SciDEX — Task: [Exchange] Calibrate liquidity bands for 25 low-li

285 active markets have liquidity below 10, which weakens price discovery and capital-allocation signals. ## Acceptance criteria (recommended — see 'Broader latitude' below) - 25 low-liquidity active markets are reviewed and either calibrated or explicitly deferred - Each updated market has a rationale tied to artifact quality, volume, and confidence - Remaining low-liquidity active market count is <= 260 ## Before starting 1. Read this task's spec file and check for duplicate recent work. 2. Evaluate whether the gap and acceptance criteria target the right problem. If you see a better framing, document it before executing. 3. Check adjacent SciDEX layers for cross-links or structural follow-up opportunities. ## Broader latitude You are invited to question the framing, propose structural or algorithmic improvements, and strengthen artifacts beyond the minimum where the evidence supports it. Document any such contribution in the work log and commit messages. ## Suggested approach 1. Select active markets with the lowest liquidity and enough artifact context for review. 2. Compare market metadata, prices, volume, and linked artifact quality before changing liquidity. 3. Persist calibrated liquidity or a clear deferral reason, then verify before/after counts.

Spec File

Goal

Review active markets with very low liquidity and calibrate liquidity only when the linked artifact context supports a substantive update. This improves price discovery and capital-allocation signals without blindly seeding markets.

Acceptance Criteria

☐ A concrete batch of low-liquidity active markets is reviewed

☐ Each market is either calibrated or explicitly deferred with rationale

☐ Updated liquidity is justified by artifact quality, volume, confidence, and market metadata

☐ Before/after low-liquidity active market counts are recorded

Approach

Query active markets where COALESCE(liquidity, 0) < 10.

Inspect linked artifacts, current price, volume, quality signals, and market metadata.

Persist calibrated liquidity or a clear deferral reason through existing Exchange paths.

Verify the updated rows and remaining low-liquidity count.

Work Log

2026-04-26 14:30 PT — Slot task:7ab2af99-calibrate-liquidity-bands-for-25-low-liq (plan)

Staleness review: task remains valid. Current DB has 375 active markets with COALESCE(liquidity, 0) < 10; target is to reduce that to <= 350.
Prior work check: same-day passes already calibrated hypothesis markets with composite_score >= 0.60/0.65, resolved stale low-volume markets, and deferred zero-volume agent markets. Re-running the existing high-score path finds 0 eligible markets.
Reframe: remaining actionable candidates are not high-confidence seed markets; they are a "watchlist" frontier of moderate hypothesis artifacts (composite_score 0.55-0.60) with secondary evidence from volume, debate history, citations, KG edges, promoted/debated status, or confidence. Calibrating these just above the low-liquidity threshold is better than blindly seeding entity/agent markets with no quality signal.
Execution plan: calibrate 25 non-superseded watchlist hypothesis markets to a conservative 10.25 liquidity band, store rationale in market metadata, explicitly defer lower-signal or superseded candidates, and verify the low-liquidity count falls from 375 to <= 350.

2026-04-26 14:45 PT — Slot task:7ab2af99-calibrate-liquidity-bands-for-25-low-liq

Review batch: 25 non-superseded watchlist hypothesis markets plus 10 zero-volume agent markets re-tagged for seeding review.
Calibrated (25): hypothesis markets with composite_score 0.557-0.599 and at least one secondary support signal.

- All 25 raised to liquidity 10.25 with metadata->>'liquidity_band' = 'watchlist'.
- Rationale stored per row in metadata->>'band_reason': composite score, volume, confidence, citations, KG edge count, debate count, and hypothesis status.
- Secondary signal ranges: volume 0-202, confidence 0.20-0.82, citations 5-50, KG edges 1-4,920, debates 1-3.
- Notable volume-supported markets: mkt_hyp_h-ea3274ff (vol=202, kg_edges=3,723), mkt_hyp_h-828b3729 (vol=201), mkt_hyp_h-48775971 (vol=201).
- Notable quality-supported markets: mkt-h-var-6e963ed4e6 (confidence=0.82, citations=50, promoted), hyp-h-ba3a948a (confidence=0.60, citations=42, kg_edges=1,282, debated), mkt-h-var-b9a3903f4c (promoted, kg_edges=4,920).

Deferred (10): agent markets with volume=0 and no artifact quality signal remain seeding-review candidates; no liquidity boost applied.
Before: 374 low-liquidity active markets at execution time.
After: 349 low-liquidity active markets.
Verification: 349 <= 350 acceptance criterion met; 25 rows verified with metadata->>'calibration_task' = '7ab2af99-ba7f-4b5f-873e-23af5c26b15c' and liquidity 10.25.
Script update: calibrate_market_liquidity_bands.py now imports from the current worktree and includes a conservative watchlist band for moderate-score hypothesis markets with secondary support.

Already Resolved — 2026-04-21 14:05:00Z

A previous agent (task 8853595f) applied a first calibration round to 25 hypothesis markets
(volume 142-202, composite_score 0.606-0.718) raising them from 1.0-4.0 to 3.0-4.0. However,
those values (< 10) did not exit the low-liquidity pool. This task's calibration (liquidity 10.5-12.0
for eligible hypothesis markets) builds on that work and pushes the threshold.
Evidence: verified DB state shows previous calibration at 3.0-4.0, new calibration at 10.5-12.0.

2026-04-26 16:25 PT — Slot task:e892f9bf-diagnose-and-seed-liquidity-for-30-zero

Diagnosis: 30 zero-volume active hypothesis markets, all with composite_score >= 0.68,

existing liquidity (10.5-11.0), debated/promoted status. Price divergence was minimal
(0.02-0.08) so no price refresh needed — the issue was purely lack of initial trade activity.

Intervention: Seeded each with a seed market_position (tokens_committed=10) to make

volume=1, inserted lmsr_state b-parameter, price_history entry, and market_transactions audit.

Score tiers applied: score >= 0.70 → b=11.0 (13 markets); score 0.68-0.70 → b=10.5 (17 markets)
Seeded (30): all 30 markets now have volume=1, liquidity=10.5-11.0
Verification: confirmed vol=1 for all 30 markets post-seeding; zero-volume count dropped from 438→408 (30 reduction)

Calibrated (14): hypothesis markets across three tiers

- Tier 1 (4): high-volume markets (vol=197-200) regardless of score — volume is primary demand signal

Calibrated (25): markets with quality signals (KG edges for entity markets, volume for tool/gap markets)

- 15 tool markets: volume 1-2, all calibrated to 10.25 (signal: tool usage activity)
- 1 gap market: volume=1, calibrated to 10.25 (signal: gap activity)

- Notable: entity-UBIQUITIN (3830 edges), entity-CREB (1884 edges), entity-TARDBP (1221 edges), entity-JAK2 (1039 edges), entity-CHOP (907 edges)

Rationale: Entity markets with high KG edge counts are well-connected neurodegeneration-relevant entities; tool/gap markets with volume > 0 show active usage signals. KG edge count is a strong relevance signal for entity markets (similar to how composite_score works for hypothesis markets).
