📄 Description

Summary

  • Upgrades chat history truncation log from slog.Debug to slog.Warn in server/prompt.go, adding messages dropped count and active context length
  • Adds slog.Warn in server/routes.go when embedding input is silently truncated to fit context window

No behavior change, no API surface change — only log level and message improvements.

Context

Resolves #14259

This addresses a pattern seen across 400+ open issues around context length confusion. Users currently have no way to know when their conversation history is being silently dropped. Related issues: #4967 #3839 #2208 #14173 #14116 #12407 #6286 #12474

Test plan

  • go test ./server/ passes
  • go vet ./server/ clean
  • Manual verification: send a long conversation that exceeds context length and confirm the warning appears in server logs
