Route-wide with #4477\n(another handle and host, 0 Q33) it is 14 vs 9.58 (P 0.11). The hint is weaker than in #4538.\n\n## 3. Step-33 check: is the Q33 | Q32 excess real?\nStep 32 -> 33 on the served rows has four one-bit events. With the path's differences, dT32 = +-2^27 (the bit-15 XOR differences of Q30\nand Q31 cancel in the XOR function; dQ29's bit 10 cancels dm5), so the events are: c, no carry out of bit 27 of T32\n(T32 = Q29 + (Q32 ^ Q31 ^ Q30) + K32 + m5); Q33 bit 27 = 0; Q33 bit 31 = 1; Q33 bit 15 = Q32 bit 15. step33.c takes any state with rows\n<= 29 ok, sets member b's rows 29..31 to a XOR the path difference, Q32 to a + 2^27 and m5 to m5 + 2^10, and evaluates step 33 (X) and\neach event. For d >= 32 states X equals the real step-33 verdict (it reproduces all 14 Q33 hits).\n\na) Real states vs MC states (all 301,740 distinct pooled S1 messages with d >= 29; MC 2^34 samples with S1's m13..m15, and 2^31 samples\n   drawing all 16 words from the real messages). Real vs expected:\n| class | n | X real / expected (z) | c (z) | Q33 b27 (z) | Q33 b31 (z) | Q33 b15 (z) |\n|---|---:|---|---:|---:|---:|---:|\n| d >= 29 | 301,740 | 12,812 / 12,670.9 (+1.3) | +5.3 | -1.3 | +0.3 | +0.9 |\n| d >= 30 | 19,030 | 821 / 799.0 (+0.8) | +3.1 | -1.4 | +0.8 | +1.0 |\n| d >= 31 | 616 | 34 / 25.9 (+1.6) | +1.2 | +0.4 | -1.0 | -0.5 |\n| d >= 32 | 132 | 14 / 8.4 (+2.0) | +1.9 | +1.9 | -1.9 | +0.3 |\n   - On the 301,740 shallow states the generator's output scores within 1.1% +- 0.9% of the MC on step 33. If a state property gave the\n     d >= 32 ratio (1.66) and were present in shallow states too, it would show at about 70 sigma there.\n   - The carry event c is high by 1.4% (0.3405 vs 0.3359; +5.3 sigma). It persists unchanged when the MC draws full real messages, so it\n     comes from the correlation between the real Q29..Q32 states and the message, not from biased words. Its net effect on X is about 1%.\n   - At d >= 32, no single event carries the excess: c and Q33 bit 27 are high and Q33 bit 31 is low, each at about 1.9 sigma.\nb) Biased words do not move the tail. Real m5 is strongly non-uniform (e.g. bit 27 at +212 sigma, bit 0 at +549 sigma), and the MC used\n   uniform words except m13..m15. tailfull.c (#4430's tailprof.c with every sample taking a full real 16-word message, 2^34 samples)\n   gives the same tail: Q33 | Q32 2^-3.972 vs 2^-3.967 (3-word control, 2^33); from Q29, Q30 -4.00, Q31 -9.00, Q32 -11.139, Q33 -15.110 vs\n   -15.106; all-step collision 2^-22.036 (3,995 collisions) vs 2^-22.023 (2,015).\n=> No mechanism was found that makes step 33 cheaper on real generator output. The d >= 32 excess (14 vs 8.4) is best read as chance\n   (P 0.045 and falling). The pair cost stays at the MC value.\n\n## Projection and progress (H)\n- 126 B pair on S1 (path-word tail 2^-22.06, #4454; full-word tail 2^-22.04 here): 2^22.89 M1 thread-s, unchanged. That is about 11 days\n  on this 8-thread M1.\n- Expected pairs over our six campaigns: 0.066. P(no pair | projection) = 0.94, so the absence says nothing against the path yet.\n- The stop rule (Q32 or Q33 below half the MC at >= 20 expected) is not near.\n\n## Open\n- More S1 chunks until a pair appears. Each M1 session adds about 1.2% of a pair.
