Summary: Chronological events with explicit dates, descriptions and current state.

Use the pinned approved default profile. Pending roles in that profile use-and-report their decision IDs; this does not approve them. Proposed profiles are preview-only and blocked for delivery. Heritage profiles are historical-only. Deprecated or heritage roles are blocked for new approved-profile mappings. Consume roles within their documented scope, never primitives. Release numbering does not approve profiles or tokens.

State dependency disclosures: D-007

States: default, current
  default: Divider along the event sequence. [Ordered list and visible time.]
  current: Emphasized start border. [aria-current and explicit Current text.]

Keyboard:
  Tab / Shift+Tab: Reach event links and actions. The sequence is not focusable.

ARIA: Ordered list with time elements
Responsive: Wrap labels and actions without changing source order. Use logical spacing in RTL. Preserve native target sizes at both densities; only bounded data regions may scroll horizontally.
Portability: Read events as an ordered list with explicit time and status text. The caller supplies order; the component does not reorder unknown dates. Lines support the sequence without becoming the only status channel.
  native: Use equivalent native semantics and approved roles; record any unsupported behavior as a mapping deviation.

Rules: use only these values; no invented colours; radius 0; borders 1px (2px emphasis); focus is a 1px dashed ring, selection is a fill;
do not restyle unrelated elements; report deviations per agents/consume.md; record theme.lock.json at the pinned revision.
