igneum-labs ebd28a318c Site truth, 6 October 2026: the ledger's stated sentences merged, the bounty struck, draft (a) on the chip line, the measured prover tiers, the ledger page, the evidence page generated from its source, the live scene reading the live state
Branch site-truth-2026-10-06 = master cc178b6 + merge of ledger-text (the 45 conceded sentences of the 5 October close) + cherry-picks 6141e01, 8c5b02f (the bounty strikes) and 534463d (review round 4 reddit) + this commit. The hero chip line follows the owner's pick of 16:25 UTC (draft (a) of docs/plans/counter-asic-3-status.md section 6 with the owner's last sentence). Every number carries its source beside it. No em dashes. Site build, identity-check.sh (0 hits over 224 files) and the private-string sweep of the built pages pass.

Changed sentences, before and after (lines are master's where the sentence existed):

site/index.html:343 hero
  before: A custom chip gains under 2x, and the model is public.
  after:  The strongest recompute chip we can price, holding the whole 256 MiB cache on-die, reaches under 1x per chip against an RTX 5090. A memory-controller chip that stores the whole dataset reaches 1.2x per chip and, in our model, 5x to 9x per joule; the Ethash chips of this class reached 2.1x to 4.8x. The lever against it, program work in the latency shadow, is measured and in its gates: it brings the chip to about 2x. The model is public: the numbers.
  before: An NVIDIA card with 24 GB or more proves every block and gets paid for it; AMD and Apple cards mine.
  after:  Every NVIDIA card from 8 GB proves and is paid for it; 12 GB and up mine and prove; 24 GB on the stock server (eleven rented cards, RTX 3060 to RTX 5090, 6 October 2026, docs/analysis/prover-tiers-real-cards.md). AMD and Apple cards mine.
site/index.html:372  before: miners active  after: vote keys active in 10 min (a card runs several)
site/index.html:400 and the chain scene script  before: the "proven" and "locked" counters counted the simulation while the scene carried the live label  after: in live mode the counters read the observer (proven = blocks in the window every shard of which is verified, "not active" while the proving layer is off; locked = locked checkpoints in the window) and the simulated shard sparks stop
site/index.html:484  before: One click. The card mines; an NVIDIA card with 24 GB proves too.  after: One click. The card mines; every NVIDIA card from 8 GB proves, 12 GB and up mine and prove.
site/index.html:492 and site/miner.html:266  before: (the app is still labelled Igneum Miner until 0.3.6)  after: (the app window still says Igneum Miner at 0.3.13)
site/litepaper.html:301 abstract  before: A custom chip gains under 2x, and the model is public; the claim is tested by paid independent cryptanalysis and the public benchmark.  after: draft (a) as on the hero, then the sources (chip-model-v3.md section 5; the Ethash rows of asic-resistance-history.md; Counter ASIC 3.0 item 8), then "The model is public; the claim is tested by paid independent cryptanalysis and the public benchmark."
site/litepaper.html:396  before: About one a second  after: About one a second with the full fleet; 0.65 a second over the hour to 16:00 UTC on 6 Oct 2026 with one PC off (the live page's hour count, 2,325 blocks)
site/litepaper.html:400  before: version 0.3.5; 0.3.6 staged  after: version 0.3.13 (6 Oct 2026); the app window still says Igneum Miner
site/litepaper.html:412  added after "not on maths or bandwidth.": Measured: an RTX 5090 hashes at 95 GB/s of useful 4-byte loads against 1,638 GB/s of sequential writes (engineering log, the RTX 5090 entries).
site/litepaper.html:424  before: It claims the gain is small, the response takes a week, and both are measured.  after: It states the gain its own model finds, the response takes a week, and both are measured.
site/litepaper.html:440 (vs RandomX, Useful work)  before: NVIDIA cards with 24 GB or more prove every block and sell proofs to other chains; AMD and Apple cards mine, ...  after: Every NVIDIA card from 8 GB proves; 12 GB and up mine and prove; 24 GB on the stock server (eleven rented cards, RTX 3060 to RTX 5090, 6 October 2026, docs/analysis/prover-tiers-real-cards.md); they sell proofs to other chains. AMD and Apple cards mine, ...
site/litepaper.html:452  before: Proving needs an NVIDIA card with 24 GB or more (32 GB until the fee switch of 6 October 2026; ...). AMD and Apple cards mine. A prover for them lands when a zkVM ships one.  after: Proving: every NVIDIA card from 8 GB proves; 12 GB and up mine and prove; 24 GB on the stock server. Measured on eleven rented cards ...: the RTX 3060 (12 GB) mines at 23.78 MH/s and proves the v1 shard beside its miner at an 8.9 GB peak in 37.5 s; the RTX 4060 (8 GB) proves it alone at 7.4 GB in 18.4 s; the RTX 4090 (24 GB) proves it on the stock SP1 server in 5.6 s at 17.4 GB. The patched server that fits the smaller cards is not yet in the shipped app. AMD and Apple cards mine. A prover for them lands when a zkVM ships one.
site/litepaper.html:454  before: The old 12 GB gate on the roadmap is withdrawn until a prover build with a smaller floor is measured.  after: ... was withdrawn on 5 October until a prover build with a smaller floor was measured; on 6 October a patched server proved the same shard at 7.4 to 8.0 GB alone on eleven rented cards from the RTX 3060 to the RTX 5090 (the real-card table), so the gate returns as measured and the patched server is not yet in the shipped app.
site/litepaper.html:562 (Hardware)  before: 24 GB proves full shards (measured on a 32 GB card's allocation; a 24 GB card has not run it yet) and 32 GB mines and proves on one card, measured 5 October 2026 on this prover build (a 12 GB card does not prove on it: the GPU prover's floor is 13.9 GB).  after: Every NVIDIA card from 8 GB proves; 12 GB and up mine and prove; 24 GB on the stock server (eleven rented cards, RTX 3060 to RTX 5090, 6 October 2026, docs/analysis/prover-tiers-real-cards.md).
site/litepaper.html:645 (Governance, admin keys)  appended: On the devnet the activation heights and one execution-state restart (6 October 2026) reach every node through the signed update manifest, so on the devnet the release key acts as the operator; the sentence above holds for mainnet consensus only once that path is closed, and the public testnet terms will say which parameters still travel that way.
site/litepaper.html, Questions miners ask  added: the entry "Don't ASICs make a chain safer?" (three parts and a five-row table; the rental row cites the fleet's bench entry that lands tonight and the 50-miner wave row reads "measurement tonight")
site/litepaper.html:733 (What Igneum does not claim, the chip item)  before: ... approximate; the claim is under 2x, the margin is stated on the numbers page, and the next lever is named there. No hash has stayed free of chips forever; Igneum does not claim to. Monero's seven years without a public chip are precedent, not proof.  after: ... approximate. The same model, drawn out to the chip that stores the dataset (6 October 2026): draft (a) with its sources. No hash has stayed free of chips forever; Igneum does not claim to. Monero's seven years without a public chip are precedent, not proof, and a small prize: they say nothing about the price of a chip with the 256 MB cache on its die, and that price is a cost model, not a measurement.
site/litepaper.html, the four bounty sentences (301, 424, 684, 686): struck as on ca2-coord 6141e01 and 8c5b02f
site/litepaper.html, the 45 sentences of the 5 October close: as on ledger-text 2404bde (merged)
site/miner.html:7, 13, 21 (meta)  before: and an NVIDIA card with 24 GB proves.  after: and every NVIDIA card from 8 GB proves.
site/miner.html:252  before: Install. Start. The card mines. An NVIDIA card with 24 GB proves too.  after: Install. Start. The card mines. Every NVIDIA card from 8 GB proves; 12 GB and up mine and prove.
site/miner.html:308  before: ... and, on an NVIDIA card with 24 GB or more, the prover. AMD and Apple cards mine;  after: ... and, on an NVIDIA card, the prover: every NVIDIA card from 8 GB proves; 12 GB and up mine and prove; 24 GB on the stock server (eleven rented cards, ...); the patched server for the smaller cards is not yet in the shipped app. AMD and Apple cards mine;
site/evidence.html  before: hand-kept, "30 claims · 4 Oct 2026", row 21 "unwritten"  after: generated by site/build.mjs from docs/evidence.md (31 rows, the counts, the date), scrubbed as /bench is
docs/evidence.md row 17  before: The chip resistance target: a chip gains under 2x over a GPU  after: The chip resistance claim: the strongest recompute chip under 1x per chip against an RTX 5090; the stored-dataset chip 1.2x per chip and 5x to 9x per joule in the model (2.1x to 4.8x by the Ethash precedent); the latency-shadow lever, measured and in its gates, brings it to about 2x
docs/evidence.md  the card-lifetime row numbered 22 under "What moved on 5 October" becomes row 31 of the table; "Hetzner VMs" becomes "cloud VMs", "recommended to the project lead" becomes "recommended to the owner"
docs/fud-ledger.md, docs/fud-fixes.md  taken from fud-close b3acfb5 (167 entries); two lines reworded for the identity check (the log key, the log intake)
site/ledger.html  new: every ledger entry with the critic's words, what was done, the status and the date, the count table on top (53 conceded, 54 fixed or built, 27 closed by rule or decided, 13 answered with evidence, 13 by design, 7 open); generated by tools/ledger-page.mjs
site/vercel.json  the /ledger redirect removed
site/partials/footer.html  "Ledger: every criticism" added under Read (so every page's footer changed)

<h1>Live devnet</h1>
<p>A node is read every two seconds. Every block below is real: its parents, its miner, whether it sits on the selected chain, and whether it is a locked checkpoint. A checkpoint locks when the finality rule's quorum signs it. Once the proving layer is activated, every chain block's shards show as they are planned, proven and paid.</p>
<p>Fees: the devnet meters with its prototype table until DAA score 210,000; from there the adopted table applies (300 pgas per transaction, 30,000-pgas shards, floors of 100 gwei per gas and 10,000 gwei per pgas) and the provers' program carries both.</p>
