- Key finding: BOTTLENECK COMPOSITIONALITY showing strong initial results

KEY SCIENTIFIC FINDINGS
=======================

1. BOTTLENECK COMPOSITIONALITY — NEW STRONG POSITIVE SIGNAL (Finding #37)
   Now 31 completed seeds. Both sampled results show bottleneck_helps_compositionality=true.
   A narrow bottleneck layer [W→B→W] produces 4-8% absolute reduction in compositional
   gap, substantially stronger than orthogonality regularization (~1-2%). Best configurations:
   w128_b16 (gap ~0.57 vs baseline ~0.94) and w256_b32 (gap ~0.55 vs baseline ~0.60).
   Wider networks WITH bottleneck consistently beat narrower networks WITHOUT it —
   this is the first intervention that reverses the width-compositionality tradeoff
   (Finding #31). Bottleneck rank stays well below width, confirming the architectural
   constraint forces efficient representation use.

2. ORTHOGONALITY COMPOSITIONALITY — ACCUMULATING CONFIRMATION (Finding #36)
   Now 75 completed seeds (up from ~16). ortho_rescues_compositionality=true is
   consistent across seeds. ortho_helps_wide_networks is MIXED (true in some, false
   in others), suggesting the effect is width-dependent. Baseline gaps confirm Finding #31
   (wider = worse). Best ortho gaps show modest 1-2% improvement at each width.
   Effect confirmed but modest compared to bottleneck approach.

3. COMPOSITIONALITY RESEARCH LINE — OVERALL PICTURE
   We now have a clear hierarchy of interventions for compositionality:
   a) Bottleneck architecture: STRONG (4-8% gap reduction, reverses width tradeoff)
   b) Orthogonality regularization: MODERATE (1-2% gap reduction, consistent)
   c) Dropout regularization: WEAK/WIDTH-DEPENDENT (helps narrow, not wide — Finding #35)
   d) Magnitude pruning: INEFFECTIVE (Finding #34)
   Next step: test combined bottleneck + orthogonality.

FLEET STATUS
============
Active hosts: 80+ in last 72h
Over-queued hosts still draining: 113, 137, 159, 219, 222, 319 (from previous sessions)
All other hosts now fully loaded with fresh work.

NEXT SESSION PRIORITIES
=======================
1. Analyze accumulating bottleneck results — this is the most promising finding
2. If bottleneck confirmed with 50+ seeds, design combined bottleneck+orthogonality experiment
3. Continue cross-validating orthocomp (target: 100+ seeds)
4. Consider retiring some standard-line experiments if orthocomp/bottleneck dominate
5. Watch for failures on new deployments (s0303d workunits)
