Replace the non-enforcing inline grep demonstration with a real, read-only
Empty-linter audit gate running on Bun.
What changed
compile the implemented AffineScript ByteDetector and bundle a reviewed,
checked-in Bun artefact;
add a recursive Bun CLI with separate clean (0), policy finding (1), and
scan failure (2) exits;
detect NUL, unsafe C0 controls, DEL, and the existing Unicode catalogue;
block critical controls while initially reporting ambiguous Unicode as
advisory;
plant clean, NUL, non-NUL C0, advisory, and enumeration-error probes;
migrate active runtime, tests, workflow, package, example, container metadata,
and documentation from Deno to Bun;
remove unused Deno bindings/lockfile and stop unavailable repair/settings/TUI
features from masquerading as implemented commands;
replace unsupported completion/proof claims with an evidence-bounded readiness
table.
The AffineScript compiler still names its exportable ESM target --deno-esm.
That output is an ignored build intermediate; bun build --target bun
tree-shakes the host shim, and the committed .bun.js contains no Deno
reference. A native compiler target is tracked separately.
Verification

📝 Walkthrough
Summary by CodeRabbit
New Features
Added a read-only repository audit for invisible and control characters, with severity filtering, diagnostics, and clear exit statuses.
Added detection for C0 control characters and DELETE characters.
Added Bun-based project configuration and example metadata.
Bug Fixes
CI scans now report critical findings reliably and avoid scanning excluded directories.
Documentation
Updated documentation to reflect the Bun workflow, current capabilities, limitations, and audit behaviour.
Tests
Added coverage for clean files, critical and advisory findings, malformed input, and scan failures.
Walkthrough
The project replaces the Deno-based detector and audit path with AffineScript compiled and bundled for Bun. It adds a recursive CI scanner, critical-threshold gating, Bun tests, updated toolchain recipes, and documentation of implemented and pending capabilities.
Changes
Bun audit implementation
Layer / File(s)
Summary
Detector and build artefact stdlib/ByteDetector.affine, src/core/ByteDetector.bun.js, scripts/build-all.sh, .gitignore, sonar-project.properties
The detector flags C0 controls and DELETE as critical findings. The build pipeline compiles AffineScript output and bundles the tracked Bun artefact.
Audit CLI and gate validation scripts/empty-lint-ci.js, tests/empty_lint_ci_test.js, .github/workflows/dogfood-gate.yml
The CLI scans supported files, emits diagnostics, preserves malformed-input errors, and returns distinct statuses. Tests cover clean, critical, advisory, BOM, malformed UTF-8, and enumeration-error cases. CI runs the tests and critical audit gate.
Bun toolchain and test migration Justfile, package.json, examples/web-project-bun.json, mise.toml, stapeln.toml, k9iser.toml, tests/*
Recipes, container layers, runtime constraints, example metadata, and existing tests now use Bun. Unsupported mutating commands return status 2.
Project documentation and readiness records README.adoc, TOPOLOGY.adoc, EXPLAINME.adoc
Documentation describes the audit path, exit codes, safety posture, implemented capabilities, and remaining work.
The PR replaces the non-enforcing grep with a Bun-based Empty-linter gate and migrates the surrounding tooling, but merge readiness is currently moderate because the unavailable repair path can still exit successfully and falsely signal remediation, while the checked-in generated detector has persistent static-analysis failures; the heal report also omits required tool checks and needs follow-up.

Poem
A rabbit checks each byte in line
C0 controls glow and warnings shine
Bun carries the scanner through
Clean files pass, bad files show
The build leaves one artefact bright
And hops away before midnight

Inline comments:
In `@Justfile`:
- Around line 78-91: Remove the build prerequisite from the fix, transform, and
check recipes so each command immediately reports that it is unavailable and
exits with status 2 without running build first.
- Around line 174-186: Update the heal recipe’s heading and the doctor message
describing heal so both accurately state that heal only reports missing tools
and directs users to the estate toolchain instructions, without implying
automatic installation or repair. Use the existing heal recipe and doctor
messaging symbols as the change points.
- Around line 52-59: Align the Bun test commands with the complete suite by
adding PathHandler_test.js, SafeWhitespace_test.js, and TextTransform_test.js to
both test and test-verbose in Justfile lines 52-59, and use the same complete
test command in stapeln.toml line 37.
In `@README.adoc`:
- Around line 68-69: Update the Justfile fix recipe so that after the successful
build prerequisite it explicitly exits with status 1 instead of returning
success after echoing the unavailable-operation message. Preserve the existing
refusal message and behavior for other recipes.
In `@scripts/empty-lint-ci.js`:
- Around line 161-162: Update the file-reading flow before scan in the
--all-files path to strictly validate UTF-8 bytes and reject malformed sequences
instead of allowing replacement characters through. Preserve existing BOM
detection behavior while ensuring only valid UTF-8 content is passed to scan.
In `@src/core/ByteDetector.bun.js`:
- Around line 3-11: Update the SonarCloud configuration to exclude the generated
artefact represented by ByteDetector.bun.js from the var-rule analysis, or
classify it as generated code. Do not modify the generated bindings Some, None,
Ok, Err, or the __as_* helpers.
In `@TOPOLOGY.adoc`:
- Around line 18-19: Update the read-only repository audit exit-status legend in
TOPOLOGY.adoc so status 0 states that no finding exists at the selected
threshold, rather than claiming the repository is clean; preserve the existing
labels for statuses 1 and 2.

52-64: Keep the standard Bun test recipe complete.
This repeats the previous finding. test and test-verbose still omit tests/PathHandler_test.js, tests/SafeWhitespace_test.js, and tests/TextTransform_test.js.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Make heal report the required toolchain completely.
doctor marks git, AffineScript, and Zig as required, but heal checks only Bun and just before printing Report complete. If AffineScript or Zig is missing, just heal gives an incomplete result. Add checks for the required tools, or state clearly that the recipe checks only Bun and just.
