 body:
 
-The first desktop MVP moved Thinkloom from the workspace framework into a Tauri
-2 application. React and TypeScript provided the interaction surface, while the
-Rust service layer took responsibility for local persistence and native
-operations.
+The July 17 build brought together the milestones that turned Thinkloom from a
+writing-workspace framework into a reviewable native product.
 
-This milestone connected the main workflow end to end: project state, idea
-curation, drafting, version history, provider boundaries, exports, backups, and
-an inspectable provenance trail. SQLite held live state while canonical files
-and hidden Git checkpoints provided durable, reviewable recovery points.
+First, Thinkloom became a Tauri 2 desktop application. React and TypeScript
+provided the interaction surface while the Rust service layer took responsibility
+for local persistence and native operations. The main workflow connected project
+state, idea curation, drafting, version history, provider boundaries, exports,
+backups, and an inspectable provenance trail. SQLite held live state while
+canonical files and hidden Git checkpoints provided durable, reviewable recovery
+points.
 
-The goal was not merely to wrap a web interface in a desktop shell. The native
-boundary made local files, operating-system credentials, atomic writes, and
-offline ownership part of the product itself.
+The product boundary was then narrowed deliberately. Hosted and browser-facing
+scaffolding were removed so Tauri became the sole application target. That made
+the local-first promise concrete: manuscripts, project state, and credentials
+belong on the writer's machine.

+Model prompts also moved into documented, user-editable JSON templates. The
+application creates user-owned copies and reloads them before each request, with
+validation that leaves writing unchanged when configuration is invalid. That
+keeps model behavior inspectable rather than hidden in the application.
+
+Finally, the project was prepared for Build Week with its demo, judging guide,
+license, collaboration record, and release-oriented documentation. The
+submission materials separate completed functionality from distribution work
+that still needs external assets or owner decisions.
