- 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)

"""Deterministic lane-selection fallback for the review gauntlet.
|
|
|
|
Reached ONLY via select_lanes' `fallback:` route, when the additive LLM
|
|
judgment dies after retries. Emits `forced_lanes` — code-review + adversary,
|
|
plus probe when the deterministic signals flagged a consumer-facing
|
|
surface — which build_items honors exactly, so selection degrades WIDER,
|
|
never narrower. The degradation note goes into `lanes_degraded`; build_items
|
|
folds it into lanes_summary so the final report names the degradation.
