# Retro: #60 — Investigate bumping tsconfig target/lib to ES2023+

## Final Retrospective (2026-05-04T22:16:00-04:00)

### Session summary

Clean execution across plan → build → ship.
Bumped `tsconfig.json` target to ES2023, updated `AGENTS.md` constraints, and refactored `evaluate()` and `findCompiledWildcardMatch()` to use `findLast`.
Released as v4.6.0 with no rework or corrections needed.

### Observations

#### What went well

- Three-step plan mapped 1:1 to three clean commits with no deviations.
- Existing 49 tests in the affected files (and full suite of 890) served as a reliable refactor harness — no new tests needed.
- Biome pre-commit hook caught autoformat needs transparently; no manual intervention required.

#### What caused friction (agent side)

- None identified.

#### What caused friction (user side)

- None identified.
