They must never + be inferred from user disability, health, or other sensitive personal + attributes; `accessibility_bonus` stays `0` unless tenant DPIA/privacy review + and user-facing notice approve changing it. + +Changing `weighted_v1` semantics is not allowed. Any ML or tenant-specific +strategy must be introduced as a new algorithm version and must pass parity +fixtures against `weighted_v1` before rollout. + +## Config Boundary + +The Rust module registry exposes a JSON Schema for `recommendations` through the +existing admin module config editor. Values are persisted under +`module.recommendations.config.*` and loaded by the recommendations API with +legacy-safe defaults. The `explain` and `profile_safe_mode` settings are +reserved, fail-closed fields: attempts to set them to `false` are rejected by +schema and ignored by runtime loading. + +`fop_pipeline_v1` uses the fop-pipeline JSON/HTTP boundary: +`POST {pipeline_endpoint}/pipeline/{pipeline_name}/run`. ParkHub sends the +candidate slots, weights, `profile_safe_mode`, explanation requirement, and +`fallback_algorithm=weighted_v1`. The adapter only accepts local, `.test`, or +Kubernetes service hosts by default and records whether the pipeline was +attempted, succeeded, or fell back. + +The response continues to include reasons and badges. Shared parity fixtures +live under `docs/recommendation-engine-fixtures/` and are the contract for Rust, +PHP, and any future fop-pipeline adapter. `profile_safe_mode` stays enabled by +default and is reserved as the privacy gate for the future fop-pipeline adapter. +The stats endpoint also emits a machine-readable legal boundary: +`legal_review_required=true`, `attorney_review_status=required_before_customer_wording`, +and `execution_allowed=false` for generated/public profiling or legal wording. + +Every served recommendation batch includes a `recommendation_id` and writes a +best-effort `RecommendationServed` audit event. The event stores the algorithm, +SHA-256 config hash, SHA-256 weights hash, `profile_safe_mode`, `explain`, +adapter status, candidate slot IDs, scores, reason badges, reasons, and the legal +boundary. This is the trace key for later acceptance/rejection linkage and audit +export. + +## Compliance Boundary + +This is engineering compliance, not legal advice. For German/EU/international +use, the recommendation surface must keep: + +- data minimization: no sensitive categories, location history beyond parking + usage, or unrelated profile attributes in the score inputs; +- explainability: every score must keep a reason or badge that can be audited; +- operator control: weight changes must be authenticated, audited, and reversible; +- security evidence: SBOM/provenance/vulnerability handling remains part of the + ParkHub CI/CD baseline before business rollout; +- legal review: public ToS/privacy/profiling wording must go through `fop legal` + plus attorney review before being treated as customer-ready. + +`fop legal catalog` currently marks the local Claude-for-Legal catalog as +reference-only with attorney review and human signoff required, and execution +disabled. ParkHub mirrors that boundary in recommendation stats so operators can +see that compliance support is present but not a substitute for counsel. + +2026 compliance posture gates before business rollout: + +- SBOM, provenance, image digest, and VEX/vulnerability evidence attached to the + ParkHub Rust/PHP release artifacts; +- documented vulnerability disclosure and security update process; +- audit evidence retention for module config changes and served + `RecommendationServed` decisions; +- CRA/NIS2/AI Act/GDPR milestone tracking in the fop task board before + customer-facing profiling language ships. + +Relevant current public references: + +- European Commission, GDPR data protection by design and by default: + https://commission.europa.eu/law/law-topic/data-protection/rules-business-and-organisations/obligations/what-does-data-protection-design-and-default-mean_en +- European Commission, Cyber Resilience Act: + https://digital-strategy.ec.europa.eu/en/policies/cyber-resilience-act +- European Commission, CRA summary: + https://digital-strategy.ec.europa.eu/en/policies/cra-summary +- European Commission, NIS2 Directive overview: + https://digital-strategy.ec.europa.eu/en/policies/nis2-directive +- European Commission, AI Act transparency guidance: + https://digital-strategy.ec.europa.eu/en/faqs/guidelines-and-code-practice-transparent-ai-systems +- BSI IT-Grundschutz-Kompendium: + https://www.bsi.bund.de/DE/Themen/Unternehmen-und-Organisationen/Standards-und-Zertifizierung/IT-Grundschutz/IT-Grundschutz-Kompendium/it-grundschutz-kompendium_node.html + +## Legal Review Packet + +`fop legal` can draft the supporting documents, but the generated text is not a +shipping approval.
