GetRegimeHistory returns the region's regime transition log newest-first. Entries are append-only from the seed writer, recorded only when diffRegionalSnapshot reports regime_changed. Premium-gated. PRO-gated. Requires an active Pro subscription.

## Query parameters

- `region_id` string, required
- `limit` integer
- `jmespath` string

## Response `200`

OK

- WorldmonitorIntelligenceV1GetRegimeHistoryResponse: GetRegimeHistoryResponse returns the region's regime transition log newest-first. The list is append-only from the seed writer's perspective: only diffs with regime_changed set produce an entry, so this is a pure transition stream (no steady-state noise).
  - `transitions` WorldmonitorIntelligenceV1RegimeTransition[]
    - `regionId` string
    - `label` string: Current regime label (the label the region just moved INTO).
    - `previousLabel` string: Previous regime label (the label the region was in before). Empty for the first-ever recorded transition for a region.
    - `transitionedAt` integer: Warning: Values > 2^53 may lose precision in JavaScript
    - `transitionDriver` string: Free-text driver string from the seed writer (e.g. "cross_source_surge"). May be empty.
    - `snapshotId` string: Snapshot id that materialized this transition. Points back to the full snapshot via intelligence:snapshot-by-id:v1:{snapshot_id}.

## Other responses

- `400`: Validation error
- `401`: Missing or invalid API key.
- `403`: Pro subscription required.
- `429`: Rate limit exceeded.
- `503`: Service unavailable. Billing-verification responses include code and X-Billing-Verification; other gateway infrastructure failures use the generic GatewayError shape.
