policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #63
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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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.

Update CI to enforce the Bun dependency contract.
.gitlab-ci.yml uses node:20 and runs npm ci in extension. This does not enforce the documented bun.lock and bun install --production contract. Update CI to use Bun, or document an explicit CI exception in .claude/CLAUDE.md.

Pull Request Overview
The PR successfully establishes Bun as a Tier 1 runtime and mandates manifest-based dependency management. However, the migration from Deno is inconsistent; several sections—including the host summary and the JavaScript Exemptions table—still mandate Deno for primary components like the CLI and server. This creates a contradictory policy that will confuse AI agents. Additionally, although the PR description claims to restore ReScript policy markers ('No new ReScript files'), the implementation still references TypeScript on line 65. While Codacy identifies the PR as being up to standards, these logical contradictions and missing requirements should be addressed before merging.
About this PR
- There is a significant policy inconsistency: Deno is listed as being replaced by Bun in the Banned table, yet the JavaScript Exemptions table still explicitly defines Deno as the required runtime for all primary project components (CLI, server, tests).
- The PR description claims to repair 'blanking scars from the ReScript purge' by restoring 'No new ReScript files' rules, but these changes are absent from the file; line 65 still mandates 'No new TypeScript files'.

line 11🟡 MEDIUM RISK
The project summary still identifies Deno as the 'current runtime surface'. To maintain consistency with the transition to Bun, this should be updated. Additionally, adding an escape hatch for host code rules improves clarity.This might be a simple fix:
Host: **ReScript host removed** — ReScript remains only as a legacy *target* language in correspondence content (cartridges/examples); it must not be used for host code without explicit architecture review. The current runtime surface is **Bun + cartridge data**; **AffineScript** is the future host and a first-class target (Zig FFI + Idris2 ABI seams).
line 75-84🟡 MEDIUM RISK
Suggestion: The 'JavaScript Exemptions' section contains multiple references to Deno in the policy statement and rationales. These should be updated to Bun to maintain consistency with the new project policy. Try running the following prompt in your IDE agent:Update the 'JavaScript Exemptions' section (lines 75-84) in .claude/CLAUDE.md to replace 'Deno' with 'Bun' in rationales and policy statements, ensuring the logic for allowing JS remains consistent with Bun being the new tier-1 runtime.
Test suggestions
- Inclusion of Bun in the ALLOWED table
- Removal of Deno as the primary JS replacement in the BANNED table
- Enforcement of manifest-based dependency management (package.json + bun.lock)
- Restoration of 'No new ReScript files' rule and '.res' conversion mentions

🔴 HIGH RISK
The transition to Bun is incomplete. While Deno has been removed from the 'ALLOWED' table, it was not added to the 'BANNED' table, creating policy ambiguity. Please explicitly add Deno to the BANNED table with Bun as the recommended replacement.

🟡 MEDIUM RISK
This line does not reflect the ReScript restoration mentioned in the PR description (converting .res files); it still refers only to TypeScript.
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.
