Stage-Gate Kanban Workflows and Deterministic Sprint Refits

Managing complex solopreneur infrastructure requires rigid stage-gate enforcement rather than endless, ambiguous task boards. Transitioning work items across explicit cryptographic state gates prevents premature merging and technical debt accumulation.

Stage-Gate Invariants

  1. Explicit State Boundaries: Tickets cannot transition from review to published without passing automated validation scripts and syntax lint checks.
  2. Immutable Audit Trails: Every Kanban state change appends an immutable JSON log entry to the local telemetry bus.
  3. Frictionless Rollbacks: Failed deployments automatically trigger reversion scripts, returning the workspace to the last known green commit.

Deterministic sprint refits eliminate administrative overhead and keep focus locked on functional delivery.
