chrome.runtime.sendMessage serializes with a JSON-like algorithm that drops
ArrayBuffer/TypedArray payloads — they arrive as empty objects, so a carrier
JPEG reached the service worker as 0 bytes and failed with the opaque WASM
error "no SOF marker found in JPEG". This broke extension vault creation.
- shared/message-binary.ts: encodeBinary/decodeBinary deep-walk a message tree
and base64-envelope every binary buffer so it survives the channel (chunked
base64 to avoid stack overflow on multi-MB buffers); plain number[] untouched.
- Wire encode/decode at all four message boundaries: popup, service-worker
onMessage listener (decode request, encode response), setup swSend, vault
postToServiceWorker.
- handleCreateVault: magic-byte guard classifies empty / non-JPEG carriers into
actionable errors (carrier_image_empty / carrier_image_not_jpeg) instead of
the opaque WASM error; error-copy.ts adds user-facing text; setup errors now
route through lookupErrorCopy.
- router SETUP_ALLOWED: add create_vault / attach_vault / generate_recovery_qr —
the Phase-3 setup wizard sends these from the setup page and they were being
rejected as unauthorized_sender.
- Tests: message-binary round-trip suite (7) + carrier-guard (2) + setup
allowlist (3). 435/435 vitest, build:all clean.

DEV-C P2: expiry cleared manifest but left the cached git-host client.
The initializer rebuilds gitHost on demand, so clearing here is safe.
No new test: index.ts has top-level chrome.* side effects that make it
expensive to import in a unit test, and the change is a one-liner state
mutation in an inline callback. Manually verified by tracing call sites.

DEV-C P2: an active autofiller never opens the popup, so under the old
rule it got force-locked despite continuous use. Inverts the rule:
reset on all messages except a documented exclusion set (only
get_autofill_candidates today).

Implements a service-worker-side session timer that locks the vault
after a configurable period of inactivity (default 15 min). Supports
two modes: 'inactivity' (timer-based) and 'every_time' (no timer).
Config persists via chrome.storage.local and is exposed through
get_session_config / update_session_config popup messages.

Bug: setup tab's zxcvbn meter silently stayed at score=-1 because the
router's isSetup exception only allowed save_setup, so rate_passphrase
got unauthorized_sender. Result: the "create vault" button stayed
disabled forever even with a strong passphrase.
Fix: add a narrow SETUP_ALLOWED set containing save_setup,
rate_passphrase, and is_unlocked (step-4 extension detection). Reject
everything else from the setup tab. Also clean up setup.ts's unlock
call — it was passing the raw 32-byte imageSecret where JPEG bytes with
embedded secret are required; the Rust-side unlock calls imgsecret::
extract internally.
Diagnostic logging across the message path so the next silent failure
speaks up:
- [relicario setup] staged logs through vault-init; console.error
with the failure stage name in the UI banner.
- [relicario setup] rate_passphrase lastError / rejected / threw
branches each log their own warning.
- [relicario router] console.warn on unauthorized_sender (with sender
classification) and unknown_message_type.
- [relicario sw] first-message wasm init announced; per-message
non-ok result logged; thrown errors console.error'd.
Tests: +3 setup-allowlist tests (rate_passphrase accepted, is_unlocked
accepted, fill_credentials + unlock rejected). 55/55 green.

Non-functional tightening flagged in the slice-3 code review:
- session.ts: document future multi-vault refactor (β+) so the module-
scope singleton is explicitly "deliberately simple," not an oversight.
- vault.ts: move findByHostname doc comment above the function; note
α's intentionally-coarse hostname match (no www-stripping, no
public-suffix matching) and that tighter matching is a β/γ concern.
- index.ts: expand the passphrase scope-clearing comment to make
the theatre explicit rather than leaving it looking like real defense.
- index.ts: TODO(slice-4) marker on delete_item's non-atomic two-write
path — consider manifest-first ordering or retry/rollback at router-
split time.
- index.ts: cross-reference comment on itemToManifestEntry pointing at
the Rust-side ManifestEntry::from_item derivation it must mirror.
No behavior change; build still compiles with 2 bundle-size warnings.

Chrome MV3 service workers do not support dynamic import().
Switch to static import of the wasm-pack JS glue and use
initSync() with fetch() to load the WASM binary at runtime.

- Fix .idfoto/ prefix for salt and params.json in vault.ts
- Cache TOTP secrets by entry ID to avoid re-fetching every second
- Fix keyboard navigation to use filtered entries, not unfiltered
- Add window.close() on Escape from entry list

Main entry point that loads WASM via dynamic import, manages vault state
(master key, manifest, git host), and handles all message types from
popup and content scripts.
