+## Standard library modules

+The toolchain ships a small stdlib in `lib/`, imported by name like in V

+Module functions are namespaced: `os.exists()`, `json.encode()`, ...

+| --- | --- |
+| `os` | filesystem + process: `exists`, `is_dir`, `is_file`, `mkdir`, `remove`, `copy`, `list_dir`, `glob`, `join`, `base`, `dir`, `read_lines`, `write_lines`, `cwd`, `env`, `exec` |
+| `json` | `encode`, `decode`, `pretty` — objects become structs, integral numbers decode as ints, `null` ⇄ `none` |
+| `strings` | `length`, `lines`, `split`, `join`, `replace`, `contains`, `starts_with`, `ends_with`, `upper`, `lower`, `trim`, `pad`, `pad_left`, `repeat`, `format`, `capitalize` |
+| `math` | `abs`, `min`, `max`, `floor`, `ceil`, `round`, `sqrt`, `pow`, `clamp`, `sign`, `pi` |
+| `http` | `get(url)`, `post(url, data)`, `get_text(url)` — return `{status, body}`; network failures throw (catchable), HTTP errors (404) are normal responses |
+| `time` | `now()` (epoch s), `ms()` (epoch ms), `format(t, "YYYY-MM-DD HH:mm:ss")`, `date(t)`, `clock(t)`, `parse("2026-08-25 13:36:45")` — Moment-style tokens |
