policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #69
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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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.

📝 WalkthroughSummary by CodeRabbit
WalkthroughThe project guidance replaces Deno with Bun as the default JavaScript and TypeScript runtime. It updates allowed and banned language rules, manifest requirements, production installation commands, dependency management, and one-off tooling guidance. ChangesBun policy migration
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to The policy now directs users and agents toward Bun, but it conflicts with the documented healing setup, permits one-off tooling that may not be reproducible, and is ambiguous about TypeScript usage. These issues could leave contributors with an unsupported or inconsistent setup, so follow-up is needed before merge. Poem

Pull Request Overview
This PR promotes Bun to a Tier 1 runtime and establishes mandatory usage of package.json and bun.lock. While the technical migration to Bun is largely present, the PR fails to deliver on the 'blanking scars' repair mentioned in the description; the restoration of ReScript terminology in the policy tables and enforcement rules is missing.
Furthermore, the policy for Bun mentions direct execution of .ts files, which contradicts the project's strict prohibition of TypeScript in favor of AffineScript. There is also a consistency gap where Deno, though being removed, has not been explicitly added to the banned tools list as intended.
About this PR
- The PR description mentions repairing 'blanking scars' from the ReScript purge (restoring the ReScript name in policy tables and rule #1), but these changes are not present in the provided files. Please ensure the 'Also repaired' section of the PR intent is actually reflected in the code.
Test suggestions
- Verify Bun is listed in the ALLOWED table with Tier 1 status and package management details
- Verify Deno is replaced by Bun in the BANNED table for Node.js, npm, and pnpm/yarn
- Verify enforcement rule 2 requires package.json and bun.lock
- Verify enforcement rule 3 specifies bun install --production
- Verify 'ReScript' terminology is restored in the BANNED table and Enforcement Rule 1

🟡 MEDIUM RISK
This note contradicts the strict ban on TypeScript defined in lines 44 and 66. Since AffineScript compiles to JS, focusing on JS runtime capabilities will provide clearer instructions for the AI.

Bun enables frozen lockfile mode automatically with
bun install --production, so the existing rule already enforces the committedbun.lock.

Update heal to match the supported Bun setup.
QUICKSTART-USER.adoc and QUICKSTART-DEV.adoc direct users to just heal. The recipe installs Deno and runs deno install, but it does not install the Bun dependencies required by .claude/CLAUDE.md. Replace these steps with the supported Bun setup, or document and scope a Deno-only exception.

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.
