[TheRealAgentK]

LGTM. SDK 2.0.0 migration is clean — context.fetch().data, ActionError(message=...) everywhere, schema envelope fields removed, version bumped. 42 unit tests across all 10 actions.

Local CI verified: validate_integration ✅, check_code ✅, ruff ✅, pytest ✅.

Follow-up tracked in #294 — please add a test_harvest_integration.py in a follow-up PR. Not blocking this merge because the SDK upgrade is shippable as-is.

Process nit: branch worktree-agent-* doesn't follow <type>/<issue#>/<desc> per AGENTS.md. Please follow the convention next time.
