️ RC 2 component build — branch pins + update paths

[!IMPORTANT] Branch pins are read from release/11.0.1xx-rc2 (eng/Version.Details.xml — public git). This is NOT a confirmed official build; this public workflow cannot resolve the authoritative release designation. VMR is intentionally different: there is no dotnet/dotnet subscription on a cut prerelease branch because the Maestro channel can differ from the official release source of truth; reconcile that pin locally against the official SDK/runtime build.

Run release readiness for release/11.0.1xx-rc2: resolve the official RC 2 SDK/runtime build from the authorized release source of truth, reconcile the MAUI SDK/VMR pin locally to that build, and verify only the dotnet/android + dotnet/macios inbound subscriptions are wired to the .NET 11.0.1xx SDK RC 2 channel.

The Upstream column is a hard git fact (not an inference): it compares our pinned SHA against the tip of each component's same-named branch (release/11.0.1xx-rc2 — derived, never hardcoded) via the public compare API. ⬆️ N ahead means the source moved past what we bundle — an FYI you may want to pull in, not a required bump (maui pins blessed builds deliberately, so those commits may be post-release churn or not yet blessed).

Component	Branch pin (bundled)	Commit	Update path / flow signal	Upstream (vs our pin)
dotnet/dotnet (VMR / SDK)	11.0.100-rc.2.26458.109	c65c25f	️ local official-build reconciliation — no Maestro subscription by design	— no same-named upstream branch
dotnet/android	37.0.0-rc.2.2443	9f52486	❌ none seen — sub may be missing	— no same-named upstream branch
dotnet/macios	26.5.12248-net11-rc.2	d768383	❌ none seen — sub may be missing	— no same-named upstream branch

Update-path legend: Android/macOS-iOS — open dep-flow PR · ✅ merged ≤ 14 d · ⚠️ newest merge > 14 d · ❌ no PR trail (subscription may be missing). Confirm those two subscriptions with darc get-subscriptions --target-repo https://github.com/dotnet/maui --target-branch release/11.0.1xx-rc2. VMR — ️ no subscription by design; reconcile locally against the official SDK/runtime build.

Upstream legend: ✅ current = our pin is the tip of the component's release/11.0.1xx-rc2 branch · ⬆️ N ahead = that branch has N newer commit(s) than we bundle (FYI — may be post-release churn or not-yet-blessed work; not necessarily a bump you need) · ⚠️ diverged = our pin isn't a clean ancestor of the branch tip (build tag / different line) — compare manually · — = couldn't determine (no same-named upstream branch, or the compare API was unavailable). Branch is derived from the survey ref, never hardcoded. dotnet/dotnet (VMR) advances constantly; its upstream drift is informational because the official SDK/runtime build, not branch tip or Maestro feed, selects the release pin.

Consumer installability

Status: unknown - Consumer installability could not be evaluated.

Exact feed URLs and credential setup are intentionally local-only. Re-run with -PublicSafe $false and the confirmed workload-set CLI version to generate an isolated <clear /> configuration. If an authenticated source is required, use a short-lived Packaging Read PAT through NuGet credentials; never place it in the tracker or repository.

No blocking items

Cleanup follow-ups — 1 item(s)

Not release-blocking — these are post-ship housekeeping items to track separately.

Bug template versions	11.0.0-rc.2 NOT in .github/ISSUE_TEMPLATE/bug-report.yml version-with-bug dropdown on net11.0. Top entries: 11.0.0-rc.1, 11.0.0-preview.7, 11.0.0-preview.6.	Add 11.0.0-rc.2 to the dropdown (PR against net11.0). Not release-blocking — this is post-release cleanup so users can file bugs against the right version.

Authenticate darc and run darc get-subscriptions --target-repo https://github.com/dotnet/maui --target-branch release/11.0.1xx-rc2.
RC version	READY	release/11.0.1xx-rc2 has PreReleaseVersionLabel=rc and PreReleaseVersionIteration=2.	No prerelease-version action needed.

Maestro PRs	READY	No open Maestro PRs target release/11.0.1xx-rc2. (Dependency-flow PRs targeting the inflight net11.0 branch are tracked by net11.0's own readiness, not this branched preview.)	Continue monitoring for new dependency-flow PRs.
