 | 1 | **`fix(safety): persist bash evidence at tool_call` (close mid-unit re-dispatch race)** | Real race condition; bash tool calls can lose evidence between dispatch and re-dispatch | `da7dd56e7` (PR #5056 → #5058) |
 | 2 | **`fix(security): harden project-controlled surfaces`** | We have a partial cherry-pick at `66ff949c1`; supersede with the full fix | `65ca5aa2e` |
 | 3 | **`fix(search): narrow native web_search injection`** | Only inject web_search context when the provider accepts it | `4370bedf3` |
-| 4 | **`fix(gsd): self-heal symlinked .gsd staging`** | Data-loss prevention — symlinked staging dir was being treated as the wrong scope | `9340f1e9b` (#4423) |
+| 4 | **`fix(gsd): self-heal symlinked .sf staging`** (path-translated) | Data-loss prevention — when the staging dir is a symlink that's broken or points outside expected scope, detect and self-heal instead of silently writing to wrong location. Path-translate `.gsd/` → `.sf/` in the port; the substance is symlink-resilience, not the path string. | `9340f1e9b` (#4423) |
 | 5 | **`fix(knowledge): scope + budget milestone KNOWLEDGE injection`** | Prevents milestone-scope knowledge from blowing the context budget | `58d3d4d6c` (#4721) |
 | 6 | **`fix(mcp-server): prevent defaultExecFn stdout-buffer deadlock`** | Real deadlock — large-output MCP tools could hang the agent | `bb747ec57` |
 | 7 | **`fix(agent-session): guard synthetic agent_end transitions`** | Session-transition race when agent_end was synthesised | `71114fccf` |
