The diff adds no content claims, no citations (verification section confirms none), and publishes no confidential material: the correspondence files stay out of the tree and the tombstone README still states that the raw email is not stored and is retained privately by the editor. The history.yaml addition is a genuine append at the end of the file, and DECISIONS.md is appended without deleting or rewriting the prior 2026-08-26 removal entry, so the earlier admission of the §3.15 breach remains visible in full. The permission record is honest about its chain of custody — granted by Villarroel to the founder on 2026-08-26, relayed by him to the maintainer the same day, grant correspondence held by the founder — and it attributes the relay rather than dressing hearsay up as a first-hand record; contact by the founder is now publicly logged, consistent with the no-silent-contact rule. My only reservation is that the 'by what channel' element of §3.15's permission standard is thin ('told the founder'), but nothing is published, quoted, or cited on the strength of this permission, so the imprecision is not consequential. Downgrading the history rewrite from urgent to optional does not weaken a §3.15 check: the rewrite is a remediation reserved to the founder, it remains available, and the entry candidly states the remaining third-party residue (cc address, research/ captures) that still argues for it. No AGENTS.md edit is present.

The change records, in an append-only way, that permission for including Villarroel’s email was granted after its removal, and explicitly notes who granted it, when, by what channel/custody — aligning with §3.15’s requirement that permission be treated like any other provenance. It does not reintroduce the private correspondence or any confidential content into the repository; instead it keeps the files out of the tree specifically because of third-party personal data and remarks, which is consistent with the prohibition on publishing material supplied in confidence. No prior assessments, claims, or sources are silently altered or weakened; instead, the history and tombstone README are updated to clarify the status of the old commits and the now-optional nature of a history rewrite. No citations, locators, or provenance details are fabricated; the update concerns internal process history rather than external literature, and the citation checker confirms no new identifiers were added. AGENTS.md is not modified, so there is no attempt to alter the constitutional rules themselves. Overall, the diff strengthens transparency about consent and repository hygiene without weakening any epistemic checks, so it complies with the constitution.

The PR adheres strictly to the §3.15 protocol for recording permission to retain previously confidential material. It accurately documents who granted the permission (Villarroel to the founder), the date (2026-08-26), the channel, and the custody of the grant (held by the founder). Furthermore, the PR correctly maintains the exclusion of the actual files from the tree, recognizing that the newly acquired permission does not cover the third-party personal data contained within the correspondence. No rules are weakened, and no citations are fabricated.

The diff only appends a housekeeping history entry, updates the tombstone README, and adds a DECISIONS.md note; it does not restore, quote, paraphrase, or cite the removed correspondence, and it does not edit AGENTS.md. The permission record states who granted it (Villarroel to the founder), the date (2026-08-26), the relay channel, and custody (grant correspondence held by the founder), which is the §3.15 provenance shape, while keeping the files out because third-party addresses and remarks still lack permission. Downgrading the history rewrite from urgent to optional is a process judgment about residue in old commits, not a weakening or reclassification of the checks themselves. No citation identifiers were added, omitted-file risk is none, and there is no positive internal evidence of fabricated locators or provenance.

This PR does exactly what §3.15's permission standard requires: it records the grant with who (Villarroel to the founder), when (2026-08-26), custody (grant correspondence held by the founder), and the relay path, in append-only history.yaml and DECISIONS.md entries plus an updated tombstone. Critically, it publishes nothing confidential — the correspondence files stay out of the tree, explicitly because a third party's cc address and remarks about colleagues are not covered by her permission, and nothing in the ledger cites the email. The downgrade of the history rewrite from urgent to optional is reasoned, not check-weakening: the rewrite remains available and reserved to the founder's authorization, and the remaining residue (third-party captures, cc address in old blobs) is honestly disclosed. The permission claim itself is unverifiable by the panel but internally consistent (dates align with the same-day removal) and shows no positive evidence of fabrication, so temporal humility applies. Updating the tombstone to reflect the recorded permission is a provenance correction, not a silent change to a published judgment — git preserves the prior text. The edit to DECISIONS.md is an append to an append-only log, and AGENTS.md is untouched. Channel of the grant is only implicit ('correspondence recording the grant'), an ordinary imperfection rather than a violation.
