Prepares session 4 for handoff. No new measurements; this reconciles the docs with what session 4 changed and makes the next session's entry point cheaper. - tools/bench/check.sh re-runs both display regression tests from the Blu-ray in ~40 s and prints ALL GREEN. Verified green cold, after wiping tmp/ and re-extracting. STATUS and README both open with it, because everything downstream assumes the display path is pixel-exact and nothing previously checked that in one command. - Reconciled the figures session 4 invalidated. Session 3's 38.88 dB ceiling is struck through in STATUS with a pointer to 40.81; the "three facts the player must honour" table no longer quotes R20 = 0x0116, which was the 768-wide IPL timing and would have been copied into the player as if it were the shipping value. crtc_mode.lua is now named as the single source of truth for CRTC registers, in both STATUS and README. The 38.88 dB in the session-3 reproduce section is left alone and annotated instead: it is correct for that test, which still packs I = 1. The two numbers disagree for a reason and a reader should be able to see which is which. - Next-step 2 now leads with something smaller than "write the decoder": a dumb full-frame RAM->GVRAM blit in 68000 code, timed. That number alone confirms or kills the 38% estimate, and needs no bitstream, codebooks, or DLX1 parsing. The reference image and its checker already exist. - Parked the user's Cliff Hanger / Lupin III follow-on in STATUS so it is not lost and not mistaken for scheduled work. Cheaper than this project on every axis except media prep, which is where it would actually stall. Claude-Session: https://claude.ai/code/session_01194oWYW8DQXK1SZ2DnChW6
