Kobo emulation + KOReader calibre-compatible surface backfilled with
device-token auth; collections reorder + update_rule created.
Claude registry: 12 entries. kobo/koreader emulation endpoints all bind
arbitrary protocol POST bodies (markup/bookmark/gettests/sync-from-server,
koreader progress/bookmarks) — registered as AnyJSONObject, not bodyless as
first drafted. Initialization returns the library sync payload, not the init
response.
Contract correction in update_rule.md: the route is SetRuleEnabled ({enabled}
required -> {collection_id, is_smart}); Beam's draft invented rule-field
updates. Reordered response/status: {item_ids} -> {status: reordered}.
make test 9/9.

Sync Progress
Push reading progress from a KOReader device.
Endpoint: POST /api/sync/koreader/progress
Auth: Required (Device authentication — Authorization: Bearer {device_token})
This is the device-native tier of the Position
Contract: the KOReader payload carries
a CRE xpointer and the server converts it to the canonical standard CFI,
verifies it against the submitted context_text, and heals it on
mismatch — exactly like every other client.
Request Body
| Field | Type | Required | Description |
|---|---|---|---|
books |
array | Yes | One book object (the reference client sends a single-element array). |
sync_mode |
string | No | immediate (default) or manual. |
Book Object
| Field | Type | Required | Description |
|---|---|---|---|
uuid |
string (UUID) | No | Bookhoard UUID, once the device has linked the book via Resolve Book. |
sha256 |
string | Yes | File content hash (64 hex chars) — the primary book identity. |
title |
string | No | Document title. |
authors |
array | No | Author names. |
percentage |
float | Yes | Position as a fraction of the book (0..1). |
context_text |
string | No | Up to 100 whitespace-normalized chars from the current position — enables the server's verification/healing. Strongly recommended. |
page |
int | No | Current page (fixed-layout books). |
total_pages |
int | No | Page count (fixed-layout books). |
epubcfi |
string | Reflowable only | A CRE xpointer (/body/DocFragment[N]/body/...), not a CFI — the field name is historical. Fixed-layout books must omit it and carry their position in page/total_pages. |
file_path |
string | No | Device-local file path (informational). |
device_info |
object | No | { koreader_version, device_model }. |
