test: executable C-01/C-02 semantic ring oracle and negative controls

[AdaWorldAPI]

Purpose: the thought address is the witness coordinate; the version witnesses the change

This PR makes the C-01/C-02 ring falsifier executable without inventing a second witness identity. The manually bound four SPO facts use fixed symbolic referent/claim identities. A recorded claim at the existing symbolic address corefers(last_sentence.key,first_sentence.key) first becomes visible in the sealed revision (symbolic-ring, main, v17).

• C-02 at v16: identities stay distinct; four sentence edges do not close the ring.
• C-01 at v17: the same identities plus the versioned claim make the ring close for every rotation.
• C-02 re-read at v17: closes as well, with no new entity/claim identity minted by the query.
• Wrong branch, dataset or older version cannot witness the change. The referent identities never depend on reading order.

The version witnesses that the claim was present in that sealed history. Its original independent source roots remain separate receipt metadata for evidential independence, NAL revision and appropriate authorization/certification. A version alone does not establish the external truth of coreference, and thought-slot reuse cannot substitute for a sealed historical reference.

Changes

• Manually bound C-01/C-02 gold with one stable claim address, version-stamped identity assertion, pinned read heads and source roots in the revision receipt.
• Test-only Python reference oracle. The old external_identity_witness field in docs(research): versioned semantic candidate resolution across 64 thoughts #1604's preregistered fixture is not used as a second identity or as the admission authority; the original JSON remains untouched for traceability.
• 15 local adversarial tests (historical visibility, rotations, wrong version/dataset/branch, root-label spoofing, missing relation, predicate mutation, wrong address, unregistered rotation, malformed ref, etc).
• Dedicated path-scoped GitHub Actions check, with no Rust production path or CE64 ABI changes.

Verification

GitHub Actions Semantic ring reference oracle passed on head af058caf (run 39147776033).

Boundaries and next integration gate

This is an independent manually bound oracle, not a parser, real Lance commit, R2IL relational join, or source authentication system. The version IDs are synthetic. The C-01/C-02 results are reference expectations; no production coreference/reasoning ability is claimed.

Next step: connect pinned DeepNSM/UD bindings and versioned thought writes to the existing mask/R2IL lowering, checking that the same claim address and pinned revision produce oracle-equivalent results, including refusal of false identity and historical leakage.
