# Session Summary - 2026-01-05

**Author**: Équipe 4NK
**Date**: 2026-01-05

## Overview

This document summarizes all modifications and implementations completed during this development session, focusing on object identification, caching, payment systems, A5 pages, and payment notes.

## Major Features Implemented

### 1. Object Identification System

**Objective**: Implement a comprehensive object identification system with `id`, `hash`, `version`, and `index` fields for all objects.

**Implementation**:
- ID format: `<hash>_<index=0>_<version=0>`
- All objects now have: `id`, `hash`, `version`, `index`
- Hash generation using SHA-256 from canonical object representation
- Index management for duplicate hash handling
- Version management for object updates

**Files Modified**:
- `types/nostr.ts`: Added fields to all object interfaces
- `lib/urlGenerator.ts`: Added `buildObjectId` and `parseObjectId` functions
- `lib/hashIdGenerator.ts`: Hash generation for all object types
- `lib/nostrEventParsing.ts`: Updated to extract and construct new ID fields
- `lib/objectCache.ts`: Updated IndexedDB cache to support new ID structure

**Routes**: All object routes now use the new ID format: `https://zapwall.fr/<type>/<id>`

### 2. IndexedDB Caching System

**Objective**: Implement per-object-type caching in IndexedDB with settings storage and last sync date tracking.

**Implementation**:
- Separate IndexedDB stores for each object type (author, series, publication, review, purchase, sponsoring, review_tip)
- Settings store (excluding keys) for platform configuration
- Last synchronized day tracking for background sync resumption
- Database migration system (DB_VERSION incremented to 2)
- New indexes: `hash`, `index` for efficient lookups

**Files Modified**:
- `lib/objectCache.ts`: Complete rewrite with new structure
- `components/CacheUpdateManager.tsx`: User-facing cache update button

**Features**:
- Cache per object type
- Settings cache (excluding sensitive keys)
- Last sync date tracking
- Cache clearing and re-synchronization

### 3. Payment Objects Extension

### 5. Optional Text Fields

**Objective**: Add optional plain text messages to reviews, review tips, and sponsoring.

### 6. Review, Review Tip, and Sponsoring Forms

**Objective**: Create user-facing forms for creating reviews, sending review tips, and sponsoring authors.

**Implementation**:
- `ReviewForm`: Create reviews with optional title, required content, optional text
- `ReviewTipForm`: Send tips to reviewers with optional text message
- `SponsoringForm`: Sponsor authors with optional text message (Bitcoin mainnet)

**Files Created**:
- `components/ReviewForm.tsx`
- `components/ReviewTipForm.tsx`
- `components/SponsoringForm.tsx`

**Files Modified**:
- `components/ArticleReviews.tsx`: Integrated review and tip forms
- `pages/series/[id].tsx`: Integrated review display
- `pages/author/[pubkey].tsx`: Integrated sponsoring form
- `public/locales/fr.txt` and `public/locales/en.txt`: Added translations

### 7. Full-Width Layout

**Objective**: Allow the site to take up the full screen width.

**Implementation**:
- Removed `max-w-*` constraints from all pages
- Updated layout classes across the application

**Files Modified**:
- All page components (`pages/*.tsx`)
- `components/HomeView.tsx`

### 8. Funding Gauge Priorities

**Objective**: Set priorities for funding gauges: Priority 1 for AI, Priority 2 for Anchoring.

**Implementation**:
- Updated `components/FundingGauge.tsx` to display two gauges with priorities
- Added translations for certification gauge

**Files Modified**:
- `components/FundingGauge.tsx`
- `public/locales/fr.txt` and `public/locales/en.txt`

### 9. Payment Notes System

**Objective**: Create explicit payment notes (kind 1) for all confirmed payments with project tags.

**Implementation**:
- Extended tag system with `'payment'` type
- Created `PaymentTags` interface
- Three publication functions: `publishPurchaseNote`, `publishReviewTipNote`, `publishSponsoringNote`
- Integration with payment confirmation flows
- Zap receipt query utilities

**Files Created**:
- `lib/paymentNotes.ts`: Payment note publication functions
- `lib/zapReceiptQueries.ts`: Zap receipt query utilities

**Files Modified**:
- `lib/nostrTagSystemTypes.ts`: Added `PaymentTags`
- `lib/nostrTagSystemBuild.ts`: Added `buildPaymentTags`

**Documentation**: See `docs/payment-notes-system.md` for detailed documentation.

## Tag System Verification

Verified that all note creation functions use the `buildTags` helper:
- `buildSeriesEvent`: ✅ Uses `buildTags`
- `buildReviewEvent`: ✅ Uses `buildTags`
- `buildAuthorPresentationEvent`: ✅ Uses `buildTags`
- `buildPreviewTags`: ✅ Uses `buildTags`
- Zap requests: ✅ Include `kind_type` and relevant tags

## Technical Details

### Object ID Format

```
id: <hash>_<index>_<version>
```

- `hash`: SHA-256 hash of canonical object representation
- `index`: Index for duplicate hashes (default: 0)
- `version`: Version number for updates (default: 0)

### IndexedDB Schema

- Stores: `author`, `series`, `publication`, `review`, `purchase`, `sponsoring`, `review_tip`, `settings`
- Indexes: `hash`, `index`, `version`, `hidden`
- Version: 2 (migrated from 1)

### Payment Flow Integration

1. **Purchase**: Zap receipt → Content delivery → Payment note publication
2. **Review Tip**: Zap request → Zap receipt (via Alby) → Payment note publication (to be integrated)
3. **Sponsoring**: Bitcoin transaction → Verification → Tracking → Payment note publication (to be integrated)

## Internationalization

Added translations for:
- A5 pages (`page.*`)
- Reviews (`review.*`)
- Review tips (`reviewTip.*`)
- Sponsoring (`sponsoring.*`)
- Funding gauge priorities
- Common optional field label

## Testing Considerations

- All new code compiles without TypeScript errors
- Linter checks pass
- No fallback mechanisms (as per project rules)
- Error handling with logging
- Non-blocking payment note publication

## Known Limitations

1. **Review Tip Notes**: Automatic publication after zap receipt confirmation not yet fully integrated
2. **Sponsoring Notes**: Requires payer information at transaction submission time (currently not captured)
3. **Payment History UI**: Not yet implemented (payment notes are published but not displayed in UI)

## Next Steps

1. Complete review tip note publication integration
2. Improve sponsoring note publication with payer information capture
3. Implement payment history UI
4. Add payment aggregation queries
5. Create payment search functionality
