//! Detect Copilot CLI through session-store.db assistant_usage_events columns.

// Transient antivirus/product locks cause Pending and retry on a later scan;

// do not persist them as UnknownFormat.

// If assistant_usage_events/required columns are absent, check the newer Copilot

// chronicle store verified locally on 2026-09-30 and in cli-config-dir-reference.

// The checked session-store.db is a checkpoint/search index;

// per-call usage moved elsewhere. Matching tables identify Copilot but lack verified per-call usage.

// Return UnsupportedVersion without fallback, rather than misidentifying it as unrelated SQLite.

// Matching columns use schema_version for V30 selection; native checked version=8.

// Registered versions use KnownVersion; absent/other versions try LatestFallback without claiming verified support.

/// Newer Copilot checkpoint/search schema requires all four tables:

/// sessions/turns/checkpoints/search_index. It distinguishes chronicle

/// (UnsupportedVersion) from unrelated databases (UnknownFormat).

// Checked newer CLI layout: chronicle/search index, without assistant_usage_events.
