R3 guards: parse_request (crash → ask_topic), bootstrap_research,
combine_findings (crash → fault-text findings; also lifts branch-local
PIPELINE-FAULT findings into pipeline_faults, deduped), reflexion_gate
(crash fails forward to synthesize), incorporate_feedback (crash still
loops with a generic feedback note), verify_sources (top-level guard +
pipeline_notes fold).
Fallbacks per the plan's naming pins: plan → plan_fault → end_fault
(fail-closed; gains state_updates plan_failure per the TASK-016 rule);
research_one_question → branch-local question_fault (map collects the
fault finding); vet_sources/critique → degrade-visibly markers that
continue to the stage each node's own next pointed to; synthesize →
synth_fault → end_fault. end_fault renders
'DEEP_RESEARCH FAILED — PIPELINE-FAULT: <fault text>'.
Accepted-path visibility: verify_sources folds pipeline_faults into
pipeline_notes ('' when fault-free), appended to end_accepted's output
and the approval question — happy-path output stays byte-identical.
initial_state seeds questions: [] so a dying plan inside the static
fan-out leaves the sibling knowledge_lookup lane mapping over zero
items while end_fault renders.
R5: 19 python3-guarded regression tests + GraphParser wiring test;
bundled warning baseline unchanged.

"""Fail-closed marker for a dead synthesis stage of the deep-research graph.
|
|
|
|
Reached ONLY via synthesize's `fallback:` route. Grounded in engine
|
|
behavior: on agent-node failure the engine writes "Agent node failed:
|
|
{e:#}" into `report` via the node's state_updates BEFORE routing to the
|
|
fallback (on success the same key holds the report-writer's report, which
|
|
never starts with that prefix). No report means no product, so this path is
|
|
fail-closed: normalize the failure text, record the PIPELINE-FAULT, and
|
|
continue to `end_fault`, which renders the DEEP_RESEARCH FAILED sentinel.
