tag regex

Error message

tag regex

What it means

Compilation assertion for TAG_RE (r"<[^>]+>"), which strips HTML tags during page-to-text conversion. The expect fires only when this hardcoded literal fails to compile — a developer mistake at first use of get_tag_re, since OnceLock defers Regex::new until the first parse call.

Solutions

1. Cover get_tag_re in a unit test so an invalid literal fails in CI
2. Keep the pattern a static literal; no runtime construction path exists
3. Use regex crate syntax checks (regex_tests or a compile test) when editing the pattern
