Decision: Proceed with safeguards.
- Help a small transit agency find the few GTFS changes most likely to help riders.
- Give support staff a reproducible, plain-language view before an agency call.
- Preserve open evidence for researchers and feed consumers.
| Harm | Who is affected | Control and evidence |
|---|---|---|
| A low grade is treated as staff or service performance | Agency staff and vendors | Fix-first copy, comparison policy, no compliance claim, evidence-backed corrections |
| Small or rural agencies are penalized for lacking realtime | Small agencies | Realtime is optional and “not yet published” is neutral |
| Old or partial data drives a ranking | Agencies and press | Freshness/measurement eligibility, minimum cohort, dated artifacts, suppression metadata |
| A false listing or ownership claim changes public facts | Agencies | Human review and three evidence paths; requests are unverified by default |
| Automated outreach becomes spam | Agency contacts | Opt-in alerts, polling etiquette, cohort worklists rather than bulk unsolicited delivery |
| An accessibility visualization excludes a user | Disabled users | Semantic values/table alternatives, 320px/keyboard/axe gates, public barrier channel |
Pause publication if scoring cannot distinguish unavailable data from poor data, a comparison lacks a defensible cohort, a correction cannot be traced to evidence, or a core route fails the accessibility gate.
