synapbus/cmd/docgardener/main.go

// docgardener is the rich HTML report renderer for the doc-gardener
// example. It queries an existing SynapBus SQLite DB (the one that the
// docker-isolated agents wrote into) and produces a single-file HTML
// snapshot of the most recent goal: task tree, spawned agents, spend
// per billing code, trust deltas, and a timeline of events.
//
// The orchestration that USED to live in this binary (`docgardener
// agent` per-role subprocess entry, hardcoded task tree, gemini fall-
// back) has been replaced by the MCP-native flow at
// examples/doc-gardener/. All this binary does now is render reports.
