Run a regression check for a candidate manifest against the baseline
Run a regression check for a candidate manifest against the baseline.
Request body:
{
"agent_name": "support-agent",
"candidate_manifest_id": "mfst_xyz",
"pr_context": { # optional
"repo": "acme/support-bot",
"pr_number": 42,
"branch": "fix/refund-prompt",
"commit_sha": "abc123"
},
"trace_window_days": 30 # optional, default 30
}
Query params:
dry_run=true: compute the impact report but do NOT persist a
RegressionCheck row and do NOT consume the org's metered quota.
Useful for local exploration. The response has no `id` field
and the `pr_context` is ignored.
Response: an ImpactReport — see the response schema below.
Behavior on edge cases:
- No baseline exists → returns verdict='first_run', registers candidate
as baseline, status='completed' with zero impacts. The first check on
a new agent succeeds with nothing to compare against rather than
erroring, so CI can call this unconditionally from day one.
(Dry-run mode does not register the candidate as baseline either.)
- Candidate manifest doesn't exist → 404
- Candidate manifest belongs to a different agent → 400
