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.
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.
Conflicted revisions read every file through jj file show, which returns
empty output for symlinks and causes repository-wide subprocess fanout.
Keep ordinary Git blob sources and immutable identities; render only
selected conflicted paths through jj.
Verified all 905 tests and the original local bookmark comparison with
25 correct paths in 0.522s, plus actual terminal conflict viewing.
Strict Clippy is blocked by existing diagnostics outside this change.
Word deletion reused cross-line word motion destinations. Constrain token traversal and boundary fallbacks to each caret’s current row while preserving cross-line navigation.
