+# Resolution pass 5: general compatibility fixes
+
+Pass 5 applies after the validated scheduler pass.
+
+Expected cumulative result:
+
+```text
+116 initial conflicts
+85 after pass 1
+67 after pass 2
+50 after pass 3
+33 after scheduler pass 4
+10 paths resolved by pass 5
+23 remaining conflicts
+```
+
+## Local conflict blocks retained
+
+- `.gitignore`: keep project-specific generated-file patterns.
+- MIPS R4K TLB: keep the newer local TLB uniquification and cleanup path.
+- perf callchain/core: keep `is_user_task()` so the shared definition handles
+  kernel threads, user workers and missing user memory consistently.
+- MPTCP protocol: keep the stronger fallback lock and `allow_subflows` gate.
+- CAKE: keep newer queue/backlog accounting and tree backlog reduction.
+
+## Official conflict blocks retained
+
+- Renesas CAN-FD: use the official common mode helper after channel reset.
+- Renesas USB2 PHY: use the channel-owned reset control and official exit-time
+  assertion lifecycle.
+- MPTCP subflow: import simultaneous-connect fallback propagation.
+
+## Per-block combined file
+
+AMD microcode keeps the local cutoff-table helper while accepting the official
+Family 1Ah model-range correction from `0x7f` to `0x6f`.
+
+## Excluded high-risk paths
+
+Pass 5 leaves 23 paths covering:
+
+- ABI/KMI, OPlus symbol lists, protected exports and AFDO
+- IOMMU and Android vendor memory hooks
+- F2FS/EXT4 and pageblock state
+- Mellanox firmware reset lifecycle
+- Unix-domain socket graph collection
+
+These require ABI regeneration, full-tree build context or combined semantic
+resolutions rather than marker-side selection.
