# TASK METADATA

- **Target Files:** `ui/components/PasskeysPage.tsx`,
  `ui/components/RegisterPage.tsx`, `ui/components/auth/PasskeyTable.tsx`,
  `ui/components/auth/WebAuthnScript.tsx`,
  `ui/public/ui/utils/bip39_wordlist.ts`, `ui/utils/bip39_wordlist.ts`,
  `ui/ui_scripts.test.ts`
- **Core Objective:** Phase 3 (WebAuthn Scripts & Asset Deduplication): Extract
  shared WebAuthn client ceremony helper scripts into
  `ui/components/auth/WebAuthnScript.tsx`, modularize `PasskeysPage.tsx`, and
  delete the duplicate 2,051-line `ui/public/ui/utils/bip39_wordlist.ts` asset.
- **Dependencies:**
  `tasks/new/2026-0825.01.jul.story.arch.ui-decomposition-roadmap-2300.md`
- **Additional Important Notes:** Strictly 100% pure Hono SSR JSX. Preserve
  WebAuthn challenge/verify ceremonies, passkey deletion, and verify all
  wordlist imports point to `ui/utils/bip39_wordlist.ts`.

---

### 2. Architectural Considerations & Risks

- **Risks:**
  - Broken WebAuthn registration/login ceremony if base64url or credential
    creation helpers are altered.
  - Broken imports if files still reference the deleted
    `ui/public/ui/utils/bip39_wordlist.ts`.
- **Mitigation:**
  - Verify with `deno task check` and `deno test --allow-all`.

### 3. Proposed Implementation

1. **Extract WebAuthn Components & Scripts (`ui/components/auth/`):**
   - `PasskeyTable.tsx`: Passkeys list table and mobile deck rendering.
   - `WebAuthnScript.tsx`: SSR JSX script component containing shared base64url
     converters, biometric ceremony triggers, and challenge handlers.

2. **Deduplicate Wordlist Asset:**
   - Delete `ui/public/ui/utils/bip39_wordlist.ts`.
   - Update any import statements to point directly to
     `ui/utils/bip39_wordlist.ts`.

3. **Quality Gates & Validation:**
   - Run `deno fmt`, `deno task lint`, `deno task check`.
   - Run `deno test --allow-all` (all 58 tests must pass).
