Master removed the stdio demo (#702c8cc30) — accept the deletion; this branch's packChunks passthrough survives in acp-demo (auto-merged), and cli-demo/tui-demo arrived from master without one (the follow-up snapshot PR decides which demos expose the switch). Generated catalogs regenerated over merged sources; the hand-written session.md durability paragraph re-weaves this branch's lossless-encoding wording with master's invariant- companion sentence.
support/ — dev/test/example infrastructure
Packages that exist to serve development, testing, and the examples rather than to ship as product API. They are real workspace packages (typed, tested, under the coverage gate), but they carry lower compatibility expectations: they may change or be removed when the development need behind them does, without the deprecation care a product package would warrant.
| Package | Role | ctx key |
|---|---|---|
acp-snapshot/ |
ACP test kit: shared subprocess/client launcher + snapshot harness, normalizers, and suite factory | (library — imported by ACP e2e and *.snapshot.ts suites) |
agent-loop-testkit/ |
Shared prerequisite mounting for tests that exercise the concrete agent loop | (library — imported by AgentLoop integration tests) |
invariants/ |
Runtime event-contract assertions for development diagnostics | (listens on session/*, agent/*) |
loader-smoke/ |
Shared real-Loader subprocess harness for keyless example smokes | (library — imported by example e2e suites) |
llm-replay/ |
Record/replay adapter: short-circuits llm/stream from a recorded session JSONL (keyless snapshot tests) |
(listens on llm/stream) |
invariants is development support but has no environment guard: it runs wherever registered, and the default dsh-agent-spine-demo bundle mounts it unconditionally. agent-loop-testkit centralizes the mandatory service spine for hand-built AgentLoop tests without owning their loop or scenario. llm-replay backs the demos and the snapshot test tier under the per-file coverage gate. acp-snapshot carries the ACP subprocess/client boundary plus the snapshot harness, normalizers, and suite machinery, while loader-smoke owns the parallel real-Loader launch boundary used by keyless example e2e suites. A package graduates OUT of support/ into a product group only when it gains documented product consumers.
