--issue usable with the tracked bundle
In every fresh checkout, CERTIFICATE_DIRECTORY already exists because this commit tracks the generated certificate bundle, so the documented python3 scripts/build_brier_monitor_uci357_certificate.py --issue command always stops here before invoking the certificate engine. Either issue into a temporary directory and compare/replace the tracked bundle, or update the documented regeneration workflow so users do not have to discover and manually delete tracked output first.

The recorded revision is not an ancestor of reviewed commit 50b5444 (git merge-base --is-ancestor 6c61010 50b5444 fails), so a clean clone containing this squashed commit is not guaranteed to contain or resolve the revision named by the audited certificate. This breaks durable inspection of the exact source revision associated with the public checked result; record a revision reachable from the published history or use a stable tree/source binding instead.

The tracked trace contradicts this public claim: the boundary increases between 88 sampled points and, most visibly, rises from 0.022147 at observation 7,296 to the checked final value 0.073268 at observation 8,224. Users scrubbing the chart therefore see the opposite of the heading; describe the boundary as evolving rather than monotonically narrowing.

When stage_docs_site.py publishes the site, it replaces __FORMALSLT_SOURCE_REF__ inside index.html, so the deployed page no longer has the digest recorded here—the tracked template hashes to 91a9dd…, while even a representative staged rendering hashes differently. Consequently the published manifest's index.html entry cannot verify the file at that path and does not cover staging-time changes; compute or rewrite this digest after source-reference substitution.

These pins leave SciPy, the BLAS/LAPACK backend, and Python version unconstrained even though scikit-learn's lbfgs fit depends on that numerical stack. In an environment with the required NumPy and scikit-learn versions but a different solver/backend combination, the builder's version gate passes while coefficients or probabilities can differ; because --check byte-compares exact coefficient representations, evidence, and quantized predictions, the advertised pinned-runtime replay can then fail or reproduce a different artifact. Pin or record a complete reproducible numerical environment rather than only the two top-level packages.

Move runtime_requirements out of the models object.
Lines 57-60 place runtime_requirements inside models, next to constant_train_prevalence and logistic_all_sensor. The key comes from the metadata dictionary built at lines 215-218 of scripts/build_brier_monitor_uci357_certificate.py.
A consumer that enumerates models keys to list the candidate models sees three entries and treats the runtime record as a model. selection.model_order gives the authoritative enumeration, so nothing breaks today.
Promote the field to a top-level runtime key so models contains only models.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Clamp charted values to the fixed log domain.
yMax is 1, but the early boundary values exceed 1. The builder emits the first sampled point at n = 4, where boundary_upper_decimal is at least (0.7 + 3.05) / (0.5 * 4) ≈ 1.875 before the empirical term. For such a value, y(value) returns a negative coordinate, and .chart { overflow: visible } in monitor.css draws the boundary path above the plot area instead of clipping it.
Clamp the value into [yMin, yMax] before the log mapping.

Make fail resilient to missing nodes.
fail runs on the guard path at Line 318, which triggers when errorMessage or finalMarker is null. In that case Line 309 throws a TypeError inside fail, and no caller catches it. The status text then stays Checking instead of REFUSED, so an unverified page looks like a pending page. stage_docs_site.py validates only metadata markers, and the tests assert only data-certificate-status and data-scrubber, so a template edit that drops data-chart-error reaches this path.

pip require-hashes requirements file hash pinning reproducible install
💡 Result:
To achieve a reproducible, secure installation with pip using hash pinning, you must use Hash-checking Mode. This mechanism verifies that downloaded package archives match the expected cryptographic hashes specified in your requirements file, protecting against tampering and ensuring consistency [1][2]. Key components of this process include: 1. Requirement Pinning: You must pin every package and its transitive dependencies to a specific version using the == operator [1][2]. 2. Hash Specification: Each pinned requirement must include one or more --hash options in the requirements file [1][3]. For example: FooProject == 1.2 --hash=sha256:2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824 [2][4] 3. Enabling Hash-checking: - Automatic Activation: Pip automatically enables Hash-checking Mode if at least one requirement in your file includes a --hash option [3][5]. - Explicit Enforcement: You can force the use of this mode by passing the --require-hashes flag to the install command [1][5]. This is recommended for deployment scripts to ensure that hashes are present for all dependencies [1]. 4. Generating Hashes: You can use the pip hash command to compute the necessary hash digests for local package archives [6]. Important Considerations: - All-or-Nothing: When Hash-checking Mode is active, pip requires hashes for every package and every dependency listed [1][3]. - Multiple Archives: A package may have multiple archives (e.g., source and binary wheels). You must provide hashes for all of them, or pip may encounter a hash mismatch if it fetches an alternative archive [6][3]. - Compatibility: Because Hash-checking Mode requires all dependencies to be explicitly listed and hashed, it is incompatible with non-pinned requirements or packages installed from local directories or VCS URLs [1][3]. For managing complex dependencies, tools like pip-tools are frequently used to automate the generation of pinned, hashed requirements files [4].

The certificate builder re-implements three utilities that source_protocol already provides. The module imports source_protocol at line 30, yet redefines canonical JSON serialization, rational formatting, and atomic writing. All three sit on the path that produces the tracked artifacts and their SHA-256 bindings, so divergence between the copies changes tracked digests silently. One copy is also strictly weaker than its sibling.

Print the failure message to stderr.
scripts/formalslt_certificate.py prints its ERROR: line with file=sys.stderr. This script prints to stdout, so a CI job that separates streams reports the failure text as normal output.
♻️ Proposed fix
- print(f"ERROR: UCI monitor site refused: {error}")
+ print(f"ERROR: UCI monitor site refused: {error}", file=sys.stderr)Add import sys to the imports.

Validate the observed_at_utc type and format.
Line 300 requires the observed_at_utc key, but no later check validates it. A non-string value or a malformed timestamp passes validate_protocol. Every other pinned dataset field uses _exact, _string, or _sha256.
Add a _string check and a datetime.strptime round-trip so the recorded observation time is well-formed.

Remove the unreachable allowlist leakage loop, or gate the exact-equality check.
Line 415 asserts _exact(allowlists, EXPECTED_ALLOWLISTS) unconditionally. That check is not gated by enforce_frozen_identity. Any allowlist deviation therefore fails at line 415, so the per-allowlist checks at lines 427-433 can never raise.
This makes the leakage guard untestable. test_feature_allowlist_rejects_leakage matches "feature allowlists", which is the message from line 415, not the leakage messages from lines 431 or 433. The test does not exercise the guard it names.
Gate line 415 behind enforce_frozen_identity so the structural leakage checks become reachable for non-frozen protocols.
♻️ Proposed change to make the leakage guard reachable
allowlists = _object(feature_contract["allowlists"], "feature allowlists")
- _exact(allowlists, EXPECTED_ALLOWLISTS, "feature allowlists")
+ if enforce_frozen_identity:
+ _exact(allowlists, EXPECTED_ALLOWLISTS, "feature allowlists")

Make the binding digest assertion independent of the manifest.
Lines 255 and 260 read the expected sha256 from bindings[0] and bindings[1]. The assertion compares each digest to itself, so it verifies only path and role.
The recomputation at lines 263-266 does check the digests, so coverage is not lost. Assert the path and role list separately to make the intent clear.

Summary
Add a reproducible UCI Occupancy Detection application for the finite tabular Brier certificate profile. The tracked 8,224-observation replay selects an all-sensor logistic model after the monitored prefix, records Brier loss 0.0611976886..., and checks a 95% upper bound of 0.073268.

This is an audited retrospective demonstration. It certifies encountered conditional prefix Brier risk; it does not establish future occupancy, population risk, real-time label delay, or deployment performance. The raw UCI archive remains untracked; the derived quantized prediction stream and all bindings are tracked. Roll back by reverting this PR.
