The generic hot-surface patterns HP016 (high_temperature) and HP018 (actuator
burn) fire for dishwashers via broad tags and duplicate the precise warewashing
pattern HP2201 (Boiler/Tank/Spuelkammer). Suppress HP016/HP018 only when
dom_warewashing is present, so the specific pattern wins and the duplicate is
dropped. Scoped to the domain tag -> Kistenhub/Bremse and every non-warewashing
machine keep the generic patterns unchanged.
Warewashing recall stays 100% (25/25), precision 90% -> 92.6% (2 dupes removed).
Bremse 26 pins and Kistenhub benchmark unaffected.

Class C (phase-aware, generic EN ISO 14120). A contact/entanglement hazard from
a moving part is removed during NORMAL operation when the part is behind an
interlocked guard; it remains only when the guard is open (maintenance/cleaning).
- New HazardPattern.GuardableByEnclosure flag; set on HP096 (friction at
rotating surfaces) and HP101 (entanglement of hair/clothing).
- Narrative emits interlocked_enclosure for an interlocked door/hood.
- pattern_enclosure.go: suppressedByEnclosure (drop in normal-op-only contexts)
+ guardedLifecycles (re-scope to maintenance/cleaning).
- GT #3 gains the maintenance-phase entanglement/friction rows.
Generic + regression-safe: machines that do not emit interlocked_enclosure are
unaffected. GT #3 recall 80% -> 82.4%, one false positive removed (Aufwickeln).
Kistenhub 97.1% and all 26 Bremse pinned mappings unchanged.

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.

Phase 16 of the Klaerungen / risk-assessment polish. Sources from
EN ISO 12100 Anhang B Tabelle B.1 are now first-class:
A) HazardPattern.ISO12100Section identifier (string), persisted only as
the section number (e.g. "6.3.5.5") — not the norm text. Keeps the
library urheberrechtlich neutral (DIN/Beuth license). 57 patterns
labeled today; rest will follow on touch.
B) Category split per ISO 12100 Nr. 4 vs Nr. 5:
- 16 patterns reclassified noise_vibration -> noise_hazard
- 7 patterns reclassified noise_vibration -> vibration_hazard
- 1 pattern (HP228 UV-/Laermexposition) kept multi-cat
acceptableMeasureCategories now accepts both new aliases plus the
legacy noise_vibration. Coverage test recognises both as valid.
C) 5 new ISO-12100-Annex-B gap patterns (HP1900-HP1904):
- HP1900 Vakuum-Verletzung (6.3.5.5)
- HP1901 Federenergie / elastische Elemente (6.2.10)
- HP1902 Rutschen/Stolpern auf rauer Oberflaeche (6.3.5.6)
- HP1903 Hochdruckinjektion (6.3.5.4) — includes clarifying
"no hand-locating of leaks" question
- HP1904 Ersticken durch Brustkorbquetschung (6.3.5.2)
The library now mirrors the ISO 12100 Annex B structure for the gaps
the Bremse benchmark surfaced.

Drei nachhaltige Verbesserungen, getrieben durch die Bremse-Benchmark-
Faelle GT 1.4, GT 1.30 und GT 7.4. Die Engine erfindet weiterhin
keine Fachmann-Kommentare — Kommentare bleiben aus, weil sie ein
Verstaendnis der konkreten Anlage erfordern, das die Engine nicht
hat. Statt dessen liefert die Engine norm-basierte Klaerungsfragen
und ein praeziseres Pattern-Vokabular.
A) HazardPattern.ClarificationQuestionsDE — neues optionales Feld:
- Pattern hinterlegt prueffaehige Fragen, die der Bediener mit dem
Anlagenbauer abklaert. Beispiele:
- HP1640: "Liegt ein Pruefprotokoll nach EN 60204-1 vor?"
- HP1666: "Ist die WZM als CE-konformes Subsystem integriert?"
- HP1604: "Ist DCS am Roboter konfiguriert und validiert?"
- Init-Handler haengt die Fragen an Hazard.Description an mit dem
Marker "Mit Anlagenbauer zu klaeren:". Kein DB-Schema-Aenderungs-
bedarf.
- 11 Patterns mit Klaerungsfragen versehen (HP1602, HP1604, HP1611,
HP1612, HP1620, HP1622, HP1637, HP1640, HP1641, HP1666, HP1685).
B) HP1632 "Bersten druckbeaufschlagter Pneumatik-Komponente" — neues
Pattern, semantisch DISTINKT zu HP1630 "Abspringen":
- Bersten = Material-/Druckversagen der Komponente, Mediumaustritt
- Abspringen = Verbindung loest sich, Peitscheneffekt
Bremse-Benchmark GT 1.4 sprach von Bersten, HP1630 nur von
Abspringen — ein 66%-Frontend-Match war eine Sackgasse. Mit
HP1632 feuert die Engine ein eigenes Hazard, das auf GT 1.4
einen sauberen Volltreffer liefert.
C) HP1637 "Einatmen von KSS-Aerosolen" — Massnahmen vervollstaendigt:
Vorher nur M141 (Sicherheitszeichen), neu zusaetzlich M405 (KSS-
Aerosolabsaugung), M418 (AGW-Ueberwachung), M526 (WZM-Tueren
geschlossen waehrend Bearbeitung), M408 (Hautschutzplan).
Klaerungsfrage: "Wurde die Aerosolkonzentration nach Bearbeitungs-
ende messtechnisch ermittelt und mit dem AGW verglichen?"

Each hazard now gets measures from its SOURCE PATTERN first
(SuggestedMeasureIDs), then category fallback for remaining slots.
Previously all mechanical hazards got the same generic top-5 measures
(Gefahrstelle eliminieren, Sicherheitsabstaende, Scharfe Kanten...).
Now a KSS-Schlauch hazard gets M420 (Druckfeste Auslegung) first.
SuggestedMeasureIDs added to PatternMatch struct and passed through
from pattern definition to hazard creation to measure assignment.

- ApplicableLifecycles field in HazardPattern: patterns now declare which
lifecycle phases the hazard applies to (Output, not just filter)
- Init handler writes first applicable lifecycle into Hazard.LifecyclePhase
- Robot cell patterns HP1600-1601 broadened: "Betrieb, Einrichten, Reinigung,
Wartung, Fehlersuche" instead of only "Teach-Betrieb"
- All robot cell patterns get ApplicableLifecycles for proper phase display

Neues Feld "Einsatzbereich" auf Interview-Seite (Sektion 7) mit 15 Branchen.
Pattern Engine bekommt MachineTypes aus MatchInput → branchenfremde Patterns
(Medizin, Aufzug, Bau etc.) feuern nur wenn die Branche ausgewählt ist.
Refactoring: iace_handler_init.go aufgeteilt in init + init_helpers (LOC-Limit).

Split: food_pkg aufgeteilt in food_processing + packaging
