Edit Canvas
Sandboxed JS batch edit. Failures are atomic; committed-but-imperfect is success + requires_repair.
The response revision is advisory-until-read (the CRDT write-back
settles asynchronously); pin only tokens obtained from reads.

Headers
Calendar-dated API version pin. New integrations should pin 2026-05-01 to opt into the newest response shapes. For back-compat the server also accepts requests with no header and resolves them to the current default (today: 2026-04-12); that default advances on each sunset date. Any unsupported value returns 400 unsupported_version.
Available options:
2026-04-12, 2026-05-01 Example:
"2026-05-01"
