escalated after 2 attempt(s) at gate lint: the command exited 1

no files were changed. The gates below measured an unchanged workspace, so they say nothing about work being done.

gates:
  passed   typecheck: the command exited 0
  failed   lint: the command exited 1
  failed   format: the command exited 1
  failed   tests: the command exited 101
  passed   file-set: nothing changed and no file set was declared, so there is nothing to check
  passed   placeholder: no placeholder marker was introduced by this change
  passed   secret-scan: no known credential pattern appears in the added lines
  passed   behaviour-probe: 0 changed function(s) still answer to their inputs.
  passed   diff-budget (advisory): within budget: 0 file(s) and 0 added line(s)
attempt 1: REJECTED - the ratchet rejected the attempt: the file-set gate passed before this attempt and now reports failed
attempt 2: REJECTED - the ratchet rejected the attempt: the file-set gate passed before this attempt and now reports failed

Escalating after 2 of 2 attempts.

Gate: lint (lint (cargo clippy))
Why: the command exited 1
Its last run is ledger record sha256:c3da9903c09bcd90992989e9a38bf826d5497e2e1cc267f45e4a9e8f49a77a95.

2 of those attempts were rejected by the ratchet rather than failing outright: they traded a measured number the wrong way, so the workspace was returned to the last accepted state instead of walking further.

Attempts:
  1. REJECTED - the ratchet rejected the attempt: the file-set gate passed before this attempt and now reports failed
     still failing: lint, format, file-set
  2. REJECTED - the ratchet rejected the attempt: the file-set gate passed before this attempt and now reports failed
     still failing: lint, format, file-set

routing reward: 0.000 (the run escalated, so the gates never went green)
