sigmap vs selvedge
sigmap: SigMap builds a deterministic, auditable signature-and-evidence map of your codebase without LLM calls or embeddings. It allows AI agents, CI, and reviewers to trust and verify code references, significantly reducing token usage and improving task success rates.; selvedge: Selvedge provides long-term memory for AI-coded codebases, capturing the 'why' behind agent-made changes directly from the agent's context. It acts as a local MCP server, logging structured events to a SQLite database, allowing developers to query the reasoning for code modifications years later.

Features
sigmap01Deterministic, Auditable, and Verifiable Code Mapping: Generates byte-stable code maps without LLM inference, ensuring consistent and trustworthy output for AI.
02Zero Dependencies and Offline Functionality: Runs locally with no external dependencies, vector databases, or hosted services, ensuring full privacy and offline use.
03AI Answer Grounding and Fabrication Detection (`sigmap verify`): Flags fabricated files, imports, and symbols in AI answers by tracing them to real line anchors in the codebase.
04Broad Language Support: Supports 35+ programming languages, including TypeScript, Python, Go, Rust, Java, and R.
05Model-Agnostic and Agent/IDE Integrations: Works with cloud LLMs (GPT-4, Claude), local LLMs (Ollama), open-source agents (Aider), and popular IDEs (VS Code, JetBrains, Neovim).
selvedge01Live capture of agent reasoning and intent directly from the agent's context.
02Tracks changes at an entity-level (e.g., DB columns, API routes, environment variables) rather than just lines of code.
03Stores all change events and reasoning locally in a durable, queryable SQLite database.
04Provides CLI tools for blaming, diffing, searching, and managing the history of AI-generated code changes.
05Exports and imports change history compatible with the open Agent Trace v0.1.0 standard.

Use Cases
sigmap↳Grounding AI agents with trustworthy, auditable code context to prevent hallucination and ensure factual accuracy.
↳Verifying AI-generated code, plans, and answers within CI/CD pipelines to maintain code quality and prevent errors.
↳Assisting code reviewers by flagging fabricated code references or inconsistencies in AI-assisted pull requests.
↳Providing rich, deterministic context for local LLMs and open-source agents, enhancing their performance without API costs or privacy concerns.
↳Scaffolding new code and directories based on established project conventions, ensuring consistency and adherence to architectural guidelines.
selvedge↳Understanding the historical 'why' behind schema decisions and migrations in long-term AI-coded projects.
↳Providing an audit trail for AI-generated code changes, essential for compliance (e.g., SOC 2, EU AI Act).
↳Helping solo developers recall the purpose of AI-generated code in their side projects or internal tools.
↳Enforcing checks for prior attempts on entities to prevent agents from re-introducing reverted decisions.
↳Tracking the full scope of a feature or task across multiple entities and commits using changesets.
