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 agents read first and it currently says the opposite, so it
is corrected before any repo is touched - otherwise every future agent
re-derives the wrong conclusion from the governing document.
:89 Deno "tier 2, grandfathered, need not migrate"
-> BEING REMOVED; existing projects must migrate to Bun, and where Bun
genuinely cannot be used the reason must be DOCUMENTED, not left
silently on Deno
:187 "No package.json for runtime deps - use deno.json imports"
-> Use package.json + bun.lock; Bun is npm-compatible and a manifest is
REQUIRED
:188 "No node_modules in production - Deno caches automatically"
-> bun install --production, pinned via bun.lock
:198 "JS deps: Deno (deno.json imports)"
-> JS deps: Bun (package.json + bun.lock), bunx for one-off tooling
:182 portable Deno CLI scripts are the convert-now bucket
-> ...and anything not yet portable to AffineScript moves to Bun
WHY :187 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 is the worked example: its sources import zod and glob,
it had NO manifest of any kind, and it could not build under ANY toolchain.
Fixed in ubicity#107 by deriving a manifest from the imports; the rule that
caused it is fixed here.
Policy text only - no code, no workflows. The policy table (30 rows) and
blockquote structure are intact.
NOTED, NOT CHANGED: :197 still reads "Fallback: Nix (flake.nix)". Nix was
deprecated for Guix by ADR-2026-STACK-MIGRATION, so that looks stale too, but
it is a separate ruling and is not folded into a Deno/Bun correction.
Follow-on: 30 repos carry a live deno.json - working task runners, not orphaned
config - tracked separately for migration with documented exceptions.
Review feedback on #655 plus a tightened owner ruling. 1. NO TYPESCRIPT (owner, 2026-08-27). Asked about the Bun row advertising direct .ts execution, the owner ruled: "no typescript ... that should not exist at all." Every .ts reference is removed from the Bun row, including "JS/TS" in its label; it now reads "JS runtime". The blockquote sentence "TypeScript is permitted only where AffineScript cannot reach" is marked TOO PERMISSIVE. FLAGGED, NOT RESOLVED: this collides with the "TypeScript Exemptions (Approved)" table, which documents real technical carve-outs (.d.ts files, the npm/Node-native VS Code extension host, MCP/LSP glue). Those are not stylistic and cannot simply be deleted, so they are left standing and marked for an explicit owner decision rather than settled unilaterally. 2. DENO MOVED OUT OF ALLOWED INTO BANNED (codacy, #655). A struck-through row in an ALLOWED table is ambiguous to the agents that read this file - codacy raised exactly that. Deno now appears once, in BANNED, carrying the ruling and pointing at the #658 assessment. 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. 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). "Remove the historical commentary" - the history is why the file was wrong before, and deleting it invites the same drift back. STILL FLAGGED, unchanged: "Fallback: Nix (flake.nix)" is stale under ADR-2026-STACK-MIGRATION, but that is a separate ruling and is deliberately not folded into a Deno/Bun change.
Owner ruling 2026-08-27 (#659): keep the full policy text in each repo, but detect divergence from the canonical document. WHY. The language policy is duplicated into ~372 per-repo .claude/CLAUDE.md files across 131 repos. A census on 2026-08-26 found 868 of them still listed Bun as BANNED with Deno as its replacement - the exact inverse of the standing ruling - and NOTHING HAD EVER DETECTED IT. Correcting `standards` fixes one copy of ~372; agents read the local one. Detection was the missing piece, not the copy. WHY ASSERTIONS, NOT A GENERATOR. The copies are legitimately not identical - repos carry their own exemption tables, architecture notes and carve-outs. A byte-for-byte generator would be permanently red and would be disabled within a week. This gate asserts the INVARIANTS the policy must satisfy, whatever the surrounding wording. WHAT IT CATCHES - `| Bun | Deno |` Bun banned - the inversion nobody detected - "No package.json for runtime deps" / "deno.json imports" forbids declaring dependencies at all; this is why hyperpolymath/ubicity had NO manifest and could not build under ANY toolchain - "Executes .ts directly" / "JS/TS runtime" advertises TypeScript (owner ruling 2026-08-27: it "should not exist at all") - `| | X |`, `| **** |`, "No new files", "Only where cannot" blanking scars from bulk substitution - the same class that produced `rm -rf /lib` - `| AffineScript | AffineScript |` a rule banning the language it mandates - missing Bun row / missing Deno-in-BANNED SELF-TESTED with controls, so it cannot join the estate's fake-gate collection: a compliant file PASSES, and each of the five defect classes above is independently CAUGHT. Verified before commit.
First run of the drift gate against the 129-repo fleet found 4 divergences. Three
were real and are fixed at source (ambientops, developer-ecosystem, dotfiles#40).
Two were the gate's own false positives, fixed here.
The gate required table rows written with single spaces:
^\| \*\*Bun\*\* \|
^\| \*?\*?Deno\*?\*? \| Bun \|
Real estate files do not all look like that:
1. COLUMN-PADDED tables - `| **Bun** | ... |` (ambientops
recovery/operating-theatre). Content correct, gate said missing.
2. BULLET LISTS instead of tables - `- Deno (use Bun)` (developer-ecosystem
rescript-ecosystem/packages/core/env). A perfectly clear policy statement
that no table regex can match.
Both now accepted. This matters more than the two files: a gate that fails
correct content is a gate that gets disabled, and this estate already has a
documented history of gates nobody trusts.
CONTROLS re-run and all four pass: padded-compliant PASSES, bullet-compliant
PASSES, bullet-form missing-Deno CAUGHT, inverted `| Bun | Deno |` CAUGHT.
Fleet: 127/129 pass, the 2 remaining being this repo's own copy (owned by #655)
and a stale clone.
Third false-positive class from running the gate against real files. The gate flagged the corrected governing document itself, twice - at a blockquote explaining what the old rule said, and at the corrected rule that quotes its own predecessor parenthetically. Both are the document explaining what it replaced. That matters because #655 deliberately KEEPS that history: "the history is why the file was wrong before, and deleting it invites the same drift back". A gate that punishes a document for explaining itself pushes maintainers to delete the explanation - the opposite of the intent. `live()` now strips blockquote lines and lines where the phrase appears inside quotation marks (straight or typographic) before matching. CONTROLS, all passing: quoted-in-blockquote PASSES, quoted-inline PASSES, and a LIVE stale rule is still CAUGHT. Together with the previous commit the gate now handles: padded tables, bullet lists instead of tables, and quoted history - while still catching inverted bans, blanked cells, TypeScript advertisement and missing Deno bans.
MEASURED 2026-08-27 across the estate: **481 workflow files in 134 repos do not
parse at all**, so those gates have never executed. developer-ecosystem alone
holds 122.
A workflow that cannot be loaded produces NO CHECK RUN. It is therefore invisible
to `?status=failure` sweeps and to `gh pr checks` - the gate never runs, and its
silence is indistinguishable from success. That is why this went unnoticed: there
was nothing red to find.
Causes, from the survey:
245 mapping values are not allowed in this context
137 while scanning a simple key ... could not find expected ':'
73 while parsing a block mapping
6 found unexpected end of stream (unterminated quote)
3 control characters are not allowed
The last class is the instructive one: a literal BACKSPACE byte (0x08) committed
inside a regex in developer-ecosystem. The estate's own invisible-character
linter reported that file clean, because its pattern could not match control
characters (empty-linter#70).
The gate reports the parser's own error, and additionally names control
characters where present, since those are the least obvious cause.
Falls back yq -> python3+pyyaml -> ruby, and warns rather than failing if no
parser is available, so it cannot become a gate that blocks for want of a tool.
CONTROLS, all verified before commit:
valid workflow -> PASS
"mapping values" error (245 real) -> CAUGHT
unterminated quote (6 real) -> CAUGHT
backspace byte (the real defect) -> CAUGHT, and names the cause
back to clean -> PASS
The SARIF filter used a literal NUL byte (0x00) inside a jq string as a field separator. Deliberate and functional - but it made this the only first-party file that empty-linter enforcement would flag, and a raw control byte in source is indistinguishable from corruption to a scanner. jq interprets the backslash-u0000 escape inside its own strings, so the emitted separator is byte-identical while the script file becomes pure printable ASCII. VERIFIED: jq -r with that escape between two fields emits 78 00 79. With this and the evangeliser rewrite, empty-linter enforcement lands green estate-wide with ZERO allowlist entries.

Pull Request Overview
This review identifies a critical discrepancy: the fix described in the PR title regarding jq NUL escapes is entirely missing from the code changes. Instead, the PR introduces a language policy shift promoting Bun to Tier 1 and banning Deno, along with two Shell-based CI gate scripts.
While Codacy marks this PR as up to standards, the manual review has surfaced major logic issues in the implementation of the new scripts. The check-language-policy.sh script fails to correctly parse the Markdown table structure it targets, and several regex-based checks use non-portable syntax that will break on macOS or minimal Linux distributions. These issues must be addressed to ensure the policy enforcement is reliable across the estate.
About this PR
- There is a severe mismatch between the PR title ('fix: replace a literal NUL with the jq backslash-u0000 escape') and the actual code changes. The described jq fix is absent, and the PR instead contains language policy updates and CI scripts. Please ensure the PR title reflects the contents or include the missing fix.
Test suggestions
- Verify Bun is established as Tier 1/Default in CLAUDE.md
- Verify Deno is moved to BANNED with Bun as the replacement
- Verify TypeScript advertisement is removed from Bun description
- Verify requirement for package.json + bun.lock is documented
- Missing: Replace literal NUL with jq backslash-u0000 escape in SARIF filter
- Verify language-policy script detects Bun/Deno policy inversion
- Verify workflow script detects invalid YAML and control characters
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Missing: Replace literal NUL with jq backslash-u0000 escape in SARIF filter
Low confidence findings
- The PR description mentions external concepts like 'empty-linter enforcement'. Ensure these scripts are fully self-contained or explicitly documented if they depend on an external linter ecosystem.

🟡 MEDIUM RISK
The grep -P flag is not portable across CI environments (e.g., macOS or minimal Docker images). Since the script already checks for Python or Ruby, consider using those parsers or a portable Perl command to enforce the control character invariant.

Suggestion: Iterating over file paths using a for loop and command substitution is brittle. Use a while read loop with git ls-files -z to safely handle filenames containing spaces.

- Around line 46-48: Extend the live-text matcher in the language-policy check
around fail so it rejects equivalent TypeScript-runtime wording, including
claims that Bun supports TypeScript or that tools run .ts files, while
continuing to exclude historical quotations. Keep the existing diagnostic
reporting and prohibition message behavior unchanged.
- Around line 34-42: Update both policy checks around live and grep -qF to
consume the complete output stream instead of using early-exiting grep -q, such
as redirecting full-match grep output to /dev/null, while preserving the
existing match and fail behavior.
- Around line 52-54: Fix the awk condition in the policy-check block so finding
a matching blank first cell produces a successful status without the
unconditional END block overriding it. Update the awk program used by the
surrounding fail call, preserving the existing match criteria and reporting
behavior.
In `@tools/policy/check-workflows-parse.sh`:
- Around line 21-24: Update the no-parser fallback in check-workflows-parse.sh
to fail closed: after emitting the existing warning, exit with status 1 instead
of 0, while preserving the successful paths when yq, Python with PyYAML, or Ruby
is available.

Do not combine grep -q with pipefail here.
When the outer grep -qF finds the first match, it can close the pipe while live is still writing. With pipefail, the upstream grep can return 141, making the condition false and allowing a prohibited policy phrase through. Consume the complete stream, for example with grep -F ... >/dev/null.

Fix the awk exit status.
exit 0 still runs the END block. The unconditional END{exit 1} therefore overrides it, so this condition never succeeds. Blank first cells are never reported.

Fail closed when no YAML parser is available.
The script currently prints a warning and exits 0. CI can therefore report success without checking any workflow, which violates the gate’s exit contract. Return 1, or make one parser an explicit CI prerequisite.

## Outcome Consolidates the sound intent of #661, #682, and #683 onto current `main` without importing their stacked/conflicting history. - adds a NUL-safe language-policy invariant gate - masks quoted historical substrings instead of discarding whole lines - discovers tracked workflows before requiring a YAML parser - fails closed when workflows exist but no parser is available - uses a portable byte-level forbidden-control check - wires both gates into the reusable governance workflow - adds executable positive and negative fixtures ## Planted controls Verified locally: - quoted history: pass - quoted history plus a live violation on the same line: fail - blockquoted history: pass - blank policy cell: fail - no workflows and no parser: pass - workflow present and no parser: fail - valid workflow YAML: pass - invalid workflow YAML: fail - all 157 currently tracked Standards workflows: parse Also passed `just validate`, `just test`, `bash -n`, and `git diff --check`. Supersedes #661, #682, and #683 after merge.

fix: replace a literal NUL with the jq backslash-u0000 escape
The SARIF filter used a literal NUL byte (0x00) inside a jq string as a
field separator. Deliberate and functional - but it made this the only
first-party file that empty-linter enforcement would flag, and a raw
control byte in source is indistinguishable from corruption to a scanner.
jq interprets the backslash-u0000 escape inside its own strings, so the
emitted separator is byte-identical while the script file becomes pure
printable ASCII.
VERIFIED: jq -r with that escape between two fields emits 78 00 79.
With this and the evangeliser rewrite, empty-linter enforcement lands
green estate-wide with ZERO allowlist entries.
