Give the review gauntlet a deterministic retry loop for lanes that FAULT
(PIPELINE-FAULT marker, missing verdict sentinel, or a nested graph's own
degraded-run wording) without ever re-running a lane that reached a real
verdict.
- graph.yaml: the four lane maps route to a new `retry_gate` script node
(static `next: verdict_gate`; emits `_next: build_items` to retry).
initial_state gains lane_attempts / kept_results / retry_lanes /
review_incomplete / gauntlet_started_at. settings.timeout 24000 -> 69600
(3 passes x 2 attempts x 11400 + 1200 margin).
- scripts/retry_gate.py (new): stashes every lane report that ran
(completed and faulted alike) and restores reports a re-run pass
overwrote with []; classifies with verdict_gate.py's sentinel regexes
verbatim; counts attempts; retries while attempts < 3 and inside a
45600 s wall-clock budget; otherwise records the lane in
review_incomplete and falls through. Crash guard appends to
signals_error and never retries.
- scripts/signals.py: stamps gauntlet_started_at before the git work so a
failed diff still starts the clock.
- scripts/build_items.py: retry pass emits items only for retry_lanes
(with attempt numbers), adds a `retried:` note to lanes_summary, resets
retry_lanes; falsy-guarded stamp fallback; crash guard appends to
signals_error and preserves lanes_summary.
- Tests: hermetic python3-guarded script tests for retry_gate /
build_items / signals, graph wiring + initial_state pins, sentinel and
LANE_KEYS cross-pins, retry-budget envelope vs settings.timeout, a
first-pass golden payload, and an engine-level executor test proving a
script `_next` back-edge re-fires a static fan-out and an empty map
re-run clears its collect_into.
Plan: PLAN-review-retry section A items 1-3 and 5. Verdict/report surface
(section A items 4 and 6) is TASK-032.
verdict_gate.py: the code-review critical count is read from render.py's
deterministic summary line (full-shape regex, LAST match wins — a 🔴
quoted inside a finding body or Changes-table row is not a finding); the
raw 🔴 count remains the fail-closed fallback when the line is absent. A
code-review lane whose own rendered verdict line records a pipeline
fault (degraded nested run) now BLOCKS instead of passing as GREEN
(attention), and fault + reds append both blockers. A non-string lane
result item is BLOCKED as malformed, never routed to GREEN.
default_lanes.py: the crash handler now emits the WIDEST safe selection
(code-review ∪ adversary ∪ security) and records a PIPELINE-FAULT in
signals_error so the gate blocks — previously it repaired malformed state
into a NARROWER passable selection with no fault. Probe is added only
when consumer_surface AND a probe_context (local-run recipe) are present,
mirroring build_items' guard, so degraded selection cannot spawn an
INCONCLUSIVE-by-construction probe.
graph.yaml: re-derive the timeout envelope. Agent-node retries each get a
fresh per-attempt budget (agent.rs retry_transient/bounded_attempt) and
the child's "Graph … timed out" matches the transient anchor, so lanes
exceed their child graph's settings.timeout (code-review 11400 > 10800,
adversary 9600 > 9000) and the gauntlet's own timeout covers
max_attempts × lane timeout + margin (2 × 11400 + 1200 = 24000). The
child graphs' internal retry envelopes are deliberately not derived here
(tracked as a follow-up). README/descriptions updated and pinned.
Tests: summary-count/quoted-🔴/fallback/last-match/nested-fault/both-
blockers/malformed-lane, crash-widens-and-records-fault, probe guard,
ALIASES parity with build_items, and e2e render.py → verdict_gate runs.
- 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)
