Certification scope

CERTIFIED(local, fixture scope) — Verity scoped re-bench 2026-10-26, standing card eclipse-scholarly-witness-mcp-2026-10-26-2.json (card -1 PARTIAL(local, fixture scope) retained append-only and superseded), scope language exact from the card: sealed snapshot srw-20261026-ea6bc90cf693, duplicate-bearing audit receipts recompute MATCH on both verification surfaces with tamper-by-name divergence, receipts carry the full §9.3 field set incl. the CC-BY attribution, disposition answers carry the §6.3 as-of block on all branches, work_resolve surfaces per-pin source labels, and the reinstatement-only population shape is consistent under amendment A3. Fixture signer (FIXTURE_SIGNED) — no live/production claim; PubMed errata coverage window 2023-01-01..2026-10-26 remains disclosed in the manifest known_bounds.

What it does

Answer from a sealed snapshot only: which disposition notices (retraction, correction, concern) the named sources carry for a work, which source attests each one, and where the sources disagree
Source disagreements sealed as open divergence records — data for the reader, never silently resolved; there is no merged status field and no live passthrough
Reference-list audits (up to 500 identifiers) returned as sealed receipts, recomputable against the snapshot they were run on (audit_verify: MATCH or DIVERGES naming the first divergent field)
Drift between two snapshots sealed as an artefact: verdict changes, new events, new divergences

Problems it addresses

I need to know whether a paper my agent cited was retracted, corrected, or flagged — with the notice provenance sealed, not a live search result
Two sources disagree about a paper's disposition and I need the disagreement preserved as data, not silently resolved
I need a reference-list audit receipt I can recompute later against the exact snapshot it ran on

Not tested

Live/production signing — receipts and snapshot are FIXTURE_SIGNED (house fixture HMAC key, disclosed in the seal block); no live claim attaches until a live signer decision (spec O3) is taken
Live source ingest — answers serve from the sealed snapshot only; no live passthrough exists or was tested

Evaluation-intake listing

This listing records the tool's place in the Bazaar's evaluation and monitoring pipeline, with the evidence gathered so far printed above — verdict, scope, and not-tested items included. It is not sold on this site, and its presence in the catalog is not a claim beyond that evidence. The service behind every verdict is the bench: what a bench run buys →
