You push a new feature. It works in staging. You roll it out. Production blows up at 2 a.m. The logs trace back to a mismatch in user-defined settings — something your ramps were never meant to handle, yet everything depends on them. That is the hidden truth of ramp contracts: they are only as safe as the user config they assume.
A ramp contract maps changes to a controlled rollout. It guards against sudden failures. But if a user config changes underneath — a flag flips, a value disappears, a feature dependency shifts — the ramp loses its stability. Your safety net now pushes broken behavior to a wider audience.
The core problem is dependency coupling. A ramp’s contract assumes an environment. That environment is shaped by user config. When that config changes, the contract can violate its own guarantees. Most systems don’t bind configurations to contract state. That means every ramp is vulnerable to silent misalignments.
Solving this means making ramps user config dependent in a deliberate, explicit way. The ramp contract must lock against the exact configuration state it was tested with. If the config changes, the system must pause or revalidate the rollout. It’s not optional. It’s the only way to preserve the trust ramps are meant to create.
