Keyed on the whole episode title, every episode of a box set became a group of one and never reached the five-episode size that calls something a series, so the live run filed 124 Monk episodes as 124 movie folders, each named after its own episode. ep_of now returns the series — the name before SxxEyy / 1x04 / Part N — and the planner groups and names the quarantine pile by that series, so one show is one pile: 'Monk - S05E03 - Mr. Monk and the Big Game' is series monk. The threshold keeps its job: a lone film named Part 2 stays a film. Re-planning the live census with this moves nothing differently except the 124 Monk files, which now join the TV pile: 168 episode files across 3 series.

r"""The fleet's release-filename title parser: the grouping authority the relayout

what title_of() makes of a name — the way to check a naming accident
|

before it merges two films into one folder.
|
||
|
||
scripts/media-plan.py imports this file; over there the paths are arguments.
|
||
|
||
Method — three independent signals, so a naming accident cannot merge two films:
|
||
* franchise KEY : first two significant title tokens. Stable across parts of a
|
||
collection ("resident evil", "jump street") but NOT film-specific — it only
|
||
selects candidates.
|
||
* DURATION : the identity check. Same master encodes differ by at most a
|
||
couple of seconds; different films / cuts do not collide.
|
||
* SIZE SPREAD + YEAR: decide the tier. Two files same size AND same duration
|
||
are byte-twins (the hash pass confirms); same duration but different sizes are
|
||
two different releases of one film (deletable redundancy).
|
||
|
||
TV episodes (SxxEyy in the name) are grouped separately: their uniform runtime
|
||
would otherwise collapse a whole series into one "duplicate" group.
