A leading 2-5 character uppercase token before a dash, pipe or colon was always read as a provider tag, so a film whose NAME is such a token lost it and normalized down to its release year alone. "AKA - 2023" became the key "2023", where it collided with BDE, BRO, OUT, WIL and IF — and they were offered to each other as alternative sources in VOD multi-source. "IT - 65 (2023)" (the Italian copy of the film "65") is structurally identical, so only the token's meaning can separate them. The leading token is now tested against a vocabulary — TRAILING_TAG_VOCABULARY plus a prefix-only list derived from the real catalog — but only when the strip would leave no real word behind. A compound is read by its head, so the open-ended "4K-<lang>" family keeps working while "INU-OH" and "PC-4L" are recognized as film names. An unknown token keeps its title: a refused strip costs one unmatched copy, a wrong one corrupts that film's identity in VOD multi-source, the TMDB Similar rail, DB_MATCH_TITLES and pin keys. "No real word" is decided by running the rest of the pipeline on the stripped form and looking at what comes out, never by re-implementing what later stages remove. Quality tags, trailing and underscore tags, double-dash suffixes and season markers each otherwise smuggle the strip through, and a stage added later is covered for free. Validated over the live catalog, movies and series: 83 keys fixed, 0 corrupted across 1,616,111 titles. Deriving the vocabulary from movies alone missed AMZ, D+ and P+ and broke the Paramount+/Disney+ copies of the numeric series 1923, 1883, 24 and 9-1-1.
