+## Active integration checkpoint — 2026-09-06
+
+Production main remains based on a8f451e; current unaccepted release work and its
+authoritative working ledgers are in D:/CodexBuilds/Capella2-data-integration,
+branch codex/data-contract-integration, checkpoint b2d713e. It includes combined
+DATA/scenario merge dfd2e41, with286 desktop tests, strict Clippy and optimized
+builds passing on Windows/Linux. Windows R6 native record browsing, typed values,
+comments-preserving migration and save/reopen passed. Linux R6 and direct scenario
+native acceptance remain pending. Separate semantic review implementation is in
+D:/CodexBuilds/Capella2-semantic-review under independent adversarial review.
+
+User reauthorized native testing after Escape, but the Computer Use helper again
+returned its physical-Escape stop before inventory. No further native input was
+issued. Runtime sessions43338 (Linux R6) and57994 (combined Windows) were launched;
+re-inventory rather than reuse bindings when Computer Use resumes. The broader
+release remains active and incomplete. Read integration STATE/TASK_LEDGER and the
+full goal attachment10134df9-bea2-4c02-a820-67b53d6b86f7 before continuing.
