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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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.
📝 WalkthroughSummary by CodeRabbit
WalkthroughThe change updates ChangesRuntime policy
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to The policy now requires Bun manifests and dependency handling, but the repository’s CI still rejects projects with runtime dependencies and the production backend image still uses npm without bun.lock. This can cause policy-compliant projects to fail checks or diverge from the documented build process, so the changes should be aligned before merge. Poem

Bun install official documentation --frozen-lockfile default CI lockfile update behaviour
💡 Result:
In Bun, the --frozen-lockfile flag is used to ensure reproducible installations by preventing any modifications to the lockfile [1][2]. When this flag is enabled, Bun installs the exact versions specified in the bun.lock file [1][3]. If the package.json file and the lockfile are out of sync, or if an update to the lockfile would be required to satisfy the dependencies, Bun will exit with an error [1][2]. Regarding CI/CD environments: - Bun does not automatically enable --frozen-lockfile in CI/CD by default [1][2]. - To ensure reproducible builds in CI/CD, it is recommended to use the bun ci command [1][3]. - The bun ci command is functionally equivalent to running bun install --frozen-lockfile [1][3]. It will install the exact versions listed in the lockfile and fail the process if the package.json does not match the current lockfile [1][2]. To use these features effectively, you must commit your bun.lock file to version control [1][3]. If no lockfile exists, --frozen-lockfile will install dependencies based on package.json without attempting to generate or write a new lockfile [1][2].

Align backend/api/Containerfile with the Bun lockfile policy.
The Containerfile uses the banned node:18-alpine base image and npm ci. Its COPY package*.json ./ instruction does not copy bun.lock. Use Bun with bun install --production --frozen-lockfile or bun ci. If this service is not Bun-managed, scope the policy accordingly.

Pull Request Overview
The PR successfully initiates the transition to Bun as the primary JavaScript/TypeScript runtime. However, it fails to fulfill all stated objectives in the PR description, most notably the repair of 'blanking scars' and the update of Rule #1 to reflect the ReScript transition. Furthermore, a logical contradiction has been introduced: the documentation for Bun highlights its ability to execute TypeScript directly, which conflicts with the standing policy in Rule #1 that prohibits new TypeScript files. These inconsistencies must be resolved to ensure the repository's governing policies remain clear and actionable.
About this PR
- The PR implementation is incomplete relative to its description. The 'blanking scars' from the ReScript purge remain unaddressed, and the transition of Rule #1 from 'No new TypeScript' to 'No new ReScript' is missing from the code.
Test suggestions
- Verify Bun is defined as Tier 1 and the default for new work
- Verify Node.js/npm/yarn are listed as banned with Bun as the replacement
- Verify Deno-specific rules (no package.json, no node_modules) are replaced with Bun manifest requirements
- Verify the repair of ReScript 'blanking scars' as claimed in the description

🟡 MEDIUM RISK
The claim that Bun 'Executes .ts directly, no build step' contradicts Rule #1 (line 66), which bans new TypeScript files, and the requirement for AffineScript to compile to JS. This inconsistency may confuse agents regarding whether TypeScript is permitted.

⚪ LOW RISK
The PR description claims Rule #1 was updated to 'No new ReScript files', but the implementation still says 'No new TypeScript files'.
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. ReScript was absent from the BANNED table although canon bans it (destination AffineScript), so the table read as permitting it. Enforcement Rule 3 said `bun install --production` with no `--frozen-lockfile`, so a lockfile mismatch silently re-resolved instead of failing, which defeats the point of committing `bun.lock`. 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 the CI policy with the Bun manifest rule.
.claude/CLAUDE.md now requires package.json for JavaScript runtime dependencies, but .github/workflows/language-policy.yml Lines [68-77] still fails when package.json contains "dependencies". A project that follows this rule will fail its language-policy check when it adds a runtime dependency. Update the workflow to accept Bun-managed package.json and bun.lock projects, or scope this rule away from paths checked by that workflow.
