# Accepted-snapshot alias transaction experiment
Codex-9e8r6t `/root`, 2026-09-11; [issue 9](http://217.177.34.108:3000/sorokin.oleg.edu/ARCADIA-Studio/issues/9).
The actual copied production `Document::execute(SetAlias)` took **581.467,
426.723 and 449.493 ms** in three Windows debug samples. Complete expected
model/source, UUIDs, Undo/Redo, save state and all 37 physical fixture files
were checked. The fixture has **30 Arcadia sources and 7 supporting files**.
This is a completed experiment, distinct from the historical preparation status
retained in [raw/README.md](raw/README.md) and [raw/inputs.json](raw/inputs.json).
The [evaluation](evaluation.md) explains the measured phases, alternatives and
proposed transaction safeguards. No prepared-transaction implementation or UI
responsiveness is verified here. Three uncontrolled debug observations do not
establish a latency distribution, optimized-build performance or scaling.
The exact copied Document SHA256 is
`2ecc2cd496d4a83fd7a32b9dc68e49f0f1cb31a06263dfd6939b4764da5b73e2`.
The probe binds actual core artifacts from the successful GUIv3 build at
`eeeaa1262748800c4c9aaa1eca79a7de96757358`, with correction inputs4 unchanged.
Later repair save-baseline changes are outside this experiment's source scope.
The historical CLI supplied a separately preserved source expectation; its
whole-process timing was not substituted for Document execution time.
Raw results are in [accepted-snapshot-01](raw/runs/accepted-snapshot-01/result.json),
including command/status records, compiler and Cargo bindings, fingerprints,
all timing samples and separate stdout/stderr. The probe binary is identified
by [receipt](probe-binary-identity.json) and omitted from Git. The original
helpers retain their original workspace paths and are evidence, not an
instruction to run them from this archive.
[Manifest](manifest.json): **64 payloads / 748,617 bytes**, SHA256
`bc9775541677f94e9c88cb3969cdb240bd8125ff0705ece08239d7935da8bf2c`.
Original payload bytes are preserved with local Git text conversion disabled.
The first archive helper rejected a mistyped evaluation hash before creating
the destination; fresh file readback corrected the literal. Both helper versions
are retained. The experiment itself was not rerun or changed.
