Events & Scheduled Messages

Lets Synth schedule things for the future. She can register an event to act on at a given date/time, or queue a delayed message. A scheduler fires due events back into the message chain, and upcoming events are injected into the prompt context so Synth stays aware of what’s coming.

Backed by the scheduled_events table.

How the block reaches the model

static_inject contributes the upcoming_events block (“upcoming events (next N days) (informational only, do not act unless relevant)”) for the configured lookahead window, and the core renderer prints it under an [Upcoming events] heading on the ordinary chat and beat prompts (_PLUGIN_CONTEXT_BLOCKS in core/prompt_engine.py). The block was built on every turn and dropped until it was declared there, so this is the first time it reaches the model; the plugin’s own scheduling and firing path is unaffected. Vessel turns deliberately drop it (core/prompt_engine.py::_compact_prompt_for_vessel).
