⚪ LOW RISK

The acceptance criteria specify restoring the 'ReScript' terminology here to fix corruption from a previous purge. This line currently contains a blank space where the keyword was intended to be restored.

🟡 MEDIUM RISK

The policy change removes Deno as a Tier 1 tool, but it is missing from the BANNED table. To align with the goal of removing Deno and ensuring AI assistants avoid its use, it should be explicitly listed as banned for new code (e.g., mapping to Bun). Additionally, the runtime compatibility list at line 139 (marked 'Deno ✅') needs reconciliation with this removal.

Suggested change for the BANNED table:

🟡 MEDIUM RISK

Suggestion: To complete the removal of Deno as a primary tool and provide clear guidance for the AI agent, add Deno to the BANNED table with Bun as the recommended replacement, mirroring the existing entries for Node.js and npm.

### Enforcement Rules

1. **No new TypeScript files** - Write new code in AffineScript (closed exemptions table below covers the residual `.d.ts` / Deno-test cases).
2. **No new files** - As of 2026-05-25 policy refresh; AffineScript is the go-forward. Existing `.res` files stay until migrated via #488.
3. **No package.json for runtime deps** - Use deno.json imports.
4. **No node_modules in production** - Deno caches deps automatically.
2. **No new ReScript files** - As of 2026-05-25 policy refresh; AffineScript is the go-forward. Existing `.res` files stay until migrated via #488.

🟡 MEDIUM RISK

The reference in Rule 1 (line 103) is incorrect. The mentioned exemptions (.d.ts and Deno-test) are in the Approved table at line 116, not the Closed table. Correcting this reference is critical for the AI agent to properly distinguish between active exemptions and resolved legacy items.

3. **Use `package.json` + `bun.lock` for JS runtime deps** - Bun is npm-compatible; a manifest is REQUIRED
4. **`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
5. **No Go code** - Use Rust instead.
6. **Python only for SaltStack** - All other Python must be rewritten.
7. **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.
