Every turn runs on the AI owner now, so the ledger's per-host column had collapsed to a single name and the fleet breakdown said nothing. The asking node travels with the request and is validated before it is written, which also retires ai_token_sync.sh — a partner ledger is empty by construction.

// ═══════════════════════════════════════════════════════════════════════════════════════════════
|
|
// PURPOSE
|
|
// Every AI action, in one dispatcher, independent of how the request arrived. api/ai.php calls
|
|
// it for browser requests; Tools/ai_rpc.php calls it for mesh requests forwarded from another
|
|
// node over SSH. Both get identical behaviour because there is only one implementation.
|
|
//
|
|
// DESIGN PRINCIPLES
|
|
// Transport-free. Nothing here reads a superglobal, sets a header, echoes, or exits. Handlers
|
|
// take a params array and return the response body as an array. That is what makes the
|
|
// same code serveable over HTTP and over SSH — the handlers cannot tell the difference,
|
|
// so the two paths cannot drift.
|
|
//
|
|
// The dispatcher owns behaviour; the caller owns access.
|
|
// Authentication, CSRF and the node/action gates live in the caller. This file assumes
|
|
// the request is already allowed. Two callers with different trust models share one set
|
|
// of handlers precisely because the handlers do not re-litigate trust.
|
|
//
|
|
// Extracted, not rewritten.
|
|
// This was the body of api/ai.php. The transformation is mechanical — `echo json_encode(X);
|
|
// exit` became `return X`, a 405 became $httpStatus plus a return, and superglobals became
|
|
// $p. Every validation, every whitelist and every comment is the original. A refactor of a
|
|
// file this security-sensitive earns nothing by also being a redesign.
|
|
//
|
|
// OPERATIONAL SAFEGUARDS
|
|
// Tokens are minted here and never accepted from elsewhere.
|
|
// random_bytes, hex, fixed length. A job's answer is readable by anyone who can guess its
|
|
// token, so the token is not guessable.
|
|
//
|
|
// Every token is validated as hex before it composes a path.
|
|
// vv_ai_job_path() returns null for anything else, and each caller checks. That pattern is
|
|
// what confines reads and deletes to the job directory.
|
|
//
|
|
// History is validated per message, not trusted as a blob.
|
|
// Role must be user or assistant, content must be a non-empty string, and each is
|
|
// truncated. A crafted history could otherwise inject a system role or push the context
|
|
// past the offload ceiling. chat_save applies the same validation, because a stored chat
|
|
// is replayed into a later prompt.
|
|
//
|
|
// Scope is whitelisted, not escaped.
|
|
// It reaches the model as text, so anything richer than a file name is an
|
|
// instruction-injection surface for no benefit.
|
|
//
|
|
// stop signals one verified pid, never a process group.
|
|
// The cmdline must name both the worker and this job's own token before anything is
|
|
// signalled, because pid reuse is real. Group signalling took the WebGUI down on
|
|
// 2026-08-07.
