/**
 * Tests for .claude/helpers/statusline.js
 *
 * statusline.js has no exports (only a main block), so all tests run it as a
 * subprocess and inspect stdout. The --json flag makes output machine-readable.
 *
 * Run: node --test tests/helpers/statusline.test.js
 *
 * Coverage gaps addressed:
 *  - generateJSON: all required top-level keys present, valid lastUpdated date
 *  - performance targets included in JSON output
 *  - v3Progress thresholds: pattern count drives domainsCompleted (0→5)
 *  - security status: PENDING (no files), IN_PROGRESS (1-2), CLEAN (3+)
 *  - generateStatusline (default): non-empty, contains branding + sections
 *  - --compact flag: outputs minified JSON on one line
 *  - getUserInfo: git missing → defaults (name, modelName)
 *  - getLearningStats: no db → patterns/sessions/trajectories all 0
 *  - Script exits 0 in all modes
 *
 * NOTE: Functions that are not exported (getUserInfo, getLearningStats,
 * getV3Progress, getSecurityStatus, getSwarmStatus, progressBar) are verified
 * indirectly via the JSON output structure.
