[Whamp]

Summary

• preserve the locked Combined System Prompt / Combined Tool Definitions taxonomy in project domain and decision docs
• check in the missing taxonomy plan, Pi 0.80.5 source research, extension-analysis decision, and issue Tool Envelope Overhead placement #19 prototype
• reconcile the early artifacts with final Wayfinder decisions for prompt-boundary overhead, non-counted extension additions, Source Trace placement, inactive tool grouping, and honest source attribution
• replace local installation citations with commit-addressed primary-source links

Validation

• pnpm run check — 30 test files, 206 tests
• 51 Markdown HTTP links returned 200; all relative links resolved
• Chromium exercised all three prototype variants, invalid-query fallback, pressed-button state, arithmetic reconciliation, and desktop/mobile layouts
• no browser console errors or horizontal overflow at a 305px content viewport
• fresh closure review: no findings

Scope

This publishes the decision corpus referenced by Wayfinder map #9. It does not implement or close the Combined taxonomy redesign.
