plans/x265: record PROBE-SPLAT-μ-HYDRATION-RHO leg 1 results (DROP for static μ)

The probe queued at the tail of the plan RAN (lance-graph
crates/helix/examples/mu_hydration_probe.rs). Leg 1 verdict: KILL→DROP for
static spatially-addressed μ-hydration (escalation ≈1.0). The ctrl_naddr
contrast proves the mechanism — hydration is addressing-dependent, motion-only;
μ-hydration ⊂ motion-hydration. Comma fence green (Steinhaus three-gap = 3,
coprime full-perm). Full write-up: lance-graph E-3DGS-MU-HYDRATION-2.

+### Results — leg 1 RAN (2026-07-19, `E-3DGS-MU-HYDRATION-2`)
+
+Leg 1 (the synthetic-structured falsifier, before the real-`.ply` v2) ran on
+lance-graph `crates/helix/examples/mu_hydration_probe.rs` (std-only,
+`helix::placement` public API, SplitMix64, 5 tests green):
+
+```
+set=ctrl_naddr  rho=1.0000 residual=0.0000 escalation=0.0000   ← φ-phase at GENERATION index: perfect
+set=ctrl        rho=-0.0198 escalation=0.9978                   ← SAME cloud, MORTON spatial address: collapses
+set=nonphi      rho=-0.0676 escalation=1.0000                   ← structured cloud, spatial address: no win
+comma_phi_three_gap_distinct=3   comma_coprime_full_perm=1      ← comma fence green (Steinhaus ≤3 + coprime full-perm)
+```
+
+**Verdict: KILL→DROP for STATIC spatially-addressed μ-hydration** — escalation ≈1.0
+is precisely the KILL band; a spatially-addressed static cloud collapses to the
+ordinary float-SoA `splat3d` already ships (no positions-free win). The
+`ctrl_naddr` contrast (same data, `rho=1.0` at the generation index vs `rho≈0` at
+the Morton address) proves hydration is **addressing-dependent, not data-dependent**:
+the win needs a transmitted sequential generation index, which motion has (the
+frame/path counter — the `E-X265-HEADTOHEAD-1` ∞-PSNR case) and a static cloud does
+not. **μ-hydration ⊂ motion-hydration.** The comma is the decoupler: φ's
+incommensurability (three-gap = 3) is exactly what makes the spatial address unable
+to invert to `n`. The real-`.ply` `splat3d::ply` leg (v2) would confirm on trained
+geometry but the mechanism already forecloses the static win.
