Maintainability · Low — Redundant recomputation of persona collector pack can cause divergence and unnecessary work
src/agent/agent-runner.js

collectorPack is computed in runSyntheticUserAgentTurn and then recomputed inside composeArtifact with similar inputs. This duplication risks divergence if either call drifts and adds avoidable CPU cost.

Fix: Compute collectorPack once in the caller and pass it as a parameter to composeArtifact. Remove the internal recomputation to keep a single source of truth.

Out-of-hunk patch artifact (model: claude-opus-4-7)

This non-click-to-apply fix is outside the PR diff hunk, so GitHub cannot render it as a suggestion.
