+STATUSLINE INTEGRATION                                        *cp-statusline*
+
+cp.nvim exposes its runtime state through a public module that can be queried
+from any statusline plugin. Import it with: >lua
+    local state = require('cp.state')
+<
+All getters return nil when no problem is active, so guard every value before
+use. Calling any getter outside a CP context is safe and has no side effects.

+The following getters are available for statusline use:
+
+    get_platform()      (string?) Platform id. e.g. "codeforces", "atcoder"
+    get_contest_id()    (string?) Contest id. e.g. "1933", "abc324"
+    get_problem_id()    (string?) Problem id. e.g. "A", "B"
+    get_language()      (string?) Language id. e.g. "cpp", "python"
+    get_base_name()     (string?) Derived filename stem. e.g. "1933a"
+    get_source_file()   (string?) Full source filename. e.g. "1933a.cc"
+    get_active_panel()  (string?) Non-nil when the test panel is open.
