Fastapi Foundation

Use when porting FastAPI's request machinery (Python ASGI web framework) — the dependency-injection solver and cache, signature-to-param classification, body/query validation, response dispatch and streaming (JSONL/SSE), lazy router composition with prefix/dependency inheritance, or OpenAPI schema generation — into another framework or service. Source code and direct tests are ground truth; references carry decisive excerpts and graph retrieval.

FastAPI: Python ASGI web framework foundation

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: fastapi; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
Recorded revision: master@c3f316b7e814667e8ee81e03a7330d00ee61e45c.
Full provenance, coverage caveats, boundaries, and preserved evidence: references/index.md.

Topic map

Representative topics: Dependency solving; Param & body validation; Lifecycle; Routing; Responses & streaming; Encoding & schema generation; Compat & diagnostics.
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.
