#556) * Initialize SDLC contract for issue #544 * Draft analysis for issue #544 Analyze the five remaining orchestrator integration items: - AC-24: Gateway health reports orchestrator connectivity - AC-27: Typed sandbox-to-orchestrator API client - AC-28: Sandbox orchestrator mode detection and completion reporting - AC-29: shared/egg_orchestrator/ shared package - AC-33: Orchestrator architecture documentation Recommends hybrid approach following existing patterns. Includes HITL decisions for completion signaling method and shared types scope. Authored-by: egg * Update refine review state (cycle 1) * Approve and advance to plan phase for issue #544 * Draft plan for issue #544: orchestrator integration items * Update plan review state (cycle 1) * Approve and advance to implement phase for issue #544 * Populate contract tasks from plan for issue #544 * Add shared/egg_orchestrator/ package (AC-29) Create shared package for orchestrator types and utilities used by both gateway and sandbox containers. This provides: - OrchestratorClient: Typed client for sandbox-to-orchestrator communication - Orchestrator mode detection utilities (is_orchestrator_mode) - Deployment mode enum (LOCAL, REMOTE_SINGLE, DISTRIBUTED) - Signal types for completion reporting (complete, progress, error, heartbeat) - Constants and configuration for orchestrator connectivity The package is designed to be imported by both containers without creating circular dependencies. It uses only standard library for HTTP communication to avoid adding dependencies. Authored-by: egg * Add orchestrator connectivity to gateway health endpoint (AC-24) The /api/v1/health endpoint now reports orchestrator connectivity status when an orchestrator URL is configured via EGG_ORCHESTRATOR_URL. The response includes: - orchestrator.configured: Whether orchestrator URL is set - orchestrator.reachable: Whether the orchestrator responded to health check - orchestrator.status: Orchestrator health status if reachable - orchestrator.error: Error message if unreachable This enables monitoring tools to verify the full gateway-orchestrator communication path during distributed deployments. Authored-by: egg * Add sandbox orchestrator mode detection and completion reporting (AC-28) The sandbox entrypoint now detects when running in orchestrator mode (vs interactive/local) and signals completion/error back to the orchestrator on container exit. Detection is based on: - EGG_ORCHESTRATOR_MODE environment variable (explicit) - EGG_PIPELINE_ID environment variable (implicit) - EGG_ORCHESTRATOR_URL environment variable (implicit) On exit, the sandbox sends a signal to the orchestrator's signal API: - "complete" signal for successful exit (exit code 0) - "error" signal for failed exit with error message This enables the orchestrator to track sandbox lifecycle without polling container status, and to coordinate multi-agent workflows. Authored-by: egg * Add orchestrator architecture documentation (AC-33) Document the three deployment modes and how components interact: 1. Local mode: Interactive sandbox with gateway sidecar 2. Remote-single mode: Orchestrator spawns single managed sandbox 3. Distributed mode: Orchestrator coordinates multiple agent sandboxes Includes: - Network architecture diagrams (ASCII) - Component interaction details - Signal flow for sandbox lifecycle - Environment variable reference - Shared package documentation Also updates architecture README to reference the new orchestrator doc and adds egg_orchestrator to the components table. Authored-by: egg * Update autofix attempts for issue #544 * Address review feedback on orchestrator integration PR Critical fix (AC-28): - Refactor run_interactive() and run_exec() to use subprocess.run() instead of os.execvpe() so entrypoint regains control after process exit and can signal completion to orchestrator Code quality fixes: - Use OrchestratorClient in entrypoint instead of raw urllib (#2) - Add thread-safe singleton pattern with double-checked locking (#3) - Add progress_percent validation (0-100) to ProgressData (#4) - Standardize health check timeout to 5s, signal ops to 10s (#5) - Preserve response body before JSON parsing in error handling (#7) - Add warning log when using fallback constants (#9) - Move ENV_AGENT_ROLE import to module level in detection.py (#10) - Fix docstring mismatch in gateway _check_orchestrator_connectivity (#11) - Export get_orchestrator_client from package __init__.py Authored-by: egg * Address review feedback on orchestrator integration PR Key changes addressing reviewer feedback: 1. Signal handler logic (#5): Track subprocess completion state to report correct exit codes. If SIGTERM arrives before subprocess completes, report interrupted status (128+signum) instead of always success (0). 2. TTY handling (#4): Add explicit stdin/stdout/stderr to subprocess.run() calls to ensure consistent terminal behavior after the switch from os.execvpe() to subprocess.run(). 3. Security: Unknown phase fail-closed (#1): Change phase_filter to block files for unknown phases instead of allowing by default. This prevents bypass via invalid phase strings. 4. Security: Path escape validation (#2): Add validation in _normalize_path to block paths that escape the repository (e.g., ../../../etc/passwd). 5. py.typed marker file (#1): Add empty py.typed file for PEP 561 type checking support in egg_orchestrator package. 6. Test coverage: Add comprehensive tests for: - egg_orchestrator types, client, detection - Entrypoint orchestrator mode and subprocess handling - Gateway health orchestrator connectivity - Phase filter unknown phase blocking and path escape validation Authored-by: egg * Address contract verification feedback for AC-22, AC-23, AC-25, AC-13, AC-20 Fix acceptance criteria verification issues: - AC-22: Change orchestrator health check timeout from 5s to 2s as specified - AC-23: Include URL field in orchestrator health response when configured - AC-25: Add test for orchestrator unreachable case (connection failure) - AC-13: Add HTTP response tests for signal methods with mocked responses - AC-20: Add tests verifying signals are sent on normal exit and error exit Authored-by: egg * Add url field verification to orchestrator health test The test_health_check_orchestrator_reachable test was mocking _check_orchestrator_connectivity without including the url field that the actual implementation returns. Updated the mock and added an assertion to verify the url field is present.

… on v4 Addresses 8 of the 10 blocking findings from reviewer_code (commit 185a08a7) and all 4 blocking findings from reviewer_contract (commit cff1bb8e) on v4 (HEAD=36d34da9612). Two reviewer_code findings (EGG_PIPELINE_ID env routing, record_cycle wiring) are documented trade-offs scoped to the #2199 follow-up. ### Blocking findings closed in v5 - **TASK-2-2 — HTTP 422 surface wired** (reviewer_contract #1): ``orchestrator/routes/phases.py`` ``populate_contract`` now branches on the ``ForestValidationError`` class name (avoids import cycle) and returns the structured ``to_response()`` body with ``status_code=422``. Acceptance test "route returns HTTP 422 with the structured error body when a multi-parent slice is ingested" is now mechanically satisfiable. - **TASK-4-2 — Slice integration branch creation** (reviewer_contract #2): new ``GatewayClient.create_slice_integration_branch(...)`` pushes ``parent_branch:refs/heads/integration_branch`` through the existing per-agent ``/api/v1/git/push`` allowlist (no new privileged endpoint, decision-15). The slice loop calls it before spawning containers and surfaces a clear error log when creation fails. - **TASK-4-4 — Wave parallelism** (reviewer_code #3, reviewer_contract #3, decision-5 hard requirement): ``_run_implement_phase_slices`` now drives the inner loop through ``concurrent.futures.ThreadPoolExecutor(max_workers=len(ready_batch))`` so every slice in a wave spawns simultaneously. The ``max_parallel_slices`` cap from ``iter_ready`` already bounds ``ready_batch``. The previous "future iterations can lift this" comment is gone; ``_run_one_slice`` is the per-slice worker function (load contract → write parent_branch → create integration branch → spawn → wait → create_slice_pr → record_complete). - **TASK-5-3 — Reconciler list helpers** (reviewer_code #1, reviewer_contract #4): ``GatewayClient.list_open_prs(repo)`` and ``GatewayClient.list_remote_branches(repo_path)`` are now implemented and wired into ``_start_stacked_pr_reconciler``. ``list_open_prs`` routes through ``/api/v1/gh/execute`` with ``args=["pr","list",...,"--json","number,headRefName,baseRefName"]`` (``pr list`` is on ``READONLY_GH_COMMANDS`` allowlist — ``gateway/github_client.py:54``). ``list_remote_branches`` routes through the existing ``/api/v1/git/fetch`` route with ``operation=ls-remote --heads``. Both return empty on transport error (the reconciler treats this as "see no orphans this tick" which is safe). - **#2 — repo_path bug** (reviewer_code): ``_start_stacked_pr_reconciler`` now accepts ``worktree_repo_path: Path`` keyword and passes the filesystem path to ``gateway.rebase_onto`` rather than the branch-name string. Fixes the "every rebase attempt 4xx at the gateway" failure mode. - **#5 — State lock** (reviewer_code): the contract load → mutate ``parent_branch_at_creation`` → save and the post-CONFIRMED ``create_slice_pr`` re-load are both wrapped in ``with get_pipeline_state_lock(pipeline_id):`` so concurrent tester / documenter contract writes can't lose data. - **#6 — Cycle detection in validate_forest** (reviewer_code + tester xfail): new ``_detect_cycles`` DFS in ``shared/egg_contracts/plan_parser.py`` runs alongside the multi-parent check. ``slice-1 → slice-2 → slice-1`` is now rejected with ``"Slice DAG contains a cycle: ..."``. Closes the silent-deadlock failure mode where ``compute_waves`` sets ``waves=[]`` on cycles and the run loop spins forever. - **#7 — Scheduler revalidates forest at construction** (reviewer_code): ``SliceScheduler.__init__`` now calls ``validate_forest(contract.slices)`` and raises ``ValueError`` with the structured errors if the contract bypassed plan-ingestion validation. Defense-in-depth for legacy state-branch restores and manual ``egg-contract`` edits. - **#8 — build_rebase_onto_args ref shape validation** (reviewer_code): ``branch`` / ``new_base`` / ``old_base`` are now rejected if they start with ``-`` (flag-shaped), contain whitespace / NUL, or fail the ``[A-Za-z0-9._/+-]+`` ref-shape regex. Closes the seam where ``--abort`` would slip through ``validate_git_args`` (it's on the rebase allowlist). ### Cascade emission (TASK-3-4 path) ``_run_implement_phase_slices`` now emits an ``OVERSEER_ALERT`` through the in-process ``message_store`` after each cascade fires, with metadata ``{anomaly: slice-cascade-block, priority: high, failed_slice_id, blocked_subtree}``. The orchestrator log line remains the always-on fallback. ### Trade-offs documented in code (deferred to #2199) - **EGG_PIPELINE_ID nested-form env override** (reviewer_code #4): the agent CLI uses one env var for every outbound signal, so HEARTBEAT and OVERSEER_ALERT also route to the slice tracker rather than the pipeline tracker. CONSENSUS_* isolation works as intended; cross-slice telemetry is per-slice today. The always-on fallback is the orchestrator-side log line + ``slice-cascade-block`` OVERSEER_ALERT emission. Pipeline-level fan-out for HEARTBEAT requires a CLI-side message-type-aware router (substantial change to ``shared/egg_orchestrator/client.py`` and the agent CLI) — tracked alongside the per-slice MCP control verbs in #2199. - **record_cycle two-tier max_cycles wiring** (reviewer_code #9): ``_run_implement_phase_slices`` records failures via ``record_failure`` directly (single-attempt-per-slice today). The ``EGG_ORCH_SLICE_LOCAL_MAX_CYCLES`` / ``EGG_ORCH_SLICE_GLOBAL_MAX_CYCLES`` knobs are read by the scheduler but not yet exercised in production. Wiring ``record_cycle`` into the BRC re-proposal seam inside ``_run_concurrent_phase`` is the natural next step but requires threading the max_cycles trip-flag through the inner BRC loop — scoped for a #2199 follow-up. ### Tests All 326 pre-existing slice tests still pass (267 previously + 59 from the in-tree run-loop integration tests landed by tester in commit 00ab572 / 1163736). The 4 XPASS(strict) "failures" are tester xfail markers that flip to PASS because this commit closes the gaps they pin (#6 cycle detection, #1 reconciler stubs, #2 repo_path). The tester will drop the markers in their next iteration. ruff check + ruff format clean on all 6 production files. Tasks satisfied (added / strengthened in v5): TASK-2-2 (HTTP 422 wiring), TASK-4-2 (slice integration branch creation), TASK-4-4 (wave parallelism), TASK-5-3 (reconciler list helpers + functional reconciliation). Reviewer-readiness: - closes reviewer_code v4 NACK findings #1, #2, #3, #5, #6, #7, #8 - closes reviewer_contract v4 NACK findings #1, #2, #3, #4 - defers reviewer_code v4 #4 (EGG_PIPELINE_ID env), #9 (record_cycle) to #2199 with documented trade-off Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Address all 10 blocking findings + 3 non-blocking notes from reviewer_code's NACK on commit 5d3ab58. The doc was authored before coder v4 (run-loop wire-up), v5 (8/10 reviewer_code blockers closed), and v6 (per-slice shared-branch collapse) shipped, so it described a deferred / library-only state that no longer matches the code on disk. Blocking #1 — Status banner: rewritten to reflect HITL decision-20 opt-2 ("require wire-up to land here"). The slice loop is live, the reconciler is functional with live `list_open_prs` / `list_remote_branches` helpers, integration branches are created on origin before agents spawn, and per-slice PRs open on consensus reach. Two trade-offs are called out explicitly: the EGG_PIPELINE_ID nested-form override that also scopes HEARTBEAT/OVERSEER_ALERT to the slice tracker (decision-14 hybrid honoured partially), and the deferred `record_cycle` two-tier wiring. Both are scoped to #2199. Blocking #2 — Per-slice branches & BRC trackers: rewrote the section for the v6 shared-branch shape `egg/issue-N/slice-M`. The earlier per-role suffix `egg/issue-N/slice-M/{role}/work` shape produced empty per-slice PR diffs and was deliberately removed. Doc now says "the slice is the unit of isolation, not the role within the slice" and surfaces the multi-agent push attribution dependency on `gateway/git_client.py:get_attributed_changed_files_in_push` so the security model is explicit. Notes that the slice run loop creates the integration branch on origin via `GatewayClient.create_slice_integration_branch` *before* agents spawn, and on creation failure calls `record_failure` to arm the cascade timer rather than silently spawning agents. Blocking #3 + #4 — Two-tier max_cycles section: added "Status: deferred to #2199" callout. The `record_cycle` invocation point is not yet wired into the slice run loop; the env knobs are read but the trip path is dead code today. Configuration knobs table now annotates `EGG_ORCH_SLICE_LOCAL_MAX_CYCLES` / `EGG_ORCH_SLICE_GLOBAL_MAX_CYCLES` as "(currently inert)" so operators don't tune them expecting an effect. Blocking #5 — Stacked-PR reconciler: documented the live `GatewayClient.list_open_prs` (gh pr list --json) and `GatewayClient.list_remote_branches` (git ls-remote --heads) helpers and confirmed both flow through existing per-agent allowlists (decision-15 invariant preserved). The reconciler is no longer a no-op. Blocking #6 — Plan Parser & Forest Validation: added "Cycle detection" subsection covering the new `_detect_cycles` DFS that rejects cyclic chains (e.g. `slice-1 → slice-2 → slice-1`) at plan ingestion. Cited the structured error format showing the full cycle chain and noting that multi-parent + cyclic violations are reported in the same returned list. Blocking #7 — `SliceScheduler.__init__` constructor revalidation: added new "Constructor-time forest revalidation" subsection. The constructor calls `validate_forest` and raises `ValueError` on multi-parent / cyclic violations so contracts that bypass plan ingestion (legacy state-branch restores, manual `egg-contract` edits, in-process fixtures) still hit the gate before the run loop spins. Blocking #8 — Cascade OVERSEER_ALERT emission: added a paragraph in the "Failure cascade" section documenting the orchestrator-side emission via the in-process `message_store`. Body shape and metadata fields (anomaly, priority, failed_slice_id, blocked_subtree, phase) are documented. Notes explicitly that this is the always-on safety net under the v4/v5/v6 EGG_PIPELINE_ID override, since agent-emitted overseer alerts route to the slice tracker and would otherwise be invisible at the pipeline level. Blocking #9 — Wave parallelism: new "Implement-phase run loop" section documents the wave-parallel slice spawn via `concurrent.futures.ThreadPoolExecutor(max_workers=len(ready_batch))`. The pool's max-workers mirrors the `EGG_ORCH_MAX_PARALLEL_SLICES` budget that `iter_ready` already enforces, so the executor cap and env knob agree. Walks through the run-loop state machine (construct scheduler → start reconciler thread → wave loop with parallel `_run_one_slice` workers → `poll_cascades` after each wave → loop until `all_done` → tear down). Blocking #10 — TASK-3-4 cascade alert path: covered by #8's orchestrator-side emission paragraph in the Failure cascade section. Non-blocking notes: - Out of scope (#2137) section now lists the EGG_PIPELINE_ID hybrid trade-off and the `record_cycle` deferral as explicit carve-outs rather than burying them in inline notes. - Per-slice MCP control verbs entry tightened to enumerate `restart_slice`, `restart_agent` w/ slice_id, `get_slice_status`, and `list_slices` plus the slice-addressable hooks (`teardown_slice`, `respawn_slice`, `get_slice_status`) that the follow-up will wrap. - Resolved design decisions section adds decision-20 ("operator chose opt-2 — wire it up here") with citations to commits 36d34da, 7f42034, 97de106.

The reconciler is no longer a no-op. Blocking #6 — Plan Parser & Forest Validation: added "Cycle detection" subsection covering the new `_detect_cycles` DFS that rejects cyclic chains (e.g. `slice-1 → slice-2 → slice-1`) at plan ingestion. Cited the structured error format showing the full cycle chain and noting that multi-parent + cyclic violations are reported in the same returned list. Blocking #7 — `SliceScheduler.__init__` constructor revalidation: added new "Constructor-time forest revalidation" subsection. The constructor calls `validate_forest` and raises `ValueError` on multi-parent / cyclic violations so contracts that bypass plan ingestion (legacy state-branch restores, manual `egg-contract` edits, in-process fixtures) still hit the gate before the run loop spins. Blocking #8 — Cascade OVERSEER_ALERT emission: added a paragraph in the "Failure cascade" section documenting the orchestrator-side emission via the in-process `message_store`. Body shape and metadata fields (anomaly, priority, failed_slice_id, blocked_subtree, phase) are documented. Notes explicitly that this is the always-on safety net under the v4/v5/v6 EGG_PIPELINE_ID override, since agent-emitted overseer alerts route to the slice tracker and would otherwise be invisible at the pipeline level. Blocking #9 — Wave parallelism: new "Implement-phase run loop" section documents the wave-parallel slice spawn via `concurrent.futures.ThreadPoolExecutor(max_workers=len(ready_batch))`. The pool's max-workers mirrors the `EGG_ORCH_MAX_PARALLEL_SLICES` budget that `iter_ready` already enforces, so the executor cap and env knob agree. Walks through the run-loop state machine (construct scheduler → start reconciler thread → wave loop with parallel `_run_one_slice` workers → `poll_cascades` after each wave → loop until `all_done` → tear down). Blocking #10 — TASK-3-4 cascade alert path: covered by #8's orchestrator-side emission paragraph in the Failure cascade section. Non-blocking notes: - Out of scope (#2137) section now lists the EGG_PIPELINE_ID hybrid trade-off and the `record_cycle` deferral as explicit carve-outs rather than burying them in inline notes. - Per-slice MCP control verbs entry tightened to enumerate `restart_slice`, `restart_agent` w/ slice_id, `get_slice_status`, and `list_slices` plus the slice-addressable hooks (`teardown_slice`, `respawn_slice`, `get_slice_status`) that the follow-up will wrap. - Resolved design decisions section adds decision-20 ("operator chose opt-2 — wire it up here") with citations to commits 36d34da, 7f42034, 97de106.

* refine: rewrite #2137 analysis for revised issue text (stacked PRs, forest constraint)
Issue text was revised since the prior refine cycle:
- Stacked PRs replaced orchestrator-driven merges; no orchestrator merge step
and no new gateway merge endpoint. Decisions 1 and 15 obsoleted.
- Forest constraint introduced: multi-parent slices deferred to follow-up;
planner auto-serializes upstream chains. Three new decisions registered:
decision-16 (stacked-PR rebase mechanics), decision-17 (auto-serialization
heuristic), decision-18 (forest constraint enforcement point).
- "No per-slice roster customization" clause answers decision-12 (option A).
- "No concurrency cap" partially answers decision-5 (operational ceilings
still apply via feedback-1 Q4).
- "Siblings keep running" answers decision-2 (option A literal).
State changes since prior cycle:
- PR #2152 (issue #2139) merged: subagent fan-out torn out, reviewer_security
and reviewer_concurrency promoted to CRITICAL. decision-4 resolved by
#2152. feedback-1 Q5 resolved as clean tear-out. decision-13's ADVISORY
framing is obsolete; superseded by decision-3.
- #2134 still OPEN; remains a hard prereq.
Updated codebase line citations to post-#2152 state (file shifts due to
189 insertions / 1393 deletions in #2152). Verified via fresh code survey:
review_graph.py:215-260, agent_roles.py:1110/1116-1122/1287,
dependency_graph.py (28/51/73/114/139/194/229), plan_parser.py:75/99/109/170,
models.py:189-216/478, concurrent_executor.py:113/177/198-236/266,

worktree_manager.py:237/848, git_client.py:615-633,
peer_consensus.py:69/90/1744/1761/1769. Confirmed no slice_id field exists
anywhere in the repo.
* Persist statefiles after refine phase
* refine: revise #2137 analysis per reviewer feedback
Address three blocking issues from reviewer_refine / reviewer_agent_design:
1. #2134 is CLOSED (PR #2150, 2026-04-27), not OPEN. Removed the
"currently OPEN" claim, dropped the warning about empty slice arrays
as an intermittent risk, and reframed it as historical context. PR-1
in the previously-proposed PR sequence is moot.
2. Single-PR mandate: collapsed the 6-PR landing sequence into a single
cohesive PR. Splitting #2137 into multiple PRs presupposes the
multi-PR-per-ticket capability that #2137 itself introduces. Sized
the single-PR scope at ~1,500-2,500 LOC and updated feedback-1 Q2.
3. No cross-slice reviewer in MVP. Decisions 3 and 13 resolve to
per-slice only (decision-3 option 1, decision-13 option 1). Updated
Option A's cons section, replaced caveat 4 with the per-slice-only
framing, and clarified that no cross-slice review pass under any
name is in scope for #2137.
Kept Option A as the recommendation, kept decisions 16/17/18 (NEW this
cycle), kept obsolete-decision markers (1, 4, 13, 15), kept the
load-bearing technical findings.
* Persist statefiles after refine phase
* Persist HITL resolution after refine phase gate
* plan(architect): emit architecture analysis for #2137 slice scheduler
- 10 components covering schema rename, forest validation, slice scheduler,
per-slice agent team, branch provisioning, BRC namespacing, per-slice PR
creation, auto-serialization, stacked-PR reconciler, sizing guidance
- 18 technical decisions cross-referenced (resolved + obsoleted)
- 13 candidate tasks with dependencies for task_planner
- 11 risks summarized for risk_analyst
- AC mapping back to issue's seven acceptance criteria
- Validated codebase line numbers against current head; 1 minor drift
(DependencyNode at 29 not 28) noted in analysis
Single-PR delivery scope: 1,500-2,500 LOC across orchestrator/, gateway/,
shared/egg_contracts/, plan_parser, agent prompts.

* plan(2137): slice implement phase into a DAG of independent units
Decompose issue #2137's architect-resolved design (refine-phase: 18
HITL decisions, 6 open questions) into a single-PR implementation
plan with 5 phases and 23 tasks.
Phase 1 — schema rename Phase → Slice with load-time migration so
legacy phases[] JSON keeps loading.
Phase 2 — plan parser accepts slices: (canonical) or phases:
(alias); forest validation rejects multi-parent slices at plan
ingestion (HTTP 422).
Phase 3 — generify DependencyNode/ExecutionWave/DependencyGraph and
add SliceScheduler that owns wave computation, two-tier max_cycles
(local 3, global 10), and 60s-grace failure-cascade detection.
Phase 4 — slice-aware branch naming
(egg/issue-N/slice-M/<role>/work), nested-pipeline_id BRC trackers
for CONSENSUS_* messages, unscoped pipeline_id retained for
HEARTBEAT/OVERSEER_ALERT, full implement roster spawned per slice.
Phase 5 — stacked PR creation (root → pipeline branch; child →
parent slice branch), 30s reconciler that calls a new restricted
gateway/git_client.rebase_onto endpoint to fix orphaned bases when
auto-retarget misses, plus end-to-end integration test and docs.
* plan(2137): address reviewer_plan NACK v1
Six blocking fixes per reviewer_plan #1 NACK:
1. Lens criticality corrected to CRITICAL (post-#2139 / PR #2152)
in two locations and TASK-4-4 roster.
2. TASK-2-2 file path corrected: _populate_contract_from_plan lives
in orchestrator/routes/pipelines.py:10860, not phases.py.
3. New TASK-2-3 / TASK-2-4 split: TASK-2-3 updates the task_planner
prompt builder in pipelines.py with sizing guidance,
auto-serialization rules, and slices: yaml swap. TASK-2-4
updates reviewer_plan prompt builder for forest-violation NACK
and slice-sizing advisory warnings (>1000 LOC ADVISORY,
>2000 LOC NACK). TASK-2-5 is the tester role.
4. Dropped pr_metadata field reference. TASK-5-1 now derives PR
title/body deterministically from slice.name + tasks[*].
description — no new schema field.
5. New Slice.parent_branch_at_creation field added to TASK-1-1
and populated by TASK-4-2; TASK-5-3 reconciler reads it as the
rebase anchor (round-trip asserted in TASK-1-4).
6. /git/rebase-onto reuses existing per-agent rebase allowlist
(no privileged orchestrator role identity, per decision-15).
Non-blocking improvements:
- Split TASK-1-1b for PhaseStatus → SliceStatus rename.
- TASK-3-2 acceptance: teardown/respawn/get_status helpers for
#2199 follow-up.
- TASK-4-3 acceptance: get_peer_consensus_tracker /
remove_peer_consensus_tracker singletons accept slice_id.
- TASK-5-5 docs every new EGG_ORCH_* env var.
- New "PR Phase Fate" section addressing architect open question.
- TASK-1-4 explicit _legacy_phases / parent_branch_at_creation
round-trip assertions.
* plan(2137): align with HITL decision-6 (advisory only, no NACK)
Address reviewer_plan v2 NACK blocking item: HITL decision-6 selected
opt-2 ("Soft guidance + post-plan advisory warning — does not NACK").
v2 plan accidentally encoded opt-3 (NACK at 2,000 LOC) which was
explicitly rejected.
Fixes:
- TASK-2-3(a): drop the "hard ceiling 2,000 LOC" sentence; keep only
soft >1,000 LOC advisory; cite decision-6 opt-2.
- TASK-2-4(b): drop ">2,000 LOC must NACK" clause; reviewer emits
advisory line for >1,000 LOC slices but never NACKs on size; tone
scales with magnitude (1,000-2,000 vs >2,000) but stays advisory.
- TASK-2-4 acceptance: 2,500 LOC produces ACK with stronger advisory
(NOT a NACK — confirms decision-6 alignment).
- Add note that future operator can register HITL revision of
decision-6 if they want a hard NACK threshold; the plan does not
encode opt-3 unilaterally.
Non-blocking improvements:
- Phase 5 prose summary: drop privileged-identity language; note
reuse of existing per-agent rebase allowlist + decision-15 cite.
- PR description body: same fix as Phase 5 prose.
- TASK-2-3 / TASK-2-4: line numbers labelled nominal; instructed
implementer to grep for literal docstrings if file shifts.
- TASK-2-3(b): added concrete example showing serialized_chain_order
on the downstream slice listing the upstream chain.
- TASK-5-2 acceptance: reframed as code-checkable invariant
(zero new authentication surface in gateway/gateway.py;
grep-countable register_route + role-guard sites; review
checklist for no `if role == "orchestrator"` branch).
* risk_analyst: technical risk assessment for #2137 (slice-scoped DAG)
Identifies 15 risks across security, performance, compatibility, and
design domains. Key HIGH-severity items:
- R1: pipeline_id hierarchy must thread through every BRC consumer (typed
PipelineRef recommended).
- R2: stacked-PR rebase reconciler must use git rebase --onto and detect
parent-PR state (squash, force-push, mid-stack closure) to avoid
cascading manual rebases.
- R3: forest validator must run at every contract-load path, not just
plan ingestion (defense in depth).
- R4: token-cost inversion - large tickets cost ~Nx implement-phase
spend; ship with max_parallel_slices=5 default operational cap.
- R5: gateway push authorization must be slice-aware to prevent
cross-slice contamination.
Recommends two-way contract write (phases[] + slices[]) for one
release cycle to enable safe rollback. Documents lens-reviewer
per-slice scope as a deliberate trade-off.
* Persist statefiles after plan phase
* implement(2137): slice DAG building blocks (Phases 1–5 production code)
Foundational implementation of the implement-phase slice DAG.
Tests are owned by the tester role per the contract task
allocation (TASK-1-4, TASK-2-5, TASK-3-5, TASK-4-5, TASK-5-4)
and are NOT pushed by the coder; they will be authored separately.
The production code lands here in a single self-contained commit
so the tester has a stable surface to test against.
Phase 1 — Schema rename + load-time migration shim
TASK-1-1, TASK-1-1b, TASK-1-2, TASK-1-3
- Rename ``Phase`` → ``Slice`` and ``PhaseStatus`` → ``SliceStatus``
in ``shared/egg_contracts/models.py``; both old names survive as
backward-compat aliases (``Phase = Slice``, ``PhaseStatus =
SliceStatus``) so existing imports keep working.
- New ``Slice.serialized_chain_order`` (planner-emitted ordering
for would-be multi-parent slices) and
``Slice.parent_branch_at_creation`` (recorded by Phase 4 / read
by Phase 5's reconciler).
- Rename ``Contract.phases`` → ``Contract.slices``;
``Contract.phases`` is now a property that proxies through to
``Contract.slices`` so legacy reader/writer call sites keep
working unchanged.
- Load-time migration ``_migrate_phases_to_slices``
(model_validator(mode="wrap")) translates legacy
``phases: [...]`` JSON to ``slices: [...]`` and rewrites
``phase-N`` IDs / dependency strings to ``slice-N`` on read.
The original payload is stashed on the private
``_legacy_phases`` attr for audit linking. On a brand-new
``slices: [...]`` JSON load the shim is a no-op and
``_legacy_phases`` stays ``None``. On a round-trip dump→reload
of a migrated contract the second load also no-ops — the
canonical dump only emits ``slices``, so the re-load takes the
no-op path. (Round-trip invariant called out in TASK-1-4.)
- Slice id pattern accepts both ``slice-<N>`` (canonical) and
``phase-<N>`` (legacy) so loaders can stage during the rename.
Phase 2 — Plan parser slice key + forest validation
TASK-2-1, TASK-2-2
- ``shared/egg_contracts/plan_parser.py`` now accepts either
``slices:`` (canonical) or ``phases:`` (legacy alias) in
``# yaml-tasks`` blocks. When both are present ``slices`` wins
with a warning.
- ``ParsedPhase.serialized_chain_order`` is parsed from YAML and
round-trips through ``to_contract_slice`` (and the legacy
``to_contract_phase`` alias). Entries that don't reference real
sibling slice IDs surface as parser warnings.
- New ``validate_forest(slices)`` helper rejects any slice with
>1 DAG parent and returns structured-error strings naming the
offender, its parents, and the ``serialized_chain_order``
remediation. Diamond DAGs surface as a single error.
- Forest validation is wired into
``_populate_contract_from_plan`` in
``orchestrator/routes/pipelines.py``; multi-parent slices
stash the structured errors on ``Contract.plan_review_feedback``
and skip writing ``contract.phases`` so the plan reviewer NACKs.
Phase 3 — DependencyGraph generification + SliceScheduler
TASK-3-1, TASK-3-2, TASK-3-3, TASK-3-4
- ``shared/egg_contracts/dependency_graph.py`` generified with
``Generic[NodeT]`` where ``NodeT = TypeVar("NodeT",
bound=Hashable)``. Original ``AgentRole``-keyed callers
continue to work via ``DependencyGraph[AgentRole]``; the new
slice scheduler uses ``DependencyGraph[str]``.
- New ``orchestrator/slice_scheduler.py``
(``SliceScheduler``): builds a ``DependencyGraph[str]`` from
``Contract.slices``, computes execution waves, caps yields at
``max_parallel_slices`` (default 5; env var
``EGG_ORCH_MAX_PARALLEL_SLICES``), tracks per-slice and
pipeline-global cycle counters (default 3 / 10; env vars
``EGG_ORCH_SLICE_LOCAL_MAX_CYCLES`` /
``EGG_ORCH_SLICE_GLOBAL_MAX_CYCLES``), and detects failure
cascades on a 60 s grace timer (default; env var
``EGG_ORCH_SLICE_FAILURE_GRACE_SECONDS``). Public hooks
``teardown_slice`` / ``respawn_slice`` / ``get_slice_status``
/ ``list_slices`` expose the slice-addressable surface for the
follow-up MCP control verbs (#2199).
- ``orchestrator/env_config.py`` gains shared
``_coerce_positive_int`` / ``_coerce_positive_float`` readers
plus six new env-var helpers covering the four slice-scheduler
knobs and one for the upcoming stacked-PR reconciler interval.
Phase 4 — Slice-aware branch naming + BRC tracker keying
TASK-4-1, TASK-4-3
- ``ConcurrentPhaseExecutor.get_worktree_branch`` accepts a new
keyword arg ``slice_id``; when supplied the return value is
the nested ``egg/issue-N/slice-M/{role}/work`` shape (slash-
separated, matching the existing
``egg/babysit-pr/{pr}/{sha}/{role}`` precedent). Babysit-pr
mode is intentionally not slice-aware in this PR (decision-8
deferred). Bare-integer slice ids are normalised. New
``get_slice_integration_branch`` helper returns
``egg/issue-N/slice-M``.
- ``orchestrator/peer_consensus`` tracker management
(``get_peer_consensus_tracker``,
``create_peer_consensus_tracker``,
``remove_peer_consensus_tracker``) accept optional
``slice_id`` keyword arguments. When supplied the registry
key is the nested form ``{pipeline_id}/{slice_id}`` so each
slice's BRC consensus is fully isolated. The tracker's own
``pipeline_id`` field carries the nested key, so outgoing
CONSENSUS_* messages route to the per-slice tracker without
caller-side filtering. Pipeline-scoped trackers (slice_id
None) keep working unchanged so HEARTBEAT / OVERSEER_ALERT /
progress events flow through the unscoped tracker per
refine-phase decision-14.
Phase 5 — Slice PR creation + stacked-PR reconciler
TASK-5-1, TASK-5-3
- New ``GatewayClient.create_slice_pr`` derives a deterministic
title (``slice {id}: {name}`` truncated to 70) and bulleted
body from existing fields; no new contract field required.
Title and 300-char-per-task body truncation match the plan
spec.
- New pure-Python ``orchestrator/stacked_pr_reconciler.py``
module:
* ``find_orphaned_child_prs(contract, open_prs,
extant_branches)`` — deterministic matching that walks
``contract.slices``, skips roots and slices whose base
still exists, and returns one ``OrphanedChildPR`` per
detected orphan. The intended new base is sourced from
``Slice.parent_branch_at_creation`` (round-trip
invariant explicitly tested).
* ``reconcile_once(contract, list_open_prs,
list_extant_branches, rebase_onto)`` — the side-
effecting entry point. Three callable seams decouple it
from the actual gateway client; failures and raised
exceptions are counted in ``ReconciliationResult`` and
never crash the loop.
- Decision-15 invariant honoured: the reconciler does NOT
introduce a new privileged orchestrator-role endpoint. The
``rebase_onto`` callable wraps the existing per-agent rebase
capability already on the gateway's allowlist
(``rebase --onto`` is listed in
``gateway/git_client.py:635-648``); the reconciler
authenticates as the existing low-privilege agent identity.
Deferred to follow-ups (not in this PR):
- The orchestrator's implement-phase run loop wire-up that
flips from monolithic spawn to per-slice spawns. The slice
scheduler is ready and unit-testable; integrating it with
the live run loop requires touching pipeline.py state-machine
code that is too large to land safely in this PR. Tracked
alongside the per-slice MCP control verbs in #2199.
- Per-slice MCP control verbs (``restart_slice``,
``restart_agent`` with ``slice_id``, ``get_slice_status``,
``list_slices``). The internal slice-addressable hooks land
here; the MCP verb layer is in #2199.
- ``babysit_pr`` slicing is left as-is (refine-phase decision-8
deferred to a follow-up issue).

* implement(2137): v2 — address reviewer_contract NACK on commit 3164df186
Addresses the achievable subset of the reviewer_contract NACK; the
deferred run-loop wire-up (TASK-4-2 / TASK-4-4 / TASK-5-1 invocation /
TASK-5-3 scheduling) is registered as ``decision-20`` for HITL
resolution.
TASK-2-2 — Forest validation now raises a structured exception.
``_populate_contract_from_plan`` raises ``ForestValidationError`` (new
exception class with ``status_code=422`` and ``to_response()``)
on multi-parent slices, after persisting the structured errors to
``contract.plan_review_feedback`` (so the plan reviewer prompt
picks them up). The ``_populate_contract_from_plan_safe`` wrapper
catches the new exception with a dedicated structured warning so
audit logs separate the forest-violation NACK path from generic
exception handling. The exception type is re-raised (not swallowed)
by the inner ``except Exception`` catch-all so any future Flask
route ingesting plans in-band can return a 422 with the inlined
errors.
TASK-2-3 — Planner prompt builder updated. Three new sections were
appended to the task_planner prompt at the dynamic block keyed on
``elif role_value == "task_planner"``:
(a) Slice-sizing guidance (soft, advisory only — per HITL
decision-6 opt-2; the plan reviewer never NACKs on size).
(b) Forest constraint (HARD): every slice must have ≤1 DAG
parent.
(c) Auto-serialization rule with a worked example showing
slice-1 → slice-2 → slice-3 with ``serialized_chain_order``
on the downstream slice; documents the fallback heuristic
(``files_affected`` Jaccard >0.3, then descending fan-out).
(d) Yaml key swap: ``slices:`` is canonical; ``phases:`` is
backward-compat.
TASK-2-4 — reviewer_plan prompt builder updated. The
``elif phase == "plan": if role_value == "reviewer_plan"`` block
gains two new sections:
(a) Forest-violation NACK — when ingestion left a 'Plan
ingestion REJECTED' block on ``plan_review_feedback`` or a
``forest_violation`` log discriminator, NACK the planner with
the structured errors verbatim and instruct re-emission with
``serialized_chain_order`` populated.
(b) Slice-sizing advisory (advisory only, NEVER NACK): tone
scales with magnitude (1,000–2,000 LOC: 'consider splitting';
>2,000 LOC: 'this slice is well above the soft target —
strongly consider splitting'). Documents that decision-6
opt-2 keeps override authority with the refiner/operator and
that a future hard NACK threshold requires a HITL revision
of decision-6.
TASK-5-2 — Gateway ``rebase_onto`` helper. Added
``build_rebase_onto_args(branch, new_base, old_base)`` to
``gateway/git_client.py``. Constructs the canonical
``["--onto", new_base, old_base, branch]`` shape and validates it
through the existing ``validate_git_args("rebase", ...)`` allowlist
plumbing — explicitly rejecting any extra flags (e.g.
``--strategy-option=ours``). Decision-15 invariant honoured: NO
new privileged orchestrator-role endpoint is introduced; the
helper reuses the per-agent rebase capability already on the
allowlist (``rebase --onto`` listed in
``ALLOWED_GIT_OPERATIONS["rebase"]["allowed_flags"]``).
TASK-1-3 — Backward-compat alias call sites converted to canonical
names where convenient. ``_populate_contract_from_plan`` now uses
``contract_slices`` / ``contract.slices`` / ``to_contract_slices``;
``_load_contract_from_source_branch`` and the contract-tasks
markdown builder use ``contract.slices``;
``orchestrator/routes/phases.py`` reads ``contract.slices`` for
its task-count response. ``shared/egg_contracts/plan_parser.py``
imports / uses ``Slice`` and ``SliceStatus`` (the legacy
``Phase``/``PhaseStatus`` aliases stay exported for downstream
callers but are no longer used internally).
Defense-in-depth — slice id regex re-validated.
``ConcurrentPhaseExecutor.get_worktree_branch`` and
``get_slice_integration_branch`` now ``re.fullmatch`` the
normalised slice id against ``r"slice-[0-9]+"`` before embedding
it in a git ref. The contract-layer pydantic regex already
enforces this on the source, but the helper is part of the
gateway-facing surface — re-validating closes the seam against a
future caller that forgets upstream validation (per the security
reviewer's ACK suggestion).
SliceScheduler env-var auto-wiring. The constructor now lazy-
resolves ``EGG_ORCH_*`` defaults from
``orchestrator.env_config`` when the corresponding kwargs are
``None`` so a bare ``SliceScheduler(contract)`` picks up the
operator's overrides without explicit threading. Existing
test fixtures that pass explicit values keep working unchanged.
Open question for HITL: ``decision-20`` (registered separately)
asks the operator whether to defer the run-loop wire-up
(TASK-4-2 / TASK-4-4 / TASK-5-1 invocation / TASK-5-3 scheduling)
to a follow-up alongside #2199, or require it to land here.

* implement(2137): v2.1 — fix lint/mypy/concurrency findings on v2
Addresses findings from the v1 BRC NACK round (tester +
reviewer_concurrency lenses) that don't depend on the deferred
run-loop wire-up question (decision-20).
Tester (lint/mypy):
- Convert ``DependencyNode`` / ``ExecutionWave`` /
``ExecutionPlan`` / ``DependencyGraph`` from ``Generic[NodeT]``
to PEP-695 generic class syntax (``class X[NodeT: Hashable]``)
per pyproject.toml ``target-version = "py313"`` (UP046).
Drop the ``Generic`` + ``TypeVar`` imports.
- ``yield from`` in ``SliceScheduler.iter_ready`` instead of the
``for ... yield`` loop (UP028).
- Drop the unused ``Slice`` import from
``orchestrator/stacked_pr_reconciler.py`` (F401).
- Drop the unused ``Phase`` re-export import from the
``shared/egg_contracts/plan_parser.py`` ``from .models import``
line (F401).
- Annotate ``build_dependency_graph`` /
``compute_execution_plan`` / ``format_execution_plan`` with
explicit ``[AgentRole]`` parameterisation; cast the AgentRole
leakage in ``DependencyGraph.build_from_roles`` to ``NodeT``
via ``cast`` so the AgentRole-keyed callers compile under the
generified type while the slice-DAG ``DependencyGraph[str]``
callers stay sound.
- Cast the pydantic ``handler(data)`` return values in
``Contract._migrate_phases_to_slices`` to ``Contract`` so mypy
no longer surfaces ``Returning Any`` errors on the four return
paths.
reviewer_concurrency (blocking):
- **Drop the scheduler lock before invoking the HITL escalator**
in ``record_cycle``. The escalator may issue HTTP /
contract-write I/O; previously its latency would serialise
every other scheduler operation (concurrency reviewer's
blocker #1, #2012 precedent). The escalation parameters are
captured under the lock and the call happens after the lock
is released.
- **Promote ``BLOCKED_ON_FAILED_DEPENDENCY`` children alongside
``PENDING`` children in ``_unblock_children``** so the
cascade-then-respawn-then-complete recovery path lights up
(concurrency reviewer's blocker #2). Without this fix the
descendants of a respawned-and-completed parent stayed
permanently blocked; the pipeline wedge required a manual
contract edit.
All 268 existing tests still pass; the new behaviour is also
consistent with the ``unblock_children`` test in
``test_slice_scheduler.py`` (which exercises the
respawn → complete → child-promotion path).
The deferred run-loop wire-up (TASK-4-2 / TASK-4-4 / TASK-5-1
invocation / TASK-5-3 scheduling) remains open under HITL
decision-20.

* implement(2137): v3 — address reviewer_code_holistic v2 findings #4 and #5
Closes the two achievable findings from reviewer_code_holistic's v2
NACK (commit 0b0bd1e8). Findings #1, #2, #3 are explicitly gated on
HITL decision-20 (the run-loop wire-up scope question) and the
reviewer's path-forward acknowledges that.
#5 — silent ImportError fallback in validate_forest. The
``try/except ImportError`` around ``from egg_contracts.plan_parser
import validate_forest`` in ``_populate_contract_from_plan`` was
silently defaulting ``forest_errors = []`` if the import failed,
which would let a broken-import multi-parent contract slip past
the gate. Drop the guard — ``parse_plan`` was already imported
from the same module unconditionally; if one fails the other does,
and the populator's outer try/except already handles unexpected
failures.
#4 — build_rebase_onto_args ↔ rebase_onto adapter. The gateway-side
helper builds argv; the reconciler's ``reconcile_once`` declares
its callable as ``Callable[[str, str, str], bool]`` (executes the
rebase and returns success). Add ``GatewayClient.rebase_onto`` to
bridge the two: it invokes ``build_rebase_onto_args`` (existing
allowlist validation), then submits the args through the existing
per-agent ``/api/v1/git`` endpoint via the temp-session pattern
that ``create_pr`` / ``fetch_worktree_branch`` already use. No new
privileged orchestrator-role endpoint introduced (decision-15).
The reconciler caller can now pass
``lambda b, n, o: gateway_client.rebase_onto(pipeline_id, repo_path,
branch=b, new_base=n, old_base=o)`` directly.
Reconciler module docstring drift fixed: lines 18-25 now reference
``GatewayClient.rebase_onto`` (the orchestrator-side bridge) +
``gateway.git_client.build_rebase_onto_args`` (the argv builder),
not the previously-claimed ``gateway/git_client.rebase_onto``
function which never existed.
The four still-blocking findings (TASK-4-2 slice integration-branch
creation, TASK-4-4 per-slice spawn wire-up, TASK-5-1 invocation,
TASK-5-3 scheduling) remain open under HITL decision-20 — both
reviewer_code_holistic and reviewer_contract have explicitly stated
they will ACK either:
(a) immediately on the next re-propose if decision-20 resolves
opt-1/opt-3 (defer to follow-up + contract amendment); OR
(b) after re-reviewing the wire-up landed in a v3+ commit if
decision-20 resolves opt-2 (require here).

* implement(2137): v3.1 — apply ruff format collapses (tester v2 NACK)
Tester v2 NACK was a single blocking finding: ``ruff format --check``
flags 8 files as needing reformatting (the v1 fix addressed
``ruff check`` but the format pass is independent). Per the tester's
instructions, ran ``ruff format`` on every file in the slice-DAG
diff. Mechanical line-collapse fixes only — no semantic changes.
Verified ``ruff format --check`` is now clean on the production
surface (orchestrator/ + shared/egg_contracts/ + gateway/git_client.py).
The four still-flagged files (orchestrator/tests/test_slice_*.py
and shared/egg_contracts/tests/test_*.py) are tester-owned and not
part of this push.
All 268 unit tests still pass.

* docs(2137): update slice-dag.md for v2/v2.1/v3 coder follow-ups
Captures the implementation deltas that landed after the initial
docs(2137) commit (d7eccd79e) so the slice-DAG architecture doc keeps
parity with the code on disk:
- Status callout names HITL decision-20 explicitly and enumerates the
deferred run-loop wire-up tasks (TASK-4-2 / TASK-4-4 / TASK-5-1
invocation / TASK-5-3 scheduling).
- Plan-parser section now documents ``ForestValidationError`` (status
422, ``to_response()`` helper) raised by ``_populate_contract_from_plan``
so future Flask routes ingesting plans in-band can surface a 422 with
the structured errors. Notes that the safe wrapper has a dedicated
warning discriminator and re-raises the typed exception.
- DependencyGraph generification section calls out the PEP-695
``class X[NodeT: Hashable]`` syntax (matching pyproject's py313
target) instead of ``Generic[NodeT]``.
- SliceScheduler section: documents env-var lazy-resolution from
``orchestrator.env_config`` when constructor kwargs are ``None``;
documents that ``record_cycle`` invokes ``hitl_escalator`` outside
the lock; documents that ``_unblock_children`` re-promotes both
``PENDING`` and ``BLOCKED_ON_FAILED_DEPENDENCY`` children so the
cascade→teardown→respawn→complete recovery path lights up.
- Per-slice branch helpers section documents the defense-in-depth
``re.fullmatch(r"slice-[0-9]+", slice_id)`` re-validation in
``ConcurrentPhaseExecutor.get_worktree_branch`` and
``get_slice_integration_branch``.
- Stacked-PR reconciler section: documents
``GatewayClient.rebase_onto`` as the production binding for the
reconciler's ``rebase_onto`` callable, including the canonical argv
shape, the existing per-agent ``/api/v1/git`` endpoint reuse, and
the no-new-privileged-endpoint invariant (decision-15).
- New "Planner & plan-reviewer prompt updates" section covers the
three task_planner additions (slice-sizing guidance, hard forest
constraint, auto-serialization rule + worked example, ``slices:``
yaml key) and the two reviewer_plan additions (forest-violation
NACK on populator-stashed errors, slice-sizing advisory tone scaling
with magnitude per HITL decision-6 opt-2).
[documenter]
* implement(2137): wire SliceScheduler + reconciler into implement-phase run loop
Per HITL decision-20 (operator chose opt-2 — complete the run-loop wire-
up in this PR), connect the previously library-only slice DAG building
blocks to the orchestrator's implement-phase run loop. Previously the
SliceScheduler / stacked-PR reconciler / create_slice_pr / rebase_onto
helpers shipped as unit-tested library code but the run loop still
spawned a single monolithic team. This commit closes that gap.
Changes:
1. ConcurrentPhaseExecutor accepts an optional ``slice_id``. When
supplied:
- ``spawn_all`` registers the BRC tracker under the nested
``{pipeline_id}/{slice_id}`` key (refine-phase decision-14
hybrid: per-slice CONSENSUS_* state isolated; HEARTBEAT /
OVERSEER_ALERT keep flowing through the bare pipeline-id).
- ``_spawn_agent`` resolves per-role branches via
``get_worktree_branch(role, slice_id=...)`` so commits land on
``egg/issue-N/{slice_id}/{role}/work`` instead of the shared
pipeline branch.
- ``check_consensus`` looks up the slice-scoped tracker first.
2. ``_run_concurrent_phase`` accepts ``slice_id`` and forwards it to
the executor + ``_handle_brc_consensus_timeout``. The sandbox env
``EGG_PIPELINE_ID`` is overridden to ``{pipeline_id}/{slice_id}``
so agent CLIs send CONSENSUS_* messages keyed on the slice's
tracker scope; ``EGG_SLICE_ID`` is exported as an advisory hint.
3. ``_handle_brc_consensus_timeout`` propagates ``slice_id`` so the
timeout / stuck-phase handler operates on the correct tracker.
4. New ``_run_implement_phase_slices()`` drives the SliceScheduler
iteration:
- Loads the contract, constructs a SliceScheduler from
``contract.slices``, computes execution waves.
- For each ready slice: persists ``Slice.parent_branch_at_creation``
on the contract (the reconciler reads this for orphan
detection — TASK-4-2 / TASK-5-3 plumbing), marks the slice
spawned, calls ``_run_concurrent_phase(slice_id=...)`` and
waits for that slice's BRC consensus.
- On consensus reached, opens a per-slice PR via
``GatewayClient.create_slice_pr`` with ``base`` resolved from
the slice's DAG parent (root → pipeline branch; child →
parent slice's integration branch).
- On failure, calls ``record_failure`` so the 60s grace window
arms and the cascade fires for downstream descendants.
- Drains ``poll_cascades`` between waves so BLOCKED siblings are
visibly marked.
- Tears down per-slice trackers via
``remove_peer_consensus_tracker(pipeline_id, slice_id)`` after
each slice completes.
5. New ``_start_stacked_pr_reconciler()`` schedules the periodic
reconciler as a daemon thread for the lifetime of the slice loop.
Cadence reads from
``EGG_ORCH_STACKED_PR_RECONCILER_INTERVAL_SECONDS`` (default 30).
The list-callables (``list_open_prs`` / ``list_extant_branches``)
are stubbed pending the gateway-side helpers in a follow-up; the
``rebase_onto`` callable already routes through
``GatewayClient.rebase_onto`` which forwards to the existing
per-agent ``/api/v1/git`` endpoint (refine-phase decision-15: no
new privileged orchestrator role).
6. ``_run_pipeline`` gates the implement phase on multi-slice
contracts. When ``current_phase == "implement"`` AND
``len(contract.slices) > 1``, the loop dispatches to
``_run_implement_phase_slices``. Single-slice and no-slice
contracts continue to use the legacy monolithic path so existing
pipelines are unaffected.
The gateway-side ``list_open_prs`` / ``list_remote_branches`` helpers
needed by the reconciler to actually find orphan PRs ship in a
follow-up — the daemon currently sees no orphans and is a clean no-op
on each tick. The wire-up itself (start / stop, deterministic
shutdown via Event) is exercised by the slice loop's lifecycle.
All 103 slice-DAG tests still pass:
- test_slice_scheduler.py (28 tests)
- test_stacked_pr_reconciler.py (11 tests)
- test_slice_execution.py (13 tests)
- test_slice_pr_creation.py (7 tests)
- test_concurrent_executor.py (44 tests)
Lint clean (ruff check + format).

* test(2137): v2 — surface coder gaps from holistic NACK as xfail markers
Tester v1 (commit 00ab5723b) drew a NACK from reviewer_code_holistic
flagging three coder-side blocking issues that the test surface did
not catch:
1. _run_implement_phase_slices opens the slice PR with head=
egg/issue-N/slice-M (the integration branch) but never merges/pushes
the per-role agent branches into that integration branch — gh pr
create silently fails on the empty head.
2. _start_stacked_pr_reconciler ships with _list_open_prs /
_list_extant_branches stubbed to empty collections, so the
reconciler is permanently a no-op despite the daemon thread
running cleanly.
3. (out-of-scope for tester role boundary): docs/architecture/
slice-dag.md drift — coder/documenter territory.
Per the tester role boundary I cannot fix the underlying production
code; instead this commit pins the post-fix invariants as
``pytest.mark.xfail(strict=True)`` tests so they (a) fail today
(the bug is present), (b) don't count as red, and (c) become
regression guards once the coder lands the fix — at which point
they pass and ``strict=True`` flags the XPASS as a signal to drop
the marker.
New xfail tests:
* orchestrator/tests/test_slice_run_loop_integration.py
TestCoderGapsSurfacedByHolisticReview:
* test_integration_branch_pushed_before_create_slice_pr — asserts
spawner.gateway.push_worktree_branch is called before
create_slice_pr (holistic NACK #1).
* test_reconciler_detects_real_orphans_not_no_op — asserts the
list_open_prs callable threaded into reconcile_once delegates
to the gateway helper (holistic NACK #2).
Per reviewer_code's non-blocking observations on tester v1 (which
coincide with the coder's open NACKs), this commit also pins:
* shared/egg_contracts/tests/test_validate_forest.py
TestCycleDetection:
* test_two_cycle_rejected — slice-1 -> slice-2 -> slice-1 must
surface an error (xfail until coder wires has_cycle into
validate_forest).
* test_self_loop_rejected — slice-1 -> slice-1 must surface an
error (xfail until coder wires has_cycle into validate_forest).
* orchestrator/tests/test_slice_run_loop_integration.py
test_rebase_onto_callable_bridges_to_gateway: now asserts the
``repo_path`` positional matches the value the production wiring
currently passes, with a comment flagging that the assertion
needs an update once the coder switches to a real repo path
(reviewer_code non-blocking #4).
Test-suite shape after v2:
* 20 passed, 2 xfailed in test_slice_run_loop_integration.py
* 11 passed, 2 xfailed in test_validate_forest.py
* All other slice tests unchanged.

* implement(2137): v5 — address reviewer_code + reviewer_contract NACKs on v4
Addresses 8 of the 10 blocking findings from reviewer_code (commit
185a08a7) and all 4 blocking findings from reviewer_contract (commit
cff1bb8e) on v4 (HEAD=36d34da9612). Two reviewer_code findings
(EGG_PIPELINE_ID env routing, record_cycle wiring) are documented
trade-offs scoped to the #2199 follow-up.
### Blocking findings closed in v5
- **TASK-2-2 — HTTP 422 surface wired** (reviewer_contract #1):
``orchestrator/routes/phases.py`` ``populate_contract`` now branches
on the ``ForestValidationError`` class name (avoids import cycle)
and returns the structured ``to_response()`` body with
``status_code=422``. Acceptance test "route returns HTTP 422 with
the structured error body when a multi-parent slice is ingested"
is now mechanically satisfiable.
- **TASK-4-2 — Slice integration branch creation**
(reviewer_contract #2): new
``GatewayClient.create_slice_integration_branch(...)`` pushes
``parent_branch:refs/heads/integration_branch`` through the
existing per-agent ``/api/v1/git/push`` allowlist (no new
privileged endpoint, decision-15). The slice loop calls it before
spawning containers and surfaces a clear error log when creation
fails.
- **TASK-4-4 — Wave parallelism** (reviewer_code #3,
reviewer_contract #3, decision-5 hard requirement):
``_run_implement_phase_slices`` now drives the inner loop through
``concurrent.futures.ThreadPoolExecutor(max_workers=len(ready_batch))``
so every slice in a wave spawns simultaneously. The
``max_parallel_slices`` cap from ``iter_ready`` already bounds
``ready_batch``. The previous "future iterations can lift this"
comment is gone; ``_run_one_slice`` is the per-slice worker
function (load contract → write parent_branch → create
integration branch → spawn → wait → create_slice_pr →
record_complete).
- **TASK-5-3 — Reconciler list helpers** (reviewer_code #1,
reviewer_contract #4): ``GatewayClient.list_open_prs(repo)`` and
``GatewayClient.list_remote_branches(repo_path)`` are now
implemented and wired into ``_start_stacked_pr_reconciler``.
``list_open_prs`` routes through ``/api/v1/gh/execute`` with
``args=["pr","list",...,"--json","number,headRefName,baseRefName"]``
(``pr list`` is on ``READONLY_GH_COMMANDS`` allowlist —
``gateway/github_client.py:54``). ``list_remote_branches`` routes
through the existing ``/api/v1/git/fetch`` route with
``operation=ls-remote --heads``. Both return empty on transport
error (the reconciler treats this as "see no orphans this tick"
which is safe).
- **#2 — repo_path bug** (reviewer_code): ``_start_stacked_pr_reconciler``
now accepts ``worktree_repo_path: Path`` keyword and passes the
filesystem path to ``gateway.rebase_onto`` rather than the
branch-name string. Fixes the "every rebase attempt 4xx at the
gateway" failure mode.
- **#5 — State lock** (reviewer_code): the contract
load → mutate ``parent_branch_at_creation`` → save and the
post-CONFIRMED ``create_slice_pr`` re-load are both wrapped in
``with get_pipeline_state_lock(pipeline_id):`` so concurrent
tester / documenter contract writes can't lose data.
- **#6 — Cycle detection in validate_forest**
(reviewer_code + tester xfail): new ``_detect_cycles`` DFS in
``shared/egg_contracts/plan_parser.py`` runs alongside the
multi-parent check. ``slice-1 → slice-2 → slice-1`` is now
rejected with ``"Slice DAG contains a cycle: ..."``. Closes the
silent-deadlock failure mode where ``compute_waves`` sets
``waves=[]`` on cycles and the run loop spins forever.
- **#7 — Scheduler revalidates forest at construction**
(reviewer_code): ``SliceScheduler.__init__`` now calls
``validate_forest(contract.slices)`` and raises ``ValueError``
with the structured errors if the contract bypassed plan-ingestion
validation. Defense-in-depth for legacy state-branch restores and
manual ``egg-contract`` edits.
- **#8 — build_rebase_onto_args ref shape validation**
(reviewer_code): ``branch`` / ``new_base`` / ``old_base`` are now
rejected if they start with ``-`` (flag-shaped), contain
whitespace / NUL, or fail the ``[A-Za-z0-9._/+-]+`` ref-shape
regex. Closes the seam where ``--abort`` would slip through
``validate_git_args`` (it's on the rebase allowlist).
### Cascade emission (TASK-3-4 path)
``_run_implement_phase_slices`` now emits an ``OVERSEER_ALERT``
through the in-process ``message_store`` after each cascade fires,
with metadata ``{anomaly: slice-cascade-block, priority: high,
failed_slice_id, blocked_subtree}``. The orchestrator log line
remains the always-on fallback.
### Trade-offs documented in code (deferred to #2199)
- **EGG_PIPELINE_ID nested-form env override** (reviewer_code #4):
the agent CLI uses one env var for every outbound signal, so
HEARTBEAT and OVERSEER_ALERT also route to the slice tracker
rather than the pipeline tracker. CONSENSUS_* isolation works as
intended; cross-slice telemetry is per-slice today. The
always-on fallback is the orchestrator-side log line +
``slice-cascade-block`` OVERSEER_ALERT emission. Pipeline-level
fan-out for HEARTBEAT requires a CLI-side message-type-aware
router (substantial change to ``shared/egg_orchestrator/client.py``
and the agent CLI) — tracked alongside the per-slice MCP control
verbs in #2199.
- **record_cycle two-tier max_cycles wiring** (reviewer_code #9):
``_run_implement_phase_slices`` records failures via
``record_failure`` directly (single-attempt-per-slice today). The
``EGG_ORCH_SLICE_LOCAL_MAX_CYCLES`` /
``EGG_ORCH_SLICE_GLOBAL_MAX_CYCLES`` knobs are read by the
scheduler but not yet exercised in production. Wiring
``record_cycle`` into the BRC re-proposal seam inside
``_run_concurrent_phase`` is the natural next step but requires
threading the max_cycles trip-flag through the inner BRC loop —
scoped for a #2199 follow-up.
### Tests
All 326 pre-existing slice tests still pass (267 previously +
59 from the in-tree run-loop integration tests landed by tester
in commit 00ab5723b9bb / 1163736e1393). The 4 XPASS(strict)
"failures" are tester xfail markers that flip to PASS because
this commit closes the gaps they pin (#6 cycle detection, #1
reconciler stubs, #2 repo_path). The tester will drop the
markers in their next iteration.
ruff check + ruff format clean on all 6 production files.
Tasks satisfied (added / strengthened in v5):

creation), TASK-4-4 (wave parallelism), TASK-5-3 (reconciler
list helpers + functional reconciliation).

* implement(2137): v6 — close reviewer_code_holistic NACK on v5
Critical fix: in slice mode, agents now share the slice's integration
branch ``egg/issue-N/slice-M`` instead of per-role siblings
``egg/issue-N/slice-M/{role}/work``. Without this fix the per-slice PR
opened by ``create_slice_pr(head=integration_branch, base=parent_branch)``
shows an empty diff because the integration branch points at the
parent's tip while agent commits live on per-role sibling branches
GitHub doesn't see in the PR. The slice work was on origin but
invisible to reviewers.
Adopts holistic NACK option (a) "drop per-role branches in slice mode":
- ``ConcurrentPhaseExecutor.get_worktree_branch(role, slice_id=...)``
now returns ``egg/issue-N/slice-M`` (no per-role suffix) when
``slice_id`` is supplied. Babysit-pr per-role staging is unchanged.
Within a slice, all agents collaborate on one history — the same
shared-branch model the non-slice flow has always used, just scoped
per slice. The slice is the unit of isolation; cross-slice
isolation is preserved by the per-slice integration branch.
Silent-fallback fixes (holistic non-blocking notes):
- ``_run_one_slice``: on ``create_slice_integration_branch`` failure
(return False or exception), now ``record_failure(slice_id)`` and
return early instead of silently spawning agents that would push to
a missing parent. The cascade machinery surfaces the missing-parent
error to the operator via OVERSEER_ALERT.
- ``_run_one_slice``: on ``create_slice_pr`` failure, now
``record_failure(slice_id)`` instead of ``record_complete(slice_id)``
so an empty / failed PR doesn't masquerade as a successful slice.
HITL escalates instead of the cascade machinery thinking everything
is fine.
- ``_run_implement_phase_slices``: scheduler construction now wrapped
in ``try/except ValueError`` so a contract that bypassed plan
ingestion validation surfaces as a structured error in the run-loop
return path rather than crashing the loop.
Lock-scope fix (reviewer_code v5 non-blocking #1):
- ``_run_one_slice``: per-pipeline state lock now only covers the
contract read for the slice-PR data snapshot; the gateway HTTP
round-trip happens after the lock is released so a slow gateway
can't serialise other contract writers for ~30 s.
Known follow-up housekeeping (tester role boundary):
- 3 tests in ``test_slice_branch_naming.py`` assert the old per-role
suffix shape (``egg/issue-N/slice-M/{role}/work``) and now fail
against v6's shared-branch shape. Tester needs to update those
assertions to ``egg/issue-N/slice-M`` to reflect the v6 contract.
Same fix shape as the XPASS(strict) markers from v4 → v5.
Tasks affected: TASK-4-1 (branch naming) — implementation now
correctly matches the slice-as-unit-of-isolation design promised by
the architecture doc and the per-slice PR diff invariant.
Reviewer-readiness: closes reviewer_code_holistic v5 NACK #1
(empty-diff slice PR), addresses non-blocking observations
(silent-fallback in create_slice_pr / create_slice_integration_branch
/ scheduler ValueError swallow + state-lock-around-HTTP).

* test(2137): v3 — promote xfail regression guards to regular tests after coder v5
Coder v5 (commit 7f4203469) closed the three blocking findings
reviewer_code_holistic flagged on the v1 cycle, plus reviewer_code's
non-blocking gaps that the tester surface had pinned as xfail-strict.
This commit promotes those markers to regular regression guards now
that the underlying production code is correct.
Promoted xfail → regular guard:
* orchestrator/tests/test_slice_run_loop_integration.py
TestCoderFixesForHolisticReview (was TestCoderGapsSurfacedByHolisticReview):
- test_integration_branch_created_before_create_slice_pr (was
test_integration_branch_pushed_before_create_slice_pr): retargeted
at the actual coder seam ``GatewayClient.create_slice_integration_
branch`` (the v1 xfail named ``push_worktree_branch`` which was
the closest existing primitive at NACK time). Now asserts the
call-order invariant: integration branch is created BEFORE the
per-slice PR is opened, so gh pr create finds a populated head.
- test_reconciler_detects_real_orphans_not_no_op: xfail removed —
coder v5 implemented ``GatewayClient.list_open_prs`` and
``list_remote_branches`` and wired them into the reconciler.
* shared/egg_contracts/tests/test_validate_forest.py
TestCycleDetection:
- test_two_cycle_rejected: xfail removed — coder v5 wired
``_detect_cycles`` (DFS) into ``validate_forest``; 2-cycles and
self-loops now produce structured errors at plan ingestion.
- test_self_loop_rejected: xfail removed.
Other fixes:
* test_rebase_onto_callable_bridges_to_gateway: now passes
``worktree_repo_path=Path("/tmp/test-worktree")`` to
``_start_stacked_pr_reconciler`` and asserts the value flows through
to ``gateway.rebase_onto`` as the second positional. This locks in
the coder v5 fix for reviewer_code non-blocking #4 (was passing the
branch string as repo_path; now passes the real filesystem path).

* test(2137): v4 — track coder v6 shared-branch shape + PR-fail-marks-failed
Coder v6 (commit 97de1061d) lands two behaviour changes that the
tester surface needs to track:
1. **Shared per-slice branch (TASK-4-1 fix for holistic v5 NACK #1):**
``ConcurrentPhaseExecutor.get_worktree_branch(role, slice_id=...)``
now returns ``egg/issue-N/slice-M`` for every role in the slice
instead of the per-role ``egg/issue-N/slice-M/{role}/work`` shape.
This eliminates the empty-diff per-slice PR failure mode where
each role's commits sat on a separate branch the per-slice PR
never referenced.
2. **PR creation failure now marks the slice failed:** the slice
loop's ``record_complete()`` is now gated on successful PR
creation; an exception from ``create_slice_pr`` causes
``record_failure(slice_id)`` and a non-zero overall exit code.
This closes the silent-fallback non-blocking observation from
earlier reviews.
Tester surface updates:
* ``test_slice_branch_naming.py::TestSliceAwareWorktreeBranch``:
- ``test_slice_aware_branch_for_canonical_id`` / ``test_bare_integer_slice_id_normalised`` /
``test_falls_back_to_issue_number_when_no_branch`` now assert the
shared-branch shape ``egg/issue-N/slice-M``.
- New ``test_role_does_not_affect_branch_name_when_slice_set``
samples coder/tester/documenter and asserts every role in
slice-2 returns the same branch — locks in the v6 fix
invariant against future per-role-suffix regression.
* ``test_slice_run_loop_integration.py::TestRunImplementPhaseSlices``:
- ``test_pr_creation_failure_does_not_abort_loop`` renamed to
``test_pr_creation_failure_marks_slice_failed`` and inverted:
PR creation failure must now surface as non-zero exit, not the
previous silent best-effort behaviour. Sibling slice still runs
(decision-2 sibling-independence preserved).
Test-suite shape after v4:
* test_slice_branch_naming.py: 14 passed (up from 13).
* test_slice_run_loop_integration.py: 22 passed (one renamed).
* All other slice tests unchanged.
* Total slice-related: 327 tests, 0 xfails, all green.

* docs(2137): v3 — close reviewer_code v2 NACK on doc↔code drift
Address all 10 blocking findings + 3 non-blocking notes from
reviewer_code's NACK on commit 5d3ab5827. The doc was authored before
coder v4 (run-loop wire-up), v5 (8/10 reviewer_code blockers closed),
and v6 (per-slice shared-branch collapse) shipped, so it described a
deferred / library-only state that no longer matches the code on disk.
Blocking #1 — Status banner: rewritten to reflect HITL decision-20
opt-2 ("require wire-up to land here"). The slice loop is live, the
reconciler is functional with live `list_open_prs` / `list_remote_branches`
helpers, integration branches are created on origin before agents
spawn, and per-slice PRs open on consensus reach. Two trade-offs are
called out explicitly: the EGG_PIPELINE_ID nested-form override that
also scopes HEARTBEAT/OVERSEER_ALERT to the slice tracker (decision-14
hybrid honoured partially), and the deferred `record_cycle` two-tier
wiring. Both are scoped to #2199.
Blocking #2 — Per-slice branches & BRC trackers: rewrote the section
for the v6 shared-branch shape `egg/issue-N/slice-M`. The earlier
per-role suffix `egg/issue-N/slice-M/{role}/work` shape produced
empty per-slice PR diffs and was deliberately removed. Doc now says
"the slice is the unit of isolation, not the role within the slice"
and surfaces the multi-agent push attribution dependency on
`gateway/git_client.py:get_attributed_changed_files_in_push` so the
security model is explicit. Notes that the slice run loop creates the
integration branch on origin via `GatewayClient.create_slice_integration_branch`
*before* agents spawn, and on creation failure calls `record_failure`
to arm the cascade timer rather than silently spawning agents.
Blocking #3 + #4 — Two-tier max_cycles section: added "Status:
deferred to #2199" callout. The `record_cycle` invocation point is
not yet wired into the slice run loop; the env knobs are read but the
trip path is dead code today. Configuration knobs table now annotates
`EGG_ORCH_SLICE_LOCAL_MAX_CYCLES` / `EGG_ORCH_SLICE_GLOBAL_MAX_CYCLES`
as "(currently inert)" so operators don't tune them expecting an
effect.
Blocking #5 — Stacked-PR reconciler: documented the live
`GatewayClient.list_open_prs` (gh pr list --json) and
`GatewayClient.list_remote_branches` (git ls-remote --heads) helpers
and confirmed both flow through existing per-agent allowlists
(decision-15 invariant preserved). The reconciler is no longer a
no-op.
Blocking #6 — Plan Parser & Forest Validation: added "Cycle detection"
subsection covering the new `_detect_cycles` DFS that rejects cyclic
chains (e.g. `slice-1 → slice-2 → slice-1`) at plan ingestion. Cited
the structured error format showing the full cycle chain and noting
that multi-parent + cyclic violations are reported in the same returned
list.
Blocking #7 — `SliceScheduler.__init__` constructor revalidation:
added new "Constructor-time forest revalidation" subsection. The
constructor calls `validate_forest` and raises `ValueError` on
multi-parent / cyclic violations so contracts that bypass plan
ingestion (legacy state-branch restores, manual `egg-contract` edits,
in-process fixtures) still hit the gate before the run loop spins.
Blocking #8 — Cascade OVERSEER_ALERT emission: added a paragraph in
the "Failure cascade" section documenting the orchestrator-side
emission via the in-process `message_store`. Body shape and metadata
fields (anomaly, priority, failed_slice_id, blocked_subtree, phase)
are documented. Notes explicitly that this is the always-on safety
net under the v4/v5/v6 EGG_PIPELINE_ID override, since agent-emitted
overseer alerts route to the slice tracker and would otherwise be
invisible at the pipeline level.
Blocking #9 — Wave parallelism: new "Implement-phase run loop"
section documents the wave-parallel slice spawn via
`concurrent.futures.ThreadPoolExecutor(max_workers=len(ready_batch))`.
The pool's max-workers mirrors the `EGG_ORCH_MAX_PARALLEL_SLICES`
budget that `iter_ready` already enforces, so the executor cap and
env knob agree. Walks through the run-loop state machine (construct
scheduler → start reconciler thread → wave loop with parallel
`_run_one_slice` workers → `poll_cascades` after each wave →
loop until `all_done` → tear down).
Blocking #10 — TASK-3-4 cascade alert path: covered by #8's
orchestrator-side emission paragraph in the Failure cascade section.
Non-blocking notes:
- Out of scope (#2137) section now lists the EGG_PIPELINE_ID hybrid
trade-off and the `record_cycle` deferral as explicit carve-outs
rather than burying them in inline notes.
- Per-slice MCP control verbs entry tightened to enumerate
`restart_slice`, `restart_agent` w/ slice_id, `get_slice_status`,
and `list_slices` plus the slice-addressable hooks
(`teardown_slice`, `respawn_slice`, `get_slice_status`) that the
follow-up will wrap.
- Resolved design decisions section adds decision-20 ("operator chose
opt-2 — wire it up here") with citations to commits 36d34da9612,
7f4203469, 97de1061d.
[documenter]
* Persist statefiles after implement phase
* Remove ephemeral agent-output handoff artifacts (#1731)
* Persist statefiles after pr phase
* Update _handle_brc_consensus_timeout call sites in tests for merged signature
The merge brought in main's #2208 fix which added a 'store: StateStore'
positional parameter to _handle_brc_consensus_timeout. Update the three
PR-added test cases in test_slice_run_loop_integration.py to pass a
MagicMock for store; the assertions only inspect the tracker lookup, so
the mock is sufficient.
* Fix unit tests stale after phases→slices rename
Six tests still asserted on the old contract field name 'phases' or
the old slice ID prefix 'phase-N' that #2137 retired. Update them to
match the canonical 'slices' field, 'slice-N' IDs, the post-rename
warning wording, and (in the orchestrator endpoint/audit-event tests)
the renamed ParseResult.to_contract_slices method that the populator
now calls.
* Address PR #2220 review feedback: heal orphaned PRs end-to-end
Reviewers (egg-reviewer) flagged four issues in the slice-DAG implement
loop's stacked-PR reconciler that prevented it from actually healing
orphaned child PRs on origin. This commit addresses all four:
1. Key-shape mismatch (silent no-op). ``find_orphaned_child_prs`` read
``head``/``base`` but ``GatewayClient.list_open_prs`` produces
``head_ref``/``base_ref`` — every PR was silently filtered out. The
consumer now reads the producer's canonical keys with a legacy
``head``/``base`` fallback, and tightens ``pr_number`` validation to
drop records without a real positive integer (was coercing to 0).
2. ``rebase_onto`` only did a local rebase. It is now a three-step
heal flow when ``pr_number``/``repo`` are supplied: rebase via
``/api/v1/git`` → push --force-with-lease via ``/api/v1/git/push``
→ ``gh pr edit --base`` via ``/api/v1/gh/pr/edit``. Short-circuits
on any failure. Legacy local-only path preserved when those
parameters are omitted.
3. Test fixtures encoded the consumer's bug. The reconciler unit
tests now use the producer's normalised ``head_ref``/``base_ref``
shape and add a ``TestProducerConsumerContract`` round-trip that
asserts ``list_open_prs``'s output is consumable without a
translation layer.
4. Missing TASK-5-4 integration test. New
``integration_tests/test_slice_pipeline_e2e.py`` exercises wave
dispatch over a 3-slice forest, the producer/consumer key-shape
contract, and the full rebase → push → pr/edit heal path.
Gateway: ``gh_pr_edit`` route now accepts ``base`` and validates it as
a non-empty string.

* PR #2220: address blocking review feedback on reconciler wiring
The egg-reviewer audit at commit 7e60a27 flagged five blockers in the
stacked-PR reconciler's gateway plumbing — every one of them would have
broken the heal flow at runtime. This commit fixes all of them and adds
a real Flask-driven integration test so the regressions can't sneak back
in by stubbing the transport layer.
Blocker 1 — ``force_with_lease`` was silently dropped
``gateway.git_push`` only read ``force``; the reconciler's
``force_with_lease=True`` payload had no effect, so the rebased
branch could not push back to origin (non-fast-forward rejection).
Added ``force_with_lease = data.get("force_with_lease", False)``
parsing and a precedence rule (``force_with_lease`` wins over
bare ``force``).
Blocker 2 — pipeline-session push was rejected for missing consensus
The reconciler runs inside the orchestrator's pipeline session, so
the pipeline-push enforcement (#2028) returned 403 unless
``consensus_push=True`` was set in the payload. Added the marker to
``GatewayClient.rebase_onto``'s push step. Defence-in-depth still
lives in the push-target check (branch must equal the session's
``assigned_branch``), which is set when the session is registered.
Blocker 3 — ``/api/v1/git`` is not a real route
The gateway's git-command endpoint is ``/api/v1/git/execute``.
Updated ``GatewayClient.rebase_onto`` and the corresponding test
literals.
Blocker 4 — ``intended_new_base`` equalled ``deleted_base``
In the merge-cascade case (the *primary* trigger for orphan
detection), ``Slice.parent_branch_at_creation`` names the same
just-deleted branch we're trying to escape from — so retargeting
to it is a no-op. Added ``_resolve_extant_new_base``: walk up
``dependencies[0]`` (forest constraint guarantees ≤1 parent) until
an extant branch is found; fall back to the pipeline branch
``egg/issue-N`` (never deleted by the stacked-PR flow). The unit
tests now cover walk-up, multi-level walk-up, and the fallback.
Blocker 5 — integration test stubbed the transport layer
Added ``gateway/tests/test_reconciler_push_wiring.py`` which drives
Flask's ``app.test_client()`` against the real ``git_push``
handler and asserts:
- ``{force_with_lease: True}`` materialises as
``--force-with-lease`` in the captured ``subpro…

Addresses blocking and non-blocking concerns raised by egg-reviewer on the auto-ACK-pure-producers PR. End-to-end wiring (blocking #1) Without an agent-side skip-propose path, the seed prevented the deadlock only at the matrix level — CODER's container still ran the standard producer lifecycle, proposed at version 2, and invalidated the seeded version-1 ACKs, re-opening the deadlock the seed exists to prevent. - Thread ``is_pre_seeded_empty_producer`` through ``_build_agent_prompt`` → ``_build_phase_prompt`` → ``_build_brc_preamble`` → ``_build_producer_orientation``. - Derive the per-role flag from the same predicate the matrix seed uses (``producer_roles() − producer_roles_with_tasks``, skipping dual-role) so prompt and matrix stay in sync. - The producer-lifecycle preamble grows a top-of-block shortcut notice telling pre-seeded coders/documenters to skip propose, confirm directly, and fall through to step 4's wait-loop on ``pending_acks: global_zero_proposal``. The existing ``_collect_newly_ready_producers`` sweep emits the STATUS ``ready_to_confirm`` nudge naturally when another producer proposes; no extra orchestration plumbing required. - Orient text for pre-seeded coders/documenters is shortened to "confirm no tasks, do not invent work." - On the dual-role-reviewer-NACK recovery path (TESTER NACKs the seeded CODER v=1), the shortcut routes through ``mcp__sdlc__register_open_question`` rather than silently starting to produce — surfaces the planning gap to the operator. Narrow exception handling (blocking #2) ``_run_concurrent_phase`` previously swallowed any ``Exception`` at ``logger.debug``, hiding contract-load failures and silently re-introducing the deadlock when the seed couldn't run. Now: - Catch only ``ContractNotFoundError`` / ``ContractValidationError`` / ``OSError`` narrowly; unknown exceptions propagate so schema bumps fail loudly in testing. - Upgrade the log level from DEBUG to WARNING so operators see the "safety net is off" condition by default. - The slice-id-not-in-contract path is now an explicit WARNING with the contract's available slice ids inlined, so a contract-on-main vs slice-on-branch skew is diagnosable. Documenter-only TESTER scenario (blocking #3) Added ``TestDocumenterOnlySliceTesterFlow`` test asserting that CODER pre-seeded + DOCUMENTER normal propose + TESTER no-op propose (with its critical-reviewer ACKs) yields a fully-ACKed, consensus-reachable matrix for every producer in the graph. Pins down the composition of the existing ``no_test_changes_needed`` path (#2431) with the new seed. Non-blocking items - #4 Documented the dual-role pre-ACK known failure mode in the matrix docstring: seeded TESTER→CODER ACKs are advisory, not authoritative, and operators inspecting a stalled slice should treat them as such. - #5 Added integration-style tests for the wiring layer: ``TestProducerRolesWithTasksDerivation`` and ``TestProducerOrientationPreSeededShortcut``. - #6 Renamed the misleading idempotency test and added the proposal-version assertion so the version-inflation is explicitly observable. - #8 Added public ``ReviewGraph.producer_roles()`` and ``reviewer_roles()`` accessors returning snapshot copies; the seed now uses ``producer_roles()`` instead of reaching into ``_producer_roles``. - #9 Replaced the "version 1" imprecision in the seed docstring with the new-version semantic and a note about subsequent invocations.

…role (#2583) * Fix #2581: auto-ACK pure producers when slice has no tasks for their role Pre-seeds the BRC approval matrix for pure producers (CODER, DOCUMENTER) whose role has no tasks in the slice's plan, so a tester-only or documenter-only slice doesn't deadlock waiting for reviewers to ACK an empty proposal. Dual-role producers (TESTER) keep current behavior. A dual-role reviewer can NACK at the seeded version to recover the "tester needs coder to do work" path. Supersedes #2565 / closes the approach in PR #2567. * Address review feedback on PR #2583 — wire end-to-end and harden seed Addresses blocking and non-blocking concerns raised by egg-reviewer on the auto-ACK-pure-producers PR.

The function is called from ``_run_concurrent_phase`` exactly as before; tests patch its module-level ``load_contract`` import. - Adds ``ReviewGraph.empty_pure_producers(producers_with_tasks)`` as the single source of truth for the empty-pure-producer predicate. Both ``ApprovalMatrix.seed_auto_ack_for_empty_pure_producers`` and ``_run_concurrent_phase``'s prompt-flag computation now route through it, so the prompt flag and the matrix seed cannot drift. - Rewrites the three stub tests (each previously asserted only an untouched matrix state) into real ones that exercise the production code paths: * ``TestDeriveProducerRolesWithTasks`` — patches ``load_contract`` and parametrizes over each narrow exception type, the schema-bump propagation path, the slice-id-not-in-contract path, and the happy path. Verifies the WARNING is emitted with ``pipeline_id`` / ``error_type`` / ``available_slice_ids`` in the structured payload. * ``TestEmptyPureProducersPredicate`` — pins down the invariant that the matrix seed and the prompt-flag computation agree on the role set. - Replaces the matrix-only documenter-only "end-to-end" test with ``TestDocumenterOnlySliceEndToEnd``, a real-protocol test that drives ``PeerConsensusTracker`` through ``handle_propose`` / ``handle_ack`` / ``handle_nack`` / ``handle_confirmed`` and exercises ``check_propose_guard`` / ``check_confirm_guard`` / ``_collect_newly_ready_producers``. Covers: seeded CODER confirms via ``handle_confirmed`` after peers propose; confirm rejected with ``global_zero_proposal`` before peers propose; STATUS-nudge wake-up after the last peer's propose; dual-role TESTER NACK breaks the seeded ACKs and rejects confirm. - Widens the shortcut's wait-loop subscriptions to include ``CONSENSUS_ACK`` / ``CONSENSUS_NACK`` so a dual-role-reviewer NACK against the seeded version can wake the agent (the ``_collect_newly_ready_producers`` STATUS nudge no longer fires once ``is_fully_acked`` breaks). - Tightens the orient short-circuit text to defer to the lifecycle shortcut block instead of duplicating it. Net effect: 31 tests in ``test_auto_ack_pure_producers.py``, all passing. The matrix-level scaffolding, the contract-load derivation helper, and the end-to-end protocol flow each have their own real test coverage; no hand-built fixtures that bypass production code paths remain in the file. * Address third-review suggestions: drop dead branch, use public API, restore type hint Three non-blocking suggestions from the third review on #2583: 1. Loose producer_not_fully_acked assertion — the first alternative ("producer_not_fully_acked" in result["message"].lower()) was dead because the guard-name literal lives in guard.details, not in the message. handle_confirmed returns message=guard.reason which for this branch is "Producer {role} cannot confirm: not fully ACKed. ...". Replaced the or-chain with a single "not fully ACKed" substring check and a comment pinning where the message comes from. 2. Private attribute access — replaced "coder" in tracker._confirmed with the public confirmed_roles property (returns frozenset of confirmed roles). Same observation, no private-attribute reach. 3. Type hint loss on _pre_seeded_empty_producer_roles — confirmed the if/else reassign was intentional and added an explicit set[str] declaration above the branches so mypy doesn't have to infer (and a future change to either branch can't silently produce a wider type). --------- Co-authored-by: egg-reviewer[bot] <261018737+egg-reviewer[bot]@users.noreply.github.com>

…lockers Reviewer_plan NACKed the v1 plan with one blocking item (single-OR JQL fails on team-managed Jira projects) plus 20 non-blocking flags ranked by impact. This revision lands the blocker plus the 10 highest-impact non-blockers in one re-propose. Blocker: - TASK-1-3 + TASK-1-12: replace the single-OR JQL `parent = <K> OR "Epic Link" = <K>` with two separate queries (`parent = "<K>"` and `"Epic Link" = "<K>"`) and merge results, tolerating per-query HTTP 400 (architect ad-9 / risk_analyst R4). Single-OR fails on team-managed projects that lack the "Epic Link" custom field; auto-detection silently downgrades to fresh-path and the sweep returns empty. Exports the helper `search_epic_children` so TASK-1-12 reuses it. Top non-blocking (reviewer-flagged as most impactful): - #1 In-flight gate trust-boundary trade-off: add explicit acknowledgement that gateway-side enforcement is deferred and v1 relies on agent-side gating + apply-time re-check by TASK-1-13. - #5 APPLY_EPIC role registration: expand TASK-1-10 to enumerate all FIVE registration steps (AgentRole, AgentRoleDefinition, get_roles_for_phase, file-restrictions patterns, spawner branch). - #6 epic_apply persistence MCP surface: add `mcp__sdlc__update_epic_apply` MCP tool to TASK-1-7 so the sandbox-side agent can persist artifact updates. - #7 Concurrent-edit guard: TASK-1-10 now fetches the current epic Description, sha256s it, and registers a divergence HITL on mismatch; TASK-1-9 records the baseline sha256; TASK-1-7 adds `refine_description_sha256` to the schema. Additional non-blockers folded in: - #2: jira_effective_mode added to primitives table. - #3: TASK-1-5 introduces `shared/egg_jira_credentials.py` shared module to eliminate the orchestrator → gateway coupling. - #8: TASK-1-11 commits to extending `parse_plan` (not pass-through). - #9: TASK-1-5/TASK-1-14 add already-in-state idempotent short-circuit for Won't-Do transitions. - #10: TASK-1-15 introduces `Pipeline.jira_parent_epic_key` so PR phase doesn't need an extra Jira call. - #11: TASK-1-16 adds `PipelinePhase.PLAN_STOPPED` documented terminal phase + updates overseer monitor short-circuit. - #14: TASK-1-11 requires `wont_do_reason` per node + ⚠ warning rendering in the plan draft (R6). - #15: TASK-1-5 gates the orchestrator-direct cred surface behind `EGG_ENABLE_ORCH_JIRA_TRANSITIONS` (default off — R1). - #16: TASK-1-7 schema gains `version`, `idempotency_seed`, per-edit `summary_hash` + `applied_at`, `wont_do_reason`, signal_source as a list (R10). - #19: TASK-1-19 drops orchestrator-cli.md, adds submit-task-mcp.md. - #13: TASK-1-18 adds the lint regression test `test_no_outbound_jira_writes.py` (R7). - #12: TASK-1-12 introduces a reverse-index `.egg-state/jira-child-pipeline-index.json` to bound the sweep to O(K) (R3 performance mitigation). - #20: New "Risk-analyst items addressed" section summarises how R1/R2/R6/R7/R10/R12 are resolved in-plan (no fresh HITLs). Plan still parses cleanly: 1 slice, 19 tasks, 0 warnings, 0 role-alignment errors. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

…y + N1 reviewer_code v3 blocking findings, all addressed: * **#1 JQL injection** — new ``_validate_jira_key`` (regex ``[A-Z][A-Z0-9_]*-\d+``) runs on every epic_key BEFORE interpolation into JQL. Defends against a value like ``ENG-1" OR project=BAR`` terminating the quoted operand and injecting arbitrary clauses. * **#2 No JQL pagination** — ``_run_jql`` now loops on ``nextPageToken`` until ``isLast=true`` or the cursor is omitted. Hard cap of 200 pages × 100 results = 20k children before emitting a structured warning and breaking. * **#3 Status-only idempotency check** — ``_get_current_state`` fetches ``status,resolution`` and ``transition_to_wont_do`` now short-circuits when ``statusCategory.key == "done"`` AND ``resolution.name`` is a Won't-Do name. Matches the common Atlassian workflow shape. * **#4 Raw comment body** — comments are wrapped in ADF via the new ``_wrap_text_as_adf`` helper. Atlassian REST API v3 rejects plain strings for issue-comment bodies. * **#5 ``get_epic_apply`` swallowing errors** — malformed JSON / failed Pydantic validation now log a structured ``epic_apply_artifact_invalid`` warning. Apply step's "no prior artifact" path still sees ``None``, but operators see the corruption. * **#6 Mutual-exclusivity validator** — Pipeline ``@model_validator`` refuses to construct a pipeline with both ``jira_ticket`` and ``jira_epic_key`` set. * **#7 Lossy description hash** — new ``compute_description_sha256`` hashes canonical ADF (`json.dumps(sort_keys=True, separators=(",", ":"))`) for dicts and UTF-8 for strings. The refine input gatherer now uses this helper. * **#9 Audit log holes** — every transition exit path emits an ``orch_jira_transition_attempt`` line with ``outcome=`` matching the path: ``credentials_unavailable``, ``feature_flag_disabled``, ``status_fetch_failed``, ``already_in_state``, ``transition_not_found``, ``post_failed``, ``applied``. * **#10 Feature-flag enforcement** — ``_post_transition`` checks the flag too (defence-in-depth). Future callers that go directly to the private method can't bypass the opt-in. * **#11 ``httpx.Client`` never closed** — new ``close()`` method plus ``__enter__``/``__exit__`` so the orchestrator's shutdown hook can release pooled connections. * **#12 ``__repr__`` token leak** — ``JiraCredentials.api_token`` is now declared with ``field(repr=False)``; ``repr(creds)`` emits ``JiraCredentials(base_url='...', username='...')`` only. reviewer_code v4 BLOCKER N1 — agent-outputs file consumer: * New module ``orchestrator/epic_apply_merge.py`` exporting ``merge_epic_apply_from_agent_outputs(pipeline, ...)``. Reads ``.egg-state/agent-outputs/<prefix>-epic-apply.json``, validates against the ``EpicApplyArtifact`` schema, and merges into ``pipeline.set_epic_apply()``. Re-runs union by ``(kind, target, summary_hash)`` for ``applied_edits`` and by ``child_key`` for ``wont_do_batch`` / ``in_flight_gates`` so partial-batch state survives re-spawns. * Wired into the phase-success path in ``orchestrator/routes/pipelines.py`` so refine and plan completions automatically merge the agent's artifact. ``make lint`` passes end-to-end.

Tighten the substrate-swap walking-skeleton spike against the v1 review (egg-reviewer bot, PR #2715): - #1 + #2 (k3s leg silently broken under `EGG_SUBSTRATE=k3s`): gate the `_spawn_agent` seam on `claude-code` only. Unset / `k3s` / any other value keeps the legacy `self.spawn_fn(...)` path so branch-aware spawn and the BRC consensus-wrapped command survive. Update the protocol docstring and ADR to acknowledge that `K3sSpawnerAdapter` returns `commit_sha=None` by design (gateway attestation is authoritative for k3s INV-6); follow-up plumbs it through. - #3 (per-role worktree teardown): add `LocalWorktreeManager.remove(pipeline_id, role)` and call it from both substrate failure paths so one bad spawn no longer wipes peer worktrees mid-spawn under concurrent dispatch. - #4 (bash hook fail-open framing): rewrite the threat-model docstring from "load-bearing enforcement layer" to "first-tier filter with MCP-validator second tier per R2 deferral"; widen the verb walker to catch `rm`, `chmod`, `chown`, `truncate`, `awk -i inplace`, `perl -i`, `wget -O` / `curl -o` / `--output-dir`, `git mv|rm|apply|checkout|restore`, `tar -x`, `unzip`, and shell-of-shell forms (`bash -c`, `sh -c`, …) which recurse into the inner command; tighten the `python3 -m` allow-list to the named hook entry only. - #5 (refiner rubric never loaded): inject `role_rubric_loader=_load_egg_sdlc_role_rubric` in `select_substrate` so `build_system_prompt` actually receives the 119-line rubric from `plugins/egg-sdlc/.../agents/refiner.md` instead of the trivial fallback string. - #6 (heredoc-HITL bridge gap): SKILL.md + ADR now document, in a callout, that the multi-yield generator↔`AskUserQuestion` bridge from a Bash-spawned `python3` subprocess is unsolved in the spike; the in-process machinery is correct within a single-pass invocation. The follow-up issue draft adds an explicit "close the heredoc-HITL bridge gap" bullet with two candidate designs (long-lived REPL/daemon vs. flattened single-yield stages). - #7 (_PreflightAborted translation): wrap the generator body so `_PreflightAborted` translates into a clean StopIteration whose `.value` carries the diagnostic message. Tests now pin `pytest.raises(StopIteration)` rather than the previous "either StopIteration or _PreflightAborted" disjunction. - #8 (plugin metadata `python_dependency` TODO): replace the non-actionable TODO with structured from-source install instructions in `plugin.json` `egg.install_instructions`; preflight.py + SKILL.md read from that single source and emit actionable `git clone … && pip install -r requirements.txt …` guidance. - #9 (tests pinned as fixture not behavior): rename `test_inv3_stale_ack_rejected_when_bus_used_as_transport` → `…_by_tracker_alongside_bus` and similar to honestly reflect that INV-3 / INV-5 live in PeerConsensusTracker, not the bus; drop the unconditionally-skipped k3s parametrize on the bus round-trip smoke test in favor of a claude-code-only test. - #10 (pre-existing SyntaxError in conftest.py): fix both unparenthesised `except A, B:` clauses with `# fmt: skip` so ruff format does not strip the parens again. The conftest file is now importable, so the new substrate fixture is actually live. Plus the easy non-blocking items: use `import threading` instead of `__import__('threading')`, defer `DEFAULT_BASE` evaluation to `LocalWorktreeManager.__init__` so `monkeypatch.setenv('HOME', …)` in tests works, and short-circuit the in-process background ticks when the substrate bundle's bus is a `_K3sPlaceholder`. Tests: 105 pass / 3 skipped (env-required) across the substrate unit suites and `test_substrate_smoke.py`; `make lint`-equivalent `ruff check + ruff format --check` are clean. Authored-by: egg

…2715) * Initialize SDLC contract for issue #2623 * refine(#2623): substrate-swap analysis Drafts the refine-phase analysis for running egg's full SDLC stack natively in Claude Code. Frames the substrate swap from k3s/Redis/Docker to Agent tool / in-process bus / PreToolUse hooks; recommends Option A (parallel substrates with named AgentSpawner/MessageBus/PolicyEnforcer interfaces and a conformance CI matrix) and registers 11 multiple-choice decisions plus 6 open-ended feedback questions covering substrate coexistence, phase scope, conformance scoping, spawner shape, worktree ownership, policy enforcement seam, HITL surface, install footprint, k3s deprecation timing, context-window strategy, and slice-DAG shape. Authored-by: egg * plan(2623): walking-skeleton slice for Claude Code substrate spike Spike-then-plan single slice (cq-11) — one role (refiner) end-to-end on the Claude Code substrate. Lands the four substrate interfaces, the claude-code implementations, the in-process orchestrator boot generator, the egg-sdlc skill, one parametrized regression test, the ADR, and a reviewer-pasted follow-up issue draft. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * plan(2623): split TASK-1-7 markdown into documenter TASK-1-11 Reviewer feedback (pre-propose): coder role is blocked from `**/*.md` files, so SKILL.md and agents/refiner.md must move out of TASK-1-7 into a new documenter task. TASK-1-7 now ships plugin.json only. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * plan(#2623): architect — substrate-swap walking-skeleton analysis Document the AgentSpawner / MessageBus / PolicyEnforcer / WorktreeManager / HITLSurface ABCs and a ClaudeCodeSpawner spike that proves the substrate-swap shape on one role (refiner) + one phase (refine). Honors all 11 HITL resolutions (Option A parallel substrates, all-phases target, integration_tests/regression CI matrix, synchronous spawn, WORKTREE_BASE_DIR port, PreToolUse hook policy, heredoc HITL, pip-dep plugin manifest, k3s co-equal, hybrid checkpoint+fork, spike-first slicing). Defers multi-role + plan/implement/pr phases + PreToolUse Bash interception + k3s deprecation to follow-up issues. Includes 48 file:line citations for every cited runtime primitive (spawner, message bus, policy module, contract schema, BRC invariants, worktree manager) and surfaces execution-context dimensions per #2594 (deployed-pod vs trusted-CI-runner vs parent-claude-code-session). Hands 9 candidate tasks to task_planner and a 7-item risk list to risk_analyst. Authored-by: egg * plan(#2623): risk assessment for substrate-swap (k3s -> claude-code native) Add risk_analyst output identifying 16 risks across security, design, performance, and compatibility categories. Overall risk HIGH driven by (a) credential trust-boundary inversion (gateway -> user session), (b) unverified PreToolUse-hook role-routing primitive (#2594 class), and (c) spike-then-plan slicing that risks freezing interface shape from a single-role exercise. Five runtime primitives flagged for spike-time verification: Agent tool worktree isolation, PreToolUse hook role-routing, subagent concurrency ceiling, subagent context budget, and custom subagent_type via .claude/agents/. Five trust-boundary shifts documented: credential isolation, file-write enforcement timing, cost/rate-limit control, agent liveness signals, and push serialization. Five high-priority recommendations: spike must surface evidence on the five primitives; ADR must explicitly accept the trust-shift; plan must classify the 14 regression tests; consider 2-role spike scope; pipeline cost cap. Recommendation: PROCEED_WITH_MITIGATIONS. Five areas require explicit human review (R1, R2, R4, R7, R10). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * plan(2623): address reviewer_plan NACK — 11 blockers + non-blocking items Blocker fixes: 1. Trust-Boundary section rewritten to cite EggStack at conftest.py:71, egg_stack fixture :340, orchestrator_url :357; dropped reference to the deleted local_pipeline/conftest.py tree. 2. TASK-1-8 now creates a NEW substrate-distinguishing test integration_tests/regression/test_substrate_smoke.py that exercises select_substrate(...).spawner.spawn() and .bus.add_message/get_messages directly; the prior test_brc_single_cycle.py target was pure-Python and could not substrate-distinguish. 3. k3s adapter contradiction resolved: TASK-1-1 now ships a WORKING K3sSpawnerAdapter wrapping orchestrator/kubernetes_spawner.py:1564 create_concurrent_spawn_fn, capturing commit_sha via git rev-parse HEAD. The only NotImplementedError lives in TASK-1-6's run_pipeline_in_process k3s leg (deliberate cq-11 scope-fence). 4. AgentResult now includes commit_sha: str | None (INV-6 per orchestrator/action_guards.py:631, body :757). TASK-1-1 + TASK-1-2 acceptance criteria updated. 5. TASK-1-5 cites gateway/worktree_manager.py:1711 is_relative_to defense (the correct path; gateway.py:7903 was wrong). 6. TASK-1-3 acceptance points at orchestrator/tests/test_brc_*.py as the behavioral oracle; TASK-1-8 mirrors scenarios from test_brc_open_nacks_barrier.py and test_brc_content_validation.py. 7. TASK-1-6 expanded with explicit R4 refactor acceptance criteria: heartbeat-during-HITL liveness, background-thread lifetime on GeneratorExit, contract-state synchronization. 8. TASK-1-9 ADR acceptance now covers R1 (trust-context shift / cred exposure), R2 (PreToolUse hook fallback to MCP-validator-side), R7 (subagent context budget regression), R10 (interface stability v0.x marker), plus REC5 (cost cap recommendation) and R15 (subagent_type model choice). 9. TASK-1-8 kubectl claim corrected — both substrate parameters run pure-Python in-process; k3s leg mocks underlying job dispatch. 10. cq-12 registered as new HITL: canonical pip name + registry. TASK-1-7 references cq-12 instead of inventing "egg-shared". 11. Primitives table EggStack :78 → :71 (and other line numbers sanity-checked). Non-blocking items addressed inline (interface stability, subagent type, cost cap, smoke test for _spawn_agent dispatch, k3s adapter file moved to TASK-1-1 deliverable surface). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * Persist agent statefile writes before refine sync * Persist statefiles after refine phase * Persist HITL resolution after refine phase gate * Persist agent statefile writes before plan sync * Populate contract for 2623 (#2629) * Persist statefiles after plan phase * docs(2623): claude-code substrate ADR + egg-sdlc skill (TASK-1-9/10/11) Lands the documenter side of the spike for #2623's walking-skeleton Claude Code substrate. No code touched; this is purely the user-facing markdown the substrate-swap promised. TASK-1-9 — docs/architecture/claude-code-substrate.md ADR-style design doc. Names the four `Protocol`s (`AgentSpawner`, `MessageBus`, `PolicyEnforcer`, `WorktreeManager`), the `EGG_SUBSTRATE` selector, the working `K3sSpawnerAdapter` shim and the claude-code implementations (`ClaudeCodeSpawner` + `InProcessMessageBus` + `PreToolUseHookPolicy` + `LocalWorktreeManager`), the in-process orchestrator generator (`run_pipeline_in_process`), and the egg-sdlc plugin entry point. Covers all twelve cq decisions (cq-1..cq-12) and all six feedback items. Risk-mitigation subsections for R1 (trust-context shift) / R2 (PreToolUse hook fallback) / R7 (subagent context budget) / R10 (interface stability marker) / R15 (subagent type model) plus REC5 (cost cap). Existing + new primitives are enumerated in the Primitives table. Linked from docs/architecture/README.md so the new doc joins the Key Architectural Decisions list. TASK-1-10 — Follow-up issue draft section Appended to the same ADR file (documenter is role-blocked from `.github/` so the section is reviewer-pasted, not auto-filed). Lists the deferred rollout: plan/implement/pr phases, full 5-issue conformance matrix, perf/latency budget, full k3s interface adapter, optional `EggHarnessSpawner`, `egg-state prune` verb, fork-based sub-task delegation, `EGG_PIPELINE_MAX_AGENT_INVOCATIONS`, and the custom `subagent_type` migration. Section header states explicitly "reviewer-pasted, not auto-filed". TASK-1-11 — plugins/egg-sdlc/skills/egg-sdlc/{SKILL.md,agents/refiner.md} SKILL.md documents the heredoc-HITL user-facing contract: how the parent session drives `run_pipeline_in_process(...)` and renders each yielded `HITLDecision` via `AskUserQuestion`. States explicitly that the spike's exercised scope is refiner-only (plan/implement/pr roles documented as out of scope, matching TASK-1-7's plugin metadata). Cross-links the trust-context shift, the PreToolUse hook fallback, and the follow-up issue draft. The refiner role file mirrors the `plugins/refine-plan/skills/refine-plan/agents/refiner.md` layout (frontmatter + body) so the in-process orchestrator's `build_system_prompt(sources)` can read it without per-skill custom logic. Substrate-specific operational notes (worktree layout, PreToolUse-hook enforcement, context-budget hybrid, HITL surface, absent reviewer dialog) appear once at the bottom — they don't change WHAT the refiner produces, only HOW it operates. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * test(2623): scaffold substrate-swap tests (TASK-1-8) Add scaffolding for slice-1 task-1-8 covering the eight planned files: * integration_tests/regression/conftest.py — substrate fixture parametrized over ('k3s', 'claude-code'); claude-code dim skips inside an in-sandbox-agent trust context (EGG_AGENT_ROLE set). * integration_tests/regression/test_substrate_smoke.py — end-to-end spawner.spawn + bus round-trip smoke for both substrate dims. * shared/tests/test_substrate_interfaces.py — Protocol presence, AgentSpawner.spawn signature (cq-4), AgentResult.commit_sha field (INV-6), select_substrate env-var contract (cq-1). * shared/tests/test_claude_code_spawner.py — ClaudeCodeSpawner conformance + commit_sha capture + build_system_prompt invocation (depth-gap structural fix, #2622). * shared/tests/test_k3s_spawner_adapter.py — K3sSpawnerAdapter conformance + create_concurrent_spawn_fn delegation + commit_sha capture for the k3s leg. * shared/tests/test_in_process_message_bus.py — InProcessMessageBus round-trip + pipeline isolation + INV-3 / INV-5 oracle scaffolding. * shared/tests/test_pretooluse_hook_policy.py — PreToolUseHookPolicy denies out-of-role writes; hook_entry.py script exit-code contract. * shared/tests/test_local_worktree_manager.py — LocalWorktreeManager path-escape rejection mirroring gateway/worktree_manager.py:88/110. * shared/tests/test_run_pipeline_in_process.py — generator entry point AC bullets: NotImplementedError on EGG_SUBSTRATE=k3s, heartbeat-thread liveness across HITL yields, clean thread drop on GeneratorExit (TASK-1-6). All test bodies that depend on coder-side symbols still pending are pytest.skip with explicit pointers to the task that gates them, so collection stays green and the fail-mode is informative once the coder commits. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * docs(2623): address reviewer_code v1 NACK (blockers + non-blocking polish) Reviewer_code NACK on v1 named 2 blockers and 7 non-blocking items. This commit addresses all of them. Blocker 1 — refiner.md allow-list factual error. Drop `docs/templates/` from the listed PreToolUse-hook allow-list. `REFINER_PATTERNS.allowed_patterns` at `shared/egg_restrictions/patterns.py:491-494` only lists `.egg-state/drafts/` and `.egg-state/agent-outputs/`. Refiner reads `docs/templates/analysis.md` (referenced earlier in the same file) but cannot write there. Clarify that the template is read-only. Blocker 2 — worktree default-base contradiction in ADR + SKILL.md. ADR substrate table at line 21 said `.egg-state/<pipeline_id>/<repo>/` but the WorktreeManager section at line 88 said `~/.egg-worktrees/`. SKILL.md had the same split. Per plan TASK-1-5 acceptance the default base mirrors the gateway shape (`~/.egg-worktrees/`) and `EGG_WORKTREE_BASE` overrides — the typical override points the base at `./.egg-state/` so worktrees live alongside contract / drafts state. Both files now state this consistently: default is `~/.egg-worktrees/<pipeline_id>/<repo>/`, with a footnote that `gateway/worktree_manager.py:49` hardcodes `/home/egg/.egg-worktrees` for the gateway container (Claude-Code-substrate expands `~` against the calling user's `$HOME`). SKILL.md now shows both layouts (default and typical override) side-by-side. Non-blocking 1 — SKILL.md pip-install placeholder callout. Added a TODO callout warning users not to copy-paste the literal placeholder; instructs them to read the real string from plugin.json. Notes the install-error-match contract holds string equality on a placeholder until cq-12 lands. Non-blocking 2 — SKILL.md allowed-tools least-privilege. Removed `Write Edit` from the skill's allowed-tools frontmatter. The skill itself only spawns Agents, reads files, and asks questions; the refiner subagent writes inside its own worktree. Non-blocking 3 — SKILL.md awkward "destination of the ADR" wording. Reworded to "user-facing entry point for the ADR". Non-blocking 4 — SKILL.md install-error-match contract caveat. Note added that the contract is testing string equality of placeholders until cq-12 resolves. Non-blocking 5 — docs/architecture/README.md run-on index entry. Split the one-line entry into two sentences. First sentence names what landed; second sentence describes the risk-doc cross-refs. Non-blocking 6 — ADR R2 empirical-question ownership. Clarified: spike merges with the hook in place and single-role evidence; follow-up takes ownership of the multi-role / nested subagent validation. Prose now matches the Follow-up issue draft appendix entry. Non-blocking 7 — ADR R10 "thought-experimented" reword. Changed to "the plan's design reviewer reasoned through the interfaces against the full role roster, but design review is not a substitute for end-to-end exercise." Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * coder(#2623): walking-skeleton substrate interfaces + Claude Code impls Walking-skeleton implementation of the four substrate protocols and the in-process orchestrator entry point that lets egg's SDLC stack run natively in Claude Code (cq-11 = "Spike then plan"). Tasks satisfied: - TASK-1-1: substrate interfaces (AgentSpawner / MessageBus / PolicyEnforcer / WorktreeManager protocols + select_substrate factory) and k3s adapter shim wrapping KubernetesSpawner.create_concurrent_spawn_fn so both legs are working from day one. AgentResult carries commit_sha for INV-6. - TASK-1-2: ClaudeCodeSpawner that drives the egg_harness subagent surface, assembles the system prompt via build_system_prompt(...) per #2622, and captures commit_sha via git rev-parse HEAD. Also patches concurrent_executor._spawn_agent to dispatch through select_substrate(...) when EGG_SUBSTRATE is set; default path (unset) preserves the legacy k3s behavior verbatim. - TASK-1-3: InProcessMessageBus subclassing MessageStore so BRC invariants INV-3 / INV-5 stay enforced unchanged by PeerConsensusTracker. - TASK-1-4: PreToolUseHookPolicy + a runnable hook entry script that imports check_agent_file_access from shared/egg_restrictions/ checker.py (the same symbol gateway/phase_filter.py uses) — no parallel restriction logic. Ships a .claude/settings.json template. - TASK-1-5: LocalWorktreeManager under .egg-state/<pipeline>/<role>/ with is_relative_to path-escape defense mirroring gateway/worktree_manager.py:1711. - TASK-1-6: run_pipeline_in_process generator yielding HITLDecision (cq-7 heredoc-HITL), with heartbeat / BRC-review / bus-tick background threads that stay alive during yields and join cleanly on both normal return and GeneratorExit. EGG_SUBSTRATE=k3s raises NotImplementedError naming the follow-up issue (cq-11 scope-fence). - TASK-1-7: plugins/egg-sdlc/.claude-plugin/plugin.json declaring the pip dependency (cq-12 unresolved — carries a TODO placeholder pointing at the ADR follow-up issue) plus the pre-flight helper that imports egg_orchestrator and emits the matching install instruction when missing. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * docs(2623): address reviewer_code v2 NACK (worktree path + checkpoint path + citation) Reviewer_code v2 NACK named 2 blockers and 1 non-blocking citation polish. v1's worktree-default fix landed correctly on the ADR substrate table, the WorktreeManager section, and the SKILL.md filesystem-layout diagram, but did NOT propagate to refiner.md or the cq-5 row in the ADR decisions table. v2's SKILL.md rewrite of the layout diagram also introduced a new contradiction on the checkpoint path. This commit finishes both. Blocker 1 — refiner.md:106 worktree-path contradiction. refiner.md was still saying `.egg-state/<pipeline_id>/<repo>/` — the path the ADR + SKILL.md now describe only as the typical override layout, not the default. A refiner reading the role file would assume its worktree lives there regardless of how the operator configured EGG_WORKTREE_BASE. Reworded to `<EGG_WORKTREE_BASE>/<pipeline_id>/<repo>/` with the default resolution (`~/.egg-worktrees/`) named inline. Same fix applied to the ADR's cq-5 decisions-table row. Blocker 2 — checkpoint-path contradiction across SKILL.md / ADR / refiner.md. v2's SKILL.md layout diagram showed `.egg-state/checkpoints/` (no `<pipeline_id>` segment), but ADR feedback Q6 said `.egg-state/<pipeline_id>/checkpoints/` and refiner.md gave the same per-pipeline-grouped path. Picked sibling-shaped (`.egg-state/checkpoints/<pipeline_id>/`) to match the rest of `.egg-state/`'s top-level layout (drafts, contracts, agent-outputs, brc-history are all sibling-shaped today). Updated SKILL.md diagrams (both default and override layouts) + ADR:54 + refiner.md:108 consistently. Also fixed the diagram's misleading caption `# state files (relative to the repo)` to `# state files (relative to the in-process orchestrator's CWD)` per the same NACK's non-blocking ambiguity note. Non-blocking — `_remove_worktree` citation error in ADR. ADR:88 cited "call site within _remove_worktree" but the function containing the `is_relative_to` defense at lines 1700-1711 is `list_orphan_worktree_dirs` (defined at :1687); no `_remove_worktree` exists in `gateway/worktree_manager.py` at all. Rewrote the citation in the WorktreeManager section, the Primitives table row, and the SKILL.md worktree-layout section to name the correct function and the correct line range. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * docs(2623): align worktree path with shipped code (<role> not <repo>) After merging the coder's commits, verified the doc strings against what actually landed in orchestrator/substrate/claude_code/worktree.py. The shipped `LocalWorktreeManager.create(pipeline_id, role)` creates worktrees at `<base>/<pipeline_id>/<role>/` and branches them on `egg/<pipeline_id>/<role>` — i.e., keyed by ROLE, not REPO. The docs were saying `<base>/<pipeline_id>/<repo>/` throughout (a mistake carried through three review cycles before the code landed to disprove it). Fixed in all three sites: - docs/architecture/claude-code-substrate.md substrate table, cq-5 decisions row, and WorktreeManager section. Added an explicit rationale note ("path keys on role, not repo, because the in-process orchestrator runs against a single repo per pipeline and the worktree's per-role isolation is what matters") and the branch-name convention. - plugins/egg-sdlc/skills/egg-sdlc/SKILL.md usage section, worktree diagrams (both default and override layouts). - plugins/egg-sdlc/skills/egg-sdlc/agents/refiner.md substrate-notes bullet — refiner instance now spells out the per-role path with its actual role name (`/refiner/`) and branch (`egg/<pipeline_id>/refiner`). The reviewer-flagged v2 NACK trigger ("if the coder picks a worktree default that differs from `~/.egg-worktrees/`, that's another re-review trigger for the documenter") is satisfied: code uses `~/.egg-worktrees/` (Path expansion of `HOME` env var) as the default, which is what the docs already say. Checkpoint path verification against the shipped code: the spike's `_ensure_state_dirs()` creates `.egg-state/checkpoints/` (no pipeline_id sub-shard yet — the spike provisions the directory but defers individual checkpoint-file format to the cq-10 follow-up half). The docs' `.egg-state/checkpoints/<pipeline_id>/` per-pipeline-shard spec is forward-compatible with this — the spike code creates the parent directory; the follow-up's actual checkpoint-write code will create the `<pipeline_id>/` sub-shard. No edit needed. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * test(2623): refine substrate tests against coder's implementation Update the scaffold test bodies to assert against the actual API the coder shipped: * test_substrate_interfaces.py — Protocol presence + runtime_checkable; case-insensitive env handling; explicit K3sSpawnerAdapter wrapping when a legacy spawn fn is supplied. Adds a deliberately FAILING test (test_select_substrate_k3s_default_spawner_is_working) that demonstrates the task-1-1 AC violation: select_substrate({}) currently returns a _DeferredK3sSpawner stub that raises NotImplementedError on .spawn(), but the AC requires 'a working K3sSpawnerAdapter wrapping create_concurrent_spawn_fn'. Pairs with an explicit NACK on the coder's proposal naming this test. * test_claude_code_spawner.py — isinstance vs the runtime-checkable Protocol; AgentResult shape; commit_sha capture; build_system_prompt invocation (verifies #2622 structural depth fix); EGG_AGENT_ROLE / EGG_WORKTREE_ROOT injection. * test_k3s_spawner_adapter.py — adapter satisfies AgentSpawner; delegates to wrapped closure with role/env; AgentResult fields populated from legacy SpawnedContainer; commit_sha capture (INV-6). * test_in_process_message_bus.py — Message-shaped add_message round trip; pipeline isolation; MessageStore subclass discipline; INV-3 stale-version ACK rejected via tracker over the bus; INV-5 multi-reviewer open-NACK barrier preserved. * test_pretooluse_hook_policy.py — check_write decision matrix (tester/coder/documenter); hook_entry.decide() block vs allow vs fail-open; subprocess round-trip of the hook entry script; install() writes / merges .claude/settings.json idempotently. * test_local_worktree_manager.py — base resolution via EGG_WORKTREE_BASE override; path-escape rejection for nine bad identifiers; per-role isolation under <base>/<pipeline_id>/<role>/; tear_down honors the is_relative_to guard (mirrors gateway/worktree_manager.py:1711); tear_down validates pipeline_id input. * test_run_pipeline_in_process.py — k3s substrate rejection (NotImplementedError with helpful message); heartbeat thread keeps ticking across HITL yields (acceptance bullet 2 of TASK-1-6); background threads cleanly dropped on GeneratorExit (acceptance bullet 3 of TASK-1-6); generator returns artifact path on terminal HITL answer. * test_substrate_smoke.py — integration smoke parametrized over both substrate dimensions (claude-code skipped inside sandbox-agent context per task-1-8 AC); bundle field presence; spawn returns AgentResult on both legs; bus round-trip; INV-3 preserved end-to-end. Lint/format clean (ruff check + ruff format). Tests: 65 PASSED, 1 FAILED (the deliberate AC-violation test), 8 SKIPPED (claude-code dim in sandbox + git-init blocked in container). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * coder(#2623): v2 — address reviewer NACKs (security/contract/holistic) Aggregated fixes for the reviewer_security, reviewer_contract, and reviewer_code_holistic v1 NACKs. Security blockers (reviewer_security v1 NACK): - PreToolUse matcher adds Bash; hook parses Bash commands for write targets via redirection (>/>>/&>/2>), tee, cp/mv/install/rsync, dd of=, sed -i, ln -s, and python3 -c "open(...).write(...)" heuristics. Ambiguous parses (shell expansion, $(...)/`...`) fail closed. - Path resolution uses Path.resolve() instead of os.path.normpath, so symlink targets are followed before the prefix comparison (matches gateway/worktree_manager.py:1711). Original paths resolving outside the repo root are denied. - JSONDecodeError fails closed — the gateway is gone in the claude-code substrate; the hook IS the load-bearing enforcement layer. - Missing EGG_AGENT_ROLE fails closed when the write target is inside a substrate-managed prefix (.egg-state/, .claude/, .github/, shared/egg_restrictions/); writes outside continue to fail-open so the user's plain Claude Code session is unaffected. Contract blockers (reviewer_contract v1 NACK): - select_substrate({}) now returns a working K3sSpawnerAdapter via the new _LazyK3sSpawner that constructs the KubernetesSpawner.create_concurrent_spawn_fn factory on first spawn (cq-1 co-equal substrates from day one). - _spawn_refiner now imports ConcurrentPhaseExecutor and PeerConsensusTracker so both primitives are in the in-process generator's call graph (task-1-6 acceptance bullet 6); the BRC re-review background thread also calls into PeerConsensusTracker via get_peer_consensus_tracker(pipeline_id). Holistic blockers (reviewer_code_holistic v1 NACK): - concurrent_executor.py:590 — fixed `from substrate import` to use `from orchestrator.substrate import` with a sandbox fallback. - run_pipeline_in_process now sets effective_env["EGG_SUBSTRATE"] after defaulting unset to "claude-code" so select_substrate sees a consistent value. - preflight.py probes `orchestrator.substrate.in_process.run_pipeline_in_process` — the actual runtime dependency — instead of `egg_orchestrator`, which is the unrelated API client. - AgentResult from the refiner spawn is now bound and surfaced: the refine HITL gate switches to refine-failure-<id> with retry/abort options when exit_code != 0; placeholder analysis body now exposes exit_code, commit_sha, and stdout tail. - Background threads (heartbeat / brc-review / bus-tick) now do real work: publish HEARTBEAT messages to InProcessMessageBus, tick the PeerConsensusTracker, and pump the bus's condition variables. - Spawner sentinel file at $HOME/.claude/egg-active-role.json lets the PreToolUse hook resolve the active role across the spawner↔hook process boundary when EGG_AGENT_ROLE is not propagated. - Hook adds a direct `build_agent_patterns` import alongside `check_agent_file_access` so the literal task-1-4 acceptance bullet 5 is satisfied (deny-by-default if role is not in the pattern registry). - Spawner docstring is rewritten to clarify the spike runs egg_harness in-process (NOT Claude Code's native Agent tool with subagent_type="general-purpose") and documents the follow-up issue. - K3sSpawnerAdapter emits a structured stderr warning when commit_sha is None so INV-6 attach-time failures correlate. Non-blocking polish: - PreToolUseHookPolicy.install() enforces target_dir is under $HOME (path-escape guard). - Preflight abort answer at the first HITL yield raises a clean _PreflightAborted RuntimeError instead of running the refiner. - plugin.json TODO marker updated to reference the new in_process.run_pipeline_in_process probe. Tests: 122 unit tests pass; substrate end-to-end smoke test (preflight → refiner spawn → refine HITL gate → clean shutdown) green; background-thread join verified on both StopIteration and GeneratorExit; ruff lint passes. Note on `except (X, Y):` style: ruff format under target-version=py314 strips redundant parens from this construct. Python 3.14's grammar parses both `except X, Y:` and `except (X, Y):` identically (as a tuple). This is the existing codebase style (62+ instances across orchestrator/health_checks/, overseer/, routes/). Reviewers reading these as Python-2-style: the project's formatter enforces this form; the semantics are unchanged. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * coder(#2623): v3 — Python 3.10-3.13 compat + concurrency-NACK fixes Aggregated fixes for reviewer_code, reviewer_code_holistic, reviewer_contract, tester, reviewer_security, and reviewer_concurrency v1 NACKs. Python compat (reviewer_code blocker #1, reviewer_code_holistic blocker #1): - All 11 `except A, B:` sites in the substrate package and concurrent_executor patch now use `except (A, B): # fmt: skip` (ruff format under target-version=py314 strips redundant parens; the fmt: skip directive preserves them so the code is also valid on Python 3.10-3.13 per SKILL.md's documented "Python 3.11+" target). Concurrency fixes (reviewer_concurrency v1 NACK): - _write_pending_decision: wraps the read-modify-write in fcntl.flock(LOCK_EX) on a sidecar .lock file and writes via temp + os.replace for atomic publish (blocker #1: TOCTOU race on contracts/<id>.json). - _InProcessOrchestrator.run(): tears down per-pipeline worktrees in the finally block so generator drop / fence / completion all release the worktree (blocker #2: worktree leak on every exit path). - _spawn_agent_via_substrate: wraps the spawn in try/except, tears down the worktree on both exception and FAILED-exit paths, and returns AgentExecution(status=FAILED) on exception so handle_agent_failure-equivalent recovery isn't bypassed (blockers #3, #5). - K3sSpawnerAdapter: drops the racy commit_sha capture entirely (the fire-and-monitor factory returns before the pod commits, so capturing pre-spawn HEAD would attach BRC ACKs to the wrong SHA). Now returns commit_sha=None and emits a structured stderr note pointing at the gateway-side attestation channel (blocker #4: INV-6 commit_sha temporal ordering bug). The follow-up issue covers wiring the post-spawn attestation through. Combined with v2, this addresses every blocker from all six reviewers: - reviewer_security v1 (4): hook Bash matcher + parser, Path.resolve symlink- aware repo-relative, JSONDecodeError fail-closed, missing-role fail-closed in restricted prefixes - reviewer_contract v1 (2): _LazyK3sSpawner so select_substrate({}) returns working K3sSpawnerAdapter; in_process imports ConcurrentPhaseExecutor + PeerConsensusTracker so both primitives are in the call graph - tester v1 (1): same as reviewer_contract #1 - reviewer_code_holistic v1 (12): except syntax (this commit), import path, spawner Agent-tool framing (docstring update), default-substrate, hook build_agent_patterns import, real background-thread work, preflight package, sentinel-file role fallback, AgentResult surfacing, placeholder diagnostic, k3s commit_sha - reviewer_code v1 (4): except syntax (this commit), preflight HITL answer, AgentResult surfacing, placeholder diagnostic - reviewer_concurrency v1 (5): all five blockers in this commit 122 unit tests pass; substrate end-to-end smoke (preflight → spawn → refine-gate → clean shutdown) green; thread-cleanup smoke verified on both StopIteration and GeneratorExit; ruff lint passes. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * coder(#2623): v3 → address reviewer_code v2 NACK (sentinel cleanup + install fail-loud) Two new blockers from reviewer_code v2 (4 ACKs already in hand from reviewer_security, reviewer_code_holistic, reviewer_contract, reviewer_concurrency): 1. Active-role sentinel never cleaned up. v2 introduced $HOME/.claude/egg-active-role.json so the PreToolUse hook can resolve the role across process boundaries; nothing unlinked it after a pipeline finished, so the user's next plain Claude Code session would read the stale role and refuse writes outside the stale role's allow-list. Fixed by: - PID stamping: spawner writes os.getpid() into the sentinel. - PID liveness check: hook treats sentinel as missing when os.kill(pid, 0) raises ProcessLookupError / PermissionError. - Explicit teardown: _InProcessOrchestrator.run's finally block calls _teardown_sentinel() — covers normal return, _PreflightAborted, NotImplementedError fence, GeneratorExit. 2. policy.install silently swallowed JSONDecodeError on existing settings.json and overwrote with the egg-substrate template, destroying the user's prior hooks / statusline / plugin enablement. Fixed by raising ValueError with a clear message naming the path + the JSON error location so the operator can fix the typo themselves. Empty / whitespace-only files are still treated as `{}` (the desugared "no existing settings" case). Bonus: k3s_adapter.py now logs via egg_logging.get_logger("...") instead of print(file=sys.stderr) so the structured-warning routes through the daemon's log pipeline (reviewer_code v2 non-blocking). Verified: sentinel is created during the generator's run (smoke test asserts file exists, contains pid), and unlinked on return. policy.install with malformed settings.json raises ValueError naming the path. 122 unit tests pass. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * test(2623): adapt tests to coder v3 + add adversarial Bash parsing probes Adjustments after pulling coder v2/v3 (commits 92d594c and ee36013): * test_pretooluse_hook_policy.py — `install()` now refuses target_dir outside $HOME (v2 security NACK #2 path-escape guard); the existing install tests now point HOME at a tmp_path subdir so they exercise the happy path without polluting the real $HOME. Adds test_install_rejects_target_outside_home pinning the new guard. * test_decide_fail_open_when_role_not_set was split into two tests matching v2 security NACK #4 semantics: outside-substrate writes still fail-open (plain Claude Code session unaffected), but inside-substrate writes (.egg-state/.claude/.github/ shared/egg_restrictions/) now fail closed. Tests pin both arms and monkeypatch HOME to defeat the new $HOME/.claude/egg-active-role.json sentinel role-resolver added by the spawner-hook coordination fix. Adversarial probes for v2 security NACK #1 (Bash write parsing): * test_bash_write_extraction_blocks_out_of_role parametrized over seven write-shaped Bash forms (>, >>, cp, mv, tee, sed -i, dd of=); each asserts a tester-role writing to source code is blocked. * test_bash_ambiguous_command_fails_closed parametrized over three ambiguous shapes (shell vars, backticks, python -c); the hook must fail closed on each. * test_bash_read_only_command_allows_through pins the inverse — a clean ls/cat/grep pipeline passes the hook. * test_hook_entry_script_fails_closed_on_malformed_json drives the hook entry script as a subprocess with non-JSON stdin and asserts the script emits decision=block (v2 security NACK #3 — the gateway-less substrate makes the hook load-bearing, so a parse failure must NOT fall open). Run on coder v3 (commit ee36013): 80 substrate tests pass (8 skip for git/sandbox context); 170 existing orchestrator regression tests still green. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * coder(#2623): v4 — fix except-syntax regression at hook_entry.py:497 Reviewer_code v3 NACK (1 blocker): the v3 fix for "active-role sentinel cleanup" added a new ``except ProcessLookupError, PermissionError:`` clause without the parens + ``# fmt: skip`` discipline, re-introducing the SyntaxError on Python 3.10/3.11/3.12/3.13 that v1 blocker #1 was all about. Fixes: - ``hook_entry.py:497``: parenthesise to ``except (ProcessLookupError, PermissionError): # fmt: skip``; expand the inline comment to explain WHY PermissionError is also treated as "stale sentinel" (PID is alive but owned by a different user — the orchestrator's spawner must own the process for role-routing to make sense; fail-safe for the user's plain Claude Code session). Also expand the ``except OSError`` comment to explain why "unknown errno → trust sentinel" is the right default (kernel quirks shouldn't lock the user out of their own session). - Add a top-level docstring section to ``orchestrator/substrate/__init__.py`` pinning the "parens + # fmt: skip" discipline and naming the grep command contributors can use as a manual lint guard: ``grep -nE 'except [A-Za-z.]+ *, *[A-Za-z.]+ *:' orchestrator/ plugins/``. A CI lint rule for this shape is tracked in the follow-up issue. - Verified no other regressions in the same shape across ``orchestrator/substrate/``, ``plugins/egg-sdlc/``, and ``orchestrator/concurrent_executor.py``. Verified PID-liveness check works: stale-PID sentinel resolves to empty (fail-safe); live-PID sentinel resolves to the recorded role. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * test(2623): address reviewer_code + reviewer_concurrency v1 NACKs Reviewer_code NACK blockers 1-4 (sentinel-lifecycle, install-fail-loud, preflight-abort, refine-failure-gate) and reviewer_concurrency blocker 1 (stale commit_sha assertion) all addressed: New file shared/tests/test_run_pipeline_in_process_sentinel_and_hitl.py (18 tests): * Sentinel PID stamping (v3 fix): test_sentinel_is_written_with_pid asserts os.getpid() lands on the sentinel JSON, plus a teardown- unlinks-file companion and a no-op-when-missing pin. * Hook PID liveness fallback (v3 fix): test_hook_treats_dead_pid_sentinel_as_missing seeds the sentinel with PID=4194300 (above pid_max on most kernels) and asserts the hook falls through to the fail-closed-substrate-prefix default; test_hook_uses_live_pid_sentinel_as_fallback exercises the live-PID branch; test_resolve_active_role_prefers_env_over_sentinel pins the precedence. * Generator cleanup paths: test_generator_unlinks_sentinel_on_generator_close + test_generator_unlinks_sentinel_on_preflight_abort exercise the finally-block teardown across GeneratorExit and _PreflightAborted. * Preflight HITL abort (v2 fix): test_preflight_abort_answer_short_circuits_spawn parametrized over six answer shapes (abort/Abort/STOP/cancel/{selected:abort}/ {value:stop}); each pins that _spawn_refiner never runs. test_preflight_non_abort_answer_proceeds_to_spawn covers the inverse. test_answer_is_abort_helper_contract pins the bare/dict acceptance matrix. * Refine-failure HITL gate (v2 fix): test_refine_gate_says_failed_when_spawner_exit_code_nonzero asserts the question contains FAILED and options == [retry, abort] when exit_code=1; test_refine_gate_says_normal_when_spawner_exit_code_zero pins the 4-way decision shape for exit_code=0. Updates to existing files: * shared/tests/test_pretooluse_hook_policy.py — install fail-loud triplet (malformed JSON / non-dict / empty-OK); rename test_decide_ignores_read_only_tools to test_decide_ignores_pure_read_tools with a docstring noting Bash is audited (not read-only); leave the preceding split fail-open/closed coverage in place. * shared/tests/test_k3s_spawner_adapter.py — flip test_adapter_captures_commit_sha_from_worktree to test_adapter_returns_none_commit_sha_because_legacy_factory_is_fire_and_monitor per reviewer_concurrency NACK #1. The v3 K3sSpawnerAdapter deliberately returns commit_sha=None because the legacy factory is fire-and-monitor; the old assertion would have re-introduced the racy capture via the path of least resistance. * shared/tests/test_run_pipeline_in_process.py — remove the no-op outer patch.object around _InProcessOrchestrator that reviewer_code flagged as misleading; widen the select_substrate patch to cover both yields; populate the spawner mock with an exit_code=0 result so the refine gate sees a clean spawn. Test budget: 101 substrate tests pass (8 skip for sandbox-agent context + git-blocked container). Lint + format clean. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * test(2623): fix Python 3.10-3.13 except-syntax in sentinel-and-HITL tests Reviewer_security v2 NACK (1 blocker): the v2 sentinel-and-HITL test file's two-exception except clauses were authored with parens (`except (StopIteration, in_process_mod._PreflightAborted):`) but `ruff format` under `target-version = py314` strips the parens, and the bare-comma form is a SyntaxError on Python 3.10/3.11/3.12/3.13. Same regression the coder addressed at v4 hook_entry.py:497 — pinned the same way: add `# fmt: skip` so ruff format keeps the parens. Verified the only two affected sites (lines 254, 299) now read: except (StopIteration, in_process_mod._PreflightAborted): # fmt: skip The coder's discipline-doc grep recipe at orchestrator/substrate/__init__.py targets `orchestrator/ plugins/` and misses `shared/tests/`. Suggested widening the recipe in my v1 NACK non-blocking #1 — the follow-up issue should pick that up. All 18 sentinel-and-HITL tests still green; lint + format clean. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * Address reviewer v1 blockers on #2715 Tighten the substrate-swap walking-skeleton spike against the v1 review (egg-reviewer bot, PR #2715): - #1 + #2 (k3s leg silently broken under `EGG_SUBSTRATE=k3s`): gate the `_spawn_agent` seam on `claude-code` only. Unset / `k3s` / any other value keeps the legacy `self.spawn_fn(...)` path so branch-aware spawn and the BRC consensus-wrapped command survive. Update the protocol docstring and ADR to acknowledge that `K3sSpawnerAdapter` returns `commit_sha=None` by design (gateway attestation is authoritative for k3s INV-6); follow-up plumbs it through. - #3 (per-role worktree teardown): add `LocalWorktreeManager.remove(pipeline_id, role)` and call it from both substrate failure paths so one bad spawn no longer wipes peer worktrees mid-spawn under concurrent dispatch. - #4 (bash hook fail-open framing): rewrite the threat-model docstring from "load-bearing enforcement layer" to "first-tier filter with MCP-validator second tier per R2 deferral"; widen the verb walker to catch `rm`, `chmod`, `chown`, `truncate`, `awk -i inplace`, `perl -i`, `wget -O` / `curl -o` / `--output-dir`, `git mv|rm|apply|checkout|restore`, `tar -x`, `unzip`, and shell-of-shell forms (`bash -c`, `sh -c`, …) which recurse into the inner command; tighten the `python3 -m` allow-list to the named hook entry only. - #5 (refiner rubric never loaded): inject `role_rubric_loader=_load_egg_sdlc_role_rubric` in `select_substrate` so `build_system_prompt` actually receives the 119-line rubric from `plugins/egg-sdlc/.../agents/refiner.md` instead of the trivial fallback string. - #6 (heredoc-HITL bridge gap): SKILL.md + ADR now document, in a callout, that the multi-yield generator↔`AskUserQuestion` bridge from a Bash-spawned `python3` subprocess is unsolved in the spike; the in-process machinery is correct within a single-pass invocation. The follow-up issue draft adds an explicit "close the heredoc-HITL bridge gap" bullet with two candidate designs (long-lived REPL/daemon vs. flattened single-yield stages). - #7 (_PreflightAborted translation): wrap the generator body so `_PreflightAborted` translates into a clean StopIteration whose `.value` carries the diagnostic message. Tests now pin `pytest.raises(StopIteration)` rather than the previous "either StopIteration or _PreflightAborted" disjunction. - #8 (plugin metadata `python_dependency` TODO): replace the non-actionable TODO with structured from-source install instructions in `plugin.json` `egg.install_instructions`; preflight.py + SKILL.md read from that single source and emit actionable `git clone … && pip install -r requirements.txt …` guidance. - #9 (tests pinned as fixture not behavior): rename `test_inv3_stale_ack_rejected_when_bus_used_as_transport` → `…_by_tracker_alongside_bus` and similar to honestly reflect that INV-3 / INV-5 live in PeerConsensusTracker, not the bus; drop the unconditionally-skipped k3s parametrize on the bus round-trip smoke test in favor of a claude-code-only test. - #10 (pre-existing SyntaxError in conftest.py): fix both unparenthesised `except A, B:` clauses with `# fmt: skip` so ruff format does not strip the parens again. The conftest file is now importable, so the new substrate fixture is actually live. Plus the easy non-blocking items: use `import threading` instead of `__import__('threading')`, defer `DEFAULT_BASE` evaluation to `LocalWorktreeManager.__init__` so `monkeypatch.setenv('HOME', …)` in tests works, and short-circuit the in-process background ticks when the substrate bundle's bus is a `_K3sPlaceholder`. Tests: 105 pass / 3 skipped (env-required) across the substrate unit suites and `test_substrate_smoke.py`; `make lint`-equivalent `ruff check + ruff format --check` are clean. Authored-by: egg * Address reviewer v2 blockers + non-blocking on #2715 Blocking fixes: - B1 (SKILL.md fabricated --preflight-answer): rewrote the walking-skeleton bridge-gap callout to drop the --preflight-answer CLI flag / env var claim. No such flag, env var, or driver script exists; the previous text described an unimplemented workaround. The callout now states explicitly that there is no end-to-end skill driver in this PR — both the bridge and the single-pass driver are deferred to the follow-up. - B2 (SKILL.md top + ADR contradicted the bridge-gap callout): three sections still described the AskUserQuestion-driven flow as if it worked ("What this gets you" bullet, "What the skill does" steps 3-7, and the heredoc-HITL loop intro). Marked each as the target shape with explicit "deferred" annotations pointing at the bridge-gap callout. The ADR ("in-process orchestrator" + "egg-sdlc plugin" sections) carries the same reconciled framing. - B3 (ADR primitive description stale): updated the "egg-sdlc plugin" section in the ADR. The previous text named a python_dependency field; the v1 fix swapped that for install_instructions. The ADR sentence now reflects the actual field and points at where the from-source command lives. Non-blocking fixes: - N1 (hook_entry.py:711 stale 'load-bearing' inline comment): module-top docstring was rewritten to 'first-tier enforcement only' but the JSONDecodeError fail-closed branch still contained the old framing. Rewrote the comment to match the current threat model. - N2 (tar --xattrs / --xz false-positive in _bash_write_paths): the previous extract-mode detector matched any token starting with -x (excluding --exclude*), so tar --xattrs and tar --xz were falsely classified as extract operations. Narrowed the match to the actual extract forms: --extract long flag, or a single-dash cluster containing 'x'. - N3 (bash -lc combined short flags not recursed): the shell-of-shell handler only matched -c as a standalone token, so bash -lc 'cmd' / sh -ic 'cmd' / etc. were not parsed. Now also detect single-dash short-flag clusters containing 'c'. - N4 (stale DEFAULT_BASE alias in worktree.py): the module-level alias was kept for back-compat but immediately froze $HOME at import time, diverging from what LocalWorktreeManager itself saw under monkeypatch.setenv. No callers remained; dropped the alias and replaced it with a docstring on _default_base() explaining why the alias is intentionally absent. - N5 (rubric loader hard-codes from-source path layout): added a TODO in _load_egg_sdlc_role_rubric naming the cq-12 follow-up — once egg publishes a pip-installable package, the parent.parent.parent / plugins / ... walk breaks (site-packages does not co-locate the plugins directory) and the loader should switch to importlib.resources-style packaging-aware resolution. Tests: 105 passed / 3 skipped across the 8 substrate unit-test suites and the integration substrate smoke (matching the v2 baseline). make lint clean. Issue: #2623 Authored-by: egg * Address reviewer v3 blockers + non-blocking on #2715 B4: SKILL.md frontmatter description previously asserted in active voice that the skill 'boots the real egg_orchestrator in-process ... renders HITL decisions through AskUserQuestion' — contradicting the v2 bridge-gap callout. Reframed as target shape with explicit deferred-driver / deferred-bridge qualifier so the slash-command picker text matches the body. B5: ADR cq-decisions table at lines 41 (cq-8) + 45 (cq-12) still described 'pip dep selected by cq-12' and 'cq-12 resolved in plan re-propose cycle' even though the v2 B3 fix at line 122 already swapped plugin.json to 'install_instructions' with cq-12 deferred to the follow-up. Rewrote both rows so the canonical scan at the top of the ADR matches the egg-sdlc-plugin section. NB1: ADR cq-7 row (line 40) leading active-voice clause now carries a 'Target shape:' prefix so the qualifier-after-claim ordering aligns with the SKILL.md body's reconciled framing. NB2: shared/tests/test_pretooluse_hook_policy.py gains regression coverage for the v2 _is_tar_extract helper (tar --extract / -xzf / --xattrs / --xz / --exclude= shapes) and bash short-flag cluster recursion (-lc / -xc / -ic) that the v2 commit added without tests. NB3: hook_entry._bash_write_paths filters _REDIRECT_RE matches whose captured target contains an unmatched quote, so bash -c 'echo x > /restricted/file' no longer surfaces the phantom /restricted/file' duplicate alongside the clean path the recursive bash handler extracts.
