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)
