/* Igneum DAG / Ember 2.0 (the EMBER 02 renderer pack, 7 Oct 2026). THE SHARED SOURCE: scene/live-dag.js; site/live-dag.js and
|
|
* app/igneum-app/ui/live-dag.js are byte-equal copies written by tools/scene/sync.mjs (the gate refuses a drifted copy). Edit here.
|
|
* 2.0.6 (7 Oct 2026): IgneumDag.shardWords(block, nowMs) is the one shard sentence (tooltip, /live inspector, app inspector); the
|
|
* empty case reads from the block's facts (loading, excluded, not yet ordered, off the chain) instead of one fixed sentence.
|
|
* 2.0.5 (key-22, 7 Oct 2026): IgneumDag.legend({mine}) and renderLegend(el,{mine}) are the one key both pages render; the app's
|
|
* Included swatch had been ember while the scene draws included blocks in --included, and "pending" lower-case.
|
|
* 2.0.4 (7 Oct 2026): the box's height follows the lanes. laneHeight (default 46 px, 40 on a phone, 26 compact) times the lanes
|
|
* shown (at most maxLanes, narrowLanes on a phone, never under 2) plus the axis and padding is the scene's wanted height;
|
|
* onSize(heightPx, {lanes, laneHeight, narrow, compact}) reports it whenever it changes, so a page can size the box, and with
|
|
* autoHeight (true by default when the host set no CSS height on the canvas, 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.
|
|
* 2.0.3 (scene parity, 7 Oct 2026): (1) every push, size and theme change paints the current picture at once; only the motion
|
|
* loop waits for a visible document and an intersecting canvas (a page that loads with document.hidden true, or whose embedder
|
|
* never fires visibilitychange, showed a blank canvas while reporting live). (2) The narrow (phone) rule keys on the viewport
|
|
* width, not the canvas width: a 640 px hero on a laptop is not a phone. The narrow options of 2.0.2 (narrow, narrowBreak 720,
|
|
* narrowWindow 30, narrowLanes 4, narrowMinNode 11; on a phone the window shortens until the viewer sets one, four lanes, bigger
|
|
* nodes, no hairlines but the selected chain, checkpoint labels as the percent) and the real-data presentation options of 2.0.1:
|
|
* maxLanes (own key + top keys + others, default 7), minNode (node half-size floor, default 9.5), hairlineAlpha (non-chain
|
|
* edges, default .12, drawn only within laneReach lanes, default 2, and only a merged block's first parent unless selected),
|
|
* othersScale (the others lane's size and alpha, default .75), provenGlow (a glow and ring on proven blocks, default on).
|
|
* Replacement for the supplied live-dag.js. No framework, network writes or synthetic records.
|
|
* Existing mount/push options and public methods are retained; see README.md for additions.
|
|
* Every node, parent edge, proof segment and checkpoint is derived from the observer reply.
|
|
* Motion interpolates presentation ONLY. It never promotes proof, inclusion or finality.
