PR #744 moved the files into 9 thematic folders via git mv but missed the READMEs due to a working-directory issue with git add. This PR adds the actual READMEs: - examples/research-sota/README.md (main overview) - examples/research-sota/01-physics-floor/README.md - examples/research-sota/02-placement/README.md - examples/research-sota/03-spatial-intelligence/README.md - examples/research-sota/04-rssi/README.md - examples/research-sota/05-cross-room-reid/README.md - examples/research-sota/06-structure-detection/README.md - examples/research-sota/07-negative-results/README.md - examples/research-sota/08-verticals/README.md - examples/research-sota/09-quantum-fusion/README.md Each sub-README documents: - Scripts + headlines table - Why this folder bounds/composes with others - Sample output / honest scope - Cross-references to related loop notes + ADRs Main README covers: - Folder map with thread numbers - Cross-folder dependency graph - 8-entry headline findings table - Reading order for newcomers (4 scripts in suggested order) - Honest scope (synthetic-physics caveats) |

08 — Exotic vertical physics
Concrete physics for two vertical applications: wildlife (through-foliage) and maritime (through-bulkhead). Other verticals (R14 empathic, R16 healthcare, R17 industrial, R18 disaster, R19 livestock, R20 quantum) are vision/spec only — only R10 and R11 have computable physics demos.
Scripts
| Script | Thread | Vertical | Headline |
|---|---|---|---|
r10_foliage_attenuation.py |
R10 | Wildlife sensing through foliage | ITU-R P.833-9 attenuation. ESP32 sparse-foliage range: ~100 m at 2.4 GHz (later corrected to ~70 m by R6's Fresnel-clearance consideration). Per-species gait taxonomy (8 species). |
r11_maritime_propagation.py |
R11 | Maritime / ship-cabin sensing | Steel skin depth 3.25 µm at 2.4 GHz → through-bulkhead impossible. But slot diffraction works: cabin door with 2 mm gasket gap = +31 dB SNR margin. Through-seam, not through-bulkhead. |
What R10 (wildlife) enables
- Solar-powered ESP32 nodes at forest edges
- Through-foliage detection at ~70-100 m range
- Per-species gait classification:
| Species | Stride frequency |
|---|---|
| Bear / sloth / wild boar | 0.5-1.5 Hz |
| Human walking | 1.2-2.5 Hz |
| Deer / fox | 1.8-4.5 Hz |
| Squirrel / mouse / songbird | 4.0-15.0 Hz |
The gait taxonomy directly extends to R19 livestock (cattle 0.6-1.2 Hz, pig 1.0-2.0 Hz, etc.).
What R11 (maritime) enables
- Man-overboard surface detection at ~200 m
- Through-seam crew vitals (lone-watch monitoring)
- Container tamper detection via 30 mm vent slots
- Hatch-seal integrity audit (predictive maintenance)
What R11 rules out:
- Through-hull submarine sensing (steel impassable)
- Underwater sensing at WiFi bands (saltwater 853 dB/m)
Composition with privacy + federation chain
Both R10 and R11 use:
cog-wildlifeorcog-maritime-watchpackaging (ADR-100)- Cross-installation federation (ADR-107 + ADR-108 PQC)
- Per-installation embedding spaces (R3 + R14 privacy framework)
For wildlife the privacy framework is largely moot (animals don't consent); for maritime the crew-consent framework applies.
