Glossary

Learning lab

A free study site. It is not a job claim and it sells nothing.

Artifact

A file the run wrote, so the result is not only a memory.

Pure function

Same input, same output, no hidden write.

Status code

The number HTTP uses to say how the request finished.

Secret

A value that grants access. It is not lesson content.

Golden set

Questions with agreed answers, reused so scores compare.

Token

The piece of text a given model reads or emits.

Grounding

Tying a claim to a passage you can open.

Context window

The maximum text one model call considers.

Temperature

A sampling control. It is not a truth dial.

Refusal

Stopping instead of filling a gap with a guess.

Model card

The provider's note of intended use and limits. Confirm it is current.

Done check

The condition that says the output is finished enough.

Role

The label that says whether a line is an instruction, a person, or a tool.

Schema

The declared shape of an output or a tool argument.

Regression

A check that used to pass and now fails.

p95

A point on the slow tail: about 95 of 100 samples are faster.

Diff

The lines that changed between two versions.

Passage

A chunk of source text the answer may use.

Chunk

The unit you index and later paste into a call.

Embedding

A numeric vector standing in for a piece of text.

Candidate

A passage the search thought might help. It is not yet the answer.

Citation

A pointer to a passage you actually retrieved.

Ablation

Turning one piece off to see what changes.

Workflow

Steps in an order you wrote down.

Tool

A function the loop may call, with a schema and a known effect.

Trace

The ordered record of what the loop did.

Approval

A recorded human decision before an undo-hard action.

ReAct

A pattern that writes a reason and takes an action in turns.

Simplest design

The fewest moving parts that meet the done check.

MCP

Model Context Protocol, a public way for hosts to use tool servers.

Host

The application a person is actually using.

Resource

Data a server can expose without necessarily changing the outside world.

Transport

How the bytes of the protocol move.

Root

A boundary on files or data a server may see. Confirm the spec's word.

Paper server

A design you can trace without running a public service.

Channel

A way a person and the assistant exchange a turn: voice, chat, or message.

Barge-in

The person starts speaking while the assistant is still talking.

SLA

A service promise. This lab does not state one.

Wording

The channel-specific sentence. The policy stays put.

Handoff packet

The note a person needs in order to continue without guessing.

Learning lab

Study material. Not a job claim and not a product.

Serving

Answering calls with a model that is already trained.

Confirm before relying

The mark this lab uses when a public figure was not re-checked today.

Endpoint

The address of a hosted model API. Confirm it before you call it.

Allowed corpus

Text you have a right to put in the lab.

Policy page

The short rules the capstone is graded against.

Portfolio

The files a later reader can check. Not a title.

Cascaded pipeline

Speech-to-text, a language model, and text-to-speech, in that order, as LiveKit's pipeline page describes it.

Barge-in

The person speaks while the assistant is still talking. Vendors name the detector differently.

Labeled latency

A timing sentence copied with the vendor's name. Not a promise from this lab.

Signaling

How the ends find each other. WebRTC's Wikipedia page says the media API does not include it.

Orchestrator

The framework that orders the stages. It is not itself the language model.

Ephemeral token

The Speech to Speech page's client-side credential, so the API key stays off the browser.

Transcript

Text from speech. It still needs a check against audio you are allowed to hear.

Polarity

A positive, negative, or neutral class. Wikipedia lists it as a basic sentiment task.

Rubric

The written behavior a score is about. Without it, the number has no meaning in this lab.

Redaction

Removing or masking information that can identify a person. A name-only pass can leave a linked identifier.

Pitfall

A failure mode named by a source. It is not solved by a fluent sentence.

Handoff packet

Channel, what was said, the note id, and the open question.

Guardrail

A check you can fail: schema, cap, and a person for an action that is hard to undo.

One-party exception

The federal condition in § 2511(2)(d) as copied by Cornell. It is not a map of state law.

Scripted test

Lines you wrote, with an expected property, saved next to the result.

Not a claim

A sentence this chapter refuses: legal advice, a sufficient guardrail, or a job title.

Sister system

A system beside the call. It is not the voice model.

Mind map

A learning picture of the person, the channels, and the systems beside the call.

Dispatchable location

The FCC page's phrase: a validated street address plus further detail such as a suite or apartment.

Integration map

Named arrows between systems. An arrow is not a deployment.

Bridge

A sentence that names two boxes and the direction between them.

Future hook

A dated note of what to re-check. Not a roadmap this site promises.
