They are absorbed as valid input. Our system was wounded for eleven days — and every build stayed green. This is the record of how we found it, named it, and made it impossible to hide.
Under native CSS nesting, the wound was legal syntax. No error. No failing test. Every mobile rule and every lab-page style silently stopped existing in production.
Modern tooling chose reinterpretation over rejection — and the same week, a second silent wound surfaced: 61 of 62 sitemap URLs redirected away from the pages they named.
A parser that accepts corruption as meaning turns your own system into a liar about itself.
The artifact must parse to what was written — verified in the build, not by eyeballs.
Every URL the system publishes about itself resolves directly to the surface it names.
Names and hashes stay bound under change — a chain that can drift can be forged.
