Render::deg_mul is auto-tuned by frame load and SWUNG between oracle captures: doorway-still ran right after the heavy terrace-edge capture with the multiplier depressed (mul <= 0 puts thresholds at/below ideal, so 001e/0026/002f select the portless level 1 - retail's zero look-in floods, reproduced exactly at mul = 0), while every other fixture pins ~ +0.99 (thresholds at max). The recon session's "-0.99" live dump was real - taken under the same cdb load. RetailFrameWalk now exposes the multiplier; the doorway test pins 0, the rest use the default. foundry-entry: frames 1-66 reproduce exactly; the F67-F79 standing segment diverges ONLY in building 0036's intra-building DC order (retail 116,118,11d vs replay 11d,116,118). The BSP-traversal microscope pins the flip to 0036's ROOT plane (N=(0,0,-1) D=2.8): replay eye z 2.33 (d=+0.47, NEG-first) vs retail behaving as d<0 (POS-first) - a structural ~0.5 m frame question (positionPush(2)/part-scale), only adjudicable live. Turnkey probe: tools/walk-oracle/fw1-f67-viewpoint-probe.cdb. Fixture status: nine of ten fully conformant; foundry-entry exact through F66 with the 13-frame order segment parked on the probe. Suites: Walk 127/1 skip; hermetic 6,687/0. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
