📝 WalkthroughSummary by CodeRabbit
WalkthroughThe Claude instructions replace Deno with Bun for JavaScript and TypeScript runtime, package management, dependency installation, and one-off tooling. ChangesBun runtime policy
Estimated code review effort: 1 (Trivial) | ~3 minutes Merge Risk: 🔵 Low · up to The policy now requires JavaScript packages to use Bun with a committed lockfile, but an existing package still uses npm scripts and has no bun.lock. Clarify whether it is exempt or migrate it before merging; otherwise the policy is mergeable with explicit owner awareness. Poem

Pull Request Overview
This PR successfully transitions the runtime policy to Bun as Tier 1; however, it fails to meet all the stated objectives in the PR description. Most notably, the restoration of 'blanking scars' related to ReScript and '.res' files is missing from the code changes. Additionally, while Deno is removed from the allowed list, it is not yet explicitly banned, which may cause ambiguity for AI assistants.
A high-severity issue regarding Personally Identifiable Information (PII) was identified in the copyright notice. Although the overall Codacy analysis is 'up to standards', this privacy leak and the missing implementation of acceptance criteria regarding ReScript should be addressed before merging.
About this PR
- There is a significant misalignment between the PR description and the implementation. The description claims to repair 'blanking scars' by restoring 'ReScript' text and updating rules for '.res' files, but these changes are absent from the diff. Please verify if additional files or lines were intended to be included in this PR.

Test suggestions
- Verify Bun is listed as Tier 1 and default runtime in the ALLOWED table
- Verify Deno is replaced by Bun in the BANNED table for Node.js and npm entries
- Verify enforcement rules require package.json and bun.lock manifests
- Verify restoration of ReScript mentions in BANNED table and Enforcement Rules

🟡 MEDIUM RISK
Suggestion: Since Deno is being replaced by Bun as the primary runtime, it should be explicitly added to the BANNED table to ensure the AI assistant does not use it as a fallback.

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.

Update the conflicting README guidance.
README.adoc still states in Lines 123-132 that Deno replaces Node.js and npm. These lines now state that Bun replaces them. Contributors can receive conflicting runtime instructions. Update README.adoc, or mark that section as historical.

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>

Bun official documentation --frozen-lockfile missing bun.lock behaviour
💡 Result:
When using the --frozen-lockfile flag with Bun, the behavior regarding a missing bun.lock file depends on your specific Bun version, as this behavior has seen updates to address regressions and consistent functionality [1][2]. In general, the --frozen-lockfile flag is designed to ensure reproducible installs by preventing any updates to the lockfile [3]. If the lockfile is missing, Bun's default behavior is to attempt to install dependencies from your package.json [3]. Regarding the generation of a new bun.lock file: 1. Standard Behavior: Historically, and in many contexts, running --frozen-lockfile should not create a new lockfile if one does not already exist [3][2]. It is intended to fail or operate strictly based on existing information rather than generating new artifacts [3]. 2. Bug/Regression Context: There have been documented issues where running --frozen-lockfile erroneously created a bun.lock file even when one was missing or when a different lockfile (like package-lock.json) was present [1]. 3. Fixes: Updates, such as those addressed in pull request #17481, were introduced to ensure that --frozen-lockfile does not save or generate a new lockfile, bringing the tool back to its intended behavior of strictly forbidding lockfile modification or creation [2]. If you are encountering unexpected creation of a bun.lock file while using this flag, ensure you are on the latest version of Bun, as this was specifically targeted as a fix [1][2]. Additionally, note that bun ci is equivalent to running bun install --frozen-lockfile, which also enforces this strict, non-updating behavior [3].

Define whether existing JavaScript packages are in scope.
.claude/CLAUDE.md requires package.json plus bun.lock and Bun commands, but editors/vscode/package.json has npm scripts, an empty devDependencies, and no bun.lock. State an explicit exemption, or migrate the package to the Bun contract with a committed lockfile and declared tooling. A missing lockfile does not unconditionally make --frozen-lockfile fail because Bun's behaviour is version-dependent.
