policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #660
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 NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per ADR-2026-STACK-MIGRATION) but that is a separate ruling; flagged, not changed.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
This PR successfully updates the JS/TS runtime policy to Tier 1 Bun and removes Deno as requested. However, the implementation of the ReScript-to-AffineScript transition is inconsistent and contradicts the PR's stated intent.
The primary issue is a mismatch between the 'ALLOWED Languages & Tools' tables (which still list ReScript) and the 'Enforcement Rules' (which use AffineScript). Furthermore, the PR description specifies that Rule 1 should be changed to 'No new ReScript files', but the implementation currently maintains a ban on TypeScript. These contradictions must be resolved to ensure AI agents have clear, non-conflicting instructions. Although Codacy identifies the PR as up to standards, these alignment gaps with the requirements should prevent merging in the current state.
About this PR
- There is a systemic contradiction regarding the ReScript-to-AffineScript transition. The PR intent describes a purge, but 'ReScript' remains listed as the primary application code in the main tables of both files while specific rules start referencing 'AffineScript'.
Test suggestions
- Verify 'Bun' is correctly defined as Tier 1 and Tier 1 runtime in the ALLOWED table.
- Verify Enforcement Rules explicitly require package.json and bun.lock.
- Verify all references to Deno (allowed or replacements) are removed or updated.
- Verify ReScript is phased out for AffineScript in the 'Enforcement Rules' and 'ALLOWED' table as per the 'ReScript purge' intent.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify ReScript is phased out for AffineScript in the 'Enforcement Rules' and 'ALLOWED' table as per the 'ReScript purge' intent.

🟡 MEDIUM RISK
The PR description specifies Rule 1 should be 'No new ReScript files', but the current implementation keeps it as 'No new TypeScript files'. Additionally, this rule uses the term 'AffineScript' which conflicts with the 'ReScript' designation in the main language table at line 22.

This line still lists ReScript as the primary language, which contradicts the 'ReScript purge' described in the PR summary. If the transition is in effect, this should be updated to AffineScript to maintain consistency with the new enforcement rules.

⚪ LOW RISK
Nitpick: The enforcement rule references 'AffineScript', while the language table at line 23 still lists 'ReScript'. Use the following prompt to fix: Update the 'ALLOWED Languages & Tools' table in meta-a2ml/.claude/CLAUDE.md to replace 'ReScript' with 'AffineScript'.
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).

Remove the retired Bun row from the banned table.
The table has two columns, but Line 45 has three cells. This triggers MD056 and leaves Bun inside the banned-tools table despite its tier-1 allowed row. Delete the retired row instead of keeping a contradictory table entry.

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>

The existing ReScript row on Line 135 already defines the same replacement. Keep one row and merge the migration-path note into it. Duplicate policy entries can create ambiguity for readers and table-based tooling.

This branch and #655 both modified .claude/CLAUDE.md, which would conflict on merge and would also overwrite #655's much richer correction (the owner-ruling blockquote, the Deno row moved out of ALLOWED into BANNED, and the TypeScript tightening) with this sweep's mechanical row edits.
