Issue: https://github.com/aviorstudio/fieldsofrevik/issues/151 — behavior layer stacked on #10. No review requested.

• Source: aviorstudio/gd-responsive, issue-151-responsive-validation, exact head c6e3da096caf5af21767e72f635cb598d473e5f9; baseline/known-good valid resource from 73752cef4ca83ddd9691cf0f80e54a3e469a5b5d.
• Live editor validation — PASS: Godot 4.7.2 editor process reached 21 assertions. Valid control had zero warnings; invalid min_content_width > max_content_width, min_scale > max_scale, and mobile_breakpoint >= tablet_breakpoint produced three field-specific warnings. All six artist edits emitted changed and retained their exact values.
• Save/reopen/recovery — PASS: invalid .tres saved and reopened with all values/warnings intact; layout warning propagation remained finite/stable; correcting only the conflicting minima/mobile breakpoint cleared resource and node warnings; recovered resource saved and reopened valid.
• Installed editor lifecycle — PASS: the exact 28-file package rendered the warning in the Inspector, hid it live after recovery, survived restart, removed its owned UID-form autoload on disable/restart, and preserved the consumer-owned GdResponsive autoload.
• Package/web — PASS: exact-head CI ZIP SHA-256 c3674be9a8b790bb91397b7e3f317ee20c4ccd64b0d2aa2f4d0c68ad1575b3bf; installed-tree SHA-256 a94ef4aa969b33d6f7a8393df7985363af28f5940139ec314a19cc6782db0a82; web export passed. Personal playwright-cli 0.1.18 check at 960×720 loaded the packaged Godot export with zero console errors and visibly rendered GD Responsive Web Smoke PASS | device=0 | width=480.
• Browser evidence:
• Exact-head CI — PASS: https://github.com/aviorstudio/gd-responsive/actions/runs/34739398790
• Commands: strict suite and seven negative controls via ./tests/test.sh; closed package build/verify; clean packaged editor enable/restart/validation/disable/restart; Godot 4.7.2 Web export; playwright-cli -s=gd-responsive open/reload/screenshot against local exact packaged export.
• Tool-dependency finding — PASS / no blanket engine claim: @tool config, layout, inspector plugin, serialization and reopen all execute under the real 4.7.2 editor. The reproduced shutdown diagnostics are narrowly type-allowlisted only for scripted editor exit and are not attributed as a Godot defect.
• Security/performance: no new external input or workload limits; no heavy benchmark; artist values are never silently retuned. Untested until delivery: GitHub Release/GDAM registry bytes and registry reinstall, which block issue closure.

Correction — issue #151 stack replay

The native stack merge rebased this layer from 4b02736cf3bfdb88044760d6cff08fc9ff3ad743 to c6e3da096caf5af21767e72f635cb598d473e5f9. git range-diff showed all three commits as equivalent (=), and refreshed exact-head CI passed: 7 restored controls, 6 scripts, 21 editor assertions, 28-file package, Inspector validation, installed lifecycle, and web export. The head, run URL, package SHA, and screenshot URL above replace the superseded pre-rebase identities; installed-tree SHA remains unchanged.
