    1.7.3 (18 October 2026):
    - MultiPolygon standardization: Master and staging tables migrated
to geometry(MultiPolygon, 4326) preventing geometry type mismatch on
digitizing, delete, split, and merge.
    - PlantaLogger import fix: Resolved missing logger import in
Shapefile column mapping module.
    - Split spatial lineage: Injected targetSpatialId and split_child
role for split polygon operations.
    - Merge adjacency tolerance: Added 5 cm distance tolerance for
sub-pixel boundary gap handling.
    - Topology overlap validation: Enabled AllowIntersections on map
canvas so Tier 2 GeoQC detects true overlaps.
    - Block Code column: Added Block Code column to Submission Status
panel with live search filtering.
    - Cross-platform raster opening: Migrated directory explorer to Qt
QDesktopServices.
    - Singleton basemap enforcement: Replaces previous basemap on
selection to prevent duplicate TOC layers.
    - Block name immutability: Locked block name field to read-only
adhering to ERP SSOT conventions.
    - Attribute form selection guard: Added visual warning when
editing attributes without active polygon selection.
    - Offline queue auto-flush: Automated sync on offline-to-online
network transitions with completion signal.
    - Cache retention guard: Prevents canvas layer clearing during
transient empty API responses.
    - Auto-zoom framing margin: Scaled bounding box framing margin to
1.35x.

    1.7.2 (16 Oktober 2026):
    - Standarisasi Penamaan Layer Blok Gros: Menyelaraskan nama layer
blok perkebunan menjadi 'Blok Gros' pada seluruh modul antrean (Panel
Status Antrian Saya dan Panel Persetujuan Admin) agar konsisten 100%%
dengan metadata database (config.role_layer_permissions) dan pilihan
layer dropdown utama plugin.

    1.7.1 (14 Oktober 2026):
    - Tombol & Sinkronisasi Layer Antrean QA/QC untuk Reviewer/Admin
(RBAC & ABAC): Mengaktifkan tombol loadPendingButton pada Tab 1 (Peta
Kerja) dan menambahkan tombol loadPendingAdminButton pada Tab 2
(QA/QC) untuk role Admin dan GIS QA/QC; query endpoint staging queue
/api/v2/staging dengan proteksi RLS PostgreSQL
(config.allowed_estates) sesuai hak wilayah ABAC pengguna; pembentukan
memory layer dengan skema atribut komprehensif; styling gold
semi-transparan dengan garis putus-putus oranye; fitur auto-zoom
kanvas peta ke seluruh cakupan poligon antrean; sinkronisasi dua arah
antara kanvas peta dengan tabel AdminApprovalPanel.

    1.7.0 (13 Oktober 2026):
    - Form Atribut Hierarkis, Autofill Cerdas & Perbaikan Deteksi
Buffer: Dropdown hierarki wilayah dinamis (Regional -> PT -> Estate ->
Divisi -> Blok) dengan Regional & PT read-only otomatis (ABAC),
SearchableComboBox instant-click popup & filter pencarian teks,
multi-layer adaptive layout (Master Blok 5-tab vs
Infrastruktur/Tanah/Sensus 3-tab), eliminasi kolom sistem/audit dari
form teknis, autofill luas geometri planar ke luas_ha & luas_tanam_ha,
kalkulasi otomatis realtime SPH, dropdown standar editable agronomi.

    1.6.0:

config system, Offline Queue auto-retry mechanism, NetworkMonitor
online transition detection, LayerLoader dead code cleanup.

stream loader, Offline GeoPackage layer caching, GeoServer AuthKey
short-lived token integration.

    1.4.0:
    - GeoQC topology & geometry validation engine integration, Staging
Queue Interceptor v2, Drone PMTiles sync, Multi-CRS reprojection.

    1.3.0:
