unleak-abstraction

Use when an abstraction leak must be sealed as a module seam, configuration option, or explicit override, or exposed as a named boundary. Not for detecting concealment patterns: use no-hide.

# Unleak abstraction

## Contract

| Field | Bound contract |
|---|---|
| Trigger | User names an abstraction leak and wants it sealed as a module seam, configuration option, or explicit override, or deliberately exposed as a named boundary. |
| Authority | Reversible local: writes only named local artifacts; rollback is stated before mutating (version control or undo). No remote mutation. |
| Side effect | Refactored code that seals or deliberately exposes the named leak. A wrapper is rejected if it adds more than half the measured complexity of what it hides. |
| Done | The abstraction leak is sealed or deliberately exposed; the complexity gate holds (wrapper complexity is less than half the hidden complexity, or both are zero as the zero-complexity case from step 5), confirmed by post-change re-measurement. |
