_aggregate_result_manifesthashes the pre-KD checkpoint and every milestone checkpoint before it reads an existing manifest. This repeats for each input revision and resume, with cost proportional to all checkpoint files. Do not bypass validation when a manifest exists; preserve geometry, tensor-shape, and immutability checks.

Inline comments:
In `@modelopt/torch/puzzletron/dataset/acquisition.py`:
- Around line 185-188: Update _load_existing_manifest to accept parsed JSON only
when it is a dictionary, continuing to the next candidate for valid non-object
values such as lists so _resolve_or_reuse_revision can fall back to
puzzletron_acquisition.json. Add a regression test covering a non-object
manifest and verifying the fallback.
In `@modelopt/torch/puzzletron/orchestration/compiler.py`:
- Around line 649-656: Update the validation error immediately after the
resource-selection branches to include resource_path, identifying whether the
invalid value came from the stage-specific or default configuration key;
preserve the existing stage ID context and remove no longer-unused assignments
only if they become unnecessary.
- Around line 645-647: Update resolve_stage_execution_specs so post.* stage IDs
still resolve to the previous "gpu" fallback when dynamic_resources is omitted,
or explicitly enforce the mapping requirement before calling
default_stage_resource. Preserve compile_campaign_plan behavior and avoid
allowing default_stage_resource to raise for supported dynamic IDs.
- Line 838: Update compile_campaign_plan so
_validate_named_mip_geometry(experiment_config) runs only after stage_filtering
and only when the compiled plan includes the mip stage. Preserve validation for
full plans while allowing convert and post.<flow>.<node> plans that
do not execute mip.
In `@modelopt/torch/puzzletron/orchestration/dataset_payload.py`:
- Line 58: Update the symlink handling around path validation and recording to
reject symlinks whose resolved targets are not files: return False during
validation, and skip or reject them before _sha256(inspected) is called during
recording. Preserve acceptance of symlinks resolving to regular files and the
existing behavior for non-symlink paths.
In `@modelopt/torch/puzzletron/orchestration/identity.py`:
- Around line 148-149: Update execution_contract_hash() so optional Slurm fields
cpu_cpus_per_task and cpu_memory_mb are omitted from the hashed payload when
unset, preserving hashes for legacy configurations; retain them when explicitly
configured. Add coverage for resuming an old active attempt and ensure
_recover_active_attempts() does not cancel it as stale.
In `@tests/unit/torch/puzzletron/test_orchestration_compiler.py`:
- Line 340: Remove the explicit mip resource override from
test_compile_routes_mip_without_model_validation_to_cpu by changing its
execution configuration to an empty value, so skip_realize_model and
realize_model.skip_validation drive the default routing and the assertion
exercises mip_resource.

What does this PR do?
Type of change: new feature
This is part 2 of a multi-part stack and builds on the VLM evaluation profiles in #2344. A fresh campaign already runs end to end with one command. This PR makes rerunning that same command after an interruption safe: valid completed work is reused and the remaining work continues.
Testing
Focused CPU tests cover planning, resume, execution, checkpoint writing, and result comparison. NeMo AutoModel integration and real GPU execution were not run locally.
