<content type='text'>
- sim/libos_port.py: port-role model + two-task network (extintr handoff,
  cross-task send/reply, TASK_STATE_QUERY trap state)
- sim/msgq_attach.py: image task discovery, bounded two-task schedule,
  second-task-frontier divergence fields (first ring poll still blocked on
  post-init resume + GSP_ARGUMENTS_CACHED handoff; no fabricated polls)
- harness/state_decode.py: aggregate 'group: key=value' state parsing
  (20-gsp-phys-state-* dumps) + kv diff classification
- tests: 127 green across the five observability modules
- docs/51/53: status and changelog updates

<content type='text'>
Simulator development wave (docs 42-44): GMMU page-table entry decode with its oracle/workflow harness, FBIF observability, and MPU/LIBOS device surfaces in the device model, plus refreshed boot/machine/profile data (tu104-570.144), the qemu-line results, and the new unit tests. Docs 00/06/35-41 updated to match; harness helpers and .gitignore included.

- tools/cuda-bridge: CUDA driver-API daemon executing mail/vadd kernels on the physical GPU, CUBB2/CBD2 v2 protocol, layout check + self-tests
- tools/guest-diag + tools/cuda-ab: scanner/pin fixes, victory push-only mode

<content type='text'>
- gsp_phys_booter: GR promote bisection modes 4-17 (two-phase zero-field VA,
  batched entries, hVirtMemory, bare VA, KMD SKIP_CTXBUFFER_ALLOC channel,
  old-interface GPU_INITIALIZE_CTX, FBMEM context buffer, UVM-faithful PA-only,
  PATCH/PM auxiliary promotes, server-managed no-promote path); PATCH/PM
  geometry queries and buffers; pre-boot SET_REGISTRY profile selection
- gsp_phys_gpu: gsp_phys_rmcall_gr_promote clamp 0..17 and gsp_phys_srv_ctxbuf
  parameter; registry image variant with RMSetClientRMAllocatedCtxBuffer=0
- vgsp rename across kernel, scripts, tools and docs (module vgsp.ko,
  /sys/kernel/debug/vgsp/, vgsp-&lt;subsystem&gt;: log prefixes)
- risc-v-gsp-rm-debugger user-facing rename and docs/CI refresh; guest-diag
  tool updates; README/SBOM/install/Makefile sync

Live status: CE ladder and P6 guest-copy forwarding green; GR engine context
commit still open (all promote shapes accepted or cleanly refused; the channel
stays CTXNOTVALID) - see Handoff-vGPU-IO.md Addendum 21 (local).

<title>debug: risc-v-gsp-rm-debugger final pass - remove in-development notices, complete rename, adversarial-review fixes</title>

<id>urn:sha1:14cf2aa59c44a50f9a108b93d58c7cecab17d45f</id>
<content type='text'>
Remove the '# TOOL IN DEVELOPMENT - NOT READY YET!' notices from the tool docs/README/scripts and the project docs; record the removal (2026-10-02) against the tool audit (debug/risc-v-gsp-rm-vm/docs/27-TOOL-AUDIT.md), the 194-test suite and the value-validation demos (docs/25-VALUE-VALIDATION.md).

Complete the cosmetic rename to risc-v-gsp-rm-debugger in user-facing prose and commands (launcher, roadmap, docs); internal greeneye package and code identifiers unchanged.

Adversarial-review fixes: deterministic control-discovery sweep (flaky test root-caused), UUID session dirs + atomic JSON writes for concurrent runs, Ghidra bridge loopback enforcement and clean shutdown, fp register restore in Session.call, version_diff --dry-run, 30 s interrupt budget, dry-run non-destructiveness verified.

Docs: flag-removal records, link fixes, command/flag corrections (fdematch arity, port_new_device --out, trace filename), F2 orchestration note in future-eng-ops; STATE-CURRENT status refreshed.

- docs/eng-ops.md gains Part II, live physical-backend engineering
  operations: hard rules, the full module-parameter matrix, the routine
  supervised cycle and clean-release checklist, the debugfs inventory,
  how to read gsp-phys-state, a debugging scenario catalogue
  (CTXNOTVALID/promote wedge, fail-safe WPR2, unload hangs, guest wedges,
  MMU/PTE and PBDMA faults, relay symptoms), a hazard register (crash
  causes and debugging side effects), the physical-backend OODA loop, and
  the work-context map with porting flows
- architecture, implementation, operations, orientation, getting-started,
  portability, ecosystem and reference docs corrected to the current
  state: CUDA driver-API smoke green, CE-class work forwarding and
  engine-authored releases plus fault relay in place (default off), GR
  execution blocked on engine-context validity, the promote wedge and
  designed locked fail-safe, and P5 wave-2 subsumed
- internal-reference cleanup in tracked docs (no analysis-source or
  local-archive references); historical architecture document bannered
- README reading list and STATE-CURRENT frontier refreshed; new pages
  (runbook, green-eye user guide, porting sequence, porting/packaging
  notes) linked from the tree

Link check: scripts/check-docs-links.py passes (56 files, no broken links).
