-# Context: 2026-02-14 Constants Refactor
+# Context: Decompose src/lib.mjs
+
+## Chosen File
+`src/lib.mjs` (approx 700 lines).
+
+## Reason for Selection
+It is one of the largest grandfathered files (excluding HTML files which are harder to module-decompose). It contains mixed concerns: roster management, lock operations, and dashboard server logic.
+
+## Extraction Plan
+1. Extract roster logic to `src/roster.mjs`.
+2. Extract lock operations to `src/lock-ops.mjs`.
+3. Extract dashboard logic to `src/dashboard.mjs`.
+4. Move configuration helpers to `src/torch-config.mjs` and constants to `src/constants.mjs`.
 
 ## Goal
-To refactor duplicate or magic numeric literals into a canonical constants file.
-Specifically targeting `4173` (default dashboard port) and `1500` (race check delay).
-
-## Scope
-- Create `src/constants.mjs`.
-- Modify `src/lib.mjs`.
-
-## Constraints
-- Must preserve existing values.
-- Must pass lint and tests.
-- Must follow `const-refactor-agent` guidelines.
+Reduce `src/lib.mjs` by at least 200 lines while preserving behavior.
