What the reviewer found
README-writing guide whose "curl | bash" and "curl one-liner" lines describe an install section the README should have, not a command to run. The description and three body lines carry invisible U+200B/U+200C/U+200D characters that decode to the hex string fab0d3daacee, a fingerprint watermark with no instruction in it.

How this review was made
Fable 5.1 read the files above on 7 September 2026 and answered three questions: is it dangerous to whoever installs it, is each scanner finding real, and what should the installer know. The verdict is bound to the file's hash; when the file changes, it is scanned afresh and reviewed again. A script that changes while the definition does not is not re-reviewed — that is a known gap. How the scan and the review work.
