Script workflow extension
Keep workflow business logic in this packaged extension. Import only public
deerflow_extension_api contracts, standard library and declared QuickJS dependency;
never import private app.* or deerflow.* runtime modules.
Generated script runs only in worker.py's isolated, capability-free JS context. Never pass host callables, capability handles, credentials or ambient environment into it. Keep every IPC and stored/public payload bounded. Parent lifecycle must kill and reap the worker and explicitly observe child cancellation.
Persist stable child thread, input message, attempt and idempotency identity before admission. Workflow cancel is a supervisor signal; do not cancel an admission task and lose an already-created child. Timeout/unknown outcomes require reconciliation, never automatic retries. Distinguish admission uncertainty from post-admission observation timeout: interrupt/observe known runs and escalate only uncertain cleanup. Keep the workflow deadline handler outside asyncio.timeout and test external cancellation separately. Hash the Agent allowlist in canonical sorted order. Owner scope applies to every public read and mutation. Own persistence through supervisor publication even if the launching caller cancels. Serialize launch admission and shutdown. After artifact IO, validate call limits and step uniqueness together with await-free reservation. Hold the process lock across service life; do not recover live records while another Gateway owns the file.
Anchor results on the visible human input, including canonical __user rewrites; never use hidden system/memory IDs. Retain UI launch identity across refresh failures. Thread latest state is not immutable run output. Check message/run attribution, interrupts and pending human input before copying output. Agent success is never human approval. Live checkpoints retain the worker without replay; restart interrupts all waits. Bind human decisions to source output hash, step/attempt and authenticated session ActionContext, never ToolContext. Persist before waking; fence duplicate resume by checkpoint ID. Config revision is a declarative preflight guard. Store actual host assembly evidence per child run; never expose raw credentials. File checkpoints bind append-only captured bytes and SHA-256; preview and approved consumption read that exact version. Never claim hard currency limits or freeze external state. Do not serialize capability handles.
Tests live in backend/tests/test_workflow_plugin.py. Run the backend offline and blocking-I/O targets plus verify_browser.mjs. The browser fixture is loopback-only and synthetic; it must never become a deployed authentication bypass.
