Closes #3665.

Saving XLSX files now preserves whole-object picture and shape click links (cNvPr/a:hlinkClick), including relationship targets, target modes, tooltips and actions. The reader previously discarded this metadata, so the writer had no link to emit. Optional model fields keep older JSON objects compatible; new drawing relationship ids are assigned on save. Equation, ink and connector shapes use the same preservation path.

Internal worksheet-part links resolve through logical sheet names to the actual written worksheet parts, preserving fragments across relocated drawings, custom worksheet filenames, sheet rename and reorder. Deleting a destination worksheet removes the complete click link, preventing a later sheet with the same name from inheriting it; undo restores the original link. Other internal package-part destinations warn and drop rather than produce dangling relationships. Individual text-run links (a:rPr/a:hlinkClick) and drawing-link activation in GridCraft's UI are separate work.

Maintenance refresh (2026-11-13): merged official main through c0ee120a. The shared OPC reader now supplies each original relationship target through target_raw, retaining fragments and external targets without restoring the old parser. Newly inserted WordArt starts without a hyperlink; the test-only JSON dependency remains. Both documentation histories are retained.

Validation on macOS / Rust 1.99.1, required font pin b076417:

• Formatting, strict workspace/all-target Clippy, all eight focused XLSX hyperlink controls, two engine link controls and five WordArt controls pass. All relationship literals and new drawing initializers compile.
• Unfiltered native continuation: 3,885 passed, one known Arabic-caret failure, four ignored, zero filtered tests across 34 harnesses. Required cargo xtask ci stops at the unchanged Arabic-caret assertion (caret x=10 versus text bounds 0..26.875); no full CI pass is claimed. The existing socket-deadline test passes in both this CI run and continuation.
• Explicit workspace doctests, assets, layers, parity and keytips pass. The matching official Rust 1.99.1 wasm gate passes all 13 configured crates (existing UI dead-code and Noto asset-policy warnings).
• No separately rebuilt unchanged-main runtime, new native Excel comparison, text-run hyperlink preservation or GridCraft link-activation claim.

Summary by CodeRabbit

• New Features
  • Picture and shape click-link metadata—including targets, tooltips, and actions—is preserved when importing and saving XLSX files.
  • Internal worksheet links follow sheet renames and reordering, and metadata persists across repeated saves and JSON serialization.
• Bug Fixes
  • Links to a deleted worksheet are removed and are not restored if a sheet with the same name is recreated.
• Limitations
  • Text-run hyperlinks are not included. Preserving link metadata does not activate links in the app; unsupported internal package destinations are skipped.

Walkthrough

Images and shapes gain optional drawing hyperlink metadata. XLSX import and export preserve supported click links and relationship details. Sheet rename and delete operations update internal drawing destinations. Tests and documentation describe the behavior and its limits.

Changes: Drawing hyperlink preservation

Layer / File(s)	Summary
Hyperlink metadata and object defaults crates/model/src/features.rs, crates/engine/src/cmd/..., crates/model/src/..., crates/engine/src/io/tests.rs	Image and Shape gain optional hyperlink metadata. Newly inserted drawing objects and updated fixtures initialize the field to None.
XLSX hyperlink import and export crates/xlsx/src/package.rs, crates/xlsx/src/xlsb.rs, crates/xlsx/src/read.rs, crates/xlsx/src/drawing.rs, crates/xlsx/src/drawing/ink.rs, crates/xlsx/src/sheet_write.rs, crates/xlsx/src/tests/*	Relationship parsing retains original targets. Drawing import reads supported click metadata. Drawing export writes click metadata and optional hyperlink relationships for images, shapes, equations, and ink. Tests cover serialization, round trips, and relationship edge cases.
Sheet rename and delete updates crates/engine/src/cmd/sheet/tabs.rs, crates/engine/src/tests.rs, ROADMAP.md, docs/file-format-parity.md, docs/gaps.md	Sheet rename updates matching internal drawing destinations. Sheet deletion clears matching internal drawing links. Tests and documentation cover these behaviors and preservation limits.

Full details: Title check

Explanation

The title "Preserve whole-object picture and shape hyperlinks in XLSX" matches the main change. The PR adds a DrawingHyperlink model field, reads and writes drawing click relationships in XLSX, and keeps picture and shape click links through saves. Remapping and removal on sheet rename or delete are supporting parts of the same change. The title is concise and specific, and it does not describe anything outside the changeset.

Full details: Linked Issues check

Explanation

Issue #3665 requires DrawingML cNvPr/a:hlinkClick metadata and valid drawing hyperlink relationships to survive same-format XLSX open, save, reopen, and second save. The reviewed head covers this path. The model adds an optional, serde-defaulted DrawingHyperlink on Image and Shape (crates/model/src/features.rs). The reader in crates/xlsx/src/drawing.rs imports external links, fragment targets, and internal worksheet destinations. The writer in crates/xlsx/src/sheet_write.rs (drawing_link) emits click relationships, tooltips, and actions for pictures, shapes, ink, and equation shapes. Package.rs and xlsb.rs keep raw_target. The new offline tests in crates/xlsx/src/tests/drawing_hyperlinks.rs use a synthetic package with linked and unlinked objects, repeated saves, JSON compatibility, equation and ink cases, relocated parts, and unsupported-destination warnings. Engine tests in crates/engine/src/tests.rs cover sheet rename, deletion, and undo/redo. The regression coverage named in the issue (external URLs, workbook destinations, tooltips, no-link controls, repeated saves) is present. UI activation is excluded, as the issue requires. Evidence is the whole-PR summary and PR-reported test results. I did not re-run the test suite or read the full diff.

Full details: Out of Scope Changes check

Explanation

The changes support #3665 or its stated validity constraints. Model fields, reader, writer, and relationship handling implement preservation. Sheet rename and delete handling in crates/engine/src/cmd/sheet/tabs.rs keeps internal worksheet destinations valid, which the issue's workbook-destination requirement needs. The insert, print, and test-fixture updates set hyperlink to None to match the new required field. The raw_target addition to the shared Rel struct and the xlsb.rs change support the same relationship path. Documentation and ROADMAP updates describe this preserved behavior. The ignored Cargo.lock is excluded from review. No demonstrated change falls outside #3665 scope. No UI activation or text-run link work appears in the summary.

Minor · Data Integrity & Integration · Quick win

Invalidate drawing links when their destination sheet is deleted.

delete_sheet leaves image and shape internal_sheet values unchanged. If a new sheet uses the deleted name, XLSX export can write the old link to that new sheet. Invalidate matching links and add a delete-and-recreate control. Clearing only internal_sheet would make export use the original raw target.

Refreshed this existing PR onto official main c0ee120a, preserving the previous head as an ancestor. The current shared OPC reader's target_raw maps to the preserved drawing-link target, retaining fragments and external targets. New WordArt objects start with no hyperlink; the existing test-only JSON dependency remains. Both documentation histories are retained.

Formatting, strict workspace/all-target Clippy, eight focused XLSX hyperlink controls, two engine link controls and five WordArt controls pass. Unfiltered native continuation: 3,885 passed, one known Arabic-caret failure, four ignored, zero filters. Required CI stops at that unchanged caret assertion; the socket-auth deadline test passes in both runs. Explicit doctests, assets, layers, parity and keytips pass, as does the matching official Rust 1.99.1 wasm gate for all 13 configured crates. No full CI, separately rebuilt unchanged-main runtime or new native Excel validation claim; text-run links and activating links remain outside this PR.
