Source-tree mirror of EVOLV.wiki.git refactor (27a42ee on wiki.git): - 7 master pages rewritten with clean design (Home, Architecture, Topology-Patterns, Topic-Conventions, Telemetry, Getting-Started, Glossary). Tables and Mermaid for visuals, gitea alert callouts for warnings, shields badges for metadata only. No emoji as decoration. - Archive.md becomes a removal-changelog pointing readers to git history and to the successor pages. - _Sidebar.md updated to navigate the new flat-name layout. - Concept / finding / manual pages: uniform mini-header (badges + "reference page" callout) added without rewriting domain content. - Every internal link now uses the flat naming that resolves on the live gitea wiki (Concept-ASM-Models, Finding-BEP-..., etc.). On wiki.git: 29 Archive-* pages hard-deleted (the git history preserves them; Archive.md documents the removal). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Pump Switching Stability
Concern
Frequent pump on/off cycling causes mechanical wear, water hammer, and process disturbance.
Test Method
Sweep demand from 5% to 95% in 2% steps, count combination changes. Repeat in reverse to check for hysteresis.
Results — Mixed Station (2x H05K + 1x C5)
Rising 5→95%: 1 switch at 27% (H05K-1+C5 → all 3) Falling 95→5%: 1 switch at 25% (all 3 → H05K-1+C5)
Same transition zone, no hysteresis.
Results — Equal Station (3x H05K)
Rising 5→95%: 2 switches
- 19%: 1 pump → 2 pumps
- 37%: 2 pumps → 3 pumps
Clean monotonic transitions, no flickering.
Why It's Stable
The marginal-cost refinement only adjusts flow distribution WITHIN a combination — it never changes which pumps are selected. Combination selection is driven by total power comparison, which changes smoothly with demand.
