occam-gitignoreDeterministic .gitignore generation

Same input, byte-identical output. Hash-verifiable. No network, no LLM at runtime.

Deterministic by contract

Every output carries a sha256 hash, a core version, and a rules-table version. Two runs on the same tree produce byte-identical output, enforced by tests.

Hexagonal architecture

The core is a pure function of (fingerprint, options, templates, rules). All I/O lives in adapters — CLI, HTTP, MCP — sharing the same generator.

Explainable output

Every rule carries provenance (template, mined, or user). Mined rules come from a documented, lift-based association pipeline.

Low latency

No filesystem walks, no LLMs at runtime. On the local benchmark corpus, generation runs in well under a millisecond per repo.

Measured quality

The benchmark reports recall, precision, F1, stability, and latency p50/p99. CI fails when any threshold regresses.

Three adapters, one core

CLI, FastAPI HTTP, and MCP server share a single deterministic generator. Bench and training are offline harnesses on top of the same core.
