policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #140
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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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.

Pull Request Overview
The pull request successfully updates the project policy to designate Bun as the Tier 1 runtime, correctly updating the ALLOWED and BANNED tool tables and mandating the use of Bun's manifest files. The transition from Deno is complete in terms of the requested specification.
However, a logic contradiction exists on line 55 where the description of Bun's native TypeScript support conflicts with the existing ban on new TypeScript files (Rule 1). This ambiguity may cause AI agents to disregard the restriction. Furthermore, the document references a non-existent EXTRACTION-MANIFEST.md file, which should be resolved to prevent tool errors.

.claude/CLAUDE.md
line 1🔴 HIGH RISK
The document referencesEXTRACTION-MANIFEST.md, but this file does not exist in the repository. AI agents relying on this documentation will encounter errors when attempting to locate this manifest. Verify if the file should be created or if the reference is obsolete.
line 4🟡 MEDIUM RISK
The 'never vendored' rule for sub-repositories is an absolute policy without an escape hatch. This lack of flexibility can block development if an emergency upstream fix is needed but cannot be merged immediately. Consider adding a documented exception process, such as requiring lead architect approval.
Test suggestions
- Verify Bun is listed in the ALLOWED tools table with Tier 1 status.
- Verify the requirement for package.json and bun.lock is explicitly stated in Enforcement Rules.
- Verify that bun install --production is mandated for production deps.
- Verify Deno-specific runtime/API references are removed or replaced.
- Verify Node.js/npm/pnpm/yarn are correctly mapped to Bun in the BANNED table.

🟡 MEDIUM RISK
The notes for Bun ('Default for all new work' and 'Executes .ts directly') contradict the ban on new TypeScript files in Rule 1. This should be clarified to specify that Bun is the default runtime for executing AffineScript output and permitted JS glue, rather than an invitation to use TypeScript for new work.

Align mise.toml with the banned-tool policy.
mise.toml:3,13-15 declares node, npm, yarn, and pnpm. When an agent or CI job activates mise, these commands can be installed despite .claude/CLAUDE.md:68-76 banning them. Remove or gate these entries, or document their legacy-only use.

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>

Synchronise the machine-readable policy contracts.
.claude/CLAUDE.md now selects Bun and requires package.json plus bun.lock, but .machine_readable/bot_directives/gitbot-fleet.a2ml:44-46 still denies npm/bun/yarn/pnpm dependencies and .machine_readable/contractiles/Mustfile.a2ml:25-29 still declares Deno only. Active bots or agents that read those contracts can reject the Bun workflow required here. Update those contracts in the same change, or define and enforce one precedence rule.
Also applies to: 74-77, 97-98, 107-107
