[016] Notes Application (MVP)

[iliall]

Overview

A single-user notes application for quickly creating, editing, and viewing text notes. All notes belong to a single shared space protected by a fixed password.

Build this as a Python backend service with no UI; expose the functionality below through an HTTP API.

Credentials: Password is exactly my-notes-are-mine (case-sensitive, not changeable).

Persistence: Notes persist across server restarts.

Constraints:

• No organization features (folders, tags, pinning)
• No rich text formatting (only plain text with line breaks)
• No attachments, exports, or imports
• No multi-user accounts or sync

Password Protection

Every request must include the password.

Behavior:

• Missing password is rejected with an error ("Password is required" or similar)
• Wrong password is rejected with an error ("Incorrect password" or similar)
• No note data (titles, previews, counts, timestamps) is accessible without the correct password

Notes List

All notes can be listed.

Each note in the list includes:

• Title: First non-empty line of the note body, trimmed of whitespace. If body is empty/whitespace-only, show placeholder like "New Note"
• Preview: Single-line snippet from the body following the title line, truncated with ellipsis if long
• Timestamp: Last edited time in exact format YYYY-MM-DD hh:mm (24-hour, UTC)

Sorting: Notes sorted by last edited timestamp, descending (most recent first).

Create & Edit Note

Creating: Creating a note starts it with an empty body.

Editing: A note's body can be updated. Line breaks preserved.

• The last edited timestamp updates on each save

Empty notes: A note with empty body remains valid and listed (uses placeholder title).

Search

Notes can be filtered by a search query.

Matching: Case-insensitive substring match against title OR body.

Behavior:

• Filtered results maintain last-edited-time sort order
• Empty query shows all notes

Delete Note

Notes can be deleted.

Behavior:

• Deletion immediately removes the note from all listings and search results
• Deletion is permanent; no trash, undo, or recovery

Note Identity

Each note has a stable identifier that returns the same note when requested again. Access to individual notes respects the password protection.
