Implemented `waitForNip07Extension` polling in `js/nostr/client.js` to address race conditions where `window.nostr` is not immediately available. Updated `js/nostr/nip07Permissions.js` with the polling logic and added unit tests.

/**
|
|
* NostrClient
|
|
*
|
|
* The central controller for all Nostr network interactions and state management.
|
|
* For a high-level overview, see `docs/nostr-client-overview.md`.
|
|
*
|
|
* Responsibilities:
|
|
* - Connection Management: Maintains the connection pool to Relays.
|
|
* - Event Publishing: Handles signing and broadcasting events (Kind 0, 1, 30078, etc.).
|
|
* - State Management:
|
|
* - `allEvents`: A raw map of all fetched video events.
|
|
* - `activeMap`: A derived map containing only the *latest* version of each video (deduplicated by `videoRootId`).
|
|
* - `rawEvents`: A cache of the exact raw JSON events from relays (for signature verification).
|
|
* - Caching: Implements a dual-layer cache (IndexedDB + localStorage) to restore app state instantly on load.
|
|
* - Signer Management: Orchestrates NIP-07 (Extension), NIP-46 (Remote/Bunker), and NIP-01 (Local nsec) signers.

|

* Process:
|
|
* 1. **Parse**: Decodes the `nostrconnect://` or `bunker://` URI.
|
|
* 2. **Handshake (if needed)**: If the URI is a "connect" request (no target pubkey yet),
|
|
* it publishes an ephemeral event and waits for the signer to "ack".
|
|
* 3. **Connect**: Once the remote pubkey is known, sends a `connect` RPC command.
|
|
* 4. **Authorize**: Handles any `auth_url` challenges if the signer requires out-of-band approval.
|
|
* 5. **Session**: Stores the session metadata locally (if `remember: true`) to allow auto-reconnect.

* Fetches a list of events incrementally from multiple relays, respecting `lastSeen` timestamps per relay.
|

*
|
|
* **Optimization Strategy:**
|
|
* - Checks `SyncMetadataStore` for the last known `created_at` timestamp for this query on each relay.
|
|
* - If a timestamp exists, it requests `since: lastSeen + 1` to fetch only new items.
|
|
* - If the incremental fetch fails (or returns nothing when we expected updates), it falls back to a full fetch.
|
|
* - Updates the `SyncMetadataStore` with the new max `created_at` on success.
|
|
*
|
|
* **Concurrency:**
|
|
* - Batches relay requests in chunks of 4 to avoid saturating network connections.
|
|
*
|
|
* @param {object} params
|
|
* @param {number} params.kind - The event kind to fetch (e.g. 10000 for mute list).
|
|
* @param {string} params.pubkey - The author's pubkey.
|
|
* @param {string} [params.dTag] - Optional d-tag for addressable events (NIP-33).
|
|
* @param {string[]} [params.relayUrls] - List of relays to query. Defaults to client's configured relays.
|
|
* @param {function} [params.fetchFn] - Custom fetch function (mocks or specialized logic). Defaults to `pool.list`.
|
|
* @returns {Promise<import("nostr-tools").Event[]>} Deduplicated list of events found across all relays.

/**
|
|
* Subscribes to Kind 30078 video events from relays using a buffered stream.
|
|
*
|
|
* **Why Buffer?**
|
|
* Relays often send bursts of events (e.g., historical dumps or new floods).
|
|
* Processing every single event immediately would cause layout thrashing and UI lag.
|
|
*
|
|
* **The Algorithm:**
|
|
* 1. **Buffer**: Push all incoming events into `eventBuffer`.
|
|
* 2. **Debounce**: Schedule `flushEventBuffer` to run after 75ms of silence or inactivity.
|
|
* 3. **Batch Process**:
|
|
* - Convert events to internal Video objects.
|
|
* - Filter out invalids or duplicates.
|
|
* - Apply "Last-Write-Wins" logic against `activeMap`.
|
|
* - Notify the UI (`onVideo`) once per batch.
|
|
* 4. **Persist**: Save the batch to IndexedDB to warm up the cache for next reload.
|
|
*
|
|
* **Invariants:**
|
|
* - `activeMap` always holds the latest valid version of a video.
|
|
* - Deleted events (Tombstones) are never surfaced to `onVideo`.
|
|
*
|
|
* @param {function(object): void} onVideo - Callback fired when new valid videos are processed. Receives the `Video` object.
|
|
* @param {{ since?: number, until?: number, limit?: number }} [options] - Filter options.
|
|
* @returns {import("nostr-tools").Sub} The subscription object. Call `unsub()` to stop.

|
* Fetches and reconstructs the full edit history of a video.
|
|
*
|
|
* **The Problem:**
|
|
* Nostr events are immutable. "Editing" a video creates a NEW event.
|
|
* We need to find all previous versions to show a history log or allow reverting.
|
|
*
|
|
* **The Linking Logic:**
|
|
* 1. **Modern**: Versions share a `videoRootId` field in their content.
|
|
* 2. **NIP-33**: Versions share the same `d` tag.
|
|
* 3. **Legacy**: Older versions might only be linked by the `d` tag or lack a root pointer entirely.
|
|
*
|
|
* **Algorithm:**
|
|
* 1. **Local Scan**: Search `allEvents` for any event matching the target's `videoRootId` OR `d` tag.
|
|
* 2. **Root Recovery**: If the `videoRootId` refers to an event we don't have, fetch it specifically (to establish the timeline start).
|
|
* 3. **Relay Query**: If local history is sparse (<= 1 version), query relays for all events with the same `d` tag.
|
|
* 4. **Merge & Sort**: Combine all findings, filter out unrelated events, and sort by `created_at` descending.
|
|
*
|
|
* @param {object} video - The target video to find history for.
|
|
* @returns {Promise<object[]>} A promise resolving to an array of Video objects (Newest -> Oldest).
