STABILIZATION_SCOPE.md

Fontshow — Stabilization Phase Contract

Current version: v0.28.7.post14 Applies to: Phase 1 — Stabilization sprint


Purpose

This document defines the scope, rules, and acceptance criteria for the stabilization phase.

The stabilization phase exists to:

  • reduce friction,
  • formalize existing behavior,
  • and prepare the codebase for controlled evolution.

This document is normative for all stabilization work.


Definition of Stabilization

In Fontshow, stabilization means:

  • making existing behavior explicit and reliable,
  • removing ambiguity from contracts already relied upon,
  • improving robustness without expanding feature scope.

Stabilization is about correctness and clarity, not innovation.


In-Scope Work

The following types of work are explicitly allowed:

  • Documenting implicit behavioral contracts.
  • Fixing inconsistencies between code, tests, and documentation.
  • Improving error handling where behavior already exists.
  • Refactoring to make existing behavior reliable and testable.
  • Removing or reclassifying obsolete or misleading functionality.

Out-of-Scope Work

The following are explicitly not allowed during stabilization:

  • Introducing new user-facing features.
  • Expanding CLI command sets.
  • Changing output formats without backward-compatibility handling.
  • Large-scale architectural redesign.
  • Performance optimizations unrelated to correctness.

Any work that violates these constraints MUST be deferred.


Acceptance Criteria

Stabilization work is considered complete when:

  • All stabilization issues in the milestone are closed or explicitly deferred.
  • Documented behavior matches observed behavior.
  • Tests reflect documented contracts.
  • No “temporary” fixes remain undocumented.

Partial stabilization is not acceptable.
