Broad incident-response PR. On 1 Aug the maintainer called the diff too large and the author offered a three-PR split.

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.

  1. source content difference between 1 Aug 2026, 03:50 UTC and 1 Aug 2026, 16:08 UTC Current source content +20 -2

    The pull request was closed by its author in favour of a three-pull-request stack (#62, #63 and #64) described as summing to a byte-identical tree, with a suggested review order and an offer to reopen.

    +Per your feedback that the diff was too big, I've split this into a stack of three PRs that sum to exactly this branch (byte-identical tree):
    +add HMAC_DRBG (SP 800-90A 10.1.2, SHA-256), verified against NIST CAVP vectors #62 — the HMAC_DRBG core + NIST CAVP test harness (pure addition, self-verifying, no behavior change to any build)
    +add entropy health rule as a pure, deterministically tested module #63 — the entropy health rule + its deterministic tests (pure addition)
    +random: fail-closed entropy backends; all output via HMAC_DRBG #64 — the random.c rework that composes them, with compile-gate regression tests and README (the part that fixes the advisory)
    +Suggested review order is #62 → #63 → #64 ; each is small on its own, and #63/#64 will show only their own commits once their predecessors merge. Closing this one in favor of the stack — happy to reopen if you'd rather review it whole.
    +All reactions

    +diff too big
    +I'd be happy to split into a 3-PR stack: two independent, self-verifying additions (DRBG+CAVP, health rule) and then the random.c rework as a much smaller final diff.

How to check this yourself

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.
