Nectar is the preview substrate on the mesh — the tool an agent calls the moment it declares work review-ready.
Reviewing agent work means testing it, fast. Nectar packages a testable build of the branch, serves it on the mesh, and hands back a small, stable reference. The review desk renders whatever the reference points at — web preview, desktop testpack, streamed iOS simulator. One command, and the work is tasteable from any device.
# at review-ready, on the machine where the agent runs $ nectar publish --json $ nectar expose --to site # when a preview needs to leave the tailnet → https://<env>.nctr.site (gated, TTL'd, torn down on expiry)
The branch dev server, named on the mesh. Embeds straight into the review desk's Test tab.
A signed, immutable testpack — one-click openable, sha256-verified before it ever launches.
A simulator build plus an interactive streamed simulator you can tap and type in, from a browser.
A provisioned shell, or a seeded environment with smoke evidence — no surface, just proof.
Envs live and die on the machine that published them. Nothing is forever; garbage collection reaps on schedule.
Previews are private by default. Public exposure is an explicit, gated, per-preview escalation — never the default.
