 - **`config.ts` is proxy-only.** It now holds just the three ports (`FRONTEND_PORT`/`PROXY_PORT`/`PB_PORT` = `2080`/`3456`/`8090`). SvelteKit **never imports `config.ts`** — SvelteKit env vars are declared in `frontend/src/env.ts` and read via `$app/env/*`. Deleted the stale `config.js/.d.ts/.map` artifacts.
 - **`frontend/src/env.ts`** declares: `PROXY_URL` (public, default `http://127.0.0.1:3456`), `SERVER_IP` (public, default `192.168.1.225`), `PB_EMAIL`/`PB_PASSWORD` (private, defaults). `PUBLIC_PB_URL` removed (was the source of a startup crash when unset).
 - **Deleted `frontend/src/lib/server/env.ts`** (untracked). All server modules now `import { PROXY_URL } from '$app/env/public'` (`hono.ts`, `auth.ts`, `+layout.server.ts`, `+page.server.ts`, `preferences`, `join/[code]/[member]`). `admin/+page.server.ts` imports creds from `$app/env/private`.

 ### 2026-08-06 — Added root `shared/` for cross-package code

Both `proxy/src/migrate.ts` (`ensureSchema`) and `proxy/scripts/seed.ts` now iterate `SCHEMA_PLAN`; kills the previous duplicated schema/field-helper definitions in both files.
 - Reason: `timezone.ts` and the PB schema are consumed by more than one package; `shared/` is the root location both can reach. Rule added to RULES.md: shared code lives in `shared/`, never inside `frontend/` or `proxy/`.
 - Note: proxy `tsc --noEmit` already errors on `.ts`-extension imports (`allowImportingTsExtensions` unset) — pre-existing, not from this change. Runtime uses esbuild (build) + tsx (dev), both of which bundle the `shared/` imports correctly. Verified `pnpm build` clean for both packages.

+### 2026-09-11 — Shared-device PIN switching (a computer shared by siblings)
+
+- **Problem:** a single `pb_token` cookie meant joining kid B on the family computer silently logged out kid A; every hand-off needed a fresh parent-issued OTP. Design note: `shared-device.md` (decisions + flows).
+- **Model — the PIN is NOT a login:** it _selects_ among sessions that already exist on the device (`pb_token_<childId>` per child + `pb_active` naming the current one). PIN alone mints nothing on a fresh device; a stolen cookie alone selects nothing. Threat model = sibling mischief; devtools-level bypass explicitly accepted (data is family-scoped, toggles reversible).
+- **Sessions (`session.ts` + `hooks.server.ts`):** children store one httpOnly cookie per account (`pb_token_<id>`, 5d TTL) + `pb_active`. Resolution order: `pb_active` first, then legacy `pb_token` (parents + pre-feature children). Parent login/join clears `pb_active` → supersedes kid mode; kid switches shadow (don't delete) a parent session; `/logout` clears everything. Per-profile removal = picker ✕ → `POST /api/device/remove` (device-local cookie surgery, no session required).
+- **`pins` collection** (superuser-only rules like `otp`): plaintext 3-digit PIN, deliberately parent-recoverable (Q1: View). All access server-side with session-role checks — kids can never read siblings' pins via PB rules. Created on boot via `ensurePins({})` in the always-run migrate path (existing installs — no DB wipe), plus `settings.lockMins` via `SCHEMA_PLAN` + `ensureSettingsFields`.
+- **Endpoints:** `POST /api/switch-user {userId, pin}` — cookie-presence gate, superuser PIN verify, in-memory rate limit (5 fails → 30s), **self-healing**: expired device tokens re-mint via the derived password (server-only) instead of forcing a re-join. `POST /api/pins` — `set` (first-time), `change` (needs current), `ensure` (set-if-missing, used by the join wizard so joining a _second_ shared device doesn't clash with an existing PIN).
+- **Picker (`SharedPicker` component)** — one UI everywhere: top-nav colour-dot (any session), idle-lock overlay, and standalone `/{fam}/switch` landing (fam layout redirects there when kid cookies exist but none is active; join pages excluded from the redirect; `+page.server.ts` sends active sessions home). PIN required on every pick incl. "resume" (deliberate-select property). Standalone footer links: join with a code + parent login.
+- **Join wizard (`JoinPinFlow`):** after OTP redeem → "shared with siblings?" → PIN setup (skipped on "no"), **forced when the device already has other kid sessions**; then straight to the kid's dashboard. All three child join routes updated (root `/join`, `/{fam}/join`, `/{fam}/join/{username}`); parents keep the single-session flow.
+- **Idle lock (client, `lib/client/lock.ts`):** `localStorage[fam_last_active]` written on click/key/touch (throttled 10s) + force-written on `pagehide` → survives browser close/sleep/restart (next launch compares elapsed; live 15s interval mid-session). Default **10 min** (user-set: default 10, not 2-3); parent-adjustable `Off / 2 / 10` in Settings → Family → **Shared computer**. Children only; tab-switches don't lock; two tabs share the timestamp so the active tab arbitrates.
+- **Parent/child PIN UI:** Settings → Invites → All members → **PIN** per member (reveal + give-a-new-PIN modal); child Preferences → **My PIN** (set, or change with current PIN; "forgot? parent can read it out").
+- **Typecheck/build:** `svelte-check` still 4 pre-existing canary errors only (chores RewardType/Frequency ×3, qrcode decl — files untouched by this change); prettier run over touched files. Migration applies on next dev-server boot (migrateOnBoot) — no DB wipe; hooks changes need the dev server restart (auto).
+- **Caveats:** legacy single-cookie child sessions work but don't appear in the picker until re-join; multi-tab concurrency accepted (single-tab-norm on family desktops); `shared-device.md` records the settled open questions (view-not-reset, optional-at-join, no parent switcher, straight-to-dashboard, no cross-family).

+# Shared-device switching (PIN)
+
+Design decisions for children sharing a family computer/tablet — recorded
+2026-09-11. Implements: multi-session cookies, `pins` collection, profile
+picker, and the idle lock.
+
+## Model
+
+- **The PIN is NOT a login.** It selects among sessions that already exist on
+  the device. A PIN alone mints nothing on a fresh device; a stolen cookie
+  alone selects nothing without the PIN. Threat model: sibling mischief on a
+  family device (devtools-level bypass is explicitly accepted — data is
+  family-scoped and actions are reversible).
+- Per-device state lives in cookies:
+  - `pb_token_<userId>` — one httpOnly cookie per child with a session on
+    this device (the "device is logged into both accounts" property).
+  - `pb_active` — which child session is currently active.
+  - `pb_token` — unchanged single session for parents (and legacy children).
+    Parent login supersedes kid mode by clearing `pb_active`; a kid switch
+    shadows (but does not delete) a parent session; resolving order is
+    `pb_active` first, then `pb_token`.
+- Sessions are never the security boundary: the OTP gate still guards each
+  child's first-ever join on a device, and switching re-mints an expired token
+  server-side via the derived password (never exposed to the client).
+
+## `pins` collection
+
+- Superuser-only rules (like `otp`); all reads/writes via server endpoints
+  with session-role checks. Plaintext 3-digit PIN — deliberately recoverable
+  so a parent can read it out (Q1: View, not reset). Child changes their own
+  PIN in Preferences (requires current PIN).
+- Fields: `famId` (rel), `userId` (rel), `pin` (text).
+
+## Switch flow
+
+`POST /api/switch-user { userId, pin }`:
+
+1. Request must carry `pb_token_<userId>` (the profile must be on this
+   device). No session required — the picker is reachable with no active user.
+2. PIN verified server-side via superuser (children must NOT be able to read
+   each other's pins, so collection rules can't be the check).
+3. In-memory rate limit: 5 fails → 30s lockout per userId (3-digit space).
+4. Refresh the device cookie's token; if expired, re-auth with the derived
+   password (heals sessions on switch).
+5. Set `pb_token_<userId>` + `pb_active`; client full-reloads to that child's
+   dashboard URL (`/famSlug/handle`).
+
+Per-profile removal: `POST /api/device/remove { userId }` — deletes that
+cookie (+ `pb_active` if it was active). No session required (device-local
+cookie surgery only).
+
+## Picker
+
+One component (`SharedPicker`) used everywhere:
+
+- TopNav switcher button (always visible when the device has child sessions).
+- Idle-lock return (overlay).
+- `/{famSlug}/switch` — standalone landing when the device has child sessions
+  but no active session (e.g. after per-profile logout). The fam layout
+  redirects unauthenticated device requests to it. Links: "Add a child with a
+  code" → `/{famSlug}/join`, "Parent login" → `/login`.
+
+Every pick (including "resume" as the current kid) requires the PIN.
+
+## Idle lock
+
+- Default 10 min; parent-adjustable in Family Settings: `Off / 2 / 10`
+  (`settings.lockMins`, 0 = off; `shared-device.md` settled default 10).
+- Client-side only, child sessions only (parent sessions never lock).
+- **Only fires when shared-computer mode is ON for the device** (see below) —
+  a personal device never locks, even with lockMins set.
+- `localStorage['fam_last_active']` updated on click/key/touch (throttled
+  10s) and force-written on `pagehide` — survives browser close, sleep and
+  restarts. Next launch compares elapsed time; past the timeout → picker.
+  Live timer (15s interval) does the same mid-session.
+- Resets: join wizard and picker switch write a fresh timestamp before
+  navigating, so freshly-activated sessions don't instantly lock.
+
+## Shared-computer toggle (TopNav)
+
+- **Storage: localStorage, NOT the DB.** Shared-ness is a property of *this
+  browser* — a DB flag on `fams`/`settings` would force PIN mode on every
+  device including a parent's phone. `localStorage['fam_shared_device']`
+  is the source of truth; a plain `fam_shared_device=1` cookie mirrors it
+  so server loads see it (`data.sharedDevice`). Neither is a security
+  boundary — the PIN + device session cookies remain the gate.
+- **Location:** monitor icon in the TopNav (fam layout children slot, next
+  to the profile switcher). Rendered for any role, even logged out —
+  whoever holds the device can mark it shared. Active state: indigo fill.
+- **What it gates:**
+  - Profile switcher (`kid-switch`) button — only shown when shared mode
+    is ON and the device holds child sessions.
+  - Idle lock — only fires for child sessions on shared devices.
+  - (Server `/switch` redirect unchanged — the picker is harmless on
+  - non-shared devices and the server can't do better without the cookie.)
+- **PIN reminders on enable** (`GET /api/pins/status`, set/unset only —
+  values never leave the server except via the settings `revealPin`
+  action):
+  - Parent toggling sees the roster: who still needs a PIN (→ Settings →
+    Members) vs who is ready (→ read the PINs out to them).
+  - A child toggling sees only their own state: "remember your PIN" or
+  - "ask a parent to set one up" (no PIN → picker shows "ask a parent").
+- Client flag helpers: `lib/client/shared-device.ts`
+  (`isSharedDevice` / `setSharedDevice`, writes the cookie mirror too).
+
+## Join flow (child)
+
+After OTP redeem:
+
+1. If the device already has other child sessions → PIN setup (required).
+2. Else ask "Will this computer be shared with a sibling?" — yes → PIN setup;
+   no → skip (PIN can be added later in Preferences; parents can set it in
+   Family Settings).
+3. Land on the child's dashboard.
+
+Parents keep the existing join (set own password, single session).
+
+## Edge cases
+
+- Two tabs share the timestamp → the active tab keeps the other from locking.
+- Tab switches don't lock (kids alt-tab constantly).
+- Expired sessions: the picker still shows the profile; switching re-mints.
+- No PIN set on a profile → picker shows "ask a parent to set it up".
