Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🔵 Low · up to The PR adds a static certificate and browser monitor, but certificate verification does not currently confirm the pinned protocol file itself and CI may accept a recorded proof result without rerunning Lean; stylesheet validation may also fail on the new CSS. The change is mergeable with explicit owner awareness and follow-up on these bounded integrity and readiness risks. Sequence Diagram(s)sequenceDiagram

The validator checks only the exact rational fields, while both _print_summary and monitor.js display the separate *_decimal fields. In the docs-scope CI path, changing values such as posterior_empirical_brier_risk_decimal, kernel_checked_upper_bound_decimal, or confidence.level_decimal still makes verify --skip-lean print PASS while the CLI and public monitor show arbitrary results. Validate these representations against decimal_text(...) or derive them at display time so the published claims remain tied to the checked values.

This only checks that the trace and certificate repeat the same receipt digest; default verification never compares data.stream_sha256 or data.receipt_sha256 with the constants in GJPBrierMonitorReplayData.lean. Consequently, changing both data hashes, updating the trace's self-pin, and recomputing its hash still passes the normal verify --skip-lean command even though the certificate no longer names the replay checked by Lean. Compare the certificate hashes directly with the tracked Lean pins even when --artifacts is omitted.

Iterating over sources permits an empty list, and the validator also never checks the embedded Lean status, theorem name, allowed axioms, or observed axioms. A certificate with sources: [], an unrelated theorem, and an unexpected axiom still passes verify --skip-lean, which is exactly the command used by docs-only CI, allowing proof provenance to be removed or falsified while the certificate reports PASS. Require the expected source records and validate the full checker result against the focused theorem and permitted axiom set.

Fix the configured Stylelint errors.
Stylelint reports value-keyword-case errors for Inter, BlinkMacSystemFont, Consolas, optimizeLegibility, and currentColor. These errors can fail the stylesheet validation gate. Make these values conform to the configured rule, or update the rule if these canonical spellings are intentional.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Remove the unused kernel hypothesis _hP.
The proof at Line 476 uses only hempirical, hquadratic, and hpath. _hP : ∀ n u, IsPMF (P n u) is never used, so the statement holds for an arbitrary P that is not a PMF family. Keeping it implies a kernel-validity requirement that this theorem does not need, which weakens statement faithfulness. replayCountableStrategyRiskEvent_failureMass_le still needs hP, so the coverage side is unaffected.

Hash the protocol file and validate the certificate pin.
validate_tracked_replay_pins compares only the Lean constant with the receipt’s self-reported protocol_sha256. Hash PROTOCOL with sha256_file and compare that digest with both values. Also validate certificate["data"]["protocol_sha256"] in validate_certificate so verify without --artifacts checks the protocol.

Summary
Add a compact executable certificate and browser-based real-data monitor for the pinned Good Judgment Project Brier replay. The receipt separates raw-data replay from Lean theorem checking and preserves the preregistered study's failing verdict.
Changes
The certificate reports 175 observations, observed posterior Brier loss 0.04795917, replayed anytime boundary 0.13802560, compact Lean endpoint
< 0.131, and confidence 0.99375. Certificate verification passes; the separate preregistered study verdict remainsFAIL.Verification

Risk / Rollback
The theorem slice uses a retrospectively fixed countable strategy catalog. It is not a prospective result for this dataset and does not establish future, stationary, or deployment risk. Python independently replays raw bytes into exact summaries; Lean checks theorem specialization and endpoint arithmetic from those summaries. Revert the three feature commits and merge commit to remove the slice.
