+# bitvid First-Run Experience (Onboarding) — Plan
+
+Goal: escort fresh logins through the tool with a guided, skippable tour —
+spotlight + accent-glow highlights, popover explanations — and route them into
+the two setup flows that unlock the product (storage for uploading, NWC for
+zapping). All state is local (static client, no backend).
+
+## Locked decisions (2026-07-02, maintainer approved)
+
+1. **Hand-rolled tour engine, no dependency** (`js/ui/onboarding/tourEngine.js`).
+   Spotlight = one scrim element whose huge `box-shadow` dims everything except a
+   cutout over the anchor; an `::after` ring pulses with `--color-accent` /
+   `--color-accent-strong` (theme-aware glow). Positioning via CSS custom
+   properties set from JS (`style.setProperty` — the codebase's sanctioned
+   pattern); all visuals in an injected stylesheet using design tokens only.
+2. **Anchors reuse existing stable selectors** (`data-testid` added for e2e +
+   sidebar ids). Steps whose anchor is missing in the current layout are skipped
+   automatically, so one script serves desktop + mobile.
+3. **Once per pubkey per device** (`bitvid:onboarding:v1` map in localStorage —
+   same shape as `settingsRestorePrompt`'s offered-flags). Fully skippable
+   (Skip button, Esc), keyboard navigable (arrows), and **re-launchable** from
+   the profile modal footer ("Take the tour", `force: true`).
+4. **Trigger**: 3.5s after login (feed rendered thanks to the warm cold-boot
+   work; the settings-restore prompt's 2s window — which only fires for accounts
+   with synced settings, i.e. NOT first-run users — has passed). Never blocks
+   login.
+5. **Final card = setup CTAs**: "Set up storage" / "Connect wallet" deep-link
+   into the profile modal panes (`profileController.show("storage"|"wallet")`).
+
+## Phases
+
+- **Phase 1 (BUILT)**: tour engine + spotlight/glow CSS, bitvid step script
+  (welcome → feeds → subscriptions → upload → profile → setup CTAs), first-login
+  trigger, per-pubkey flag, "Take the tour" relaunch button.
+- **Phase 2**: "Getting started" checklist card (verify relays ✓, follow 3
+  channels ✓, set up storage ✓, connect wallet ✓, first upload ✓) — persistent
+  and dismissible; catches users who skip the tour.
+- **Phase 3**: empty-state upgrades — every empty feed/pane teaches + CTA
+  (suggested channels from trust seeds in an empty For You / Subscriptions).
+- **Phase 4**: fresh-npub bootstrap — hook the existing `generate` auth provider
+  into a "Create account" flow with a REQUIRED key-backup step, then inline
+  kind-0 profile setup (name + avatar), then the tour.
+
+## Non-goals
+
+- No server-side anything (static client rule).
+- No tour analytics/telemetry.
+- The tour never performs actions for the user — it points and deep-links only.

 ### 52. After editing a video, the video grids don't refresh to show the update (BUG)
-- [ ] Editing a video leaves the grids showing the pre-edit version until a manual
-      reload. Publishing a NEW video already refreshes the feed (**#46**); the **edit**
-      path needs the same post-publish grid refresh (title/thumbnail/description/url).
-      Likely wire the edit-submit success into the same `refreshAllVideoGrids` /
-      `onVideosShouldRefresh` path #46 uses, keyed by `videoRootId`.
+- [x] **FIXED 2026-07-02.** The edit flow already re-ran `loadVideos()`, but the cache
+      still held the PRE-edit version: unlike new publishes (#46), the edit never
+      ingested its signed replaceable event locally, so grids re-rendered stale until
+      relays echoed the update. `nostrService.handleEditVideoSubmit` now ingests the
+      edited event via `ingestLocalVideoEvent` (newest-wins replace in the active
+      store + `videos:updated`), so grids show the new title/thumbnail/etc.
+      immediately. Test: `tests/services/nostr-service.test.mjs` (+1).

+- [x] **Phase 1 BUILT 2026-07-02.** Guided tour for fresh logins: spotlight scrim
+      with a cutout over each step's anchor + a pulsing accent-glow ring
+      (`--color-accent`/`--color-accent-strong` theme tokens), anchored popover with
+      Back/Next/Skip + progress dots, keyboard nav (arrows/Esc). Hand-rolled engine
+      (`js/ui/onboarding/tourEngine.js`, no deps) positioning via CSS custom
+      properties; steps with missing anchors auto-skip (responsive-safe). Steps:
+      welcome → feeds (#sidebar) → subscriptions → upload → profile → final card with
+      "Set up storage" / "Connect wallet" deep-links into the profile panes. Offered
+      once per pubkey per device (`bitvid:onboarding:v1`, settingsRestorePrompt-style
+      flags), triggered 3.5s after first login, re-launchable via "Take the tour" in
+      the profile modal footer. Tests: `tests/onboarding-tour.test.mjs` (5).
+- [ ] **VERIFY on unstable:** log in with a pubkey that has never completed the tour
+      → tour appears ~3.5s after the feed renders; spotlight glow follows each anchor;
+      Skip/Esc dismisses and never re-offers; "Take the tour" replays it; the final
+      card's buttons open the storage/wallet panes.

+      storage ✓, wallet ✓, first upload ✓) — persistent + dismissible.

+      seeds in empty For You / Subscriptions).
