- Removed terminal risk mode toggles from config, terminal state collection, and render controllers.
- Dropped snapshot freezing, thaw tracking, and finalized-block replay in transcript rendering.
- Removed clear-on-shrink settings and initialization hooks from selector and interactive mode flows.
- Simplified render scheduling by using requestRender() without mutation flags or stream checkpoints.
- Added regression coverage for EventController to collapse single-read completions into one read group.
- Added assertions that visible reasoning breaks grouping and finalizes the prior read block.
- Added nested-live task rendering test for static task header while the task body shimmers.
- Added task-progress rendering tests for shimmered task-name rows and spinner-disabled fallback.
- Added a ToolExecutionComponent timing test validating bash spinnerFrame increments on 30fps cadence.
- Enabled DEC 2026 for Alacritty/VS Code and via TERM_FEATURES Sy token.
- Stopped blanket-disabling SSH for recognized direct terminals.
- Made the DECRQM probe enable sync on a positive report, not just disable.
- Extracted synchronizedOutputUserOverride so opt-out beats force-on.
- Forced authenticated ask requests to `experimental`, matching the anonymous fallback since the cookie session ignores pro upgrades.
- Kept TUI collapsed search answers full; capping now only applies in compact mode via `maxAnswerLines`.
- Preserved full multiline task pending preview instead of bounding it.
- Mapped left/right arrows to switch tabs in the extension dashboard.
- Updated agent and extension dashboard footers to show arrow controls.
- Reformatted HTTP transport assignment and reordered an import.
- Aligned handoff, reminder, and system-prompt expectations with shortened copy.
- Added HTTP transport test for required initialize failures.
- Guarded SSE startup timeout against stale connection races.
- Tracked the latest in-flight preview diff recompute in ToolExecutionComponent and exposed it through a new whenPreviewSettled method.
- Updated component paths that trigger preview recomputation to retain the returned promise instead of fire-and-forget calls.
- Updated the streaming preview height test to await settled diff recomputation before assertions, eliminating requestRender race-based flakes.
- Moved EvalBackendsAllowance and related functions to a dedicated eval-backends.ts module.
- Replaced ad-hoc brokenShellSessions tracking with a quarantineShellSession helper that also awaits the abort cleanup promise.
- Applied quarantine on timeout and cancellation paths, not just errors.
- Replaced the streaming edit diff rendering strategy with a fixed-height trailing window so partial re-diff streams stayed anchored and stopped oscillating.
- Updated streaming preview tests to assert the window remained saturated without trailing blank padding across chunked updates and still produced a real diff after finalization.
- Tuned TUI viewport repaint heuristics for pure appends and multiplexer sessions, and adjusted render-stress handling for preserved tmux scrollback.
- Added overlayRebuild intent, refactored forced-frame prep around base lines, and added frame dump support.
- Updated forced-render prep to preserve forced flags, allow unknown viewport mutation, and clear scrollback on resize.
- Introduced #syncChildOrder for child attach/reorder and skipped duplicate checks when after.atBottom was false.
- Added streaming-preview test scaffolding with VirtualTerminal, settleTerminal draining, and normalized row helpers.
- Added +Nk/+Nm turn-budget parsing with whitespace-boundary matching, multipliers, and hard `!` indicator.
- Added per-turn budget lifecycle plus APIs (`getTurnBudget`, `recordEvalSubagentUsage`) and hard-cap checks in eval runs.
- Added hard budget observability in eval preludes and docs by exposing `budget.hard` and documenting ceiling modes.
- Fixed streaming preview stutter with max-row tracking and padding, with tests for preview height and budget parsing.
