Independent review — native child continuation 865483b

Scoped result: no material archive/evidence finding. The archive supports actual OA reopen + Save and SA first child, sibling, grandchild, each Undo/Save and Redo/Save, followed by reopen + Save, for the old source 865483b4c6 / packaged GUI BF9C2E618D4A4AC55E6A7EBB3738736659FC35A6465522C7B5AB975238938808. This is not native acceptance of a57c334 or a complete release gate.

Independent readback

• Rehashed all 111 archived payloads AND all 111 original paths against manifest size/SHA256: zero discrepancies; 3,762,865 payload bytes.
• Complete archive inventory is 115 files / 3,902,196 bytes. Exactly four files are outside the payload manifest: README.md, manifest.json, verification.json, readback.json; no unexpected extra file.
• All 16 raw status receipts are terminal exit 0, have completion timestamps, empty stderr and exact corresponding log stdout. Seven checks and nine compares; four OA receipts include the intentionally excluded file-only pair, twelve SA receipts cover baseline, three creation stages, six Undo/Redo comparisons and final reopen checks.
• Independently recomputed all nine complete physical-directory comparisons: zero mismatch. Checked all twelve adjacent checkpoint receipts against their complete file counts and per-file sizes/hashes. Reconciled readback entries with the manifest and verified its manifest hash.
• Rehashed all three original OA carriers against the prior committed OA archive files: exact equality. The confirmed OA snapshot matches the original OA grandchild two-file carrier (5,671 bytes), not a newly self-defined expectation.
• Inspected stage receipt arguments: SA stage 2 pins original first; stage 3 and reopened stage 3 pin original first and second. OA confirmed stage 3 pins original OA first and second. No redo/reopen output substitutes for these original identity carriers.
• Read the SA authored records across original stages: first e9348d74-3ae1-4bd4-8528-f72741b37031 and node f22603cf-d1f4-46df-80bb-a0f4e7032793 persist; sibling e2151fb4-287d-452c-995e-c742eff5e9fc, node 340cc7cb-4b20-4615-ab7e-fc1c55f51792 and allocation 92debc9e-6247-4b0d-8750-ccf93db8bec1 persist. Grandchild ef40c66e-cb3e-4740-a916-d43cb45a1b60 receives the original allocation ...0014, preserving performer source, Unicode rationale and artifact owner/revision. Original first position remains 108,188; sibling moves 108,298 to 108,394; grandchild is 132,252. Final SA source hash is E4124896FD3AAC851FC322280BC40E0F88527A8D4E18542234CC21B381F12E13; complete reopened carrier is 3,827 bytes.

Decisive screenshot review

Viewed only existing images 28,32,33,38,45,52,54,56,59,60 through view_image. Image 28 explicitly says Working… despite All changes saved. Thus historical child-oa-reopened-1948 passes prove disk data only, and misleading filename 25 is not promoted to reopen evidence. Images 32/33 explicitly show Source project opened / All source files saved, with OA nested geometry and 7 objects / 6 links. Images 38/45/52 show saved SA first/sibling/grandchild with expected identities, parent/performer properties and 3/4/5 objects; 54/56 show saved grandchild Undo/Redo topology and 4/5 objects. Images 59/60 explicitly show Source project opened / All source files saved with SA nested geometry and 5 objects / 2 links. Together with the closed original-carrier receipts, these support the claimed continuation. Root's action transcription supplies the individual input sequence; this review did not replay it.

Limits: no oracle/compiler execution, GUI input, Git, network or Linux activity; no archive mutation. Complete-directory equality refers to closed snapshot/carrier directories, not the excluded live working directories or arbitrary files outside them. Stage0 is a historical receipt against the then-unmodified working path; its current live state is not retroactively checked. Typed semantic correctness relies on the already-reviewed contract and preserved execution receipts, with direct source/identity inspection here; a new independent parser was not built. Screenshots do not establish backend failure causes or new canvas behavior. Remaining header typography, contextual-source, Home/Guide/normal-close and new canvas native gates remain pending as documented.
