The 0.18.1 fix relied on an existing-device + present-stronghold-key match.
That fails for users who:
- had multiple device registrations and only retain the latest device's
private key in the local vault
- had a vault wipe / fresh OS install at some point
- have device rows that vanished server-side but keys still locally
Migration now scans conversation_keys for distinct un-migrated
recipient_device_ids visible to the user (RLS-filtered) and probes the
stronghold for each, regardless of whether the server still lists that
device. Result struct surfaces attempted/migrated/noKey/decryptFail/rpcFail
counters; SecurityCenter shows them via a new "Migration erneut ausführen"
button so users can self-diagnose without DevTools.
Also adds [crypto-migration] console.info breadcrumbs at every decision
point so a single F12 shows what happened.
PostgREST translates .eq('col', null) to `col = NULL` which is always false
in SQL. The migration silently returned zero rows -> setupNewUserIdentity
fired but re-wrapped nothing -> users could set a PIN but every send threw
'Awaiting key'. Switching to .is('col', null) emits `col IS NULL` and the
migration finally finds its work.
Also makes the migration trigger idempotent and re-fires it on:
- every successful loadOrUnlockUserKey
- AuthContext startup when the user-key is already cached
so users stuck on 0.18.0 auto-recover the moment they install 0.18.1.
PinInput: focused + active-slot now show a brand-coloured ring, glow, and
a blinking caret so users see where the next keystroke lands.
