Changelog (`1.4.0 -> 1.5.0`)

Release date: 2026-04-19

Major Highlights

DeepVault Nexus 1.5.0 consolidates the shared-app direction into one release story: worker runtime migration, hosted auth, operator gating, and deployment packaging now move together.
The app shell is now organized around clearer ownership boundaries, with runtime, sync, and settings surfaces split more deliberately.
The corpus, Bishop, explorer, and AI View flows were hardened so the app feels more coherent across local, hosted, and release-note surfaces.
Release operations were cleaned up in parallel: changelog structure, parser support, and published release bodies now follow the same cdx-manager-style format.

Python FastAPI worker foundation, CLI parity, corpus endpoint, Bishop proxy, and worker-managed jobs now define the shared backend path.
File-backed runtime artifacts, stable job status values, and SSE progress streaming keep long-running operations observable and restart-safe.
The browser now stays thin while the worker owns corpus loading, scoring, Bishop dispatch, and job execution.

Entra SSO, bearer-token validation, operator allowlisting, and structured access logging make the shared deployment operable for authenticated users.
Hosted-mode UI hides local-only controls and exposes the identity and shared-session affordances needed for multi-user operation.
Docker Compose, Caddy, and the operator runbook provide the deployable package for the hosted stack.

Runtime controls, sync operations, and settings now live in clearer places instead of competing in the same surface.
Persisted theme, navigation, and shell ownership changes reduce friction in the day-to-day operator flow.
Dedicated sync and recovery entry points make the operations path easier to scan and use.

Bishop response flow, generated artifacts, corpus enrichment, and retrieval behavior were tightened so the AI surface reads more predictably.
Explorer card hierarchy, source-link polish, file-type pills, and compact path display improve the browsing surface.
PWA install/update/offline behavior remains part of the product baseline, including install and update affordances.

Changelog sections after Major Highlights now collapse again in the app, keeping long release notes usable.
The changelog parser and release-note tests were updated for the new markdown structure.
VERSION was removed, and package.json is now the single source of truth for versioning.

This release groups the full hosted-app transition rather than a narrow cleanup slice.
GitHub release bodies should be regenerated from this changelog after tagging v1.5.0.
