The Mind of Tashi — leaderboard runs
The durable, public, append-only run log behind the leaderboard in the
playable Space.
One JSON file per completed run under runs/, so concurrent climbers can
never race-clobber each other's submissions.
To enable the board on the Space, set the Variable
LEADERBOARD_REPO=build-small-hackathon/mind-of-tashi-runs and the Secret
HF_TOKEN (write scope). Without them the UI shows "Leaderboard offline".
Layout
runs/
<unix_ts>-<run_id>.json one completed run
Run schema
| Field | Type | Notes |
|---|---|---|
run_id |
str | 12-hex uuid |
ts |
int | unix seconds |
username |
str | ≤40 chars |
source |
str | hf-oauth (verified) or guest (typed name) |
total_turns |
int | turns across the whole run |
total_seconds |
float | wall-clock |
per_level |
list | {opponent_id, turns, seconds, won} per rung |
won |
bool | full ladder cleared |
backend |
str | llama.cpp / mock — which opponent mind played |
Identity policy (server-side)
On the deployed Space the OAuth username from the session overwrites
whatever the client posts (source="hf-oauth"), so you cannot submit as
someone else. Run locally (SPACE_ID unset), the typed name is trusted and
tagged source="guest". The leaderboard UI shows a ✓ hf badge on verified
rows.
Ranking
top_runs counts only won runs, keeps each user's single best clear
(fewest total_turns, ties broken by lowest total_seconds), and returns up
to 20. Every attempt (including losses) is stored for analytics density; only
wins rank.
