The loop restarts you for the next bead. + +## Authoritative sources (read before coding) + +- **Plan — the source of truth:** `/home/coding/pdftract/docs/plan/plan.md` + (~3,825 lines, schema_version 1.0). Every bead description references plan line + ranges. Read the referenced section before you write code. If the code contradicts + the plan, the code is wrong. +- **Repo conventions:** `/home/coding/pdftract/CLAUDE.md` — this workspace uses + **`bf`** (bead-forge), not stock `br`.
