micheleandClaude Sonnet 5 3dd75e9e0d test: certify memory subsystem addressing (C.3) ...

int8_memory_access.v byte<->word conversion and byte-lane selection:
exhaustive 2048-address test + 6 real read/write round-trips through
the FSM handshake. 2054/2054 checks, 0 mismatches, after fixing two
bugs in the test harness itself (a same-timestep race reading a
non-blocking update one iteration late, and a behavioral memory stub
that ignored byte-lane enables on write) -- both documented as
test-side, not RTL, issues.

memory_interface.v and psram_controller.v not re-verified from
scratch: cited against coverage already established/re-confirmed
earlier in this same session (page-mode/tCEM against the ISSI
datasheet, a real pre-existing power-up request-loss bug found and
fixed), re-run clean via the Phase 0 regression harness rather than
trusted from WORKLOG text alone.

Full regression: 39/39 real tests pass.
