test-claim consolidation design: unified resolved-type claim system + one runner + migration/equivalence plan; no implementation before Mgr-C/parent gate

[briansrls]

Summary

Revised design (per Mgr-C gate feedback): test-claim consolidation as a dual-modality unified system, not Node-corpus-only laundering.

• UnifiedTestClaim coproduct: NodeCorpus { TestClaim + TestClaimEvalSubject + transport } | BoolWitness { entry, function, receipt } — discovered by resolved-type heads.
• Model-first: verification.dag lands BoolWitness arm first (load-bearing L2.5 gate before runner implementation).
• Bool semantics preserved: fn() -> Bool witnesses stay fn() -> Bool; no mandatory projection to TestClaimEvalSubject<Node>.
• One runner: run_unified_corpus_eval dispatches by modality; CorpusEvalReport tags NodeCorpusRun vs BoolWitnessRun (modality boundary not erased).
• v4_roster_pilot deletion gated on C9–C11: discovered BoolWitness set == roster, run-equivalence, perturb discrimination.

Test plan

• Design doc only; no code changes
• Revised per parent review msg_bb0de7b7 (witty-pike-248)

Addressed both findings in bc8dd2f follow-up:

1. BoolWitness registration arm — dropped receipt: BoolWitnessReceipt. Descriptor is now entry + function only, symmetric to NodeCorpus keeping execution artifacts off the claim row. Added explicit P2 registration-discipline paragraph after the coproduct block.

2. BoolWitnessReceipt naming — removed the undefined type entirely. §3.3 retitled to "Run receipts (modality-preserved; separate from registration)" with a registration vs execution table showing BoolWitnessRun as the Bool-modality run receipt (symmetric to NodeCorpusRun wrapping TestClaimRun). §3.2 substrate delta updated: verification.dag lands descriptor types only; UnifiedClaimRun / CorpusEvalReport land on the eval/runner side.

Phase 1 implementers now have one receipt story: descriptors on UnifiedTestClaim, execution on UnifiedClaimRun.
