Dark-Alex-17 0ce2654173 feat(TASK-023): deep-research hardening — fail-safe scripts, fault fallbacks, pipeline notes
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.

"""Degrade-visibly marker for a dead source-vetting stage of deep-research.
Reached ONLY via vet_sources' `fallback:` route. Grounded in engine
behavior: on llm-node failure the engine writes "LLM node …failed: <chain>"
into `source_assessment` via the node's state_updates BEFORE routing to the
fallback. Vetting is a quality lane, not the product, so this path degrades
instead of failing closed: it records a PIPELINE-FAULT (surfaced later in
the report's Pipeline notes) and rewrites `source_assessment` to a neutral
"unvetted" note so downstream prompts (critique, synthesize) never carry
raw engine error text, then continues to `critique` — the stage
vet_sources' own `next` pointed to.
