- medium condition key (print|screen) recorded in raw_results.csv - INSTRUCTIONS.md 2b: photographing the sheets on a display — what the screen arm can answer (camera pipeline, angle, glare, moire) and what only print can (ink gamut/paper survival) - manifest template updated with a screen-arm example
- 24 iPhone photos of 001-s0 on a Studio Display (TrueTone x brightness sweep), identical pipeline, no photo preprocessing: nothing recognised - diagnosis: missing scene localisation dominates (SI-025); band segmentation fragile on real crops; duty biased past synthetic-calibrated tolerance by display bloom; colour shifts warm with no relationship path on band sheets; phase origin-locked as SI-014 predicted - pilot manifest committed; raw photos gitignored (102MB) - next: localisation stage, port two-path colour to band grammars
…ilot re-run - recogniser/locate.py: sheet-ink-conditioned region finder with chroma floor, page-quad rectification, capture-moire low-pass (SI-025 decided) - scene mode in recognise(); bare fragments byte-identical via >=90% short-circuit - two-path colour ported to 2-ink band sheets with overfit guards (SI-027) - exp-003-screen-rerun: same 24 photos, 0/24 -> 4/24 candidates, mean aggregate 10x; ratio within ~1x tolerance when segmentation survives (11/24 frames); duty systematically +0.02..+0.22 from emissive bloom; colour diagonal-plus-bloom confirmed (post-gain dE 11.5) - 10 new tests; 164 total green

Small follow-up to #5: supports photographing the print-pack sheets displayed on a screen when no printer is available.
mediumcondition key (print|screen) to the manifest/CSV so the two arms stay separate in the data.Ingest tests pass (14).
