site/lib/emission.mjs is the emission rule as igneum.rs computes it (block_subsidy, launch_ramp, an exact floor-sum for
minted-so-far); its tests reproduce the node's own test values and a devnet coinbase (block 2622db76: payload 454,486,399
at DAA 125,064, outputs 454,485,299 = E(125,063), what the merged parent declared). Every live_blocks row gains tx_count,
evm_miner (the IGNA tag, else the vote key's low 20 bytes), proof_records (IGNP section), subsidy_sompi, paid_sompi,
selected_parent, number, detail. No extra RPC per block: measured 282 against 283 wRPC and 785 against 776 EVM calls
per minute before and after. live_state.rpc_load and live_state.supply_check are new.

Observer (tools/observer/observer.mjs): reads the execution layer's JSON-RPC of a node on the proving build
(IGNEUM_EVM_RPC, default the Mac app's node 26800): every chain block's shard plan as it joins the chain
(igneum_getShardPlan by blockHash, one live_proofs row per shard, planned), the proof records of the chain
blocks of the last 10 minutes polled in rotation (igneum_getProofRecords, four in flight, 40 blocks per tick
while active, 10 before activation): proving (in the pool), verified (SP1 proof verified, or carried and checked
by consensus), paid (a carrying segment paid it), with the prover's id8, the carrier, lag in DAA and the payout.
live_state.proving = {supported, active, activation_daa, tip_daa, verifier, pool, blocks_10m,
blocks_fully_proven_10m, shards_proven_10m, shards_paid_10m, median_proof_lag_s, provers_10m}. A node without
the RPCs gives supported false (rechecked every 5 min); an unreachable endpoint is retried every 20 s. Events:
proving (activation, first paid shard), prover_seen. Additive schema (live_proofs, live_state.proving).
API (site/api/live.mjs): proving, and per block shards: [{i, n, state, prover, lag, payout (IGN), pgas}] and
proven; ?window=N (30 to 300 s) for the page's diagnostic long view; LIVE_TABLE_PREFIX reads a test observer's
tables.
Live page (site/live.html), the design change of 4 Oct 2026: three thin strips sharing one time axis, newest at
the right. BLOCKS keeps the per-miner lanes, chain path, blue/red/pending colouring, arrival glow and tooltips;
the lock ring, dashed lock line and final band leave it. FINALITY is an 18 px bar: ember wash = final (up to the
newest locked checkpoint on screen), molten tick = locked checkpoint, faint = proposed, one label at the newest
lock ("locked #522, 12 s ago"); while finality is not active it reads "finality paused: N% of weight silent" and
nothing else (R4.6.3). PROVING shows one cell per shard under each chain block, outline (planned), molten
(proving), prover colour (verified), tick (paid), a dashed "proofs land N s behind the tip" line, or the one
honest line before activation ("Proving layer: not yet activated on this devnet; activation at DAA N" / "node
without proving"). Header stats: on screen, chain, identities, last lock, proven. Legend: one line per strip.
Hover and tap tooltips on blocks and cells (block, shard, prover, lag, payout). Lanes snap on resize (they used
to ease from a zero-height layout). Phone width, no horizontal scroll; draw 0.6 ms avg, 1 ms max with 110 blocks
on screen (playwright, 1280 px).
Hero (site/index.html): a faint second glint behind a real block once every shard of it is verified, only while
the proving layer is active; pace and sampling untouched.
Verified on the private 3-node proving network (tools/proving-v0/run.mjs --network-only, activation 60) with a
CPU prover loop signing as v0/v1/v2: records relayed, verified on node 0, carried and paid (block 155 by 405,
lag 259 DAA, 0.634 IGN); screenshots in docs/design/live-proving (devnet before activation at 1280 and 375 px,
test network active, the ?window=300 view with paid cells). The live devnet shows the "not yet activated;
activation not set" line once the observer runs this build.

After the 4 Oct 2026 stall (no block stored from 11:57 to 13:15 UTC, then 7,022
blocks in two minutes). Notifications only enqueue; a drain loop handles them
in bounded batches. Block flush, colour marking and certificate work each run
on their own timer and never wait on one another. Mergesets come from the
notification's verbose data (bounded cache); getBlock only on a miss, four at
a time. live_state gains observer_lag_s and queue_depth; the API serves them;
the page shows "observer N s behind" past 30 s instead of waiting for the
first block. blocks_per_minute and blocks_60s are bucketed by the block's own
timestamp and reseeded from the table on start, so a catch-up fills past
minutes instead of painting a spike. If no blockAdded arrives for 60 s while
the node's block_count advances, the observer resubscribes; after two failed
attempts it exits 2 and tools/observer/run.sh restarts it.

Observer: additive live_blocks.color (pending by default). Every chain block's
mergeset marks its blues blue and its reds red, from the notification's verbose
data or getBlock for chain blocks learned via virtualChainChanged; a reorg puts
the removed chain blocks' mergesets back to pending. API serves color. Page:
blue side blocks filled in the miner's hue at 70% with the ring, pending the
faint outline, red a dark outline with a strike; tooltip and legend name the
state.

site/verify/core.js recomputes every header hash (keyed BLAKE2b, the
node's field order), checks the parent links from the previous locked
checkpoint, hashes each voter's G1 key to its vote_key_hash, verifies the
BLS aggregate over "igneum-vote-v1/" || chain_id || 0 || index_le64 ||
checkpoint under the vote tag with the bitmap's keys, and applies Q3
(2/3 of active, 17/30 of total). verify.js drives it from /api/checkpoint
with @noble/hashes 2.4.0 and @noble/curves 2.4.0 pinned from jsdelivr and
fills the homepage card; the badge says LIVE only after a pass in the tab.
site/api/checkpoint.mjs ships the data: certificate bytes, voter table
with public keys, header chain. tools/observer stores every certificate a
block carries (new table live_certificates, voter table read at the lock,
selected-chain headers back to the previous lock, one-off backfill of the
newest lock on start) and keeps header nonces exact; the FinalityLock
write no longer fails on a missing votes_seen.
Tested on the igneum-devnet-7 test network: checkpoint 95 verifies in
Chrome in 103 ms; a flipped signature bit, a dropped voter, an altered key,
an altered header and a removed header all fail with the reason named.
