Changelog

Unreleased

• Added deterministic, token-bounded product-family normalization in the article resolver for Stex/Secutex, Bfix/Bentofix, and Sgrid/Secugrid.
• Added a minimal OpenWebUI Pipe that maps each OpenWebUI user/chat to the existing RollCalc conversation API, renders only deterministic messages, and exposes validated reports through a configurable browser-public URL.
• Added friendly adapter errors, per-chat asynchronous request serialization, server-side Basic Auth without credential-bearing links, deployment/demo documentation, and mocked OpenWebUI Pipe tests without a RollCalc dependency.
• Added a direct, dependency-free Ollama /api/chat client, defaulting to the configurable qwen3.5:35B-A3B model, with temperature 0, thinking disabled, timeout handling, and JSON-schema-constrained output.
• Added strict new_calculation, multi-field modify_calculation, and unsupported NLU validation; calculated and unknown fields are rejected.
• Added process-local conversation state, deterministic German clarification/result templates, and temporary input-only PDF references.
• Added authenticated conversation creation/message/report routes and a python -m rollcalc_chat terminal demo with optional diagnostics.
• Added mocked Ollama, schema, conversational workflow, API, and authoritative conversational PDF tests; normal tests do not require Ollama.
• Added roll_calculation.py as the authoritative headless service for direct diameter ranges, optional roll weight, article/core resolution, and warnings.
• Added JSON-serializable calculation request/state/result models, structured clarification/failure statuses, and controlled mutation/recalculation.
• Reject caller-supplied result fields in both requests and calculation state, and require clarification for duplicate exact article identifiers.
• Added authenticated calculation and modification API boundaries for future tool use; no LLM integration was added.
• Routed the active direct-diameter UI and PDF generation through the deterministic service and rejected caller-supplied engineering result fields.
• Added archive-safe PDF filenames with date and HHMMSS time.
• Added an authenticated Download PDF action for valid direct roll-diameter results.
• Added compact, one-page A4 reports with article data, material inputs, minimum/average/maximum diameter, optional roll weight, active forklift warnings/notes, generation time, and build metadata.
• Embedded repeated diagonal INTERNAL USE ONLY marks directly in the PDF page content stream. This is an internal-use marking and deterrent, not DRM or a tamper-proof control.
• Added strict report-model validation and filesystem-safe archive filenames.
• Added PDF model and endpoint tests without adding a new runtime dependency.
• Renamed the PDF result section to Calculation Results and added the effective roll length as a fourth primary result card.
