Static HTML/CSS/JS served by FastAPI (mounted at /ui, / redirects there),
talking to the existing JSON API — no node/npm, no bundler.
- games/versions sidebar with A/B version selectors
- visual 4-axis diff (types/methods/events/fields, +/- struct_layout) with
+/-/~ rows, per-axis counts, class (owner) filter, moved-methods section
- single-snapshot browser (tabs + live filter)
- app.py mounts StaticFiles(html=True) last so API routes win; / -> /ui/
Smoke-tested live on uvicorn: /, /ui/ and assets serve 200; UI wiring drives
the same /games and /diff endpoints verified end-to-end. app.js passes
`node --check`.

Modular-monolith backend over SQLAlchemy (SQLite by default, Postgres-ready
via DATABASE_URL). The full snapshot.json is stored verbatim; diffing reads it
back through the ams.diff engine, so the DB never mirrors the snapshot schema.
- ams.api.db/models/schemas/service : Game 1-N Snapshot, sha256-deduped upsert
- routes: POST/GET /games, POST/GET /snapshots (import, deduped), GET /diff
(?old&new[&owner]) running compute_diff on stored snapshots, /health
- ams.api.importer : bulk CLI loader (python -m ams.api.importer --game ...)
- run: uvicorn ams.api.app:create_app --factory
11 tests pass (6 diff + 5 API via TestClient over the golden pair). Smoke-tested
live on uvicorn: import -> /snapshots -> /diff returns the BlooMoo deltas.

Standalone CLI that diffs two engine-surface snapshots across all four axes,
the foundation the FastAPI/DB layer will sit on.
- ams.snapshot : typed access to a snapshot.json
- ams.diff : keyed set-diff per axis (added/removed/changed) + cross-owner
method-move detection; types keyed by (script_name,
via_module_iface) so the dual MULTIARRAY stays stable;
filter_by_owner for per-class focus
- ams.render : human-readable report (+/-/~), owner-grouped
- ams.cli : python -m ams OLD NEW [--owner C] [--only ...] [--json]
6 tests pass, incl. an integration test over the committed golden pair
(asserts BlooMoo adds GRBUFFER/INTERNET, MOUSE grows 104->128, Animo gains
GETFPS, Animo script fields unchanged).

Ghidra headless post-script (pyghidra/Jython) that extracts the scripting
"surface" of Aidem Media engine DLLs into a versionable snapshot.json, for
diffing engine versions. All four axes validated on the golden pair
(PIKLIB8.dll / MSVC6 vs bloomoodll.dll / MSVC8):
- types : CMC_ObjectsContainer::resolve factory ladder
(script name -> C++ class, ctor, object size; + dispatch_addr,
via_module_iface for the dual MULTIARRAY branch)
- methods : CMC_*_Runner::prepareMthHashSet (name -> id) + inheritance chain
- events : CMC_*::getBehavioursList (ordered per-class list)
- fields : CMC_* ctor -> CMElement::getProperty<T>Value (name + type)
(+ bonus struct_layout: this+offset stores via decompiler P-code)
Extraction rests on semantic anchors (call targets, referenced string
literals, push/immediate operands), never decompiled-C text, so the same
script works across both compilers despite ILT stubs, undefined string
literals, unnamed FUN_ ctors and an MSVC6 inline-strcpy off-by-one.
