Agent & Instrument Diagram

How do agents and instruments orchestrate venture creation?

Nomenclature

A&ID ElementInstanceDomain
Agent (Yang)Sprout GeneratorCreates venture structure
Agent (Yang)Venture BootstrapSelf-creates venture row + registers agent card
Agent (Yang)Engineering TeamRuns generator, validates output
Instrument (Yin)Acceptance TestVerifies 7-line contract
Instrument (Yin)Agent CardIdentity verification for mycelium discovery
Instrument (Yin)WorkChart SeedMeasures venture-scoped execution
Instrument (Yin)Cold Boot TestValidates "serves a request" not "compiles"

Key Design Principles

P&ID ElementA&ID EquivalentApplication
ProcessSprout GeneratorThe agent that applies force to create structure
InstrumentAcceptance TestThe instrument that verifies the process worked
PipelineBoot SequenceThe protocol connecting generator → bootstrap → instruments
Control LoopLegacy PrincipleTemplate improves after each run — the generator IS continuous improvement

Key Finding

The acceptance test is the single instrument that validates the entire pipeline. Seven binary measurements — no partial credit. This is the P&ID equivalent of a commissioning test on a new process line: every sensor reads, every valve opens, every flow confirms before the line goes live.
