## [2026-05-20] — Release parser v2 (EASY + SHITTY)
|
||||
|
||||
### Added
|
||||
|
||||
- **Release parser v2 — EASY path live** (`alfred/domain/release/parser/`):
|
||||
new annotate-based pipeline (tokenize → annotate → assemble) drives
|
||||
releases from known groups. Exposes `Token` (frozen VO with `index` +
|
||||
`role` + `extra`), `TokenRole` enum (structural/technical/meta families),
|
||||
and `GroupSchema` / `SchemaChunk` value objects.
|
||||
- `pipeline.tokenize`: string-ops separator split (no regex), strips
|
||||
a `[site.tag]` prefix/suffix first.
|
||||
- `pipeline.annotate`: detects the trailing group right-to-left
|
||||
(priority to `codec-GROUP` shape, fallback to any non-source dashed
|
||||
token), looks up its `GroupSchema`, then walks tokens and schema
|
||||
chunks in lockstep — optional chunks that don't match are skipped,
|
||||
mandatory mismatches abort EASY and return `None` so the caller can
|
||||
fall back to SHITTY.
|
||||
- `pipeline.assemble`: folds annotated tokens into a
|
||||
`ParsedRelease`-compatible dict.
|
||||
- `parse_release` (in `release.services`) tries the v2 EASY path first
|
||||
and falls through to the legacy SHITTY heuristic on `None`. Legacy
|
||||
SHITTY/PATH OF PAIN behavior is unchanged.
|
||||
- Knowledge: `alfred/knowledge/release/release_groups/{kontrast,elite,
|
||||
rarbg}.yaml` declare the canonical chunk order per group, loaded via
|
||||
new `ReleaseKnowledge.group_schema(name)` port method.
|
||||
- Tests in `tests/domain/release/test_parser_v2_{scaffolding,easy}.py`
|
||||
cover token VOs, site-tag stripping, group detection, schema-driven
|
||||
annotation (movie, TV episode, season pack with optional source),
|
||||
and field assembly.
|
||||
|
||||
- **Release parser v2 — enricher pass** completes the EASY pipeline.
|
||||
The structural schema walk now tolerates non-positional tokens
|
||||
between chunks (instead of aborting on leftover tokens), and a second
|
||||
pass tags them with audio / video-meta / edition / language roles.
|
||||
Multi-token sequences from `audio.yaml`, `video.yaml`, `editions.yaml`
|
||||
(e.g. `DTS.HD.MA`, `DV.HDR10`, `TrueHD.Atmos`, `DIRECTORS.CUT`) are
|
||||
matched before single tokens. Channel layouts like `5.1` and `7.1`
|
||||
(split into two tokens by the `.` separator) are detected as
|
||||
consecutive pairs. Sequence members carry an `extra["sequence_member"]`
|
||||
marker so `assemble` extracts the canonical value only from the
|
||||
primary token. KONTRAST releases with audio / HDR / edition / language
|
||||
metadata now produce a fully populated `ParsedRelease`.
|
||||
|
||||
- **Streaming distributor as a separate dimension** from encoding source.
|
||||
New `alfred/knowledge/release/distributors.yaml` (NF, AMZN, DSNP, HMAX,
|
||||
ATVP, HULU, PCOK, PMTP, CR) feeds a new `ReleaseKnowledge.distributors`
|
||||
port field, a `TokenRole.DISTRIBUTOR` annotation, and a
|
||||
`ParsedRelease.distributor` field. `WEB-DL` stays the source; the
|
||||
platform that produced the release is now recorded distinctly. The
|
||||
five entries (NF, AMZN, DSNP, HMAX, ATVP) were correspondingly removed
|
||||
from `sources.yaml`.
|
||||
|
||||
- **Real-world release fixtures** under `tests/fixtures/releases/{easy,shitty,path_of_pain}/`,
|
||||
each documenting an expected `ParsedRelease` plus the future `routing`
|
||||
(library / torrents / seed_hardlinks) for the upcoming `organize_media`

### 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]`),

"""Release parser v2 — annotate-based pipeline.
|
||||
|
||||
This package is the future home of ``parse_release``. It restructures the
|
||||
parsing logic around a **tokenize → annotate → assemble** pipeline:
|
||||
|
||||
1. **tokenize**: split the release name into atomic tokens.
|
||||
2. **annotate**: walk tokens left-to-right, assigning each one a
|
||||
:class:`TokenRole` (TITLE, YEAR, SEASON, RESOLUTION, …) using the
|
||||
injected :class:`~alfred.domain.release.ports.knowledge.ReleaseKnowledge`.
|
||||
3. **assemble**: fold the annotated tokens into a :class:`ParsedRelease`.
|
||||
|
||||
The pipeline has three internal paths driven by the detected release group:
|
||||
|
||||
- **EASY**: known group (KONTRAST, RARBG, …) with a schema-driven layout
|
||||
declared in ``knowledge/release/release_groups/<group>.yaml``.
|
||||
- **SHITTY**: unknown group, best-effort matching against the global
|
||||
knowledge sets, with a 0-100 confidence score.
|
||||
- **PATH OF PAIN**: score below threshold OR critical chunks missing —
|
||||
signaled to the caller, who decides whether to involve the LLM/user.
|
||||
|
||||
Today the package exposes scaffolding only (token VOs and a thin pipeline
|
||||
stub). The legacy ``parse_release`` in ``release.services`` keeps serving
|
||||
production until each piece of the v2 pipeline is wired in.

Three stages:

1. :func:`tokenize` — release name → ``list[Token]`` (all UNKNOWN), plus
|

a separately-returned site tag (e.g. ``[YTS.MX]``) that is never

tokenized.
|

2. :func:`annotate` — promote each token's :class:`TokenRole` using the

injected knowledge base. Two sub-passes:

|

a. **Structural** (schema-driven, EASY only). Detects the group at

two structural chunks, any number of unmatched tokens may

b. **Enrichers** (non-positional). Walks UNKNOWN tokens and tags
|

audio / video-meta / edition / language roles. Multi-token
|

sequences (``DTS.HD.MA``, ``DV.HDR10``, ``DIRECTORS.CUT``) are

matched first, single tokens after.
