BH-VP1 supplies a public-data diagnostic surface for the compact-object sector of the covariant CHC framework (CHC). It uses the official GWTC-3 Tests of General Relativity public posterior products, with the inspiral--merger--ringdown (IMR), updated ringdown, parametrized-deviation, and spin-induced quadrupole results treated as bounded public diagnostic surfaces. The archived manuscript remains authoritative for exact notation, equations, assumptions, and exclusions.

BH-VP1 is a bounded public posterior-comparison diagnostic for CHC-BH1/BH2. Its purpose is to test whether official public LVK/GWTC-3 Tests-of-GR posterior products can be read back as compact-object diagnostic surfaces. The diagnostic comparison does not re-run LVK inference, replace waveform pipelines, reinterpret the LVK likelihood, or infer a microscopic black-hole theorem. It also does not claim a GR violation from diagnostic stress rows.
The admissible interpretation is: quote BH-VP1 uses official public Tests-of-GR posterior diagnostic boards for IMR consistency, ringdown, parametrized deviations, and spin-induced quadrupole tests, with bounded CHC compact-object interpretation. quote
The forbidden readings are: compact-object theorem; black-hole interior closure; quantum-gravity solution; EHT/LVK pipeline replacement; return-kernel theorem closure; or microscopic entropy theorem.
The primary public source is the LVK GWTC-3 Tests of General Relativity posterior release. The public posterior products cover IMR consistency, Lorentz-invariance violation, parametrized tests of GR, an updated ringdown test, and spin-induced quadrupole moment tests [citation]. The LIGO DCC release for P2100456 and GWOSC public records identify the relevant Tests-of-GR source families, event metadata, and parameter-estimation products used for this diagnostic reading [citation]. The published GWTC-3 Tests-of-GR paper reports the corresponding GR-test suite and summarizes the standard interpretation that no evidence for deviations from GR was found [citation].

The VP1 companion record uses the following gate sequence.
- BH-R0: public-source identification. Required official public posterior source surfaces must be identifiable and tied to the declared diagnostic comparison. - BH-R1: posterior source summary. Public archive/HDF5 readability and parameter maps are recorded. - BH-R2: IMR consistency diagnostic board. IMR posterior coordinates are read back under the declared diagnostic rule. - BH-R3: ringdown diagnostic board. Updated ringdown posterior coordinates are read back under the declared diagnostic rule. - BH-R4: supporting parametrized and spin-induced quadrupole boards. Parametrized deformation and spin-quadrupole posterior surfaces are recorded as diagnostic/supporting boards. - BH-R5: interpretation boundary. All outputs remain diagnostic-only and non-claim boundaries are enforced.
The companion source summary identifies the public-source surfaces listed below and the source state summarized in Table reference. Multi-GB posterior surfaces remain external to the manuscript body; the companion statement identifies the public source metadata needed to interpret the bounded diagnostic. center 1.10

The diagnostic board labels are listed in Table reference. The IMR board passes the declared IMR consistency diagnostic. The updated ringdown, parametrized, and spin-induced quadrupole boards return diagnostic stress labels. These stress labels identify posterior-comparison sensitivity under the declared rule; they are not interpreted as GR-violation claims.

The spin-induced quadrupole diagnostic board contains 20 rows, of which 9 are diagnostic-stress rows under the declared diagnostic convention. The comparison treats dQuadMonS as a deviation parameter with GR reference value zero. This convention is only a diagnostic comparison rule and not an LVK reanalysis.
The final companion-record classification is
\boxed{\texttt{BH-VP1-TGR-DIAGNOSTIC-PARTIAL}}.The label is assigned because the public archive source gate passed, the IMR board received an assigned pass label, the updated ringdown and spin-induced quadrupole boards received assigned diagnostic labels, the parametrized board is present as a supporting stress surface, and the non-claim boundary is explicitly preserved.
This result extends BH-VP0's compact diagnostic surface by adding official GWTC-3 Tests-of-GR posterior products. It does not change BH1/BH2 into theorem-level compact-object papers.
A natural future candidate would be an O4a/GWTC-4 Tests-of-GR posterior diagnostic record. The GWTC-4.0 Tests-of-GR literature now includes the O4a overview/general-test, parameterized-test, and remnant-test papers [citation]. The associated public data-product surfaces for those three Tests-of-GR papers are also available [citation]. This BH--VP1 record nevertheless remains a GWTC-3 posterior-comparison diagnostic record, because the imported public object here is the official GWTC-3 Tests-of-GR posterior surface. The currently cited GWTC-4.0 parameter-estimation public release supplies parameter-estimation posterior samples and a catalog PE surface, not a replacement for the declared GWTC-3 TGR v2 posterior diagnostic lane [citation]. The existence of GWTC-4.0 TGR public source summaries does not by itself supply an adopted BH--VP1 object ledger or replace the declared GWTC-3 TGR v2 posterior diagnostic lane. Any GWTC-4 TGR data-product import would require a separately declared object ledger and classification boundary; it would not by itself upgrade BH1/BH2 to waveform-consistency closure, ringdown-residual closure, a GR-violation claim, or a compact-object theorem.
BH-VP1 supplies a bounded public diagnostic record for CHC-BH1/BH2. The public record identifies the official GWTC-3 Tests-of-GR posterior surfaces, assigns IMR, ringdown, parametrized, and spin-quadrupole diagnostic labels, and returns . The assigned status is a companion diagnostic source basis only. It is not an LVK/EHT pipeline replacement, not a GR-violation claim, not a compact-object theorem, and not a quantum-gravity solution.
