What changed

A reason to come back. The last 30 days on tinycorp.ai, dated, off the records the site already keeps: bots that died and what their own trades say, forward-test windows that opened and closed with their verdicts, what the Evolution Lab proposed, and each month of the price tape as it was exported. Every line links to the page that holds the record. Everything is paper trading; this page counts things and never sums a P&L across bots.

Day by day

Where each line comes from

Bot archived

A bot whose status is archived. The database keeps no archive stamp, so the date is the last day the engine ran it (strategy_runs) — the engine stops running a bot the moment it is archived, and every live bot's last run is today. The sentence after the date is the Graveyard's: arithmetic on that bot's own paper trades, no narration.

Window opened / closed

The same records Forward tests renders: a bot activated out-of-sample opens a window with its rule frozen as a version snapshot; the engine's gate (14 days and 30 closed paper trades) closes it and stamps the date. The verdict — ahead, behind, too thin — is the sign of that bot's own paper P&L over 25+ closed trades inside the window.

Evolution Lab

A run appears only if Grok proposed at least one mutation (evolution_runs); a run that proposed nothing is not news. A promotion is a candidate whose status is promoted — it won its head-to-head backtest and became a new version of its bot.

Price tape

Each month's export as the dataset manifest records it: rows, file, checksum, the date the export finished.

What is not here

No money. No summed P&L. No sign-ups, no visitor counts, nothing from the studio's other three sites. If a record has no date, the line is left out and the gap is printed above rather than filled in.

Machine-readable

/changes.rss (RSS 2.0, the last 90 days) and /api/changes.json (?days= up to 365), both carrying the same items and the publisher object every API on this site returns.
