rUv be5eae2007 quantum-sensing(doc 17): honest classical-quantum fusion — bridges SOTA loop with quantum series 11-16 (#741)
Bridges the existing 6-doc quantum-sensing research series
(docs 11-16, 2026-03-08 onwards) with this loop's 37+ ticks
(2026-05-22). Inherits doc 16's sober reality-check posture
('no 40-mile cardiac magnetometry').

User signal: opened docs/research/quantum-sensing/11-quantum-level-
sensors.md twice in consecutive ticks. Strong repeat signal toward
quantum integration. Doc 17 explicitly bridges the two work streams.

Two reality-checks compose:
1. R13 NEGATIVE (loop tick 11): ruled out classical CSI BP/HRV-contour
   due to 5 dB shortfall (sensor-bound, not physics-bound-period)
2. Doc 16 Ghost Murmur (2026-04-26): ruled out 40-mile NV cardiac
   magnetometry due to cube-of-distance physics

Combined: HONEST FUSION adds NV-diamond cardiac magnetometry at 1-2 m
BEDSIDE RANGES (where cube law gives ~1 pT/sqrt(Hz) SNR), NOT 40 miles.
Classical primitives carry geometry; quantum carries fidelity.

Five-cog fusion roadmap:
- cog-quantum-vitals (NV+CSI, 5y): nvsim + R14 V1 + R15
- cog-rydberg-anchor (calibrated multistatic, 7-10y): R1 + R6.2.2 + Rydberg
- cog-mm-position (atomic clock, 10y): R1 + R3.2 + atomic clock
- cog-deep-rubble-survivor (NV drone, 15y): R18 + NV via drone
- cog-ICU-meg (room-temp SQUID, 20y): R14 V3 + SQUID array

All five stay sober — no Ghost Murmur 40-mile claims.

Cross-reference index: every loop output mapped to quantum-series doc.
- R13 NEGATIVE -> doc 13 NV neural magnetometry recovers HRV
- R14 V3 -> doc 13 + doc 11.2.2 SQUID for MEG
- R6.1 4.7 dB penalty -> doc 11.3.3 quantum illumination (+6 dB)
- R1 CRLB -> doc 11.4 Rydberg+atomic clock (~10 cm)
- R18 disaster -> doc 13 NV cardiac at 5+ m rubble depth

nvsim (ADR-089) integration concretised:
nvsim_output -> R14 V1 fusion / R12 PABS / R7 mincut / R6.1 residual
                                                       ↓
                                                cog-quantum-vitals
~150 LOC glue. Makes nvsim ACTUALLY USEFUL beyond simulator scope.

What this DOES enable:
- Clear integration between 6-doc series and SOTA loop
- Five honest-scope fusion-cog roadmap items
- 'What we are NOT building' list (no 40-mile, no through-multi-walls)
- Bridge for journalists/researchers/contributors

What this DOES NOT enable:
- 40-mile cardiac magnetometry (doc 16 stands)
- Through-multiple-walls quantum (1/r^3 falloff persists)
- Replacement of medical devices without FDA/CE
- Quantum-enhanced WiFi protocol changes (Layer 1 stays classical)

Doc 17 special status:
- First doc to bridge SOTA loop with quantum-sensing series
- Adopts doc 16's sober reality-check posture
- Identifies R13 NEGATIVE as conditionally recoverable (sensor-bound)
- Concretises nvsim → cog integration path

Composes with every loop output (R1, R3, R5-R15, R12.1, R13 NEG
recovered, R14, R15, R16-R20 verticals, ADR-105-109, ADR-113) + all
6 quantum-sensing docs (11-16).

Coordination: ticks/tick-38.md, no PROGRESS.md edit.

User-prompted by repeat opening of doc 11; doc 17 closes the loop
between the two research series.

Tick 38 — 2026-05-22 11:20 UTC

Thread: Quantum-sensing series doc 17 (honest classical-quantum fusion) Verdict: Bridges the existing 6-doc quantum-sensing series (docs 11-16) with this loop's 37+ ticks. Inherits doc 16's sober "no 40-mile cardiac magnetometry" posture.

What shipped

  • docs/research/quantum-sensing/17-honest-classical-quantum-fusion.md — synthesis document in the quantum-sensing series.

Why this tick (user signal)

User opened docs/research/quantum-sensing/11-quantum-level-sensors.md twice in consecutive ticks. Strong repeat signal toward quantum integration. Inspecting the folder revealed a 6-doc series (11-16) that R20 (tick 37) didn't yet acknowledge. Doc 17 explicitly bridges the two work streams.

The two reality-checks composing

  1. R13 NEGATIVE (loop tick 11): ruled out classical CSI BP/HRV-contour due to 5 dB shortfall
  2. Doc 16 Ghost Murmur (2026-04-26): ruled out 40-mile NV cardiac magnetometry due to cube-of-distance physics

Combined: honest fusion adds NV-diamond cardiac magnetometry at 1-2 m bedside ranges (where cube law gives ~1 pT/√Hz SNR), NOT 40 miles. The loop's classical primitives carry geometry; quantum carries fidelity.

Five-cog fusion roadmap

Cog Series-anchor doc Loop primitives Timeline
cog-quantum-vitals (NV + CSI) docs 13/14/15 (nvsim) R14 V1 + R15 + NV HRV contour 5y
cog-rydberg-anchor (calibrated multistatic) doc 11.4 R1 + R6.2.2 + Rydberg 7-10y
cog-mm-position (atomic clock) doc 11 R1 + R3.2 + atomic clock 10y
cog-deep-rubble-survivor (NV drone) docs 13, 16 R18 + NV-via-drone 15y
cog-ICU-meg (room-temp SQUID) doc 11.2.2 R14 V3 + SQUID array 20y

Cross-reference index

Every loop output mapped to a quantum-series doc:

  • R13 NEGATIVE → doc 13 recovers HRV via NV
  • R14 V3 → doc 13 + doc 11.2.2 SQUID for MEG
  • R6.1 4.7 dB penalty → doc 11.3.3 quantum illumination (+6 dB)
  • R1 CRLB → doc 11.4 Rydberg+atomic clock (~10 cm)
  • R18 disaster → doc 13 NV cardiac at 5+ m rubble depth

Lets a reader navigate: "I'm interested in X loop finding; here's the quantum context that extends it."

nvsim (ADR-089) integration concretised

Doc 17 specifies the code path from nvsim (currently a standalone leaf crate, WASM-ready) into production via the loop's primitives:

nvsim_output -> R14 V1 fusion / R12 PABS / R7 mincut / R6.1 residual basis
                                                       ↓
                                                cog-quantum-vitals

~150 LOC of glue. This makes nvsim actually useful beyond simulator scope.

What this DOES enable

  1. Clear integration between existing 6-doc series and SOTA loop
  2. Five honest-scope fusion-cog roadmap items
  3. "What we are NOT building" list (no 40-mile cardiac, no through-walls quantum)
  4. Bridge for journalists / researchers / contributors

What this DOES NOT enable

  • 40-mile cardiac magnetometry (doc 16 stands)
  • Through-multiple-walls quantum (1/r³ falloff persists)
  • Replacement of medical devices without FDA/CE approval
  • Quantum-enhanced WiFi protocol changes (Layer 1 stays classical)

Composes with every loop output

R1, R3, R5-R15, R12.1, R13 NEGATIVE (recovered via NV), R14 V1/V3, R15, R16-R20 verticals, ADR-105-109, ADR-113. Plus all 6 quantum-sensing docs (11-16).

Doc 17 special status

  • First doc to bridge the SOTA loop (2026-05-22) with the quantum-sensing series (2026-03-08 onwards)
  • Adopts doc 16's sober reality-check posture
  • Identifies which loop NEGATIVE results are conditionally recoverable via quantum (R13)
  • Concretises the nvsim → cog integration path
