policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #76
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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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
The pull request successfully promotes Bun to a Tier 1 runtime and updates the package management manifests. However, there are significant discrepancies between the implementation and the PR description.
Specifically, the 'blanking scars' repair for ReScript—intended to restore references to ReScript in Rule 1 and the policy tables—is missing. Additionally, while the PR intent is to remove Deno, it has not been explicitly added to the BANNED tools table, which is necessary for clear policy enforcement. Although Codacy indicates the changes are up to standards, these alignment gaps prevent the PR from fully satisfying its requirements.
About this PR
- The implementation fails to address the 'repaired: blanking scars from the ReScript purge' section of the PR description. References to ReScript in the policy tables and enforcement rules (specifically Rule 1) have not been restored.
Test suggestions
- Bun is defined as Tier 1 and default in the ALLOWED table
- Deno is replaced by Bun in the Banned tools section
- Enforcement rules are updated to require package.json and bun.lock
- Rule 1 is updated to reference ReScript instead of TypeScript per the 'blanking scars' repair

🟡 MEDIUM RISK
This line does not reflect the 'ReScript purge' repair described in the PR; it still references TypeScript instead of ReScript.

🟡 MEDIUM RISK
Suggestion: The PR description states Deno is being removed, but it is missing from the 'BANNED' table. Explicitly banning it ensures consistency with the removal of other JS runtimes/package managers like Node.js and npm.

- Line 27: Clarify the Bun row in the runtime table and Enforcement rule 1 so
they no longer conflict: state that Bun executes existing TypeScript files
directly while the prohibition on adding new TypeScript files remains in effect.
- Line 77: Update the JS dependencies guidance in CLAUDE.md to prohibit
unconstrained bunx tool execution; require one-off tools to be declared as
devDependencies and invoked with bunx --no-install, or otherwise specify an
exact version with an integrity check to preserve lockfile-backed, SHA-pinned
dependencies.

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.
