### Enforcement Rules

1. **No new TypeScript or AffineScript files** - Use AffineScript; meaningfully migrate existing TS/JS to AffineScript when touched (per-language `examples/` references may stay)
2. **No package.json for runtime deps** - Use deno.json imports
3. **No node_modules in production** - Deno caches deps automatically

2. **Use `package.json` + `bun.lock` for JS runtime deps** - Bun is npm-compatible; a manifest is REQUIRED

🌐 Web query:

site:bun.sh/docs/pm/lockfile bun.lockb bun.lock 1.2

💡 Result:

In Bun 1.2, the default lockfile format was changed to a human-readable, text-based file named bun.lock, replacing the previous binary format, bun.lockb [1]. To migrate from an existing bun.lockb file to the new bun.lock format, you should run the following command [1]: bun install --save-text-lockfile --frozen-lockfile --lockfile-only After running this command, you can safely delete the legacy bun.lockb file [1]. When you run bun install in a project, Bun will automatically generate the bun.lock file if it is not already present [1].

Define the minimum supported Bun version.

mise.toml selects bun = "latest" but does not define a minimum version. If Bun versions before 1.2 remain supported, document the minimum version and the bun.lockb migration rule.

In @.claude/CLAUDE.md at line 66, Update the Bun dependency guidance in
CLAUDE.md to document the minimum supported Bun version, and specify the
bun.lockb migration rule if versions before 1.2 remain supported. Align the
documentation with the bun version selected by mise.toml and the existing
package.json/bun.lock requirements.

3. **`bun install --production` for production deps** - resolved from `package.json`, pinned via `bun.lock`
4. **No Go code** - Use Rust instead
5. **No Python anywhere** - Use Julia for data/batch, Rust for systems, AffineScript for apps
6. **No Kotlin/Swift for mobile** - Use Tauri 2.0+ or Dioxus

- **JS deps**: Deno (deno.json imports)
- **JS deps**: Bun (`package.json` + `bun.lock`). Declare tooling as a devDependency and run `bunx --no-install --bun <tool>` — a bare `bunx <tool>` can fetch an unpinned package and may start Node via its shebang.
