Shapes

WarmHub does not currently mount REST endpoints under /api/repos/:orgName/:repoName/shapes.

Use these supported surfaces instead:

Task	Surface
Read repository data filtered by shape	GET /api/repos/:orgName/:repoName/head?shape=... or GET /api/repos/:orgName/:repoName/query?shape=...
Create, revise, or retract shapes	SDK commit APIs, wh commit submit, or warmhub_commit_submit
Manage shapes with higher-level helpers	SDK shape APIs or wh shape

Shape writes are repository data writes. They flow through the same operation pipeline as thing and assertion writes, so they share the same validation, history, and per-operation result contract across CLI, SDK, and MCP. See Atomicity for the full contract.
