Phase 17 of the risk-assessment polish. Two pieces:
A) PLr per EN ISO 13849-1 Anhang A (Risikograph)
- HazardPattern.DefaultAvoidability (1 = P1, 2 = P2). Optional;
defaults to P1 if unset (conservative — operator can raise after
review).
- ComputePLr(s,f,p) implements the canonical 8-leaf binary tree
(S1F1P1 -> a, ..., S2F2P2 -> e). Pinned by 8 table-driven tests.
- SeverityToS / ExposureToF map the existing 1-5 fields to the
binary S/F at the documented threshold (3).
- At project initialise, every hazard's Description is appended
with "Risikograph EN ISO 13849-1 (Anhang A): S2 · F1 · P1 -> PLr c"
so the audit value is visible without leaving the hazard view.
- PatternMatch carries DefaultAvoidability so the init handler can
pick it up without a second pattern lookup.
B) Methoden-Kopf am Bericht
- GET /clarifications.html now opens with a standardised methodology
block: ISO 12100 Anhang B (hazard ID) + ISO 13849-1 Anhang A
(PLr graph) + ISO 12100 6.2/6.3/6.4 (reduction hierarchy). Same
wording on every export, ready for the Anlagenbauer-Uebergabe.
- Only norm identifiers — no norm text reproduced.
C) ISO12100Section in Hazard Description
- When a pattern is labeled with ISO12100Section, the hazard
description gets a "Klassifikation: EN ISO 12100 Anhang B,
Abschnitt 6.3.5.4" suffix. Provenance for the auditor.

[migration-approved]
Three pieces complete the Klaerungen lifecycle:
1. Migration 028: iace_clarifications + iace_clarification_comments +
iace_clarification_history. Deterministic clarification_key
(UNIQUE per project) so engine re-inits don't lose answers.
History table logs every status/answer transition. The previous
JSONB-in-metadata storage is kept as read-only fallback for
pre-migration projects until a one-shot upcopy script runs.
2. Multi-User-Workflow:
- assigned_to field on every clarification (free-text user kuerzel
for now; an FK to users can be added in a follow-up).
- Comment thread per clarification (POST .../comment, GET
.../detail returns the thread).
- Status-history log written by UpsertClarification when the
status or answer actually changes.
- Frontend Modal: Zugewiesen-an + Bearbeiter fields, comment
thread with inline post, collapsible history section.
3. PDF-Export via print-friendly HTML:
- GET /clarifications.html returns a standalone A4-styled
document with status badges, norm references, affected hazards
and a signature row at the bottom. The Bediener opens the link
and uses Strg-P / Cmd-P to save as PDF. No server-side PDF
dependency added.
- Frontend "PDF / Druck" button next to CSV export.
Backend:
- internal/iace/store_clarifications.go: UpsertClarification,
ListClarificationsForProject, GetClarificationByKey,
AddClarificationComment, ListClarificationComments,
ListClarificationHistory.
- internal/api/handlers/iace_handler_clarifications.go:
- AnswerClarification now writes the SQL row, falls back to legacy
JSONB read on list.
- PostClarificationComment, ListClarificationDetail,
ExportClarificationsHTML added.
Migration must be applied manually on Mac Mini and prod via
psql -f /migrations/028_iace_clarifications.sql — pattern as in
scripts/apply_*_migration.sh.

Three pieces complete the Klaerungen UX:
1. Sidebar-Counter: layout.tsx polls /clarifications and shows a
colored open-count badge on the "Klaerungen" nav item. Refreshes
whenever the user changes route.
2. CSV-Export: new backend endpoint
GET /sdk/v1/iace/projects/:id/clarifications.csv produces a UTF-8-
BOM-prefixed semicolon-separated CSV (Excel-friendly) with ID,
Quelle, Kategorie, Frage, Status, Antwort, Begruendung, Bearbeiter,
answered_at, anzahl Gefaehrdungen, Gefaehrdungs-Namen, Norm-Refs.
Frontend Klaerungen-Seite bekommt einen "CSV-Export"-Button.
3. Hazard-Banner statt Fragentext im Benchmark-Detail: the previous
bulleted clarification list was duplicated across 48 hazards for a
single FANUC question. Phase 2 replaces it with a compact status
badge — "N offene Klaerung(en) — Klaerungen-Seite oeffnen" (orange)
or "Alle N Klaerungen beantwortet" (green) with a direct link.
Backend cleanup: iace_handler_init.go no longer appends the "Mit
Anlagenbauer zu klaeren" block to Hazard.Description. The description
stays focused on the scenario; clarifications live in the dedicated
endpoint and answers persist across re-inits via project.metadata.
The aggregated "Referenzierte Normen" line on the hazard is kept.

New page "Klaerungen" between Massnahmen and Verifikation.
Backend:
- internal/iace/clarifications.go: Clarification struct + ClarificationAnswer +
BuildProjectClarifications() — aggregates pattern-level + manufacturer-
level questions from collectAllPatterns + GetManufacturerSafetyFeatures.
Deterministic IDs ("pattern:HP1640:0", "manuf:fanuc:dual-check-safety-dcs:1")
so persisted answers survive every re-init.
- internal/api/handlers/iace_handler_clarifications.go:
- GET /projects/:id/clarifications returns aggregated list with affected
hazard names + persisted answer state, sorted (open first).
- POST /projects/:id/clarifications/:cid/answer writes status/answer/
reasoning/answered_by/answered_at to project.metadata.clarification_-
answers — no DB schema change.
Frontend:
- admin-compliance/app/sdk/iace/layout.tsx: new "Klaerungen" nav item.
- app/sdk/iace/[projectId]/clarifications/page.tsx: table grouped by
source (FANUC / Pattern HP1640 / …), Filter Offen/Beantwortet/Alle,
search field, Antwort-Modal with status/answer/Begruendung/Bearbeiter.
A clarification answered once applies to ALL referenced hazards — the
operator no longer has to answer the same FANUC DCS question on 48
mechanical hazards individually.
