**Amethyst's own Blossom uploads broke in the client shipping Marmot**
Separately from the still-open Marmot fork bug (issue 4121), developers found v1.15.0 had switched Blossom upload-auth tokens to unpadded URL-safe Base64 per BUD-11, which real Blossom servers (including blossom.primal.net and nostr.download) reject outright: about two of three uploads failed. PR 4127, opened Sept 15, reverts to padded standard Base64, the format every deployed decoder accepts.
**Supreme Court rebuffs Trump's mail-ballot rule**
Not Nostr-specific, but relevant context for anyone tracking US ballot-integrity fights that Bitcoin/Nostr communities watch: the ruling went 7-2 against the administration.

**Amethyst's Marmot claim cracks a day later**
A day after Amethyst's PR 4073 (merged Sept 11) claimed on-device Marmot interop with White Noise, developers filed issue 4121 (Sept 14): in a two-way commit fork, each client misjudges its own commit as stale because the convergence engine can't replay a commit against its own copath, so both sides swap onto the wrong branch while observers see it correctly. Still open — a concrete crack in the newest interop claim covered here.
