Uri Tauber 5ba1d5747f fix: EndOfBookOptions fails to compile
ActivityManager.h forward-declares Activity but holds
std::unique_ptr<Activity> members. Instantiating that unique_ptr's
destructor requires the complete type, so any TU including
ActivityManager.h without Activity.h fails to compile.

Include Activity.h directly. Adding it to ActivityManager.h instead does
not work: Activity.h depends on HomeMenuItem, which ActivityManager.h
defines.

Thomas Symalla 9fe4dc5e38 feat: Add option to switch behavior for "back to browser / home" in Reader activity (#2366)
## Summary

It would be nice to switch back to the file list from an Reader activity
via a short back button press. This change adds an Reader option to
switch the default behavior, so a short back button press in the Reader
activity can now go back to the file list, and a long press on back goes
back to the home view. This does a fair bit of refactoring, introducing
a new constant for the ms limit.

* **What changes are included?**

- Changes to the translation
- Additional global Reader option 
- Refactoring of the back button behavior in the Reader activity

Justin Mitchell b1d037569b feat: Add kosync user registration and switch to crosspoint-sync server (#2587)
Implements createUser() endpoint to allow account creation via the
KOSync protocol. Changes default sync server from sync.koreader.rocks to
sync.crosspointreader.com with migration logic to preserve existing
users' server settings. Extends sync protocol to include position data
(spine index, page numbers, xpath) that crosspoint-sync supports while
remaining compatible with standard kosync servers.

Justin Mitchell 98118d6e24 Improve heap management in EPUB rendering
Fix CPU pinning by tracking buildHeapPaused state when background build is blocked. Re-check heap gate after acquiring lock to handle race conditions where rendering expands glyph buffers. Refine plane buffer allocation to check both free heap and max contiguous block, preventing fragmentation issues that could cause OOM during page renders. Skip async refresh for image pages since they use blocking double-FAST path.

a4ac3b2788 feat: add smart KOReader progress sync (#2192)
## Summary

Make KOReader progress sync a one-click flow for common cases while
keeping the existing manual mode available.

### Changes

- Add a **Sync Behavior** setting:
  - **Smart sync** for new configurations
  - **Ask every time** for manual control
- Preserve **Ask every time** when migrating an existing credential file
that predates this setting.
- In Smart mode:
  - upload local progress when no remote record exists;
  - show a short confirmation when already synced;
  - upload when local progress is further ahead;
  - apply remote progress when remote progress is further ahead.
- Probe both KOReader document-matching hashes before making the Smart
decision, while keeping uploads on the user's configured matching
method.
- Auto-return after successful Smart terminal states, with Back/Confirm
still available.
- Persist the setting alongside the current credential, matching-method,
and send-metadata fields.
- Document both behaviors in the user guide.

## Additional context

This pairs well with #2189 (smart Wi-Fi auto-connect), but does not
depend on it. It does not add background Wi-Fi or passive network
detection; sync is still triggered by the user from the reader menu.

Smart sync uses the furthest progress because CrossPoint does not
currently persist local progress timestamps. Users who prefer explicit
conflict resolution can select **Ask every time**.

## Verification

- `git diff --check`
- `platformio check --fail-on-defect low --fail-on-defect medium
--fail-on-defect high` — no defects
- `platformio run -e default` — firmware build successful
- The original implementation was manually smoke-tested on an X4 device.

Tom-Inge LarsenandClaude Opus 4.8 e4d3981469 fix(reader): correct slider side-button direction and legend on X3 (#2402) (#2428)
## Summary

* **What is the goal of this PR?** Fixes #2402. On the X3, the "Time to
Sleep"
picker's 5-minute side buttons were inverted (left increased, right
decreased)
  and the on-screen legend didn't match the physical buttons.
* **What changes are included?**
  * Flip the large-step (±5 min) direction on X3 so the left side button
decreases and the right increases, matching the layout. X4 is unchanged.
* Add a device-specific step-hint string
(`STR_SLEEP_TIMER_STEP_HINT_X3`)
selected via `gpio.deviceIsX3()`. X3 shows `+/-: 1 min Side buttons: 5
min`;
    X4 keeps the original `Left/Right: 1 min  Up/Down: 5 min`.
* Same fix applied to both slider pickers that read the raw up/down side
    buttons: the Time-to-Sleep picker and the "Go to %" picker
(`EpubReaderPercentSelectionActivity`), each with its own X3 hint string
    (`STR_SLEEP_TIMER_STEP_HINT_X3`, `STR_PERCENT_STEP_HINT_X3`).

## Additional Context

* **Root cause:** the X3's side buttons sit one on each edge of the
screen
(power on top), whereas the X4 has a vertical up/down rocker on the
right
edge. So `BTN_UP` is physically the *left* button on X3 but the *top*
button
  on X4. The picker mapped up→+5 / down→−5 unconditionally, which reads
naturally on the X4 rocker but inverted on the X3's left/right buttons.
The
  static legend ("Up/Down: 5 min") had the same X3-only mismatch.
* The codebase already detects the device at runtime and handles this
layout
difference elsewhere (e.g. `LyraTheme::drawSideButtonHints` draws "Up on
left,
Down on right" for X3), so this reuses the same `gpio.deviceIsX3()`
signal.
* Swept the codebase for other side-button sliders:
`ClockOffsetActivity` already
uses the `Next/Previous` (`ButtonNavigator`) abstraction, which resolves
to
left=decrement / right=increment on X3, so it needs no change. List/page
navigation (Wi-Fi, KOReader sync, BMP viewer) and the keyboard cursor
are also
unaffected. The two slider pickers above were the only ones using raw
up/down.
* **X4 is untouched** — same direction, same legend wording as before.
* **Tested on X3 hardware:** left side button now decreases, right
increases, and
  the legend matches. X4 not yet tested on device (no unit on hand); its
  behaviour and strings are unchanged from master.
* **Translations:** the new `STR_SLEEP_TIMER_STEP_HINT_X3` and
`STR_PERCENT_STEP_HINT_X3` were added to all 26 languages, but the
non-English
  ones are AI-generated and would benefit from a native-speaker pass —
particularly Hebrew (RTL ordering with a leading `+/-`), Kazakh, and
Vietnamese.

Uri Tauber a09aef0889 fix: Optimize Bookmark Rendering by Removing XPath Lookup (#2417)
## Summary

fix #2414 

### Root Cause

`updateBookmarkFlag()` was introduced in commit 1db1442 and is executed
on every render (every page turn). The function calls:

`ProgressMapper::toSavedProgress()`
→ `ChapterXPathResolver::findXPathForProgress()`

This path decompresses the current EPUB section content twice:

1. To count visible characters.
2. To resolve the corresponding XPath.

For larger sections (e.g. ~133 KB decompressed content), this adds
approximately **1 second of I/O overhead per page turn**, with the cost
increasing as chapter size grows.

### Fix

`updateBookmarkFlag()` only needs to determine whether a bookmark falls
within the currently displayed page range.

The required information is already available during rendering:

* `currentPage`
* `section->pageCount`
* `currentSpineIndex`

Instead of converting the current location to a saved progress object
(and resolving an XPath), the implementation now computes the current
page's progress range directly and compares bookmark percentages against
that range.

This is effectively the same percentage-based matching logic already
used as a fallback in `bookmarkMatchesProgress()` when XPath matching is
unavailable.

Justin Mitchell f6e59aab72 feat: Add displayGrayscaleBase method for differential refresh
(#2334)

Introduces a new display method that prepares the framebuffer as a base
frame for grayscale overlays. On X3 panels, this uses the OEM
differential base waveform (AA-pre-BW) without forcing a resync. Other
panels fall back to normal display with configurable refresh mode.

Uri TauberandJulia Nguyen 1db1442319 fix: several bookmarks UX improvments (#2372)
## Summary

This PR enhances the EPUB reader's bookmark system with two
complementary improvements: a per-page bookmark indicator icon and
toggle behavior on the existing long-press action.

---

### What Changed

**Bookmark Toggle (was: add-only)**

The long-press Confirm action now toggles bookmarks rather than always
adding. `addBookmark()` checks whether a bookmark with the same xpath
already exists in the in-memory cache:
- If found → removes it and shows "Bookmark removed."
- If not found → adds it and shows "Bookmark added."

A new `STR_BOOKMARK_REMOVED` translation string was added to support the
removal message.

**Bookmark Icon Indicator**

A `BookmarkIcon` is now drawn at the top-right corner of the page
whenever the current page has a bookmark. `updateBookmarkFlag()` is
called at render time to determine whether the current page is
bookmarked.

**In-Memory Bookmark Cache**

Bookmarks are now loaded into `cachedBookmarks` on `onEnter()` rather
than being re-read from disk on every toggle. All subsequent add/remove
operations work against this cache and flush to disk, avoiding redundant
file reads on each bookmark action.

**Faster bookmarks list**

Previously, calculating "page X/Y" for each entry required decompressing
the entire spine item. We now persist `si`/`pc`/`pp` (spine index, page
count, and page progress) in the bookmark JSON when saving, and restore
them when loading. This avoids the expensive `toCrossPoint()` loop in
`onEnter()`, significantly reducing the cost of initializing the
bookmarks list.

---

### Files Changed

- `EpubReaderActivity.cpp` — `addBookmark()` toggle logic,
`updateBookmarkFlag()` (new), icon rendering in `renderContents()`,
cache initialization in `onEnter()`
- `EpubReaderActivity.h` — new fields: `currentPageBookmarked`,
`bookmarkRemoved`, `cachedBookmarks`; new method declaration
`updateBookmarkFlag()`

Pedro CardosoandClaude Opus 4.8 5e990b3991 fix: prevent progress.bin corruption from interrupted writes (#2275) (#2305)
## Summary

* **What is the goal of this PR?**
Fixes #2275. A book could get stuck reopening on an old page, with
progress no
longer saving and neither "Delete Book Cache" nor "Clear Reading Cache"
able to
fix it. Root cause: `progress.bin` was written truncate-in-place, so an
interrupted write (power loss, or a crash mid-SPI during sleep) left it
with a
broken FAT cluster chain that the firmware could neither rewrite nor
delete —
  recovery required `fsck`/manual deletion on a host PC.

  Confirmed in the SDK: `SDCardManager::openFileForWrite` opens with
`O_RDWR | O_CREAT | O_TRUNC`, so the canonical file is zeroed before the
few
progress bytes are rewritten — exactly the window that corrupts the FAT
chain.

* **What changes are included?**
  * New shared helper `ProgressFile::writeAtomic()`
    (`src/activities/reader/ProgressFile.h`): writes progress to
    `progress.bin.tmp`, flushes and closes it, then `remove`s the old
`progress.bin` and `rename`s the temp into place. An interrupted write
now
only ever damages the throwaway temp; the canonical file is never torn.
  * All three readers route their progress saves through the helper:
EPUB (`EpubReaderUtils.h`), `TxtReaderActivity`, `XtcReaderActivity` —
they
    all shared the identical vulnerable pattern.
* Minor: `EpubReaderUtils::saveProgress` now takes `const Epub&` (clears
a
    cppcheck `constParameterReference` finding).

## Additional Context

* **Crash-safe, not metadata-atomic.** On FAT the replace is `remove` +
`rename`
(two directory ops; SdFat's `rename` won't overwrite, hence
remove-first). A
crash between them leaves *neither* file, which reads as "no saved
progress" on
next launch — a harmless reset to an old page, never a
corrupt/unclearable file.
  The guarantee is that `progress.bin` is never half-written.
* **Prevents, does not repair.** This stops new corruption on healthy
cards. It
cannot fix an already-corrupted `progress.bin` (removing it may itself
fail at
the FAT level) — those still need `fsck`/manual deletion, as in the
issue's
  workaround.
* **Known follow-up (out of scope here):** a crash *while writing the
temp* can
leave an orphan `progress.bin.tmp`. It's harmless and self-healing (the
next
save overwrites it, and it never blocks reading progress), but a
boot-time
  orphan-`.tmp` cleanup would be a tidy follow-up.
* **Focus areas for review:** the close-before-rename ordering in
  `ProgressFile.h` and the remove-before-rename rationale.

## Verification

* `./bin/clang-format-fix` — clean
* `pio check --fail-on-defect low --fail-on-defect medium
--fail-on-defect high` — no defects
* `pio run` — SUCCESS (RAM 30.9%, Flash 78.8%; footprint essentially
unchanged)
* Tested on a **Xteink X4** device: open book, turn pages, sleep/exit,
reopen —
  progress now restores to the navigated page across all three readers
  (EPUB / TXT / XTC).

darkbubluandClaude Opus 4.7 d4069aeae5 feat: long-press Confirm launches KOReader sync from EPUB (#1808)
## Summary
- Hold the menu (Confirm) button for ≥1s while reading an EPUB to launch
the existing `KOReaderSyncActivity` directly — replaces the three-step
path (open reader menu → scroll to Sync → confirm) with a single
gesture.
- Reuses `ReaderUtils::GO_HOME_MS` (same 1s threshold used by long-press
Back) and the existing `KOREADER_STORE.hasCredentials()` guard.
- Adds a Controls picker **"Long-press Menu"** (`longPressMenuFunction`,
default **Bookmark**) that **cycles through the available functions**
bound to the long-press gesture: `KOSync → Disabled → Bookmark`. The
field name and `LONG_PRESS_MENU_FUNCTION` enum are intentionally general
so future actions (dictionary lookup, table of contents, etc.) can be
appended without another schema migration. The setting is **not** a
binary toggle.
- Existing menu Sync entry still works — both call sites share one
extracted helper (`launchKOReaderSync`); no logic duplication.
- Short-press Confirm release is gated on duration so the reader menu
does not also open after a long press that *acts*, mirroring the
existing long-press Back pattern.
- **No-credentials fall-through:** `launchKOReaderSync()` now returns
whether it acted. When the function is set to KOSync but no KOReader
credentials are stored, the long-press is a no-op that **falls through
to open the reader menu** — so the menu stays reachable instead of the
hold silently swallowing the gesture. The release is only suppressed
when sync actually launched or surfaced a save error.

## Test plan
- [x] `pio run` succeeds clean for the `default` ESP32-C3 environment.
- [x] On-device, value **KOSync**, valid KOReader credentials:
long-press Confirm ≥1s → sync screen launches; get + update progress
return HTTP 200; release does **not** also open the reader menu; returns
to the same page.
- [x] On-device, value **KOSync**, **no** credentials: long-press
Confirm falls through and **opens the reader menu** (regression fix);
short-press also opens the menu.
- [x] On-device: menu → Sync still launches the same screen (shared
helper) and syncs (200/200).
- [x] On-device, value **Bookmark**: long-press drops a bookmark and
does **not** also open the menu.
- [x] On-device, value **Disabled**: long-press Confirm opens the menu
on release; no sync, no bookmark.
- [x] On-device: long-press Back still goes to the file browser
(unchanged path).
- [x] Heap: epub is released before the TLS handshake (frees ~16 KB);
min free heap stayed ~84 KB during sync, well above the safe floor. No
panics/OOM across the session.

Vadim KaushanandClaude Sonnet 4.6 213972badc fix: navigate to TOC anchor when selecting sub-chapters (#1981)
Chapter selection previously only used the spine index, causing
navigation to always land on page 0 of the spine item. Sub-chapters that
share a spine file but differ by anchor (e.g. `chapter.xhtml#sec2`) were
silently ignored. Now the TOC anchor is passed through `ChapterResult`
and applied via the existing `pendingAnchor` mechanism.

## Summary

* This PR implements navigation to sub-chapters which didn't work
correctly previously. If a sub-chapter of the current top-level chapter
was selected, nothing happened. If a sub-chapter of another top-level
chapter was selected, reader switched to the beginning of the top-level
chapter.
* In addition, chapters now always start from a new page. This fixes
anchor to page calculation for the cases when the actual chapter content
doesn't fit on the page where the corresponding ToC anchor was found.

## Additional Context

* I might misuse `pendingAnchor` here which was previously used for
footnote navigation, please double check. I'm open to suggestions for
improvements.
* Note that the chapter selected by default when
`EpubReaderChapterSelectionActivity` opens is still wrong. I'm going to
fix this separately. This PR addresses only navigation to the selected
chapter.
* I tested this PR on my X4 and verified that navigation to a different
sub-chapter works correctly, both inside and outside the current spine.
* Some of the changes were borrowed from
https://github.com/crosspoint-reader/crosspoint-reader/pull/1455

writeGrayscalePlaneStrip), leaving the BW framebuffer intact. No save,
no
restore; controller RAM is re-synced for the next differential turn
directly
from the live framebuffer.

Three writers honor the active band target so per-band re-rendering
stays cheap
and correct:

- drawPixel (text) redirects writes to the band scratch and clips to it.
- renderCharImpl skips glyphs whose physical y-extent is outside the
band before
the bitmap decode (glyphIntersectsStrip), so the per-band re-render
doesn't
  pay N x glyph decode.
- DirectPixelWriter (images) writes the band scratch via getWriteTarget
instead
  of the framebuffer. Without this, image pixels wrote the live BW frame
directly and cleanup re-synced that corruption, leaving thin outlines
after
  navigating away from an image.

Controller specifics live in the SDK (X4 setRamArea windowing, X3 PTL);
the
reader checks supportsStripGrayscale() and is otherwise
controller-agnostic.

Measured on hardware (X4 and X3, text and images, visually correct):

- Grayscale scratch ~8 KB vs ~50 KB save; largest contiguous free block
held at
  full size during grayscale instead of dropping ~25-32 KB.
- X4 text page about +25 ms/page; X3 page time is dominated by its
intrinsic
  grayscale refresh, not tiling.

Depends on community-sdk #13 (the writeGrayscalePlaneStrip API). The
submodule
bump here points at that branch, so until #13 merges the submodule won't
resolve
from upstream and CI will fail there; keeping this a draft until then.
Will
rebase onto master and re-point the submodule to the merged SDK commit
once #13
lands.

Jeremy Klein 7acc31bc34 fix: silent-reboot on wifi activity exit to clear heap fragmentation (#1908)
WiFi/LWIP/netif teardown scatters long-lived allocations across the
heap, leaving ~50KB of contiguous space unrecoverable without a reboot.

Reboot the SoC on exit from any wifi-using activity to guarantee a clean
heap. An RTC_NOINIT flag survives the reboot and tells setup() to skip
the boot splash and route the user back where they came from:
  - File transfer / Calibre / OPDS / Font download -> home
  - KOReader sync -> currently-open EPUB

Activities check WiFi.getMode() before rebooting, so backing out of the
network mode menu without joining doesn't trigger a cycle. KOSync also
esp_wifi_stop()s after the sync result so the radio is off while the
user reads it; full teardown happens at the reboot.


## Additional Context

The silent reboot skips the booting splash screen - it visibly looks
like a screen refresh. This does cause a disconnection/reconnection blip
for developers actively pulling logs over serial, but `pio device
monitor` and the like successfully reconnect and feed in the early boot
serial.

Zach NelsonandJustin Mitchell b186529120 fix: Prepare SD card font caches from txt reader (#1973)
## Summary

SD card font fixes:
- `TxtReaderActivity` needs to call `renderer.ensureSdCardFontReady` to
build the advance lookup table to support rendering with SD card fonts.
This revealed that `TxtReaderActivity` was inconsistently performing
layout with `getTextWidth`, when the renderer actually uses
`getTextAdvanceX`, which can lead to minor inconsistencies in alignment.
- Avoid allocating one big `allText` string in
`ParsedText::layoutAndExtractLines`. Instead, pass the vector of word
strings directly to `SdCardFont::buildAdvanceTable`, where the algorithm
just needs to iterate codepoints anyway.

Zach Nelson 30b14f2ecf refactor: Removed SdCardFontGlobals.h (#1962)
## Summary

First of several changes to decouple and clean up SD card fonts
integration. This change eliminates SdCardFontGlobals.h:
- Simply declare the `extern SdCardFontSystem sdFontSystem` in
SdCardFontSystem.h.
- `ActivityManager::goToReader` should not care about loading SD card
fonts. Instead do the same work in `ReaderActivity::onEnter`, after the
previous activity has exited and after ReaderActivity has validated the
file path.

Zach Nelson 6f7f4c592a refactor: Eliminated relative path includes (#1961)
## Summary

Relative includes can hide inappropriate dependency relationships. In
this case, I found that lib/KOReaderSync/KOReaderCredentialStore.cpp was
dependent on src/JsonSettingsIO.h -- a lib -> app dependency, the
opposite direction dependencies should flow in this project.

This change replaces all relative includes with root-relative includes,
and corrects the KOReaderCredentialStore dependency by moving its JSON
settings serialization local to the KOReaderSync library.
