Checkpoint continuation could fail after dependency installation or as accumulated model/tool history grew. This release allocates command slots durably, restores fully completed canonical command receipts, compresses checkpoint history losslessly within an explicit 8 MiB raw bound, and streams canonical Git source identity independently of runner transport archives. Tracked source remains included even when ignored; generated ignored dependencies retain their separate transport rules.

Source listing and text search now return explicit continuation pages, while complete manifests hash every eligible file. Stable tracked deletions and deletion-only command changes retain their provenance. The release also stages full branding assets with a compact context, retains nine granted static tools and frozen design descriptors, preserves verified GitHub delivery links, and binds maintenance lifecycle/questions/owner answers to an exact native creation receipt. Backend 0.2.43 keeps the unchanged Studio 0.2.42 assets and captures.

Validation:

• Fresh V12 native250 (251 requests), SQL54, allocator/restore/codec SQL24, and source/paging SQL6 passed with retained cleanup and zero real model calls. Five explicit test-fixture adaptations preserve every production byte, all 22 loader inputs, the 35-module admission closure and the 315-template catalog. The eighth profile preserves all seven historical profile literals.
• Configured Ruff, formatting of 868 files, mypy over 306 source files, and 45 current profile/reader host tests passed. Standard wheel/sdist payload verification covered all 2,415 frozen inputs; the extracted 685-member package passed read-only version, current-profile, resource and import-isolation checks.
• All 141 cases across the eleven modules affected by the previous full-CI failure passed together against isolated PostgreSQL. Revocation hooks use the current awaited boundaries, model-prompt capture includes user content, and controlled profile fixtures use the current host. Historical seals and production guards remain unchanged.
• Full CI runs on this updated head. Live generated-product acceptance remains a separate tracked result.
