policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #259
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. 6 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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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 change updates six policy documents. It replaces Deno with Bun as the tier-one JavaScript runtime and package manager. It requires ChangesBun policy migration
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The PR makes Bun the required runtime, but current repository guidance still permits non-reproducible production installs and cleanup automation still conflicts by removing Bun while retaining Deno. These concrete consistency and reproducibility issues should be corrected or explicitly accepted before merging. Poem

Pull Request Overview
The PR successfully establishes Bun as the Tier 1 JS/TS runtime and updates the banned tool list as intended. The enforcement rules now correctly include requirements for package.json and bun.lock manifests. However, there is a significant discrepancy: the PR description mentions restoring ReScript policy references and repairing enforcement rules affected by previous 'purges,' but these changes are entirely missing from the diff. Additionally, to comply with existing security policies regarding SHA-pinned dependencies, production install commands should be updated to use frozen lockfiles. Codacy analysis confirms the changes are otherwise up to standards.
About this PR
- The restoration of ReScript rows in policy tables and the repair of enforcement rule headers (e.g., 'No new ReScript files') described in the PR intent are missing from the files. Please verify if these changes were omitted by mistake.
Test suggestions
- Bun is listed as the Tier 1 runtime in all policy files
- Banned packages (npm, Node.js, yarn) point to Bun as the replacement
- Manifest requirements (package.json and bun.lock) are explicitly stated in enforcement rules
- ReScript row restoration in the banned policy tables
- ReScript enforcement rule repair ('No new ReScript files')
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. ReScript row restoration in the banned policy tables
2. ReScript enforcement rule repair ('No new ReScript files')

Update cleanup-banned-runtimes.sh to preserve Bun.
When asdf lists Bun, the script uninstalls Bun and removes its plugin. This conflicts with Bun’s tier-one status. Remove the Bun cleanup step and the Deno replacement message, or remove this script from supported automation.

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.
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>
