First release — current engineering state

Objective and current phase

The first-release goal remains active and incomplete: a Rust/Iced OA and SA/System Architecture tool for system engineers with equivalent graphical, textual and REST semantics, hierarchical diagrams and typed ports, modular source projects, artifact traceability, direct behavior editing, offline help, and Windows/Linux release evidence. The authoritative objective is attachment 07aee762-7d27-4cbe-81c3-2e82c7170711/goal-objective.md, fully read on 2026-09-05. PLAN.md, TASK_LEDGER.md and release-semantics-audit.md retain the broader scope.

The editable connection-routing milestone is accepted at 23535b4 with viewport follow-up 366ce44. Per-diagram authoring, obstacle-aware geometry, typed/nested workshop movement, save/reopen, SVG and minimum-size gestures are verified. Commit 65fa9ab resolved all six reproduced default SA label-overlap pairs. Fresh correctness and native UI review found no unresolved material routing finding; root also verified the actual Linux application and the viewport follow-up. The broader first release remains incomplete; production text authoring is active. See release-routing-verification.md and release-routing-linux.md for exact evidence and limitations. Root alone operates native applications.

Completed foundations

• Branch codex/release1-engineering; baseline 93ba83d, hierarchy c7101b9, drag selection 2ef16dc, typed core/schema 3 merge 757ab88, alias and batch lifecycle corrections e41b8de.
• Typed desktop integration fa096ce provides contextual function/component ports, FE endpoint and exchange-item choices, generation, resolution, split and synchronization with semantic previews. Legacy migration, Standard/Flow distinctions and independent orientation are retained. Independent findings and native-discovered no-op synchronization and SA-only initial-perspective defects were fixed.
• Native typed-port trials created real function endpoints and exchanges, supplementary output/items, and a Standard component implementation with two port allocations and an exchange allocation. Undo/redo and save passed with zero model checks. Reviewed reopen entered SA correctly; unchanged synchronization disabled Apply. The long-reference review modal was inspected at 1440×900 and 1100×700. Evidence and fixtures are under D:/CodexBuilds/Capella2-release1-01a06e2e/ui-typed-ports and ui-typed-ports-reviewed.
• Source bundle foundation 06b3384 and token-preserving updater dbc8971 passed 160 core tests, including 30 source-project tests, and strict core Clippy at that checkpoint. This is a pure core foundation; production editor, filesystem Save All/conflict handling and REST bundles remain to be integrated.
• Isolated source authoring comparison c5788fc and nested writeback experiment 2dd17aa passed 23 experiment tests and strict Clippy. An independent executable probe at D:/CodexBuilds/Capella2-source-writeback-independent/probe.log reproduced positional list-comment misattachment after item reorder, rejection of a valid description edit on port shorthand, and unsupported occurrence deletion. The same comment-reorder probe retained attachment in the production updater. Complete model equality alone does not protect comment meaning. Extend the production parser/span index and shared updater for selected nesting/shorthand constructs; do not copy the experiment into a parallel production parser/writer. Freeze comment ownership, exact source Undo and full edit/delete support before adoption. experiments/source-authoring/WRITEBACK.md retains the bounded evidence; production syntax is not yet adopted.
• R1 process topology, R2 mission/capability, R4 scenarios and R5 events/states are implemented at the semantic/form level. Full native authoring acceptance and direct behavior canvas gestures remain required; release-state-gesture-design.md records the proposed first vertical slice.

Routing implementation and verification

• 4e5a88d: per-diagram EdgeRoute pins and label placement, atomic set/remove commands, validation, delete/reidentify cleanup, compatible empty defaults, group movement and layout translation. Routes refer to existing relation/trace IDs and do not duplicate semantic identity.
• a7c6f96: equivalent source, source-project update, JSON and REST behavior, located validation, OpenAPI and reST contracts.
• 68b1eff: shared deterministic orthogonal routing and geometry for typed ports, nested obstacles, labels, bounds and collapse suspension. Desktop draw, hit testing, gesture previews, Fit and SVG use this geometry.
• 30c7db1: label-only edits preserve the settled polyline and warnings; single-edge previews retain settled per-edge routing budgets. 65fa9ab adds stable bounded automatic label placement, reducing the workshop's six reproduced label-overlap pairs to zero. All 18 geometry tests, strict core Clippy and fresh independent correctness review passed.
• 23535b4: accepted desktop route authoring, shared geometry integration, route/label controls, guarded atomic gestures and release-cursor correction. Final independent native review captured clear minimum-size controls with the authored bend/label and the readable lower SA label band. Its full SA view was partly occluded; root's earlier full SA captures provide the complete-view evidence.
• Locked workspace tests passed with 196 core, 103 desktop and 22 server tests before the last geometry regressions were added. Final follow-up passed 104 desktop tests, strict full-workspace Clippy and desktop/server builds (routing-final-* logs). Independent review also passed four focused desktop tests for the final release-cursor correction, which commits fast drags despite coalesced motion events. Earlier follow-up passed the 1500-edge reproducer and six external preview/commit fixtures. Exact scopes are in release-routing-verification.md; a final full-workspace test rerun after all later edits is not claimed.
• Independent stress measurements on 100 nodes/150 edges with eight pins per edge: maximum single-edge preview 16.4 ms debug and 2.4 ms release; settled full solve 863 ms debug and 119 ms release. The optimized settled result slightly exceeds the initial 100 ms target; this remains a measured performance limitation, not a claim that the target passed.
• Routing workshop 4b8545d adds deterministic, validated .arcadia and JSON examples plus a reproducible Rust generator. OA and SA architecture views contain three participants and nested work groups; SA includes real functional/component ports, Standard and Flow exchanges, and an internal System exchange for group-movement testing. Generation, source/JSON equality and zero semantic/routing issues were verified.

Native checkpoint and evidence boundaries

The reviewed executable at ui-routing-reviewed/arcadia-studio.exe has SHA256 6DAD490D75F2A67A79A0804F33192EF62A3DCBEA92F5EEDA8EA47788D12273B8. Root performed default-size OA edge selection without canvas movement, segment drag without a retracing spur, separate label drag with unchanged polyline, displaced-label selection, existing-bend drag, Undo/Redo, Remove bend, Reset routing, and undo restoration. Folding an endpoint container used an automatic promoted edge and disabled route editing; expansion restored the authored pin and label. Model checks remained zero.

Native Save As and SVG export produced ui-routing-reviewed/routing-authoring-ui.arcadia (33,548 bytes) and .svg (2,564 bytes). The source contains the authored waypoint and label offset. Root then launched ui-routing-final/arcadia-studio.exe, SHA256 5558CC203E9DAFED3D0BCA1C40B5E4BDE426F00F8BC37DCD9B33A7338ADD5615, containing 30c7db1, duplicate fold-notice cleanup and export-dialog copy changes. Native Open reopened the saved source with “All changes saved”, 41 objects, 25 links and zero checks; the bend remained visible and the detached label selected the same edge. Root rendered the actual exported SVG to PNG with Sharp and visually verified the authored detour, label, bounds and nesting.

The workshop loaded with 12 cards/seven links in OA and 12 cards/12 links in SA; the full model reported 75 objects, 61 links and zero checks. Root dragged the internal Incident decision line to create a pin. Moving one function left that pin fixed; moving the whole System by snapped delta (-20, +40) translated the pin by the same amount. A single Undo/Redo restored both placement and pin state. The typed trial was saved to ui-routing-final/typed-routing-authoring-ui.arcadia (66,598 bytes); folding and expanding the System restored the route and the UI reported all changes saved.

On ui-routing-labels/arcadia-studio.exe, SHA256 4D4C8163EA2A81F2D9A241921571BE3118AE57ECD2987E7088878CBCA9F50536, native reopen of that typed trial retained the SA custom pin and separated labels. Dragging an automatically displaced label was continuous and Undo worked. This closes the label finding together with the geometry tests and independent review.

The accepted executable at ui-routing-accepted/arcadia-studio.exe has SHA256 E9B662788CC3979F8E883299CAF9B16917498D6F0DEAB62E02D9A6CE5C18AFB2. At 1100×700 (captured frame 1102×732), a short 29-pixel bend drag and approximately 18-pixel label drag succeeded on the first attempt. The canvas and controls remained stable; SVG dialog copy fitted. Native export produced minimum-routing-ui.svg; its PNG rendering was visually inspected for correct route, label and nesting. This later successful trial supersedes the earlier width-only resize attempt. The accepted minimum-size window retains an unsaved demo with those two gestures; preserve it before switching models. The saved typed workshop remains the durable SA fixture.

Unexpected concurrent arrangement/view changes were separately preserved to ui-routing-final/workshop-arrangement-preserved.arcadia (66,434 bytes). A prior icon-only capture did not establish an application failure; subsequent full native captures succeeded. Obtain fresh inventory before further input instead of relying on historical window IDs.

Original Capella was operated in a disposable workspace. Native creation demonstrated real FE/function ports and explicit component-port allocation. Format > Line Style > Oblique followed by a segment drag created an actual bend without changing its Audio Signal/FOP1/FIP1 endpoints. A rectilinear-corner attempt did not move. See release-capella-workflow-benchmark.md; the reference sample was not saved.

Earlier Studio windows disappeared during concurrent work. Fresh inventory confirmed absence and no matching application-crash event was observed; the earlier unsaved routing trial was not recovered. It is superseded by the explicitly saved reviewed fixture, not retroactively claimed as recovered.

Exact next actions

1. Implement release-source-integration.md. Core prepare_command is committed in 41d7963; 198 core tests passed after extraction. The new desktop Document module passed eight external-harness tests and strict Clippy for exact accepted history, single identity creation, failed writeback, delayed saved baselines and missing-ID dirtiness. It is not yet integrated or committed. Agent source_integration_map owns desktop Document/workspace/app/views/tests integration; source_filesystem owns core disk IO/tests and the narrow same-file dependency/export change; source_document_review independently reviews the Document boundary. Root owns integration, documentation and native QA. Then extend the production parser/updater for the selected syntax direction and REST bundles; do not promote the bounded experiment unchanged.
2. Linux routing acceptance is complete. Independent verification passed all 324 workspace tests, strict Clippy, formatting and optimized desktop/server builds at 23535b4. Root's actual Linux/WSLg bend, label, Undo/Redo, Save and reopen passed. That run exposed a dialog-induced viewport recenter, fixed in 366ce44: all 105 Windows desktop tests and strict desktop Clippy passed, Windows/Linux rebuilds passed, and root's rebuilt Linux native trial preserved the viewport throughout Save. release-routing-linux.md records exact scopes/hashes; final saved fixture is ui-routing-viewport/linux-routing.arcadia (33,546 bytes). The Linux test window was closed normally after saving. No full 325-test Linux invocation is claimed.
3. Implement direct state/scenario/process gestures, R3 semantic drift and reviewed reconciliation, R6 data contracts, persistent coverage/filters, Home/recent/recovery, hosted ETag workflows, navigable offline guidance and normative reST/API completion. These are required release work, not non-blocking limitations of a finished release.
4. Run fresh requirements, correctness, native UI/UX and architecture reviews for the complete release; address material findings. Verify current Windows/Linux/MSRV builds, runtime workflows, documentation, packages and checksums before completion.

Environment and reproducibility

Windows Rust 1.98.1; CARGO_TARGET_DIR=D:/CodexBuilds/Capella2-01a06e2e. Release logs and native fixtures are under D:/CodexBuilds/Capella2-release1-01a06e2e. Use cargo test --locked --workspace, cargo clippy --locked --workspace --all-targets -- -D warnings, and cargo build --locked -p oa-desktop -p oa-server. Generate the routing example with cargo run --locked -p oa-core --example routing_workshop; historical migration goldens stay frozen.

Prior WSL Ubuntu 24.04 evidence is in verification-v2-linux.md; current routing automated/build evidence is in release-routing-linux.md. The Linux routing application was launched with the documented Mesa Vulkan software adapter and operated through Computer Use. Full first-release Linux runtime/package acceptance is still required after remaining implementation. There is no current disk blocker. Do not retry the earlier rejected recursive target deletion. No usage reset or remote push is authorized.
