[migration-approved]
The init-handler was non-idempotent. A second click on "Neu initialisieren
in Grenzen" inserted every engine-suggested mitigation a second time —
e.g. the Bremsscheibe project ended up with 5 (hazard_id, name) duplicate
pairs (HMI-Usability-Pruefung, Eindeutiges visuelles Feedback,
Betriebsarten-Anzeige, Sicher begrenzter Bewegungsbereich, …). 45 such
duplicates accumulated across all projects.
Migration 030_iace_mitigation_unique.sql:
1. Picks one winning row per (hazard_id, name) using a stable rank:
is_relevant DESC (expert decision wins over engine default)
status DESC (verified > implemented > planned)
created_at DESC (newest beats older on otherwise-equal rows)
and deletes the losers (Bremsscheibe: 5 rows; total: 45).
2. Adds UNIQUE constraint iace_mitigations_hazard_name_uniq
(hazard_id, name).
Store-Layer (CreateMitigation):
INSERT … ON CONFLICT (hazard_id, name) DO NOTHING RETURNING id.
pgx.ErrNoRows from RETURNING → look up the existing row and return that.
Callers (engine init + manual add) always get a usable Mitigation; the
second click is silently swallowed instead of failing.
Frontend dedupe in groupByTitle stays — it covers any pre-existing
duplicates that survived the migration in edge cases (multi-row write
in flight, etc.). With the UNIQUE constraint live, the in-memory
dedupe is a belt-and-suspenders safety net rather than the load-bearing
mechanism.

ai-compliance-sdk
Go/Gin service providing AI-Act compliance analysis: iACE impact assessments, UCCA rules engine, hazard library, training/academy, audit, escalation, portfolio, RBAC, RAG, whistleblower, workshop.
Port: 8090 → exposed 8093 (container: bp-compliance-ai-sdk)
Stack: Go 1.24, Gin, pgx, Postgres.

Clean-arch refactor is complete:

Linting (Phase 5): .golangci.yml added — run golangci-lint run --timeout 5m ./....
Run locally
cd ai-compliance-sdk
go mod download
export COMPLIANCE_DATABASE_URL=...
go run ./cmd/server
Tests
go test -race -cover ./...
golangci-lint run --timeout 5m ./...
Co-located *_test.go, table-driven. Repo layer uses testcontainers-go (or the compose Postgres) — no SQL mocks.
Public API surface
Handlers under internal/api/handlers/ (8 sub-resource files). Health at GET /health. iACE, UCCA, training, academy, portfolio, escalation, audit, rag, whistleblower, workshop subresources. Every route is a contract.
