UX change:
- The "open Parallel Reader" command now toggles the right sidebar's
collapsed state instead of detaching the leaf. The tab and its content
are preserved across hide/show, matching standard Obsidian behaviour
for File Explorer and friends. Detaching the tab on every second
press destroyed cached cards and forced re-generation.
Behaviour:
- No leaf yet → create + reveal
- Leaf exists, right sidebar collapsed → reveal (expands sidebar)
- Leaf exists, right sidebar expanded → collapse(); tab is preserved
- No right sidebar (mobile / unusual layout) → reveal as fallback
Tests:
- New tests/view-render.test.js (18 cases) covering the component layer
that was previously a gap. The 1.0.12 → 1.0.13 sidebar regression
could not have been caught by any existing pure-function test; this
file fills that gap by mocking app.workspace + view spies and running
real runForFile / refreshViewAfterCache* / toggleParallelView.
- shouldRender matrix (4 cases): silentView × sourceFile state — the
exact regression introduced in PR2 where guards were over-applied.
- toggleParallelView (4 cases): no-leaf opens, expanded → collapse,
collapsed → reveal, no-rightSplit fallback.
- refreshViewAfterCacheDelete + Clear (4 cases): matching file vs
different file vs no-view, plus clear-all always renderEmpty.
- runForFile outcome enum mapping (6 cases): already-running early
return, already-running from catch, cancelled, generic error,
regenerate-confirm cancellation, skipEditConfirm bypass — these
drive batch statistics and were untested before.
- view.deleteCard / updateCard cardPersistFailed path (3 cases):
exposes ParallelReaderView via test-exports for instantiation;
mocks cacheReplaceCards returning false to verify the failure
notice path lands and the public method returns false.
src/test-exports.ts: export ParallelReaderView for component tests.
tests/catalog.json: register view-render.test.js under component.
