Pull Request Overview
While this PR correctly updates the project's dependency on Bun and mandates the use of bun.lock files, it contains major discrepancies between the PR description and the code diff. Several promised changes, such as the restoration of ReScript to the BANNED table and corrections to Rule #1, are missing entirely from the current commit.
Codacy analysis indicates the file is 'up to standards', but internal review identifies a critical documentation inconsistency: the description of Bun as having 'no build step' contradicts the project's core requirement for AffineScript (which requires compilation). Furthermore, an instance of PII (personal email) was identified at the start of the file that should be redacted for security.
About this PR
- There is a significant discrepancy between the PR description and the provided diff. The description claims to restore 'ReScript' to the BANNED table and fix Rule #1 text (lines 44 and 66), but these lines remain unchanged in the current diff. Additionally, the claimed correction for Line 33 ('Only where cannot' -> 'Only where AffineScript cannot') appears unnecessary as the existing code already contains the word 'AffineScript'. Please ensure all intended changes are staged and committed.

Test suggestions
- Bun is added to the ALLOWED list with Tier 1 status and usage notes
- Deno is removed from ALLOWED and BANNED replacement columns
- Manifest requirement rule (package.json + bun.lock) is present
- Production dependency installation rule is present
- ReScript is restored to the BANNED table as a row/cell
- Rule #1 is corrected to reference ReScript as per description
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. ReScript is restored to the BANNED table as a row/cell
2. Rule #1 is corrected to reference ReScript as per description

🟡 MEDIUM RISK
Suggestion: Deno should be explicitly added to the BANNED list to reflect the policy change and prevent the AI agent from using it or its legacy configuration formats.

🟡 MEDIUM RISK
Suggestion: The phrase "Executes .ts directly, no build step" contradicts the requirement for AffineScript (which involves a compilation step) and the ban on new TypeScript files. Clarify that Bun runs the compiled ESM output and legacy code to prevent the AI from bypassing the project's language policy.

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.

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).
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>
