Electron Ipc Reliability Governance

Apply a strict IPC workflow so request/response behavior remains predictable, cancellable, and backward-compatible.

Workflow

1. Map the IPC surface before editing:

• handlers in src/main/ipc/ipcRegisterHandlers.js
• exposed invokes in src/main/preload.js
• backend logic in src/main/ipc/*.js

2. Validate contracts first:

• check channel existence (invoke has ipcMain.handle)
• verify payload validation and required fields
• verify returned shape stays stable

3. Harden runtime behavior:

• ensure async handlers throw actionable errors
• ensure stream handlers send terminal states (complete/error/canceled)
• ensure cancel endpoints actually abort in-flight tasks

4. Keep compatibility:

• do not rename channels unless all callers are migrated
• keep optional fields optional and defaulted safely
