 | Milestone | Work and acceptance | Dependency/current limit |
 | --- | --- | --- |
-| 1. Reliable direct authoring | Finish cold compilation and meaningful regressions; integrate compact named architecture/behavior creation and scenario workspace. Exercise actual minimum/wide native creation, allocation, editing, rejection, cancellation and history without implicit draft application or placement drift. | Root owns this host's Cargo/native lease. External host owns scenario layout/B3/local creation/palette; integrate coherent checkpoints first. No current local Rust/native Studio pass. |
-| 2. Coherent process/scenario work | Interactive ordered/explicit process editing; clicked root/nested scenario insertion; exact reuse bindings and caller return; measured canvas/zoom/scroll; visible scoped Create/Delete lifetimes. Validate model/source/identity and no unintended edit during navigation, including stale/deleted/retargeted references and recovery. | B1/B2/B3 adapters are source-integrated; B3 has a known externally owned correction. B4 is cfg(test) projection only, awaiting Scene integration. The independent oracle compiled/self-checked and its generated baseline passed; use it for native checkpoints. |
+| 1. Reliable direct authoring | Exercise actual minimum/wide native creation, allocation, editing, rejection, cancellation and history without implicit draft application or placement drift. Integrate compact named behavior creation after its coherent external gate. | Full local desktop suite passes 642/642 at80cf197; GUI build/native and strict lint remain open. Workspace/B3/palette/recovery/packages are imported. Root owns this host's Cargo/native lease. |

B4 is cfg(test) projection only; real lifetime extents, branch-local activation clipping, incomplete lanes and self-arrow endpoints require integration. Use the independently self-checked oracle for native checkpoints. |
 | 3. Precise engineering analysis | Compare owned properties, analysis contexts and existing-data/external alternatives; settle quantity kind/unit/value, numerical policy, calculation/binding and Boolean/error/unknown semantics through falsifying examples. Implement mixed-unit budgets and reusable calculation/constraint definitions with full UI/source/REST parity and exact history/recovery. | New requirement audit confirms absence. Maximum-reasoning proposal tracks precede root synthesis and independent criticism; no semantic contract is ratified yet. Strings are not evaluation. |
 | 4. Maintained reusable libraries | Compare package/definition/instance alternatives. Establish pinned identity/version/dependency closure, local edits, import bindings, detach and explicit three-way updates. Demonstrate two projects, two independent instances, offline reopen, conflicting updates and stable unaffected identities. | Coordinate with milestone 3 definition references and migration. Same-project includes/reuse do not satisfy maintained cross-project libraries. No package contract implemented yet. |
-| 5. Understandable complete engineering tasks | Close teaching, OA↔SA transition/reconciliation, typed state/data/interface, artifact, saved-view and hosted workflows. Replace concrete long homogeneous selectors with contextual/searchable bounded choices; verify representative large models, keyboard access, minimum sizes and failure/recovery. Keep offline guide and exact worked examples aligned. | Existing implementations and historical evidence are a coverage starting point. Reassess against current goal instead of reviving stale absence claims or carrying old scope exclusions forward. |

 ## Immediate execution sequence
 
-1. Observe the existing one-job desktop build to completion; preserve failures and
-   fix causes. Run focused corrected cases, then proportionate full gates and GUI.
+1. Finish the current GUI build and format/strict Clippy checks, then run native
+   engineering tasks. The current 642-test desktop suite has passed; rerun for new
+   code or unresolved failures, not as a substitute for runtime evaluation.
 2. Exchange exact verified commits with the separate host, preserving its workspace
    ownership. Do not merge the bundle-transfer branch or assume remote publication.
 3. Use the self-checked [scenario oracle](scenario-authoring-contract.rs), follow
    its [native procedure](fixtures/scenario-authoring/README.md), and compare exact
    whole snapshots for Undo/Redo/reopen at minimum/wide sizes.
-4. Synthesize the [requirement delta](release-requirements-delta-20260910.md) and
-   independent semantic proposals; subject materially different candidates to
-   concrete numerical, identity, migration and engineering-workflow falsifiers.
+4. Resolve the paired semantic criticism with concrete text-only package normalization,
+   cosmetic revision/type compatibility, subjectless analysis closure, OA/SA mounted
+   data transitions, baseline-versus-case maintenance and closed numeric algebra
+   experiments. Select coherent contracts before production metamodel expansion.
 5. Update current ledgers and durable decisions when evidence changes the plan.
    Reassess unresolved assumptions before expanding downstream implementation.
