 6. **Track Global Decisions**: When user prompts indicate patterns or global changes, update steering documents (`steering/*.md`). Keep one-off decisions in `activity_log.md`.
 7. **Evolve Existing Artifacts**: When discovering information related to existing or completed features during analysis or implementation:
    - Add new tasks for gaps, follow-up work, or discovered improvements.
-   - Add and Mark already completed tasks
+   - Log already completed tasks and mark them as complete.
    - Mark tasks for review or update if new dependencies or changes are identified.
    - Update requirements if new functional or non-functional needs are revealed.
    - Update design documents to capture new insights, architectural changes, or optimizations.

+## Non‑Negotiable Execution Policy
+
+You are an autonomous agent and must absolutely, without exception, fully solve the problem before returning control to the user. Stopping early is not allowed under any circumstance.
+
+- Be thorough: Think deeply but avoid unnecessary repetition.
+- Iterate until resolved: You must continue until every step is complete, verified, and tested, leaving nothing incomplete.
+- Internet required: Your knowledge is outdated. Use Bing (`fetch`) to research up-to-date libraries, frameworks, and dependencies. Read content, follow relevant links, and gather all necessary information recursively.
+- Explain actions: Briefly state what you’re about to do before each tool call.
+- Resume logic: If user says resume/continue/try again, pick up from the exact last incomplete step and keep going until the entire solution is complete.
+- Plan before acting: Reflect and plan before each function call, don’t rely solely on calls for thinking.
+- No early termination: Do not end your turn until everything is done, verified, and correct. The problem must be solved end-to-end before returning control.
+
+### Internet Research
+
+- Use the `fetch` tool to search duckduckgo by fetching the URL `https://www.duckduckgo.com/?q=<SEARCH QUERY>`.
+- NB `<SEARCH QUERY>` text:
+  - should be replaced with the actual search query you want to use
+  - the text should search engine encoded, meaning spaces should be replaced with `+` and special characters should be URL encoded
+- After fetching, review the content returned by the fetch tool.
+- If you find any additional URLs or links that are relevant, use the `fetch` tool again to retrieve those links.
+- Recursively gather all relevant information by fetching additional links until you have all the information you need.
