16,384 lowest-cost-A days of the 2^24 census), `--sample 65536 --seed 1` (random days in [genesis, genesis + 2^32)).
Logs: logs/adv-mixer-2/scm-calendar.log, scm-tail-2p24.log, scm-sample-2p16.log. The restricted chain form: odd `a`,
`b` already built, `a + (b << s)`, `a - (b << s)`, `(b << s) - a` for `s` in 1..31, or `a x b`; no odd-part
normalisation across shifts, so every level is a subset of what a synthesiser reaches.

| Calendar, 36,525 days | 584,400 | 50 (8.6e-5) | 2,180 (3.7e-3) | 69,987 (12.0 percent) | 87.6 percent |
| Random sample, 65,536 days | 1,048,576 | 79 (7.5e-5) | 3,777 (3.6e-3) | 125,020 (11.9 percent) | 88.1 percent |
| Census tail, 16,384 lowest-A days | 262,144 | 329 (1.3e-3), plus 21 at 2 | 5,970 (2.3 percent) | 69,087 (26.4 percent) | 71.3 percent |
Reading: the tail days are tail days because their constants are cheap, and the certificate reaches twice as many of
their words (28.7 percent at 5 or fewer against 12.3 percent); a synthesiser's real cost per word is at most 5 for
those and unknown for the rest, so the FPGA's true per-day spread is bounded above by model A's and is not measured
here. A longer pass computes the optimal chain length for every odd constant (an exhaustive adder-graph search over
2^31 values, feasible on a box in hours) and replaces models A and B with the exact per-word table.
### Q6 ROT diffusion (PASS, BOUND)
Command on box 2 (queue 05, 21:41 to 21:4x UK, 1 leased core each, 5 s to 60 s per day): `adv-mixer-2 avalanche
--index <day> --states 1024` and `--plant alleq|rot1|weakday`. Logs: logs/adv-mixer-2/avalanche-*.log. Round keys
of round 0 (`round_key_mult(0, j, 8)`); each of the 512 input bits flipped on 1,024 random states; mean flip
fraction over the 512 x 512 input-output pairs, the minimum and maximum per pair, the 22 address bits of s[0], and
the pairs never flipped.

Reading: one application never diffuses fully on any day (the quarter-round structure, not the draw), and the draws
in {1, 2, 30, 31} diffuse least at k = 1 (0.33 against 0.46). By k = 2 every day, the planted ones included, sits at
the uniform 0.500 with every pair flipped, and the 22 address bits with them; 8 applications separate consecutive
cache reads and 72 make an item. No ROT draw lets an attacker predict an address or skip an application, and a
bit-exact verifier would reject the result if one did. Gain from any ROT class: 0 ops on every day.
### Reconciliation with the attack-pass lane's F4 census (read: docs/analysis/attack-pass/f4-weakday.md on branch attack-pass, the one defender file this lane was allowed, 21:4x UK)
Both censuses walk the same 2^24 chain days through `MixParams::with_shape` and both price a per-day FPGA LUT
