+Dealing with PR blockers
+------------------------
+
+Incorrect or incomplete semantics
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+While working on a PR, a developer may discover that the PR depends on semantics or terminology that are either incorrect or incomplete in the FLS.
+In such cases, bring up the issue to the FLS team.
+
+Depending on the scope of the required changes, the FLS team may decide to either:
+- Enact the necessary changes in the same PR-in-development, or
+- Defer the pre-existing out-of-scope problem only when the PR-in-development remains accurate within its stated scope, and open GitHub issue to track the problem.
+
+Missing semantics
+~~~~~~~~~~~~~~~~~
+
+While working on a PR, a developer may discover that the PR depends on semantics or terminology that the FLS does not yet define.
+This may happen when the Rust Reference or other sources the FLS team may use as reference were changed irrespective of Rust releases.
+In such cases, bring up the issue to the FLS team.
+
+Depending on the scope of the required changes, the FLS team may decide to either:
+- Enact the necessary changes in the same PR, or
+- Create a separate PR to introduce the missing semantics or terms, and then update the contents of the PR-in-development.
