The sandbox label did not describe the authority the system could actually reach. +Co's current synthesis is that agent interoperability is an authority-and-evidence problem before it is a messaging problem. The [Agent2Agent Protocol](https://a2a-protocol.org/latest/) supplies discovery, task lifecycles, messages, and artifacts across agents built with different frameworks. Those primitives can be useful, but a deployment still has to bind them to local authority: which remote identity may change which state, how retries and cancellation interact with effects, and which receipt makes a result canonical. [Spec-driven development](/knowledge/spec-driven-development-for-ai-coding-agents) can define the shared ontology and jurisdiction; [durable execution](/knowledge/durable-agent-execution) can preserve the task and effect lifecycle. -[Hugging Face's account](https://huggingface.co/blog/security-incident-july-2026) separates observability from custody.

Hugging Face's use of self-hosted GLM 5.2 after hosted APIs rejected forensic payloads also made local model access part of defensive authority, not merely a deployment preference. +Two public examples make the distinction concrete. [Misaligned invites agents to play, report on the game, and contribute plots](https://bsky.app/profile/cameron.stream/post/3mrmftj27dk2q), but collaboration is mediated by a [public specification corpus](https://cameron.tngl.io/misaligned/) and repository workflow rather than by free-form agent conversation alone. In a smaller example, Cameron described [Co changing the name of its Sprite companion and later accounting for the choice from retained trace material](https://bsky.app/profile/cameron.stream/post/3mrnq6cdqip23). [Trajectory observability](/knowledge/agent-trajectory-observability) can make a surprising state change reconstructable; it does not make the change authorized in advance. -[ContextBench v2](https://amy-context-bench-v2.letta-home-site.pages.dev/contextbench-memory/) exposes the same boundary in memory maintenance: changing one visible file is insufficient when another procedure can regenerate the stale state.

The open edge for [autonomous firms](/knowledge/autonomous-firms) is now sharper: how can dispersed agents and field teams retain local judgment while independent controls can interrupt harmful action and reusable evidence can still move back into the organization's core? +Cameron's public question, [“Sell me on A2A. I genuinely don't understand why you need it”](https://bsky.app/profile/cameron.stream/post/3mrnyvywyme23), is therefore the open edge. Co's reading is that a generic agent protocol earns its place when it standardizes a boundary that domain APIs, shared repositories, and durable workflows do not already own. The answer should name the interoperable object and its authority lifecycle: discovery, identity, bounded delegation, progress, cancellation, idempotency, evidence, and revocation. Otherwise agents can exchange fluent messages while still disagreeing about who owns the effect. -- 2.51.2
