[Release Readiness] .NET 10 SR12 — candidate from main

Release Readiness — CANDIDATE for next SR (vs release/10.0.1xx-sr11)

Pre-flight mode. Surveying main (== main) against prior SR release/10.0.1xx-sr11. Shows what WOULD ship if we cut the next SR today.

Verdict — Not Ready

• [Tier 1] 2 × no-fix-yet
• [Tier 2] 1 × open-on-main
• [Advisory] Candidate mode — main CI is stale. Re-evaluate after SR cut.
• [Tier 1] Ship check BLOCKED: P/0 release-branch PRs
• [Tier 2] Ship check WATCH: CI Failure Scanner signals
• [Tier 2] Ship check WATCH: Known Build Errors
• [Tier 2] Ship check WATCH: Candidate PR for next SR cut (SR12)

Candidate PR — SR12 cut point (10.0.120)

The Candidate PR promotes a specific main commit as the base for cutting SR12 (10.0.120). The SR branch can't be cut until it merges, so its status gates the whole cycle.

No open Candidate PR yet. When ready to cut SR12, open a PR titled *Candidate* against main selecting the target commit — the SR is cut from its merge commit.

Cleanup follow-ups — 3 item(s)

These are housekeeping items that should be addressed but do NOT block this release.

Area	Details	Next action
Bug template lists SR12 version	No entry matching 10.0.[120..129] found in version-with-bug dropdown on origin/main. Top entries: 11.0.0-rc.1, 11.0.0-preview.7, 11.0.0-preview.6.	Add the SR12 version (e.g. 10.0.120) to .github/ISSUE_TEMPLATE/bug-report.yml — can land before or shortly after ship.
Milestone for next cycle (.NET 10 SR13)	No milestone matching .NET 10 SR13 exists. Once SR12 ships, open issues will have nowhere to roll forward to — but SR12 can ship first.	Create the milestone before the next cycle begins: gh api repos/dotnet/maui/milestones -f title=".NET 10 SR13" -f state=open
Stale open milestones (1)	1 milestone(s) in the .NET 10 cycle are past due (>7 days) and still open: .NET 10 SR11 (due 2026-09-08, 101 open). These represent already-shipped releases that were never closed out — accumulating open issues that should have been rolled forward.	For each: triage the open issues (close-as-fixed, move to current cycle, or move to Backlog), then close the milestone: gh api -X PATCH repos/dotnet/maui/milestones/<number> -f state=closed
