A.19.SelectorMechanism:11.1 - SoTA alignment map (normative)

SoTA practice pointer, post‑2015+	Primary source examples, post‑2015+	Where it connects to SelectorMechanism	Adoption status
Treat the Pareto set or declared selected set as a first-class output under multi-criteria partial orders	Quality Diversity as a decision framing, e.g., Pugh et al. 2016; Vassiliades et al. 2018	Expressed as set‑return default and explicit set-return criteria; method details live in specializations and wiring	Adapt
Use archive-based retained sets where diversity is part of the result, but do not silently promote it to dominance	Modern QD and archive practices post‑2015, including map-elites descendants and archive insertion policies	Expressed as policy‑bound criteria and report‑only telemetry unless explicitly promoted	Adapt
Pair environments and methods in open-ended or co-evolutionary settings without breaking kernel semantics	Open-ended environment-method pairing, e.g., Wang et al. 2019 and successors	Expressed as candidate and criteria structuring plus admissible specializations; kernel unchanged	Adapt
Include an explicit abstain or reject option under uncertainty rather than forcing a decision	Selective prediction and rejection-option practice, e.g., Geifman and El‑Yaniv 2017; follow-on selective nets	Expressed as tri-state `SelectEligibility` with fail-closed discipline	Adopt
Keep architecture commitments traceable to one governing pattern	ISO/IEC/IEEE 42010:2022 architecture description discipline	Expressed as explicit governing-pattern assignment and Tell+Cite stubs elsewhere	Adopt

Notes per row (1–2 sentences; why to adopt, adapt, or reject):

Selected-set-as-output (QD framing): adopt the decision framing (declared selected set as a first-class result) while keeping concrete QD or retained-set algorithms out of the kernel; they belong in G.2 packs and wiring modules, preserving evolvability.
Archive retained sets (diversity as result): adapt archive thinking by keeping diversity and illumination signals report‑only unless an explicit CAL policy promotes them to dominance; this prevents silent scalarization and preserves governing-pattern defaults (typically G.5 and CAL).
Open‑ended environment–method pairing: keep the kernel unchanged; open‑ended pairing is expressed by shaping candidates and criteria (and, when needed, admissible specializations ⊑ and ⊑⁺) with explicit edition pins and transfer and validity rules in planned baseline, not by mutating Select.
Reject or abstain under uncertainty: adopt the rejection‑option stance as a tri‑state guard with fail‑closed semantics; explicit abstain is preferable to forced choice under missing admissibility and evidence.
Governing-pattern architecture discipline: adopt governing-pattern + Tell‑and‑Cite to keep the spec teachable and reviewable; this directly reduces drift and “second centers of gravity”.
