dim_observation_window

Deduplicated coverage and reliability profiles. Each unique combination of coverage metrics gets a surrogate key (observation_window_id) referenced by fact_energy_15m.

Column	Type	Description
`observation_window_id`	INTEGER	PK. Surrogate key
`minutes`	DOUBLE	Minutes of observed data in window (<= 15.0)
`seconds_observed`	DOUBLE	Total seconds with telemetry coverage (capped at 900)
`data_coverage_pct`	DOUBLE	Observed coverage as percentage: 100 x `seconds_observed` / 900
`seconds_reliable`	DOUBLE	Seconds from Silver rows passing all reliability checks (capped at 900)
`reliable_coverage_pct`	DOUBLE	Reliable coverage as percentage: 100 x `seconds_reliable` / 900
`is_reliable_window`	INTEGER	Binary flag: `1` if `seconds_reliable` >= 720 (80% of 900 s), else `0`

Row count: 1,554 (deduplicated from 4,103,703 source rows)
