📝 WalkthroughSummary by CodeRabbit
WalkthroughThe tooling policy now uses Bun instead of Deno for JavaScript and TypeScript execution, AffineScript targets, JavaScript glue, dependency enforcement, production installs, and one-off tooling. ChangesBun tooling policy
Estimated code review effort: 1 (Trivial) | ~3 minutes Merge Risk: ⚪ Minimal · up to This localized policy-only change updates the documented JavaScript runtime and dependency-management guidance without modifying code, workflows, or build files; no actionable merge-blocking risk remains beyond normal checks and review.

Pull Request Overview
The PR successfully establishes Bun as the Tier 1 runtime and updates enforcement rules for dependency management. However, there is a significant discrepancy between the PR description and the actual changes. The description claims to restore 'ReScript' references to Rule 1 and the Banned table to fix 'blanking scars,' yet these modifications are missing from the code diff.
Additionally, while Deno has been removed from the list of allowed tools, it has not been added to the Banned table. This omission leaves the policy incomplete, as the Banned table should explicitly redirect contributors from deprecated tools like Deno to the new standard, Bun.
About this PR
- The PR description mentions repairing 'blanking scars' by restoring 'ReScript' in Rule 1 and adding a row for it in the BANNED table. These changes are absent from the current diff, where Rule 1 still references 'TypeScript' and the BANNED table lacks the ReScript entry.
Test suggestions
- Bun is listed in the ALLOWED table as Tier 1
- BANNED table redirects Node.js, npm, and pnpm/yarn to Bun
- Enforcement Rule 2 mandates package.json and bun.lock
- Enforcement Rule 3 mandates production installs via 'bun install --production'
- Rule 1 is updated to reference ReScript as per the PR description
- A BANNED row for ReScript is restored as per the PR description
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Rule 1 is updated to reference ReScript as per the PR description
2. A BANNED row for ReScript is restored as per the PR description
Low confidence findings
- The PR description's 'was' state for several lines (specifically regarding Rule 1 and JavaScript notes) contradicts the actual content of the file prior to this change. This suggests the file state might be different than assumed in the PR summary.

🟡 MEDIUM RISK
Suggestion: Add Deno to the Banned table to complete the policy transition.

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.

Compare
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).
