WalkthroughContinuation requests now preserve extracted user text. Complexity routing can classify recovered continuation tasks when no session tier exists, while retaining session reuse and skip behavior for empty text.

- Around line 127-133: Update extractFromChatMessages to ignore textless user
fragments and continue scanning for later usable human text instead of returning
failure immediately. Preserve the existing BuildInputWithDisposition empty-input
behavior when no usable text remains, while ensuring LastUserText can be
populated for complexity_tier classification when usable content exists.

Summary
When a conversation turn is a continuation (e.g. a tool result following a prior user message), the complexity router previously discarded the extracted input and skipped classification entirely if no active session was found. This left new or recovered sessions without a tier assignment. This PR fixes that by preserving the extracted
ComplexityInputfor continuation turns and falling back to classifying the recoveredLastUserTextwhen no session state is available.Changes
BuildInputWithDispositionnow returns the populatedComplexityInput(includingLastUserText) for trailing-continuation turns in both chat and responses request paths, rather than returning an empty struct.InputContinuationdoc comment updated to reflect thatLastUserTextserves as a recoverable task for safe fallback classification.computeComplexityrestructured so that continuation turns first attempt to load session state, and if none is found, fall back to classifying usingLastUserTextrather than unconditionally skipping. IfLastUserTextis also empty, the skip path is taken as before.TestPreRequestHook_SessionContinuationReusesButDoesNotInitializeTieris renamed and updated to assert that a continuation with no existing session now produces a classified tier via semantic mechanism rather than a skipped result.TestBuildInputWithDispositionextended to assert that continuation cases carry the expectedLastUserTextvalue.Type of change
Affected areas
How to test
go test ./plugins/routing/...Verify that a continuation request against a session ID with no stored state results in a complexity tier being assigned via semantic classification using the last user message, rather than the tier being nil with a skipped mechanism.
