Fetch ONE SUBNET'S emission-pipeline decomposition OVER TIME (#9625) -- emission share, the TAO split (pool-liquidity injection vs chain buys), alpha in/out emission, miner burned fraction, whether emission is enabled -- one point per day, each pinned to the block it was captured at. get_emission_pipeline answers ONE BLOCK for every subnet; this answers one subnet across days, and is what 'was this subnet's miner burn climbing before its emission dropped?' needs. READ THE DEPTH BEFORE DRAWING A TREND: the pipeline columns began on 2026-08-02, so a 90d window returns the few days that EXIST, not 90 -- first_captured_day says where the series starts and oldest_day/newest_day say what was covered. AND READ distinct_observations, NOT point_count, when claiming a value moved: the snapshot writer carries the last capture forward when a fresh one has not landed for a day, so two consecutive points can be THE SAME OBSERVATION. Each point flags that as repeats_previous_observation, and treating a carried-forward day as an independent sample would report a value as FLAT when it was simply not re-measured. window is 7d, 30d (default), 90d or 180d. An empty series is a measurement -- a subnet registered after the capture began returns one legitimately. Mainnet only. Mirrors GET /api/v1/subnets/{netuid}/emission-pipeline/history.
