policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #90
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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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.

Align the Bun policy with repository automation.
The new policy bans npm and requires package.json plus bun.lock, but .github/workflows/ci.yml Lines 59-87 still provisions Node.js, caches frontend/package-lock.json, and runs npm ci. A dependency change that follows this policy can therefore use a lockfile that CI does not validate. Update the workflow to use Bun, or scope this policy to workspaces that have migrated.
Also applies to: 49-51, 60-60

Pull Request Overview
This PR successfully promotes Bun to a Tier 1 runtime and removes Deno-related tooling, aligning with the updated project policy. The Codacy analysis confirms the changes are up to standards with no new quality issues detected.
However, a significant inconsistency exists in the transition from 'ReScript' to 'AffineScript'. While the rename has started in some sections (lines 16 and 49), the majority of the document—including the primary language table and specific enforcement rules—still uses the old name. This naming conflict should be resolved to ensure the AI assistant receives clear, unambiguous instructions.
About this PR
- The PR introduces a discrepancy between 'ReScript' and 'AffineScript'. For an AI instruction file like CLAUDE.md, this inconsistency is likely to cause confusion about the preferred language name and standard.
Test suggestions
- Verify Bun is established as the primary runtime with manifest requirements
- Verify Deno and its associated tools (npm/pnpm/yarn) map to Bun as the replacement
- Verify consistency in language naming for the ReScript to AffineScript transition
Prompt proposal for missing tests

🟡 MEDIUM RISK
Inconsistency: This rule introduces 'AffineScript' as the target for TypeScript conversion, but the primary language entry (line 9) and rule 5 (line 53) still use 'ReScript'. All references should be synchronized to prevent agent confusion.

🟡 MEDIUM RISK
The language policy is now inconsistent. While this line and line 49 use 'AffineScript', the primary language table (line 9), the TypeScript/Python replacement rules (lines 27, 32), and the mobile enforcement rule (line 53) still use 'ReScript'. These should be unified to ensure the AI follows a single consistent language standard.
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>

…ation (#91) .claude/CLAUDE.md was left half-migrated, and #90 landed the Bun/Deno swap on top of it, so main directed new application code at ReScript — a language canon bans — in the same file that bans Deno and mandates Bun. The file contradicted itself, not just canon: line 9 called ReScript "Primary application code" while line 16 already said JavaScript is for use "Only where AffineScript cannot" and line 20 described OCaml as the "AffineScript compiler". Half of it had migrated and half had not, which is why the fleet sweep passed over it — a half-migrated file looks current, because the modern half matches. Aligned with ratified canon (ReScript banned, destination AffineScript): primary language, the banned-table row, the Python replacement, the Tauri web-UI note and Enforcement Rule 5 all now say AffineScript, and ReScript gains its own banned row. The last two were found only by grepping EVERY remaining mention after the table edits — stopping at the tables would have left ReScript prescribed as a destination in the prose, which is how the file reached this state. Enforcement Rule 1 untouched. Verified: the 3 failing checks are pre-existing on main and unreachable by a Markdown policy edit. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
