Namespace and URI publications

Agent Volumes publishes owned namespaces and URI identifiers under agentvolumes.org so implementers can cite, dereference, and validate the identifiers used by the specification and its companion artifacts. The repository remains authoritative. The public site is a publication layer for the canonical specification, schemas, OpenAPI contract, conformance fixtures, and decision records. Semantic identifier routes such as https://agentvolumes.org/build/manual/v0.1, https://agentvolumes.org/predicates/external-dependency-declarations/v0.1, https://agentvolumes.org/ns/spdx/external-dependency-declarations/v0.1#, and https://agentvolumes.org/problems/<slug> resolve to stable landing pages for the identifier itself. The SPDX JSON-LD context also has a stable canonical remote context URL at https://agentvolumes.org/contexts/spdx-external-dependency-declarations-v0.1.jsonld. Those stable routes link back to this release archive and to canonical repository artifacts. JSON Schema $id URLs remain release-scoped under https://agentvolumes.org/spec/<version>/schemas/<artifact>.

Release evidence workflow

For each release candidate or stable release:

Install repository and site dependencies with bun install and (cd site && bun install).
Refresh the Mintlify OpenAPI publication artifact with bun run build:site:openapi -- 0.1.0-rc.1.
Validate the public site with bun run lint:site.
Run the canonical gates: bun run lint:openapi and bun run validate:artifacts.
Create a release evidence issue from .github/ISSUE_TEMPLATE/release-evidence.md.
Fill the Namespace and URI publication evidence table with the public URL, source artifact, and route or immutability check evidence for each Issue #29 row.
