Update a Semantic Memory

post/v1/graphs/{graph_id}/operations/update-memory

Partially update a stored memory by its server-generated id. Only supplied fields change; the memory is re-embedded when text changes.

Idempotency: supply an Idempotency-Key header to make safe retries; replays within 24 hours return the same envelope. Reusing the key with a different body returns HTTP 409 Conflict.

Authentication

Authenticate in any one of these ways — not all of them:

API key in the X-API-Key header.
Bearer token in the Authorization header.
