Two spine infra items (feature-ranking #1, part of the migration prereq):
- migrations.go: PRAGMA user_version runner, empty (no-op) migration slice,
one tx per step, fail-closed. Mechanism in place before any real schema
change needs it.
- crypt.go: file-level at-rest encryption. On-disk file is always AES-256-GCM
ciphertext; decrypted to a tmpfs working copy modernc sqlite operates on;
re-encrypted atomically on Close, plaintext wiped, key zeroed. Pure stdlib,
CGO stays off. Fails closed on wrong key/tamper, never falls back to
plaintext. Key is a 32-byte seam (config db_key_b64/db_key_env today; the
passkey-derived L3 cold-start key plugs into the same seam later).
Chosen over cgo SQLCipher (would force libsqlcipher + CGO across the project)
and over the ncruces page-level VFS (swaps the driver project-wide); noted as
the upgrade path in a ponytail: comment. Threat model is disk-at-rest only.

Completes the three in-flight open items and fixes the away-fallthrough bug.
Item 7 — passkey step-up (WebAuthn):
- internal/webauthn: ES256/P-256 register + assert with real ecdsa signature
verification, minimal CBOR/COSE decode, PasskeySession (L2→L3 on assert,
decays after TTL). Drop the RS256 offer we can't verify (register-ok/
assert-fail trap). Verify rpIdHash + UP/UV flags in FinishAssertion — UV is
the step-up gesture. Round-trip test with negative cases (tampered sig,
missing UV, wrong origin).
- cmd/mavweb: /auth/passkey enroll+assert page (the only surface that can do
a WebAuthn gesture) + the four begin/finish endpoints. Without this the
daemon's PasskeySession swap leaves /tools enable permanently blocked.
- daemon wires PasskeySession as the auth Session + srv.StepUp; policy gates
MethodAssertStepUp at AuthRead.
Item 5 — tools page: DisableTool through store/ipc/client/wire; /tools grows a
disable action and a link to the passkey page. Lifecycle test.
Item 6 — note RAG: PhraseQuery on the phraser (LLM-composed answer over top-k
notes, raw-notes fallback); IntentQuery routes through it. Stub returns a
deterministic summary.
Item 2 — away-fallthrough: on ErrVoiceNoSession the dispatcher now reroutes
through the AWAY table (sev3→ntfy, sev4→telegram-repeat-til-ack, sev≤2→drop)
instead of silently dropping / mis-routing to the present-list remainder.
Covers DispatchNudge + DispatchReminder. 4 tests.
Also: re-add ProposeTool to CoreAPI (dropped in a comment rewrite), fix
missing imports + a duplicate block left mid-edit, drop dead AssertStepUpFunc,
gitignore /mavcaldav.

worker/server.go: dispatch now receives a per-connection context instead of
context.Background(), so handler cancellation propagates on conn close.
voice/server.go: same — per-conn context fed through safeDispatch into
HandlePushToTalk instead of context.Background().
store/reminders.go: propagate LastInsertId error.
store/nudges.go: propagate LastInsertId and RowsAffected errors.
store/tools.go: propagate RowsAffected error.
config/config.go: applyDefaults now respects StateDir when set, using it as
the base for empty DBPath/SocketPath instead of silently ignoring it.
phraser/llmphraser.go: close stderr pipe fd when cmd.Start() fails.
