v0.1.3

Pre-1.0 PATCH release clarifying governing-source records without changing workflow requirements.

• Replaced the general-purpose PROVENANCE.md with the purpose-specific GOVERNING-SOURCES.md. The new registry preserves all five live Standards Templates governing-source dependencies through immutable source pins and template editions.
• Governing-source links now use stable Standards Templates template IDs. The former project-repository-responsibility registry anchor is now project-repository-model.
• Repo-template alignment and history are no longer maintained as permanent provenance state. Creation authority lives in AGENTS.md, and reconciliation guidance lives in MAINTAINING.md.

Governing-source pins were not advanced: all five remain at Standards Templates revision df73ad31cdbb15210ad9670d669d3c567a79a1d3 and edition 1.0.

Workflow requirement meaning and strength did not change. Consumer authority semantics did not change: actual project authority controls instantiated workflows, and source references do not adopt standards for consumers. Previously instantiated handoffs remain valid against their recorded immutable Agent Workflows revision.

Consumers directly referencing library paths or fragments should account for PROVENANCE.md → GOVERNING-SOURCES.md and #project-repository-responsibility → #project-repository-model when deliberately updating to this release. Existing immutable references remain valid; no automatic consumer update is implied.
