GET /playthroughs/:id/phone returns the directory of the phone node the current node is wired to; POST /playthroughs/:id/dial resolves a number to connect (advance to the wired dialogue), voicemail (known contact, no line here), or not-in-service. Barricelli's note-board is wired to the phone node and Glitch Hunter's decline returns to it. Frontend (inventory on the board) is 2b. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
