the project lead's /live screenshot: a fixed tall box with the lanes in its top third and dead space under them. The renderer now knows
the height it wants: top padding + axis padding + lanes shown (at most maxLanes 7, narrowLanes 4 on a phone, never under 2)
times laneHeight (46 px, 40 on a phone, 26 compact; the mount option laneHeight overrides). It reports it through
onSize(heightPx, {lanes, laneHeight, narrow, compact}) whenever it changes and through getWantedHeight(); stats() carries
laneHeight, padT, padB, capacity, wantedHeight and autoHeight, so a page that sizes its own box reads no constants. With
autoHeight (on by default when the host set no CSS height on the canvas, which is read before the first size(); forced either
way by the option; never in compact mode, the app's card keeps its own height) the renderer sets canvas.style.height itself
and lets every lane through instead of fitting the lanes to the box. Every current host sets a height (/live 420, the hero
500, the app's card 220 and its Inspect view 420), so the frames are unchanged: the parity test on build-2 stayed equal on
every comparison. The site lane switches /live and the home fold to the hook.

- /live (the project lead: "make it more efficient, key at the top"): the key (Included, Excluded, Selected chain, Your block, Proven,
Locked checkpoint), the "Click to inspect · Drag to explore" hint and the window stepper sit on one row above the scene
(hint left, key centred, stepper right; on phones the key wraps and the stepper goes under it); the blue-score range stays
as a small line under the canvas; the canvas height comes from the lane count (one lane per key in view plus the others
lane, capped at the renderer's 7, 4 on phones: padT 58 + lanes x 46 (40 narrow) + padB 38, read from scene/live-dag.js
2.0.3 layout(); a sizing hook was asked of the parity lane, which owns that file); the graph column no longer stretches to
the inspector; the inspector keeps its rows with tighter spacing and Clear is a small button beside its title.
- Every other route carries the slim bar, the app's buttons, pills and cards from site.css section 10 with its content
untouched: /app (OS marks on its platform line), /miner (the download tabs take the OS wells), /miners and the bench table
(the vendor badge in front of every card name), /explorer, /block, /address (hash titles wrap), /journey, /bench, /evidence
(status pills wrap in their cell), /litepaper, /ledger (status badges wrap at 390), /claims, /randomx, /provenance, /dev-fee,
/faucet, /metamask, /404.
- Data tables fill their frame on desktop and scroll inside it on phones; no column squeezed to a sliver.
- The overlap lane's detector over all 23 pages at 390 and 1440, dark and light, on build-2: 0 overlaps.

The sweep renders every served page in a headless Chromium at 390, 768, 1024, 1280 and 1600 in light and dark (the hero at rest and at each step), reads every visible run of text and flags text covered by another element, clipped by overflow hidden, or past the viewport; a fixture with one deliberate overlap of each kind is flagged before any sweep is trusted. It runs on a build box when this machine has no browser (infra/build-server/overlap-browser.sh installs Chromium there without root).

Main, 7 October 2026: a 100 s hook gate on the merge commit against a master that moves every minute lost six pushes in a row.
Self-test: a fixture repository (unstamped branch, stamped branch, stale stamp, wrong tip, plain commit, dirty tree).

tools/scene/parity.mjs serves site/ (tools/site-serve.mjs) and the app's UI (tools/ui-mock/server.mjs) on a build box, answers
every page's /api/live from scene/fixtures/live-2026-10-07.json, freezes the clock at the fixture's instant (Date, timers,
requestAnimationFrame) and reads each scene canvas at 900 by 420 px at the first push and the next two polls: the read is the
push's own synchronous paint, so a frame depends on the fake time alone, never on how long a fetch took. Known-failed first: the
app with --included moved by one unit must differ from /live at every instant (it does: 1,549 / 1,282 / 1,157 px). Then home
fold = /live, app Inspect = /live, app with this machine's key = /live with the same key (the overlay is the same picture), and
the app's overlay frame differs from its base frame (the overlay is drawn). The compact card is rendered and reported, not
compared. A RED line names the differing pixels and their box. tools/scene/parity-remote.sh carries the files to the box
(~/.config/igneum/build-server-2 by default) under this lane's prefix and runs it there; a plain CI runner with no box and no
Playwright prints a skip line. One new line in tools/ci/pre-push.sh.
First run on build-2 at 15:4x UK, release-0.3.21 tree plus scene-parity: every comparison equal at T+0, T+2 and T+4 s.
Found on the way and fixed in the harness, not the renderer: lane order keeps the history of earlier layouts (the scene must be
at the compared size before its first layout); the app's recorded mock card is a real devnet key (cleared for the base case).
