+# Protocol Inventory
+
+This file tracks external protocol specifications and libraries used in this repository, their implementation points, and compliance status.
+
+## Nostr (NIPs)
+
+| Protocol / Spec | Implementation Points | Compliance Status | Notes |
+| :--- | :--- | :--- | :--- |
+| **NIP-01** (Basic Protocol) | `src/lib.mjs`, `src/lock-ops.mjs` | Compliant | Uses `nostr-tools` for event creation, signing, and relay communication. |
+| **NIP-04** (Encrypted Direct Message) | N/A | Unknown | Not explicitly used in lock logic, but mentioned in test prompts. |
+| **NIP-42** (Authentication) | N/A | Unknown | Not currently implemented in lock logic. |
+| **NIP-33** (Parameterized Replaceable Events) | `src/lock-ops.mjs` | Compliant | Used for lock events (Kind 30078 is used, which is Application Specific Data, functionally similar to replaceable events). |
+
+## Libraries
+
+| Library | Version | Usage | Risks |
+| :--- | :--- | :--- | :--- |
+| `nostr-tools` | `2.19.4` | Core Nostr primitives (keys, events, pool). | Supply chain risk. pinned version recommended. |
+| `ws` | `8.19.0` | WebSocket client for Node.js. | standard library for Node.js websocket support. |
+
+## Implementation details
+
+- **Locking Mechanism**: Uses Kind 30078 (Application Specific Data) for lock events.
+- **Relay Communication**: Uses `SimplePool` from `nostr-tools` for querying and publishing.
+- **Health Checks**: Uses raw `WebSocket` connections in `src/relay-health.mjs` for deep health probes.

+# Protocol Report - 2026-02-15
+
+## Summary
+
+This report analyzes the usage of external protocols (primarily Nostr) and related libraries in the `torch-lock` repository.
+
+## Findings
+
+1.  **Nostr Implementation**:
+    - The repository relies heavily on `nostr-tools` for interacting with Nostr relays.
+    - It uses Kind 30078 for lock events, which is appropriate for application-specific data.
+    - `SimplePool` is used for managing relay connections and subscriptions.
+
+2.  **Dependencies**:
+    - `nostr-tools`: v2.19.4. This is a recent version (v2+).
+    - `ws`: v8.19.0. Standard WebSocket implementation for Node.js.
+
+3.  **Compliance**:
+    - The implementation appears compliant with NIP-01 (Events, signatures, subscriptions).
+    - The use of `tags` for filtering locks (`d` tag, `t` tags) aligns with Nostr best practices for parameterized replaceable events (though Kind 30078 is used).
+
+4.  **Risks**:
+    - **Relay Availability**: The system is dependent on the availability of configured relays. `src/relay-health.mjs` provides mitigation by probing health.
+    - **Race Conditions**: The locking mechanism relies on relay propagation and a race check delay (`RACE_CHECK_DELAY_MS`).
+
+## Recommendations
+
+1.  **Monitor `nostr-tools` updates**: Keep the library updated to receive security patches.
+2.  **Enhance Relay Health Checks**: Continue to refine `src/relay-health.mjs` to handle edge cases (e.g., slow relays, auth requirements).
+3.  **Formalize NIP Support**: Explicitly document which NIPs are supported/required in `PROTOCOL_INVENTORY.md`.
+
+## Artifacts Created
+
+- `PROTOCOL_INVENTORY.md`: Initial inventory of protocols.

+# Context Note (2026-02-15) - Protocol Research Agent
+
+- **agent**: protocol-research-agent
+- **cadence**: daily
+- **run-start**: 2026-02-15T00:00:00Z
+- **prompt**: src/prompts/daily/protocol-research-agent.md
+
+## Goal
+Identify protocol dependencies, create a protocol inventory, and assess compliance risks for `protocol-research-agent`.
+
+## Scope
+- `torch-lock` repository.
+- `nostr-tools` and `ws` usage.
+- Nostr protocol compliance.
+
+## Constraints
+- Do not modify core logic unless critical.
+- Focus on documentation and analysis.
+
+## Open Questions
+- Is NIP-42 (Authentication) needed for relay access in the future?

+- **prompt**: src/prompts/daily/protocol-research-agent.md
+
+## Decision: Create `PROTOCOL_INVENTORY.md`
+- **Rationale**: To centralize knowledge about external protocols and ensure compliance.
+- **Alternatives Considered**: Add to `README.md` (too cluttered).
+- **Consequences**: Future agents should update this file when adding/changing protocol usage.
