Bugfix (scgbckbone, 3 Aug 2026) detecting the STM32 RNG status error flags, retrying safely and failing closed. Named by Coinkite's 4 Aug 2026 notice as the fix for the post-hotfix TRNG fault behind the bricking reports.
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 .
This post is held twice: here, with this project's own note on why it matters, and again as part of the conversation captured at , which is polled for changes. Both copies are the same post; neither is a separate event.
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 the addresses of people who published nothing themselves. Capture times and reviewed change summaries remain available below.

1 presentation-noise difference. Sidebar, ticker and other page chrome churn that our review classified as not being a change to what the source says.
- +5 -3 Only GitHub header chrome changed. The 'Sign in' and 'Appearance settings' labels split onto separate lines, and the search prompt changed from 'Type / to search' to 'Search/'.
The excerpts and plain unified diffs above show the text this project held and how it changed. 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.
