The May-built OSHA distance library (minimum_distances.go, 29 CFR 1910,
US public domain) was dead code — zero callers, no route, no test, while
the mm values that actually appear in measures are independent hand-prose
(some carrying ISO 13854/13857 values, not OSHA).
This surfaces it without touching the measures response contract:
- GET /iace/minimum-distances (+ ?measure_id=) returns the distances, the
curated measure→distance link table and the licensing note.
- AllMeasureDistanceLinks/MinimumDistancesForMeasure resolve only the
defensible links (M600 value_source; M254/M065 public-domain crossref to
ISO), with the relation made explicit so the join stays honest.
- architecture.go lists the OSHA library so it shows in the audit explainer.
- Tests: inch→mm conversion + license completeness, link integrity, and a
consistency test pinning that a value_source measure's prose still
matches the OSHA source (codifies the audit finding as a regression gate).

Adds an auditor-facing view of the IACE engine: a clickable 10-stage
pipeline flow (Grenzen-Formular → ParseNarrative → Pattern-Gates →
Relevanz → Caps → Gefährdungen → Maßnahmen → Risiko → Normen → Matrix),
plus live library counts, the data-source/license register (incl. the
DIN/Beuth + DGUV exclusions), and the norm-matching logic that reconciles
DIN/ISO/OSHA machine-type vocabulary via canonicalMachineType folding.
Backend: BuildArchitecture() with LIVE counts so the diagram can never
drift; GET /iace/architecture; collectAllNorms() extracted from
SuggestNorms as the single source of truth for the norm-library count.
Frontend: useArchitecture hook + page + new IACE nav tab.
