Scripts + workflow for extracting Twitter/X posts and threads into
Markdown with associated media. Mirrors the scripts/video_analysis/
pattern. Standalone requirement: zero imports from src/, conductor/,
or scripts.video_analysis — copy-pasteable to another repo with only
gallery-dl as the external dep.
5 modules: __init__.py, error_types.py (Result[T, ErrorInfo] +
ThreadData/PostData typed dataclasses), fetch_thread.py (gallery-dl
subprocess for URLs + html.parser fallback for local HTML),
download_media.py (stdlib urllib, idempotent), render_markdown.py
(YAML front-matter + per-post sections + ./media/ links).
Reference project: C:\projects\forth\bootslop — the corpus feeds
bootslop's scripts and reference-generation pipeline. Acceptance
corpus: 8 threads (@NOTimothyLottes x6 + @VPCOMPRESSB x2) extracted
to tests/artifacts/twitter_threads_corpus/. The ?s=20 quote-share
suffix on the @VPCOMPRESSB URLs must be stripped by fetch_thread.py
before acquisition (added to FR2 as URL normalization).
5 phases / 23 tasks. 8 verification criteria (VC1-VC8). TDD red-first
on the pure-function modules (render_markdown, types, media naming).
