5. The Master Architecture (Tier 1: The Core Engine)

Objective: Master the 5 Core Tenses that handle 95% of all human communication. We are abandoning the 12-tense system to focus exclusively on the "High-Frequency Kernels."

Part 1: Standard Library Upgrade (The Corporate & Casual API)

Note: Memorize these as complete, unbreakable functional blocks.

The Block	The Logic	Execution
Wrap up	To finish or conclude a task/event.	"We wrapped up the meeting at 4 PM."
Look into	To investigate a problem or issue.	"The engineers are looking into the engine failure."
Rule out	To eliminate an option or possibility.	"The doctor has ruled out a viral infection."
Hand over	To give control or responsibility to someone else.	"I will hand over the keys to the next shift."

Part 2: Tier 1 (The 5-Core Logic Engine)

If you can execute these five logic loops perfectly, your English OS will never crash in a professional environment.

1. The Routine Loop (Present Simple)

Logic: Facts, habits, schedules, and permanent states.
Formula: [Subject] + [V1 / V5]
Trigger: Every day, usually, always, on Mondays.
Execution: "The cargo flight departs (V5) at midnight."

2. The History Log (Past Simple)

Logic: Finished actions with a specific time stamp. If you mention when it happened, you MUST use this.
Formula: [Subject] + [V2]
Trigger: Yesterday, in 2023, last week, two hours ago.
Execution: "The surgeon completed (V2) the operation yesterday."

3. The Future Projection (Future Simple)

Logic: Promises, sudden decisions, or predictions.
Formula: [Subject] + Will + [V1]
Trigger: Tomorrow, next year, soon, I promise, I think.
Execution: "I will hand over (V1) the project files tomorrow."

4. The Active Thread (Present Continuous)

Logic: Actions running exactly right now, or currently in progress this week.
Formula: [Subject] + Am/Is/Are + [V4 (-ing)]
Trigger: Right now, at the moment, currently, this week.
Execution: "The technicians are looking into (V4) the network outage right now."

5. The State Change / Result Log (Present Perfect)

Logic: An action happened in the past (time unknown or unimportant), and the result is visible now. (Never use "yesterday" with this!).
Formula: [Subject] + Have/Has + [V3]
Trigger: Already, just, recently, yet.
Execution: "We have ruled out (V3) a hardware failure." (Result: We know it's a software issue now).

Part 3: Debugging Gauntlet (30 Questions)

Instructions: Identify the "Time/Logic Trigger" in each sentence. Refactor the sentence into the correct Core Formula (Tier 1). Integrate the Standard Library API where requested. Write your clean code directly below each prompt.

30. (Integration): "Although he is working hard yesterday, he doesn't finished the task." (Fix the History Log and the Exception logic)

Clean Code: "The pilot landed the plane safely yesterday morning."
Logic: "Yesterday morning" triggers the History Log (Past Simple, V2).

Clean Code: "The nurse is checking the patient's blood pressure right now."
Logic: "Right now" triggers the Active Thread (Present Continuous, am/is/are + V4).

Clean Code: "We delivered the heavy machinery two hours ago."
Logic: "Two hours ago" is a specific past timestamp, requiring the History Log (V2), not the Present Perfect.
