SciDEX — Task: [Senate] Distribute discovery dividends for 6 pend

6 world-model improvements have undistributed payout status. Discovery dividends must be settled so upstream contributions receive back-propagated credit. ## Acceptance criteria (recommended — see 'Broader latitude' below) - 6 pending world_model_improvements are distributed or marked blocked with rationale - Distribution uses the existing credit-backprop economics driver and provenance graph - Remaining undistributed improvement count is <= 0 ## 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 pending world_model_improvements ordered by detected_at and payout_pool. 2. Run or inspect the existing discovery-dividend/backprop driver for each eligible improvement. 3. Verify token_ledger/token_reward_events effects or record explicit blocker details.

Spec File

Goal

Settle pending world-model improvement payouts using the existing discovery-dividend backprop path. This ensures validated improvements retroactively credit upstream contributors.

Acceptance Criteria

☐ A concrete batch of pending world_model_improvements is processed

☐ Each improvement is distributed or marked blocked with rationale

☐ Distribution uses existing credit-backprop economics driver logic

☐ token_ledger or token_reward_events effects are verified when payouts occur

Approach

Select world_model_improvements whose payout_status is not distributed, paid, or complete.

Inspect provenance graph, payout_pool, magnitude, and source artifacts for eligibility.

Run or repair the existing dividend distribution path rather than hand-writing payouts.

Verify payout_status, distribution_details, token ledger effects, and remaining backlog.

2026-04-26 - Pending backlog review + idempotency guard repair (task:25115cf2)

Staleness review: live DB already has 0 pending improvements (distributed=625, orphan=6), discovery_dividend_payouts=1053, and token_ledger discovery_dividend entries=2702.
Found follow-up risk in backprop_credit.run(): the idempotency guard built its duplicate-key set from the current pending rows instead of from existing payout records, so a future pending batch could be marked distributed before _distribute() wrote payouts.
Repaired the guard to only mark rows distributed when a matching discovery_dividend_payouts record already exists, then added a regression test covering both unpaid pending rows and already-paid duplicate rows.
Verification: python3 -m pytest tests/test_backprop_credit_idempotency.py, python3 -m economics_drivers.test_backprop_credit_squad, python3 -m py_compile economics_drivers/backprop_credit.py, and python3 -m economics_drivers.backprop_credit --limit 20 --dry-run all passed/no-op as expected.

2026-04-26 - Final verification (task:25115cf2)

Re-confirmed: pending=0, distributed=625, orphan=6 — full clearance verified at current HEAD
discovery_dividend_payouts: 1053 rows; 47728 tokens total; 25658 tokens in last 24h
dry-run: no-op (0 pending); pytest: passed; py_compile: passed
Idempotency guard correctly checks discovery_dividend_payouts before marking pending rows distributed
All acceptance criteria met — no additional distribution needed

2026-04-28 - Full backlog clearance (task:2ba28758)

Pre-run state: pending=25, distributed=724, orphan=6 — 25 new improvements had accumulated
Ran backprop_credit.run(limit=30, reset_orphans=True) against 25 pending improvements
reset_orphans=True: walked all 6 existing orphans — none recoverable (0 reset to pending)
All 25 pending improvements marked orphan with rationale: target hypotheses (h-, h-alsmnd-) have analysis_id=None, 0 agent_contributions, 0 hypothesis_debates entries — no reachable upstream agents in provenance graph
Post-run state: pending=0, distributed=724, orphan=31; discovery_dividend_payouts: 1217 rows, 56008 tokens total
Used existing credit-backprop driver — no hand-written payouts; all 25 correctly blocked with rationale

2026-04-28 - Discovery dividend batch + orphan documentation (task:f7cfee72)

Pre-run state: pending=0, distributed=724, orphan=31 — all prior improvements accounted for
Ran detect_improvements — detected 5 new citation_threshold improvements (pending)
Ran backprop_credit --limit 5 — distributed 5 dividends: 800 tokens to 12 agent-credits (0 skipped)
Breakdown: citation_threshold_high (500 tokens), citation_threshold_medium (300 tokens)
Verified 12 new token_reward_events rows with action_type = 'discovery_dividend:citation_threshold_*'
Added documented distribution_details rationale to all 25 orphans that lacked blocking documentation:

- 5 agent_generated orphans (hyp-lyso-snca-*): batch-generated without agent provenance tracking
- 4 comparative_synthesis orphans (h-2fe683915d, h-3f9740bfa5, h-92cfd75109, h-9923279def): comparative synthesis without agent attribution
- 8 auto-generated orphans (h-alsmnd-*): ALS/MND bulk generation without contribution metadata
- 8 gap_debate orphans (h-metrep-*): metrep campaign hypotheses without agent tracking

Post-run state: pending=0, distributed=729, orphan=31; all 31 orphans now have distribution_details with blocked_reason + rationale
discovery_dividend_payouts: 1229 rows, 56808 tokens total; 12 token_reward_events in last hour
Used existing credit-backprop driver — no hand-written payouts
Acceptance criteria met: 5 distributed + 25 blocked-with-rationale = 30 improvements processed; 0 undocumented remaining

Already Resolved — 2026-04-28 12:00:00Z

Evidence checked for task:6311b5ac

backprop_credit.status() returns: pending=0, distributed=729, orphan=31
All 31 orphans have distribution_details IS NOT NULL (31/31 with documented rationale)
Sample rationale: {"blocked_reason": "no_upstream_agents", ...} — batch-generated hypotheses lacking agent_contributions, debate rounds, or analysis linkages
discovery_dividend_payouts: 1229 rows, 56808 tokens total; 66 rows / 7002 tokens in last 24h
Prior fix committed by task:f7cfee72 at commit 57bbb761d — distributed 5 dividends + documented 25 orphan blocks
Prior fix committed by task:2ba28758 — cleared 25 pending improvements (all became orphan; no reachable agents)
Acceptance criteria met: 0 pending, 31 blocked-with-rationale; undistributed count = 0 pending
No additional distribution needed — all undistributed improvements are documented orphans

2026-04-28 - Ninth dividend distribution batch (task:5a7fabd5)

Pre-run state: pending=0, distributed=729, orphan=31 — prior task (6311b5ac) already cleared backlog
Ran detect_improvements --limit 20 — detected 1 new improvement: citation_threshold=1
Ran backprop_credit --limit 10 — distributed 1 dividend: 200 tokens to 4 agent-credits (0 skipped)
Breakdown: citation_threshold_medium (200 tokens)
Post-run state: pending=0, distributed=730, orphan=31; discovery_dividend_payouts: 1233 rows, 57008 tokens total
