Vectorless RAG v0.3.0

Version 0.3.0 completes the first bounded PageIndex v2 evaluation and hardens the retrieval, accounting, and operator workflows it exercised.

Highlights

• Completed the reviewed 120-case PageIndex v2 evaluation as a 1,080-trial experiment, with recorded metrics, accounting evidence, exclusions, and immutable artifact identities.
• Kept the evidence budget unchanged because the experiment found no consistent quality gain from larger windows.
• Added resumable concurrent evaluation, claim-level judging, deterministic reporting, atomic cost reservations, experiment ownership, and interrupted-owner recovery.
• Hardened PageIndex parsing for control characters, pageless tables of contents, continuation entries, large nodes, and sparse terminal sections.
• Tightened evidence routing, metadata constraints, guarded catalog SQL, hybrid retrieval, and citation requirements.
• Added operator commands for environment reconciliation, index freezing, evaluation execution and recovery, claim review, query-cost reporting, and provider-free PageIndex patch checks.
• Reconciled Compose and Helm provider-pricing settings and aligned all release metadata at v0.3.0.

Release status

This remains a source-only research prerelease for bounded pilots. It does not claim production stability, unattended full-corpus ingestion, OCR support, or a final vector-versus-PageIndex quality verdict.

Vectorless RAG v0.2.0

0.2.0, 2026-07-27

Version 0.2.0 publishes the repository under the MIT License as a source-only research preview.

Added

• TanStack Start operator console for chat, documents, ingestion, settings, scoped connection, appearance, and logout
• Encrypted HttpOnly browser session backed by FastAPI API-key validation
• Durable PDF ingestion, PageIndex v2 artifacts, catalog routing, page citations, usage accounting, and provider-state handling
• Docker Compose and Helm deployment surfaces
• Deterministic API, PostgreSQL integration, browser, deployment, image, and evaluation checks
• Atomic local environment initialization and indexed public documentation

Research-preview limitations

• The default gate permits 25 registered documents and keeps full-corpus ingestion disabled
• The frozen pilot has a $10 provider-cost ceiling
• DeepSeek-backed ingestion and chat incur external provider cost
• Optical character recognition, API-key lifecycle management, and an embedded PDF viewer are unavailable
• Full 537-document ingestion and a final vector-versus-PageIndex quality verdict remain outside this release
• The release contains source archives only
