Previously each curve file stored x in whatever convention the vendor
used (per-element Nm³/h for Jäger/GVA, per-element Sm³/h for PIK/PRK,
per-m² for Aerostrip). That meant the diffuser physics couldn't read
the data uniformly — selecting Aerostrip vs Jäger would feed wildly
different axes to the same interpolator.
All five curves now use the same canonical X: specific air flux in
Nm³/(h·m² membrane). Y stays SSOTR in g O₂/(Nm³·m); coverage % is the
parametric key.
Per-file conversions:
- jaeger-jetflex-td-65-2-g-epdm-1000: x divided by 0.18 m² perforated
area (stated on the data sheet).
- gva-elastox-r: x divided by 0.18 m² placeholder mirroring Jäger
TD-65 (no real GVA sheet exists — see _meta note).
- aerostrip-phoenix: native already in Nm³/(h·m²) — no x change. _meta
area normalised to 1.0 m² per "element" so users set `elements` =
total installed membrane area in m².
- pik300, prk300 (Sulzer ABS 300 mm disc): native was Sm³/h/disc on
X and g O₂/(Sm³·m) on Y. Converted to canonical Nm³ basis (DIN-1343)
by X × 0.9319 / 0.07, Y × 1.0732. Each disc = 0.07 m² membrane.
Supplier naming fixed: pikprk → sulzer, aquaconsult → aquaconsult-entec.
PIK = perforated EPDM, PRK = perforated PUR.
Config schema: new diffuser.membraneAreaPerElement field (nullable,
default null) so a node can override the curve's stored area. When
null, specificClass reads _meta.membraneArea_m2_per_element from the
resolved curve.
246/246 generalFunctions tests still pass.

Two related changes bundled together because the diffuser curve files
only make sense once the registry namespace they live in exists.
src/registry — new asset-metadata resolver:
- AssetResolver with synchronous resolve(namespace, id) + lazy cache,
async refresh() for future remote pulls.
- FileBackend (per-id or single-file layouts, case-insensitive) and a
stub HttpBackend (disabled unless EVOLV_ASSET_REMOTE=1).
- Namespaces: curves, menu, monsterSamples, monsterSpecs, units. Menu
namespace re-keys by inner softwareType + filename so editors that
pass either string resolve to the same tree.
- README explains how to add a namespace.
- AssetCategoryManager (datasets/assetData/index.js) becomes a thin
facade over the resolver so existing consumers don't move.
- 246/246 tests pass — including the 39-test registry suite.
datasets/assetData — file moves + new diffuser data:
- modelData/*.json deleted; curves/*.json is the canonical home.
- New diffuser.json menu tree with GVA, Jäger, Aquaconsult/Entec,
PIK/PRK suppliers.
- gva-elastox-r.json migrated from the inline _loadSpecs hardcode,
re-tagged coverageBasis="bottom-coverage-pct" (the legacy 2.4
elements/m² was a prior mis-conversion; we can't recover the
original % so it's a single-point curve under key "0").
- jaeger-jetflex-td-65-2-g-epdm-1000.json — extracted from the Jäger
EPDM-1000mm SSOTE/DWP chart on the data sheet (vector-PDF read).
SSOTE 8.20→6.40 %/m, DWP 25→48 mbar across Q 2-12 Nm³/h. Single
coverage (vendor doesn't state test conditions).
- aerostrip-phoenix.json — 4-coverage SOTE family at 4.75 m water
depth (DD 5/10/15/20 %, flux 10-70 Nm³/h·m²) from the Entec/de
Winter 2023-11-22 dataset; DWP curve from the 21 % @ 4.05 m chart.
- pik300.json / prk300.json — 5-coverage SOTE + SSOTR (DD 5-25 %)
with split DWP per model variant, water depth ≈ 4.0 m inferred from
the SOTE↔SSOTR ratio in the source spreadsheet.
src/configs/diffuser.json:
- New asset.{model, assetTagNumber} block so the editor's selected
model id survives validation.
- diffuser.density description corrected to "Bottom coverage [%]";
default 2.4 → 15 (typical fine-bubble install).
src/configs/{rotatingMachine,valve}.json: small alignment edits that
came with the registry phase.
src/menu/asset.js + src/menu/aquonSamples.js: rewritten as facades
over assetResolver, keeping the editor-side cascade behaviour intact.

The P6.4 diffuser refactor reads headerPressure, localAtmPressure,
waterDensity, and zoneVolume out of the config. validateSchema strips
unknown keys, so without these definitions the values fell out of the
config object before specificClass could read them. Added with
sensible defaults that match the pre-refactor inline constants.
