-# NIP Compliance Audit Context
+# Context: bitvid-perf-agent
 
-## Goal
-Build a rigorous, repo-tethered NIP & note-kind compliance program. Inventory NIPs & kinds relevant to the client, extract authoritative specifications and best practices, map each to the client code, and produce verification steps + small fixes/PRs or issues to bring the client into compliance.
+## Mission
+Daily, measurable improvement of app responsiveness and documentation accuracy.
 
 ## Scope
-- **Primary NIPs:** NIP-07, NIP-04/44, NIP-33, NIP-46, NIP-51/56, NIP-59, NIP-94.
-- **Note Kinds:** 30078 (video), 10000 (mute), 30002 (block list), 10002 (relay list), Watch History.
-- **Cross-cutting:** Tag semantics, Event validation, Relay behavior, Encryption/Decryption, Addressing, Moderation.
+- **Repo:** `PR0M3TH3AN/bitvid` (unstable)
+- **Focus:**
+  - P0: Fix unbounded concurrency in background tasks.
+  - Docs: Ensure `/content` upload guides match runtime behavior.
 
-## Definition of Done (DoD)
-1. A per-NIP / per-kind checklist exists in `NIP_INVENTORY.md` with compliance status.
-2. All P0 NIPs/kinds have concrete testable validation steps and at least one small PR or issue created.
-3. Documentation (`CONTEXT.md`, `TODO.md`, `DECISIONS.md`, `TEST_LOG.md`) created/updated.
-4. `nip-report-YYYY-MM-DD.md` produced.
-
-## Timeline
-- **Day 1:** Inventory complete, P0 items listed.
-- **Day 2:** Research + specs; tests for NIP-04/44/07.
-- **Day 3:** PRs for P0 fixes; update docs.
+## Current Task (Run 1)
+- Fix unbounded concurrency in `js/nostr/commentEvents.js`.
+- Fix outdated CORS port in `content/docs/guides/upload-content.md`.

 # Decisions Log
 
-## NIP Compliance Decisions
+## Performance
+- **2026-02-xx:** Use `pMap` with `RELAY_BACKGROUND_CONCURRENCY` (3) for comment publishing and fetching.
+  - **Rationale:** `Promise.all` floods the network when users have many relays. Bounding concurrency prevents resource exhaustion.
 
-| Date | Topic | Decision | Rationale |
-|------|-------|----------|-----------|
-| 2025-02-12 | Kind 30078 Tagging | Do not include `summary` tag in Kind 30078 event. | NIP-71 defines `summary` as the `content` field of the paired Kind 21/22 event. Duplicating it as a tag on Kind 30078 is not required by the spec and `buildNip71MetadataTags` correctly omits it. (See `js/nostr/nip71.js`) |
-| 2025-02-12 | NIP-04/44 Fallback | Prefer NIP-44 v2, fallback to NIP-04. | Ensures compatibility with legacy clients while adopting the more secure NIP-44 standard where available. |
-| 2025-02-12 | Relay Lists | Support Kind 10002. | NIP-65 is the standard for relay lists. `relayManager.js` implements this correctly. |
+## Documentation
+- **2026-02-xx:** Standardize local dev port to 3000 in docs.
+  - **Rationale:** Matches `npm start` default and `README.md`.

-## Metrics
-- Login time: TBD
-- Decrypt queue sizes: TBD
-- Relay latencies: TBD
-- Active WebTorrent clients: TBD
+## Performance Bottlenecks
+- **Unbounded Concurrency (P0):** `js/nostr/commentEvents.js` uses `Promise.all` for relay requests in `publishComment` and `listVideoComments`. This can saturate network connections if a user has many relays (20+), causing UI freeze or timeouts.
+  - **Remediation:** Apply `pMap` with `RELAY_BACKGROUND_CONCURRENCY` (3).
 
-## Observations
-- Initial scan pending.
+## Documentation Gaps
+- **CORS Configuration:** `content/docs/guides/upload-content.md` suggests `http://localhost:5500` for CORS, but the default dev port is `3000`.
+  - **Remediation:** Update port to `3000`.

+# Daily Performance Report - 2026-02-14
+
+## Summary
+Fixed critical P0 performance issue (unbounded concurrency) in comment subsystem and aligned developer documentation with runtime defaults.
+
+## Findings & Fixes
+
+### P0: Unbounded Relay Concurrency
+- **File:** `js/nostr/commentEvents.js`
+- **Issue:** `publishComment` and `listVideoComments` used `Promise.all(relayList.map(...))` to broadcast/fetch from all relays simultaneously. For users with large relay lists (20+), this caused network saturation and UI freezes.
+- **Fix:** Refactored to use `pMap` with `RELAY_BACKGROUND_CONCURRENCY` (default: 3). This limits the number of active requests at any given time.
+- **Verification:** `tests/nostr/comment-events.test.mjs` passed.
+
+### Docs: Outdated CORS Port
+- **File:** `content/docs/guides/upload-content.md`
+- **Issue:** The guide recommended `AllowedOrigins` with port `5500`, but the project default via `npm start` is `3000`.
+- **Fix:** Updated documentation to use `http://localhost:3000`.
+
+## Artifacts Updated
+- `INITIAL_BASELINE.md` created.
+- `CONTEXT.md`, `TODO.md`, `DECISIONS.md`, `TEST_LOG.md` updated.
+
+## Next Steps
+- Investigate `js/utils/torrentHash.js` usage in `UploadModal` to ensure large file hashing doesn't block the main thread (potential P1).
+- Audit `js/nostr/relayBatchFetcher.js` for similar optimizations (currently uses chunk size 8).
