Check-in Streaks

⚠️ Experimental — generated with no human supervision by the daily MCP pipeline to exercise gno tooling. Not audited. See r/moul/x/daily.

Call CheckIn() once per "day" to keep a streak alive. Miss one and the current streak resets to 1 — but your best streak is never lowered, so a broken run costs the run, not the record.

There is no wall clock on-chain, so a "day" is a fixed window of BlocksPerDay (1000) blocks: day = ChainHeight() / BlocksPerDay. Every streak decision is therefore a pure function of block height — deterministic, replayable, and impossible to game by waiting for a favourable timestamp.

CheckIn()                        → extends or restarts your streak, returns it
Current(addr)                    → live streak (0 once the window has lapsed)
Best(addr)                       → record streak, never lowered
Day()                            → current day index

/r/moul/x/daily/streak/v0        → leaderboard, ranked by best streak
/r/moul/x/daily/streak/v0:g1...  → one address's standing

Current deliberately reports the live truth rather than the stored value: once a window lapses it returns 0 even though the record still holds the old number until the next check-in rewrites it.

Checking in twice in the same window is rejected — the streak only moves when the window does. Only an EOA can check in (IsUserCall), so another realm can't farm streaks on your behalf.
