Added hle_fallback: true/false per file in emulator profiles.
When a core has HLE and the file is missing, severity downgrades
to INFO instead of CRITICAL — core works without it.
verify.py builds an HLE index from emulator profiles and applies
it during severity computation. Cross-reference now skips launcher
profiles (type: launcher) and includes hle_fallback in undeclared
file reports.
33 E2E tests (4 new: HLE severity, HLE index, launcher skip,
cross-ref HLE). 0 regressions.
Based on source code analysis:
- RetroArch core_info.c:2233 — existence check only, no blocking
- PCSX ReARMed psxbios.c:28 — full HLE BIOS replacement
- Dolphin CommonPaths.h — all files optional with HLE
- snes9x — DSP HLE built-in, coprocessor files optional
Removed 7 test files (135 tests) fully covered by test_e2e.py.
The E2E creates all fixtures in setUp, exercises every code path
with real files and real functions. Single source of regression.
17 new tests covering remaining scenarios:
- md5_composite: manual calc, dirs excluded, compression-independent,
used in resolve_local_file
- storage tiers: external, user_provided, embedded, fetch_large_file
with cache hit and hash rejection
- data_directories: suppress cross-ref gaps when matched, show gaps
when unmatched
- shared groups: _shared.yml includes injection, empty group safe
- YAML inheritance: systems inherited, verification_mode override
- platform grouping: identical merged, different base_dest separated
