Policy decided for the kernel-only audit scope: an interactive command's direct response stays on console_println/console_puts; everything else (state transitions, background diagnostics, audit trails) routes through log_message() at the appropriate level, matching capsule_mint.c's verify_mint() precedent. Documented, not code-swept here -- reclassifying individual sites is Stage D's job. LOG-FLUSH deferred again, explicitly: the per-VM log buffer its own doc comment presumes (vm_log_buffer.h) doesn't exist anywhere in the tree -- building it is real feature work needing its own scoped stage. Level-aware eviction built: log_region_append() now reads the oldest ring slot's own level before evicting it, protecting ERROR/WARN records from being pushed out by INFO/DEBUG churn -- drops the incoming low-priority record instead. Found and fixed an adjacent bug while making this change: the prior two-valued return contract would have made a benign "dropped by design" outcome indistinguishable from a genuine write failure to its one caller, which unconditionally set vm->error on any nonzero return. Changed to a three-valued contract (0 success, 1 dropped by design, -1 genuine failure). Three-arch clean qemu acceptance passed. Eviction path itself not live-exercised (needs 128+ LOG-APPEND calls to fill the ring) -- flagged, matching this project's own precedent for that kind of gap.
