9	9	* **CLAIM_CLUSTER**
10	10	** ``ClusterID`` (PK), ``EmbeddingVectorRef``, ``Theme``
11	11	** Groups related claims into topical clusters.
12		-** One Cluster has many Claims.
13		-** A Claim belongs to exactly one primary cluster.
14	14
15	15	* **CLAIM / CLAIM_VERSION**
16	16	** ``CLAIM`` is the long‑lived anchor for a real‑world claim.
17	17	** ``CLAIM_VERSION`` is an immutable snapshot of wording + basic metadata.
18		-** **Note:** Verdicts are **NEVER** attached directly to a Claim. They are attached to Scenarios.
	16	+** Verdicts are **NOT** attached to ClaimVersion but to Scenario.
19	19
20	20	* **SCENARIO / SCENARIO_VERSION**
21	21	** ``SCENARIO`` represents a stable interpretive context for a claim.
22	22	** ``SCENARIO_VERSION`` is an immutable snapshot of that context (definitions, assumptions, boundaries).
23		-** A single Claim may have multiple Scenarios.
	21	+** Verdicts are attached to SCENARIO, with verdict history in VERDICT_VERSION.
24	24
25	25	* **EVIDENCE / EVIDENCE_VERSION**
26	26	** ``EVIDENCE`` is the logical source (report, article, dataset…).
27		-** ``EVIDENCE_VERSION`` is the extracted/processed snapshot (summary, reliability score, extraction method).
	25	+** ``EVIDENCE_VERSION`` is the extracted/processed snapshot (summary, reliability, etc.).
28	28
29	29	* **VERDICT / VERDICT_VERSION**
30		-** ``VERDICT`` represents the assertion "this claim is assessed **under this specific scenario**."
31		-** ``VERDICT_VERSION`` is an immutable snapshot of the evaluation (likelihood, confidence, reasoning, timestamp).
32		-** **Cardinality:** 1 Scenario has 1 active Verdict (but many Verdict versions over time). Therefore, 1 Claim has N Verdicts.
	28	+** ``VERDICT`` represents “this scenario is evaluated for this claim.”
	29	+** ``VERDICT_VERSION`` is an immutable snapshot of a concrete evaluation (likelihood, confidence, reasoning, timestamp).

34	34	* **SCENARIO_EVIDENCE_VERSION_LINK**
35	35	** Connects ``ScenarioVersion`` ↔ ``EvidenceVersion`` (many‑to‑many).
36		-** Fields: ``LinkID``, ``Relevance``, ``Direction`` (SUPPORTS / CONTRADICTS / NEUTRAL / MIXED).
37		-** **Rule:** The link always targets specific **VERSIONS** of entities, never the base tables, to ensure auditability.
	33	+** Fields: Relevance, Direction (SUPPORTS / CONTRADICTS / NEUTRAL).
	34	+** **Rule:** The link always targets VERSIONED entities, never the base tables.
