- **Sessions (#412):** `end_reason` and `time_claimed`, with migration
`0026_session_end_reason` (two nullable columns, readable by the release
it replaces). `POST /session/:id/state` takes an optional `endReason`,
and a run stopped before it went live can now go from `starting` to
`ended`.
- **Installer (#411):**
- `bash <(curl -fsSL https://api.nestri.io/install.sh) -u` updates a
host; `-h` prints help; a plain token installs.
- When the script is not root, it asks sudo itself.
- The installed host agent version is unchanged (0.2.18).
**Ships before host agent 0.2.19**, which sends `endReason` and the new
transition.
Cut from prod with dev's files, so squash histories cannot conflict; the
tree is identical to dev.
A host holds only so many runs at once, and until now every waiting run
was handed to it regardless; the ones it could not hold failed there.
The host now says on its heartbeat how many runs it holds, and is handed
only as many waiting runs as it has free. The rest wait in line: paid
runs before free-weekend runs, then first come first served. Reading a
waiting run returns its place in line, and says when a paid run that
asked later has gone ahead, so a free player is never reordered quietly.
A waiting run nobody has asked after for a minute was abandoned, and
leaves the line rather than holding up everyone behind it. A host that
does not report its slots is handed every run, as before.
