Robert Allan JamesandClaude Sonnet 5	c05b70c8d6	Stage B: logging policy documented, level-aware log-ring eviction built, LOG-FLUSH deferred again (FABRIC-3.md §XXXII.4) ... 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.

Robert Allan JamesandClaude Sonnet 5	2a30212bd3	Real per-VM log persistence: source attribution + ACL pin (FABRIC-3.md §XXVII) ... Wires the previously-unused vm_log_attributed_vm() into LOG-APPEND's kernel primitive so persisted log records carry a trustworthy source (the real attributed VM's registry name, or "HADES" pseudo-source) instead of a caller-supplied, trivially forgeable string. Drops src-addr/src-u from LOG-APPEND's stack signature accordingly. Pins LOG-APPEND via bare ACL-PIN in Artemis's own init.4th, matching BIRTH/CAPSULE-BIRTH's precedent for a privileged word that can't reach the shared, host-portable ACL.4th. Also fixes two console-banner nitpicks: a mis-rendering em dash (U+2014) in the boot banner, and drops "Emergency" from the CLI banner text. Doc corrections to artemis_sig.h/zuse_eligibility_list.h reconciling the three fixed devblock ranges now in play. LOG-FLUSH (the intended normal entry point) and level-aware log eviction remain open, flagged not fixed. Re-verified clean boot to ok> on all 3 architectures after every change. riscv64 showed one new, unrelated virtio_blk write-timeout anomaly during Artemis's early physics self-test (self-recovered, boot unaffected, sector doesn't map to the log region) -- flagged, not investigated.
