policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #54
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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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 project guidance replaces Deno with Bun for JavaScript and TypeScript execution, dependency management, enforcement rules, and one-off tooling. It also updates JavaScript guidance from ReScript and Deno APIs to AffineScript and Bun APIs. ChangesRuntime policy
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to The policy now prioritizes Bun, but repository enforcement still directs contributors toward Deno and rejects Bun-related lockfiles, so following the documented policy can fail repository checks. The policy also names two different replacement targets for TypeScript. Merge should wait for enforcement synchronization and one deterministic language target. Poem

Pull Request Overview
This PR successfully updates the runtime policy to promote Bun to Tier 1 and remove Deno. It correctly mandates the use of package.json and bun.lock for dependency management.
The primary concern is the incomplete transition from 'ReScript' to 'AffineScript'. The policy currently contains contradictory instructions—defining 'ReScript' as the primary application code in one section while referencing 'AffineScript' as the target in others. Additionally, the PR description indicates that Rule 1 should be changed to 'No new ReScript files', but the code maintains 'No new TypeScript files'.
These inconsistencies should be resolved to provide a clear, machine-readable policy for AI assistants. Codacy analysis indicates the file is up to standards, but these logic and terminology gaps in the instructions are significant enough to warrant revision.
About this PR
- The document currently presents a contradictory language policy. While some sections point to AffineScript, 'ReScript' is still listed as the primary application code (line 22) and the replacement for TypeScript (line 40). These must be unified to prevent AI agents from generating code in the wrong format or following outdated standards.
- The PR description references specific changes to the BANNED table (regarding ReScript and AffineScript) that do not appear in the code changes. Please verify if these changes were missed or if the description needs updating.
Test suggestions
- Bun is promoted to tier 1 in the ALLOWED languages table
- Deno is removed and replaced by Bun in the BANNED replacements table
- Enforcement Rule 2 is updated to mandate package.json and bun.lock
- Enforcement Rule 3 is updated to specify production installation via Bun
- JavaScript use-case notes are updated to reference AffineScript and Bun APIs

🟡 MEDIUM RISK
The implementation on this line diverges from the PR description. The description claims the rule is 'No new ReScript files', specifically regarding the conversion of '.res' files to '.affine', but the code currently states 'No new TypeScript files'.

🟡 MEDIUM RISK
The language policy is inconsistent. While lines 29 and 62 have been updated to 'AffineScript', references in lines 22, 40, and 66 still point to 'ReScript'. This creates a contradiction in the instructions for the AI assistant. Standardize the language policy by replacing all remaining instances of 'ReScript' with 'AffineScript' (specifically in lines 22, 40, and 66) to ensure consistent instructions for code conversion and application development.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Use one replacement language throughout the policy.
This file now names ReScript and AffineScript as the replacement for TypeScript. Line 40 maps TypeScript to ReScript, and Line 22 still calls ReScript the primary application language, but these changed rules direct migration and JavaScript fallback to AffineScript. Align the table and rules so assistants receive one deterministic migration target.

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.
Addresses the two live static-analysis findings on this PR, across every subproject CLAUDE.md in this repository. ReScript was absent from the BANNED table although canon bans it (destination AffineScript). Enforcement Rule 3 omitted `--frozen-lockfile`, so a lockfile mismatch silently re-resolved instead of failing. Enforcement Rule 1 is deliberately untouched: standards#655 records that collision as not resolvable unilaterally. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Synchronise repository enforcement with the Bun policy.
ipv6-only/Mustfile.epx still allows Deno and bans Bun. ipv6-only/.github/workflows/ci.yml and ipv6-only/scripts/pre-commit still direct contributors to Deno and reject Bun-related lockfiles. Following these new instructions can therefore fail the repository’s own enforcement. Update those enforcement files before making Bun tier 1.
