This release makes PDF takeoff reliable and hardens the whole platform against out-of-memory crashes. Opening a PDF from Project Files no longer floods the console with 404s, because takeoff opens against a real takeoff document instead of a file id it could not resolve. Uploading a large or drawing-heavy file can no longer take the container down: every document, revision, PDF-split and photo upload now streams to disk under a size cap instead of reading the whole body into memory, and PDF parsing runs in an isolated, memory-capped subprocess with a page cap, so a heavy file degrades gracefully instead of triggering a silent out-of-memory kill. The same care already runs across element matching, reporting, BIM, the point cloud and file search, with a global request-size limit above all of it. The Alembic warning that filled container logs is resolved, it was only the health check resolving the migrations path from the wrong directory and never a sign of a real problem.

The desktop app parses takeoff PDFs again. The packaged build runs as a single frozen binary that could not launch the isolated parser, so uploads there had started coming back with no pages; it now parses in-process with the same safeguards. The published container is secure by default: it runs a production posture out of the box, so the interactive API docs are hidden and a wildcard CORS origin is stripped, and it still starts with zero configuration by generating a strong signing secret on first boot and keeping it on the data volume so sessions survive a restart. A plain pip install now ships every interface language, where before a clean install quietly dropped six of them.

Scheduling is more capable and more correct. The module gains a dependency editor and an editable activity grid, and rescheduling now anchors each chain at its own start date, so a project with several independent chains no longer places later work before the task it depends on. The 3D model viewer loads noticeably faster, serving compressed geometry tiles and moving the parse off the main thread while keeping every element and its properties intact. Bill of Quantities paste tells you which rows it skipped instead of dropping them silently, quick takeoff links exactly the elements you isolated, and a quantity can be driven by a per-element formula.
