release notes

Automated release from CI pipeline

Changes: research(R6.2.2): N-anchor multistatic placement saturation — practical knee at N=5 (#720)

Extends R6.2 from single-pair to N-anchor placement search via union of all C(N,2) pairwise Fresnel ellipses. Greedy + K=8 random restarts.

Saturation curve on 5x5 m bedroom (3 target zones: bed + chair + desk, 40 wall-candidates, 434 grid points, 2.4 GHz):

N	Pairs	Coverage	Marginal
2	1	35.7%	+35.7 pp
3	3	63.4%	+27.6 pp
4	6	86.2%	+22.8 pp
5	10	96.8%	+10.6 pp
6	15	100.0%	+3.2 pp
7	21	100.0%	+0.0 pp

Practical knee at N=5. Past this, diminishing returns.

Three regimes:

Single-feature (presence): 2-3 anchors (36-63%)
Multi-feature (pose+vitals+count): 4-5 anchors (86-97%)
Mission-critical (medical): 6 anchors (100%)
Beyond 6: wasted

Cost-optimisation: Cognitum Seed BOM is 9-15 USD. The 4->5 anchor jump buys +10.6 pp coverage; the 5->6 jump buys only +3.2 pp for the same cost. Consumer recommendation: 5 anchors. Commercial / medical: 6.

Convenient numerology: N=5 simultaneously satisfies three other constraints:

R7 multi-link mincut: needs N >= 4 for single-anchor-compromise detection
ADR-105 federation Krum: f=1 byzantine tolerance requires K >= 5
R6.2.2 coverage knee: 5 hits practical saturation

These all bound by similar inverse-square-of-geometry scaling, so the alignment is not coincidental.

ADR-029 (multistatic) didn't specify anchor counts; R6.2.2 fills that gap with a benchmark-backed number.

Honest scope: single 5x5m geometry tested, 2D still (R6.2.1 = 3D not yet built), free-space (multipath adds +5-15% beyond Fresnel), greedy with 8 restarts approximates global optimum to 1-2 pp.

Composes with:

R6/R6.2 (direct generalisation)
R7 (mincut needs N>=4)
R1 (placement x precision = full geometry budget)
ADR-029 (architectural recommendation now has a number)
ADR-105 (Krum bound matches)
R10, R11, R14 (other geometries / use cases)

Coordination: ticks/tick-17.md, no PROGRESS.md edit.
