 ## Testing
 
-Continuous integration runs CSS linting/builds, the Playwright kitchen-sink snapshots, and the Node-based unit tests on every push.
+Continuous integration runs CSS linting/builds, the DM unit/integration suites, the Playwright kitchen-sink snapshots, headless E2E flows, and the Node-based unit tests on every push.
 Before pushing, run `npm run build` locally so the Tailwind bundle regenerates.
 Pair that with `npm run test:unit` for application logic changes and
 `npm run test:visual` for presentation updates to mirror the CI surface area.
+For DM-specific changes, also run `npm run test:dm:unit` and
+`npm run test:dm:integration` to cover the direct message flows.
+Use `npm run test:e2e` to execute the headless Playwright journeys in `tests/e2e`.

+read alongside the protocol references in `docs/nips/17.md`, `docs/nips/59.md`,
+and `docs/nips/44.md`.

+## Privacy layers: rumor → seal → gift wrap
+
+When privacy mode is enabled, bitvid uses the NIP-17 pipeline:
+
+1. **Rumor (kind 14 / 15)**: a plaintext DM or attachment payload is created.
+2. **Seal (kind 13)**: the rumor is encrypted with NIP-44 to produce a sealed
+   event signed by the sender.
+3. **Gift wrap (kind 1059)**: the seal is encrypted again with NIP-44 using a
+   freshly generated ephemeral keypair. The outer wrap is what relays receive.
+
+This layered approach hides the sender/recipient metadata and message timing
+from public relays while still allowing the receiver to unwrap the message.
+bitvid randomizes timestamps for seals and wraps to reduce correlation, and
+publishes a sender copy of the wrap so the sender can sync their own history.
+
+## Relay hint selection
+
+Relay hints decide where gift-wrapped NIP-17 events are published. Selection
+uses the following priority order:
+
+1. **Explicit hints** – If the caller provides `recipientRelayHints` or
+   `senderRelayHints`, those are used immediately.
+2. **Recipient discovery** – Otherwise, the client queries the configured read
+   relays for the recipient's `kind:10050` relay list and uses any `relay` tags
+   it finds.
+3. **Fallback relays** – If no relay list is found, the client falls back to the
+   configured write relays (or the default relay list), and flags the selection
+   as a privacy fallback.
+
+This logic is shared by the DM service helper `resolveDmRelaySelection()` and
+by `NostrClient.sendDirectMessage()` when `useNip17` is enabled.
+
+### Legacy NIP-04 relay selection
+
+When privacy mode is disabled, bitvid sends a traditional kind `4` DM:
+
+- It attempts to load the recipient's NIP-65 relay list (`kind:10002`) from the
+  configured read relays.
+- If no relay list is available, it falls back to the configured write relays
+  (or the default relay list).
+
+The final relay set is where the signed NIP-04 ciphertext is published.
+
+## User controls that affect privacy
+
+### Privacy toggle (NIP-17 vs NIP-04)
+
+The DM composer exposes a privacy toggle that switches between NIP-04 and
+NIP-17 delivery. When the toggle is enabled, the UI explains that NIP-17
+gift-wraps the message so relays only see the wrapper and relay hints.
+
+### Relay hint management
+
+Users can curate their own DM relay hints list in the profile modal. The UI
+lets them add and remove WSS relay URLs and publish the resulting list as a
+`kind:10050` event. This list is what other clients query during the relay
+selection phase above.
+
+### Read receipts & typing indicators
+
+Additional DM privacy toggles (read receipts and typing indicators) live in the
+same profile modal and persist to local state. Turning them off reduces
+metadata leaks by preventing extra ephemeral events from being sent.

 # NostrClient Overview

+`NostrClient` (`js/nostr/client.js`) is the central controller for all Nostr network interactions and state management in the application. It acts as a facade over `nostr-tools`, managing connections to multiple relays, signing events, and maintaining the local application state.
 
-## Key Responsibilities
+## Responsibilities
 
-1.  **Connection Management**: Maintains a pool of connections to multiple relays (`SimplePool`).
-2.  **State Management**: Tracks video events, deduplicates them, and manages deletions via tombstones.
-3.  **Caching**: Implements a "stale-while-revalidate" strategy using IndexedDB (with localStorage fallback) to restore UI state immediately upon load.
-4.  **Event Publishing**: Orchestrates the signing and broadcasting of complex event chains (Video Note -> NIP-94 Mirror -> NIP-71 Metadata).
-5.  **Signer Abstraction**: Unifies NIP-07 (Extension), NIP-46 (Remote/Bunker), and Local (nsec) signing under a single interface.
-6.  **Video History**: Reconstructs the edit history of videos using `videoRootId` and `d` tags.
+1.  **Connection Management**: Maintains a pool of connections to configured Nostr relays. It handles initialization, reconnection, and error logging.
+2.  **Event Publishing**: Handles the creation, signing, and broadcasting of various Nostr event kinds (Video Post: 30078, Reaction: 7, Comment: 1, etc.). It supports NIP-07 (Extension), NIP-46 (Remote/Bunker), and NIP-01 (Local nsec) signers.
+3.  **State Management**:
+    *   `allEvents`: A raw map of all fetched video events (Kind 30078), preserving history.
+    *   `activeMap`: A derived map containing only the *latest* version of each video, deduplicated by `videoRootId` or `d` tag. This is the source of truth for the UI.
+    *   `rawEvents`: A cache of the exact raw JSON events from relays, used for signature verification and republishing.
+    *   `tombstones`: Tracks deletion timestamps to prevent deleted events from reappearing.
+4.  **Caching**: Implements a dual-layer cache (`IndexedDB` + `localStorage`) to persist `activeMap`, `allEvents`, and `tombstones`. This allows the app to restore its state instantly on load ("stale-while-revalidate").
+5.  **Video Lifecycle**: Manages the full lifecycle of a video post: Publish -> Edit (new event with same `d` tag) -> Revert (new event, same `d`, deleted flag) -> Delete (Kind 5).
 
-## Architecture & State
+## Key Concepts
 
-The client maintains several internal maps to manage state:
+### Active Video Logic
+Nostr is an append-only protocol. Edits are new events. `NostrClient` implements "latest-wins" logic to present a coherent view:
+- **Identifier**: Videos are identified by a `videoRootId` (in the content) or a NIP-33 `d` tag.
+- **Resolution**: When a new event arrives, the client checks if it's newer than the current active version in `activeMap`. If so, it replaces the entry.
+- **Deletions**: If an event has `deleted: true` or is a Kind 5 deletion, it is removed from `activeMap`, and a tombstone is recorded.
 
-*   `allEvents`: A raw map of all fetched video events (key: event ID).
-*   `activeMap`: A derived map containing only the *latest* version of each video, keyed by a stable identifier (`videoRootId` or addressable pointer).
-*   `rawEvents`: A cache of the exact raw JSON events from relays, used for signature verification and re-publishing.
-*   `tombstones`: Tracks timestamps of deletion events to prevent "zombie" events (deleted events reappearing from slow relays) from resurfacing.
+### Buffering & Debouncing
+To handle high volumes of events (e.g., during initial relay dump), `subscribeVideos` uses a buffering strategy:
+1.  Incoming events are pushed to `eventBuffer`.
+2.  A flush is scheduled with a short debounce (e.g., 75ms).
+3.  On flush, the batch is processed: validation, state updates, and UI notification.
+This prevents UI thrashing.
 
-### Caching Strategy (`EventsCacheStore`)
+### Tombstones
+Because relays are eventually consistent, a deleted event might arrive *after* a deletion command.
+- `tombstones` map `activeKey` -> `timestamp`.
+- If an incoming event is older than the tombstone for its key, it is ignored (`applyTombstoneGuard`).
 
-To ensure instant load times, the client persists its state to IndexedDB (`bitvid-events-cache`).
-*   **Snapshot**: On a debounced timer (or idle callback), the current state (`allEvents`, `tombstones`) is serialized.
-*   **Fingerprinting**: Events are fingerprinted to avoid writing unchanged data to the DB.
-*   **Restore**: On `init()`, the client loads the latest snapshot into memory, allowing the UI to render before any network requests complete.

 ```
 
-### 2. Video Subscription (`subscribeVideos`)
+## When to Modify
 
-To prevent UI thrashing during high-volume event ingress (e.g., initial flood from relays), the client uses a **buffering and debouncing** strategy.
-
-1.  **Buffer**: Incoming events are pushed to `eventBuffer` instead of being processed immediately.
-2.  **Debounce**: A flush timer is scheduled (75ms).
-3.  **Flush**: When the timer fires, the entire buffer is processed:
-    *   Events are validated and converted.
-    *   `activeMap` is updated (latest-wins logic).
-    *   `onVideo` callback is fired once with the batch updates.
-    *   Cache persistence is scheduled.
-
-### 3. Publishing a Video (`publishVideo`)
-
-Publishing is a multi-step process ensuring compatibility and discoverability.
-
-1.  **Video Note (Kind 30078)**: The core content (magnet, infohash, metadata) is signed and published. A unique `videoRootId` is generated for new videos.
-2.  **NIP-94 Mirror (Kind 1063)**: If a direct HTTP URL is provided, a file header event is published to point to the hosted file.
-3.  **NIP-71 Metadata (Kind 22/21)**: Addressable metadata tags are published to support categorization/grouping without modifying the immutable video note.
-
-### 4. Remote Signer Handshake (`connectRemoteSigner`)
-
-For NIP-46 (Nostr Connect), the client implements a full handshake flow:
-
-1.  **Ephemeral Key**: Generates a local key pair for the session.
-2.  **Handshake**: Publishes a Kind 24133 (`NIP46_RPC_KIND`) event to the relay.
-3.  **Wait**: Listens for an acknowledgment or `auth_url` challenge from the signer.
-4.  **Session**: Once connected, stores the session metadata to allow auto-reconnection.
-
-## Why it works this way
-
-*   **Buffering**: essential for performance. React rendering cycles are expensive; updating state for every single event in a 5000-event relay dump would freeze the browser.
-*   **Tombstones**: essential for eventual consistency. Relays are distributed and can be out of sync. If a user deletes a video, we must remember that deletion timestamp so a slow relay doesn't "undelete" it by serving the old event later.
-*   **Dual-Layer Cache**: IndexedDB is asynchronous and large-capacity; localStorage is synchronous but small. We use IndexedDB for the bulk data but keep a fallback for environments where IDB might be flaky or slow to initialize.
-
-## When to change
-
-*   **Refactor `EventsCacheStore`**: If moving to a more robust state management library (like RxDB or dedicated worker), this logic should be extracted.
-*   **New Event Kinds**: If the video data model changes (e.g., V4 schema), `convertEventToVideo` and `publishVideo` will need updates.
-*   **Signer upgrades**: As NIP-46 evolves (e.g., Bunker standards), the handshake and connection logic in `nip46Client.js` (and its orchestration here) will need adjustment.
+- **Adding a new Event Kind**: If the app needs to support a new type of interaction (e.g., playlists), add the handling logic here and in `js/nostrEventSchemas.js`.
+- **Changing Caching Strategy**: Modify `EventsCacheStore` or `persistLocalData` if the caching requirements change.
+- **Updating Signing Logic**: Changes to NIP-07 or NIP-46 integration should be carefully reviewed here.

+# SigningAdapter guide
+
+`SigningAdapter` is the lightweight interface bitvid uses to sign direct-message
+payloads and message metadata without depending on a specific auth provider.
+The canonical implementations live in `js/auth/signingAdapter.js`, and callers
+such as `NostrClient.sendDirectMessage()` and the DM composer accept a
+`signingAdapter` option so they can work with NIP-07 extensions, remote signers,
+or test doubles.
+
+## Interface contract
+
+A `SigningAdapter` is an object with the following async methods:
+
+- `getPubkey()` → resolves the hex public key that should be used as the DM
+  author.
+- `getDisplayName()` → optional display name string for UI metadata.
+- `signEvent(unsignedEvent)` → returns a fully signed Nostr event object.
+- `signMessage(message)` → returns a signature for an arbitrary string.
+
+`signEvent()` is required for DM publishing; `signMessage()` is optional but is
+used by the DM composer to attach a signature to the outgoing payload metadata.
+
+## Implementing a new adapter
+
+1. **Normalize the pubkey**: resolve and return a lowercased hex pubkey from
+   `getPubkey()`. The NIP-07 adapter does this by delegating to
+   `window.nostr.getPublicKey()` and normalizing the result.
+2. **Provide signing primitives**:
+   - `signEvent()` must return an event with `id` and `sig` populated.
+   - `signMessage()` should return a stable signature string for the message
+     body when you need message-level signatures (for example, the DM composer
+     includes this for UI payloads).
+3. **Expose a type label**: include a `type` field (for example `nip07`, `dev`,
+   or `test`) to make debugging easier.
+
+Reference implementations:
+
+- `createNip07SigningAdapter({ extension })` uses a browser extension signer.
+- `createEphemeralDevSigningAdapter()` generates a local, throwaway keypair for
+  development flows.
+- `createTestSigningAdapter()` returns deterministic signatures for tests.
+
+## Testing a SigningAdapter
+
+### Unit tests
+
+For Node-based tests, use `createTestSigningAdapter()` so signatures are stable
+and deterministic. You can pass it directly to `NostrClient.sendDirectMessage()`
+through the `options.signingAdapter` field to avoid relying on active signers:
+
+```js
+import { createTestSigningAdapter } from "../js/auth/signingAdapter.js";
+import { nostrClient } from "../js/nostrClientFacade.js";
+
+const adapter = createTestSigningAdapter({
+  pubkey: "f".repeat(64),
+});
+
+const result = await nostrClient.sendDirectMessage(
+  "npub...",
+  "hello",
+  null,
+  { signingAdapter: adapter }
+);
+```
+
+Assertions can then verify that `result.ok` is `true` and that the signed event
+was built with the adapter's pubkey and signatures.
+
+### Manual smoke checks
+
+For browser-only checks, wire the adapter into the DM composer by passing it in
+as the `signingAdapter` prop. The composer will call `getPubkey()`,
+`getDisplayName()`, and `signMessage()` while building the outgoing payload
+object so you can inspect the resulting metadata in your handler.
+
+## Usage reminders
+
+- When the signer does **not** implement NIP-44 encryption, NIP-17 sends are
+  blocked; keep the privacy toggle disabled until encryption is available.
+- Always surface errors from `getPubkey()` or `signMessage()` to the caller so
+  the UI can display a meaningful failure state.

+# Repost Comment Visibility Bug
+
+This reproducer demonstrates an issue where comments made on an original video are not visible when viewing that video via a Repost (Kind 6).
+
+## The Bug
+
+When viewing a repost, the application often passes the Repost event's metadata (Kind 6, Reposter Pubkey) along with the *Original Video's ID* to the comment system.
+
+The `CommentThreadService` (via `normalizeCommentTarget`) creates a filter descriptor based on this input. It expects comments to tag the **Repost** (Kind 6) and the **Reposter**.
+
+However, comments are almost always made on the **Original Video** (Kind 30078), tagging the **Original Author**.
+
+Because `isVideoCommentEvent` enforces strict matching of `rootKind` and `rootAuthor` against the descriptor, it rejects the valid comments on the original video, resulting in an empty comment section.
+
+## Running the Reproducer
+
+```bash
+node --import ./tests/test-helpers/setup-localstorage.mjs examples/reproducers/2-repost-comment-visibility-bug/reproduce_issue.js
+```
+
+## Expected Output (Failure)
+
+```
+Input Target: { ... videoKind: 6 ... }
+Generated Descriptor: { ... rootKind: '6' ... }
+...
+Is Comment Visible? false
+FAIL: Comment on original video is NOT visible when viewing repost.

+ * When a video is a repost (Kind 6), the UI may pass the Repost event's metadata
+ * (kind: 6, author: reposter) along with the Original Video's ID to the comment service.
+ *
+ * `normalizeCommentTarget` uses this metadata to build a descriptor that expects comments
+ * to tag the Repost event (Kind 6) and the Reposter.
+ *
+ * However, comments are typically made on the Original Video (Kind 30078), tagging the
+ * Original Author and Original Kind.
+ *
+ * `isVideoCommentEvent` then filters out these valid comments because they don't match
+ * the "expected" rootKind/rootAuthor (which are set to Repost details).
+ *
+ * EXPECTED BEHAVIOR:
+ * Comments on the original video should be visible even when viewing the repost.
+ * The descriptor should normalize to the Original Video's metadata if the ID belongs to it,
+ * OR `isVideoCommentEvent` should be smart enough to handle this mismatch.
