#Content

Informative; manager‑first (E.7/E.8 Tell‑Show‑Show).

Show‑A - SRE capacity plan (selector returns a set). Frame. We must raise service commitment headroom for Q4 without breaking latency SLOs. Portfolio. {cache‑expansion, read‑replicas, query‑shaping, circuit‑breaker tuning, schema‑denorm}. Glossary in action. U = latency@p95 & error‑rate, C = budget ≤ $X, risk ≤ R, N = dissimilarity to current playbook, Diversity_P = adds a previously empty niche in our archive (e.g., “shifts load to edge”). E/E‑LOG starts Explore‑heavy, flips Exploit‑heavy once ≥ K distinct niches are lit. (Publish UTS row + parity pins; illumination stays report‑only telemetry.)

Show‑B - Policy search with QD archive (MAP‑Elites‑class). Frame. Robotics team explores gaits that trade stability vs energy use. Glossary in action. CharacteristicSpace = {step‑frequency, lateral‑stability}, ArchiveConfig = CVT grid, N from descriptor distance, U = task reward, Diversity_P = coverage gain; PortfolioMode=Archive. Families include MAP‑Elites (2015), CMA‑ME/MAE (2020–), Differentiable QD/MEGA (2022–), QDax (2024); publish editions and policy‑ids; treat illumination as report‑only telemetry.

(Optional) Show‑C - OEE parity (POET/Enhanced‑POET). Co‑evolve {environment, method} portfolios; publish coverage/regret as telemetry metrics; pin TransferRulesRef.edition; return sets, not a single winner.

Show‑Epi - Evidence synthesis (U.Episteme). Frame. A living review compares rival causal identification methods (e.g., IV vs. DiD vs. RCT‑adjacent surrogates) across policy domains. Glossary in action. U = external‑validity gain @ F/G‑declared lanes, C = ethics & data‑licence constraints, N = dissimilarity in **ClaimGraph** transformations, D_P = coverage of identification niches in the archive. ReferencePlane = episteme. Illumination/coverage stays report‑only telemetry; selection returns a portfolio of methods per niche. (Publish UTS rows; cite Bridges + CL for cross‑domain reuse; edition‑pin Descriptor/Distance defs where QD applies.)
