Only company_id and optional school_id are accepted; all other parameters return 400. With school_id, the school must be assigned to the session and its name selects the snapshot entry. Without school_id, the current implementation matches session school entries directly against the snapshot keys, which are school names; UUID-based assignments can therefore yield an empty map. Returns a nested map without pagination or collection headers. ## OpenAPI ````yaml /openapi.yaml get /spaces openapi: 3.1.0 info: title: Primula Tracker API V3 version: 3.0.0 description: >- Reference for the 66 operations registered under `/primula/api/v3` in the V3 release baseline. ## Authentication Create a session with `POST /sessions`, then send `Authorization: Bearer ` on protected operations. Tokens must remain associated with a valid server-side session. The returned refresh token has no refresh endpoint in V3. Session company and school restrictions are documented per operation; company_id is not inferred from the token. ## Responses and errors Collections generally return bare JSON arrays and items return bare JSON objects. Report objects, nested maps, and update summaries are explicitly described below. List metadata travels in response headers rather than an envelope. Empty lists written by collection helpers are `[]`; fields backed by nullable values may be `null`, and omitted properties are distinguished from null properties in schemas. Handlers generally return `{ "error": "message" }`; authentication middleware and activity proxy errors use plain text. Unsupported methods on a registered path return 405 with Allow after any applicable authentication checks. ## Pagination and projections Only operations documenting page/per_page support pagination. Defaults are page=1 and per_page=100. Values exceeding the documented effective cap are clamped, not rejected. X-Total-Count describes the full matching set. Link contains applicable navigation links and is omitted for a single page. Aggregates use limit (default 50, effective cap 200) instead of pagination and send X-Truncated only when rows were omitted. The fields parameter, where available, selects the exact response properties; unsupported fields return 400. ## Query encoding Multi-value parameters documented as arrays accept repeated keys or comma-separated values. Prefer repeated keys for long UUID lists. Except for the two activity proxy operations, query parsing drops the entire query string above 8192 bytes and truncates each decoded query value to 128 bytes. Parameter combinations and interpretation differ by resource and representation; consult each operation. Unknown parameters are rejected only where explicitly documented. ## Dates and writes Calendar dates use YYYY-MM-DD, monthly periods use YYYY-MM, and timestamp formats are described in the corresponding schema. Defaults such as today depend on the server clock. PATCH operations change only the documented properties and reject unknown body properties. Clearing values, authorization, and partial-write behavior vary by resource and are described per operation. Examples use synthetic identifiers and placeholder tokens.
