[feyibosslady]

Description

Implements an agent activity audit log stream component that enables security officers and administrators to search through chronological events, filter by severity levels, and inspect execution traces.

Changes

• ****: New interface and type ( | | ) with 10 mock audit log entries covering agent actions, policy violations, and admin overrides.
• ****: Added barrel export for the new audit types module.
• ****: New component with:
  • Real-time text search filtering across message, actor, action, and source fields
  • Severity dropdown filter (All / Info / Warning / Critical)
  • Color-coded severity badges using design token variants (, , )
  • Timeline view with vertical connector line and severity-colored dot indicators
  • Actor type icons (Bot, User, Shield) with inline metadata
  • Keyboard navigation: Escape key clears the search input
  • Screen reader support: , , on results count, text on severity badges
  • Follows existing codebase patterns: directive, class merging, Lucide icons, design token colors, Tailwind CSS

Acceptance Criteria

• Create
• Implement text search input and severity dropdown filter
• Render color-coded severity badges (Info, Warning, Critical)
• Ensure keyboard navigation and screen reader attributes are correctly applied
• Confirm

MergeKeeper merge status

Status: blocked
PR state: open
Mergeability: mergeable
Checked commit: 43573e12554f9248c937524aedf77bcdaca4e930.

Reason:
GitHub pull request merge request failed with 405: 3 of 3 required status checks are expected.

Next steps:
This required status check is enforced directly by the repository's branch rules, independent of MergeKeeper's own CI evaluation — a maintainer merge override cannot bypass it unless MergeKeeper is authorized to.

1. Wait for the check to pass, or fix the underlying failure.
2. To let an explicit override bypass this check going forward, add the MergeKeeper GitHub App as a Bypass actor on the ruleset (Settings → Rules → Rulesets → the ruleset → Bypass list).
