renpy.random/random get choices, sample, randrange and Random(seed); frozenset, iter and hash
are builtins. User classes may define __hash__ (dict keys), __iter__, __getitem__ and
__contains__; the converter accepts them instead of rejecting the whole class, which
removes the Perk/Skill/Status wall in SaintlyCorruption.

ATL
- Image blocks become timelines: picture steps with dissolve, parallel, contains,
finite repeat, time, function f(trans, st, at), calls of other transforms with
arguments, on hover/idle events for buttons. Animations stop when their element
leaves the page
- Pictures defined by an expression (get_face_path("base")) are drawn at show time
- Purely graphical hints (shader, mesh, gl_*, u_*) are accepted and dropped
Colour
- matrixcolor and im.matrix.* as 5x5 matrices combined with `*`, applied through SVG
filters; im.MatrixColor/Scale/Crop/Blur/Composite and Text/Image as values
Python
- match statement, re/copy/time/datetime/defaultdict/functools.partial, more
str/dict methods, Character(...) created by code
- narrator("..."), Character calls, renpy.say and renpy.show/hide with expressions in
Python blocks become script nodes
- Audit follows reachability: functions and classes nothing refers to (custom
statement lexers, unused tools) no longer block an import
Docs: README and ARCHITECTURE now describe a multi-engine library (GameMaker and
QSP planned). Tests for the new runtime pieces.

- Unsupported ATL constructs in a transform now block the import only when the
transform is used (at clause, another transform, even before its definition).
Stock screens.rpy transforms for unused screens no longer fail games
- image blocks with one picture plus linear/ease/parallel/repeat keep their
animation (image-level ATL); the renderer also starts it
- Python: skip @gui.variant/@renpy.variant functions (inactive variants), treat
@renpy.pure as transparent, read renpy.store.x as x
- Accept renpy.transition, end_replay, block_rollback and music set_pause/set_pan
as presentation-only no-ops, and implement them in the player (set_pause and
set_pan were allowed by the converter but missing at runtime)
- Skip the 0x52-URM add-on directory (in-game console / save editor) when
parsing scripts and media
- Tests for lazy ATL warnings, moving images and variants

Python sandbox
- try/except/else/finally, raise (incl. re-raise), assert, for/while ... else
- Multi-generator and dict comprehensions
- Builtin exception hierarchy; user exceptions subclass it
- Inside try, missing keys/indexes, division by zero, attribute access on None
and unknown names raise Python exceptions; lookups stay lenient elsewhere
- int()/float() raise ValueError on non-numeric strings
ATL
- converter/atl.py: set/move (linear, ease, easein, easeout), pause, repeat,
parallel, choice, block, on show/hide and named transforms become a timeline
shipped as game.json "atl"; Move() becomes a linear slide
- player/atl.ts: timeline runner wired into the renderer; `on hide` plays
before the picture is removed
- function, time, contains, matrixcolor and expressions still block the import
Tests: exceptions/ATL fixtures and runtime tests, converter ATL tests; README
and ARCHITECTURE updated.

- Converter: def/return/global/nonlocal, class (inheritance, property,
staticmethod, classmethod), lambda, *args/**kwargs and call-site unpacking.
Unsupported dunder methods, generators and unknown decorators are still refused
- Player: closures, super(), instances that survive save/load, isinstance,
hasattr/getattr/setattr, map/filter/sorted(key=), recursion limit
- audit_ir accepts calls to names, classes and methods the game defines itself;
unknown renpy.* calls still block the import. Volume/pan/pause/replay calls
are accepted as presentation-only no-ops; build.* settings are skipped
- Tests: IR fixture compiled from tests/fixtures/classes.py (tests/make_ir.py)
and run in the interpreter; converter tests updated

Checked against six real games (Ren'Py 7.5 and 8.x):
- nested labels and named menus become jump anchors inside label bodies
- call with arguments and labels with parameters (dynamically scoped)
- frame-by-frame ATL images, Movie frames, layeredimage, camera, Shake,
custom audio channels via register_channel, show text with expressions
- generator expressions in Python, no SyntaxWarning noise from decompiled code
Also:
- app.import_dir converts an unpacked game folder without changing it
- app.converter.analyze dry-runs the script part of the converter
- imports use their own "importing" status so a worker restart can't hijack them

- FastAPI backend: admin bootstrap with forced credential change, admin-created
users with one-time generated passwords, roles as permission sets
- Games and versions with content-addressed blob storage; forks copy only the
manifest, so mods share assets with the original
- Worker: archive/RPA extraction, unrpyc for .rpyc, own .rpy parser, Python
subset translated via ast, media converted to WebP/Opus/WebM
- React panel (library search, game page, upload, users, roles) and a
framework-free web player with saves, history, skip/auto, transitions
- docker compose: postgres, backend, worker, nginx on a single HTTP port
