render.py's empty-diff stub bypass is anchored on the 'PIPELINE-FAULT:'
prefix in reason/attention, but verdict.py's crash guard emitted
'verdict computation error: …' / 'verdict script error: …' without it —
on an empty diff a crashed verdict gate collapsed into the
'No changes to review.' stub and the fail-closed NEEDS-HUMAN verdict
never reached the final report.
- prefix the crash-guard reason and attention entry with PIPELINE-FAULT:
- strengthen the existing crash test to assert the prefix on both fields
- add R5 chained test: empty diff + crash-inducing state piped
verdict.py -> render.py must render the fault, never the stub
- add crash-guard symmetry tests for parse_fault.py / aux_fault.py
(raw non-JSON GRAPH_STATE keeps the fault marker) and a test that a
fault survives the attention[:5] cap alongside 6 user flags
Every llm/agent stage that can die persistently now falls back to a
machine-readable PIPELINE-FAULT sentinel instead of killing the graph:
- review_domain -> branch-local domain_fault marker (banner-prefixed
domain_report the map collects; completeness_gate precedent)
- verify -> verdict (verifier fault renders findings unverified + a
PIPELINE-FAULT attention line)
- parse -> parse_fault -> render (complete NEEDS-HUMAN verdict_out;
render's no-changes stub is bypassed for fault verdicts)
- refine_groups -> cover_gate (deterministic-proposal fallback absorbs
the failure; degradation noted in groups_note)
- aux_lanes -> aux_fault -> synthesize (aux_note fault marker; visible,
never blocking - aux is enrichment)
- synthesize -> verdict (synth_failure marker; keyed off the failure
prefix + non-empty diff, never findings==[], so clean zero-finding
reviews stay MERGE-READY)
verdict.py gains unified fault accounting (R2): any PIPELINE-FAULT in
domain_reports / verifier_output / state fault keys forces NEEDS-HUMAN,
prefix-anchored so a report merely quoting the marker mid-text never
trips it; old 'PIPELINE FAULT' spelling migrated. Faults are prepended
to attention so the [:5] cap can never hide one. Dedicated *_failure
state keys capture engine failure text on every fallback+output_schema
node, keeping the bundled warning baseline at zero.
15 python3-guarded R5 tests: fault paths, quoted-marker precedence,
happy-path byte-compat regression, marker normalization, crash-path
fail-closed (verdict/cover_gate/domain_fault), verifier-fault-on-empty-
diff render, and the no-changes stub regression.
Adversary finding 1: verdict_gate treated any lane report CONTAINING
'PIPELINE-FAULT:' as a lane fault, so a real review quoting the marker
silently bypassed red-finding counting and sentinel parsing. Lane-fault
detection is now precise — only a report that IS the lane_fault.py
marker (starts with it) routes to the fault rule. Adds the missing
regression tests: reds block despite MERGE-READY, NEEDS-HUMAN without
reds passes with attention, probe INCONCLUSIVE blocks with the
environment note, a gate crash fails closed, and a quoting report is
routed to the red rule, not the fault rule.
Adversary finding 2: default_lanes overwrote caller-forced lanes and
dropped the security lane the deterministic signals guaranteed. The
fallback now unions its defaults with caller-forced lanes (canonicalized
via the same aliases build_items uses) and forces security on
auth/deps/exec signals or hardened posture — selection degrades wider,
never narrower, and stays deterministic via a fixed lane order. Tests
cover forced-lane survival, alias canonicalization, unknown-name
tolerance, each security signal, and determinism.
- lane_fault.py + fallback on all four run_* lane nodes: an agent-node
failure is normalized into a PIPELINE-FAULT lane result instead of
killing the graph
- verdict_gate.py: PIPELINE-FAULT lane results block distinctly from
SKIPPED and missing-sentinel; a PIPELINE-FAULT in signals_error blocks
at the gauntlet level
- build_items.py: restructured into main() + fail-closed guard (crash
emits empty lanes + PIPELINE-FAULT) and folds lanes_degraded into
lanes_summary
- parse: state_updates/fallback -> parse_fault.py, which records the
fault in signals_error and jumps to the verdict gate
- select_lanes: state_updates/fallback -> default_lanes.py, a
deterministic wider-never-narrower lane fallback
- verification_commands threaded through parse into run_adversary's
prompt (declared-only, never invented)
- run_probe prompt gains the aborted-attempt reconcile line
- 8 gauntlet_* R5 tests in src/config/request_context.rs (script harness
+ graph interpolation)
Adversary conformance-review fixes for the TASK-017 exec-evidence stage:
- run_checks.py: total-runtime deadline (3300s = node timeout minus margin);
each command gets min(900s, remaining budget), commands past the deadline
are recorded as {cmd, skipped: deadline} entries so in-script handling
stays authoritative instead of the node timeout killing the script from
outside. POSIX hardening: per-command process group (start_new_session)
+ killpg on timeout so hung grandchildren cannot linger; non-POSIX
limitation documented in the docstring.
- graph.yaml: run_checks gains fallback: pipeline_fault; check_criterion
treats SKIPPED records as at-best PARTIAL (unproven, never failed).
- pipeline_fault.py: run_checks-stage attribution grounded in real engine
behavior (script-node fallback writes nothing into state, executor.rs
script arm) — nonempty diff_text proves facts completed, so the fault is
the verification runner; emits 'PIPELINE-FAULT: verification runner
killed'. Empty diff_text still attributes to diff resolution.
- verdict.py: renders skipped records as [SKIPPED] instead of a bogus
[FAIL] exit-? line; non-degraded verdict semantics untouched.
- tests: outer-except ENVIRONMENT degradation, deadline timeout+skip (env
seam ADVERSARY_RUN_CHECKS_DEADLINE_SECS), pipeline_fault stage
attribution (parse / facts / run_checks), check_criterion prompt cites
{{exec_results}}, verdict SKIPPED rendering; run_adversary_script_env
helper for env-carrying invocations.
- cargo fmt violations in 3d7dea9 test code fixed (fmt --check exit 0).
An llm node never persists its completion under `output` (the binding
is transient), so a map branch without state_updates collected the
stale inherited value: deep-research produced `None` findings and
finding-verifier errored on its first item because `output` was absent.
Both maps now declare an explicit output_key and their branch nodes
write it via state_updates. graph.example.yaml's research_subject gets
the same named-key pattern and its branch comment describes it.

sisyphus: Quality bar line in the code-reviewer spawn prompt (omitted when
the task prompt carried none); rigor-aware WARNING handling with
(deferred by quality bar) FOLLOW-UPS tagging; evidence-cited rejection
protocol for [convention] findings (repo convention at file:line or a
recorded plan decision; never for CRITICAL/[correctness]; escalate on
re-raise); rigor-to-posture default map for security-reviewer spawns.
architect: Phase B quality-bar round + other:<label> librarian lane;
Phase E Sisyphus CONTEXT and adversary prompts carry rigor/surfaces and
the plan's Quality bar excerpt; task-close logs rejected-finding lines;
Phase F PR body gains the Quality bar line and Review decisions section;
two new anti-patterns (bare rejections, rigor suppressing CRITICAL).
- Extend the injected Background Jobs prompt guidance: system_notifications
push on completion, collect-only-when-idle wait protocol, and the graph
LLM-node collect-before-final-turn rule
- Mention the system_notifications push in the agent spawning guidance and
in the sisyphus/architect wait-protocol text (agent completions push
notifications too)
- config.example.yaml: max_concurrent_jobs (default 5, 0 = disabled)
- README: features-list entry pointing at the Background-Jobs wiki page
