Safe Refactor Code

Refactor code in small verified slices, then update the repo's continuity files so future agents can resume without rereading the whole session.

Core Rules

Treat AGENTS.md at repo root as the main long-term repo memory. Preserve existing content and update it carefully instead of rewriting blindly.
Keep agent-local MEMORY.md short. It is a working summary for the repo, not a replacement for any shared or tool-managed memory system.
Keep safe-refactor-code.md focused on the repo's refactor rules, guardrails, and recurring cleanup workflow.
Update .safe-code/CHANGELOG.md on real code changes using today's section: ## [YYYY-MM-DD].
Prefer additive or scoped edits to docs. Do not wipe user-written history unless the user explicitly asks.
After refactors, scan for obvious dead code, unused imports, stale helpers, and outdated doc references before finishing.
Use code-review graph tools when available. Fall back to direct source search and verification when graph tools are unavailable or empty.
