A backtick inside a comment in a css`` literal ends the literal. It has
cost four sessions across three plans, it is written down in CLAUDE.md,
the skill and NOTES.md, and it was read twice in the session it then
cost a cycle in. Knowledge that has been ignored three times is not a
knowledge problem.
The expense is the report, not the mistake: the literal ends early, the
rest of the CSS parses as JavaScript, and tsc says 'Class static side
incorrectly extends base class static side' pointing at a line of prose
-- or, in a shared module, every test in the suite fails to import and
the output reads like a broken test runner. make dev-headless mean-
while keeps serving the last good bundle.
Detection is exact rather than heuristic: if a backtick in a comment
closed the literal early, the text the parser took as the literal
contains an unterminated /*. Nothing else produces that. Verified both
ways -- clean on the tree, and red on a deliberately broken comment.
Every <wa-icon> was fetched from ka-f.fontawesome.com at runtime —
confirmed from `performance.getEntriesByType('resource')`, 36 requests
— so offline the app had no icons at all. `setBasePath()` does not
affect the icon resolver; only the component autoloader reads it.
Overriding Web Awesome's `default` icon library fixes all 165 call
sites without changing one of them. Cross-origin requests at startup:
22 -> 0.
Three things about it are load-bearing. The set is Font Awesome Free
(CC BY 4.0, vendored with its licence by `scripts/fetch-icons.mjs`)
because the kit CDN serves Pro, which cannot be redistributed. The
names are a committed list rather than anything derived, because
twenty call sites compute their icon name from state and no static
pass can enumerate them. And a name that is not bundled is reported at
runtime to `window.__yjIconMisses` and drawn as a fallback, since a
missing icon used to be impossible — the CDN having had everything.
