- Each tick: `local_snapshot` + `index_snapshot` → pure `reconcile()` → `Vec<Action>`
{Import, WriteFile, DeleteLocal, Tombstone, Merge} → execute → settle into `SyncState`
(atomic temp+rename to `data_dir/state.toml`).
- The `Wiremap` (ssync-core `wiremap.rs`) owns the adapters, the per-agent excludes, and
the path-map resolver: every wire-key ↔ local-path translation and every freeze verdict
(excluded key #14, dropped-agent guard, failed mapping #49) lives behind it — Engine
never touches adapters directly, and the freeze invariants are unit-tested there
without iroh.
- Import path: file → age-encrypt (subprocess) → `Node::publish` (blob + index entry keyed
`{agent}/{relative_path}`; the ONLY write path — temp-tag prevents the GC race).
- Export path: index entry → `Node::blob` (local miss → bounded fetch from peers behind
