How many distinct wallets (coldkeys) hold any alpha of this subnet.

There is no minimum or dust floor (any non-zero position counts), and unlike the concentration metrics this one does NOT exclude the owner. Nor does it require delegating to somebody else: a wallet staking to its own hotkey counts. The asymmetry with the concentration metrics is deliberate: this answers "how many wallets hold this alpha", while HHI, Nakamoto and Top 10% answer "how is the tradable float distributed". An explorer with a min-stake floor, or one counting per wallet-and-validator pair, will differ. Each day's history point snapshots this same live figure. Days rebuilt from chain history are the exception: they come from the delegate registry, which cannot see wallets staked to non-delegate hotkeys and sits a few percent lower (about 4% measured on-chain), so do not read that small step in old points as a real move.

How many mechanisms (sub-mechanisms) the subnet runs.

Each mechanism has its own metagraph, with its own UIDs, incentives and weights, and its own slice of the emission; when no split is recorded the alpha is divided equally between them. Almost every subnet runs one. It also explains the Miners count, which is per mechanism.

How many independent miners are currently earning something, excluding the owner's own neurons.

"Active" here means incentive strictly above 0, with no validator-permit, vtrust or stake threshold applied, so explorers using a permit or axon heuristic will report different numbers. It counts distinct miners, so one hotkey registered in several mechanisms counts once. An owner neuron is one whose wallet is the subnet's registration wallet OR whose hotkey is the official owner hotkey, not just the former. A Burn below 100% implies at least one of these miners is earning.
