A thread in a project with no git remote (e.g. TRUSK, a folder of repos with repositoryIdentity: null) could never link or read a Linear issue. link_issue {repository:"CO", number:130, provider:"linear"} failed with "Issues cannot be browsed for this project's host yet.", because IssueService.requireProject only accepts references that match the project's own issue sources, which come from its git remote or a per-project Linear team binding. A project with neither has no sources at all.

Fix

• IssueAdapter.resolveReference (optional): an adapter may resolve a repository the caller names outright. Linear implements it by mapping a team key to the connected account that can see that team (environment account first, then saved accounts). Matches are cached for 10 minutes.
• IssueProviderRegistry.resolveReference asks those adapters, filtered by provider/host. IssueService.requireProject uses it only after the project's own sources miss, so GitHub/GitLab/Bitbucket/Azure routing is unchanged. An unknown team now fails with "No connected linear account can read OPS." instead of the misleading host message.
• MCP tool contract: repository is the Linear team key (CO for CO-130), number is the trailing digits, and provider is linear. This is documented on the fields and on read_issue/link_issue. read_issue's url still never selects an unlinked issue, which existing tests guard. Once the issue is linked, the Linear URL matches.
• User docs: a thread can link any Linear issue a connected account can see.

Linear UI follow-ups (web)

• Settings → Linear accounts: the account name and email kept collapsing to "N…" next to a long team list. The teams now sit on their own truncating line, and hovering shows the full list.
• Linked items panel: a pull request attached to a linked issue appeared twice (once in the thread list, once under the issue) and was never nested under its issue. An unstacked thread pull request that the tracker also reports now renders once, with its full row, under that issue. Stacked layers stay in the list. The matching rule is tested in pullRequestListLines.test.ts.

Tests: host-less project + Linear issue (plus an unbound Linear team on a GitHub project) in IssueService.test.ts, and team→account resolution and caching in LinearIssueProvider.test.ts. vp test run apps/server/src/issue apps/server/src/mcp/toolkits/issues apps/server/src/workItems passes (361 tests), and tsc --noEmit passes for apps/server. Web: vp test run apps/web/src/components/pullRequest/pullRequestListLines.test.ts apps/web/src/components/issue passes (115 tests), and tsc --noEmit passes for apps/web.
