policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #116
Conversation
Owner ruling 2026-08-26: "deno is to go and bun is the way we are going, put it
first everywhere unless not possible and explain why if not".
This file is what an agent reads FIRST and it listed Bun as BANNED with Deno as
its replacement. Correcting hyperpolymath/standards (#655) fixes one copy of
~372 - agents read the local one. This is that local copy.
ALLOWED **Deno** "Replaces Node/npm/bun" -> **Bun** tier 1
BANNED | Bun | Deno | -> row REMOVED
BANNED Node.js / npm / pnpm/yarn -> Deno -> -> Bun
rule "No package.json for runtime deps - use deno.json imports"
-> Use package.json + bun.lock; a manifest is REQUIRED
rule "No node_modules in production"
-> bun install --production, pinned via bun.lock
pkg JS deps: Deno -> JS deps: Bun (package.json + bun.lock), bunx
WHY THE MANIFEST RULE MATTERS MOST. "No package.json for runtime deps" did not
express a preference - it told repos not to declare their dependencies at all.
hyperpolymath/ubicity imported zod and glob, shipped NO manifest of any kind,
and could not build under ANY toolchain. Fixed in ubicity#107; the rule that
caused it is fixed here.
ALSO REPAIRED - blanking scars from the ReScript purge, which substituted the
token with an EMPTY STRING rather than removing the text:
| | AffineScript | -> | ReScript | AffineScript |
1. **No new files** ... -> **No new ReScript files** ...
| **JavaScript** | Only where cannot | -> Only where AffineScript cannot
Restoring the NAME in a policy table does not reintroduce the language. Same
root cause as the rm -rf /lib found in wordpress-tools#62.
Policy text only - no code, no workflows, no build files. 1 file(s).
NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per
ADR-2026-STACK-MIGRATION) but that is a separate ruling; flagged, not changed.

Estimated code review effort: 1 (Trivial) | ~3 minutes Merge Risk: 🟡 Moderate · up to This PR changes the repository’s runtime policy to require Bun and remove Deno, but the existing runtime audit path still checks the old lockfile and recommends Deno. That mismatch can produce false compliance results and conflicting developer guidance, so it should be resolved or explicitly accepted before merge. Poem

Pull Request Overview
The PR successfully initiates the transition to Bun as the Tier 1 runtime; however, it is not currently up to the standards promised in the description. Codacy analysis indicates the file structure is technically sound, but the implementation lacks critical elements mentioned in the intent.
Two major issues prevent merging: first, the 'blanking scars' from the ReScript purge remain unaddressed despite the PR description claiming to repair them. Second, there is a direct contradiction between the instructions for Bun (which mention executing .ts files) and Enforcement Rule 1 (which bans new TypeScript files). These contradictions will likely confuse AI agents. Finally, Deno should be explicitly added to the Banned table to maintain consistency with how the repository handles replaced technologies.
About this PR
- The PR description claims to repair 'blanking scars from the ReScript purge' and update Rule 1 to 'No new ReScript files', yet the provided diff shows no changes to these areas. Rule 1 still reads 'No new TypeScript files' and table labels remain empty or unchanged. Please verify if these changes were omitted from the commit.
Test suggestions
- Verify the CLAUDE.md policy file correctly reflects Bun as the default runtime and package manager.
- Verify that the Banned tools table lists Node.js/npm/pnpm/yarn/Deno as replaced by Bun.
- Validate that ReScript labels have been restored in the Banned table and Enforcement Rules.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify the CLAUDE.md policy file correctly reflects Bun as the default runtime and package manager.
2. Verify that the Banned tools table lists Node.js/npm/pnpm/yarn/Deno as replaced by Bun.
3. Validate that ReScript labels have been restored in the Banned table and Enforcement Rules.

🟡 MEDIUM RISK
Deno is missing from the Banned table despite the PR's objective to remove it. Explicitly banning it ensures AI assistants follow the transition to Bun and do not attempt to use Deno as a fallback.

⚪ LOW RISK
Suggestion: The mention of Bun executing .ts directly contradicts the project's 'No new TypeScript files' rule. Reframing the description around ESM performance provides clearer guidance for AI agents. Additionally, explicitly noting the preference for the text-based bun.lock format (readable by LLMs) over the binary default bun.lockb is beneficial.
| | **Bun** | JS/TS runtime & package management (tier 1) | Default for all new work. Executes `.ts` directly, no build step. Uses an npm-compatible `package.json` plus `bun.lock` — both are expected, not anti-patterns. | | |
| **Bun** | JS/TS runtime & package management (tier 1) | Default for all new work. High-performance JS/ESM runtime. Uses an npm-compatible `package.json` plus `bun.lock` (text format) — both are expected. | |
Review feedback from codacy-production and coderabbitai on the policy wave. Three substantive points, all accepted: 1. ".ts CONTRADICTION" (codacy, MEDIUM, raised on most of the wave). The Bun row said "Executes .ts directly, no build step" in a file whose BANNED table bans TypeScript. OWNER RULING: TypeScript "should not exist at all", so advertising Bun's TypeScript capability is wrong regardless of whether it is true. Every .ts reference is removed from the row, including "JS/TS" in its label. 2. "DENO MISSING FROM BANNED" (codacy, raised repeatedly). The wave removed Deno from ALLOWED but never added it to BANNED, so the ruling was only half expressed. Added | Deno | Bun |. 3. "UNPINNED bunx" (coderabbitai, Security & Privacy). A bare `bunx <tool>` can fetch a package outside package.json/bun.lock, and can start Node via a shebang - both contrary to estate SHA-pinning doctrine and the Node ban. Guidance now requires a declared devDependency plus `bunx --no-install --bun <tool>`. NOT taken: "a npm-compatible" (LanguageTool is wrong, "an" is correct before a vowel sound); "--frozen-lockfile is redundant" (correct - no change needed, and none made); the Nix->Guix point (real, but a separate ruling, deliberately not folded into a Deno/Bun change).
Addresses the two live static-analysis findings on this PR. ReScript was absent from the BANNED table although canon bans it (destination AffineScript), so the table read as permitting it. Enforcement Rule 3 said `bun install --production` with no `--frozen-lockfile`, so a lockfile mismatch silently re-resolved instead of failing, which defeats the point of committing `bun.lock`. Enforcement Rule 1 is deliberately untouched: standards#655 records that collision as not resolvable unilaterally. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Synchronise the runtime auditor with the Bun policy.
repo_auditor.exs:17 invokes detect_runtime_violations/1 during run/2. The function checks only bun.lockb, so a repository with the required package.json and bun.lock receives no runtime finding. It also recommends Deno, which conflicts with the Bun-first policy. Update the auditor and add tests for the Bun contract.
