Adds lib/sub-rest-fetch.py: direct OpenSubtitles REST, looks up subs by
per-episode IMDB id (e.g. tt0511631) instead of the plugin's
(parent_imdb_id, season, episode) combo path. This sidesteps shows where
library numbering diverges from OpenSubtitles' catalogued numbering --
American Dad uses Hulu S1=7 eps; OS uses Fox S1=23 eps; the plugin path
returns 0 hits past S01E07 even though every per-episode IMDB id is
correct.
Recipe README updated to surface the two paths (v1 plugin / v2 REST) and
recommend v2 by default. American Dad run log now shows 19/58 episodes
subbed (S01 7/7 via v1, S02E01-E12 via v2). S02E13-S04 (39 eps) deferred
to next 20/day quota windows.
Quirk fixed in v2: OpenSubtitles /download endpoint consistently returns
HTTP 503 to Python urllib.request despite identical headers/body via curl.
_curl() shim routes all OS API calls through curl. Each 503 still
consumes a download slot, so urllib path was unsafe to retry on.
Adds processes/ umbrella for repeatable acquisition workflows. First child
is subtitles/, with recipe README (executable by Claude Code), CHANGELOG,
per-show run logs, and a tested helper at lib/sub-fetch.sh.
Run on American Dad: S01 (7 eps) passed, S02-S04 (51 eps) broke. Library
uses Hulu/DSP season ordering; OpenSubtitles indexes by Fox airing order;
plugin queries by (parent_imdb_id, season, episode) so library S02E01
returns 0 hits. v2 design = direct OpenSubtitles REST with per-episode
imdb_id lookup; pending API-key registration.
