ETAF Playground
The Playground exposes one canonical product example: the
examples/research-shelf.etaf and examples/research-shelf.el pair.
The .etaf file is inert, validated structural composition data. The same-
basename companion owns Components, state, theme, storage, events, and
lifecycle. etaf-playground.el is a reusable pair framework: it owns only
registration, safe loading, mounting, reset, close, and verification entry
points. etaf-playground-catalog.el is the replaceable deployment catalog;
business Components, database schemas, palettes, refs, and handlers
must stay in the companion. Compose and reuse public ETAF/etaf-ui contracts
before adding abstractions.
Run make check EMACS=/Applications/Emacs.app/Contents/MacOS/Emacs.
Run make perf for the 1413×62 warm row-selection/theme latency gate.
The example installs a deterministic 256-record SQLite fixture with 12 records
per page. Bind etaf-research-shelf-fixture-size and
etaf-research-shelf-page-size for smaller tests or larger pressure runs.
In the UI, activate Rows N ✎ to enter any value from 1 through 100. The
workspace is one responsive wrapping Flex composition: three columns when
wide, rail/list plus wrapped detail at medium widths, and vertical when narrow.
