- kernel: gsp_cuda_bridge (QMD launch capture, debugfs job/out/done, param+output resolution cached from inline writes), sema drain fixes (never hold/starve a channel), GR ring autopin + counter autoreg, per-page push reads, counter-derive gate; module builds clean
- 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
- debug/risc-v-gsp-rm-vm: Phase S simulator wave (GSP device model, boot ladder, triage/re-demo harnesses, docs 30-41), GPGPU-sim scaffolding
- STATE-CURRENT/docs updates
debug: green-eye wave 2 - injection SDK, Frida-like calls, Ghidra control bridge, long-term docs

Adds to debug/risc-v-gsp-rm-vm/:
- Session.call / run_until: Frida-like remote function calls and run-to-cursor,
with register restoration; verified live (rpc_ping -> 0xaffe).
- symbol+offset target resolution (gsp_ctrl+0x10) across all APIs and the REPL.
- Injection SDK (sdk/) and 'greeneye inject': position-independent RV64 service
blobs (verified zero relocations), loaded into RAM, registered in the demo
handler table, and invoked either directly or through the firmware mailbox
dispatcher. Demo ABI extended: mailbox 16..23 selects slots, arg0 carries the
service command, arg2 added (struct now 0x190; schema updated).
- Ghidra control bridge (greeneye ghidra + GreenEyeControl.java): run-until-here,
breakpoints, memory/register access, remote calls, hit export; verified
end-to-end with Ghidra headless (run_until reached rpc_sum from a GhidraScript).
- MarkGreenEyeHits.java fixed for the Ghidra 12 createBookmark API; verified
headless together with ExportForGreenEye.java.
- Analyzer renders a QEMU first-fault table for probe sessions (fault count,
epc with firmware vaddr translation, access address/size, reason).
- Tests now 35 green, including injection, Ghidra bridge, remote call, run-until
and REPL command smoke tests.
- Documentation: docs/11-16 (GSP RM service developer guide, injection SDK
specification, Ghidra control, adversarial interoperability guide, agentic
GSP IDE, custom simulator design) and GREEN-EYE-ROADMAP.md (long-term H1-H7
program); doc maps and the project RISC-V VM doc updated.
