The change is confined to pipeline logic, one test, and a dated DECISIONS entry; it edits no content records and adds no citations (verification found none). Functionally it distinguishes a quote miss against a stand-in text (open-access copy or arXiv PDF chosen by the fetch layer) from a miss in the cited document itself: the former is now rejected as *blocked* with an explicit route ("obtain the text of SRC-X as cited (URL) and re-run verify; the quotes were checked only against …"), the latter still fails. Either way the record does not enter the ledger, so no unverified quote is admitted and no §3.15 check is loosened or dodged — the honest labeling of what was actually checked is strengthened rather than weakened (§3.8, §3.9). The predicate `substituteCopy` keys on a typed flag set only at the two fetch sites that substitute a copy, explicitly refusing to infer stand-in status from the free-text `via` description, and the test pins that a supplied document and a Wayback snapshot of the cited page are not substitutes — so a direct document cannot escape failure. AGENTS.md is untouched; the DECISIONS line is stamped with date and channel for the founder direction, which §3.15 permits as operating record. No fabricated provenance is visible: the Łucejko 2018 / OpenAlex handle and arXiv path appear only as test fixtures and rationale, not as ledger citations.

The change does not admit a quotation that failed verification: it keeps the record blocked and gives a concrete route to obtain the cited text and rerun verification. The substitute status is set by typed provenance at the two fetch paths that deliberately retrieve a stand-in, while descriptive `via` text alone cannot downgrade a direct-document mismatch. Direct and supplied-document quote misses still fail, so the real-citation and exact-provenance checks are not weakened or dodged.

The change refines quote verification when checking against a substitute copy (such as an OpenAlex open-access repository or an arXiv full-text PDF read in place of an abstract page). Instead of marking the quote as flatly failed when not found in the stand-in text, it marks the record as blocked with an explicit route to inspect the cited primary document. Nothing is admitted or published without verification, preserving fail-closed admission and provenance rules while accurately distinguishing unverified substitute texts from fabricated quotes.

The diff only adjusts verify/fetch so a quote miss against a fetch-flagged substitute copy (OpenAlex OA or arXiv PDF stand-in) is blocked with an explicit route to obtain the cited text, while a miss in the document itself or a supplied document still fails. That is more honest verification labeling (§3.8/§3.15), not a loosened check: records still cannot pass on an unchecked substitute. The typed `substitute` flag (not the via string) drives the branch; tests cover both sides; DECISIONS.md records the founder direction; AGENTS.md and content/ are untouched.

This change does not weaken the quote-verification check — it makes its epistemics more accurate. Before and after, a quote that cannot be found verbatim in the cited document's own text still fails and cannot publish; what changes is only that a miss against a stand-in copy (an OpenAlex open-access copy or an arXiv PDF read for an abstract page) is classified as blocked-with-a-route rather than failed, and the record still cannot enter the ledger until the quotes are verified against the text as cited. That distinction — 'not found in a substitute copy' being unverified rather than false — is exactly the calibrated, honest-labeling behavior §3.8 and §3.13 demand, and no fabricated quote gains a new path to publication since acceptance still requires a verbatim match in the cited document itself. The substitute flag is set by typed fetch-layer logic rather than by parsing the free-text `via` description, with tests covering both directions, and the reasoning is documented in docs/DECISIONS.md. AGENTS.md is untouched, no citations are added, and the diff is complete with no omitted files, so there is nothing hidden that could hide a violation.
