- Domain-gate ~15 foreign machine classes (pool, amusement, paint booth,
tank farm, reactor, lathe/chips, saw, film/carton, robot, mobile cab,
asbestos, playground swing) in pattern_domain_gates.go so ungated hazard
patterns stop leaking into unrelated machines; matching emit keywords
added in keyword_dictionary.go (gate+emit share one vocabulary).
- Extend the cross-domain precision guard to 6 machine classes (press,
cobot, motor, welding + the 2 GTs) with per-case homeDomains, so a
machine's own domain terms are never flagged. GT coverage stays 100%.
- Reconcile the fine-grained norm machine-type vocabulary (455 keys) with
the 68 canonical dropdown keys via canonicalMachineType() family folding
in matchNorm — welding 0->17, robotics_cobot 0->6, press 8->13,
circular_saw 1->35 machine-specific C-norms. Pattern gating left strict.
- Fix initialize?force=true summary index-shift that mislabeled counts
(reported matched-patterns as "hazards"); now uses named step vars.

Engine precision (stop foreign-machine patterns leaking into a project):
- Wire project.MachineType into the engine machine-type gate (empty input no
longer fires every machine class — press/cnc/excavator/crane/medical...).
- Capability-domain gating extended by 7 domains (outdoor, ventilation,
machining, bulk, palletizer, playground, fitness) so domain-specific hazards
only fire when the narrative names that domain; emitted via keyword_dictionary.
- Relevance backstop moved into iace (single gating contract, testable), and its
dominant false-anchor class removed (a long pattern word no longer matches a
short common token; prepositions/leitung added to the generic stoplist).
- New guard tests: TestCrossDomainPrecision (full pipeline, 0 foreign per GT) and
TestPatternReachability now asserts 0 dead patterns. Both GTs keep coverage 1.0.
Reachability fix: the 51 dead patterns required electrical/pneumatic/hydraulic
tags nothing produced — renamed to the canonical electrical_energy/
pneumatic_pressure/hydraulic_pressure/hydraulic_part.
Component review (negation is best-effort + expert-correctable):
- Parser surfaces negated components (ComponentMatch.Negated) instead of dropping
them; negated contribute no tags/energy → no phantom hazards.
- presence_status (vorhanden|nicht_vorhanden|geloescht) + ce_marked on components;
only `vorhanden` feed matching. CE+safety-relevant flags the PL/SIL obligation.
- Force re-seed preserves the expert's component decisions instead of wiping them.
- Tag-based component→hazard assignment (was: all on the first component).
- Negation-aware narrative parsing ("keine Pneumatik" no longer extracts it).
Local-dev DB: ai-sdk sets search_path=compliance,core,public; reconcile migrations
152-156 bring the consolidated local iace tables to the current schema + add the
presence_status/ce_marked columns. Machine-type vocabulary endpoint for the form.

Observed on a real Kistenhubgeraet (lift) project: generic mechanical patterns
(e.g. HP1000 "Quetschen Arm zwischen Pressenteilen") carry NO machine type and
only generic tags (crush_point, rotating_part), so they fired for a lift; the
narrow domain-gate terms missed their press/welding/glass wording.
Broadens domainGateTerms (pressenteil, pressraum, blechbearbeitung,
punktschweiss, schweisselektrod, elektrodenspalt) and adds a dom_glass domain
(glasschneid/glasbearbeitung/...) with its emit keywords. New test pins that the
four observed leakers now require a dom_* tag. Ghost=0, Leakage=0, coverage held
on both GTs.

PROBLEM: Cobot-Projekt hatte 52 Pressen-Hazards weil Keywords wie
"stempel" und "stoessel" ohne Maschinentyp-Kontext matchten.
FIX an 3 Stellen:
1. KeywordEntry.MachineTypes — Pressen-Keywords nur fuer press/*_press
2. ParseNarrative(text, machineType) — Parser laedt Maschinentyp aus Projekt
3. HazardPattern.MachineTypes — Pressen-Patterns (HP045-HP058) nur fuer Pressen
Verhindert zukuenftig falsche Zuordnungen bei neuen Kundenprojekten.
