Subject: [PATCH 02/30] feat(tarko): implement elapsedMs calculation for
 assistant messages

Add timing calculation in agent kernel to populate elapsedMs field:
- Track request start time in LLMProcessor
- Calculate elapsed time from request to response completion
- Set elapsedMs in all assistant_message events
- Handle edge cases (abort, error, max iterations) with 0ms

Subject: [PATCH 03/30] feat(tarko): implement proper TTFT calculation and
 enhance timing display

Improve timing calculation to properly track TTFT vs total response time:
- Track first token time when receiving first content chunk
- Calculate TTFT (Time to First Token) separately from total response time
- Add totalElapsedMs field to event types and UI components
- Enhance TTFTDisplay to show both TTFT and total time when different
- Add detailed timing logs for debugging
- Update tooltip to show timing breakdown

Subject: [PATCH 04/30] refactor(tarko): improve timing field naming to follow
 industry standards
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Update timing field names to use industry-standard terminology:
- elapsedMs → ttftMs (Time to First Token)
- totalElapsedMs → totalResponseTimeMs (clearer naming)
- Add backward compatibility support for elapsedMs
- Update all components to use new field names
- Improve tooltips and documentation with standard terms
- Maintain API compatibility during transition period

Subject: [PATCH 11/30] feat(tarko): integrate TTFT display into message footer

Refactor TTFT display to be part of message footer for better UX:
- Extract MessageFooter component from MessageGroup
- Move TTFT display from message content to footer area
- Use subtle colors and smaller size for footer integration
- Maintain left alignment with timestamp and copy functionality
- Remove standalone TTFT display from individual messages
- Improve visual consistency with existing footer elements
- Note: secretlint warnings are false positives for React key props

Subject: [PATCH 12/30] refactor(tarko): consolidate TTFT display into
 MessageFooter Simplify TTFT/TTLT metric display by removing separate
 components: - Remove LLMMetricDisplay with colors and animations - Remove
 MessageTimestamp with mixed responsibilities - Merge all footer functionality
 into MessageFooter - Use consistent gray styling matching timestamp/copy
 button

Subject: [PATCH 13/30] fix(tarko): improve TTFT/TTLT display precision and
 clarity

- Use ms precision for all time displays instead of s
- Add distinct icons (FiZap for TTFT, FiActivity for TTLT)
- Ensure consistent gray styling for both metrics
- Add clear hover tooltips explaining TTFT and TTLT
