SYSTEM STUDY / COLLECTION 01
UNDERSTAND
Open the machine. Read the layers. See what is actually there.
Four local-first tools for turning opaque systems into readable ones: repository structure, personal files, database internals, and evidence-backed retrieval.
BLACKBOX
See what a codebase is really made of.
BLACKBOX scans a local repository and surfaces structure, language mix, hotspots, dependencies, TODO/FIXME signals, suspicious patterns, and exportable JSON.
- Repository structure and language mix
- Hotspots, large files and suspicious patterns
- Dependency and Git signals
- Local-only scanning
Needle
Find what already exists on your machine.
Needle builds a lightweight local index over folders you choose, then lets you search, browse, open, and reveal files without sending filenames or content to a hosted search service.
- Build and update local indexes
- Fast filename and path retrieval
- Browse by extension
- Open or reveal results directly
PalisadeDB
A database from first principles.
PalisadeDB exposes the mechanics normally hidden behind a database API: pages, B+ trees, transactions, SQL parsing, persistence, and recovery.
- Custom .pdb storage format
- Pager and B+ tree implementation
- SQL parsing and execution
- Recovery and integrity inspection

Witness
Answers you can inspect, challenge, and reproduce.
Witness is a local-first evidence and retrieval workbench that makes the hidden parts of RAG visible: what was retrieved, what supports an answer, what contradicts it, and whether the available evidence is actually sufficient.
- Sentence-level provenance and exact evidence spans
- Inspectable retrieval routes, ranking and sufficiency
- Contradiction and source-version awareness
- Repeatable RAG Lab and adversarial Attack evaluation
