* Active (running) turn for the (agentId, sessionId) pair, if any. * Used by route layer for collision detection on POST /chat.

Validate checks preconditions; an error stops the pipeline before Execute (fail fast).

The action layer (click/fill/type/...) for a page, sharing its observation refs.

Reacquires the page session once after transient CDP reconnect errors.

AppPath resolves the built app path (context.py get_app_path): FixedAppPath wins; macOS debug builds prefer "<base> Dev.app" when present.

Opens the shared DOM fixture after its static form controls are queryable.

* Push an event into the turn's buffer and fan out to live * subscribers. Terminal events transition status and start the * retention window.

Copy performs a server-side object copy within the bucket.

devContext builds the Context shared by every dev leaf; --chromium-src is required (cli/dev.py callback).

Written returns every path the plan actually rewrites.

* Build text-heavy user/assistant exchanges WITHOUT tool calls. * These survive pruning and output reduction, forcing LLM summarization * when large

fixtureCtx builds a Context over a fake package root + chromium src with a recording runner.

ResolveContexts returns one Context per architecture (resolver.py resolve_config). CONFIG mode when yamlCfg is non-nil.

commandProgress routes long-running engine updates to stderr in human mode only.
