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.
