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.
