c-csi-cross-geometry-scaleout — session 01KX3ES7SMT162PBW6RZTRETB3 (2026-07-09): Phase-2 blocked, 0 runs
Verdict: a cheap re-verification of the Phase-2 prerequisite, which remains unmet — no simulations launched. The powered primary (C1) requires n≈40 distinct floors (n₀ = z²σ²/d², σ≈4.82, d=1.5). gis_stats reports 13 floors / 12 experiments in PostGIS, and gis_experiments confirms only 6 of the 10 Phase-1 replications: floors are staged (12439-multiroom, 1374, 147440, 7421, 16157, 12419); the other four — 10156, 10425, 6090, 8266 — are still absent, and no ≥40-floor Phase-2 import batch (ResPlan converter → gis_rebuild_nrg → gis_validate) has landed. Launching the 150-run sweep would reproduce an identical n=6 pilot with zero information gain over the 2-day-old session, and cannot move C1's powered gate. Sealed as a clean partial.
Prerequisite status
- Prereq #1 (PostGIS reachable on the runner): CLEARED.
gis_statsreturned 2431 rows across 13 floors; the connection-refused that blocked the 2026-07-06 topology sibling (01KWWJ0REM…) is gone. - Prereq #2 (≥40-floor import for Phase 2): STILL OPEN. 13 floors present; 6 of 10 Phase-1 floors staged.
Criteria (carry-over from prior session 01KWYBEJQK4307TTP9KMRY0DEY, 2026-07-07, 90 gate-passed runs)
This session added no corpus; the resolvable criteria stand on that session's persisted artefacts/ (cross_geometry.parquet, per-floor CV(N) table, LOFO breakdown, metrics.json).
- C1 (primary inflation CI) — UNRESOLVED / under-powered, blocked. Pooled ×3.37; floor-cluster 95% CI [1.04, 9.85], lower bound 1.04 < 1.5. A heterogeneous 0.70×–49.8× per-floor mixture; at 6 clusters the interval is unreliable and its exclusion of 1.0 is not leaned on. Requires Phase 2 (≥40 floors).
- C2 (variance split) — RESOLVED (PASS). σ²_floor 0.0109 vs σ²_seed 0.000165 (66×); between-floor SD 0.105 vs between-seed 0.0116 (9×). Geometry dominates seed decisively in the CV(N) signal.
- C3 (comparator honesty) — RESOLVED (PASS). Held-out leave-one-occupancy-out MAE 0.088 vs within-floor 0.026; the in-sample-residual bug is fixed.
Next action for the operator
Stage ≥40 ResPlan floors (start with the 4 missing Phase-1 floors), extend the campaign replications: block, then re-dispatch for the powered Phase 2. Until the floor corpus grows past ~40, C1 cannot be resolved — seed replication is cheap, floor replication is what buys the CI. No figures rendered (no new runs); the prior session's csi_cross_geometry small-multiples + CI panel and seed_trace figures remain the current visual record.
Honest scope
In-silico, ResPlan geometries, single band (2.4 GHz), CSI-only. This session is a budget-disciplined blocker re-confirmation, not a science pass.
