Uvicorn Foundation

Use when porting an asyncio request-response server (HTTP/1.x, HTTP/2, WebSocket) or building the supervising shell around one — process lifecycle, graceful shutdown, worker fleets, protocol negotiation, backpressure, and proxy-trust boundaries. Source code and direct tests are ground truth; references carry decisive excerpts and graph retrieval.

Uvicorn: ASGI server kernel (lifecycle, supervision, protocol implementations)

Foundation contract

This is a cold, source-specific foundation, not an operational procedure. It is historical, revision-pinned evidence rather than timeless guidance. Current project source, tests, requirements, and runtime behavior outrank this projection and decide what ships.

Provenance and revision

Source record: uvicorn; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
Recorded revision: main@9ee5694516b01f1d3d6ff9ed38f117fc869ee6ae.
Full provenance, coverage caveats, boundaries, and preserved evidence: references/index.md.

Topic map

Representative topics: Lifecycle & supervision; Shutdown choreography; Max- requests jitter; Supervisor dispatch & import gate; Zero-downtime restart ladder; Signal-queue supervisor; Pipe healthcheck; Spawn bootstrap.
Scope and retrieval questions: references/index.md#use-this-for.
Complete capsule chooser: references/index.md#load-the-matching-source-dump.
Detailed grouped map: references/index.md#capsule-map.
Source limitations and portability boundaries: references/index.md#boundaries.

Retrieval

Open the index, choose one capsule matching the active question, and load only that capsule. Revalidate its cited source and revision before relying on it. Do not bulk-load the inventory, treat historical claims as current truth, or apply this foundation as a procedure.
