Codeman/test/sensitive-path.test.ts

/**
 * @fileoverview The shared sensitive-path blocklist (`src/web/sensitive-path.ts`).
 *
 * This list guards every browser-facing file surface: workspace download,
 * cross-workspace attachment registration, raw/preview serving, and the
 * filesystem path picker.
 *
 * It became load-bearing when the picker gained `showHidden` (issue #221).
 * Before that, the picker refused any path with a dot-prefixed segment, so most
 * of the credential locations below were unreachable by construction and the
 * list only had to cover secrets that sit in plain sight. Opting into hidden
 * entries removes that accident, which is why each entry is pinned here: a
 * pattern silently dropped in a refactor would re-expose a real token.
 *
 * The list is a BLOCKLIST by design (cross-workspace attachment is a supported
 * feature), so the "stays attachable" cases matter just as much: over-blocking
 * breaks the publish skill and the review-card loop.
