Add a proposed architecture RFC to make the examples folder thin: each example becomes mostly an invocation of an app package. A shared dsh-agent-core bundle owns the providerless spine; dsh-stdio-agent and dsh-acp-agent app packages bake in their coupled front-door cluster (UI + logger/hmr policy + agent pre-creation), turning the ACP stdout-purity footgun into a property of the artifact. Leaf cordis.yml shrinks to backends + config; start.ts is dropped in favor of a package bin. Supersedes the providerless-example-base RFC (cross-linked) and indexes the new RFC under Proposed -> Architecture.

RFC: Make the shared example base providerless
Status: proposed
Superseded by Extract example apps into packages: moving the spine into a
dsh-agent-corebundle and deleting thebase*.ymlfiles makes the rename below moot. Kept for the record.
Problem
The examples have two shared base files: examples/base-core.yml is providerless, while examples/base.yml includes that core plus the real llm-deepseek adapter. Snapshot replay needs the providerless core with llm-replay, because loading the real adapter without a key throws. The normal demos need the real adapter. The result is a naming inversion: the file named base.yml is not the reusable base for all examples, while the true base is base-core.yml.
The split is understandable, but it makes every config explanation longer. It also leads to awkward test setup like a keyless smoke test carrying a dummy API key so an adapter can boot even though the model is not called.
Proposal
Rename the providerless core to examples/base.yml and make adapter selection explicit in each concrete example. The coding and ACP real configs add a tiny llm-deepseek include or local block; snapshot config adds llm-replay. Delete examples/base-core.yml.
The shared base should contain only provider-neutral services and tools: llm, sessions, system prompt, tools, agents, invariants, bash executor, and bash tool schemas. Anything that chooses a model provider belongs at the leaf config.
Acceptance criteria
- examples/base.yml is providerless.
- examples/base-core.yml is deleted.
- Real demo configs explicitly add the DeepSeek adapter.
- Snapshot replay config includes the same providerless base and its replay adapter.
- The examples README, example-specific READMEs, and RFC references stop explaining "base = base-core plus adapter".
What we give up
Real demos lose one layer of convenience: each must opt into the adapter. That is the right default for examples, because adapter choice is the variable part and providerless wiring is the shared product core.
