GUI5657 source-child recovery and cancellation

Codex-9e8r6t /root/release_audit, 2026-09-11. This archive preserves only root's frozen initial/recovery Lifeline runs and cancellation checkpoint. Direct Create, history, Chain and Machine acceptance are excluded.

The 24 raw copies retain their exact original bytes. verification.json maps each archived relative path to its original repository-relative path, length and SHA256. manifest.json hashes every other archive file and excludes itself. No profile/work/cancelled-copy duplication, binary, future run directory or private package is included.

Container-format discrepancy retained transparently: the three screenshots have original .png filenames but their file signatures and image decoder identify JPEG payloads. They display correctly. No re-encoding or renaming was performed; checksums bind the actual captured bytes. Dimensions are 1102×732 (minimum), 2245×1232 (wide) and 1442×932 (cancelled Save).

Original records are under .local/native-qa/contextual-source-20260911-v2: preflight.json, Lifeline runs/initial and runs/recovery, the four recovery-evidence before/after records, cancelled result/log and the two checkpoint-cancelled source files. Exact preparation/check/launch helper sources from .local/native-qa are preserved under methods/. They describe the executed method; their path discovery and mutation logic assumes the original private location. Do not run the archived copies in place.

Independent frozen-record checks

• Both recovery snapshots' complete accepted source bundle equals the independent two-file fixture at harness/fixtures/staged-source-authoring/base. Their entire workspace objects and authored behavior objects are exactly equal to each other. Workspace applied state, both original/current file versions and reachable paths agree with that baseline.
• Parent name Retain parent 雨 and source name Retain source Δ retain their surrounding spaces and distinct text. The child remains explicit Activity / OA / semantic layer root, and is editing rather than staged.
• The restored snapshot has origin null, preserving recovered-copy isolation. The new recovery record ID/time may differ; those wrapper fields are not misrepresented as whole-record equality.
• All four reserved UUIDs remain identical and distinct version-4 IDs: invocation d35280aa-09ba-4281-a32e-2080f9af7161, source 188cc882-b656-4d76-bb46-33ffe6d2ab22, child token c2a3e470-46cb-427a-8390-cbbc57f1bc01, consumer identity 6c15e882-e523-4793-b715-d2e9bfd1ff38.
• The saved cancelled checkpoint contains exactly notes.arcadia and project.arcadia, byte-identical to the independent baseline and bound by cancelled-result.json. The unchanged core oracle's recorded same command exited 0 and reports exact model/identity, two reachable sources and two exact disk files. This archiver independently rechecked bytes and records; it did not rerun that oracle.

The preflight manifest includes previously checked Machine input preparation; retaining its exact bytes does not establish any new Machine workflow result. The launch manifests bind GUI SHA256 5657BAB5C841939B66F901EFE6C0FFB2D7CBBE8CC5F111A0CA3DE8073D3846CE and the verified runtime DLL. Initial PID 5184 was deliberately stopped only after the exact completed recovery checkpoint; recovery PID 7928 closed normally via root's Alt+F4 and was observed absent. Its normal-close record has no invented process exit code. Both runs' actual stdout/stderr are empty payloads, retained as such.

Native observations and limits

Root observed the complete Name, determined Activity heading, explicit root parent and pinned Back/Use at the normal-panel 1100×700 client size. The archived minimum screenshot independently shows those controls without the earlier clipped Name; its frame-inclusive image is 1102×732. Root's maximize/restore trial retained raw names. After recovery, Escape dismissed only the child; reopening showed a blank new child; temporary source Use followed by parent Cancel left no model adoption. Ctrl+Z reported Nothing to undo, and Save As to the separate cancelled-copy yielded the exact baseline oracle result above. These event observations belong to root's native trial, not to a new UI run by this archiver.

This slice does not prove direct source+consumer Create, Undo/Redo after an accepted transaction, Machine recovery or any Linux behavior. Root continues those separately. The earlier GUI52 native evidence and current GUI5657 cancellation/recovery evidence are distinct.

The directory has a narrow -text attribute rule to preserve measured bytes. Its five .log files remain affected by the repository's global *.log ignore rule; root must explicitly include them when staging. Root owns native reporting, ledgers and publication. No compiler, native input, WSL or Git/index mutation was performed by this archiver.
