METHODS
ChatGPT disclosed an earlier English interpretation visible in its conversation.
It is not a blinded semantic replication. Its new reported implementation
reruns successfully with standard-library Python: all 74 delivered tests and
four additional lower-stage rejection probes pass. Fourteen of fifteen final
result files reproduce exactly on Windows; the checksum manifest alone uses
CRLF instead of LF, with identical hash/name entries.

The organizer explicitly confirmed Claude's completely fresh conversation,
given only the PNG and instructions, with no prior USL context. Its returned
data are correct. Its shorter prose preserves the central invitation and most
key distinctions; complete qualifications remain in the exact recovered source.

CLAUDE CODE AUDIT
The unmodified exported script stops at a missing reconstructed.txt file.
A documented write of its own newly expanded bytes permits source-stage
reproduction: 108 true logged booleans and 15,040 zero RS syndromes on the intact
image. The delivered script stops before its reported final concept-token,
alias and selected-pin joins and often logs failed checks without stopping.
Our separate audit verifies the actual returned bindings and context.

Thirteen component probes: 6 invalid inputs unflagged, 4 diagnosed but execution
continues, 3 integer controls raise. Examples include unchecked trailing zlib
data, an unjoined shifted concept-token span, and continued payload export
after an RS parity failure. These are scoped stage probes, not altered images
passing the published original-file hash. Counts use different units and are
not comparative model scores.

CONCLUSION
Exact RGB24 recovery succeeded for the frozen message. Claude adds one
organizer-reported fresh-context interpretation. ChatGPT provides a complete
reproducible receiver for this intact E01 recipe. Claude's correct output is
stronger evidence than the completeness of its particular exported validator.

This is one code-assisted expression, not a population success rate, optical
test, English-independent grammar, or demonstration of identical judgment.
The historical dictionary and grammar travel inside the packet. Integrity
hashes do not authenticate authorship or certify semantic truth.

The research archive includes original returns, frozen inputs and sender key,
both readings, local audit additions, probes and reproduction instructions.
For a fresh receiving exercise use only the two-file receiver kit.
