**PROMPT FOR LLM (copy+paste below, then append your plan)**

You are converting a **generic plan of action** into a **production-ready research/engineering `todo.md`** that is directly executable by a capable coding agent. Your output must be a single Markdown document with a fenced **XML `<workflows>`** block. Do **not** include any extra commentary, explanations, or chat—**output only the document**.

### Transformation requirements

* Be **specific** and **operational**. Replace vague goals with concrete steps, commands, checklists, acceptance gates, and explicit assumptions.
* Prefer **compact, high-signal prose**. No filler. Use short paragraphs and terse bullets.
* If information is missing, make **minimal, clearly labeled assumptions** (e.g., “Assumption: …”). Do **not** ask questions.
* Compile the spec into **executable oracles**: pre/postconditions, invariants, consumer/provider API contracts, and **metamorphic properties**. Generate both tests and **runtime guards**.
