Several follow-ups queued before a coding run retain all their instructions and source-message identities, rather than replacing one another. +The optional `codex_transport: "app-server"` replaces the coding task's `exec` +child with one controller-owned stdio app-server under the same inherited lock. +The default remains `exec`. The owner records the exact task/attempt/thread/turn +in `active_turn`, preserves the configured model, effort and permission profile, +and checks for explicitly bound steering during existing activity checkpoints. +Queue messages stay with ordinary inbox processing. Steering is reserved before +dispatch; an acknowledgement is recorded as accepted, never as model consumption. +Lost acknowledgements remain uncertain and are not retried or converted to Queue. + +The existing owner publishes a short-lived operational observation of that exact +binding and its task delegator. The message API resolves it only for the +authenticated delegator in the shared organisation and rechecks the canonical +assignment and current execution attempt before accepting Steer. A browser cannot +publish a target. The owner refreshes its observation at existing checkpoints; +withdrawal removes only its own binding. An unavailable owner leaves the draft +intact and offers Queue explicitly. + +Admission stores the intended binding with the original message. Retries retain +that binding and delivery key, including an ambiguous HTTP result. The owner +records accepted, not-applied or uncertain receipts on the canonical message; +retained receipt recovery never replays guidance. The message pane distinguishes +stored/pending guidance from controller acceptance and does not claim model +consumption from an acknowledgement. + +Production activation and real consumption evidence are separate from these +code paths. The default `exec` owner and the current Mac stdio-only owner publish +no target, so those routes continue to offer Queue. A Mac owner adapter/runtime +choice remains outstanding in [PR #692](https://github.com/Strong-AI-Lab/Von/pull/692). +Local protocol and browser fixtures do not establish provider identity, +production activation or live consumption. + The reply prompt permits relevant read-only host/repository inspection.
