Harness foundation: INTENT, ADR-001, architecture, prototype adoption
- INTENT.md: three-layer model (blueprint/instance/harness), single
shared runtime, never-become boundaries
- ADR-001 (accepted): DEC-2026-002 resolution — one harness repo for
all projects; instances are declarative state in consuming repos
- docs/architecture.md: components, contracts (manifest, tool
profiles, completion events, credential lanes), deployment shape
- agent_harness/: executor-worker prototype adopted and renamed
(6/6 tests green); HARNESS-WP-0001 initial workplan (7 tasks)
