+# Phase 10: Admin Role & Settings - Context
+
+**Gathered:** 2026-06-12
+**Status:** Ready for planning
+
+
+## Phase Boundary
+
+Phase 10 introduces an admin role and the role-gated Admin Settings surface, and carries the v1.1 DB-foundation migration that Phases 11–12 consume.
+
+**Delivers:**
+
+- **DB foundation:** `users.is_admin` + a new `app_config` table + `calendar_events.reminder_lead_minutes` — all three shipped in this phase's migration (per the ROADMAP DB-foundation note: the v1.1 schema migration is "carried by Phase 10"). `is_admin` and `app_config` are used here; `reminder_lead_minutes` is created-now / consumed by Phase 11; `app_config.setup_complete` is created-now / consumed by Phase 12.
+- **Admin role (ADMIN-03):** a role check gating admin routes/UI; non-admins cannot reach or invoke them. First-login-wins bootstrap (see D-01).
+- **App-password / credential management (ADMIN-01):** an admin can view household members and rotate / re-enter a member's provider credential from the UI; validated against the provider (CalDAV PROPFIND for Fastmail) before saving, stored encrypted via the existing `crypto.ts` / `APP_PASSWORD_ENCRYPTION_KEY` path; never displayed, logged, or echoed.
+- **Shared-calendar designation (ADMIN-02):** an admin picks which synced calendar is the shared family calendar (`calendars.is_shared`) from the UI, replacing the manual DB write.
+
+**NOT in this phase:** the Phase 12 setup wizard itself; per-event reminder UI/scheduling (Phase 11); full multi-provider support (backlog 999.1 — only the generic *shape* lands here, Fastmail/CalDAV is the only implemented provider); self-service credential onboarding (backlog 999.5).
+
+
+
+## Implementation Decisions
+
+### Admin bootstrap (ADMIN-03)
+- **D-01: First-login-wins.** When no admin exists, the first user to log in is flagged `is_admin=true`; subsequent users are normal members. Chosen deliberately to dovetail with Phase 12: the first login *after setup completes* becomes the admin. Must stay member-count-agnostic — the flag is a per-user boolean, not a hardcoded single-admin assumption, so more admins can be promoted later.
+ - **Phase-12 interaction to honor:** the "first login" that wins admin should ultimately be the first login *after* `app_config.setup_complete`. Phase 12 owns `setup_complete`; Phase 10 ships the column and the first-login-wins logic. Planner should implement the bootstrap so it reads cleanly once `setup_complete` gating is layered on in Phase 12 (e.g. "first user when zero admins exist" today, tightened to "first user after setup_complete" in P12) — do not hardcode anything that Phase 12 would have to rip out.
+ - **Dev note:** under `DEV_AUTH_BYPASS`, `DEV_USER` (id 1) is injected without a DB upsert. Decide and document how the dev/bypass user acquires `is_admin` for local admin-UI verification (e.g. seed id 1 as admin, or have the bypass path flag it) — see [[dev-data-user1-no-calendars]].
+
+### Admin UI entry & gating
+- **D-02: New `/admin` route.** A dedicated gated route (not an extension of the existing notifications `SettingsSheet`). An `is_admin` guard redirects non-admins away. Gives Phase 12's wizard room to grow on the same route surface. The existing avatar `SettingsSheet` (notifications toggle) stays as-is.
+- **D-03: Expose `is_admin` on `/api/me`.** The PWA needs the flag to render/guard the `/admin` entry; `/api/me` currently returns only `{ id, displayName, color }` and must add `isAdmin`. The server still enforces the role on every `/api/admin/*` route — the client flag is for UX only, never the security boundary (ADMIN-03 is server-enforced).
+
+### Credential model (ADMIN-01)
+- **D-04: Generic provider shape, Fastmail-only implementation.** Add a provider/type discriminator to the credential model and frame the admin UI around "a provider credential" (avoid hardcoded "Fastmail app password" copy in the data model / API). Implement and validate ONLY Fastmail/CalDAV (PROPFIND) now. Gmail/other providers are wiring left for backlog 999.1 — do **not** build a second provider here. See [[project-nmember-expansion]] and backlog 999.1.
+- **D-05: Per-member provider credential.** Keep `member_credentials` per-user; each member owns their credential row (today both rows happen to hold the same shared Fastmail account per D-16, but the model stays N-member / N-provider ready). An admin can rotate **any** member's credential. Reuse the existing encryption path; never expose the plaintext.
+
+### Shared-calendar designation (ADMIN-02)
+- **D-06: Exclusive single-select.** The admin picks exactly one synced calendar as the shared family calendar. Setting a new one clears `is_shared` on any prior shared calendar (single shared calendar, matching the core value). Picker lists the synced calendars; selection is a radio/toggle, not independent multi-toggles.
+
+### Claude's Discretion
+- **Migration packaging:** ship the full v1.1 column/table bundle (`is_admin`, `app_config`, `reminder_lead_minutes`) in one Phase-10 migration per the ROADMAP note, so Phases 11/12 don't each carry their own migration. Use `drizzle-kit generate` + `migrate` — never `push` (see [[drizzle-mariadb-push-unsafe]]).
+- **`app_config` shape:** create the table now with at least a `setup_complete` flag (Phase 12). Add other global keys only as Phase 10 actually needs them; keep it a simple key/value or single-row config — planner's call.
+- **`/api/admin/*` route layout:** sub-routes for members/credentials and shared-calendar — planner decides exact paths, following the existing `routes/*.ts` Hono pattern.
+- Server-side admin middleware shape (a `requireAdmin` guard analogous to the existing auth middleware) — planner's call.
+
+
+
+
+## Canonical References
+
+**Downstream agents MUST read these before planning or implementing.**
+
+### Requirements & roadmap
+- `.planning/REQUIREMENTS.md` — ADMIN-01, ADMIN-02, ADMIN-03 (full wording + the "Role-agnostic design" note); the DB-foundation note coupling the v1.1 migration to Phase 10; the deferred items (self-service onboarding 999.5, audit log/user-CRUD out of scope).
+- `.planning/ROADMAP.md` §Phase 10 — phase goal, success criteria, dependency chain (10 → 11, 10 → 12).
+- `.planning/phases/999.1-treat-fastmail-as-a-provider-support-more-calendar-providers/` — the backlog phase that D-04's generic shape is designed to plug into. Read for the provider-abstraction direction so Phase 10's credential model doesn't paint 999.1 into a corner.
+
+### Codebase maps
+- `.planning/codebase/ARCHITECTURE.md` — overall API/PWA architecture + the ordering rationale that folded the migration into Phase 10.
+- `.planning/codebase/STRUCTURE.md` — where routes / schema / frontend pages live.
+- `.planning/codebase/CONVENTIONS.md` — naming + module patterns to match.
+
+### Key source files
+- `apps/api/src/db/schema.ts` — `users` (add `is_admin`), `calendars` (`is_shared` already exists, l.89), `member_credentials` (add provider discriminator), `calendar_events` (add `reminder_lead_minutes`). New `app_config` table.
+- `apps/api/src/broker/crypto.ts` — `encryptPassword` / `decryptPassword` (reuse for ADMIN-01).
+- `apps/api/src/broker/client.ts` — `createDAVClient` / `fetchCalendars` (reuse for CalDAV PROPFIND credential validation).
+- `apps/api/src/index.ts` — route mounting + auth middleware order (mount `/api/admin/*` behind the auth guard, add a `requireAdmin` layer).
+- `apps/api/src/routes/me.ts` + `apps/api/src/auth/devBypass.ts` + `apps/api/src/auth/user.ts` — current-user resolution; where to add `isAdmin` to the `/api/me` response and bootstrap the flag on upsert.
+- `apps/pwa/src/App.tsx` — `BrowserRouter` routes (add gated `/admin`); `SettingsSheet` entry pattern.
+- `apps/pwa/src/api/client.ts` — `/api/me` client type (add `isAdmin`).
+
+
+
+
+## Existing Code Insights
+
+### Reusable Assets
+- `crypto.ts` (`encryptPassword`/`decryptPassword`, AES-256-GCM via `APP_PASSWORD_ENCRYPTION_KEY`): the exact store path ADMIN-01 must reuse — no new crypto.
+- `member_credentials` table (per-user, JSON `{iv,authTag,ciphertext}` + `fastmail_email`): extend with a provider discriminator rather than replace.
+- `broker/client.ts createDAVClient` + `fetchCalendars`: drives CalDAV PROPFIND — reuse to validate a credential before save (SETUP-02 also reuses this in P12).
+- `auth/devBypass.ts` `c.get('user')` pattern: how routes read the current user; the `requireAdmin` guard and admin routes follow the same context-user pattern.
+- `SettingsSheet` (avatar-opened): existing settings UX precedent; `/admin` is a sibling, not a replacement.
+
+### Established Patterns
+- Routes are per-feature Hono routers under `apps/api/src/routes/`, mounted in `index.ts` behind `devAuthBypass()` → `oidcAuthMiddleware()` on `/api/*`. Admin routes mount in the same protected band, plus a `requireAdmin` check.
+- Schema migrations via `drizzle-kit generate` + `migrate` (NOT `push` — [[drizzle-mariadb-push-unsafe]]).
+- Identity is `oidc_iss + oidc_sub`, never email (D-10); `upsertUser` is the bootstrap hook for first-login-wins.
+- PWA routing is declarative `react-router` `` in `App.tsx`; server state via TanStack Query, UI-only state via Zustand.
+
+### Integration Points
+- `/api/me` response → add `isAdmin`; PWA `meQuery` consumers gate the `/admin` nav entry.
+- `upsertUser` (`auth/user.ts`) → first-login-wins flag write.
+- `calendars.is_shared` write moves from manual DB edit to the ADMIN-02 endpoint; the calendar legend / shared-calendar consumers already read `is_shared`.
+- `app_config.setup_complete` → consumed by Phase 12; `calendar_events.reminder_lead_minutes` → consumed by Phase 11.
+
+
+
+
+## Specific Ideas
+
+- The credential UI/data model should read as "provider credential," not "Fastmail app password" — the user explicitly wants Gmail/other providers pluggable later without reshaping the schema (D-04). Fastmail is just the first/only implemented provider.
+- First-login-wins was chosen *specifically* because Phase 12's setup wizard precedes it: the operator who completes setup is the first to log in and becomes admin (D-01).
+
+
+
+
+## Deferred Ideas
+
+- **Full multi-provider support (Gmail/other)** — backlog 999.1. Phase 10 lands only the generic credential *shape*; actual additional providers + their validation are 999.1.
+- **Self-service credential onboarding** (a member adds their own app password on first login) — backlog 999.5; Phase 10 is admin-managed only.
+- **Admin audit log / health dashboard / user CRUD** — explicitly out of scope per REQUIREMENTS.md (scope creep for a small self-hosted app).
+- **Multiple reminders per event** — v1.2 stretch (noted in REQUIREMENTS.md, unrelated to Phase 10).
+
+### Reviewed Todos (not folded)
+- `2026-06-10-gitea-ci-regression-and-docker-publish.md` ("Gitea CI — full regression + Docker publish") — matched only on weak generic keywords (build/api/phase); it is Phase 8 work already completed. Not relevant to Phase 10; not folded.

+# Phase 10: Admin Role & Settings - Discussion Log
+
+> **Audit trail only.** Do not use as input to planning, research, or execution agents.
+> Decisions are captured in CONTEXT.md — this log preserves the alternatives considered.
+
+**Date:** 2026-06-12
+**Phase:** 10-admin-role-settings
+**Areas discussed:** Admin bootstrap, Admin UI entry, App-password/credential scope, Shared-calendar designation, Provider scope, Credential ownership
+
+---
+
+## Admin bootstrap
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Env-pinned OIDC sub | `ADMIN_OIDC_SUB` marks operator identity as admin | |
+| First-login-wins | First user to log in is auto-admin | ✓ |
+| Everyone admin for now | Flag all members admin, defer gating | |
+| Manual DB seed | Keep setting `is_admin` by hand | |
+
+**User's choice:** First-login-wins
+**Notes:** Chosen because Phase 12's setup wizard precedes it — the first login *after setup completes* becomes admin. Must stay member-count-agnostic.
+
+---
+
+## Admin UI entry
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Extend SettingsSheet | Add an Admin section to the existing avatar sheet | |
+| New /admin route | Dedicated gated route, redirect non-admins | ✓ |
+| Settings route + sheet stays | Separate gated /admin, keep notifications sheet | |
+
+**User's choice:** New /admin route
+**Notes:** Existing notifications `SettingsSheet` stays; `/admin` gives Phase 12's wizard room on the same surface.
+
+---
+
+## App-password / credential scope
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Per-member rows, admin edits any | Per-user credentials, admin rotates any | (see provider redirect) |
+| Per-member, self-only + admin override | Members manage own; admin overrides | |
+| Single shared credential | One household credential | |
+
+**User's choice:** Redirected — "treat Fastmail like a provider; design generically enough to plug in Gmail/other providers later." Resolved in the Provider-scope and Credential-ownership follow-ups below.
+**Notes:** Ties into backlog 999.1 (treat-fastmail-as-a-provider).
+
+---
+
+## Shared-calendar designation
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Exclusive single-select | Pick exactly one shared calendar; clears prior | ✓ |
+| Multi-select toggles | Mark multiple calendars shared | |
+
+**User's choice:** Exclusive single-select
+**Notes:** Matches the "one shared family calendar" core value.
+
+---
+
+## Provider scope (follow-up)
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Generic shape, Fastmail-only impl | Add provider field + generic UI; implement only Fastmail/CalDAV | ✓ |
+| Fastmail-only, refactor later | Narrow build now, full refactor in 999.1 | |
+| Full provider abstraction now | Build pluggable layer + 2nd provider | |
+
+**User's choice:** Generic shape, Fastmail-only impl
+**Notes:** Gmail/others = wiring left for backlog 999.1. Keeps Phase 10 shippable without scope creep.
+
+---
+
+## Credential ownership (follow-up)
+
+| Option | Description | Selected |
+|--------|-------------|----------|
+| Per-member provider credential | Per-user rows + provider field, N-member ready | ✓ |
+| Household-level credential | One record for the household | |
+
+**User's choice:** Per-member provider credential
+**Notes:** Today both rows hold the same shared Fastmail account (D-16) but model stays N-member/N-provider ready; admin can rotate any member's.
+
+---
+

+- Migration packaging — ship the full v1.1 bundle (`is_admin`, `app_config`, `reminder_lead_minutes`) in one Phase-10 migration (generate+migrate, not push).
+- `app_config` table shape — create with at least `setup_complete`; add keys as needed.
+- `/api/admin/*` route layout and the `requireAdmin` server middleware shape.
+- How the dev-bypass user (id 1) acquires `is_admin` for local verification.
+
+## Deferred Ideas
+
+- Full multi-provider support (Gmail/other) — backlog 999.1.
+- Self-service credential onboarding — backlog 999.5.
+- Admin audit log / health dashboard / user CRUD — out of scope (REQUIREMENTS.md).
