Synaptic

Synaptic is a source-grounded code maintenance platform built around three connected systems: **API maintenance**, **repository memory**, and a persistent **knowledge graph**. Together they let an engineer or AI assistant understand what the code does, remember what has happened to it, and make bounded repairs without guessing.

1. API maintenance keeps external dependencies and SDKs safe to change. Dependency bots can tell you a new version exists; Synaptic inventories the APIs your code actually uses, detects source-grounded breaking changes, finds the affected call sites, plans a bounded repair in an isolated worktree, verifies graph invariants and selected tests, and only publishes a draft PR when the evidence is complete.
2. Repository memory preserves the history that usually lives in people, chats, failed branches, incident notes, and old PRs. It records previous changes, regressions, decisions, procedures, verification results, and external artifacts as source-linked evidence, then retrieves that memory through the CLI or MCP server so future work starts with context instead of archaeology.
3. The knowledge graph is the structural map underneath everything. Synaptic turns any folder, monorepo, or federated set o
