…ies and off-site redirects A security review of the scripts and workflows found four weak spots; this closes all of them. Raw HTML and script-scheme URLs shipped in the signed database. The build rendered description/details/specs with marked and no sanitizer, so <script>, <img onerror> and [x](javascript:...) reached the *_html columns verbatim, and z.url() accepted javascript:, data: and file: for every url field because the URL parser does. pnpm validate now refuses raw HTML in prose (E305) and any scheme but http(s) on url fields and on links inside prose (E128), reading marked's own lexer so the verdict is the renderer's; the build escapes raw HTML and drops unsafe link destinations regardless, through its own Marked instance. The shared rule lives in scripts/lib/prose-markup.ts, and the generated JSON schemas carry the http(s) pattern. The corpus had no HTML and one ftp:// link (dbx 160A), which is removed. Validation and the build followed symlinks. getYamlFiles lists names and readFileSync follows a name wherever it points, so a committed data/software/x.yaml -> /dev/zero was an unbounded read in CI and in the pre-commit hook. loadYamlFile and loadYamlFileWithPositions now go through readRegularFile, which lstats first and refuses a link or a non-regular file, and the scoped --files mode puts each path through checkContainedRegularFile like validate-urls already did. url-health.yml held a contents-write token for its whole run, through pnpm install and thousands of requests to contributor-chosen URLs, and pushed to main with credentials persisted. It is now two jobs on the assign-ids pattern: a read-only check job that hands the refreshed cache on as an artifact, and a commit job that installs nothing, verifies the artifact is a version 1 cache touching nothing else, and pushes that one file. fix-urls wrote whatever a server redirected to as the entry's official url, so a lapsed maker domain bought by a squatter would have been promoted to the maker's page. A redirect that leaves the registrable domain is now reported and never written, on both the cached and the live path (the live path applied no filter at all), and the string replacement no longer reads $-patterns out of a server-chosen target.

Review comments at @.github/workflows/url-health.yml:
- Line 106: Replace the raw U+2028 and U+2029 characters in the regex literal in
the URL-validation reporting step with their escaped forms, preserving the
existing character class and replacement behavior so the actions/github-script
code compiles.
Review comments at @scripts/generate-json-schemas.ts:
- Line 70: Update the URL pattern in the generated schema to match HTTP and
HTTPS prefixes case-insensitively, keeping its existing protocol restriction so
schema validation agrees with HttpUrlSchema.
Review comments at @scripts/lib/prose-markup.ts:
- Around line 74-75: Update the recursive walk function to visit Marked table
tokens’ header and row cells so nested cell tokens are checked for E305 and
E128; add a table-cell test covering unsafe HTML and javascript links.

Three findings from review, each verified against the code: - url-health.yml carried raw U+2028 and U+2029 inside the cell encoder's regex literal, where the other workflows spell them as escapes. A regex literal cannot contain a LineTerminator, so the broken-URL report step would have failed to compile. Restored the escapes and checked that both inline scripts compile as async function bodies. - The generated JSON schemas matched the URL scheme case-sensitively while HttpUrlSchema reads the parsed, lowercased protocol, so an HTTPS:// value passed validate and failed the editor schema. The pattern now matches the scheme case-insensitively. - findProseMarkup walked `tokens` and `items` only, and marked keeps a table's cells under `header` and `rows`, so inline HTML or a javascript: link inside a GFM table cell escaped E305 and E128. The walk now visits both, with a table-cell test. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01YCFTFnEa16BWn3h15Kd6TN
