Parser behaviour spec

Derived solely from the fixtures in packages/parser/fixtures/**/*.json (about 2,930 cases), the output types in packages/parser/src/types.ts and the quality vocabulary in packages/shared/src/quality.ts. Fixtures are behavioural truth. Where a fixture only asserts “contains”, this spec says so. Section 10 lists fixtures that cannot all hold.

Conventions used below:

-> means “parses to”. s = seasons, e = episodes, abs = absoluteEpisodes.
Examples are verbatim fixture inputs. Rule numbers are stable: R<section>.<n>.
“Separator” means any of ., _, , and (context permitting) -.
Fixture quality names appear in two spellings: the shared vocabulary (WEBDL-720p) and, in series/hashed.json only, compact (WEBDL720p, HDTV720p, Bluray1080p, DVD). Both denote the same quality (see C1).

0. Output model

Field	Type	Notes
`releaseTitle`	string	input after extension stripping and website-prefix removal, original separators kept
`quality`	`{quality, revision, detectionSource}`	see section 4
`languages`	string[]	default `["Unknown"]` (section 5)
`releaseGroup`	string or null	section 6
`releaseHash`	string	8-hex CRC from `[]`/`()`; empty string when absent in anime fixtures (C7)
`series`	object or null	title, titleInfo, seasons, episodes, absoluteEpisodes, airDate, fullSeason, isPartialSeason, isMultiSeason, isSeasonExtra, isSplitEpisode, isMiniSeries, seasonPart, special, releaseVersion, subGroup
`movie`	object or null	title, titleWithoutYear, year (0 if none), edition, imdbId, tmdbId

Additional fixture-visible outputs: specialAbsoluteEpisodes (decimal recap numbers), dailyPart, isSeasonTitle, allTitles (alternative titles), languageTags, subtitleLanguage, subtitleTitle.

Media type hint: series forces series parsing, movie forces movie parsing, auto tries series structure first (season/episode/date present) and otherwise movie (title + year).

1. Input preparation

R1.1 Extension stripping. A trailing known media/NZB extension is removed from releaseTitle (.mkv .avi .mp4 .m4v .ts .nzb .xvid .divx .webm .m2ts .iso). Series.S01E02.Chained.Title.mkv -> releaseTitle Series.S01E02.Chained.Title. The extension is not part of any group: ...x264-archivist.mkv -> group archivist. A trailing .nzb and trailing _ are also stripped (scene-check: Some.Movie.2..2013...-Pate_ -> sceneTitle without _). .webm alone gives no quality (Unknown); .xvid/.divx give SDTV.

R1.2 Website prefixes. A leading [ www.Site.com ], www.Site.com -, 【... www.X.com】, or www.5MovieRulz.tc - is removed: [ www.Torrenting.com ] - Series.2012.S02E17 -> title Series 2012. Chinese pack prefix 【高清剧集网发布 www.DDHDTV.com】Series Towards You[...] is removed and does not become the group (the trailing -SeeWEB does).

R1.3 Request/tracker tags. Leading Usenet request tags are dropped: [scnzbefnet][509103] 2.Developers.Series... -> title 2 Developers Series. Trailing (S:285/L:11) seed/leech counters are ignored (quality WEBDL-1080p for ...WEB.H264-ALLDAYiN (S:285/L:11)).

R1.4 Hash tags. [8 hex] or (8 hex) near the end is releaseHash and never the group or title: [SubsPlease] Anime Title - 01 (1080p) [B1F227CF] -> hash B1F227CF. Hex containing B letters like 10B/8B still counts as a hash. Absent -> "". A bare 32/40-hex file name is a “hashed” release (R7.1).

R1.5 Separators. ., _, spaces and (inside tokens) - all separate. Output titles use single spaces: Series.With.Title.S02E15 -> Series With Title. Dots inside acronyms (R.I.P.D., The Movie from U.N.C.L.E., A.I. Artificial Movie) are kept (movies); a dot between two digits becomes a space (Evangelion 1.11 -> Evangelion 1 11), except in decimal recap numbers (R2.30). Double dots collapse (Some.Movie.2..2013).

R1.6 Brackets. Quality/format brackets ([720p], [HDTV-720p], [WEB-DL], (BD 1080p)) are metadata, never titles or groups. A bracketed year stays in series titles: Series Title [2022] [S25E13] -> Series Title [2022]; MY MOVIE (2016) [R][Action...] -> movie title MY MOVIE, year 2016. Angle brackets are stripped: <나는 솔로> -> 나는 SOLO 나는 솔로.

R1.7 Full-width / unicode normalisation. Full-width digits and punctuation are normalised before parsing: １５８ -> 158, ＆ -> &, 【720p】 -> [720p]. Accents are kept in titles (Báleygr group, Carnivàle); they are removed only in normalisation (section 8).

R1.8 Unicode titles. CJK/Cyrillic/Hangul titles are valid titles. With a Latin alternative after / or _ or in the last bracket, the Latin part wins: [哥布林杀手/Anime Series Title][12END] -> Anime Series Title; Босх: Спадок (S2E1) / Series: Legacy (S2E1) (2023) -> Series: Legacy; 我的人间烟火.Fireworks.Series.S01E01.2023.V2 -> Fireworks Series. With no Latin part the CJK title is used: [风车字幕组][名侦探柯南][857] -> 名侦探柯南; [愛戀&漫貓字幕组][10月新番][關於我轉生後成爲史萊姆那件事][18] -> 關於我轉生後成爲史萊姆那件事. Season words such as 第二季 are dropped. Mixed: [Skymoon-Raws][Anime Series 海賊王] -> Anime Series.

R1.9 Path inputs. Both \ and / separate path segments. Parsing prefers the file name; folder names fill in what the file name lacks (R7.3). Season folders: Season 3, Season 2 - Total Series Action, Specials.

R1.10 Rejection. Obvious non-releases return null series and movie: THIS SHOULD NEVER PARSE, 32/40-hex strings, random strings (R7.6).

2. Series title and numbering

2.1 Title extraction

R2.1 Title is everything before the first numbering token, separators turned to spaces. Series.Title.S01E01 -> Series Title. Empty title is valid when only a token is present: S03E09 WS PDTV XviD FUtV -> ""; Season 2\E05-06 - Episode Title HDTV-720p Proper -> "" (folder context supplies seasons only).

R2.2 Kept in the title. Years (Series.Title.2010.S02E14 -> Series Title 2010), parenthesised years (Series Title (2024), Series Title-0 (2010) keeps its hyphen), numeric-only titles (42, 69, 1234, 86 - 01 -> 86), punctuation (Developers & Coders, Series!, 24-7 Series - Title - Road to the Sonarr), hyphenated words (grp-zoos01e11 -> grp-zoo), leading numbers (2.Developers.Series -> 2 Developers Series), parenthesised alternative titles (Japanse Anime, Title (Anime, Title) retained).

R2.3 Removed from the title. Website/request prefixes (R1.2, R1.3), a leading [Group] (subGroup), quality/source/codec tokens, release group, episode titles, and leading broadcast-date prefixes in Japanese variety packs: 221208 ABC123 Series Title ep34 -> ABC123 Series Title, s1 e34.

R2.4 Bilingual titles. A / B, A AKA B, A (B) produce allTitles (R3.12-style): ["Босх: Спадок","Series: Legacy"], ["Серие","Series"]; the primary title for such releases is the Latin/last alternative. (Series J) yields an alias (see C9).

R2.5 Trailing-year mini-series wrapper. (Miniserie) (2024/S01E07/... -> Mini Title (2024). A pack wrapper (2016/S01/WEB-DL/...) -> title Seriesless (2016), season 1, fullSeason.

2.2 Single episode

R2.6 S/E forms (case-insensitive). S02E15, s02e15, S2E15, S1-E1, S15.E06, S15 E06, S01.Ep.01, S01.E.01, S01EP01, S01.Ep06, S6E02-Unwrapped. All -> season N, episode M.

R2.7 Large values are literal. S1936E18, S2009E09, S2016E231, S41 E10478, S101E01, S93E081.

R2.8 NxMM. 1x04, 4x05, 7x6, 19x06, 2009x09 (season 2009), 0x01 (season 0).

R2.9 Words. Season 01 Episode 05, Season 1 - Episode 01 -> s1 e5/e1. Dutch Se.3 afl.3 -> s3 e3. Spanish Temporada 2 [..][Cap.201] -> s2 e1; Cap.1901 -> s19 e1; Cap.408 -> s4 e8; [Cap. 101] -> s1 e1.

R2.10 Combined 3-4 digit numbers. A bare SEE/SSEE block after separators splits last two digits as episode: 103 -> s1 e3; 416 -> s4 e16; 1013 -> s10 e13; .525 -> s5 e25; 0308 (after a year) -> s3 e8. Year-like four-digit values are not split when a year context exists (Series.2010.S02E14 keeps 2010).

R2.11 Episode-only. Series Show.2016.E04, kill-roy-was-here-e07-720p, Title.E56.190121.720p-NEXT -> season 1, episode N (the 6-digit trailer is a date and ignored). E07-E08.180612 -> s1 [7,8].

R2.12 Part numbering as episode. Part01, Part 02, 5of9, Part Two -> s1 e1/e2/e5/e2. When a real SxxEyy precedes, Part is ignored: S01E01 - Part 1 -> e1; S3E3 - Part 3 Seventeen Seconds -> e3.

R2.13 Version suffix. S02E01v2, Episode 02v2, 01v3 -> episode unchanged, releaseVersion/revision.version N (R4.20).

R2.14 Split episodes. S06E01b, S01E01a -> episode 1, isSplitEpisode true.

R2.15 Decimal specials. S01E11.5 [SP] -> e11, special true.

R2.16 Numbering tokens that end the title also include #17 (e17), ep11 with Season 39 (s39 e11).

2.3 Multi-episode

R2.17 Hyphen ranges expand. S03E01-06 -> 1..6; S02E03-04-05 -> [3,4,5]; E9-E10; S01E91-E100 -> 10 values; S22E5363-E5366 -> 4; S26E96-97-98-99-100 -> 5; S04E17-28.Part.2 -> 12 episodes.

R2.18 Repeated tokens and lists. S03E01.S03E02, S07E22E23, S01e01 e02, S6E1-S6E2 -> consecutive lists. Glued E1E3 is a range: S6.E1E3 -> [1,2,3]; S6.E1E2 -> [1,2]; S6E1-E2-E3 -> [1,2,3].

R2.19 x forms. 2x04.2x05, 2x04x05, 2x9-2x10, 8x01_02, 1x01-x03, [02x01-x02], 02x01-02, 2010x15 - 2010x16.

R2.20 Implicit pairs. 103.104 -> s1 [3,4]; 10708 -> [7,8]; 10910 -> [9,10]; E.010910 -> s1 [9,10]; 101.102.

R2.21 Cap ranges. Cap.111_120 -> s1 e11-20; Ep10718 - Ep10722 -> 5 episodes. Season 01 Episode 05-06 -> [5,6].

R2.22 Dutch lists. Se.1 afl.2-3-4 -> [2,3,4]; afl.3 en 4 -> [3,4].

R2.23 “of N” is ignored. (S05E06-08 of 24), S5E6-8.of.XX, S2E1-4 of 10 -> the range only. Exception: S1E1-8 of 8 and S2E1-16 of 16 where the range spans the whole count are reported as season N with fullSeason true.

2.4 Daily / dated

R2.24 Accepted orders. yyyy-mm-dd with . - _ space; yyyymmdd; 6-digit 140722 -> 2014-07-22; mm.dd.yyyy (04.28.2014); dd-mm-yyyy (30-04-2024, 13.02.2025); yyyy.dd.mm when the middle field > 12 (2012.16.02 -> 2012-02-16; 2012.13.02 -> 02-13); 2011.12.02 -> 2011-12-02 (yyyy leading and ambiguous -> month first).

R2.25 Ambiguity rejection. A day-first/month-first date that is valid both ways is rejected: 05-06-2024, Series.Title.12.02.2025 yield no airDate. Resolved when one field > 12 (13.02.2025).

R2.26 Ordinal and word months. 5th Mar 2025, 31st Jan 2025, 23rd Feb 2024 -> airDate.

R2.27 Validity. Real calendar dates only. Future dates are accepted (2026-07-03). Very old dates (1950-10-14 in seven templated forms) are rejected; see C1 for the 1954 counterexample.

R2.28 Date versus episode token. If both appear, the SxxEyy wins when it sits right after the title: The_Series_US_s06e19_04.28.2014 -> s6 e19; Judge Developer 2016 02 25 S20E142 -> s20 e142. When the date sits right after the title and the episode token is trailing metadata the date wins: The Show Series 2015 02 09 WEBRIP s01e13 -> airDate 2015-02-09; Series and Title 20201013 Ep7432 and Series On TitleClub E76 2024 08 08 -> airDate. With two dates the first wins.

R2.29 Daily extras. Daily releases have seasons [] and episodes [] (season [0] for A.Late.Talk.Show.2010.10.11); .Part1/.Part.2 set dailyPart. A leading year-like title word stays: 2020.A.Late.Talk.Show.2012.16.02 -> title 2020 A Late Talk Show.

2.5 Anime absolute numbering

R2.30 Absolute-only. No season given -> seasons [0]… reported as episodes [], absoluteEpisodes [n]: [Group] Title - 07, _-_06_, Ep04, EP06, e66, #957, E1135, Episode 56, Episodio 13, Episode 013 VF, - 031 -, [05], {01}, (001), 01 Role Play, Turkish 69. Blm, 60.Bolum, 1. Bölüm.

R2.32 Both numberings. S10E14 214, 10x14 214, 214 10x14 -> s10 e14 abs 214. Title S01E01.001 -> abs 1. Series Title (2014) - 017 (115) -> abs 17 (first number). (Season 2) - 33 -> s2 abs 33. S01 - 05 - S01E05 -> s1 e5 abs 5.

R2.33 Absolute ranges. 26-27, 01-12, (01-25), 1-13, Ep01-12, 091-123, 01 - 119, 01~10, 01 ~ 10, [01-05], (892-916), 1017-1088, S01 - 01-12 (title Title S01). CJK: [88-91], [01-24完].

R2.34 Episode markers in CJK. [12END], [13完], [215 END], [215 Fin], [第05话], [857集], [第1008話] -> number only. [第01-15集] in a pack -> season 1 episodes 1-15.

R2.35 Specials/OVA. - 01 - Special/OVA/OVD -> special true abs 1. OVA - The Other, NCOP, NCED -> special true, abs [], seasons [0].

R2.36 Anime season pack. S01 [Web]..., S01 12 13, S1 05, (Season 1), [Season 1 + EXTRA] -> season 1, fullSeason true, abs [].

R2.38 Batch path. Series Title 921-928 [..]/921.mkv -> abs [921] (file name wins).

R2.39 Season-less batch title (isSeasonTitle). [Group] Series Title Curse (BS11 1280x720 x264 AAC) -> title Series Title Curse, fullSeason true, isSeasonTitle true, seasons []. Dots retained in this mode (Series.Title - Curse). Rejected when stripping leaves only metadata, for extras (OVA, Special, NCOP, NCED), and when any normal regex parses (S02E05, - 05, S02).

R2.40 SubGroup. The leading bracket is subGroup and releaseGroup: [GHOST][1080p] Series - 25 -> GHOST. Anime-Series Title S04 - 12 -> title Anime-Series Title S4 (see C5).

2.6 Seasons: full, multi, part, extras

R2.41 Full season. S04, Season 4, Season4, S 01, S2014, Saison3, SAISON.1, Stagione.3, Temporada 10, Sezon 3, [Season 3], (S03), (Season 1), Series 1 (1970) -> fullSeason true, one season, episodes []. Title keeps a year (Series 2021 S04) and numeric tails like 00/100.

R2.42 Bare season folders reject. Input exactly Season 3 is a folder, not a release. Series.of.Sonarr.S03.720p.BluRay-CLUE\REWARD keeps title Series of Sonarr.

R2.43 Multi-season. S01-05, S01-S09, S01 - S07, Season 01-07, Season 01 - Season 07, S01 S04, S01 04 -> inclusive range; S01 S02 S03 S04 -> list; S01 S03 S04 -> [1,3,4] (three or more tokens are an explicit list, two tokens are a range: Series Title S01 S04 -> [1,2,3,4]). Flags: fullSeason true, isPartialSeason false, isMultiSeason true.

R2.44 Season part. S02.Part.1, S07.Vol.1, S06.P1, S03 - Vol.02, S03 Part 2 -> isPartialSeason true, seasonPart N, fullSeason false.

R2.45 Season extras. S05 EXTRAS, S03.Extras.01.Deleted.Scenes, SUBPACK -> fullSeason true, isSeasonExtra true.

R2.46 [Group] Title 2 S01 -> title Series Title 2, season 1 (number before season token stays in title).

2.7 Mini-series, specials, season 0

R2.47 Mini-series. Part 2 style with no season -> season 1 episode 2, isMiniSeries true.

R2.48 Special detection (isPossibleSpecialEpisode). True for S02.Special-Inside..., S05.Special, S11E00.A.Christmas.Carol.Special; false when the word sits in the title: Big.Special.Show.S05. Season 0 in S00E16, 0x01, folder Specials.

2.8 SeriesTitleInfo (title-info.json)

R2.49 Year split. title includes the year, titleWithoutYear removes it, year is the number (0 when none). Series.2022.S03E14, Series (2022), Series_2022_ -> titleWithoutYear Series, year 2022; Series Title 2004 -> Series Title. No year -> title == titleWithoutYear, year 0.

R2.50 Numeric titles. 1234 2022 -> titleWithoutYear 1234, year 2022; 1234 S03E14 -> year 0 (the number is the title).

R2.51 Country. country is a trailing country/variant tag (US, UK, AU) or null. No fixture in title-info.json exercises a country value; implementers must output null when absent and may recognise only those suffixes.

3. Movies

R3.1 Title, year. Title is everything before the year (or before release metadata). 1776.1979 -> 1776, 1979; 8.2019 -> 8; Cars.2.German.DL -> Cars 2, year 0.

R3.2 Several years. The year is the last plausible year before release info: Klasse von 1999.1990 -> title Klasse von 1999, year 1990; Rokudenashi Blues 1993 (1993) keeps 1993 in title, year 1993; A Fake Movie 2035 2012 Directors keeps 2035 in title, year 2012. A parenthesised or bracketed year wins: World Movie Z Movie [2023] -> 2023; Movie Name (1897) [DVD].mp4 -> 1897.

R3.3 Leading parenthesised tokens. (500).Days.Of.Movie.(2009) -> (500) Days Of Movie; (1995) Movie Name -> Movie Name.

R3.4 Subtitle after colon kept. Movie: The Movie World 2013. Roman numerals remain in titles; 1-20 map I..XX both ways (roman-numerals.json).

R3.5 Trailing junk dropped. Bracketed tags after the year, German, TRUEFRENCH, DL, Dubbed and corrupt characters after the year are cut: Mission Movie: Rogue Movie (2015)\uFFFD[XviD... -> title ends at the year.

R3.6 Anime movie. [MTBB] Kimi no Na wa. (2016) v2 -> title Kimi no Na wa (trailing dot removed), group MTBB, year 2016, version 2. No year: Evangelion 1.11 - You Are (Not) Alone v2 -> Evangelion 1 11 - You Are (Not) Alone.

R3.7 Version. 2018v2, 2018 v2 -> version 2; default 1 (anime-version.json for movies).

3.1 Editions (edition.json)

R3.8 Output preserves input casing and word spelling. Vocabulary: Directors Cut, Director's Cut, Directors, Despecialized, Special Edition, Special Edition Remastered, Special Edition Fan Edit, Extended, EXTENDED, Extended Cut, EXTENDED CUT, RECUT EXTENDED, EXTENDED EDITION, Extended Directors Cut Fan Edit, Extended Directors Cut FanEdit, Extended Theatrical Version IMAX, 50th Anniversary Edition, 2in1, IMAX, Restored, Final Cut, Assembly Cut, Ultimate Hunter Edition, Diamond Edition, Ultimate Rekall Edition, Signature Edition, Open Matte, Imperial Edition (leading The dropped from the output).

R3.9 Position. The edition can precede or follow the year and is removed from the title (Movie.Title.Imax.2018 -> title Movie Title, edition Imax; Movie.1987.Ultimate.Hunter.Edition -> edition after the year).

R3.10 Not editions (edition null). Title words (Holiday.Special), an edition at the very start (Directors.Cut.German.2006), Uncut.Movie, The.Christmas.Edition.1941, source tags like TS (Loving.Movie.2018.TS.FRENCH), Movie Impossible: Rogue Movie 2012 Bluray.

3.2 IDs

R3.11 External ids. {tmdbid-43074}, [tmdb-43074], {tmdb-43074}, {tmdb-2020} (4-digit id is not a year) -> tmdbId number. [tt1234567], [tt12345678] -> imdbId (7 or 8 digits). Ids are stripped from the title.

R3.12 normalizeImdbId. asfd -> null; 123 -> tt0000123 (pad to 7); 1234567 -> tt1234567; tt1234567 unchanged; tt12345678 and 12345678 -> tt12345678.

3.3 Hardcoded subs, alternatives, language words

R3.13 Hardcoded subs. KORSUB -> KORSUB; KORSUBS -> KORSUBS; HC, SUBBED -> Generic Hardcoded Subs. Not hardcoded (null): RoSubbed, Softsubs, Softsubs(HorribleSubs), MultiSubs.

R3.14 Alternative titles. Split on AKA, aka, a.k.a., A.K.A., (aka X), / (including Cyrillic Енола Голмс / Enola Holmes). Result list: the full string first, then each trimmed part; the full string keeps internal double spaces (Radarr prodavet AKA Radarr Shift), A.K.A. is normalised to AKA in the full title. AKA.2002 -> ["AKA"]; Aka Rox (2008) -> ["Aka Rox"] (title word, no split).

R3.15 Language words in titles stay. The.Good.German, The.German.Doctor, German.Lancers, The.Irishman, The.French.Movie, The.Italian.Movie, Spanish Killroy was Here, The Danish Movie 2015, The.German.2019: they remain in the title and add no language (languages ["Unknown"]).

R3.16 Website prefixes (www.Torrenting.com, www.5MovieRulz.tc) removed (R1.2).

Resolution tags: 360p/480p/480i/540p -> 480 (360 and 540 round to 480, 848x480 and 640x480 too); 576p -> 576; 720p, 960p, 1280x720, HD -> 720; 1080p/i, 1920x1080, FHD, 1440p -> 1080; 2160p, 4K, UHD, UltraHD, 3840x2160 -> 2160.

Examples: Movie.Name.S04E10.480p.WEB-DL.x264-mSD -> WEBDL-480p; Movie.Title.2013.960p.WEB-DL.AAC2.0.H.264-squalor -> WEBDL-720p; Movie Name.S02E04.1440p family -> 1080; Movie Name 2020 WEB-DL 4K H265 10bit HDR DDP5.1 Atmos-PTerWEB -> WEBDL-2160p; Movie.Title.2014.2160p.BDRip.AAC.7.1.HDR10.x265.10bit-Markll -> Bluray-2160p; Movie.Title.2018.Bluray720p -> Bluray-720p.

4.2 Resolution/source inference

R4.1 Source and resolution given -> use both.

R4.2 Source only. HDTV/WEB/Bluray with no resolution tag: television -> 720 (bare HDTV) except SD cues -> 480. Observed: HDTV ([HDTV], HD TV) -> HDTV-720p; Movie.Name.S04E05.HDTV.XviD-LOL -> SDTV (xvid cue); WEB-DL in brackets with no res -> WEBDL-720p; WEBMux without res -> WEBRip-480p; Movie.Title.S01E01.Bluray -> Bluray-720p (disc without res, not remux); BDRip XviD -> Bluray-480p; German AmazonSD / AmazonHD.x264 DL without res -> WEBDL-480p.

R4.3 Resolution only. 720p alone -> HDTV-720p; 1080p alone -> HDTV-1080p; 848x480 -> SDTV; 2160p alone -> HDTV-2160p; [480p] -> SDTV.

R4.4 Codec hints. x264-CtrlSD -> SDTV; H265/H266/HEVC without res on a WEB source -> WEBDL-1080p; Hi10P 1280x720 -> HDTV-720p.

R4.5 PDTV exception. HR.WS.PDTV (high-res widescreen) -> HDTV-720p; WS.PDTV.x264 without HR -> SDTV.

R4.6 Remux without 1080/2160 tag. 720p ... REMUX and 480i ... REMUX stay at their own source resolution (Bluray-720p/480p); Movie.Hunter.2018.720p.Blu-ray.Remux -> Bluray-720p.

R4.7 UHD disc rules. UHD BluRay + 1080p -> Bluray-1080p; UHD BluRay + 2160p -> Bluray-2160p; 4K.BluRay.Remux.1080p -> Remux-1080p (the explicit resolution tag beats 4K). Remux with 2160p -> Remux-2160p.

R4.8 Remux by Hybrid-REMUX/German ML tag. 1080p BluRay Hybrid-REMUX AVC TRUEHD -> Remux-1080p; German.ML.1080p.BluRay.AVC -> Remux-1080p.

R4.9 BR-DISK precedence. BDISO/ISO/COMPLETE/BD25-66 and bluray with AVC/VC-1/MPEG-2 disc audio (DTS-HD MA, TrueHD, LPCM) and no x264/x265 encode token -> BR-DISK even when a 2160p tag is present (UHD Blu-ray DTS-HD MA 5.1 DV HDR HEVC-UNTOUCHED -> BR-DISK, resolution 1080 in the vocabulary).

R4.10 Telecine/telesync resolution is 0 in the vocabulary regardless of any 720p tag.

R4.11 Case. Bluray.2160p-glued forms (Bluray720p, BD720p, [BD1080p], 720p-AAC) parse.

R4.12 Disc-less BD. [FFF] Movie - 01 [BD][720p-AAC] -> Bluray-720p; [Elysium]Movie.Name.01(BD.720p.AAC.DA) -> Bluray-720p.

R4.13 Anime web. [HorribleSubs] ... [Web][MKV][h264][480p/720p/1080p/2160p] -> WEBDL-xxx; no resolution -> WEBDL-720p; [SubsPlease] Movie Title (540p) and [Erai-raws] ... [540p] -> WEBDL-480p.

R4.14 Enum-style names. [Bluray-1080p Remux] -> Remux-1080p; My series S01E01 1080p-HD-TV -> HDTV-1080p; 720p-WEB-DL -> WEBDL-720p; 1080p-Remux -> Remux-1080p; SD-DVD -> DVD; 480p-WEB-DL -> WEBDL-480p.

R4.15 Unknown. No cue at all (Some.Movie.S02E15, Movie Name - 11x11 - Quickie, S01E01.webm, The.Web.MT-dd) -> Unknown (id 0), revision default. WEB as a bare word of the title (The.Web) is not a source.

4.3 Detection source

R4.16 detectionSource is name when source or resolution came from the name, extension when only the container extension decided (.mkv, .avi), unknown otherwise. Fixture fields are per-axis:

Input	source detection	resolution detection
`Movie - 2018 [HDTV-1080p]`, `Bluray1080p`, `1920x1080.Bluray`	name	name
`Movie.Title.2018.848x480` (resolution only)	unknown	name
`Movie.Title.S01E01.Bluray`, `HD.TV`, `SD.TV`, `...PDTV-REPACK-TLA` (source only)	name	unknown
`Movie.Title.S01E02.Chained.Heat.mkv`, `...avi`, `[CR] Movie Title - 004 [48CE2D0F].avi`	extension	extension
`Movie.Name.S01E02.Chained.Heat.1080p.mkv`, `...720p.avi`	extension	name

R4.17 Extension fallback. .mkv -> HDTV-720p; .avi/.xvid/.divx -> SDTV; .m2ts -> Bluray-720p (S03E01.The Electric Can Opener Fluctuation.m2ts). .ts alone is not telesync (SomeMovie.2018.DVDRip.ts -> DVD).

4.4 Revision

R4.18 Version. Default 1. PROPER -> version 2, isRepack false. REPACK, RERIP -> version 2, isRepack true. REPACK2, RERIP2 -> version 3. Case-insensitive; a trailing -RP group suffix after PROPER keeps version 2 (PROPER.HDTV.x264-RiVER-RP).

R4.19 Real. real counts occurrences of an upper-case REAL token that is not part of the title: REAL.REAL.PROPER -> real 2; REAL.PROPER -> 1; PROPER.REAL.RERIP -> real 1, version 2. Lower or mixed case does not count: real.proper -> 0; Real.Proper -> 0; the title words The Real Housewives of Some Place -> 0. Version is still 2 for these PROPER cases.

R4.20 Anime version. v2 glued (01v3, Episode 02v2, S01E01v2) or spaced (01 v2, S01E01 v2) or bracketed ([v2], WEBDL-1080p v2) -> version N; no v-tag -> 1. [DeadFish] Series Title - 01v4 -> 4.

R4.21 UltraHD. UltraHD, Ultra HD, UHD, 4K all imply 2160 when paired with a 2160p tag; Into the Movie 2016 2160p Netflix WEBRip -> WEBRip-2160p.

R4.22 Name -> quality id. The final quality name is looked up in the shared vocabulary: HDTV-720p=4, WEBDL-720p=5, Bluray-720p=6, WEBDL-1080p=3, Bluray-1080p=7, HDTV-1080p=9, Raw-HD=10, Remux-1080p=20, Remux-2160p=29, BR-DISK=30, DVD-R=22, DVDSCR=23, WORKPRINT=24, CAM=25, TELESYNC=26, TELECINE=27, REGIONAL=28, SDTV=1, DVD=2 (see packages/shared/src/quality.ts).

5. Languages

R5.3 Multiple languages. All distinct matches are reported in order of appearance: Eng Fra, FR ENG -> French+English in either order (asserted as contains); [Hindi 5.1 + English 5.1] -> [Hindi, English] exact; Eng Fre Ger Ita Por Spa -> [English, French, German, Italian, Portuguese, Spanish] exact; Ukr/Eng -> Ukrainian+English; 2Ukr/Tur -> Ukrainian+Turkish; RU-KA -> Russian+Georgian; esp cat, SPA-CAT, Castellano - Catalán -> Spanish+Catalan; Esp.DD2.0,Ing.DD2.0,Cat.DD2.0 -> [English, Spanish, Catalan] as an exact set.

R5.4 German DL/ML. German.DL -> ["German","Original"] exact; ML -> ["German","Original","English"]; Original/Orig alone -> ["Original"]. WEB-DL / WEB.DL / WEBDL / WEB DL do NOT add Original.

R5.5 Subtitle-only tags are not audio. SUBFRENCH, Eng-Subs, PL-SUB, PLSUB, SUB-PL, and .en.sub file names -> Unknown for the release language. Catala.Spanish.Subs still lists Catalan (contains).

R5.6 Title words excluded. Only tokens after the title/year region are languages; see R3.15. Language words inside the release group are excluded: x264-SKGTV English -> group SKGTV (and languages English).

R5.7 Case policy. Two-letter codes (EN, FR, ES, DE, RU, PL, LT, CZ, SK, KA) are matched upper-case only, except lv (also lower) per fixtures (C3).

R5.8 Portuguese variants. Portuguese full name -> Portuguese; Brazilian, Dublado, pt-BR -> Portuguese (Brazil); in the ISO table pt, por, pt-PT -> Portuguese; de-AU -> null.

R5.9 Spanish Latino. Latino variants -> Spanish (Latino) (Radarr asserts firstLanguage Spanish (Latino)).

R5.10 ISO 639-1/2 codes and lang-REGION forms resolve: en, eng, en-US, en-GB -> English; pt, por, pt-PT -> Portuguese; cze (alternate code) -> Czech; ur, urd, ur-PK -> Urdu; rm, roh, rm-CH -> Romansh; ka, geo, kat, ka-GE -> Georgian; ga, gle, ga-IE -> Irish. Null: enus, enusa, wo, fr-CA, de-AU.

5.2 Subtitle file names

R5.11 A language token before the extension sets subtitleLanguage (en, EN, eng, ENG, English -> English); none -> Unknown. Tags default, forced, cc, sdh go to languageTags; order [default, forced] when both precede the language and [forced] when after. Remaining free text is subtitleTitle (testtitle, Full Subtitles, mytitle - 1 -> mytitle/mytitle 1, ru-something-else -> Russian + something-else). Only tags / nothing -> language Unknown and subtitleRawTitle null.

6. Release group

R6.1 Scene suffix. The group is the text after the last - of the release: .XviD-LOL -> LOL. Space-separated groups are not suffix groups: x264 LOL -> null.

R6.2 Hyphenated groups kept whole from a known list or when a hyphen is inside a group: D-Z0N3, Fight-BB, Erai-raws, Blu-bits, DX-TV, FTW-HS, VH-PROD, Báleygr, Hveðrungr, -ZR- -> ZR.

R6.3 Bracket trailing group. [RlsGroup], [rl], [TAoE], [HDO], [QxR], [UTR], [SEV] at the end. A trailing bracket group beats an earlier hyphenated token (...-Goki[TAoE] -> TAoE). Spaced bracket names ([Data Lass]) are null while -DataLass -> DataLass (C13).

R6.4 Anime leading group. The first [Group] of an anime release: FFF, HorribleSubs, Anime-Koi, Erai-raws, Tenrai-Sensei, Exiled-Destiny, Anime Time, Project Angel, Hakata Ramen, GHOST, MTBB, OPFans (from [OPFans楓雪動漫]), 喵萌奶茶屋, 傲娇零&自由字幕组.

R6.5 Known exception groups (glued or spaced to the codec tag). Recognised by name even without a hyphen: Tigole, afm72, Silence, Panda, Ghost, MONOLITH, Kappa, Natty, RCVR, SAMPA, YOGI, r00t, EDGE2020, E.N.D, KRaLiMaRKo, BluDragon, DarQ, KCRT, BEN THE MEN/BEN.THE.MEN, Vialle, Celdra, HONE, GiLG, LMain, Eml HDTeam/EML HDTeam, YIFY, YTS, YTS.MX, YTS.LT, YTS.AG, TMd, Qman, theincognito, Joy, Vyndros, Bandi, Kametsu, CtrlHD, DHD, DusIctv, SEV, ADC, Koten_Gars, RH, XZVN, HQMUX, ZØNEHD, FreetheFish, 126811, Garshasp, t3nzin, ImE, Goki. A suffix that merely glues extra text onto them is null: t3nzinFAKE, VialleFAKE. Movie.Should.Not.Use.Dots.2022.1080p.BluRay.x265.10bit.Tigole -> null while the same with a trailing ) -> Tigole.

R6.6 Strip bad suffixes after the group. A GROUP-SUFFIX where the suffix is one of: RP, RP-RP, Obfuscated, Obfuscation, Scrambled, NZBgeek, 1, 4P, 4Planet, postbot, xpost, Rakuv, Rakuv02, Rakuvfinhel, RakuvUS-Obfuscated, WhiteRev, BUYMORE, AsRequested, AlternativeToRequested, GEROV, Z0iDS3N, Chamele0n, AlteZachen, RePACKPOST, sample, Pre returns GROUP: MeGusta-Pre -> MeGusta. [N-Z-B]-xpost after .mkv is ignored.

R6.7 Language word after the group is stripped: x264-SKGTV English, _English, .English -> SKGTV.

R6.8 Not groups. Anime hash (iKaos [v3] [6AFFEF6B] -> null); episode titles in brackets (Hart-Shaped Murder [SDTV][AAC 2.0][x264] -> null); quality brackets ([HDTV-720p]); audio/video tokens (REMUX.AVC.DTS-MA.5.1, WEB-Rip.DDP.5.1.HEVC, DTS-X.MA, DTS-ES); 7s-Series-s02e01-720p.mkv -> null; Subs] with no group.

R6.9 Extras. S05 EXTRAS DVDRip XviD RUNNER -> null (space) but S01.EXTRAS.DVDRip.XviD-RUNNER -> RUNNER.

R6.10 Extension excluded (R1.1).

7. Hashed releases, paths, crap

R7.1 Hashed file name. When the file name is a 32/40-hex hash, gibberish or otherwise non-release, title/quality/group come from the folder: C:\Test\Some.Hashed.Release.S01E01.720p.WEB-DL...-Mercury\0e895c37...mkv -> title Some Hashed Release, WEBDL-720p, group Mercury. A hash-like folder defers to the file name (movies hashed.json). Series uses compact quality names; movies hyphenated (C8). Folder without group -> group null.

R7.2 Reversed names. A reversed file name is detected and un-reversed: yrucreM-462.H.0.2CAA.LD-BEW.p027.10E10S.esaeleR.dehsaH.emoS.mkv -> Some Hashed Release, WEBDL-720p, Mercury; ...P0801... -> WEBDL-1080p; 50E50S.denorD.mkv -> Droned, HDTV-720p, group null; 010E70S.nuF.fo.snoS -> Sons of Fun; 11E-20S seires.mkv -> series.

R7.3 Path fallback (path.json). Season from folder, episode from file when the file lacks them: z:\tv shows\series title (2003)\Season 3\S03E05 - Title.mkv -> s3 e5; z:\tv shows\series title\Specials\S00E16 - Dear Title - SD TV.avi -> s0 e16; C:\Test\Series\Season 01\01 Pilot (1080p HD).mkv and 1 Pilot -> s1 e1; Season 1\02 Honor Thy Father -> e2; Season 2\01. Total Series Action - Episode 1 - Monster Cash.mkv -> s2 e1; Season 1\02.04.24 - S01E01 - The Rabbit Hole -> e1 (the date-looking prefix is ignored); 8 Series Rules - S01E01 - Pilot -> e1; S:\TV Drop\Series - 10x11 - Title [SDTV]\1011 - Title.avi -> s10 e11 (also forward slashes); Series Title S02 01.mkv, S2 1.mkv, S2 10.mkv, S02 01.mkv -> s2 e1/e1/e10/e1; C:\Test\Series Title S01 02\Series Title S02 01 1080p WEB-DL.mkv -> s2 e1 (file beats folder); E:\Downloads\tv\Series.Title.S01E01.720p.HDTV\ajifajjjeaeaeqwer_eppj.avi and ...\tbbt101.avi -> s1 e1 (folder); C:/Test/TV/Series.4x05.HDTV.XviD-LOL -> s4 e5. fullSeason false for all path fixtures. Multi: 01-03\The Series Title (2010) - 1x01-02-03 - Episode Title HDTV-720p Proper -> title The Series Title (2010), s1 [1,2,3]; Season 2\E05-06 - Episode Title HDTV-720p Proper -> title "", s2 [5,6].

R7.4 Scene check. isSceneTitle (movies) needs title + year + quality + group: Some.Movie.2..2013.German.DTS.DL.720p.BluRay.x264-Pate true; missing any of quality, group, title or a hash-only name -> false. Series scene check needs title + SxxEyy (or Sxx) + quality + -GROUP; S08E05 - Virtual In-Stanity [WEBDL-720p] false. sceneTitle strips trailing _, .mkv, .nzb and converts 【720p】 to [720p].

R7.5 Slug. Strip accents, lowercase, spaces to dashes; specials removed (default) or dashed when replaceSpecialCharsWithDash is true; trimChars default -_ trims the ends; deduplicateChars default -_ collapses runs; null options use defaults. test-_--_result -> test-result, test-_-_result -> test_result; ß, œ, Ø are stripped.

R7.6 Crap rejection. Return null series and null movie for: 32/40-hex or other hash-only names, random alphanumerics, thebiggestmovie1618finale, Big Movie (S01E18) Complete 360p HDTV AAC H.264-NEXT (movie mode only), THIS SHOULD NEVER PARSE, password - ... yEnc, and series crap such as Sonar TV - Series Title : 02 Road From Code [S04].mp4 is noThrow: the parser must not throw on any input.

8. Normalization

8.1 normalizeTitle (series and movies)

Transformations, applied in order:

Lowercase.
Remove accents/diacritics: Carnivàle -> carnivale, Ríkið -> rikid (ð -> d), Parler à -> parlera.
NN% after a digit becomes NNpercent: 3% -> 3percent, 100% -> 100percent.
Drop & and ': I'm a cyborg, but that's OK -> imcyborgbutthatsok.
Remove the standalone words the, and, or, a, an, of when they are separated words in the middle (not first or last), separators ., -, , _: Law_and_Order_SVU -> lawordersvu; Series_and_Title_Sonarr -> seriestitlesonarr; Series of the Day -> seriesday; Series of the Day 2 -> seriesday2. Leading/trailing words stay: The Office -> theoffice; Tokyo Ghoul A -> tokyoghoula; Series Title A -> seriestitlea; word.theword unchanged.
Remove every remaining non-alphanumeric character: Castle (2009) -> castle2009; Series - 4x05 -> seriestitle (as parse_series_name); The Series Bros. (2006) -> theseriesbros2006; The Daily Series - -> thedailyseries; Mad Series - Season 1 [Bluray720p] -> madseries.
Movie variant: the lone-letter article a adjacent to single-letter tokens is kept: word.a.N.K.L.E.word -> wordankleword; word N K L E a word -> wordnkleaword.

8.2 cleanTitle

cleanTitle is the series/movie normalizeTitle result stored for matching. The parse_series_name fixtures assert cleanTitle: Bad Format -> badformat; Series & Title -> seriestitle.

8.3 Roman numerals

I..XX (1-20) convert both ways; used when comparing movie sequel titles (roman-numerals.json).

9. Output casing and shape summary

Titles keep original casing; only separators and metadata change.
Missing values: strings "" for empty series title, hash ""; nullable fields use null per types.ts.
year 0 means none. isMultiSeason only for season ranges/lists. fullSeason true for season packs and for Sxx packs, season extras, anime season packs.
Order of arrays: ascending numeric for expanded ranges; appearance order for explicit lists and languages.

10. Known contradictions in fixtures

C1. Old daily dates. 1950-10-14 is rejected in seven {year} {month} {day} template cases, yet Series Title (1955) - 1954-01-23 05 00 00 - Cottage for Sale.ts is accepted with airDate 1954-01-23. A threshold between 1950 and 1954 resolves it; a title-year-sensitive rule would too. Spec: accept dates from 1951 onward (unverifiable).

C2. Ambiguous dates. 05-06-2024 and 12.02.2025 are rejected as ambiguous, while 2011.12.02 is accepted and 13.02.2025 is accepted. Consistent only if year-first dates default to month-first and day-first/month-first forms are rejected when both fields <= 12.

C3. Language case policy. Movie Title 1994 EN 1080p -> English but Movie.Title.2010.En.1080p -> Unknown; both lv and LV -> Latvian. Case sensitivity is not uniform.

C4. Anime season packs vs absolute. [Group] Title S01 - 01-12 -> title Title S01 with absolute 1-12, while [Group] Title S01 12 13 and [Group] Title S1 05 -> season 1, fullSeason true, no episodes. Distinguishable only by dash presence.

C5. Season token in anime titles. Anime-Series Title S04 - 12 -> title Anime-Series Title S4 (leading zero removed), but Series Title S03 - EP14 -> Series Title S03 and Title S01 - 01-12 -> Title S01 (zero kept).

C6. misc.json Series.911.S01. normalized series911 but seriesName series 911; every other row has seriesName equal to the normalized form.

C7. Release hash null vs empty. types.ts declares string | null; anime fixtures expect "" when absent.

C8. Quality name spelling. series/hashed.json expects WEBDL720p, HDTV720p, Bluray1080p, DVD; movies/hashed.json and the shared vocabulary use WEBDL-720p, Bluray-1080p. Both cannot be the canonical output string; compare by id or normalise.

C9. Parenthesised alternative titles. [Judas] Series E (Series J) -> allTitles ["Series E","Series J"], but Japanse Anime, Title (Anime, Title) keeps the parentheses in the single title.

C10. Special word. S02.Special is a possible special but Big.Special.Show.S05 is not; only title position separates them.

C11. Remux vs 4K tag. Movie.Title.II.2003.4K.BluRay.Remux.1080p -> Remux-1080p while Movie Title 1976 2160p UHD Blu-ray DTS-HD MA 5.1 DV HDR HEVC-UNTOUCHED -> BR-DISK with resolution 1080 despite a 2160p tag; and German.ML.2160p.BluRay.HEVC -> Remux-2160p. Resolution is not always the named one.

C12. TS tag. Loving.Movie.2018.TS.FRENCH has edition null and quality TELESYNC, while SomeMovie.2018.DVDRip.ts (extension) is DVD.

C13. Spaced bracket groups. [Data Lass] -> null but [TAoE], [QxR], [HDO] accepted; the difference is a known-group list or the space only.

C14. Series.of.Sonarr backslash. Series.of.Sonarr.S03.720p.BluRay-CLUE\REWARD contains a path separator in a name fixture; parse as release name, title Series of Sonarr, group not asserted.

C15. Duplicate fixtures. Series.Stagione.3.HDTV.XviD-NOTAG and [HorribleSubs]_Show_Title_-_33_[720p] appear twice; harmless.
