The "v4" suffix was a holdover from iterative project restarts. There is now one psxrecomp; all identifiers, include guards, cmake variables, function names, log strings, schema tags, and tool paths drop the v4 suffix. Changes: - PSXRECOMP_V4_ROOT → PSXRECOMP_ROOT (cmake) - PSXRECOMP_V4_RUNTIME_SOURCES/_INCLUDE_DIRS/_BIOS_GENERATED → no V4 - psxrecomp_v4_add_runtime_target → psxrecomp_add_runtime_target - PSXRECOMP_V4_*_H include guards → PSXRECOMP_*_H - "psxrecomp-v4" log/window strings → "psxrecomp" - Schema version strings in recompiler JSON output - Tool script hardcoded absolute paths updated Co-Authored-By: Claude Sonnet 4.6 (1M context) <noreply@anthropic.com>

* card_read_summary.h — non-evicting evidence ring for the first 32
|
|
* completed memory-card reads.
|
|
*
|
|
* The card-txn ring (256 entries, evicting) covers recent activity
|
|
* but the long history is gone by the time we audit. This ring is
|
|
* fixed-size and STOPS recording after 32 entries, so the FIRST 32
|
|
* successful reads post-CROSS are preserved indefinitely.
|
|
*
|
|
* Each entry captures the SIO-layer evidence at the MC_READ_END
|
|
* transition: slot/cmd/sector/checksum/first 16 bytes/cycle counts/
|
|
* caller function. The destination RAM pointer is filled in later
|
|
* by the chain-handler trace (Phase 3).
