Vigilens is a PPE and site-safety review assistant that helps a human reviewer check a site image for personal protective equipment (hard hat, high-visibility vest) and restricted-zone entry. The operator uploads an image and draws zones for that camera. One SAM 3.1 call through the Meta Model API segments people from the image; each person crop then goes to Muse Spark 1.3 for a strict, schema-limited helmet/vest observation. Every model observation is recorded as unvalidated and always needs a human decision - Vigilens does not clear anyone as safe and makes no compliance decision. The operator confirms or rejects each observation, enters their own rules (nothing is prefilled), and receives a private review report combining the model's observations with their own confirmations. Severity and rule evaluation are deterministic and operator-configured, not model judgement. The private report uses offline face detection to propose regions for human-reviewed, report-only masking; the live review stays unmasked, and download/export are gated off by default. The idea behind it: try prompt-based PPE review through the Meta Model API instead of training a custom detector per site. Status: a prototype built during the hackathon window (commits Oct 27 - Nov 4, 2026). Local synthetic tests pass and separate hosted checks with generated imagery and a public-domain photo completed real SAM 3.1 and Muse Spark 1.3 calls; the latest post-deploy hosted checks are partially blocked (a stored-result reopen returned HTTP 429, cause unresolved), so current hosted behavior is not fully verified and real-footage accuracy is not established.
