1	# Automatic titles after outline movement
2
3	Three native pages distinguish vertical ordering, horizontal ordering and an
4	explicit title. Moving the second outline ahead of the first changes the two
5	automatic titles to `Second 🦋 é`; the explicit title remains unchanged.
6
7	`before` is the native source. `native` records the corresponding COM moves and
8	an independent cold reopen. `candidate` is the Rust edit; `cold` is its independent
9	OneNote reopen. Cold captures preserve exact active graphs. Rust movement retains
10	all text identities, content, formatting and history. Identical artifacts link
11	to one copy; `provenance.json` records the native runs and clone teardown.
12
13	The Rust regression originally left both automatic-title fields unchanged.
14	Position edits now update the existing page and metadata caches within the same
15	revision as the coordinates. The offline regression additionally changes the
16	remote title-producing text, loses the publication reply and reopens the cache
17	before confirmation and a dependent edit.
18
19	Run `tools.test_outline_edit.OutlineEditTest.test_automatic_titles_follow_native_and_rust_outline_movement`
20	through Python unittest after building the workspace examples with all features.
21	The Rust test `native_automatic_and_explicit_titles_follow_outline_movement` can
22	export a new candidate directory through `ONESTORE_OUTLINE_TITLE_OUTPUT`.
23
24	To regenerate the native controls, copy `fixture.json` and the synthetic section
25	from `corpus/native-delete/deletion-05/before` into a new input notebook directory.
26	Capture it with `tools/native_runner.py --author tools/native/pages.ps1
27	--collect-notebook`. Capture that result's notebook with
28	`--author tools/native/outline-title.ps1 --collect-notebook`, then independently
29	cold-open both the native result and the Rust candidate without an author script.
