Python/FastAPI appointment waitlist and cancellation workflow core
WaqtRelay is a locally runnable Python/FastAPI/SQLite software foundation for appointment cancellation recovery and opt-in waiting lists. It helps operators match available appointment slots with eligible requests, produce manual outreach drafts, accept provisional claims, and record approval only after verifying the original booking calendar. The buyer can inspect, develop and expand this technical foundation. The frozen v1.8.3 source includes setup documentation, synthetic demos, architecture notes and review-only extension models for airline, hotel and car-rental inventory. The governed R184-R186 engineering evidence records 284 passing local tests and a 93-file SHA-256 integrity check. These are local engineering checks, not production certification. Stage: pre-revenue, USD 0 MRR, zero verified paying customers. Local MVP; production deployment remains on hold. No actual provider integration, payment or official messaging integration, filed/granted patent, or established global market valuation. The public static preview represents an older synthetic release and is not a live v1.8.3 backend. Asking price: USD 2,000 gross for a one-time exclusive sale of verified seller-owned, legally transferable original software assets. Included after approved closing: agreed original source, tests, synthetic demos, documentation and extension specifications. Third-party components remain under their own licenses. Some code was developed with AI assistance. No guaranteed trademark, domain, customer list, external accounts, third-party copyright ownership, revenue or savings is included. Seller and buyer must complete title and license diligence, agree the scope and a written founder-approved contract, validate lawful payment/escrow and settlement, and confirm checksum-based acceptance before private-source handover. Support, fees, taxes and warranties require explicit agreement. Buyer-safe documentation is available through platform messages; no private source is published.
Next step: <p>A buyer can independently run the tests, review dependencies and title, then plan production security, identity and tenant isolation, durable operations, a commercial user interface and authenticated calendar/provider integrations. Airline, hotel and car-rental examples are review-only extension prototypes. Further engineering and provider agreements are required; no future revenue, deployment timeline or technical outcome is guaranteed.</p>
