Two production-grade hardening additions and one cost optimisation. FLUXAI AUTONOMY RESTORED (api/chat) - Brings back the multi-step agentic flow that the system prompt was always designed for. The "temporarily removed maxSteps" comment is gone — replaced with the AI SDK 6 equivalent stopWhen: stepCountIs(5). - Cap at 5 chained tool calls per turn bounds latency + LLM cost. - maxDuration raised 30s → 60s to absorb tool-chain runs. - Result: one user prompt now triggers, e.g. search_installations → energy_savings_calculator → show_case_study → schedule_consultation in a single turn — exactly the SPIN methodology in the prompt. RATE LIMITING (src/lib/rateLimit.ts + api/chat) - Token-bucket per IP: 30 messages burst, sustained 30/minute. Trips to 429 with Retry-After + X-RateLimit-Remaining headers when abused. - IP extracted from x-forwarded-for (Nginx already passes this). - In-memory Map with 10-min GC of stale buckets — no Redis dep. If we scale to multiple replicas later, swap the Map for Upstash. - Protects the OpenAI quota from someone hammering the chat endpoint. IMAGE PIPELINE (src/lib/imageOptimizer.ts) - sharp-based optimizer: auto-orient (EXIF), cap at 2560px long side, re-encode WebP@85, content-hash filename. Re-uploads with same content reuse the same hash; new content gets a new URL — perfect cache invalidation without header tricks. - Opt-in via optimize=1 form/query param on /api/assets POST. - Hero CMS and Site Settings uploads turn it on automatically (those are user-facing brand assets where compression matters most). - App/news/parts uploads remain untouched (editors may be uploading CAD drawings, datasheets, etc. that shouldn't be transcoded). - Falls back gracefully to a no-op for unsupported formats (SVG, GIF, videos, anything sharp can't decode) so it never breaks an upload. DOCKERFILE - Adds vips/vips-dev for sharp on Alpine + --include=optional so the @img/sharp-linuxmusl-x64 prebuilt is downloaded - Explicitly copies node_modules/sharp + node_modules/@img to the runner stage (Next.js trace can miss conditional deps). NO DB SCHEMA CHANGES.
