# Save Checkpoint. Route the stash. Update state. Generate projections. Keep working. Save is NOT a termination. The session continues. Save can happen multiple times. Each save increments the `saves:` counter and updates `last_saved:`. The stop hook only blocks when `saves: 0` (never saved). --- ## Flow ### 1. Read First (understand before acting) Read these in parallel before presenting the stash or writing anything: - `_kernel/now.json` — which bundle is active? What was the context? Which tasks are urgent or active? - `_kernel/log.md` — first ~100 lines (recent entries — what have previous sessions covered?) - Active bundle's `context.manifest.yaml` — if `now.json` reports an active bundle, read its manifest **Do NOT read per-bundle task files directly** — task data lives in `now.json` already (computed projection), or call `tasks.py list --walnut {path}` if you need specific detail. In v3, tasks are stored in `tasks.json` per walnut and per bundle, managed only through the supported task tooling (`alive tasks promote` for batched stash promotion in step 6c, `scripts/tasks.py` for direct edits like done / priority changes). Never edit `tasks.json` from the agent. **If `_kernel/now.json` does not exist:** suggest running `python3 "$ALIVE_PLUGIN_ROOT/scripts/project.py" --walnut {path}` to generate it. **Standalone session (no walnut loaded):** If no walnut was opened this session, the squirrel still has a stash to route. Ask: "Which walnut does this session belon...
