Public mixed source8 read API: Windows evidence

Final source bab6f96a5b on codex/analysis-public-read-956atf-20260925, based on ordinary compatibility source7b06b8e. Source and evidence are local-only, not an integrated release or a confirmed Gitea publication.

The selected contract exposes language::check_mixed_bundle(&SourceBundle, ProjectLimits). It validates complete explicit-ID mixed ordinary/typed source8 input and returns immutable model and located-warning views borrowing that input. It retains actual syntax, accounting and admission evidence. Existing ordinary editing APIs remain separate.

evidence.zip: 1,130,273 bytes, 151 members, SHA256 1c20b7bffdaee9b1139b0e922d4366f6ac739f8567040e8f4723dc19e3974656. manifest.json pins every member and its origin. Creation checked CRC, exact inventory and every unpacked member byte. The archive includes all 27 actual Cargo receipts, two CLI receipts and original inputs, captured launchers, relevant baseline records, contracts, source patches, independent oracles and reviews. It references the audited ordinary archive rather than duplicating it.

Verified result

• 299 core tests pass: all 298 previous names/outcomes plus one new constructor policy test. The focused constructor run also passes.
• Ten external integration tests pass against the normal library: complete independently authored OA/SA models, all located warnings, scoped identities, cross-file references, explicit-ID requirements, malformed input, include/path restrictions, limits, Unicode locations and unchanged source bytes.
• 65 existing integration tests pass: source_project33, identity_updates3, nested_updates12, source_files8, r3_migration5, selected checked_save3 and one exact source7 migration case. These rerun against the promoted production parser.
• Three documentation cases pass: actual usage and two compile-fail lifetime examples. The recorder's naming discrepancy is preserved and reconciled below.
• Strict core all-target Clippy passes. Format exits1 with the unchanged raw baseline SHA256 c1c6b12861c8117ce6ffc6d6742ebf92618aafb10160ec6f99d370ca72ebab2d; formatting is not reported as passing.
• The rebuilt ordinary CLI passes check ENTRY --json and rename-alias ENTRY team rescue_team --json. Exact cross-file preview text and unchanged complete Unicode/CRLF input inventory are checked; neither uses --write. These are ordinary CLI regression checks, not mixed CLI support.

All final gates bind this source and its 562 declared Git inputs. Core executable SHA256 is 01a051033bb53512a2747c2ef87e366e9b189c14df060d24284db437d39ff96a; CLI executable SHA256 is 10302f9a0c17e82b57ab6498e2d76c47d6f68388888855b89397660825caac5c. Executables are not duplicated in the evidence archive.

Preserved findings and independent readback

Initial ddf823a production compilation failed with E0063: a semantic-row Parser initializer still gated mixed: None under cfg(test). Source8555e41 removes that stale attribute. Its ten external tests pass, with two warnings. Final bab6f96 gates a test-only policy observer and removes a redundant test import; no model oracle, diagnostic expectation or semantic policy is weakened.

Rustdoc lists the two CheckedMixed examples without a suffix, but prints - compile fail in their execution names. All three tests and Cargo pass; the recorder rejects exact name equality. RUNTIME-REVIEW.md and the readback preserve that verdict and map only those two complete names at source lines36/50, with the positive example unchanged. No generic normalization or runtime rerun was used.

SOURCE-REVIEW.md, LAUNCHER-REVIEW.md, RUNTIME-PLAN.md and RUNTIME-REVIEW.md define the reviewed scope. PUBLIC-READ-RUNTIME-READBACK.json has SHA256 8cf8a233b3ab3f0383251fe627d0cb443d0248371313661dcdcef4235e74c4ee. Its data-only checker ran successfully once; it reads Git, logs and artifact bytes, requires the original workspace layout and refuses overwrite. It does not rerun archived helpers or product code.

Reproduction and limits

On the recorded Windows Rust/Cargo1.98.1 gnullvm toolchain, use one compiler job with incremental compilation disabled. Exact commands and environment are in each receipt. Principal commands are cargo test --locked --offline -p oa-core --lib, cargo test --locked --offline -p oa-core --test mixed_source8_read, cargo test --locked --offline -p oa-core --doc and cargo clippy --locked --offline -p oa-core --all-targets -- -D warnings. The integration receipts preserve exact selected targets and filters.

Eleven named core stack controls and the existing deep structural-writeback integration case pass. This does not resolve the separately documented full-pipeline small-stack limitation or qualify every depth/platform. Preserve DEPTH_128_VALIDATED=false and logical-accounting exclusions. Mixed CLI discovery, graphical editing, typed save/history integration and application completion remain separate work. Linux/WSL checks remain user-deferred; the published preview is unchanged.
