znetsixe 5ae8788fd7 wiki: crisp overhaul — no decoration emoji, all 9 master pages refactored

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).

FlowFuse `ui-button` Manual (EVOLV Reference)

Note

Reference page. Maintained for context; not regenerated by code. See Home for current top-level navigation.

Source: https://dashboard.flowfuse.com/nodes/widgets/ui-button.html

Purpose

Clickable button that sends a message on user interaction.

Properties

Property	Type	Dynamic	Notes
`group`	ref	No	Parent ui-group
`width`	int	No	Columns
`height`	int	No	Row units
`label`	string	Yes	Button text
`icon`	string	Yes	Material Design icon name (no `mdi-` prefix)
`iconPosition`	string	Yes	`"left"` or `"right"`
`buttonColor`	string	Yes	Background color
`textColor`	string	Yes	Label color (auto-calculated if omitted)
`iconColor`	string	Yes	Icon color (matches text if omitted)
`tooltip`	string	No	Hover tooltip
`order`	int	No	Position in group
`emulateClick`	bool	No	Trigger click on any received msg

Events

Event	Enabled By	Output
Click	`onclick: true`	`msg.payload` = configured value
Pointer Down	`onpointerdown: true`	`msg.payload` + `msg._event` with timestamp
Pointer Up	`onpointerup: true`	`msg.payload` + `msg._event` with timestamp

Hold duration = pointerup._event.timestamp - pointerdown._event.timestamp.

Input

msg.payload — sets button payload value. With emulateClick: true, any input msg triggers a click.

msg.enabled — true / false to enable/disable the button.

Dynamic Properties (`msg.ui_update`)

msg.ui_update = {
  label: "Stop",
  icon: "stop",
  iconPosition: "left",
  buttonColor: "#f44336",
  textColor: "#ffffff",
  iconColor: "#ffffff",
  class: "my-btn-class"
};

EVOLV Key Rules

Use buttons for operator actions (start/stop pump, acknowledge alarm).
Set emulateClick: false (default) — don't auto-trigger on incoming messages.
For toggle buttons, update label/color dynamically via msg.ui_update from downstream logic.
Pair with confirmation dialog (ui-notification or ui-template) for destructive actions.
Standard sizing: width: 2, height: 1 for inline; width: 4, height: 1 for full-width in 4-col group.
