igneum-prove-core carries the node's fees.rs (PgasTable, FeeParams PROTOTYPE and CALIBRATED_V1,
FeeSchedule::at); the shard input and every fixture carry the schedule and the block's DAA score; the executor
reads the set at that score, raises the base fees to its floors and meters with its intrinsic, B_p and modexp
entry, as the node's execute_segment does. The 328-byte statement is unchanged: the node's native veto pins the
schedule (a new layout would be a consensus change for every node). Exporter: schedule and daaScore from the
dump (gen.mjs writes them), per-segment switch on replay, S_p from the set. Fixtures from one simnet chain across
the switch at DAA 800: fees-switch-prototype (block 51), fees-v1-shards2 (351), fees-v1-shards3 (355); 358
segments replayed, every state root the node's. Host tests on both sides. Guest re-pinned: shard
0x2b1a81cb..., aggregator 0x474678f3...; pinned-guests-check passes.
Node fork 2b6d23ef unchanged (igneum-exec tests 11 passed). Digest for the override with
fees_v1_activation_daa 210000: ab8847da538dead1dc10e046dfaadab3c1c35928e3748810c4e050d4a886087a.
Runbook docs/plans/fee-switch-devnet.md; infra/devnet/restart-hand-nodes.sh and restart-seed.sh take the
override object (the hand nodes and the seed run 20139145 today and must move to 2b6d23ef first). One line on
the live page, spec 5.11, the testnet README, the floor analysis, the bench log and the journey.
