That inflates the password count, so82+   `isLoginForm(detectLoginFields())` is `false` for a normal single-password83+   login — the page is recognised as fillable via the `isSignupForm` branch of84+   `isAnyCredentialForm` instead. Detect tests therefore assert detection by85+   *membership* and the page gate via `isAnyCredentialForm`, and test the86+   login-vs-signup classifier on clean, hand-built arrays (matching the committed87+   `detect.test.ts`). It also misses shadow-DOM inputs that are *direct* children88+   of a shadow root (only those nested under an element are collected).89+2. **Closed shadow roots.** `showAutofillSelector`, `showTOTPSelector`,90+   `showCardSelector`, and `save.ts`'s banner all mount `attachShadow({ mode:91+   "closed" })`. Their interiors (entry rows, search box, keyboard nav, TOTP92+   chip, Save/Update buttons, homograph warning) are unreachable from any93+   external script. Unit tests assert only mount/dismiss + outbound messages;94+   the interiors are covered by the e2e through effects. **Recommendation:** add95+   a test-only "open shadow in `import.meta.env.MODE==='test'`" seam if richer96+   unit coverage of the selector interior is wanted.97+3. **`wasAlreadyFilled` page-grace is NOT form-scoped** (brief T-D10 assumed it98+   was). For `PAGE_FILL_GRACE_MS` (3 s) it suppresses *every* field; after the99+   window, only the filled form stays locked (`filledForms` is permanent). Tests100+   pin the actual behavior.101+4. **`fillFields` returns `void`** (brief T-FL12 assumed it returns the filled102+   set). Fill-success tracking is the caller's job (`recordFillSuccess`).103+5. **`detectPasswordPolicy` ignores a `minlength` attribute** (brief T-PO01); it104+   reads `maxLength`, the `pattern`, and nearby text. It inspects only the first105+   password field, so "most restrictive across fields" (T-PO06) is not106+   implemented.107+6. **No `DISMISS_AUTOFILL` / `FILL_AND_SUBMIT` messages** in index.ts's listener108+   (brief T-M06/T-M07). The search-palette path is `SUMMON_AUTOFILL` with no109+   form (T-M08 ≡ T-M02 here).110+7. **PCH-01-025 CSS.escape:** jsdom's selector engine *throws* on `CSS.escape`'s111+   output, so the label-resolution benefit is only observable in the e2e. The112+   unit tests pin the resilience invariant (a hostile id never aborts detection;113+   the embedded-quote case fails if the try/catch is removed).114+8. **Benign teardown log.** Importing the real `index.ts` registers a url-watcher115+   `MutationObserver`; its callback can log `location is not defined` once during116+   jsdom teardown. Exit code is 0 and no test fails.
