What triggers the terrain to be updated on the fly when, for instance, adding a new breakline?
Editing referenced data inside an edit session creates tile-based dirty areas in the terrain. It doesn't rebuild automatically; you have to execute the process. The Terrain Properties dialog box in the Catalog window and the Layer Properties dialog box both report whether a terrain needs to be built. There's also a dirty area renderer available for the layer, accessible from the Symbology tab. After editing participating feature classes, run the Build Terrain geoprocessing tool or use the Build button on the Update tab of the Terrain Properties dialog box in the Catalog window.

Does build performance for a terrain dataset improve when a multipoint feature class is embedded?
Using embedded feature classes does not improve performance. Embedded feature classes offer two primary benefits: help reduce storage requirements, since you can remove the source multipoint feature class after the terrain is built, and ensure BLOB-based attribute values are properly handled relative to edits/updates.
If I append a multipoint feature class to a terrain dataset using the Add Points To Terrain geoprocessing tool, will the binary attributes also be appended?

Why are terrain datasets not supported in ArcScene?
ArcScene requires that the elevation source data reside in memory. Terrain datasets utilize an on-the-fly query and display structure to work efficiently with millions or billions of points. Consider converting a terrain or portion of a terrain to either a TIN or raster-based surface for use in ArcScene.
When building a terrain, there is a changing fraction value to indicate progress. What determines the size of the denominator displayed in the progress window?
What does each phase indicate during the build process?
The first phase scans through all tiles. The tiles whose extents are completely covered by data have pyramid levels built. During this first phase, it is determined which tiles are completely or partially void of data. The second phase composites and builds pyramid levels for empty tiles. The third phase builds the partial tiles.
