Workflow Connector Hub

SOURCEREADME.mdAdapted for portfolio readability; claims remain source-derived.

A public-safe ASP.NET Core integration proof that receives synthetic requests, routes them through deterministic mock connectors, protects against duplicate execution, applies bounded retries, escalates unresolved work for human review, and preserves an audit trail.

**Status:** released at `v1.0.0` **Portfolio lane:** business systems, APIs, and workflow integration **Stack:** .NET 8, ASP.NET Core, C# **Data:** synthetic only

What it proves

request validation and correlation;
connector abstraction without fake production claims;
idempotency-key replay protection;
review-first routing for sensitive mock connector categories;
bounded retries and dead-letter escalation;
append-only submission, replay, and attempt evidence;
native API, responsive evidence UI, deterministic tests, and CI.

Native workflow

The running application exposes:

All connectors are local mocks. The project does not contain provider credentials and does not perform external writes.

Deliberate boundaries

no real connector credentials;
no live email, calendar, file, GitHub, or accounting write;
no uncontrolled retry loop;
no silent duplicate request creation;
no automatic approval of review or dead-letter records;
no client payloads or proprietary workflow rules;
no claim of production deployment.
