policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #78
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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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 language policy changes the JavaScript and TypeScript runtime from Deno to Bun. It updates the allowed and banned tool tables, dependency requirements, installation commands, and one-off tooling guidance. ChangesBun runtime policy
Estimated code review effort: 1 (Trivial) | ~3 minutes Merge Risk: 🔵 Low · up to The policy now directs one-off JavaScript tooling through bunx, but without a version pin those commands may resolve changing package versions outside the repository lockfile. This is a bounded risk and the change is mergeable with owner awareness, though pinning the tool or declaring it in devDependencies is advisable. Suggested reviewers: Poem

Pull Request Overview
The PR effectively promotes Bun to a Tier 1 runtime and establishes necessary enforcement rules for package management and production deployments. However, there is a critical discrepancy: the PR description claims to repair 'blanking scars' from a previous ReScript purge, but these changes (such as updating Rule 1 to mention '.res' files) are not present in the diff.
Furthermore, while Deno is removed from the allowed tools, it should be explicitly added to the BANNED table to ensure consistency with the project's policy on prohibited technologies.
About this PR
- There is a misalignment between the PR description and the code. The description mentions repairing ReScript 'blanking scars' and updating Rule 1, but the code changes only reflect the Bun/Deno transition. Please ensure the ReScript-related repairs are included as intended.
Test suggestions
- Verify Bun is defined as the default Tier 1 runtime in the Language Policy table.
- Verify Deno is removed from the Allowed list and Node/npm/pnpm/yarn replacements point to Bun.
- Verify the Enforcement Rules section requires package.json/bun.lock and specifies production install commands.
- Verify 'blanking scars' are repaired (e.g., restoring 'ReScript' in banned rows and updating Rule 1 to 'No new ReScript files')
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify 'blanking scars' are repaired (e.g., restoring 'ReScript' in banned rows and updating Rule 1 to 'No new ReScript files')

🟡 MEDIUM RISK
This line does not reflect the 'ReScript purge repair' described in the PR summary. The description claims this was changed to 'No new ReScript files' and to convert '.res' files, but the implementation still refers to TypeScript.

🟡 MEDIUM RISK
Suggestion: Add Deno to the BANNED table to ensure it is not used in the project, consistent with the policy shift described in the PR title.
Try running the following prompt in your coding agent:
Add a row for 'Deno' to the BANNED table in .claude/CLAUDE.md with 'Bun' as the replacement.

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.
