# Optional source-scope presentation fixture Open `model/project.arcadia` only if the parent chooses this optional workflow. The original four-file baseline is copied byte-for-byte under `originals/`; existing simple/representative baseline, expected, and work trees were not changed. Four exact alias-role substitutions merge `assess` and `confirm` into `WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW` (32 ASCII W characters). The four UUIDs, declaration names, include filenames, and prose/comment markers are unchanged. One deliberately absent include, `missing-scope-stress-9e8r6t.arcadia`, is inserted in the entry. `manifest.json` records all original/derived byte sizes, hashes, and before/after UTF-8 edit spans. Static expectations: opening enters source repair with a missing-include error and retains the previous accepted graphical model. Query the W alias in either activity declaration or either use in `links.arcadia`. Definition should offer two declarations; References should report two lexical uses with Partial and Collision flags. These are alias collisions with unique IDs. The ordinary loaded scope should show four included files, zero detached/unverified files, and one missing-include scope issue. Initial Problems may show only the missing-include error: the disk loader skips full compilation once loading has produced errors, so this fixture does not promise a simultaneous duplicate-declaration problem. The independent query supplies the collision flag. Prose and comments still contain the original `@assess` markers and are not substituted or counted as W uses. This is an intentionally invalid, presentation-only fixture. No compiler, oracle, GUI, or native evaluator was executed. Layout, query counts, displayed flags, repair feedback, and usability remain pending native observation. It is separate from the primary workflow and has no expected-save or model-equivalence acceptance role.
