Profile details: personal user notes with markdown support

[hessius]

Overview

Add a personal notes field to the profile detail view where users can record grind settings, dialling notes, and other observations. Rendered as markdown. Stored in MeticAI history — not exported with the profile, not visible to others.

Background

The Meticulous profile JSON already contains a notes field set by the profile author (e.g., recommended parameters). This feature is distinct: it's your own private notes, independent of the profile's built-in metadata. Think: a sticky note you attach to a profile card.

Features

1. User Notes Field

Displayed in the profile detail view, below the AI description / profile breakdown:

• Empty state: "Add your notes" placeholder tap-target
• View state: notes rendered via MarkdownText (already exists)
• Edit state: MarkdownEditor component (built in Shot annotations: markdown comments, star rating, and persistent metadata #179) with 2000-char limit
• Edit/Preview tabs in the editor (MarkdownEditor is the shared component)
• Auto-save on blur or explicit Save tap
• Character counter near limit

2. Storage

Stored as user_notes on the MeticAI history entry — separate from ProfileData.notes (the author's built-in profile notes).

Backend: add user_notes: Optional[str] to the history entry schema in history_service.py and persist in profile_history.json.

No separate file — notes are part of the history entry to keep reads cheap.

3. Not Exported

User notes are not included in profile JSON exports or PNG exports. They live only in MeticAI history. If a profile is deleted from MeticAI history, notes are deleted with it.

4. AI Description Toggle on Import

When a profile is imported (manually or during sync from #182), offer an opt-in toggle:

"Generate AI summary for this profile"

• Default: off
• When on: calls existing Gemini analysis endpoint, stores result as profile description
• Shows token cost warning (same copy as existing advanced.detailedKnowledgeWarning)
• This toggle also appears on the profile detail view for profiles that have only a static description ("generated without AI assistance") — a "Generate AI Summary" button that triggers on demand

This toggle is surfaced here (not as a separate issue) because it's the natural complement to the notes feature: both are about enriching a profile's metadata as a user.

API Changes

Method	Endpoint	Purpose
PUT	/api/history/{history_id}/notes	Save or clear user notes
GET	/api/history/{history_id}	Already returns notes once user_notes field added

Shared Component: MarkdownEditor (from #179)

MarkdownEditor is built first in #179. This issue consumes it:

<MarkdownEditor
  value={userNotes}
  onChange={setUserNotes}
  onSave={saveNotes}
  placeholder="Grind: 11 clicks. Dose: 18g. Pull time: 28s…"
  maxLength={2000}
  label="Your notes"
/>

#179 must be completed (at least the MarkdownEditor component) before UI work on this issue begins.

Notes vs Profile Author Notes

Field	Source	Who sets it	Exported	Stored
ProfileData.notes	Profile JSON	Profile author	✅ Yes	On machine
user_notes	MeticAI history	You	❌ No	MeticAI only

Both can coexist in the detail view. Display the author's ProfileData.notes (if non-empty) in a clearly labelled read-only block above the editable "Your notes" section.

Acceptance Criteria

• user_notes field added to history entry schema and persisted
• PUT /api/history/{id}/notes endpoint implemented
• Editable notes section in profile detail view
• Notes render via MarkdownText, edit via MarkdownEditor
• Empty-state placeholder shown when no notes exist
• Character limit enforced (2000) with counter
• Notes not included in profile JSON or PNG export
• Profile author's ProfileData.notes shown separately (read-only) if present
• "Generate AI Summary" button shown for profiles with static-only descriptions
• MarkdownEditor from Shot annotations: markdown comments, star rating, and persistent metadata #179 is used (not reimplemented)

Implementation Status: ✅ Complete

PR #262 fully implements profile notes:

Backend:

• Added notes and notes_updated_at fields to history entry
• Added update_entry_notes() and get_entry_by_id() functions to history_service.py
• Added GET /api/history/{entry_id}/notes endpoint
• Added PATCH /api/history/{entry_id}/notes endpoint

Frontend:

• Added "Personal Notes" section to ProfileDetailView in HistoryView.tsx
• Reuses MarkdownEditor component from Shot annotations: markdown comments, star rating, and persistent metadata #179 (shot annotations)
• Auto-save on blur with toast feedback
• Notes hidden during image capture export

Translation:

• Added English strings for notes UI (labels, placeholder, save feedback)
