🤖 Aspire triage pass — 2026-10-01 13:14 UTC

Area: area-dashboard
Kind: bug
Repro: yes-minimal — see lines 15–30 of the issue body
Affected version(s): latest image (latest Aspire release: 13.6.0; exact image version not pinned)
Severity: S2 — the published dashboard container cannot start, and no workaround is provided

Urgency: ⚪ backlog — no milestone
Reason: the failure is actionable for the active release train, but the required 13.6 milestone is not open; policy requires falling back to backlog

Suggested owner(s): James Newton-King (@JamesNK) (score 96), backup Mitch Denny (@mitchdenny) (score 18)
Evidence:

• JamesNK merged [release/13.6] Keep dashboard run menu open when pinning #20546, Enable project-backed dashboard commands and fix DCP restart races #20532, and Update Fluent UI to v5 RTM #20527 in area-dashboard within the last 30 days
• JamesNK closed [Dashboard] Mark historical resource states and endpoint links as snapshots #19783 as completed in area-dashboard
• CODEOWNERS lists James Newton-King (@JamesNK) for src/Aspire.Dashboard/**
• mitchdenny merged [release/13.6] Remove dashboard terminal navigation entry points #20562, [release/13.6] Simplify terminal dock empty state and link styling #20541, and Simplify terminal dock empty state and link styling #20537 in area-dashboard within the last 30 days

Confidence: medium
Needs human?: yes — expected milestone 13.6 is not open; confirm release routing

This probably belonged here dotnet/dotnet-docker#7387 instead. Closing
