holger — crate card

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

• One-line pitch: The holger-server binary — starts the gRPC/HTTP server from a RON config and manages its systemd lifecycle + a couple of operator tool verbs.
• Does: clap CLI over holger-server-lib. Verbs include start --config (read RON, wire_holger, serve), dev-pair (generate + start the dev /cache + /sparring registry nornir embeds), the holger-ds artifact-delivery benchmark (via bench-scenarios served), and airgap populate (via holger-airgap). systemd add/update/delete/status is delegated to the Skíðblaðnir engine (holger owns the service spec + paths, never hand-rolls systemd).
• Key deps: server-lib (features=["sign"] → provenance verification), skidbladnir (systemd lifecycle, default-features off), bench-scenarios (served), holger-airgap, clap, tokio, ctrlc, env_logger.
• Shape: bin (holger-server), single main.rs.
• Observed role in the workspace: The production server entrypoint. Deployed via systemd; dev-pair is what nornir stands up as its embedded registry.

• Primary consumer(s):
• 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:
