tools/txgen/run.mjs funds generated wallets from the devnet dev-fee key and sends transfers at a steady rate through
one node (nonce tracking from the pool's pending nonce, two-strike drop verdict, pool back-pressure counted as
deferred, spend cap, clean stop, summary JSON); tools/txgen/proving-watch.mjs watches the proving layer and builds the
per-block report. Two runs through the Mac node: 2,275 sent at 2/s, 2,161 included at 1.86/s (run 1), 1,650 sent,
1,633 included at 1.71/s with no failure (run 2, fixed code). Block 72704 shard 0 (29 transfers, 5,800 pgas) proven on
PC 2 in 34 s, verified on the Mac in 0.297 s, paid 1.7623 IGN.
Block 72803 (seven skipped copies, no executed transaction) failed the native-execution veto: the exporter rebuilt the
including blocks from an export that names no block, position or skipped copy's miner, sorting skipped copies out
of their block, merging consecutive blocks of one miner, dropping empty blocks (the node counts them in the link's
block index) and guessing the zero address. blocks_of now rebuilds from the 0.3.9 export's "blocks", "block" and
"position" fields (the fork change on vendor/igneum-node-txgen branch txgen-export), keeps an old export in its
order and refuses a skipped-only block without a miner. Fixtures block-72803-skipped-copies and
block-72854-empty-block-first with the node's shard plan beside each; the fixture test now checks the cut's links,
roots, gas, pgas and counts against the node's plan (shown failing on the old 72854 cut). No change under core/.

On 5 October 2026 the Mac's host (shard program id 0x0559759b...) rejected every
proof from PC 2's host (0x05db1aca...). Both were built from the same guest
sources: host/build.rs compiled the guests on each machine and the ELF depends
on where it is built (cargo's -C metadata for a path crate includes the checkout
path; a worktree on the same Mac gave a third id, 0x0dfade07...). The node's
verifier also spent 114 s to 138 s per proof in the prover client and both key
setups before a 0.1 s to 0.4 s verify.
- elf/: both guest ELFs, their verifying keys and manifest.json (sha256, ids);
host/src/pinned.rs embeds and checks them at every start; the prove modes
refuse when SP1's setup does not derive the manifest's id
- --mode verify: LightProver with the pinned key, no prover client, no key
setup; prints the proof's own program id next to ours ("IS NOT OURS")
- --mode id; igneum-prove-pin and pin-guests.sh to re-pin; build.rs builds a
guest only under IGNEUM_BUILD_GUESTS=1
- tools/ci/pinned-guests-check.sh: elf/ must match its manifest, no script
builds a guest outside pin-guests.sh; make-package.sh and build-dmg.sh print
the pinned ids
- unit tests on the pinned set; bench-log entry with the three ids, the cause
and the timing: 127.0 s wall per verify before, 1.8 s to 2.4 s after
- rollout order in proving/README.md: every prover and verifier moves together

The fact: PC 2's exporter failed blocks 58,752 to 58,843 (and the task's 58,584 to 58,984) at
shard.rs:175, "shard 0 post-root from the witness", while three empty shards were later proven, verified and
paid. Every failing block is empty: one blue block, one reward, the pool credit, no transactions, no payouts
(igneum_exportSegments 0x0..0xe738 from the Mac node, fork 2b6d23ef). The proven block 59,507 has the same
shape and the same miner as the failing 58,927. So the difference is not block content.
The rule that differed: the planner's post-root of an empty segment. The exporter on PC 2 was a stale build
whose core predated commit ed1cbb0 (the assertion sits at line 175 there and at 179 since). That planner
returned root_at(end) for a segment with no transactions, which is the pre-root; the statement applied the
rewards and the pool credit, as the node does (vendor/igneum-node-036/igneum/exec/src/executor.rs,
execute_segment) and as spec 7.7 item 8 says. Left = the root after the rewards (the node's), right = the root
before them; PC 2's export log for 58,752 shows exactly that pair. Reproduced here: master's core with that one
rule put back fires the same assertion on 58,927 with left 0x7886b9cf (the node's root) and right 0xea9db302
(the pre-root). Master's core as it is reproduces 58,927 and 59,192 with the node's roots, the host's native
mode matches the fixture, and the SP1 executor runs shard 0 to post-root 0x7886b9cf.
So the prover core needs no rule change: the fix is commit ed1cbb0, which PC 2 received with the 10:49 and
10:52 UTC rebuilds (job-rebuild-prover-pc2-037 and 037b), after which its proofs were paid. What this commit
adds is the regression and the guard for the class:
- proving/fixtures/block-58927-empty-reward.json: the failing shape cut from the devnet (33 KB).
- proving/igneum-prove/export/tests/fixtures.rs: every fixture in proving/fixtures reproduces (block
statement, plan, every shard statement from its witness, the chain of roots and links), and the empty
segment's shard ends at the root after the rewards, never the pre-root. With the pre-ed1cbb0 rule put back
the test fails. The test lives in the export crate so the core's manifest, part of the guest build, stays
untouched.
- export/build.rs and host/build.rs stamp each binary with a hash of the native sources it was built from,
printed on the first line of every run, so a stale build names itself in the log instead of in a line
number (the stale-build class of 4 and 5 October).
- docs/bench-log.md: the row under the first paid proofs.
The guest is unchanged: built in one directory, this branch and master give byte-identical loadable segments
for the shard program and the aggregator, so no prover needs a rebuild for this commit. Noted on the way and
left open: the same sources built in three directories on this Mac gave two different guest ELFs, so the
program id is not yet a pure function of the sources on a native build.

Three watchers never saw a job finish because the closing upload starts with the app header, not the SUMMARY line,
and a shard run whose stages failed still exited 0.

The intake key sits in every miner package, so the relay now lets it report only (drop text and files, ack, done,
register, upload). Posting a run or task, or renaming and re-roling a machine, needs the console token.
The prove host wrote proofs through SP1's unbuffered save: on WSL2 under /mnt/c the 18 MB core proof of a shard
took longer to save than to prove. Proofs now go through a 4 MB buffer with a timed 'saved' line, and
prove-shard.sh keeps results on the Linux side and copies them per stage. Ledger P20 updated.
Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com>
The console marked any job with a RESULT line as done, so a running shard job read as finished. Done now means
the SUMMARY line carries finished_at or the job's closing 'job <id>: <status> (exit N)' line is present.
prove-shard.sh dropped the third fixture argument (block-344-shards4) because it read only $2.

prove-shard.sh: mode shard on block-338-shard1 (execute, core, compressed), then mode block on block-341-shards2 and block-344-shards4 (compressed proof per shard, aggregation), RESULT lines with timestamps, log uploaded after each stage. PROVE-BLOCK.bat keeps the small block (mode all; the CPU comparison is mode shard now). make-package.sh packs the aggregator crate and the simnet export too; README rewritten for the shard run.

tools/prove-fixtures: a one-node simnet on ports 29300+ and a generator that lands bursts of equal-sized modexp calls, transfers and Counter increments in one chain block (blocks 338, 341, 344: 0.90, 1.80 and 3.60 S_p). block-56-transfers-3shards is a test cut at 200 pgas for the Mac CPU multi-shard check.

Two SP1 programs: the shard guest and the aggregator guest (deferred proof verification of the shard vk). Host modes native (cut, witnesses, chain and sums, three tamper checks, stub), execute (cycles per shard and for the aggregator), shard (execute, core, compressed, each verified), block (compressed proof per shard, aggregation, verified against the shard program id and the claim). Every stage prints a STAGE line and a RESULT line with a UTC timestamp so a silent gap is visible, and the host holds a Tokio runtime for the whole run and drops the proof system inside it, for the sp1-cuda Drop panic (ledger P20). The exporter writes v1 fixtures with the plan and every shard's expected roots, links and witness size; --budget makes a test cut.

The executor runs any contiguous range of a segment from a carried-in position and emits a boundary per transaction (cumulative gas and pgas, the carry link, the state root natively); the planner cuts at transaction boundaries to at most S_p pgas (provisional S_p = B_p / 4, the specification has no number yet), deterministically from the trace. Witnesses are partial Merkle Patricia tries (touched leaves in full, every untouched subtree as a hash, collapse-safe siblings carried) for the account trie and each touched storage trie; the guest rebuilds the pre-root from them, refuses any read they do not cover, and rebuilds the post-root after execution. The shard statement commits the prover's payout address (ledger P12) and the carry links; the block statement verifies the shard proofs in order, chains roots, links and transaction commitments, and carries the provers and the shard program id (design 5.1, 5.3). Port moved to igneum-exec b7fca5a0 (spec 7.5 pgas cap and abort).
