 VERDICT (21:1x BST, to the coordinator and the hash lane; the mirror's sha of this landing is read back before any line says so): PASS on the acceptance's side on the frozen object's draw and acceptance (ac86d7910 = b24dfc162's, the packs' draw read back equal on both ids), under the full rule AND under the crate's own predicate, which now agree: 0 exhausted in 6,000 eras, the floors at 0 to 0.5 percent of reaching candidates, no hot set and nothing over 1.2x on the mirror-valid subset at 2^20, the bit-R class at its 6.11 level (the fold's half). The two things that stand outside this row: the live-dataset census on the fold and the 64-register window on the exact object is the kernel path's (Review B's F06, the census hand's instrument on the rented cards), and a later V6-02 commit on class-v6 (0266c9ec0, the executed load count routed into the acceptance) moved the reg64 verdicts and the re-exported id (0x1626c5853aa84261 at 43f1b1581 against the object's 0x4de7b836cc40a4ea), which the hash lane reported and is reverting; this section's rows are on ac86d7910, before it, and bind only that tree.
 
+### 6.13 The chain-seed draw through the acceptance (class-v6 1a938abe4, the generator the chain runs; the coordinator's order of 21:3x BST; build-6, 21:49 to 21:54 BST)
+
+The object: the one program the chain draws at genesis from the generator at 1a938abe4 (the final class-v6 tree, both of this lane's predicate findings in), class `mx8+sh256x27+state+reg64c+fold+rw`, epoch seed af89be5d..., day 20730. Two era inputs were in circulation at 21:4x BST and both are read back here, labelled; the engine's own era input is the one that binds, and the verdict line names it. The harness: the family harness ported onto 1a938abe4 (`logs/harness-v6-1a938abe4.diff`, 513 lines, the same port as 6.12's with the era taken from `IGNEUM_FG_EPOCH_HEX` and `IGNEUM_FG_ERA_HEX` when set, so the row is the chain's program and not a drawn one), one era per row, the full rule and the crate's own predicate (`IGNEUM_FG_CHAIN_PREDICATE=1`) at width 4 (the pinned genesis width) and at width 1; attack-f8 given a program-0 hex mode (`logs/attack-f8-program0-1a938abe4.diff`, 25 lines: `--programs 0..0` takes the same two hex inputs) on the mirror-valid subset `mx8+sh256x27+rw` at 2^20 nonces. The binary of every census row is a3c1da3b (the `bin/v6-1a938abe4...` test binary; `bin/v6-fin` is the same file by sha256).
+
+The pairing, read back (the igneum-pow CLI built from the 1a938abe4 tree on build-6, `show` with the state file node1-state.igsd1, sha256 abb58003): input A, era `0:af89be5d...` (the pack hl-v6-all-chainseed's `program.json`: era_seed_bytes af89be5d..., id 0x442a1691b3e3507f) draws generator 6, era label 93a14ac6, attempt 0, program id 442a1691b3e3507f, equal to the pack; input B, era `0:edc4fa84...` (the genesis form the hash lane's 21:4x message carries) draws generator 6, era label d810f22d, attempt 0, program id 2a1d6caab4c24564, equal to the hash lane's read. The ids differ because the era input differs, not the tree: one CLI, one epoch, one state file.
+
+| Row | Input A, era 0:af89be5d (id 442a1691b3e3507f) | Input B, era 0:edc4fa84 (id 2a1d6caab4c24564) |

+| The crate's own predicate, width 4 | identical row (`logs/chainseed-w4-chainpred-*`): the two predicates agree on the chain's program as they did on 6.12's 1,500 | identical row (`logs/chainseed-gen-w4-chainpred-*`) |
+| The full rule and the crate's predicate, width 1 | attempt 0, 1 candidate, every part 0; minimum ratio 0.99993 at site 3; bucket 2.250, +5.00 sigma at site 0; both predicates identical; `logs/chainseed-w1-*` | attempt 0, 1 candidate, every part 0; minimum ratio 0.99991 at site 6; bucket 2.375, +5.50 sigma at site 7; both predicates identical; `logs/chainseed-gen-w1-*` |
+| The per-site index-bit read (the bit-R class of 6.2 and 6.12: 21.4 percent of width-4 eras over 6 sigma at one site, 74 percent of those at bit R) | width 4: bit 12 = R at site 2, window 1, z = minus 18.33: the chain's program at this era IS in the bit-R class, in the 6-to-100 sigma band (not the minus 512 mechanism of 6.2; the fold is on); width 1: bit 18, z = minus 3.40, clean | width 4: bit 4 at site 1, z = +3.82, clean of the class; width 1: bit 20, z = minus 3.39, clean |
+| attack-f8, program 0 at 2^20 nonces, the mirror-valid subset `mx8+sh256x27+rw` (the fold, reg64c and state are the kernel path's, as in 6.12) | 6-sigma windowed clear, hot set clear, hottest item 34 reads of 2^20 (0.0000 percent), verdict PASS; lines per hash 1014 to 1024 of 1024 (925,106 nonces at 1024), items per hash 127 or 128 (494 at 127); `logs/f8-chainseed.log`, `logs/f8-chainseed-distinct.txt`, `logs/f8-chainseed-positions.txt` | 6-sigma windowed clear, hot set clear, verdict PASS; lines per hash 1014 to 1024 (925,441 at 1024), items per hash 127 or 128 (590 at 127); `logs/f8-chainseed-gen.log`, `logs/f8-chainseed-gen-distinct.txt`, `logs/f8-chainseed-gen-positions.txt` |
+
+VERDICT (21:5x BST, to the node lane, the steward and the coordinator; the mirror's sha of this landing is read back before any line says so): PASS on the acceptance's side for the chain's program at 1a938abe4 under BOTH era inputs, under the full rule and under the crate's own predicate (which agree row for row): accepted at attempt 0 at both widths, every acceptance part 0, the (c''') ratio 0.9999 against the 0.995 floor, no bucket at the +8 line, no hot set and nothing over the 6-sigma window on the mirror-valid subset at 2^20. The one reading that differs between the inputs and is NOT an acceptance part: at width 4 the input-A program (era 0:af89be5d) sits in the bit-R class (bit 12 at site 2, 18 sigma), which 6.12 measured in 21 percent of width-4 eras on this tree and which the rule does not test; the input-B program (era 0:edc4fa84) is clean of it. If the engine's era input is A, the genesis program carries that known class at the measured level and the lane's standing line on it holds (the fold halves the class and leaves half; a per-era test on the index bits is the ring-B item the rule does not yet have); if B, it does not. The node lane's read of the live node's program-id line decides which column is the chain's.
