Context: Contract start date, end date, total duration, and any key milestones or phases mentioned. Return null if not stated.

The contract timeline includes the following explicitly stated elements:

• Contract Start Date (TO - Day of contract conclusion): The framework schedule assumes the contract conclusion date (TO) will be no later than December 31, 2026. If the agreement is concluded after this date, the Contractor must present an updated detailed schedule during Stage I.
• Contract End Date / Final Acceptance: The Final Acceptance of the entire order (Odbiór Końcowy) must take place no later than December 15, 2028.
• Total Duration: The total duration is not explicitly stated as a single value (e.g., in months or years) but can be inferred from the start and end dates and the durations of individual stages.
• Key Milestones and Phases: The project is structured into several phases with the following approximate durations and deadlines:
• Stage I - Pre-implementation analysis and Solution Project: Up to 12 weeks from the contract conclusion date (TO). A detailed schedule will be developed during this stage and submitted for acceptance within 20 working days from the contract conclusion date.
• Stage II - Environment preparation and basic installation: Up to 2 weeks after the completion of Stage I.
• Stage III - System creation/configuration, integration, and iterative work on test data: Up to 46 weeks after the completion of Stage I.
• Stage IV - Formal Test Migration, validation of migration tools, and report on readiness for production migration: Up to 12 weeks after the completion of Stage III.
• Stage Va - Security tests + corrections: Deadline is July 31, 2028.
• Stage Vb - Performance tests + corrections: Deadline is August 31, 2028.
• Stage Vc - UX research/tests + final acceptance closure: Deadline is September 30, 2028.
• Stage VI - Production Migration, Production Start, and training: Scheduled for October-November 2028. Publication of resources must be confirmed no later than November 30, 2028.
• Stage VII - Integration with KRONIK@ and data transfer + Final Acceptance: Scheduled for December 2028. The migration/integration with KRONIK@ and the Final Acceptance must occur no later than December 15, 2028.
• Stage VIII - Quality Guarantee: 24 months from the date of signing the Final Acceptance Protocol (Stage VII).

The provided schedule is a framework, and a detailed schedule for the project, including a detailed breakdown of Stage III into sub-stages, milestones, partial products, and their acceptance dates, will be developed by the Contractor during Stage I and will be subject to the Employer's acceptance.
