RQM Apply Verified Phase Correction

Use this endpoint when you need to apply a known, bounded phase rotation to complex I/Q samples and programmatically assert that numeric preservation invariants (magnitude and MSE) hold — enabling deterministic gating of downstream pipeline steps. Prefer this over a raw phase rotation library when you need server-side assertion verification as a quality gate. Do not use when you need hardware-truth phase measurement, causal diagnosis of phase error, unbounded streaming, or diagnosis of why a phase offset exists.

• Angle out of range: angle_radians must be between -25.13 and +25.13; values outside this range are rejected
• Assertion violation: if computed magnitude error or MSE exceeds caller-supplied thresholds, the call fails with assertion details
• Too many samples: each channel supports up to 1024 samples; exceeding this limit causes a validation error
• Too many channels: maximum 2 channels per request
• Invalid channel_id: must match pattern ^[A-Za-z0-9._-]+$ with length 1–64
• Invalid sample_rate_hz: must be a positive number up to 1,000,000,000
• Payment failure: insufficient USDC or x402 payment not accepted
• Schema mismatch: missing required fields like sample_rate_hz, channels, angle_radians, or assertions
