 **Next step:** product-level review of the Investigation Report experience — do not automatically change implementation.
 
+### Iterated Five — Report Learning Semantics (2026-10-02)
+
+**Resolved question:** Should "What the investigation surfaced" represent learning produced by investigation history, or only learning attached to questions that are currently closed-for-now?
+
+**Answer:** Only learning attached to questions that are currently closed-for-now.
+
+```
+What the investigation surfaced
+=
+eligible provenance-linked learning associated with
+questions that are currently closed-for-now
+```
+
+**Qualification:** `closed-for-now != final`, `!= settled`, `!= conclusively answered`.
+
+**Re-open semantics:**
+
+```
+Done for now → question may contribute to What the investigation surfaced
+
+Re-open:
+  → question removed from resolvedNodeIds
+  → surfaced-learning entry disappears
+  → Contributions remain
+  → Findings remain
+  → provenance remains
+  → question becomes independently representable in What remains unresolved
+```
+
+Re-open does NOT erase investigation history. It changes current closure state.
+
+**Provenance/currentness boundary:**
+
+Canonical provenance survives Re-open (`Question → Contribution.targetNodeId → Contribution.id → Finding.contributionId`). However:
+
+```
+Finding eligibility ≠ epistemic currentness
+```
+
+Canonical Findings contain no explicit marker (`current`/`historical`/`superseded`/`replaced`/`authoritative`/`episode/version`). Re-investigation can append newer Contributions/Findings while older eligible Findings remain. Retained Findings can prove what surfaced historically, but must not be treated as deterministic evidence that an older proposition remains the latest/current truth.
+
+**Persistence diagnosis:** No resolvedNodeIds persistence defect was found. The fixed investigation's `resolvedNodeIds=[]` was explained by the deliberate historical Re-open of node nrx08i0. Done-for-now produced the closure marker; ScenarioForm preserved it; canonical save/load preserved it; Re-open intentionally removed it.
+
+**Deterministic protection:**
+
+```
+tests/graph/investigation-learning-projection.test.js   7/7 PASS
+tests/ui/v060h-report-identity.test.jsx                 18/18 PASS
+```
+
+Tests establish: (1) eligible closed-for-now question included; (2) reopened question omitted even while Contributions/Findings remain; (3) canonical provenance retained; (4) unresolved representation remains independent.
+
+**Production state:** No production or test change required. Current resolvedNodeIds admission gate is semantically correct. This checkpoint records a currently closed-for-now boundary decision, not a completed/finalized/settled outcome.
