+# 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
