// DisaggProfileHandler is a ProfileHandler that orchestrates prefill/decode disaggregated serving.
//
// # Disaggregated mode detection
//
// In Dynamo's native architecture, disaggregated mode is determined by whether prefill workers
// actually exist at runtime (the is_disaggregated flag in the Rust KV router). However, the
// GAIE EPP framework determines profile availability at configuration time, not at runtime.
// To bridge this gap, DisaggProfileHandler uses the EPP profile mechanism as a proxy:
// it checks whether a "prefill" scheduling profile is registered in the config. If prefill
// workers are configured but none are actually running, the prefill profile's label-filter
// will find zero pods, causing the profile to fail — and the handler gracefully degrades
// to aggregated mode (see below).
//
// # Scheduling flow
//
// On each scheduling cycle it:
// 1. Checks whether a "prefill" profile is registered in the config.
// 2. Writes PrefillEnabledState into CycleState so scorer plugins can read it.
// 3. If a prefill profile exists: runs the "prefill" profile first, then the "decode" profile.
// The "decode" profile is the primary (the pod the request is ultimately sent to).
// 4. If no prefill profile exists: runs only the "decode" profile (pure aggregated mode).
//
// # Graceful degradation
//
// When a prefill profile is configured but no prefill workers are available at runtime,
// the handler degrades gracefully to aggregated mode on a per-request basis:
//
// 1. Pick (iteration 1): prefill profile exists → writes PrefillEnabled=true → runs prefill profile.
// 2. Prefill profile runs: label-filter finds 0 prefill pods → profile fails → result is nil.
// 3. Pick (iteration 2): sees prefill result is nil → overwrites PrefillEnabled=false → runs decode profile.
// 4. Decode scorer runs: reads PrefillEnabled=false → passes isDisaggregated=false to the Rust
// decode router → full KV cache overlap scoring is used (overlap_score_weight=1.0).
//
// This means the same YAML config works transparently for both aggregated and disaggregated
// deployments. If prefill workers come up later, subsequent requests automatically use
// disaggregated routing. If they go down, requests fall back to aggregated mode.

### Header Routing Hints
Since v1.2.1, the EPP uses a **header-only approach** for communicating routing decisions.
The plugins set HTTP headers that are forwarded to the backend workers.
Since v1.5.0-rc.1, the EPP uses **headers and body mutations** for communicating routing decisions.
The plugins set HTTP headers for worker targeting and inject pre-computed token IDs
into the request body (`nvext.token_data`) so the frontend sidecar can skip redundant tokenization.
