> Plain-language definitions of every term you'll see in arco, from match scores and flags to CV variants, Pipeline stages, and the Digest.

Terms you'll see in arco, in plain language.

**Board**

Your main screen. It shows current job matches ranked by score.

**Match score**

A 0–100 number representing how well a specific job fits you based on your profile and CV. For details on how it is calculated, see [How scoring works](/job-matches/how-scoring-works).

**Red flag**

Something in the job posting worth knowing before you apply: a requirement you don't meet, a vague description, or an unusual demand.

**Green flag**

A positive signal: strong alignment with your experience, or a benefit matching your stated preferences.

**Lane**

The broad category a company falls into (for example, Startup, Stable, or Innovation), shown as a coloured chip on each job card.

**Master CV**

The CV saved to your account, used to score every job. You can have one master CV at a time.

**CV variant / per-job CV**

A different CV used for one specific job inside the AI Coach, without replacing your master CV. See [Per-job CV variants](/ai-coach/per-job-cv-variants).

**Guided Optimization**

A three-step Coach flow (Audit, Fix, Verify) that improves your CV for one specific role. See [Guided Optimization](/ai-coach/guided-optimization).

**Pipeline**

Your application tracker, available as a Board (kanban) view and a List (spreadsheet) view.

**Stage**

Which pipeline column a job sits in: New, Saved, Applied, Interview, Offer, or Rejected.

**Status**

A more detailed progress field in Pipeline List view (for example, Phone screen, Final round, or Withdrawn). It sits alongside Stage.

**Find Jobs**

The button that manually triggers a fresh search. Availability depends on your plan. See [Refresh frequency](/job-matches/refresh-frequency).

**Digest**

A completed search run and the batch of matches it produced.
