Convert the approved readable-codebase plan into the ticket protocol this
repo already uses for long arcs (docs/project/backlog/README.md, 75 work
packages driven to done through it).
Adds docs/project/readable-codebase/ with:
- README.md — the ledger: session protocol, GREEN definition, restart
recovery, the agent loop, and an Order table of 35 tickets with their
dependencies and status.
- PLAN.md — the design record, committed so the repository holds the
complete state. A fresh session needs nothing outside it.
Two properties make the arc restart-safe. Each ticket updates its own
Status line and its README row in the same commit as its code, so the
ledger and git log cannot desync. And the plan lives in the repository,
so recovery is three commands and needs no prior context.
Records one correction found while scaffolding: the 22 abandoned agent
checkouts under .claude/worktrees/ are live registered git worktrees, not
orphaned directories. RD-15 must use `git worktree remove` and verify each
branch tip is an ancestor of main first. Spot-checked four; all are
already merged via 637d500.
