Pi Mono Foundation

Use when porting agent-loop, event-stream, provider-retry, context-compaction, branch-summarization, tool-batch-execution, auto-compaction wiring, Anthropic wire-compat/message normalization, session-storage backends, extension tool-wrapping, Vertex AI auth/ADC ladders, Azure OpenAI Responses twin deltas, Codex WebSocket resume transports, provider OAuth refresh contracts, or cross-model message-history preshaping from badlogic/pi-mono — capsule-v2 source maps with decisive excerpts and graph retrieval.

pi-mono: agent-runtime 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: pi-mono; portable upstream identity, license, coverage caveats, and retrieval history are preserved in the index.
Recorded revision: main@80e62761f7251a104f1b21d9c73920c720f0ec00.
Full provenance, coverage caveats, boundaries, and preserved evidence: references/index.md.

Topic map

Representative topics: EventStream kernel; Provider retry ladder; Agent loop semantics; Compaction trigger & safe cut; Repeated compaction; Branch summarization; Anthropic message normalization; Anthropic wire-compat ladder.
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.
