The shared test module was named harness.ts inside a repo whose product
IS a harness — hopelessly ambiguous. Renamed to scaffold.ts with
launchWebScaffold/WebScaffold; tsconfig plane-split entries, the seam
JSDoc/README mentions, and both Agent Note languages updated.
Both scenarios gain a Playwright interaction step over the settled
transcript (after the golden capture, so committed aria surfaces stay
untouched): replay-round-trip clicks the reasoning fold open/closed over
wire-delivered state; seeded-history expands a read tool row rebuilt from
the cold log and asserts the recorded result text appears (read rows are
expand-in-place — rowExpands routes the click to the inline fold, not the
details column). test:web 30 passed | 1 skipped.
apps/web/tests/harness.ts boots the real web assembly in-process
(startHost llm:false -> installLlmReplay providers-mode -> mountWebPlugins
-> startWebServer) under DSH_SNAPSHOT replay/record/refresh. Barrier
stack: in-process turn/end -> agent.whenIdle (covers the persistence
flush) -> browser settled-poll. Seeding goes through the real persistence
API (semantic-checkpoint precedent); record harvests fixtures from live
session memory and tokenizes {{sessionId}}/{{cwd}}; refresh is the sole
golden writer. Console tripwires fail scenarios on reconnect/gap-repair
self-healing; harness close asserts full replay-fixture consumption.
Scenarios, each with fixtures recorded against THIS assembly via a live
model run: replay-round-trip (real composer -> real bash echo -> settled
markdown + aria golden + world-state event asserts) and seeded-history
(cold sidebar list -> implicit resume on open -> history tool cards from
the log, zero model calls). apps/web/tests are host-plane programs:
excluded from the client-registered apps/web project, included in
tsconfig.host.json (one program cannot hold both Context merge sides).
