Engine Feature Crosswalk

This page is a reviewed website derivative of the local SelfDoc report:

D:\code\ccode\labtalk\reports\selfdoc\x64base_engine_feature_crosswalk_v1.md

The report was generated from local source evidence plus harvested HELP/manualgen tables. It found 28 feature lanes, 290 harvested HELP commands, and source evidence across the configured scanner globs.

Status language:

runtime-evidenced means the scanner found supported/implemented HELP command evidence and source evidence.
source-evidenced means source evidence exists but the website summary should still be reviewed against HELP.
help-catalog-evidenced means HELP/catalog evidence exists but source mapping needs review.
planned or in progress means the lane is real work, but should not be marketed as complete.

Manualgen result

The same pass ran the guarded manualgen commands. Current state:

Inventory: 25 sections, 18 media files, 12 appendices, 4 manifests.
Dry-run manual artifact generated under docs/manuals/developer/manualgen/generated/manualgen_build_dry_runs/.
Validation status: FAIL because manualgen requires Python >= 3.12 and this run used Python 3.11.0.
Boundary failures: 0.
Parity review: not publication-equivalent; all 25 sections need review before replacing any publication.

This is still useful: it proves the manual generation path is alive, but it must be run with Python 3.12 and reviewed before a publication replacement.
