versioning:
  scheme: protobuf-package
  current: v1
  docs: https://docs.touchmark.ai/sdk/overview
  notes: The wire contract is proto/touchmark/v1/session.proto (touchmark.v1).
    The docs commit to additive evolution in at least one place - v1 realizes the
    valuation stream as a repeated long-poll, and server-push is described as "a
    later, additive upgrade behind this exact same method - your code won't
    change". Payload schemas live server-side per application, so new event
    shapes are added "without an SDK upgrade". Multi-currency is undefined in v1
    (USD only).
deprecation:
  policy_url: null
  sunset_header: false
  notes: No deprecation policy or RFC 8594 Sunset/Deprecation header support is
    published.
sla:
  url: null
  notes: No SLA is published. The docs explicitly state scoring latency is
    unbounded - a network timeout "is not an eval-completion SLA (scoring is
    asynchronous and unbounded)".
status_page: null
session_lifecycle:
  - Sessions are opened per scope with session.start (idempotent on scope_id).
  - Sessions lapse server-side after about one week with no emits; consuming the
    valuation stream does not reset the clock. The next emit or end on a lapsed
    session throws session_closed.
  - session.end closes a session early, shedding its long-poll load and freeing
    the scope_id for a fresh session; late re-valuations still arrive on the
    stream after end.
  - The public no-account session page shows the last 24 hours of session
    activity; older events stay in Touchmark's retained log.
