- Synchronized shimmer progression by switching `shimmer.ts` to a shared 2-second phase sweep, with crest/head position interpolated across the full visible span.
- Updated classic and KITT intensity calculations so shimmer starts at index 0 and reaches index length-1 together for any task row length.

- Added atomicTokenPattern support to treat image and paste markers as indivisible tokens, enabling atomic deletion on backspace and forward-delete instead of character-by-character removal.
- Extended image marker format to include pixel dimensions [Image #N, WxH] and updated paste marker format to [Paste #N, +X lines] or [Paste #N, Y chars] with consistent comma-separated metadata.
- Implemented accent styling for paste markers in editor rendering while preserving hyperlinks for image markers, improving visual distinction between marker types.

- Adjusted completion defaults for active-session model preference, fallback parsing, and slow-tier effort handling.
- Replaced `readGroup.finalize()` with `readGroup.seal()` when ending assistant content, after tool runs, and at trailing read-group flushes to keep grouped reads in the live region until late results settle.
- Documented the fix in `packages/coding-agent/CHANGELOG.md` for grouped read rows that could freeze on terminals when results arrived after a sibling tool closed the run.
- Added a sealed state to `ReadToolGroupComponent` to force-close a read group when a turn ends without a read result.
- Updated transcript finalization to treat pending read entries as active unless the group is sealed, preventing premature finalization when outputs are still in flight.

- Added `isUserInterruptAbort` and `shouldRenderAbortReason` helpers so interrupt handling can distinguish Esc-based aborts from other abort reasons.
- Updated assistant transcript rendering to suppress the `Interrupted by user` line while continuing to show generic or other abort labels.
- Updated plan-review and transcript container tests to assert interrupted assistant messages no longer render the redundant interrupt line.
- Removed `<turn-aborted>` guidance injection from `transformMessages`, deleted `turn-aborted-guidance.md`, and dropped the synthetic abort note path for aborted/error turns.
- Updated `c`/`.` continue shortcuts to submit `manual-continue.md` as a hidden synthetic `developer` message via `session.prompt(..., { synthetic: true })` instead of sending an empty user turn.
- Updated tests and changelog notes in AI and coding-agent to reflect the revised abort-context and continue behavior.
- Computed live commit state from render diffs and drove native scrollback via safeLength.
- Fixed volatile live tool rows committing only after stream finalization in native scrollback.

- Deduplicated prompt-history results by session path in mergeSessionRanking to avoid duplicate suggestions.
- Adjusted resume ranking to favor literal-token matches by recency, then fallback to fuzzy score.
- Updated workflow detection in `workflow.ts` to recognize only the lowercase `workflowz` token for detection and highlighting.
- Changed workflow instructions and tips to reference the new `workflowz` trigger for eval fan-out behavior.
- Updated workflow tests to assert `workflowz` matches correctly and previous `workflow`/`workflows` forms no longer trigger.
- Cached setting path segments and memoized `Settings.get()` results, clearing caches on updates.
- Triggered session-name and session-accent callbacks only when effective values changed, with error-safe dispatch.
- Memoized status-line and interactive accent resolution with cache invalidation on settings/theme/session changes.
- Added regression tests for keybinding precedence, status-line, settings, and accent cache behavior.
- Built canonical and alias key maps for action/custom handlers and rebuilt them on changes.
- Preserved the first handler when custom key alias collisions occurred during rebuilds.
- Exported canonicalKeyId and addKeyAliases from keybindings for external use.
- Updated classic shimmer to compute band position from elapsed time at 30 cells per second instead of a fixed sweep duration.
- Updated KITT shimmer to use fixed-speed ping-pong motion over the same 2xrange cycle so round-trip timing scales with message length.
- Added first-party-first provider priority defaults for model ranking.
- Consolidated model resolution to use getModelMatchPreferences from session settings.
- Prioritized providerPriorityRank ahead of usage rank when picking preferred models.
- Added second-pass fallback to default-model or API-key-valid matching order.

- Added `getCredentialOrigin` and `getEnvApiKeyName` to classify auth source.
- Surfaced provenance tags in the `/login` and `/logout` provider picker.
- Made the picker search filter match credential origin and env var name.
- Added coverage for credential-origin precedence and env naming.
- Added an interrupt state in EventController to switch the working label to `Interrupting...` and suspend intent-driven updates until the turn resets.
- Called `notifyInterrupting()` from streaming-interrupt paths in InputController and exposed it on InteractiveModeContext so Esc acknowledgement shows immediately while tools tear down.
- Added tests to verify loader acknowledgement, freeze of late intent updates during interruption, and label updates resuming on the next agent start.
Route follow-up shortcut submissions through the builtin slash-command dispatcher before queueing them as deferred prompts.
Added regression coverage for /goal set submitted through InputController.handleFollowUp while a stream is active.
Fixes#2038
handleCtrlZ called process.kill(0, "SIGTSTP") unconditionally; on
Windows the runtime rejects the signal name with TypeError, which
propagated out of the TUI input dispatcher and crashed the agent
with an [Uncaught Exception]. Even on POSIX the call could fail
(sandboxes that block sending to pid=0, runtime-reserved signals),
and a thrown error after we already stopped the TUI and registered
a one-shot SIGCONT listener left the UI stranded with a leaked
handler that would fire on the next unrelated continue and try to
re-start() an already-running TUI.
Branch on process.platform first so Windows shows a status notice
and never calls process.kill, and wrap the POSIX kill in try/catch
that removes the SIGCONT listener and re-starts the TUI on failure.
