Section titled “Path Parameters”Request Body
Section titled “Request Body”Request body for POST /api/v1/orgs/{org}/projects. Named distinctly from the
dashboard’s own CreateProjectRequest — both
controllers share one Swagger document (see Program.cs’s AddSwaggerGen``DocInclusionPredicate override), and Swashbuckle’s default schemaId is the bare type
name, so an identical name in either namespace throws a schemaId collision at
--export-openapi time.

Section titled “Responses”Created
Public representation of a project, returned by GET /api/v1/orgs/{org}/projects (list),
GET .../projects/{project} (detail), and the body of a successful create/update. Drops
the dashboard-only nested Environments collection from ProjectDto — the
public API surfaces environments via their own endpoint (Task 6), not embedded here.
UpdatedAt is only populated from ProjectDto (the detail/create
shape); ProjectListItemDto doesn’t carry it, so list rows leave it null.
object
Capability hints: which operations the authenticated caller may perform on this resource, each with allowed + optional reason. Computed from the caller’s role and the resource’s state. Injected at runtime; safe to ignore. Present only on top-level resource responses — nested occurrences (e.g. a rule inside a targeting-config response) do not carry it.
object
One entry in a resource’s _actions block: may the caller perform it, and if not, why.

Section titled “Headers”The maximum number of requests permitted per rate-limit window for this caller.
The number of requests remaining in the current rate-limit window.
The UTC time at which the current rate-limit window resets, as a Unix timestamp in seconds.
Authentication is required, or the supplied API token is invalid or expired.
The frozen public-API error contract. error codes are stable snake_case strings. Wire keys
are frozen snake_case too (error, message, docs_url, fields,
retry_after) — the global camelCase naming policy would otherwise emit
docsUrl/retryAfter, breaking the published spec. !:JsonPropertyName
always wins over the policy, so these are pinned explicitly rather than relying on the
property names already being lowercase for the single-word ones.
did_you_mean and next_actions are ADDITIVE optional keys (null → omitted via
the global DefaultIgnoreCondition = WhenWritingNull), so pre-existing error bodies
are byte-for-byte unchanged when they’re absent.
