Three bugs fixed:
1. Phase 30 (auth.ts): After SRP login the encrypted_key_set was returned
from the server but the vault key and RSA private key were never unwrapped
with the AUK. keyStore.getVaultKey() was always null, causing Tier 1
config-backup diffs to crash with a TypeError.
Fix: unwrap vault key and private key using crypto.subtle.unwrapKey after
successful SRP verification. Non-fatal: warns to console if decryption
fails so login always succeeds.
2. Token refresh (auth.py): The /refresh endpoint required refresh_token in
the request body, but the frontend never stored or sent it. After the 15-
minute access token TTL, all authenticated API calls would fail silently
because the interceptor sent an empty body and received 422 (not 401),
so the retry loop never fired.
Fix: login/srpVerify now set an httpOnly refresh_token cookie scoped to
/api/auth/refresh. The refresh endpoint now accepts the token from either
cookie (preferred) or body (legacy). Logout clears both cookies.
RefreshRequest.refresh_token is now Optional to allow empty-body calls.
3. Silent token rotation: the /refresh endpoint now also rotates the refresh
token cookie on each use (issues a fresh token), reducing the window for
stolen refresh token replay.
