Rust workspace serving a Google/Microsoft-Authenticator-style web UI, with
each account's rotating code mirrored into Discord as a message that
rewrites itself in place as the code rolls.
The live mechanism is webhook message editing: POST ?wait=true returns the
message id, PATCH .../messages/{id} rewrites it thereafter. Two approaches
were evaluated and rejected — an externally-hosted image URL is cached by
Discord's media proxy and, worse, must be anonymously reachable, which would
publish live codes on an unauthenticated endpoint; and an animated countdown
drifts out of phase because playback starts at decode time, not on a wall
clock. The countdown instead uses Discord's <t:unix:R> markup, which the
client re-renders every second for free.
Codes are also sent as text in a fenced block so they stay copyable, with
the grouped, readable form on a rendered WebP tile.
- core: RFC 6238 TOTP over HMAC, lenient otpauth:// parsing (issuer conflicts
and non-canonical base32 both occur in the wild), XChaCha20-Poly1305 vault,
Argon2id admin auth
- discord: webhook client with a serialising rate limiter (~2 req/s) so
globally-aligned rollovers don't burst, and error classification that
distinguishes a deleted message (repost) from a dead webhook (stop)
- render: SVG -> WebP tiles via resvg with embedded JetBrains Mono
- http-api: axum, session auth, QR decode with a rescale/contrast/rotation
retry ladder
- webui: offline vanilla JS, Beautiful UI design language, light and dark
Ships as a 27 MB Alpine image (about 8 MB to pull); the binary is fully static musl with no
OpenSSL and no C dependencies, cross-compiled via cargo-zigbuild so building
linux/amd64 on Apple Silicon needs no QEMU.
101 tests, including the RFC 6238 vectors, QR round-trips, and the live push
cycle exercised against a mock Discord.
