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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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.

Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to This change makes Bun the required local runtime while the README, build configuration, and test instructions still direct contributors to Deno, creating conflicting workflows and making the PR not merge-ready until those paths are synchronized or explicitly documented as supported. One-off tooling may also invoke Node unless the Bun-specific execution mode is required. Poem

Pull Request Overview
The PR successfully updates the policy to establish Bun as the Tier 1 runtime and mandates standard manifest files. However, there is a significant gap: the PR description claims to repair 'blanking scars' from a previous ReScript purge, but these changes are absent from the diff.
Additionally, the documentation for Bun introduces potential confusion for AI assistants by highlighting direct TypeScript execution as a benefit, which contradicts the project's strict ban on new TypeScript files (Rule 1) and the requirement for AffineScript compilation. While Codacy results are up to standards, these alignment and logic issues should be addressed before merging.
About this PR
- The PR description indicates that this change restores missing ReScript-related text to tables and enforcement rules (e.g., converting 'No new files' back to 'No new ReScript files'). However, these restorations are not present in the current diff (see lines 44 and 66). Please verify if these changes were omitted from the commit.
Test suggestions
- Verify Bun is listed as Tier 1 and marked as the default for new work in the ALLOWED table.
- Verify Node.js, npm, and pnpm/yarn are mapped to Bun in the BANNED table.
- Verify Enforcement Rule 2 explicitly requires package.json and bun.lock manifests.
- Verify restoration of ReScript text in BANNED rows and enforcement rules as claimed in the description.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify restoration of ReScript text in BANNED rows and enforcement rules as claimed in the description.

🟡 MEDIUM RISK
This description contradicts Rule 1 and the AffineScript policy. Since new TypeScript is banned and AffineScript requires compilation to JS, the 'no build step' and 'executes .ts directly' benefits are not applicable to the primary development workflow. Consider updating the description to reflect that Bun executes the compiled JavaScript output from AffineScript.

⚪ LOW RISK
Suggestion: Since Deno is being replaced by Bun as the Tier 1 runtime, it should be explicitly added to the 'Banned' table to prevent accidental usage, especially as it was the previous project standard.
Try running the following prompt in your coding agent:
Add a row to the Banned table in .claude/CLAUDE.md for Deno, indicating Bun as its replacement.

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Synchronise the policy with active setup and test instructions.
After this change, .claude/CLAUDE.md requires Bun, but README.md:72-73 still says that Deno is required, stapeln.toml:28-37 still installs Deno and runs deno install and deno task res:build, and TEST-NEEDS.md:9-28 still documents deno task test.
Update these active consumers in this migration, or explicitly state that the existing Deno build and test paths remain supported. Otherwise, contributors cannot follow one consistent project policy.

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.
