📝 WalkthroughWalkthroughThe Customizer SDK now uses typed Nemo clients, endpoint models, and shared contexts for job and health operations. Customizer CLIs now expose submit and explain without run. Backend documentation, dependencies, resource wiring, and tests reflect the new contracts. ChangesCustomizer SDK migration

Suggested reviewers: Merge Risk: 🔵 Low · up to This migration changes job creation and retrieval from stateful handles to typed response objects, so existing consumers that still rely on the old status-polling behavior may need updates. The PR is mergeable with explicit owner awareness to confirm downstream migration; the remaining documentation follow-ups are localized. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Make the Ruff commands executable.
<touched-python-files> is an unresolved placeholder. A reader cannot run these commands as written. Replace it with concrete paths or a command that expands the changed Python files.
As per coding guidelines: use concrete, tested commands in documentation.

Use a documentation substitution for the plugin name.
nemo-customizer-plugin is a product name in prose. Use the configured Sphinx substitution so renamed distributions do not leave stale ownership guidance.
As per coding guidelines, “Never hardcode product names; use substitutions in Sphinx configuration.”

Add RL to the status quick reference.
Line 107 includes RL in the submit-only contract, but the status row at Line 309 still lists only automodel|unsloth. Add rl to the documented job ID pattern so RL users can follow the quick reference.

TL;DR
Migrates the Customizer jobs SDK for Automodel, Unsloth, and RL onto typed
NemoClientendpoint resources while preserving theclient.customization.<backend>.jobsnamespace. The Customizer CLI now exposes onlysubmitandexplainfor these remote training backends instead of registering a localruncommand that could only fail.Details
This adds typed Customizer endpoint definitions and DTOs for health, job create/list/retrieve, then rewires the shared backend SDK factory to build sync/async Customizer contexts from
NemoClient/AsyncNemoClient. Customizer-owned calls return typedNemoResponseor paginated responses, and status/log helpers delegate to the core Jobs SDK so lifecycle data comes from the canonical Jobs service routes.The Customizer hub now passes a typed context to contributor SDK resources, so Automodel, Unsloth, and RL share one implementation path. The
nemo-customizer-pluginno longer depends directly onnemo-platform; it relies onnemo-platform-pluginclient resources.For the CLI, Customizer contributors no longer register a generated
runverb. The backend commands remain submit-only withnemo customization <backend> submit JOB_JSON, and the docs, skill guidance, and focused tests were updated to reflect thatrunis not part of the Customizer training surface.
