 **Next boundary:** FOCUSED WORKSPACE COMPLETED-TURN / ACTIVE-TURN LIFECYCLE

+## v0.49.7 — NARROW COMPLETED-RESULT REPAIR (answer-affordance contradiction)
+
+- **Status:** CLOSED / CHECKPOINTED
+- Previous broader completed-turn lifecycle repair was discarded (restored to checkpoint dac19a3)
+- Narrow repair: a reopened completed turn preserves existing current-result presentation but NO longer exposes a response textarea for the already-answered question
+- Repair mechanism: added `!hasAnswer` (`Boolean(focused?.answer)`) to the textarea render condition in `FocusedQuestionBody` — line 186 of `reasoning-workspace.jsx`
+- Explicit follow-up selection resets `answer` to null via `setFollowUpQuestion()`, creating unanswered state and exposing textarea
+- Fresh investigation behaviour preserved (first-turn textarea still appears)
+- Latest completed turn intentionally remains as current result (not moved into Previous Learning) — deferred to a later presentation/lifecycle decision
+- No persistence changes, no new lifecycle enums, no new state fields added
+- No LLM calls during verification or tests
+- Pre-fix regression: OLD condition (`shouldShowResponseTextarea_OLD`) incorrectly returned `true` for completed turns (defect proved)
+- Post-fix: 97/97 targeted tests PASS
+- Build: PASS
+- Playwright live reopen: no "Formulating your question…" regression; completed current result shows NO textarea
+- Playwright explicit follow-up: selected follow-up becomes current QUESTION, fresh textarea with `What do you know about this?` placeholder appears
+- Return to overview: UNCLEAR + INVESTIGATING · 3 learned contributions preserved
+- Live fixture: reused existing 3-contribution onboarding investigation (no cold reload)
+
+### Unresolved boundaries (deferred)
+
+- latest-completed-turn → Previous Learning repartition (intentional defer — separate presentation/lifecycle decision)
+- workspace control UX wording ("Back to open questions" / "Done for now" / "Close investigation")
