7717c4fdac Windows CI: the one-click app built on GitHub runners, no PC needed
windows.yml: parse job (every .ps1 through the Windows PowerShell 5.1 parser with a negative fixture, PSScriptAnalyzer
as warnings, parenthesis check of every .bat/.cmd with a negative fixture), build job (engine on the MSVC target,
window host through BUILD-APP.bat as it is, payload through make-payload.sh in Git Bash, installer through
build-installer.ps1, smoke run of both exes, launcher DRY_RUN, three artifacts for 90 days).
push-inputs.sh publishes payload-inputs.zip (node, miner, workers, NVRTC DLLs) to the downloads host from the Mac;
fetch-ci-artifacts.sh pulls the green run's installer and payload back into the downloads folder.
Host: --version and --help, version.h shared with host.rc. Launcher: DRY_RUN=1 prints the plan and starts nothing.

3e03e9bff7 Live DAG: chain rail layout, time ruler, slide-in, red as ember tint, pending count
The selected chain runs along one horizontal rail; crowded chain blocks
stagger to three rows around it. Side blocks hang above and below in time
order, packed into rows so none overlap. The miner is the ring colour; the
gutter lists active miners with their on-screen block counts. A ruler under
the blocks ticks every 5 s with clock labels and now at the right edge. New
blocks slide in from the right. Red blocks are a dim ember tint. Header stats
gain a pending count. Density steps, tooltips, final band and the one-rAF
loop are unchanged.

748912af9c Prover package: PROVE-SHARD.bat runs the shard at S_p and the two- and four-shard blocks on the GPU
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.

b64a31c77f Proving fixtures: blocks of one, two and four shards at S_p from a private simnet, plus the v1 cut of the v0 blocks
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.

f71af23dcb Proving: aggregator guest, host modes shard and block with per-stage timestamps, exporter with shard plans
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.

9bea7c718b Proving: shard cutter, MPT witnesses, shard and block statements in igneum-prove-core
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).

53f7f55796 Relay: text, files and runnable tasks between the Mac, the PCs and the phone (relay.igneum.network)
New Vercel project igneum-relay from relay/: one function (api/relay.mjs) over Neon tables relay_items and relay_machines,
files in Vercel Blob store igneum-relay (50 MB client uploads, 4 MB through the function), phone-first web page at /r/<token>/
with the site tokens. Mac CLI tools/relay.mjs (feed, read, drop, task, run, watch, inbox, machines, role, name).
Windows clients send.bat/send.ps1 and the igneum-agent (registers hostname, role, GPUs, WSL, nvcc; runs queued PowerShell
scripts, posts results, reboot-continue via scheduled task + RunOnce), bash twins send.sh and agent.sh (verified live),
playbooks for WSL setup, prover setup, prove-block, miner v4, one-click placeholder. make-clients.sh bakes the secrets
into a zip; the repo copies hold placeholders. Screenshots under docs/design/relay.

70bed1065a CI on every push: igneum-pow tests, census build, simulator quick modes, site build + link check, identity grep
GitHub Actions workflow (.github/workflows/ci.yml) on push and pull_request with three jobs on the free runners:
igneum-pow `cargo test --release` and the igneum-census build; the two Python simulators' --quick modes under a
120-second timeout; the site build, an internal link check of site/*.html (tools/ci/link-check.mjs) and a gh-free
identity grep of the public export list (tools/ci/identity-check.sh over tools/ci/forbidden-strings.txt: machine
names, LAN and overlay addresses, home paths, local time zones, the log-intake key pattern; never a key or a name).
The node fork is too big for CI today and the workflow says so.

sim/finality_v2.py --quick is now a genuine smoke run (one day or hour per scenario, one partition and one eclipse
setting): 149 s at nice 19 on a loaded Mac, was 745 s. sim/difficulty/sim.py gains --quick (up50 and warmup-hard,
kaspa and igneum controllers, 36 s). One bench-log time-zone label reworded so the identity grep passes.

56d6dc6efe Windows package 0.3.0: prebuilt one-click workers first, nvcc/cl.exe build path as the fallback
igneum-common.ps1 uses igneum-worker-cuda.exe (with nvrtc64_*_0.dll next to it) and igneum-worker-opencl.exe when they
are in the folder, passes the exported pack with --pack, and only surveys the toolchain (Find-Toolchain) when a worker
is missing or FORCE_BUILD=1; the dashboard and the status block name the path per card; a prebuilt worker that is not
ready after 150 s falls back to the build path once when a toolchain exists; 90 s of seed mismatch errors re-export
the pack and restart the vendor; WORKER_ARCH overrides the NVRTC target. make-package.sh ships the two exes, the two
NVRTC DLLs, the licence texts, THIRD-PARTY.md and TEST.md (what the first RTX 5090 run should print and what to send
back). README.txt, the bats, proto-cuda/README.md (nvrtc/ section), WINDOWS-MINER.md and the bench log updated with
what the Mac measured.

079ed76a2d OpenCL worker: generic --pack serve mode and OpenCL.dll loaded at run time (one-click AMD worker)
host.c --serve --pack <dir> serves a pack read at run time (packfile.h), whatever pack the exe was built against: the
first pair is built and self-tested like a prepared one (pairBuffers, pairSelfTest), prepared pairs are self-tested
too, the ready line says path prebuilt-generic. cl_dynamic.h (IGNEUM_CL_DYNAMIC) opens OpenCL.dll with LoadLibrary and
fills a function pointer per entry point, so the mingw build links no import library. test-generic.sh checks the mode
through Apple OpenCL with the packs of the CUDA emulation test: PASS (192 found, prepare and swap, 15 sampled hashes
equal igneum-pow hash-bound), built against a different placeholder pack than it served.

f535abb59d One-click CUDA worker: driver API + NVRTC loaded at run time, pack read at run time, Mac emulation check
proto-cuda/nvrtc/worker.cpp serves igneum-miner's worker protocol with nothing installed but the NVIDIA driver:
nvcuda.dll and the redistributable nvrtc64_120_0.dll are opened with LoadLibrary (cuda_api.h), the pack's kernel.cu
and kernel_bound.cu are handed to NVRTC byte for byte up to the host launch wrappers with program.h and memhard.h as
named headers, every pack is self-tested against its vectors.h (cache head, last line, FNV-1a 64, dataset head, last
word, 64 samples, 96 vector lanes) before it serves a job, prepare runs on a thread for the hourly swap, and a job on
seeds without a pair makes the worker find the miner's pack by seeds.txt and build it. packfile.h (C99) reads a pack
directory. fetch-redist.sh verifies and stages the NVIDIA 12.8.93 redistributables and the Khronos headers
(THIRD-PARTY.md records URLs, hashes and the EULA clause); build-windows.sh cross-compiles with mingw (static,
KERNEL32 + Universal CRT only). emu/: the two libraries as host functions, the pack kernels on host threads, the NVRTC
source compared with the pack files; test.sh PASS on the Mac (two real packs, swap, self-heal, 17 sampled hashes equal
igneum-pow hash-bound). Not run here: the real NVRTC compile and driver load (RTX 5090 PC).

309ac87990 Live page: block DAG redrawn for 20 miners at 4 blocks/s
One lane per miner ranked by share, overflow in an others lane with a count.
Lane labels in a left gutter in the miner's colour (3-character tag on phones).
No per-block labels: short id on the chain tip, the lock, and on hover or tap
with a canvas tooltip (id, blue, DAA, parents, chain or side). Same-lane
overlaps nudged in a fixed sequence. Chain as one path, side blocks linked to
their first parent only, clamped cubics so no edge becomes a tall loop. Block
size and time scale step down together at density. One rAF loop, DPR aware,
paused when hidden or scrolled out. Final band and lock marker. Before and
after screenshots in docs/design/live-dag.

1d018c601c Finality: the total-weight floor is two thirds (O-3.15 decided, 4 October 2026)
A lock needs two thirds of all 30-day weight signing; finality pauses
whenever less than two thirds is connected and signing, the chain runs
on proof of work meanwhile and the node reports it. Spec 3.3, 3.3.1,
3.7, 3.9, 3.10 Q3 row, 3.11 rewritten with the new arithmetic (safety
one third in every view, liveness two thirds connected, the per-view
window bound stated as 3.7 item 9); O-3.15 decided, O-3.16 closed,
O-3.18 and O-3.19 narrowed. Simulator: --floor, the +local partition
mode, scenario L; A to L re-run at the 2/3 floor over five seeds with
the 0.85 deltas in results_v2.md. Litepaper finality sentences and the
'does not claim' item. Ledger F2, F9, F16, F18 restated, F21 added
(the window bound and the post-heal finality fork from the devnet).
Bench-log: node build and tests, simulator deltas, three-node six-voter
runs of 6A, 6B and 6A with a long heal on ports 29200 and up.

ff9caee488 Seed v4 staging: no pipes after the build (the v4 igneumd --version exits 1), unpack stamp, resume mode
The first stage run built v4 on igneum-seed-1 in 60 min 49 s and then failed on `igneumd --version | head -1` under
pipefail, because the devnet-v4 igneumd prints its version and exits 1. The post-build steps now write to files and
test them; the tarball is unpacked once per src.stamp so a rerun is incremental; `stage-v4.sh <seed> resume` reruns
the build script on the tree already on the VM and then waits and installs.

38380d9035 Release: devnet v4 cut-over staged (Windows 0.2.0 packages, Mac app 0.2.0, seed igneumd-v4 unit, runbook)
Windows combined package 0.2.0 (proto-cuda/windows-app): v4 exes from target-integration, peers = seed then Mac,
fresh appdir devnet-v4, one miner and one worker per card with --identities 8, --evm-address (PAYOUT_EVM or derived
per vendor from the PC name), voting on (VOTE=0 opts out), --prepare-packs for the hot swap with --exit-on-seed-change
as the fallback, --yes on the node, STATUS regex tolerant of the v4 now= segment, version in the dashboard header.
Mac app 0.2.0 (packaging/mac): v4 binaries, Metal worker rebuilt for macOS 11, data folder devnet-v4, EVM payout,
identities in one process, synced= flag honoured. Seed (infra/seed-nodes): stage-v4.sh builds v4 on the VM as a
niced, memory-capped transient service and installs a disabled igneumd-v4 unit with a fresh data dir; switch-v4.sh
swaps the units (--back reverses); health.sh reports active-v4. Runbook: docs/plans/cutover-2026-10-04.md.

2622fd2ccb Difficulty: timestamp attack fixed in spec 2.3, simulator, analysis addendum, ledger M23
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.
