policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #65
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. 3 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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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
While this PR successfully initiates the transition to Bun as a Tier 1 runtime, several implementation issues must be addressed before merging. Most critically, the Markdown table syntax in the policy file is broken due to inconsistent pipe usage, which will prevent the documentation from rendering correctly.
There are also significant logical contradictions: the new policy mentions Bun's ability to execute TypeScript directly while a separate rule explicitly bans TypeScript. Furthermore, the transition from 'ReScript' to 'AffineScript' is incomplete and inconsistent across the file, and the enforcement rules do not match the requirements specified in the PR description (specifically regarding the ban on new ReScript files vs TypeScript files).
About this PR
- The PR description indicates the restoration of a BANNED row for 'ReScript' pointing to 'AffineScript' to repair 'blanking scars', but this change is missing from the provided diff. Additionally, ensure that the transition to 'AffineScript' is applied systematically across all documentation to avoid confusion.
Test suggestions
- Verify Bun is listed as Tier 1 and default in the ALLOWED table.
- Verify Deno is replaced by Bun in the BANNED table replacements.
- Verify the requirement for 'package.json' and 'bun.lock' in Enforcement Rules.
- Missing update of TypeScript conversion target to AffineScript.
- Verify JavaScript use case refers to AffineScript instead of ReScript.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Missing update of TypeScript conversion target to AffineScript.

🔴 HIGH RISK
Table formatting is inconsistent; new rows use a single pipe | prefix instead of the double pipe || used throughout the file, which will break the layout rendering. Additionally, the note about direct .ts execution contradicts the ban on TypeScript in line 40; this should be clarified or removed to ensure the AI assistant does not inadvertently generate TypeScript.

🟡 MEDIUM RISK
This enforcement rule has two primary issues: 1) The implementation uses 'No new TypeScript files' which contradicts the PR description's requirement to specifically ban new 'ReScript' files. 2) The terminology 'AffineScript' is introduced here while 'ReScript' is still maintained on lines 22 and 45. These should be unified to ensure policy consistency.

🟡 MEDIUM RISK
Inconsistent language definition: The JavaScript use case now references 'AffineScript', but the primary language definition at line 22 remains 'ReScript'. These must be synchronized to provide the AI with a single, unambiguous 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.
