max_retry_depth
integer
default:3

Per-policy retry depth cap (TRU-362). Out-of-range values return HTTP 422.

Required range: 1 <= x <= 10
​
max_cascade_depth
integer
default:5

Per-policy cascade depth cap (TRU-371). Counts retry + fallback_model + prompt_modification combined per trace, across policies. Out-of-range values return HTTP 422.

Required range: 1 <= x <= 20

​
rule_yaml
string
required

Raw YAML DSL as authored. Opaque to the server in Phase 1.

​
trigger_type
enum<string>
required

Denormalised summary of the when: clause for fast filtering.

Available options:
eval_score,
anomaly,
failure_rate
​
action_type
enum<string>
required

Denormalised summary of the then: clause for fast filtering.

Available options:
retry,
fallback_model,
route_pct,
block,
escalate
​
rollout_pct
integer
required

Staged-rollout percentage. 0 means the policy is authored but inactive.

Required range: 0 <= x <= 100
​
dry_run
boolean
required

When true, the evaluator records observations without applying the action.

​
created_by
string
required

Clerk user ID of the author.

​
max_retry_depth
integer
required

Per-policy retry depth cap (TRU-362). When the executor counts this many or more previously-executed retry actions on a trace for this policy, the next retry is auto-converted to an escalate action and routed through the HITL pending_approval queue. Default 3.

Required range: 1 <= x <= 10
​
max_cascade_depth
integer
required

Per-policy cascade depth cap (TRU-371). Counts every remediation action on the trace — retry plus fallback_model plus prompt_modification — across all policies. When the count reaches this many, the next remediation is auto-converted to escalate and parked in the HITL queue. Distinct from max_retry_depth which counts retries only; both gates run per Execute call and whichever fires first wins. Default 5.

Required range: 1 <= x <= 20
