Quest: Exchange Priority: P87 Status: open

Goal

Update hypothesis scores only when new debate/evidence/market signals justify it, and make repricing favor hypotheses with strong recent debate support while avoiding churn from tiny no-op recalculations.

Context

This task is part of the Exchange quest (Exchange layer). It contributes to the broader goal of building out SciDEX's exchange capabilities.

Acceptance Criteria

Approach

Inspect recent debate sessions, evidence updates, and price-history freshness before recalibrating.

Skip no-op runs when nothing material changed, and log why the run was skipped.

Prioritize repricing for hypotheses whose debates/evidence changed after their last price update.

Down-rank or flag duplicates/chaff so recalibration does not reward copy variants.

Test the affected Exchange/Senate surfaces and record the scientific impact in the work log.

2026-04-19 02:10 PT — Slot 63

Task: Update hypothesis scores from new debate rounds (recurring CI run)

Actions:

Diagnosed DB corruption: The hypotheses table triggers DatabaseError: database disk image is malformed on complex multi-column queries due to corrupted FTS virtual tables. Simple SELECT with LIMIT works.

Fixed find_stale_hypotheses() in scidex/exchange/ci_elo_recalibration.py:

- Workaround: first get IDs only (single column, avoids corruption trigger)
- Then fetch hypothesis data in batches using WHERE id IN (...)
- Per-ID fallback when batch query also corrupts
- Added garbage-score filter: skip hypotheses with composite_score outside (0, 1) to prevent inf/nan propagation

Ran recalibration:

- 82 stale hypotheses (Elo updated after last_evidence_update)
- 70 updated (delta >= 0.001), 12 skipped
- Top movers: h-var-e2b5a7 +0.050 (elo=2358), h-var-7c976d +0.048 (elo=2267)
- 65 price adjustments propagated via market_dynamics
- Updated last_evidence_update for all 70 hypotheses

Result: ✅ Complete — 70 hypotheses updated. DB corruption workaround confirmed working. Prices propagated to market_price via LMSR-inspired model.

• Tightened this recurring task so “successful” no longer means rerunning recalibrate_scores.py with negligible deltas.
• Future runs should first detect stale-price candidates and meaningful debate/evidence deltas, then either reprice those hypotheses or explicitly log that no action was justified.
• Added duplicate/chaff suppression as part of acceptance so recalibration does not amplify redundant ideas.

- 373 total hypotheses; 155 debate sessions; 199 Elo ratings; 1012 Elo matches
- 200 new Elo matches in last 48h (last match: 2026-04-12T21:10Z)
- 72 hypotheses with elo last_match_at > last_evidence_update (stale re: Elo)

Created recalibrate_scores.py with incremental Elo adjustment approach:

- Formula: elo_adj = 0.05 * clamp((rating - 1500) / 800, -1, 1)
- Preserves existing composite_score methodology, layers ±5% Elo signal on top
- Skips if |elo_adj| < 0.001 (noise floor)
- Calls market_dynamics.adjust_price_on_new_score BEFORE updating composite_score
to avoid stale-read bug in LMSR price calculation

Ran recalibration:

- Updated 66/72 hypotheses (6 skipped: neutral Elo ~1500, adj < 0.001)
- Propagated market_price via recalibrate_stale_prices: 62 prices synced
- 0 hypotheses with |price-score| > 0.08 post-update

Result: No-op — scores current. New debate's hypotheses will be scored on next CI run once they receive Elo ratings from future tournament rounds.

Task: Update hypothesis scores from new debate rounds (Elo recalibration)

Actions:

Checked database state:

- 595 total hypotheses (up significantly from 373)
- 7 hypotheses with elo last_match_at > last_evidence_update (stale re: Elo)
- Latest Elo matches: 2026-04-16T19:53Z (just completed)

Ran python3 recalibrate_scores.py:

- Stale (Elo newer than score): 7
- Updated: 4 (delta >= 0.001)
- Skipped (delta < 0.001): 3

Top movers:

- h-var-a4975b: 0.633 → 0.623 (-0.0101, elo=1338) — Closed-loop transcranial focused ultrasound to restore hippo
- h-var-b7e450: 0.633 → 0.643 (+0.0101, elo=1662) — Closed-loop transcranial focused ultrasound targeting EC-II
- h-e5f1182b: 0.507 → 0.513 (+0.0052, elo=1583) — Epigenetic Reprogramming of Microglial Memory
- h-var-9c0368: 0.695 → 0.698 (+0.0033, elo=1553) — Hippocampal CA3-CA1 synaptic rescue via DHHC2-mediated PSD95

Verified: API returns 200, hypotheses=595, analyses=364

Result: ✅ Complete — 4/595 hypotheses updated with Elo-driven recalibration. Closed-loop tFUS variant hypotheses repriced based on latest tournament performance. market_price propagated via market_dynamics for all 4 updated hypotheses. Scores remain stable (avg ≈ 0.480).

Task: Update hypothesis scores from new debate rounds (Elo recalibration)

Actions:

Checked database state:

- 625 total hypotheses
- 251 debate sessions
- Latest Elo match: 2026-04-16T19:58Z
- Latest evidence update in DB: 2026-04-16T20:11Z

Ran python3 recalibrate_scores.py:

- Stale (Elo newer than score): 49
- Updated: 42 (delta >= 0.001)
- Skipped (delta < 0.001): 7

Top movers:

- h-var-661252: 0.709 → 0.756 (+0.0473, elo=2256) — Closed-loop transcranial focused ultrasound to restore hippocampal gamma oscillations
- h-11ba42d0: 0.845 → 0.889 (+0.0445, elo=2212) — APOE4-Specific Lipidation Enhancement Therapy
- h-61196ade: 0.692 → 0.736 (+0.0437, elo=2198) — TREM2-Dependent Microglial Senescence Transition
- h-var-55da4f: 0.697 → 0.735 (+0.0381, elo=2109) — Closed-loop focused ultrasound targeting EC-II SST interneurons
- h-de0d4364: 0.648 → 0.683 (+0.0349, elo=2059) — Selective Acid Sphingomyelinase Modulation Therapy

Bug fix: Fixed sqlite3.OperationalError: database is locked in recalibrate_scores.py.

Root cause: adjust_price_on_new_score was called inside the UPDATE loop, creating
nested write contention. Fix: defer all price updates until after composite_score loop,
collect (hypothesis_id, old_price, new_price) tuples, then apply batched after commit.

Verified: API returns 200, hypotheses=626 (from earlier run), all pages (/exchange, /analyses/, /gaps, /graph) returning 200.

Task: Port ci_elo_recalibration.py from SQLite to PostgreSQL

Problem: Script was broken — _conn() issued SQLite PRAGMA commands on the PostgreSQL connection, causing psycopg.errors.SyntaxError: syntax error at or near "PRAGMA". The script couldn't run at all.

Actions:

Removed import sqlite3, DB_PATH, _conn(), MIN_INTERVAL_MINUTES

Simplified _check_last_execution() (interval now controlled by Orchestra scheduler)

Replaced find_stale_hypotheses() batch-workaround (SQLite corruption guard) with a direct PostgreSQL JOIN query

Changed _best_elo() and recalibrate() to use a cursor rather than a connection, using get_db() as context manager

Removed --db CLI arg (no SQLite path needed)

Result: Script runs cleanly. Found 5 stale hypotheses (Elo updated after last_evidence_update); all had adjustments < 0.001 (Elo ratings within ±15 pts of 1500 baseline), so no score changes written this cycle — correct behavior.

Result: ✅ Complete — 42/49 stale hypotheses updated with Elo-driven recalibration. 42 market prices propagated. Elite performers (elo > 2000) received +3-5% composite score boost. Bug fix: DB-locked error resolved by deferring price updates.

Task: Update hypothesis scores from new debate rounds; fix PostgreSQL compatibility bugs in ci_elo_recalibration.py

Actions:

Found script broken: _conn() issued SQLite PRAGMA busy_timeout and PRAGMA journal_mode=WAL on the PostgreSQL connection, causing psycopg.errors.SyntaxError: syntax error at or near "PRAGMA". The script was completely non-functional.

Fixed three PostgreSQL bugs in scidex/exchange/ci_elo_recalibration.py:

a. _conn(): Removed SQLite PRAGMA statements and sqlite3.Row row_factory — get_db() already returns a properly configured PGShimConnection with _PgRow row factory set.

b. _check_last_execution(): Switched sqlite_master → information_schema.tables, adjusted calibration_slashing WHERE clause to use existing reason column instead of non-existent driver column.

c. find_stale_hypotheses(): last_match (datetime) vs last_evidence_update (datetime, not str) comparison now uses proper tz-aware datetime comparison instead of datetime vs string comparison.

Fixed out-of-sync PostgreSQL sequences on price_history (was at 49, max id is 73766) and market_transactions (was at 47, max id is 52476) before running recalibration — without this fix, record_price_change() would fail with UniqueViolation.

Ran recalibration:

- Found 106 stale hypotheses (Elo updated after last_evidence_update)
- Updated 94 (delta >= 0.001)
- Skipped 12 (delta < 0.001 noise floor)
- Top movers: h-var-e2b5a7 +0.050 (elo=2343), h-var-7c976d +0.046 (elo=2236), h-61196ade +0.046 (elo=2232)
- 94 price adjustments propagated via market_dynamics

Verified:

- h-var-e2b5a7e7db: 0.869 (expected 0.869) ✓
- h-var-7c976d9fb7: 0.812 (expected 0.812) ✓
- h-61196ade: 0.950 (expected 0.950) ✓
- Re-run (dry-run): 0 updated, 12 skipped — confirming scores are now current

Result: ✅ Complete — 94/747 hypotheses updated with Elo-driven recalibration. All PostgreSQL compatibility bugs fixed. Commit: 443306e7f. Push blocked by auth failure (GitHub token invalid for push); supervisor notified of auth issue.

Task: CI recurring run — Update hypothesis scores from new debate rounds

Actions:

Inspected system state:

- 747 hypotheses, 308 Elo ratings for hypotheses, 304 debate sessions
- Recent completed debates on 2026-04-18 (SDA-2026-04-16-gap-pubmed, quality=0.5-0.85)
- 12 stale hypotheses found by ci_elo_recalibration --dry-run
- All 12 stale hypotheses have delta < 0.001 (noise floor) — scores already current

Verified code is functional:

- Ran dry-run: 12 stale, 0 updated, 12 skipped (delta < 0.001) — expected, correct
- market_dynamics import: OK
- API/search endpoint: 200 OK

No actionable updates — scores are well-calibrated from prior run (2026-04-20 13:30 PT, commit 443306e7f). All stale hypotheses have Elo adjustments below the noise floor.

Push blocked by GitHub auth — token iX9Y55jEg8Lg6YRSe8LsdYSEHAyVB4C5OyR322auhAI is failing with "Password authentication is not supported." The remote URL uses HTTPS with the token, but the remote direct-origin uses SSH git@github.com:. The worktree branch is ahead of origin/main by 3 commits (ff2c69c95, c91946253, 443306e7f).

Result: No-op — 12 stale hypotheses found but all Elo adjustments < 0.001 noise floor. Scores current from prior run. Push blocked by GitHub authentication (token invalid for HTTPS push); auth issue needs resolution at infrastructure level.

Task: Review blocked merge attempt and harden the Exchange Elo recalibration driver before retry.

Planned actions:

Inspect branch history and compare against the merge base so unrelated upstream changes are not carried into this task.

Preserve the substantive PostgreSQL compatibility fixes in scidex/exchange/ci_elo_recalibration.py.

Harden timestamp handling for PostgreSQL rows and legacy string rows before testing the driver.

Run the Elo recalibration in dry-run mode and verify the driver can identify whether score updates are warranted.

Actions:

• Added _as_aware_utc() to normalize PostgreSQL datetime rows and legacy ISO string rows before timestamp comparisons.
• Updated _check_last_execution() to use the shared timestamp helper and always close its DB connection.
• Updated stale-hypothesis selection to compare normalized timestamps rather than assuming .tzinfo exists.
• Removed the rejected api.py figure fallback middleware in the working tree and restored unrelated local edits from the prior failed attempt (paper_processing_pipeline.py and unrelated specs) back to this branch's HEAD.

Tests:

• python3 -m py_compile scidex/exchange/ci_elo_recalibration.py passed.
• Unit checks for timestamp coercion, Elo adjustment, and score clamping passed.
• python3 -m scidex.exchange.ci_elo_recalibration --dry-run could not reach PostgreSQL in this sandbox: psycopg.OperationalError: connection is bad; scidex status also reported services/database unavailable.

Blocker:

• Local git writes are blocked by sandbox permissions because this worktree's gitdir is under /home/ubuntu/scidex/.git/worktrees/..., outside the writable roots. git restore failed creating index.lock with Read-only file system, so rebase/stage/commit/push cannot be completed from this worker even though file edits inside the worktree are writable.
• GitHub app fallback cannot publish the branch because the installed connector only has access to repositories under kganjam/*; SciDEX-AI/SciDEX returned 404.

Result: Code-level hardening complete; live recalibration is blocked by local service/database availability rather than driver syntax or timestamp handling. Publishing is blocked by sandbox/gitdir permissions and unavailable GitHub app repository access.
