holger-server-ui — crate card

Reverse-engineered (from source — verify, don't trust the name)

• One-line pitch: Operator/admin UI for holger over the HolgerObject core API — a transport-agnostic view-model plus an optional egui (facett) presentation.
• Does: Two layers. data (default build, deps only on traits) drives the core HolgerObject API (satisfied by LocalHolger direct calls or RemoteHolger gRPC) and turns each response into a plain view struct exposing state_json() — so the UI is headlessly testable with no display/server ("see-what-the-user-sees as data"). app (behind the gui feature) is the egui + facett presentation with one blocking core call per action. Also demo (gui, real crates.io packages into a dev store + a robot walk) and operator tool panes: #1 holger-ds bench, #2 migrate/suck (agent connectors), #3 warehouse-backed security scan (modgunn), #5 airgap populate.
• Key deps: traits (always); under gui: eframe/egui/facett/facett-helix, server-lib, bench-scenarios[served], agent-lib, world-connector, znippy-rust-repo, modgunn[scan,warehouse], image. holger-airgap always. Robot tests use nornir-robotui + egui_kittest.
• Shape: both — lib (data/app/demo) + holger-server-ui bin (required-features=["gui"]). Package and all four bins were renamed from holger-ui* → holger-server-ui* on 2026-08-01, so the name says WHICH component the UI drives; the published holger-ui 0.1.4 on crates.io is a dead end (0 reverse deps, left unyanked). ~5 source files.
• Observed role in the workspace: The GUI front door for operators; aggregates the server + agent + bench + airgap + security tools into one pane. Default (non-gui) build is the fast headless test surface.

• Why it exists (vs the obvious alternative):
• Hard constraint (airgap / no-C-deps / no-FFI / pure-Rust / etc.):
• Release cadence & independence (rides a parent? own repo someday?):
• Status (production / prototype / experimental / stubbed):
• Must-NOT-change invariant:
• Biggest known gap or TODO:
• Anything a newcomer would get wrong about it:
