llm/ — LLM capability family

The LLM seam and its provider adapters. The interface package (llm) owns the abstract service, the content-block vocabulary, and the stream-chunk assembler; the adapters are concrete implementations that register on ctx.llm. All product packages.

Package	Role	ctx key
llm/	Abstract LLM service + content-block vocabulary + chunk assembler	ctx.llm
token-meter/	Replay-aware request and surface token measurement	ctx.tokenMeter
llm-retry/	Bounded transient request retry policy	(listens to agent/request-error)
llm-deepseek/	DeepSeek API adapter (hand-rolled fetch/SSE)	(registers on ctx.llm)
llm-pi-ai/	Multi-provider adapter via @earendil-works/pi-ai	(registers on ctx.llm)

The interface lives at llm/llm/; adapters, retry policy, and the reusable token meter are flat siblings under the group. Requests route by provider, while model is passed through to the selected adapter. The route-owning adapter optionally resolves exact provider/model context capacity; the token meter remains model-agnostic. A new provider adapter registers one or more provider routes on ctx.llm without touching the interface or consumers. See twin LLM adapters for the two shipping implementations, the replay token meter Agent Note for measurement ownership, and the routed model context Agent Note for capacity and compaction-policy ownership.
