Bluesky Protocol Services
Bluesky's public infrastructure layer for ATProto developers, including Jetstream v2 network replay, typed SDKs, and the Bluesky HTTP reference.
malachite gains a polish migration subtool
A new -m polish mode (and matching web wizard card) backfills legacy fm.teal.alpha.feed.play scrobbles into production fm.teal.feed.play, preserving rkeys, then removes the legacy copies after each backfill succeeds. The migration logic is shared through croft-click-core.
New project — keepsake, a text RPG whose save file is your AT Protocol DID
A C++23 text adventure where signing in makes your own PDS the save file — character sheet, quest progress, verifiable achievements, and a firehose-fed shared world, built in under a day.
MetalBear gets a local dev instance and fixes its own did:web self-resolution
Standing up a real localhost-only PDS surfaced two bugs -- did:web never resolved its own DID document when the DID encoded a port, and account creation had no way to avoid minting a real did:plc on the live PLC directory. Both fixed. 0.39.0 to 0.39.1.
wolfram's server goes multithreaded, and the Wii build gets un-broken
The XRPC server picked up a real thread pool and an async client SDK, rate limiting and per-route auth policies got finished off, and a spliced function signature that silently broke the Wii/Wii U cross-build for a week got found and fixed.
Inkwell reaches standard.horse content parity and ships on AltStore
Since launch, inkwell added pub.leaflet.comment support, all 18 Leaflet block types, Constellation-backed cross-repo discovery, and fixed PDS resolution for DIDs — then shipped a real AltStore sideloading source with a signed IPA.
MetalBear's frontend becomes a self-service console, and CI starts testing the containers it ships
The frontend grew from bare login/OAuth-consent pages into a full account console -- passkeys, password/email/handle changes, data export, guided migration, an admin dashboard -- while a separate thread found the shipped Docker image had never actually been able to start, and fixed the release pipeline that let that ship three times. 0.7.0 to 0.38.2.
MetalBear hardens OAuth, session scopes, and identity against the reference PDS
An unauthenticated login_hint could mint an OAuth code for any account, app passwords and full-access OAuth grants could reach account-deletion and email-change endpoints, and DPoP was optional everywhere it mattered -- all closed, alongside a run of PLC identity bugs and a new WebAuthn/passkey login path. 0.7.0 to 0.38.2.
wolfram closes a DPoP sender-constraint bypass and hardens identity resolution
A DPoP-bound OAuth token could be silently rebound to an attacker's key when it had no cnf.jkt at issuance; fixed alongside a fail-open handle-verification bug, response-body leaks on every failed DID fetch, unbounded network waits, and new PLC/DID APIs.
wolfram's CLI becomes a real AT Protocol client, and the agent layer sheds its stubs
wolf grew from a ~45-command demo into a full-coverage client with 14 focused modules, gained a PDSls-style browse/identity/plc-log trio, and several agent-level "honest stubs" got real implementations.
MetalBear closes its reference-parity gap on server, admin, and repo writes
A sustained audit against the reference PDS fixed admin field gaps, repo write-path error codes, blob and repo store concurrency bugs, and split a sprawling server.c into domain-scoped files. 0.7.0 to 0.39.0.

pkgs adds ListenBrainz support and consolidates its tools onto croft-click-core
Malachite and its web frontend gained a ListenBrainz import mode, tourmaline switched to CAR-export scrobble fetching and hardened its server routes, pds-landing got a live activity feed, and every write-capable tool now shares one ~/.ewanc26 state directory.
Artist app diary (2): how to stay sustainable with community building and financial funding

I Totally Misunderstood ATProto
I thought I knew what AT Protocol was about. It was for Bluesky and Bluesky-like sites and maybe auth. I wasn't entirely wrong but I was also way off the mark.
