Glossary

Agent​

The model-backed worker that inspects, drafts, runs tools, and submits intended actions to FST.

Artifact​

A typed record that may satisfy a process requirement when its schema, provenance, run binding, profile version, and validation status are correct.

Approval Gate​

A gate that requires trusted human authority before a risky action or authority increase may proceed.

Approval Record​

A trusted record that grants or denies a specific approval scope. Agents may not create approval records through ordinary chat.

FST Authority Layer​

The part of FST that owns official process decisions: route selection, evidence admission, approval acceptance, scope grants, protected-effect preflight, and replayable decision records. Public components interact with it through contracts, not internals.

Decision Gate​

A gate for missing facts, branching, classification, hard rules, or ambiguity.

Evidence​

Structured records used to explain and replay route decisions. Evidence is not the agent's final summary.

Hook​

Process-owned logic called by FST to compute facts, validate artifacts, or render templates. Hooks cannot return routes, approvals, publication, or materialization authority.

LocalFile Store​

The transparent local store component that keeps FST records in inspectable workspace files.

Materialization​

The controlled effect outside FST, such as writing a review packet, creating a package, marking a patch ready, or later calling a protected connector.

Process Pack​

A directory or archive containing a process manifest, profile, optional hooks, schemas, scenarios, templates, and skill instructions.

Process Profile​

The versioned control contract for one workflow: actions, artifacts, gates, routes, approvals, scenarios, materialization rules, and report shape.

Process-Conformance Gate​

A gate that requires valid artifacts before the run can advance.

Replay​

Inspection of stored run state and evidence to explain why FST returned a route.

Route​

The fixed result vocabulary returned by FST:

Continue
InstructAgent
AskUser
AwaitApproval
Blocked
MaterializeMock
MaterializeAllowed
Complete

Run​

One controlled execution bound to a profile id, version, hash, actor, route history, artifacts, and evidence refs.

Scenario​

A test fixture that submits actions and expected routes against a profile. Scenarios prove that process behavior matches intent.

SQLite Store​

The single-file local database store component for the local product path.

Workspace​

The local directory initialized by FST. It contains .fst/config.yaml, state, installed process metadata, evidence, trace records, and store data.
