# Fix Reader Bugs: Covers, Indexing, TOC, Cache Deletion

**Date:** 2026-03-08
**Commit:** `022f519` on `mod/master-resync`

## Task Description

Fixed four bugs reported after the upstream sync feature restoration:

1. **Placeholder cover text rendering** — only first letter of each word visible
2. **Silent indexing indicator** — wrong timing (shown on first page, not during actual indexing) and icon positioned above the status bar
3. **Long-press confirm for TOC** — immediately selected the first chapter upon button release
4. **Book cache deletion from home screen** — showed "no open books" and required double confirm press

## Changes Made

### lib/PlaceholderCover/PlaceholderCoverGenerator.cpp
- Added `#include <EpdFontData.h>` for `fp4::toPixel()`
- Fixed `renderGlyph()`: `glyph->advanceX` is 12.4 fixed-point, not pixels — was advancing cursor ~16x too far, causing only the first character of each word to be visible
- Fixed `getCharAdvance()`: same fixed-point conversion needed for space width calculation in word wrapping

### src/activities/reader/EpubReaderActivity.cpp
- Removed `silentIndexNextChapterIfNeeded()` call from `loop()` (line 385) — this blocked the UI before render, preventing the indicator from ever showing. The backup branch only called it from `render()`, after the page was drawn.
- Fixed indexing icon Y position: changed `textY - kIndexingIconSize + 2` to `textY + 2` to align within the status bar alongside battery/text
- Passed `consumeFirstRelease` flag when creating chapter selection activity from long-press path

### src/activities/reader/EpubReaderChapterSelectionActivity.h/.cpp
- Added `ignoreNextConfirmRelease` member and `consumeFirstRelease` constructor parameter
- In `loop()`, consumes the first Confirm release when opened via long-press, preventing immediate selection of the first TOC item

### src/activities/home/HomeActivity.cpp
- In `openManageMenu()` callback: reset `ignoreNextConfirmRelease = false` to fix double-press bug
- Replaced `recentBooks.clear()` with `loadRecentBooks()` to reload remaining books from persistent store after deletion

## Follow-up Items

- Test all four fixes on device to verify correct behavior
- Verify placeholder covers render full title/author text at both thumbnail and full-cover sizes
