+# The Validator
+
+> **[INCOMING — Mission Control, Earth]**
+>
+> Cadet, every system that takes user input has to *validate* it.
+>
+> Comparison operators (`>=`, `<`, `==`) return `True` or `False`
+> directly. String methods like `.isupper()` and `.isdigit()` also
+> return booleans:
+>
+> ```python
+> len("hello") >= 8       # False
+> "Hello"[0].isupper()    # True
+> "abc1"[-1].isdigit()    # True
+> ```
+>
+> Implement `validate(pw)` that returns a dict with four checks on
+> a non-empty password:
+>
+> - `length` — char count (int)
+> - `long_enough` — `length >= 8` (bool)
+> - `starts_capital` — first char uppercase (bool)
+> - `ends_digit` — last char a digit (bool)
+>
+> [END TRANSMISSION]
+
+## Your Task
+
+In `starter/starter.py`, return the dict using `len()`, `>=`,
+`.isupper()`, `.isdigit()`.
+
+## Objectives
+
+- All four keys present with correct types
+- `validate("Andromeda1")` matches the expected dict exactly
+- Works for any non-empty password
