attempt_id: attempt-a

run_id: attempt-a

task_id: task-reviewable-csv-importer

evaluation_id: eval-attempt-a

evaluation_decision: approved

decision: promote

rationale: First useful baseline; AC2 still returns a generic error. Promoted to set the frontier so improvement attempts can be measured against it.


attempt_id: attempt-b-prompt-rewrite

run_id: attempt-b-prompt-rewrite

evaluation_id: eval-attempt-b-prompt-rewrite

decision: reject

rationale: Rejected. Prompt-rewrite approach regressed AC3 and did not fix AC2. Filed in the ledger so the next attempt does not retry the same approach.


attempt_id: attempt-c

run_id: attempt-c

evaluation_id: eval-attempt-c

rationale: Promoted to current frontier. AC2 now reports row and column of the offending token; AC1 and AC3 remain passing. Operator promoted after manual review of the evaluation envelope.
