A freeq client in jolt, as glimmer components on Vidya   1
The last of the Clojure   3A **[freeq](https://github.com/codegod100/freeq)** client written in **Nim**,
4painted by Flutter. Nim owns the state, the screens, the IRC connection and
5the message signing; Flutter is a renderer over the widget tree it emits.

The last of the Clojure   31There were two other clients here. `src/` was jolt with a libcosmic window and
32a terminal; `common/` and `flutter/src/` were ClojureDart, compiled for
33Android, Linux and the web. Both are gone. The APK and the web target went with
34the second: a browser has no `dart:ffi`, so the web needs the core compiled to
35wasm rather than ClojureDart restored.

Sign in with a Bluesky identity   67
Sign in with Bluesky OAuth, through freeq's broker   68**Bluesky** (OAuth, the default way in) follows sleek's flow: frq binds a
69loopback port, puts it in `return_to`, and opens
70`auth.freeq.at/auth/login?handle=…`. The broker runs the OAuth dance with the
71PDS and redirects back to that port with the handoff in the URL *fragment*, so
72it never reaches a server as a query string. The page frq serves there has one
73job: POST the fragment back to itself. What comes back is a single-use SASL
74`web-token` and a durable `broker_token`; later connections mint a fresh token
75from the durable one at `/session` and skip the browser.
Sign in with a Bluesky identity   76
Remember an OAuth sign-in across restarts   77The durable token is saved to `$XDG_CONFIG_HOME/frq/session.edn` (mode 600) so
Connect on launch when an account is remembered   78a restart resumes without one, along with the handle and nick it belongs to —
79and it connects on its own at launch when one is there.
Remember an OAuth sign-in across restarts   80The web-token beside it is single-use and deliberately not saved. A token the
81broker no longer honours is dropped — from disk and memory — and the browser
82flow runs once more, rather than failing the same way on every Connect.
Sign in with Bluesky OAuth, through freeq's broker   84**App password** signs in without a browser, straight to the user's own PDS:
85`resolveHandle` → DID → PDS from the DID document → `createSession`. The
86password goes to that PDS and nowhere else, is never written to disk, and is
87dropped once the session exists.
Sign in with a Bluesky identity   88
Sign in with Bluesky OAuth, through freeq's broker   89Either way freeq sees only a token. The SASL mechanism is
90`ATPROTO-CHALLENGE` in both cases — `method: "web-token"`, which the server
91resolves through its own token store, or `method: "pds-session"` with the
92server's nonce echoed back so the token cannot be replayed elsewhere.
94A refused sign-in is reported and the connection carries on as a guest.

The last of the Clojure   100There were three, and losing two is the cost of the port rather than an
101accident. **The web** needs the core compiled to wasm — a browser has no
102`dart:ffi`, so there is no way for Dart to call a native library there, and
103that was true of this design from the first day. **Android** needs
104`libfrqcore.so` cross-compiled for its ABIs; `dart:ffi` works there, so this
105is a build problem rather than a design one.
