📝 WalkthroughWalkthroughThe change updates PTO-ISA checkout resolution and cache identity. It migrates A2A3 and A5 onboard workspace handling to unified PTO APIs. It adds SDMA session validation and source-based tests. ChangesRuntime setup and cache identity

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The PR changes dependency acquisition and asynchronous DMA workspace setup, but configured dependency mirrors are currently ignored and certain A5 build or allocation failures can expose invalid or conflicting workspace state. The PR should not merge until these bounded build-integrity and runtime-failure paths are fixed or explicitly accepted by the owners. Sequence Diagram(s)sequenceDiagram

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Apply PTO_ISA_CLONE_URL to clone acquisition.
get_pto_isa_clone_url() has no effect. _clone() still passes only _PTO_ISA_GITHUB_HTTPS and _PTO_ISA_GITCODE_HTTPS to _clone_from_remote().
When a build environment requires its configured mirror, the build still contacts the fixed remotes and can fail. Pass the configured URL into the acquisition path, and keep the fallback behavior explicit.

Summary
Adapt simpler async workspace integration to the unified PTO-ISA workspace interface.
SIMPLER_ENABLE_PTO_URMA_WORKSPACE=ON.Dependency
pto_isa.pinis updated tofe2f68dac50a608c3bf11ac8d3438cd78fef0d98, which points to the PTO-ISA version after the async workspace interface was unified. This simpler PR depends on that PTO-ISA workspace-unification change.Validation
