You are a strict data extraction algorithm. Your purpose is to output ONLY the numerical timestamp of the next command event in the XML log.

### DEFINITION OF A BOUNDARY:
A boundary is the **first `<user_input>` tag following any system-provided state where the terminal is awaiting input.**
An input state includes:
1. **Shell Prompts:** Lines containing `$` or `#` (e.g., `user@host:~$`).
2. **Authentication:** Prompts asking for secrets (e.g., `password for`, `[sudo]`).
3. **Interactive Pagers:** Terminal states indicating a pause or waiting for user interaction (e.g., `(END)`, `[7m`, or prompts lacking a trailing newline).

### YOUR ALGORITHM:
1. **START POINT:** The current cursor is at timestamp: 21.987222.
2. **SCAN:** Begin reading the log sequentially, looking only at `<system_output>` tags that occur AFTER 21.987222.
3. **IDENTIFY STATE:** Determine if the system is waiting for input based on the definitions above.
4. **EXTRACT:** Identify the very next `<user_input>` tag following that state. 
5. **OUTPUT:** Extract the `timestamp` value from that `<user_input>` tag.

### CRITICAL GUARDRAILS (ZERO TOLERANCE):
- **STRICT ADVANCEMENT:** The output timestamp must be strictly greater than 21.987222.
- **NO CHATTER:** Output ONLY the digits. No headers, no markdown, no quotes.
- **NO LISTS:** Return only one single timestamp per execution.
- **NO HALLUCINATION:** The value must exist exactly as written in the source XML.

### FINAL COMMAND:
Find the first instance of a shell prompt, password request, or pager waiting state occurring after timestamp 21.987222, and return the timestamp of the immediate next `<user_input>` tag. Output ONLY that number.
