Remove legacy Data Machine Docs Agent bundles

 The consumer workflow supports separate lanes for technical docs, user docs, and live skills maintenance. Use `audience: skills` with skills/package writable paths instead of broad docs paths.
 
+The canonical execution architecture consists of exactly five native Agents API packages: technical bootstrap, technical maintenance, user bootstrap, user maintenance, and skills maintenance. Each `.agent.json` package is the sole executable instruction authority for its lane; `maintain-docs.yml` selects one immutable package without a separate manifest, flow, pipeline, or memory envelope.

 Schedule skills upkeep separately from docs upkeep. The skills lane should use a dedicated branch such as `docs-agent/skills-upkeep`, skill/package writable paths, verification commands, and drift checks through the portable recipe.
 
 When validation setup, verification commands, or drift checks are needed, pass them through the reusable workflow inputs above. `validation_dependencies` is an optional caller-owned command that runs before verification during a live execution. The reusable workflow includes those executable inputs in the portable recipe and keeps the target repository as the writable Docs Agent workspace.

 Native package selection is expressed through recipe `docsAgent.externalPackageSource`. Workspace boundaries are expressed through recipe `runner` fields so agents remain workspace editors while caller-owned execution handles sandboxing and publication handoff.

 ## Native Packages
 
-Docs Agent ships standalone native Agents API packages selected by the reusable workflow:
+Docs Agent has one canonical architecture: five standalone native Agents API packages selected by the reusable workflow:
 
 - `bundles/technical-docs-agent/native/technical-docs-bootstrap-agent.agent.json`
 - `bundles/technical-docs-agent/native/technical-docs-maintenance-agent.agent.json`
 - `bundles/user-docs-agent/native/user-docs-bootstrap-agent.agent.json`
 - `bundles/user-docs-agent/native/user-docs-maintenance-agent.agent.json`
 - `bundles/skills-agent/native/skills-maintenance-agent.agent.json`
 
-The reusable workflow maps `audience` and `run_kind` to exactly one package and its canonical agent slug. Every descriptor uses the package-source revision `7b2df969c34de112ec7ad13189ba94226a7f76f3`, independently of the revision that invokes the reusable workflow, and supplies a byte-level `sha256-bytes-v1` digest.
+These five `.agent.json` files are the complete executable package surface. Each package is the sole executable instruction authority for its lane. The reusable workflow maps `audience` and `run_kind` to exactly one package and its canonical agent slug; it does not select a separate manifest, flow, pipeline, or memory envelope.

 Package updates advance the package-source revision and all five declared digests atomically. The immutable-source validator reads each package blob from that Git revision, recomputes its digest and canonical slug, and rejects a descriptor that does not match those historical bytes.
 
-Each lane also ships native Agents API runtime packages for direct import through `wp_agent_import_runtime_bundles()`: technical docs bootstrap and maintenance, user docs bootstrap and maintenance, and skills maintenance. These packages retain the same source-grounded workspace-only editing boundary and required workspace-write gate as their corresponding bundle lanes.
+All five packages support direct import through `wp_agent_import_runtime_bundles()` and retain the source-grounded workspace-only editing boundary and required workspace-write gate.

+### Compatibility Impact

+Direct consumers of the removed legacy `manifest.json`, `flows/`, `pipelines/`, or memory envelopes must migrate to the corresponding native `.agent.json` package listed above. Consumers of `maintain-docs.yml` already use these native packages and require no workflow migration.

 It imports every native package through `wp_agent_import_runtime_bundles()`, verifies registration and preserved write-gate defaults, and invokes the default native chat handler far enough to resolve each registered agent. It intentionally fails when `AGENTS_API_DIR` is unavailable rather than treating an unexecuted importer as a passing test. It does not execute a model turn because the packages intentionally leave provider/model selection to the caller.
