Verified branch checkpoint — 2026-09-11

This checkpoint describes Codex-956atf's contribution, not a combined release. PROJECT_GOAL.md remains authoritative; the complete OA/SA release is unfinished. Current user guidance emphasizes close study of Capella semantics and practical, ergonomic engineering workflows.

Linux/WSL builds and all checks are paused until the user explicitly reports networking resolved. No guest diagnosis, restart or cache transfer is active. Completed Linux evidence remains historical; the VPN remains untouched.

Verified implementation

Previous native acceptance uses source 3c9e6eeb64 on codex/behavior-authoring-20260910. It passes 720/720 Windows desktop tests and strict all-target desktop Clippy. It includes direct scenario/process authoring, parent-focus and editing-session/chooser corrections, and boxed workflow events. Evidence checkpoint e7491fb preserves exact logs. Instruction-only merge828c50c retains the incoming user-owned AGENTS/PROJECT_GOAL files unchanged. The actual remote default branch main was checked after that merge; its current guidance was read without overwriting the user's local specification.

The matching GUI built warning-free and passed recovered SA State, clicked Reuse, and ALT Fragment creation with exact Save/Undo/Redo and final native Open/Save at the 1100x700 client minimum. The whole Project, all identities and both source files match every required history checkpoint. The native session is closed.

• Windows regression/lint evidence
• Previous native SA evidence
• Earlier native OA/SA Action evidence, scoped to 80cf197
• Scenario oracle and reproducible procedure

Isolated contributions and material limits

Core candidate 847b1caa7e is on the separate codex/analysis-core-956atf-20260911 publication branch. Windows execution passes the 128 KiB-thread lifecycle subprocess, all 6 codec tests, 28 analysis tests, 26 numeric tests and strict all-target core Clippy. These counts are separate scopes; the subprocess driver is included in the 6. Production DEPTH_128_VALIDATED remains false. Legacy/migration/save integration, release memory measurements and complete source8/transport/evaluator acceptance remain open. Windows codec evidence.

The integrated R123 canvas at ff0175488a passes 729/729 desktop tests with a warning-free compiler, including the 17 new mounted cases and preserved parent-focus/session gates. The guide refresh at 82fd0ac passes 3 guide tests. Strict Clippy at abffa4b identifies four obsolete canvas variants; no post-cleanup or current GUI pass is included in this checkpoint. Closed gate and exact evidence, independent union review. Parent/child native focus, complete direct manipulation, persistent process placement/lanes and coherent B4/source integration remain unverified here.

Complete quantities/calculations/constraints, maintained libraries, graphical/ source/REST parity, transitions and engineering-task usability, aligned reST/help, optimized packages and final independent acceptance remain required. Finite prototypes and published previews are intermediate results.

Authoritative records

• Project overview and historical coordination
• Direct process/scenario canvas work
• Activity allocation drag
• Analysis, codec and source/API integration
• Maintained reusable libraries

• Historical Linux gate before deferral

The duplicated live ledgers were migrated once into Gitea comment412. Their complete original bytes and manifest preserve historical assumptions, decisions, experiments, limitations and links. Links inside the archived documents retain their original harness/ base. Do not maintain live plans in this checkpoint or repeat that migration.
