policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #73
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. 2 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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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
While the PR successfully establishes Bun as a Tier 1 runtime and removes Deno, it fails to correctly implement the 'ReScript to AffineScript' terminology restoration described in the PR intent. Specifically, the enforcement rules still incorrectly ban TypeScript instead of ReScript, and the naming remains inconsistent across the policy documents.
Codacy analysis indicates the changes are technically 'up to standards', but the logic gaps regarding the migration terminology present a high risk of confusing AI assistants relying on these instructions. This divergence from the acceptance criteria should be addressed before merging.
About this PR
- The PR implementation only partially fulfills the stated intent to repair 'ReScript purge scars'. There is significant terminology drift where 'AffineScript' is introduced in some rules while 'ReScript' or 'TypeScript' remains in others (e.g., the primary language table and banned tools table). This inconsistency creates ambiguity for AI agents using this policy.
Test suggestions
- Verify Bun is listed as Tier 1 JS/TS runtime in the ALLOWED table
- Verify Deno is replaced by Bun in the BANNED table
- Verify enforcement rules mandate package.json and bun.lock
- Verify restoration of ReScript/AffineScript terminology in table rows and rules

🔴 HIGH RISK
Divergence from requirement: This rule maintains a ban on 'TypeScript' despite the PR description stating it should be updated to ban 'ReScript' files. Standardize the language naming to 'AffineScript' to match the updates on lines 29 and 62 and resolve conflicts with lines 22, 40, and 66.

🔴 HIGH RISK
Divergence from requirement: The PR description specifies this rule should be updated to 'No new ReScript files — convert .res to AffineScript', but the code still incorrectly bans 'TypeScript'. Additionally, 'ReScript' is still used in lines 22, 40, and 66, while this line uses 'AffineScript'. Standardize the naming to ensure consistent instructions for AI assistants. Suggestion: Replace all occurrences of 'ReScript' with 'AffineScript' (or vice-versa as per the final policy) to maintain a unified terminology.

Align the ReScript commands with the Bun policy. scripts/Justfile still runs the build, watch, format, and check commands through Deno's npm:rescript entry point. Run these commands through Bun, or document an explicit exception for the existing Deno tooling.

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.
