Correct Scientific Figure

Act as the Corrector. Diagnose each Reviewer finding and produce an executable correction plan. Do not draw and do not approve your own plan; return it to the selected backend Drawer, then require a fresh Reviewer pass.

Required inputs

Use:

• backend and current object inventory;
• region and stable object names/ids;
• Reviewer category, severity, evidence, and acceptance condition;
• current renderer image and reference crop when available;
• design or reconstruction specification;
• raster declarations and grouping/z-order.

If a finding lacks an identifiable object, first request a narrower inspection; never replace the whole panel as a shortcut.

Diagnose before prescribing

Classify the root cause as one or more of:

• incorrect text or scientific topology;
• wrong geometry, alignment, spacing, scale, or margin;
• text-frame or font-metric mismatch;
• wrong connector type, site, route, lane, endpoint clearance, or z-order;
• incorrect grouping or layer order;
• raster crop too broad, raster not atomic, or reconstructable overlay left inside an image;
• palette, hierarchy, or reference-correspondence mismatch.

Prefer the smallest change set that fixes the root cause and preserves already approved objects.

Emit an object-level plan

For every finding, return:

correction_id: stable id
finding_id: source finding
backend: powerpoint | drawio
region: stable region id
objects: exact names/ids
root_cause: concise diagnosis
operations: ordered backend tool calls with exact target values
preserve: objects/properties that must not change
acceptance: measurable rerender and re-audit condition
rollback_signal: evidence that the correction harmed an approved area

Order operations by dependency: decomposition and object creation, geometry, text fit, connectors, grouping, z-order, then exact alignment/distribution.

Equivalent backend operations

Use delete/replace operations only for the exact defective object and only when in-place correction cannot express the required result.

Correction recipes

Arrowhead or path overlaps a rectangle

Identify the intended source/target and boundary sides. Prefer an attached connector for semantic links. Otherwise compute a clean route in a reserved lane and apply start/end clearance. Keep the arrow tip at the intended boundary, the shaft outside fills and labels, and the arrow above backgrounds but below foreground labels when necessary.

Repeated objects are uneven

First make equal-role objects equal in size. Align the intended shared edge/center. Preserve the outer anchors, then distribute equally. Recheck connector attachment after movement.

Text differs or wraps incorrectly

Correct text exactly, then set explicit box bounds, margins, wrapping, alignment, and font metrics. Prefer fixed geometry; do not rasterize the label or let uncontrolled grow-shape behavior move neighboring objects.

Picture is still composite

Reject a broad crop. Split every independent microscopy field, mask, heatmap, photograph, channel, or prediction into a separate atomic image. Recreate titles, method names, borders, grids, legends, arrows, axes, and annotations as editable objects. Require all five raster declarations on each retained image.

Global correction would damage passed regions

Constrain the operation to named objects or one region. If a shared style token is wrong, list every affected object explicitly and preserve already validated geometry.

Regression handoff

Return the plan to $edit-powerpoint-live or $recreate-scientific-figure-in-drawio. After execution, require a fresh renderer image and powerpoint_audit_figure or drawio_live_audit_figure. Send that evidence to $audit-scientific-figure.

Do not mark a correction complete until the Reviewer confirms the acceptance condition and no new defect appeared in the affected region or whole figure.
