 ### v0.49 — MULTI-TURN / COLD-RETURN ACTIVITY VISIBILITY REPAIR (2026-08-28)
 
-**Closed:** Multi-turn/cold-return regression in Open Question activity visibility (INVESTIGATING cue).
+**Checkpointed:** Single-turn visibility: passed. Multi-turn identity regression: repaired at 10cbcbd. Cold-return activity visibility: checkpointed subject to the canonical identity rule (`c.targetNodeId === nodeId || c.originatingTargetNodeId === nodeId`).
+
+**This repair does NOT solve** restored workspace lifecycle or reopened Finding interaction controls (see RESTORE / PRESENTATION FINDINGS section below).
 
 **Root cause:** `ThreadContributionsBadge`, `PriorContributionsSummary`, and `SecondaryPreviousLearning` all filtered contributions via `c.targetNodeId === nodeId`. Multi-turn follow-up Contributions carry a different immediate `targetNodeId` while the canonical origin remains on Findings (`originatingTargetNodeId`). When only the follow-up turn survives cold return, the filter finds zero matches.

+## RESTORE / PRESENTATION FINDINGS — MANUAL USER-PATH (2026-08-28)
+
+### Open restore / focused-workspace presentation issue
+
+The following findings were established by manual user-path testing after the v0.49 multi-turn activity visibility repair at 10cbcbd. They are **separate and additional** to that repair; the identity fix for INVESTIGING cue on Open Question cards remains valid and unimpaired.
+
+#### A. Cold return can land on underlying investigation surface rather than focused-overlay
+
+After manually completing focused investigation work, closing the browser, and returning later:
+
+- The application can hydrate into the **underlying/main investigation surface** (case overview + situation + open questions with INVESTIGING cues) rather than automatically reopening the focused-investigation overlay.
+- The main/restored surface includes: Open Questions (with INVESTIGING cues), Situation, persisted investigation content, and a saved-state message/banner stating that previous investigation state is still saved and can continue or restart.
+- **No focused overlay is automatically reopened.**
+
+This indicates there appear to be **distinct presentation states**:
+
+A. Restored underlying investigation surface (case overview)
+B. Focused-investigation overlay (opened per Open Question)
+
+The ownership / lifecycle relationship between A and B has NOT yet been traced or resolved.
+
+#### B. Restored surface + saved-state banner presents semantically odd signal
+
+The main investigation is already visibly restored when the UI simultaneously presents messaging equivalent to:
+
+> "Your previous investigation state is still saved. You can continue where you left off or start fresh."
+
+This may indicate a **restored/resumed workspace-state distinction** that is not currently obvious to the user.
+
+**Do not conclude persistence is broken.** Persistence remains demonstrated working. This is a **presentation / workspace-lifecycle observation**.
+
+#### C. Reopened focused stream loses Finding interaction controls
+
+After returning to the restored investigation and manually reopening the previously investigated focused stream:
+
+- Prior Finding proposition(s) are visible under "What this tells us"
+- The Finding text itself survives
+- **The controls "Not quite" / "Not relevant" are absent**
+
+This differs from the live current-turn focused surface where canonical Findings display those controls.
+
+**REOPENED CANONICAL FINDING CONTROLS — UNRESOLVED**
+
+Leading hypothesis (unproved): the reopened/restored rendering path may be presenting Contribution-derived observation text or another historical representation instead of the same canonical Finding objects used by the live current-turn path. **This is NOT YET PROVED.**
+
+---
+
+### Separation from prior repair
+
+The recent activity-visibility repair at 10cbcbd:
+
+- Repaired INVESTIGATING cue identity for direct/originating focused-thread identity via `c.targetNodeId === nodeId || c.originatingTargetNodeId === nodeId`
+- **Does NOT solve** restored workspace lifecycle (section A)
+- **Does NOT solve** reopened Finding interaction controls (section C)
+
+These are distinct issues with distinct boundary surfaces.
+
+### What remains proved (unchanged from prior handoff)
+
+- post-authoritative Current Understanding isolation was proved
+- Done-for-now promotion was deterministically and live verified
+- promotion survives reload
+- no case/update or extra LLM call is required for Done-for-now promotion
+
+The new manual observations are **presentation/lifecycle issues downstream of persisted state**, not evidence that the promotion seam failed. Do NOT reopen those completed v0.49 findings.
+
+### What remains unresolved
+
+| Item | Status |
+|------|--------|
+| Cold-return can land on underlying surface rather than focused overlay | MANUALLY OBSERVED — unproven presentation/lifecycle gap |
+| Saved-state banner + already-restored investigation signal | MANUALLY OBSERVED — semantic oddity of workspace state |
+| Reopened Finding proposition survives | PROVED (text persists) |
+| Reopened Not quite / not relevant controls absent | UNRESOLVED — hypothesis noted, root cause unproved |
+
+### NEXT BOUNDARY — REOPENED FOCUSED FINDING PRESENTATION / RESTORE WORKSPACE OWNERSHIP
+
+**Do NOT implement this trace now. Record as next bounded investigation.**
+
+The immediate next trace should compare:
+
+| LIVE CURRENT-TURN FOCUSED RENDERING | versus | COLD-RESTORED / REOPENED FOCUSED RENDERING |
+|---|---|---|
+| canonical Finding objects present | vs | whether same objects survive reopen |
+| Finding.id available | vs | identity continuity |
+| proposition | vs | wording continuity |
+| userDisposition available | vs | disposition survival |
+| onUpdateFindingDisposition | vs | callback availability |
+| onUpdateFindingProposition | vs | rewording availability |
+
+The trace must identify the **first boundary** where any of the fields above stop being available or stop being rendered.
+
+Also trace whether:
+- the main restored surface (A) and the focused overlay (B) are driven by **distinct lifecycle/presentation state**, and if so, what governs the transition between them;
+- the reopened Finding controls gap is a rendering-path difference or a data-model gap.
