Follow the task and return only the requested answer, without explanation or Markdown fences. You will read a prefix of a small scope language. Every block, regardless of its kind, creates a local scope. Statements are processed once, from top to bottom. A let statement binds a variable in the current scope. The nearest still-open scope containing the variable determines its value. Bindings in closed scopes are no longer visible. A nop statement has no effect. The final probe marks the observation point. Open blocks at the end of this prefix are intentional. Do not complete or repair the program. Return only a JSON array of the names of still-open blocks, ordered from outermost to innermost. Do not include the implicit global scope. If no blocks remain open, return []. SYNTAX The kind keywords are nezu for unit, sapu for func, and jomi for area. Each creates a local scope. Open a block with KIND NAME on one line. Close the innermost open block with wor KIND NAME on one line. KIND and NAME must repeat that block's opening keyword and name. KIND is one of nezu, sapu, jomi; NAME is n_ followed by exactly eight lowercase letters and is unique in the program. A binding statement (let) is fal VARIABLE VALUE. VARIABLE is x_ followed by one letter a through f; VALUE is a four digit integer from 1000 through 9999. Within one scope a variable is bound at most once. Inner bindings hide outer bindings until their scope closes. A no-effect statement (nop) is kiv PAYLOAD. PAYLOAD is p_ followed by eight lowercase letters. The observation marker is probe PROBE_ID VARIABLE. PROBE_ID is q_ followed by eight lowercase letters. Use one statement per line. Indentation has no meaning; scope is determined solely by explicit opening and closing lines.
