Risk: the contract task targets agent-tools.md and agent-wait-patterns.md but the densest existing coverage of consensus CLI flags lives in orchestrator-cli.md and concurrent-execution.md; landing updates only in the two contract-named files would create cross-doc skew. I updated all four to keep them consistent, per the contract's \"or equivalent \u2014 locate via Grep docs/\" guidance. Risk: the coder has not yet pushed slice-5 task-5-1..-5-3 work to origin, so the new CLI flags (--summary-file, --reason-file, --files-reviewed-file, --note-file) and brc subcommands (resolve-obligation, read-peer-artifact) are documented from the contract spec rather than from the implementation diff; reviewer should verify the documented surface matches the coder's eventual

reviewer_security for coder", + "body": "\nSecurity-lens ACK on coder v1 (commit 0a8a7f6a9, slice-5 tasks 5-1 / 5-2 / 5-3).\n\n### Scope reviewed\nRead the full diff against the slice-4 tip (518558c9f). Changes are confined to:\n- `sandbox/egg_lib/orch_cli.py` \u2014 adds `_resolve_prose_arg` / `_resolve_files_reviewed_arg` helpers, plumbs `--summary-file` / `--reason-file` / `--files-reviewed-file` / `--note-file` and stdin sentinel `-` into `consensus propose / ack / nack / withdraw`, registers `brc resolve-obligation` and `brc read-peer-artifact` subparsers + cmd handlers.\n- Two new test files (parametrised prose round-trip and brc-subcommand coverage). No production-code changes outside `orch_cli.py`.\n\n### Lens-by-lens findings \u2014 none blocking\n\n1. **Cross-file allowlist mismatch (\u00a71)** \u2014 clean. `_VALID_BRC_HISTORY_PHASES` is an intentional mirror of `_VALID_PHASES` in `sandbox/egg_agent_tools/handlers/brc.py`; the handler remains the source of truth (verified via Read of the handler) and the CLI's `choices=` is a usability check. Drift would only narrow the CLI surface, not widen access.\n\n2. **Handler-vs-validator path mismatch (\u00a72)** \u2014 clean. `cmd_brc_resolve_obligation` and `cmd_brc_read_peer_artifact` invoke the same `_handlers.brc_resolve_obligation` / `_handlers.brc_read_peer_artifact` functions the MCP server calls. No bypass route \u2014 every authorization gate (producer-cannot-self-resolve in resolve-obligation, the risk_analyst R2 cross-pipeline-read hardening that ignores caller-supplied `pipeline_id` in read-peer-artifact) is enforced server-side and unchanged. The docstring on `cmd_brc_read_peer_artifact` explicitly calls out this server-side identifier resolution.\n\n3. **Information disclosure / authz bypass (\u00a73)** \u2014 clean. No new public endpoints, no widened trust boundary. `cmd_consensus_nack`'s stdout `print(f\"NACK sent by {role} for {args.producer_role}: {reason_text}\")` echoes the resolved reason locally to the invoking agent; same audience as the old `args.reason` line \u2014 no new audience.\n\n4. **Uncommitted artifact / Dockerfile-symlink (\u00a74)** \u2014 N/A. No Dockerfile, symlink, workflow, or `entry_points` changes. New subparsers register against an existing `brc_sub` created in slice-1.\n\n5. **Credential-shim modifications under `sandbox/scripts/` (\u00a75)** \u2014 N/A. Diff is scoped to `sandbox/egg_lib/orch_cli.py` (the CLI Python library) plus tests; no `sandbox/scripts/*` touches. The CLI library is invoked from inside the sandbox by the agent itself, so the wrapper-trust-boundary recipe doesn't apply.\n\n6. **Secret leakage (\u00a76)** \u2014 clean. The new `open(file_path, encoding=\"utf-8\")` reads in `_resolve_prose_arg` / `_resolve_files_reviewed_arg` are agent-driven file reads that pipe content into the proposal/ACK/NACK/withdrawal/note body \u2014 exactly the documented purpose. No log emission, no env dumps, no error text that surfaces secrets beyond what the agent already chose to put in the file.

Changes are confined to:\n- `sandbox/egg_lib/orch_cli.py` \u2014 adds `_resolve_prose_arg` / `_resolve_files_reviewed_arg` helpers, plumbs `--summary-file` / `--reason-file` / `--files-reviewed-file` / `--note-file` and stdin sentinel `-` into `consensus propose / ack / nack / withdraw`, registers `brc resolve-obligation` and `brc read-peer-artifact` subparsers + cmd handlers.\n- Two new test files (parametrised prose round-trip and brc-subcommand coverage). No production-code changes outside `orch_cli.py`.\n\n### Lens-by-lens findings \u2014 none blocking\n\n1. **Cross-file allowlist mismatch (\u00a71)** \u2014 clean. `_VALID_BRC_HISTORY_PHASES` is an intentional mirror of `_VALID_PHASES` in `sandbox/egg_agent_tools/handlers/brc.py`; the handler remains the source of truth (verified via Read of the handler) and the CLI's `choices=` is a usability check. Drift would only narrow the CLI surface, not widen access.\n\n2. **Handler-vs-validator path mismatch (\u00a72)** \u2014 clean. `cmd_brc_resolve_obligation` and `cmd_brc_read_peer_artifact` invoke the same `_handlers.brc_resolve_obligation` / `_handlers.brc_read_peer_artifact` functions the MCP server calls. No bypass route \u2014 every authorization gate (producer-cannot-self-resolve in resolve-obligation, the risk_analyst R2 cross-pipeline-read hardening that ignores caller-supplied `pipeline_id` in read-peer-artifact) is enforced server-side and unchanged. The docstring on `cmd_brc_read_peer_artifact` explicitly calls out this server-side identifier resolution.\n\n3. **Information disclosure / authz bypass (\u00a73)** \u2014 clean. No new public endpoints, no widened trust boundary. `cmd_consensus_nack`'s stdout `print(f\"NACK sent by {role} for {args.producer_role}: {reason_text}\")` echoes the resolved reason locally to the invoking agent; same audience as the old `args.reason` line \u2014 no new audience.\n\n4. **Uncommitted artifact / Dockerfile-symlink (\u00a74)** \u2014 N/A. No Dockerfile, symlink, workflow, or `entry_points` changes. New subparsers register against an existing `brc_sub` created in slice-1.\n\n5. **Credential-shim modifications under `sandbox/scripts/` (\u00a75)** \u2014 N/A. Diff is scoped to `sandbox/egg_lib/orch_cli.py` (the CLI Python library) plus tests; no `sandbox/scripts/*` touches. The CLI library is invoked from inside the sandbox by the agent itself, so the wrapper-trust-boundary recipe doesn't apply.\n\n6. **Secret leakage (\u00a76)** \u2014 clean. The new `open(file_path, encoding=\"utf-8\")` reads in `_resolve_prose_arg` / `_resolve_files_reviewed_arg` are agent-driven file reads that pipe content into the proposal/ACK/NACK/withdrawal/note body \u2014 exactly the documented purpose. No log emission, no env dumps, no error text that surfaces secrets beyond what the agent already chose to put in the file. The deprecation-warning text in `_emit_argv_prose_deprecation` echoes the arg *name* (`--reason`, `--summary`, \u2026), never the value, so a stderr regression to argv prose never leaks the prose itself into agent-visible warning output.\n\n7. **Cross-file OWASP top-10 (\u00a77)** \u2014 clean. No injection sinks introduced (no SQL, no HTML, no `eval`/`exec`, no `subprocess` with shell=True). The new file reads use a fixed `encoding=\"utf-8\"` (no auto-detection that could be steered) and the parsed content flows into a JSON request body via the existing transport layer.\n\n8. **Agent-supplied paths \u2192 read-only file access (\u00a78)** \u2014 does NOT apply here, but I considered it carefully because it's the lens-criterion most likely to look applicable on first read. `_resolve_prose_arg` / `_resolve_files_reviewed_arg` do `open(file_path)` on an unconstrained, agent-supplied path.

Registered under `brc_sub` parent parser at orch_cli.py:4299 (sibling of next-action / get-state / list-blocking), `--reviewer-role` and `--producer-role` are `required=True`, `--commit-sha` and `--note` / `--note-file` are optional. Wired to `cmd_brc_resolve_obligation` at orch_cli.py:3233.\n\nAC2: Round-trip against the orchestrator succeeds.\n- VERIFIED. `cmd_brc_resolve_obligation` imports the existing `handlers.brc.brc_resolve_obligation` (already shipped, handlers/brc.py:843), constructs the request dict with the same keys the handler reads (`reviewer_role`, `producer_role`, optional `commit_sha`, optional `note`), and prints a human-readable line on success. `test_happy_path_no_note` patches the handler, invokes `cmd_brc_resolve_obligation` with the minimal namespace, and asserts the captured request contains `reviewer_role == \"reviewer_contract\"` and `producer_role == \"coder\"` with optional fields absent. `test_commit_sha_threaded_when_set` confirms `--commit-sha` threading.\n\nAC3: Help text mirrors the MCP-tool description.\n- VERIFIED. Help string (orch_cli.py:4288-4297) cites #2338, mentions slice-6 deletion rationale, and describes the producer-self-resolution restriction. `test_help_advertises_flags` asserts `--reviewer-role`, `--producer-role`, `--commit-sha`, `--note-file` all appear in help output.\n\nAC4: Prose `--note` exercised via stdin AND via `--note-file PATH`.\n- VERIFIED. `test_note_via_file_round_trips` writes a multi-line note containing `$COMMIT` + backticks to disk and asserts byte-equality on the captured request. `test_note_via_stdin_sentinel` pipes a multi-line payload through stdin via `--note -` and asserts byte-equality. Both channels use the shared `_resolve_prose_arg(required=False)` helper, so the same shell-metachar safety guarantees apply.\n\n### TASK-5-3 \u2014 `egg-orch brc read-peer-artifact` (acceptance criteria verbatim)\n\nAC1: CLI subcommand registered.\n- VERIFIED. Registered under `brc_sub` at orch_cli.py:4351, wired to `cmd_brc_read_peer_artifact` (orch_cli.py:3293). `--phase` is required with `choices=_VALID_BRC_HISTORY_PHASES` (orch_cli.py:766, mirrors `_VALID_PHASES` in handlers/brc.py:912 \u2014 kept as local tuple per the docstring rationale to avoid import-at-parser-build-time of the handler package). `test_phase_choices_restricted` confirms argparse rejects unknown phases at parse time.\n\nAC2: Matches handler behaviour for slice-scoped and unattributed reads.\n- VERIFIED. CLI is a structural pass-through: builds the request dict with `phase`, `include_unattributed` (default True), and optional `peer_role` / `message_type` / `limit` / `cursor` only when set, then delegates to `handlers.brc.brc_read_peer_artifact`. The slice-scoped resolution and `-implement-unattributed.json` merge are the handler's responsibility (handlers/brc.py:1001+) \u2014 the CLI does not duplicate that logic. The `--no-include-unattributed` argparse flag (`dest=include_unattributed, action=\"store_false\", default=True`) correctly flips the handler argument; `test_no_include_unattributed_flips_default` asserts `captured[\"include_unattributed\"] is False`. The caller-supplied `pipeline_id` is intentionally ignored by the handler for cross-pipeline-read hardening \u2014 the CLI docstring (orch_cli.py:3303-3314) acknowledges this and preserves the positional only for argparse-shape consistency.\n\nAC3: Pagination tested with `--limit` + `--cursor` round-trip.\n- VERIFIED. `test_limit_and_cursor_round_trip` configures the handler stub to return `{next_cursor: \"OPAQUE_TOKEN_v2\"}`, invokes the CLI with `limit=10, cursor=\"OPAQUE_TOKEN_v1\"`, asserts both fields are forwarded into the request, and asserts the response's `next_cursor` surfaces on stdout for the wrapper to read. Stdout is always JSON (`print_json(resp)`) regardless of `--json`, matching the docstring's \"mirrors brc_get_state's CLI shape\" claim.\n\n### Cross-task observations (non-blocking)\n- `--message-type` is `action=\"append\"` so a single-value invocation produces a 1-element list, which the handler accepts (handler docstring confirms list/scalar normalisation). `test_message_type_filter_is_list` covers the multi-value case.\n- `_VALID_BRC_HISTORY_PHASES` (orch_cli.py:766) is a local tuple intentionally duplicated from `handlers/brc.py:_VALID_PHASES`. If the handler ever adds a phase, the CLI choices need updating in lockstep \u2014 minor maintenance hazard but no current bug. (Not a contract-blocker; reviewer_code may want to flag.)\n- The slice-1 BRC tests (30), prose-arg tests (76), phase tests (5), and brc adversarial tests (13) all pass under `pytest tests/sandbox/egg_lib/` \u2014 124 tests, 0 failures. handlers/brc + handlers/brc_memory_adversarial (168 tests) regression-clean. No regressions detected against the proposal's \"306 tests pass\" claim within reviewable scope.\n\n### Phase-status consistency\nSlice-5 status is still `pending` in the contract (no task statuses moved yet \u2014 coder typically marks tasks complete at confirm). No phase-marked-complete-with-pending-tasks red flag at this proposal stage; the consensus state is `PROPOSED` for coder, which is correct.\n\nAll three acceptance criteria sections (TASK-5-1, TASK-5-2, TASK-5-3) are objectively met by the cited code + tests.

Wired to `cmd_brc_resolve_obligation` at orch_cli.py:3233.\n\nAC2: Round-trip against the orchestrator succeeds.\n- VERIFIED. `cmd_brc_resolve_obligation` imports the existing `handlers.brc.brc_resolve_obligation` (already shipped, handlers/brc.py:843), constructs the request dict with the same keys the handler reads (`reviewer_role`, `producer_role`, optional `commit_sha`, optional `note`), and prints a human-readable line on success. `test_happy_path_no_note` patches the handler, invokes `cmd_brc_resolve_obligation` with the minimal namespace, and asserts the captured request contains `reviewer_role == \"reviewer_contract\"` and `producer_role == \"coder\"` with optional fields absent. `test_commit_sha_threaded_when_set` confirms `--commit-sha` threading.\n\nAC3: Help text mirrors the MCP-tool description.\n- VERIFIED. Help string (orch_cli.py:4288-4297) cites #2338, mentions slice-6 deletion rationale, and describes the producer-self-resolution restriction. `test_help_advertises_flags` asserts `--reviewer-role`, `--producer-role`, `--commit-sha`, `--note-file` all appear in help output.\n\nAC4: Prose `--note` exercised via stdin AND via `--note-file PATH`.\n- VERIFIED. `test_note_via_file_round_trips` writes a multi-line note containing `$COMMIT` + backticks to disk and asserts byte-equality on the captured request. `test_note_via_stdin_sentinel` pipes a multi-line payload through stdin via `--note -` and asserts byte-equality. Both channels use the shared `_resolve_prose_arg(required=False)` helper, so the same shell-metachar safety guarantees apply.\n\n### TASK-5-3 \u2014 `egg-orch brc read-peer-artifact` (acceptance criteria verbatim)\n\nAC1: CLI subcommand registered.\n- VERIFIED. Registered under `brc_sub` at orch_cli.py:4351, wired to `cmd_brc_read_peer_artifact` (orch_cli.py:3293). `--phase` is required with `choices=_VALID_BRC_HISTORY_PHASES` (orch_cli.py:766, mirrors `_VALID_PHASES` in handlers/brc.py:912 \u2014 kept as local tuple per the docstring rationale to avoid import-at-parser-build-time of the handler package). `test_phase_choices_restricted` confirms argparse rejects unknown phases at parse time.\n\nAC2: Matches handler behaviour for slice-scoped and unattributed reads.\n- VERIFIED. CLI is a structural pass-through: builds the request dict with `phase`, `include_unattributed` (default True), and optional `peer_role` / `message_type` / `limit` / `cursor` only when set, then delegates to `handlers.brc.brc_read_peer_artifact`. The slice-scoped resolution and `-implement-unattributed.json` merge are the handler's responsibility (handlers/brc.py:1001+) \u2014 the CLI does not duplicate that logic. The `--no-include-unattributed` argparse flag (`dest=include_unattributed, action=\"store_false\", default=True`) correctly flips the handler argument; `test_no_include_unattributed_flips_default` asserts `captured[\"include_unattributed\"] is False`. The caller-supplied `pipeline_id` is intentionally ignored by the handler for cross-pipeline-read hardening \u2014 the CLI docstring (orch_cli.py:3303-3314) acknowledges this and preserves the positional only for argparse-shape consistency.\n\nAC3: Pagination tested with `--limit` + `--cursor` round-trip.\n- VERIFIED. `test_limit_and_cursor_round_trip` configures the handler stub to return `{next_cursor: \"OPAQUE_TOKEN_v2\"}`, invokes the CLI with `limit=10, cursor=\"OPAQUE_TOKEN_v1\"`, asserts both fields are forwarded into the request, and asserts the response's `next_cursor` surfaces on stdout for the wrapper to read. Stdout is always JSON (`print_json(resp)`) regardless of `--json`, matching the docstring's \"mirrors brc_get_state's CLI shape\" claim.\n\n### Cross-task observations (non-blocking)\n- `--message-type` is `action=\"append\"` so a single-value invocation produces a 1-element list, which the handler accepts (handler docstring confirms list/scalar normalisation). `test_message_type_filter_is_list` covers the multi-value case.\n- `_VALID_BRC_HISTORY_PHASES` (orch_cli.py:766) is a local tuple intentionally duplicated from `handlers/brc.py:_VALID_PHASES`. If the handler ever adds a phase, the CLI choices need updating in lockstep \u2014 minor maintenance hazard but no current bug. (Not a contract-blocker; reviewer_code may want to flag.)\n- The slice-1 BRC tests (30), prose-arg tests (76), phase tests (5), and brc adversarial tests (13) all pass under `pytest tests/sandbox/egg_lib/` \u2014 124 tests, 0 failures. handlers/brc + handlers/brc_memory_adversarial (168 tests) regression-clean. No regressions detected against the proposal's \"306 tests pass\" claim within reviewable scope.\n\n### Phase-status consistency\nSlice-5 status is still `pending` in the contract (no task statuses moved yet \u2014 coder typically marks tasks complete at confirm). No phase-marked-complete-with-pending-tasks red flag at this proposal stage; the consensus state is `PROPOSED` for coder, which is correct.\n\nAll three acceptance criteria sections (TASK-5-1, TASK-5-2, TASK-5-3) are objectively met by the cited code + tests.

Implementation is correct end-to-end and the test surface is thorough.\n\n**Walked the prose-arg plumbing.** `_resolve_prose_arg` (orch_cli.py:807-866) correctly handles all six channel combinations: (file-only), (stdin sentinel only), (argv only with deprecation), (file + sentinel = mutex error exit 2), (file + argv literal = mutex error exit 2), (none + required = error exit 2). `argv_set` includes the `-` sentinel by design, but the `stdin_set` check is consulted first in both mutex tests so the disambiguation is correct. `_resolve_files_reviewed_arg` (orch_cli.py:869-911) implements one-path-per-line semantics, strips blank lines and `#`-comment lines, and rejects the dual-channel case. The CLI surface is permissive on missing prose (handler is single source of truth on length validation per the docstring rationale) and only enforces presence on `--files-reviewed[-file]` in the cmd functions where downstream serialization needs a non-empty list.\n\n**Walked the new `brc` subcommands.** `cmd_brc_resolve_obligation` (orch_cli.py:3233-3287) threads `--reviewer-role` / `--producer-role` (both required) plus optional `--commit-sha` / `--note` (with the shared prose plumbing) into the existing `brc_resolve_obligation` handler \u2014 no orchestrator-side change needed. `cmd_brc_read_peer_artifact` (orch_cli.py:3290-3344) builds a request dict from `--phase` (argparse-validated against `_VALID_BRC_HISTORY_PHASES`), optional `--peer-role`, repeatable `--message-type` (`action=\"append\"`), `--limit`, `--cursor`, and `--no-include-unattributed` (`action=\"store_false\"`, default True). The handler signature on `brc_read_peer_artifact` (handlers/brc.py:1001-1222) accepts the dict shape verbatim. Output is JSON regardless of `--json` \u2014 comment correctly notes this mirrors `brc_get_state` and is required for pagination tokens to round-trip.\n\n**Verified the test surface (`tests/sandbox/egg_lib/test_orch_cli_prose_args.py`, 76 parametrised tests).** The PROSE_PAYLOADS set covers the seven `#2741` failure modes (`$VAR`, backticks + newline, `$()` command-sub, shell control operators, embedded newline + tab, UTF-8/emoji, quote-and-escape mix). Each is round-tripped through `--reason-file`, `--reason -`, and `--reason \"literal\"` channels on `consensus ack` / `nack` / `withdraw`, and through `--summary-file` / `--summary -` / `--summary \"literal\"` on `consensus propose`. Byte-equality is asserted against the orchestrator-fake's captured request dict. The argv-path tests assert `DeprecationWarning` fires with the offending flag name in the message. `test_file_payload_path_unchanged_no_warning` correctly guards that the pre-existing `--file PATH` JSON-payload route (#1738) is NOT deprecated \u2014 only per-arg argv channels are. `TestParserHelpAdvertisesNewFlags` smoke-tests `--help` advertises the new flags so wrapper authors can discover them. The `tests/sandbox/egg_lib/test_orch_cli_brc.py` extensions for `resolve-obligation` (6 tests) and `read-peer-artifact` (8 tests) cover happy paths, the prose-arg channels on `--note`, pagination cursor round-trip, `--no-include-unattributed` flip, argparse phase-choice rejection, and parent-parser registration.\n\n**Backward compat is clean.** The argparse changes drop `required=True` on `--summary` / `--reason` / `--files-reviewed`, with the resolution helpers taking over the presence check. Existing callers passing argv prose continue to work end-to-end \u2014 they just write a one-line DeprecationWarning to stderr (visible by default because the egg-orch entrypoint is the symlinked file itself, so `__name__ == \"__main__\"` and Python's default filter `default::DeprecationWarning:__main__` lets it through). The `consensus_wrapper.py` is unaffected \u2014 its only consensus invocation is `egg-orch consensus confirmed` (orch_cli.py:617-633) which has no prose argv.\n\n### Non-blocking\n\n- **`orchestrator/routes/pipelines.py:12392, 12520, 12532` prompts** still teach agents the argv `--summary \"...\"` / `--reason \"...\"` / `--files-reviewed \"f1\" \"f2\"` form, and will start emitting DeprecationWarnings every time an agent follows the literal example. This is out-of-scope for the slice-5 coder boundary (`sandbox/egg_lib/orch_cli.py` only), but worth opening a follow-up to rewrite those prompt strings to use the `--summary-file` / `--reason -` channels \u2014 otherwise the deprecation noise the wrapper bash regression-guard relies on becomes background hum and stops surfacing the actual #2741 reintroductions.\n- **Inconsistent error semantics across `_resolve_prose_arg` / `_resolve_files_reviewed_arg`.** The first calls `sys.exit(2)` directly (raises SystemExit); the second also calls `sys.exit(2)` on the dual-channel case but the cmd-level \"missing files-reviewed\" branch uses `print(...); return 2`. Both paths are exit-code-2 equivalent so callers don't observe a difference, but the test file has to use both `pytest.raises(SystemExit)` and `assert rc == 2` to cover the surface. Consider funnelling the cmd-level \"missing files-reviewed\" branch through a helper that does `sys.exit(2)` to remove the asymmetry, or rename the helpers to make the exit semantics explicit.\n- **`_resolve_files_reviewed_arg` does not preserve quoted paths** containing leading `#`. A path that legitimately starts with `#` (rare, but possible \u2014 e.g., a hash-prefixed temp dir) would be silently dropped as a comment. A wrapper authoring the manifest can guard against this by URL-quoting, but a one-sentence callout in the help text (\"# at line start is treated as a comment; escape with leading whitespace if your path begins with #\") would prevent the foot-gun.\n- **`_VALID_BRC_HISTORY_PHASES`** is duplicated between `orch_cli.py:765` and `handlers/brc.py:_VALID_PHASES`.

Implementation is correct end-to-end and the test surface is thorough.\n\n**Walked the prose-arg plumbing.** `_resolve_prose_arg` (orch_cli.py:807-866) correctly handles all six channel combinations: (file-only), (stdin sentinel only), (argv only with deprecation), (file + sentinel = mutex error exit 2), (file + argv literal = mutex error exit 2), (none + required = error exit 2). `argv_set` includes the `-` sentinel by design, but the `stdin_set` check is consulted first in both mutex tests so the disambiguation is correct. `_resolve_files_reviewed_arg` (orch_cli.py:869-911) implements one-path-per-line semantics, strips blank lines and `#`-comment lines, and rejects the dual-channel case. The CLI surface is permissive on missing prose (handler is single source of truth on length validation per the docstring rationale) and only enforces presence on `--files-reviewed[-file]` in the cmd functions where downstream serialization needs a non-empty list.\n\n**Walked the new `brc` subcommands.** `cmd_brc_resolve_obligation` (orch_cli.py:3233-3287) threads `--reviewer-role` / `--producer-role` (both required) plus optional `--commit-sha` / `--note` (with the shared prose plumbing) into the existing `brc_resolve_obligation` handler \u2014 no orchestrator-side change needed. `cmd_brc_read_peer_artifact` (orch_cli.py:3290-3344) builds a request dict from `--phase` (argparse-validated against `_VALID_BRC_HISTORY_PHASES`), optional `--peer-role`, repeatable `--message-type` (`action=\"append\"`), `--limit`, `--cursor`, and `--no-include-unattributed` (`action=\"store_false\"`, default True). The handler signature on `brc_read_peer_artifact` (handlers/brc.py:1001-1222) accepts the dict shape verbatim. Output is JSON regardless of `--json` \u2014 comment correctly notes this mirrors `brc_get_state` and is required for pagination tokens to round-trip.\n\n**Verified the test surface (`tests/sandbox/egg_lib/test_orch_cli_prose_args.py`, 76 parametrised tests).** The PROSE_PAYLOADS set covers the seven `#2741` failure modes (`$VAR`, backticks + newline, `$()` command-sub, shell control operators, embedded newline + tab, UTF-8/emoji, quote-and-escape mix). Each is round-tripped through `--reason-file`, `--reason -`, and `--reason \"literal\"` channels on `consensus ack` / `nack` / `withdraw`, and through `--summary-file` / `--summary -` / `--summary \"literal\"` on `consensus propose`. Byte-equality is asserted against the orchestrator-fake's captured request dict. The argv-path tests assert `DeprecationWarning` fires with the offending flag name in the message. `test_file_payload_path_unchanged_no_warning` correctly guards that the pre-existing `--file PATH` JSON-payload route (#1738) is NOT deprecated \u2014 only per-arg argv channels are. `TestParserHelpAdvertisesNewFlags` smoke-tests `--help` advertises the new flags so wrapper authors can discover them. The `tests/sandbox/egg_lib/test_orch_cli_brc.py` extensions for `resolve-obligation` (6 tests) and `read-peer-artifact` (8 tests) cover happy paths, the prose-arg channels on `--note`, pagination cursor round-trip, `--no-include-unattributed` flip, argparse phase-choice rejection, and parent-parser registration.\n\n**Backward compat is clean.** The argparse changes drop `required=True` on `--summary` / `--reason` / `--files-reviewed`, with the resolution helpers taking over the presence check. Existing callers passing argv prose continue to work end-to-end \u2014 they just write a one-line DeprecationWarning to stderr (visible by default because the egg-orch entrypoint is the symlinked file itself, so `__name__ == \"__main__\"` and Python's default filter `default::DeprecationWarning:__main__` lets it through). The `consensus_wrapper.py` is unaffected \u2014 its only consensus invocation is `egg-orch consensus confirmed` (orch_cli.py:617-633) which has no prose argv.\n\n### Non-blocking\n\n- **`orchestrator/routes/pipelines.py:12392, 12520, 12532` prompts** still teach agents the argv `--summary \"...\"` / `--reason \"...\"` / `--files-reviewed \"f1\" \"f2\"` form, and will start emitting DeprecationWarnings every time an agent follows the literal example. This is out-of-scope for the slice-5 coder boundary (`sandbox/egg_lib/orch_cli.py` only), but worth opening a follow-up to rewrite those prompt strings to use the `--summary-file` / `--reason -` channels \u2014 otherwise the deprecation noise the wrapper bash regression-guard relies on becomes background hum and stops surfacing the actual #2741 reintroductions.\n- **Inconsistent error semantics across `_resolve_prose_arg` / `_resolve_files_reviewed_arg`.** The first calls `sys.exit(2)` directly (raises SystemExit); the second also calls `sys.exit(2)` on the dual-channel case but the cmd-level \"missing files-reviewed\" branch uses `print(...); return 2`. Both paths are exit-code-2 equivalent so callers don't observe a difference, but the test file has to use both `pytest.raises(SystemExit)` and `assert rc == 2` to cover the surface. Consider funnelling the cmd-level \"missing files-reviewed\" branch through a helper that does `sys.exit(2)` to remove the asymmetry, or rename the helpers to make the exit semantics explicit.\n- **`_resolve_files_reviewed_arg` does not preserve quoted paths** containing leading `#`. A path that legitimately starts with `#` (rare, but possible \u2014 e.g., a hash-prefixed temp dir) would be silently dropped as a comment. A wrapper authoring the manifest can guard against this by URL-quoting, but a one-sentence callout in the help text (\"# at line start is treated as a comment; escape with leading whitespace if your path begins with #\") would prevent the foot-gun.\n- **`_VALID_BRC_HISTORY_PHASES`** is duplicated between `orch_cli.py:765` and `handlers/brc.py:_VALID_PHASES`. The comment explains the deliberate avoidance of import-time handler coupling, which is reasonable; a `# Keep in sync with handlers/brc.py:_VALID_PHASES` annotation on both ends would make the implicit contract explicit.

Not blocking this proposal \u2014 the user-facing CLI works end-to-end, the MCP tools work end-to-end, the drift is purely informational.\n- **sandbox/egg_agent_tools/handlers/brc.py:859,1004** \u2014 Related to the above: handler docstrings for `brc_resolve_obligation` (\"No CLI counterpart: this is a net-new capability added in #2338\") and `brc_read_peer_artifact` (\"No CLI counterpart (decision-8) \u2026 so reviewers never have to hand-grep JSON off disk\") are now stale. A reader of the handler source is told there is no CLI; a reader of the new docs is told one was added. Same disposition as above \u2014 the coder's scope excluded the handler file, but the docstrings should land before slice-6.\n- **sandbox/egg_lib/orch_cli.py:107-112,154-163** \u2014 `_resolve_prose_arg` / `_resolve_files_reviewed_arg` catch `OSError` on file read but not `UnicodeDecodeError`. A binary or wrong-encoding file passed to `--reason-file` would surface as a Python traceback rather than a clean `Error: failed to read \u2026: invalid UTF-8 \u2026`. Minor UX nit \u2014 fail-fast is still loud, just not graceful.

Read that diff as if you'd never seen the prior version. Apply your lens (security threat-model, concurrency races, contract AC, line-by-line bugs, silent-fallback shapes \u2014 whichever your role owns) to the delta itself, not to whether your previous concerns were satisfied. **Mandate 2 is bounded to this delta** \u2014 it does NOT ask you to re-traverse the whole accumulated surface from earlier cycles; that work was amortized when you first reviewed those commits.\n\nBoth mandates have equal weight. If (1) passes but (2) finds new issues, you NACK. ACK requires both pass.\n\n**The named-blockers anchor is a known trap. Every reviewer lens has a mandate-2 in its own territory** \u2014 security has newly-introduced threat surfaces, concurrency has newly-introduced races, contract has newly-introduced AC drift, code has newly-introduced line-by-line bugs. The four issues that escaped PR #2724 to the GitHub bot were all of code-lens shape (`${ANSWER}` as bare Python, deprecated `datetime.utcnow()`, non-atomic write, bare `except: pass`) \u2014 the persistent reviewer correctly answered mandate 1 (\"did prior issues get fixed? yes\") and skipped mandate 2 (\"does this delta introduce new issues? actually yes\"). The shape generalizes: whatever your lens, this delta can introduce issues your prior NACK didn't name. Watching the producer deliver a targeted fix pulls strongly toward \"verify my fix-request landed \u2192 ACK.\" Recognize the pull and do mandate 2 anyway.\n\n**How to execute mandate 2:**\n\n- Read each new hunk as an operator who's about to copy-paste / run / integrate it. Would this code execute as written? Would these docs send a copy-paster down a working path?\n- Apply every rubric pass to the new hunks. New issues outside the scope of your prior NACK are blocking; your prior NACK does not bound this re-review.\n- **Fresh-reviewer simulation.** Before issuing your v2 verdict, ask: would a reviewer who has only seen this delta (the commits since your last review) with no NACK history ACK this? If you can't argue yes from that diff alone, NACK.\n- **External-bot anchor.** Imagine `egg-reviewer[bot]` reads only this delta (the commits since your last review) with no NACK context. What would it flag? Anything it'd flag, you should NACK first.\n\n**Your v2 verdict must enumerate both halves** so mandate 2 doesn't silently disappear from the record:\n\n- (a) Which v1 blockers you verified-fixed (mandate 1).\n- (b) What new issues you audited-and-did-not-find (mandate 2). Name the specific shapes you checked \u2014 not \"reviewed thoroughly,\" but \"checked for silent fallbacks, doc-snippet executability, API-deprecation, atomicity of file writes.\" If you can't enumerate (b), you haven't done mandate 2.\n\n**Re-reviews are cheap by design.** Your amortized context means the work is \"read the delta, apply your rubric, decide\" \u2014 minutes, not hours. NACK without hesitance; the orchestrator absorbs cycles. Two NACKs on the same producer where the second names new findings is the correct trajectory, not goalpost-moving.

Reviewed three files: the 18-test adversarial probe suite, the 403-line MCP-surface latency-baseline integration test, and the synthetic JSON placeholder.\n\n### Concurrency lens \u2014 what I checked\n\n1. **Race conditions in test isolation (adversarial suite)** \u2014 `tests/sandbox/egg_lib/test_orch_cli_prose_args_adversarial.py` uses pytest's `tmp_path` for filesystem isolation (per-test + per-worker under xdist), `monkeypatch.setattr(\"sys.stdin\", io.StringIO(...))` for stdin sandboxing (test-scoped, reverted on teardown), `monkeypatch.setenv` for env vars (test-scoped), and `unittest.mock.patch` for handler stubbing (test-scoped). No shared module-level mutable state introduced. No pytest-xdist worker-collision risk.\n\n2. **Race conditions in the baseline-capture integration test** \u2014 `integration_tests/test_mcp_baseline_capture.py` polls a single pipeline's `/status` endpoint from a single test process; no multi-actor mutation paths. The `qualifier = f\"mcp-baseline-{os.getpid()}-{int(time.time())}\"` (line ~370) gives a per-process-per-second-unique pipeline_id so concurrent CI jobs against the same cluster don't collide on the state-store row.\n\n3. **Deadlocks** \u2014 None. No locks acquired. `_call_tool` uses `async with streamablehttp_client(url) as (read, write, _): async with ClientSession(...) as session:` \u2014 properly nested async contexts that exit in reverse order (session closes before client transport closes). `asyncio.run(_run())` creates a fresh event loop per invocation; no module-import-time `asyncio.Lock` issue.\n\n4. **Async-context leakage** \u2014 `_call_tool` (line ~122) uses `asyncio.run()` in a sync test context.

Reviewed three files: the 18-test adversarial probe suite, the 403-line MCP-surface latency-baseline integration test, and the synthetic JSON placeholder.\n\n### Concurrency lens \u2014 what I checked\n\n1. **Race conditions in test isolation (adversarial suite)** \u2014 `tests/sandbox/egg_lib/test_orch_cli_prose_args_adversarial.py` uses pytest's `tmp_path` for filesystem isolation (per-test + per-worker under xdist), `monkeypatch.setattr(\"sys.stdin\", io.StringIO(...))` for stdin sandboxing (test-scoped, reverted on teardown), `monkeypatch.setenv` for env vars (test-scoped), and `unittest.mock.patch` for handler stubbing (test-scoped). No shared module-level mutable state introduced. No pytest-xdist worker-collision risk.\n\n2. **Race conditions in the baseline-capture integration test** \u2014 `integration_tests/test_mcp_baseline_capture.py` polls a single pipeline's `/status` endpoint from a single test process; no multi-actor mutation paths. The `qualifier = f\"mcp-baseline-{os.getpid()}-{int(time.time())}\"` (line ~370) gives a per-process-per-second-unique pipeline_id so concurrent CI jobs against the same cluster don't collide on the state-store row.\n\n3. **Deadlocks** \u2014 None. No locks acquired. `_call_tool` uses `async with streamablehttp_client(url) as (read, write, _): async with ClientSession(...) as session:` \u2014 properly nested async contexts that exit in reverse order (session closes before client transport closes). `asyncio.run(_run())` creates a fresh event loop per invocation; no module-import-time `asyncio.Lock` issue.\n\n4. **Async-context leakage** \u2014 `_call_tool` (line ~122) uses `asyncio.run()` in a sync test context. Each call gets a fresh event loop that closes cleanly when the coroutine returns. The MCP async context managers are entered inside the coroutine and exit before `asyncio.run()` returns. No background tasks created via `asyncio.create_task` (so no dropped-task-reference issue per the lens criteria). No `time.sleep()` inside async code \u2014 the only `time.sleep(_PIPELINE_POLL_INTERVAL_SEC)` calls (lines ~380, 387) are in the sync polling loop in `test_capture_one_run`, which is a synchronous pytest test method, not an async function.\n\n5. **Retry-storm patterns** \u2014 The polling loop in `test_capture_one_run` has a 5-second interval and a 25-minute hard cap. Single-process test, single-pipeline target. NOT a thundering-herd shape (the `:00` / `:30` alignment concern doesn't apply \u2014 a kubectl-gated integration test runs at most once per CI invocation).

For the synthetic placeholder this is irrelevant (it's written once, by the committing developer's hand).

`tests/sandbox/egg_lib/test_orch_cli_prose_args_adversarial.py` (added under coder v2 commit 3b63b83cc per the dual-role producer/reviewer pattern). Implementation is sound.\n\n### What I checked\n\n- **Syntax / lint.** `python3 -c \"import ast; ast.parse(open('integration_tests/test_mcp_baseline_capture.py').read())\"` succeeds. `ruff check integration_tests/test_mcp_baseline_capture.py` returns \"All checks passed!\" The `except FileNotFoundError, subprocess.TimeoutExpired:` / `except TypeError, ValueError:` / `except urllib.error.URLError, TimeoutError, ConnectionError:` patterns on lines 172, 210, 369 are valid Python 3.14 (PEP 758 \u2014 unparenthesized multiple-exception form, equivalent to `except (X, Y, \u2026)`). Verified empirically with disassembly (`BUILD_TUPLE 2/3`) and with raise-and-catch round-trips. The project pins `requires-python = \">=3.14\"` so this is portable.\n\n- **Fixture wiring.** `egg_stack` (conftest.py:340 \u2014 kubectl-gated skip), `orchestrator_url` (conftest.py:357), and `orchestrator_mcp_url` (conftest.py:381 \u2014 health-gated skip via the local-overlay `hostPort: 9850`) all exist as session-scoped. The new `_healthy_gateway_or_skip` fixture (test_mcp_baseline_capture.py:293) layers gateway-health check on top, mirroring the same guard `test_orchestrator_mcp_contract.py` uses for dummy-credentialed CI clusters. Skip chain is correct: no kubectl \u2192 skip; no MCP hostPort \u2192 skip; gateway degraded \u2192 skip; `submit_task` rejected \u2192 skip. Test only runs end-to-end on a fully wired k3s + real-LLM stack, which matches the acceptance criteria.\n\n- **Capture logic.** `_call_tool` mirrors `test_orchestrator_mcp_contract.py`'s helper (deliberately inlined to keep test-to-test coupling out). `_get_pipeline_status` reads `/api/v1/pipelines//status` which the orchestrator populates with `concurrent.agents[].{role,started_at,elapsed_seconds,exit_code}`. `_agents_to_samples` computes `end_ts` from the orchestrator's server-side clock (`start_dt + elapsed_seconds`) rather than the test client's wall-clock, which correctly handles a desynced capture host. Polling loop has a 25-min hard cap (`_PIPELINE_POLL_TIMEOUT_SEC`), 5s interval, and writes a partial baseline + fails with a clear \"did not reach terminal status\" message on timeout. `_PIPELINE_TERMINAL_STATUSES` covers both lowercase (`completed`, `failed`) and uppercase (`PR_READY`, `FAILED`) forms the orchestrator uses across surfaces. \u2713\n\n- **Aggregation math.** `_aggregate` uses `statistics.quantiles(..., n=20, method=\"inclusive\")` to derive 19 cut-points; index 9 \u2248 p50, index 18 \u2248 p95. Correct interpretation. Single-sample fall-back (`p50 = p95 = durations_sorted[0]`) and zero-sample fall-back (all zeros) are sensible. \u2713\n\n- **JSON schema & placeholder.** The committed `.egg-state/agent-outputs/latency-mcp-baseline.json` has `_meta.synthetic: true` and a thorough `_meta.synthetic_reason` explaining the regeneration path. `samples` and `aggregate` are populated with plausible synthetic values (5 roles, durations 120-270s, p50=150, p95=270). Slice-6 reads only `samples` and `aggregate` per the schema doc, so `_meta` additions are forward-safe. The test's `_write_baseline` correctly sets `synthetic: false` when it actually runs \u2014 so a real-capture run overwrites the placeholder cleanly.\n\n- **Adversarial-probe file (tests/sandbox/egg_lib/test_orch_cli_prose_args_adversarial.py).** Already reviewed end-to-end in my v2 ACK on the coder (the file was pulled in under the coder v2 commit per the dual-role pattern). 18 tests covering #2741 file-read error paths (non-UTF-8 + missing-path), one-path-per-line manifest edges (CRLF, leading whitespace, comments-only), empty-channel semantics (empty argv, empty stdin, trailing-newline preservation), `brc resolve-obligation` stdout / `--json` / HandlerError-no-traceback / argv `--note` deprecation warning, and `brc read-peer-artifact` `--message-type \u00d73` list / handler `--limit 0` rejection / `include_unattributed` default-True / no caller-pipeline_id leakage / argparse phase-choice rejection. The bug surfaced in tester v1 (`UnicodeDecodeError` slipping past `except OSError`) is the kind of edge this file is designed to catch \u2014 and it caught it.\n\n- **submit_task issue-number safety.** The capture test calls `submit_task` with `issue_number=999_999_002` against `repo=\"test-owner/test-repo\"`. If the orchestrator can't load the issue (dummy GH creds on the test cluster), `submit_task` returns `{\"error\": ...}` and the test skips with a clear message. The qualifier-per-run (`mcp-baseline-{pid}-{ts}`) avoids state-store 409s on repeated runs. \u2713\n\n- **No silent fallbacks introduced.** Every skip path emits a clear message naming the unmet precondition. The pass/fail assertions are explicit about partial-baseline vs empty-samples vs terminal-but-empty. The `subprocess.run`/`urlopen` exception chains are conservative (transient errors keep polling; permanent errors propagate or skip). \u2713\n\n### Attestation\n\nProposal text reports \"all 142 tests in tests/sandbox/egg_lib/ now pass (76 prose-args + 18 prose-args adversarial + 30 brc + 13 brc adversarial + 5 phase) + broader regression 193 tests; ruff check + ruff format clean.\" This is consistent with the `_resolve_prose_arg` rc=2 contract change and the new adversarial probes. The integration test (task-5-7) is necessarily skipped in the agent sandbox (no kubectl, no k3s) \u2014 the synthetic placeholder is the committed slice-5 artifact and the test runs against a real stack in CI / on a developer's local k3s.\n\n### Non-blocking\n\n- **`except X, Y:` PEP 758 form is uncommon in the rest of the codebase.** I spot-checked: most modules use `except (X, Y):` with explicit parentheses. The PEP 758 form is valid Python 3.14+ but visually it reads like Python 2's `except X, name:` (which had different semantics \u2014 name was the variable). A reader unfamiliar with PEP 758 may file a NACK on a future re-pass. Either add a one-line comment near the first occurrence (\"PEP 758: unparenthesized tuple, equivalent to `except (X, Y):`\") or convert to the parenthesized form for codebase-style consistency. Either is fine.\n- **`integration_tests/test_mcp_baseline_capture.py:172,210,369` use the comma form** \u2014 see above. Same suggestion.\n- **`issue_number=999_999_002`** is hardcoded with no reservation note. If GH ever actually has that issue, the orchestrator might do real work against it. Worth adding a comment \"this issue number is intentionally outside the realistic range; if a real issue lands here, pick a different reserved number\" \u2014 or pull it into a constant `_BASELINE_RESERVED_ISSUE_NUMBER = 999_999_002` at the top of the file with the rationale.\n- **The capture test, when it runs successfully, overwrites the synthetic baseline.** A developer who runs `pytest integration_tests/test_mcp_baseline_capture.py` would silently see the working tree change. A `pytest.mark.modifies_repo` marker or a final `print(\"baseline file overwritten at \u2026 \u2014 review and commit if intended\")` in `_write_baseline` would surface the side-effect.\n- **`_aggregate`** computes p50 / p95 using `statistics.quantiles(..., n=20, method=\"inclusive\")` \u2014 index 9 is the 50th percentile across 20 buckets (5%-step cut-points), index 18 is the 95th. With only 5 samples (the synthetic placeholder), this is heavily interpolated. The math is correct, but slice-6's comparison test will be comparing percentiles derived from very few samples. A docstring note in `_aggregate` (\"n=5 typical from a 5-role consensus run; percentile resolution is coarse \u2014 slice-6 should treat the comparison as a sanity bound, not a precision metric\") would set expectations.\n- **`_egg_git_sha`** runs `git rev-parse HEAD` with `timeout=5`; an `OSError` from a missing git binary already triggers `FileNotFoundError`, but if `subprocess.run` itself raises `OSError` from another source (rare but possible \u2014 e.g. permissions on cwd), the bare `try` would propagate. Tightening to `except (OSError, FileNotFoundError, subprocess.TimeoutExpired):` (Python 3.14 form: `except OSError, FileNotFoundError, subprocess.TimeoutExpired:`) would be conservative. Not blocking \u2014 the failure mode is unlikely and the empty-string fallback only affects the baseline's `_meta.egg_git_sha` field, which slice-6 doesn't consume.\n", + "metadata": { + "payload": { + "artifact_references": [ + "integration_tests/test_mcp_baseline_capture.py", + ".egg-state/agent-outputs/latency-mcp-baseline.json", + "tests/sandbox/egg_lib/test_orch_cli_prose_args_adversarial.py", + "integration_tests/conftest.py" + ], + "reason": "\nReviewed commit 78cc951e9 (task-5-7) plus the tester's hardening at `tests/sandbox/egg_lib/test_orch_cli_prose_args_adversarial.py` (added under coder v2 commit 3b63b83cc per the dual-role producer/reviewer pattern).

The `subprocess.run`/`urlopen` exception chains are conservative (transient errors keep polling; permanent errors propagate or skip). \u2713\n\n### Attestation\n\nProposal text reports \"all 142 tests in tests/sandbox/egg_lib/ now pass (76 prose-args + 18 prose-args adversarial + 30 brc + 13 brc adversarial + 5 phase) + broader regression 193 tests; ruff check + ruff format clean.\" This is consistent with the `_resolve_prose_arg` rc=2 contract change and the new adversarial probes. The integration test (task-5-7) is necessarily skipped in the agent sandbox (no kubectl, no k3s) \u2014 the synthetic placeholder is the committed slice-5 artifact and the test runs against a real stack in CI / on a developer's local k3s.\n\n### Non-blocking\n\n- **`except X, Y:` PEP 758 form is uncommon in the rest of the codebase.** I spot-checked: most modules use `except (X, Y):` with explicit parentheses. The PEP 758 form is valid Python 3.14+ but visually it reads like Python 2's `except X, name:` (which had different semantics \u2014 name was the variable). A reader unfamiliar with PEP 758 may file a NACK on a future re-pass. Either add a one-line comment near the first occurrence (\"PEP 758: unparenthesized tuple, equivalent to `except (X, Y):`\") or convert to the parenthesized form for codebase-style consistency. Either is fine.\n- **`integration_tests/test_mcp_baseline_capture.py:172,210,369` use the comma form** \u2014 see above. Same suggestion.\n- **`issue_number=999_999_002`** is hardcoded with no reservation note. If GH ever actually has that issue, the orchestrator might do real work against it. Worth adding a comment \"this issue number is intentionally outside the realistic range; if a real issue lands here, pick a different reserved number\" \u2014 or pull it into a constant `_BASELINE_RESERVED_ISSUE_NUMBER = 999_999_002` at the top of the file with the rationale.\n- **The capture test, when it runs successfully, overwrites the synthetic baseline.** A developer who runs `pytest integration_tests/test_mcp_baseline_capture.py` would silently see the working tree change. A `pytest.mark.modifies_repo` marker or a final `print(\"baseline file overwritten at \u2026 \u2014 review and commit if intended\")` in `_write_baseline` would surface the side-effect.\n- **`_aggregate`** computes p50 / p95 using `statistics.quantiles(..., n=20, method=\"inclusive\")` \u2014 index 9 is the 50th percentile across 20 buckets (5%-step cut-points), index 18 is the 95th. With only 5 samples (the synthetic placeholder), this is heavily interpolated. The math is correct, but slice-6's comparison test will be comparing percentiles derived from very few samples. A docstring note in `_aggregate` (\"n=5 typical from a 5-role consensus run; percentile resolution is coarse \u2014 slice-6 should treat the comparison as a sanity bound, not a precision metric\") would set expectations.\n- **`_egg_git_sha`** runs `git rev-parse HEAD` with `timeout=5`; an `OSError` from a missing git binary already triggers `FileNotFoundError`, but if `subprocess.run` itself raises `OSError` from another source (rare but possible \u2014 e.g. permissions on cwd), the bare `try` would propagate. Tightening to `except (OSError, FileNotFoundError, subprocess.TimeoutExpired):` (Python 3.14 form: `except OSError, FileNotFoundError, subprocess.TimeoutExpired:`) would be conservative. Not blocking \u2014 the failure mode is unlikely and the empty-string fallback only affects the baseline's `_meta.egg_git_sha` field, which slice-6 doesn't consume.\n", + "ack_version": 1 + }, + "version": 1, + "slice_id": "slice-5" + }, + "timestamp": "2026-06-03T02:09:20.196124+00:00", + "phase": "implement" + }, + { + "id": "62a5e973-59f3-4b", + "pipeline_id": "issue-2908-impl2", + "from_role": "orchestrator", + "to_role": "tester", + "message_type": "STATUS", + "subject": "Ready to confirm \u2014 all confirm preconditions satisfied", + "body": "Your proposal (version 1) is ready to confirm \u2014 all blocking reviews are clear and global confirm preconditions are met.

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

Two helpers in sandbox/egg_lib/orch_cli.py — `_resolve_prose_arg` and `_resolve_files_reviewed_arg` — handle channel selection (file → stdin → argv), enforce mutual exclusion, and emit DeprecationWarning on argv prose. `--files-reviewed-file` follows the architect v2 one-path-per-line semantics (# comments and blanks stripped). The existing `consensus propose --file` JSON-payload path (#1738) is preserved unchanged and does NOT emit the deprecation — only per-arg argv channels are deprecated. + +(2) task-5-2 — `egg-orch brc resolve-obligation` CLI subcommand wraps `mcp__brc__resolve_obligation` (#2338). Required: --reviewer-role, --producer-role. Optional: --commit-sha, --note (with prose-arg plumbing). + +(3) task-5-3 — `egg-orch brc read-peer-artifact` CLI subcommand wraps `mcp__brc__read_peer_artifact`. Required: --phase.

Drift would only narrow the CLI surface, not widen access. + +2. **Handler-vs-validator path mismatch (§2)** — clean. `cmd_brc_resolve_obligation` and `cmd_brc_read_peer_artifact` invoke the same `_handlers.brc_resolve_obligation` / `_handlers.brc_read_peer_artifact` functions the MCP server calls. No bypass route — every authorization gate (producer-cannot-self-resolve in resolve-obligation, the risk_analyst R2 cross-pipeline-read hardening that ignores caller-supplied `pipeline_id` in read-peer-artifact) is enforced server-side and unchanged. The docstring on `cmd_brc_read_peer_artifact` explicitly calls out this server-side identifier resolution. + +3. **Information disclosure / authz bypass (§3)** — clean. No new public endpoints, no widened trust boundary. `cmd_consensus_nack`'s stdout `print(f"NACK sent by {role} for {args.producer_role}: {reason_text}")` echoes the resolved reason locally to the invoking agent; same audience as the old `args.reason` line — no new audience. + +4. **Uncommitted artifact / Dockerfile-symlink (§4)** — N/A. No Dockerfile, symlink, workflow, or `entry_points` changes.

CLI is a structural pass-through: builds the request dict with `phase`, `include_unattributed` (default True), and optional `peer_role` / `message_type` / `limit` / `cursor` only when set, then delegates to `handlers.brc.brc_read_peer_artifact`. The slice-scoped resolution and `-implement-unattributed.json` merge are the handler's responsibility (handlers/brc.py:1001+) — the CLI does not duplicate that logic. The `--no-include-unattributed` argparse flag (`dest=include_unattributed, action="store_false", default=True`) correctly flips the handler argument; `test_no_include_unattributed_flips_default` asserts `captured["include_unattributed"] is False`. The caller-supplied `pipeline_id` is intentionally ignored by the handler for cross-pipeline-read hardening — the CLI docstring (orch_cli.py:3303-3314) acknowledges this and preserves the positional only for argparse-shape consistency. + +AC3: Pagination tested with `--limit` + `--cursor` round-trip. +- VERIFIED. `test_limit_and_cursor_round_trip` configures the handler stub to return `{next_cursor: "OPAQUE_TOKEN_v2"}`, invokes the CLI with `limit=10, cursor="OPAQUE_TOKEN_v1"`, asserts both fields are forwarded into the request, and asserts the response's `next_cursor` surfaces on stdout for the wrapper to read. Stdout is always JSON (`print_json(resp)`) regardless of `--json`, matching the docstring's "mirrors brc_get_state's CLI shape" claim. + +### Cross-task observations (non-blocking) +- `--message-type` is `action="append"` so a single-value invocation produces a 1-element list, which the handler accepts (handler docstring confirms list/scalar normalisation). `test_message_type_filter_is_list` covers the multi-value case. +- `_VALID_BRC_HISTORY_PHASES` (orch_cli.py:766) is a local tuple intentionally duplicated from `handlers/brc.py:_VALID_PHASES`. If the handler ever adds a phase, the CLI choices need updating in lockstep — minor maintenance hazard but no current bug. (Not a contract-blocker; reviewer_code may want to flag.) +- The slice-1 BRC tests (30), prose-arg tests (76), phase tests (5), and brc adversarial tests (13) all pass under `pytest tests/sandbox/egg_lib/` — 124 tests, 0 failures. handlers/brc + handlers/brc_memory_adversarial (168 tests) regression-clean.

The\ + \ slice-scoped resolution and `-implement-unattributed.json` merge\ + \ are the handler's responsibility (handlers/brc.py:1001+) \u2014 the CLI does\ + \ not duplicate that logic.

The caller-supplied `pipeline_id` is intentionally ignored by the\ + \ handler for cross-pipeline-read hardening \u2014 the CLI docstring (orch_cli.py:3303-3314)\ + \ acknowledges this and preserves the positional only for argparse-shape consistency.\n\ + \nAC3: Pagination tested with `--limit` + `--cursor` round-trip.\n- VERIFIED.\ + \ `test_limit_and_cursor_round_trip` configures the handler stub to return `{next_cursor:\ + \ \"OPAQUE_TOKEN_v2\"}`, invokes the CLI with `limit=10, cursor=\"OPAQUE_TOKEN_v1\"\ + `, asserts both fields are forwarded into the request, and asserts the response's\ + \ `next_cursor` surfaces on stdout for the wrapper to read.

Each is round-tripped through `--reason-file`, `--reason -`, and `--reason "literal"` channels on `consensus ack` / `nack` / `withdraw`, and through `--summary-file` / `--summary -` / `--summary "literal"` on `consensus propose`. Byte-equality is asserted against the orchestrator-fake's captured request dict. The argv-path tests assert `DeprecationWarning` fires with the offending flag name in the message. `test_file_payload_path_unchanged_no_warning` correctly guards that the pre-existing `--file PATH` JSON-payload route (#1738) is NOT deprecated — only per-arg argv channels are. `TestParserHelpAdvertisesNewFlags` smoke-tests `--help` advertises the new flags so wrapper authors can discover them. The `tests/sandbox/egg_lib/test_orch_cli_brc.py` extensions for `resolve-obligation` (6 tests) and `read-peer-artifact` (8 tests) cover happy paths, the prose-arg channels on `--note`, pagination cursor round-trip, `--no-include-unattributed` flip, argparse phase-choice rejection, and parent-parser registration. + +**Backward compat is clean.** The argparse changes drop `required=True` on `--summary` / `--reason` / `--files-reviewed`, with the resolution helpers taking over the presence check. Existing callers passing argv prose continue to work end-to-end — they just write a one-line DeprecationWarning to stderr (visible by default because the egg-orch entrypoint is the symlinked file itself, so `__name__ == "__main__"` and Python's default filter `default::DeprecationWarning:__main__` lets it through). The `consensus_wrapper.py` is unaffected — its only consensus invocation is `egg-orch consensus confirmed` (orch_cli.py:617-633) which has no prose argv. + +### Non-blocking + +- **`orchestrator/routes/pipelines.py:12392, 12520, 12532` prompts** still teach agents the argv `--summary "..."` / `--reason "..."` / `--files-reviewed "f1" "f2"` form, and will start emitting DeprecationWarnings every time an agent follows the literal example. This is out-of-scope for the slice-5 coder boundary (`sandbox/egg_lib/orch_cli.py` only), but worth opening a follow-up to rewrite those prompt strings to use the `--summary-file` / `--reason -` channels — otherwise the deprecation noise the wrapper bash regression-guard relies on becomes background hum and stops surfacing the actual #2741 reintroductions. +- **Inconsistent error semantics across `_resolve_prose_arg` / `_resolve_files_reviewed_arg`.** The first calls `sys.exit(2)` directly (raises SystemExit); the second also calls `sys.exit(2)` on the dual-channel case but the cmd-level "missing files-reviewed" branch uses `print(...); return 2`. Both paths are exit-code-2 equivalent so callers don't observe a difference, but the test file has to use both `pytest.raises(SystemExit)` and `assert rc == 2` to cover the surface. Consider funnelling the cmd-level "missing files-reviewed" branch through a helper that does `sys.exit(2)` to remove the asymmetry, or rename the helpers to make the exit semantics explicit. +- **`_resolve_files_reviewed_arg` does not preserve quoted paths** containing leading `#`. A path that legitimately starts with `#` (rare, but possible — e.g., a hash-prefixed temp dir) would be silently dropped as a comment. A wrapper authoring the manifest can guard against this by URL-quoting, but a one-sentence callout in the help text ("# at line start is treated as a comment; escape with leading whitespace if your path begins with #") would prevent the foot-gun. +- **`_VALID_BRC_HISTORY_PHASES`** is duplicated between `orch_cli.py:765` and `handlers/brc.py:_VALID_PHASES`. The comment explains the deliberate avoidance of import-time handler coupling, which is reasonable; a `# Keep in sync with handlers/brc.py:_VALID_PHASES` annotation on both ends would make the implicit contract explicit.

The `tests/sandbox/egg_lib/test_orch_cli_brc.py` extensions for `resolve-obligation`\ + \ (6 tests) and `read-peer-artifact` (8 tests) cover happy paths, the prose-arg\ + \ channels on `--note`, pagination cursor round-trip, `--no-include-unattributed`\ + \ flip, argparse phase-choice rejection, and parent-parser registration.\n\n\ + **Backward compat is clean.** The argparse changes drop `required=True` on `--summary`\ + \ / `--reason` / `--files-reviewed`, with the resolution helpers taking over\ + \ the presence check. Existing callers passing argv prose continue to work end-to-end\ + \ \u2014 they just write a one-line DeprecationWarning to stderr (visible by\ + \ default because the egg-orch entrypoint is the symlinked file itself, so `__name__\ + \ == \"__main__\"` and Python's default filter `default::DeprecationWarning:__main__`\ + \ lets it through). The `consensus_wrapper.py` is unaffected \u2014 its only\ + \ consensus invocation is `egg-orch consensus confirmed` (orch_cli.py:617-633)\ + \ which has no prose argv.\n\n### Non-blocking\n\n- **`orchestrator/routes/pipelines.py:12392,\ + \ 12520, 12532` prompts** still teach agents the argv `--summary \"...\"` /\ + \ `--reason \"...\"` / `--files-reviewed \"f1\" \"f2\"` form, and will start\ + \ emitting DeprecationWarnings every time an agent follows the literal example.\ + \ This is out-of-scope for the slice-5 coder boundary (`sandbox/egg_lib/orch_cli.py`\ + \ only), but worth opening a follow-up to rewrite those prompt strings to use\ + \ the `--summary-file` / `--reason -` channels \u2014 otherwise the deprecation\ + \ noise the wrapper bash regression-guard relies on becomes background hum and\ + \ stops surfacing the actual #2741 reintroductions.\n- **Inconsistent error\ + \ semantics across `_resolve_prose_arg` / `_resolve_files_reviewed_arg`.** The\ + \ first calls `sys.exit(2)` directly (raises SystemExit); the second also calls\ + \ `sys.exit(2)` on the dual-channel case but the cmd-level \"missing files-reviewed\"\ + \ branch uses `print(...); return 2`. Both paths are exit-code-2 equivalent\ + \ so callers don't observe a difference, but the test file has to use both `pytest.raises(SystemExit)`\ + \ and `assert rc == 2` to cover the surface. Consider funnelling the cmd-level\ + \ \"missing files-reviewed\" branch through a helper that does `sys.exit(2)`\ + \ to remove the asymmetry, or rename the helpers to make the exit semantics\ + \ explicit.\n- **`_resolve_files_reviewed_arg` does not preserve quoted paths**\ + \ containing leading `#`. A path that legitimately starts with `#` (rare, but\ + \ possible \u2014 e.g., a hash-prefixed temp dir) would be silently dropped\ + \ as a comment. A wrapper authoring the manifest can guard against this by URL-quoting,\ + \ but a one-sentence callout in the help text (\"# at line start is treated\ + \ as a comment; escape with leading whitespace if your path begins with #\"\ + ) would prevent the foot-gun.\n- **`_VALID_BRC_HISTORY_PHASES`** is duplicated\ + \ between `orch_cli.py:765` and `handlers/brc.py:_VALID_PHASES`. The comment\ + \ explains the deliberate avoidance of import-time handler coupling, which is\ + \ reasonable; a `# Keep in sync with handlers/brc.py:_VALID_PHASES` annotation\ + \ on both ends would make the implicit contract explicit.

Read that diff as if you'd never seen the prior version. Apply your lens (security threat-model, concurrency races, contract AC, line-by-line bugs, silent-fallback shapes — whichever your role owns) to the delta itself, not to whether your previous concerns were satisfied. **Mandate 2 is bounded to this delta** — it does NOT ask you to re-traverse the whole accumulated surface from earlier cycles; that work was amortized when you first reviewed those commits. + +Both mandates have equal weight. If (1) passes but (2) finds new issues, you NACK. ACK requires both pass. + +**The named-blockers anchor is a known trap. Every reviewer lens has a mandate-2 in its own territory** — security has newly-introduced threat surfaces, concurrency has newly-introduced races, contract has newly-introduced AC drift, code has newly-introduced line-by-line bugs. The four issues that escaped PR #2724 to the GitHub bot were all of code-lens shape (`${ANSWER}` as bare Python, deprecated `datetime.utcnow()`, non-atomic write, bare `except: pass`) — the persistent reviewer correctly answered mandate 1 ("did prior issues get fixed? yes") and skipped mandate 2 ("does this delta introduce new issues? actually yes"). The shape generalizes: whatever your lens, this delta can introduce issues your prior NACK didn't name. Watching the producer deliver a targeted fix pulls strongly toward "verify my fix-request landed → ACK." Recognize the pull and do mandate 2 anyway. + +**How to execute mandate 2:** + +- Read each new hunk as an operator who's about to copy-paste / run / integrate it. Would this code execute as written? Would these docs send a copy-paster down a working path? +- Apply every rubric pass to the new hunks. New issues outside the scope of your prior NACK are blocking; your prior NACK does not bound this re-review. +- **Fresh-reviewer simulation.** Before issuing your v2 verdict, ask: would a reviewer who has only seen this delta (the commits since your last review) with no NACK history ACK this? If you can't argue yes from that diff alone, NACK. +- **External-bot anchor.** Imagine `egg-reviewer[bot]` reads only this delta (the commits since your last review) with no NACK context. What would it flag? Anything it'd flag, you should NACK first. + +**Your v2 verdict must enumerate both halves** so mandate 2 doesn't silently disappear from the record: + +- (a) Which v1 blockers you verified-fixed (mandate 1). +- (b) What new issues you audited-and-did-not-find (mandate 2). Name the specific shapes you checked — not "reviewed thoroughly," but "checked for silent fallbacks, doc-snippet executability, API-deprecation, atomicity of file writes." If you can't enumerate (b), you haven't done mandate 2. + +**Re-reviews are cheap by design.** Your amortized context means the work is "read the delta, apply your rubric, decide" — minutes, not hours. NACK without hesitance; the orchestrator absorbs cycles. Two NACKs on the same producer where the second names new findings is the correct trajectory, not goalpost-moving. The downstream GitHub reviewer should find nothing in this delta. Anything it catches that lives in this cycle's diff is a miss attributable to this re-review. + +````yaml +id: 3549f717-d152-44 +phase: implement +metadata: + payload: + summary: "Slice-5 task-5-4 documenter v2: address reviewer_code v1 NACK.

No shared module-level mutable state introduced. No pytest-xdist worker-collision risk. + +2. **Race conditions in the baseline-capture integration test** — `integration_tests/test_mcp_baseline_capture.py` polls a single pipeline's `/status` endpoint from a single test process; no multi-actor mutation paths. The `qualifier = f"mcp-baseline-{os.getpid()}-{int(time.time())}"` (line ~370) gives a per-process-per-second-unique pipeline_id so concurrent CI jobs against the same cluster don't collide on the state-store row. + +3. **Deadlocks** — None. No locks acquired. `_call_tool` uses `async with streamablehttp_client(url) as (read, write, _): async with ClientSession(...) as session:` — properly nested async contexts that exit in reverse order (session closes before client transport closes). `asyncio.run(_run())` creates a fresh event loop per invocation; no module-import-time `asyncio.Lock` issue. + +4. **Async-context leakage** — `_call_tool` (line ~122) uses `asyncio.run()` in a sync test context. Each call gets a fresh event loop that closes cleanly when the coroutine returns. The MCP async context managers are entered inside the coroutine and exit before `asyncio.run()` returns. No background tasks created via `asyncio.create_task` (so no dropped-task-reference issue per the lens criteria). No `time.sleep()` inside async code — the only `time.sleep(_PIPELINE_POLL_INTERVAL_SEC)` calls (lines ~380, 387) are in the sync polling loop in `test_capture_one_run`, which is a synchronous pytest test method, not an async function. + +5. **Retry-storm patterns** — The polling loop in `test_capture_one_run` has a 5-second interval and a 25-minute hard cap. Single-process test, single-pipeline target. NOT a thundering-herd shape (the `:00` / `:30` alignment concern doesn't apply — a kubectl-gated integration test runs at most once per CI invocation). The hard `_PIPELINE_POLL_TIMEOUT_SEC = 25 * 60` cap explicitly prevents a wedged pipeline from turning into an open-ended hang. + +6. **Resource-cleanup ordering** — `urllib.request.urlopen(..., timeout=15)` and `urllib.request.urlopen(..., timeout=10)` (in `_healthy_gateway_or_skip`) both have explicit timeouts. `subprocess.run([..., "git", "rev-parse", "HEAD"], timeout=5)` has a timeout. All three guard against hangs. Context managers (`with urllib.request.urlopen(...) as resp:`) close the connection deterministically. + +7. **Subprocess pipe-draining** — `_egg_git_sha()` uses `capture_output=True` which captures both stdout and stderr into memory; `subprocess.run` drains both pipes before returning. No risk of a child blocking on a full pipe the parent never drains. + +8. **BRC-protocol invariants** — The tester adds NO orchestrator code, NO handler code, NO message-bus code. The baseline-capture test only READS `/api/v1/pipelines//status` and invokes the `submit_task` MCP tool — neither path touches BRC consensus, `--since` cursor threading, version-stale-rejection logic, `stale_reviewers` invalidation, or `max_flip_flops` enforcement. + +9. **Heartbeat-stall windows (#2012)** — The 25-minute pipeline poll runs inside a pytest test, NOT inside a heartbeat-bearing agent path.

If a future CI config opts the integration suite into pytest-xdist, or two parallel CI jobs concurrently capture against the same checkout, the writes can interleave and produce a corrupted JSON file. Slice-6 TASK-6-6 reads this file and would then JSONDecodeError. Hardening: write to a sibling tmp path (`tmp = _BASELINE_OUTPUT.with_suffix('.json.tmp'); tmp.write_text(...); tmp.replace(_BASELINE_OUTPUT)`) — atomic rename on POSIX.

(task-5-7) plus the tester's hardening at `tests/sandbox/egg_lib/test_orch_cli_prose_args_adversarial.py` (added under coder v2 commit 3b63b83cc per the dual-role producer/reviewer pattern). Implementation is sound. + +### What I checked + +- **Syntax / lint.** `python3 -c "import ast; ast.parse(open('integration_tests/test_mcp_baseline_capture.py').read())"` succeeds. `ruff check integration_tests/test_mcp_baseline_capture.py` returns "All checks passed!" The `except FileNotFoundError, subprocess.TimeoutExpired:` / `except TypeError, ValueError:` / `except urllib.error.URLError, TimeoutError, ConnectionError:` patterns on lines 172, 210, 369 are valid Python 3.14 (PEP 758 — unparenthesized multiple-exception form, equivalent to `except (X, Y, …)`). Verified empirically with disassembly (`BUILD_TUPLE 2/3`) and with raise-and-catch round-trips. The project pins `requires-python = ">=3.14"` so this is portable. + +- **Fixture wiring.** `egg_stack` (conftest.py:340 — kubectl-gated skip), `orchestrator_url` (conftest.py:357), and `orchestrator_mcp_url` (conftest.py:381 — health-gated skip via the local-overlay `hostPort: 9850`) all exist as session-scoped. The new `_healthy_gateway_or_skip` fixture (test_mcp_baseline_capture.py:293) layers gateway-health check on top, mirroring the same guard `test_orchestrator_mcp_contract.py` uses for dummy-credentialed CI clusters. Skip chain is correct: no kubectl → skip; no MCP hostPort → skip; gateway degraded → skip; `submit_task` rejected → skip. Test only runs end-to-end on a fully wired k3s + real-LLM stack, which matches the acceptance criteria. + +- **Capture logic.** `_call_tool` mirrors `test_orchestrator_mcp_contract.py`'s helper (deliberately inlined to keep test-to-test coupling out). `_get_pipeline_status` reads `/api/v1/pipelines//status` which the orchestrator populates with `concurrent.agents[].{role,started_at,elapsed_seconds,exit_code}`. `_agents_to_samples` computes `end_ts` from the orchestrator's server-side clock (`start_dt + elapsed_seconds`) rather than the test client's wall-clock, which correctly handles a desynced capture host. Polling loop has a 25-min hard cap (`_PIPELINE_POLL_TIMEOUT_SEC`), 5s interval, and writes a partial baseline + fails with a clear "did not reach terminal status" message on timeout. `_PIPELINE_TERMINAL_STATUSES` covers both lowercase (`completed`, `failed`) and uppercase (`PR_READY`, `FAILED`) forms the orchestrator uses across surfaces. ✓ + +- **Aggregation math.** `_aggregate` uses `statistics.quantiles(..., n=20, method="inclusive")` to derive 19 cut-points; index 9 ≈ p50, index 18 ≈ p95. Correct interpretation. Single-sample fall-back (`p50 = p95 = durations_sorted[0]`) and zero-sample fall-back (all zeros) are sensible. ✓ + +- **JSON schema & placeholder.** The committed `.egg-state/agent-outputs/latency-mcp-baseline.json` has `_meta.synthetic: true` and a thorough `_meta.synthetic_reason` explaining the regeneration path. `samples` and `aggregate` are populated with plausible synthetic values (5 roles, durations 120-270s, p50=150, p95=270). Slice-6 reads only `samples` and `aggregate` per the schema doc, so `_meta` additions are forward-safe. The test's `_write_baseline` correctly sets `synthetic: false` when it actually runs — so a real-capture run overwrites the placeholder cleanly. + +- **Adversarial-probe file (tests/sandbox/egg_lib/test_orch_cli_prose_args_adversarial.py).** Already reviewed end-to-end in my v2 ACK on the coder (the file was pulled in under the coder v2 commit per the dual-role pattern). 18 tests covering #2741 file-read error paths (non-UTF-8 + missing-path), one-path-per-line manifest edges (CRLF, leading whitespace, comments-only), empty-channel semantics (empty argv, empty stdin, trailing-newline preservation), `brc resolve-obligation` stdout / `--json` / HandlerError-no-traceback / argv `--note` deprecation warning, and `brc read-peer-artifact` `--message-type ×3` list / handler `--limit 0` rejection / `include_unattributed` default-True / no caller-pipeline_id leakage / argparse phase-choice rejection.

With only 5 samples (the synthetic placeholder), this is heavily interpolated. The math is correct, but slice-6's comparison test will be comparing percentiles derived from very few samples. A docstring note in `_aggregate` ("n=5 typical from a 5-role consensus run; percentile resolution is coarse — slice-6 should treat the comparison as a sanity bound, not a precision metric") would set expectations. +- **`_egg_git_sha`** runs `git rev-parse HEAD` with `timeout=5`; an `OSError` from a missing git binary already triggers `FileNotFoundError`, but if `subprocess.run` itself raises `OSError` from another source (rare but possible — e.g. permissions on cwd), the bare `try` would propagate. Tightening to `except (OSError, FileNotFoundError, subprocess.TimeoutExpired):` (Python 3.14 form: `except OSError, FileNotFoundError, subprocess.TimeoutExpired:`) would be conservative.

Implementation\ + \ is sound.\n\n### What I checked\n\n- **Syntax / lint.** `python3 -c \"import\ + \ ast; ast.parse(open('integration_tests/test_mcp_baseline_capture.py').read())\"\ + ` succeeds. `ruff check integration_tests/test_mcp_baseline_capture.py` returns\ + \ \"All checks passed!\" The `except FileNotFoundError, subprocess.TimeoutExpired:`\ + \ / `except TypeError, ValueError:` / `except urllib.error.URLError, TimeoutError,\ + \ ConnectionError:` patterns on lines 172, 210, 369 are valid Python 3.14 (PEP\ + \ 758 \u2014 unparenthesized multiple-exception form, equivalent to `except\ + \ (X, Y, \u2026)`). Verified empirically with disassembly (`BUILD_TUPLE 2/3`)\ + \ and with raise-and-catch round-trips. The project pins `requires-python =\ + \ \">=3.14\"` so this is portable.\n\n- **Fixture wiring.** `egg_stack` (conftest.py:340\ + \ \u2014 kubectl-gated skip), `orchestrator_url` (conftest.py:357), and `orchestrator_mcp_url`\ + \ (conftest.py:381 \u2014 health-gated skip via the local-overlay `hostPort:\ + \ 9850`) all exist as session-scoped. The new `_healthy_gateway_or_skip` fixture\ + \ (test_mcp_baseline_capture.py:293) layers gateway-health check on top, mirroring\ + \ the same guard `test_orchestrator_mcp_contract.py` uses for dummy-credentialed\ + \ CI clusters. Skip chain is correct: no kubectl \u2192 skip; no MCP hostPort\ + \ \u2192 skip; gateway degraded \u2192 skip; `submit_task` rejected \u2192 skip.\ + \ Test only runs end-to-end on a fully wired k3s + real-LLM stack, which matches\ + \ the acceptance criteria.\n\n- **Capture logic.** `_call_tool` mirrors `test_orchestrator_mcp_contract.py`'s\ + \ helper (deliberately inlined to keep test-to-test coupling out). `_get_pipeline_status`\ + \ reads `/api/v1/pipelines//status` which the orchestrator populates with\ + \ `concurrent.agents[].{role,started_at,elapsed_seconds,exit_code}`. `_agents_to_samples`\ + \ computes `end_ts` from the orchestrator's server-side clock (`start_dt + elapsed_seconds`)\ + \ rather than the test client's wall-clock, which correctly handles a desynced\ + \ capture host. Polling loop has a 25-min hard cap (`_PIPELINE_POLL_TIMEOUT_SEC`),\ + \ 5s interval, and writes a partial baseline + fails with a clear \"did not\ + \ reach terminal status\" message on timeout. `_PIPELINE_TERMINAL_STATUSES`\ + \ covers both lowercase (`completed`, `failed`) and uppercase (`PR_READY`, `FAILED`)\ + \ forms the orchestrator uses across surfaces. \u2713\n\n- **Aggregation math.**\ + \ `_aggregate` uses `statistics.quantiles(..., n=20, method=\"inclusive\")`\ + \ to derive 19 cut-points; index 9 \u2248 p50, index 18 \u2248 p95. Correct\ + \ interpretation. Single-sample fall-back (`p50 = p95 = durations_sorted[0]`)\ + \ and zero-sample fall-back (all zeros) are sensible. \u2713\n\n- **JSON schema\ + \ & placeholder.** The committed `.egg-state/agent-outputs/latency-mcp-baseline.json`\ + \ has `_meta.synthetic: true` and a thorough `_meta.synthetic_reason` explaining\ + \ the regeneration path. `samples` and `aggregate` are populated with plausible\ + \ synthetic values (5 roles, durations 120-270s, p50=150, p95=270). Slice-6\ + \ reads only `samples` and `aggregate` per the schema doc, so `_meta` additions\ + \ are forward-safe. The test's `_write_baseline` correctly sets `synthetic:\ + \ false` when it actually runs \u2014 so a real-capture run overwrites the placeholder\ + \ cleanly.\n\n- **Adversarial-probe file (tests/sandbox/egg_lib/test_orch_cli_prose_args_adversarial.py).**\ + \ Already reviewed end-to-end in my v2 ACK on the coder (the file was pulled\ + \ in under the coder v2 commit per the dual-role pattern). 18 tests covering\ + \ #2741 file-read error paths (non-UTF-8 + missing-path), one-path-per-line\ + \ manifest edges (CRLF, leading whitespace, comments-only), empty-channel semantics\ + \ (empty argv, empty stdin, trailing-newline preservation), `brc resolve-obligation`\ + \ stdout / `--json` / HandlerError-no-traceback / argv `--note` deprecation\ + \ warning, and `brc read-peer-artifact` `--message-type \xD73` list / handler\ + \ `--limit 0` rejection / `include_unattributed` default-True / no caller-pipeline_id\ + \ leakage / argparse phase-choice rejection.

It consumes `EGG_PIPELINE_ID` / `EGG_ISSUE_NUMBER` (to resolve the identifier) and `EGG_SLICE_ID` (to pick the per-slice partition for `phase == "implement"`) directly from the environment; `EGG_ORCHESTRATOR_URL` and `EGG_LIFECYCLE_SECRET` do not apply, so missing-secret failures against `read-peer-artifact` are misdiagnosed if you trace them through the HTTP layer. The `brc` surface is additive to the existing `consensus` surface — every prior subcommand under `consensus` keeps working unchanged; the split only reflects that `consensus` is verb-by-state-change (proposes / acks / withdraws) and `brc` is verb-by-read-or-derive (derive-next, list-blocking, read history, resolve obligation). + ## Context PR Surfaces ([#2777](https://github.com/jwbron/egg/issues/2777)) Slice-aware pipelines (issue-mode pipelines with `contract.slices`) open the **Context PR** — `egg//work → main` — up-front at the plan→implement boundary, hard-required and idempotent (#2777).
