Summary by cubic

Fixes the rope-modernize lane's public type contracts so Result, ConfigFileSourceType, and validate_value resolve from the facades without call-site workarounds. It also adds config/workspace.yaml as the conform topology SSOT, adopts the regenerated Makefile/docs/CI fragments, and lets strict pyproject ingestion accept the duplication-gate table.

Core fixes

• yaml_safe_load returns a failed result on yaml.YAMLError instead of raising.
• The FlextResult TYPE_CHECKING stub inherits the Result protocol and adds the factory classmethods and combinators the protocol lacks.
• u.validate_value gains overloads so type[T], ValueAdapter[T], and TypeHintSpecifier targets resolve to p.Result[T].
• m.ConfigFileSourceType is now a PEP 695 alias; the previous class-attribute union collapsed consumer annotations to None.
• FlextConfig drops its ClassVar re-export block and CSafeLoader fallback.
• Enforcement reverts the ai-hub accessor renames to project scope.
• ProjectToolFlextProject declares [tool.flext.project.duplication] as an optional JsonMapping; PyprojectDocument no longer rejects it as extra.

CI, docs, and tests

• Workflow fragments mint a cross-repo credential when secrets exist (otherwise record NOT EXECUTED) and restore the testmon cache, while the Makefile check gates no longer include markdown-format and markdown-code.
• Docs, examples, and tests move to the new facade names, and the dispatcher example now returns r[str]/r[bool].
• Docs refresh TOCs, update Make command references, replace model_construct with real constructors, and translate security.md to English.
• .envrc tolerates missing stat output and uses ${HOME} consistently.

Absorbed: the lane's validated content landed on 0.12.0-dev via lane/core-479 fast-forward (bd5e961) plus integration absorb (a2d145c): all required typing gates zeroed, api core singleton restored, PydanticBaseSettings re-export un-glued, ResultView dispatcher normalization, project-metadata public part bases. Closing in favor of the integration branch.

Deep re-evaluation (fleet audit bead flext-v4fmn): roughly half this lane already landed (deletions of _config.py and enforcement part 06 are identical at tip). Not landed: result.py's TYPE_CHECKING FlextResult[T] protocol-conformance stub — but tip took a DIFFERENT shape for result.py (128 lines apart), superseding the overload change in _utilities/model.py. Remaining new work = re-derive the protocol stub against tip's current result.py; merging this head would conflict and partially regress. Leaving open for the lane owner to re-derive, per the flext-itpd1.3 coordination.
