 - [x] Add an explicit source-context picker or display for Tasks that can represent host, provider account, and project/source.

 - [x] 2026-06-12: Marked repo-id/path compatibility adapters complete after hardening the renderer project-host selector to merge repo-derived compatibility rows when hydrated project/setup arrays are empty or partial, alongside existing shared projection, persistence backfill/sync, automation context migration, and pending worktree context coverage. Verified with selector/projection tests, persistence tests, targeted oxlint, full `pnpm run typecheck`, and `git diff --check`.
 - [x] 2026-06-12: Marked the Host copy audit complete after replacing remaining visible stale SSH/project wording in paired-web project creation errors, Settings SSH search entries, AI Vault SSH-host workspace copy, and SSH shutdown errors. Verified with a stale-copy scan showing only comments/tests/technical internals, focused SSH IPC tests, targeted oxlint, full `pnpm run typecheck`, and `git diff --check`.
 - [x] 2026-06-12: Completed Settings ownership/account rows by adding a shared provider Host scope control with a Change Host action that opens Settings > Active Server from GitHub/GitLab/Linear/Jira account surfaces and GitHub/GitLab API budget panels. Existing ownership diagnostics still distinguish desktop-client versus remote-server credentials, and rate-limit panels show the budget Host scope. Verified with settings ownership, RuntimeEnvironmentsPane, provider account, source-control card, task-tracker card, Jira card, and rate-limit panel tests, targeted oxlint, full `pnpm run typecheck`, and `git diff --check`.
+- [x] 2026-06-12: Completed Tasks account/host metadata by showing repo-backed account labels in source summaries when GitHub/GitLab accounts differ by Host, while preserving host labels, provider identities, Linear workspace names, Jira site names, and unavailable-host status in labels/titles. Verified with source-summary and repo picker tests, targeted oxlint, full `pnpm run typecheck`, and `git diff --check`.
