📝 WalkthroughSummary by CodeRabbit
WalkthroughThe tooling policy replaces Deno with Bun as the tier-1 JavaScript/TypeScript runtime and package manager. It updates AffineScript targets, banned-tool mappings, manifest requirements, production installation, and one-off tooling guidance. ChangesBun tooling policy
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to The policy change makes Bun the default runtime and package manager, but its current installation and tool-execution guidance can allow dependency drift or execution outside the pinned dependency set. These bounded reproducibility and consistency risks should be fixed before merging. Poem

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NOT FOLDED IN: "Fallback: Nix (flake.nix)" is stale (Guix superseded Nix per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.

Bun official documentation bun install --frozen-lockfile default disabled lockfile package.json bun.lock
💡 Result:
By default, bun install does not ignore your lockfile; it uses the existing bun.lock (or legacy bun.lockb) to ensure reproducible installs [1][2]. The --frozen-lockfile flag is used to explicitly enforce that the lockfile remains unchanged [1][3]. Here are the key details regarding how bun install and --frozen-lockfile behave: 1. Default Behavior: When you run bun install, Bun reads your package.json and the existing lockfile (bun.lock) to perform a reproducible install [1][2]. If you have a lockfile, Bun respects the versions defined within it [1][3]. 2. --frozen-lockfile Flag: This flag prevents Bun from modifying the lockfile [1][3]. If your package.json has changes that would cause the lockfile to be updated (e.g., adding a dependency or changing a version range), Bun will exit with an error instead of updating the lockfile [1][4]. 3. CI/CD Usage: Bun does not automatically enable --frozen-lockfile in CI environments [1][5]. It is highly recommended to use the bun ci command in CI/CD pipelines, which is equivalent to running bun install --frozen-lockfile [1][3]. 4. Lockfile Format: As of Bun v1.2, the default lockfile format is a text-based file named bun.lock [2][6]. Previous versions used a binary format called bun.lockb [2][3]. 5. Opting Out: If you do not want Bun to save or update a lockfile, you can run bun install --no-save [2][6]. In summary, the lockfile is not "disabled" by default; it is a core feature of Bun's dependency resolution [1][2]. The --frozen-lockfile flag is simply a safety mechanism to ensure that the environment remains strictly synchronized with the committed lockfile [1][3].

Make the lockfile requirement and production install deterministic.
Require and commit both package.json and bun.lock. Use bun install --frozen-lockfile --production so Bun fails when the manifest and lockfile differ, instead of updating the lockfile during installation.

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.
