Documentation Gaps in behaviors.md

Daily Documentation Review 2026-05-12

Several implemented API endpoints are missing from docs/dev/behaviors.md:

1. Icon Upload and Management API (PR feat(icons): add PNG/SVG icon upload and management #201 merged) - HIGH - Entire feature undocumented (GET/POST /api/icons, PATCH/DELETE /api/icons/:id, GET /api/icons/:id/file)
2. Tile Zoom Update - MEDIUM - PATCH /api/files/:id/zoom undocumented
3. Font Delete - MEDIUM - DELETE /api/fonts/:id not in API-020
4. Missing Workspace Endpoints - MEDIUM - GET /api/workspaces/:id, GET /api/workspaces/current, POST /api/workspaces/:id/leave, GET /api/workspaces/archived
5. WS-002 Verification Command Mismatch - LOW - references test_list_members* instead of workspace list tests

This issue has significant overlap with #249, #251, and #258 — all reporting missing behaviors.md documentation. Suggest consolidating into a single tracking issue to avoid duplicated effort. Maintainers: please consider closing duplicates and keeping one canonical issue.
