The full-label width check hid current-line attribution when only part of the commit metadata fit. Render into the remaining cells without covering source text; preserve offscreen and no-space guards.
Diff and snapshot sources were excluded before scheduling, and the separate diff renderer never painted attribution. Capture per-side Git provenance, preserve private object stores for historical tabs, and reuse the current-line worker and cache.
Replace the 16 MiB comparison rejection with independent bounded per-side loading and frozen Working blobs. Bound diff computation, defer large inline highlighting, index source-row navigation, and expose actual load failures. Verified the real 52.3 MB parser through repository/session APIs and terminal rendering with EOF/start navigation.
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.
