Read + AES-decrypt + zlib-inflate the payload cache. Returns (payload, iv).

Resolve an ordered group of patches; later patches may reference earlier resolved offsets via relative_to_patch_index. Returns None if any required pa

Append a literal suffix (e.g. ".tmp", ".orig", ".bak") to a path's full name. Matches the C# `path + ".tmp"` behavior (not OS extension replacement).

Per-feature flag AND'd with the ST-gate (for hook-based paths only).

<summary> Shows a choice dialog with a primary action and a secondary/close action. Returns true if the user chose the primary button. </summary>

Clamp file sizes at the wire boundary; Steam's protobuf fields are uint32.

Legacy CAS path: "{account}/{app}/blobs/{sha1hex}" (migration read-only)

<summary> Shows a danger confirmation dialog with a countdown timer. The "Yes" button is disabled and shows a countdown (e.g. "Yes (3)") until the tim

Shared Cloud RPC dispatch - routes a method name to the appropriate handler. Returns std::nullopt if the method is not a recognized Cloud RPC we handl

Drain on net thread.

Accrue + persist the in-flight session for `appId`, erasing it from g_activeSessions. Caller holds g_mutex. Returns false if no session was open. Shar

Lazy load; ++ on a missing key would silently regress to 1.

Serve-path accessor: reuse a recent snapshot when provably safe, else live.

allowLegacyMigration=false reads canonical state without migration side effects; used by PublishCloudState's CN-regression re-check to avoid recursive

Convert a filesystem mtime to whole Unix seconds, rounded to nearest. Flooring recorded a time_stamp one second below the mtime Steam reads off the sa

Scan readable ranges within steamclient for a byte sequence.

Search steamclient ranges for a pointer value; tries `primary` first, falls back to `fallback` to avoid false positives on small values.

<summary> Returns the path to the manifest pin config in the Steam folder (per-system, not per-user). Returns null if Steam isn't found. </summary>

<summary> Returns the display name of the configured cloud provider, or null if local-only. </summary>

BeginAppUploadBatch

ClientBeginFileUpload Tell Steam to PUT the file to our local HTTP server.

ClientCommitFileUpload The file has been PUT to our HTTP server. Update local metadata.

CompleteAppUploadBatchBlocking

ClientDeleteFile

ClientFileDownload Tell Steam to GET the file from our local HTTP server.

Returns the blob-store file list; Steam compares vs. remotecache.vdf.

SignalAppLaunchIntent: return pending_remote_operations. Also pre-restores cloud files to game folders so Steam's sync finds them on disk.

ClientGetAppQuotaUsage

Install the vtable hook on CClientUnifiedServiceTransport

Invalidate the blob index for an app (called after uploads/promotions change the layout).

<summary> Returns true if the embedded DLL resource exists in this assembly. </summary>

<summary> Checks whether the deployed DLL matches the embedded version. Returns null if the file doesn't exist, true if up to date, false if outdated.

Self-unlocking lua: contains addappid(<own appId>), i.e. base game is lua-unlocked. DLC-only luas don't and are excluded.

<summary>Accepts a Steam CDN URL or a file:// URI under the local image cache.</summary>

Only allow plain "name.lua" filenames (no paths, no ..)

Bounded join used at shutdown so a wedged worker can't keep Steam alive. Timeout detaches; the OS reaps at process exit.

<summary> List only cleanup tab backups. </summary>

Prologue check + boundary validation (CC/C3 padding or 16-byte aligned).

See g_ownClientId.

Reject invalid sibling tokens.

Returns: 1 patched, 0 skipped (not found), -1 failed.
