+# Phase 20: Admin Member Editor & Form Declutter - Pattern Map
+
+**Mapped:** 2026-06-18
+**Files analyzed:** 5 (2 new surfaces, 3 modified)
+**Analogs found:** 5 / 5 (all in-repo, recent)
+
+> No RESEARCH.md for this phase — this is a client-side rework over existing `/api/admin` endpoints. Every new file copies a concrete in-repo analog; no external pattern is needed.
+

+
+## File Classification
+
+| New/Modified File | Role | Data Flow | Closest Analog | Match Quality |
+|-------------------|------|-----------|----------------|---------------|
+| `apps/pwa/src/components/MemberEditorSheet.tsx` (NEW) | component (dialog/sheet) | request-response (form → mutation) | `apps/pwa/src/components/CredentialSheet.tsx` + `ResetPasswordSheet` (in `AdminPage.tsx`) | exact |
+| `apps/api/src/routes/admin.ts` — new `PATCH /members/:id` (NEW route, MODIFIED file) | route (member-profile update) | CRUD (update) | `admin.ts` `POST /members/:id/password` (`:225`) + last-admin count in `auth/user.ts:151` | exact |
+| `apps/pwa/src/routes/AdminPage.tsx` (MODIFIED) | route/page (MemberRow + triggers) | request-response | `ListCard.tsx` (tappable row + ChevronRight) + existing `MemberRow` (`:1151`) | exact |
+| `apps/pwa/src/api/client.ts` (MODIFIED) | api client (type + fetcher) | request-response | `fetchAdminResetPassword` (`:218`) / `fetchCreateMember` (`:184`) | exact |

+
+---
+
+## Pattern Assignments
+
+### `apps/pwa/src/components/MemberEditorSheet.tsx` (component, dialog/sheet)
+
+**Primary analog:** `apps/pwa/src/components/CredentialSheet.tsx`
+**Secondary analog:** `ResetPasswordSheet` inside `apps/pwa/src/routes/AdminPage.tsx:1391` (password+confirm+mismatch logic to fold into the "Set new password" section per D-06).
+
+This is the central new file. Copy the **entire dialog scaffold** from CredentialSheet, then compose the three edit-mode sections (Profile / Set new password / App password) + the create-mode form from existing field/mutation snippets.
+
+**Imports pattern** (`CredentialSheet.tsx:25-35`):
+```typescript
+import { useState, useEffect, useRef, useCallback } from 'react';
+import { useMutation, useQueryClient } from '@tanstack/react-query';
+import { Loader2 } from 'lucide-react';
+import {
+ saveCredential,
+ type SaveCredentialPayload,
+} from '../api/client.js';
+import { useIsPhone } from '../hooks/useIsPhone.js';
+import { useFocusTrap } from '../hooks/useFocusTrap.js';
+```
+For Phase 20 also import the new `updateMemberProfile` fetcher + existing `fetchAdminResetPassword`, and add `ChevronRight`/`Plus` are NOT needed here (those go in AdminPage).
+
+**`mode` prop pattern** — model the create/edit discriminator on `CredentialSheetMode` (`CredentialSheet.tsx:37`). UI-SPEC §Surface B wants a single `mode: 'edit' | 'create'` prop (id present = edit). Mirror the `headingFor(mode)` switch (`CredentialSheet.tsx:54-58`) for "Edit member" / "Add member" copy.
+
+**Dialog scaffold — copy verbatim** (`CredentialSheet.tsx`):
+- `useFocusTrap(dialogRef)` wiring (`:88-89`) + `onKeyDown={handleDialogKeyDown}` on the dialog div (`:186`)
+- `handleClose` via `useCallback` that clears form state, calls `onClose()`, and returns focus to `triggerRef.current` (`:94-103`)
+- Escape-to-close effect (`:106-115`)
+- Focus-heading-on-open effect (`:118-122`)
+- Backdrop div (`:169-178`) — note UI-SPEC §Surface B wants `rgba(0,0,0,0.32)` / `--color-overlay`, which matches `ResetPasswordSheet:1459` (`var(--color-overlay, rgba(0,0,0,0.32))`), NOT CredentialSheet's `rgba(0,0,0,0.4)`. Prefer the ResetPasswordSheet overlay token.
+- Phone-vs-desktop sheet style object (`:187-217`) — copy exactly (borderRadius `12px 12px 0 0` phone / `12px` desktop, `maxWidth 480px`, zIndex 301, `padding var(--space-6)`, desktop `maxHeight: calc(100dvh - var(--space-8)); overflowY: auto`)
+- `h2 ref={headingRef} tabIndex={-1}` heading (`:220-233`)
+- Member subtitle block (`:236-247`) — edit mode only
+
+**Section divider** (UI-SPEC §Surface B): `border-top: 1px solid var(--color-border-subtle)`, `margin: var(--space-6) 0`. Section headings reuse `sectionLabelStyle` from `AdminPage.tsx:46-53` (13px/600/uppercase/`--color-text-muted`) — UI-SPEC Accessibility note says use `
` not `
` to avoid heading-hierarchy issues under the ``.
+
+**Text input field pattern** (`CredentialSheet.tsx:250-283` email field; `AdminPage.tsx:477-495` display-name field) — label (13px/600) + input (`min-height 44px`, `border-radius var(--space-1)`, `padding var(--space-3) var(--space-4)`, `border` flips to `--color-destructive` on error).
+
+**Password section (Section 2)** — copy `ResetPasswordSheet`'s new-password + confirm fields and mismatch logic:
+```typescript
+// AdminPage.tsx:1426-1443 — mutation with client-side mismatch guard
+const resetMutation = useMutation({
+ mutationFn: async () => {
+ if (newPassword !== confirmPassword) throw new Error('mismatch');
+ await fetchAdminResetPassword(member.id, newPassword);
+ },
+ onSuccess: () => { handleClose(); onSuccess?.(); },
+ onError: (err) => {
+ const msg = err instanceof Error ? err.message : 'server';
+ if (msg === 'mismatch') setError('Passwords do not match.');
+ else setError('Something went wrong. Please try again.');
+ },
+});
+```
+UI-SPEC adds a `< 8 chars` guard ("Password must be at least 8 characters.") — mirror the create-member length check at `AdminPage.tsx:267-269`. Fields use `autoComplete="new-password"`, never prefilled (T-10-15/16). **Per-section** save (not handleClose-on-success) — Section 2 success keeps the sheet open and fires toast "Password updated." Only render this section when `member.hasLocalCredential === true`.
+
+**App-password section (Section 3)** — copy CredentialSheet's email + password fields (`:249-320`), the "Validating against CalDAV…" `Loader2` inline state (`:337-345`), the helper link to Fastmail device tokens (`:351-362`), and the FAILURE_TEXT copy (`:65-66`). The mutation maps to `saveCredential` (`:124-153`) — admin mode requires `userId: memberId`. Prefill `fastmailEmail` read-only convenience in edit mode (Claude's-discretion D — the stored `fastmailEmail` exists on `memberCredentials.fastmail_email`, but is NOT currently returned by `GET /members`; the password field is never prefilled).
+
+**Create-mode form (single form, no dividers)** — copy the four fields + mutation from `AdminPage.tsx:260-306` (`createMemberMutation`): display name / username / initial password / confirm. Maps to `fetchCreateMember` (`client.ts:184`). Reuse the exact error mapping (`mismatch` / `short` / `conflict` → "That username is already in use.").
+
+**Per-section Save button** (`CredentialSheet.tsx:397-419`): accent `--color-member-0` background when enabled, `--color-border` when disabled, white text, `min-height 44px`, `border-radius var(--space-1)`, inline `Loader2 size={14}` while pending (pattern at `AdminPage.tsx:651-657`).
+
+**Cancel button** (`CredentialSheet.tsx:375-395`): no background, `--color-text-secondary`, `min-height 44px`.
+
+---
+
+### `apps/api/src/routes/admin.ts` — NEW `PATCH /members/:id` (route, CRUD update)
+
+**Primary analog:** `POST /members/:id/password` (`admin.ts:225-269`) — same `:id` param shape, same `requireAdmin` boundary, same noEchoHook posture, same existence-check-then-update flow.
+**Secondary analog:** the admin-count query in `auth/user.ts:151-156` — reuse for the D-03 last-admin guard.
+
+**Route handler shape — copy** (`admin.ts:225-269`):
+```typescript
+const updateMemberSchema = z.object({
+ displayName: z.string().min(1).max(256).optional(),
+ isAdmin: z.boolean().optional(),
+});
+
+adminRouter.patch(
+ '/members/:id',
+ zValidator('json', updateMemberSchema, noEchoHook),
+ async (c) => {
+ const targetId = parsePositiveIntParam(c.req.param('id')); // :87
+ if (targetId === null) return c.json({ error: 'Invalid member id' }, 400);
+ const { displayName, isAdmin } = c.req.valid('json');
+ // ... existence check + last-admin guard + update
+ },
+);
+```
+- `parsePositiveIntParam` already exists (`admin.ts:87-92`) — reuse, do NOT re-implement.
+- `requireAdmin` is already mounted router-wide (`admin.ts:47`) — the new route inherits it automatically; **no new boundary** (D-02).
+- `noEchoHook` (`admin.ts:75-79`) — apply even though no password is in this body, for consistency with the other admin write routes.
+
+**Last-admin guard (D-03) — adapt from `auth/user.ts:151-156`:**
+```typescript
+// Count remaining admins; reject demotion of the only admin.
+const [{ count }] = await db
+ .select({ count: sql`COUNT(*)` })
+ .from(users)
+ .where(eq(users.isAdmin, true))
+ .limit(1);
+```
+When `isAdmin === false` is requested for a target that is currently an admin AND `Number(count) <= 1`, return 409 (or 422) `{ error: ... }`. UI-SPEC client maps this to "Cannot remove admin — at least one admin must remain." Note: `sql` and `eq` are already imported (`admin.ts:28`).
+
+**Update + error handling** — mirror the try/catch + 503 fallback of the password route (`admin.ts:249-268`). Build a partial `set({ ... })` from whichever of `displayName` / `isAdmin` is present. Verify the target user exists (404 if not), matching the password route's `if (!credRow) return 404` shape (`:245`).
+
+**Verb choice (Claude's discretion, D-02):** Hono supports `adminRouter.patch(...)`. The repo's existing admin writes use `POST` (`/members`, `/credentials`) and `PUT` (`/calendars/:id/shared`, `/config/timezone`); a `PATCH` for partial member update is idiomatic and consistent with REST, but `POST /members/:id` is equally acceptable — planner's call.
+
+---
+
+### `apps/api/src/routes/admin.ts` — `GET /members` adds `isAdmin` (route, CRUD read)
+
+**Analog:** the existing handler itself (`admin.ts:102-124`). Add `isAdmin` to the select and the mapped object:
+```typescript
+.select({
+ id: users.id,
+ displayName: users.displayName,
+ color: users.color,
+ isAdmin: users.isAdmin, // NEW — feeds the editor toggle initial state (D-02)
+ credentialId: memberCredentials.id,
+ localCredId: localCredentials.id,
+})
+// ...
+const members = rows.map((row) => ({
+ id: row.id,
+ displayName: row.displayName,
+ color: row.color,
+ isAdmin: row.isAdmin, // NEW
+ hasCredential: row.credentialId !== null,
+ hasLocalCredential: row.localCredId !== null,
+}));
+```
+`users.isAdmin` already exists in the schema (`db/schema.ts:56`, `boolean('is_admin')`). No join change needed — it's a column on the base `users` table already in the FROM.
+
+---
+
+### `apps/pwa/src/api/client.ts` (api client — type + fetcher)
+
+**Analog for the type:** `AdminMember` interface (`client.ts:563-569`). Add `isAdmin: boolean`:
+```typescript
+export interface AdminMember {
+ id: number;
+ displayName: string | null;
+ color: string;
+ isAdmin: boolean; // NEW — Phase 20 (drives editor admin toggle initial state)
+ hasCredential: boolean;
+ hasLocalCredential: boolean;
+}
+```
+
+**Analog for the new fetcher:** `fetchAdminResetPassword` (`client.ts:218-234`) — same `:id` path, same POST/PATCH-with-json shape, same error handling. New `updateMemberProfile`:
+```typescript
+export async function updateMemberProfile(
+ memberId: number,
+ body: { displayName?: string; isAdmin?: boolean },
+): Promise {
+ const res = await fetch(`/api/admin/members/${memberId}`, {
+ method: 'PATCH', // match the chosen route verb
+ headers: { 'Content-Type': 'application/json' },
+ credentials: 'include',
+ redirect: 'manual',
+ body: JSON.stringify(body),
+ });
+ if (res.type === 'opaqueredirect' || res.status === 401) throw new SessionExpiredError();
+ if (res.status === 409 || res.status === 422) throw new Error('last-admin'); // D-03 guard
+ if (!res.ok) throw new Error(`updateMemberProfile failed: ${res.status}`);
+}
+```
+The `SessionExpiredError` + `handleAuthResponse` conventions are already in this file (used by every fetcher). Map the last-admin 409/422 to a sentinel the editor's onError can branch on (mirrors the `conflict` sentinel pattern at `client.ts:206`).
+
+---
+
+### `apps/pwa/src/routes/AdminPage.tsx` (route/page — MemberRow rework + triggers)
+
+**MemberRow → tappable row analog:** `apps/pwa/src/components/ListCard.tsx` — a whole-row `
