The measurement programme
The case rests on ten measurements, not one. None of the ten has been systematically run on the surviving artefacts.
The integrated craft reading predicts measurable behaviour on at least seven channels: electrical, acoustic, piezoelectric, ionising, atmospheric, harmonic, and symbolic. Each channel suggests a specific instrument and a specific protocol. The ten experiments below cover those channels in tractable form, with predicted outcomes specified in advance. Some are field measurements on intact buildings, some are archival searches, one is a controlled human study. All ten are buildable with off the shelf instrumentation and a modest budget. The current state of all ten is the same: designed, fundable, unrun.
Why ten and not one
The dual purpose reading is multi channel by design. The measurement programme has to be too.
A surviving 19th century rooftop is a coupled passive system on seven channels, per Section 51 of the project knowledgebase. The site documents the electrical channel in detail and treats the others as adjacent. A defensible programme of research has to test each channel directly, not just the most obvious one. The RF audit on a single spire (designed in full at measurement.html) is the flagship experiment because it most directly tests the antenna claim, but the other nine experiments below are equally tractable, equally publishable, and address claims the RF audit cannot reach.
Each card below names one experiment, the instrument or archive it requires, the budget bracket, and the predicted outcome that would either confirm or refute the corresponding sub claim. The shared frame: each result is publishable as primary data either way. Negative findings are not failures; they are the cleanest refutation surface the project has. Specifying the outcomes before running the experiments is what separates a research programme from a confirmation hunt.
Ten experiments, none of them yet run, each one tractable inside a single PhD or a single departmental fieldwork visit. The combined budget is below half a million dollars. The combined publication footprint is roughly four to six peer reviewed papers across electromagnetics, atmospheric physics, archaeoacoustics, and conservation science.
The list, with predicted outcomes
Ten measurements, one card each, ready to adopt
The first experiment is fully designed at measurement.html. The remaining nine are sized for departmental fieldwork or an undergraduate thesis project. Predicted outcomes and proposed budgets are conservative.

small ion counter
Predicts
2,000 to 10,000 per cm3
Status, proposed, instrument off the shelf
-
EXPERIMENT 03
Ozone concentration in the local air of buildings with active corona
Handheld ozone monitor at two metres from spire tips in humid weather and at storm onset. Tests whether the corona discharge predicted by the geometry produces detectable ozone above urban background.
Instrument
handheld O3 monitor

opportunistic, weeks
Predicts
5 to 15 ppb excess
Status, proposed
-
EXPERIMENT 04
Lightning strike statistics across a century of ornament condition
Archival survey of insurance and parish records correlating documented strike incidents against rooftop ornamental integrity.

Method
archival, insurance and parish
Duration
three to six months
Predicts
reduced strike incidence
Status, proposed, no instrument required
-
EXPERIMENT 05
Electrical continuity survey of 19th century ridge ironwork
Four wire low resistance ohmmeter test across the iron ridge crest of fifteen to twenty preserved historic buildings. Tests the distributed perimeter collector hypothesis at the population level. Documents how many ridges are continuous, how many are grounded, and how many are electrically floating.
Instrument
four wire low ohm meter
Predicts
majority continuous
Status, citizen distributable
-
EXPERIMENT 06
Low noise electrometer across an exposed granite block on a historic building foundation in a region with granite construction tradition. Logged across wind events. Tests whether the quartz content of granitic stone produces measurable continuous low voltage signatures under typical structural loading. See the granite page for the full physics derivation and protocol.
Instrument
low noise voltmeter

EXPERIMENT 07
Infrasound mapping in cities with active versus silenced bell towers
Class one sound level meter with infrasonic capability deployed at fixed radial points in three matched city pairs. One city in each pair retains its pre 1914 bell ringing tradition. The other lost its bells to wartime requisition and never replaced them. Tests whether the low frequency acoustic environment of a pre modern town centre is measurably different.
Instrument

EXPERIMENT 09
Greenhouse scale replication of the elevated charged wire crop stimulation protocol from Karl Selim Lemstrom's 1904 monograph, run against modern statistical methodology. Tests the residual reproducible effect that the 2021 ResearchGate review identified as present but methodologically thin in the existing literature. See the electroculture page for the 1746 to 1968 research line and the full protocol.

EXPERIMENT 10
Foundry catalogue plate identification of the 124 image corpus
Plate by plate visual matching of corpus images against the digitised catalogues of Fiske 1881 and 1893, Bonfils and Fesquet 1904, Limbourg 1910, Mott 1882 and 1887, plus the European foundries surveyed in the project. The output is a per image probable plate citation column added to the corpus data. Closes the open question of where each ornament came from.

Duration
six to eight weeks
Predicts
strong match on 30 to 60 percent
Status, proposed, tooling and curation
What the ten together would establish
Four positives convert the verdict box. Four nulls retire one channel each.
The dual purpose case currently stands on geometry, foundry catalogue evidence, statistical orthogonality between Christian and engineering features in the corpus, and the documented destruction of the surviving sample. None of those is a primary measurement on a surviving artefact. The ten experiments listed above are the missing layer. Even four positive results across the ten would move the verdict box from "empirically live" to "empirically confirmed on these specific buildings." Even four negative results would retire one channel each, sharpening the remaining claims by removing the ones the data did not support.
The programme also reframes the project's central blocker. The repository currently has one cold email drafted. With a ten experiment programme on a single index page, the recruitment problem becomes "pick whichever of these matches your laboratory" rather than "fund the only one we have specified." That widens the recruitment funnel from electromagnetics laboratories to archaeoacoustic groups, conservation programmes, atmospheric chemistry departments, environmental psychology labs, agricultural extension services, and undergraduate thesis committees in any of those fields.
Adoption of any one experiment by any one partner moves the project forward. The full programme would be the work of a decade and a small consortium. The first measurement is the work of one fieldwork visit. The research partnership brief exists to make that first visit easier to organise than to defer.
The forward looking complement to the ten experiments is the rebuild specification: what a 21st century custom home that carries the integrated craft would actually cost, broken into five line items with explicit upper and lower bounds. The ten experiments are the project's backward looking measurement programme. The rebuild is the project's present tense constructive statement.
