Changelog

All notable changes to STEM BIO-AI are documented in this file.

Format follows Keep a Changelog. Versioning follows Semantic Versioning.

IMMUTABLE formula changes require a minor version increment (1.x.0). Rubric refinements and additions use patch versions (1.0.x).

[Unreleased]

[1.8.0] - 2026-05-31

Added

  • Added explicit MICA invocation runtime surfaces for session-start governance:
    • tools/mica_runtime.py --format session-report
    • tools/mica_invoke.py --mode {natural|guided|forced}
    • mica_invoke.bat Windows wrapper
  • Added SECURITY.md so the default deterministic scan boundary, advisory/provider boundary, and verification path are documented as first-class repository surfaces.
  • Added focused regression coverage for the new MICA invocation/session-report path in tests/test_mica_invocation.py.

Changed

  • Refreshed the tracked HTML preview artifact under docs/assets/report-preview/yorkeccak_bio_report.html from a real 1.8.0 generated report so the README/browser preview matches the current runtime surface.

[1.7.9] - 2026-05-31

Changed

  • Improved audit artifact inspectability by promoting bounded AIRI trigger semantics over bare coverage counts: report surfaces now emphasize AIRI Risk Triggers, expose primary/secondary detector roles, and show mapping reasoning directly in human-readable artifacts.
  • Reduced repeated evidence noise across the artifact stack by compacting repeated same-file evidence in HTML and explain surfaces, documenting the same readability rule in Markdown, and surfacing explicit canonical-boundary notes for JSON and PDF outputs.
  • Humanized top-risk summaries and remediation targets so detector output appears as reviewer-usable audit findings instead of raw check IDs, while still preserving full-fidelity detector detail in JSON.
  • Added bounded tier-impact and partial-credit semantics to rubric surfaces so Stage 1/2R/3 findings are easier to trace without changing score math.
  • Reduced detector_bio.py repeated AST parse/parent-annotation overhead by building file AST contexts once per scan, pre-bucketing core node classes (Constant, Assign, Call, Try, If), and reusing them across the SMILES, parser-guard, silent-mock, and run-trace collectors. This is a semantics-preserving performance optimization only.
  • Tightened bio-detector scan boundaries by excluding .manual_verify from generated/non-runtime paths and replacing the broad trace-manifest rglob("*") walk with a pruned filesystem traversal that preserves existing detector semantics while lowering trace-scan overhead.
  • Deferred the RDKit optional lane until at least one SMILES-like candidate is present, and cached the optional rdkit.Chem import so availability/import work is not repeated unnecessarily across candidate checks.
  • Added a file-signature AST context cache for detector_bio.py so repeated scans of unchanged Python files in the same process avoid redundant ast.parse/compile work while keeping detector semantics unchanged.
  • Changed the CLI default report depth from --level 1 to --level 3, so the plain stem <repo> path now emits the full packet by default unless the user selects a shallower level.
  • Reworked ReportLab PDF pagination so the brief, standard, and full packet tiers now honor their intended page counts, keeping the executive/regulatory summary on page 1 instead of allowing silent overflow into extra pages.
  • Redefined detailed packet tiers so --level 2 now emits a standard 5-page review packet and --level 3 emits the full 7-page packet, restoring Stage 4 as a dedicated PDF page and preventing end-of-report overcrowding in the former 5-page Level 3 path.

[1.7.8] - 2026-05-17

Added

  • Added additive C6_mock_auth_or_fail_open_boundary detection so mock authentication, auto-login, or no-auth self-host/local trust-boundary signals can surface as a dedicated Code Integrity lane without changing formal score math.

Changed

  • Updated Markdown, explain, HTML, and PDF output surfaces so C6 appears consistently across code_integrity, report cards, remediation guidance, and proof traces.
  • Clarified public documentation and API descriptions from C1–C5 to C1–C6, and documented that C6 is currently a report-layer/code-integrity warning rather than an AIRI-mapped detector lane.
  • Performed a safe detector_bio.py structural cleanup by extracting the shared AST-path iteration helper and reusing it across multiple bio detectors, reducing duplicated parsing logic without changing detector semantics.
  • Rotated the active package, CLI, documentation, policy, and MICA version surfaces to v1.7.8.

[1.7.7] - 2026-05-16

Changed

  • Split the former overloaded C4 output surface so executable fail-open exception handling remains in C4_exception_handling_clinical_adjacent_paths, while unsupported compliance or clinical-boundary integrity warnings now surface in the new C5_compliance_boundary_integrity lane.
  • Added additive detector traceability to stage_2r_rubric and stage_3_rubric items through detector_id and decision_basis, making summary and report outputs more inspectable without changing score math.
  • Extended AIRI covered-risk records with additive mapping_details reasoning objects so report surfaces can explain why a detector mapped to a specific AIRI risk instead of showing only the coverage count.
  • Updated Markdown, explain, HTML, and PDF report surfaces so AIRI examples now show bounded why mapped reasoning and Code Integrity surfaces expose the new C5 lane.
  • Rotated the active package, CLI, documentation, policy, and MICA version surfaces to v1.7.7.

[1.7.6] - 2026-05-16

Changed

  • Expanded Stage 3 provenance and Stage 4 replication evidence recognition for JavaScript repositories so package.json, package-lock.json, pnpm-lock.yaml, yarn.lock, and npm-shrinkwrap.json now count as dependency/provenance or lock-resolution surfaces where appropriate.
  • Corrected a false-negative path where JavaScript lockfiles were previously ignored in B1_data_provenance_controls, S4_environment_lock_evidence, and S4_exact_dependency_pins_or_hashes, materially changing affected repo scores without changing the formal tier definitions.
  • Added additive R2R_D5_single_external_service_dependency detection so repositories can now surface vendor/API lock-in risk in the report layer when self-host or local-operation claims coexist with required named external service dependencies.
  • Connected the new external-service dependency signal into code_integrity as a C2 warning path and into AIRI coverage when detector mappings are present, while still keeping it out of formal score math.
  • Added additive S1_R2_unsupported_legal_or_compliance_claim detection so unsupported HIPAA, FDA-ready, CE-ready, clinical-grade, and similar claim language can surface in the report layer when reviewed sources lack stronger governance-grounding evidence.
  • Connected unsupported legal/compliance claims into Stage 1 regulatory traceability as COMPLIANCE_CLAIM_GROUNDING_SIGNAL, into code_integrity as a C4 warning path, and into AIRI coverage where bounded mappings exist, while keeping the signal out of formal score math.
  • Rotated the active package, CLI, documentation, policy, and MICA version surfaces to v1.7.6.

[1.7.5] - 2026-05-13

Added

  • Added additive evidence-ledger quality fields so findings now surface evidence_status and confidence directly in runtime artifacts and report surfaces.
  • Added audit_freshness metadata to scan results, including review-cycle guidance, expiry date, and change-triggered re-audit hints.

Changed

  • Surfaced audit-freshness summaries in Markdown, explain, and HTML outputs so review packets show recency expectations explicitly instead of leaving them implicit.
  • Narrowed Stage 1 regulatory-responsibility scoring so self-asserted HIPAA or privacy/compliance language no longer receives full regulatory-framework credit; these claims now surface as weaker governance signals that require independent verification.
  • Narrowed Stage 4 dataset-link scoring so generic external data API marketing links no longer count as dataset/data-source reproducibility evidence.
  • Added a first-class S1_R2_weak_regulatory_self_assertion evidence signal so weak compliance claims are visible in the evidence ledger and explain output instead of appearing only in rubric math.
  • Kept self-asserted compliance risk in the report/scoring layer only; this signal is not yet mapped into AIRI detector coverage and should not be interpreted as AIRI-supported risk coverage.
  • Cleaned two confirmed single-file slop findings in active runtime surfaces:
    • removed an unused json import from stem_ai/scanner.py
    • replaced an empty except branch in stem_ai/render_html.py with explicit continue
  • Rotated the active package, CLI, documentation, policy, and MICA version surfaces to v1.7.5.

[1.7.4] - 2026-05-13

Added

  • Added simulation-only local profile-file support to stem policy simulate, allowing schema-valid researcher profile experiments without registering a new named policy or opening the authoritative score path.

Changed

  • Surfaced AIRI summary material more clearly across the demo and report outputs, including the Hugging Face overview card and markdown/explain report sections.
  • Clarified policy simulation output so replication-lane posture changes, cap effects, and mirror-only boundaries are explained directly instead of appearing as unexplained zero-delta previews.
  • Standardized default CLI artifact routing under stem_output/<repo_slug> whenever the output root is stem_output.
  • Refined the Hugging Face demo layout so the overview cards stay in a stable 3-column desktop grid instead of expanding to 4 columns on wide screens.
  • Simplified advisory packet section traversal in stem_ai/advisory_contract.py with a low-risk helper extraction.
  • Rotated the active package, CLI, documentation, policy, and MICA version surfaces to v1.7.4.

Notes

  • PyPI uploads for this release should use freshly built 1.7.4 artifacts only. Do not upload stale archives from older dist/ contents.

[1.7.3] - 2026-05-13

Changed

  • Removed two confirmed unused helpers from the active runtime surface:
    • stem_ai/detectors.py::collect_evidence
    • stem_ai/app.py::_gradio_major
  • Refreshed the Hugging Face / Gradio demo text in stem_ai/app.py so the UI no longer advertises stale 1.6.0 wording and now reflects the current deterministic layer set.
  • Tightened the Hugging Face overview-card grid in stem_ai/app.py so desktop layouts stay at a stable 3-column arrangement instead of expanding to 4 columns on wide screens, while still collapsing responsively on smaller widths.
  • Standardized CLI artifact output under stem_output/<repo_slug> whenever the output root is stem_output, so repeated local scans stay grouped by target repository without changing other custom output paths.
  • Rotated the active package, CLI, policy, documentation, and MICA version surfaces to v1.7.3.

Verified

  • Confirmed the removed helpers had no active runtime callers in the current repository.
  • Re-ran import smoke for stem_ai.detectors after dead-code removal.
  • Added regression coverage for stem_output/<repo_slug> output routing in the CLI scan path.

[1.7.2] - 2026-05-12

Changed

  • Tightened .slopconfig.yaml so temporary and generated analysis paths (tmp, build, audits, stem_output*, .manual_verify) are excluded more explicitly from local structural inspection runs.
  • Removed unused HTML renderer imports in stem_ai/render_html.py, reducing inspection noise without changing report behavior.
  • Simplified stem_ai/detector_contract.py by extracting shared Python-module traversal and public-function iteration helpers, reducing repetition while preserving detector outputs.
  • Revalidated the shipped calibration profiles against 1.7.2 and rotated public package, CLI, documentation, policy, and active MICA version surfaces to v1.7.2.

Verified

  • Confirmed P0/P1 parity on a same-target self-scan comparison (A vs B) with no drift in:
    • score.final_score
    • score.formal_tier
    • code_contract
    • detector_summary
    • airi_risk_coverage
    • evidence_ledger count

[1.7.1] - 2026-05-12

Added

  • Added a governed local AIRI data layer with three packaged registries:
    • stem_ai/data/airi_registry_full.v1.json — normalized full local registry derived from the upstream AIRI CSV snapshot
    • stem_ai/data/airi_runtime_bundle.v1.json — curated deterministic runtime bundle
    • stem_ai/data/airi_detector_mapping.v1.json — detector-to-risk mapping registry with bundle/full-scope gap labels
  • Added AIRI governance and attribution documents:
    • docs/AIRI_DATA_GOVERNANCE.md
    • docs/THIRD_PARTY_DATA.md
    • docs/airi_registry.schema.json
    • docs/airi_detector_mapping.schema.json
  • Added regression coverage for AIRI registry/bundle/mapping provenance surfacing and bundle-scope gap separation.

Changed

  • Replaced hardcoded AIRI detector mappings and known-gap lists in stem_ai/airi_risk_mapping.py with packaged local registry files so provenance, runtime scope, and mapping governance are separated explicitly.
  • Updated AIRI coverage outputs to surface registry version, runtime bundle version, mapping version, upstream snapshot date, license, attribution note, and split known gaps into known_gaps_in_bundle and known_gaps_outside_bundle.
  • Corrected HTML score-matrix T0 hard-floor wording to match the authoritative 39-point cap used by the scanner and scoring rationale.
  • Strengthened AIRI wording across README, HTML report docs, API contract, calibration architecture, and runtime output so the scanner’s curated runtime bundle is not confused with the full upstream AIRI universe.
  • Rotated package/version surfaces to v1.7.1 and packaged the new AIRI registry artifacts.

[1.7.0] - 2026-05-12

Added

  • Layer 2 AST Contract Detectors (CC-1 / CC-2 / CC-3) — new stem_ai/detector_contract.py module performing Python AST analysis beyond surface-scan reach:
    • CC1_clinical_zero_default: detects keyword-only and positional function parameters named confidence_threshold, score_threshold, min_confidence, etc. defaulted to 0.0 — a silent fail-open pattern in clinical inference paths.
    • CC2_api_contract: cross-checks names documented in README against __all__ exports; flags phantom APIs (documented but not exported).
    • CC3_shallow_validator: identifies validate_* / check_* functions that use only len() (length gate) without regex structure validation — insufficient for PII/clinical data fields.
  • MIT AI Risk Repository (AIRI) V4 integration — new stem_ai/airi_risk_mapping.py and stem_ai/data/airi_medical_risks.json (184 curated medical/clinical risk entries). Every scan now produces an airi_risk_coverage section mapping triggered detectors to their AIRI risk IDs, coverage rate, and known gaps.
  • Interactive 5-section HTML dashboard — --format html (and --format all) now generates a self-contained interactive report with:
    • Sticky nav with scroll-spy active state
    • SVG semicircle score gauge + tier badge in hero header
    • Expandable code-integrity cards (click to reveal full evidence list)
    • AIRI covered/gaps toggle buttons
    • Evidence ledger filter chips (FAIL / WARN / PASS / INFO)
    • Tooltip ? icons on every metric header (CSS ::after, no JS)
    • Hover transitions and keyboard accessibility throughout
  • stem_ai/render_html_components.py and stem_ai/render_html_styles.py — renderer split into three focused modules (each < 250 lines).
  • docs/UI_HTML_REPORT.md — full specification for the HTML dashboard format, interactive features, and AIRI coverage mapping.
  • docs/assets/html_report_preview.png — screenshot of the interactive HTML report.

Changed

  • stem_ai/scanner.py — wired CC-1/CC-2/CC-3 findings into code_contract result key; CC WARN entries surface in notable_risks; build_airi_coverage() called at the end of every scan.
  • Rotated the active MICA memory layer and public package/version surfaces to v1.7.0.

[1.6.8] - 2026-05-11

Added

  • Added root CITATION.cff and .zenodo.json so GitHub releases can be archived as DOI-backed software records through Zenodo.
  • Added regression coverage for profile-aware C1 penalty simulation and preview-only post-delta profile validation.

Changed

  • Hardened stem policy simulate so preview scoring now uses the selected profile's C1_penalty when the baseline scan has already triggered C1, instead of assuming the runtime constant forever.
  • Revalidated effective preview_only profiles after bounded deltas are applied, keeping future preview expansion inside the same runtime policy guardrails as packaged profiles.
  • Strengthened mirror-only wording across CLI, Markdown, explain, calibration-architecture, and API-contract surfaces so scan --policy <name> is not confused with score-authoritative policy simulation.
  • Rotated the active MICA memory layer and public package/version surfaces to v1.6.8.

[1.6.7] - 2026-05-11

Added

  • Added stem policy derive as an auditable researcher-intent translation surface built from the documented 0-5 rule table.
  • Added stem policy simulate <repo> so users can preview named-profile or preview-only policy outcomes against a real repository before any authoritative score changes are enabled.
  • Added deterministic translation and simulation helpers for top-down rule matching, preview-only bounded deltas, and policy-tier/cap preview math.
  • Added regression coverage for intent translation, preview-only fallback, and CLI derive/simulate outputs.

Changed

  • Kept formal scan scoring unchanged while adding governed derive/simulate UX, so 1.6.7 narrows the user-policy gap without turning the CLI into a free-form tuning console.
  • Clarified calibration documentation so the profile contract, policy visibility, and derive/simulate preview lanes are described as implemented mirror-only architecture rather than as a future-only proposal.
  • Rotated the active MICA memory layer and public package/version surfaces to v1.6.7.

[1.6.6] - 2026-05-10

Added

  • Added stem policy list and stem policy explain <name> so named calibration profiles can be inspected directly from the CLI.
  • Added --policy <name> to scan, gate, and advisory workflows so selected profiles are surfaced consistently in result metadata and stdout summaries.
  • Added regression coverage for policy list/explain CLI behavior and selected-profile metadata surfacing.

Changed

  • Extended Markdown, explain, and PDF header surfaces to show the active calibration profile name, status, and read mode.
  • Kept policy selection mirror-only in 1.6.6 so named profiles remain visible and testable before any score-authoritative read-through is enabled.
  • Rotated the active MICA memory layer and public package/version surfaces to v1.6.6.

[1.6.5] - 2026-05-10

Added

  • Added stem_ai.calibration_profile for Phase 1 mirror-only calibration profile loading, validation, and canonical policy hashing.
  • Added packaged policy artifacts: policy/scoring_profile.schema.json, policy/scoring_profile.default.v1.json, and policy/scoring_profile.strict_clinical_adjacency.v1.json.
  • Added calibration profile metadata to result objects so outputs now surface policy_version, profile_name, profile_status, profile_read_mode, and canonical policy_sha256.
  • Added regression coverage for calibration profile validation, metadata surfacing, and Markdown / explain rendering.
  • Added a fixture-format example for Phase 1 profile parity under tests/fixtures/calibration_profiles/.

Changed

  • Kept scoring behavior unchanged while introducing mirror-only profile validation so Phase 1 remains parity-first rather than behavior-changing.
  • Updated docs/API_CONTRACT.md and docs/CALIBRATION_PROFILE_DESIGN.md to define Phase 1 calibration metadata, fixture format, and schema/runtime validation boundaries.
  • Rotated the active MICA memory layer and public package/version surfaces to v1.6.5.

[1.6.4] - 2026-05-10

Added

  • Added CA taxonomy provenance fields to the public classification surface so outputs now record the active runtime taxonomy version and source.
  • Added regression coverage for CA taxonomy metadata surfacing and tightened B2 threshold behavior.

Changed

  • Tightened Stage 3 B2 entry criteria so a minimal single-term limitations mention no longer receives partial credit without structured boundary language.
  • Clarified in public docs that the active clinical-adjacent taxonomy remains a runtime scanner.py authority and that reference markdown is informative, not authoritative.
  • Rotated the active MICA memory layer and public package/version surfaces to v1.6.4.

[1.6.3] - 2026-05-10

Added

  • Added AST analysis scope surfacing to stdout, Markdown reports, and PDF outputs when deterministic AST scanning is capped by file-count limits.
  • Added docs/CALIBRATION_PROFILE_DESIGN.md as a design proposal for future versioned scoring-policy profiles.
  • Added regression coverage for AST cap surfacing across CLI, Markdown, and PDF fallback outputs.
  • Added regression coverage for negative-context provenance handling in Stage 3 B1 scoring.

Changed

  • Tightened Stage 3 B1 provenance scoring so negative or non-approval IRB / data-source contexts no longer receive maximum provenance credit.
  • Updated docs/SCORING_RATIONALE.md with executive summary, quick reference, key terms, deliberate scope boundaries, and explicit order-of-operations onboarding.
  • Rotated the active MICA memory layer and public package/version surfaces to v1.6.3.

[1.6.2] - 2026-05-08

Added

  • Added workflow-oriented CLI entry points: stem scan, stem gate, and stem advisory validate|packet|call|check-response.
  • Added --summary full|compact|off stdout control with command-specific defaults (scan=full, gate/advisory=compact).
  • Added --output as a clearer alias for --out.
  • Added regression coverage for the new workflow-oriented CLI paths and shorthand compatibility.
  • Added pytest.ini to ignore transient local output/temp directories during test collection.

Changed

  • Reframed the CLI around user intent instead of one long option string while preserving stem <folder> and stem audit ... compatibility.
  • Updated README and docs/CLI_REFERENCE.md to document the new workflow model and migration path from legacy inline advisory/gate flags.
  • Promoted package metadata and public version references to v1.6.2.

[1.6.1] - 2026-05-08

Added

  • Added --tier-gate T0|T1|T2|T3|T4 CLI flag for CI/CD pipeline integration: exit code 1 if the audit tier is below the required threshold.
  • Added --quiet CLI flag to suppress human-readable stdout summary while still writing artifacts.
  • Added enriched CLI stdout summary with per-stage scoring breakdown (Stage 1–4), clinical adjacency status, code integrity warnings, bio diagnostics, and regulatory review flags.
  • Added AI usage transparency line to stdout: always reports whether the scan used deterministic-only mode or advisory provider mode.
  • Added remediation hints from notable_risks (top 3 action items displayed in stdout).
  • Added if __name__ == "__main__" guard to cli.py so python -m stem_ai.cli works as a valid entry point.
  • Added docs/CLI_REFERENCE.md documenting all CLI flags, stdout format, CI/CD integration examples, exit codes, and AI transparency features.

Changed

  • CLI stdout now surfaces data from v1.3.0–v1.6.0 engine features (replication lane, bio diagnostics, regulatory traceability) that were previously only available in JSON/Markdown/PDF artifacts.
  • Updated README Quick Start section with CI/CD gate examples and CLI reference link.
  • Updated version badge and citation to v1.6.1.

[1.6.0] - 2026-05-06

Added

  • Added a registry-driven regulatory traceability output layer with regulatory_basis, stage_traceability, and regulatory_traceability fields in the local CLI result object.
  • Added report/explain/PDF regulatory basis note rendering using docs/regulatory_basis_registry.v1.json and its JSON schema.
  • Added automated review_required checks for stale registry month labels, draft-guidance presence, and missing required regulatory source families.
  • Added direct surfacing of bio-detector scope notes so not_detected and not_applicable statuses explain what was and was not assessed.

Changed

  • Promoted the local CLI result schema to stem-ai-local-cli-result-v1.6 to match the now-stable traceability payload shape.
  • Hardened regulatory traceability semantics so negative or missing Stage 1 boundary signals no longer read as positive Article 13 alignment.
  • Lowered reasoning diagnostics wording from model-like confidence language to explicit heuristic language (heuristic_consistent, low_spread, within_heuristic_gate) and surfaced uncalibrated priors directly in report text.
  • Updated package metadata, README, MICA active memory layer, and public docs for the v1.6.0 release.

Fixed

  • Restricted offline advisory fallback citations to active evidence states (detected, error, manual_review_required) so absent or not-detected findings no longer masquerade as priority evidence.
  • Regenerated ClawBio dogfooding artifacts against the live v1.6.0 code path to confirm new schema, traceability wording, and detector-scope notes are rendered consistently.
  • Removed superseded deterministic-diagnostics proposal indirection from the active public docs surface so the 1.6.0 implementation pair is now DETERMINISTIC_DIAGNOSTICS.md plus REGULATORY_MAPPING.md.

[1.5.11] - 2026-05-06

Added

  • Added BIO_smiles_rdkit_validation as an optional A1 lane that emits stronger evidence when RDKit is available and rejects invalid hardcoded SMILES-like candidates.
  • Added regression coverage for RDKit-lane unavailable / invalid / valid paths and for AllChem.MolFromSmiles parser-guard detection.

Changed

  • Tightened BIO_smiles_surface_integrity precision by excluding generated surfaces (build/, dist/, audits/), hex colors, version/hash/schema strings, and other non-chemistry token patterns.
  • Expanded SMILES parser-guard detection to include AllChem.MolFromSmiles.
  • Updated the deterministic diagnostics spec to mark A1 as implemented and to document the current evidence-only behavior.
  • Rotated the active MICA memory layer to v1.5.11 for the SMILES precision and RDKit-lane patch release.

Fixed

  • Eliminated major SMILES false positives observed during dogfooding on AI-SLOP-DETECTOR, STEM-BIO-AI, and BioClaw.
  • Corrected RDKit-lane status semantics so environments with RDKit installed but no invalid candidates report not_detected instead of not_applicable.

[1.5.10] - 2026-05-06

Added

  • Added stem_ai/detector_bio.py with deterministic evidence-only bio diagnostics for conservative SMILES surface checks, SMILES parser-guard checks, silent mock fallback detection, traceability manifest surface detection, and bio-tool subprocess run-trace heuristics.
  • Added Markdown and --explain surfacing for bio deterministic diagnostics in audit outputs.
  • Added regression coverage for bio diagnostics and explain/Markdown surfacing.
  • Added docs/DETERMINISTIC_DIAGNOSTICS.md as the promoted active deterministic diagnostics specification.
  • Added docs/REGULATORY_MAPPING.md to the public docs surface and package manifest.

Changed

  • Promoted docs/DETERMINISTIC_DIAGNOSTICS_PROPOSAL.md to a pointer document and moved active documentation to docs/DETERMINISTIC_DIAGNOSTICS.md.
  • Linked README proof surfaces to deterministic diagnostics and regulatory traceability docs.
  • Rotated the active MICA memory layer to v1.5.10 for the bio-detector implementation release.

Fixed

  • Restored bio-detector integration to the evidence-bundle path in stem_ai/detectors.py and removed drift from an invalid direct-scanner wiring pattern.
  • Restored stage_3 scoring flow in stem_ai/scanner.py after accidental regression during external edits.

[1.5.9] - 2026-05-06

Added

  • Added docs/ADVISORY_SECRET_HANDLING.md covering provider-specific environment variables, .env handling policy, endpoint restrictions, artifact redaction rules, and the no-secret-persistence boundary for advisory packets.
  • Added docs/ADVISORY_RUNTIME.md documenting the explicit --advisory call trust boundary, runtime guards, and current non-implemented adapter behavior.
  • Added docs/EXAMPLE_AUDITS.md as a surface-facing proof index for sample report artifacts, live demo behavior, and comparison expectations.
  • Added .env.example documenting supported advisory environment variables without shipping any secret values.

Changed

  • Strengthened the public README surface with PyPI install path, proof-surface links, and explicit secret-boundary notes for advisory packet export.
  • Rotated the active MICA memory layer to v1.5.9 and documented advisory secret-boundary policy in the active archive/playbook/lessons set.

Fixed

  • Advisory provider configuration now prefers provider-specific API key env vars before the generic fallback and exports the selected env-var name without exposing the secret.
  • Advisory provider request validation now rejects embedded-credential base URLs, rejects non-local plain http endpoints, and requires https for cloud-provider overrides.
  • Secret-free handoff metadata now includes endpoint-policy validation, network-mode classification, and exported env-contract metadata for downstream runners.
  • Added explicit --advisory call runtime mode with centralized redaction, adapter logging policy export, child-env allowlist reporting, and artifact pre-write sanitization for JSON/Markdown/explain outputs.

[1.5.8] - 2026-05-05

Fixed

  • Narrowed C2_dependency_pinning to real dependency-manifest surfaces so non-dependency pyproject.toml metadata lines such as name, version, readme, and keywords no longer count as loose dependencies.
  • Exempted realistic credential fixtures under test/example paths from C1_hardcoded_credentials penalties while keeping production-path sk-*, AKIA*, ghp_*, and api_key= detections active.
  • Replaced broad text-level C4 matching with AST-backed executable fail-open handler detection so string literals and detector-explanation text containing except: pass no longer trigger warnings.
  • Removed the Gradio 6 runtime warning in the Hugging Face demo by routing CSS through the correct Blocks/launch compatibility path.
  • Fixed long-standing package manifest drift so PyPI artifacts include SKILL.md, active memory/ files, and public docs/ contract files instead of shipping a code-only package surface.

Added

  • Added regression coverage for credential-fixture exemption, pyproject metadata precision, executable fail-open detection, and non-executable except: pass string immunity.

Changed

  • Improved detector honesty on final dogfooding targets: Sidrce now clears prior C1/C2/C4 false positives and moves from 52 / T1 to 62 / T2 under the corrected scanner.

[1.5.7] - 2026-05-05

Added

  • Added advisory packet self-validation via packet_contract, checking allowlist parity, snippet omission, and omission-count sanity before any provider handoff.
  • Added exported advisory contract schemas (contract_schemas) so downstream validators can consume stable input/output packet shapes without reading repository code.
  • Added secret-free provider request schema export and deterministic provider argument validation metadata under provider_request.
  • Added regression coverage for advisory contract schema export, provider request validation, advisory packet allowlist mismatch, and invalid payload-shape handling.
  • Added docs/MICA_MEMORY.md documenting active-vs-archived memory policy, mica.yaml loader responsibility, and release rotation rules.

Changed

  • Updated README, API contract, scoring rationale version markers, and release validation defaults for the v1.5.7 advisory contract-hardening release.
  • Rotated the active MICA memory layer to v1.5.7 and updated memory/mica.yaml / SKILL.md so the loader follows the active files instead of stale hard-coded memory filenames.

Fixed

  • Hardened advisory validation so malformed provider payload shapes are rejected as structured contract errors instead of causing a validator crash.

[1.5.6] - 2026-05-01

Fixed

  • Reduced CA-DIRECT/T0 hard-floor false positives from framework meta-documentation such as scoring tables, regex descriptions, advisory contracts, and diagnostic-layer labels.
  • Expanded clinical-boundary detection for phrases such as "not a medical device", "not intended for clinical use", "not clinically validated", and "does not provide clinical diagnoses".
  • Updated stale public contract, scoring rationale, release validation default, measurement-basis text, and PDF Stage 3 explanatory copy to match v1.5.5/v1.5.6 behavior.

Added

  • Added regression coverage proving real direct clinical claims still trigger the T0 floor while framework self-documentation does not.
  • Added scripts/benchmark_local10_ca_fp_impact.py and local-10 v1.5.6 CA false-positive impact artifacts.

[1.5.5] - 2026-05-01

  • Updated README: professional bio/medical AI structure, v1.5.5 badge and citation, Detection table moved to collapsible section, Advisory Contract section with enforcement rules, removed stale v1.3 references.
  • Bumped version to 1.5.5 (aligning package version with v1.5.4 code tag that was released without a version bump).

[1.5.4] - 2026-05-01

Added

  • Refined Stage 3 T3, B1, and B2 scoring from binary to three-tier:
    • T3 Changelog: 0 (absent) / +5 (exists, no bug entries) / +15 (bug-fix, patch, or security entries present).
    • B1 Data Provenance: 0 (no manifest) / +10 (manifest present) / +15 (manifest + IRB or dataset-citation language).
    • B2 Bias/Limitations: 0 (no vocabulary) / +8 (vocabulary only) / +15 (vocabulary + quantitative measurement evidence).
  • Added CHANGELOG_BUG_TERMS, DATA_SOURCE_TERMS, and BIAS_MEASUREMENT_TERMS regex patterns.
  • Added _score_changelog, _score_provenance, and _score_bias helper functions extracted from _score_stage_3.
  • Added unit tests for each three-tier scoring path (9 new test cases).
  • Added scripts/benchmark_local10_stage3_3tier_impact.py and local-10 v1.5.4 Stage 3 three-tier impact benchmark artifacts.
  • Added docs/SCORING_RATIONALE.md: formula derivation, baseline-60 convention, tier boundary justification (anchored to scoring baseline ± offsets), Stage 1–4 rationale, score-cap policy, and calibration gap disclosures.

Changed

  • Local-10 benchmark: 0 tier changes vs v1.5.3 baseline; mean score delta −0.9 (bare provenance manifests no longer earn full B1 credit without dataset citation language).

[1.5.3] - 2026-05-01

Added

  • Added Stage 2R limitation-repetition credit across README, docs, and changelog surfaces.
  • Added Stage 2R deductions for internal clinical-boundary contradictions, stale README/package version metadata, and unsupported workflow/test/CLI claims.

[1.4.5] - 2026-04-30

Added

  • Added stem_ai/provider_benchmark.py for compact provider-packet and provider-response validation benchmark records.
  • Added scripts/provider_packet_benchmark.py to export provider-budgeted packets, packet stats, packet summaries, and optional saved response-validation records without making provider API calls.

Added

  • Added provider-budgeted advisory packets capped to 40 ranked evidence findings for practical Gemini/Qwen-style context budgets.
  • Added allowed_finding_ids to advisory input packets so providers can copy exact citation IDs instead of shortening detector names.
  • Added provider_prompt_contract guidance documenting strict JSON output, exact citation-copying, no score override, and clinical/regulatory claim boundaries.
  • Added regression and release validation coverage for deterministic provider packet budgets and citation allowlists.

Changed

[1.4.0] - 2026-04-30

Added

  • Added provider-neutral ai_advisory contract support with offline validation via stem audit <repo> --advisory validate.
  • Added stem_ai/advisory_contract.py for advisory input packet construction, citation extraction, citation validation, prohibited-claim checks, and deterministic no-AI advisory output.
  • Added ASDP-inspired advisory schema and compile notes under spec/asdp/ and docs/asdp/.
  • Added v1.4.0 planning document for evidence-bound AI advisory, provider adapters, ASDP contract compilation, and local Qwen/Kimi/Unsloth future paths.
  • Added tests ensuring advisory input omits raw snippets by default, rejects unknown citations, rejects score overrides, rejects clinical/regulatory claims, and surfaces advisory validation in CLI/Markdown/explain output.

Changed

  • Established the provider-neutral advisory contract surface that later converged into the stable local CLI result schema family.

[1.3.2] - 2026-04-30

Added

  • Added stem_ai/reasoning_model.py as a deterministic diagnostic layer over the evidence ledger.

[1.3.1] - 2026-04-30

Fixed

  • Improved local-10 benchmark alignment by detecting clinical-adjacent skill-catalog surfaces such as AutoDock, nnU-Net, pydicom, drug docking, and medical imaging.
  • Excluded obvious placeholder/test credential values from the C1 penalty while keeping them visible in the evidence ledger as non-applicable evidence.

Added

  • Added local-10 control benchmark summaries and before/after comparison artifacts for the CA/C1 precision patch.

[1.3.0] - 2026-04-30

Added

  • Added v1.3 evidence ledger output with stable POSIX finding_id values, detector metadata, source file, line, snippet, match type, explanation, and optional metadata.
  • Added stdlib AST observation summary (ast_signal_summary) for assertion tests, seed settings, argparse CLI surfaces, docstrings, annotations, portable model loading, syntax errors, and fail-open handlers.
  • Added Stage 4 Reproducibility & Replication Evidence as a separate lane with replication_score, replication_tier, and stage_4_rubric.
  • Added deterministic Stage 4 detectors for containers, Makefile reproduction/evaluation targets, environment/lock files, exact pins/hashes, README reproducibility sections, checksum files, dataset/model artifact references, CITATION.cff, CLI evidence, seed evidence, and runnable examples.
  • Added stem audit ... --explain, which writes a plain-text proof trace grouped by detector and includes full finding_id values for citation by future AI layers.
  • Added v1.3 planning documents for evidence-ledger contracts, Stage 4, benchmark methodology, and deferred v1.3.1 reasoning model candidates.
  • Added audits/benchmark-v1.3/ template workspace for the 30-repository benchmark manifest, JSONL results, tier alignment summary, and false-positive/false-negative log.

Changed

  • Split detector implementation into focused modules: surface detectors, AST detectors, Stage 4 detectors, shared detector utilities, shared patterns, and evidence dataclasses.
  • Kept AST and Stage 4 outputs observation-only for v1.3.0; the established final score formula remains unchanged.
  • Updated README to describe Stage 4, --explain, AST observation, replication tiers, and evidence-ledger artifacts.

Fixed

  • Closed evidence-ledger coverage gaps for scored Stage 3 and C1-C4 components.
  • Improved AST detection for direct ArgumentParser() imports and mock-style assertion calls.
  • Removed duplicated detector constants from scanner internals by centralizing shared patterns.

[1.2.0] - 2026-04-30

Changed

  • Repositioned as a deterministic evidence-surface scanner rather than a trust auditor; README subtitle and Core Features updated accordingly.
  • T0–T4 labels changed from trust verdicts to triage / review-priority tiers with explicit scope statements.
  • Added "What STEM Actually Measures" table to README — each score component now documents its physical detection method.
  • Renamed "Stage 1 — README Intent Analysis" to "Stage 1 — README Evidence Signal" in PDF reports.
  • Measurement Boundary section in README replaces Boundary and explicitly states that scores reflect observable signals, not clinical safety or author intent.
  • pyproject.toml description updated; [demo] extra dependencies cleaned up (removes outdated pins).

Fixed

  • Removed bare treatment from CA-DIRECT terms; replaced with phrase-level patterns treatment recommendation and treatment guidance to reduce false positives on bioinformatics data-processing contexts.
  • Removed bare population from B2 bias/limitations terms; the word alone is a false positive in population-genetics contexts.

Added

  • measurement_basis field added to JSON output documenting the detection method for each scored component.

[1.1.3] - 2026-04-29

Fixed

  • Corrected Python dependency-pinning detection so loose ranges such as >=, <=, ~=, <, and > no longer pass C2 as exact pins.
  • Added deterministic CA severity classification for LOCAL_ANALYSIS (CA-DIRECT, CA-INDIRECT, none) and activated the T0 hard-floor cap for unbounded direct clinical claims.
  • Added a T2 score cap for clinical-adjacent repositories that lack an explicit non-clinical/non-diagnostic boundary.
  • Rebalanced Stage 3 scoring to normalize the full 80-point T/B rubric to 100, restoring attainable T3/T4 ranges.
  • Fixed B1 max-score mismatch and added local B2 bias/limitations and B3 COI/funding evidence detection.
  • Removed repository-specific deprecated-path scanning and replaced it with generic deprecated/legacy/archive directory scanning.
  • Hardened fail-open exception detection for CRLF code paths.
  • Prevented fallback PDF text overflow when reportlab is unavailable.
  • Bounded reportlab style cache growth for long-running Gradio sessions.
  • Added CLI --version and safer Gradio report-level fallback handling.
  • Made the skill validator select the latest core spec and MICA archive instead of hard-coding v1.1.2.
