Design & Implementation Notes + +- **Entry point / key function**: `ensureSessionInitialized()` in `state.ts` handles migration when loading persisted state +- **Key configuration items**: Ref format `%05d` (5-digit zero-padded) +- **Key logic explanation**: Migration iterates `byRef` map, identifies 4-digit keys matching pattern `m\d{4}`, and re-inserts with 5-digit format.

Lessons Learned + +- What went well: Dual-agent review caught the `byRef` normalization bug that self-review missed +- What could be improved: Should have tested migration with actual persisted state from a real session +- Reusable conclusions: Format changes in persisted data always need migration logic, not just format updates. The `byRef` map is a particularly tricky case because keys and values both contain refs. diff --git a/devlog/DESIGN.template.md b/devlog/DESIGN.template.md new file mode 100644 index 0000000..be72502 --- /dev/null +++ b/devlog/DESIGN.template.md @@ -0,0 +1,54 @@ +# DESIGN - + +- Task ID: `<YYYY-MM-DD_short-title>` +- Home Repo: `opencode-acp` +- Created: <YYYY-MM-DD> +- Status: Draft | Accepted | Superseded + +## 1.
