FilRunway

FilRunway is an autonomous agent that manages its own storage budget on Filecoin.

Every tick it reads its own financial position from Filecoin Pay ; funds, lockup rate, debt, and runwayInEpochs, the number of epochs before it can no longer pay — plus the PDP proving record of each storage provider it pays. Then it decides: top up, hold, decline because it cannot afford the deposit, decline because it hit its own 24h safety cap, or cut a data set whose provider has stopped proving and is charging for work it is not doing.

The decision engine is a pure function with 471 tests. It cannot be talked out of its judgement, and it makes no network calls.

The distinguishing part is provenance. Every decision is written to an append-only journal before the transaction is signed, so any onchain transaction can be traced back to the exact reading, rule and reasoning that produced it:

npm run decisions -- --id

Live on Filecoin Calibration at https://filrunway.vercel.app. The operator secret is published in the README, so you can create the crisis yourself: withdraw its reserves, watch it decide to top up, foll Filfox, then watch it stop — because its own deposit fixed the problem.
