Build durable streams for real-time data subscriptions. iii-stream is deprecated (iii-stream) and will be removed in an upcoming release. Behavior is unchanged for now. Migration guide: https://iii.dev/docs/upgrading/migrate-from-streams
iii trigger compose::add worker=iii-streamSpawn ephemeral microVMs and expose 14 sandbox::* triggers (lifecycle + filesystem) for isolated command execution and file ops.
iii trigger compose::add worker=iii-sandboxDistributed key-value state management with reactive change triggers — registers the `state` trigger type, the observable `state::on-changed` function (iii 0.25) and the `state::*` functions.
iii trigger compose::add worker=stateExpose functions as HTTP endpoints — registers the `http` trigger type and the observable `http::on-request` function, and serves matched routes.
iii trigger compose::add worker=httpDurable function queues - registers the `durable:subscriber` trigger type, the `queue::on-message` observable function and the queue/DLQ service functions.
iii trigger compose::add worker=queueSchedule functions with cron expressions - registers the `cron` trigger type and the observable function `cron::on-tick` (iii 0.25).
iii trigger compose::add worker=cronOpenTelemetry-based traces, metrics, logs, alerts, and sampling.
iii trigger compose::add worker=iii-observabilityOne front door + provider protocol in front of every LLM provider.
iii trigger compose::add worker=llm-routerEngine introspection, workers registry proxy, filesystem-backed skills, system prompts, and agent profiles, kit install and update with reviewed plans, plus function search ranked by the judge worker (falling back to local hybrid/lexical) with a conditional pre-generate hint.
iii trigger compose::add worker=iii-directoryTalk to PostgreSQL, MySQL, and SQLite from iii — query, execute, transactions, prepared statements, and change feeds.

Checkout failed because the payment retry was never awaited. I reproduced it in a sandbox, patched it, and opened PR #512. The tests pass.
Sample session: the prompt “Checkout is failing on staging. Find out why and open a fix.” runs directory::search_functions, which finds five functions in 3 milliseconds. The harness then calls browser::navigate, sandbox::exec, router::chat, state::set and github::pr::create through iii, and replies: Checkout failed because the payment retry was never awaited. I reproduced it in a sandbox, patched it, and opened PR #512. The tests pass.
