Operational patterns

Run history, checks, logs and integration states. All data is fictional; these examples do not execute commands or connect to services.

01 / Execution

Timeline & checks

View run workflow

Run DD-142 · Portal accessibility · 3 September 2026 · UTC

  1. Run queued

    Jamie Davis submitted the approved work item.

  2. Changes prepared

    Two files updated; checks completed with one warning.

  3. Waiting for review

    A reviewer must approve before the deployment stage.

Check results

  • Type checking

    No type errors in the preview fixture.

    Passed

  • Visual comparison

    Focus outline changed; manual review needed.

    Warning

  • Deploy preview

    Requires reviewer approval.

    Not run

02 / Diagnostics

Expandable logs

A bounded, read-only excerpt. Copying copies text only; nothing is executed.

Type-check log 4 lines · Passed

Recorded 3 September 2026, 09:17 UTC 

[09:17:00] Starting type check
[09:17:01] Checking 18 source files
[09:17:02] No type errors found
[09:17:02] Process exited with code 0

Reuse this pattern

Use native <details> for the disclosure and <pre><code> for output. Insert untrusted logs as text, never HTML. The copy controller reads textContent and announces success or failure. In a connected application, redact secrets before rendering and offer a download for large logs; do not announce every log line through a live region.

03 / Connections

Integration states

View integration workflow

  • GitHub

    Connected

    Repository access verified. Last sync: 09:12 UTC.

  • Jira

    Degraded

    Issue sync is delayed. Existing data is from 08:40 UTC; check provider health before retrying.

  • Slack

    Expired

    Authorization has expired. A workspace administrator must reconnect the integration.

  • Model gateway

    Unavailable

    No response from the provider. Connection status is unknown; do not treat this as disconnected.

Reuse: use .dd-status with a semantic color token and a written state. Include freshness, impact and recovery guidance. These four states are static specimens, not live provider health reports.

04 / Review

Changed files & diff

View review workflow

Two changed files · 2 additions, 1 removal · illustrative patch

src/portal/action.html Modified · +1 −1

Unified diff. Lines prefixed with − are removed; lines prefixed with + are added. 

@@ -1 +1 @@
-<button>Go</button>
+<button>Review changes</button>
tests/portal-action.spec.ts Added · +1 
@@ -0,0 +1 @@
+await expect(page.getByRole('button', { name: 'Review changes' })).toBeVisible();

Reuse this pattern

Keep the filename, change type and counts visible when collapsed. Escape diff content and preserve the +/− prefixes; color must not carry the meaning alone. Focusable code regions allow keyboard scrolling without forcing page-wide overflow.

These are inline HTML specimens, not a syntax-highlighting or patch-application API. Extract the markup into your own partials and supply sanitized data for a real review surface.
