- Migrated 288 lines of scattered error classification logic from `utils/error-id.ts` into a cohesive `packages/ai/src/error/` module with 13 specialized submodules covering flags, classes, OAuth, providers, rate-limiting, and finalization.
- Replaced 100+ generic `Error` throws across 60+ provider and registry files with semantic `AIError.*` classes (e.g., `AIError.MissingApiKeyError`, `AIError.OAuthError`, `AIError.ProviderResponseError`), improving error diagnostics and retry logic.
- Consolidated error utility imports from `pi-utils` and scattered classification functions into a single `AIError` namespace, reducing coupling and simplifying error handling across all packages.
- Added a check to restore the live "Working..." loader when streaming events occur after a transient status overlay clears the UI.
- Updated `ensureLoadingAnimation` to re-attach the animation to the status container if it is missing.
- Improved thinking loop detection logic by refining text normalization and treating stalls as retryable errors.
- Instrumented the agent session to recognize thinking loop markers within retryable error conditions.
- Automated the clearing of stale error banners upon successful auto-retry execution.
- Added comprehensive test coverage for chunked thinking loop errors and banner management.
With display.showTokenUsage on, the usage row was rendered inside the
assistant block above the turn's tool blocks. Finalizing the assistant
block was therefore deferred, and the late append recommitted the
already-committed tool rows, duplicating them in scrollback (worst with
parallel tool calls).
The assistant block now always finalizes as soon as a tool-call appears,
and the usage row is emitted as a standalone finalized block below the
turn's tool blocks across all three render paths (live event-controller,
transcript rebuild, agent-hub). The now-dead setUsageInfo/#usageInfo path
on AssistantMessageComponent is removed.
- Added a focused-agent left-key input listener that consumes double left taps when the input is empty.
- Routed focused session left-tap behavior through #handleFocusedLeftTap so it matches the Esc-style unfocus timing.
- Updated tests/fixtures for the new listener flow and refreshed a hashline block-edit error assertion.
- Added a SessionFocusController to switch transcript and input context between main and subagent sessions.
- Added agent-hub Enter activation and double-left return behavior for focused local agents.
- Added view-session-based event and render logic to avoid stale focus-session state.
- Added status-line focused agent display with ghost icon and focused-mode border dimming.
- Handled frame shrink by re-anchoring windowTop and chunkTo at commit boundaries.
- Reset committedRows when the frame shrank into committed content to keep history immutable.
- Treated geometryChanged like overlay when advancing chunkTo to stabilize repaint commit timing.
- Updated regressions to assert stable scrollback prefixes and no clear-home/dclear repaint bytes.
- Updated EventController to keep foreground render mode active from agent_start through agent_end so live-region rebuild remains enabled during a turn.
- Pinned stop-reason assistant errors to the editor banner and suppressed the transcript's inline Error line while pinned, then restored it on the next agent_start.
- Added tests covering error-banner suppression/restoration and eager native scrollback rebuild ordering before loading animation.
- Added a persistent error banner so stream errors survive transcript scroll.
- Cleared the banner when the next turn starts.
- Skipped pinning for aborts and normal stops.
