docs: correct legacy query-framing -> consonance (CLAUDE.md/STATE) + cross-thread quarantine guard

Advances the tracked VQL->VCL rename (#84). CLAUDE.md + 6a2/STATE reworded to the canonical consonance model already in README.adoc/EXPLAINME.adoc: VCL = propositions (DECLARE/ASSERT/RETRACT) + epistemic requests (INSPECT/VERIFY) over identity-consonance state, NOT a query language. Adds .machine_readable/bot_directives/cross-thread-quarantine.a2ml (spec-first grounding, provenance tags, quarantine of inbound cross-thread artifacts, anti-ReScript-migration rule). Origin: 2026-06-12 cross-thread contamination audit; no contaminated artifact had taken root, this hardens against recurrence.

 ## Project Overview
 
-VeriSimDB (Veridical Simulacrum Database) is a cross-system entity consistency engine with drift detection, self-normalisation, and formally verified queries. Each entity exists simultaneously across 8 modalities — the octad (Graph, Vector, Tensor, Semantic, Document, Temporal, Provenance, Spatial) — with drift detection and automatic consistency maintenance. Operates as standalone database OR heterogeneous federation coordinator over existing databases.
+VeriSimDB (Veridical Simulacrum Database) is a cross-system **identity-consonance** engine with drift detection, self-normalisation, and proof-bearing validation of **identity transitions**. Each entity is a *consonance subject* — one identity maintained across 8 modal witnesses, the octad (Graph, Vector, Tensor, Semantic, Document, Temporal, Provenance, Spatial) — with drift detection and automatic consonance maintenance. Operates as a standalone engine OR a heterogeneous federation coordinator over existing databases.
+
+> **Canonical framing — see `README.adoc` / `EXPLAINME.adoc` (authoritative).** VeriSimDB does *not* merely store or query records; it maintains identity consonance across modal witnesses. **VCL = VeriSim Consonance Language**: it expresses **propositions** (`DECLARE`/`ASSERT`/`RETRACT`) and **epistemic requests** (`INSPECT`/`VERIFY`), plus `MERGE`/`SPLIT`/`NORMALISE` — *not* SQL-style queries. "Query language" / "VQL" is a **deprecated misnomer**; any older query/CRUD wording below is legacy being retired (some code identifiers such as `QueryRouter` keep their names).
