Data Model

Paseo uses file-based JSON persistence instead of a traditional database. All data is validated at runtime with Zod schemas. Most stores write atomically (write to temp file, then rename); a few still use plain writeFile — see each section. There is no schema-versioning/migration framework — schemas rely on optional fields with defaults for forward compatibility, with a small amount of inline normalization in persisted-config.ts for legacy provider/speech entries.

All server-side stores live under $PASEO_HOME (defaults to ~/.paseo).

The agents/{sanitized-cwd}/ directory name is derived from the agent's cwd by stripping the filesystem root and replacing path separators with - (Windows drive letters become a C- style prefix). Atomic writes (temp file + rename): agent records, chat, project/workspace registries, push tokens. Non-atomic (plain writeFile): config.json, schedules/*.json, loops/loops.json, server-id, daemon-keypair.json.

3. Local Speech Runtime

Path: $PASEO_HOME/runtime/local-speech/node_modules/

Native local voice packages are installed on demand at daemon bootstrap, not bundled with the daemon package. The runtime installer downloads npm tarballs into $PASEO_HOME/runtime/local-speech/.downloads, extracts them into a temporary directory, verifies required files, then atomically moves each package into node_modules.

Installed packages:

• sherpa-onnx
• sherpa-onnx-node
• sherpa-onnx-<platform>-<arch> for the current host
• onnxruntime-common
• onnxruntime-node

The daemon starts without waiting for these packages. While they are missing, server_info.capabilities.voice.* reports local voice unavailable through the existing capability fields. Once the runtime and required local speech models are present, the next speech runtime reconcile makes local voice available without restarting the daemon.

---

Active git projects are unique by normalized rootPath. Startup reconciliation repairs older bad states by moving workspaces from duplicate path-keyed projects onto the canonical project, preferring remote-keyed project IDs such as remote:github.com/owner/repo, then archiving the emptied duplicate.

---

10. Daemon meta files

These small files are not validated as full Zod schemas but are persisted under $PASEO_HOME for daemon identity and runtime coordination.

Path	Format	Notes
server-id	Plain text, e.g. srv_<base64url>	Stable per-$PASEO_HOME daemon ID. Overridable via PASEO_SERVER_ID env.

paseo.pid	JSON { pid, startedAt, ... }	PID lock; prevents two daemons sharing one $PASEO_HOME.
daemon.log	Pino log output	Default location; path/rotation configurable via log.file in config.json.

---

Client-side stores (App)

These live in React Native AsyncStorage or browser IndexedDB, not on the daemon filesystem.

AsyncStorage key: paseo-drafts (version 2)

{
  drafts: Record<draftKey, {
    input: { text: string, images: AttachmentMetadata[] },
