V124.1 source-carried capabilities

Solved outcome

What this enables

Carry and globally synchronize complete application and file truth without a database or external proof authority; begin large mobile video from verified ranges; automate every SDK, MCP, and AI Skill capability without creating another authority.

Permanent anchor · #v124-1-source-carried-capability-discovery

Capability discovery

Import RECEIZ_V124_1_CAPABILITY_INVENTORY from @receiz/sdk. Each of its six rows binds one implemented primitive to exact SDK exports or client methods, MCP tools, AI Skills, an outcome, and an authority boundary. Automation must stop rather than invent a missing binding.

Permanent anchor · #v124-1-source-carried-any-sealed-file

Any sealed file

Inline RMA2 and complete RMC1/RMC2 source families reconstruct exact sealed bytes without a database, CDN, third-party media host, or external proof authority. Browser-supported video, audio, image, EPUB, PDF, and text render directly; every other binary remains exact and exportable.

Permanent anchor · #v124-1-source-carried-progressive-mobile-playback

Progressive mobile playback

A complete progressive ledger root is sealed inside the enclosing Signature-V4 proof. The browser verifies and plays the first required range while later ranges settle behind playback. Byte windows scale from bitrate and container needs; legacy whole-SHA artifacts retain whole-artifact admission.

Permanent anchor · #v124-1-source-carried-global-source-carried-state

Global source-carried state

Exact sealed replay sources open, diff, merge, and project every valid sibling branch. Public material packages finalize before their coordinates are advertised. Transport adds availability only and never becomes proof authority.

Permanent anchor · #v124-1-source-carried-conversation-and-cognition

Conversation and cognition

Receiz-ID participant bindings, complete causal history, bounded epoch-grant operations, and epoch rotation support direct or unlimited invited-member communication. Clear messages, epoch secrets, private imported memory, and private identity state remain outside model output. Twin responses cite proof and remain non-authoritative proposals.

Permanent anchor · #v124-1-source-carried-portable-account-continuity

Portable account continuity

Identity Seal, Identity Record, and Receiz Key carry profile, showcase, wallet, market positions/history, media, preferences, and proof history. Verified carried state paints immediately; synchronization may append verified additions behind it but cannot replace it.

Permanent anchor · #v124-1-source-carried-automation-contract

Automation contract

The MCP registry contains 169 tools, including 26 V124 production-runtime tools. skills.json carries the same six-family inventory; every relevant AI manifest carries exact v124_1CapabilityIds; and the packed-package parity gate proves every named export, client method, MCP tool, and skill binding.

Copyable path

Authenticated SDK issuance → Verify → inspect receipt

import { createReceizClient } from "@receiz/sdk";

// Begin with the complete proof object already held by the person or runtime.
const encoded = process.env.RECEIZ_ARTIFACT_BASE64;
if (!encoded) throw new Error("RECEIZ_ARTIFACT_BASE64 is required");
const artifactBytes = Uint8Array.from(Buffer.from(encoded, "base64"));

// Local verification is account-free and precedes every transport projection.
const receiz = createReceizClient();
const verification = await receiz.verification.verifyArtifact(artifactBytes);
if (verification.status !== "verified-artifact") {
  throw new Error(`Artifact verification status: ${verification.status}`);
}
console.log(verification.status);
