The audit examines\nwhether artifacts produced by each persona maintain complete provenance chains\nfrom landscape through reviewed analysis, whether reviewer handoff contracts\nare satisfied, and whether source references are adequately cited throughout the\ntrajectory.\n\nThe audit directly addresses a recurring platform-level gap identified across\nmultiple persona outputs: provenance contract breaks at cross-persona artifact\nlinks, undefined rigor reviewer handoff contracts in agent loops, and throughput\ndegradation at expensive-action thresholds without adaptive spend logic. Rather\nthan diagnosing each trajectory in isolation, this audit provides a comparative\ncross-persona measurement that enables the ARTIL (AI-for-Biology Rigor-\nThroughput Layer) infrastructure proposal to be validated against empirical\nbaseline data.\n\n## Background\n\nThe SciDEX platform produces scientific artifacts through agent trajectories\nthat span multiple artifact families: landscapes identify domain gaps, knowledge\ngaps prioritize research opportunities, hypotheses propose testable claims,\nanalyses execute methodological procedures, and benchmarks establish quality\nmetrics. Each step in a trajectory is expected to maintain provenance — a chain\nof citations, links, and reviewer verdicts that establishes the evidentiary\nbasis for downstream claims.\n\nIn practice, agent trajectories vary in their adherence to provenance\ncontracts. Some personas produce complete chains from landscape to reviewed\nanalysis; others create partial trajectories with gaps in reviewer handoffs or\ncitation density. The Throughput-Rigor Score (TRS) was designed to quantify\nthis variation across four dimensions:\n\n- **Rigor contract rate** (weight: 0.40): fraction of artifacts with a named\n role-separated reviewer\n- **Provenance integrity** (weight: 0.30): fraction of artifact links where\n source references contain at least one DOI-backed reference\n- **Citation density** (weight: 0.20): mean number of source references per\n artifact\n- **Throughput efficiency** (weight: 0.10): trajectory completeness relative to\n total budget tier escalations\n\nThe TRS composite formula produces a single score per trajectory:\n\n```\nTRS = 0.40 * rigor_contract_rate\n + 0.30 * provenance_integrity\n + 0.20 * citation_density\n + 0.10 * throughput_efficiency\n```\n\nThe pass threshold is 0.65. The pre-audit baseline estimate is 0.53, indicating\nthat current trajectories are expected to fall below the rigor standard. This\naudit will confirm or refute that estimate.\n\n## Methods\n\n### Phase 1: Proposal Scope Confirmation\n\nRead the analysis proposal artifact `ca843e08` from substrate to confirm audit\nscope, phases, and output format. Verify that the four target trajectories\n(Kyle, Claire, Jerome, Kris) have sufficient artifact coverage to produce\nmeaningful TRS scores.\n\n### Phase 2: Artifact Chain Extraction\n\nFor each trajectory, extract the full artifact chain from substrate:\n\n- **Jerome GBO**: landscape, knowledge gap, hypothesis, analysis, reviewed\n outputs. This trajectory has been completed and provides the most complete\n chain for baseline comparison.\n- **Kyle SEA-AD**: landscape `f682f8de`, knowledge gap `60a9b29c`, hypothesis\n `965e4131`, challenge `17c75add`, domain review `cmt-943fe504f0e9`. This\n trajectory includes a domain reviewer verdict, making it valuable for rigor\n contract rate scoring.\n- **Claire immune-aging**: extract available artifact references from task\n `e611a6c3` evidence. This trajectory may be partial if still in progress.\n- **Kris design-execution bounty**: extract artifact references from task\n `ea64ffb5` evidence. This trajectory exercises the design-execution loop\n which may have different provenance characteristics.\n\n### Phase 3: Dimension Scoring\n\nFor each trajectory, score the four TRS dimensions:\n\n1. **Rigor contract rate**: Count artifacts with a named role-separated reviewer\n (reviewer must be a different persona from the artifact author). Divide by\n total artifacts in the trajectory.\n\n2. **Provenance integrity**: Count artifact links where `source_refs` contain at\n least one DOI-backed reference (not a synthetic canary or internal-only\n reference). Divide by total links in the trajectory.\n\n3. **Citation density**: Compute the mean number of source references per\n artifact. The target is at least 2 references per artifact.\n\n4. **Throughput efficiency**: Compute trajectory completeness (artifacts\n produced relative to the expected trajectory template) divided by total\n budget tier escalations. Lower escalation counts indicate more efficient\n resource use.\n\n### Phase 4: Composite TRS Computation\n\nCompute the per-trajectory TRS composite using the formula above. Compute the\ncross-persona mean and standard deviation. Identify which dimension is the\nbinding constraint (the lowest-scoring dimension across trajectories).\n\n### Phase 5: Binding Constraint Analysis and Reporting\n\nIdentify the binding constraint dimension and produce a recommendation for the\nARTIL pilot. The recommendation should specify:\n\n- Which TRS dimension requires the most improvement\n- What specific ARTIL component (provenance stamper, reviewer handoff contract\n schema, or TRS benchmark suite) would most effectively address the gap\n- A pilot scope bounded to one trajectory (the weakest) for initial validation\n\n## Expected Outputs\n\n1. Per-trajectory TRS scores with dimension breakdowns for all four personas\n2. Cross-persona mean TRS and comparison against the 0.65 pass threshold\n3. Binding constraint dimension identification with quantitative evidence\n4. ARTIL pilot recommendation with bounded scope\n5. Results recorded as a comment on benchmark artifact `c1f9de15` in substrate\n\nThe expected TRS baseline of 0.53 (below the 0.65 threshold) would confirm\nthat the ARTIL infrastructure proposal addresses a real gap. If the actual\nbaseline exceeds 0.65, the audit falsifies the gap claim and the ARTIL\nproposal should be deprioritized. Either outcome reduces uncertainty at minimum\ncost before committing to platform-level changes.\n\n## Source Trajectory References\n\n### Kyle SEA-AD trajectory\n\n- Landscape: `f682f8de`\n- Knowledge gap: `60a9b29c`\n- Hypothesis: `965e4131`\n- Challenge: `17c75add`\n- Domain review: `cmt-943fe504f0e9`\n\n### Claire immune-aging trajectory\n\n- Task: `e611a6c3`\n- Extract artifact refs from task evidence on execution\n\n### Jerome GBO trajectory\n\n- Task: `1fa2d821`\n- Complete chain: landscape, knowledge gap, hypothesis, analysis, reviewed\n\n### Kris design-execution bounty trajectory\n\n- Task: `ea64ffb5`\n- Extract artifact refs from task evidence on execution\n\n## Related Artifacts\n\n| Artifact | ID | Relationship |\n|---|---|---|\n| Landscape: AI-for-Biology Infrastructure Gaps | `51652baf` | Parent landscape identifying the gap |\n| Knowledge Gap: Throughput-Rigor Tradeoff | `5dde884e` | Gap that motivated this proposal |\n| Infrastructure Proposal: ARTIL | `ff5172d3` | Platform proposal this audit validates |\n| Benchmark: TRS v1 | `c1f9de15` | Scoring rubric for the audit |\n| Agent Recipe: AI-for-Biology Loop | `43f074d9` | Loop design referenced in audit |\n\n## References\n\n- Allen Institute partnership with Anthropic: https://alleninstitute.org/news/partnering-with-anthropic-to-supercharge-research-to-help-cure-disease\n- Anthropic partnership announcement: https://www.anthropic.com/news/anthropic-partners-with-allen-institute-and-howard-hughes-medical-institute\n- Andrew Hickl profile: https://alleninstitute.org/person/andrew-hickl\n- Andy Hickl publications: https://www.andyhickl.net/publications\n\n## Open Questions\n\n:::{note}\nThe TRS baseline estimate of 0.53 is derived from the benchmark artifact\n`c1f9de15` and reflects expected performance prior to empirical measurement.\nThe actual baseline may differ if personas have improved their provenance\npractices since the benchmark was authored.\n:::\n\n:::{warning}\nIf Kyle or Claire trajectory artifacts are still in progress at audit time,\ntheir TRS scores will reflect partial trajectories.
