Set block-vav (בלוק ו', רקע/background) generation effort from medium to low in BLOCK_CONFIG. The #208 empirical effort calibration (scripts/calibrate_effort.py, report data/eval/effort-calibration-20260630T155054Z.md, n=7 finals) found that for block-vav, low effort lands closest to chair Dafna Tamir's finalized text — winning on BOTH the composite distance metric (low 0.4454 vs medium 0.4749 vs high 0.5381 vs xhigh 0.5413) AND the cleaner style signal anti_pattern_total (low 1.57 vs medium 2.29 vs high 4.14). Chair (chaim) approved adopting low for block-vav. This is the only block with a clean/confident calibration signal — block-zayin and block-yod-alef signals were ambiguous/tied and are left unchanged. No other block effort is touched. Invariants: G8 (effort empirically calibrated, not by-feel); claude_session-local-only (block_writer runs via the local MCP/claude_local generation path). Host-side generation parameter — after merge the host tree needs `git pull` to take effect. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
