policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #75
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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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 updates the project's runtime policy to establish Bun as Tier 1 and remove Deno. While the core runtime changes are present, there is an implementation gap regarding the restoration of 'ReScript' terminology in policy tables, which was noted as a requirement but is missing from the diff.
Furthermore, the description for Bun's capabilities contradicts existing project rules (Rule 1) prohibiting new TypeScript files; this needs clarification to avoid misleading AI agents. While the PR is technically 'up to standards' per Codacy, the main policy file is becoming monolithic and should be refactored for better maintenance.
About this PR
- The PR description mentions restoring 'ReScript' in policy tables and enforcement rules (specifically lines 51 and 75), but these lines appear as unchanged context in the diff. Please verify if these changes were omitted or if the base branch already contains them.
Test suggestions
- Verify Bun is listed as Tier 1 in the ALLOWED table
- Verify Deno is replaced by Bun in the BANNED/Replacement table
- Verify Rule 3 and 4 mandate package.json and bun.lock
- Verify restoration of 'ReScript' text in blanking scars (lines 51, 75)
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify restoration of 'ReScript' text in blanking scars (lines 51, 75)

🟡 MEDIUM RISK
The description for Bun contradicts Rule 1. Since new TypeScript is banned, highlighting native .ts execution as the default workflow is misleading for the AI. Clarify that Bun is the runtime target for compiled AffineScript/JS output.

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.
Mirrors the TypeScript row's own replacement cell rather than assuming the literal string, so bold, qualified and extra-column table variants are all handled without reformatting the surrounding table. Enforcement Rule 1 is untouched: standards#655 records that collision as not resolvable unilaterally. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Align the task aliases with the Bun policy.
In mise.toml, Lines [51-57] still define npm run build and npm test fallbacks. These commands can execute when the preceding command fails, which conflicts with the new rule that bans npm. Replace the fallbacks with the repository’s Bun commands, or document an explicit exception.
