 - `address_truth_harness_phase32_planner_selected_chain_end_to_end.json` now uses the same assertions across selected-counterparty entity grounding, incoming/outgoing/net value-flow, document evidence, and movement evidence follow-ups.
 - `agent_semantic_pack_builder` now preserves these expected catalog-alignment fields in the reusable source catalog and adds the `planner_catalog_alignment` tag, so future mixed AGENT packs can deliberately select planner-brain regression probes instead of relying on hand-picked replay filenames.
 - The new `turnaround_11_planner_brain_alignment_mix` builder recipe generates `address_truth_harness_phase83_planner_brain_alignment_mix.json`, a 20-step mixed canary that crosses selected-counterparty value-flow, open-organization totals/comparison/ranking, broad-evaluation continuity, metadata drilldown, and off-domain living-chat safety.
+- The phase83 live replay now confirms that selected chains match the reviewed catalog top match across the mixed planner-brain pack. The remaining failure is not catalog arbitration: 1C/MCP fetches abort before confirmed business evidence is available.

 ## Next Step
 
-The next safe step is still to re-run live replay once the 1C side is actively polling the proxy. The first live replay candidate should be `address_truth_harness_phase83_planner_brain_alignment_mix.json`; only after it is executed, reviewed semantically, fixed/rerun if needed, and accepted should it be saved into autoruns as a legacy AGENT pack. In parallel, local-only consolidation can continue by hardening additional planner-autonomy specs with expected catalog-chain assertions and using `alignment_status`, alignment reason-code telemetry, truth-harness artifact surfacing, the soft divergence warning, `catalog_alignment_ok`, and the representative guard to find remaining manual branches where selected chains diverge from reviewed catalog-fabric intent.
+The next safe step is to restore/verify the 1C polling side and re-run `address_truth_harness_phase83_planner_brain_alignment_mix.json` as the main live acceptance candidate. The planner-brain invariant is now proven in replay (`catalog_alignment_ok=true`); the remaining acceptance gap is confirmed business evidence. Only after phase83 is semantically accepted should it be saved into autoruns as a legacy AGENT pack. In parallel, local-only consolidation can continue by hardening additional planner-autonomy specs with expected catalog-chain assertions and using `alignment_status`, alignment reason-code telemetry, truth-harness artifact surfacing, the soft divergence warning, `catalog_alignment_ok`, and the representative guard to find remaining manual branches where selected chains diverge from reviewed catalog-fabric intent.
