jsonl-board-duplicate-id-consolidation
Verified end-to-end. The solution is written to ~/duplicate-id-consolidation.md.
Since the environment contained only the boardctl binary (no board repo), I reverse-engineered the board format by initializing test boards, then reproduced and fixed each failure case with the real binary.
Task identity is the JSONL id field, not the line. When a lane appends a close/refile row instead of mutating the filing row, boardctl validate emits [error] tasks.jsonl line N: duplicate task id "X" (also line M) and exits 1.
A raw top-level renumbered_from key validates as RESULT: OK but triggers key-uniformity drift and fails --strict-keys (which the installed pre-commit hook uses). The canonical carrier is dup_note, e.g. dup_note="renumbered_from=BT-102" — it passes plain, --strict-keys, and --fail-on dangling-dep with 0 drift.
RESULT: FAIL (3 error(s)).RESULT: OK (0 warning(s)) and hook-equivalent RESULT: OK, with key uniformity: 5/5 rows carry only canon keys (0 drift).OK while the task row stays pending.--dedupe yields duplicate task_completed events; deduping by (tick_number, task_id) yields exactly one on a same-tick retry.The markdown contains the full consolidate.py, the idempotent close-out pattern, exact commands, a verification transcript, and a commit checklist.

{"description": "boardctl validate FAILs a JSONL board with duplicate task ids after lanes append close rows instead of mutating the filing row. Recipe that worked: locate each dup id, classify the pair (same workload refile = delete the appended stub; DIFFERENT finding reusing a taken id = renumber the later row to the next free id and record renumbered_from; appended close beside a still-pending filing row = merge the close fields into the filing row and flip it, then delete the appended line). Line-surgical python edit (load lines, mutate only the matched lines, drop the dup line numbers, write back) so untouched lines stay byte-identical; then boardctl validate must read RESULT: OK before the commit. Two traps: (a) a close-out script must actually PERSIST tasks.jsonl - a version that saves only events/header prints success while the rows stay pending; (b) re-running such a script must dedupe events by (tick, task_id) or it appends duplicate task_complete events.", "environment": "", "language": "", "model": "openrouter/deepseek/deepseek-v4.1-flash", "problem_class": "jsonl-board-duplicate-id-consolidation", "provider": "openrouter", "solved_at": "2026-10-10T18:25:17.563Z", "version": ""}
