The whole-launch identity comparison incorrectly rejected reviewed collector source updates. Keep only aisimulate_revision outside immutable identity equality and include its exact accepted and collection values in the required review. Signed-off-by: Yiming Liu <yimingl@nvidia.com>
Whole-policy equality rejected archived deadline overrides and explicit empty CLI lists before memory verification. Separate only the supported collection controls for exact review, preserve the frozen plans and hashes, and retain strict serving configuration and raw memory checks. Collection-control review does not establish timing or measurement equivalence. Signed-off-by: Yiming Liu <yimingl@nvidia.com>
📝 Summary
Merge Risk: 🔵 Low · up to Readiness checks for imported profiles can return incomplete timing reports with an unclear error when a checkpoint has no runtime observation index. The effect is narrow and does not relax any validation, so the change is mergeable with a small follow-up fix. Pre-merge checks |

Explanation
The visible description names a pytest command and passing result, lists relevant negative and boundary cases, and states that Fast CI and Full CI were pending. It does not show the complete evidence classification for local, fake-runner, parity, and production results. The description ends mid-sentence, and no full PR description is available in the checkout. Therefore, the required evidence distinction and the absence of any later inactive-workflow claim cannot be verified.
Resolution
Provide the complete PR description, or enable the native PR-description lookup, so the omitted evidence sections can be checked for explicit local/fake-runner/parity/production labels and for inactive nested workflows presented as hosted CI.

- Around line 303-312: In the runtime binding built in `collection_readiness`,
avoid converting a missing `runtime_observations` value to `Path(".")`: skip
index hashing and add an explicit blocker when the value is absent, while
preserving per-cell reporting. Resolve relative index paths against the
appropriate checkpoint or campaign location, and use consistent path resolution
in `verify_collection_runtime_bindings` so symlinked and relative paths compare
correctly.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win
Build the runtime binding outside the per-cell timing loop, and handle a missing index explicitly.
Path(checkpoint.get("runtime_observations", "")) becomes Path(".") when the checkpoint has no index. file_evidence(Path(".")) then raises IsADirectoryError. The campaign-level except catches it after only the first cell has been appended. The remaining cells of that campaign are missing from report["cells"] and selected. The only blocker is an unclear [Errno 21] Is a directory: '.'. Before this change, the same checkpoint still produced complete per-cell timing reports.
There is also a related mismatch. file_evidence returns path.resolve(). verify_collection_runtime_bindings (runtime_collection.py, Line 325) compares that value against Path(checkpoint["runtime_observations"]).absolute(). Assume the recorded path goes through a symlinked directory or is relative. Then the binding fails with "runtime checkpoint does not match the bound plan/index/attempt", even for an unchanged campaign.
Fix:
- Skip index hashing when the field is absent, and add an explicit blocker.
- Resolve relative paths against the checkpoint or campaign location.
- Use the same normalization on both sides of the comparison.

303 - 312:
In the runtime binding built in `collection_readiness`, avoid converting a
missing `runtime_observations` value to `Path(".")`: skip index hashing and add
an explicit blocker when the value is absent, while preserving per-cell
reporting. Resolve relative index paths against the appropriate checkpoint or
campaign location, and use consistent path resolution in
`verify_collection_runtime_bindings` so symlinked and relative paths compare
correctly.

Why and what changed
Onboarding memory validation rejects a collection when its recorded configuration name differs from the accepted probe, when prefill and decode were collected in separate attempts, or when reviewed collector/runtime revisions changed. Bind each phase to its archived collection plan and successful attempt, validate that phase under its recorded launch, then require complete phase coverage and compatibility with the accepted profile.
The shared verifier is also used by collection readiness. Exact runtime, deployment, AISimulate source and supported collection-control changes require a recorded review; model revision, precision, topology, scheduler/graph settings, cache geometry, artifact integrity and rank-local capacity remain strict. Semantically empty CLI overrides normalize without changing the archived plan. Verified repository names and their pinned snapshot paths compare as the same checkpoint. Collection-control review establishes memory compatibility only. Existing single-campaign callers retain their strict behavior.
