An expanded branch can look familiar while the editor is pointing at the wrong draft. A dependable writing restart uses three coordinates: the saved tree path, the open tab path, and an explicit next-action marker in the manuscript. For the query “text editor file tree resume writing,” this guide tests those coordinates with chapters/part-a/scene.md and the unique marker NEXT-351. It relies on stored paths and content, not a memory of how disclosure arrows looked yesterday.
Make a Restart Card Before Closing
Before ending a session, record the active file as a workspace-relative path. The controlled target here is chapters/part-a/scene.md. A basename such as scene.md is insufficient because another part or archived draft can use the same name. The test also retained one working tab that pointed to this exact path.
The second line of the file contained NEXT-351 followed by one specific editing action. This is production metadata, not prose for readers, so it belongs only in the working copy and must be removed before publication. Separating the test workspace from the release manuscript prevents the marker from leaking into an export.
Expand Only the Two Branches Needed Next
The saved test workspace listed two expanded folders: chapters and chapters/part-a. Opening every branch would make the tree noisy and weaken its value as a restart cue. Preserve the branch containing the active chapter and only the reference branch required for the next decision.
Expansion should communicate intent rather than merely preserve history. A branch opened during an unrelated search does not need to survive the session. Before closing, collapse incidental branches and keep only those that answer “where will I work next?” This small cleanup also makes an unexpected extra path easy to detect during the next comparison.
Write expected values before closing: two expanded paths, one tab, and one next-action marker. Expectations created after reopening merely describe whatever happened, including accidents. A fixed restart card lets the next operator compare observed state with an earlier decision.
Close, Reopen, and Read Three Coordinates
After the controlled workspace was closed and reopened, its saved record returned one tab and the two expected expanded paths. The tab path pointed to scene.md. A search of that file found one NEXT-351 occurrence on line two. All three coordinates converged on the same chapter, so the persisted restart state passed.
This measurement concerns workspace data and manuscript content. It did not inspect the graphical shape of a disclosure arrow after relaunch. The accurate statement is that two expanded-folder paths were read back from persistent state, not that every visual detail of the tree was observed.
Match the Complete Relative Path, Not the Tab Label
Names such as scene.md and chapter.md often repeat across parts. If the operator trusts only the visible tab label, an archived or translated copy can appear correct. Use the same complete relative path on the restart card, in the tab record, and in the tree record.
Check one piece of content as well. The marker in this test was unique and appeared on line two. Zero matches may mean an unsaved change was lost. Two matches make the marker ambiguous. In either case, do not start editing; identify the authoritative chapter and create a new, unique restart record.
Detect the Failure Where Only the Tree Returns
A branch can be restored while the selected tab points elsewhere. The reverse can also happen: the correct file opens, but an old next-action note no longer describes the intended work. Any mismatch among tree path, tab path, and marker makes the restart incomplete.
For recovery, place the stored expanded paths, tab path, and marker search result side by side. Compare them with the card captured at shutdown instead of guessing which file is newest. When needed, open candidates without editing and compare their relative path, first heading, and recorded update time.
If the restart card itself is missing, treat the session as an unverified recovery rather than inventing an expected state. Search for the unique marker across the workspace, inspect candidate paths, and save any uncertain version under a new name. Only after the authoritative source is identified should the operator create a fresh card and resume normal editing.
Test Disclosure Arrows as a Separate UI Question
Rune Studio’s public information describes writing organization through workspace trees and tabs. This controlled test read .rune-workspace values and manuscript text. It did not automatically measure the disclosure-arrow rendering, selected-row appearance, or scroll position after the app relaunched.
A visual test should capture before-and-after screenshots, application version, selected row, and scroll position. Keep that result as an interface observation rather than rewriting the stored-state result. If the persisted paths are correct but the display is wrong, separate records reveal where the defect belongs.
Remove or Renew the Marker After Resuming
Immediately before editing, read the restart card and the in-file action aloud and confirm that they describe the same task. When the action is completed, delete NEXT-351 or replace it with a new unique marker. Accumulated stale markers make the next search ambiguous and eventually turn a useful cue into clutter.
The handoff should report one tab, two expanded paths, one marker, the target path, and the marker’s line number. It should also state that disclosure-arrow appearance was unmeasured. A successful restart does not recreate a familiar-looking window; it reproduces the ability to begin the previously chosen action in the correct source file.
For long interruptions, add a short reason to the next-action marker: what decision was pending and which reference supports it. Avoid pasting a whole task list into the manuscript. One concrete action and one reference path are easier to validate, renew, and remove than an undated collection of intentions.
