Introduces examples/acp-agent/src/llm-replay.ts, a function/namespace plugin
that installs a single llm/stream waterfall listener. In record mode it tees
the real model's StreamChunks into a per-scenario llm.json (flushed atomically
after EACH stream, since the snapshot subprocess is SIGKILLed and start.ts has
no disposal path). In replay mode it short-circuits the waterfall and serves
recorded streams back positionally — the Nth stream() call gets the Nth entry —
so a snapshot test can drive the real agent with no API key.
Each fixture entry is a discriminated record {chunks|throw|hang} so it can
replay BOTH branches of the LLM failure contract (throw from stream() vs a
finish-error chunk) plus cancellation. A throw entry carries the prefix chunks
emitted before the throw, replayed before the error, so a mid-stream failure
(partial output then STREAM_CLOSED) reproduces what the loop saw live.
Fail-loud on a missing or exhausted fixture (never a silent skip). Unit tests
drive the real LlmService waterfall (record tee, ordered replay, the three
entry kinds, partial-then-throw, fail-loud, event-driven abort, HMR-safety).
Broadens the unit vitest include to examples/*/tests and registers the plugin
+ snapshot tests as knip entries. Per docs/rfc/implemented/2026-06-19.

// mapping exists is the root tsconfig.json `paths` map inherited by
|

// tsconfig.test.json. The native option is a bare boolean: for each
|
|
// importing file it discovers the NEAREST tsconfig.json and applies that
|
|
// file's own `paths`. Every workspace under packages/* and vendor/* has its
|
|
// own tsconfig.json without `paths`, so native resolution maps nothing,
|
|
// falls through to package.json exports (lib/, absent until `pnpm run build`),
|
|
// and every test file fails to import (verified on vite 8.0.16 /
|
|
// vitest 4.1.8). Making it work would mean copying the paths map into all
|
|
// 15 workspace tsconfigs — including vendor/* ones, which are pinned
|
|
// upstream copies (vendor/README.md). The plugin's `projects` option
|
|
// instead applies the one root map to every importer.
