When this bundle is later distributed or modified, selection.json can be replaced with a record naming a different winner or base protocol while formalslt verify still passes: the sidecar contains the certificate hash, but neither the certificate nor its verifier commits to the sidecar, recomputes selection_sha256, or checks the minimum-loss selection rule against the bound data. The Lean certificate therefore checks only the frozen point posterior's risk bound, not the advertised live-winner selection; include the selection record in the verified binding or add bundle verification that recomputes the selection.

Validate the prediction-stream binding before publication.
This records the digest from SOURCE_PREDICTIONS, but build_trace() does not compare it with evidence["data"]["prediction_stream_sha256"]. If CSV bytes change without changing the final metrics, this build succeeds and monitor.js later refuses to render the published monitor. Validate the two digests before writing the trace.

Bound protocol size and rational magnitude.
Uploaded names do not enter Lean identifiers, and csv.DictWriter serializes CSV headers safely. However, load_protocol accepts arbitrarily large canonical rational strings. Add request-size and rational numerator/denominator limits to prevent excessive CPU and memory use during certificate generation.

Skip this test when the pinned ML runtime is absent.
The skipif guard covers only the archive. Line 343 calls build_local_baseline_result, which imports NumPy and scikit-learn and raises ProtocolError when they are missing. A developer who has the local archive but installs only the standard-library path then gets a failure instead of a skip. applications/brier_monitor/README.md documents the default preparation path as standard-library only, so this combination is expected.
Add an import guard inside the test body.

Add a test for the duplicate-column rejection.
ServiceState.create rejects a protocol whose time, outcome, and model columns are not distinct. That check protects the CSV replay that the certificate binds. No test covers it.

Summary
Connect the exact live Brier monitor to the compact certificate engine, then expose the same flow through a local FastAPI service. The live preview remains uncertified until the frozen posterior and source rows pass independent replay and the generated Lean checker.
Depends on #147. Until #147 merges, GitHub's
main-based diff also displays those already-green application commits; after #147 merges, this PR reduces to the streaming and service slice. Targetingmainis required for this repository's pull-request CI workflow.Changes

Risk / Rollback
The service is intentionally unauthenticated, in-memory, and synchronous. Documentation binds it to localhost and explicitly excludes public deployment. FastAPI, Pydantic, Uvicorn, and HTTPX are added to the service/development dependency sets. Roll back this commit to remove the service and one-command selection handoff; the existing
monitorandcertifycommands remain separate and unchanged.Summary by CodeRabbit
