policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #140
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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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 change makes Bun the local default, but other repository guidance still bans Bun and requires Deno while an existing script still uses Deno, leaving contradictory instructions that could cause incompatible runtime choices.

Pull Request Overview
While the core transition from Deno to Bun as a Tier 1 runtime is correctly implemented, there is a significant discrepancy between the PR description and the actual changes. Specifically, the promised restoration of ReScript terminology and the correction of enforcement rules are missing from the diff. Additionally, the description of Bun as executing .ts directly introduces a contradiction with the repository's strict "No new TypeScript" policy. High-severity issues regarding PII in the copyright header and a broken documentation link must be addressed before merging.
About this PR
- The PR description details a 'repair' of ReScript-related policy text and enforcement rules, but these changes are entirely absent from the diff. Specifically, the restoration of ReScript to the banned table and the update to Rule 1 for .res files are missing.

Test suggestions
- Verify Bun is listed as Tier 1 in the ALLOWED table.
- Verify Deno references are replaced with Bun in the BANNED table and notes.
- Verify the enforcement rule for mandatory package.json and bun.lock is present.
- Missing ReScript terminology restoration in the BANNED table (e.g. '| ReScript | AffineScript |').
- Missing Enforcement Rule 1 update to reference ReScript (.res) files instead of TypeScript.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Missing ReScript terminology restoration in the BANNED table (e.g. '| ReScript | AffineScript |').
2. Missing Enforcement Rule 1 update to reference ReScript (.res) files instead of TypeScript.
Low confidence findings
- The description claims to fix a corruption where 'Only where cannot' was changed to 'Only where AffineScript cannot', but the diff shows the previous version already contained the correct full text.

🟡 MEDIUM RISK
The note 'Executes .ts directly, no build step' contradicts the project's 'No new TypeScript' rule and the requirement to use AffineScript. To prevent the AI from incorrectly defaulting to TypeScript, this phrase should be removed.

--productionmode already implies--frozen-lockfile, so this command uses the committed lockfile resolution and rejects manifest drift.
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.
