 **Current semantics:** Invokes `doneForNow` callback (semantic action). Button preserved unchanged — no modifications.
 
+##### v0.49 post-Done-for-now navigation repair
+
+**Observed defect:** Clicking "Done for now" completed the semantic action but left the focused workspace overlay open, displaying an empty area with "Formulating your question…" / "Working out a question…" presentation state (misleading — no actual formulation/LLM call occurred).
+
+**Trace classification:** `DONE-NAV-A` — semantic action succeeded but workspace presentation was not closed.
+
+**Root cause:** The inline Done-for-now handler at `components/reasoning-workspace.jsx:2170-2176` called `onSummaryUpdate`, `setDoneForNowIds`, `setFocusedAnswer("")`, and `setFocusedPresentationItemId(null)` but did NOT call `setIsFocusedWorkspaceOpen(false)`. Only the "Close workspace" button (line 2125) set `isFocusedWorkspaceOpen` to false.
+
+**Classification of residue:** Presentation-only. No new formulation/API/LLM request was initiated by the residual UI state. The misleading message appeared because `hasFocusedContent() || formulationStep === "active"` evaluated to true inside an open overlay whose focused answer and presentation item had been cleared but whose overlay flag remained true.
+
+**Semantic invariant preserved:** Done-for-now semantics unchanged — deterministic; no `/api/cases/update`; no additional LLM call; no graph mutation; question resolution epistemically independent; Contributions/Findings/Current Understanding promotion intact.
+
+**Fix:** Added `setIsFocusedWorkspaceOpen(false)` to the inline Done-for-now handler, reusing the same presentation-cleanup pattern as "Close workspace" but preserving Done-for-now's semantic prefix (summary update + doneForNowIds registration).
+
+**Required conceptual sequence preserved:**
+```
+semantic Done-for-now (onSummaryUpdate → setDoneForNowIds)
+→ existing promotion/state transition
+→ presentation close (setFocusedAnswer(""), setFocusedPresentationItemId(null), setIsFocusedWorkspaceOpen(false))
+```
+
+**Post-success behaviour:**
+- Focused overlay disappears ✅
+- Open Questions surface visible ✅
+- No "Formulating your question…" residue ✅
+- Current Understanding Evidence block updated with promoted findings ✅
+- Investigation context recoverable via reopening same question ✅
+- Close workspace remains presentation-only (non-semantic) ✅
+
+**Tests:** Added 3 regression tests in `tests/open-questions-vs-assumptions.test.jsx` under "post-Done-for-now workspace closes" describe block. Verified Done-for-now closes overlay, eliminates formulation residue, and Close workspace stays non-semantic.
