees, untouched. artifacts.py gains render_all() (pure (path, text) rendering, extracted from write_all so rebuild.py can stage without writing); paths.py gains revision_manifest. Wires this into every executor.py path that adds phases/steps to a manager_mode plan: amend_plan() (covers scope-expansion phase generation, feedback dispatch, approval-feedback remediation, and manual/CLI amendments) snapshots state.plan/gate_results/approval_results/ feedback_results, mutates as before, and only commits once the rebuild reports ok=True -- otherwise everything is rolled back and ManagerArtifactPublishError is raised. The goal round-out path in _evaluate_goal_after_gate gets the same snapshot/rollback treatment inline (it can't call amend_plan -- see its own docstring). approving a scope-expansion decision now also runs a best-effort full rebuild after its existing narrow contract-sidecar patch, so the rest of the artifact set stays current too. Non-manager_mode plans take none of these new code paths and are behaviorally unchanged. Along the way, found and fixed two adjacent defects the new coverage surfaced: (1) _process_pending_expansions called amend_plan() (which has no `state` param and persists its OWN reloaded copy) without ever refreshing its own `state` reference, so its trailing _save_execution(state) silently reverted every scope-expansion amendment it had just applied -- not manager-mode-specific, fixed by pulling the freshly-amended fields back onto the same state object after each successful amend_plan() call; (2) record_feedback_result's dispatched_step_id lookup matched on amendment.phases_added (documented as the PRE-renumber placeholder id) against the POST-renumber plan reloaded from disk, so it could never match and dispatched_step_id was always left empty -- fixed by matching on the inserted phase's (renumber- stable) name instead. Also wires dispatch-outcome correlation into the resolver's own knowledge telemetry: knowledge_telemetry.py gains record_dispatch_outcome(), called from record_step_result() on every terminal StepResult so KnowledgeUsed rows get an outcome_correlation instead of staying NULL forever. And context_bundles.py's phantom-knowledge-pack fallback (a required pack name that never landed in the knowledge plan's selected_packs) now surfaces a truncation_warning instead of silently attaching a content-less reference.

From 2457aaa19a8af686238e9409e32367db90695681 Mon Sep 17 00:00:00 2001 From: Claude Date: Fri, 17 Jul 2026 06:24:02 +0000 Subject: [PATCH 34/43] phase 6 6.4: quality and continuity regression suite for planning/checkpoint/sidecars Adds the test coverage 6.1-6.3 shipped without (6.2 explicitly deferred it; 6.3 covered rebuild/rollback/telemetry in isolation but not the full dispatch-time integration): - tests/cli/test_execute_run_resume.py: CHECKPOINT threshold (phase_interval, turn_threshold, token_threshold, independently), dedup (same phase boundary never checkpoints twice), the BATON_CHECKPOINT_ENABLED=0 escape hatch, and next_actions() withholding its dispatchable batch when a checkpoint is due -- at the bare-engine level, through `baton execute run` (a checkpoint stops the CLI loop cleanly and a wholly independent second invocation resumes past it without redispatching phase 1 or re-checkpointing), and through TaskWorker (treats CHECKPOINT as non-terminal, and a fresh worker/engine pair resumes cleanly). - tests/engine/test_manager_context_prompt.py: the checkpoint + scope- amendment scenario -- a step's scope is widened and its sidecars republished (new revision) *after* a checkpoint has already fired and *before* the amended step is ever dispatched; a brand-new ExecutionEngine instance (simulating the fresh session the checkpoint's own resume command points at) must dispatch with the amended scope contract, not the sidecars that were current when the checkpoint fired. Also pins that checkpoint dedup survives the amendment. - tests/engine/planning/test_repo_grounding.py: a full-pipeline create_plan() snapshot for a heavy task against a real synthetic repository, proving the assembled plan carries no placeholder markers and at least one step is grounded in concrete repo evidence -- the existing 6.1 coverage in this file only exercised the grounding helpers directly, not the whole seven-stage pipeline the way `baton plan` calls it. - tests/manager/test_context_bundles.py: the two distinct phantom- knowledge-pack diagnostics added in 6.3 (confirmed missing from the registry vs. present but never selected for this plan) plus a control case proving neither fires for a normally-selected pack. - tests/knowledge/test_telemetry_production_wiring.py: drives ExecutionEngine.record_step_result's dispatch-outcome wiring (added in 6.3) through the real production call site rather than only the isolated KnowledgeTelemetryStore-level coverage already in tests/knowledge/test_lifecycle_telemetry.py -- complete correlates 1.0, failed correlates 0.0, a non-terminal status leaves outcome NULL, and no knowledge_resolver at all is a safe no-op. Multi-amend artifact versioning, injected-failure rollback, and cross-sidecar integrity already had solid coverage from 6.3's tests/manager/test_rebuild.py -- not duplicated here.

honor gate_scope in archetype builders; exempt explicit phase overrides from auto-routing checks Three independent latent bugs (all predating phase 6, confirmed by running the same failing tests against the end-of-phase-5 commit) were surfaced by this phase's gate command: - RiskStage._ensure_safety_roster only extended classified_phases with a Review/Audit slot for an injected auditor/code-reviewer when draft.classified_phases was already a concrete list. When it was None (the common case -- DecompositionStage falls through to default_phases(inferred_type, ...) instead), an auto-injected auditor had nowhere to land, got force-assigned into the Implement phase, and ValidationStage's agent_phase_mismatch hard gate then rejected the whole plan. Fixed by materializing the same default phase-name template (rules/phase_templates.PHASE_NAMES) RiskStage would otherwise fall through to, whenever DecompositionStage will actually consult classified_phases for this draft (no explicit phases/subtask_data, phased archetype), so the Review/Audit-slot correction has a concrete base to extend. - ValidationStage's PHASE_BLOCKED_ROLES check (bd-0e36: guards against the planner's own auto-routing landing an architect on Implement) did not distinguish auto-routed steps from a caller's explicit phases=[{"name":..., "agents":[...]}] override, re-rejecting the very choice RosterStage/EnrichmentStage already agreed to preserve (TestEnrichmentStageExplicitPhasesGuard). Scoped the check to skip only the exact (phase name, agent) pairs the caller explicitly wrote, so an empty-agents dict (which still gets auto-routed via assign_agents_to_phases) keeps the full check. - DecompositionStage._build_direct_phases / _build_investigative_phases hardcoded `PlanGate(command="pytest --tb=short -q")` on the Implement/Fix phases, which meant EnrichmentStage._apply_gates (the only place gate_scope/stack-aware defaults are computed) skipped those phases entirely (`if phase.gate is None`). full/smoke gate_scope requests on DIRECT/INVESTIGATIVE-archetype plans were silently ignored.

Add a new manager-mode PMO API (agent_baton/api/routes/pmo_manager.py): read endpoints for charter, scope map, workstreams/phases, team blueprint, role cards, knowledge plan, scope contracts, context bundle metadata, reports, decision packets, published artifact version, and a version-consistency validation check -- all scoped to a single card_id, reading only through ManagerArtifactPaths' sanitized path builders (never a raw client-supplied path), with 404 for missing cards/artifacts vs 409 for a plan that isn't manager_mode. A narrow mutation endpoint (POST .../decisions/{id}/resolve) approves/denies a scope-expansion decision through ExecutionEngine.resolve_scope_expansion, the existing transactional rebuild-and-publish path. Promote agent_baton.core.manager.rebuild's plan-fingerprint digest to a public helper (plan_fingerprint) reused by the new validation endpoint, and add ContextManager.load_plan() so callers can load plan.json back into a MachinePlan through one conventional path.

Non-manager-mode plans get an explicit banner instead of a silent gap, and every manager-artifact fetch is independently fault-tolerant (Promise.allSettled) so one missing sidecar never blanks the rest of the workspace. The decision inbox resolves both the generic execution decision queue (APPROVAL/FEEDBACK/INTERACT, with a rationale field) and durable scope-expansion decisions (approve/deny with optional additional allowed paths), and reuses GateApprovalPanel for awaiting_human cards and the existing ExecutionProgress modal for the full step timeline and pause/resume/cancel/retry/skip controls. A new pure utils/executionStatus.ts derives a single paused/resuming/failed/ completed/... display status from column + error + local pause/resume action, documented against the execution-detail endpoint's actual (column-mirroring) status field so the UI never conflates a paused worker with a failed one. Extends pmo-ui/src/api/types.ts with the full Manager* response/domain shapes (charter, scope map, workstreams, team blueprint, role cards, knowledge plan, scope contracts, context bundles, decisions, version/validation) and the generic execution-decision-inbox and card-execution-detail types, plus matching client.ts methods -- all additive, no existing wire shapes changed. Evidence rows pair a reason/label with its path rather than surfacing a raw path alone (knowledge packs, context bundle must-read/reference entries), and scope contract / context bundle detail is lazy-loaded on expand via the per-step manager endpoints.
