// v4.3 Sesjon 5 — STUB. Full schema-validation tests land in Sesjon 6 (Wave 7
|

// Step 29). Sesjon 5 seeds this file with the behavioral fixtures for:
|
|
// - Step 25 — HTML-comment indirect prompt-injection mitigation (Sec T4)
|
|
// - Step 26 — path-traversal + symlink/dotfile filter on loaded files
|
|
//

|
|
// validate behavior without spinning up a headless browser. The voyage
|
|
// playground HTML carries the same logic inline; tests/playground/
|
|
// voyage-playground.test.mjs covers the static-grep that the inline
|
|
// implementations exist.
