 User prioritizes Capella-like hierarchical architecture and correct ports. release-diagram-port-correction.md records the correction; release-port-contract.md is being finalized before implementation. No release completion claim.

 Latest native checkpoint ready: D:/CodexBuilds/Capella2-release1-01a06e2e/ui-hierarchy-reviewed/arcadia-studio.exe SHA2563603AC957B6E16B4321F7FB7E759B3A2265357679DB8F27DD9ED5642B7E02179. Not launched yet. Old Studio window723086 has dirty marker, so inspect and preserve any unsaved changes before closing (do not infer it is safe from the earlier no-edit state).
 
 Typed-port work isolated at D:/CodexWorktrees/Capella2-typed-ports, branch codex/typed-port-contracts, from c20a207. port_contract_design owns core model/ports/validation/references/session/transitions/demo/projection + non-language tests; capella_startup_diagnosis now owns persistence/migration/language/server/API/reST + source/migration tests. They coordinate shared schema but never edit the same files. Root main remains buildable during their implementation. Temporary model-capacity errors were retried on the same agents; both resumed. Full core port/schema3 acceptance pending.

+## Updated objective and drag bug
+
+Authoritative objective is now attachment20fca018-f8ce-4cc0-86e7-8ead5d325630 (read fully). It retains first-release scope and adds modular source projects/includes, stable drag/reselection, and directly editable behavior/scenario diagrams. Root fixes drag; hierarchy_port_review is read-only mapping direct behavior manipulation/persisted geometry interfaces. Active port work remains aligned.
+
+Root verified drag bug: MoveNode returned a placement identity, dropping semantic highlight; SelectNode returned early for that same placement. Handler now selects the moved semantic element and restores its property draft; same-card click from a clean placement inspector restores semantic selection. Dirty placement identity edits defer to gesture release so existing remap behavior survives. Focused repeated drag/reselection/property-edit/undo regression and existing placement-identity regression pass. Native build ui-hierarchy-reviewed replaced before first launch, current SHA25630FA95CA9C606B20EAA5B4FA08AE04EB47CCB1A2498C05C0C26F2B049F006BE5; native checking now.
+
+Original Capella: created component exchange C1 between Aircraft and IFE System; it automatically made ComponentPorts. Source CP1 properties explicitly show provided/required interfaces, allocated/realized ports, Standard/Flow kind and Unset/In/Out/InOut direction; generated source is Flow/Out. Opened its allocated-port chooser, containing function ports under Aircraft-assigned functions. No port allocation committed yet; chooser remains open. Component Exchange tooltip requires same port kind; main contract amended to reject typed Standard/Flow mismatch, both workers notified. Unknown screenshot/foreground mismatch interrupted picker selection; no unchecked retry or guessed input. Capella later restored at1008×762 with modal partly outside main window; use full dialog screenshot only after fresh valid observation.
+
+## Drag selection verified; typed-port integration next
+
+Root full desktop71 tests and strict desktop all-targets Clippy passed (session60951). Reopened current SHA30FA95CA checkpoint through native CUA, fresh window527250. Dragged an initially unselected Report distress activity, clicked the same moved card, edited its name to Report distress at sea and applied: semantic highlight and properties remained correct throughout; containing participant expanded. Save As is pending, not verified: the helper targets a16×16 primary capture for modal1706878 alongside a1186×713 related screenshot and failed UIA set_value/coordinate operations; a later refresh detected user input. Do not claim the fixture exists, overwrite or discard unsaved changes. Both prior Studio windows were absent on fresh inventory, so old unsaved geometry is not assumed recoverable. Current default native layout verified; current minimum resize still pending.
+
+Port core0d14438 and migration/source/APIb9f88ce are committed on codex/typed-port-contracts, isolated worktree clean. Integrate together, retaining main hierarchy reflow/allocation_summary changes. Handoffs release-port-core.md and release-port-migration.md record actual tests and APIs. Core worker reported125 total core tests including9focused port tests; migration worker31focused core+20server tests and strict Clippy. Root integration checks, desktop typed controls/glyphs and native port acceptance remain pending. Migration worker now independently reviews core ports; hierarchy reviewer designs modular source projects. Direct behavior editing design reuses contextual Diagram placements; interface adoption/implementation remains ahead.
