Purpose

This FS specifies the implementation of the GenAI gateway to satisfy `HYD2-URS-GENAI-001` v1.2. The gateway exposes vendor LLMs (Anthropic Claude, OpenAI GPT) through site-validated per-use-case templates and guard-rails. Per-use-case EU AI Act classification is implemented to apply Art. 9–17 obligations where the use case is Annex I or Annex III high-risk, and Art. 50 transparency obligations universally.

## 2. Scope

Site-developed Python gateway on K8s wrapping Anthropic + OpenAI APIs; per-use-case prompt templates (Cat 5 sub-components); PHI / PII guard-rails (input redaction + output filtering); prompt-injection + jailbreak defences; retrieval-grounding pipeline; hallucination detection; output watermarking; cost + token-budget controls; response-logging; consumer-facing API behind site API Gateway; Okta SSO + MFA; integrations with Splunk SIEM, Application Portfolio, validated GitLab. Per-use-case EU AI Act classification gate. Per-use-case Art. 11 + Annex IV pack for high-risk use cases. GDPR Art. 35 DPIA registry. Vendor DPA / BAA on file. Vendor GPAI compliance evidence registry.

| FS-COST-03 | URS-COST-03 | Cost-anomaly detector publishes alert to PagerDuty + System Owner on > 3σ spike. |
| FS-CACHE-01 | URS-CACHE-01 | Cache key = SHA-256 over `(prompt_template_version, prompt_inputs, retrieval_corpus_version, model, model_version, use_case_id)`; cache poisoning by replay infeasible. |
| FS-CACHE-02 | URS-CACHE-02 | Cache entries cosign-signed at write; verification on read; signature failure → cache miss + alert. |
| FS-CACHE-03 | URS-CACHE-03 | Per-use-case `cache_ttl_seconds` in `use_case_config.yaml`; upper bound = corpus freshness SLA. |
| FS-HITL-01 | URS-HITL-01 | Consumer SDK enforces `human_in_loop=true` flag for regulated-decision use cases; downstream review record required before consumption. |
| FS-HITL-02 | URS-HITL-02 | Response header `X-AI-Generated-Content: true` per EU AI Act Art. 50; consumer SDK propagates to end-user UI for display. |
| FS-HITL-03 | URS-HITL-03 | Human Oversight Operator UI (Grafana dashboard `hyd2-genai-ho`) for high-risk use cases; halt API `POST /use_case/{id}/suspend`. |
| FS-HITL-04 | URS-HITL-04 | Consumer SDK helper `require_human_approval()` blocks downstream consumption until `human_approval_record_id` is captured; record stored in consumer-side audit + referenced via webhook to gateway. |

### 4.1 Cross-System Integration (M-XSYS)

| FS ID | URS ID | Specification |
|---|---|---|
| FS-XSYS-AD-01 | URS-XSYS-AD-01 | Identity integration with `QTZ-URS-AD-001`: OIDC via Entra ID with workload-identity federation for service-to-service. Conditional-access binding to policy `AI-Platform Conditional Access (FIDO2 + device-compliance + risk-based step-up)`. SIEM forwarding via syslog (RFC 5424) to Splunk index `gxp-authn` within 5 minutes; SCIM provisioning where the protocol is SAML/OIDC; break-glass accounts gated by CyberArk PAM per AD URS-PAM-* with 24 h password-rotation and dual-witness check-out. |
| FS-XSYS-BAK-01 | URS-XSYS-BAK-01 | Backup integration per `AUR-URS-BACKUP-001`: Veeam Application-Aware processing with PostgreSQL pg_basebackup + WAL for the gateway audit store and use-case registry plus object-replica for prompt-evidence packs and Annex IV artefacts; tier classification = T1; RPO ≤ 4 h; RTO ≤ 4 BH; immutable cloud-tier copy in S3 Object Lock Compliance mode (geo-replicated); air-gap LTO-9 monthly rotation; monthly QA-witnessed restore test per AUR-FS-BACKUP-001 procedure; restore-certificate quality records retained ≥ 25 y in the eQMS. |


### 4.2 Cross-System Integration — LMS handover (M-XINT-LMS)

| FS ID | URS ID | Specification |
|---|---|---|
| FS-XINT-LMS-01 | URS-XINT-LMS-01 | LMS-competence adapter `<sys>-LMS-CLIENT-1.x` performs `GET /lms/competence/{user_id}?curriculum=...` over mTLS + Entra workload-identity; cache TTL per system (12-24 h); on `current=false` the consumer blocks the gated action and records `lms_lapse_user={user_id}` in the consumer audit trail; periodic reconciliation job verifies that no gated action proceeded with a lapsed competence. |

## 5. Configuration Items (CI)

| CI | Item | Value |
|---|---|---|
| CI-01 | Use-case approval | 4-of-4 (QA + Privacy + Reg + AI Lead); 5-of-5 for Annex I (+ Conformity Coordinator) |
| CI-02 | Vendor-LLM version | pinned per use case |
| CI-03 | Guard-rail | input + output enabled per use case |
| CI-04 | Audit retention | ≥ 25 y (Splunk frozen-index) + ≥ 10 y (Art. 18 cold archive) |
| CI-05 | Prompt-injection detector | Lakera-style classifier; OQ recall ≥ 95% |
| CI-06 | DPIA URN | mandatory for personal-data use cases |
| CI-07 | Okta MFA-required group | `hyd2-genai-prod` |
| CI-08 | Vault rotation cadence | 90 days |
| CI-09 | HPA pod range | 4 – 32 |
| CI-10 | Classification gate | runs at REVIEW → CLASSIFIED transition |
| CI-11 | Art. 73 clocks | 15 d / 10 d / 2 d |
| CI-12 | Annex IV pack base path | `s3://hyd2-aiact-techdoc/` |
| CI-13 | Cache key fields | `(prompt_template_version, prompt_inputs, retrieval_corpus_version, model, model_version, use_case_id)` |
| CI-14 | Cost-anomaly threshold | > 3σ over 7-day baseline |
| CI-15 | EU-region preferred vendor endpoints | per `vendor_endpoint_router.py` |

## 6. Risks (FS-level)

Implementation-level risks (URS § 9 RA documents R-01..R-20). FS-side additional risks:

- Lakera classifier model drift → mitigation: monthly evaluation + threshold-recalibration
- Vendor API key rotation failure → mitigation: Vault rotation monitoring + alert on stale key
- Use-case-registry race condition on concurrent approval → mitigation: optimistic locking with version field
- Classification-gate bypass via direct DB write → mitigation: DB role denies Classifier-bypass routes; OQ test attempts bypass
- Retrieval-corpus version drift between use cases sharing corpus → mitigation: per-use-case pinning + change notification
- Watermark stripping by downstream UI → mitigation: SDK enforcement + downstream-UI audit
- Cost-budget bypass via parallel calls → mitigation: budget enforcement at gateway-wide level + per-consumer secondary cap
- Art. 73 clock miscalculation across timezones → mitigation: UTC internal + TZ display

## 9. Implementation Risk Register

The risks below are properties of the **implementation** (configuration, integration, runtime, operation) of this system, not properties of the user requirements themselves. They are surfaced here for input to the formal Risk Assessment deliverable (FMEA / HAZOP — separate document `<DOC-PREFIX>-RA-NN`). Per-requirement GxP-criticality (R1/R2/R3) remains on each URS requirement and is not duplicated here.

**Origin:** transferred from the URS § 9 Top-level Risks section as part of v1.3 corpus restructuring (LLM Council verdict + user directive 2026-05-13). The transferred content is verbatim from URS; future review may re-frame entries to FS-implementation language or re-distribute to the formal RA artefact.

| R-02 | PHI / PII leak to vendor LLM | Low | Critical | URS-GR-01, URS-VND-01, URS-DI-06, URS-RED-01..03 |
| R-03 | Silent vendor-LLM-version change | Medium | High | URS-VND-02, URS-UC-04 |
| R-04 | Prompt-injection / jailbreak producing off-policy output | Medium | High | URS-PI-01..05, URS-SEC-02, URS-SEC-06 |
| R-05 | Audit-trail tampering | Low | Critical | URS-AUD-02, URS-INT-SIEM-01 |
| R-06 | Use-case drift from approved intended use | Medium | High | URS-UC-01, URS-PR-01..03 |
| R-07 | EU AI Act Art. 50 transparency non-compliance (unlabelled AI content) | Medium | Medium | URS-HITL-02, URS-WM-01..03 |
