+- Treat repo and git branch applicability as part of memory relevance, not background metadata.
+- Before relying on a memory for task planning, compare the memory's repo / branch hints against

+- Branch labels are a relevance hint, not a hard gate. Do not tell the user to switch branches or
+  dismiss a memory solely because the remembered branch name differs from the current branch.
+- Strong match: same repo and same branch, or the memory explicitly says it is branch-agnostic.
+- Verification match: same repo but different branch. Inspect the current checkout before deciding
+  whether the remembered implementation details still apply here.
+- Mismatch: different repo, or branch-sensitive memory that conflicts with the current checkout state.
+  Do not let it override the live repo evidence.
+- For same-repo different-branch memories, prefer cheap local verification before answering:
+  inspect the current branch, local files, tests, and git history as needed.
+- If the current checkout already visibly contains the remembered implementation or regression
+  behavior, you may reuse the concrete details even when the original memory came from another branch.
+- If the current checkout does not contain that implementation, keep exact implementation / PR / CI
+  details branch-scoped and only reuse clearly generic guidance.
+- If a memory mentions a concrete commit hash, merge status, or branch-local implementation, use cheap
+  local git checks like `git branch --show-current`, `git merge-base --is-ancestor <commit> HEAD`,
+  `git branch --contains <commit>`, or `git show <commit>` when helpful.

+  prefer current checkout evidence over remembered branch labels unless the memory explicitly matches
+  the same repo / branch and the checkout agrees.
