220-231: Non-DUMP modes now correctly validate presence of a prior dumpAdding
image_check_exists(options)for the non-DUMP branch is a good safety net: refine/verify will now fail fast when there is no existing.state(and thus no prior dump) instead of silently creating a new empty state file.If your intent is that all CD dump artefacts must exist for refine/verify (e.g.,
.scram,.state,.subcode), consider extending the common helper to validate those as well, so the invariant is enforced in one place.common.ixx (1)
73-90: Newimage_check_existshelper is correct and complements overwrite checksThe new helper mirrors
image_check_overwrite’s path construction and cleanly enforces “dump must already exist” based on the.statefile. This fits well with the cd/dvd callers’ new non-DUMP behavior.If you want to avoid duplication and keep path logic centralized, you could factor out a small internal helper, e.g.
static std::filesystem::path image_state_path(const Options&), and use it from both functions.

Learning: In dvd/dvd_dump.ixx, the sector count determination logic (around lines 641-647) is intentionally centralized to support multiple sources: READ_CAPACITY, physical structures, and future options like ISO/UDF filesystem size. For Xbox/Kreon XGD discs, the physical structure sector count is correct to use because xbox::initialize() updates the layer0_ld.layer0_end_sector with the true value from the security sector before sectors_count_physical is calculated.

1-24: Module declaration relocation looks correctUsing a global module fragment for includes followed by
export module systems.xbox;is valid C++20 module structure and does not alterSystemXBOXbehavior. No issues spotted here.dvd/dvd_dump.ixx (1)
448-464: Improved dump/refine preconditions and directory handlingThe updated
dump_modehandling is solid:
- Keeping
image_check_overwrite(options)forDumpMode::DUMPpreserves existing overwrite semantics.- Guarding
std::filesystem::create_directories(options.image_path)on!options.image_path.empty()avoids the empty-path edge case.- For non-DUMP modes, delegating to
image_check_exists(options)correctly enforces that a prior dump actually exists before refine/verify.No further issues from this change.
