Summary

Root B (#8357) migrated ct_groupcompletion_checkpoint_fires_under_faithful_corpus_test into v1.tests.claim.checkpoint_identity_keying_witness_test but left its language_source_scaffold_index row behind, so compiler_tests_rust_blobs_are_all_rostered counted 41 rostered ct_ blobs against 40 live declarations.

The two runner_slot_provision_witness_test reconcile failures were already repaired on main by #8401. This PR closes the remaining scaffold witness and includes a one-line fix for host_network_diagnosis matching std.upsert_decision.Absent on a NetplanConfigFile? (runtime non-exhaustive match on none).

Merged latest main (inference spring clean #8389) to pick up reconcile cost reductions before re-running witnesses.

Test plan

  • Verified roster parity locally: 40 declared ct_ fns == 40 rostered blobs.
  • CI witnesses workflow on this PR.

Root B moved ct_groupcompletion_checkpoint_fires_under_faithful_corpus_test into v1.tests.claim.checkpoint_identity_keying_witness_test but left its language_source_scaffold_index row behind, so compiler_tests_rust_blobs_are_all_rostered counted 41 rostered blobs against 40 live ct_ declarations.

The fold matched std.upsert_decision.Absent on a NetplanConfigFile? input, so none/null fell through and host_network_diagnosis_witnesses errored at runtime with a non-exhaustive pattern match.
