Changelog · Release notes
Agent Orchestrator (Send-To / atm-core)
As an agent orchestrator wiring atm-core Send-To, I want a documented Wyvern picker contract with CI that catches wire drift, so optional native pickers stay aligned with atm-core releases.
v0.7.0 ships the atm-pick-member wizard example — the canonical HTML/JS page atm-core vendors for optional Wyvern pickers — plus CI that pins atm-core v1.6.1 fixtures, hash-checks contract bytes, runs atm-core Send-To surface tests, and probes a real wyvern build. The CLI surface is unchanged: PickerInput still travels as wizard config, and callers read WizardResult.data as PickerOutput.
Maintainer / release engineer
As a maintainer, I want sc-lint boundary enforcement and kit-managed releases to stay green, so quality gates match the rest of the org.
This minor release lands sc-lint 0.5.0 across Wyvern boundaries and CI (including consumer bootstrap lanes and extended analyzers) and migrates the binary logger to sc-observability v2. No breaking changes to dialog JSON schemas or host IPC for integrators on 0.6.x.
What's Next
Follow kit release flow on main after merge: release-candidate-v0.7.0 → preflight → production dispatch. Advance release/atm-core-send-to-pin.toml together with any PickerInput/PickerOutput schema change.
