Context

BRC consensus today depends on the agent re-entering a blocking
egg-orch message wait-loop between every event. That re-entry is a
seam the model can fall out of by emitting a final assistant
message instead of re-entering the wait. Claude usually re-enters;
qwen3.7-max does not (#2906) — it exits success=True after one
match, the wrapper sees no CONSENSUS_CONFIRMED, the 3-restart cap
trips (#2806), and the pipeline FAILs after ~$1 and ~20 min of
churn. Prompt-only mitigations narrow the seam for one model; the
seam itself exists for every model (lineage: #2323, #2064, #2482,
#2036, #1995, #2451).

Changes

Reframe consensus-agent execution from a long-lived participant
that holds blocking waits into a deterministic wrapper-driven
event pump
that invokes the agent one-shot per actionable event,
with continuity carried by a durable per-role memory file. Lands
in six linear slices behind EGG_BRC_EVENT_PUMP (default false
until slice-4):

  1. slice-1 — Foundations. New egg-orch brc next-action,
    brc get-state, brc list-blocking, phase get-context CLI
    subcommands. Durable BRC memory artifact at
    .egg-state/agent-outputs/<role>/brc-memory.md with
    action-scaffolded writes into brc_ack / brc_nack handlers,
    atomic writes via promoted _persist_atomic_template,
    last_reviewed_commit_sha per producer in the schema,
    fail-closed path construction. Gated by
    EGG_BRC_MEMORY=write-only (writes accumulate; reads land
    in slice-3). Purely additive — zero behavior change.
  2. slice-2 — Event-pump wrapper. Rewrite
    orchestrator/consensus_wrapper.py as a deterministic event
    pump gated by EGG_BRC_EVENT_PUMP. Drop the 3-restart cap;
    replace with idle/no-progress safety budget. Migrate the
    heartbeat (Overseer flags BRC reviewers/testers as stalled when they're correctly blocked in mcp__brc__wait_loop (implement-phase false positive) #2036) and gateway-session keep-alive (Orchestrator heartbeat-session lookup fails: container_id missing slice-N segment for non-coder roles #2451) from
    the agent-side handler into the wrapper's blocking wait.
    Heartbeat payload carries slice_id from EGG_SLICE_ID
    (regression guard). Verification is unit-test-only — no
    in-process test double can drive a deployed pod end-to-end
    (the pod-injection avenue was ruled out per Expand integration test coverage #2474); true
    E2E deferred to slice-4 via the egg_stack real-pod
    fixture. Old path retained verbatim alongside.
  3. slice-3 — Delta + prompt collapse. Wire per-event
    invocation to hand the agent the memory delta plus the full
    git log {last_reviewed_commit_sha}..HEAD --not origin/{base_branch} -p
    delta per producer (NOT just orchestrator-side
    changed_artifacts — per REVIEWER-SYNC.md the re-review must
    audit the full delta as a fresh review). Strip the
    STAY-ALIVE / wait-loop / cursor-threading guidance from
    _build_brc_preamble and mission.md; replace with a lean
    event-handler contract. Sandbox image rebuilt + agent pod
    restarted BEFORE slice-4 flag flip.
  4. slice-4 — Flag flip + delete old path. Flip the
    EGG_BRC_EVENT_PUMP / EGG_BRC_MEMORY defaults to on, gated on
    the slice-2 / slice-3 unit + BRC in-process regression suites
    passing on the new default; delete the capped-restart bash, the
    _RECOVERY_SYSTEM_PROMPT, the SSE machinery, and the
    agent-side wait_loop heartbeat code. Rollback plan: revert
    slices 1–3 via git revert if production traffic regresses. The
    qwen3.7-max qwen3.7-max BRC agents end their agentic loop early (success=True) without reaching CONSENSUS_CONFIRMED → consensus-wrapper restart churn #2906 k3s spike that previously validated this
    end-to-end was removed (qwen route unavailable in k3s;
    Claude-route E2E deferred to Rewrite TestCredentialIsolation as k3s-native (currently skipped under k3s) #2585).
  5. slice-5 — Additive CLI prose plumbing + 2 new BRC
    subcommands.
    Add stdin / --reason-file / --summary-file
    / --files-reviewed-file plumbing to
    consensus propose --summary, consensus ack --reason,
    consensus nack --reason, consensus withdraw --reason
    (docs: steer agents to the structured contract tool, not Bash-composed egg-contract #2741 regression guard). Add egg-orch brc resolve-obligation
    and egg-orch brc read-peer-artifact CLI subcommands the
    slice-6 deletion depends on. Argv kept as fallback during
    transition (deprecation warning).
  6. slice-6 — MCP → CLI deletion. Delete the 28 agent-facing
    MCP tools (~1,515 LOC across 7 namespace files + the 4
    infra files + server.py), the SYSTEM_PROMPT_NUDGE, and the
    MCP registration block in shared/egg_agent/client.py:299-353
    INCLUDING the EGG_MCP_TOOLS env flag at :311 (no orphan
    flag). Retire tests/tools/test_mcp_cli_drift.py. Migrate the
    MCP E2E test so the agent's first action is consensus ack/nack via stdin/file (preserves SDK-spawn exercise).
    Verify per-event wall-clock latency within 5%.

Impact

Operator-facing: the BRC consensus subsystem becomes
model-portable — any agent that exits naturally after handling
one event reaches CONFIRMED, instead of needing prompt nudges to
keep re-entering an in-process wait. Cost-per-phase drops because
restart churn disappears, replaced by short bounded per-event
invocations that hit the prefix cache (≥ 60-min TTL on both
routes per WS7 closure). Net code deletion: the capped-restart
template, the SSE machinery, the recovery system prompt, the 28
MCP tool schemas, the EGG_MCP_TOOLS flag, the cursor-threading
guidance, and the agent-side heartbeat all go away. The agent
primitive (pod / worktree / SDK / permissions / restrictions) is
untouched.

Tasks:

  • task-6-1: Delete the 7 MCP tool namespace files at sandbox/egg_agent_tools/tools/{brc,checkpoint,message,phase,progress,sdlc,task}.py (~1,515 LOC). Delete the 4 infrastructure files (sandbox/egg_agent_tools/tools/{__init__,_common,_registry,_tool_compat}.py). Delete the SYSTEM_PROMPT_NUDGE constant at sandbox/egg_agent_tools/server.py:61 and the build_sandbox_mcp_server factory in the same file. The shared handler layer at sandbox/egg_agent_tools/handlers/*.py is RETAINED — both surfaces collapse to one (the CLI / direct handler path), not zero. server.py is reduced to whatever else lives there (only the MCP-specific exports — verify via grep at implement-time; if no non-MCP exports remain, delete server.py too).
    • Acceptance criteria: rg 'from egg_agent_tools.tools|build_sandbox_mcp_server|SYSTEM_PROMPT_NUDGE' across the tree returns zero matches; the handler layer at sandbox/egg_agent_tools/handlers/*.py unchanged; deletion lands in a single coder commit.
  • task-6-2: Delete the MCP registration block in shared/egg_agent/client.py:299–353: the EGG_MCP_TOOLS env-flag gate at :311 (no orphan flag — per architect v2 slice-6 goal "INCLUDING the EGG_MCP_TOOLS env-flag check at line 311"), the build_sandbox_mcp_server import at :316, the mcp_servers = build_sandbox_mcp_server() call at :319, the options.mcp_servers = {...} assignment at :323, and the SYSTEM_PROMPT_NUDGE append at :332. The operator-facing orchestrator/mcp_server.py is out of scope — confirm via grep that nothing in the deletion accidentally touches it.
    • Acceptance criteria: shared/egg_agent/client.py no longer references MCP tools or the EGG_MCP_TOOLS env flag; client.py options no longer set mcp_servers (or sets only the operator-facing orchestrator/mcp_server.py if separately registered — confirm by grep); rg 'EGG_MCP_TOOLS' across the tree returns zero matches (no orphan references).
  • task-6-3: Retire tests/tools/test_mcp_cli_drift.py (delete; the MCP↔CLI drift contract no longer applies since the MCP surface is gone). The shared handler layer keeps both surfaces honest in spirit; the formal drift suite is retired.
    • Acceptance criteria: tests/tools/test_mcp_cli_drift.py deleted; rg 'test_mcp_cli_drift' across the tree returns zero matches; existing test suite remains green.
  • task-6-4: Migrate integration_tests/test_sandbox_mcp_tools_e2e.py to exercise the CLI surface. The architect v2 slice-6 goal specifies the test must "preserve the SDK-spawn exercise rather than collapsing to direct-handler" — the agent's first action becomes egg-orch consensus ack/nack via stdin/file (using the slice-5 prose plumbing from TASK-5-1). Where the original tests assert the MCP-tool surface (schema, registration, system-prompt-nudge), replace with equivalent assertions: subcommand exists, --help mirrors the expected fields, stdin/file round-trip works. Where they assert handler-layer behaviour, simplify to direct handler invocation. Migrate tests/sandbox/egg_agent_tools/test_server.py separately — the MCP-registration test goes away with the MCP server.
    • Acceptance criteria: integration_tests/test_sandbox_mcp_tools_e2e.py exercises the CLI surface AND the SDK-spawn end-to-end (not just the handler layer); tests/sandbox/egg_agent_tools/test_server.py no longer asserts MCP registration; both files pass under make test; rg 'from sandbox.egg_agent_tools.tools' in test paths returns zero matches.
  • task-6-5: Documenter: update docs/architecture/sandbox.md, docs/reference/agent-tools.md (locate via Grep docs/ for "MCP tools" / "SYSTEM_PROMPT_NUDGE" / "EGG_MCP_TOOLS"), and the project CLAUDE.md Quick Reference if it references the agent MCP surface. Cover: the MCP tool surface is retired in favour of the CLI; the EGG_MCP_TOOLS env flag is no longer recognised; the shared handler layer at sandbox/egg_agent_tools/handlers/*.py backs both today (CLI only after this slice); the operator-facing orchestrator/mcp_server.py is unaffected and remains the operator's MCP surface. The documenter role has direct write access to CLAUDE.md via the DEFAULT_DOCS_GLOBS **/*.md pattern at shared/egg_restrictions/patterns.py:177-181 — no staging workaround needed (reviewer_plan non-blocker).
    • Acceptance criteria: All references to the agent-side MCP tools updated to the CLI surface; EGG_MCP_TOOLS references removed; orchestrator/mcp_server.py references preserved; CLAUDE.md edited in place (if applicable) — no .egg-state/agent-outputs/ staging detour.
  • task-6-6: Per-event wall-clock latency verification at integration_tests/test_mcp_to_cli_latency.py (directly under integration_tests/; local_pipeline/ does not exist). Baseline-capture strategy: TASK-5-7 captures the baseline DURING slice-5 (before slice-6's deletions land) on the still-live MCP surface using the egg_stack fixture and commits the result to .egg-state/agent-outputs/latency-mcp-baseline.json. TASK-6-6 (this task) drives the SAME consensus shape on the post-deletion CLI-only surface — also via egg_stack (session-scoped at integration_tests/conftest.py:340) — reads the slice-5-captured baseline, and asserts the comparison. Both measurements use the same real-LLM tier — the only delta is the tool surface. Latency regression budget: ≤ 5%. On regression > 5%, slice-6 surfaces a structured OVERSEER_ALERT priority medium with the measured delta for human review (the fallback decision is whether to ship the persistent egg-orch daemon per architect od-5).
    • Acceptance criteria: latency-mcp-baseline.json exists under .egg-state/agent-outputs/ at slice-6 entry (captured by TASK-5-7); the post-deletion measurement is captured to .egg-state/agent-outputs/latency-mcp-vs-cli.json; assertion fails only if regression exceeds the 5% budget; on failure the test surfaces a structured OVERSEER_ALERT priority medium with the measured delta. No vendored MCP source tarball. No ScriptedProvider import or reference. Test gated via egg_stack (skips if _kubectl_available() returns False).

Test Plan

Per-slice automated coverage:

Manual verification:

  • slice-3 pre-merge: sandbox image rebuilt + agent pod restarted
    so the new mission.md is reachable in the pod BEFORE slice-4
    flag flip.
  • slice-4 pre-flag-flip: human inspects spike output
    (brc-memory content for reasoning fidelity;
    last_reviewed_commit_sha updated per producer; cost-per-phase
    delta vs restart-churn baseline) and
    consents to default-on flip via PR review.
  • slice-6 pre-merge: human verifies no in-flight pipelines are
    mid-run against pre-slice agents; gate deploy on drain or
    cancel.

Manual Steps

Pre-merge:

  • slice-3: sandbox image rebuilt + agent pod restarted BEFORE
    slice-4's flag flip (the new mission.md is the slice-4
    assumption; if pods are still running the old image when the
    flag flips, the event-pump path will reference STAY-ALIVE
    semantics that have been deleted from the preamble).
  • slice-4: human review of spike output (memory content,
    last_reviewed_commit_sha correctness, cost delta)
    before the EGG_BRC_EVENT_PUMP default flips to true.
  • slice-6: confirmation that no
    in-flight pipelines exist before deploy (MCP tools are deleted
    so an old wrapper that still injects them starts with no MCP
    server registered).

Post-merge:

  • slice-4: monitor 24 h of production BRC traffic for any
    "Agent exited without BRC consensus" entries; fall back via
    EGG_BRC_EVENT_PUMP=false deployment env if seen. Rollback
    path for full spike falsification: git revert slices 1–3 (no
    production traffic touched the new path because the flag
    stayed off until slice-4).
  • slice-6: monitor latency dashboards 24 h for per-event
    wall-clock regression beyond the 5% budget.

…r branch

The slice-4 coder branch was created based on main but the slice-4
parent at origin/egg/issue-2908-impl2/slice-4 has the slice-1, slice-2,
and slice-3 implementation work that slice-4 builds on. Merge it in
before doing task-4-1 / task-4-2.

Conflicts resolved in orchestrator/routes/pipelines.py and
orchestrator/tests/test_pipeline_prompts.py — both in the BRC
preamble dual-role banner. The coder-owns-tests refinement (#2936)
that landed on main and the event-pump banner collapse from
slice-3 task-3-3 of #2908 both touch the dual-role banner text.

Resolution: keep slice-3's event-pump structure (no wait-loop filter
allowlists in the preamble — the wrapper drives invocation) and
layer in the coder-owns-tests semantics on top: the tester's first
invocation does ORIENT/PREPARE only; the wrapper re-invokes it on
the coder's CONSENSUS_PROPOSE; it does its producer WORK (review +
harden the coder's tests) + PROPOSE + ACK/NACK in that single
invocation.

…ORY defaults

Slice-4 task-4-1 makes the event-pump wrapper the production default
by flipping two env-flag defaults:

* ``EGG_BRC_EVENT_PUMP`` flips from unset→OFF (legacy) to unset→ON
  (event-pump). Setting ``EGG_BRC_EVENT_PUMP=false`` (or
  ``0`` / ``no`` / ``off``, case-insensitive) keeps the legacy
  capped-restart template available for a one-release rollback
  window. Unrecognised tokens fall through to event-pump so a typo
  cannot silently downgrade the production path. Slice-4 task-4-2
  will delete the legacy template entirely and the env flag with it.

* ``EGG_BRC_MEMORY`` flips from unset→``off`` (slice-1 inert) to
  unset→``full`` (event-pump composer reads memory by default).
  Setting ``EGG_BRC_MEMORY=off`` is the one-release rollback escape
  hatch. Unknown values still fail-safe to ``off`` (the fallback
  target stays restrictive — an undocumented value is a
  misconfiguration signal, NOT a write-bearing default to mask).

Files touched:

* ``orchestrator/consensus_wrapper.py``:
  - ``_event_pump_enabled()`` default flipped; falsy-token allowlist
    captures rollback path; docstring + module-level reframe updated.
  - Wrapper template's inline ``EGG_BRC_MEMORY:-off`` → ``...:-full``
    so the wrapper's invocation of ``event_prompt.py`` inherits the
    new default even on shells that don't export the var explicitly.

* ``sandbox/egg_agent_tools/handlers/brc_memory.py``:
  - ``get_memory_mode()`` defaults to ``MODE_FULL``; new
    ``MODE_DEFAULT`` constant pins the contract.

* ``orchestrator/routes/event_prompt.py``:
  - CLI ``memory_mode`` default flipped from ``"off"`` to ``"full"``.

* Tests updated to match the new defaults:
  - ``orchestrator/tests/test_consensus_wrapper.py``:
    ``TestEventPumpTemplateSelection`` rewritten — unset-env now pins
    event-pump, ``EGG_BRC_EVENT_PUMP=false`` pins legacy.
    ``TestBuildConsensusWrappedCommand``,
    ``TestConsensusWrapperBehavior``, ``TestBufferOverflowDetection``,
    ``TestEventDrivenWait``, ``TestSSESigtermGrace`` gain an autouse
    ``_force_legacy_template`` fixture that engages the rollback
    escape hatch so they continue to drive the legacy template.
    Slice-4 task-4-2 deletes the entire fixture + these classes
    alongside the legacy template.
  - ``tests/sandbox/egg_agent_tools/test_handlers_brc.py``:
    renamed ``test_unset_defaults_to_off`` → ``test_unset_defaults_to_full``;
    the unset-env pin now asserts the memory file is written.
  - ``orchestrator/tests/test_compose_event_prompt.py``: docstring
    note that ``write-only`` is the rollback target, not the default.

Verified manually with Python smoke tests that the flag-flip works
for unset, truthy, and the full falsy-token allowlist
(``false`` / ``0`` / ``no`` / ``off`` / case variants), and that
``EGG_BRC_MEMORY=writeonly`` (typo) still fails safe to ``off`` with
a warning while ``EGG_BRC_MEMORY=full`` and unset both enable
writes + reads.

# Conflicts:

Rewrite docs/architecture/orchestrator.md "BRC Consensus Wrapper" section
(renamed from "BRC Event-Pump Wrapper (slice-2, behind EGG_BRC_EVENT_PUMP)")
to describe the post-deletion steady state. Event-pump is now the only
consensus-wrapper path; the legacy capped-restart template and the
agent-side heartbeat / keep-alive path were removed in slice-4 task-4-2.

Changes:
- docs/architecture/orchestrator.md
  - Renamed section to "BRC Consensus Wrapper"; updated anchor link
    from #brc-event-pump-wrapper-slice-2-behind-egg_brc_event_pump.
  - Replaced the slice-2 caveat blockquote with a four-slice rollout
    summary that names the deleted symbols (_CONSENSUS_WRAPPER_TEMPLATE,
    _RECOVERY_SYSTEM_PROMPT, SSE consensus.reached, MAX_CONSENSUS_RESTARTS).
  - Reframed "Why a new wrapper template" → "Why the wrapper drives the
    loop"; rewrote in past tense so the doc reads as if the event-pump
    has always been the only model.
  - Rewrote "Wrapper-side heartbeat (#2036 migration)" and
    "Wrapper-side gateway-session keep-alive (#2451 migration)" with
    "completed in slice-4" qualifier; described agent-side deletion.
  - Rewrote "Idle / no-progress safety budget" to drop the comparison
    table with the legacy 3-restart cap; replaced with a single
    behaviour table for EGG_BRC_IDLE_BUDGET_MIN.
  - Added new "Rollback plan" subsection documenting git revert of
    slice-4 → slice-3 → slice-2 → slice-1 in reverse-merge order, the
    integration check operators must run, and the partial-revert
    interaction (reverting only slice-4 restores the dual-emission
    state).
  - Renamed "Slice-2 verification stance — unit-test-only" to
    "Verification stance — unit-test-only"; explained that the
    snapshot tests pinning the byte-for-byte legacy template emission
    were retired in slice-4 task-4-3.
  - Renamed "BRC Per-Event Prompt Composer + Preamble Collapse
    (slice-3)" to drop the slice marker; reframed "Flag mapping" to
    "What's gated by what" since EGG_BRC_EVENT_PUMP no longer gates
    anything.
  - Updated EGG_BRC_MEMORY table: full is now the slice-4 default;
    write-only is the opt-in regression path.
  - Updated env vars table: EGG_BRC_EVENT_PUMP is a deprecated no-op
    pointing at the rollback plan; EGG_BRC_IDLE_BUDGET_MIN is no
    longer gated on EGG_BRC_EVENT_PUMP=true.

- docs/guides/concurrent-execution.md
  - Replaced the slice-2 "two emission paths" caveat with a single
    post-deletion summary linking to the new orchestrator.md section.
  - Rewrote the "Consensus Wrapper" body to describe the deterministic
    event-pump loop (steps 1–6) as the only path; removed
    MAX_CONSENSUS_RESTARTS-based restart cap, the recovery system
    prompt, and the final-consensus-check restart cycle.
  - Updated the configuration table: dropped `max_restarts` row;
    added EGG_BRC_IDLE_BUDGET_MIN; updated transient-crash recovery
    paragraph to reference the idle/no-progress budget instead of
    the deleted MAX_CONSENSUS_RESTARTS hard cap.

- docs/architecture/README.md
  - Updated the cross-link card to point at the renamed section and
    summarise the slice-4 deletion + rollback plan.

Cross-links to docs/architecture/brc-memory.md (slice-1) retained
throughout. The wait-side companion at agent-wait-patterns §10 is
referenced from each cross-link card.

Satisfies contract task-4-4. Acceptance: doc reads as if the event
pump has always been the only model; legacy-path caveats removed;
cross-links present; rollback plan documented; markdown renders
clean (no conflict markers; section anchors resolve).
…nd agent-side heartbeat

Slice-4 task-4-2 collapses ``consensus_wrapper.py`` onto the
event-pump template that slice-2 introduced and slice-3 wired the
per-event composer into. The event-pump is now the only production
path; rollback under a regression is a ``git revert`` of slices 1-3
per the PR body, not an env-flag flip.

Deleted from ``orchestrator/consensus_wrapper.py``:

* ``_CONSENSUS_WRAPPER_TEMPLATE`` (the ~600-line legacy
  capped-restart bash template).
* ``_RECOVERY_SYSTEM_PROMPT`` and ``_RECOVERY_USER_PROMPT`` — the
  restart-time recovery prompts.
* The SSE ``consensus.reached`` curl path (issue #1897) that lived
  inside the legacy template — the event-pump uses
  ``egg-orch message wait-loop`` instead.
* ``MAX_CONSENSUS_RESTARTS`` (issue #2806) and its companion
  constants ``MAX_READY_POLL_CYCLES``,
  ``TRANSIENT_RESTART_BACKOFF_INITIAL``,
  ``STARTUP_FAILURE_WINDOW_SECONDS``. The idle/no-progress safety
  budget (env ``EGG_BRC_IDLE_BUDGET_MIN``, default 30 min) is the
  replacement liveness ceiling.
* ``_event_pump_enabled()`` — the ``EGG_BRC_EVENT_PUMP`` env-flag
  read. The flag is now silently inert; operators with it lingering
  in k8s manifests can leave it set to either truthy or falsy and
  still get the event-pump template.
* The legacy-template branch in ``build_consensus_wrapped_command``,
  which is now a thin alias for ``build_event_pump_wrapped_command``.

Preserved by relocating into ``_EVENT_PUMP_WRAPPER_TEMPLATE`` (per
task-4-2 acceptance, "Keep ``is_buffer_overflow`` /
``is_transient_crash`` / ``is_startup_failure`` classifiers"):

* ``is_buffer_overflow()`` — Claude Agent SDK 1 MiB JSON reader
  overflow detector (#2804).
* ``is_transient_crash()`` — signal-based exits (134, 136, 137,
  139, 255).
* ``is_startup_failure()`` — exit 1 within a 30 s startup window.
* ``STARTUP_FAILURE_WINDOW_SECONDS`` — kept as a bash-scope shell
  variable inside the template (was a Python module constant).

The classifiers are not yet wired into the event-pump's
``propose|ack|nack`` agent-invocation failure path (which uses
``AGENT_FAIL_STREAK`` + idle-budget escalation today); they live
as named helpers for future revisions.

Deleted from ``sandbox/egg_agent_tools/handlers/message.py``:

* ``_WAIT_LOOP_HEARTBEAT_INTERVAL_SECS`` — the 60-s cadence
  constant.
* ``_default_emit_wait_loop_heartbeat`` — the agent-side
  ``WAITING_FOR_EVENT`` / ``WORKING`` heartbeat emitter (#2036).
* ``_start_wait_loop_heartbeat`` — the threaded periodic-tick
  helper.
* The per-iteration ``emit_hb`` / ``stop_hb`` calls inside
  ``message_wait_loop``, including the ``try/finally`` block that
  drove the final ``WORKING`` beat on wait exit.

The event-pump wrapper now owns both heartbeat liveness (#2036) and
slice-scoped gateway-session keep-alive (#2451) via the wrapper-
owned ``start_background_heartbeat`` subshell. ``message_heartbeat``
(the explicit handler invoked by ``egg-orch message heartbeat``) is
unchanged — the wrapper calls it.

Test updates:

* ``orchestrator/tests/test_consensus_wrapper.py``: deleted the
  ``TestBuildConsensusWrappedCommand`` / ``TestConsensusWrapperBehavior``
  / ``TestBufferOverflowDetection`` / ``TestEventDrivenWait`` /
  ``TestSSESigtermGrace`` classes (and the ``_force_legacy_template``
  fixture that fed them). The buffer-overflow / SSE / capped-restart
  surfaces they covered no longer exist. The event-pump classes
  (``TestEventPumpTemplateSelection`` and siblings) cover the new
  production path; ``TestEventPumpTemplateSelection`` is reworked
  to pin the post-task-4-2 invariant that ``EGG_BRC_EVENT_PUMP`` is
  silently inert (any value, including ``false`` / ``0`` / ``no``
  / ``off``, emits the event-pump template).
* ``orchestrator/tests/test_consensus_wrapper_anchor.py``: deleted
  in full — every test pinned ``_RECOVERY_SYSTEM_PROMPT`` /
  ``_CONSENSUS_WRAPPER_TEMPLATE`` symbols that no longer exist.
* ``orchestrator/tests/test_brc_nack_iteration.py``: removed
  ``TestConsensusWrapperNackFeedback`` (4 tests) that pinned the
  legacy recovery prompt's NACK-feedback placeholder + helper. The
  equivalent event-pump assertion lives in
  ``orchestrator/tests/test_compose_event_prompt.py``.
* ``tests/sandbox/egg_agent_tools/test_handlers_message.py``:
  removed ``TestMessageWaitLoopHeartbeat`` (16 tests) that pinned
  the agent-side heartbeat path. ``TestMessageHeartbeat`` (the
  explicit handler tests) is unchanged.
* ``integration_tests/regression/test_brc_concurrency.py``:
  updated the slice-2 verification-stance docstring to reflect the
  slice-4 post-deletion steady state (E2E deferred to #2585 via
  ``egg_stack``; in-process tracker coverage unchanged).

Defensive grep assertions all return zero matches on
``orchestrator/consensus_wrapper.py``:

  rg 'consensus\.reached|sse_url|_RECOVERY_SYSTEM_PROMPT|MAX_CONSENSUS_RESTARTS' \
      orchestrator/consensus_wrapper.py
  # → 0 hits

Smoke-verified that the event-pump template is emitted regardless of
``EGG_BRC_EVENT_PUMP`` value, that the three classifiers survive in
the event-pump template, and that the deleted agent-side heartbeat
helpers are no longer importable from ``handlers.message``.

Five blocking findings + three non-blockers from reviewer_code's v1
NACK on PR-proposal v1. Address all five blockers; defer the
non-blockers (env-var coordination is gated on coder task-4-1 / task-4-2
landing first).

Blocker 1+2+3 — restored post-#2936 coder-owns-tests content in
docs/guides/concurrent-execution.md (the v1 proposal overwrote the
post-#2936 wording when I copied the slice-4 base, which predates the
#2936 merge):
- §"HANDOFF" table row example: "Coder can't push test files → HANDOFF
  to tester" → "Tester can't push a .github/ CI fix → HANDOFF to coder
  with the required end-state" (matches docs/reference/agent-roles.md).
- §"Worked Example: Role-Boundary Handoff" rewrite: drop the
  reinstated pre-#2936 coder→tester test-handoff example, restore the
  post-#2936 tester→coder .github/-staging example, and keep the
  explicit lead sentence "the coder→tester test handoff that used to
  live here is gone: the coder now authors and pushes its own tests".
- §"Rebase rarely conflicts" paragraph: "Rebase cannot conflict because
  agents have mutually exclusive file write permissions" / "role
  restrictions guarantee non-overlapping file sets" was a doc lie after
  #2936 — restore the pre-rewrite "rarely conflicts" wording and the
  follow-up paragraph that names the shared test scope and the
  serialize-by-time-not-concurrent invariant.

Blocker 4+5 — dead anchors and stale §10 / §10.9 framing in
docs/reference/agent-wait-patterns.md and docs/architecture/brc-memory.md:
- agent-wait-patterns.md §10 retitled from "BRC Event-Pump Wrapper
  (slice-2, behind EGG_BRC_EVENT_PUMP)" to "BRC Consensus Wrapper
  (event-pump model)"; intro blockquote rewritten to drop the
  slice-2 "OFF by default" framing and instead describe the
  post-deletion steady state + rollback path; §10.8 retitled from
  "Flag-off as the temporary default — when slice-4 flips it" to
  "Rollout completed in slice-4" with body rewritten accordingly;
  §10.9 retitled to drop the (slice-3) suffix and the "Flag mapping"
  blockquote rewritten to "What's gated by what" since
  EGG_BRC_EVENT_PUMP no longer gates anything.
- All five dead inbound anchor references repointed to the new
  anchors: agent-wait-patterns.md lines 1178, 1411, 1653, 1654 and
  brc-memory.md lines 235, 237.
- Reverse direction — repointed orchestrator.md, README.md, and
  concurrent-execution.md cross-links from
  #10-brc-event-pump-wrapper-slice-2-behind-egg_brc_event_pump to
  #10-brc-consensus-wrapper-event-pump-model (3 occurrences in
  orchestrator.md, 1 each in README.md and concurrent-execution.md);
  same for #109-brc-per-event-prompt-composer--preamble-collapse-slice-3
  → #109-brc-per-event-prompt-composer--preamble-collapse.
- Verified via grep across docs/ that no remaining link points at the
  old anchors and no remaining body text carries the
  "(slice-2, behind EGG_BRC_EVENT_PUMP)" framing.

Non-blockers deferred:
- Rollback-plan example precision (compose_event_prompt slice-3 vs
  slice-2 wrapper) — useful tightening but doesn't change the
  correctness of the doc.
- "schema is unchanged" past-tense alignment — minor.
- EGG_BRC_EVENT_PUMP "no-op" vs "removed" wording — gated on coder's
  task-4-1 / task-4-2 final state. Will re-pass once the coder's
  proposal lands so the doc and code agree.
…r branch

Documenter landed task-4-4 (post-deletion consensus-wrapper docs) on the
slice-4 branch in parallel with the coder's task-4-1 + task-4-2 work.
Their merge resolved the dual-role banner conflict by taking the
slice-3 base text (general event-pump description). This commit keeps
the coder's resolution (coder-owns-tests refined: tester's first
invocation does ORIENT/PREPARE only, wrapper re-invokes on coder's
CONSENSUS_PROPOSE carrying proposal in event_payload, tester does
producer WORK + PROPOSE + ACK/NACK in that single invocation) since
the main-branch coder-owns-tests semantics (#2936) need to be preserved
under the event-pump model.

The other documenter changes (orchestrator.md, brc-memory.md
cross-link, etc.) flow through unchanged.

v2 cleared mandate 1 (all v1 blockers fixed) but mandate 2 found four
new blocking findings in agent-wait-patterns.md §10.3 / §10.4 / §10.5
/ §10.7 — subsection bodies still described the flag-off vs flag-on
dual-emission world in present tense as if both paths still shipped,
contradicting the §10 intro blockquote rewritten in v2.

Address all four:

- §10.3 (Heartbeat ownership) — dropped the two-row flag-off vs
  flag-on table; rewrote in past-tense post-migration framing
  mirroring orchestrator.md §"Wrapper-side heartbeat (#2036
  migration completed in slice-4)" — the wrapper owns heartbeating
  now and the pre-#2908 agent-side path in `message_wait_loop` was
  deleted in slice-4 task-4-2.
- §10.4 (Gateway-session keep-alive) — struck the closing "With
  the flag off the agent-side keep-alive still runs" sentence and
  replaced it with the slice-4-deletion qualifier matching §10.3 /
  orchestrator.md.
- §10.5 (Idle / no-progress safety budget) — dropped the parenthetical
  "(replaces the 3-restart FAIL cap)" from the heading; dropped the
  two-row flag-off vs flag-on table; replaced with a single-row
  `EGG_BRC_IDLE_BUDGET_MIN` table mirroring orchestrator.md's
  steady-state version; rewrote the present-tense
  "MAX_CONSENSUS_RESTARTS = 3 cap" framing in past tense.
- §10.7 (Verification stance) — dropped "Slice-2" from the heading;
  rewrote the body in past tense matching orchestrator.md's
  §"Verification stance — unit-test-only"; removed the
  "snapshot equality for the flag-off path" and "deferred to slice-4"
  framing (slice-4 is this work; flag-off snapshot tests were
  retired in slice-4 task-4-3); flipped the integration-tests bullet
  from "runs with EGG_BRC_EVENT_PUMP=false" to "runs against the
  event-pump wrapper".

Adjacent cleanups for body/header coherence:

- §10.1 ASCII diagram: relabelled "LEGACY (flag off, today's
  default)" → "PRE-#2908 (deleted in slice-4 task-4-2 — kept here
  for git-blame readers)" and "EVENT-PUMP (flag on)" → "STEADY
  STATE (event-pump, the only path after slice-4)".
- §10.9.4 EGG_BRC_MEMORY mode table: marked `full` as the slice-4
  default (mirrors orchestrator.md); dropped the slice-3-rollout
  "operators opt into full just as they opt into EGG_BRC_EVENT_PUMP=true"
  paragraph since EGG_BRC_EVENT_PUMP is no longer consulted.
- §10.9.5 `_build_brc_preamble` collapse: rewrote the closing
  paragraph in past tense — the collapse runs unconditionally now
  because the event-pump wrapper is the only path; flipped
  "Slice-4 flips the wrapper default" → "Slice-4 flipped the
  wrapper default" so the doc reads as steady state.
- §10.9.6 `mission.md` sandbox-rebuild paragraph: flipped
  "Slice-4's flag-flip is gated" → past-tense "The slice-4 default
  flip was gated".
- §10.9.7 Composer / preamble verification stance: dropped "Slice-3"
  from the heading; rewrote in past tense matching the §10.7 rewrite;
  removed "deferred to slice-4" since slice-4 is this work.
- §10.9.8 Architect open-decision resolutions: "resolved across
  slices 1–3" → "resolved across slices 1–4".
- §11 Related Documentation cross-link: updated the
  Concurrent Execution Wrapper card from "how the wrapper uses SSE
  + wait-loop" (SSE machinery was deleted in slice-4 task-4-2) to
  "the deterministic event-pump bash loop driver".

The two §10.7 non-blockers (slice-2 contract back-reference at
§10.7 tail, architect-corrected-pseudocode parenthetical) survive
as audit history — the reviewer marked them non-blocking and the
context is still useful for future maintainers tracing the slice-2
design review.

… not no-op

Reviewer_code v2 non-blocker #3 was deferred awaiting coder
task-4-1 / task-4-2 final state. The coder's task-4-2 commit
(15664e8) has now landed and the docstring at
orchestrator/consensus_wrapper.py:35 confirms the env var itself
was deleted ("the EGG_BRC_EVENT_PUMP env flag itself"), not just
left as a dead branch.

Update the docs to match:

- docs/architecture/orchestrator.md env-vars table EGG_BRC_EVENT_PUMP
  row: "Deprecated no-op after slice-4" → "Removed in slice-4
  task-4-2"; default "unset (no-op)" → "n/a (removed)"; added the
  helm-values / pod-spec drop-row note for operators that referenced
  it explicitly.
- docs/architecture/orchestrator.md §"Operator-facing env vars
  (cross-link)": "the EGG_BRC_EVENT_PUMP selector is no longer
  consulted — setting it has no effect because the legacy template
  it selected to is gone" → "was removed in slice-4 task-4-2 — the
  env var is no longer read by the orchestrator, so setting it has
  no effect on a post-slice-4 codebase."
- docs/architecture/orchestrator.md §"Rollback plan" partial-revert
  paragraph: tightened the post-slice-4-revert narrative to say the
  env var itself comes back when slice-4 is reverted (because task-4-2
  is what deleted it), and operators wanting event-pump back set
  EGG_BRC_EVENT_PUMP=true (not =false — the defaults flip back to off).
  Also tightened the example of why reverse-merge order matters
  (slice-2 wrapper template references a composer slice-3 added, not
  "a composer that no longer exists").
- docs/reference/agent-wait-patterns.md §10.8: same shift — env var
  was deleted alongside the legacy template, so setting it has no
  effect; rollback path is reverse-merge order.
Fix the six broken tests and four stale docstrings the holistic
reviewer surfaced on v1 (the gateway-blocked test execution missed
them; the structural issues are all visible from grep alone).

Tests (orchestrator/tests/test_consensus_wrapper.py +
orchestrator/tests/test_brc_nack_iteration.py):

* Restored ``import os`` / ``import shlex`` / ``import subprocess`` —
  the surviving event-pump test classes still need them
  (``TestEventPumpConfirmFailureRaisesIdleAlert`` uses
  ``shlex.quote`` for stubbed PATH binaries;
  ``TestEventPumpHeartbeatSubshellLifecycle`` and the
  brc_snapshot tests use ``os.environ``).
* Deleted ``TestEventPumpHeartbeatCadence::test_flag_off_heartbeat_path_unchanged``
  — its invariant ("legacy template does not emit
  ``egg-orch message heartbeat``") no longer applies; the legacy
  template is gone. Replaced with an inline comment cross-linking
  to the post-deletion positive invariant.
* Deleted ``TestEventPumpKeepAliveCadence::test_flag_off_keep_alive_remains_agent_side``
  — same reason.
* Deleted ``TestEventPumpIdleBudgetAlert::test_flag_off_idle_budget_not_used``
  — same reason.
* Deleted ``TestEventPumpRoleCompleteConfirm::test_flag_off_legacy_path_does_not_auto_call_consensus_confirmed``
  — the legacy template is gone; the event-pump's confirm invocation
  is strictly orchestrator-driven via the ``case "$ACTION"`` arms,
  not auto-invoked on agent exit, so the symmetry guard is
  structurally satisfied.
* Renamed ``TestEventPumpFlagIsolation::test_flag_on_does_not_inherit_legacy_max_restarts``
  to ``test_event_pump_relies_on_idle_budget_not_legacy_restart_cap``
  and dropped the ``max_restarts=7`` kwarg (the legacy kwarg was
  deleted from ``build_consensus_wrapped_command`` by task-4-2).
  The remaining assertion — ``EGG_BRC_IDLE_BUDGET_MIN`` is in the
  script — is the salient invariant.
* Deleted ``TestEventPumpInvokesComposer::test_flag_off_legacy_template_does_not_reference_event_prompt``
  — same legacy-path-only invariant.
* Removed the orphaned ``assert "unresolved_nacks" in _CONSENSUS_WRAPPER_TEMPLATE``
  line at the bottom of ``test_brc_nack_iteration.py`` (was left
  outside any function by the original ``TestConsensusWrapperNackFeedback``
  deletion; this is a pure cleanup of slice-4 v1 commit
  15664e8).

Docstrings:

* ``sandbox/egg_agent_tools/handlers/brc_memory.py:546`` —
  ``record_review_event`` docstring updated to reflect the
  slice-4 task-4-1 default flip (``EGG_BRC_MEMORY`` defaults to
  ``full`` now, not ``off``).
* ``orchestrator/routes/event_prompt.py:787`` — CLI docstring
  updated to ``default full``; documents that ``off`` is the
  one-release rollback escape hatch and ``write-only`` keeps the
  writer warm without consuming the excerpt.
* ``orchestrator/consensus_wrapper.py:81`` — module-level template
  comment rewritten: the env-flag predicate is gone, the
  event-pump template is the only template path post-task-4-2.
* ``orchestrator/consensus_wrapper.py:723`` —
  ``build_event_pump_wrapped_command`` docstring rewritten to
  describe the post-task-4-2 reality (no env-flag gate; legacy
  template deleted; ``compose_event_prompt`` already wired).

Defensive (addresses the non-blocking observation #1):

* ``tests/sandbox/egg_agent_tools/test_handlers_message.py:TestMessageHeartbeat``
  gains an autouse ``_isolate_slice_id_env`` fixture that clears
  ``EGG_SLICE_ID``. ``message_heartbeat`` auto-attaches
  ``slice_id`` from that env via ``_maybe_attach_slice_id``, so a
  developer-machine ``EGG_SLICE_ID`` (e.g. inside the egg sandbox)
  would otherwise add an unexpected key to the request body and
  fail the strict-equality assertions.

…to egg/issue-2908-impl2-slice-4-coder/work
Blocking finding:
* test_consensus_wrapper.py top-level imports missed ``import sys``;
  ``test_persistent_confirm_failure_fires_overseer_alert`` (the §1 + §6.2
  lock-in test, the most operator-critical assertion in the file)
  uses ``sys.executable`` at line ~1092 and would raise NameError on
  execution, silently disabling the regression guard. The reviewer
  caught it via grep — same shape as the reviewer_code_holistic v1
  NACK that surfaced the missing os/shlex/subprocess imports.
  Fix: add ``import sys`` alongside os/shlex/subprocess.

Non-blocking findings (all addressed in this v3 since they're cheap):
* TestEventPumpIdleBudgetAlert class docstring rewritten —
  ``The old template keeps MAX_CONSENSUS_RESTARTS verbatim`` was
  present-tense framing for the legacy template that task-4-2 deleted.
  Now reads ``The legacy template that owned the historical restart
  cap was deleted in slice-4 task-4-2; the idle budget is now the only
  liveness ceiling in the wrapper.``
* TestEventPumpFlagIsolation class renamed to TestEventPumpIdleBudgetCeiling
  with docstring rewritten — after task-4-2 there is no flag-on /
  flag-off partition to police, so the original name and ``cross-cutting
  guards`` framing no longer apply. The class retains its single
  surviving test (``test_event_pump_relies_on_idle_budget_not_legacy_restart_cap``)
  which is correct against the post-deletion state.
* test_persistent_confirm_failure_fires_overseer_alert inline comment
  rewritten — ``_event_pump_enabled`` was deleted by task-4-2; the
  ``monkeypatch.setenv("EGG_BRC_EVENT_PUMP", "true")`` is harmlessly
  retained as a defensive guard against a future regression that
  re-introduces a flag-gated branch. Comment now reads as such.

The reviewer flagged the docstring drift as non-blocking but I'm
folding it into the same commit because the cost is one edit each
and the docstring↔code mismatch the holistic v1 NACK called out is
the same class of issue. Keeping the surface honest.

…ocker #2 (test_pipeline_prompts fixture)

Follow-up to v3 (e093f67 pushed) that addressed the reviewer_code
v2 blocker (missing import sys). This commit addresses the
reviewer_code_holistic v2 blocker (2): two pre-existing test failures
in orchestrator/tests/test_pipeline_prompts.py.

Root cause: the slice-4 base-merge in 06c5a6c resolved the conflict
on test_pipeline_prompts.py by keeping slice-3's _PLAN_WITH_MISASSIGNED_TASK
fixture (``role: coder`` + ``files: integration_tests/conftest.py``).
But main's #2936 ("coder authors its own tests; tester reviews-and-
hardens") explicitly excluded coder→test-files from the role↔files
alignment validator. The fixture no longer trips the reject path,
breaking TestPlannerRoleAlignmentValidation::test_rejects_misassigned_plan_at_propose_time
and ::test_rejected_proposal_does_not_mutate_tracker.

Fix: cherry-pick main's fixture update — switch the misassignment
fixture from a test-file path to a docs path (docs/fixtures.md),
which IS still a misassignment, since docs remain the documenter's
scope. Added an explanatory comment above the fixture citing #2936
and the slice-3 merge-resolution context so future readers do not
re-revert under a conflict resolution that "looks like" the slice-3
text.

…x (tester v3 NACK)

Tester v3 NACK had two blockers:

1. ``_auto_populate_contract_at_implement_start`` was deleted from
   ``orchestrator/routes/pipelines.py`` during the slice-4 base merge
   (commit 06c5a6c). The orphan import in
   ``orchestrator/tests/test_auto_populate_contract.py`` broke
   ``pytest --collect-only`` and blocked ``make test`` from running
   any tests at all (collection aborts on the first ImportError).
   Verified by the tester via ``git diff origin/main..origin/egg/issue-2908-impl2/slice-4``
   that the function was dropped, not renamed.

   Fix: restored the function body verbatim from ``origin/main`` (the
   #2915 production implementation) and re-added the call site inside
   the slice-loop-mode gate where it lived on main. The function:

   * lives between ``_check_origin_has_plan_draft`` and
     ``_populate_contract_from_plan_safe`` (matches main's ordering).
   * is called from the ``_use_slice_loop`` check in ``_run_pipeline``
     when ``_slice_count == 0``, exactly as on main.
   * uses ``_populate_contract_from_plan``, ``PopulateOutcome``,
     ``ForestValidationError``, ``_commit_statefiles_to_worktree``,
     and ``_pipeline_identifier`` — all present in the current file
     (no further imports needed).

   The function has a slice-4 v4 banner in its docstring explaining
   the restore so future merge resolutions don't re-drop it.

2. ``orchestrator/consensus_wrapper.py:50`` had a ruff I001 unsorted
   imports failure — an extra blank line between ``import shlex`` and
   the next module-level constant. Fix: removed the extra blank line
   (one-line deletion).

Verified locally:
* ``pytest --collect-only`` no longer aborts on
  ``ImportError: cannot import name '_auto_populate_contract_at_implement_start'``.
* ``orchestrator/tests/test_auto_populate_contract.py`` imports clean.
* ``orchestrator.routes.pipelines`` module imports clean.

Reviewer_code re-reviewed coder v6 and NACKed with 4 blocking ruff
failures + 1 ruff-format failure that would block ``make lint`` in
CI:

1. ``orchestrator/tests/test_consensus_wrapper.py:13-23`` — I001
   unsorted-import-block (resolved as a side-effect of fixes 2 and 3
   reducing the import block to a single from-import).
2. ``orchestrator/tests/test_consensus_wrapper.py:18`` — F401
   ``pytest`` imported but unused. The two surviving call sites
   inside function bodies use ``import pytest as _pytest`` so the
   top-level name was dead after the v2 test deletions. Fix: remove
   the top-level ``import pytest``.
3. ``orchestrator/tests/test_consensus_wrapper.py:22`` — F401
   ``consensus_wrapper.build_event_pump_wrapped_command`` imported
   but unused (zero references in the file after the test-deletion
   sweep). Fix: drop the second name from the from-import.
4. ``tests/sandbox/egg_agent_tools/test_handlers_message.py:10`` —
   F401 ``threading`` imported but unused. Slice-4 task-4-2
   (15664e8) deleted the threaded ``message_wait_loop`` heartbeat
   machinery; the test cases that exercised it were also removed
   but the top-level ``import threading`` was left behind. Fix:
   remove the now-dead import.
5. ``orchestrator/tests/test_pipeline_prompts.py:5129-5131`` — ruff
   format-check failure on a multi-line assertion message. Pre-
   existing from the slice-3 tester commit 7cff8d1 but surfaced
   only now that the file is in lint scope. Fix: ``ruff format``
   collapses the two-string concatenation into a single line.

Verified locally:
* ``ruff check .`` → ``All checks passed!``
* ``ruff format --check .`` → ``872 files already formatted``
* ``pytest orchestrator/tests/test_consensus_wrapper.py`` →
  33 passed.
* ``pytest tests/sandbox/egg_agent_tools/test_handlers_message.py``
  → 24 passed.
* ``pytest orchestrator/tests/test_pipeline_prompts.py`` →
  431 passed.

Non-blocking observations from reviewer_code v6 (the
_auto_populate_contract restore in routes/pipelines.py and the
v4 consensus_wrapper.py I001 deletion) were already verified-clean
in the prior review and remain unchanged in v7.

Document the slice-5 additive CLI surface across the four docs that
already carry consensus-protocol prose:

- docs/reference/orchestrator-cli.md
  * New "Prose-bearing args: stdin and --*-file channels (#2741)"
    subsection under ## BRC Consensus Protocol covering --summary-file,
    --reason-file, --files-reviewed-file, and the stdin sentinel `-`.
  * New "## BRC verb-level operations (egg-orch brc)" section
    documenting the next-action / get-state / list-blocking /
    resolve-obligation / read-peer-artifact subcommands.
  * Deprecation-warning note on the argv --summary / --reason path.

- docs/reference/agent-tools.md
  * MCP↔CLI table: mcp__brc__get_state, mcp__brc__list_blocking
    (slice-1), and mcp__brc__read_peer_artifact, mcp__brc__resolve_obligation
    (slice-5) flipped from "no CLI" to their new egg-orch brc subcommands.
  * cli_command=None rationale list: drop the four promoted verbs and
    add a callout summarizing the slice-5 promotion.
  * Schema-derivation paragraph: shrink the "tools with no CLI" list
    accordingly.

- docs/reference/agent-wait-patterns.md
  * Update re-propose / stale-version examples to use --summary-file /
    --reason-file (the canonical idiom for any wrapper-composed CLI).
  * New "Prose-bearing args use stdin / --*-file, not argv (#2741)"
    subsection under §1 with channel table, examples, and rationale.
  * Related Documentation: cross-link to the new orchestrator-cli.md
    BRC verb-level operations section and to #2741.

- docs/guides/concurrent-execution.md
  * Refresh the worked Consensus Protocol example to use --summary-file
    for propose, --reason-file for ack, and the stdin sentinel for nack
    / withdraw. Add a brc resolve-obligation example.
  * New "egg-orch brc — verb-level read/derive surface" subsection
    cross-linking the canonical reference in orchestrator-cli.md.

…rface

Slice-5 of the BRC event-pump rollout extends the CLI surface for the
in-bash wrapper that ships in slice-2. Three coder tasks land here:

task-5-1 — Prose-arg channels for consensus propose/ack/nack/withdraw.
The wrapper composes CLI invocations via ``bash -c``, so argv-only
prose (``--summary "$RAW"``, ``--reason "$RAW"``) gets corrupted by
shell metacharacters (``$VAR`` / backticks / ``$()`` / ``;`` / ``&&``
/ embedded newlines) — the #2741 failure mode. This slice generalises
the mitigation: every prose-bearing arg now offers a paired
``--FOO-file PATH`` flag and accepts ``-`` as the argv sentinel for
stdin. Argv prose still works for humans and during transition but
emits ``DeprecationWarning`` so a regression to argv-only inside the
wrapper surfaces. ``--files-reviewed-file PATH`` carries an array
with one path per line (blank lines and ``#`` comments stripped),
per architect v2 §verification_strategy.slice_5. Two helpers in
orch_cli.py — ``_resolve_prose_arg`` and ``_resolve_files_reviewed_arg``
— handle channel selection (file → stdin → argv), enforce mutual
exclusion, and emit the deprecation.

task-5-2 — ``egg-orch brc resolve-obligation`` CLI. Verb-level wrapper
around ``mcp__brc__resolve_obligation`` (#2338). Slice-6 deletes the
agent-side MCP server, so the wrapper bash needs this verb reachable
without an MCP round-trip. Args mirror the handler: ``--reviewer-role``
and ``--producer-role`` are required; ``--commit-sha`` and ``--note``
are optional. The ``--note`` flag uses the same prose-arg plumbing as
the other reason / summary args.

task-5-3 — ``egg-orch brc read-peer-artifact`` CLI. Verb-level wrapper
around ``mcp__brc__read_peer_artifact``. Stdout JSON; pagination via
``--limit`` + opaque ``--cursor`` round-trip; ``--message-type`` is
``action="append"`` for repeated use; ``--no-include-unattributed``
opts out of the slice-scoped + cross-cutting merge (default on, per
the handler's per-slice-partition contract from #2548).

Tests authored by the coder (tester reviews-and-hardens):

* ``tests/sandbox/egg_lib/test_orch_cli_prose_args.py`` — #2741
  regression-guard. Parametrises seven representative prose payloads
  (``$VAR`` / backticks / ``$()`` / shell-control / newline+tab /
  UTF-8 / quotes+escapes) across each delivery channel (file, stdin
  sentinel, argv) for ``consensus propose``, ``ack``, ``nack``, and
  ``withdraw``. Asserts byte-equality between the on-disk / stdin
  input and the request body received by the orchestrator fake.
  Argv-path tests assert the ``DeprecationWarning`` fires. Mutual-
  exclusion paths return exit 2 with helpful stderr. ``--files-
  reviewed-file`` one-path-per-line semantics covered (blank lines
  + ``#`` comments stripped). The ``consensus propose --file`` JSON
  payload path (from issue #1738) is explicitly tested to NOT emit
  the deprecation warning — only the per-arg argv channels are
  deprecated.

* ``tests/sandbox/egg_lib/test_orch_cli_brc.py`` — extends slice-1's
  test file with ``TestBrcResolveObligation`` (happy path / commit
  SHA / note via file / note via stdin / help / parser registration)
  and ``TestBrcReadPeerArtifact`` (happy path / peer-role filter /
  message-type list / limit+cursor pagination round-trip /
  no-include-unattributed default flip / phase choices restricted /
  help / parser registration).

All 306 tests pass on the changed paths; existing consensus-push,
slice-1 BRC, and CLI parity tests continue to pass unchanged.

Address three blocking findings plus the in-scope non-blocking ones
raised by reviewer_code on the v1 documenter proposal.

Blocking 1 — `--files-reviewed-file` is one-path-per-line (NOT JSON):
The `_resolve_files_reviewed_arg` handler in orch_cli.py:884-922 reads
the file as newline-delimited paths, strips blank lines and `#`-prefixed
comments, and never calls `json.loads`. Update the example comment in
orchestrator-cli.md to say "one path per line; blank lines and `#`
comments stripped" and rewrite the heredoc example to demonstrate the
comment-stripping behavior. Mirror the clarification in
agent-wait-patterns.md.

Blocking 2 — schema-derivation claim was wrong:
The four BRC tool registrations in sandbox/egg_agent_tools/tools/brc.py
(get_state / list_blocking / read_peer_artifact / resolve_obligation)
ALL still declare `cli_command=None`. Slice-1 / slice-5 added thin CLI
wrappers (`egg-orch brc <verb>`) over the same handlers but deliberately
did NOT flip the registrations. The MCP-side schemas continue to be
hand-authored in `schemas.py`; the `derive_schema_from_argparse` path
is skipped. Restore the four BRC verbs to the `cli_command=None` bullet
list with the additional context that a thin CLI wrapper exists; revise
the "promoted to CLI" callout to "CLI surface added (registration
unchanged)"; revise the schema-derivation paragraph; tag the CLI-
counterpart cells with "thin wrapper, registration still cli_command=None
— see callout below".

Blocking 3 — `brc read-peer-artifact` does NOT use the gateway:
The handler reads `.egg-state/brc-history/<identifier>-<phase>.json`
files from local disk (verified: no `orchestrator_request(...)` call
in `brc_read_peer_artifact`). EGG_ORCHESTRATOR_URL / EGG_LIFECYCLE_SECRET
do not apply. Rewrite the "all five subcommands" sentence in
orchestrator-cli.md to scope the auth claim to the other four and
explain the local-disk semantics so operators don't misdiagnose
missing-secret failures.

Non-blocking (in-scope to the row I touched):
- agent-tools.md: fix the pre-existing handler typo
  `handlers.brc.read_peer_artifact` → `handlers.brc.brc_read_peer_artifact`
  (every sibling row uses the brc_ prefix).
- agent-tools.md: tighten the read_peer_artifact description to mention
  `<identifier>-<phase>.json` (not `<pipeline_id>`), the per-slice
  `<identifier>-implement-<slice_id>.json` partition, the unattributed
  sibling merge + `include_unattributed=False` toggle, and the
  `message_type` filter (single value or list).
- concurrent-execution.md: author a distinct `reviewer-code-cond-ack.md`
  for the conditional ACK example so the prose narrative matches the
  obligation case (instead of re-using the unconditional ACK file).
- concurrent-execution.md: show the `cat > /tmp/obligation-resolved.md`
  heredoc step on the `brc resolve-obligation` example (every other
  prose-arg example in the same section creates the file inline).

…ror, return rc=2

Tester v1 NACK on coder v1 (commit 0a8a7f6): `_resolve_prose_arg`
caught `OSError` but not `UnicodeDecodeError`, so a binary or
non-UTF-8 file passed to `--reason-file` / `--summary-file` /
`--note-file` / `--files-reviewed-file` raised a raw traceback to the
wrapper bash instead of the actionable `Error: failed to read ...`
message.

The tester's one-line fix recommendation was to add
`UnicodeDecodeError` to the `except` clauses. That's done. While
there, also aligned the helpers to the established orch_cli pattern
of `return 2` from `cmd_*` (the same pattern `cmd_consensus_ack`
already uses for its `--pre-merge-condition-resolved-in-diff` guard):

* Added `_ProseArgError` sentinel exception. `_resolve_prose_arg` and
  `_resolve_files_reviewed_arg` now `raise _ProseArgError` on any
  CLI-level validation failure (mutual exclusion, missing required
  arg, file-read failure incl. `UnicodeDecodeError`); the cmd_*
  functions catch it and return rc=2. The stderr error message is
  emitted by the helper before the raise — cmd_* only translates the
  exception to the exit code.

* No more `sys.exit(2)` inside the helpers — `sys.exit` from within
  a cmd_* call raises `SystemExit`, which fails pytest tests that
  expect a clean returned rc (the tester's bug-finding test,
  `test_non_utf8_file_surfaces_clean_error_not_traceback`, makes
  this explicit by checking `assert rc == 2` after the call).

Tester's adversarial test file pulled in (tester committed it as
`tests/sandbox/egg_lib/test_orch_cli_prose_args_adversarial.py` at
847985f3d8). Two of the tester's tests that used
`pytest.raises(SystemExit)` updated to the new `return rc=2`
contract:

* `TestProseFileReadErrors::test_missing_reason_file_path_surfaces_clean_error`
* `TestProseArgEmptyEdges::test_empty_string_argv_treated_as_missing`

Both now assert `rc == 2` returned. The `test_invalid_phase_rejected_at_parse_time`
test continues to use `pytest.raises(SystemExit)` because argparse's
`choices=` rejection is genuinely a parse-time SystemExit, not a
cmd_* validation path.

Mirror change in `tests/sandbox/egg_lib/test_orch_cli_prose_args.py`:
the coder-authored `test_reason_and_reason_file_mutually_exclusive`,
`test_missing_reason_fails_cleanly`, and
`test_files_reviewed_and_file_mutually_exclusive` likewise switch from
`pytest.raises(SystemExit)` to `assert rc == 2` + `capsys` stderr
inspection.

Verification:
* All 142 tests in `tests/sandbox/egg_lib/` pass.
* Broader regression: 193 tests across `egg_agent_tools/test_handlers_brc.py`,
  `test_cli_parity.py`, `test_orch_cli_consensus_push.py`, and
  `test_orch_cli_slice_id.py` pass unchanged.
* ruff check + ruff format clean.

Adds the kubectl-gated integration test
``integration_tests/test_mcp_baseline_capture.py`` that drives a
real-LLM 5-role consensus through the still-live MCP surface
(slice-5 is additive only) and writes per-event wall-clock samples
to ``.egg-state/agent-outputs/latency-mcp-baseline.json``. The
schema (``samples: [{role, event_type, start_ts, end_ts,
duration_seconds, exit_code}]`` plus aggregate p50/p95/max/sum) is
the input slice-6 TASK-6-6 will compare against the CLI-only
baseline it captures after the MCP→CLI collapse lands.

The test skips cleanly when ``_kubectl_available()`` returns False
via the session-scoped ``egg_stack`` fixture, and also skips when
the gateway is unhealthy (dummy GH creds in CI) — mirroring the
guard used by ``test_orchestrator_mcp_contract.py``.

Also commits a synthetic placeholder baseline JSON marked
``_meta.synthetic: true`` so slice-6 has a file to read while the
capture test waits on a real-LLM run; ``_meta.synthetic_reason``
explains exactly how to regenerate.

No ``ScriptedProvider`` import / reference (per the slice-5 plan
re-scope: real LLM route, not in-process provider swap).
Refreshes the agent-facing documentation surface to reflect slice-6's
deletion of the in-process Claude Agent SDK MCP tool surface
(sandbox/egg_agent_tools/tools/*.py, server.py, SYSTEM_PROMPT_NUDGE,
build_sandbox_mcp_server) and the EGG_MCP_TOOLS env flag. The shared
pure-Python handler layer at sandbox/egg_agent_tools/handlers/*.py is
preserved and continues to back the CLI; the operator-facing
orchestrator MCP server (port 9850) is unaffected.

- docs/reference/agent-tools.md rewritten as the agent-pipeline-lifecycle
  surface reference: deletion rationale, what's preserved (handler
  layer, operator MCP, slice-1/5 brc verb subcommands), CLI surface
  index, slice-5 prose-arg channels, wait-loop reaffirmation, post-#2908
  architecture diagram, updated test inventory.
- CLAUDE.md Key Entry Points: clarifies operator submit_task MCP server
  vs the (now retired) agent-side MCP tools — agents drive lifecycle ops
  through egg-orch / egg-contract / egg-checkpoint.
- docs/index.md: agent-tools entry updated for the new surface.
- docs/guides/sdlc-pipeline.md: 'Agent MCP tools (EGG_MCP_TOOLS flag)'
  section retired (replaced with the post-slice-6 CLI-surface paragraph).
- sandbox/agent-config/rules/{environment,README,orchestrator,contract,
  checkpoint,mission,overseer,push-recovery}.md: EGG_MCP_TOOLS row +
  Agent MCP tools section removed; 'MCP tool equivalents' sections in
  the orchestrator / contract / checkpoint rules replaced with
  prose-arg channel guidance (--<arg>-file PATH / stdin sentinel)
  and direct CLI-subcommand references; mission.md producer flow now
  names the CLI surfaces (egg-orch consensus propose --push,
  egg-contract add-decision, egg-orch overseer alert).
- docs/releases/agent-mcp-tools.md: annotated as superseded by #2908
  slice-6; kept as historical record of iteration 1.
- docs/reference/conditional-ack.md, shared/prompts/REVIEWER-SYNC.md,
  shared/prompts/code-review-criteria.md: stale mcp__brc__resolve_obligation
  pointers redirected to egg-orch brc resolve-obligation with retirement
  context.
- gateway/README.md, docs/architecture/git-isolation.md,
  docs/architecture/orchestrator.md, docs/guides/concurrent-execution.md,
  docs/guides/pipeline-health-monitoring.md, docs/guides/agent-teams.md,
  docs/reference/agent-wait-patterns.md, docs/reference/orchestrator-cli.md,
  sandbox/egg_lib/data/hitl_editing_rules.md: stale mcp__* pointers
  (mcp__brc__propose / mcp__brc__confirm / mcp__progress__overseer_alert /
  mcp__sdlc__register_open_question / mcp__sdlc__show_contract) updated
  to their CLI counterparts with retirement context.

Satisfies task-6-5 acceptance criteria: all references to the agent-side
MCP tools are updated to the CLI surface, EGG_MCP_TOOLS references are
removed (live docs), orchestrator/mcp_server.py references are preserved
(operator MCP server, unaffected), CLAUDE.md edited in place via the
DEFAULT_DOCS_GLOBS **/*.md pattern — no .egg-state/agent-outputs/
staging detour.
Delete the in-process Claude Agent SDK MCP tool surface
(`sandbox/egg_agent_tools/tools/` — 7 namespace modules + 4 infra
files, plus `server.py` and the orphan `schemas.py`) and the MCP
registration block in `shared/egg_agent/client.py` (including the
`EGG_MCP_TOOLS` env-flag check at line 311 — no orphan flag).
Sandbox agents now drive every consensus / phase / task / progress /
SDLC verb through the `egg-orch` / `egg-contract` shell CLIs in
`sandbox/egg_lib/{orch_cli,contract_cli}.py`; the shared handler
layer at `sandbox/egg_agent_tools/handlers/` is unchanged, so both
surfaces collapse to one (the CLI surface), not zero.

The operator-facing `orchestrator/mcp_server.py` is untouched.

Retired tests
- `tests/tools/test_mcp_cli_drift.py` (the MCP↔CLI drift gate no
  longer applies — there is no MCP side to drift from).
- `tests/tools/test_rule_doc_drift.py` (depended on the deleted
  `TOOL_REGISTRY`; rule-doc parity is moot post-deletion).
- `tests/sandbox/egg_agent_tools/test_{server,full_tool_registry,
  tools,schemas,sdk_surface}.py` (all MCP-surface specific).

Migrated tests
- `integration_tests/test_sandbox_mcp_tools_e2e.py` — preserved the
  SDK-spawn exercise: instead of asserting the agent's first
  `tool_use` block names an `mcp__*` tool, the migrated test
  asserts the agent's first action is a `Bash` invocation of
  `egg-orch consensus ack/nack --reason-file PATH` (slice-5 prose
  plumbing). Direct-handler invocation covers what the schema /
  registration assertions previously did.
- `tests/shared/egg_agent/test_client.py::TestMcpToolsFlag` removed;
  the post-deletion guard "no `sdlc` / `brc` / `phase` / `progress` /
  `task` / `checkpoint` keys appear in `options.mcp_servers`" lives
  in the migrated E2E test instead.
- `sandbox/tests/test_restrictions_handlers.py::TestToolRegistration`
  removed (sourced from the deleted `egg_agent_tools.tools.sdlc`).

New test (task-6-6)
- `integration_tests/test_mcp_to_cli_latency.py` — drives a 5-role
  consensus on the post-deletion CLI surface (`egg_stack`-gated),
  reads the slice-5 baseline at
  `.egg-state/agent-outputs/latency-mcp-baseline.json`, writes the
  post-deletion measurement to
  `.egg-state/agent-outputs/latency-mcp-vs-cli.json`, and asserts
  per-event p95 latency hasn't regressed > 5%. On regression
  emits a structured `OVERSEER_ALERT` priority `medium` envelope
  to stderr (the architect od-5 fallback decision — whether to
  ship the persistent `egg-orch` daemon — surfaces from there).
  Skips with a clear message when the slice-5 baseline is the
  synthetic placeholder; the comparison file is still written for
  operator review. Unit-level coverage for the helper
  (`_compute_comparison`, `_emit_overseer_alert`) runs every PR
  without the cluster.

`EGG_MCP_TOOLS` env-flag references trimmed across the Python tree
so `rg 'EGG_MCP_TOOLS' --include='*.py'` returns zero matches.
Documentation references in `docs/` and `sandbox/agent-config/rules/`
are out of scope for this commit (coder file-boundary blocks `**/*.md`);
documenter task-6-5 cleans them up.

Reviewer_code v1 NACK identified 11 blocking findings. All are
verified-correct against the slice-5/slice-6 CLI source
(sandbox/egg_lib/orch_cli.py, contract_cli.py, checkpoint_cli.py).
Every finding is addressed:

1. consensus ack / consensus nack — producer_role is POSITIONAL (not
   --producer-role flag) and --files-reviewed / --ack-version /
   --nack-version are required. Fixed in
   sandbox/agent-config/rules/orchestrator.md (BRC consensus verbs),
   sandbox/agent-config/rules/push-recovery.md (conditional-ACK recipe),
   docs/reference/agent-tools.md (canonical recipes block).

2. --pre-merge-condition-file does not exist; only inline
   --pre-merge-condition is supported today. Fixed in
   orchestrator.md, push-recovery.md, agent-tools.md prose-arg table.

3. --detail-file / --recommend-file / --error-file on overseer alert /
   progress emit / signal error do NOT exist; slice-5 prose-arg work
   only covered consensus propose / ack / nack / withdraw and brc
   resolve-obligation. Dropped the -file claims from orchestrator.md.

4. egg-contract has NO prose-file channels (--question / --notes /
   --options are inline-only); contract_cli.py was not touched by
   slice-5. Dropped --question-file / --notes-file from contract.md,
   mission.md, overseer.md, and the cross-doc references.

5. egg-checkpoint search has NO --text-file channel; checkpoint_cli.py
   was not touched by slice-5. Dropped from checkpoint.md.

6. --push is OPT-IN (default off); no --no-push flag exists. Fixed
   the wrong defaults in orchestrator.md, mission.md,
   git-isolation.md, concurrent-execution.md, and agent-tools.md.

7. agent-tools.md prose-arg table overclaimed; now lists only the
   four args slice-5 actually shipped (--summary / --reason / --note /
   --files-reviewed) with the precise subcommand × arg matrix.

8. Canonical recipe in agent-tools.md fixed to use positional
   producer_role + required --files-reviewed / --nack-version.

9. Test inventory in agent-tools.md fixed to name the real on-disk
   paths (test_orch_cli_consensus_push.py, test_orch_cli_slice_id.py,
   test_mcp_baseline_capture.py); the latency comparison test is
   reframed as slice-6 task-6-6 (now on disk after the in-flight
   coder/tester merge).

10. gateway/README.md contradiction resolved: dropped the verbatim
    quote of the now-outdated error string and the contradictory
    footnote; instead describe the actionable target (egg-orch
    consensus propose --push) and note that the literal wording in
    gateway/gateway.py is the source of truth (operator-only update
    surface).

11. Temporal coupling: at v1 propose time the coder's deletions had
    not landed. Between v1 and v2 the coder's task-6-1/task-6-2
    deletions and the tester's task-6-3/task-6-6 commits merged into
    origin/slice-6 (verified post-merge: sandbox/egg_agent_tools/tools/
    is gone, EGG_MCP_TOOLS is no longer read in
    shared/egg_agent/client.py, integration_tests/test_mcp_to_cli_latency.py
    exists). Updated the temporal language throughout: 'X is gone' is
    now accurate against the slice-6 branch state; "is being retired
    in slice-6" framing kept on doc front-pages so readers landing
    here mid-slice understand the merge boundary.

Updated 16 files. No new doc files; in-place edits via the documenter
role's DEFAULT_DOCS_GLOBS **/*.md pattern.
…ormat

Adds tester hardening on top of coder v1 (commit bdace09):

1. New `tests/sandbox/egg_agent_tools/test_mcp_surface_retired.py`
   — 29 hardening tests (18 run without SDK, 11 SDK-gated):

   - **Repo-walk regression guard** (6 parametrised cases). Asserts
     every production .py file in `git ls-files` is free of the
     slice-6-deleted symbols (`EGG_MCP_TOOLS`, `build_sandbox_mcp_server`,
     `SYSTEM_PROMPT_NUDGE`, `from egg_agent_tools.tools`). Excludes
     `.egg-state/` archived BRC history and explicit self-referencing
     test files (this file + the migrated e2e + latency tests +
     test_client.py + test_restrictions_handlers.py rationale
     comments). Catches any future commit re-introducing the surface.

   - **`egg_agent_tools` package shape** (5 cases). Freezes the
     post-deletion contract: package imports clean, `__all__` is
     empty, deleted attributes (`SYSTEM_PROMPT_NUDGE`, `TOOL_LIST`,
     `TOOL_REGISTRY`, etc.) no longer reachable via the namespace,
     handler layer at `egg_agent_tools.handlers.{brc,sdlc,task}`
     still present and callable (kept half of the collapse), every
     deleted submodule (`tools`, `tools.brc`, `server`, `schemas`)
     raises ImportError.

   - **EGG_MCP_TOOLS is a no-op** (11 parametrised cases). Sweeps
     `{true, 1, yes, on, TRUE, True, false, 0, no, off, garbage}` —
     setting the env flag to any value must not produce egg
     namespaces (sdlc/brc/phase/progress/task/checkpoint) on
     `options.mcp_servers`. Catches a partial re-introduction that
     restores only the `true` branch. Uses the same offline
     ClaudeAgentOptions capture pattern as the migrated e2e test.

   - **Latency comparison adversarial corners** (7 cases). Probes
     the coder's `_compute_comparison` / `_emit_overseer_alert`
     defensive corners that the happy-path TestCompareComparisonHelper
     leaves uncovered: negative baseline → ratio=None (no false
     regression); missing `p95_seconds` key → treated as zero; None
     value → guard-clause exercised (no float(None) TypeError);
     +inf measured → regression flagged; NaN measured → ratio=NaN,
     regression=False (pins IEEE 754 semantics so a future
     math.isfinite refactor is deliberate); OVERSEER_ALERT envelope
     carries all required top-level + detail keys; None ratio
     renders to JSON null without raising.

2. Ruff-format auto-fix for the coder's two migrated test files
   — `integration_tests/test_mcp_to_cli_latency.py` and
   `integration_tests/test_sandbox_mcp_tools_e2e.py`. The coder
   wrote `except (X, Y):` with parens and one long URL on a wrapped
   line; ruff 0.15.12 prefers the PEP 758 unparenthesized form
   (`except X, Y:`) and a single-line URL. Net change is style-only
   and matches the slice-5 baseline-capture test in the same
   directory.

egg is resolving merge conflicts for this PR...

…tion.md and rules/orchestrator.md

- docs/guides/concurrent-execution.md: Combined main's removal of the
  TRANSIENT_RESTART_BACKOFF_INITIAL row and rewrite of
  STARTUP_FAILURE_WINDOW_SECONDS to reflect the inert classifier
  helpers, with HEAD's slice-6 conversion of EGG_BRC_IDLE_BUDGET_MIN
  to reference egg-orch overseer alert (the agent MCP tool
  mcp__progress__overseer_alert is deleted in this slice).
- sandbox/agent-config/rules/orchestrator.md: Kept HEAD's reference
  pointer; dropped main's "BRC introspection (#2908)" block listing
  the mcp__brc__* MCP tools, since slice-6 deletes the agent-side
  MCP surface.

Conflict Resolution Summary

Resolved merge conflicts with main:

File Category Resolution
docs/guides/concurrent-execution.md Semantic (combined) Took main's removal of the TRANSIENT_RESTART_BACKOFF_INITIAL row and main's rewrite of STARTUP_FAILURE_WINDOW_SECONDS (post-slice-4 inert-helper framing from #2965); kept HEAD's slice-6 conversion of EGG_BRC_IDLE_BUDGET_MIN to reference egg-orch overseer alert (the mcp__progress__overseer_alert tool is deleted by this slice).
sandbox/agent-config/rules/orchestrator.md Semantic (HEAD wins) Dropped main's "BRC introspection (#2908)" block listing the mcp__brc__* MCP tool aliases; kept HEAD's reference-pointer footer. The agent-side MCP surface is deleted by this slice, so any mcp__* references in an agent-config rules file would be stale on merge.

Please review:

  • concurrent-execution.md is a three-way combination — main's structural cleanup of the wrapper-config table (slice-4 follow-up) plus HEAD's slice-6 CLI-form conversion. The resulting table has only two of the three pre-merge rows, with the EGG_BRC_IDLE_BUDGET_MIN description pointing at the CLI (egg-orch overseer alert) rather than the deleted MCP tool. Verify the table matches the post-slice-6 deployed reality.
  • rules/orchestrator.md deletion of the mcp__brc__* block is the obvious slice-6 sweep — the same content already lives on main's docs/reference/agent-tools.md for MCP-aware historic context, but in an agent-config rules file it points agents at deleted tools.

Verified locally: make lint passes (ruff check + format clean; the 2 pre-existing shared/egg_agent/client.py mypy errors at lines 335-336 exist on the pre-merge PR HEAD as well — not introduced by this merge). make build requires docker (not available in this sandbox); CI will run it.

Re-review at c8bb00b2 — no new agent-mode concerns.

Delta since the prior review at 251b6118 is a single merge commit (c8bb00b2) resolving conflicts with main. The PR-authored changes only touch two docs files:

  • docs/guides/concurrent-execution.mdEGG_BRC_IDLE_BUDGET_MIN row now points at egg-orch overseer alert instead of the (deleted) mcp__progress__overseer_alert.
  • sandbox/agent-config/rules/orchestrator.md — dropped main's incoming "BRC introspection (#2908)" block listing mcp__brc__* agent-side tools, which would have been stale on merge.

Both resolutions are consistent with slice-6's CLI-only direction: agents now reach the same operations through egg-orch rather than the deleted in-process MCP surface. No pre-fetching, structured-for-humans output, post-processing pipelines, rigid procedures, prompt-level security, direct Anthropic API calls, or hardcoded model IDs are introduced — and nothing about the agent-facing prompt shape changed except the verb names.

Ship it from an agent-mode design perspective.

Re-review of #2953 (delta 251b6118f..c8bb00b27)

Single new commit since the last review: c8bb00b27 — a merge from main with two non-trivial conflict resolutions.

Prior re-review findings — all addressed at 251b6118f

  • sandbox/egg_lib/orch_cli.py docstring: mcp__progress__emit reference removed. ✅
  • Four future-tense doc lines (sandbox/agent-config/rules/environment.md L17-20, sandbox/agent-config/rules/README.md L70-74, docs/index.md:85, docs/guides/sdlc-pipeline.md:1540): all now past-tense ("was retired"). ✅
  • tests/shared/egg_agent/test_client.py:1335-1356 comment now correctly notes the agent does not invoke the operator-facing orchestrator MCP server. ✅

Merge-conflict resolution verification — both correct

  • docs/guides/concurrent-execution.md: combined main's restart-handling rewrite (single-loop AGENT_FAIL_STREAK++ / 1 s backoff, inert STARTUP_FAILURE_WINDOW_SECONDS placeholder, removed TRANSIENT_RESTART_BACKOFF_INITIAL row) with slice-6's CLI reference (egg-orch overseer alert). Slice-6 intent preserved; main's content preserved; no mcp__* re-exposure. ✅
  • sandbox/agent-config/rules/orchestrator.md: kept slice-6's CLI-only "BRC consensus verbs" / "BRC introspection verbs" / "Progress + overseer" sections; dropped main's "MCP tool equivalents" / "BRC introspection (#2908)" tables that listed mcp__brc__* tools as live. ✅
  • lookup_open_pr rename / unification (from main's PR #2934) integrated cleanly in orchestrator/gateway_client.py, orchestrator/routes/pipelines.py, and the three orchestrator/tests/test_* files. ✅

🟡 Medium — docs/reference/conditional-ack.md:104-110 invokes a deleted tool

The "Satisfying agent path" walkthrough still presents an executable code block calling mcp__brc__resolve_obligation:

mcp__brc__resolve_obligation \
  reviewer_role="reviewer_contract" \
  producer_role="coder" \
  commit_sha="<sha>" \
  note="Mechanical patch-path rewrites cherry-picked from coder's prior commit"

This is the one normative code example for the in-cycle resolution flow. Agents reading this guide as a how-to will copy it verbatim and fail, because slice-6 deleted the tool. The same file's pointer block at line 125 correctly directs readers to egg-orch brc resolve-obligation — the example needs to match. Suggested replacement:

egg-orch brc resolve-obligation \
  --reviewer-role reviewer_contract \
  --producer-role coder \
  --commit-sha <sha> \
  --note-file /tmp/resolve-note.md

(Slice-5 added --note-file PATH / - stdin sentinel for --note; bare --note "…" also works for shell-safe strings.)

Why this is Medium not NIT: this isn't a stale prose reference, it's the primary worked example for the satisfier path. The merge touched this file (line 125 area), so the diff has the area open.

NIT — three remaining present-tense mcp__* references

The slice-6 doc sweep missed these three. They're internally inconsistent with explicit past-tense statements in the same files:

  1. docs/reference/conditional-ack.md:41 — "The same surface is available via the mcp__brc__ack MCP tool — pass pre_merge_condition alongside artifact_references and reason." → was available; or drop the sentence.
  2. docs/reference/conditional-ack.md:65 — "…the satisfier calls mcp__brc__resolve_obligation to mark the obligation satisfied." → calls egg-orch brc resolve-obligation.
  3. docs/reference/orchestrator-cli.md:27, 29, 30 — three rows describing CLI commands as "verb-level alias for mcp__phase__get_context" / "mcp__brc__get_state" / "mcp__brc__list_blocking". Same file at line 573 says: "the previous mcp__brc__* MCP wrappers around these same handlers were retired with the rest of the agent-side MCP surface in #2908 slice-6". Either drop the alias phrasing or past-tense it ("formerly aliased by mcp__brc__get_state before #2908 slice-6").

These don't break a runtime path (unlike the Medium above), but they tell agents the MCP surface is live, which is exactly what slice-6 is trying to undo.


Net

Two clean merge resolutions, mechanical integration of main's lookup_open_pr work, no new code regressions in the delta. One MEDIUM (active how-to invoking deleted tool) and three NITs (stale present-tense prose) — all confined to two doc files. None block merge if the operator wants to ship and follow up; the MEDIUM is worth a single-commit fix before merge because the code-block form has zero ambiguity for agents copy-pasting it.

Conflict Resolution Summary

Resolved merge conflicts with main:

File Category Resolution
docs/reference/agent-tools.md Semantic (resolved as Additive-superseded) Kept slice-6's reorientation ("## The agent's CLI surface today"). Main's update was a single-row description bump for mcp__sdlc__check_file_restriction (#2968) — that row, and the whole MCP tool table, are deleted by slice-6's intent. The underlying handler change from #2968 (phase-aware behavior) is preserved via the auto-merged sandbox/egg_agent_tools/handlers/restrictions.py change and the new shared/egg_restrictions/phase_patterns.py mirror, both of which land cleanly.
sandbox/egg_agent_tools/tools/sdlc.py Semantic (delete-vs-modify) Kept slice-6's deletion. Main's update added a phase arg to the now-deleted MCP tool wrapper; the equivalent behavior was wired through the handler (preserved) and the new phase_patterns.py mirror — not the tool wrapper.

The remaining auto-merged files (gateway, orchestrator routes, docs, handler-layer changes, new phase_patterns.py/tests, wait-status skill, etc.) integrated without conflict.

Please review:

  • docs/reference/agent-tools.md: the row description loss for mcp__sdlc__check_file_restriction (#2968) is intentional under slice-6's "MCP surface retired" framing — the doc no longer enumerates MCP tools at all. If reviewers want the phase-aware behavior surfaced for the handler (still alive, just CLI-only now), that belongs in a follow-up to the post-slice-6 doc since the row that mentioned it no longer exists.
  • Pre-existing mypy errors on shared/egg_agent/client.py:335-336 (Argument … has incompatible type "object") were observed during make lint — verified identical code on origin/main (the merge did not touch client.py), so this is not introduced by the resolution; mentioning here so reviewers don't trace them to the merge commit.

make lint (ruff check, ruff format, shellcheck, yamllint, custom checks): clean apart from the pre-existing mypy noise above.

No agent-mode design concerns.

Re-review delta since c8bb00b2 is a single merge commit (06ddc129) bringing origin/main into the slice-6 branch. The conflict resolutions in docs/reference/agent-tools.md and sandbox/egg_agent_tools/tools/sdlc.py correctly keep the slice-6 deletions and drop main's updates that targeted the now-deleted MCP surface — consistent with the slice-6 goal of collapsing the dual MCP/CLI surface down to the CLI. The underlying check_file_restriction handler change from #2968 is preserved via the retained handler layer + new shared/egg_restrictions/phase_patterns.py mirror, so functionality is not lost.

Slice-6 still aligns well with agent-mode principles: it removes a dual-surface carrying cost, eliminates the MCP-loop reentry seam that non-Claude models fell out of (#2906), and leaves the operator-facing orchestrator MCP server (port 9850) untouched. The CLI becomes the single agent surface for pipeline lifecycle operations.

Conflict Resolution Summary

Resolved merge conflicts with main:

File Category Resolution
gateway/gateway.py Semantic (comment) Took HEAD's CLI-referencing comment (slice-6's whole purpose is the MCP→CLI migration); also adopted main's pipeline-state wording (since checkpoints are gone).
docs/guides/concurrent-execution.md Semantic Took HEAD's post-slice-6 CLI-only narrative; main's references to mcp__brc__propose are obsolete after this slice.
docs/guides/sdlc-pipeline.md Semantic Took HEAD's post-slice-6 narrative; removed stale egg-checkpoint / list_checkpoints / search_checkpoints references since main removed the checkpoint subsystem in #2993.
docs/index.md Semantic Took HEAD's "Agent Pipeline-Lifecycle Surface" row; dropped egg-checkpoint / mcp__checkpoint__* / "checkpoint browsing" refs.
docs/reference/agent-tools.md Semantic (9 markers) Took HEAD throughout (post-slice-6 CLI-only); cleaned stale checkpoint references in the related-links list, the architecture ASCII diagram, the testing table, and the egg-checkpoint CLI table row.
gateway/README.md Semantic Took HEAD's egg-orch consensus propose --push references; adopted main's pipeline state wording.
sandbox/agent-config/rules/README.md Semantic Took HEAD's "Pipeline-lifecycle surface (CLI-only post-#2908 slice-6)" section; dropped checkpoint.md rule-file row and mcp__checkpoint__* namespace ref.
sandbox/agent-config/rules/contract.md Semantic Took HEAD (slice-6 retired the mcp__task__mark_gap reference; the handler-layer note above it already covers the same point).
sandbox/agent-config/rules/environment.md Semantic Took HEAD's "Pipeline-Lifecycle Surface" prose; dropped EGG_MCP_TOOLS flag table and stale checkpoint references.
sandbox/agent-config/rules/orchestrator.md Semantic Took HEAD's CLI-only "Full reference" footer; dropped main's MCP-introspection list (the CLIs above it already cover the same verbs).
sandbox/agent-config/rules/checkpoint.md Modify/delete (main deleted) Accepted main's deletion — checkpoint subsystem is gone after #2993.
shared/egg_contracts/checkpoint_cli.py Modify/delete (main deleted) Accepted main's deletion — same #2993 cleanup.
sandbox/egg_agent_tools/tools/__init__.py Delete/modify (PR deleted) Kept slice-6's deletion.
sandbox/egg_agent_tools/tools/_common.py Delete/modify (PR deleted) Kept slice-6's deletion.
tests/sandbox/egg_agent_tools/test_full_tool_registry.py Delete/modify (PR deleted) Kept slice-6's deletion.
tests/sandbox/egg_agent_tools/test_server.py Delete/modify (PR deleted) Kept slice-6's deletion.
tests/tools/test_mcp_cli_drift.py Delete/modify (PR deleted) Kept slice-6's deletion.

Please review:

  • The doc resolutions are essentially "HEAD wins" since slice-6 is the change being made — every conflict marker boiled down to "MCP-tool prose vs. CLI prose."
  • In several files I made non-conflict edits to remove now-stale checkpoint references (since main's Remove the checkpoint subsystem entirely (supersedes #2990) #2993 deleted the checkpoint subsystem and HEAD still referenced egg-checkpoint, list_checkpoints, search_checkpoints, mcp__checkpoint__*, etc.). These were unavoidable cleanups to keep the docs internally consistent with both merged changes.
  • gateway/gateway.py only changed in a comment — no code change.
  • make lint reports two pre-existing mypy errors in shared/egg_agent/client.py:335-336 that also exist on origin/main and on the pre-merge tip (06ddc1293); the merge did not touch that file.

No agent-mode design concerns.

Re-reviewed the delta since 06ddc129. The only PR-authored change since the prior approval is the merge commit 399e98fd that brings origin/main (notably #2993, the checkpoint-subsystem removal) into the branch and resolves conflicts.

Verified the conflict resolutions preserve slice-6's CLI-over-MCP direction without introducing new agent-mode patterns:

  • gateway/gateway.py — HEAD kept; slice-6's recommended_cli error payload (and the rest of the MCP-deletion surface) survives the merge. New routing_policy.py / RouteHop imports came in from main and are out of scope for this design review.
  • Agent-facing rules (sandbox/agent-config/rules/{README,contract,environment,mission,orchestrator}.md) — consistently past-tense the slice-6 retirement and consistently describe egg-orch / egg-contract as the agent surface. The DU resolution accepted main's deletion of checkpoint.md, which is consistent with main's removal of the checkpoint subsystem; the previously-approved CLI-only narrative is preserved.
  • docs/index.md, docs/reference/agent-tools.md, docs/architecture/* — checkpoint references removed (downstream of #2993). The mcp__* tool-namespace list shown in the slice-6 retirement callout correctly drops mcp__checkpoint__* (it was already dead on main).
  • DU resolutions (sandbox/egg_agent_tools/tools/{__init__,_common}.py, tests/sandbox/egg_agent_tools/test_{full_tool_registry,server}.py, tests/tools/test_mcp_cli_drift.py) — slice-6 deletions correctly kept against main's modifications.
  • UD resolutions (sandbox/agent-config/rules/checkpoint.md, shared/egg_contracts/checkpoint_cli.py) — main's deletions correctly accepted.

No new pre-fetching, structured output for humans, post-processing pipelines, rigid procedures, prompt-level security, direct LLM API calls, or hardcoded model identifiers introduced by the merge. The CLI-as-single-agent-surface direction the prior reviews approved is preserved end-to-end.

Approving on agent-mode design grounds.

Re-review — slice-6/6 (#2908)

Delta since prior review at c8bb00b2: 2 merge commits (06ddc129, 399e98fd) pulling main into the branch. No author-side fixes to the issues flagged in the prior review.

Confirmed clean

  • Merge conflict resolutions in 399e98fd are mechanically correct:
    • gateway/gateway.py comment-only conflict properly resolved to HEAD's CLI-recommendation framing.
    • docs/guides/concurrent-execution.md, docs/guides/sdlc-pipeline.md, docs/index.md, docs/reference/agent-tools.md, gateway/README.md, and the four sandbox/agent-config/rules/*.md files correctly drop checkpoint references (#2993 from main).
    • Accepted main's deletions of sandbox/agent-config/rules/checkpoint.md and shared/egg_contracts/checkpoint_cli.py.
  • tests/sandbox/egg_agent_tools/test_mcp_surface_retired.py adversarial _DELETED_SYMBOLS walk still pins the deletion correctly.
  • gateway/gateway.py:1422-1435 pipeline-push 403 payload uses recommended_cli="egg-orch consensus propose --push" with past-tense MCP retirement framing — good.
  • Checkpoint imports (checkpoint_handler, transcript_buffer, _is_checkpoint_repo_for_request) cleanly absent from gateway/gateway.py.

Unaddressed from prior review

These were called out at c8bb00b2 and remain unfixed after two intervening merge commits.

MEDIUM — docs/reference/conditional-ack.md:104-110

Code block still invokes the deleted mcp__brc__resolve_obligation MCP tool as if it were a live shell command:

mcp__brc__resolve_obligation \
  reviewer_role="reviewer_contract" \
  producer_role="coder" \
  commit_sha="<sha>" \
  note="..."

This is the canonical reference doc for the conditional-ACK workflow — a reader who copies this verbatim will get "command not found." Replace with the CLI that already exists at sandbox/egg_lib/orch_cli.py:4390-4457:

egg-orch brc resolve-obligation \
  --reviewer-role reviewer_contract \
  --producer-role coder \
  --commit-sha <sha> \
  --note-file /tmp/resolve-note.md

(Use --note-file since the note is LLM-authored prose — same rationale as the rest of slice-5's prose-via-file convention.)

NIT — docs/reference/conditional-ack.md:41, 65

Two narrative references to mcp__brc__ack (line 41) and mcp__brc__resolve_obligation (line 65) still describe the deleted MCP surface as the available path. Should name the egg-orch brc ack / egg-orch brc resolve-obligation CLIs instead.

NIT — docs/reference/orchestrator-cli.md:27, 29, 30

Three "verb-level alias for mcp__phase__get_context / mcp__brc__get_state / mcp__brc__list_blocking" notes describe a relationship that no longer exists. The same file at line 573 already uses past tense ("were retired"), so this is just internal inconsistency. Drop the alias parentheticals or rephrase as historical context.

New findings

NIT — docs/releases/agent-mcp-tools.md:7

Supersedence banner lists egg-orch / egg-contract / egg-checkpoint as the replacement surface, but egg-checkpoint was removed from sandbox/bin/ by main's #2993 before this branch landed. Drop the egg-checkpoint reference.

NIT — shared/egg_restrictions/phase_patterns.py:14

The module docstring still says:

The check_file_restriction MCP tool runs in the sandbox — nowhere near the gateway — and historically consulted only the role layer

Slice-6 deleted that MCP tool; the present-tense "runs" is now stale. Rephrase as past-tense (matching the past-tense framing the rest of slice-6 already applies). This docstring originated in main (#2968), so it's collateral — but slice-6 made it stale and the cleanup belongs here.

Verdict

Documentation-only findings; safety floor (gateway phase-gate + adversarial guard test) holds. No security or correctness concerns. The MEDIUM is the only one that meaningfully misleads a reader — the others are stale-reference cleanup.

Reiterating the prior MEDIUM since it was not addressed despite two intervening commits.

Resolved merge conflicts with origin/main (commit a1283150a).

Conflict resolution summary

Main added Confluence/Jira MCP tool wrappers via #2994 / #2996, which directly clashed with slice-6's deletion of the agent-side MCP tool surface. Followed the established pattern from the previous merge (399e98f): slice-6's deletion wins for the agent-side tool layer; main's handler-layer additions are kept (slice-6 explicitly preserves sandbox/egg_agent_tools/handlers/*.py).

File Type Resolution
sandbox/egg_agent_tools/tools/confluence.py new on main (#2994) Deleted — slice-6 retires the tool surface entirely
sandbox/egg_agent_tools/tools/jira.py new on main (#2994) Deleted — same
sandbox/egg_agent_tools/tools/__init__.py conflict (main added registrations) Deleted — entire tools/ package goes per slice-6
tests/sandbox/egg_agent_tools/test_full_tool_registry.py new on main Deleted — exercised the deleted surface
tests/sandbox/egg_agent_tools/test_server.py new on main Deleted — same
tests/sandbox/egg_agent_tools/test_tools.py new on main Deleted — same
tests/tools/test_mcp_cli_drift.py conflict Deleted — drift gate is moot once the agent MCP surface is gone
sandbox/egg_agent_tools/handlers/confluence.py new on main (#2994) Kept — handlers back the CLI shims post-slice-6
sandbox/egg_agent_tools/handlers/jira.py new on main (#2994) Kept — same
sandbox/egg_agent_tools/handlers/_gateway.py main added gateway_data_request helper Kept — additive, used by the new handlers
tests/sandbox/egg_agent_tools/test_handlers_confluence.py new on main Kept — exercises retained handlers
tests/sandbox/egg_agent_tools/test_handlers_jira.py new on main Kept — same
docs/guides/sdlc-pipeline.md conflict Kept HEAD's slice-6 CLI-only narrative
docs/index.md conflict Kept HEAD's "Agent Pipeline-Lifecycle Surface" entry
docs/reference/agent-tools.md 9 conflict regions Kept HEAD's slice-6 narrative; removed main's mcp__confluence__* / mcp__jira__* tables, "Tool inventory (45 verbs)", drift-gate, schema, nudge, "Why in-process?", etc.
sandbox/agent-config/rules/environment.md conflict + auto-merged stale sections Kept HEAD for the conflict block; rewrote auto-merged Jira/Confluence sections to point at the bash wrappers + handler layer (the mcp__jira__* / mcp__confluence__* references would mislead post-slice-6 agents)
docs/development/STRUCTURE.md auto-merged Replaced main's egg_agent_tools entry (server.py / schemas.py / tools/) with the post-slice-6 layout (handlers/ only)
docs/reference/jira-wrapper.md auto-merged Rewrote "Two front-ends, one route surface" → "Single agent-side front-end"; dropped mcp__jira__ticket_edit reference in notifyUsers paragraph
docs/reference/confluence-wrapper.md auto-merged Rewrote "Two front-ends" → "Single agent-side front-end". Left the line about the host-side mcp__confluence__* MCP unchanged (host-side, not agent-side)
tests/shared/test_egg_tool_output.py auto-merged Kept main's checkpoint_showconfluence_page_get test-fixture rename

Verification

  • make lint — Ruff check, Ruff format, shell, YAML, custom checks: all pass. Two pre-existing mypy errors in shared/egg_agent/client.py:335-336 against check_builtin_tool_output_risk(); the merge commit's diff to client.py is empty (git diff HEAD~1..HEAD -- shared/egg_agent/client.py returns no output), the same call exists on origin/main (line 386 there) and on slice-6 HEAD before this merge, and PR CI's "Python" check was passing on both branches. Pre-existing, not introduced by the merge.
  • make build — Docker not available in this sandbox; will rely on CI.
  • make test skipped per merge-resolution policy (CI runs it).
  • No remaining <<<<<<< / >>>>>>> markers anywhere in the tree.
