What it does
Where you use it
The pinned release supplies native desktop and phone clients plus a headless engine; it does not supply a released interactive browser ADE client. Public member cards are read-only presentation pages.
Source and scope for Where you use itAgents it runs
Zeron runs the documented built-in harnesses plus registry-provided ACP agents. Gemini CLI is available through its dynamic ACP registry installation/launch path; the existing named harnesses retain their cited release scope.
Source and scope for Agents it runsAccounts and subscriptions
Cloud credentials support native Claude OAuth/setup-token and ChatGPT/Codex OAuth, with scope limited to the designated native harness. Optional Cloud also accepts supported provider API keys. Account slots, plan/usage probes and login flows are part of the documented native account system. Default local use needs no Zeron account or network connection; optional sync requires sign-in.
Source and scope for Accounts and subscriptionsWhere agents run
Local execution remains the default owned-device mode. Linux headless mode runs on an always-on server/VPS independently of the controlling laptop. Opt-in Cloud gives each session a hosted Boat machine; v1 agents are Claude Code/Codex. Headless VPS execution continues after the laptop closes; detached desktop engine survives quitting its UI while its host stays awake.
Source and scope for Where agents runHow work is kept apart
Engine manages Git worktrees as separate checkouts. Each Cloud session receives its own sandbox machine and repository clone, while its side chats can share that machine and files. The checked Zeron source does not name a VM isolation technology.
Source and scope for How work is kept apartParallel work
MCP create_chats supports multiple children and Cloud can provision per-session machines.
Source and scope for Parallel workScheduled runs
Allowed plugin services can run configured agent programs periodically with engine-owned timers; this is an extension API, not a built-in scheduling screen.
Source and scope for Scheduled runsGit and pull requests
Worktree RPCs and project actions manage separate checkouts. Cloud GitHub App credentials allow pushes and gh pr create as the App, not the personal GitHub identity.
Source and scope for Git and pull requestsPrice
The local application is MIT licensed and free to use. Hosted Cloud tracks machine-minute credits and operator billing reports; a current public USD rate, purchase flow and complete paid-plan table are unestablished. Agent/model charges remain separate.

Unattended triggers
Typed value: Yes.
Allowed plugin services can run configured agent programs periodically with engine-owned timers; this is an extension API, not a built-in scheduling screen.
- Schedules: zeron.every invokes callbacks at intervals of at least 30 seconds; commands-granted plugins can launch a permitted agent program.
- Scheduler location: Plugin timers run in the engine service on the selected host.
- Client independence: The headless engine starts a stopped plugin service when a timer becomes due; the host must stay running.

-
Zeron: crates/engine/src/plugins/service/prelude.luau
Finding: A user-installed, allowed plugin service can register zeron.every callbacks (minimum 30 seconds). The engine fires callbacks headlessly and restarts stopped services for due timers. With the commands grant, zeron.run executes permitted programs, so a plugin can periodically launch a configured agent command without a per-run prompt. The engine host must remain running.
Shared prompting: No
Shared prompting
Typed value: No.
Organization metadata can be shared, but the scoped sync service restricts each chat document to its owning account. Two distinct human accounts cannot co-prompt that same chat through this interface.

Zeron: crates/doc/src/schema.rs
Finding: The release has native desktop/mobile clients and engine/RPC services, with no released interactive ADE web or phone-browser client. Persistence uses projects, chats, messages and agent todo tool parts rather than an independent issue entity. Chat-room ownership rejects another user, while organization workspace metadata is shared. Members UI and auth routes implement admin/member roles: admins manage names, roles, people and invitations; members view membership. No enterprise SSO configuration UI was found; WorkOS-hosted configuration remains outside this inspection.

Telemetry opt-out: No
Telemetry opt-out
Typed value: No.
Native apps have no analytics/crash SDKs, and the pinned app settings/engine exposes no app telemetry opt-out control. Website PostHog honors browser GPC/DNT separately; optional hosted sync and Cloud processing retain their own documented data policies.
- Code data: Optional sync stores transcripts/tool output/diffs on hosted servers; they are not end-to-end encrypted. Local profiles are separated.
- Deletion: Policy allows deleting chats/projects and requesting account deletion, with stated 30-day live-service/backups removal and billing-record exceptions.
- Telemetry disclosure: Privacy policy says apps have no analytics/crash SDKs; homepage PostHog is separate.
- Telemetry controls: No app telemetry opt-out control in the scoped native app; website GPC/DNT only controls website analytics.
- The app control finding does not assert an opt-out from hosted-service operational logs, model-provider processing or website analytics.
-
Finding: The policy separates local app data from optional synced transcripts and Cloud credentials. Apps have no analytics/crash SDKs; website PostHog honors browser GPC/DNT. Synced chats are encrypted at rest/in transit, not end-to-end.
-
Zeron app settings and telemetry boundary
Finding: The scoped app settings/engine inspection exposes no app analytics/crash telemetry toggle. The first-party privacy policy states the native apps have no analytics or crash SDKs, while the website honors GPC/DNT for its own PostHog. A website analytics control is not an ADE-wide app opt-out.

Zeron dynamic ACP agent registry
Finding: The public product implementation installs and launches any entry in the official ACP registry through the generic ACP harness, including npm distributions. Its explicit Gemini CLI fixture names @google/gemini-cli --acp, and the referenced live official registry retrieved in this pass includes Gemini CLI. This is a coding-agent integration, not the Google model-provider name.
-
Official ACP agent registry: Gemini CLI
Finding: The official registry fetched in this pass lists Gemini CLI 0.68.0 with pinned npm distribution @google/gemini-cli@0.68.0 and --acp launch arguments. Zeron pinned source implements installation/launch of this registry distribution type.

Local execution remains the default owned-device mode. Linux headless mode runs on an always-on server/VPS independently of the controlling laptop. Opt-in Cloud gives each session a hosted Boat machine; v1 agents are Claude Code/Codex. Headless VPS execution continues after the laptop closes; detached desktop engine survives quitting its UI while its host stays awake.
- Only the cited atomic findings are established. Remaining atomic requirements and the full rubric scenario remain unverified.
-
Finding: Local use needs no Zeron account; Linux headless service keeps agents on a VPS after laptop closure. Optional same-account sync allows peers to read/write each others workspace files; existing local sessions are not uploaded.
-
Finding: Rust engine and GPUI desktop use the same RPC. Detached engine can survive client quit; local and synced stores are separate. Supported self-hosted sync-backend contract is explicitly deferred, distinct from owned-device execution.
-
Zeron docs/design/cloud-device.md
Finding: Opt-in Cloud starts per-session Boat machines for Claude Code or Codex with separate provider connections. API keys or supported native OAuth accounts are brokered; side chats can share the parent sandbox.
comet:RUN-02: Engine manages Git worktrees as separate checkouts. Each Cloud session receives its own sandbox machine and repository clone, while its side chats can share that machine and files. The checked Zeron source does not name a VM isolation technology. cross-checked

Background tray reads bounded live command output and waits for runtime confirmation before removing stopped entries. Shared projection distinguishes working, awaitingInput, errored, completed and idle and exposes stale evidence separately.
- Only the cited atomic findings are established. Remaining atomic requirements and the full rubric scenario remain unverified.
-
Finding: Desktop/mobile/MCP derive working, needs-input, error, completed and idle states from native/terminal evidence. Expired liveness is stale, not successful completion.
-
Zeron docs/background-processes.md
Finding: Desktop lists/reads/stops background Claude/Codex commands with runtime-confirmed completion; other harness and mobile tray coverage is explicitly absent.

Zeron: crates/doc/src/schema.rs
Finding: The release has native desktop/mobile clients and engine/RPC services, with no released interactive ADE web or phone-browser client. Persistence uses projects, chats, messages and agent todo tool parts rather than an independent issue entity. Chat-room ownership rejects another user, while organization workspace metadata is shared. Members UI and auth routes implement admin/member roles: admins manage names, roles, people and invitations; members view membership. No enterprise SSO configuration UI was found; WorkOS-hosted configuration remains outside this inspection.
comet:TEAM-02: Organization membership has named admin and member roles in the native Members screen and server permission checks. Enterprise SSO availability is not established by the generic WorkOS token verifier.

Finding: The policy separates local app data from optional synced transcripts and Cloud credentials. Apps have no analytics/crash SDKs; website PostHog honors browser GPC/DNT. Synced chats are encrypted at rest/in transit, not end-to-end.
-
Zeron app settings and telemetry boundary
Finding: The scoped app settings/engine inspection exposes no app analytics/crash telemetry toggle. The first-party privacy policy states the native apps have no analytics or crash SDKs, while the website honors GPC/DNT for its own PostHog. A website analytics control is not an ADE-wide app opt-out.
