CaptureTool (built next to the servers) replays packet bundles and compares the answers: - replay: per bundle a fresh sandbox folder with copied server binaries, rewritten settings (replay_sandbox=1, a new SQLite file inside the folder, ports from --port on, no dashboard), read back before anything starts; sandbox-setup runs inside it to apply migrations and make the replay account and the bundle's characters (setup mode); master is started, the stack is stopped as one process group and the folder deleted unless kept - with replay_sandbox=1 every server refuses a database that isn't SQLite, isn't inside its own folder, or is replay_live_sqlite_path (Database::Connect); replay-target against a running server needs --i-know-this-is-not-a-sandbox - the fake client splits the recording into connections, logs in and picks the character itself when the recording doesn't, fills in the target's account, session key and IDs, learns server-made object IDs from replica constructions by LOT, follows the recorded timing and waits for the answers a client waits for; the diff pairs answers by name (and constructions by LOT) and ignores fields that differ between runs - import-live converts the 2014 live captures (folders of *_traffic.zip; pcaps and encrypted captures are left alone) into bundles, with secrets removed and CREATE_CHARACTER as setup - anonymise makes local fixtures; docs/CaptureReplay.md describes capture, the bundle format, portability rules, the sandbox and the replay Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

/**
|
|
* Replays a bundle's client packets against a server with the fake client (docs/CaptureReplay.md) and compares the
|
|
* server's answers with the recorded ones.
|
|
*
|
|
* The recording is split into connections (each starts with the client's VERSION_CONFIRM). The replay logs in on
|
|
* the target's auth server itself when the recording has no login, and goes through character select itself when
|
|
* the recording starts in a zone. Before a packet goes out, what must differ on the target is filled in: the
|
|
* target account's name and password, the session key the target's auth gave, and the target's IDs for the
|
|
* characters (the bundle's placeholders). Timing follows the recording (sped up, and never more than a few seconds
|
|
* between packets), and the replay waits for the answers a real client waits for (the handshake, the character
|
|
* list, the zone to load, the world to transfer to).
