Changelog

A summary of the capabilities that have shipped, grouped by area.

Trust center

Public marketing, docs, and a trust API
  • New

    Security & trust center

    A public page documenting deterministic verification, code-enforced provenance, RBAC, and the tamper-evident audit trail.

  • New

    Public trust summary API

    GET /api/trust/summary returns a high-level capability list and build info with no tenant data and no auth required.

  • New

    Product, pricing, and docs pages

    Static public pages describing what PaperTrail does, how it is priced, and where to find documentation.

Verification core

The claim-to-source verification pipeline
  • New

    Three-stage pipeline

    Retrieval, extraction, and verification agents run in sequence, each caching its work so shared sources are never recomputed.

  • Improved

    Deterministic effect-size cross-check

    The model's verdict is paired with a code-level check over parsed estimates and confidence intervals, so results cannot wobble between runs.

  • Security

    Grounding invariant

    Flagged spans that cannot be located in the cached source text are dropped, enforced in code and covered by tests.

Platform

Multi-tenant access and accountability
  • Security

    Role-based access control

    Owner, admin, editor, and viewer roles gate every authenticated route, with org-scoped data access throughout.

  • Security

    Tamper-evident audit trail

    Mutations write to an append-only, hash-chained audit ledger so past events cannot be silently altered.
