docs(api): real progress endpoint contract; remove nonexistent-endpoint docs
The progress documentation described GET/POST /api/progress/:id — endpoints that do not exist in the router — while the endpoint every client actually uses (GET/PUT/DELETE /api/media-items/:id/progress) had no field-level docs at all. New: - progress/position-contract.md: the canonical position model — server as position authority, the three-tier submission (percentage / context_text / epubcfi), ingest verification and healing, the restore handles, the OPF spine numbering hazard (canonical CFI spine steps include linear="no" items; clients resolve documents by anchor_href and land by css_selector + char_offset, never by spine step), the offset currencies (UTF-16 at the wire, runes internal), and context_text rules. - progress/get_media_progress.md and update_media_progress.md: the real endpoints with full field tables, conditionality of the restore handles, the first-page anti-clobber guard, and healed-response semantics. - progress/delete_media_progress.md: the real DELETE route. - koreader/sync_progress.md and koreader/get_metadata.md rewritten to the actual payloads: the plugin sends a single-book array whose "epubcfi" field is a CRE xpointer; the metadata response navigates via koreader_xpointer (canonical CFI converted back to CRE), with page as the canonical locator for fixed-layout books. Removed: the five files documenting the nonexistent /api/progress/:id GET/POST/DELETE endpoints. Kept get_progress_history.md (that route exists). The legacy developer/api-reference.md and the indexed api/api-reference.md progress sections now match the wire and link the new docs; the duplicate "Universal Progress" section points at Reading Progress.

# Sync Progress
|
||||
|
||||
Sync reading progress from KOReader device.
|
||||
Push reading progress from a KOReader device.
|
||||
|
||||
**Endpoint**: `POST /api/sync/koreader/progress`
|
||||
**Auth**: Required (Device authentication)
|
||||
**Auth**: Required (Device authentication — `Authorization: Bearer {device_token}`)
|
||||
|
||||
## Device Authentication
|
||||
|
||||
This endpoint requires device authentication (not user JWT). Devices authenticate using their device credentials.
|
||||
This is the device-native tier of the [Position
|
||||
Contract](../progress/position-contract.md): 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 |
|
||||
| --------- | ------------- | -------- | ------------------------- |
|
||||
| device_id | string (UUID) | Yes | Device UUID |
|
||||
| progress | array | Yes | Array of progress objects |
|
||||
| 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`. |
|
||||
|
||||
### Progress Object
|
||||
### Book Object
|
||||
|
||||
| Field | Type | Required | Description |
|
||||
| ----------- | ------- | -------- | ---------------------------------- |
|
||||
| book | string | Yes | Book identifier (filename or UUID) |
|
||||
| percent | float | Yes | Progress percentage (0-100) |
|
||||
| page | integer | No | Current page number |
|
||||
| total_pages | integer | No | Total pages in document |
|
||||
| date_read | string | No | ISO 8601 timestamp of last read |
|
||||
| updated_at | string | Yes | ISO 8601 timestamp |
|
||||
| Field | Type | Required | Description |
|
||||
| ----- | ---- | -------- | ----------- |
|
||||
| `uuid` | string (UUID) | No | Bookhoard UUID, once the device has linked the book via [Resolve Book](resolve_book.md). |
|
||||
| `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 }`. |
|
||||
|
||||
