Larry Arnold’s contribution / Kyle’s adaptation

Check what’s actually leaving the system.

Your strongest idea was to inspect the finished artifact. An approved source file can still produce an unsafe summary, copied code block or final page.

I brought that principle into my existing security and sharing workflow.

The check belongs after generation and before publication. It complements the decision about what a recipient is allowed to see.

Installed and verified · 3 Oct 2026

I wrote an original local implementation around that principle. It lives in Master Security Toolkit, and Work Management routes shareable publication through it. The supplied package stays preserved as review evidence; it is not a new standalone plugin or background service.

01 / The useful refinements

Keep the idea. Tighten the boundaries.

In the supplied package	In this adaptation	Practical reason
Scripts and styles are removed from the scan surface.	Scan supported text assets, including scripts, styles, comments and attributes. Check HTML entity-decoded content too.	Hidden in the interface does not mean absent from a published file.
Optional source attribution assumes a particular vault layout and reads Markdown before filtering.	Inspect only explicitly supplied artifacts or a bounded build directory. Refuse symlink traversal.	A publication check should not need access to the rest of a personal vault.
An optional flag rewrites the output with redaction markers.	Read-only findings. Correct the authoring source deliberately, regenerate and scan the new artifact.	Preserve the original and make every change reviewable.
Findings reveal some characters; an allowlist suppresses a matching value globally.	Report rule, location and fingerprint without printing the suspected value. Keep manual decisions tied to the exact artifact.	The report should not create another copy of a secret or silently approve it everywhere.
Clean output can be mistaken for permission to ship.	Separate blocking patterns, items needing review, and incomplete coverage. Keep human review of meaning and audience.	A pattern match cannot decide whether a private story or client detail is appropriate to share.

02 / Existing owners

One extra check at the right moment.

Prepare the artifactUse admitted sources and preserve the intended recipient and purpose.

Inspect the outputRun the local privacy preflight on the exact files to be shared.

Resolve & verifyFix real exposures; document review decisions and coverage limits against the artifact hash.

Publish & sendVerify the hosted page, audience and email delivery separately.

Master Security Toolkit owns the scanner and its interpretation. Work Management owns the handoff and calls the check when publishing a shareable. The existing Sites integration still owns hosting and access; the check does not change permissions or publish anything.

There is no new daemon, network service, dependency install or automatic file rewrite. The scanner cannot grant itself permission to share material.

03 / What the evidence supports

Verified behavior, with explicit limits.

The original implementation passed 25 synthetic regression tests. The tests cover recognizable credentials, scripts/styles/comments/attributes, encoded text, repeated findings, read-only behavior, symlink and vault refusal, file limits, and incomplete-scan reporting. An independent Claude static review was assessed against the code and targeted tests. Both existing plugins were installed in Codex and Claude, with file-for-file parity verified against their maintained sources.

What a clean result cannot prove

It cannot recognize every credential format, private fact or sensitive paragraph.
It does not perform OCR or inspect compressed/binary content. Unsupported files and scan limits must remain visible.
It does not decode arbitrary obfuscation, fetch remote assets or test whether a credential is live.
Local synthetic tests do not establish real-world recall, a zero false-positive rate, or a guarantee against disclosure.

Source: the supplied local-legibility-preflight ZIP, whose README and maintainer note identify Larry Arnold and date the contribution 21 September 2026. The package includes one scanner, four supporting Markdown files and two HTML fixtures. The claims about testing a separate repository at commit 2237ca69 remain the author’s reported results; that repository was not supplied or independently validated here.

04 / A note for Larry

The output-first idea was worth absorbing.

Thanks for making the concern concrete enough to inspect. The distinction between selecting approved material and checking the finished result is useful in my ecosystem, especially as I turn working notes into public shareables.

I kept that distinction and adapted the implementation to my file boundaries. My main suggestions for the original are to scan the full shipped text for recognizable credential patterns, restrict entropy heuristics separately, make source scope explicit, and add regression cases for encoded text, repeated findings and skipped content.

The best next evidence would be a small public regression corpus with both benign and sensitive-looking fixtures, expected findings, and stated blind spots. It would make future changes easier to compare without turning “clean” into a security guarantee.

One question to guide the next exchange

Which real publishing formats and failure cases should this approach handle first? HTML is a useful starting point; screenshots, PDFs and exported attachments need their own evidence and review path.
