The PDS access JWT expires after 1 hour; the refresh JWT lasts
90 days. Before this commit, every action (post, like, follow,
post create, etc.) started failing with the user's first action
after the hour mark, forcing a manual re-login. Now safeInvoke
catches the TokenInvalid / ExpiredSignature response, calls the
'auth_refresh' Tauri command to mint a fresh access JWT, then
retries the original call exactly once.
Concurrent 401s during a refresh-window share a single in-flight
'auth_refresh' call via the pendingRefresh promise — without it,
a single expired JWT would trigger N parallel refreshes on the
Rust side, which would issue N new refresh JWTs and silently drop
all but the last one on save().
The refresh() method is exposed on the session store so callers
outside safeInvoke (the explicit 'session.refreshed' toast etc.)
can also trigger it. The auth_* commands themselves are
excluded from the retry path so a bad login doesn't loop into
'refresh → 401 → refresh' forever.
Wire shape match: the auth_refresh command returns AccountSession
{ did, handle, access_jwt, refresh_jwt } which matches our
Session type, so the store can 'set(s)' directly without a
field-by-field copy.

Status
| Phase | Stand |
|---|---|
| 0 Foundation, Workspace, Migrations, Lexicon, Crypto | ✅ done |
| 1 Identity (PLC-Ops vollständig signieren) | ⏳ TODO (JWT-PEM fehlt) |
| 2 MST + Repo (Spec-konforme CBOR-Encoding) | ⏳ Skelett steht |
| 3 PDS-Server (com.atproto.* XRPC) | ⏳ Skelett, nur Healthz |
| 4 AppView-Foundation (Jetstream-Index) | ⏳ Skelett |
| 5 AppView-REST-API | ⏳ Stubs |
| 6 Tauri-UI-Logik an Backend koppeln | ⏳ Stubs |
| 7 Polish (Tray, Notifications, Auto-Update) | ⏳ |
Tests
running 12 tests (at-crypto)
test result: ok. 11 passed; 0 failed; 1 ignored
running 3 tests (at-lexicon)
test result: ok. 3 passed; 0 failed
running 2 tests (at-shared)
test result: ok. 2 passed; 0 failed
running 2 tests (at-repo)
test result: ok. 2 passed; 0 failed
Der eine ignored Test (jwt::issue_and_verify) braucht noch einen ASN.1-SEC1-PEM-Encoder — geplant für Phase 1.
Design
