WalkthroughThe change adds immutable provider plan identities, a fail-closed offline provider runner, stronger evidence schemas, atomic harness output handling, and a restricted qualification container with static contract tests. ChangesProvider qualification
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟡 Moderate · up to The PR adds an offline qualification runner, but the current implementation can emit evidence with contradictory profile provenance or an unproven image identity, weakening trust in qualification results; it also blocks valid local planning when no image digest is needed yet. These bounded correctness and default-behavior issues should be fixed before merge. 🚥 Pre-merge checks | ✅ 3 | ❌ 2❌ Failed checks (1 warning, 1 inconclusive)

uniqueItemsand exactly five items, a mixed-scale list such as["s20-plan.json", "s22-benchexec.json", ...]still validates.

In `@benchmarks/harness/graphforge_bench/progressive_provider_run.py`:
- Around line 236-242: The build_execution_plan validation must require a
read-only in-image image-digest attestation before accepting the execution plan.
Validate that the attestation is present, well-formed, and exactly matches
image_digest, and raise ProviderRunError on absence, malformed data, or
mismatch; retain the existing admitted_plan comparison and adjacent
commit/source-tree validation.
- Around line 420-431: Update the exception handling around _read_document and
the stored-plan comparison so missing, malformed, or mismatched
s{scale}-plan.json failures produce the status "stored_plan_mismatch" instead of
"ordinary_receipt_missing"; preserve receipt-validation failures under their
existing status. Add "stored_plan_mismatch" to the allowed result-schema enum
used by progressive-provider-run-result.json.
In `@benchmarks/harness/graphforge_bench/progressive_run.py`:
- Line 560: Update ingest_benchexec_result() to compare the provider plan
identity profile_id with graphforge["profile_id"] before calling
assemble_rung_evidence() or creating rung, and reject mismatches explicitly;
only assemble evidence when both identifiers match.
In `@benchmarks/Makefile`:
- Line 57: Update the precondition in plan_provider_ladder so IMAGE_DIGEST is
not required during initial admission; require it only after the planner selects
a provider rung, while preserving validation of COMMIT, MAXIMUM_SCALE,
OUTPUT_DIR, and PLAN_OUT.

Closes #1032.
Adds the no-spend execution boundary needed before whole-attempt S18→S26 orchestration:
/workmount, drops to UID/GID 10001 with no-new-privileges, strips ambient credentials, and blocks volume-based Python module shadowing;This PR performs no provider calls and incurs no provider spend. It does not implement Fly/Pulumi ESC orchestration, typed spend authorization, sizing/capacity selection, ownership-ledger recovery, teardown inventory, or enable the live
progressive-ladderoperator. Therefore #900 remains open.Local validation:
No Docker/Podman daemon was available locally; CI builds the complete image without pushing or running provider operations.
