## Fast Path
20
20
21
+
- Start here for most changes: `maid preflight`
21
22
- Build from an existing configured tree: `meson compile -C build`
22
23
- Fresh local setup: `maid setup`
23
24
- Run a focused test file: `./build/ant tests/test_<name>.cjs`
24
25
- Run the spec suite: `./build/ant examples/spec/run.js`
25
-
- Validate repo knowledge docs: `maid knowledge`
26
-
- Validate changed-file boundaries: `maid structure`
27
-
- Route the current diff to the right checks: `maid validate_changes`
26
+
- Run the individual harness steps when needed:
27
+
`maid validate_changes`, `maid structure`, `maid knowledge`

## Change Rules

50
50
- Prefer changes in `src/`, `include/`, `meson/`, `tests/`, `tools/`, and `.github/agents/`.
51
-
- Treat `vendor/`, `build/ as generated or third-party surfaces.
52
-
Only edit them when the task explicitly requires it.
51
+
- Treat `vendor/` and `build/` as generated or third-party surfaces. Only edit
52
+
them when the task explicitly requires it.
53
53
- Keep durable design notes and execution history in versioned markdown under
54
54
`docs/`. Treat `todo/` as scratch space, not the source of truth.
55
55
- Add or update tests when behavior changes.
56
56
- When touching build or runtime invariants, document the reasoning in
57
57
[docs/exec-plans/index.md](docs/exec-plans/index.md) or a linked plan if the
58
58
work spans multiple steps.
59
+
- Before finalizing most code changes, run `maid preflight` and then execute any
60
+
additional build or spec commands it recommends, or explain why they were not
61
+
run.
