policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #71
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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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.

Pull Request Overview
The PR successfully transitions the project to Bun as the Tier 1 runtime and package manager. However, the implementation is incomplete regarding the stated intent to repair 'ReScript purge' text in the enforcement rules and banned tables. There is also a risk of confusion where Bun's native TypeScript support is highlighted, as this contradicts the project's 'No new TypeScript files' policy. Additionally, while Deno is being replaced, it has not been explicitly added to the banned tools list to prevent AI assistant regression. Codacy analysis indicates the changes are otherwise up to standards.
About this PR
- Scope misalignment: The PR description explicitly claims to fix 'blanking scars from the ReScript purge' by restoring the word 'ReScript' in several locations (such as Enforcement Rule #1 and the Banned table), but the diff does not contain these changes.
Test suggestions
- Verify Bun is listed as Tier 1 default for new work in the ALLOWED table
- Verify Node.js/npm/pnpm/yarn are mapped to Bun in the BANNED table
- Verify the explicit requirement for
package.jsonandbun.lockmanifests - Verify 'ReScript' is restored to the BANNED table as claimed in the description
- Verify Enforcement Rule #1 is updated to mention 'ReScript' and '.res' files
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify 'ReScript' is restored to the BANNED table as claimed in the description
2. Verify Enforcement Rule #1 is updated to mention 'ReScript' and '.res' files
Low confidence findings
- The description claims to fix line 20 ('Only where cannot' -> 'Only where AffineScript cannot'), but the existing code already contained 'AffineScript'.

Suggestion: Deno is being removed as a Tier 1 tool but hasn't been added to the Banned table. Adding it ensures the AI assistant avoids using it in favor of Bun.

⚪ LOW RISK
Nitpick: This note conflicts with the project's 'No new TypeScript files' policy (Rule 1). Since the codebase must use AffineScript or JavaScript, Bun's native TypeScript support should not be highlighted as a feature to avoid confusion.

Synchronise all repository policy sources before adopting Bun.
.github/REPO_CONFIG.md still maps Node.js and npm/bun to Deno. Mustfile.epx still lists Bun in banned.runtimes. Consumers of these files can select Deno or reject Bun while this file declares Bun as tier 1. Update these contracts, or define .claude/CLAUDE.md as the authoritative source and remove the conflicting entries before merging.

Update lockfile validation to use bun.lock.
If JavaScript runtime dependencies exist, validate-no-npm does not reject a missing bun.lock. validate-policy includes this recipe, but no other validator enforces the required lockfile. Update the recipe to check bun.lock, or add an active validator for this contract.

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).

All substantive review findings are addressed in the latest push.
Declined, with reasons: "a npm-compatible" — LanguageTool is wrong; "an" is correct before a vowel sound. " Dismissing the stale review on that basis; the original review, this reply, and the dismissal reason all remain on the PR. |
Addressed in the latest push; the preceding comment lists what was fixed and what was declined with reasons. Owner ruled TypeScript should not exist at all, so every .ts reference is gone from the Bun row; Deno added to BANNED; bunx now requires a declared devDependency plus --no-install --bun; description regenerated from the diff.
