The label lag came from repeatedly projecting full viewports while walking backwards from the caret. Skip only candidates whose maximum possible source/wrap and label height cannot reach the target, then retain the original first-target search. Reuse already resolved scope contexts. The conservative bound preserves non-monotonic unified declaration visibility and independent sticky labels. Added regressions for split declaration-visibility ties and unified height changes; architecture updated. Verification: 10,176 differential projections matched; all 964 release tests pass; release binary built. Reduced repro p95: 3.9572ms -> 1.4467ms. Live 160x100 function-dense 360-key burst median catch-up: 22.895ms -> 9.611ms, with final cursor/viewport asserted. Full and no-dependency Clippy checks are blocked by existing repository warnings, including vendored Crossterm, blame, LSP, Markdown, syntax and existing TUI code. Temporary harnesses removed. No remote changes.
The visible declaration already provides scope context. Cache the actual
identifier point separately from the declaration extent/decorators and hide
labels when it is visible in that side of the projected viewport.
Refill reclaimed rows and anchor carets against the resulting layout.
Retain sticky context when the symbol scrolls or wraps out of view.
Verified: 951 tests passed, cargo build, and real PTY smoke for declaration
visibility/scroll restoration, wrapping, horizontal clipping, unified view,
and short horizontal-pane caret reflow.
Compare each side with its preceding source row within the same excerpt,
not the adjacent aligned pair: alignment holes must not restart labels.
Retain sticky context independently on each side, including leading holes.
Regression: merged Python insert/delete hunks emitted five labels instead
of one. Verify deduplication, folded excerpt restart, and sticky-gap context.
Verified: cargo test (950 passed), cargo build, and real PTY smoke covering
split/unified, wrap, sticky gaps, and a short horizontal pane source caret.
Show per-side Tree-sitter scope paths inline and as sticky continuation labels.
Keep presentation rows out of source coordinates, selections, and edits.
Verified: cargo test (949 passed), cargo build, and real PTY smoke covering
split/unified, wrapping, both split axes, sticky scrolling, live rename and undo.
Size exception: 549 implementation lines added plus deleted, excluding tests
and docs. Keep syntax extraction and coordinate-safe rendering together as one
working behavior.
Use Resolution and Other version borders, omit branch/path metadata,
and show unsaved output state only on the writable pane. Track native
explorer conflict C from authoritative jj state across draft/check/error
transitions and clear it only after confirmed resolution.
Focused resolver and save tests pass; live terminal labels and explorer
verified without saving the mock conflicts. Full library run: 795 pass,
one unrelated async plugin fixture_barrier startup failure.
Use the active DiffState, native FilePicker and existing diff input,
layout, focus, source navigation and scrolling paths for Resolution.
Delete separate resolver filtering, file-list rendering and scroll APIs.
Keep projections, source choices, History and guarded jj saves distinct.
Verify native parity for picker remaps, current-file selection, excerpt
initialization, folded search, wheel focus, layouts, buffer transitions
and per-file viewports. All 932 tests pass; actual terminal smoke covers
Space-e explorer, Down/Enter file selection and guarded confirmed save.
Clippy completes with existing warnings only.
Size exception: 1197 implementation added/deleted lines excluding tests
and docs; input routing, native buffer lifecycle and rendering are kept
as one coherent cutover, without a parallel legacy resolver path.
Replace the marker-filled three-pane resolver with a marker-free native
Draft versus frozen Alternative projected from current working text.
Preserve preexisting outside edits, native undo, dirty-save guards, all
sides/bases, and draft caret/viewports across separate History views.
Reuse DiffState alignment/highlighting/excerpts for Resolution and merge
its base-aligned rows for readonly three-way History. Hide explorer and
source-selector chrome by default.
Verified 926 tests plus actual terminal projection, History highlighting,
hunk choice, optional explorer, and guarded jj-confirmed save workflows.
Clippy completes with pre-existing warnings only. Smoke fixtures stay
unresolved in this ancestry; remove that ancestry before publication.
Size exception: approximately 1650 implementation added/deleted lines,
excluding tests/docs, kept coherent because native draft lifecycle and
aligned rendering must change together without parallel legacy modes.
