Honesty fixes from the old release-line PR, re-applied onto current main (v1.6.0+). Most of the original conflicted with the #102/#104/#116 placement work, so it was ported by hand; the base is now main.

Kept:

• A project with several plates is never called ready or "fits the bed" when each plate fits alone: placement card, preflight bed check, Ready Now and the Doctor READY note say Studio cannot check where the plates sit.
• No app or engine text recommends Arrange all plates as a fix (guard test; the held guide is not scanned).
• Recommended mode says when the creator's supports are not kept; the Validation Center only says values are kept for Preserve.
• Intelligence Report headline, next action and comparison lines name every check that was not verified (bed fit, object spacing) instead of "found no risks".

Left out on purpose: prime-tower detection, guide pages, release metadata, and the deferred regrid/tower experiments (#98/#110). Original head is kept in local ref hold/pr109-original-b1e79d7.

Verified: backend pytest 3737 passed, 49 skipped; desktop tsc clean, vitest 1192 passed; CI green on the head. Static review: Sol APPROVE, Opus APPROVE-WITH-NOTES (optional notes only).

Known follow-ups: treat a bed fit that raised (None) as not verified; pass the prepare mode to the live report endpoint; per-object support overrides are not considered by the supports note.

📝 Walkthrough

The changes report multi-plate placement as unverified, update placement guidance, and distinguish preparation outcomes for creator settings and supports. Backend reports and desktop views reflect these results, with tests covering the updated behavior and wording.

Changes: Placement and Preparation Reporting

Layer / File(s)	Summary
Assess placement and bed fit backend/snapstudio_core/plate_placement.py, backend/snapstudio_core/preflight.py, backend/tests/test_honest_claims.py, backend/tests/test_plate_placement.py, backend/tests/test_preflight.py	Multi-plate assessments report when Studio has not established plate positions. Preflight returns an unknown bed-fit result when it cannot verify those positions. Tests cover multi-plate and single-plate cases.
Report placement status in readiness and UI backend/snapstudio_core/doctor.py, backend/tests/test_honest_claims.py, desktop/src/api.ts, desktop/src/lib/placement.ts, desktop/src/lib/placement.test.ts, desktop/src/lib/readiness.ts, desktop/src/components/PlacementCard.tsx, desktop/src/components/PlacementCard.test.tsx	Doctor and desktop placement results carry multi-plate uncertainty into user-facing actions and verdicts. The desktop placement view reports an unverified, non-fixable result when there are multiple plates and no reported off-plate objects.

Intelligence reports name checks that were not verified. Tests scan application text for Arrange recommendations, and the changelog records the reporting changes.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Do not claim that every object is on the plate when placement is unverified.

For a multi-plate project whose plates fit individually, assess() returns no off_plate items but sets placement_established to false. If a caller requests a placed copy, this branch replies, “every object is already on the plate.” Check placement_established before returning that reason. For unverified placement, return the assessment summary instead.

Make the success message depend on the preparation mode.

If the user prepares with Recommended settings, this line still says “creator settings kept where possible.” The mode-aware PrepareSettingsSummary below explains that Recommended can replace those settings, including enabled supports. Use prep.prepare_mode to give Recommended copies a starter-settings message. Reserve the “kept” claim for Preserve copies.

Carry partial multi-plate placement checks into the report.

For a clean multi-plate result, bed_fit.assess() returns overall_level: "ok" even though positions across plates are not checked. C.doctor_contributions() drops ok findings, so the Intelligence Report has no risk or not_verified entry for this limitation. Its Project Doctor summary can also say that the placement check found nothing off the plate.

Add an explicit partial-placement field and include it in not_verified. Update overall_text so it does not claim that the placement check was complete.

Check the written support declaration in Preserve mode.

If the source has enable_support="1" but does not declare enable_support in different_settings_to_system, Preserve can leave the value undeclared. Snapmaker Orca then uses its supports-off preset, but this return suppresses the warning. Check the written declaration in both modes. If Preserve loses effective supports, give Preserve-specific guidance instead of suggesting Preserve again. The repair path retains source declarations and declares changed keys; it does not necessarily declare an unchanged enable_support value. (raw.githubusercontent.com)

Keep the unknown-mode message neutral.

If a user opens an unprepared 3MF with customized-preset markers, /report calls service.report(path) without a mode. This branch then says Studio’s starter settings replace its values, although Studio has not prepared the file. State that the report cannot determine whether the values will be kept or replaced.
