# Headless Reverse Engineering

This context describes how users ask reproducible, read-only questions about
binaries through Ghidra without managing Ghidra's internal project model.

## Language

**Sample**:
An immutable sequence of input bytes identified by a cryptographic content
digest. Identical bytes are the same Sample even when they have different file
names or locations.
_Avoid_: Binary, file, target

**Analysis Profile**:
The declared analysis inputs other than the Sample, including the Ghidra
version, analyzer configuration, language selection, and tool protocol version.
_Avoid_: Configuration, settings

**Analysis**:
The reusable body of facts Ghidra derives from one Sample under one Analysis
Profile.
_Avoid_: Project, database, workspace

**Query**:
A read-only question evaluated against an Analysis. A Query cannot change the
Sample or Analysis.
_Avoid_: Command, job, operation

**Function Selector**:
An unambiguous reference used to choose a function by address or resolved
symbol name.
_Avoid_: Function name, function ID

**Artifact**:
A durable, schema-versioned representation of a Query result tied to its
Analysis.
_Avoid_: Output, report, result file

**Analysis Store**:
The tool-owned collection of reusable Analyses and Artifacts. It is disposable
and never contains the authoritative Sample.
_Avoid_: Project directory, cache directory, workspace
