feature: agent workflow and supporting capability corpus exists

[tucktuck101]

Parent PRD

#602

Milestone

Knowledge crate shipped

Outcome

Agent, workflow, Git, project and supporting product capabilities are documented as atomic, traceable nodes.

Acceptance criteria

• All 70 planned documents in this feature have exactly one child task each and every required task is complete or explicitly removed from scope by an approved PRD change.
• Every node passes corpus schema/graph/provenance validation and uses the assigned template.
• Every node names concrete source start points and records evidence from current code/tests/specs/decisions/history appropriate to its claims.
• The feature's source-inventory slice has no unclassified in-scope item; exclusions are explicit and reasoned.
• No broad overview page duplicates canonical claims owned by atomic child nodes; navigation links instead.
• An independent developer/agent can answer a representative question in this feature area by traversing corpus nodes to implementation and verification evidence.
