 - Independent core review reproduced alias reservation and same-transaction allocation replacement defects; fixes have focused regression evidence. Typed desktop integration `fa096ce` passed full checks and native creation/generation, undo/redo, save/reopen and no-op synchronization trials. Long-reference previews were inspected at 1440×900 and 1100×700; detailed evidence is in STATE.md.
 - Per-diagram pins and labels, source/API parity and shared orthogonal routing are implemented in `4e5a88d`, `a7c6f96`, `68b1eff` and `30c7db1`. `65fa9ab` resolves all six reproduced default SA label-overlap pairs. Native OA/SA editing, movement/undo, fold restoration, save/reopen, SVG inspection and short gestures at 1100×700 passed. Routing code/native acceptance and independent native follow-up are complete at `23535b4`; exact scope is recorded in release-routing-verification.md.
 - The source experiment passed 23 tests, but an independent probe reproduced positional item-comment misattachment, shorthand description rejection and unsupported deletion. Whole-model equality does not establish source-comment fidelity. The production updater retained comment attachment on the same reorder probe; extend its parser/updater instead of copying the experimental parallel implementation.
-- Current behavior diagrams derive geometry and only handle selection; direct behavior editing remains a product gap. The source editor retains modular accepted source; nested element syntax is implemented and under native acceptance. Port/exchange/steps shorthand remains an independent future implementation slice required by the current authoring strategy.

The source editor retains modular accepted source; nested element syntax and cross-file graphical updates passed Windows/Linux native acceptance at4e8575b. Port/exchange/steps shorthand remains an independent future implementation slice required by the current authoring strategy.
 - Independent source review exposed declaration/comment reassignment during UUID changes and swaps, Linux FIFO hangs during disk admission, file-mode changes on save, and overlong detached-file receipt lifetimes. Command provenance, pre-open regular-file admission, permission retention and saved-detach receipt retirement resolve the reproduced cases. Exact probes and test scopes are in STATE.md.

 Accept native per-file editing, safe project saves and exact source Undo, then extend production source parsing/updating using the independent probe findings as regressions and integrate REST bundles. Linux routing is accepted with actual WSLg Save/reopen; all11 current Linux disk integration tests also pass. Full release Linux acceptance remains open. Prototype persisted direct behavior gestures next. Continue R3 reconciliation, R6 data contracts, lifecycle/recovery, hosted editing, offline guidance and fresh Windows/Linux release acceptance; no subsystem checkpoint constitutes release completion.
 
 Meaningful progress now includes verified drag and typed-port authoring, accepted editable routing with native save/reopen, group movement and minimum-size evidence, and tested source-bundle/nested-writeback foundations with independent limitations exposed. Production source and direct behavior usability remain open engineering tasks; feature counts alone do not establish completion.

+Current user-directed drawing evidence: palette creation and draggable per-placement port anchors passed scoped native Windows trials with Save/reopen; full485 Windows and488 Linux workspace suites passed before final pointer-release and hover refinements. Fresh independent review exposed post-release motion turning clicks into edits, nearest-port mispicking at overview zoom, and missing target identity feedback. The first two have production regressions and fixes; named owner/alias hover details and source-preserving pan are implemented, with final native acceptance pending. See release-port-drawing.md. The preceding goal turn made concrete progress through implementation, saved source/SVG artifacts, actual runtime verification and reproduced findings; it was not a wait or no-progress turn. Direct behavior and the broader release requirements remain active.
