policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #64
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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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 as the default JavaScript runtime and package manager. It updates AffineScript targets, tool replacements, dependency file requirements, production installation, and one-off tool usage. ChangesBun runtime and package guidance
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to The PR makes Bun the default in local guidance, but the repository’s machine-readable contract still permits only Deno and bans Bun dependencies. These conflicting rules can lead to incorrect runtime or dependency choices, so the contract must be reconciled before merging. Poem

Pull Request Overview
While the PR successfully promotes Bun to a Tier 1 runtime, it fails to deliver on the 'ReScript restoration' mentioned in the PR description. Additionally, the update introduces a significant logical contradiction between the new Bun tool description and existing language enforcement rules.
Codacy analysis indicates the changes are technically up to standards, but from a policy alignment perspective, there are gaps that will likely cause the AI to author invalid files (TypeScript instead of AffineScript). Addressing the discrepancies in the enforcement rules is necessary before merging to maintain a consistent developer experience.
About this PR
- There is a disconnect between the PR description and the implementation. ReScript-related restorations mentioned in the 'Also repaired' section are missing from the diff, particularly in the Banned table (line 27) and Rule 1.
Test suggestions
- Verify Bun is listed as Tier 1 in the Allowed Languages table.
- Verify Deno references are replaced by Bun in the Banned table replacements.
- Confirm the requirement for package.json and bun.lock is explicitly stated in Enforcement Rules.
- Verify the restoration of ReScript-related text in the Banned table and Enforcement Rules as described in the PR summary.
Prompt proposal for missing tests

1. Verify the restoration of ReScript-related text in the Banned table and Enforcement Rules as described in the PR summary.

🟡 MEDIUM RISK
This line was not updated to restore the 'ReScript' name as specified in the 'Also repaired' section of the PR description. If the intent is to ban ReScript files as part of the restoration, this needs to be updated.

🟡 MEDIUM RISK
The description for Bun contradicts the 'No new TypeScript' rule. It identifies Bun as the 'Default for all new work' and highlights its ability to execute .ts without a build step, which directly opposes the requirement in Rule 1 to use AffineScript for all new application code. Update the entry to clarify that Bun is the runtime for compiled AffineScript (ESM) and remove the claim about direct .ts execution for new work.

Align the Bun policy with the machine-readable contract.
.machine_readable/MUST.contractile defines a hard invariant that permits Deno only and bans Bun dependencies. This conflicts with the Bun, package.json, bun.lock, and bunx requirements in .claude/CLAUDE.md. Update the contract and its enforcement path, or remove the obsolete contract.
If examples/web-project-deno.json remains supported, update it to match the Bun policy. Otherwise, mark it as legacy or remove it.

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.
