Record of the design grill held on 2026-10-05. The owner (kayg) restarted infraternal as a new project. The old history is archived as kayg/infraternal-v0.

The decisions are in DECISIONS.md (commit d8f7a82). The overview is in docs/ARCHITECTURE.md. To change a decision, the owner must approve it. Record each change here and in DECISIONS.md.

Areas that were decided:

  • Product: all-in-one, self-hosted only, everything is a plugin, SSH first, performance first (1–6)
  • Architecture: one binary with two modes, a trusted server, an embedded agent as a subprocess, always relay, QUIC legs, a custom wire format, session shim, ghostty-web, plugins, one action with many adapters, lockstep upgrades, rootful and rootless agents, single node, platforms (7–20)
  • SSH and hosts: inventory sources, auth methods, passkey-sealed keys (21–23)
  • Identity and access: passkeys, recovery key, setup token, device keys, sessions, tag-scoped roles, OIDC (24–30)
  • Licensing and pricing: AGPL core and ee/, tiers, no paid work before users (31–33)
  • Slice order and the metrics plugin (34–35)
  • UI: floating sidebar with a tree, search capsule, mobile key bar (36–38)
  • Engineering: process, strictness, performance budgets, CI, repo (39–43)
  • Website (44–47)

Still open:

  • Prices for each tier (keep them out of the repo)
  • KCP for server ↔ agent (decide by benchmark)
  • Snapshot resume against state-diff resume (decide by benchmark)
  • S1 details (see the S1 grill issue)
