A6 Composition Layer v0.1.1: Hybrid / Federated Anchor Composition Profile for c = a + b

This release publishes A6 Composition Layer v0.1.1, a boundary profile for hybrid and federated anchor composition in the c = a + b framework.

The profile formalizes A6 as an anchor-composition state over A0–A5, not as a merged super-anchor. It defines mandatory maps for participating anchors, standing, authority, memory compartments, sensors, jurisdiction, Experience Artifacts, revocation, exit, split handling, and resource/custodian responsibility.

The release distinguishes A6-EXIT from A6-SPLIT:

A6-EXIT = revoke-and-continue.
A6-SPLIT = freeze-and-escalate.

The package also includes Anchor Class Boundaries v0.2.1, which provides the protocol-facing taxonomy for anchor classes in c = a + b and points to the A6 Composition Layer for detailed A6 behavior.

This work is a protocol and research artifact. It does not create legal personhood, public authority, product certification, public-law activation, or post-anchor sovereignty. Applicable law remains external to the protocol.
