# Code Review — TP-087 Step 1: Design the enum and aliases

## Verdict: APPROVE

No blocking code-review findings for Step 1.

The reviewed diff only adds the Step 1 design record in `STATUS.md` plus prior review notes; no Go implementation files are changed yet. The current design record is consistent enough to guide Step 2: it defines the closed scalar metric inventory, canonical/alias policy, expression rejection rules, hint categories, source metadata shape, and schema/docs implications.

## Notes

- I reviewed the committed diff from `15c001e..HEAD` and read the current `STATUS.md`/task prompt for context.
- No tests were run because this step contains planning/documentation changes only.
- Implementation should follow the existing non-blocking guardrails already captured in R005: schema enums must remain canonical-only, aliases should be tested deliberately, and analyzer routing should not be overbuilt in this task.
