07 — Community Par Corrections
How the community par correction system works, what gets stored in Supabase, how the verified badge is applied, and why five corrections unlocks something significant.
7,008 courses. Sourced from a public dataset. Not every par value in that dataset is correct. Disc golf courses update layouts. Signs lie. Hole 4 is a par 4 — the sign says par 3 and the sign has always said par 3 and the sign is wrong and everyone who plays this course knows the sign is wrong.
Rather than let bad par data calcify forever, Ghost Card has a community correction system. If you play a hole and the par seems off, you can submit a correction after the round. The correction is written to Supabase, tracked, and reflected in how the course displays in CoursePicker for other users.
Corrections are submitted post-round — you can't flag a par mid-hole. After a round ends (at Round Complete or after saving), you'll see an option to flag par issues if any holes seemed incorrect.
Sign-in required
Par corrections require a signed-in account. The system tracks corrections by user — your correction count is what triggers the Bone Collector tag at 5 submissions.
To submit a correction:
Corrections are stored in Supabase on the course record. Each submission updates two fields: last_corrected_by (your account) and correction_count (total submissions for that hole).
Corrections from multiple users on the same hole accumulate. The par data updates toward the most commonly submitted value. This is a community system — if enough players flag the same hole with the same correction, the data improves for everyone.
There's no moderation queue. No approval step. Submissions go directly to the course record. This works because the community has no incentive to corrupt par data — wrong pars hurt everyone's scoring accuracy equally.
Courses that have received at least one community correction show a Verified badge in CoursePicker. Courses with no corrections show Unverified. This isn't a quality rating — it's a data transparency signal. Verified means humans have looked at it. Unverified means you're trusting the original dataset.
The badge appears next to course names in search results and on the course detail view before you start a round.
Submit 5 par corrections — across any courses, in any order, over any number of rounds — and the Bone Collector bag tag unlocks automatically.
Your correction count is visible in the Bag Tags tab — tap the Bone Collector tag (locked) to see your current progress. The count never resets. Every correction is permanent.
The Bone Collector is one of three Legendary-tier bag tags. It's the only Legendary tag tied to community activity rather than in-round performance. It's earned slowly. That's the point.
