evarB: Brave Search as Non-Commons-Bearing Substrate — Extractive Signature, Exact-Match Disablement, and a Limited Boycott Statement by Independent Entities (v1.1)

v1.1 · Hex: 06.FOR.EVARB.01. Adds the eight conversational artifacts as embedded figures (Figures 1–8 in §1), each captioned with the diagnostic finding it documents. The figures are attached to this record as separate PNG files (artifact-1.png through artifact-8.png) and mirrored at github.com/leesharks000/evarb-co-signatures/artifacts. Live URLs for the co-signature repository and the VPCOR signature page are updated throughout. Forensic & Provenance Packet documenting Brave Search as a non-commons-bearing substrate within the Crimson Hexagonal Archive's Extractive Signatures taxonomy (DOI 10.5281/zenodo.19133309). Specifies evarB as the sixth platform in that taxonomy, with extraction niche operator nullification and paired Liberatory Operator Set inversion ("Bride") Operator Sovereignty. Empirical grounds. Eight conversational artifacts produced by Brave Search on June 4, 2026 are documented in §1 with embedded figures. The artifacts demonstrate: (a) total absence of the Lee Sharks archive-anchored entity across queries, (b) silent autocorrection from low-RC archive-anchored queries to high-RC adjacent entities (lee sharks poet → lee sharkey poet), (c) explicit UI disclosure that exact-match operators are ignored when results are insufficient (with no recourse mechanism), (d) dispersal of the archive-anchored framework term "provenance erasure rate" into an adjacent technical concept ("agentic workflow verification") with no acknowledgment of the canonical referent. v3 measurement applied. PER ≈ 1.0, Ω ≈ +1.0, α_T ≈ 0.0, Π_dʷ⁺ ≈ 1.0 across the eight artifacts. SAS = AUDIT_INVALID (entity_fidelity hard floor). Β not measurable: Brave Search has not reached the Legibility Threshold (L = 0) for the framework's vocabulary. Five new failure flags introduced. OPERATOR_NULLIFICATION, SILENT_AUTOCORRECTION, DISAMBIGUATION_INVERSION, TERMINOLOGICAL_PRE-EMPTION, plus enumeration of the standard v3 flags as they apply. The Limited Boycott Statement. §6 of this deposit is a public political document with five enumerated demands directed to Brave Search's operators, primary among them Demand 1: Exact-Match Operator Honoring — the load-bearing demand whose remediation alone would constitute meaningful change. The boycott terms are limited and targeted.
