Migrate Callers Then Delete Legacy APIs

Uni-pstack Runtime Adapter

This is a portable port of upstream Cursor pstack. Apply these overrides before following the original workflow:

• Cursor Task or subagent calls mean Codex delegation. In Codex, use native Codex subagents. In Claude Code, launch Codex CLI workers using the installed pstack skill spawn-codex-worker script or direct codex exec.
• Replace upstream Composer, Claude Opus, and other panel defaults with Codex gpt-5.6-sol and task-appropriate reasoning: medium for routine implementation and exploration; high for judgment, synthesis, and high-risk work. Use the supported fast or priority tier.
• Claude-only fallback model policy lives in the installed pstack delegation reference. Do not infer Claude model choices from this skill.
• Cursor-only commands such as loop, babysit, deslop, control-ui, and control-cli are conceptual cues. Use the host terminal, browser, review, subagent, and git tools directly.
• Cursor paths become host-appropriate project or user configuration paths. Preserve the workflow intent, not Cursor-specific storage.

When we decide a new API is the right design, migrate callers and remove the old API in the same refactor wave instead of preserving compatibility layers.

Rule:

• Do not keep legacy API paths alive only because internal callers still exist
• Inventory callers, migrate them, and delete the old API immediately
• Treat temporary adapters as exceptional and time-boxed, not default architecture
• Update tests to assert the new contract, and delete tests that only protect pre-refactor implementation details
