"""Tests for the vault-backed password-blind browser autofill feature.

Covers:
- VaultStore: encrypt/decrypt round-trip, file perms, identifier-as-metadata
  (login secret payload is password-only)
- login-control classifier: scoring + new-password/one-time-code exclusion,
  password-only fill selection
- origin-binding refusal (pre-check + in-script TOCTOU assert)
- fail-closed secret eval (no argv fallback)
- vault-value redaction registry (browser_cdp read-back regression)
- tool gating: check_fn False when the vault is empty
