Current accepted return208 by @AndreBaltazar8 verifies @maxime-fleury's repair for the shipped finite run; it does not claim a twin-prime theorem. The repair keeps the numerical summary in stdout and explicitly writes elapsed-time diagnostics to stderr. This assignment inspected source and prior art only, with scientific CPU0 and no producer, census or checker rerun.\n\n## Convention and exact source correspondence\n\nThe convention is explicit per-call output-stream selection and separation of numerical output from diagnostics. Python's current print(file=...) API is the closest published statement. A mathematical theorem about twin-candidate gaps is a different object from this accepted repair claim.\n\nThe complete original g2check.py (SHA-256 3a7161d9ffd11d700d5a7664a87d2ca66cd8cd410e0dde878478207345b3fa03), repaired g2check.py (ea51f73a04a0962064880ac95c98ad3def121ababac6b66ef51bd9eb2aa793f0,920bytes), patch (1c131f401823d0aabd51e022e601c2946686fc1898ae6a90a0c49c78d9f1f48d,438bytes) and archived stdout (f28c373f8c027a414932c145f65a65623a7327335b83271d7d9be504c9561173,493bytes) were fetched, SHA-checked and read completely. The only patch replaces original line23's combined numeric/time print with repaired line23's numeric print and line24's timing print using file=sys.stderr. sys is already imported at5. No local print override or stream reassignment appears in the complete source.\n\nThe retained arithmetic expressions, loop, cutoff and numerical formatting are unchanged by the patch. Under ordinary Python bindings, the numeric call defaults to sys.stdout and the second call targets sys.stderr. This establishes source/API correspondence. It does not establish arbitrary runtime environments, stream delivery/order, encoding-independent bytes, or the numerical calculation's correctness.\n\n## Known-match audit row\n\n| Object | Primary owner, venue and year | Exact location inspected | Coverage and difference |\n|---|---|---|---|\n| Python3 per-call file=sys.stderr print | Georg Brandl, Python Enhancement Proposal3105, created November19,2006, Python3.0 | Specification, HTML39-56, explicit stderr example; metadata3-12 | Direct known API match. The proposal supplies stream selection, not a theorem about repeated program bytes. |\n| Earlier explicit target without globally replacing stdout | Barry Warsaw, PEP214, created July24,2000, Python2.0 | Introduction/Proposal26-54 and Justification55-73 | Historical predecessor. Its Python2 print statement syntax is not the repaired Python3 function syntax. |\n| Current print default/file semantics | Python Software Foundation/core developers, Python3.14.7 documentation, retrieved September14,2026 | print HTML790-799 | file omitted/None selects stdout; explicit file selects a text stream. Documentation edition is not a claimed runtime version for208. |\n| Standard-stream definitions and caveats | Python Software Foundation/core developers, Python3.14.7 documentation | sys HTML1152-1184 | Confirms stdout/stderr roles; streams can be replaced/absent and buffering/encoding vary. |\n\nPrimary links: [PEP3105](https://peps.python.org/pep-3105/), [PEP214](https://peps.python.org/pep-0214/), [print reference](https://docs.python.org/3.14/builtins/functions.html#print), [sys streams](https://docs.python.org/3.14/library/sys.html#sys.stderr). These are standards/API sections, so journal theorem/equation/page numbers do not apply. PEP3105 metadata and its complete short specification were read, not its mailing-list sources or CPython historical implementation. PEP214's named sections were read; ancillary alternatives/reference patch were not audited.\n\n## What remains attributable to208\n\nReturn208 reports two corrected fresh-directory runs with byte-identical stdout, and an original run matching after removing trailing timing fields. It reports nine rows throughp=23, cutoff period223092870, each census matching its expected field, all three exits zero, and correction of an initially mistaken eight-row expectation. The current archived output contains those nine rows. These are existing finite execution observations, not new executions here. Its current report is byte-identical to the job1216 and1230 reading snapshots. I preserve its explicit refusal to claim reproduction of message800's earlier full-output hash.\n\nThe API result explains why a variable elapsed-time suffix can be excluded from the numerical stream. It does not replace those finite byte comparisons or independently prove their observed numbers. Changed source identity, a changed numerical expression/field, local stream redirection or timing still included in the numeric print would falsify this source-match conclusion. None appears in the fetched source; no broader portability or mathematical claim is inferred.\n\nI reused the prior exact standard-stream search in returns524/529 for the adjacent return211 repair, while inspecting208's distinct source and original patch afresh. Fresh targeted Python/POSIX searches found the same convention plus the original Python PEPs. Open Group primary search snippets support the conventional diagnostic-stream vocabulary, but repeated direct page opens failed; no unread POSIX body is treated as evidence for the Python API.\n\nSEARCH-CONVENTIONS' owning-vocabulary rule was read. IMPORT-MAP's Scope and section0 grade foreign mathematics and exclude vocabulary-only imports. This software correspondence is not a mathematical import that opens a gap/exponent route, so the row above is an audit record in this return rather than a served IMPORT-MAP revision.
