policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #59
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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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
This PR transitions the repository's AI policy to establish Bun as the Tier 1 JS/TS runtime, replacing Deno and mandating package.json and bun.lock for dependency management. While the primary runtime transition is defined, the implementation fails to address several 'blanking scar' repairs mentioned in the PR description, specifically regarding the restoration of ReScript-related rules. Additionally, the recommended production installation command lacks necessary flags to ensure lockfile integrity.
About this PR
- Several 'blanking scar' repairs mentioned in the PR description—such as restoring 'ReScript' and 'AffineScript' text—are missing from the actual code changes. Furthermore, there appears to be a mismatch between the provided diff baseline and the 'corrupted' state described, which may indicate that the PR is based on an incorrect branch or version of the file.
Test suggestions
- Verify that an AI agent reading the policy identifies Bun as the primary runtime and package manager\n- [ ] Verify that the policy mandates the presence of package.json and bun.lock files for JS dependencies\n- [ ] Verify that Deno is no longer listed as an allowed runtime or package manager
Prompt proposal for missing tests

Restore the missing ReScript policy text.
The PR objective states that this change restores both ReScript and AffineScript, but the supplied policy content contains AffineScript only. Add the intended ReScript entry, or update the objective if its omission is deliberate.

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.
