 ### Phase 2: ORM Model Implementation
 *   [x] Choose an appropriate ORM (e.g., SQLAlchemy) for Python backend.
 *   [x] Create Python classes (models) representing the `Application` and `VoteRecord` entities, mapping their attributes to database columns.
 *   [x] Define primary keys, foreign keys, data types, and constraints for all columns.
+*   [x] Add timestamp fields (`created_at`, `concluded_at` for `Application`, `voted_at` for `VoteRecord`) to the ORM models.
 *   [x] Implement the relationship between the `Application` and `VoteRecord` models within the ORM.

+# Task 2.7: Display Timestamps in Application Archive
+
+## Goal
+Update the frontend application archive to display the `created_at`, `voted_at`, and `concluded_at` timestamps, providing more detailed information about the application lifecycle.
+
+## Plan
+1.  Update the backend API to include the new timestamp fields in the data transfer objects (DTOs).
+2.  Modify the frontend archive component to display the `created_at` and `concluded_at` timestamps for each application.
+3.  Update the expanded view in the archive to show the `voted_at` timestamp for each individual vote.
+4.  Format the timestamps for user-friendly display.
+
+## Tasks
+
+### Phase 1: Backend API Update
+*   [x] Add `created_at` and `concluded_at` fields to the `ApplicationOut` Pydantic model in `src/projectvote/backend/main.py`.
+*   [x] Add `voted_at` field to the `VoteOut` Pydantic model in `src/projectvote/backend/main.py`.
+*   [x] Ensure the new fields are correctly populated and returned by the `/applications/archive` endpoint.
+
+### Phase 2: Frontend Archive Component
+*   [x] Update the `Archive.tsx` component to fetch the new timestamp fields.
+*   [x] Display `created_at` and `concluded_at` for each application in the main archive view.
+*   [x] In the expanded section for each application, display the `voted_at` timestamp next to each vote.
+*   [x] Implement a function to format the timestamp strings into a more readable format (e.g., "Jan 7, 2026, 10:30 AM").

+# Task 6.4: Database Migrations (Alembic)
+
+## Goal
+Implement a robust database migration system using Alembic to manage schema changes, ensuring smooth upgrades and downgrades for the application's database.
+
+## Plan
+1.  Integrate Alembic into the project.
+2.  Configure Alembic to work with SQLAlchemy models.
+3.  Generate and apply initial migration script.
+4.  Define a process for creating and applying future migrations.
+5.  Automate migration application in the Docker container startup.
+
+## Tasks
+
+### Phase 1: Alembic Integration and Configuration
+Refer to the latest `alembic` documentation at https://alembic.sqlalchemy.org/en/latest/index.html
+*   [x] Add `alembic` to `pyproject.toml` dependencies.
+*   [x] Initialize Alembic environment in the project root (`uv run alembic init --template async --template pyproject alembic`).
+*   [x] Configure `alembic.ini` to point to the correct database URL and SQLAlchemy models.
+*   [x] Modify `migrations/env.py` to import the base metadata from `src/projectvote/backend/models.py`.
+
+### Phase 2: Initial Migration Creation and Application
+*   [x] Generate the first migration script to reflect database schema changes:
+    * Added columns to table ``applications``.
+      1. ``created_at = Column(DateTime, nullable=False, server_default=func.now())``
+      2. ``concluded_at = Column(DateTime, nullable=True)``
+    * Added columns to table ``votes``.
+      1. ``voted_at = Column(DateTime, nullable=True)``
+*   [x] Manually inspect and adjust the generated migration script to include default values for non-nullable columns being added to existing data (e.g., `created_at`).
+*   [x] Apply the migration to the development database (`alembic upgrade head`).
+
+### Phase 3: Docker Integration
+*   [x] Update the Dockerfile or `entrypoint.sh` to automatically run `alembic upgrade head` during container startup to apply any pending migrations.
+*   [x] Ensure the migration step runs before the application server starts.
+
+### Verification
+*   [x] After applying migrations, verify that the database schema is updated correctly.
+*   [x] Test the application with the migrated database to ensure data integrity and functionality.
