Real-world portal catalogs duplicate one show under dozens of tagged
variants ("|ALB| Fallout", "4K-DE - The Pitt (2025) (US)",
"Breaking Bad-eng", "Fallout_esp", "The Last of Us (2023) AF"). A third
of them normalized to polluted keys, silently skipping TMDB enrichment
and staying invisible to cross-portal title matching.
normalizeTitleKeys() now handles, conservatively:
- wrapped pipe tags: "|ALB| X", "|MULTI| X"
- longer/compound leads: "EXYU| X", "4K-DE - X", "AR-SUBS - X",
"4K-OSN+ - X" (dash/pipe only; colon stays
2-3 chars so "NCIS: LA" is untouched)
- underscore suffixes: "X_eng", "(US)_msub" (single-underscore only,
"The_Last_of_Us" stays intact)
- double-dash suffixes: "X--esp"
- joined dash tags: "X-DE", "X-eng" (vocabulary-gated and
case-uniform only; "Spider-Man", "Kick-It",
"Peut-être" are untouched)
- bare trailing tags: "X (2025) DE", "Breaking Bad ES" (UPPERCASE
vocabulary only, skipped for ALL-CAPS titles;
"Rocky II", "Made in USA", "Making It" are
untouched)
Every leading-tag segment must contain a letter, so numeric titles
("1917 - ...") are never treated as tags. The display-side
stripCountryPrefix() learns the same compound/plus-sign prefixes and the
numeric guard.
buildSearchLookupKey() gets a |v2 suffix so cached negative TMDB match
resolutions keyed on old polluted titles are invalidated.
Measured on 248 real catalog names from four shows (The Pitt, Fallout,
The Last of Us, Breaking Bad): clean matching keys 65% -> 99%, display
strip 91% -> 100%. The corpora are committed as spec fixtures.
