+# The REAL phc_* key is pasted into apps/web/.env.local at Wave 1 / P2b

+# PR7b Auth — Clerk publishable key (shared instance with apps/www). Public-safe by
+# design (ships in the client bundle); the SECRET key is server-side only and is NOT
+# used by the desktop SPA (the local sidecar authorizes with its device token, not a
+# Clerk JWT). Absent → /auth degrades to the accountless local-first state (honest).
+# Like VITE_POSTHOG_KEY, this is baked into the Tauri bundle at compile time.
+# Leave BLANK/commented here: the key is shape-validated (isPublishableKey), so a
+# non-empty placeholder would be rejected anyway — but shipping it blank guarantees a
+# verbatim copy degrades to the honest accountless state, never a crash.

+# Persona Bee Avatars
+
+AI-generated bee mascots — **one unique avatar per Waggle persona (22/22)**,
+wired in `apps/web/src/lib/personas.ts` (AVATAR_MAP, 1:1 by persona id).
+
+**Wave Q (2026-07-06): the whole set was redrawn in the canonical
+flat-geometric hex-bee language** — the same style as the landing personas grid
+(`apps/www/public/brand/bee-*-dark.png`). The R9 5-judge panel flagged the
+previous glossy cel-shaded sticker set as a second illustration dialect
+("two mascot languages"); one dialect now covers landing + app.
+
+## Style (canonical)
+
+Flat geometric vector bee: hexagonal head, simple black dot eyes with white
+glints, small smile, black-striped hexagon body, thick black outlines directly
+on the shapes, flat golden honey palette (#e5a000 family, ~40° hue), NO
+gradients, NO glow, NO background scene, transparent background. Each avatar
+carries one distinct persona prop (quill+hex notebook, hex scales, megaphone,
+interlocking hex gears, …). Reads clearly at 64px.
+
+## Regeneration recipe (proven 2026-07-06)
+
+1. Generate with `nano-banana` (key: `~/.nano-banana/.env`; pass `--api-key`
+   if a stale `GOOGLE_API_KEY` env shadows it), using THREE style references
+   from the landing set + transparency:
+
+   ```bash
+   nano-banana "<BASE + persona prop>" \
+     -r bee-builder-dark.png -r bee-hunter-dark.png -r bee-orchestrator-dark.png \
+     -t -m pro -s 1K -a 1:1 -o <persona-id> -d <outdir>
+   ```
+
+   Batch script with all 22 prompts: session scratchpad `gen-flat-avatars.sh`
+   (2026-07-06); BASE prompt is embedded there.
+
+2. **Palette-correct** — generations consistently come out ~30° burnt-orange
+   instead of the refs' ~40° gold. Deterministic PIL pass (scratchpad
+   `fix-avatars.py`): halo rim → transparent, interior near-white → warm cream
+   #f7e8c8, orange family +10.5° hue / +0.02 sat. Verify: dominant hue of
+   opaque colored pixels should land 39-41°.
+
+3. Drop the PNGs here named `<persona-id>.png` — imports in
+   `lib/personas.ts` are 1:1 by id.
+
+Cost: ~$0.10/image (pro, 1K). Full 22-set ≈ $2.2.

+/**
+ * UX Refactor v2.1 P1a Stage B — ChatHost keep-alive (conversion plan §4.2,
+ * deviation §9.12).
+ *
+ * Mounts ONE ChatWindowInstance (component untouched) per workspace VISITED
+ * this session (i.e. whose /workspaces/:id/chat route has been active), keyed
+ * by workspaceId, and keeps it ALIVE — hidden, not unmounted — when the route
+ * is elsewhere, so in-flight useChat SSE streams survive navigation. This is
+ * the conversion's only behavioral guarantee carried over from windowing: an
+ * agent run must survive the user navigating to /memory and back.
+ *
+ * Mechanism — portal container swap: each instance renders through a React
+ * portal into a stable per-workspace container <div>. The container's DOM
+ * parent swaps between a hidden module-level holding element and the chat-tab
+ * slot (`ChatSlot` — the §5.2 seam-b node WorkspaceRoute passes into
+ * WorkspaceDesktopApp's `chatSlot` prop) whenever /workspaces/:id/chat is
+ * active. Re-parenting a portal container moves DOM without remounting the
+ * React subtree, so component state, timers and SSE streams are preserved.
+ *
+ * Stage C mounts this with a one-liner inside AppShell's <main>: <ChatHost />.
+ * ChatWindowInstance props are byte-identical to Desktop.tsx:341-358, sourced
+ * from useChatWidgetState + ShellContext (§4.2); the window's stamped
+ * workspaceName/templateLabel resolve live from the workspaces list instead.

+/**
+ * RouteTransition — the DEFAULT motion tier for top-level route changes
+ * (path-to-9 Pillar 1.1 · Lane RT). Wraps the AppShell `<Outlet/>` in a
+ * fade-through crossfade with PERSISTENT chrome (the sidebar + StatusBar live
+ * OUTSIDE this subtree in AppShell, so they never fade). NOT a global router
+ * rewrite — the router is untouched; this only reshapes what renders into the
+ * shell's single canvas.
+ *
+ * Design contract:
+ *  1. DEFAULT crossfade, keyed by ROUTE GROUP (top path segment — see
+ *     routeGroupKey), so a workspace sub-tab change never crossfades the whole
+ *     surface; only a top-level surface change (home→memory→settings…) does.
+ *     Enter/exit = opacity fade (DUR.base + EASE_OUT).
+ *  2. Interruptibility + input-primacy (ACCEPTANCE): `mode="popLayout"` (never
+ *     "wait") so an exit NEVER blocks the next enter — a route change
+ *     mid-transition redirects immediately; the final route always wins.
+ *  3. Focus + assistive-tech, shipped INSIDE this component: on a group change
+ *     the exiting panel is set `inert`+`aria-hidden` (focus / the SR virtual
+ *     cursor can never land in it), focus moves to the destination surface's
+ *     primary heading (or the panel landmark), and the route is announced via a
+ *     polite live region.
+ *  4. Reduced-motion (REDUCED.routeTransition): no opacity animation — an
+ *     instant swap; focus + announce still fire.
+ *  5. Feature-flagged (routeTransitionEnabled) — OFF renders the bare outlet,
+ *     the exact pre-Lane-RT behaviour, so a regression is one flag flip.
+ *
+ * ChatHost is deliberately NOT wrapped (it is a sibling in AppShell) — it keeps
+ * in-flight SSE alive across route changes; wrapping it here would remount it.

+ *  - Rows render via the ConnectorCard DS piece (§14.7 states + lastSyncAt).
+ *  - §8a consumption switch: shared ConnectorDefinition replaces the local
+ *    thin Connector duplicate; categories come from the shared `category`
+ *    field, not a hardcoded id map.
+ *  - New actions: Sync now (C16 health probe + stamp — honest copy, not a data
+ *    re-pull), Revoke (C17 strong path w/ scope-and-consequence confirm incl.
+ *    the shared-Google-token-pair warning) distinct from the lighter

+/**
+ * MCPHubApp — standalone MCP Hub (UX-Refactor Phase 4B, S08; PRD §12.8 "MCPs
+ * are powerful but always visible, scoped, auditable, and reversible").
+ *
+ * Tabs: Installed · Catalog · Custom · Remote Registry · Activity.
+ *  - Installed: live instances from GET /api/mcps (state badges, start/stop,
+ *    C21 test with the live/static mode label, C19 scope editor, revoke with
+ *    a scope-and-consequence confirm). Logs = honest coming-soon (no route).
+ *  - Catalog: the static registry grid (McpCatalog) wired to the real
+ *    installer — PRO+ (B5; 403 routes through the UpgradeModal) and the
+ *    SecurityGate "risk approval required" path renders the ApprovalModal
+ *    (HIGH findings can be force-overridden; CRITICAL never).
+ *  - Custom: register an arbitrary stdio server (PRO+ server-side).
+ *  - Remote Registry: C20 deferred — static catalog pointers only, the
+ *    runtime is stdio-only in v1.
+ *
+ * Note on the PRD §12.8 five-tab vocabulary: the "Marketplace" tab is
+ * deliberately NOT duplicated here — Phase 4A deferred the marketplace
+ * consolidation to the single S21 surface (MarketplaceApp), which the dock's
+ * Extend zone exposes next to this hub.

+ * survive as secondary tabs after a divider — capability preserved, entry
+ * restructured. Mind pills render only on the Memories tab: the legacy tabs
+ * keep their own scoping (Graph has a scope selector; Harvest writes to the
+ * personal mind by design).
+ *
+ * Controlled component (the ratified WorkspaceDesktopApp two-seam pattern):
+ * the route owns mind + view via URL (`/memory/:mindScope?` + `?tab=`); this
+ * component only renders and reports intent via onMindChange/onViewChange.
