Brings in the refreshed base (master merged through the stack after #203 and #205 landed), including the acp-snapshot extraction (#204), and re-ports this PR's snapshot-suite extensions onto the extracted package: - dsh-acp-snapshot's Scenario gains headerClass and configPath; the suite factory pins the request header PER CLASS (construction rejects a missing or duplicated class pin), forwards a scenario's configPath to the harness (RunOptions.configPath overrides AgentUnderTest.configPath), and a new fixtures meta-test asserts every pinning fixture carries exactly one request/header and no deltas. - The acp-agent example's thin scenario table re-registers code-mode-turn and both-mode-turn with their overlay configs and per-class pins; the committed fixtures replay unchanged. - The package's synthetic suites cover the new surface (explicit headerClass on one suite, the default on the other, a configPath override through the fake bin, and the two construction throws).
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 snapshot suite kit: subprocess scenario harness + golden normalizers + the defineAcpSnapshotSuite factory |
(library — imported by example *.snapshot.ts suites) |
invariants/ |
Dev-mode event-contract invariants + session-log freeze | (listens on session/*, agent/*) |
llm-replay/ |
Record/replay adapter: short-circuits llm/stream from a recorded session JSONL (keyless snapshot tests) |
(listens on llm/stream) |
subagent-mock/ |
Scripted SubagentProvider for deterministic seam/tool tests |
(registers on ctx.subagents) |
invariants runs only in dev mode (contract checks, not runtime behavior). llm-replay backs the demos and the snapshot test tier under the per-file coverage gate. acp-snapshot carries the snapshot tier's harness/normalizer/suite machinery so every example's suite is a scenario table over one shared, gate-covered implementation. subagent-mock exercises the real ctx.subagents load path without a model or child agent. A package graduates OUT of support/ into a product group only when it gains documented product consumers.
