+
+## Compressed PFS containers (`.ffpfsc`)
+
+Compressed PFS mode is intended only for nested images. During packing, data is
+zero-padded to a `64 KB` sector boundary, so the compressed PFS should be used
+as an outer container for another image rather than as a direct game-file
+layout.
+
+Recommended layouts:
+- exFAT image inside compressed PFS.
+- Uncompressed PFS image inside compressed PFS.
+
+MkPFS uses zLib compression. Decompression is hardware-assisted, but throughput
+is limited to roughly `150-250 MB/s`. This is about one third of the speed of an
+external USB drive, FFPKG/exFAT images, or about one tenth of the internal drive
+speed. Keep this in mind when choosing which games to pack. Games that read large
+amounts of data or stream textures continuously may stutter.
+
+Use the official [PSBrew/MkPFS](https://github.com/PSBrew/MkPFS) tool to pack
+PFS images.
+
+### Packing an uncompressed PFS image into compressed PFS
+
+First create an uncompressed nested PFS image:
+
+```bash
+mkpfs pack folder --verify --no-compress --no-adjust-output-file-extension --version PS5 --inode-bits 32 \
+  './PPSA07923/PPSA07923-app' \
+  './pfs_image.dat'
+```
+
+Then pack the nested image (**pfs_image.dat**) into a compressed PFS container:
+
+```bash
+mkpfs pack file --verify --version PS5 --inode-bits 32 \
+  './pfs_image.dat' \
+  './PPSA12345.ffpfsc'
+```
+
+After successful packing, the temporary nested image can be removed:
+
+```bash
+rm './pfs_image.dat'
+```
+
+### Packing an exFAT image into compressed PFS
+
+First create a normal exFAT image using one of the methods from
+`Creating an exFAT image`. The nested exFAT image name must keep the `.exfat`
+extension, for example `PPSA12345.exfat`.
+
+Linux:
+
+```bash
+chmod +x mkexfat.sh
+./mkexfat.sh ./PPSA12345-app ./PPSA12345.exfat
+```
+
+Windows:
+
+```cmd
+make_image.bat "C:\images\PPSA12345.exfat" "C:\payload\PPSA12345-app"
+```
+
+The exFAT image must contain the game files at the image root, without an extra
+top-level folder.
+
+Then pack the exFAT image into a compressed PFS container:
+
+```bash
+mkpfs pack file --verify --version PS5 --inode-bits 32 \
+  './PPSA12345.exfat' \
+  './PPSA12345.ffpfsc'

 Recommended only for titles that need external-drive-style compatibility. For general use, prefer `.ffpkg`.
 
+### LVD type-5 / BFS fast-path requirements
+
+ShadowMount attaches `.exfat` through LVD as `img_type=5 (Sv)`, with a 512-byte
+logical sector and a 64 KiB `secondary_unit`. This lets the LVD worker collect
+up to 31 queued, 64-KiB-aligned requests of exactly 64 KiB and
+submit them through `bfs_iosession_rw_sdimg`/`BfsSdimg`. Non-matching requests
+continue through the normal vnode path.
+
+All of the following are required for the kernel to consider that fast path:
+
+- Use `exfat_backend=lvd` (the default). `/dev/mdctl` has no LVD image type or
+  BFS sdimg batching.
+- Store the final `.exfat` file directly on the internal BFS, normally below
+  `/data`. An image on USB/UFS/exFAT/PFS, or an exFAT image nested in compressed
+  PFS, uses the normal path.
+- Format exFAT with a fixed 64 KiB allocation unit. The supplied Linux, macOS,
+  and Windows builders now always use this value, including small-file images.
+- Keep `lvd_exfat_sector_size=512` and do not add an
+  `image_sector=<name>.exfat:65536` override. A logical sector and an exFAT
+  allocation unit are different geometries.
+- Make the image size a multiple of 64 KiB; the supplied builders round it to
+  1 MiB and therefore satisfy this automatically.
+- Copy the completed image to BFS in one sequential operation when practical.
+  This does not control eligibility, but avoids needless fragmentation of the
+  backing file. The default read-only mount is preferred when writes are not
+  required.
+
+The 64 KiB cluster improves eligibility but cannot force every access through
+the batch path: exFAT metadata and small or unaligned application I/O still use
+the safe fallback. In the ShadowMount debug log, an eligible profile request is
+shown by `img=5 sec=512 sec2=65536`; the kernel still makes the final BFS and
+platform checks internally.

 Windows:
 - Recommended: use `make_image.bat` (wrapper for `New-OsfExfatImage.ps1` + OSFMount).
@@ -273,13 +445,14 @@ Windows:
   - Install OSFMount: https://www.osforensics.com/tools/mount-disk-images.html.
   - Keep `make_image.bat` and `New-OsfExfatImage.ps1` in the same folder.
   - Run `cmd.exe` as Administrator.
-  - If you build an exFAT image manually instead of using the script, keep the cluster size at `64 KB` or you may lose performance.
+  - If you build an exFAT image manually, format it with a `64K` allocation unit, for example `format X: /FS:exFAT /A:64K /Q`.
 - Usage:
   - `make_image.bat "C:\images\game.exfat" "C:\payload\APPXXXX"`
 - Behavior:
   - Auto-sizes the image to fit source content.
   - Source folder must be the game root and contain `eboot.bin`.
   - Formats and copies source folder contents into image root.
+  - Uses a fixed 64 KiB allocation unit for both large-file and small/mixed-file images.
 - Optional (fixed size): run PowerShell script directly:
   - `powershell.exe -ExecutionPolicy Bypass -File .\New-OsfExfatImage.ps1 -ImagePath "C:\images\game.exfat" -SourceDir "C:\payload\APPXXXX" -Size 8G -ForceOverwrite`

+# ShadowMount HTTP/JSON API v1
+
+The machine-readable OpenAPI 3.1 description is available in
+[`openapi.yaml`](openapi.yaml).
+
+ShadowMount exposes its public API over HTTP/TCP. The default endpoint is
+`127.0.0.1:10101`, so only software running on the PS5 can connect. Set
+`api_bind_address=0.0.0.0` to allow clients on the network, or select a
+specific PS5 IPv4 address. `api_port` accepts values from 1 through 65535.
+Both settings are applied on runtime config reload.
+
+The API has no authentication. Bind it to a network-facing address only on a
+trusted network.
+
+The internal `/system_tmp/shadowmount.sock` Unix socket remains private to the
+SceShellCore bridge and must not be used by third-party applications.
+
+The HTTP service owns and monitors its listener. If initial `socket/bind/listen`
+or a later `accept` fails, it retries with an interruptible 250 ms to 5 s
+backoff. Only the transition into recovery and the successful recovery are
+logged. Shutdown and config reload interrupt the wait immediately.
+
+Every API operation must use `POST`, include `Content-Type: application/json`
+and contain one JSON object. Every response is a JSON object. Connections are
+closed after one response; chunked request bodies are not supported. The
+maximum request body is 4096 bytes.
+
+All responses include `Access-Control-Allow-Origin: *`. Browser preflight
+requests using `OPTIONS` are supported and allow `POST`, the `Content-Type`
+header and Private Network Access. This permits calls from any browser origin;
+the listener still needs `api_bind_address=0.0.0.0` for access from another
+device.
+
+## Routes
+
+| Route | Request | Purpose |
+| --- | --- | --- |
+| `/api/v1/version` | `{}` | API and ShadowMount versions plus capabilities |
+| `/api/v1/images` | `{}` | Complete image snapshot |
+| `/api/v1/games` | `{}` | Complete game snapshot |
+| `/api/v1/games/mount` | `{"title_id":"PPSA12345"}` | Mount a managed game |
+| `/api/v1/games/unmount` | `{"title_id":"PPSA12345"}` | Unmount a managed game |
+
+Example:
+
+```sh
+curl -sS http://127.0.0.1:10101/api/v1/version \
+  -H 'Content-Type: application/json' \
+  -d '{}'
+
+curl -sS http://127.0.0.1:10101/api/v1/games \
+  -H 'Content-Type: application/json' \
+  -d '{}'
+```
+
+## Responses
+
+Every response contains numeric `status`. It is zero on success, or a positive
+errno value on failure. Error responses also contain `error` and use an
+appropriate HTTP status such as 400, 404, 409, 413 or 415.
+
+A successful version response has this shape:
+
+```json
+{
+  "status": 0,
+  "api_version": 1,
+  "shadowmount_version": "1.7",
+  "capabilities": ["list_images", "list_games", "mount_game", "unmount_game"]
+}
+```
+
+List responses contain `count` and the complete `images` or `games` array.
+Image items expose `path`, `mount_point`, `size`, modification time, `unit_id`,
+`backend`, `complete`, `source_available`, `mapped` and `mounted`. Game items
+expose `path`, `image_path`, `title_id`, `title_name`, `installed`, `managed`,
+`mounted`, `image_backed` and `source_available`.
+
+Mount mutations remain conservative. They return HTTP 409 with `status` set to
+`EBUSY` while a game is active, while ShellCore owns another prepared title,
+during suspend, or while a conflicting mount/release is in progress. Clients
+must not retry this response in a tight loop. HTTP 404 with `ENOENT` means the
+title has no ShadowMount `mount.lnk` tracker.
+With `persistent_image_mounts=1`, unmounting a game releases its per-title
+runtime layers but keeps the backing image mounted.
+
+## Test client
+
+Run the host-side Python client while ShadowMount is active:
+
+```sh
+python3 tools/api_test.py 192.168.1.50 10101
+```
+
+It validates CORS preflight, the version response and complete image/game
+snapshots, then selects the first safe managed game for a mount/unmount cycle.
+The mutation test is skipped if there is no candidate or the runtime is busy.

+/*
+ * Mount profiles and cache layers
+ * ================================================================
+ *
+ * LVD geometry
+ * ------------
+ * sector_size is the logical sector exported by /dev/lvdN. It controls BIO
+ * alignment and is not a filesystem allocation block. ShadowMount defaults to
+ * 512 bytes for exFAT and 4096 bytes for UFS/PFS.
+ *
+ * secondary_unit is the LVD mapping/split granularity. ShadowMount uses 64 KiB
+ * for all supported image filesystems. It matches the exFAT/UFS allocation
+ * profile and PFS/PFSC block boundary, must be divisible by sector_size, and is
+ * required by the type-5 BFS sdimg path.
+ *
+ * LVD attach ABI and image types
+ * ------------------------------
+ * The kernel exposes base attach V0, extended attach V1/Attach2 and detach.
+ * ShadowMount builds one complete V0 layer and marks it NO_BITMAP. source_type
+ * 1 is a regular file; source_type 2 is a device/special source.
+ *
+ * Accepted image types and kernel names:
+ *   0 Dfl, 1 GmI, 2 GmO, 3 PtcI, 4 PtcO, 5 Sv, 6 Trp, 7 Dwl,
+ *   8 AcI, 9 AcO, 10 MaI, 11 MaO, 12 Pcdwl.
+ *
+ * Types 0/5/6/7/12 use lvdstart_vnode_direct. Types 1-4/8-11 use
+ * lvdstart_vnode and resolve each secondary unit through layered bitmap and
+ * optional OTBL metadata. Current ShadowMount profiles are:
+ *
+ *   .exfat                         type 5  Sv,  direct + BFS sdimg batching
+ *                                  fallback: type 0 Dfl
+ *   .ffpkg (UFS)                  type 5  Sv,  direct + BFS sdimg batching
+ *   standalone .ffpfs             type 5  Sv,  direct
+ *   outer .ffpfsc                 type 9  AcO, layered package outer
+ *   inner .ffpfs/pfs_image.dat    type 8  AcI, layered package inner
+ *
+ * ShadowMount deliberately uses type 5 with single/save attach flags for UFS
+ * images so a standalone .ffpkg on BFS can use sdimg batching. Type 7 with
+ * Download Data instead favors HDD request isolation. UFS nmount has
+ * no separate download-data flag: 0x10000000 is the generic MNT_NOATIME bit,
+ * not an UFS or DD mode. Do not substitute GmO/PtcO only to request the UFS
+ * block-map cache: that replaces direct dispatch with layered dispatch. The
+ * kernel requests that cache only for type 2/4, an HDD-class regular backing
+ * vnode, and a backing filesystem that is UFS.
+ *
+ * Type-5 BFS sdimg fast path
+ * -------------------------
+ * Type 5 labels the LVD provider "Ssd" and may enable BFS sdimg when the image
+ * is a regular file on internal BFS and secondary_unit is exactly 64 KiB. The
+ * kernel also applies platform/storage-mode and lower-provider guards.
+ *
+ * When enabled, lvd_worker accepts only requests whose length is exactly
+ * 64 KiB and whose backing-file offset is 64-KiB aligned. It collects the
+ * initial request plus up to 30 matching queued requests and submits them via
+ * bfs_iosession_rw_sdimg/BfsSdimg. All other requests fall back to the normal
+ * vnode path. This is block-I/O batching, not an exFAT cache or decompressor.
+ *
+ * For exFAT keep sector_size at 512 and create the filesystem with a 64-KiB
+ * allocation unit. Setting sector_size to 65536 does not request this mode;
+ * the relevant LVD value is secondary_unit. The path is unavailable through
+ * MD or when the image is backed by USB/UFS/PFS/exFAT instead of BFS.
+ *
+ * Raw flags and validator
+ * -----------------------
+ * Download-data flags exist only in the LVD attach ABI. ShadowMount calls
+ * /dev/lvdctl directly and normalizes wrapper-style presets:
+ * raw 0x8/0x9 -> single/save-data family 0x14/0x1c;
+ * raw 0xc/0xd -> download-data family 0x16/0x1e.
+ * Firmware pairs raw bit 0 with read-only variants; it is not an independent
+ * LVD read-only flag. The normalized validator masks are:
+ *
+ *   type 0,5,6,8-11: (flags & 0x92) == 0x10
+ *   type 1:           (flags & 0x82) == 0x80
+ *   type 2,3,4:       (flags & 0x82) == 0
+ *   type 7,12:        (flags & 0x92) == 0x12
+ *
+ * Download Data HDD worker policy
+ * -------------------------------
+ * Download Data is normalized LVD bit 0x02 and is required by types 7 and 12.
+ * On an HDD-class provider it makes LVD create two request workers instead of
+ * one: worker 0 is labelled System (lvdhdsw), worker 1 Game (lvdhdgw). The LVD
+ * start routine routes each BIO using the kernel classification byte at
+ * BIO + 0x172: value 1 selects Game and every other value selects System. LVD
+ * also tracks and drains the workers separately during shutdown. The flag is
+ * therefore an HDD queue-isolation/QoS policy, not an on-disk-format property.
+ *
+ * Download Data does not select direct BIO dispatch (image_type does), enable
+ * bitmap/OTBL interpretation, populate the UFS block-map cache (types 2/4),
+ * unlock BFS sdimg batching (type 5), or enable PFS/compression caches. For a
+ * standalone image, type 7 + Download Data is the HDD-oriented choice when
+ * System/Game queue separation matters. Type 5 + Single/Save is preferable for
+ * a BFS sdimg-backed .ffpkg when maximum sequential/batched throughput matters
+ * and the two-queue HDD policy is not needed.
+ *
+ * Layer metadata and independent caches
+ * -------------------------------------
+ * LVD bitmap says whether a logical unit is present in a layer. V1 OTBL maps a
+ * logical unit to a physical unit inside the layer file. It is unrelated to a
+ * PFSC compressed-offset table.
+ *
+ *   LVD bitmap/OTBL       image-layer presence/remapping
+ *   UFS block-map cache   backing UFS file blocks -> physical UFS blocks
+ *   PFS GDDR5 ioctl       PFSC compressed offsets and optional full ICV
+ *
+ * The UFS cache depends on the filesystem containing the image, not UFS stored
+ * inside .ffpkg, and is unavailable for BFS/PFS/exFAT backing files. The PFS
+ * metadata ioctl applies to every nested image backed by pfs, ppr_pfs,
+ * transaction_pfs, or a forwarding overlay; the filesystem inside the image
+ * does not need to be PFS.
+ *
+ * PFS/PPR compression dispatch
+ * ----------------------------
+ * Classic pfs and ppr_pfs are distinct kernel read paths. A classic compressed
+ * PFS block uses the classic PFSC header/table interpretation and the pfs path
+ * dispatches its compressed payload to zlib. The PPR variant interprets the
+ * PPR block metadata and can dispatch Kraken. LVD image_type, the nested
+ * selector and PFS_GDDR5_CACHE_IOCTL do not select a decompressor and cannot
+ * turn a classic zlib block header into a PPR/Kraken block. The image creator
+ * must emit the matching on-disk block records and offset table.
+ *
+ * Compression is decided per block. Files excluded from compression and blocks
+ * that are not smaller after compression are stored as raw blocks but remain
+ * represented in the same image offset mapping. This is independent of the
+ * mount-time caches described below.
+ *
+ * PFS compression caches and big-app reserve
+ * ------------------------------------------
+ * Three independent mechanisms have similar historical GDDR5/SBRAM cache
+ * names and must not be treated as one allocation:
+ *
+ *  1. A compressed PFS/PFSC mount can allocate its own cmp_offtbl cache. The
+ *     kernel message
+ *
+ *       pfs_allocate_cmp_offtbl_cache(): cmp_offtbl is cached
+ *
+ *     confirms this mount-local compressed-block offset table. It is created
+ *     by the PFS mount path and is not evidence that a big-app memory reserve
+ *     exists.
+ *
+ *  2. PFS_GDDR5_CACHE_IOCTL is issued on a nested image's backing vnode before
+ *     LVD attach. It requests the containing PFS/PPR read path to cache the
+ *     compressed-offset table used to reach that vnode's data; it does not
+ *     inspect or impose a format on the bytes stored inside the file. Thus the
+ *     nested file may contain PFS, UFS, exFAT or arbitrary block data and need
+ *     not itself be compressed. The hard requirement for the offset request is
+ *     that the containing PFS/PPR image has its compressed-image flag set. On
+ *     an uncompressed containing image the kernel logs "NOT a compressed
+ *     image" and accepts the request as a compatibility no-op.
+ *
+ *     cmp_cache_units is a count of shared-cache allocation units, not bytes.
+ *     The compressed-offset pool uses 0x10000-byte units and has 600 units
+ *     (37.5 MiB) with at most eight simultaneous slots. A zero count makes the
+ *     kernel derive the required count from the on-disk offset-table geometry;
+ *     this is the preferred full-table/default request. An explicit nonzero
+ *     count limits the reservation and can force more LRU refills. EBUSY is
+ *     non-fatal: it means that this vnode already has a cache or that all eight
+ *     slots are occupied. ENOMEM means that the requested units exceed the
+ *     remaining total or contiguous shared-cache space.
+ *
+ *     The optional full-ICV request is independent. It requires the containing
+ *     image's signed-image flag and usable ICV metadata; otherwise the kernel
+ *     rejects that half of the request. It also has its own eight-slot pool.
+ *     Neither half selects zlib/Kraken or changes the block-record format.
+ *
+ *  3. The 180-MiB big-app reserve is application-lifecycle memory. It is not
+ *     allocated by the ioctl, LVD, PFS nmount, EnsureBigAppBudget, or a visible
+ *     /dev/sbram device. During BEGIN_APP_MOUNT_EVENT the kernel allocates
+ *     0x0B400000 bytes aligned to 0x200000 for selected category values:
+ *
+ *       0x0000F000, 0x0000F100, 0x0001F000, 0x0001F300,
+ *       0x0002F000, 0x0200F100.
+ *
+ *     The allocation belongs to the big-app/application context. PFS can bind
+ *     to it through the application lifecycle callbacks; userland is not given
+ *     a buffer pointer. EndAppMount tears the context down and releases the
+ *     reserve after the application pre-delete path. Consequently a managed
+ *     image stack must remain mounted until the matching EndAppMount hook, and
+ *     no explicit metadata-cache clear should run while its PFS vnode is live.
+ *
+ * For unsigned ShadowMount PFS profiles sigverify=0, so request only compressed
+ * offsets (cache_full_icv=0). Signing does not make ordinary reads faster: it
+ * enables integrity verification and can add work; a cached full ICV table
+ * only reduces metadata lookup cost when verification is actually enabled.
+ * Both compressed-offset caches are properties of the outer PFS read path.
+ * They can accelerate an LVD-backed nested exFAT/UFS/PFS image because the
+ * inner filesystem format is irrelevant at that layer.
+ *
+ * Backend and nmount policy
+ * -------------------------
+ * LVD is the default for every format. MD is a compatibility backend for
+ * UFS/exFAT; it uses AUTOUNIT|ASYNC and native logical sectors (UFS 4096,
+ * exFAT 512). Read-only state is applied to the backing
+ * device and nmount. Current nmount profiles are:
+ *
+ *   UFS   ufs + budgetid + async + noatime + automounted
+ *   exFAT exfatfs + large + static-timezone + async + noatime + ignoreacl
+ *   PFS   pfs + AC + game + sigverify/playgo/disc=0 + zero ekpfs
