+# BitVid Bridge — cross-platform streaming helper app — Dev Plan
+
+Companion to **`docs/live-publish-plan.md`** (#16c) — this expands its **Phase 7
+(Local Bridge app)** into its own plan. The Bridge is the piece that fills the one
+gap a static web client can't: **receiving and routing live media** on the
+creator's machine.
+Status: **FUTURE / exploratory — all design decisions LOCKED** (maintainer
+accepted every recommendation), but **DELIBERATELY DEFERRED** — see the priority
+principle below.
+
+> **⛔ PRIORITY PRINCIPLE — static bitvid first (maintainer).** Put as much effort
+> into the **static bitvid client** as possible before branching into any *separate
+> application*. The Bridge is a second app (own repo, toolchain, cross-platform
+> packaging, code-signing cost), so **do not start it** until the static client's
+> live features have shipped and are maximally developed — specifically the Go-Live
+> **Tier-1/2 MVP** (external-provider + serverless, zero infra; see the publish
+> plan's provider spectrum). Rule of thumb: **exhaust what the static client can do
+> before writing a second app.** Build the Bridge only once live has shipped *and*
+> shown real demand for the sovereignty/power features it adds (local recording +
+> full-WebTorrent VOD, no-third-party, multi-restream, hardware/appliance, capture).
+
+Goal (maintainer, *when it's time*): a **super-simple, easy-to-install,
+easy-to-use** cross-platform app (Windows / macOS / Linux) that makes going live on
+bitvid turnkey.
+
+---
+
+## Core decision
+
+The Bridge is a **local media receiver + router**, not a Nostr identity holder.
+It pairs a **native media core** (receive/record/restream/upload) with an
+**embedded bitvid "Studio" webview** that does all Nostr signing. The two stay
+logically separated inside one app:
+
+```
+BitVid Bridge (one installable app)
+├── Native media core  → RTMP/SRT/WHIP ingest, HLS/WebRTC out, record, restream,
+│                         S3 upload   (never sees the Nostr key)
+└── Embedded Studio webview → bitvid client that signs NIP-53 + publishes VOD
+                              (talks to the core over in-app IPC, not localhost HTTP)
+```
+
+**Why an embedded webview instead of "the website controls a localhost server":**
+it solves two hard problems at once —
+1. **No browser↔localhost pain.** An HTTPS page calling `http://127.0.0.1` hits
+   mixed-content + Private-Network-Access preflight/permission rules. In-app IPC
+   (Tauri commands / Wails bindings) sidesteps all of it.
+2. **Signing stays in the web layer.** The webview is a bitvid client, so it signs
+   exactly as the browser does; the native core never touches the key. This
+   honors the publish plan's Rule 1 ("BitVid signs; Bridge routes") while still
+   being one self-contained app.
+
+**Where the Bridge sits (see the publish plan's three-tier provider spectrum):**
+- **Tier 1 (platform embed)** and **Tier 2 (serverless RTMP→HLS: Livepeer/Mux/
+  Cloudflare)** need **no Bridge and no VPS** — Tier 2 is the recommended
+  "no-server, native playback" default. So the Bridge is the **Tier-3 (advanced /
+  full-sovereignty)** option, not the default on-ramp.
+- **The Bridge earns its place** by: no third party at all, **local recording +
+  full-WebTorrent VOD**, multi-restream hub, hardware/appliance input, turnkey UX,
+  and later built-in capture (no OBS).
+
+**Hybrid that avoids a VPS entirely (important):** a **local** Bridge can
+**record locally + restream to a Tier-2 serverless provider** which serves the
+public HLS. The home Bridge then **never needs to be publicly reachable** (no VPS,
+no tunnel/port-forward — it's *outbound* to the provider), yet the creator still
+gets local recording + a full-WebTorrent VOD, and viewers get native HLS. This is
+the sweet spot for most sovereignty-minded creators: **local Bridge for
+record/WebTorrent/control + serverless for reach.**
+
+---
+
+## Decisions — ✅ ALL LOCKED
+
+The maintainer accepted every recommendation below; each *Recommendation* line is
+now the **locked choice**. Summary:
+
+| # | Decision | Locked |
+|---|----------|--------|
+| 1 | App framework | **Wails (Go)** — one Go binary for desktop + headless node (ties to D7); Tauri was the close alt |
+| 2 | Control model | **Embedded Studio webview** primary; optional localhost API later |
+| 3 | Capture vs receive | **Receiver-first MVP**; built-in capture as a fast-follow (Phase 5) |
+| 4 | Webview signer | **NIP-46 + encrypted-nsec**, NIP-46 preferred |
+| 5 | Ingest protocols | **RTMP for MVP**; SRT + WHIP later |
+| 6 | Recording upload | **Bundled rclone** (multi-provider, resumable) |
+| 7 | One codebase, two modes | **Yes** — desktop Bridge == self-hosted Media Node run `--headless` |
+| 8 | Transcode | **Pass-through only** (`-c copy`) |
+| 9 | Code signing | **Project owns** Apple notarization + Windows cert (budgeted) |
+| 10 | License / telemetry | **Match bitvid; no telemetry by default** |
+
+D1 resolves to **Go/Wails** specifically because D7 (one codebase, two modes) is a
+"yes": a single Go binary serves the desktop Bridge (with UI) and the headless
+self-hosted Media Node — Go being MediaMTX's own language makes that clean.
+
+> **DECISION 1 — App framework.** Go/**Wails** vs **Tauri** vs Electron.
+> *Recommendation: **Wails (Go)** or **Tauri (Rust)** — both give a web UI (reuse
+> bitvid's components/tokens) and small binaries; Electron is ~100MB+ and heavy,
+> against "simple install." Slight lean **Wails/Go**: the media stack is Go-native
+> and **MediaMTX is written in Go**, so it's one language, one small static binary,
+> trivial cross-compile. Tauri is a very close second with a more mature app-shell
+> + updater. Pick based on team comfort (Go vs Rust).*
+
+> **DECISION 2 — Control model.** Embedded Studio webview (self-contained app) vs
+> website-drives-localhost-API vs both.
+> *Recommendation: **embedded webview primary** (dodges PNA/mixed-content + keeps
+> signing in the web layer). Optionally expose a **localhost API later** for people
+> who want to drive it from the bitvid website (with the PNA/CORS work done then).*
+
+> **DECISION 3 — Capture vs receive.** MVP receives (OBS/hardware → Bridge) vs push
+> built-in screen/camera capture earlier.
+> *Recommendation: **receiver-first MVP** — works with the OBS/encoders people
+> already have and ships fast. **Built-in capture (no OBS)** is the "super simple"
+> headline but is effectively a mini-OBS (encoder is hard) → make it a fast-follow
+> phase, not MVP.*
+
+> **DECISION 4 — Signer support in the Bridge webview.** Since the webview signs,
+> which login methods? **NIP-46 remote signer** (no key on device — safest), the
+> **encrypted-nsec** flow the web app already has (key encrypted on-device), or
+> both. NIP-07 extensions generally aren't available inside an app webview.
+> *Recommendation: **both NIP-46 + encrypted-nsec**, NIP-46 preferred/first. Reuse
+> the web app's existing session/signer code so there's nothing new to audit.*
+
+> **DECISION 5 — Ingest protocols for MVP.** RTMP only, or RTMP + SRT + WHIP.
+> *Recommendation: **RTMP for MVP** (universal — OBS/hardware all speak it), add
+> **SRT** (better over lossy networks) and **WHIP** (WebRTC ingest, low latency)
+> in a later phase. MediaMTX supports all three, so it's mostly UI/config.*
+
+> **DECISION 6 — Recording upload mechanism.** Bundle **rclone** (one binary,
+> speaks R2/B2/S3/MinIO + resumable) vs a native S3 SDK in the core vs reuse
+> bitvid's browser S3 upload from the webview.
+> *Recommendation: **rclone** bundled as a sidecar — dead-simple multi-provider
+> support + resumable uploads of large recordings, matches the storage providers
+> bitvid already supports. Native SDK only if we want to drop the extra binary.*
+
+> **DECISION 7 — One codebase, two modes?** The server-side **Media Node** (#16c)
+> and the local **Bridge** are ~the same thing (MediaMTX + session API + upload +
+> restream). Build **one codebase that runs headless (Media Node) or with the
+> embedded UI (Bridge)?**
+> *Recommendation: **yes** — "self-host the Media Node" (publish-plan DECISION 1b)
+> becomes literally "run the Bridge in `--headless` mode on a VPS." Big reuse win;
+> steers DECISION 1 toward Go (server + desktop from one Go binary).* 
+
+> **DECISION 8 — Transcode.** Pass-through (`-c copy`) only, or offer local
+> transcode profiles?
+> *Recommendation: **pass-through only** (same as the publish plan). Require
+> H.264/AAC in; the Bridge repackages/forwards without re-encoding — keeps CPU low
+> and the app light. Transcoding is a later, opt-in power feature.*
+
+> **DECISION 9 — Code signing + distribution ownership.** "Easy install" *requires*
+> **Apple notarization** (Developer ID — or macOS Gatekeeper blocks it) and a
+> **Windows Authenticode cert** (or SmartScreen scares users). Who holds the certs
+> and pays (~$99/yr Apple + Windows cert)? Linux = AppImage + `.deb`/`.rpm`
+> (no signing gate). *Recommendation: the project owns the certs; budget for them —
+> this is the true cost of "easy to install," not optional.*
+
+> **DECISION 10 — License / telemetry.** Open-source license (match bitvid's) and
+> **no telemetry by default** (opt-in crash reports at most). *Recommendation:
+> same license as bitvid; privacy-first, opt-in only.*

+└── (optional) localhost API          → for website control, later   DECISION 2
+```
+
+- **Studio webview sourcing.** The webview loads the **instance's deployed bitvid
+  web app** (remote URL, cached for offline resilience) rather than a bundled copy.
+  Benefit: it's always current and **auto-inherits the instance's flags** (so
+  `FEATURE_LIVE_PUBLISH` off ⇒ no go-live, invariant 6) with no app update needed;
+  a trimmed bundled fallback covers the offline/first-run case. The instance URL is
+  configurable (a user may use more than one bitvid instance).
+- **Media core = a local Media Node.** Same engine as the server-side node (#16c),
+  which is why DECISION 7 (one codebase, two modes) is attractive.
+- **Stream keys / ingest URLs never leave the device** and never go into Nostr; the
+  webview only ever publishes the *playback* URL.
+- **Status → Nostr:** MediaMTX hooks fire `input_connected / input_live /
+  input_lost / recording_finalized / upload_complete`; the core forwards these to
+  the webview over IPC; the **webview signs** the corresponding NIP-53 update
+  (planned → live → ended + recording).
+
+---
+
+## UX flow (the "super simple" target)
+
+```
+1. Install (signed installer / AppImage).                            DECISION 9
+2. Open app → sign in (NIP-46 or encrypted nsec) in the Studio webview. DECISION 4
+3. Fill title/thumbnail/tags → "Prepare stream" (publishes status=planned).
+4. App shows one of:
+   a. RECEIVE MODE: local ingest URL + key to paste into OBS/encoder.  DECISION 3
+   b. (later) CAPTURE MODE: pick a screen/window/camera → "Go Live".
+5. Encoder connects → core detects input → webview publishes status=live.
+6. (optional) toggle restream outputs (YouTube/Twitch/zap.stream).     DECISION 5
+7. "End" → status=ended → core finalizes recording → uploads → webview
+   offers "Publish recording as a BitVid video" (archive→VOD).
+```
+
+The whole point: **one window, sign in, go live, done** — and the recording
+becomes a normal bitvid video automatically.
+
+---
+
+## Cross-platform packaging
+
+- **Windows:** signed `.msi`/`.exe` (Authenticode). Auto-update.
+- **macOS:** signed **+ notarized** `.dmg` (Developer ID) — mandatory. Universal
+  (arm64 + x86_64).
+- **Linux:** **AppImage** (zero-install portable) + `.deb`/`.rpm`; consider Flatpak.
+- **Bundled binaries per-platform:** MediaMTX, FFmpeg, rclone. FFmpeg is the size
+  hog (~50–80MB) — ship a **minimal build** (only the muxers/protocols we use:
+  flv/rtmp/mpegts/hls/webrtc, aac/h264 passthrough) to keep the installer lean.
+- **Auto-updater** (both Tauri and Wails have one) with signed release artifacts.
+
+---
+
+## Phases
+
+- **Phase 0 — Shell + media core (foundational).** App skeleton (DECISION 1),
+  bundle + supervise MediaMTX, embedded Studio webview, webview↔core IPC, signed
+  dev builds on all three OS. Sign-in works (DECISION 4).
+- **Phase 1 — Receive → serve (the MVP).** Local RTMP ingest → serve HLS. For
+  public viewers the playback origin must be **reachable**, so either run the
+  Bridge **headless on a reachable host** (VPS — the self-hosted node) or
+  copy-forward from a local Bridge to that reachable node / an external provider
+  (never a bitvid-run node). Publish planned→live→ended NIP-53 from the webview via
+  MediaMTX input hooks. "OBS → your node → bitvid, one window."
+  *(NAT note: a home-only Bridge can't serve public HLS directly → either run
+  headless on a VPS, or use the hybrid: forward to a Tier-2 serverless provider
+  that serves public HLS — see Phase 3.)*
+- **Phase 2 — Record → archive → VOD.** Local recording, finalize, rclone upload
+  to the user's storage, manifest → webview publishes a normal bitvid video
+  (reuses the `s`-tag/info.json/30078 flow). Optional torrent/webseed for full
+  WebTorrent VOD.
+- **Phase 3 — Multi-restream (`FEATURE_LIVE_RESTREAM`).** One input → many outputs
+  (YouTube/Twitch/zap.stream/**serverless providers Livepeer/Mux/Cloudflare**/
+  custom RTMP/SRT), copy-only, per-output status + retry/backoff. Keys stay local;
+  optional public mirror links as `r` tags. **The serverless preset enables the
+  no-VPS hybrid** — a local Bridge records locally + forwards to Livepeer/Mux,
+  which serves the public HLS (the `streaming` URL in the NIP-53 event). This is
+  arguably the flagship Bridge workflow for home creators.
+- **Phase 4 — Turnkey UX + packaging.** One-click go-live, OBS auto-config or
+  OBS-WebSocket control, signed/notarized installers + AppImage, auto-update.
+- **Phase 5 — Built-in capture (no OBS).** Screen/window/camera capture + encode
+  inside the app (`getDisplayMedia`/`getUserMedia` → WebCodecs/FFmpeg). The "super
+  simple" headline: go live with no external encoder.
+- **Phase 6 — SRT/WHIP ingest + WebRTC low-latency** (DECISION 5).
+- **Phase 7 — Headless "Media Node" mode + hardware / "BitVid Box".** Run the same
+  binary headless as the self-hosted Media Node (DECISION 7); harden for
+  appliance/headless use — the seed of a physical device.
+
+---
+
+## Engineering rules (invariants)
+
+1. **The native core never sees the Nostr key.** Only the webview signs.
+2. **Ingest URLs/keys stay on the device; only playback URLs reach Nostr.**
+3. **Pass-through first** — copy H.264/AAC, don't transcode (DECISION 8).
+4. **Reuse bitvid's web client** for the Studio webview (session, signer, publish,
+   upload-modal-style VOD flow) — minimize net-new signing/auth code.
+5. **Optional, not required** — a creator can still stream OBS → an external
+   provider without the Bridge; the Bridge *adds* self-hosting + convenience/power
+   (and bitvid never runs a node — blanket rule).
+6. **Respect the connected instance's config.** The embedded Studio webview loads
+   a specific bitvid instance, so it inherits that instance's flags — if the
+   instance has `FEATURE_LIVE_PUBLISH` **off**, the Bridge shows go-live as
+   unavailable for it (nothing to publish to). The Bridge is only useful pointed
+   at an instance that has publishing enabled; surface that clearly rather than
+   failing opaquely.
+7. **Bind the local ingest to loopback only.** The RTMP/SRT receiver listens on
+   `127.0.0.1` (not `0.0.0.0`) by default so it isn't exposed to the LAN;
+   appliance/headless mode (Phase 7) can opt into a wider bind with auth.
+
+---
+
+## Risks / watch-items
+
+- **Code signing is the real "easy install" cost (DECISION 9).** Apple
+  notarization + Windows cert are non-negotiable for a frictionless install and
+  cost money + setup. Budget for them up front.
+- **Bundle size vs simplicity.** MediaMTX + FFmpeg + rclone add up; a minimal
+  FFmpeg build and per-platform packaging keep it reasonable, but it won't be
+  tiny. Trade-off vs "super light."
+- **Built-in capture is a mini-OBS (DECISION 3/Phase 5).** Reliable capture +
+  encode across GPUs/OSes is genuinely hard — don't let it block the receiver MVP.
+- **Signing during long streams.** Same issue as the publish plan (DECISION 2
+  there): the webview must stay running to sign status updates + heartbeats;
+  handle sleep/crash gracefully (NIP-53 treats no-update-in-~1h as ended).
+- **Webview signer support.** NIP-07 extensions typically aren't present in an app
+  webview → lean on NIP-46 / encrypted-nsec (DECISION 4).
+- **Encoder compatibility.** Pass-through needs H.264/AAC + sane keyframes;
+  detect + warn on incompatible input rather than failing silently.
+- **Scope creep.** This app can sprawl (capture, transcode, appliance). Ship the
+  receiver MVP (Phase 0–1) first; everything else is additive.
+- **Instance without publishing enabled.** If a user points the Bridge at an
+  instance that has `FEATURE_LIVE_PUBLISH` off, go-live must degrade gracefully
+  (clear "publishing isn't enabled on this instance" state), not error obscurely
+  (invariant 6).
+- **Local ingest exposure.** A misconfigured wide bind would expose an unauth'd
+  RTMP receiver on the network — default to loopback (invariant 7); require auth
+  for any non-loopback bind.
+- **Reachability / NAT (self-hosting reality) — largely solved by the hybrid.** A
+  **home-only Bridge behind NAT can't *serve* public HLS**. Two clean answers:
+  (1) the **hybrid** — the local Bridge *forwards* (outbound) to a Tier-2
+  serverless provider that serves the public HLS, so the home box needs no public
+  reachability at all (recommended for laptops/home); (2) run the Bridge
+  **headless on a reachable VPS** for full self-hosting (no third party). Only (2)
+  needs a VPS; document both. This is why headless mode (Phase 7 / DECISION 7) and
+  restream-to-serverless (Phase 3 preset) both matter.

+# Live Streams — INGEST / watch-only — Dev Plan
+
+TODO ref: **#16** in `todo/TODO_2026-06-20_pre-launch.md` (watch-only).
+Publishing / "Go Live" is **#16c** — a separate, larger effort with its **own**
+config flag; it is explicitly **out of scope** for this doc.
+Status: **DECISIONS LOCKED (D1–D5)** — Phase 0 research spike first (confirm tag
+shapes + hls.js/CORS + default relays), then build. Not started.
+
+Live streams are **NIP-53 Live Activities** — a *different* NIP from short-form
+video (#16b / NIP-71). Kind **30311** is the live event (addressable, carries the
+`streaming` URL — usually HLS `.m3u8` — plus `status`, title, host `p` tags);
+kind **1311** is live chat. zap.stream and shosho.live publish these.
+
+Scope of this feature: **discover live streams, play the HLS stream, chat
+(read → post, phased), and zap the host.** No broadcasting, no media hosting.
+Everything ships behind a config flag that leaves **no trace** when off.
+
+---
+
+## Decisions needed
+
+> **DECISION 1 — Listing scope. ✅ LOCKED: Option A (whitelisted hosts only).**
+> The Live tab lists only kind-30311 events whose host is a whitelisted/trusted
+> author, reusing the existing whitelist/WoT filter — no new moderation surface,
+> consistent with the main feed + Shorts. Accepted trade-off (maintainer): live
+> is sparse, so the tab may be empty when no whitelisted creator is streaming;
+> that's expected with a whitelist (ship a clear "no one you follow is live right
+> now" empty state). A broader "discover live" surface can come later.
+
+> **DECISION 2 — Chat level. ✅ LOCKED: read + post + zaps as the end state,
+> reached in phases.** Target is full participation (read chat, post chat, zap the
+> host). Phased so playback ships first and posting (a write path) lands cleanly:
+> - **Phase 3** — read-only kind-1311 chat **+ host zaps** (zaps via the existing
+>   NWC/zap system; active participation from day one of chat).
+> - **Phase 3b** — **post chat**: sign/publish kind-1311 into the stream, behind
+>   its own sub-flag (`FEATURE_LIVE_CHAT_POST` or similar), with a moderation
+>   stance (rate-limit; you're publishing into someone else's stream — decide how
+>   blocked/muted authors and your own outbound spam are handled).
+> Rationale (maintainer): end up at read+post+zaps; phasing keeps the write path
+> and its moderation questions out of the initial playback release.
+
+> **DECISION 3 — HLS playback dependency. ✅ LOCKED: Option A (hls.js,
+> lazy-loaded behind the flag).** Native `<video>` HLS only works in Safari, so a
+> library is required for Chrome/Firefox/Edge; hls.js is the mature standard.
+> Maintainer deferred to recommendation. Implementation guardrails:
+> - **Vendored**, not a runtime CDN import (bitvid ships assets locally; keeps it
+>   working offline/self-hosted and avoids a third-party origin dependency).
+> - **Dynamically imported only when the live player opens** — never loaded when
+>   `FEATURE_LIVE_INGEST` is off (honors "off = no trace"), and not on the
+>   critical path for non-live pages.
+> - Prefer native HLS where available (Safari) and fall back to hls.js elsewhere,
+>   so Safari users don't pay for the library.
+> - Precedent: bitvid already ships WebTorrent (a much heavier dep), so one small
+>   well-established HLS lib is proportionate.
+
+> **DECISION 4 — Past streams / VOD presentation. ✅ LOCKED: Option A (one Live
+> tab: live first, then recent ended).** Currently-live streams sort to the top;
+> recently-ended streams follow, clearly badged "Ended" and playing their
+> `recording` VOD (normal scrubber) through the same HLS path. Bonus: this
+> **mitigates the sparse-live empty-tab concern from DECISION 1** — a whitelisted
+> creator's recent past streams keep the tab populated between live sessions.
+> A separate "Past streams" section only if the single list gets crowded.
+
+> **DECISION 5 — Discovery relays. ✅ LOCKED: Option B (user read relays + a
+> configurable set of live-discovery relays).** Query kind-30311 on the user's
+> read relays PLUS a small instance-config list of known stream relays
+> (default a couple of well-known ones, e.g. zap.stream's relay; editable per
+> deployment). Widens *where* we look without widening *who* — DECISION 1's
+> whitelist still gates the hosts shown. Extra relays are only connected when
+> `FEATURE_LIVE_INGEST` is on, capped/deferred per the relay-storm invariants.
+> Phase 0 confirms which stream relays to ship as defaults.
+
+---
+
+## Config flags (off = no trace)
+
+Flags introduced by this doc (both default `false`, threaded through
+`js/config.js` → `js/constants.js` like `FEATURE_NIP71_INGEST`):
+- **`FEATURE_LIVE_INGEST`** — the whole watch-only feature (tab, discovery,
+  playback, read chat, host zaps).
+- **`FEATURE_LIVE_CHAT_POST`** — the Phase 3b write path (posting chat); only
+  meaningful when ingest is also on. Kept separate so an instance can allow
+  watching + reading chat without enabling outbound posting.
+
+(The `FEATURE_LIVE_PUBLISH` "Go Live" flag belongs to **#16c**, a separate doc.)
+
+When `FEATURE_LIVE_INGEST` is off, all of the following must be absent:
+1. **Sidebar tab** — the "Live" link is not rendered in `components/sidebar.html`.
+2. **Feed/view registration** — `FEED_TYPES.LIVE` is not registered.
+3. **Subscriptions** — no kind-30311 discovery subscription and no kind-1311 chat
+   subscription are ever created.
+4. **Route** — `#view=live` falls back to the default view.
+5. **HLS library** — hls.js is dynamically imported only inside the live player,
+   so it never loads when the flag is off (keeps the bundle/network clean).
+6. **Chat-post UI** — the compose box (Phase 3b) is absent unless BOTH
+   `FEATURE_LIVE_INGEST` and `FEATURE_LIVE_CHAT_POST` are on.
+7. **Config surface** — the flags above are the only footprint.
+
+> **Management UI note:** a **"Live" sub-tab in profile → My Videos** (alongside
+> Videos / Shorts, reusing the admin sub-tab pattern) is for managing the user's
+> OWN streams — so it belongs to **publishing (#16c / `FEATURE_LIVE_PUBLISH`)**,
+> not this ingest feature. With ingest-only enabled there is nothing of the user's
+> to manage, so no My-Videos Live sub-tab appears. (See the shorts plan's
+> "Publish & management UI" section for the shared sub-tab treatment.)
+
+---
+
+## Field mapping — kind 30311 (to VERIFY in Phase 0)
+
+Expected tag shape (confirm against captured real events before building):
+
+| Tag | Purpose |
+|-----|---------|
+| `d` | unique identifier (addressable key with pubkey+kind) |
+| `title` / `summary` | stream title / description |
+| `streaming` | **HLS `.m3u8` playback URL** (may appear more than once) |
+| `recording` | VOD URL when ended |
+| `status` | `planned` / `live` / `ended` |
+| `starts` / `ends` | unix timestamps |
+| `image` | thumbnail/poster |
+| `p` (role `host`/`participant`) | host + participants (pubkeys) |
+| `service` | provider hint (zap.stream etc.) |
+| `current_participants` / `total_participants` | viewer counts (optional) |
+
+Kind 1311 (live chat): a note tagged with the 30311 `a`-address; content is the
+chat message. Read-only ingest = subscribe by `#a`, render newest.
+
+> These are the *documented* shapes; **Phase 0 captures real events** from
+> zap.stream and shosho.live to confirm exact keys, multiplicity of `streaming`,
+> and how each provider marks live vs ended.
+
+---
+
+## Architecture
+
+- **Flag:** `FEATURE_LIVE_INGEST` (instance-config → config → constants).
+- **Feed type:** add `LIVE: "live"` to `FEED_TYPES` (`js/constants.js`).
+- **Discovery source:** a new live service (e.g. `js/services/liveIngestService.js`)
+  subscribing to kind 30311 (`status=live`, scoped per DECISION 1), normalizing
+  events into a lightweight "live card" model (title, host, image, streaming URL,
+  status, viewer count). Mirrors the deferred/throttled pattern of
+  `nip71IngestService` so it stays off the cold-start critical path.
+- **Sidebar tab + view:** "Live" link in `components/sidebar.html` (flag-gated) +
+  `views/live.html` (grid of live cards).
+- **Card design (new):** a **live card** distinct from `VideoCard.js` — a **LIVE
+  badge**, viewer count, host name/avatar, and an "ended" state for past streams
+  (Phase 4). Likely a dedicated `LiveCard` (the live/ended metadata differs enough
+  from a video card that a variant is awkward). New `data-testid` for e2e.
+- **Player:** a live player path. The current player
+  (`js/services/playbackService.js`) sets `videoEl.src` for URL/WebTorrent; HLS
+  needs hls.js attached to the `<video>` element when the source is `.m3u8`
+  (native only on Safari). Lazy-load hls.js on first live play (DECISION 3).
+- **Chat (DECISION 2):** read-only kind-1311 subscription by `#a` (Phase 3),
+  rendered beside the player with WoT-mute filtering; a compose/post path in
+  Phase 3b behind `FEATURE_LIVE_CHAT_POST`; teardown on close.
+- **Liveness/staleness:** an event with `status=live` but no recent update / dead
+  `.m3u8` should be de-emphasized or dropped (see Risks).
+
+---
+
+## P2P-assisted playback (future — bitvid's bandwidth edge)
+
+Q: "Can live use WebTorrent?" **Classic WebTorrent can't carry a *live* stream** —
+a torrent's infohash is computed from the *complete* file, and live content
+doesn't exist yet. bitvid's WebTorrent is progressive playback of a finished VOD,
+not live. **But P2P *live* is real** via a different mechanism: **HLS + peer-to-peer
+segment sharing.** hls.js loads segments while a WebRTC swarm shares them among
+concurrent viewers, so the origin serves each segment fewer times.
+
+- **Concrete stack:** [P2P Media Loader](https://github.com/novage/p2p-media-loader)
+  — hls.js-compatible, and historically used **WebTorrent trackers** for peer
+  discovery. It's a drop-in segment engine for the Phase-2 hls.js player: the
+  "WebTorrent-flavored" path for live.
+- **bitvid advantage:** every extra concurrent viewer helps *serve* the stream
+  instead of only consuming origin bandwidth — cutting the Media Node's egress
+  (the biggest cost/risk of #16c) and matching bitvid's P2P ethos.
+- **Why NOT v1:** P2P offload only pays off with **enough concurrent viewers of
+  the same stream**. DECISION 1 scopes live to whitelisted hosts → likely
+  low-concurrency/sparse, where a swarm adds complexity + a little latency (on top
+  of HLS's 6–30s) for little gain. **v1 = plain hls.js; add P2P-assisted HLS
+  later, gated on real concurrency.**
+- **VOD keeps full WebTorrent:** once a stream ends, its recording is an ordinary
+  bitvid video (complete file → infohash) and gets the normal seed/webseed
+  treatment (see the publish plan's archive→VOD flow).
+
+---
+
+## Live watch UX best practices (researched July 2026)
+
+Unlike shorts, live is a **landscape 16:9, "cinematic"** experience, and the watch
+page is a well-established pattern (Twitch / YouTube Live). Sources at the bottom.
+
+### Desktop presentation (cinematic)
+- **Player + chat side rail.** 16:9 player on the left/center, a **collapsible chat
+  rail on the right**. Below the player: title, **host (avatar + name + follow/
+  subscribe)**, **LIVE badge + viewer count**, elapsed time, description/tags.
+- **Theater mode** (player widens, chat stays docked) and **fullscreen** (chat
+  becomes an optional overlay or hides) — both standard viewer expectations.
+- Keyboard: **Space** pause, **F** fullscreen, **T** theater, **M** mute.
+
+### Mobile presentation
+- **Player on top (16:9), chat below** in a scrollable panel. In landscape /
+  fullscreen, chat becomes a **resizable/draggable overlay** (the current Twitch/
+  YouTube mobile pattern) rather than eating the video. Picture-in-picture
+  "keep playing while I browse" is a nice-to-have, not v1.
+
+### Live-specific affordances
+- **Prominent red LIVE badge + viewer count** (from 30311 `current_participants`)
+  and elapsed-since-`starts`. These are retention cues, keep them visible.
+- **Latency is real and must be expected:** standard **HLS is ~6–30s behind**
+  real-time (LL-HLS 1–5s, WebRTC <500ms). zap.stream serves HLS, so **chat will
+  run ahead of the video** — don't promise low-latency, and don't try to hard-sync
+  chat to the frame.
+- **Auto-scrolling chat** that **pauses when the user scrolls up**, with a
+  "jump to latest" affordance (Phase 3).
+- **Live vs ended seeking:** a live stream has only edge/limited seeking; an
+  **ended stream plays its `recording` as a normal VOD** with a full scrubber
+  (Phase 4).
+
+### bitvid-specific notes
+- **Zaps fit live perfectly** — zap.stream's whole model is zapping streamers, and
+  bitvid already has the NWC/zap system. Live zaps to the host are a natural
+  headline action (surface them alongside chat). Even if chat is read-only in
+  Phase 3, zapping the host can ship earlier. **Zap target:** resolve from the
+  host's profile `lud16`/LNURL, or a zap tag on the 30311 event if present
+  (confirm in Phase 0); reuse the existing zap flow — no new payment code.
+- Reuse the existing player shell where practical; HLS via lazy hls.js (DECISION 3).
+- Respect `prefers-reduced-motion` and the relay-cap / circuit-breaker invariants
+  for the discovery + chat subscriptions.
+
+## Phases (each flag-gated from day one)
+
+- **Phase 0 — Research spike (do FIRST, small but essential).**
+  - Capture real kind-30311 events from zap.stream + shosho.live; confirm tags,
+    `streaming` multiplicity, live/ended marking, host `p` roles.
+  - Prototype HLS playback in a throwaway page: hls.js attaching to `<video>`
+    with a real `.m3u8`; confirm CORS behavior from the static origin.
+  - Pick the default **live-discovery relays** (DECISION 5) from where real
+    30311 events actually land; resolve the **host zap target** (lud16/LNURL vs a
+    `zap` tag on the event).
+  - Output: **confirm** the field mapping + defaults (decisions are already
+    locked); flag any surprises back into this doc.
+- **Phase 1 — Discovery + Live tab (medium).** Flag, `FEED_TYPES.LIVE`, live
+  service (30311 discovery, scoped), sidebar link, `views/live.html`, grid of
+  live cards, route gated by flag. Clicking a card opens… (Phase 2).
+- **Phase 2 — HLS playback + cinematic layout (medium).** Live player path + lazy
+  hls.js; play the `streaming` URL; **desktop** player + collapsible chat rail
+  (rail empty until Phase 3), theater/fullscreen, LIVE badge + viewer count;
+  **mobile** player-top / chat-below; keyboard controls; graceful error when the
+  stream is down. Set latency expectations (HLS ~6–30s).
+- **Phase 3 — Read chat + host zaps (medium, DECISION 2).** Read-only kind-1311
+  subscription by `#a`, auto-scroll with pause-on-scroll-up + jump-to-latest,
+  teardown on close. **Host zaps** via the existing NWC/zap system (active
+  participation from the start).
+- **Phase 3b — Post chat (medium, DECISION 2).** Sign/publish kind-1311 into the
+  stream, behind its own sub-flag, with a moderation stance (rate-limit; how
+  blocked/muted authors + outbound spam are handled). This is the committed end
+  state (read + post + zaps).
+- **Phase 4 — Past streams / VOD (medium, DECISION 4).** List `status=ended`
+  events and play their `recording` URL through the same HLS player; mark ended
+  vs live in the UI. This is the "past zap.stream streams" capability.
+- **Phase 5 — Polish.** Poster/skeleton states, liveness de-emphasis for stale
+  events, high-volume-chat buffering, and (optional) surfacing `planned`/upcoming
+  streams.
+
+---
+
+## Moderation, whitelist & NSFW
+
+Per DECISION 1 (locked: whitelisted hosts): the live list is scoped to
+whitelisted authors and reuses the existing trust filter, so the admin
+whitelist/blacklist governs which streams appear.
+
+**Chat moderation (two design items, before their phases):**
+- **Read chat (Phase 3):** kind-1311 messages come from *arbitrary* viewers, not
+  just whitelisted authors. Decide whether the read view applies the existing WoT
+  **mute/blacklist** (hide messages from muted/blocked pubkeys) — recommend yes,
+  reuse the same author filter so a globally-blocked spammer is hidden in live
+  chat too. NSFW/text moderation of chat is out of scope for v1.
+- **Post chat (Phase 3b):** you're publishing into someone else's stream — add
+  rate-limiting and respect the host/relay's own rules; decide the outbound stance
+  (e.g. block posting for lockdown/blacklisted local users).
+
+---
+
+## Risks / watch-items
+
+- **HLS is new to the player.** Native `.m3u8` works only in Safari; Chrome/
+  Firefox need hls.js. This is the main build risk — de-risk in Phase 0.
+- **CORS on external streaming servers.** The `.m3u8` + segments are served by a
+  third-party origin; playback in a static site depends on their CORS. Verify in
+  Phase 0 (same class of constraint as the storage/edge CORS work).
+- **Stale "live" events.** Streams end without always updating `status`; a dead
+  `.m3u8` must fail gracefully and ideally be filtered. Needs a liveness signal
+  (recent update time / probe).
+- **Relay fan-out.** A live-discovery subscription adds REQ load — respect the
+  cold-login relay-cap / circuit-breaker invariants (AGENTS.md §17); keep it
+  deferred and capped like nip71 ingest.
+- **Scope creep into #16c.** Keep this strictly watch-only; broadcasting is a
+  separate flag + plan.
+- **High-volume chat.** A busy stream's kind-1311 can arrive fast; the read view
+  must cap/virtualize the message buffer (drop-oldest) so it can't balloon memory
+  or jank the UI. Tie into the auto-scroll/pause behavior.
+- **`status=planned` (scheduled) streams.** 30311 supports a not-yet-live state.
+  v1 shows only live + ended (DECISION 4); decide later whether to surface
+  "upcoming" (with `starts`). Just don't let a `planned` event render as if live.
+- **Multiple `streaming` renditions.** `streaming` may appear more than once
+  (quality variants) or point at a master playlist. Pick one sensibly (hls.js
+  handles master playlists); confirm shapes in Phase 0.
+- **Private/token-gated streams.** Only public HLS is in scope — a stream whose
+  `.m3u8` requires auth/tokens is treated as "can't play," gracefully.

+# BitVid Live — PUBLISH / "Go Live" — Dev Plan
+
+TODO ref: **#16c** in `todo/TODO_2026-06-20_pre-launch.md` (this doc expands the
+stub). Companion to **`docs/live-ingest-plan.md`** (#16, watch-only) — the *watch*
+side (Live tab, player, chat, zaps) is built there and **reused** here; this doc
+adds the *broadcast* side.
+Status: **FUTURE / exploratory — all six decisions LOCKED** (see Core Decision's
+blanket rule: bitvid hosts nothing; self-host or external only). Sequenced
+**after** #16 (live ingest) and #16b (shorts). The largest plan, and the only one
+touching **(self-hosted, never bitvid-run) media infrastructure**.
+
+---
+
+## Core decision
+
+> **BLANKET RULE (maintainer, non-negotiable): bitvid.network hosts NOTHING but a
+> static client — no servers, no media infrastructure, ever.** All media
+> receiving/routing is **self-hosted by the creator** (the Bridge run headless — a
+> single self-hosted binary, see `docs/bitvid-bridge-plan.md`) or handled by an
+> **external provider** (zap.stream/YouTube/Twitch). There is no bitvid-operated
+> Media Node and no managed publishing — those options are off the table.
+
+Build **BitVid Live** as a **Nostr-native live-stream control layer**, not a
+video-hosting backend. BitVid the client stays exactly what it is — a static site
+that signs client-side, holds no keys, runs no server. The one thing a static
+browser app genuinely *cannot* do (receive + route live media) is isolated into a
+**separate, self-hosted-or-external** service (never bitvid-operated). Split:
+
+```
+BitVid static client   = identity, metadata, NIP-53 publishing, discovery, chat,
+                         zaps, player UI, archive→VOD publishing
+Media Node / Bridge    = RTMP/SRT/WHIP ingest, HLS/WebRTC output, recording,
+   (self-hosted OR       restreaming, status API
+    external provider)
+```
+
+This keeps BitVid's architecture intact while adding broadcast. Crucially,
+**most of these modes need no bitvid infrastructure at all** — see the three-tier
+spectrum next.
+
+---
+
+## Provider options — three tiers (bitvid hosts none of them)
+
+The creator chooses who receives their media; bitvid only ever **publishes the
+resulting `streaming` URL and plays it**. A VPS is only the *most sovereign* tier,
+not a requirement — most creators never run a server.
+
+| Tier | Setup / cost | Playback in bitvid | Trade-off | bitvid work |
+|------|--------------|--------------------|-----------|-------------|
+| **1. Platform embed** — StreamYard/OBS → YouTube/Twitch | free, **zero infra** | their **iframe** embed | their rules/ads; no native playback, no P2P/WebTorrent | external-embed adapter |
+| **2. Serverless RTMP→HLS API** — Livepeer / Mux / Cloudflare Stream | ~free–cheap, **no server** | **native HLS** (+ P2P-assist possible) | small cost at scale; a 3rd-party account | native HLS (from #16) |
+| **3. Self-hosted node** — the Bridge run headless on a VPS | most effort/cost | native HLS | full **sovereignty + WebTorrent VOD + restream** | native HLS + Bridge |
+
+- **Recommended default "no-VPS but native": Tier 2, Livepeer** — decentralized,
+  crypto-native, cheapest-aligned; the creator points OBS/StreamYard at Livepeer's
+  RTMP ingest and pastes the HLS URL into bitvid. [Mux](https://www.mux.com/live)
+  (free delivery allotment; live needs a paid quality tier) and
+  [Cloudflare Stream](https://developers.cloudflare.com/stream/pricing/) (free
+  ingest/encoding, cheap delivery) are alternatives.
+- **StreamYard is a studio, not a CDN** — it broadcasts *out* to
+  YouTube/Twitch/custom-RTMP (custom RTMP is paid), so with bitvid it's a Tier-1
+  encoder feeding YouTube/Twitch, or a Tier-2/3 encoder feeding a serverless
+  API / your node.
+- **The same NIP-53 event + player serve all three tiers** — the only per-tier
+  code is the playback adapter (external embed vs native HLS). So supporting the
+  spectrum is cheap, and the VPS/Bridge is the *advanced* tier, not the default.
+
+---
+
+## Relationship to the other two plans
+
+- **#16 (live-ingest) is a hard dependency.** It builds the NIP-53 **parsers**
+  (30311/1311), the **Live tab**, `LiveCard`, `LivePlayer`, `LiveChatPanel`, HLS
+  playback (hls.js), and host zaps. This plan **reuses** all of that to *watch*
+  streams and adds the **builders** + Studio + Media Node/Bridge to *create* them.
+- **Shared Phase 0 schema.** #16 adds `parseLiveStreamEvent`/`parseLiveChatMessageEvent`;
+  this plan adds `buildLiveStreamEvent`/`buildLiveChatMessageEvent`/
+  `updateLiveStreamStatusEvent`. Do them in `js/nostrEventSchemas.js` together so
+  the catalogue stays consistent — coordinate so they aren't duplicated.
+- **My Videos "Live" sub-tab** (noted in the shorts plan) belongs to *this*
+  feature — managing your own streams only makes sense once you can publish.
+
+---
+
+## Why BitVid Live — advantages over the incumbents
+
+Lean into what only bitvid can offer; these are the reasons a creator would pick
+BitVid Live over zap.stream/Twitch/YouTube.
+
+- **P2P bandwidth offload (WebTorrent-flavored live).** Classic WebTorrent can't
+  carry a live stream (its infohash needs the *complete* file), but **P2P-assisted
+  HLS** can: hls.js + [P2P Media Loader](https://github.com/novage/p2p-media-loader)
+  (historically WebTorrent-tracker-based) lets concurrent viewers share HLS
+  segments over WebRTC, so each extra viewer helps *serve* the stream. This
+  directly cuts the Media Node's egress — the biggest cost of running live infra —
+  and scales *better* the more popular a stream gets. (Enable when concurrency
+  warrants; see the ingest plan.)
+- **Recordings become full WebTorrent VODs.** The moment a stream ends, its
+  recording is an ordinary bitvid video: complete file → infohash → **seed +
+  webseed**, playable P2P + URL like everything else. Twitch/YouTube VODs are
+  origin-only; bitvid VODs are P2P-distributable and self-hostable.
+- **Nostr-native = portable + no lock-in.** The stream is a signed NIP-53 event on
+  relays, not a row in a platform DB. It's discoverable by *any* Nostr app, the
+  creator owns it, and it can't be de-platformed by a single company.
+- **Zaps built in.** Instant Lightning value-for-value to the host during the
+  stream (bitvid's existing NWC/zap system) — no ads, no 50% platform cut, no
+  payout thresholds.
+- **Bring-your-own everything.** Own storage (R2/B2/S3/MinIO) for recordings, own
+  relays, self-hostable Media Node, and an **external-provider-only mode that needs
+  zero bitvid infra**. No mandatory middleman.
+- **One canonical stream, many mirrors.** Restream to YouTube/Twitch/zap.stream
+  simultaneously while bitvid stays the sovereign home — reach without lock-in.
+- **Archive is a first-class video, not a throwaway.** VODs flow into the same
+  feeds, search, moderation, comments, and zaps as every other bitvid video (the
+  `s`-tag/info.json/30078 model) — no separate "past broadcasts" ghetto.
+- **Self-sovereign identity.** The creator signs; no BitVid account, no bridge
+  ever holds their key.
+
+---
+
+## Decisions needed
+
+> **DECISION 1 — Media hosting model. ✅ LOCKED by the blanket rule: a three-tier
+> provider spectrum — bitvid hosts NONE of them.** The creator picks who receives
+> their media; bitvid just publishes the resulting `streaming` URL. **A VPS is only
+> the *most sovereign* tier, not a requirement.** See "Provider options" below:
+> 1. **Platform embed** (StreamYard/OBS → YouTube/Twitch) — free, zero infra;
+>    bitvid embeds their player. **Ships first (Phase 1).**
+> 2. **Serverless RTMP→HLS API** (Livepeer / Mux / Cloudflare Stream) — no server
+>    to run; the creator gets a real HLS URL bitvid plays **natively**. The
+>    recommended "no-VPS but native" default. **Livepeer** is the most aligned.
+> 3. **Self-hosted node** (the Bridge run headless on a VPS) — full sovereignty +
+>    WebTorrent VOD + restream control; most effort. The advanced tier.
+>
+> The managed-BitVid-node option is **removed**. bitvid's job (publish the event,
+> play the `streaming` URL) is **identical across all three** — the only code
+> difference is a per-tier playback adapter (external embed vs native HLS).
+
+> **DECISION 2 — Signing during a live stream. ✅ LOCKED: A for MVP, B (NIP-46)
+> later; D removed by the blanket rule.** The node must NOT hold the creator's key.
+> **(A) BitVid tab/app stays open** and signs status=live/ended (matches the
+> Bridge's embedded-webview design) — MVP. **(B) NIP-46 remote signer** for a
+> hands-off experience — later. **(C)** a *self-hosted* node may also publish
+> provider-status under its own pubkey while the canonical 30311 stays user-signed
+> — available to self-hosters. **(D) managed publishing account is off the table**
+> (blanket rule).
+
+> **DECISION 3 — Transcode. ✅ LOCKED: pass-through only (`-c copy`) in v1.**
+> Require H.264/AAC + ~2s keyframes in; no transcode ladders. Transcoding is a
+> heavy, self-hoster-only opt-in much later, if ever.
+
+> **DECISION 4 — WebRTC low-latency. ✅ LOCKED: HLS first, WebRTC later.** HLS
+> (~6–30s) works everywhere via #16's hls.js; WebRTC (<500ms) is a later phase.
+
+> **DECISION 5 — Local Bridge in MVP. ✅ LOCKED: not required for the external-
+> provider MVP; it IS the self-hosting path (DECISION 1b).** With the blanket rule,
+> self-hosting a Media Node **is** running the Bridge headless, so the Bridge isn't
+> an optional extra for self-hosters — it's *the* mechanism. The external-provider
+> MVP (Phase 1) still needs neither. Full plan: `docs/bitvid-bridge-plan.md`.
+
+> **DECISION 6 — Flag naming. ✅ LOCKED: keep the specific split.**
+> `FEATURE_LIVE_INGEST` / `_PUBLISH` / `_BRIDGE` / `_RESTREAM` (+ `_CHAT_POST` from
+> #16). No umbrella `FEATURE_LIVE`. `FEATURE_LIVE_PUBLISH` implies ingest is on.
+
+---
+
+## Config flags (off = no trace)
+
+Every "Go Live" surface is instance-config gated and defaults **off**, threaded
+`config/instance-config.js` → `js/config.js` → `js/constants.js` like
+`FEATURE_NIP71_INGEST`. An operator can ship the code and have publishing be
+completely invisible until they opt in.
+
+- `FEATURE_LIVE_INGEST` — watch side (from #16; a dependency of publish).
+- `FEATURE_LIVE_PUBLISH` — the Studio / Go-Live publishing UI (the master
+  publish switch).
+- `FEATURE_LIVE_BRIDGE` — Media Node / Bridge session API integration.
+- `FEATURE_LIVE_RESTREAM` — external restream output management.
+
+**Independent of watching.** These are separate from `FEATURE_LIVE_INGEST`, so an
+instance can enable *watching* live streams without enabling *broadcasting* (or
+vice-versa). `FEATURE_LIVE_PUBLISH` implies ingest is on (you watch your own
+stream); it does not force ingest on for everyone if the operator wants
+watch-only.
+
+When `FEATURE_LIVE_PUBLISH` is off, **all** of the following are absent — no tab,
+no button, no trace (as if never added):
+1. **"Go Live" / Studio entry points** — no Studio launch anywhere (sidebar,
+   upload modal, profile).
+2. **My Videos → Live sub-tab** — not rendered (shorts-plan sub-tab treatment).
+3. **Live-event builders** — `buildLiveStreamEvent` / `updateLiveStreamStatusEvent`
+   are not wired into any UI (the schema definitions can exist dormant; nothing
+   *invokes* them).
+4. **Bridge/session UI** — pairing, ingest settings, health dashboard (also gated
+   on `FEATURE_LIVE_BRIDGE`).
+5. **Restream UI** — output manager (also gated on `FEATURE_LIVE_RESTREAM`).
+6. **Archive→VOD "publish recording"** live-origin flow (a normal video upload is
+   unaffected).
+7. **Routes** — any `#view=live-studio` (or equivalent) falls back to default.
+8. **Config surface** — the flags are the only footprint.
+
+Bridge and restream have their own sub-flags so an operator can allow, e.g.,
+publishing to their own Media Node **without** exposing external restreams.
+
+**Who may go live (operator control).** Beyond the on/off flags, publishing on an
+instance should respect the existing **whitelist/WoT** model — i.e. an operator
+can allow only whitelisted creators to broadcast on their instance (reusing
+`accessControl`), the same way the feeds are gated. Decide whether go-live is
+whitelist-gated by default (recommended: yes on whitelist-mode instances) so a
+public instance isn't an open ingest relay.
+
+---
+
+## Event model (NIP-53 — shared with #16)
+
+Canonical live address = `30311:<creator-pubkey>:<d-tag>` (an addressable
+replaceable event; dedupe by pubkey + `d`, exactly like bitvid treats video
+`d`-tags). Key tags: `d`, `title`, `summary`, `image`, `streaming` (HLS/WebRTC
+playback URL — the canonical first entry), `recording` (VOD when ended), `starts`,
+`ends`, `status` (`planned`/`live`/`ended`), `relays`, `t` (hashtags), `p` (host +
+participants), `service`.
+
+Live chat = **kind 1311**, anchored to the activity via
+`['a', '30311:<pubkey>:<d>', '<relay>', 'root']` — so bitvid live chat is just
+Nostr, reusing #16's chat pipeline.
+
+Schema work (in `js/nostrEventSchemas.js`, coordinated with #16):
+- `NOTE_TYPES.LIVE_STREAM` (30311), `NOTE_TYPES.LIVE_CHAT_MESSAGE` (1311).
+- Builders: `buildLiveStreamEvent`, `updateLiveStreamStatusEvent`,
+  `buildLiveChatMessageEvent`. Parsers: from #16.
+- Helper: `getLiveAddress(pubkey, d)` → the canonical `a` coordinate.
+
+**Safety invariant:** the public 30311 event carries **only** the playback URL and
+public metadata. **Never** publish RTMP/SRT ingest URLs or stream keys into Nostr.
+
+---
+
+## Auth & key custody (the non-negotiables)
+
+1. **BitVid signs; the Bridge routes.** The Media Node/Bridge never receives the
+   creator's Nostr private key. It controls *media sessions*, not *identity*.
+2. **Bridge auth via NIP-98 HTTP-Auth (kind 27235).** bitvid already has this
+   builder (`buildHttpAuthEvent`, `js/nostrEventSchemas.js`). The client signs a
+   27235 event ("I, pubkey X, authorize creating session Y at URL Z"); the node
+   verifies the signature, mints a stream key, returns ingest/playback URLs.
+3. **Stream keys stay out of Nostr** — held node-side (encrypted config / secret
+   store) or, in local-Bridge mode, in the OS keychain. Public event gets the HLS
+   URL only.
+
+---
+
+## Architecture — four pieces
+
+- **BitVid Live Client** *(static app; reuses #16)* — browse/watch, render NIP-53,
+  play HLS/WebRTC/external, chat + zaps, planned/live/ended state, and the
+  **archive→VOD** convert flow.
+- **BitVid Live Studio** *(static app; new, this plan)* — create live-event
+  metadata, publish planned→live→ended NIP-53 updates, show OBS/encoder ingest
+  settings, connect to Bridge/Node, monitor health, manage restream outputs,
+  publish the recording.
+- **Media Node** *(server-side; **self-hosted by the creator**, never bitvid-run)*
+  — RTMP/SRT/WHIP ingest → HLS/WebRTC out, recording, S3-compatible upload, status
+  API, optional restream. **Built on
+  [MediaMTX](https://mediamtx.org/docs/kickoff/introduction)** — not from scratch.
+  Per DECISION 7 it's the **same binary as the Bridge, run headless**.
+- **BitVid Bridge** *(the self-hosting vehicle — desktop app or headless node)* —
+  local RTMP/SRT receiver for hardware encoders, one-input→many-outputs restream,
+  local recording, archive upload, OBS-WebSocket control. **This is how a creator
+  self-hosts** (DECISION 1b) and the seed of a future "BitVid Box".
+
+New client modules (matching repo style): `js/services/liveEventService.js`,
+`liveChatService.js`, `liveBridgeClient.js`, `livePlaybackService.js` (or extend
+#16's), `liveArchiveService.js`; UI `js/ui/views/LiveStudioView.js`,
+`js/ui/components/{LiveBridgeSetup,LiveRestreamOutputs}.js` (LiveCard/LivePlayer/
+LiveChatPanel come from #16).
+
+---
+
+## Media Node & Bridge API
+
+One stable path per session: `/live/<creator-pubkey>/<d-tag>`. Ingest via RTMP /
+SRT / WHIP (key/token kept secret); playback via HLS (`/index.m3u8`) / WebRTC. The
+client publishes only the playback URL into the 30311 `streaming` tag.
+
+Bridge API surface (session lifecycle + SSE/WebSocket status):
+`POST /sessions`, `GET /sessions/:id`, `.../start`, `.../end`, `.../outputs*`,
+`GET /sessions/:id/status|manifest`, `GET /events` (SSE stream of
+`input_connected|input_live|input_lost|recording_finalized|upload_complete|…`).
+The client listens and decides when to sign+publish NIP-53 updates (DECISION 2).
+
+---
+
+## Outgoing streams — three distinct concepts
+
+- **A. Primary BitVid output** — OBS/encoder → Media Node → HLS/WebRTC → the URL
+  that goes in the 30311 `streaming` tag.
+- **B. External restream outputs** *(`FEATURE_LIVE_RESTREAM`)* — the node forwards
+  the same encoded stream to YouTube/Twitch/zap.stream/custom RTMP/SRT.
+  **Stream-copy only** in v1 (`-c copy`, no transcode — MediaMTX `runOnReady` +
+  FFmpeg forward). Output keys stay node-private; public mirrors optionally added
+  as `['r', <public-watch-url>]`.
+- **C. Archive / VOD output** — on end, MediaMTX records fMP4/TS → finalize →
+  upload to R2/B2/S3/MinIO → produce `recording.mp4` + `.info.json` (+ optional
+  thumbnail/torrent). This maps **directly onto bitvid's existing storage-pointer
+  model**: the `['s', '<provider>:<prefix>']` tag + `js/utils/storagePointer.js`
+  already derives `<prefix>.info.json`, so the archived stream becomes an ordinary
+  bitvid video with zero new playback/metadata code.
+
+---
+
+## Archive → VOD publishing (reuses everything)
+
+When the Bridge returns a recording manifest (url, thumbnail, duration, sha256,
+infoJson, optional torrent/magnet/webseed), the Studio shows **"Publish recording
+as a BitVid video."** On click bitvid publishes:
+1. **Updated 30311** — `status=ended` + `recording=<url>`.
+2. **Canonical bitvid video** — **kind 30078** (Content Schema v3, the same event
+   the upload modal produces) with the hosted URL + `s` pointer.
+3. **Optional NIP-71 mirror** — bitvid's addressable **34235** (normal) via the
+   existing mirror service, so other apps see the VOD (per the nip71 plan; note
+   bitvid mirrors to 34235/34236, not raw kind 21).
+
+This is a specialized upload-modal flow, not a new publishing system.
+
+---
+
+## Playback strategy
+
+Live: **HLS first** (works everywhere via #16's hls.js), then WebRTC later
+(DECISION 4), then external-embed fallback. Mirror bitvid's URL-first ethos:
+**primary live URL → external mirror → ended recording (VOD).** Optional
+**P2P-assisted HLS** (P2P Media Loader) offloads Media Node egress once a stream
+has enough concurrent viewers — see the ingest plan + Advantages above. The ended
+**recording gets full classic WebTorrent** (seed + webseed), like any bitvid video.
+
+---
+
+## Build order & the static-first principle
+
+> **PRIORITY (maintainer): pour effort into the static bitvid client before
+> branching into any separate app.** Everything through the Go-Live MVP below lives
+> **entirely in the static client** — no Bridge, no VPS, no bitvid infra. The
+> Bridge (a second application) is deliberately deferred until this is shipped and
+> maximally developed. See `docs/bitvid-bridge-plan.md`.
+
+Recommended sequence across the live/short work:
+
+```
+1. Shorts (#16b)             ← smallest, ready to build, unrelated to live
+2. Live ingest (#16)         ← the WATCH foundation (Live tab, player, hls.js,
+                               chat, zaps) — a hard dependency of publishing
+3. Go-Live MVP (#16c P0–P1)  ← Tiers 1 & 2 (external embed + serverless HLS);
+                               CLIENT-SIDE ONLY, no Bridge / no VPS / no infra
+   ── ship it; validate that people actually want live ──
+4. (only if warranted) the Bridge app  ← Tier-3 sovereignty/power features;
+                               its own repo/toolchain/code-signing — a later track
+```
+
+The Go-Live MVP (steps 1–3) is the "as much static bitvid as possible" target: a
+real, working live experience where the creator brings their own provider
+(StreamYard→YouTube, or OBS→Livepeer/Mux) and bitvid does the Nostr-native part —
+publish, discover, watch, chat, zap, archive→VOD. Only after that proves out does
+a second app (the Bridge) earn the investment.
+
+---
+
+## Phases
+
+- **Phase 0 — Flags + schema (small).** `FEATURE_LIVE_PUBLISH/BRIDGE/RESTREAM`;
+  30311/1311 **builders** + `updateLiveStreamStatusEvent` + `getLiveAddress`
+  (coordinate with #16's parsers); `docs/live.md`; schema-doc update; unit tests.
+- **Phase 1 — Provider-agnostic publishing (small; NO infra — Tiers 1 & 2).**
+  "Create Live Stream" modal: title/summary/thumbnail/tags/starts + a paste-in
+  `streaming` URL / platform link; publish planned→live→ended; chat + zaps against
+  the live address (reusing #16). Playback adapter picks **external embed**
+  (Tier 1: YouTube/Twitch) or **native HLS** (Tier 2: Livepeer/Mux/Cloudflare).
+  *This is BitVid Live v0, needs zero servers, and covers the recommended no-VPS
+  path (Tier 2 / Livepeer).*
+- **Phase 2 — Bridge API client + mock backend (medium).** `liveBridgeClient`,
+  Pair-Bridge UI, mocked `/sessions`, setup wizard, status dashboard,
+  recording-ready flow — builds the client contract before real infra exists.
+- **Phase 3 — Self-hosted Media Node MVP (large, server-side).** A **reference
+  node the creator runs themselves** (never bitvid-operated) around MediaMTX:
+  session API, NIP-98-verified auth, token'd RTMP ingest, HLS playback, start/stop
+  detection, status endpoint. OBS → the creator's node → bitvid watches. No keys in
+  Nostr. Per DECISION 7 (Bridge plan) this is the **same binary as the Bridge, run
+  headless** — so Phase 3 and Phase 7 share code. *This is BitVid Live v1.*
+- **Phase 4 — Recording → archive → VOD (medium).** MediaMTX recording → finalize
+  → S3 upload → manifest → the archive→VOD publish flow above.
+- **Phase 5 — Restream outputs (medium; `FEATURE_LIVE_RESTREAM`).** Output manager,
+  provider presets (YouTube/Twitch/zap.stream/custom), copy-only forward,
+  retry/backoff, per-output status. One canonical `streaming` URL; mirrors are
+  optional `r` links.
+- **Phase 6 — OBS Companion (medium).** Start/stop OBS + read bitrate/dropped
+  frames via OBS-WebSocket (built into OBS 28+). Prefer routing through the local
+  Bridge to avoid browser↔localhost/mixed-content pain.
+- **Phase 7 — Local Bridge app (large; `FEATURE_LIVE_BRIDGE`).** Packaged desktop
+  helper: local RTMP/SRT receiver, forward to Node + external, local record +
+  archive upload, embedded Studio webview (signs) + optional localhost API.
+  *BitVid Live v2 / "BitVid Box" seed.* **Full plan: `docs/bitvid-bridge-plan.md`**
+  (cross-platform app; note DECISION 7 there — the Bridge and this Media Node can
+  share one codebase running headless vs with-UI).
+- **Phase 8 — WebRTC low-latency (later, DECISION 4).**
+
+---
+
+## Engineering rules (invariants)
+
+1. **BitVid signs; the Bridge routes** — the node never owns the creator's Nostr
+   identity.
+2. **Public playback URLs are safe; ingest URLs are secret** — publish the
+   `.m3u8`, never `rtmp://…?key=SECRET`.
+3. **Pass-through first, transcode later** — copy the H.264/AAC stream in v1.
+4. **One canonical stream, many optional mirrors** — the 30311 has one `streaming`
+   URL; external platforms are outputs, not the source of truth (unless the creator
+   picks an external provider as primary in Phase-1 mode).
+5. **Archived live streams become normal BitVid videos** — no separate archive
+   system; reuse the `s`-tag / info.json / 30078 model.
+
+---
+
+## Risks / watch-items
+
+- **bitvid stays static; infra is the creator's.** The Media Node/Bridge is real
+  server infra, but per the **blanket rule it's never bitvid-operated** — it's
+  self-hosted by the creator or replaced by an external provider. So the ops/cost
+  burden lives with whoever self-hosts, not bitvid.network. The static client is
+  unaffected; Phase-1 external mode needs no infra at all.
+- **Self-hoster burden (DECISION 1b).** Bandwidth/storage cost, encoder config, and
+  keeping the node reachable fall on the self-hoster. Good docs + a turnkey
+  headless Bridge (one binary) are the mitigation.
+- **Signing during long streams (DECISION 2).** Tab-open (A) is fragile for long
+  broadcasts; NIP-53 lets clients treat a live event with no update in ~1h as
+  ended, so plan a heartbeat and a graceful "stale → ended" story.
+- **CORS / cross-origin HLS** — segments served by the (self-hosted) node's origin
+  must allow the bitvid origin (same class as the storage/edge CORS work).
+- **Encoder compatibility** — pass-through requires H.264/AAC + sane keyframes;
+  document encoder settings; reject or warn on incompatible input.
+- **Scope discipline** — publishing is genuinely large; ship Phase 1 (no infra)
+  first and treat the Media Node as a separate service milestone.

+# Shorts (short-form vertical video) — Dev Plan
+
+TODO ref: **#16b** in `todo/TODO_2026-06-20_pre-launch.md`.
+Status: **DECISIONS LOCKED — ready to build** (D1–D5, D7, D8 locked; D6 is a
+build-time implementation choice). Not started.
+
+Short-form vertical video is **NIP-71 kind 22** (the short counterpart to kind 21
+normal video), plus the addressable short kind **34236**. It is a *different*
+feature from live streams (#16, NIP-53) — do not conflate them.
+
+The good news: **bitvid already ingests kind 22.** The inbound NIP-71 adapter
+(`js/nostr/nip71IngestAdapter.js`, `NIP71_KINDS = {21, 22, 34235, 34236}`) parses
+short-form notes today and they already flow into the main feed. So this feature
+is **not new ingest code** — it is (a) a single `isShort` discriminator (native
+marker / foreign kind), (b) a dedicated **Shorts sidebar tab** with a vertical
+UI, (c) a feed source that lists only shorts, (d) **exclusion of shorts from the
+main/discovery feeds** (DECISION 3), and (e) a **publish-side content-type
+selector** + native short marker (DECISION 7) so bitvid creators can post shorts.
+Everything ships behind a config flag that leaves **no trace** when off.
+
+---
+
+## Decisions needed
+
+> **DECISION 1 — Discovery scope. ✅ LOCKED: Option A (same whitelist scope).**
+> Shorts pulls from the same whitelisted/WoT authors as the main feed and reuses
+> the existing render-time moderation filter — no new moderation surface, no extra
+> relay fan-out. Rationale (maintainer): the existing moderation + ingest system
+> is already good; keep Shorts consistent with it. A broader/Explore-style scope
+> can be added later if desired.
+
+> **DECISION 2 — Moderation / NSFW. ✅ LOCKED: Option A (inherit, no special
+> handling).** Shorts pass through the same render-time `filterVideos` path as
+> every grid (event blacklist / author blacklist / WoT mute / NSFW / private).
+> No short-specific moderation. Note: the NSFW gate already *excludes* NSFW from
+> users who haven't opted in, so the immersive autoplay feed carries no extra
+> NSFW-exposure risk — opted-in users chose to see it, everyone else never
+> receives it. Rationale (maintainer): no reason to treat shorts differently.
+> **One agreed safeguard:** even for opted-in users, an **NSFW short does NOT
+> autoplay** in the immersive feed — it stays blurred/paused with a tap-to-play
+> affordance (autoplay resumes on the next non-NSFW short). This is the only
+> short-specific behavior; all *filtering* still inherits the shared pipeline.
+
+> **DECISION 3 — Do shorts also appear in the main feed? ✅ LOCKED: Option B
+> (Shorts tab ONLY; excluded from the main/discovery feeds).** Rationale
+> (maintainer): shorts should not dilute the main feed at all — the Shorts tab is
+> their only home.
+> **Build implication:** add an `isShort` **exclusion** to the general feeds —
+> Recent, For You, Explore, Trending, Kids — so kind-22/short videos never render
+> there (they currently do via NIP-71 ingest). The Shorts feed is the inverse
+> filter (`isShort` only). This touches each feed source/sorter, so verify no
+> feed regressions (couples with #20/#21 feed-identity work).
+> **Sub-point (recommend, not blocking):** a creator's shorts SHOULD still appear
+> on their **Channel profile** page (it's their full catalogue) and in
+> **Subscriptions** is TBD — default: exclude from Subscriptions too (it's a
+> discovery feed), keep on Channel profile. Confirm during Phase 1.
+
+> **DECISION 4 — What counts as a "short"? ✅ LOCKED: Option A (kind is the
+> definer).** A video is a short iff its event kind is **22** or **34236**;
+> kind 21/34235 = regular. No aspect-ratio heuristic — the publisher's declared
+> kind decides. Rationale (maintainer): shorts are typically vertical, but the
+> protocol kind is the source of truth; a vertical video mis-published as regular
+> just renders in the 16:9 card (thumbnail center-cropped via `object-fit:cover`;
+> the player letterboxes it via `object-fit:contain`, never distorts) and stays in
+> the main feed — the publisher's choice. Aspect-ratio fallback can be added later
+> if too many real shorts leak in as kind-21.
+
+> **DECISION 5 — UI ambition for v1. ✅ LOCKED: Option C (phased).** Phase 1 ships
+> the grid + portrait card + the main-feed exclusion (DECISION 3) so shorts are
+> corralled into their own tab immediately (the maintainer's priority); Phase 2
+> adds the full immersive autoplay/swipe feed later. Front-loads "shorts out of
+> the main feed," defers the heavier immersive build.
+
+> **DECISION 6 — Card design.** Shorts need a **new portrait (9:16) card** — the
+> existing `js/ui/components/VideoCard.js` hardcodes a **16:9 landscape** media
+> ratio (`ratio-16-9`), so it can't render shorts correctly as-is. Two options:
+> (a) a **new `ShortCard` component** (portrait thumbnail, compact meta, its own
+> `data-testid`); or (b) a **portrait "mode"/variant of `VideoCard`** driven by a
+> flag (e.g. `variant: "short"` swapping the ratio class + layout).
+> *Recommendation: (b) a portrait variant of `VideoCard` if the internals are
+> clean enough to parameterize the ratio + layout — it inherits thumbnail
+> binding, moderation badges, engagement controls, and the ⋯ menu for free;
+> fall back to (a) a dedicated `ShortCard` only if forcing a variant makes
+> `VideoCard` unwieldy or pushes it past its size cap.* Either way this is a
+> **first-class deliverable**, not an afterthought — the grid can't ship without it.
+
+> **DECISION 7 — Publish side: content-type selector + native short marker.
+> ✅ AGREED (maintainer-proposed).** Add an **upload-modal content-type selector**
+> (Regular video ⟷ Short) with **visual + text helpers** so creators pick the
+> right type and understand placement — e.g. landscape/portrait icons + copy like
+> *"Shorts appear only in the Shorts tab, not the main feed."* This is not just
+> UX: bitvid's canonical event is **kind 30078** (not 21/22), and the schema has
+> **no short marker today** (short is only inferred from dimensions at mirror
+> time). So this decision also adds an explicit **`isShort` (or `format:
+> "short"`) field to the v3 content schema**, set by the selector, which (a) lets
+> the Shorts feed filter + main-feed exclusion catch bitvid-native shorts, and
+> (b) forces the NIP-71 mirror to kind **34236**. Detection becomes: a video is a
+> short iff `kind ∈ {22,34236}` (foreign/ingested) **OR** `isShort === true`
+> (bitvid-native). *Open sub-choices for build time: default selection (recommend
+> "Regular"), whether to auto-suggest "Short" when the uploaded file is portrait,
+> and exact copy/icons.*
+
+> **DECISION 8 — Native short representation. ⏳ LEANING: marker on kind 30078
+> (both options mirror to 34236).** Hard requirement (maintainer): a native short
+> MUST keep bitvid's WebTorrent advantage AND mirror to the standard NIP-71 short
+> kind via the existing mirror system. Both viable options satisfy that — they
+> produce the *same external result* (a WebTorrent-rich native event + a standard
+> **34236** mirror carrying the magnet via `imeta`):
+>
+> - **Option 1 (recommended) — kind 30078 + `isShort` marker.** Native short = a
+>   normal bitvid video flagged short; the *existing* mirror emits 34236. No new
+>   kind. Reuses 100% of the publish/edit/delete/moderation/view-count/zap/mirror
+>   pipeline (all keyed on 30078). Least code, least risk.
+> - **Option 2 — a distinct bitvid-short kind that mirrors to 34236.** A separate
+>   kind number for rich native shorts + the mirror to 34236 for interop.
+>   *Trade-off:* the external result is identical to Option 1, but the distinct
+>   *native* kind is non-standard (only the 34236 mirror is recognized by other
+>   clients) and it forks every pipeline that's currently keyed on 30078 — i.e.
+>   more work for the same outcome. A new kind buys a distinct native kind number;
+>   it does **not** buy WebTorrent or interop that Option 1 lacks.
+>
+> Net: Option 1 already delivers "WebTorrent + mirror to the standard kind"
+> without minting a kind. Only pick Option 2 if a distinct native kind number is
+> itself a requirement.
+>
+> **✅ LOCKED: Option 1 (marker on kind 30078), provided shorts are reliably
+> distinguishable.** They are: a single `isShort` boolean discriminates them
+> everywhere — set from the `isShort`/`format:"short"` content field for native
+> videos and from `kind ∈ {22,34236}` for ingested ones (see Field mapping). The
+> Shorts feed filters `isShort === true`; the main feeds exclude it.
+
+---
+
+## Config flag (off = no trace)
+
+Add `FEATURE_SHORTS` to `config/instance-config.js` (default `false`), threaded
+through `js/config.js` → `js/constants.js` exactly like `FEATURE_NIP71_INGEST`.
+
+When the flag is off, **all** of the following must be absent (the "as if it were
+never added" requirement):
+1. **Sidebar tab** — the Shorts link is not rendered in `components/sidebar.html`
+   (not merely `hidden`).
+2. **Feed registration** — `FEED_TYPES.SHORTS` is not registered in
+   `js/app/feedCoordinator.js` (no pipeline, no sorter).
+3. **Subscription/source** — no shorts-specific relay subscription is created.
+4. **Route** — `#view=shorts` falls back to the default view (a stale bookmark
+   can't resurrect the tab).
+5. **Publish UI** — the upload-modal content-type selector (DECISION 7) is not
+   rendered; uploads are plain regular videos exactly as today.
+6. **Management UI** — no Shorts sub-tab in profile → My Videos (see below).
+7. **Config surface** — the flag is the only footprint.
+
+---
+
+## Publish & management UI (flag-gated)
+
+Both the publish and management surfaces must obey "off = no trace" (points 5–6
+above), and reuse patterns already in the app.
+
+- **Upload modal — content-type selector (DECISION 7).** Regular ⟷ Short, with
+  visual + text placement helpers ("Shorts appear only in the Shorts tab").
+  Rendered only when `FEATURE_SHORTS` is on; otherwise uploads are plain regular
+  videos exactly as today.
+- **Profile → My Videos — sub-tabs.** Reuse the **admin-pane sub-tab toolbar
+  pattern** just shipped (`ProfileAdminController` sub-tabs) to split My Videos
+  into **Videos / Shorts / Live** sub-tabs for easier content management. Each
+  sub-tab appears **only when its feature flag is on**:
+  - `FEATURE_SHORTS` off → no Shorts sub-tab.
+  - Live sub-tab is tied to **publishing** live (**#16c** / `FEATURE_LIVE_PUBLISH`),
+    NOT ingest (#16) — with ingest-only there is nothing of the user's to manage,
+    so no Live sub-tab.
+  - **All flags off → no sub-tab bar at all**, just the plain My Videos list
+    exactly as today (true "no trace").
+  - Videos sub-tab lists regular bitvid/NIP-71 videos (excludes `isShort`);
+    Shorts sub-tab lists the user's `isShort` videos.
+
+## Field mapping — detecting a "short"
+
+Per DECISION 4 + 7 (locked), `isShort` is derived from **kind for foreign/ingested
+videos** and from an **explicit marker for bitvid-native videos** (kind 30078):
+
+| Signal | Applies to | Meaning |
+|--------|-----------|---------|
+| `kind === 22` | ingested foreign | NIP-71 regular short |
+| `kind === 34236` | ingested foreign | NIP-71 **addressable** short |
+| `isShort` / `format:"short"` in kind-30078 content | **bitvid-native** | set by the upload-modal content-type selector (DECISION 7) |
+| `imeta dim` height > width | (future fallback) | portrait aspect; **not** used in v1 (DECISION 4) — kept only as a possible later fallback |
+
+Plan: surface a single `isShort` boolean on the bitvid video object —
+`nip71IngestAdapter.js` sets it from the source kind (it already tracks kind);
+the native publish path sets it from the new content-schema field. The Shorts
+feed filters `isShort === true`; the main feeds exclude `isShort === true`
+(DECISION 3). No re-fetching needed.
+
+---
+
+## Architecture
+
+Reuses the existing feed engine + ingest; new pieces are thin.
+
+- **Flag:** `FEATURE_SHORTS` (instance-config → config → constants).
+- **Feed type:** add `SHORTS: "shorts"` to `FEED_TYPES` (`js/constants.js`).
+- **Feed source/registration:** register `FEED_TYPES.SHORTS` in
+  `js/app/feedCoordinator.js`, sourced from the already-populated active-video
+  cache filtered to `isShort` (per DECISION 1, scoped to the same authors as the
+  main feed). A dedicated sorter can be chronological or reuse the For-You scorer
+  — TBD, likely chronological for v1.
+- **Sidebar tab:** add a Shorts link in `components/sidebar.html`, rendered only
+  when the flag is on.
+- **View:** `views/shorts.html` (a portrait-oriented grid container).
+- **Card design (new):** a portrait **9:16** card — either a `variant: "short"`
+  mode of `js/ui/components/VideoCard.js` (which is currently 16:9 / `ratio-16-9`)
+  or a dedicated `ShortCard` (DECISION 6). Portrait thumbnail, compact title +
+  author, reuse of thumbnail binding, moderation badges, engagement + ⋯ menu. New
+  design tokens if needed (existing `--video-card-*` tokens live in
+  `css/tokens.css`). A distinct `data-testid` for e2e selectors.
+- **Player UI:** v1 opens a short in the existing player modal with a portrait
+  layout; v2 adds a full-screen vertical swipe/next feed.
+- **Diversity:** apply the existing `spreadAuthors` pass (feed sorters) so the
+  Shorts tab doesn't cluster by creator, consistent with For You / Trending.
+
+---
+
+## Short-form UX best practices (researched July 2026)
+
+Short-form is a **mobile-first** format (~70%+ of social video is watched on
+phones, held vertically), but bitvid is a desktop-capable web app, so the Shorts
+experience must be **responsive** — the same feed, two presentations. Sources at
+the bottom of this doc.
+
+### The immersive feed (both platforms)
+- **One short at a time, full-height 9:16**, not a scroll-list of small cards.
+  The grid (Phase 1) is the *entry point*; tapping/clicking a short drops into an
+  immersive one-at-a-time feed (Phase 2).
+- **Autoplay + loop.** The active short autoplays and loops. Browser autoplay
+  policy requires **muted autoplay** — so start muted with an obvious unmute, and
+  persist the user's mute choice across shorts. **Exception (agreed):** NSFW-
+  flagged shorts do **not** autoplay even for opted-in users — blurred/paused with
+  tap-to-play (see DECISION 2).
+- **Preload the next 2–3.** Buffer upcoming shorts in the background so advancing
+  is instant. "If your platform shows a loading spinner between videos, you've
+  already lost the session." (This is the single most-cited make-or-break detail.)
+- **Overlaid chrome, safe zones.** Title/author bottom-left, an **action rail**
+  bottom-right, controls over the frame — keep them inside 9:16 safe zones so they
+  don't collide with the video edges.
+- **Action rail** (bitvid mapping): **Zap** (bitvid's primary engagement, via the
+  existing NWC/zap system — replaces the generic "like"), **Comment**, **Share**,
+  and **author avatar + follow/subscribe**. Reuse the existing engagement + ⋯
+  menu wiring.
+- **Captions/muted-friendliness.** A large share of viewing happens muted at some
+  point; surface captions when a short provides them and make the mute state
+  obvious. (bitvid can't generate captions — show them when present.)
+- **Accessibility:** respect `prefers-reduced-motion` (no auto-advance / disable
+  scroll-snap animation), full keyboard support, focus management on advance.
+
+### Mobile presentation
+- **Full-screen** vertical player; **swipe up/down = next/previous**; tap =
+  pause/play; the action rail sits on the right thumb-reach edge.
+
+### Desktop presentation
+- **Centered vertical player with letterboxed / blurred side panels** — never
+  stretch a 9:16 short to fill a wide viewport (this is the YouTube-Shorts-on-
+  desktop pattern).
+- **Keyboard navigation is a real differentiator.** YouTube Shorts on desktop has
+  notoriously weak keyboard support (users install extensions to get it). bitvid
+  should ship it natively: **↑/↓ = prev/next short**, **Space = pause/play**,
+  **M = mute**, **←/→ = seek** (or prev/next — pick one and document it), Esc =
+  exit to grid.
+- **Action rail beside the player** (to the right of the letterboxed video) rather
+  than overlaid, since desktop has the horizontal room.
+- Advance via scroll-snap (wheel/trackpad) **and** the arrow keys; a subtle
+  next/prev affordance for mouse users.
+
+### bitvid-specific notes
+- Playback rides the existing URL-first + WebTorrent pipeline (`playbackService`);
+  shorts are ordinary videos (native kind-30078 + `isShort`, or ingested
+  21/22/34235/34236), so **no new transport**.
+- **WebTorrent + autoplay caution:** an autoplaying scroll feed must NOT spin up a
+  torrent swarm per short as the user flies past. In the immersive feed, prefer
+  **URL-first for the active/preloaded shorts** and only fall back to WebTorrent on
+  demand (e.g. when the URL fails, or the short is dwelt on) — otherwise scrolling
+  seeds dozens of swarms and thrashes the connection budget. (Risks section.)
+- Zaps (not likes) are the headline action — a genuine differentiator vs the
+  incumbents that already exists in bitvid.
+- View counts, watch history, comments, and zaps reuse the existing per-video
+  machinery — shorts are just videos to those systems.
+- Everything still flows through the render-time moderation filter (DECISION 2).
+
+## Phases (each flag-gated from day one)
+
+- **Phase 0 — Detection + flag (small).** Add `FEATURE_SHORTS` (off), the
+  `isShort` content-schema field (DECISION 7), and `isShort` derivation (foreign =
+  kind, native = marker) in the ingest adapter + mirror, with unit tests. No UI.
+- **Phase 0b — Publish-side selector (small–medium, DECISION 7).** Upload-modal
+  content-type selector (Regular ⟷ Short) with visual + text placement helpers;
+  wires the `isShort` marker + forces mirror kind 34236. Lets bitvid creators
+  actually publish shorts (without it, the Shorts tab only shows ingested foreign
+  shorts).
+- **Phase 1 — Tab + feed + portrait card + main-feed exclusion (medium).**
+  `FEED_TYPES.SHORTS`, sidebar link, `views/shorts.html`, feed registration
+  filtered to `isShort`, route gated by flag, and the **new portrait 9:16 card**
+  (DECISION 6). **Per DECISION 3 (B):** add the `isShort` **exclusion** to the
+  main/discovery feeds (Recent, For You, Explore, Trending, Kids; likely
+  Subscriptions) so shorts never appear outside the Shorts tab — with regression
+  checks on each feed. Opens in the standard player for now.
+- **Phase 2 — Immersive vertical feed (medium–large).** The one-at-a-time
+  responsive feed described in "Short-form UX best practices": muted autoplay +
+  loop, **preload next 2–3** (no spinner between shorts), overlaid action rail
+  (Zap/Comment/Share/follow), captions-when-present, `prefers-reduced-motion`
+  handling. **Mobile:** full-screen + swipe up/down. **Desktop:** centered
+  letterboxed player + **native keyboard nav** (↑/↓ prev/next, Space, M, Esc) +
+  side action rail. Grid (Phase 1) remains the entry point.
+- **Phase 3 — Polish.** Mute toggle persistence, per-tab empty states, captions
+  surfacing, seek affordance, and the URL-first-for-autoplay WebTorrent guard.
+
+---
+
+## Moderation, whitelist & NSFW
+
+Per DECISION 2 (locked: inherit): shorts pass through the same render-time
+`filterVideos` path (blacklist event ids, author blacklist, WoT mute, NSFW gate,
+private exclusion) as every other grid. No new moderation surface. The admin
+per-event block list (#25) already applies to any event id, shorts included. The
+**one** short-specific behavior is that NSFW-flagged shorts do not autoplay in the
+immersive feed (tap-to-play), even for opted-in users — a playback rule, not a
+filtering change.
+
+---
+
+## Risks / watch-items
+
+- **Main-feed exclusion touches every feed (DECISION 3).** Adding the `isShort`
+  exclusion to Recent / For You / Explore / Trending / Kids (and likely
+  Subscriptions) is the riskiest part — a bug drops the *wrong* videos or lets
+  shorts leak. Regression-test each feed; couples with the #20/#21 feed-identity
+  work. A single shared `isShort` predicate (used positively by Shorts, negatively
+  by the others) keeps it consistent.
+- **A native short missing its marker leaks into the main feed.** Since native
+  detection is the `isShort` content field (not aspect ratio), a bitvid short must
+  reliably carry the marker on publish AND on edit/re-publish, or it reappears in
+  the main feed. Cover publish + edit paths; the marker must round-trip through the
+  mirror/auto-sync.
+- **WebTorrent swarm storm in the autoplay feed.** Preloading + autoplaying a
+  scroll feed over WebTorrent would spin up many swarms at once. Prefer URL-first
+  for active/preloaded shorts; fall back to WebTorrent on demand (see Architecture
+  → bitvid notes). Respect the existing connection budget.
+- **Empty tab** — a whitelist-scoped source (DECISION 1) on a small instance may
+  have few shorts; ship a clear empty state.
+- **Search scope (sub-decision, defer to build).** Should shorts appear in
+  search? They're excluded from the *browse* feeds (DECISION 3) but a user
+  searching a creator/topic arguably still wants their shorts. Recommend: shorts
+  remain searchable and open in the Shorts player context; confirm during Phase 1.

+### 42. Admin whitelist edit fails with nsec / NIP-46 (only NIP-07 worked) — FIXED
+- [x] **DONE 2026-06-30.** Editing the admin whitelist/blacklist worked with a NIP-07
+      extension but silently failed with nsec and NIP-46 (Amber). Root cause:
+      `adminListStore.persistNostrState` signed with `window.nostr.signEvent` directly
+      (and required `requestDefaultExtensionPermissions`), so non-extension logins threw
+      "nostr-extension-missing". Fix: sign with the **active signer**
+      (`getActiveSigner()` from the registry — works for extension/nsec/NIP-46, all expose
+      `signEvent`), and only run the extension-permission prompt when the signer is an
+      extension (`type === "extension"/"nip07"`). Regression test added to
+      `tests/admin-list-store.test.mjs` (nsec signer used while `window.nostr.signEvent`
+      throws). Build + lint clean.
+- [x] **AUDIT DONE 2026-06-30 — clean (adminListStore was the only bug).** Swept every
+      `.signEvent(`, `window.nostr`, and `ensureExtensionPermissions`/
+      `requestDefaultExtensionPermissions` caller:
+      - **Signing:** NO `window.nostr` is used to sign/encrypt anywhere. Every publish
+        path signs with the active signer (`signer.signEvent`): subscriptions, userBlocks,
+        hashtag prefs, relay prefs, moderationService reports, nip71MirrorService,
+        encryptedSyncFacade, DM seal + legacy DM (`nostr/client` signingAdapter defaults
+        to the active signer), DM relay list, admin lists.
+      - **Extension-permission gates:** every caller (reactions, comments, subscriptions,
+        userBlocks, watchHistory, relayManager, DM relays) guards the request behind a
+        signer-type (`extension`/`nip07`) or capability check, so nsec/NIP-46 skip it and
+        go straight to active-signer signing — they never hit the `extension-missing`
+        failure that broke admin lists.
+      - **Decrypt:** gates on the active signer's nip04/nip44 capability with `window.nostr`
+        only as a fallback; nsec (closures) + NIP-46 (remote) both decrypt fine.
+      - **Cleanup note (low priority):** `js/auth/signingAdapter.js`
+        (`createNip07SigningAdapter`, defaults to `window.nostr`) is dead production code —
+        referenced only by its own test, no app callers. Harmless; remove or repoint at
+        the active signer if ever reused.
+
+### 43. Logged-in profile card at the top of the profile modal (UX)
+- [ ] Show the **logged-in user's profile photo + name** at the **top-center** of the
+      profile modal, styled as a "profile card" that sits **half-on / half-off** the
+      modal edge (overlapping the top border) for a polished look. Goal: users can see
+      WHICH profile they're acting as (e.g. uploading as) at a glance. Pull avatar/name
+      from the profile cache for the active pubkey; update on profile switch.
+
+### 44. In-modal storage selector for uploads (UX)
+- [ ] Make storage unlock + selection easier from the **video upload modal**: let the
+      user **pick any configured storage connection** (R2 / B2 / Custom S3) and unlock it
+      **without leaving the upload modal** — today they must close it, open Profile →
+      Storage, change the default/selected connection, then reopen upload. Add a provider
+      picker (driven by `storageService.listConnections`) + inline unlock in the upload
+      modal's storage section; selecting one sets it as the active upload target for this
+      upload (and optionally the default). Reuse `loadFromStorage` / the per-provider
+      connection model.
+
+### 45. Upload modal: suggest tags from the user's previous videos (UX)
+- [x] **DONE 2026-07-01.** The Hashtags section of the upload modal now shows one-tap
+      chips of the user's most-used past hashtags ("Reuse a tag from your videos:").
+      Source: `app.getUserHashtagSuggestions()` reads the user's own videos
+      (`nostrService.getActiveVideosByAuthors([pubkey])`) and ranks their hashtags via
+      `js/utils/hashtagSuggestions.js` `rankHashtagsByFrequency` — count = number of
+      videos using each tag, normalized (case + `#`) and deduped per video, ties broken
+      alphabetically (top 12). Tags come from `video.nip71.hashtags` (falls back to raw
+      `t` tags minus bitvid's fixed `t=video` marker). Clicking a chip adds it to the
+      NIP-71 `t` repeater (skips duplicates); already-added chips dim + disable. Hidden
+      for users with no past tags. Rendered on modal open. Tests:
+      `tests/hashtag-suggestions.test.mjs` (5, pure ranking). Lint + build green.
+
+### 46. Feed auto-refreshes after posting a video (UX)
+- [x] **DONE 2026-06-30.** `publishVideoNote` now (1) **optimistically injects** the
+      just-published legacy event into the shared client cache via a new
+      `nostrClient.ingestLocalVideoEvent(rawEvent)` (+ thin `nostrService` wrapper), so the
+      new video shows in the feed **instantly**, before the relays echo it back; and (2)
+      refreshes via the canonical `refreshAllVideoGrids({ reason: "video-published",
+      forceMainReload: true })` instead of a bare `loadVideos()` — so it refreshes
+      **whichever feed is active** (For You / Explore / Recent) plus the subscription and
+      channel grids, and forces a render (bypassing the load cooldown) so the injected
+      video is actually shown. `ingestLocalVideoEvent` mirrors live ingestion (convert →
+      root created_at → tombstone guard → allEvents/activeMap), so it obeys the same
+      dedupe/active-key rules (#20/#21): a later relay copy of the same event (same
+      `created_at`) won't duplicate it, and an older revision can't overwrite a newer
+      active entry. Tests: `tests/optimistic-feed-insert.test.mjs` (6 — surfaced instantly,
+      no-duplicate on re-ingest, newer-wins, older-doesn't-clobber, invalid→null, garbage
+      handled).
+
+### 47. "Most Zapped" sidebar tab (trending-by-zaps)
+- [ ] Add a **Most Zapped** sidebar tab: like Trending (#27, view-count) but ranked by
+      **total zaps** (sats / zap count) per video. Reuse the zap accounting (kind-9735
+      receipts) already used for the zap system; build a feed source/ranker that sorts by
+      zap total over a window, wired into the feed engine like Trending. Depends on
+      reliable zap data (couples with the zap system already shipped in #3).
+
+### 48. Fluent profile switching across signing methods (nsec / NIP-46 / NIP-07)
+- [x] **nsec switching FIXED 2026-06-30.** Switching to a saved nsec profile used to fail
+      silently ("secret-required") — `switchProfile` called the nsec provider with no
+      passphrase and never prompted. Now `handleProfileSwitchRequest` detects an nsec
+      target, checks the stored key (`getStoredSessionActorMetadata` +
+      `evaluateStoredNsecSwitch` — must be a persisted nsec for THIS account), prompts for
+      the PIN/passphrase via a new `showPasswordPrompt` dialog
+      (`js/ui/promptDialog.js`), and calls `switchProfile(pubkey, { unlockStored: true,
+      passphrase })`. `authService.switchProfile` now forwards `unlockStored`/`passphrase`
+      → `requestLogin` → the nsec provider's `unlockStoredSessionActor` restores the signer
+      and activates the account. Wrong PIN → "Incorrect PIN/passphrase" toast; no stored
+      key / different account → a clear "log in with its nsec" toast. So you can switch
+      NIP-07 → nsec fluently. Tests: `tests/stored-nsec-switch.test.mjs` (6, pure gate) +
+      `tests/password-prompt.test.mjs` (6, dialog). Build + lint clean; auth suites 25/25.
+- [x] **NIP-46 switching FIXED 2026-06-30.** Confirmed the same bug: switching to a saved
+      NIP-46 account called the provider with no `reuseStored`, so it started a fresh
+      handshake (needing a new connect URI/QR) instead of reconnecting. Now
+      `handleProfileSwitchRequest` sends `{ providerId: "nip46", reuseStored: true }` for
+      NIP-46 targets → `switchProfile` forwards `reuseStored` → the nip46 provider's
+      `useStoredRemoteSigner` reconnects the stored session and activates the account. On
+      failure → "Couldn't reconnect to this account's remote signer" toast.
+- [x] **Wrong-account guard (all methods) 2026-06-30.** `requestLogin` now enforces
+      `expectPubkey` (only set by `switchProfile`): if a single-slot stored session
+      resolves to a DIFFERENT account than requested, it rejects with `pubkey-mismatch`
+      instead of silently switching to the wrong profile. Also protects NIP-07 (switching
+      to an account the extension isn't currently on now fails clearly instead of grabbing
+      the extension's active account). Tests in `tests/authService.test.mjs` (option
+      forwarding + expectPubkey rejection).
+- [x] **Multiple nsec accounts — DONE 2026-06-30.** The encrypted-key store is now
+      per-pubkey (`bitvid:sessionActors:v2` = `{ [pubkeyLower]: { privateKeyEncrypted,
+      encryption, createdAt } }`), following the existing `bitvid:<thing>:<npub>`
+      convention (profileCache, nwcSettings, …). Several saved nsec accounts each keep
+      their own key on the device, so the switcher can move between them. The legacy v1
+      single slot is kept in sync as the "last-saved default" (boot restore / no-arg
+      reads) and is migrated into the map on first read. `readStoredSessionActorEntry`,
+      `getStoredSessionActorMetadata`, and `unlockStoredSessionActor` all take an optional
+      target pubkey; the nsec provider threads `expectPubkey` through so a switch unlocks
+      the requested account (not the last-saved one), with the `expectPubkey` guard as a
+      backstop. IndexedDB mirror is now keyed per-pubkey too. Added
+      `listStoredSessionActorPubkeys()`. Tests: `tests/session-actor-multi-account.test.mjs`
+      (7 — per-account resolve, list, clear-one-keeps-others, no-arg default, no-arg wipe,
+      v1→v2 migration, missing-account returns null).
+- [x] **Multiple NIP-46 accounts — DONE 2026-06-30.** The remote-signer session store is
+      now per-user-pubkey (`bitvid:nip46:sessions:v2` = `{ [userPubkeyLower]: session }`),
+      mirroring the nsec store. Several saved NIP-46 accounts each keep their own
+      reconnectable session, so the switcher can move between them. The legacy v1 single
+      slot is kept in sync as the last-connected default (boot restore) and migrated into
+      the map on first read. `readStoredNip46Session` and `getStoredNip46Metadata` take an
+      optional target pubkey; `writeStoredNip46SessionSync` writes both the map (keyed by
+      `userPubkey`) and the v1 default; `clearStoredNip46Session(pubkey)` forgets one
+      account (no-arg wipes all, for logout). `SignerManager.useStoredRemoteSigner({ pubkey
+      })` selects the target account's session and, on access-denial, forgets only that
+      account; the nsec/nip46 providers thread `expectPubkey` through so a switch
+      reconnects the requested account (with the `expectPubkey` guard as a backstop). Added
+      `listStoredNip46SessionPubkeys()`. (`nip46Connector.js` is dead code — the live path
+      is entirely in `SignerManager`.) Tests: `tests/nip46-multi-account.test.mjs` (7).

+      asserts `isDevMode === true` but never sets `globalThis.__BITVID_DEV_MODE_OVERRIDE__`

+
+## Open — rough edges found in hands-on testing (2026-07-01)
+Reported by the maintainer after live testing on `unstable`. Several share a root
+cause with **#36** (a persisted **nsec** session restores the pubkey + UI but NOT the
+in-memory signer after a page reload, because the private key is only
+passphrase-encrypted). Items 51, 56, 57 are all facets of that.
+
+### 51. Shouldn't have to re-"unlock" storage after every refresh (UX / session)
+- [ ] **Symptom:** after a page refresh the user must unlock storage again every time.
+- [ ] **Root cause:** same as **#36** — the nsec signer + unlocked storage master key
+      live only in memory, so a reload drops them. Today the fix (#36) makes the error
+      *actionable* (re-enter passphrase), but the user still has to do it every reload.
+- [x] **DONE 2026-07-01 — opt-in "keep unlocked" cache.** Decision (maintainer):
+      **opt-in** tiers. On a successful nsec unlock the decrypted key is cached in a
+      new `js/nostr/unlockedKeyCache.js`:
+        - **session tier (default, always):** `sessionStorage` — survives refresh /
+          navigation, auto-cleared on tab close. Roughly the same exposure as the
+          in-memory signer, so no more PIN on every reload within a session.
+        - **persistent tier (opt-in checkbox):** the unlock prompt now shows a "Keep
+          me unlocked on this device" checkbox (with an inline unencrypted-at-rest
+          warning); when checked the key is ALSO written to `localStorage` and survives
+          until the user clears site data.
+      `client.restoreUnlockedSigner(pubkey)` re-registers the signer from the cache
+      WITHOUT a passphrase (verifies the key derives to that pubkey; a mismatch
+      forgets it). It's called proactively from `ensureActiveSignerForPubkey` (the
+      auto-login/refresh path) and lazily from `ensureEncryptionCapableSigner` before
+      any prompt — so after a reload the signer is restored silently and every
+      signing/encryption flow (storage, hashtags, DMs, reactions, blocks, subs) just
+      works. Logout / remove-saved-profile forget the cached key
+      (`forgetUnlockedSigner`). Tests: `tests/unlocked-key-cache.test.mjs` (8). Lint +
+      build green.
+- [x] **Storage + NWC inherit the kept-unlocked signer — DONE 2026-07-01.** Storage
+      and NWC don't have their own passphrase: the storage master key and the NWC
+      settings are ENCRYPTED WITH THE SIGNER (nip44/nip04 self-encryption) and unlocked
+      by it. So rather than caching a second secret, both now inherit the kept-unlocked
+      nsec signer. `_initAutoLogin` calls `nostrClient.restoreUnlockedSigner(pubkey)`
+      BEFORE the boot re-login, so the login flow (NWC hydrate, list decrypt) and the
+      existing storage auto-unlock (ProfileStorageController / UploadModal call
+      `storageService.unlock` when a signer is present) all succeed silently on refresh
+      — no passphrase, no manual "Unlock storage". Tied to the signer cache: persists
+      exactly as long as the kept-unlocked key does (session or until site-data clear).
+      (NIP-07/46 profiles no-op — nothing is cached; their extension/remote signer
+      already persists.)
+- [ ] **VERIFY on unstable:** unlock once (box unchecked) → refresh → no PIN, and
+      Storage shows Unlocked + the wallet/NWC connection is live without re-entry;
+      close the tab + reopen → PIN again. Check the box → close/reopen the browser →
+      still no PIN and storage/NWC still ready; Log out or clear site data → PIN again.
+- [x] **"Lock this device" control — DONE 2026-07-01.** A footer button in the profile
+      modal (desktop + mobile), shown only when the active account has a cached
+      "keep unlocked" key to forget (`app.isSessionKeptUnlocked`). Clicking it runs
+      `app.lockKeptUnlockedSession(pubkey)`, which re-locks everything the signer
+      unlocks in one action: forgets the cached key (both tiers → future reloads
+      re-prompt), drops the in-memory signer (`logoutSigner` → the current session
+      re-locks now), `storageService.lock(pubkey)`, and `nwcSettingsService.clearCache()`.
+      Visibility refreshes on `renderSavedProfiles` + `selectPane`. Tests:
+      2 in `tests/profile-modal-controller.test.mjs` (visibility gate + click locks the
+      active pubkey). Lint + build green.
+- [ ] **Follow-up (optional):** surface whether the current session is *persistently*
+      remembered (disk vs session tier) in the UI, and consider a "keep unlocked" toggle
+      in the storage/wallet panes for users who set it up there rather than via a prompt.
+
+### 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`.
+
+### 53. Channel-profile link in the video player modal doesn't work (BUG)
+- [ ] Clicking the channel/creator link inside the video player modal does nothing
+      (should navigate to that author's channel profile view). Audit the modal's
+      channel-link handler (`js/ui/videoModal*` / the author byline) — likely a missing
+      or wrong nav callback (compare with the working channel links in the grid cards).
+
+### 54. Like / dislike buttons in the video player modal don't work (BUG)
+- [ ] The reaction (like/dislike) buttons in the player modal are unresponsive / don't
+      persist. Audit `reactionController` wiring into the video modal (event binding,
+      active-signer availability, publish path). Note: reactions require signing — verify
+      this isn't another "lost signer after refresh" (#57) surfacing as a dead button; if
+      so, prompt to unlock rather than silently no-op.

+      now runs the `ensureEncryptionCapableSigner` gate (`need:"sign"`) before
+      publishing, so a reloaded nsec session re-unlocks with one passphrase prompt
+      instead of the reaction silently failing (rolled-back button + generic error).
+      Tests: `tests/reaction-signer-gate.test.mjs`. **Still VERIFY on unstable** whether
+      any residual dead-button behavior remains (event binding / pointer availability),
+      which would be a separate wiring bug from the signer issue.
+
+### 55. Video-grid event caching — faster loads, cache-first + merge-new (PERF / UX)
+- [ ] **Channel-profile grid still loads slowly.** Even after the coalescing + relay
+      timeout + parity-seed fix, the channel wall streams in slowly. Cache that channel's
+      events so revisits render instantly.
+- [ ] **Generalize to every grid:** cache the events behind each video grid (feed tabs +
+      channel walls) so they render from cache immediately, then refresh in the
+      background and **merge in only new events** (don't blank + re-fetch). Fresh content
+      still matters — proposed balance: **cache-and-refresh simultaneously**, appending
+      new events as they arrive, with an explicit **pull-to-refresh / refresh button**
+      for a forced re-fetch. Decide cache store (in-memory vs IndexedDB via
+      `js/state/cache.js`) + a staleness/TTL policy.
+- [ ] **Cache media too:** thumbnails and profile images/banners should be cached (browser
+      cache headers / a warm cache / persistent store) so they don't reload from scratch
+      on every visit. Cross-ref `js/channelProfile.js` and the card renderers.
+
+### 56. Upload & edit modals: prompt to unlock storage (PIN popup), don't just error (UX)
+- [ ] When storage is locked, the **upload** and **edit** modals should open the
+      passphrase/PIN unlock popup instead of surfacing a raw error — for **both** the
+      video-file upload and the **thumbnail** upload. **#36** already added this
+      auto-open-login unlock for the **upload** modal; extend the same treatment to the
+      **edit** modal and the **thumbnail** upload path.
+- [ ] Combine with **51**: once unlocked, cache the state so the user isn't re-prompted
+      on every upload/refresh. "Both would be nice" — actionable prompt AND cached unlock.
+
+### 57. nsec / NIP-46 accounts: encryption ops fail after refresh — re-prompt, don't blanket-error (BUG)
+- [ ] **Symptom:** adding/editing a hashtag on an **nsec**-logged-in account errors with
+      *"Connect a Nostr signer that supports encryption before managing hashtag
+      preferences."* Same class blocks other NIP-44/encryption list ops (subscriptions,
+      blocks, DMs) after a reload.
+- [ ] **Root cause (likely #36):** the reload dropped the in-memory nsec signer, so
+      `nip44Encrypt`/`nip44Decrypt` aren't available even though the user "looks" logged
+      in. The guard then emits a blanket "connect a signer that supports encryption."
+- [ ] **Fix intent:** ALL signing/encryption functions must work across ALL signer types
+      (nsec / NIP-46 / NIP-07). When the op needs a locked nsec key, **prompt to re-enter
+      the PIN/passphrase to re-unlock the signer** (reuse #36's unlock flow) instead of a
+      dead-end error. Cross-ref **#48** (fluent switching) and the account-switch refresh
+      work (commit `87af650b`). Audit every "signer that supports encryption" guard and
+      route it to the unlock prompt when a saved nsec key exists for the active pubkey.
+- [x] **Shared gate built + hashtags wired — DONE 2026-07-01.** New reusable
+      `app.ensureEncryptionCapableSigner({ pubkey, need, promptMessage })`
+      (`js/app.js`, pure branching in `js/nostr/ensureSignerDecision.js`): checks the
+      active signer's capabilities; if it can't encrypt/sign AND a **matching** locked
+      nsec key exists for the account, prompts once for the passphrase and re-unlocks
+      the signer app-wide via `unlockStoredSessionActor` (one unlock re-enables every
+      flow until the next reload). Never unlocks a different account's key
+      (pubkey-mismatch guard). Exposed to the profile modal as
+      `services.ensureEncryptionCapableSigner`. **Hashtag add/edit** now routes through
+      it (`ProfileHashtagController.persistHashtagPreferences`): a cancelled prompt
+      silently aborts, a bad passphrase shows its own toast, and publish never runs
+      until the signer is confirmed. Tests: `tests/ensure-signer-decision.test.mjs` (9),
+      + 2 wiring tests in `tests/profile-modal-controller.test.mjs`. Lint + build green.
+- [x] **Fast-follows wired — DONE 2026-07-01.** All remaining signing/encryption
+      call sites now route through `ensureEncryptionCapableSigner`, short-circuiting
+      only on the user-driven outcomes (cancel / bad-passphrase) so every other case
+      still falls through to the flow's own error handling:
+        - **Reactions (#54):** `ReactionController.handleReaction` gates before the
+          optimistic update with `need:"sign"` (kind-7 reactions don't need encryption).
+          Tests: `tests/reaction-signer-gate.test.mjs` (3).
+        - **Blocks:** `authSessionCoordinator.handleProfileBlocklistMutation`
+          (`need:"encrypt"`, NIP-04 mute/block lists).
+        - **Subscriptions:** the channel-profile Subscribe/Unsubscribe toggle
+          (`js/channelProfile.js`, `need:"encrypt"`, kind-30000).
+        - **DM send:** both composers — `handleSendProfileMessage` and
+          `handleDmAppShellSendMessage` (`need:"encrypt"`, NIP-17/NIP-04).
+      Lint + build + related suites (decision, reaction, DM, profile-modal, switch)
+      green.
+- [ ] **VERIFY on unstable:** with an nsec account, reload, then (a) add a hashtag,
+      (b) like/dislike a video, (c) block/unblock a creator, (d) subscribe to a channel,
+      (e) send a DM — each should show ONE passphrase prompt (not a blanket error), then
+      work; the single unlock should cover the rest until the next reload.
