# Changelog

This project follows semantic versioning. Git tags and GitHub Releases are the source of truth for published versions.

## 0.2.0-alpha.1 - 2026-08-30

### Added

- Agent-native `Requirement → Feature → Work → Verification → Release` lifecycle with strict Gate facts, revision targets, append-only test evidence, release snapshots and maintenance lineage.
- Standalone Agent Tool Surface with cold-start Skill, execution Continuation, Workflow Brief, safe self-claim/completion and conflict recovery.
- Human-centered Project Center with journey, overview, delivery, context, Agent compatibility and actionable workflow states.
- Immutable Project identity, one-Project SQLite ownership, schema/integrity scanning and relocatable Workspace/Repository bindings.
- Optional Host coordination policy, scheduling snapshot and recoverable Local/Git Work Development Bindings for future managed schedulers.

### Changed

- The `v0.2.0-alpha.1` schema is fresh-only. Databases from `v0.1.x` are not migrated and fail closed with reset guidance.
- Work creation starts in backlog; activation, claim and completion are separate CAS-protected commands.
- Project identity no longer derives from a Workspace basename.
- Project Center adds responsive Journey navigation, semantic static state markers and standalone-safe journey summaries.

### Deferred

- Scheduler-specific atomic Work Plan, dynamic Assignment `plan_changed` projection, managed Project Center details and cross-process fencing are not part of the standalone release contract.

## 0.1.1 - 2026-08-24

### Added

- Workspace-native Project binding with idempotent initialization under `<workspace>/j4agent/`.
- Project Center overview, activity, delivery and end-to-end development-journey readers.
- A centered Project Center dialog with seven navigation destinations and a shared Work Item inspector.

### Changed

- Project identity now follows the current DSH Workspace instead of creating a second browser-owned Project.
- The J4Agent sidebar launcher now opens the Project Center dialog instead of a right-side panel.
- Shared sidebar footer actions stack vertically in expanded mode, while the collapsed J4Agent launcher uses a compact icon.
- DSH compatibility baseline is `0.1.1-rc.2`.

## 0.1.0 - 2026-08-23

First public release for local, single-user DSH.

### Added

- Jira-like Project and Work Item facts with workflow and revision CAS.
- Workspace and repository bindings without treating external IDs as Project identity.
- Comments, decisions, activities, safe attachment metadata and contextual Session bindings.
- Milestones, releases, release scope and explicit verification records.
- SQLite persistence and schema migration through Task Graph schema v4.
- Deterministic dependency graph, Ready Set, diagnostics and cycle rejection.
- Six Workforce-facing Host services and two model-facing Agent tools.
- DSH-native Web panel and loopback RPC for the core human journey.
- One-command G1-G6 release gate for engineering, coverage, lifecycle, package, DSH and browser checks.

### Known limitations

- Local single-user operation only; J4Agent does not schedule or spawn Agents.
- Web dependency editing and advanced reporting are not included.
- Long-running multi-process stress and backup/corruption recovery remain follow-up work.
