# .memory — the project record

For whoever *continues building* Turbo JS. `docs/` is for whoever *uses* it; the two are kept apart.

| File | What it is | How it changes |
| --- | --- | --- |
| `summary.md` | A snapshot of the present: what this is, how to build and test it, the decisions in force, what is not yet established | Edited in place, only the parts a session verified; never regenerated |
| `history.md` | One dated entry per session: what was asked, what changed, why, what was rejected | Appended, never rewritten |
| `handoffs/YYYY-MM-DD-<slug>.md` | Where a session stopped: work in flight, next steps, traps | One per topic per day; never another session's |

Read all three before doing anything; `summary.md` first, then the tail of `history.md`, then the newest handoff.
