Verity v1.0.0: A data layer that enforces server-as-truth and eliminates optimistic updates
https://www.reddit.com/r/programming/comments/1oyv43v/verity_v100_a_data_layer_that_enforces/

<!-- SC_OFF -->I've been working on Verity, a framework-agnostic data layer that addresses a problem I kept running into: modern frontends blur server-owned truth-state with client-owned view-state, leading to optimistic updates, flicker, and user distrust. Core Philosophy: The server is the only source of truth Truth-state (server data) ≠ View-state (client UI concerns) Server emits directives describing what changed, not how to update the DOM Key Features: Directive-driven invalidation — server decides what needs refreshing Framework-agnostic core with adapters for Alpine, React, Vue, Svelte Multi-client synchronization via SSE Level conversion planning (derive "summary" from "full" without refetching) No optimistic updates — honest loading states instead Automatic coalescing, latest-wins guards, memory management Use Cases: Best for applications where server truth matters: real-time dashboards, multi-user tools, financial/healthcare/compliance systems, operational control rooms. Why not just use TanStack Query/Apollo? Those are excellent libraries, but they encourage optimistic updates and put invalidation logic in client code. Verity puts the server in control of the invalidation contract and refuses to lie to users about state. Examples included: The repo contains full-stack examples in multiple domains (invoice management, financial compliance, manufacturing monitoring, telehealth triage) with "baseline" versions that don't use Verity for direct comparison.
