Reviews no longer fail on formatting. Three changes to how reviewer/gate
verdicts are parsed and how retries reset state:
- Approval leniency: a review that clearly approves in prose passes even
without a structured verdict (proseSignalsClearApproval, with a
revise/reject/negated-approval guard so a rejection is never flipped). Any
APPROVE*/APPROVAL verdict token classifies as approved. Shared by the
reviewer/plan-review parser and the code-review/browser-verification gate.
- Prose + trailing JSON: extractJsonObjectCandidates does a string-aware
balanced-brace scan and prefers the last object, so a model that emits
reasoning prose then a trailing {"verdict":...} payload parses correctly.
An explicit "Verdict:" heading/line still takes precedence over an
incidental/example JSON object.
- Malformed handling: executeWorkflowStep retries the fallback model on
malformed output (not just timeout); malformed gate output becomes a
non-blocking advisory (a genuine parsed REVISE still blocks).
- Retry clears prior terminal step failures (incl. optional gate nodes like
code-review) after the task leaves the mergeable in-review column, so a
retry starts clean without an auto-merge race.
Fail-closed merge / PR-review / mission-verification gates are unchanged.
