 ### Changed
 
+- **Release parser v2 — SHITTY simplified to dict-driven tagging**.
+  The legacy ~480-line heuristic block in `release/services.py` is gone;
+  `pipeline._annotate_shitty` does a single pass that looks each token
+  up in the kb buckets (resolutions / sources / codecs / distributors /
+  year / `SxxExx`) with first-match-wins semantics, and the leftmost
+  contiguous UNKNOWN run becomes the title. `annotate()` no longer
+  returns `None` — SHITTY is the always-on fallback when no group schema
+  matches. `services.py` shrunk from ~525 to ~85 lines. Four fixtures
+  (`deutschland_franchise_box`, `sleaford_yt_slug`,
+  `super_mario_bilingual`, `predator_space_separators` — the last one
+  moved from `shitty/` → `path_of_pain/`) are now marked
+  `pytest.mark.xfail(strict=False)` documenting PoP-grade pathologies
+  that SHITTY intentionally won't handle. `ReleaseFixture` grows an
+  `xfail_reason` field; the parametrized suite wires the xfail mark
+  automatically.
+
 - **`parse_release` tokenizer is now data-driven**: it splits on any character
   listed in `separators.yaml` (regex character class) instead of `name.split(".")`.
   This makes YTS-style releases (`The Father (2020) [1080p] [WEBRip] [5.1] [YTS.MX]`),
