Add clipboard_formats: classify + diff the clipboard's available formats#403
Merged
Conversation
The clipboard holds the same content in several formats at once, and nothing reported which formats were present or detected when that set changed. Add classify_format/classify_formats (map standard CF_* ids + registered names to friendly categories), diff_formats (pure monitor primitive returning added/removed/changed), and a Win32 EnumClipboardFormats enumeration. Classifier and diff are pure and headless-tested; only the live enumeration is Win32.

Why
The clipboard usually holds the same content in several formats at once — a Word copy offers
CF_UNICODETEXT+HTML Format+Rich Text Format, a file copy offersCF_HDROP, a screenshot offersCF_DIB. Nothing reported which formats are present (so an automation could know what it can paste) or detected when that set changed.clipboard_formatsadds:classify_format/classify_formats— map standardCF_*ids and registered format names to friendly categories (text / image / files / html / rtf / csv / audio / …)diff_formats— a pure monitor primitive:{added, removed, changed}between two snapshotslist_clipboard_formats/clipboard_formats— enumerate the live clipboard (EnumClipboardFormats) without consuming anything, and classify itDesign
nametakes priority over the id since registered formats have dynamic ids (>= 0xC000). Descriptors accept an id,{id, name}, or(id, name).smart_waits.wait_until_clipboard_changes(which monitors content) — this reports the format set.RuntimeErrorelsewhere).__all__→AC_clipboard_formats(live) +AC_classify_formats/AC_diff_formats(pure) → read-onlyac_*MCP tools → Script Builder (Data).

test/unit_test/headless/test_clipboard_formats_batch.py— standard-id and named classification (name priority), summary categories/flags, diff added/removed/no-change, tuple descriptors, the pure executor paths (_classify_formats/_diff_formats), and 5-layer wiring. 25 passed alongside the clipboard siblings. Win32 enumeration not executed in CI.
