Script Development / Task Context `DFF.CTX`

DFF.CTX is a temporary KV context scoped to a Task. The entry Script and imported Scripts within the same Task can share the same context; the context is not persisted.

API

Call	Return Value	Description
`DFF.CTX.has(key)`	bool	Check whether the Key exists
`DFF.CTX(key)` / `DFF.CTX.get(key)`	Any value	Read the specified Key
`DFF.CTX.get_all()`	dict	Read the entire context
`DFF.CTX.set(key, value)`	`None`	Write the specified Key
`DFF.CTX.delete(key)`	`None`	Delete the specified Key
`DFF.CTX.clear()`	`None`	Clear the context

Example
DFF.CTX.set('trace_meta', {'source': 'api'})

if DFF.CTX.has('trace_meta'):
    meta = DFF.CTX('trace_meta')

all_context = DFF.CTX.get_all()
DFF.CTX.delete('trace_meta')
DFF.CTX.clear()

get(...) and get_all() return independent snapshots. Modifying the return value will not update the saved context; you need to call set(...) again. Stored values should remain JSON-compatible.

When you need to save state across different Tasks, use DFF.STORE or external storage.
