… Finish-Gate, Data Viz) (msitarzewski#742) Lands four gated single-agent contributions via a consolidated branch (avoids the README-conflict cascade of parallel fork PRs). Each passed the full gate: lint 0/0, originality 0.0%, canonical structure, and a manual conceptual-dupe check against the existing roster. - Rust Refactoring Specialist (engineering) — behavior-aware, evidence-based Rust refactoring across crates/traits/modules. (msitarzewski#741, @TanasiDesigns) - LLM Post-Training Engineer (engineering) — SFT/DPO/GRPO/RLVR experiment gating, checkpoint integrity, failure classification. Distinct sub-specialty from AI Engineer. (msitarzewski#740, @kaining-never-stop) - UI Finish-Gate Reviewer (design) — anti-generic UI finish gate; catches interchangeable UI before ship via evidence + a written design contract. Distinct from the testing-division Reality Checker. (msitarzewski#739, @samuelbushi) - Data Visualization Engineer (engineering) — chart-type selection, perceptually honest encodings, colorblind-safe palettes, performant D3/Vega. (msitarzewski#729, @Hotragn) README roster rows added for all four; Hermes generated count 265 -> 269. All guards green (divisions/tools/runbooks/hermes-plugin/lint).

What does this PR do?
Adds a Data Visualization Engineer agent to the engineering division. Charting/visualization engineering is uncovered: the Frontend Developer has zero charting content, and the Visual Storyteller (design) is about narrative, not encoding accuracy. This agent covers chart-type selection driven by the data and the question (comparison/trend/distribution/correlation/part-to-whole), perceptual accuracy (position/length over angle/area, honest baselines, no dual-axis trickery), colorblind-safe categorical/sequential/diverging palettes matched to data structure, chartjunk elimination, accessibility (keyboard nav, screen-reader summaries), and rendering large datasets performantly (the SVG → canvas → WebGL crossover, plus hexbin/LTTB aggregation). Verified 0.0% originality against the roster.
