policy: Bun is tier 1, Deno is being removed — correct local CLAUDE.md - #84
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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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.
📝 WalkthroughSummary by CodeRabbit
WalkthroughThe project guidance now identifies Bun as the tier-one JavaScript/TypeScript runtime and package manager. It updates JavaScript exceptions, API references, and banned-tool mappings. ChangesBun tooling policy
Estimated code review effort: 1 (Trivial) | ~2 minutes Merge Risk: 🔵 Low · up to The policy now makes Bun the default runtime and package manager, but its wording could also be read as authorizing new TypeScript work even though TypeScript remains banned. This is a bounded, non-blocking policy ambiguity that should be clarified or explicitly accepted. Poem

state that Bun is the default runtime/package manager, while `.ts` execution
applies only to existing or interoperability tooling; preserve the separate
policy that ReScript is the primary application language and TypeScript is not
permitted for new application work.

Pull Request Overview
While this PR successfully establishes Bun as a Tier 1 runtime in several sections, the transition is incomplete. A direct contradiction exists in the 'Neural Foundations Specific' section where Deno is still listed as the preferred tool for orchestration and API servers, which offsets the ban declared earlier in the file.
Additionally, several key requirements mentioned in the intent—such as repairing corrupted text from previous purges ('blanking scars') and adding specific 'bun install' instructions—are missing from the actual changes. These gaps and the inconsistent use of 'AffineScript' versus 'ReScript' should be addressed before merging to ensure policy clarity.
About this PR
- The PR description mentions repairing 'blanking scars' (specifically the 'No new ReScript files' instruction) and adding rules for 'bun install --production' and 'bunx', but these updates are absent from the provided changes. Please ensure all intended policy repairs are included.

line 43🟡 MEDIUM RISK
The policy update to remove Deno is incomplete. The 'Neural Foundations Specific' section still lists Deno as the preferred tool for orchestration and API servers. Update this section to replace Deno with Bun to ensure consistency with the new Tier 1 runtime policy.
Test suggestions
- Verify Bun is listed as the Tier 1 replacement for Deno/Node
- Verify manifest rule (package.json + bun.lock) is explicitly defined
- Verify restoration of 'No new ReScript files' policy text
- Verify 'bun install --production' instruction is present
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify restoration of 'No new ReScript files' policy text
2. Verify 'bun install --production' instruction is present
TIP Improve review quality by adding custom instructions

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.
