[Agora] Generate falsifiable predictions for 25 hypotheses with none open analysis:7 reasoning:6

Goal

Generate concrete, falsifiable predictions for active hypotheses that currently have no prediction rows. Predictions make hypotheses testable and support preregistration, replication, and market resolution.

Acceptance Criteria

Approach

Select active hypotheses with predictions_count = 0, prioritizing high impact and confidence.

Derive predictions from mechanism, target, disease, evidence, and linked analyses.

Insert predictions through the standard DB path and update/verify prediction counts.

Inspect a sample for falsifiability and non-duplication.

• Task: [Agora] Generate falsifiable predictions for 25 hypotheses with none [task:00ff7671-4978-46b2-ae92-a1fa2271f442]
• Staleness review: Task is still relevant on current origin/main (cc28fc619).

Live DB check shows 737 proposed / promoted hypotheses with predictions_count = 0,
so the zero-prediction gap remains material.

• Iteration plan:

1. Query the current top-ranked 25 active hypotheses with zero predictions.
2. Generate 2 falsifiable predictions per hypothesis using the repo LLM path with
measurable outcome, timeframe, methodology, and falsification criteria.
3. Insert via the standard PostgreSQL write path with idempotent duplicate checks, then
recompute hypotheses.predictions_count.
4. Verify before/after zero-prediction counts and inspect a sample for quality/non-duplication.

• Structural note: Prior backfill scripts diverged on columns (confidence vs confidence_score)

and duplicate handling. This iteration will use the currently populated fields observed in live
hypothesis_predictions rows (confidence, methodology, created_by) and explicit text-level
duplicate checks to avoid re-inserting equivalent predictions for the same hypothesis.

• Execution: Added scripts/backfill_predictions_00ff7671.py with current-top-N selection,

targeted rerun support via --ids, and DB-backed predictions_count refresh support.
Ran a 2-hypothesis dry run successfully, then executed a 25-hypothesis live pass plus a
targeted recovery pass for three transient failures.

• Result: 50 new hypothesis_predictions rows inserted across 25 active hypotheses

(2 predictions each). Direct verification shows all 25 targeted hypotheses now have
predictions_count = 2 and actual COUNT(*) = 2 in hypothesis_predictions.

• Before / after:

- Initial system-wide zero-prediction count at run start: 741
- Current system-wide zero-prediction count after this iteration: 731
- Targeted hypothesis coverage: 25 / 25 hypotheses now falsifiable in the registry

• Recovery notes:

- First live pass inserted 44 predictions for 22 hypotheses; 2 hypotheses failed JSON parsing
and 1 hit a tuple lock timeout while updating hypotheses.
- Recovery rerun on h-cb692686e2, h-1b47a73770, and h-6ed7b5c8 completed successfully.
- Corrected two chemically inverted generated predictions in-place after audit:
replaced an invalid FK866 NAMPT-activation claim with NR/NMN supplementation, and replaced
a false sulfasalazine system Xc- activation claim with explicit SLC7A11 overexpression.

• Sample verification:

- h-cb692686e2 (tau missorting autonomous seeding): 2 predictions inserted after targeted rerun
- h-1b47a73770 (APOE4 lysosome-to-ER cholesterol transport): 2 predictions inserted after targeted rerun
- h-6ed7b5c8 (TREM2-APOE DAM recruitment): 2 predictions inserted after targeted rerun
- h-e59df37bd0 and h-dd0ccf93cb: audited and corrected mechanistic details in the inserted rows

• Task: [Agora] Generate falsifiable predictions for 25 hypotheses with none [task:68052fdf-22de-4d49-8806-5dbcaee8ba45]
• Staleness review: Task remains relevant. Live PostgreSQL check shows 447 active

(proposed / promoted) hypotheses still have predictions_count = 0, despite prior
successful backfill batches.

• Iteration plan:

1. Use the current top 25 active zero-prediction hypotheses ordered by composite_score.
2. Generate two falsifiable IF/THEN predictions per hypothesis with measurable outcome,
timeframe, model/cohort context, and decisive falsification criteria.
3. Insert through the standard PostgreSQL transaction path with text-level duplicate checks
and refresh hypotheses.predictions_count.
4. Verify before/after zero-prediction counts, target-level count agreement, and a sample
of inserted prediction quality.

• Dry run: scripts/backfill_predictions_68052fdf.py --limit 1 --dry-run --sleep 0

generated two valid predictions for h-56af4a2b91 and rolled back successfully; system-wide
zero-prediction count stayed at 447.

• Execution: Ran scripts/backfill_predictions_68052fdf.py --limit 25 --sleep 0.2.

The pass encountered transient malformed LLM JSON for h-56af4a2b91, but direct verification
showed that hypothesis already had two codex-created prediction rows from the same iteration.
The live pass inserted 24 additional prediction rows and refreshed stale predictions_count
values for 12 hypotheses whose rows appeared while the run was active.

• Result: 25 targeted active hypotheses now have linked predictions. Direct verification

shows every target has predictions_count = 2 and actual COUNT(*) = 2 in
hypothesis_predictions.

• Before / after:

- System-wide active zero-prediction count before this iteration: 447
- System-wide active zero-prediction count immediately after live pass: 422
- Current verification count after adjacent concurrent backfill activity: 417
- Targeted hypothesis coverage: 25 / 25 hypotheses now falsifiable

• Sample verification:

- h-56af4a2b91 (ganglioside-rich extracellular vesicles / alpha-synuclein): predictions
specify ganglioside depletion/reconstitution experiments with RT-QuIC, ThT fluorescence,
proteolytic fragmentation, and decisive no-difference falsification criteria.
- h-0fcf8ff993 (APOE4 astrocyte complement dysregulation): predictions specify C3aR/C5aR
antagonist and postmortem genotype-stratification tests with synaptic-density outcomes.
- h-6a4c716402 (TREM2 phagocytic receptor cascades): predictions specify TREM2 WT/KO
and R47H isogenic iPSC-microglia contrasts with pSyk, p62 phosphorylation, and phagocytic
index outcomes.

• Script hardening: Fixed the task-specific script's dry-run path before commit so future

--dry-run and --refresh-counts-only --dry-run executions avoid write statements rather
than relying on rollback behavior.

• Acceptance criteria: All 4 met for this slice — 25 hypotheses have linked

hypothesis_predictions rows, each sampled prediction has measurable IF/THEN outcome,
timeframe, methodology/provenance context, no target has duplicate-equivalent row counts,
and before/after zero-prediction counts are recorded above.

before/after zero-prediction counts recorded above. Zero-prediction count (391) remains
well below the ≤475 acceptance criterion established at task creation.

2026-04-26 15:03 PT — Slot codex:52 (iteration 3)

• Task: [Agora] Generate falsifiable predictions for 25 hypotheses with none [task:68052fdf-22de-4d49-8806-5dbcaee8ba45]
• Staleness review: Task remains relevant despite the prior two successful iterations for

this same task ID. Live PostgreSQL check shows 379 active (proposed / promoted) hypotheses
still had predictions_count = 0 at the start of review; adjacent concurrent work lowered
that to 377 before the dry run completed.

• Current repo state: Existing scripts/backfill_predictions_68052fdf.py is available on

the task branch and already implements top-N selection, LLM generation, text-level duplicate
checks, journaled PostgreSQL writes, and hypotheses.predictions_count refreshes.

• Dry run: python3 scripts/backfill_predictions_68052fdf.py --limit 1 --dry-run --sleep 0

generated two valid IF/THEN predictions for h-0f37721539 without changing the zero-prediction
count, confirming the dry-run path still avoids DB writes.

• Iteration plan:

1. Run the existing task script for the current top 25 active zero-prediction hypotheses.
2. Recover any transient LLM parse failures with targeted --ids reruns.
3. Verify target-level predictions_count matches actual hypothesis_predictions rows.
4. Record before/after counts and audit representative prediction quality for measurable
outcomes, timeframes, methodology/provenance context, and decisive falsification criteria.

• Execution: Ran python3 scripts/backfill_predictions_68052fdf.py --limit 25 --sleep 0.2.

The pass completed without LLM recovery reruns. It inserted 44 new hypothesis_predictions
rows and refreshed 3 stale predictions_count values where another prediction row already
existed for the target.

• Result: 25 / 25 targeted active hypotheses now have linked predictions. Direct verification

shows every target has predictions_count equal to actual COUNT(*) in
hypothesis_predictions; 24 targets have 2 predictions and hyp_test_852af3c6 has 1 existing
prediction after stale-count refresh.

• Before / after:

- Live staleness-review zero-prediction count: 379 active hypotheses
- Script run zero-prediction count before: 370 active hypotheses
- Script run zero-prediction count after: 343 active hypotheses
- Verification count after DB audit: 343 active hypotheses
- Active count mismatches after verification: 46, down from 47 at staleness review
- Targeted hypothesis coverage: 25 / 25 hypotheses now falsifiable

• Sample verification:

- h-cfcf4d4c0d (temporal cGAS-STING activation): predictions contrast early P50 vs
symptomatic P90 STING inhibition in SOD1-G93A mice with rotarod, survival, Iba1, and ChAT+
motor neuron endpoints plus decisive stage-specific falsification criteria.
- h-var-37b006000c (ketone-primed glymphatic tau clearance): predictions specify a
placebo-controlled ketone ester protocol in adults with EEG/GRIN2B outcomes and a 3xTg-AD
mouse protocol with phospho-tau and AQP4 polarization endpoints.
- h-9e877c49ba (SCFA / FFAR2 / NLRP3 alpha-synuclein pathology): predictions specify SCFA
supplementation and FFAR2 antagonism in alpha-synuclein mouse models with IL-1beta, pSyn
aggregate burden, and rotarod outcomes.

• Commit: 09923b2c5 — [Agora] Backfill falsifiable predictions for 20 zero-prediction hypotheses [task:96be61fa-a30d-4a0b-9501-248051ef3ab0]
• Pushed: git push origin HEAD
• Verification: All 4 acceptance criteria met — 20 hypotheses gained linked predictions, each prediction has IF/THEN format with measurable outcome + timeframe + methodology + falsification criteria, no duplicates via id-based ON CONFLICT DO NOTHING, before/after counts recorded above.
