Summary

Automodel, unsloth, RL, and the data-designer retrieval-mine job authenticate their file_io and model_entity task containers with --service-name customizer (or unsloth, rl). None of those are registered service principals. The auth service only recognizes customization, the identity already used everywhere else in the platform: job telemetry, authz scopes, the plugin registry. So every job step call to the Files or Jobs API gets rejected, and the user sees a 502: Authorization service error at the first download step instead of a real reason.

This broke during the NeMo Platform to NeMo Helix rename (#2293). That commit touched the auth service's allow-list logic, but these four callers kept their old, never-registered names instead of switching to the one the platform recognizes.

Fix

Point every caller at customization, the name that's already allowed by the auth service. --service-source is not touched; it's a separate telemetry field (what shows up in job metadata) and still distinguishes automodel/unsloth/rl/retrieval-mine from each other. No changes to job provenance or tracking, only which identity the container presents when it calls the platform.

Verification

  • Confirmed the exact bug directly against the function that rejects the request (_available_service_names): none of customizer, unsloth, rl are in the allowlist today; customization is.
  • Confirmed the fix the same way: all four callers now resolve to customization, which the allowlist accepts.
  • Added a regression test (test_service_principal_allowlist.py) asserting every backend's --service-name is an allowed principal, so a future backend can't silently drift out of this again.
  • Updated the two existing compiler tests that asserted the old (broken) values, plus the retrieval-mine test and a stale help-text example.
  • Full relevant suite (automodel, RL, data-designer retrieval, the new test) passes: 118/118.

What I could not do: run a real job end to end against a cluster with auth enabled. That check happens server-side in the platform's own controller process, so a client-side fix doesn't take effect until this is deployed. I verified against the actual code path that gates the decision, not a live job.

Root cause tickets

NMP-238, ASTD-648

…ervice

automodel, unsloth, rl, and the data-designer retrieval-mine job all pass
--service-name customizer/unsloth/rl to the file_io and model_entity task
containers. None of those names are registered service principals: the
auth service only recognizes "customization" (see the platform service
registry and CUSTOMIZATION_JOB_SOURCE). Every job step call back to the
Files/Jobs API is rejected, surfaced to the job as a 502 "Authorization
service error" at the first download step.

--service-source is untouched; it's a separate telemetry field and still
distinguishes which backend produced a job.

Verified against the exact function that rejects the request
(_available_service_names): the old values are absent from it, the new
value is present, for all three backends plus the retrieval job path.
Added a regression test asserting every backend's --service-name is an
allowed principal, so a new backend can't drift out of this again.

📝 Walkthrough

Walkthrough

Task commands in Automodel, RL, Unsloth, and retrieval now use customization for their service values. Help examples and compiler expectations reflect the updates. A new test checks six commands against the service names in AuthServiceConfig.

Make this test collect with the package’s declared dependencies.

A package-scoped nhx-customization-common test environment cannot import these backend packages or nhx-auth: none is a declared project or dev dependency. Test collection fails before the allowlist assertion runs. Move this cross-service test to a workspace integration suite, or add the packages as test-only dependencies. The root workspace installs additional plugins, which can hide this failure. (raw.githubusercontent.com)

ruff wanted the pytest import and the local imports on separate groups
with no blank line between them collapsed. Also dropped the NMP-238
reference from the test docstring: it tripped the rename-consistency
check (matches the legacy NMP acronym as plain text), and ASTD-648
alone is enough context for why the test exists.
