Spec 2.3: rule 1 measures every chain step on a sanitised clock stored per header
(c(b) = max(c(p) + clamp(t(b) - c(p), -20 T, +20 T), t(b) - 60 T), step min(c(b) - c(p),
20 T)); rule 4 bounds the output to [2^128, MAX_DIFFICULTY_TARGET]; the timestamp rules
are Igneum's own, 10 s ahead of the clock and 10 s behind the selected parent beside the
unchanged past-median rule; new parameter rows, the bounds paragraph rewritten (the old
"next honest block cancels it" was the attack), the attack and test-network results added.
sim/difficulty/sim.py: class Igneum carries the same clock, lag bound and floor, so the
rule as simulated is the rule as coded (attacks.py's igneum-san is now identical to it).
docs/analysis/difficulty-2026-10-03.md section 11: the attack, the three parts, before and
after tables (simulator seeds 7 to 9, base-profile regression within 10% on the 3-seed
means, pool hopping unchanged, the two 15-minute 3-node forger runs), unit tests, limits.
docs/bench-log.md: the 4 October entry. docs/fud-ledger.md: M23, status Fixed.
Node side: vendor/igneum-node branch difficulty, commit 52eacad9.

The four public sentences (F18, P13, E11, L7 in site/litepaper.html and site/index.html) were swept into the concurrent commit cd604db; this commit carries the rest.
Spec 02: finality depth (43,200 DAA s, 12 h of median time) named as the reorg bound, merge depth as a merge limit only, simnet reorg test for gate 2; emission follows the code (365.25-day year, 63,115,200-s halving, 31.688 IGN per DAA second, reds inside the DAA window paid to the merger, E paid per block so coins are blocks times E).
Spec 03: W2 and Q1 denominated in past-median time, weight as a share of each 60-s bucket; W6 keys are free, weight is the only Sybil-resistant quantity; 3.8 and 3.9 point exchanges at the finality depth.
Spec 06: O-3.14, the finality simulation with the DAA in the loop under a pulsed rental (gate 3).
Spec 07: shard sortition draws by weight (blue blocks drawn uniformly from the window); proof-record validity is relative to the carrying block's own selected-parent chain; 1-key-versus-1,000-keys test.
Spec 08: release-key chain, rotation signed by the current key, revocation signed by the previous key, both published in a block; policy before the client ships.
Ledger: status lines for F18, P13, E11, L7, P11, F17, F14, M14, F15, E9, E10, G9; P8 cross-reference. Fixes: section 2.2 rows 75 to 88, with M15, M20 and P12 marked code, owner consensus engineer.

- 03-finality: Q2 participation from every vote seen in blocks (votes are
block payload); 3.3.2 the eclipse case closed by the 56.7% floor with the
sim v2 F2 numbers; 3.4.1 why aggregators cannot grind participation.
- 07-execution (new): EVM semantics on the DAG, shard sortition (8 provers,
10 s, then open, no shard bond), bridges (none official, no bridged
stablecoins at genesis, proof bridge with the consensus proof in phase two).
- 08-client-security (new): reproducible builds, release key in genesis and
in hardware, no silent updates, consensus only by 90% signalling, notarised
builds, official sources with the hash, seed confirmed before mining,
hardware wallet, the permanent seed line.
- 00, 02, 05, README, 06: cross-references, O-2.8 removed, O-3.3, O-3.7,
O-5.1, O-5.2, O-5.6 narrowed, O-8.1 added, counts kept at 60.
- Ledger: eight Status lines, status table, count table, overclaims 38, 40, 71.
- FUD fixes: rows 23, 26, 38, 62, 64, 66, 67, 70, 72, section 3 and 4.
- Site: bridge and stablecoin sentences no longer launch features; the seed
line wherever the app appears.

docs/spec/01 to 06 and the README index, alongside the existing overview. Section 1 is the normative
definition of the lottery hash with test vectors copied from the igneum-genesis-mh pack (cache fingerprint
48c4f5bf24166b2e, 96 hashes, mixer constants) and every prototype value marked with the measurement that
fixes it at gate 1. Sections 2 to 5 are the design as decided on 3 October 2026, labelled Designed. Section 6
lists 60 open items with the experiment or decision that closes each and its gate.
