+# Dependency Security Report
+
+**Date:** 2026-02-20
+**Run ID:** 2026-02-20T01-13-24Z
+**Agent:** deps-security-agent
+
+## Summary
+- **Vulnerabilities:** 5 (1 High, 4 Moderate)
+- **Outdated Packages:** 0
+
+## Vulnerabilities
+
+### High Severity
+- **minimatch** (<10.2.1)
+  - **Path:** eslint > minimatch
+  - **Issue:** ReDoS via repeated wildcards.
+  - **Status:** Transitive dependency of `eslint@10.0.0`.
+
+### Moderate Severity
+- **ajv** (<8.18.0)
+  - **Path:** eslint > ajv
+  - **Issue:** ReDoS when using `$data` option.
+- **eslint**, **@eslint/js**, **@eslint-community/eslint-utils**
+  - **Issue:** Various moderate issues related to internal dependencies.
+
+## Outdated Packages
+- None (all dependencies up to date with package.json specifiers).
+
+## Recommendations
+- Monitor `eslint` for updates that bump `minimatch` and `ajv`.
+- Consider using `overrides` in package.json to force `minimatch@10.2.1` if `eslint` is compatible.

+# Context: Decompose src/lock-ops.mjs
+
+## File Selection
+- **File:** `src/lock-ops.mjs`
+- **Size:** 881 lines (Excess: 581 lines)
+- **Selection Reason:** Single largest grandfathered source file available for decomposition.
+- **Recent History:** Last significant commit was a merge (`e1052814`). No recent decomposition or major refactor found in `git log`.
+
+## Decomposition Plan
+The file contains three major cohesive blocks:
+1. **RelayHealthManager**: A class for tracking relay health, scoring, and metrics.
+2. **LockPublisher**: A class for publishing lock events with retries and fallback logic.
+3. **Lock Operations**: The core `queryLocks` and `parseLockEvent` logic.
+
+### Extraction Strategy
+1. **Extract `RelayHealthManager`** into `src/relay-health-manager.mjs`.
+   - Includes: `RelayHealthManager` class, `defaultHealthManager` instance, `summarizeRelayMetrics`, `computeRelayScore`, `buildRelayHealthConfig`.
+   - Exports: `RelayHealthManager`, `defaultHealthManager`, `buildRelayHealthConfig`.
+
+2. **Extract `LockPublisher`** into `src/lock-publisher.mjs`.
+   - Includes: `LockPublisher` class, `publishLock`, `publishToRelays`.
+   - Includes: `classifyPublishError` and related constants (`PUBLISH_ERROR_CODES`, `PUBLISH_FAILURE_CATEGORIES`).
+   - Includes: `secureRandom`, `calculateBackoffDelayMs`.
+   - Internal Helpers (duplicated): `withTimeout`, `relayListLabel`.
+   - Exports: `publishLock`, `LockPublisher`.
+
+3. **Refactor `src/lock-ops.mjs`**.
+   - Import `defaultHealthManager`, `buildRelayHealthConfig`, `publishLock`.
+   - Remove extracted code.
+   - Retain `queryLocks`, `parseLockEvent`, `filterActiveLocks`.
+   - Retain `withTimeout` and `relayListLabel` (for local use).
+
+## Goal
+Reduce `src/lock-ops.mjs` by > 200 lines.

+# Decisions: Decompose src/lock-ops.mjs
+
+## Decision 1: Extract `RelayHealthManager`
+- **Rationale:** The `RelayHealthManager` class manages complex state and logic for relay health metrics, scoring, and prioritization. It is a distinct cohesive block that can be reused and tested independently.
+- **Target File:** `src/relay-health-manager.mjs`.
+
+## Decision 2: Extract `LockPublisher`
+- **Rationale:** The `LockPublisher` class encapsulates the retry logic, backoff strategy, and publishing workflow. Separating it clarifies the distinction between "publishing a lock" and "managing locks generally".
+- **Target File:** `src/lock-publisher.mjs`.
+
+## Decision 3: Move utilities
+- **Rationale:** Utilities like `withTimeout` and `mergeRelayList` are used by both the extraction targets and the original file. Moving them to `src/lock-utils.mjs` (or similar) avoids circular dependencies.
+
+## Decision 4: Skip baseline update in script
+- **Rationale:** The `scripts/check-file-size.mjs` script does not support `--update` or maintain a `BASELINE` constant as described in the prompt. I manually verified that `src/lock-ops.mjs` is now under the limit (152 lines).

+- **Rationale**: The audit of `docs/` revealed that the directory currently houses internal documentation (`agent-handoffs`, `architecture`, `proposals`, etc.) rather than user-facing guides about file uploads or contributions.
+- **Action**: Created inventory artifact documenting the state of `docs/` but did not modify any files.

+Prompt: src/prompts/daily/deps-security-agent.md
+
+## Decision: Defer Upgrades
+- **Rationale:** The identified High severity vulnerability (`minimatch`) is a transitive dependency of `eslint`. Automatic upgrading of transitive dependencies is disabled to prevent instability. `npm outdated` shows `eslint` is up to date with the registry for the specified range.
+- **Action:** Logged as pending task for manual review or future automated check when `eslint` updates.
+
+## Decision: No Safe Upgrades Available
+- **Rationale:** `npm outdated` returned no results, indicating all direct dependencies are at their latest satisfying versions.

+# Decisions: Decompose src/lock-ops.mjs
+
+## 1. Duplicate Internal Helpers (`withTimeout`, `relayListLabel`)
+- **Context:** Both `src/lock-ops.mjs` and the new `src/lock-publisher.mjs` need `withTimeout` and `relayListLabel`.
+- **Option A:** Move them to `src/utils.mjs`.
+- **Option B:** Duplicate them in the new file.
+- **Decision:** **Option B (Duplicate)**.
+- **Rationale:** The prompt emphasizes "One file per PR only" and "Do not decompose multiple files". Modifying `src/utils.mjs` would touch a second existing file, potentially expanding the scope and risk. Duplicating these small helpers keeps the changes isolated to the decomposition of `src/lock-ops.mjs` and its new children.
+
+## 2. Shared Constants
+- **Context:** Extracted files need constants from `src/constants.mjs` and `src/torch-config.mjs`.
+- **Decision:** Import them directly in the new files.
+- **Rationale:** Standard module practice.
+
+## 3. Class Extraction
+- **Context:** `RelayHealthManager` and `LockPublisher` are large, distinct classes.
+- **Decision:** Extract each into its own file (`src/relay-health-manager.mjs`, `src/lock-publisher.mjs`).
+- **Rationale:** Improves modularity and reduces the size of `src/lock-ops.mjs` significantly.

+# Test Log: Decompose src/lock-ops.mjs
+
+## Date
+2026-02-20
+
+## Verification Steps
+
+1. **Linting**
+   - Command: `npm run lint`
+   - Result: Passed (after fixing unused `relayListLabel` in `src/lock-publisher.mjs`).
+
+2. **Unit Tests**
+   - Command: `npm test`
+   - Result: Passed (294 tests).
+   - Key Tests Covered:
+     - `test/lock-ops.test.mjs` (implicitly covered by keeping API compatible and general suite passing).
+     - `test/run-scheduler-cycle.mjs` (integration).
+
+3. **File Size Check**
+   - Command: `node scripts/check-file-size.mjs --report`
+   - Result: `src/lock-ops.mjs` is no longer in the report (meaning it is < 300 lines).
+   - Previous Size: 881 lines.
+   - New Size: < 300 lines.
+   - Reduction: > 581 lines.
+
+## Artifact Verification
+- `src/relay-health-manager.mjs` created and verified.
+- `src/lock-publisher.mjs` created and verified.
+- `src/lock-ops.mjs` refactored and verified.
