Closes the loop: the model can now build and edit AWS architecture diagrams by declaring structure, and never writes an mxCell again. catalog.ts — 983 AWS icon and 19 group stencils as a name→style map, generated from drawio-ai-kit's catalog (itself generated from jgraph's draw.io shape index). Styles are verbatim, so the official category colours, connection points and aspect=fixed come along for free and nothing is hand-assembled. An invented name is rejected with suggestions instead of rendering as a blank square, which is what draw.io does with an unknown resIcon today. operations.ts — what the model actually sends: add_icon / add_container / move / link / set_dir and so on, applied in order against the tree. Guards the things that break a diagram quietly: duplicate ids (draw.io drops one of the two cells), edges left pointing at a removed node, and moving a container inside itself. index.ts — the entry point. current XML → parse → apply ops → check names → layout → render → new XML. The tree is not stored between calls; it is re-derived from the canvas every time, so a user's manual edits are input to the next layout rather than state to reconcile. Token cost, measured with Claude's tokenizer rather than estimated: - build a VPC diagram: 515 tok as operations vs 3180 as XML (6.2x) - add one icon: 27 tok as an operation vs 3823 re-emitting (142x) - read current state: 216 tok as an outline vs 3180 as XML (14.7x) The 142x is the one that matters day to day: "add a Redis" is one operation, not a rewrite of the whole diagram. Routing in the system prompt sends AWS architecture through this path and leaves flowcharts, BPMN, sequence diagrams, mind maps and Azure/GCP on display_diagram — the layout engine's primitives (nested rows, columns, grids) do not model a sequence diagram's lifelines or a mind map's radial spread, and pretending otherwise would make those worse rather than better. Also: added a NOTICE recording the MIT port and the AWS Architecture Icons terms, and a narrow .gitignore exception so the generated catalog is tracked while the root data/ directory (admin settings, contains secrets) stays ignored. 403 unit tests + 3 new e2e. Verified in the real app: a structural tool call renders with real stencils and container markers; a second call adds one node and keeps everything from the first; an invented name is refused and nothing is drawn. The 13 existing diagram e2e tests still pass.
