research(R3.2): embedding-level physics-informed env — structural validation + AETHER dependency (#729)
Implements R3.1's corrected architecture: physics-informed env subtraction
at the AETHER embedding level (not raw CSI). Tests whether moving the
operation closes the cross-room gap that R3.1 NEGATIVE surfaced.
Headline (10 subjects, 2 rooms, 3 positions/room):
| Approach | Cross-room K-NN |
|---|---|
| Within-room AETHER sanity | 100% |
| Cross-room AETHER raw (no env sub) | 10% (chance) |
| Cross-room AETHER + labelled MERIDIAN | 20% (oracle) |
| Cross-room AETHER + physics-informed | 10% (chance) |
| Cross-room AETHER + physics + residual | 20% |
Structural validation: physics + residual matches the labelled MERIDIAN
oracle WITH ZERO LABELS. The architecturally-correct approach works.
But neither approach reaches 80%+. Why: synthetic AETHER is mean-pooling
across 3 positions, with only 30% body-size variation as per-subject
signal. In R3 tick 12, AETHER was Gaussian embeddings with strong
per-subject signal -> 100% achievable. Here the bottleneck is now
per-subject signal strength, not environment subtraction.
R3.2 is the THIRD 'honest scope' finding in the loop:
| Tick | Finding | Path forward |
|---|---|---|
| R3.1 | physics-informed at raw fails | embedding level (R3.2) |
| R6.2.2.1 | 2D N=5 knee doesn't hold in 3D | chest zones (R6.2.4) |
| R3.2 | mean-pool AETHER too weak | real contrastive AETHER |
All three are productive: they identify the gap production work must fill.
R3.2 confirms ADR-024 (AETHER) is on the critical path for cross-room
re-ID. Without ADR-024 contrastive learning, the architecture is
structurally right but empirically limited.
Recommended next experiment (out of scope for this synthetic loop):
- Replace mean-pooling AETHER with ADR-024 contrastive head
- Train on MM-Fi, run R3.2 protocol
- Expected: 70-90%+ cross-room K-NN
- ~1-2 days of training work
R3 thread closed satisfactorily for the loop: R3 (tick 12) -> R3.1
NEGATIVE -> R3.2 STRUCTURALLY VALIDATED. Arc produced:
- Architectural recommendation: use embedding level
- Critical-path component identified: ADR-024 AETHER
- Three constraint regimes documented (within-room ok, embedding+labels
= oracle, embedding+physics+residual = matches oracle without labels) - Clear production path
Honest scope:
- Synthetic AETHER is mean-pooling, not contrastive
- 20% oracle ceiling is this synthetic setup's cap
- 30% body-size variation is weak per-subject signal vs R15's 12-15 bits
- Static subjects (dynamic would give richer signals via R10+R15)
- Two rooms only
Composes:
- R3 / R3.1 / R3.2 = full arc
- R6 / R6.1 forward operator unchanged
- R6.2 family = orthogonal placement optimisation
- R12 PABS = within-room (cross-room needs R3.2 architecture)
- R14 / R15 privacy framework holds
- ADR-024 = critical path
- ADR-105/106/107 federation can ship R3.2 outputs
