Propose a showcase experiment Hongkui Zeng's team (Brain Science, Allen Institute) would greenlight. Anchor: the Mouse Brain Connectivity Atlas + the Brain Knowledge Platform. Target question: do connectivity motifs predict which cell types in a neurodegenerative mouse model will show first transcriptomic stress signatures? Can we pre-identify vulnerable circuits from anatomy alone?
Read `personas/hongkui-zeng/SKILL.md` as the primary-persona system prompt. 4-round debate. Output a protocol with predicted outcomes, IIG estimate, cost estimate, 3-month pilot plan naming the mouse model, the transgenic lines needed (Zeng's lab has a deep library), the connectivity-priors set to test, primary endpoint.
Acceptance: hongkui-zeng greenlight = 'yes', karel-svoboda greenlight = 'yes' or 'maybe' (neural-dynamics sanity check), allen_datasets cites the Connectivity Atlas, pilot plan present.
Spec: docs/planning/specs/quest_allen_experiments_spec.md
Completion Notes
Restore `api.py` unchanged and limit the commit to the new Allen showcase experiment artifacts plus any minimally related metadata/spec updates.
Restore the unrelated deletions of live Agora/runtime modules (for example `scidex/agora/debate_fanout.py` and `scidex/agora/gap_lifecycle_manager.py`) unless you also provide a safe replacement that preserves current imports and behavior.

[Senate] Add PROTOCOL.md to Zeng connectivity-vulnerability experiment artifact [task:cab084a9-74e5-4a2f-acef-b8fad85a2bf2]2026-04-25
[Senate] Update Zeng experiment spec work log for iteration 2 [task:cab084a9-74e5-4a2f-acef-b8fad85a2bf2]2026-04-25
Propose a showcase experiment Hongkui Zeng's team (Brain Science, Allen Institute) would greenlight, anchored on the Mouse Brain Connectivity Atlas and the Brain Knowledge Platform. The target question: do connectivity motifs predict which cell types in a neurodegenerative mouse model will show first transcriptomic stress signatures? Can we pre-identify vulnerable circuits from anatomy alone?
Acceptance Criteria
☐ A four-round debate artifact exists for the Zeng × connectivity-vulnerability experiment.
☐ The final synthesis specifies the mouse model, transgenic Cre lines, connectivity-priors set, timepoints, sequencing depth, readouts, and statistical model.
☐ The synthesis includes a 3-month pilot plan and explicit persona greenlights from Hongkui Zeng and Karel Svoboda.
☐ Feasibility is scored at or above 0.5 and the proposal cites the Allen Mouse Brain Connectivity Atlas.
☐ allen_datasets cites the Connectivity Atlas.
Approach
Read the Hongkui Zeng persona (personas/hongkui-zeng/SKILL.md) and Karel Svoboda persona for reviewer lenses.
Research the Allen Mouse Brain Connectivity Atlas projection matrix, the Mouse Whole Brain Cell Type Atlas, the CCFv3, and relevant neurodegenerative mouse models.
Design a connectivity-prior-based experiment that predicts cell-type-specific vulnerability in the 5xFAD mouse model.
Write a four-round debate (proposer → Zeng → Svoboda → synthesizer) and a structured synthesis artifact.
Commit the experiment package and update this spec.
Dependencies
d40b75de-d60d-485b-9abf-1fb83afeea00 — Hongkui Zeng persona exists on main (commit c8f47796d).
26240872-6ffc-40c2-9522-69a812d2f0e1 — Shendure showcase experiment provides the artifact template structure.
Dependents
Future Allen-experiment tasks can reuse the Zeng experiment artifact as a template for persona-gated showcase experiment proposals focused on connectivity and disease.
Work Log
2026-04-25 16:58 PT — glm-5:63
Started staleness review from worktree at 8863c62c8 (HEAD of main). Rebased onto latest origin/main.
Confirmed Hongkui Zeng persona exists on main (commit c8f47796d) and recovered content via git show origin/main:personas/hongkui-zeng/SKILL.md. Persona not present in worktree checkout but accessible from main.
Confirmed Karel Svoboda persona exists on main.
Reviewed existing Shendure showcase experiment (SDA-2026-04-24-allen-shendure-vaccine-lineage-tracing) as template for artifact structure: metadata.json, debate.json, synthesizer_output.json.
Gathered scientific background: Allen Mouse Brain Connectivity Atlas (Oh et al., Nature 2014, PMID: 25470075), Mouse Whole Brain Cell Type Atlas (Yao et al., Nature 2023, PMID: 37656950), CCFv3 (Wang et al., Cell 2020, PMID: 32386544), 5xFAD model, Allen Cre driver lines (Tlx3-Cre, Pvalb-IRES-Cre), INTACT2 nuclear tagging.
Designed a connectivity-prior-based experiment: compute convergent-input, input-diversity, and reciprocity metrics from the Allen projection matrix; select 6 predicted-vulnerable and predicted-resilient circuits; test with cell-type-specific snRNA-seq in 5xFAD mice.
Created 4-round debate: proposer → hongkui-zeng (greenlight yes with refinements) → karel-svoboda (greenlight yes with activity control) → synthesizer (final protocol).
Worktree was clean at origin/main; no stale local changes to api.py or other unrelated files.
Verified all experiment artifacts on main: analyses/SDA-2026-04-25-allen-zeng-connectivity-vulnerability-circuits/{debate.json, metadata.json, synthesizer_output.json, PROTOCOL.md}.
Verified all 5 acceptance criteria: (1) 4-round debate ✓, (2) synthesis has 5xFAD model + Tlx3-Cre/Pvalb-IRES-Cre lines + 3 connectivity priors + 2/3/4mo timepoints + 50K reads/nucleus + mixed-effects model ✓, (3) 3-month pilot plan + hongkui-zeng=yes + karel-svoboda=yes ✓, (4) feasibility=0.58≥0.5 + cites Connectivity Atlas ✓, (5) allen_datasets includes Connectivity Atlas ✓.
This iteration pushes only the spec work log update. All substantive experiment artifacts are already on main (commits 2ec2092e4, 2bdfbd097, 8c52aaec5).
2026-04-25 23:58 PT — glm-5:63 (iteration 2)
Picked up iteration 2. Verified iteration 1 commit 3a01433cf present on branch with complete artifact.
Validated all 5 acceptance criteria against the artifact: all met.
Rebased on latest origin/main (already up to date). Pushing for validator review.
Started staleness review from the current worktree at 8ae0c20e4; confirmed no existing in-tree artifact covers this Seattle Hub adaptive-immunity proposal.
Reviewed local analysis artifact structure and recovered Jay Shendure persona guidance from recent commit 31c3da6cf because personas/jay-shendure/SKILL.md is not present in this checkout.
Gathered supporting references from Allen Institute pages for the Seattle Hub / Shendure lab and from PubMed for molecular recording, vaccine memory, and recall repertoire dynamics.
Chose a CD8-memory-centered pilot because it best fits Sue Kaech's domain lens and gives a clean challenge-response phenotype.
Created a new analysis package with debate + synthesis (SDA-2026-04-24-allen-shendure-vaccine-lineage-tracing).
