Wave-tuned hulls
Status is derived only from the shepherd-authored triage/prediction data above -- community submissions and claims are a separate overlay and can never change it (see the participation panel below).
Claim (verbatim)
Wave-tuned hulls. This joins naval architecture to physical oceanography. A ship whose length sits near the dominant wavelength of local seas pitches resonantly — an exhausting, dangerous motion — so builders who iterate on what survives should end up with hull lengths that avoid the resonant band of their home waters. Different seas have different wave spectra: the Baltic's short fetch makes short, steep waves, while the open Atlantic carries long swells. If regional shipbuilding traditions were tuned by their seas, then regional ship lengths should avoid resonant pitching in local wave spectra, and the length distributions of Baltic and Atlantic wrecks should differ not arbitrarily but exactly as wave climatology predicts — each tradition's lengths skirting its own sea's resonant band. The seas, on this view, acted as selection environments, and the wreck record preserves their signature in metres of keel.
Prediction clause (verbatim)
For each vessel in wreck dimension databases for the Baltic and Atlantic seaboards, record hull length and date, and compute regional wave spectra from climatological data to identify the resonant pitching band for each sea; compare wreck length distributions to those bands. Primary clause: each region's length distribution must show a significant deficit — at least 30 percent below the smoothed neighbouring density — within its own sea's resonant band, and the Baltic–Atlantic difference between distributions must lie in the direction wave climatology predicts; statistically identical distributions across the two seas, or lengths concentrated inside the resonant bands, falsify the claim. The verdict follows the primary clause.
Kill-dataset (verbatim)
wreck dimension databases.
Nobody has run this test. The kill-data is named above. If you can run it — or you know the paper that already settles it — claim the kill or submit the prior scholarship. Kills and prior scholarship are credited here, by name, as they come in.

Provenance
Run: Imported conversation (verbatim harvest) · model: claude-fable-5
Origin: operator conversation with Claude Fable 5 at max effort, conducted 2026-07-03, relayed verbatim by the operator into the shepherd session on 2026-07-04. No ModelRun exists for the original generation (it happened outside the pipeline); this transcript file is the canonical capture. Transcript path: docs/generated/conjecture_harvest_fablemax_20260703.md. Model (operator-attested, not pipeline-recorded): claude-fable-5. Novelty disclaimer (verbatim, load-bearing -- rule 4): "Same caveat as before, doubled: at 100 items across all of archaeology and history, some of these will have cousins in the literature I can't check. What I can guarantee is the format — each links two things not normally linked, and each names the dataset or measurement that would kill it."
Novelty / leakage triage
no prior formulation located (search dated 2026-07-05)
The naval-architecture principle (pitching depends on hull-length-to-wavelength ratio), regional wave climatologies (Baltic, North Atlantic), and wreck-dimension databases all exist as separate resources, but no source was located cross-referencing historical wreck-length distributions against regional wave spectra to test resonance avoidance. No prior formulation located (search dated 2026-07-05).
