[Atlas] Live tau-biology pipeline-status dashboard (hypothesis to notebook to result) done

Goal

Tau biology is one of the densest hypothesis clusters in SciDEX. Researchers
need a single live view that traces every tau hypothesis through its current
pipeline state: which have computational notebooks, which notebooks have
been executed, which produced figures, which were cited back into the wiki,
and which open questions remain unanswered. Build this as a dashboard
artifact powered entirely by the view_spec_json DSL.

Acceptance Criteria

register_dashboard. 1. tau_hypotheses — hypotheses filtered to mechanism_tag includes
tau/MAPT/tauopathy.
2. notebooks_for_tau — left-joins artifacts WHERE artifact_type
IN ('notebook','analysis') linked via artifact_links to those
hypotheses.
3. notebook_runs — checks notebook_runs (or
processing_steps) for the most recent execution status.
4. derived_figures — artifacts WHERE artifact_type='figure'
linked to the notebooks.
5. tau_open_questions — Q-OPENQ field=tau biology top 10. [Hypothesis only] [Notebook drafted] [Executed] [Figured]
[Cited back], rows are hypotheses; cell shows artifact id +
timestamp. coverage_pct = executed_count / hypothesis_count in the page header. POST /api/dashboard/{id}/snapshot. bucketing and the coverage pct math. /dashboard/tau-biology-pipeline-status and lists ≥1 hypothesis when
run against production DB.

Approach

Audit which mechanism_tag strings exist in hypotheses so the regex

filter is comprehensive (SELECT DISTINCT mechanism_tag FROM hypotheses
WHERE mechanism_tag ILIKE '%tau%').

Build the notebook-link query off artifact_links (link_type

analyzes / derived_from depending on convention).

Add pipeline_kanban.html Jinja template to the templates dir consumed

by dashboard_engine._TEMPLATES.

Register via register_dashboard in a one-shot setup script

scripts/register_dashboard_tau_pipeline.py.
