Stake movements

Stake changing hands or place: transfers between coldkeys, moves between hotkeys, swaps across subnets. One row per indexed leg — Taosis lists exactly what the chain event said rather than guessing at pairings. Each event states its size in τ. The α of a leg is not in that event: it comes from the StakeRemoved (out leg, fee included) or StakeAdded (in leg) the chain writes beside it in the same extrinsic, and reads — when there is none, or for legs indexed before 24 Sep 2026. A move or transfer within one subnet trades nothing; one across subnets passes through both pools. Indexed since Aug 27, 2026 — this is our index, not the chain's full history.
