Assisted-by: OpenAI Codex:model version unavailable
* Consolidate equivalent AST literal location cases
Replace the six-way literal-only optimizer matrix with one optimized-AST round-trip, preserving all assertions. Keep the distinct normalized-range identity, explicit Pass provenance, and synthetic format-spec regressions.
Validation: all four appended location cases passed using the verified final-f6a RustPython binary with unchanged native sources. Ran normal pre-commit hooks; no Cargo build or full cyclic snippet suite.

* Reuse Ruff source locations in AST conversion
Replace redundant PySourceLocation, Row, and Column wrappers with the compiler-core re-export of Ruff SourceLocation. Use UTF-8 byte coordinates and retain the empty-source fallback. Share the normalized range conversion while preserving caller validation and signed semantic metadata.
Validation so far: independent source and boundary review, rustfmt, and git diff --check. Runtime validation follows after the shared build target is released.

* Preserve the first AST preprocessing location error
Share first-error recording between generated-node allocation and synthetic-pass coordinate overflow. Exercise both real compiler-state failure paths in both orders using one MAX_ID location entry.
Validation: focused compiler-state regression, strict codegen all-target Clippy, unchanged full-source seals, rustfmt, and normal pre-commit hooks. No interpreter runtime or broad suite rerun for this error-only change.

* Target Python 3.15 using the final upstream reference
Update active version and comparison configuration to Python 3.15.0. Preserve the alpha implementation status, actual bytecode format, and existing libraries pending separate migration. Align generated library-upgrade workflow pins without changing permissions or actions.

* Adapt essential snippet contracts to Python 3.15 final
Preserve existing coverage while following verified final behavior for script metadata, builtin signatures and loading, AST fixture construction, memoryview diagnostics, mmap search bounds, and struct format errors. The unchanged final comparator exposes the earlier expectations; focused native baseline failures establish the required implementation changes.

* Keep final-reference regression paths and remove expired sysconfig argument
Preserve reverse multiplication syntax and native exact overflow diagnostics. Accept the two source-proven CPython 3.15 specialization messages only in affected reverse str/bytes/tuple cases. Use an actually out-of-range Windows datetime errno fixture. Remove the sysconfig check_home argument at its existing canonical 3.15 removal test boundary.

* Keep README wording unchanged in Python 3.15 transition
Assisted-by: OpenAI Codex:model identifier unavailable
* Match Python 3.15 repetition specialization and keep universal tests
Use exact sequence-type guards and preserve generic fallback diagnostics. Validate both cold and warmed expressions without implementation-specific assertions. Reject stale CPython source checkouts and cross-version library caches.

* Enforce Python 3.15 AST constructor requirements
Reject retired missing-field and arbitrary-keyword forms while preserving defaults and explicit placeholders. Sync only matching final CPython constructor test hunks.

* Keep seeded Python ahead of its Windows DLL directory
Assisted-by: OpenAI Codex:model identifier unavailable
* Keep opcode metadata tied to the implemented bytecode format
The interpreter target and reference tests use Python 3.15.0, but the current Rust opcode enum retains the 3.14 bytecode format. Generate metadata from its matching source rather than importing unsupported instruction families.

* Align CSV, logarithm and decimal formatting with Python 3.15
Propagate dialect lookup errors except AttributeError, retry integer logarithms after float overflow, and update the decimal conversion diagnostic. Exercise the final reference contracts without implementation-specific branches.

* Bind the logarithm index result before borrowing its integer

* Align required canonical test expectations with Python 3.15
Take only demonstrated contract changes from CPython v3.15.0, d220409a13b77de7a6c30abe16ea90db01528edc: removed module __cached__, Struct format exception classes, and decimal-format diagnostic. Preserve unrelated tests and expectations.

* Track pending frozendict pickle support during the 3.15 transition
Keep the two existing frozendict pickle tests running as expected failures until #8951 supplies the builtin. Unexpected success will signal removal of these temporary markers.

* Support final Python 3.15 Windows negative timestamps
Use FILETIME for pre-epoch conversions and preserve precise Windows timestamp errors.
Assisted-by: OpenAI Codex:model identifier unavailable
* Derive historical Windows timezone offsets from wall time
FILETIME reports historical DST as unknown, so calculate the actual offset rather than selecting standard-time bias.

* Identify decimal formatting arguments in Python 3.15 errors
Track consumed positional arguments, including star width and precision, and preserve mapping key representations in decimal conversion diagnostics.

* Sync final Windows timestamp test expectations
Import only the final CPython platform-limit guards and mktime roundtrip expectation required by the existing Windows CI suite.

* Restore official Python setup for 3.15 final
Use the existing pinned setup-python action now that its official catalog supplies CPython 3.15.0. Remove the temporary standalone provisioning action and its sparse-checkout entry while retaining interpreter outputs and requested versions.
Assisted-by: OpenAI Codex:model identifier unavailable
* Align merged runtime contracts with Python 3.15 final
Restrict mappingproxy ordering, use final codec registry normalization, and prefer index conversion before float conversion for sleep. Retain universal Python assertions and import the matching final codec/time canonical test hunks plus the non-ASCII codec-name deprecation warning.
Upstream source: CPython d220409a13b77de7a6c30abe16ea90db01528edc. The existing codec normalization implementation and bytecode contract remain unchanged.

* Limit Windows launcher version check to its interpreter
Exclude only the CPython py.exe version-identity case from RustPython CI. The installed launcher reports its own final version, while RustPython correctly remains alpha. Preserve the other 45 launcher cases and all RustPython version assertions without modifying Lib.
