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).
Root tsconfig.json becomes a pure solution (files:[] + two references);
the former root host aggregate moves verbatim to tsconfig.host.json.
New tsconfig.base.client.json carries the shared client compiler shape
(jsx/DOM lib/types:[]), and tsconfig.client.json plus the 12
packages/client tsconfigs extend it instead of restating the trio.
tsconfig.build.json is deleted: the solution covers the full emit graph,
absorbing the command-goal typecheck/build drift.
Consumers migrate to the single graph: typecheck/build scripts and the
lefthook pre-push hook run bare `tsc -b` (pre-push now covers the client
side); the run-gates build gate needs typecheck so two concurrent tsc -b
runs cannot race the same tsbuildinfo; ts-project.ts and the standalone
doc-typecheck mode seed tsconfig.host.json explicitly (never the root
solution — flattening host+client into one program collides the cordis
Context merges); verify-cordis-config BFS seeds the root solution alone.
