Background

Live end-to-end test of Community GPU CI (#1249) after the expression-parse
fix in #1252. No functional change; this PR exists only to trigger the
workflow on a genuinely clean families/ change (previous attempt, #1251,
turned out to conflict with already-merged content).

Exit Criteria

Community GPU CI fires automatically on this PR (self-service, no label),
reserves a GPU, builds, runs the bert family tests, and reports a commit
status back.

Implementation

Adds a comment-only line to families/bert/support.py. No behavior change.

📝 Summary

Summary

Adds comment-only documentation to families/sam3/support.py and .dockerignore. No functional behavior or public declarations change.

Architecture impact

  • Family-owned files: families/sam3/support.py.
  • Shared surfaces: .dockerignore.
  • Dependency directions: No new dependencies.
  • Affected consumers: The documented GPU CI workflow and consumers of .dockerignore may be affected. The supplied evidence does not confirm the BERT path or the exact CI workflow behavior.
  • Blast-radius questions: Confirm that the intended Community GPU CI workflow selects the changed families/ path. Confirm that the documented payload and .dockerignore comments match the intended live-fire test.

Status: HUMAN REVIEW REQUIRED. The supplied evidence does not include current review findings, CI results, or confirmation that the intended GPU workflow ran.

Walkthrough

The change adds comments to families/sam3/support.py and .dockerignore. The comments document a live-fire test payload and related direct-families retention and families/SAM3 changes. No executable code changes.

Explanation

The patch changes a shared surface, but the description does not justify it. The authoritative diff changes families/sam3/support.py and the root .dockerignore, while the description claims families/bert/support.py. Both additions are comments, and non-comment content is unchanged. The root .dockerignore serves root-context builds such as tools/ci/docker_image.py and docker-compose.yml; the described Community GPU build uses the requirements context. The description provides no model-agnostic need, shared-consumer impact, reason the change cannot remain family-owned, or completed validation evidence.

Resolution

Remove the unrelated .dockerignore comment and correct the description to identify the actual families/sam3/support.py change. Then this is a family-local comment-only change. If the shared-file change is required, update the description with the concrete root-build consumers, the model-agnostic need, compatibility impact, completed validation result, and the reason the implementation cannot remain in families/sam3/.

The second real live trigger of community-gpu-ci.yml (PR #1260, after
fixing the failure() expression and impact-JSON bugs in #1252/#1261)
reached provision-and-test and actually reserved a GPU, but failed with:

  ERROR: permission denied while trying to connect to the docker API
  at unix:///var/run/docker.sock

right on the first docker command after instance creation. git clone
succeeded on the same instance immediately before it, so SSH access
itself was fine; the instance's docker-group membership for the SSH
session had not propagated yet. Our earlier manual proof-of-concept
never hit this because there was always a natural delay (multiple
separate exec calls, manual inspection) between instance creation and
the first docker command; this workflow goes from reserve straight
into docker build with no gap.

Fix: prefix both docker invocations (build and run) with sudo, which
sidesteps the group-membership timing question entirely instead of
depending on it. Confirmed teardown already worked correctly on the
failed run (brev delete ran via the always() step, no orphaned
instance), so this is the last known blocker from the two prior
live-fire attempts.

Move the CI marker to the BERT family.

tools.test_impact.classify maps families/sam3/support.py to SAM3, and the GPU runner uses that selection directly. This change does not select BERT. Move it to families/bert/support.py if the objective is to run BERT tests.

…ared change

No functional change. Touches families/sam3/support.py (a specific
family) and .dockerignore (a shared file) in the same commit, so
tools.test_impact resolves scope: "all" while direct_families still
lists sam3. Verified locally: selected_families('all', ..., ...)
returns ('bert', 'gpt2', 'qwen', 'sam3', 'timm_vit', 'whisper') -
the 5-family smoke set plus sam3 retained, confirming NVIDIA#1277's fix
for the case Chaofeng and Zhenshan discussed (family + shared-dir
change in one PR should not drop the touched family).
