PYPI CONNECTED
Encoding The Grammar Of Diagrams
Bounded structural diagram codec · ZPE-Diagram · PyPI zpe-diagram v0.1.0 · github.com/Zer0pa/ZPE-Diagram
Most diagram exports flatten a structured drawing into a picture. Six declared synthetic SVGs round-trip through ZPE-Diagram as explicit graph state — geometry, color, stroke width, and draw order all exact.
Three out-of-scope probes — fills, dashed strokes, palette escapes — are refused at the door instead of silently approximated. This is not compression and not a general SVG renderer. It is a bounded codec that keeps the rules that make a diagram readable as a diagram.
01 · THE GAPLOST IN EXPORT
A diagram exported as an image loses the grammar that made it a diagram.
02 · MARKETSWEDGE MAP
Diagramming and adjacent archival categories · the wedge is line-based technical drawings, not the whole graphic design market.
03 · VALUE
$1.9B2030
Diagramming software by 2030; ZPE-Diagram keeps line-based drawings readable as drawings after export.
04 · INSIGHT
A diagram's grammar is the draw order, not the pixels.
05.1 · CURRENT TECHPIXELS ONLY
Standard diagram exports preserve appearance, not intent. The file shows lines in roughly the right place while losing the structural roles, the connection types, and the order in which a person actually built the drawing.
05.2 · OUR TECHKEEP THE GRAMMAR
ZPE-Diagram keeps the grammar. On six declared synthetic line-based SVGs, geometry, a frozen eight-color palette, quantized stroke width, and draw order all round-trip exactly. Three out-of-scope probes — fills, dashed strokes, palette escapes — are rejected at encode time rather than silently coerced into something they are not.

08.1 · WHAT DETERMINISTIC MEANSFIXTURES + REJECTS
Grammar here means something precise: the rules that make a drawing readable as a diagram rather than a pile of lines. Geometry encodes where elements sit. Style encodes how connections differ. Draw order encodes the sequence in which a person placed them. ZPE-Diagram keeps all three axes on committed fixtures and replays them byte-for-byte. On the bounded surface of six declared synthetic SVGs, structural, style, and draw-order fidelity each measure 1.000 — and the three out-of-scope probes never enter the packet.
08.2 · THE FIDELITY GAP
Honest Blocker ·
No fill encode path. No dash encode path. No arbitrary SVG coverage. No compression claim. The current evidence is six synthetic fixtures plus three out-of-scope rejects. Real-world corpus closure, the is_diagram_header() boundary profile, and stroke-width normalization beyond the synthetic packet all remain open work.

DIAGRAMS with a receipt.
09.1 · THE AMBITION
The ambition is to make exported diagrams behave like the structured objects their authors meant them to be: archivable, comparable, searchable by structure rather than by pixel. A docs team, a standards committee, or an engineering archive should be able to trust that the drawing they store is the drawing they later retrieve.
09.2 · WHAT WORKS NOW
Working today, on six declared synthetic SVGs: geometry, style, and draw order survive encoding exactly.
09.3 · WHAT'S STILL OPEN
Still open: public corpora, header-boundary profile, and stroke-width handling outside the synthetic packet.
09.4 · DOCS · NEAR-TERM (12–24 MO)
Docs teams keep diagram meaning
A documentation team that exports a system diagram no longer ships a flat picture. The export carries node positions, line roles, and draw order, so the next writer can update the diagram instead of redrawing it from scratch.
09.5 · PIPELINES · NEAR-TERM (12–24 MO)
Pipelines refuse the wrong input
An archival pipeline that ingests diagrams now receives either a clean bounded object or a clear refusal. The operations team stops debugging silent visual corruption later and starts seeing rejection reasons at the moment of ingest.
09.6 · STANDARDS · MID-TERM (24–48 MO)
Standards bodies archive structure, not screenshots
ISO, IEEE, and ANSI technical drawing submissions can travel as structural objects with geometry, color, and draw order intact. A standards committee can compare two revisions of a wiring diagram or process flow without arguing about which export tool rendered it.
09.7 · DIFFS · MID-TERM (24–48 MO)
Diagram review moves off pixel overlays
Two versions of an architecture diagram become a structural diff: which boxes moved, which lines changed role, which elements were reordered. Reviewers stop squinting at overlaid screenshots and start reading change lists they can talk about in meetings.
09.8 · PROVENANCE · PARADIGM (48 MO+)
Drawings acquire chain-of-custody
A technical drawing in a regulatory submission, an engineering archive, or a patent filing can be proven identical or different across decades. Drawings stop being images and become governed structural objects that survive the people, vendors, and tools that produced them.
