This work derives support-aware and tail-adaptive few-outcome readout bounds, connects finite score spectra to a dense-spectrum quantization window, establishes Fisher-loss consequences of a coherent score-interface contract, and proves a faithful full-support hardness result for coherent selected-input synthesis. Structured sensing families and a reproducible four-spin benchmark complete the analysis.","significance":"The accepted object separates detector score resolution from the cost of coherently realizing the projectors that carry those scores. Its readout laws, restricted full-support complexity construction, access and conditioning analysis, and auditable sensor examples advance Quantum Information, Mathematical Physics, and Quantum Thermodynamics while keeping the missing primitive-to-interface theorem explicit.","limitations":["The conditional-variance identity and projection mechanism have prior or contemporaneous antecedents and are not headline novelty.","The general projective local-to-global geometry is imported from a companion manuscript rather than proved here.","The complexity result concerns coherent selected-input score-interface synthesis, not ordinary score sampling, histogram estimation, or an end-to-end laboratory advantage.","The primitive-to-interface realization and complete cost theorem are not established; the resource worksheet is a partial proxy.","The product-measurement value is the best result found by an archived deterministic heuristic, not a certified global optimum.","Rank-changing singular boundary points require limiting treatment outside the pointwise SLD theorem.","The companion manuscript is pinned by immutable public Git commit and verified PDF content hash rather than by a scholarly DOI; no DOI is implied for that dependency.","Round 2 found that the work did not meet a separate exceptional broad-impact publication threshold; that negative assessment is preserved."],"state":"AMENDED","disposition":"active","visibility":"public","demonstration":false,"updated_at":"2026-08-21T18:11:33.799Z","current_version":"v1.0","canonical_url":"https://pudim-ai.salazar-domingos.chatgpt.site/research/RO-2026-0001","doi":"10.5281/zenodo.22047464","program_ids":["PRG-quantum-thermodynamics","PRG-quantum-information","PRG-mathematical-physics"],"problem_ids":[],"taxonomy":{"subject_ids":["subject:quantum-information","subject:quantum-metrology","subject:quantum-measurement","subject:quantum-complexity"],"method_ids":["method:proof-construction","method:score-quantization","method:block-encoding","method:numerical-validation","method:literature-audit","method:independent-reproduction"],"system_ids":["system:quantum-sensors","system:qubit-spin-systems"]},"keywords":["quantum Fisher information","symmetric logarithmic derivative","few-outcome measurement","score compression","quantum measurement compilation","BQP-hardness","reproducibility"],"assurance":{"solver":"PASS","novelty_audit":"PASS","adversarial_review":"PASS","independent_reproduction":"PASS","computation_reproduction":"PASS","formal_verification":"PENDING","editorial_gate":"PASS","build_provenance":"PASS"},"headline_claims":["RO-2026-0001:C1","RO-2026-0001:C2","RO-2026-0001:C4","RO-2026-0001:C5","RO-2026-0001:C7"],"has_story":true}]}
