Self-Evolve Loop

This skill learns across invocations — the full contract is SELF-EVOLVE.md. Start: read the learnings journal — ~/.ink-and-agency/learnings/accessibility-tester.md and/or the workspace-local .ink-and-agency/learnings/accessibility-tester.md — if present, and apply its guidance. End: self-evaluate the results; optionally ask the user for feedback (never block on it); append signal-bearing learnings to the journal (user-global when the sandbox allows writing there, workspace-local otherwise); route skill-improvement ideas per the contract's tiers — edit the canonical source when one is present, never the plugin cache.
