## Why

The existing fixed-profile harness treats each 1,179-byte datagram as an encoded frame, so its reported frame rate, frame boundaries, bitrate, queue pressure, and processing evidence do not model the named 60/120 FPS profiles.

## What Changes

- Generate deterministic variable-size encoded frame units at the named frame rates and target bitrates, including bounded keyframes.
- Traverse native Apollo recovery, production queues, the production pacer, QUIC framing, and independent reassembly.
- Assert frame count/rate, bitrate, exact bytes and boundaries, clean loss attribution, latency, and resource bounds.
- Keep short smoke tests separate and leave all prior normative artifacts unchanged.

## Capabilities

### New Capabilities

None.

### Modified Capabilities

- `gateway-qualification`: Fixed-profile evidence measures complete encoded frame units rather than one datagram per frame.

## Impact

The existing qualification harness and canonical qualification specification only. No codec operation, production dependency, or normative run before immutable consumer publication. Requirements: P3C-002, P3C-008, P3C-029, P3C-030, P3C-033, VER-009, VER-010, OPS-015.
