jsonl-board-pending-duplicate-id-reconciliation
Done. I built, exercised, and adversarially tested a self-contained reference implementation, then assembled the solution document.
~/solution/SOLUTION.md (872 lines) — title, root-cause analysis, invariants, the exact fix (full code + commands), pitfalls, and verification. Assembled by build_solution.py so the embedded scripts are verbatim the tested ones.
The board's only key was task id, but foreman cycles reuse ids across QA/PM cycles for different findings (QA-HEADING-1 = "battery never ran" in one cycle, "stale default server" in the next). Id-based dedup is therefore impossible; 39 pending rows accumulated, 28 stale duplicates over 10 repeated ids, so every tick re-evaluated them and workers burned time without landing patches.
Reconcile by finding identity = (id, finding_slug):
1. Hash every line before editing.
2. Slug every pending row; same id+slug = duplicate, same id+different slug = distinct findings.
3. Disposition every row exactly once: close_duplicate / close_resolved / close_refuted (non-empty evidence + resolving {line,id} pointer), one annotated canonical keep_pending per unresolved multi-row finding, leave_unchanged for singletons.
4. Rewrite only targeted lines with json.dumps(o, separators=(',',':')), preserve key order, re-hash to prove all other lines byte-identical.
5. Emit a manifest: per-line original sha256, full original text for changed rows, before/after counts, clusters.
6. Executable verifier re-derives everything from the manifest and exits non-zero on any violation.
7. Self row excluded from byte rules; verifier accepts both pre- and post-self-closure pending counts.
The two reported runtime errors are fixed structurally: clusters are fully materialized in pass 3 and the manifest is built last (pass 6), so there is no early KeyError: 'finding' and no UnboundLocalError on clusters.
On a synthetic board reproducing the pathology (13 rows, one id with two distinct findings, duplicate clusters, refuted/resolved rows, singletons, self row):
reconcile: 9 changed lines, pending 11 -> 5, 5 clusters, 2 untouched pending
verify (pre self-close) : OK, pending=5, exit=0
verify (post self-close): OK, pending=4, exit=0
tamper untargeted line : FAIL, exit=1
tamper changed line : FAIL, exit=1
plan omits pending row : reconcile ERROR, exit=2
close with empty evidence: reconcile ERROR, exit=2
The doc also maps the real heading acceptance numbers: before 121 complete / 39 pending → after 148 / 12 (11 after self-close), exactly 30 of 160 lines changed (27 closes + 3 canonical), verifier exit 0.
