The growth grammar

Thirteen signals, one tree. Every element below is computed from public data and nothing else - no randomness, no stored state, nothing purchasable.

A 7-year tree, 8373 commits, 10 ripening persimmons, 7 lanterns for code reviews.A bonsai grown from the public GitHub history of maintainer, drawn for 2026-07-15. Season: summer. Maturity level 7 of 13, in a antique pot. Every element is recomputable from public history; nothing here is random or purchasable.kodama · @maintainersummer · 2026-07-158 373commits1 day streak3 this weekfoliage: commits over timefruit: merged pull requestslanterns: code reviewsshoots: commits this weekgreen fruit: open pull requestsbird: issues closedfireflies: stars receivedwind chime: discussions

The maintainer fixture, drawn for 2026-07-15. Focus or hover a row to find its element on the tree.

Rows marked with a dot appear on this specimen; the rest need a history that earns them.
Signal Visual Rule
Account age ● Trunk girth and bends; pot tier plastic → clay → glazed → antique → stone, upgrading at 1, 3, 6 and 10 years
Total commits ● Foliage pads: count and density log2 per active week, so the tree only ever grows and a prolific year cannot flatten a quiet one
Last 7 days ● Bright new shoots the 'I was here this week' signal, and the only one that can shrink
Merged pull requests ● Persimmons, sized by additions the last ten, ripening green → orange over sixty days from the merge date
Open pull requests ● Unripe green fruit converts to a persimmon on merge
Code reviews ● Paper lanterns on the branches log2(1 + reviews) - a lantern is an order of magnitude, not a tally
Issues closed ● A bird, perched or nesting perches at fifty, nests at two hundred and fifty
Stars received ● Fireflies at dusk 3 × log10(1 + stars), so whales do not white out the canvas
Discussions answered ● A wind chime hangs at twenty-five - sound culture, without sound
Current streak Blossom clusters opens at fourteen days, one more cluster every thirty; a break drops petals and leaves the tree unharmed
Longest streak A ring of petals pressed into the soil permanent, at a hundred days - a memory of your best run
The calendar Season: blossom, deep green, red-gold, bare and snowed a function of the date alone, never of the account - everyone's tree turns together
Top languages Optional leaf tint opt in with ?tint=lang

Why this is checkable

Rendering is a pure function of (history, date, options): the same inputs produce byte-identical output forever, so nothing about your tree is a roll of the dice. Every element also carries its own provenance - open the receipts for any account and each ornament will name the public figure it came from and the rule applied to it.
