# Relicario Extension 1C-β₂ (Custom Fields + Settings + Generator UI) Implementation Plan

> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.

**Goal:** Add custom-fields editing, a full vault-settings view, and an inline generator popover to the Relicario browser extension. Completes the β phase of Plan 1C.

**Architecture:** 5-slice bottom-up. Slice 1 adds read-only `Item.sections` rendering in every type-detail view via a new `fields.ts` helper. Slice 2 adds the collapsible "▸ custom sections & fields" disclosure + add/remove UI in every type form. Slice 3 wires new popup-only messages (`get_vault_settings` / `update_vault_settings`, plus `generate_passphrase` for BIP39) — landing BEFORE the popover so Slice 4's "save as default" action is fully functional the moment it ships. Slice 4 builds the generator popover and wires it to every "gen" button. Slice 5 builds the Settings screen, wires the ⚙ picker, and connects the popover to Settings via the save-as-default action.

**Tech Stack:** TypeScript (extension popup), Vitest + happy-dom, Bun (package manager). No Rust changes.

**Reference spec:** `docs/superpowers/specs/2026-04-22-relicario-extension-1c-beta2-design.md` (commit `62112f5`)

**Branch:** Create `feature/typed-items-1c-beta2` off `main` (β₁ merged at `81fbe13`, tag `plan-1c-beta1-complete`).

---

## Pre-flight

- [ ] **P1: Verify main is clean and tests are green**

```bash
cd /home/alee/Sources/relicario
git status
git checkout main && git pull
cargo test --workspace 2>&1 | grep "test result" | head -3
```

Expected: working tree clean, on `main`, all Rust tests pass (155 from β₁).

- [ ] **P2: Create the feature worktree**

```bash
cd /home/alee/Sources/relicario
git worktree add .worktrees/typed-items-1c-beta2 -b feature/typed-items-1c-beta2
cd .worktrees/typed-items-1c-beta2/extension
bun install
bun run test 2>&1 | grep -E "Tests|Test Files" | tail -3
```

Expected: 84 Vitest tests pass (β₁ baseline).

## Slice 1 — Custom-fields detail rendering

### Task 1: Add `renderSections` helper + tests

**Files:**
- Modify: `extension/src/popup/components/fields.ts`
- Create: `extension/src/popup/components/__tests__/sections-render.test.ts`
- Modify: `extension/src/popup/styles.css`

- [ ] **Step 1: Write the failing tests**

Create `extension/src/popup/components/__tests__/sections-render.test.ts`:

```ts
import { describe, expect, it } from 'vitest';
import { renderSections } from '../fields';
import type { Item } from '../../../shared/types';

function itemWithSections(sections: Item['sections']): Item {
  return {
    id: 'aaaaaaaaaaaaaaaa',
    title: 'test',
    type: 'login',
    tags: [], favorite: false,
    created: 0, modified: 0,
    core: { type: 'login' },
    sections,
    attachments: [],
    field_history: {},
  };
}

describe('renderSections', () => {
  it('returns empty string when item has no sections', () => {
    const html = renderSections(itemWithSections([]), 'login');
    expect(html).toBe('');
  });

  it('skips sections with zero fields', () => {
    const html = renderSections(itemWithSections([
      { name: 'empty', fields: [] },
    ]), 'login');
    expect(html).not.toContain('empty');
  });

  it('renders a named section header + field rows', () => {
    const html = renderSections(itemWithSections([
      {
        name: 'recovery codes',
        fields: [
          { id: 'f0000001', label: 'code 1', kind: 'text',
            value: { kind: 'text', value: 'abc-123' }, hidden_by_default: false },
        ],
      },
    ]), 'login');
    expect(html).toContain('recovery codes');
    expect(html).toContain('code 1');
    expect(html).toContain('abc-123');
  });

  it('renders concealed password fields with unique ids', () => {
    const html = renderSections(itemWithSections([
      {
        name: 'backup',
        fields: [
          { id: 'f0000002', label: 'pin', kind: 'password',
            value: { kind: 'password', value: 'hunter2' }, hidden_by_default: true },
        ],
      },
    ]), 'login');
    expect(html).toContain('data-field-id="login-s0-f0"');
    expect(html).toContain('data-revealed="false"');
    // Plaintext should be in data-field-value, not visible
    expect(html).not.toMatch(/>hunter2</);
  });

  it('renders anonymous section with separator not header', () => {
    const html = renderSections(itemWithSections([
      {
        fields: [
          { id: 'f0000003', label: 'extra', kind: 'text',
            value: { kind: 'text', value: 'note' }, hidden_by_default: false },
        ],
      },
    ]), 'login');
    expect(html).toContain('section-separator');
    expect(html).not.toContain('section-header');
  });

  it('silently skips unsupported field kinds', () => {
    const html = renderSections(itemWithSections([
      {
        fields: [
          { id: 'f0000004', label: 'link', kind: 'url' as any,
            value: { kind: 'url', value: 'https://example.com' } as any,
            hidden_by_default: false },
          { id: 'f0000005', label: 'note', kind: 'text',
            value: { kind: 'text', value: 'kept' }, hidden_by_default: false },
        ],
      },
    ]), 'login');
    expect(html).not.toContain('https://example.com');
    expect(html).toContain('kept');
  });

  it('renders concealed fields for the concealed kind too', () => {
    const html = renderSections(itemWithSections([
      {
        fields: [
          { id: 'f0000006', label: 'secret', kind: 'concealed',
            value: { kind: 'concealed', value: 'shhh' }, hidden_by_default: true },
        ],
      },
    ]), 'login');
    expect(html).toContain('data-field-id="login-s0-f0"');
    expect(html).toContain('secret');
    expect(html).not.toMatch(/>shhh</);
  });
});
```

- [ ] **Step 2: Run — tests fail (renderSections not exported)**

```bash
cd /home/alee/Sources/relicario/.worktrees/typed-items-1c-beta2/extension
bun run test src/popup/components/__tests__/sections-render.test.ts 2>&1 | tail -10
```

Expected: import error for `renderSections` from `../fields`.

- [ ] **Step 3: Add `renderSections` to `fields.ts`**

Append to `extension/src/popup/components/fields.ts` (after the existing exports):

```ts
import type { Item, Section } from '../../shared/types';

/// Render an Item's sections as read-only field rows. Each section with
/// ≥1 field emits a header (if named) or thin separator (if anonymous)
/// plus field rows via renderRow / renderConcealedRow. Sections with
/// 0 fields are skipped. Fields with unsupported kinds are silently
/// skipped (β₂ supports text, password, concealed only).
///
/// `idPrefix` uniquifies concealed-row IDs (`${idPrefix}-s{i}-f{j}`)
/// so multiple typed-item detail views rendered in sequence don't
/// collide on wireFieldHandlers lookups.
export function renderSections(item: Item, idPrefix: string): string {
  let out = '';
  item.sections.forEach((section, sIdx) => {
    const visibleFields = section.fields.filter(
      (f) => f.value.kind === 'text' || f.value.kind === 'password' || f.value.kind === 'concealed',
    );
    if (visibleFields.length === 0) return;

    if (section.name) {
      out += `<div class="section-header">${escapeHtml(section.name)}</div>`;
    } else {
      out += `<hr class="section-separator">`;
    }

    visibleFields.forEach((field, fIdx) => {
      if (field.value.kind === 'text') {
        out += renderRow({ label: field.label, value: field.value.value, copyable: true });
      } else {
        // password or concealed
        out += renderConcealedRow({
          id: `${idPrefix}-s${sIdx}-f${fIdx}`,
          label: field.label,
          value: field.value.value,
        });
      }
    });
  });
  return out;
}
```

- [ ] **Step 4: Add the supporting CSS**

Append to `extension/src/popup/styles.css`:

```css
/* --- custom-section rendering (β₂ slice 1) --- */
.section-header {
  margin-top: 14px;
  margin-bottom: 4px;
  padding-top: 10px;
  border-top: 1px solid #21262d;
  color: #8b949e;
  font-size: 10px;
  text-transform: uppercase;
  letter-spacing: 0.08em;
}
.section-separator {
  margin: 10px 0 4px;
  border: 0;
  border-top: 1px solid #21262d;
}
```

- [ ] **Step 5: Re-run tests — should pass**

```bash
cd extension && bun run test src/popup/components/__tests__/sections-render.test.ts 2>&1 | tail -10
```

Expected: 7 tests pass.

- [ ] **Step 6: Verify full test suite + build**

```bash
cd extension && bun run test 2>&1 | grep -E "Tests|Test Files" | tail -3
cd extension && bun run build 2>&1 | tail -3
```

Expected: 91 tests pass (84 baseline + 7 new); build clean.

- [ ] **Step 7: Commit**

```bash
cd /home/alee/Sources/relicario/.worktrees/typed-items-1c-beta2
git add extension/src/popup/components/fields.ts \
        extension/src/popup/components/__tests__/sections-render.test.ts \
        extension/src/popup/styles.css
git commit -m "feat(ext/popup): renderSections helper for custom-field detail rendering"
```

### Task 2: Integrate `renderSections` into all 6 type detail views

**Files:**
- Modify: `extension/src/popup/components/types/login.ts`
- Modify: `extension/src/popup/components/types/secure-note.ts`
- Modify: `extension/src/popup/components/types/identity.ts`
- Modify: `extension/src/popup/components/types/card.ts`
- Modify: `extension/src/popup/components/types/key.ts`
- Modify: `extension/src/popup/components/types/totp.ts`

- [ ] **Step 1: Add the import to each type module**

In each of the 6 files, find the existing `fields` import (something like `import { renderRow, renderConcealedRow, renderSignatureBlock, wireFieldHandlers } from '../fields';`) and add `renderSections` to it:

```ts
import {
  renderRow, renderConcealedRow, renderSignatureBlock,
  wireFieldHandlers, renderSections,
} from '../fields';
```

- [ ] **Step 2: Insert the `renderSections` call into each `renderDetail`**

In each type module's `renderDetail` function, the HTML template has a structure like:

```ts
app.innerHTML = `
  <div class="pad">
    ${/* signature block */}
    ${/* typed rows (renderRow / renderConcealedRow) */}
    <div class="form-actions" style="margin-top:14px;">
      <button class="btn" id="back-btn">back</button>
      ...
    </div>
  </div>
`;
```

Insert `${renderSections(item, '<type-slug>')}` immediately before the `<div class="form-actions">`:

- `login.ts`: `${renderSections(item, 'login')}` before form-actions.
- `secure-note.ts`: `${renderSections(item, 'secure-note')}` before form-actions.
- `identity.ts`: `${renderSections(item, 'identity')}` before form-actions.
- `card.ts`: `${renderSections(item, 'card')}` before form-actions.
- `key.ts`: `${renderSections(item, 'key')}` before form-actions.
- `totp.ts`: `${renderSections(item, 'totp')}` before form-actions.

Each module's `wireFieldHandlers(app)` call (already present at the bottom of each `renderDetail`) picks up the new rows automatically.

- [ ] **Step 3: Verify build + tests still pass**

```bash
cd extension && bun run build 2>&1 | tail -3
cd extension && bun run test 2>&1 | grep -E "Tests|Test Files" | tail -3
```

Expected: build clean; 91 tests pass (unchanged — no new tests, just integration).

- [ ] **Step 4: Commit**

```bash
git add extension/src/popup/components/types/*.ts
git commit -m "feat(ext/popup): render custom sections in all 6 type detail views"
```

## Slice 2 — Custom-fields edit rendering

### Task 3: Add `renderSectionsEditor` + `generateFieldId` helpers + tests

**Files:**
- Modify: `extension/src/popup/components/fields.ts`
- Modify: `extension/src/popup/components/__tests__/sections-render.test.ts` (or add a new `sections-editor.test.ts`)
- Modify: `extension/src/popup/styles.css`

- [ ] **Step 1: Write the failing tests**

Create `extension/src/popup/components/__tests__/sections-editor.test.ts`:

```ts
import { describe, expect, it, vi } from 'vitest';
import { renderSectionsEditor, generateFieldId, wireSectionsEditor } from '../fields';
import type { Section } from '../../../shared/types';

- [ ] **Step 2: Run — tests fail**

```bash
cd extension && bun run test src/popup/components/__tests__/sections-editor.test.ts 2>&1 | tail -10
```

Expected: import errors for `renderSectionsEditor`, `generateFieldId`, `wireSectionsEditor`.

- [ ] **Step 3: Add the helpers to `fields.ts`**

Append to `extension/src/popup/components/fields.ts`:

  });
}
```

- [ ] **Step 4: Add CSS**

Append to `extension/src/popup/styles.css`:

```css
/* --- custom-section editor (β₂ slice 2) --- */
.disclosure {
  border-top: 1px solid #21262d;
  margin-top: 14px;
  padding-top: 10px;
}
.disclosure__toggle {
  background: transparent; border: 0; color: #58a6ff;
  cursor: pointer; font-size: 12px; padding: 0;
  font-family: inherit;
}
.disclosure[data-expanded="false"] .disclosure__body { display: none; }

.section-editor__head {
  display: flex; align-items: baseline; gap: 8px;
  margin-top: 10px; margin-bottom: 4px;
  font-size: 11px;
}
.section-editor__head .name { color: #c9d1d9; font-weight: 600; }
.section-editor__head .name.anon { color: #8b949e; font-style: italic; font-weight: normal; }
.section-editor__head .actions { color: #8b949e; font-size: 10px; margin-left: auto; }
.section-editor__head .actions button {
  background: transparent; border: 0; color: inherit;
  cursor: pointer; padding: 0; margin-left: 8px;
  font: inherit;
}
.section-editor__head .actions button:hover { color: #c9d1d9; }

.section-editor__field {
  display: grid; grid-template-columns: 120px 1fr auto;
  gap: 4px; margin-bottom: 4px; font-size: 11px;
}
.section-editor__field input {
  background: #0d1117; border: 1px solid #30363d; color: #c9d1d9;
  padding: 3px 6px; border-radius: 3px; font: inherit; font-size: 11px;
}
.section-editor__field .delete-field {
  background: transparent; border: 0; color: #f85149;
  cursor: pointer; font-size: 14px; padding: 0 4px;
}

.section-editor__add {
  display: flex; gap: 6px; margin-top: 6px;
}
.section-editor__add button {
  background: transparent; border: 1px solid #30363d; color: #8b949e;
  padding: 2px 10px; border-radius: 3px; cursor: pointer;
  font-size: 10px; font-family: inherit;
}
.section-editor__add button:hover { color: #c9d1d9; border-color: #484f58; }

.disclosure__body .add-section {
  margin-top: 12px; background: transparent;
  border: 1px dashed #30363d; color: #8b949e;
  padding: 6px 10px; border-radius: 4px; cursor: pointer;
  width: 100%; font-size: 11px; font-family: inherit;
}
.disclosure__body .add-section:hover { border-color: #484f58; color: #c9d1d9; }
```

- [ ] **Step 5: Re-run tests — should pass**

```bash
cd extension && bun run test 2>&1 | grep -E "Tests|Test Files" | tail -3
```

Expected: 91 + ~13 = 104 tests pass.

- [ ] **Step 6: Commit**

```bash
cd /home/alee/Sources/relicario/.worktrees/typed-items-1c-beta2
git add extension/src/popup/components/fields.ts \
        extension/src/popup/components/__tests__/sections-editor.test.ts \
        extension/src/popup/styles.css
git commit -m "feat(ext/popup): renderSectionsEditor + wireSectionsEditor helpers"
```

### Task 4: Integrate section editor into all 6 type forms

**Files:**
- Modify: `extension/src/popup/components/types/login.ts`
- Modify: `extension/src/popup/components/types/secure-note.ts`
- Modify: `extension/src/popup/components/types/identity.ts`
- Modify: `extension/src/popup/components/types/card.ts`
- Modify: `extension/src/popup/components/types/key.ts`
- Modify: `extension/src/popup/components/types/totp.ts`

Each of the 6 type modules gets 5 consistent edits. Apply the same pattern to each file:

- [ ] **Step 1: Add imports + module-scope state to each type module**

For each file, extend the `fields` import to include `renderSectionsEditor`, `wireSectionsEditor`:

```ts
import {
  renderRow, renderConcealedRow, renderSignatureBlock,
  wireFieldHandlers, renderSections,
  renderSectionsEditor, wireSectionsEditor,
} from '../fields';
import type { Section } from '../../../shared/types';
```

Add module-scope state near the existing `activeKeyHandler`:

```ts
let sectionsExpanded = false;
```

Extend `teardown()` to reset the expanded flag:

```ts
export function teardown(): void {
  // ... existing cleanup ...
  sectionsExpanded = false;
}
```

- [ ] **Step 2: Initialize the draft in each `renderForm`**

Near the top of each `renderForm`, after reading `existing`:

```ts
const sectionsDraft: Section[] = existing
  ? JSON.parse(JSON.stringify(existing.sections)) as Section[]
  : [];
```

- [ ] **Step 3: Insert `renderSectionsEditor` + wire call into each form**

Find the place in each form's HTML template just before the `<div class="form-actions">` row. Insert:

```ts
${renderSectionsEditor(sectionsDraft, sectionsExpanded)}
```

After `app.innerHTML = ...`, add a `rerender` closure and call `wireSectionsEditor`:

```ts
const rerender = (): void => {
  const disclosure = app.querySelector('.disclosure');
  if (!disclosure) return;
  // Preserve expanded state across rerender.
  sectionsExpanded = disclosure.getAttribute('data-expanded') === 'true';
  disclosure.outerHTML = renderSectionsEditor(sectionsDraft, sectionsExpanded);
  wireSectionsEditor(app, sectionsDraft, rerender);
};
wireSectionsEditor(app, sectionsDraft, rerender);
```

- [ ] **Step 4: Wire the save path**

Find each module's `save*` function (`saveLogin`, `saveSecureNote`, etc.) and locate the `Item` construction:

```ts
const item: Item = {
  // ...
  sections: existing?.sections ?? [],   // ← replace this line
  // ...
};
```

Replace `sections: existing?.sections ?? []` with `sections: sectionsDraft`. Since `sectionsDraft` is deep-cloned from `existing.sections` (or empty for add), mutations through the editor don't affect `existing`.

- [ ] **Step 5: Verify build + tests**

```bash
cd extension && bun run build 2>&1 | tail -3
cd extension && bun run test 2>&1 | grep -E "Tests|Test Files" | tail -3
```

Expected: build clean; 104 tests still pass (no new tests yet — save-shape tests for the editor piggyback on existing per-type save-shape tests in the next step).

- [ ] **Step 6: Add a per-type save-shape smoke test**

Create `extension/src/popup/components/types/__tests__/sections-save.test.ts`:

```ts
import { beforeEach, describe, expect, it, vi } from 'vitest';

vi.mock('../../../popup', async () => {
  const navigate = vi.fn();
  const setState = vi.fn();
  const sendMessage = vi.fn();
  const getState = vi.fn(() => ({
    view: 'add', entries: [], selectedId: null, selectedItem: null, selectedIndex: 0,
    searchQuery: '', activeGroup: null, error: null, loading: false,
    capturedTabId: null, capturedUrl: '', newType: 'login',
    vaultSettings: null, generatorDefaults: null,
  }));
  const escapeHtml = (s: string) => s
    .replace(/&/g, '&amp;').replace(/</g, '&lt;').replace(/>/g, '&gt;')
    .replace(/"/g, '&quot;').replace(/'/g, '&#39;');
  return { navigate, setState, sendMessage, getState, escapeHtml };
});

import { renderForm } from '../login';
import { sendMessage } from '../../../popup';

describe('Login form packs sectionsDraft into Item.sections', () => {
  beforeEach(() => {
    document.body.innerHTML = '<div id="app"></div>';
    vi.mocked(sendMessage).mockReset();
    vi.mocked(sendMessage).mockResolvedValue({ ok: true, data: { id: 'fakeid0000000000', items: [] } });
  });

  it('persists added sections and fields', async () => {
    const app = document.getElementById('app')!;
    renderForm(app, 'add', null);

    (document.getElementById('f-title') as HTMLInputElement).value = 'Example';

    // Open disclosure + add section + add text field
    (document.querySelector('.disclosure__toggle') as HTMLButtonElement).click();
    (document.querySelector('.add-section') as HTMLButtonElement).click();
    (document.querySelector('[data-add-field="text"]') as HTMLButtonElement).click();

    // Populate the new field's label + value
    const labelInput = document.querySelector('[data-field-label="0-0"]') as HTMLInputElement;
    labelInput.value = 'recovery email';
    labelInput.dispatchEvent(new Event('input', { bubbles: true }));
    const valueInput = document.querySelector('[data-field-value-input="0-0"]') as HTMLInputElement;
    valueInput.value = 'backup@example.com';
    valueInput.dispatchEvent(new Event('input', { bubbles: true }));

    document.getElementById('save-btn')!.click();
    await new Promise((r) => setTimeout(r, 5));

    const calls = vi.mocked(sendMessage).mock.calls;
    const addCall = calls.find(([msg]) => (msg as { type: string }).type === 'add_item');
    const msg = addCall![0] as { type: 'add_item'; item: any };
    expect(msg.item.sections).toHaveLength(1);
    expect(msg.item.sections[0].fields).toHaveLength(1);
    expect(msg.item.sections[0].fields[0].label).toBe('recovery email');
    expect(msg.item.sections[0].fields[0].value).toEqual({ kind: 'text', value: 'backup@example.com' });
    expect(msg.item.sections[0].fields[0].id).toMatch(/^[0-9a-f]{16}$/);
  });
});
```

- [ ] **Step 7: Run + commit**

```bash
cd extension && bun run test 2>&1 | grep -E "Tests|Test Files" | tail -3
cd extension && bun run build 2>&1 | tail -3
```

Expected: 104 + 1 = 105 tests; build clean.

```bash
cd /home/alee/Sources/relicario/.worktrees/typed-items-1c-beta2
git add extension/src/popup/components/types/*.ts \
        extension/src/popup/components/types/__tests__/sections-save.test.ts
git commit -m "feat(ext/popup): wire custom-field editor into all 6 type forms"
```

## Slice 3 — Vault-settings SW plumbing

### Task 5: Tighten `VaultSettings` TS types

**Files:**
- Modify: `extension/src/shared/types.ts`

- [ ] **Step 1: Replace the opaque VaultSettings definition**

Find the existing `VaultSettings` interface in `shared/types.ts`:

```ts
export interface VaultSettings {
  trash_retention: unknown;
  field_history_retention: unknown;
  generator_defaults: unknown;
  attachment_caps: unknown;
  autofill_origin_acks: Record<string, number>;
}
```

Replace with tightened types (keeping `attachment_caps` opaque since γ owns it):

```ts
export type TrashRetention =
  | { kind: 'forever' }
  | { kind: 'days'; value: number };

export type HistoryRetention =
  | { kind: 'forever' }
  | { kind: 'last_n'; value: number }
  | { kind: 'days'; value: number };

export interface VaultSettings {
  trash_retention: TrashRetention;
  field_history_retention: HistoryRetention;
  generator_defaults: GeneratorRequest;
  attachment_caps: unknown;                 // opaque — γ tightens
  autofill_origin_acks: Record<string, number>;
}
```

Note: `GeneratorRequest` is already exported from this file. `attachment_caps` stays `unknown` — γ will refine.

- [ ] **Step 2: Verify build**

```bash
cd extension && bun run build 2>&1 | tail -3
```

Expected: clean. No caller tightens consumption of `trash_retention` / `field_history_retention` / `generator_defaults` yet — all downstream reads happen in β₂ slices 3–5 which add those consumers.

- [ ] **Step 3: Commit**

```bash
git add extension/src/shared/types.ts
git commit -m "feat(ext/shared): tighten VaultSettings types for retention + generator_defaults"
```

### Task 6: Add `get_vault_settings` + `update_vault_settings` messages + handlers + router tests

**Files:**
- Modify: `extension/src/shared/messages.ts`
- Modify: `extension/src/service-worker/router/popup-only.ts`
- Modify: `extension/src/service-worker/router/__tests__/router.test.ts`

- [ ] **Step 1: Add message types**

In `extension/src/shared/messages.ts`, add to the `PopupMessage` union:

```ts
  | { type: 'get_vault_settings' }
  | { type: 'update_vault_settings'; settings: VaultSettings }
```

(Import `VaultSettings` from `./types` at the top if not already imported.)

Add both types to the `POPUP_ONLY_TYPES` `Set`:

```ts
const POPUP_ONLY: Array<PopupMessage['type']> = [
  // ... existing ...
  'get_vault_settings',
  'update_vault_settings',
];
export const POPUP_ONLY_TYPES: ReadonlySet<PopupMessage['type']> = new Set(POPUP_ONLY);
```

Do NOT add them to `SETUP_ALLOWED`.

Add a response helper at the bottom of the file:

```ts
export interface VaultSettingsResponse extends Extract<Response, { ok: true }> {
  data: { settings: VaultSettings };
}
```

- [ ] **Step 2: Add SW handlers**

In `extension/src/service-worker/router/popup-only.ts`, inside the message `switch` statement, add:

```ts
case 'get_vault_settings': {
  const handle = session.getCurrent();
  if (!handle || !state.gitHost) return { ok: false, error: 'vault_locked' };
  const settings = await vault.fetchAndDecryptSettings(state.gitHost, handle);
  return { ok: true, data: { settings } };
}

case 'update_vault_settings': {
  const handle = session.getCurrent();
  if (!handle || !state.gitHost) return { ok: false, error: 'vault_locked' };
  await vault.encryptAndWriteSettings(
    state.gitHost, handle, msg.settings,
    'settings: update vault-level config',
  );
  return { ok: true };
}
```

- [ ] **Step 3: Add router tests**

Append to `extension/src/service-worker/router/__tests__/router.test.ts` (near existing describe blocks):

```ts
describe('get_vault_settings / update_vault_settings', () => {
  it('get_vault_settings accepted from popup; returns VaultSettings', async () => {
    const state = makeState();
    primeUnlocked(state);
    const mockSettings = {
      trash_retention: { kind: 'days', value: 30 },
      field_history_retention: { kind: 'forever' },
      generator_defaults: {
        kind: 'random', length: 20,
        classes: { lower: true, upper: true, digits: true, symbols: true },
        symbol_charset: { kind: 'safe_only' },
      },
      attachment_caps: {},
      autofill_origin_acks: { 'github.com': 1000 },
    };
    vi.mocked(vault.fetchAndDecryptSettings).mockResolvedValueOnce(mockSettings as any);
    const res = await route({ type: 'get_vault_settings' }, state, makePopupSender());
    expect(res).toMatchObject({ ok: true });
    if (res.ok) {
      const d = res.data as { settings: typeof mockSettings };
      expect(d.settings).toEqual(mockSettings);
    }
  });

  it('get_vault_settings rejected from content', async () => {
    const state = makeState();
    const res = await route({ type: 'get_vault_settings' }, state, makeContentSender());
    expect(res).toEqual({ ok: false, error: 'unauthorized_sender' });
  });

  it('update_vault_settings accepted from popup; calls encryptAndWriteSettings', async () => {
    const state = makeState();
    primeUnlocked(state);
    vi.mocked(vault.encryptAndWriteSettings).mockResolvedValueOnce(undefined);
    const newSettings = {
      trash_retention: { kind: 'forever' },
      field_history_retention: { kind: 'last_n', value: 5 },
      generator_defaults: {
        kind: 'bip39', word_count: 6, separator: '-', capitalization: 'lower',
      },
      attachment_caps: {},
      autofill_origin_acks: {},
    };
    const res = await route(
      { type: 'update_vault_settings', settings: newSettings as any },
      state,
      makePopupSender(),
    );
    expect(res).toMatchObject({ ok: true });
    expect(vault.encryptAndWriteSettings).toHaveBeenCalledWith(
      expect.anything(), expect.anything(), newSettings, expect.any(String),
    );
  });

  it('update_vault_settings rejected from setup tab (not in SETUP_ALLOWED)', async () => {
    const state = makeState();
    const res = await route(
      { type: 'update_vault_settings', settings: {} as any },
      state,
      makeSetupSender(),
    );
    expect(res).toEqual({ ok: false, error: 'unauthorized_sender' });
  });
});
```

Adapt the `primeUnlocked(state)` / `makePopupSender()` / `makeContentSender()` / `makeSetupSender()` helper invocations to match the existing patterns in the file. If `vault` isn't already mocked at the top of the file via `vi.mock(...)`, add:

```ts
vi.mock('../../vault', () => ({
  fetchAndDecryptSettings: vi.fn(),
  encryptAndWriteSettings: vi.fn(),
  fetchAndDecryptManifest: vi.fn(),
  fetchAndDecryptItem: vi.fn(),
  encryptAndWriteItem: vi.fn(),
  encryptAndWriteManifest: vi.fn(),
  listItems: vi.fn(() => []),
  findByHostname: vi.fn(() => []),
  setWasm: vi.fn(),
}));
```

Check the existing mock set in `router.test.ts` and merge any missing functions.

- [ ] **Step 4: Run tests**

```bash
cd extension && bun run test 2>&1 | grep -E "Tests|Test Files" | tail -3
```

Expected: 105 + 4 = 109 tests pass.

- [ ] **Step 5: Commit**

```bash
git add extension/src/shared/messages.ts \
        extension/src/service-worker/router/popup-only.ts \
        extension/src/service-worker/router/__tests__/router.test.ts
git commit -m "feat(ext/sw): get_vault_settings + update_vault_settings popup-only messages"
```

### Task 7: Add `generate_passphrase` message + handler (if missing)

**Files:**
- Modify: `extension/src/shared/messages.ts`
- Modify: `extension/src/service-worker/router/popup-only.ts`

- [ ] **Step 1: Check if `generate_passphrase` message already exists**

```bash
grep -n "generate_passphrase" extension/src/shared/messages.ts
```

If it's already present (as of β₁), skip to Step 4. Otherwise proceed.

- [ ] **Step 2: Add to PopupMessage + POPUP_ONLY_TYPES**

In `extension/src/shared/messages.ts`:

```ts
  | { type: 'generate_passphrase'; request: GeneratorRequest }
```

Add `'generate_passphrase'` to the `POPUP_ONLY` array.

- [ ] **Step 3: Add SW handler**

In `router/popup-only.ts`, alongside the existing `generate_password` case:

```ts
case 'generate_passphrase': {
  const passphrase = state.wasm.generate_passphrase(JSON.stringify(msg.request));
  return { ok: true, data: { passphrase } };
}
```

- [ ] **Step 4: Verify build + tests still pass**

```bash
cd extension && bun run test 2>&1 | grep -E "Tests|Test Files" | tail -3
cd extension && bun run build 2>&1 | tail -3
```

Expected: tests unchanged (109); build clean.

- [ ] **Step 5: Commit (only if changes were made)**

```bash
git status
git add -A
git commit -m "feat(ext/sw): generate_passphrase popup-only message"
```

If `git status` shows no staged changes (message already existed), skip the commit.

### Task 8: Fetch `vault_settings` at popup init + add to PopupState

**Files:**
- Modify: `extension/src/popup/popup.ts`

- [ ] **Step 1: Extend PopupState**

In `extension/src/popup/popup.ts`, find the `PopupState` interface and add:

```ts
  vaultSettings: import('../shared/types').VaultSettings | null;
  generatorDefaults: import('../shared/types').GeneratorRequest | null;
```

Also extend the `View` union:

```ts
export type View = 'locked' | 'list' | 'detail' | 'add' | 'edit' | 'settings' | 'settings-vault';
```

Add initial values to `currentState`:

```ts
  vaultSettings: null,
  generatorDefaults: null,
```

- [ ] **Step 2: Fetch on unlock**

In `popup.ts#init`, after the `if (data.unlocked)` branch loads entries, add a parallel `get_vault_settings` fetch:

```ts
// Existing code:
// if (data.unlocked) {
//   const listResp = await sendMessage({ type: 'list_items' });
//   if (listResp.ok) { ... }
// }

// Add:
const vsResp = await sendMessage({ type: 'get_vault_settings' });
if (vsResp.ok) {
  const vs = (vsResp.data as { settings: import('../shared/types').VaultSettings }).settings;
  currentState.vaultSettings = vs;
  currentState.generatorDefaults = vs.generator_defaults;
}
```

Place this AFTER the list fetch but BEFORE the `navigate('list', ...)` call so the state is populated before the list view renders.

- [ ] **Step 3: Verify build + tests**

```bash
cd extension && bun run build 2>&1 | tail -3

git add extension/src/popup/components/generator-popover.ts \
        extension/src/popup/components/__tests__/generator-popover.test.ts \

### Task 10: Wire gen button to popover + teardown integration

**Files:**
- Modify: `extension/src/popup/components/types/login.ts`
- Modify: `extension/src/popup/components/types/totp.ts`
- (Other type modules don't have "gen" buttons — only Login and Totp expose a password/secret field.)

- [ ] **Step 1: Update Login's gen-button handler**

In `extension/src/popup/components/types/login.ts`, find the existing gen-btn handler:

```ts
document.getElementById('gen-btn')?.addEventListener('click', async () => {
  const resp = await sendMessage({ type: 'generate_password', request: DEFAULT_PASSWORD_REQUEST });
  if (resp.ok) {
    const data = resp.data as { password: string };
    const pw = document.getElementById('f-password') as HTMLInputElement;
    pw.value = data.password;
    pw.type = 'text';
  } else setState({ error: resp.error });
});
```

Replace with:

```ts
document.getElementById('gen-btn')?.addEventListener('click', (e) => {
  const anchor = e.currentTarget as HTMLElement;
  const initial = getState().generatorDefaults ?? DEFAULT_PASSWORD_REQUEST;
  openGeneratorPopover({
    anchor,
    initial,
    onPicked: (value) => {
      const pw = document.getElementById('f-password') as HTMLInputElement | null;
      if (pw) { pw.value = value; pw.type = 'text'; }
    },
  });
});
```

Add the import at the top of the file:

```ts
import { openGeneratorPopover, closeGeneratorPopover } from '../generator-popover';
```

Extend the existing `teardown()` to close the popover:

```ts
export function teardown(): void {
  // ... existing teardown ...
  closeGeneratorPopover();
}
```

- [ ] **Step 2: Totp doesn't currently have a gen button**

Totp's form has a secret input but no "gen" button today. β₂ doesn't add one — a "generate a TOTP secret" flow would be a γ polish item. Skip Totp changes for this task.

- [ ] **Step 3: Verify build + tests**

```bash
cd extension && bun run build 2>&1 | tail -3
cd extension && bun run test 2>&1 | grep -E "Tests|Test Files" | tail -3
```

Expected: clean; 116 tests unchanged.

- [ ] **Step 4: Commit**

```bash
git add extension/src/popup/components/types/login.ts
git commit -m "feat(ext/popup): login gen-btn opens generator popover; teardown closes it"
```

## Slice 5 — Settings view + ⚙ picker + default wiring

### Task 11: Settings-vault component + tests

**Files:**
- Create: `extension/src/popup/components/settings-vault.ts`
- Create: `extension/src/popup/components/__tests__/settings-vault.test.ts`
- Modify: `extension/src/popup/styles.css`

- [ ] **Step 1: Write the failing tests**

Create `extension/src/popup/components/__tests__/settings-vault.test.ts`:

```ts

- [ ] **Step 3: Add CSS**

Append to `extension/src/popup/styles.css`:

```css
/* --- settings-vault screen (β₂ slice 5) --- */
.settings-header { display: flex; align-items: center; gap: 10px; margin-bottom: 14px; }
.settings-section {
  margin-top: 14px; padding-top: 10px;
  border-top: 1px solid #21262d;
}
.settings-section__title {
  color: #8b949e; font-size: 10px;
  text-transform: uppercase; letter-spacing: 0.08em;
  margin-bottom: 6px;
}
.settings-row {
  display: grid; grid-template-columns: 110px 1fr;
  gap: 6px 10px; align-items: center;
  margin: 4px 0; font-size: 12px;
}
.settings-row__label { color: #8b949e; }
.settings-row select {
  background: #0d1117; border: 1px solid #30363d; color: #c9d1d9;
  padding: 3px 8px; border-radius: 3px; font: inherit; font-size: 11px;

  gap: 8px; align-items: center;
  padding: 4px 0; font-size: 11px;
  border-bottom: 1px solid #161b22;

.ack-row__revoke {
  background: transparent; border: 0; color: #f85149;
  cursor: pointer; font-size: 10px;
}
.settings-footer {
  display: flex; justify-content: flex-end; gap: 6px;
  margin-top: 20px; padding-top: 12px; border-top: 1px solid #21262d;
}
```

- [ ] **Step 4: Run tests**

```bash
cd extension && bun run test 2>&1 | grep -E "Tests|Test Files" | tail -3
```

Expected: 116 + 5 = 121 tests.

- [ ] **Step 5: Commit**

```bash
git add extension/src/popup/components/settings-vault.ts \
        extension/src/popup/components/__tests__/settings-vault.test.ts \
        extension/src/popup/styles.css
git commit -m "feat(ext/popup): vault-settings screen (retention + generator + origin-ack revoke)"
```

### Task 12: Wire ⚙ picker + settings-vault route

**Files:**
- Modify: `extension/src/popup/popup.ts`
- Modify: `extension/src/popup/components/item-list.ts`

- [ ] **Step 1: Add the settings-vault route**

In `extension/src/popup/popup.ts`, find the `render()` function's `switch (currentState.view)` block and add:

```ts
case 'settings-vault':
  // Lazy import to keep bundle chunks focused.
  import('./components/settings-vault').then((m) => m.renderVaultSettings(app));
  break;
```

Or, if all other views use synchronous imports, add:

```ts
import { renderVaultSettings } from './components/settings-vault';
// ...
case 'settings-vault':
  renderVaultSettings(app);
  break;
```

Match the existing import style used by the other view imports.

- [ ] **Step 2: Replace the ⚙ button with a small picker**

In `extension/src/popup/components/item-list.ts`, find the existing settings button handler (something like `document.getElementById('settings-btn')?.addEventListener('click', () => navigate('settings'));`) and replace with a picker, following the pattern from the `showNewTypePicker` helper that β₁ added:

```ts
document.getElementById('settings-btn')?.addEventListener('click', (e) => {
  e.stopPropagation();
  showSettingsPicker(e.currentTarget as HTMLElement);
});
```

Add at the bottom of `item-list.ts`:

```ts
const SETTINGS_OPTIONS: Array<{ view: 'settings' | 'settings-vault'; icon: string; label: string }> = [
  { view: 'settings',       icon: '🖥',  label: 'device settings' },
  { view: 'settings-vault', icon: '🔐',  label: 'vault settings' },
];

function showSettingsPicker(anchor: HTMLElement): void {
  document.querySelectorAll('.settings-picker').forEach((el) => el.remove());

  const picker = document.createElement('div');
  picker.className = 'settings-picker';
  Object.assign(picker.style, {
    position: 'absolute',
    background: '#161b22',
    border: '1px solid #30363d',
    borderRadius: '6px',
    boxShadow: '0 4px 12px rgba(0,0,0,0.4)',
    padding: '4px',
    minWidth: '170px',
    zIndex: '999999',
    fontSize: '12px',
  });

  const rect = anchor.getBoundingClientRect();
  picker.style.top = `${rect.bottom + 4}px`;
  picker.style.left = `${rect.left}px`;

  for (const opt of SETTINGS_OPTIONS) {
    const row = document.createElement('div');
    Object.assign(row.style, {
      padding: '6px 10px', cursor: 'pointer', color: '#c9d1d9',
      borderRadius: '4px', display: 'flex', alignItems: 'center', gap: '8px',
    });
    const iconSpan = document.createElement('span');
    iconSpan.textContent = opt.icon;
    Object.assign(iconSpan.style, { fontSize: '14px', width: '16px', textAlign: 'center' });
    const labelSpan = document.createElement('span');
    labelSpan.textContent = opt.label;
    row.appendChild(iconSpan);
    row.appendChild(labelSpan);
    row.addEventListener('mouseenter', () => { row.style.background = '#21262d'; });
    row.addEventListener('mouseleave', () => { row.style.background = 'transparent'; });
    row.addEventListener('click', (ev) => {
      ev.stopPropagation();
      picker.remove();
      document.removeEventListener('click', closeOnOutside);
      document.removeEventListener('keydown', closeOnEsc);
      navigate(opt.view);
    });
    picker.appendChild(row);
  }

  document.body.appendChild(picker);

  const closeOnOutside = (ev: MouseEvent) => {
    if (!picker.contains(ev.target as Node)) {
      picker.remove();
      document.removeEventListener('click', closeOnOutside);
      document.removeEventListener('keydown', closeOnEsc);
    }
  };
  const closeOnEsc = (ev: KeyboardEvent) => {
    if (ev.key === 'Escape') {
      picker.remove();
      document.removeEventListener('click', closeOnOutside);
      document.removeEventListener('keydown', closeOnEsc);
    }
  };
  setTimeout(() => {
    document.addEventListener('click', closeOnOutside);
    document.addEventListener('keydown', closeOnEsc);
  }, 0);
}
```

Verify `navigate` is already imported at the top of `item-list.ts`. It should be.

- [ ] **Step 3: Verify build + tests**

```bash
cd extension && bun run build 2>&1 | tail -3
cd extension && bun run test 2>&1 | grep -E "Tests|Test Files" | tail -3
```

Expected: clean; 121 tests unchanged.

- [ ] **Step 4: Commit**

```bash
git add extension/src/popup/popup.ts extension/src/popup/components/item-list.ts
git commit -m "feat(ext/popup): ⚙ picker → device/vault settings"
```

### Task 13: Final acceptance + tag

No file changes — pure verification + tag.

- [ ] **Step 1: Rust + WASM target**

```bash
cd /home/alee/Sources/relicario/.worktrees/typed-items-1c-beta2
cargo test --workspace 2>&1 | grep "test result"
cargo build -p relicario-wasm --target wasm32-unknown-unknown 2>&1 | tail -3
```

Expected: 155 tests pass (unchanged from β₁ baseline); WASM builds clean.

- [ ] **Step 2: Extension builds + tests**

```bash
cd extension
bun run test 2>&1 | grep -E "Tests|Test Files" | tail -3
bun run build:all 2>&1 | grep -E "warning|error|compiled" | tail -10
```

Expected: ~121 tests; both bundles compile clean.

- [ ] **Step 3: Lint greps**

```bash
cd /home/alee/Sources/relicario/.worktrees/typed-items-1c-beta2
echo "=== @ts-nocheck (should be empty) ==="
git grep -n '@ts-nocheck' extension/src/
echo "---"
echo "=== idfoto (should be empty) ==="
git grep -n 'idfoto' extension/
echo "---"
echo "=== innerHTML in content/ (should be empty) ==="
git grep -n 'innerHTML\|insertAdjacentHTML' extension/src/content/ | grep -v '^[^:]*:[0-9]*: *//'
```

Expected: all three empty.

- [ ] **Step 4: Manual matrix on Chrome + Firefox**

Build + reload:

```bash
cd extension && bun run build:all
```

Load Chrome: `chrome://extensions` → reload the relicario card (or Load Unpacked from `extension/dist`).
Load Firefox: `about:debugging#/runtime/this-firefox` → Reload (or Load Temporary Add-on on `extension/dist-firefox/manifest.json`).

For the manual matrix:

1. **Custom fields — add**: Add a Login item; in the disclosure, add a section named "recovery codes" with two password fields; save; open detail → sections appear below typed rows; reveal works on each concealed row; copy works on text rows.
2. **Custom fields — edit**: Edit the same item; remove one field; add a text field; save; detail reflects all three changes.
3. **Custom fields — across types**: Repeat (1) on a SecureNote, Card, Key — sections should render identically in detail + edit across all 6 type detail views.
4. **Vault settings — retention**: Click ⚙ → vault settings; change trash retention to `7 days`; save; reload popup → still `7 days`. Change field-history retention to `Last 5`; save; reload → still `Last 5`.
5. **Vault settings — generator**: In vault settings, click "configure ▾" on the generator preview; change kind to BIP39, word count 7; click "save as default"; close popover; preview line shows "BIP39, 7 words, ...". Reload popup → still BIP39. In Login form, click "gen" → popover opens with BIP39 defaults inherited from settings.
6. **Generator popover — Random**: From a Login edit form, click "gen" → popover opens; switch back to Random kind; adjust length slider; toggle classes; preview updates per keystroke; "use this value" fills the password input + unmasks.
7. **Generator popover — validation**: Uncheck all 4 classes in Random → "use this value" disabled; check one → enabled.
8. **Origin-ack revoke**: Open vault settings; revoke an acknowledged origin; save; attempt autofill on that site from a Login item with matching URL → re-triggers the requires-ack flow (per α's content-callable handler).
9. **⚙ picker**: Click the ⚙ button → small picker appears with "device settings" + "vault settings". Each routes correctly.

- [ ] **Step 5: Tag the branch tip**

```bash
git tag plan-1c-beta2-complete
git log --oneline -1
```

(Do NOT push — user decides on push timing.)

## Self-review

### Spec coverage

- Custom fields detail render — Task 1-2 (helper + per-type integration).
- Custom fields edit render — Task 3-4 (helpers + per-type integration + save-shape smoke test).
- VaultSettings TS types tightened — Task 5.
- `get_vault_settings` / `update_vault_settings` messages + SW handlers + router tests — Task 6.
- `generate_passphrase` message (if missing) — Task 7.
- Popup `vaultSettings` + `generatorDefaults` state + fetch on unlock — Task 8.
- Generator popover component + tests + CSS — Task 9.
- Gen-button integration + teardown — Task 10.
- Settings-vault component + tests + CSS — Task 11.
- ⚙ picker + settings-vault route — Task 12.
- Final acceptance + tag — Task 13.

### Placeholder scan

No TBD / TODO / "similar to task N" / ambiguous placeholders. Every code step contains complete code.

### Type consistency

- `renderSections(item, idPrefix)` signature consistent across Task 1 definition and Task 2 call-sites.
- `generateFieldId` / `renderSectionsEditor` / `wireSectionsEditor` signatures consistent across Task 3 definition and Task 4 callers.
- `VaultSettings` shape (`TrashRetention` / `HistoryRetention` / `GeneratorRequest`) consistent between Task 5 type definition, Task 6 handler, Task 8 popup init, Task 11 settings-vault.
- `openGeneratorPopover({ anchor, initial, onPicked })` signature consistent between Task 9 definition, Task 10 Login wire, Task 11 settings-vault "configure" wire.
- `sectionsDraft: Section[]` mutated in place across rerender boundaries — correct since the array reference doesn't change, only its contents.
- `pendingSettings: VaultSettings | null` scoped to `settings-vault.ts` module; initialized per `renderVaultSettings` call; cleared by `teardown()`.
