Agentic Sandbox v2026.6.16

Released: 2026-06-17 Tag: `v2026.6.16` Previous: `v2026.6.15` Compare: `v2026.6.15...v2026.6.16`

What This Release Is

v2026.6.16 is a direct-delivery CalVer release-flow cut for two release-ready fixes: GitHub release checksum mirroring and host-runtime visibility in the v2 admin instance list.

Highlights

  • The GitHub release mirror now includes the aggregate `SHA256SUMS` manifest,

matching the checksum surface published by the primary release flow.

  • Host-runtime instances registered through the executor registry now appear in

`GET /api/v2/admin/instances` even when they have no libvirt or Docker object.

  • Host-backed admin entries report `runtime: "host"` and preserve registered

loadout metadata for dashboard and operator clients.

Operator Notes

  • Use `v2026.6.16` for the release-flow cut that includes the GitHub checksum

mirror fix and the host-runtime admin listing fix.

  • Host-runtime lifecycle operations still require the configured durable host

supervisor path; this release fixes listing visibility for registered host contexts.
