+## Integrity-Aware Caching
+
+When a workflow uses `tools.github.min-integrity`, cache-memory automatically applies integrity-level isolation. Cache keys include the workflow's integrity level and a hash of the guard policy so that changing any policy field forces a cache miss.
+
+The compiler generates git-backed branching steps around the agent. Before the agent runs, it checks out the matching integrity branch and merges down from all higher-integrity branches (higher integrity always wins conflicts). After the agent runs, changes are committed to that branch. The agent itself sees only plain files — the `.git/` directory rides along transparently in the Actions cache tarball.
+
+### Merge semantics
+
+| Run integrity | Sees data written by | Cannot see |
+|---|---|---|
+| `merged` | `merged` only | `approved`, `unapproved`, `none` |
+| `approved` | `approved` + `merged` | `unapproved`, `none` |
+| `unapproved` | `unapproved` + `approved` + `merged` | `none` |
+| `none` | all levels | — |
+
+This prevents a lower-integrity agent from poisoning data that a higher-integrity run would later read.
+
+> [!NOTE]
+> Existing caches will get a cache miss on first run after upgrading to a version that includes this feature — intentional, as legacy data has no integrity provenance.
+
 ## Security
 
 Don't store sensitive data in cache memory. Cache memory follows repository permissions.

 **Note:** The `action-mode` can also be overridden via the CLI flag `--action-mode` or the environment variable `GH_AW_ACTION_MODE`. The precedence is: CLI flag > feature flag > environment variable > auto-detection.
 
+#### DIFC Proxy (`features.difc-proxy`)
+
+Opt in to DIFC (Data Integrity and Flow Control) proxy injection. When enabled alongside `tools.github.min-integrity`, the compiler inserts proxy steps around the agent that enforce integrity-level isolation at the network boundary.
+
+```yaml wrap
+features:
+  difc-proxy: true
+tools:
+  github:
+    min-integrity: approved
+```
+
+Without this flag, configuring `min-integrity` alone performs content filtering at the MCP gateway level but does not inject the additional proxy steps. Enable `difc-proxy` when you need the full proxy-based enforcement.
+
+The flag can also be set via the environment variable `GH_AW_FEATURES=difc-proxy`.
