Open incident-response proposal to absorb a bytes-like seed into all Yasmarang state words. Companion to Coldcard/firmware PR #691.
Every check is recorded, including checks that found no text change. A detected edit is therefore bounded between two checks. The publisher's exact save time is not observable from this record. Last checked 2 Aug 2026, 00:58 UTC.
Snapshot and diff bodies for this chain monitor are held in the local evidence archive but withheld from the public site because they can contain victim addresses. Integrity hashes, capture times and reviewed change summaries remain available below.

The inline cross-reference to Coldcard/firmware#691 changed from Open to Draft, reflecting a real state change on that pull request rather than rendering variance. Nothing else moved: no discussion, review or patch text on this pull request changed. The underlying state change is captured directly on coldcard-firmware-pr-691 at 20260801T174121Z, so this entry is the same event seen from the linked repository.
Recovered from the Internet Archive rather than captured by this project. The row records that third-party provenance separately from captures made by this project.

Two contributors reviewed the reseed change, the author pushed a second commit rejecting a zero-length seed and documenting a roughly 72-bit state ceiling, a reviewer argued for removing Yasmarang entirely and announced a competing pull request, and the author closed this one in favour of #61.

Each copy above is identified by the SHA-256 of its extracted text, shown beside it, and the diffs are plain unified diffs. To verify a quotation, compare it against the page itself or against the Internet Archive's copies, which are independent of this project.
Complete captures are held offline rather than mirrored here, so this page shows diffs and excerpts. If a quotation is ever disputed, the full copy can be produced. Ask.
The SHA-256 prefixes above identify each held copy without turning this page into a mirror of somebody else's post. Compare a quotation against the original. If the post has since been edited or deleted, ask and the held copy can be produced.
