Suggested reviewers: Merge Risk: 🟡 Moderate · up to The PR prevents normal intermediate steps from deleting shared job storage, but certain missing-step and cleanup-failure paths can still remove the workload without reliably proving final-step ownership or preserving a recovery path. This can cause premature loss of training data or leave persistent job data behind, so merge requires explicit owner awareness or follow-up. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In `@services/automodel/tests/test_job_context.py`:
- Line 42: Update the test setup and precedence cases around from_env() to clear
both current and legacy persistent-storage and job-step-config environment
variables before each assertion. In the precedence test, explicitly set
CURRENT_PERSISTENT_JOB_STORAGE_PATH_ENVVAR so it is the intended
higher-precedence value, while preserving the existing legacy alias coverage.
In `@services/unsloth/src/nmp/unsloth/tasks/training/__main__.py`:
- Line 120: Initialize persistent_root with get_job_storage_path_from_env()
instead of the current environment lookup before calling remap_job_storage_path,
preserving the compatibility behavior that resolves the mounted job storage root
when only the NEMO variable is set.

Keep final-step storage cleanup retryable.
If the final Volcano step completes before the aggregate job becomes terminal, the helper returns False. Both branches then delete the Volcano job. Later cleanup cannot retry the persistent-storage deletion, so the job PVC can leak.
Distinguish a non-final-step denial from an aggregate-status delay. Retain a retryable cleanup record for the final step before deleting its Volcano job.

Summary
Fix the Customizer container regressions exposed by Platform-Deploy by keeping model metadata schema-safe, running Customizer task steps on container execution profiles, tolerating job-storage path skew, and preserving persistent job storage until the final platform step. Before, a successful intermediate download step could be cleaned up and delete the shared job directory before training; after, task storage remains per-step while persistent job storage is removed only when final-step cleanup is eligible.
