chore(protocol): update inventory and status for NIP-04/NIP-42

- Updated PROTOCOL_INVENTORY.md to mark NIP-04 and NIP-42 as Not Implemented.
- Generated reports/protocol/protocol-report-2026-02-24T02-12-00Z.md.
- Created run artifacts (CONTEXT, DECISIONS, TODO, TEST_LOG).
- Created task log task-logs/daily/2026-02-24T02-12-00Z__protocol-research-agent__completed.md.

+## Key findings
+- NIP-04 (Encrypted Direct Message) and NIP-42 (Authentication) are not implemented in the codebase.
+- Relay health probes use custom Kind 27235 via raw WebSocket connections.
+
+## Patterns / reusable knowledge
+- `src/relay-health.mjs` contains isolated WebSocket logic using `nostr-tools/pure`.
+
+## Warnings / gotchas
+- `PROTOCOL_INVENTORY.md` statuses should be verified against code, not just assumed from lack of documentation.

+# Protocol Compliance Report — 2026-02-24
+
+**Agent:** protocol-research-agent
+**Run ID:** 2026-02-24T02:12:00Z
+**Date:** 2026-02-24
+
+## Executive Summary
+No new protocol risks or unknown protocol usages were identified. The repository remains compliant with its core NIPs (01, 33, 40, 78). Status for NIP-04 and NIP-42 was updated from "Unknown" to "Not Implemented" after code verification confirmed absence of usage.
+
+## Findings
+
+### Nostr (NIPs)
+- **NIP-01:** Compliant. Verified usage of `nostr-tools` v2.23.1 and `nostr-tools/pure` exports in `src/relay-health.mjs`.
+- **NIP-33:** Compliant. `src/lock-ops.mjs` correctly implements parameterized replacement via `d` tags.
+- **NIP-40:** Compliant. `src/lock-ops.mjs` parses expiration tags. `src/cmd-complete.mjs` intentionally omits them for permanent completion records.
+- **NIP-78:** Compliant. Core locking mechanism relies on Kind 30078 (Application Data).
+- **NIP-04 (Encrypted DM):** Not Implemented. Confirmed no usage in `src/`.
+- **NIP-42 (Authentication):** Not Implemented. Confirmed no AUTH challenge handling in `src/`.
+
+### Other Protocols
+- **WebSocket:** Direct usage in `src/relay-health.mjs` for deep health probes (Kind 27235). This custom protocol remains isolated and compliant with intended design.
+- **HTTP:** Dashboard server in `src/dashboard.mjs` uses standard Node.js `http` module. Auth is basic token comparison, not a standardized protocol.
+
+## Recommendations
+- Maintain current pinned versions of `nostr-tools` and `ws` to ensure stability.
+- Continue omitting NIP-42 unless relay authentication becomes a requirement for private deployments.

+## Update NIP statuses
+**Decision:** Mark NIP-04 and NIP-42 as "Not Implemented".
+**Rationale:** Codebase scan confirmed complete absence of implementation for these specs. "Unknown" status was inaccurate.
