The signals analyzer preprocesses messages by filtering out any message
without extractable text (tool calls, tool results, empty content), but
it stores each surviving entry's ORIGINAL conversation index in the
tuple. `analyze_follow_up` then used that stored index to look up
previous user messages inside `normalized_messages`, which panicked
("index out of bounds: the len is N but the index is M") whenever any
message was filtered out before the current turn — a common pattern for
Anthropic conversations containing <tool_use_error> blocks.
The panic is caught at the tokio task boundary so requests still
complete with the default model, but every affected request logs a
noisy stack trace and silently skips signal analysis, which can degrade
routing decisions.
Fix by walking the normalized list with `iter().enumerate()` and using
the inner position for index lookups. The stored original index is kept
only for display ("Turn N") strings.
Includes a regression test that reproduces the exact panic shape via the
public `analyze` entry point.

* add pluggable session cache with Redis backend
* add Redis session affinity demos (Docker Compose and Kubernetes)
* address PR review feedback on session cache
* document Redis session cache backend for model affinity
* sync rendered config reference with session_cache addition
* add tenant-scoped Redis session cache keys and remove dead log_affinity_hit
- Add tenant_header to SessionCacheConfig; when set, cache keys are scoped
as plano:affinity:{tenant_id}:{session_id} for multi-tenant isolation
- Thread tenant_id through RouterService, routing_service, and llm handlers
- Use Cow<'_, str> in session_key to avoid allocation when no tenant is set
- Remove unused log_affinity_hit (logging was already inlined at call sites)
* remove session_affinity_redis and session_affinity_redis_k8s demos
