🟡 MEDIUM RISK

The language policy is now inconsistent. While this line and line 49 use 'AffineScript', the primary language table (line 9), the TypeScript/Python replacement rules (lines 27, 32), and the mobile enforcement rule (line 53) still use 'ReScript'. These should be unified to ensure the AI follows a single consistent language standard.

Align the Bun policy with repository automation.

The new policy bans npm and requires package.json plus bun.lock, but .github/workflows/ci.yml Lines 59-87 still provisions Node.js, caches frontend/package-lock.json, and runs npm ci. A dependency change that follows this policy can therefore use a lockfile that CI does not validate. Update the workflow to use Bun, or scope this policy to workspaces that have migrated.

Also applies to: 49-51, 60-60

In @.claude/CLAUDE.md around lines 28 - 30, Align the repository’s CI workflow
with the Bun policy by replacing Node.js/npm provisioning, package-lock caching,
and npm ci installation with Bun setup, bun.lock caching, and Bun dependency
installation; otherwise narrow the policy to only migrated workspaces.

### Enforcement Rules

1. **No new TypeScript files** - Convert existing TS to ReScript
2. **No package.json for runtime deps** - Use deno.json imports
3. **No node_modules in production** - Deno caches deps automatically

🟡 MEDIUM RISK

Inconsistency: This rule introduces 'AffineScript' as the target for TypeScript conversion, but the primary language entry (line 9) and rule 5 (line 53) still use 'ReScript'. All references should be synchronized to prevent agent confusion.

2. **Use `package.json` + `bun.lock` for JS runtime deps** - Bun is npm-compatible; a manifest is REQUIRED
3. **`bun install --production --frozen-lockfile` for production deps** - resolved from `package.json` and pinned via `bun.lock`; `--frozen-lockfile` makes a lockfile mismatch a build failure rather than a silent re-resolve
4. **No Go code** - Use Rust instead
5. **No Python anywhere** - Use Julia for data/batch, Rust for systems, ReScript for apps
6. **No Kotlin/Swift for mobile** - Use Tauri 2.0+ or Dioxus

- **Primary**: Guix (guix.scm)

- **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.
