Recreate Scientific Figure

Coordinate one backend-neutral four-role protocol. Keep the roles logically separate even when one agent performs all four. Let the user choose draw.io, Microsoft PowerPoint, or WPS Presentation; the choice changes the implementation, never the quality contract.

Use $recreate-scientific-figure-in-drawio as the draw.io Drawer adapter and $edit-powerpoint-live as the PowerPoint/WPS Drawer adapter. Use $audit-scientific-figure as the Reviewer and $correct-scientific-figure as the Corrector.

Preserve backend parity

Require both backends to deliver the same semantic capabilities:

• editable text, shapes, symbols, panels, lines, arrows, and attached connectors;
• editable tables and regular charts: native in COM/OOXML PowerPoint, editable shape composites in Office.js PowerPoint or draw.io when their live APIs cannot insert a native chart;
• stable object names/ids, duplication, grouping, z-order, exact alignment, and equal distribution;
• one picture object per irreducible raster field, with all reconstructable overlays rebuilt separately;
• visible object-by-object construction in draw.io, PowerPoint COM, and connected PowerPoint Office.js; explicitly labeled, checkpointed, and verification-aware file refresh in OOXML fallback mode;
• structure audit plus renderer audit after every region and after the whole figure;
• an editable source file and requested exports.

Do not relax a rule because one backend represents the object differently.

Designer handoff

Treat the supplied reference as the design authority. Extract its design; do not redesign it for convenience.

1. Inspect the full-resolution reference and readable local details.
2. Record the reference size, aspect ratio, reading direction, panel bounds, coordinate transform, palette, typography, and z-order.
3. Assign every region a stable id, bounding box, title, construction order, incoming links, and outgoing links.
4. Inventory every visible item as editable text, editable shape, free line, attached connector, editable table/chart, repeated motif, or irreducible raster field.
5. Decompose grids, prediction comparisons, image stacks, mask rows, and multi-image panels into individual raster fields plus editable titles, frames, grids, legends, arrows, axes, and annotations.
6. Record unreadable text and obscured boundaries as explicit ambiguities. Never invent content.

Produce a reconstruction_spec before drawing. It must contain region ids, object ids, geometry, styles, connector routes, grouping, raster decomposition decisions, and local acceptance conditions.

Drawer handoff

1. Detect the selected backend's current capabilities before choosing objects. For live Mac PowerPoint, require a connected officejs-context-sync task pane and lock it with powerpoint_set_backend before drawing; otherwise report the OOXML fallback instead of promising a live animation.
2. Connect or create an isolated editable document and inspect its structure. For WPS, require explicit target-application fields and never treat a managed file, helper process, or dispatched open request as proof that the deck is open.
3. Establish canvas/slide size, panel skeleton, alignment anchors, spacing tokens, and connector lanes.
4. Draw exactly one logical region from back to front with stable semantic names and nonzero pacing.
5. Return a draw_log containing created/updated object ids, object classes, grouping, and every raster declaration.

Never insert a whole panel merely because cropping is faster or visually convenient.

Reviewer handoff

After each region, require both evidence channels:

• structure evidence from powerpoint_audit_figure or drawio_live_audit_figure plus inspection;
• renderer evidence from a PowerPoint slide export or draw.io screenshot, compared with the matching reference crop.

The Reviewer must report every defect with:

• region and object names/ids;
• category and severity;
• concrete evidence;
• required correction;
• measurable acceptance condition.

Review semantics, text, editability, raster atomicity, geometry, spacing, typography, clipping, z-order, arrow direction, endpoint clearance, path-through-object, connector crossings, and reference correspondence.

Corrector handoff

Give Reviewer findings to $correct-scientific-figure. Require an ordered object-level correction_plan; then return it to the same backend Drawer. Correct the smallest responsible objects. Do not flatten, screenshot, or replace a larger region to hide a defect.

Mandatory local loop

For each region, repeat:

1. Drawer constructs or updates named editable objects.
2. Drawer renders the current whole slide/canvas context.
3. Reviewer inspects structure and render.
4. If any finding remains, Corrector emits exact operations.
5. Drawer executes them and rerenders.
6. Reviewer audits again.

Do not start the next region until the current region has no unresolved finding except a clearly documented source ambiguity.

Whole-figure loop

After all regions pass locally, repeat the same loop for the complete figure. Check cross-region alignment, scale, hierarchy, whitespace, palette, font metrics, routing lanes, global balance, object hierarchy, and reference similarity.

Finish only when:

• readable semantic/text accuracy is 1.00;
• editability coverage of reconstructable content is 1.00;
• clipping and unintended-overlap safety is 1.00;
• layout/alignment confidence is at least 0.95;
• connector clarity confidence is at least 0.95;
• reference correspondence confidence is at least 0.90;
• deterministic audit reports zero hard failures;
• no warning remains unless it is an unavoidable, explicitly reported source ambiguity.

Confidence must be justified by current renderer and structure evidence, not successful tool calls.

Raster gate

Require every retained image to declare:

• raster_reason;
• source_is_tightly_cropped or explicit crop values;
• atomic_raster_unit=true;
• contains_reconstructable_content=false;
• decomposition_note.

Reject any image that still contains separable fields, text, frames, arrows, legends, axes, tables, regular plots, or other reconstructable drawing grammar.

Delivery

Save the editable .drawio or .pptx and requested previews. Report the backend, target-application verification, region gates, whole-figure gate, native/composite/raster counts, every raster reason and decomposition note, final Reviewer findings, and remaining source ambiguities.
