Interactive TTY sessions now use dialoguer widgets (Select, MultiSelect,
Confirm, Input) instead of raw eprintln/read_line. Non-TTY input falls
back to the existing line-based reader. Suppresses redundant "Stage
started" inform message for wait.human nodes since the prompt itself
serves as notification.

- Drop event_tx from ManagedPipeline when pipeline completes/cancels/fails so
SSE streams end promptly instead of blocking until timeout (3.5s → 0.02s)
- Switch reqwest from native-tls to rustls-tls to avoid 500ms macOS cert store
load per process (0.67s → 0.005s per OpenAI adapter test)
- Replace hardcoded sleep(500ms)/sleep(200ms)/sleep(100ms) in server and
integration tests with 10ms poll loops (0.2-0.5s → 0.02-0.03s each)
- Add env_clear() to ullm prompt tests to prevent .env from triggering real
Anthropic API calls (0.45s → 0.15s)

Add status, preferred_label, and suggested_next_ids fields to the
StageCompleted event so pipeline flow decisions are visible in CLI
output and the web UI, making it easier to debug why a pipeline
took a particular path.

ParallelHandler and SubPipelineHandler needed Arc<HandlerRegistry> at
construction time but also lived inside the registry, creating a circular
dependency. The previous fix special-cased ParallelHandler as a separate
field on PipelineEngine with a resolve_handler() override.
Instead, add an EngineServices struct (registry + emitter) passed through
Handler::execute(). ParallelHandler and SubPipelineHandler become unit
structs that get what they need at execution time. No special-casing,
both register normally in default_registry() like every other handler.

The spec says "exactly one" exit node in the shape table (line 184),
exit handler docs (line 648), and test criteria (line 1834). The lint
rule table (line 1437) says "at least one" but is the minority. The
previous commit incorrectly reverted this — the terminal node change
was not causing the test failures (all three were from retry-on-Fail).

Revert two incorrect behavioral changes introduced in ceaa9bf:
1. StageStatus::Fail must return immediately, not retry. Fail is a
deliberate routing outcome (e.g. to take a "fail" edge). Retrying it
caused conditional_branching and manager_loop tests to hang.
2. Pipelines can legitimately have multiple terminal nodes. The
"exactly one" constraint broke branching_loop_back_on_failure.
Restore "at least one" validation.

The parallel handler was never registered in default_registry() due to a
circular dependency (ParallelHandler::new needs Arc<HandlerRegistry>).
Break the cycle by storing ParallelHandler as a separate field on
PipelineEngine, created after Arc-wrapping the registry and emitter.

When CodergenHandler receives CodergenResult::Text, it now extracts
preferred_next_label, suggested_next_ids, and context_updates from
the last JSON object in the response. This enables edge selection
via condition matching and preferred label instead of always falling
through to unconditional edges.

Updates the default Gemini model from gemini-3-pro-preview to
gemini-3.1-pro-preview across agent, attractor, and ullm CLIs.
Adds "Using model:" output to stderr in both agent and ullm CLIs
so users can see which model is being used.

When --docker is passed, agent tools execute inside a Docker container
via DockerExecutionEnvironment instead of running on the host. The host
working directory is bind-mounted into the container at /workspace.

Adds a list endpoint that returns all in-memory pipelines with their
status, and a "Recent Pipelines" section in the start form that polls
every 3s so users can navigate to any pipeline started since server launch.

ApiQuestion now includes options and allow_freeform fields so API clients
can render multiple-choice questions. submit_answer accepts an optional
selected_option_key to produce AnswerValue::Selected instead of always
creating AnswerValue::Text.

The handler was converting all backend errors into Ok(Outcome::fail(...)),
which the engine treats as a terminal result. Retryable errors (timeouts,
network failures) are now propagated as Err so the engine retry loop kicks in.

Move ANSI Styles struct from agent/cli.rs into a shared terminal crate
so both binaries can use it. Add green and yellow color codes. Prettify
all attractor CLI output: bold headers, colored diagnostics by severity,
green/red status, yellow warnings, dimmed event details, and styled
interviewer prompts. Move pipeline status output from stdout to stderr.

Stores DOT source in ManagedPipeline and pipes it through `dot -Tsvg`
on request. Returns image/svg+xml on success, 502 if graphviz is
unavailable, 404 if pipeline not found. Resolves spec gap #1.

Add a [[bin]] target to the attractor crate with two subcommands:
- `attractor validate <pipeline.dot>` -- parse and validate only
- `attractor run <pipeline.dot>` -- full pipeline execution with LLM backend
The CLI supports --dry-run, --auto-approve, --resume, --model, --provider,
and two-level verbosity (-v one-line summaries, -vv full event details).
Extracts a shared `default_registry()` function in handler/mod.rs so both
the CLI and server can build a fully-wired HandlerRegistry without
duplicating handler registration boilerplate.
The AgentBackend in cli/backend.rs implements CodergenBackend by creating
a coding-agent-loop Session per node invocation, giving LLM nodes access
to file and shell tools.

Closes the subgraph class derivation test gap by adding a parse() pipeline
test that verifies DOT subgraph labels produce correct CSS-like classes on
contained nodes. Updates gap analysis to remove resolved items, add spec
contradictions section, and narrow remaining gaps to SVG rendering and
retry predicate customization.

- Gap 1: Real preamble synthesis per fidelity mode (truncate, compact,
summary:low/medium/high) in new preamble.rs module, replacing placeholder
- Gap 2: Pass thread_id to CodergenBackend.run() so backends can reuse
LLM sessions across nodes sharing the same thread
- Gap 7: Engine cancellation via AtomicBool token checked between nodes,
wired to server cancel endpoint, new Cancelled error variant
- Gap 8: RecordingInterviewer serialization (to_json/from_json, file I/O)
and new ReplayInterviewer for replaying recorded Q&A sessions
- Gap 12: Preset retry policies selectable from DOT via retry_policy attr
(none, standard, aggressive, linear, patient)
- Gap 15: Engine calls Interviewer.inform() at pipeline start, stage
start, and stage complete lifecycle points
37 new tests (450 unit + 49 integration, all passing).

Add SubPipelineHandler (handler/sub_pipeline.rs) that inline-executes a parsed
sub-graph within the same engine, reading DOT source from node attributes and
propagating context diffs back to the parent pipeline.
Add GraphMergeTransform (transform.rs) that merges nodes and edges from secondary
graphs into a primary graph with namespace-prefixed IDs to avoid collisions.
Add WebInterviewer (interviewer/web.rs) backed by oneshot channels for async
question/answer flow, and HTTP server (server.rs) with 8 axum endpoints behind
a "server" feature flag for pipeline management and human-in-the-loop via web.
Fix tempfile dev-dependency usage in server production code by using std::env::temp_dir.
