Recovers how a script method id maps to its implementation, the foundation for
body-level normalisation. Each CMC_*_Runner::run is a switch(id) (vtable slot 17);
every case is the method body — inline (MSVC6) or a tail-call to a separate
show()/load() (MSVC8). The extractor parses the jump table at the disassembly
level (Ghidra's decompiler jump-table recovery silently dropped the big runners),
fingerprints each case by its ordered CALL anchors (Class::method / vtbl+0xNN),
and expands thin wrappers one level so MSVC8 lines up with MSVC6.
Validated on the golden pair: Animo SHOW..RESUME (id 1-4) yield identical leaves
(getAnimo + vtbl+0xa0/0xa4/0x4c/0x50) across both compilers. Coverage 30/32
runners; Piklib 475 / BlooMoo 619 dispatch rows.
- extract_engine_surface.py: extract_method_dispatch (schema_version -> 4)
- snapshots regenerated with the method_dispatch axis
- ams: Snapshot.method_dispatch; diff axis keyed (owner,id) on [impl,calls] with
method-name join; render METHOD BODIES section; cli --only dispatch; owner filter
- UI: "Ciała metod" diff axis + browse tab
- tests: body-change unit + cross-compiler vtbl assertion -> 29/29

Ranks catalogued engine versions by how much of their CMC_* surface they share,
which (unlike a binary fuzzy hash) stays meaningful across compilers — the golden
pair PIKLIB8/MSVC6 vs bloomoodll/MSVC8 scores 85%.
- similarity.py: jaccard, surface_similarity (per-axis + pooled overall),
fuzzy_similarity (ssdeep via ppdeep, secondary signal)
- service.similar_snapshots + GET /snapshots/{id}/similar?min=N (SimilarHit)
- UI: "Podobne wersje" panel in the snapshot browser (overlap bar + ⇄ diff)
- tests: 6 new (jaccard, identical/disjoint, golden pair 0<x<100, fuzzy,
endpoint + min filter) -> 28/28

Adds a "+ wgraj" control to the sidebar that uploads an ISO/ZIP/DLL to the
acquisition endpoint and tracks the job to completion, then refreshes the
version list so the new snapshot appears without a reload.
- index.html: upload form + #jobs panel in the sidebar
- app.js: submitUpload() (FormData → POST /jobs), pollJobs() (2.5s while any
job is queued/started; finished → load(); failed → inline error)
- style.css: mini-btn / upload form / job rows + queued/started badges
Verified: node --check clean; uvicorn serves /ui assets 200 and GET /jobs.

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`.
