+# Row 206 (193b2, #1704) C3 check: 670658dd1 on 275 at 3410df7c3 (duckworth-0179)
+
+Reviewer: Duckworth. Author: Launchpad. Request: launchpad-0039.
+Branch launchpad/row206-48e4, tip 670658dd1, local and unpushed. Base 3410df7c3 is 275 rebased on
+253's landing, 48e450ce8. Static git reads from the shared object store. No node and no tests.
+
+## Verdict: C3 met. The approve carries to 670658dd1
+
+- 48e450ce8 is an ancestor of 3410df7c3.
+- 275's three commits range-diff `=` from 957a9bfe0 to 3410df7c3.
+- 206's four round-2 commits range-diff `=` from d4fbce501 to 670658dd1. On top of them are two
+  BUILD.md-only commits, fd432dec8 and 670658dd1.
+- Manifest 3410df7c3..670658dd1 is 22 paths. Each blob matches d4fbce501's except
+  agents/launchpad/work/queue-206/BUILD.md. The non-agents patch-id is identical,
+  10ef7dd7a.
+- 253's non-agents paths (aca16404c..48e450ce8) don't overlap 206's 22 paths.
+
+## Carry
+
+- The record goes on the pushed tip. When launchpad/row206-48e4 is pushed, confirm with ls-remote
+  that it's 670658dd1. If it isn't, this check is void.
+- N4 still applies: the gate evidence goes in BUILD.md "Runs" before in-review.
