Conversation
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.
📝 WalkthroughSummary by CodeRabbit
WalkthroughThe policy now standardises Bun for JavaScript runtime and package management, moves Deno to the banned list, and adds shell gates for language-policy drift and GitHub Actions workflow parsing. ChangesPolicy and validation gates
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The new policy gate can currently report success without validating workflows or some policy files, while several format-handling paths can miss defects or reject valid copies; the CI configuration also invokes a runtime that the policy bans. These are concrete merge-readiness issues in the gate itself, so the PR should not merge until the fail-closed behavior, matcher handling, and runtime exception are corrected or explicitly accepted.

Pull Request Overview
While the PR is reported as 'up to standards' by Codacy, the implementation of the check-language-policy.sh gate contains several logic errors that will likely prevent it from functioning correctly in this environment. Specifically, the script's Markdown parsing logic (using awk and grep) does not align with the actual formatting of .claude/CLAUDE.md, which uses double-pipe (||) prefixes and specific padding.
Furthermore, all six recommended test scenarios for verifying this policy gate are missing from the PR. Given the script's complexity and its role as a CI gate, automated test fixtures are necessary to validate the various failure and success states, especially since the logic for detecting 'blanking scars' and 'recursive bans' is currently fragile.
About this PR
- The gate logic is currently too brittle to handle the estate's established Markdown style. It fails to account for double-pipe row prefixes and specific whitespace padding, which will result in false negatives or script errors when run against valid files.
- The script is labeled as 'self-tested', but there are no automated tests or test fixtures included. Given the fragility of the regex-based parsing, please include a test suite or set of example files that demonstrate the script correctly identifies the 2026-08-27 policy violations.
Test suggestions
- Missing recommended test scenario: Fail if Bun is listed as banned with Deno as replacement
- Missing recommended test scenario: Fail if tool descriptions advertise 'JS/TS runtime' or '.ts' execution
- Missing recommended test scenario: Fail if a BANNED table cell is empty (blanking scar)
- Missing recommended test scenario: Fail if a policy table exists but Bun is missing from ALLOWED
- Missing recommended test scenario: Fail if AffineScript is mapped to AffineScript in BANNED table
- Missing recommended test scenario: Pass for a compliant CLAUDE.md following the 2026-08-27 tightened ruling

🟡 MEDIUM RISK
The NF==4 condition will miss standard pipe-wrapped Markdown tables used in this repository. These tables typically result in 5 or more fields when split by | (including empty fields for the leading/trailing pipes). Consider checking for $2 ~ /^[[:space:]]*$/ without the strict NF constraint, or adjust the count to match the actual table structure.

Iterating over file paths with a word-splitting for loop is unsafe if any file path contains a space. Use a while read loop or xargs -0 to handle filenames correctly.

🟡 MEDIUM RISK
Suggestion: The regex is too strict regarding leading pipes. The document frequently uses || as a row start marker. Update the pattern to allow for an optional second pipe to ensure the gate is robust against consistent table formatting.
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

Inline comments:
In @.claude/CLAUDE.md:
- Around line 141-158: Update the language-policy job to stop installing and
invoking Deno; port the check-ts-allowlist checker and its execution to Bun, or
encode a narrowly scoped, documented CI exception if Bun cannot support it.
Ensure the job no longer runs deno run while preserving the existing allowlist
validation behavior.
In `@tools/policy/check-language-policy.sh`:
- Around line 18-19: The file-discovery logic in the policy-check script must
distinguish a successful empty result from a failed git ls-files invocation.
Capture and validate the command status before the no-files early exit,
returning failure when discovery fails while preserving the existing success
path when no CLAUDE.md files are tracked.
- Line 21: Update the fail function in check-language-policy.sh so its second
message argument is safely optional when callers such as the pattern checks
invoke fail with only one argument. Preserve the existing formatted failure
output while preventing set -u from raising an unbound-variable error.
- Around line 28-30: Update every negative check in the policy script, including
the dependency check around the Bun/Deno pattern and checks through the section
ending near lines 46–64, to scan the existing live/history-filtered content
instead of the raw file. Preserve each check’s current patterns, failure
messages, and reporting behavior while ensuring quoted or blockquoted historical
examples are ignored consistently.
- Around line 52-53: Fix the awk condition in the blanking-scar check so a
matching row returns success without the END action overriding it; ensure
non-matching files still return failure and trigger fail only when an empty
first cell is found.
- Line 34: Update the live function’s grep pattern to represent curly quote
delimiters in a grep-compatible, portable form, using literal UTF-8 characters
or an equivalent supported expression so smart-quoted text is excluded correctly
while preserving the existing straight-quote matching and blockquote filtering.
- Around line 36-41: Update both forbidden-phrase checks in the policy script to
consume the complete live output by replacing the grep -qF pipelines with
full-stream grep -F redirected to /dev/null, preserving the existing matching
phrases and fail behavior.
- Around line 28-30: Update the banned-row check in the language-policy script
to normalize Markdown table formatting before matching Bun and Deno cells,
tolerating padding, bold cell content, and repeated leading pipes. Preserve the
existing failure message and first-line reporting while ensuring inverted rows
such as a bold Bun cell are detected.
Apply the same fix in `@tools/policy/check-language-policy.sh` around lines 55 -
57: Covers the whitespace-sensitive blank-cell and Bun/Deno matcher variants.
Apply the same fix in `@tools/policy/check-language-policy.sh` around lines 63 -
64: Covers the whitespace-sensitive AffineScript self-ban matcher.
In `@tools/policy/check-workflows-parse.sh`:
- Around line 21-24: Update the no-parser fallback in the workflow validation
script to emit an error instead of a warning and exit with status 1, ensuring
the gate fails when no supported YAML parser is available.

Remove Deno from the language-policy job.
The language-policy job installs Deno and executes deno run ...check-ts-allowlist.deno.js, although .claude/CLAUDE.md bans Deno. Port the checker to Bun, or document and encode a narrow CI exception before merging.

Line [18] suppresses git errors, and Line [19] treats an empty result as success. An invocation outside a worktree or a failed git ls-files command can therefore pass the gate without checking any policy file. Check the command status before accepting an empty file list.

Normalize table rows before applying policy matchers.
The exact row and cell patterns at these checks are formatting-sensitive, so padded or double-pipe rows, bold cells, and alternate Markdown forms can either evade detection or reject valid copies. Normalize leading pipes, cell whitespace, and emphasis before checking the Bun/Deno inversion, blank **** cells, and the AffineScript self-ban. Add regression cases for the padded and pipe-wrapped forms described in the affected checks.

Use a grep-compatible representation for curly quotes.
The live function passes smart-quoted historical text to the policy checks because grep -E treats \u201c and \u201d as literal, unsupported escapes. The subsequent grep -qF then reports a false violation. Use literal UTF-8 delimiters or a portable equivalent.

Consume the complete stream before matching.
When live writes a large file, grep -qF can close the pipe after an early match. The nested grep pipeline can then return SIGPIPE; pipefail makes the outer condition false and misses the forbidden phrase. Replace both grep -qF calls with full-stream grep -F ... >/dev/null.

Fix the blanking-scar exit status.
The awk action calls exit 0, but the END action always calls exit 1. awk runs the END action after an early exit, so this condition returns 1 for every file and never calls fail. The blanking-scar gate is disabled.

Return a failure when no parser is available.
If none of the supported parsers is installed, Line [22] emits a warning and Line [23] returns status 0. The gate then reports success without reading any workflow, so invalid YAML can pass undetected. Emit an error and return status 1, or require a parser in the calling workflow.

Owner ruling on #659: keep the full text locally, but detect divergence.
Why
The language policy is duplicated into ~372 files across 131 repos. On 2026-08-26 a census 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
standardsfixes one copy of ~372; agents read the local one.Detection was the missing piece, not the copy.
Why assertions rather than a generator
The copies are legitimately not identical — repos carry their own exemption tables and carve-outs. A byte-for-byte generator would be permanently red, and a permanently-red gate gets disabled. This asserts the invariants, whatever the local wording.
What it catches
| Bun | Deno |ubicityhad no manifest and could not build under any toolchain| | X |,| **** |, "No new files"rm -rf /lib(wordpress-tools#62)| AffineScript | AffineScript |Self-tested
Because this estate has a documented history of gates that pass by not doing the work, the gate was verified before commit: a compliant file passes, and each of the five defect classes is independently caught. Controls are reproducible from the script.
