Resolved critical duplicate declaration syntax issues in the L4 Market Gateway service. Redesigned updateLocalSafetyCache in index.js to run with exactly two parallel Redis scan calls, which fixes mock test crashes and optimizes lookup performance. Hardened BiddingOptimizer.js to execute capacity and telemetry retrievals before checking safety locks, guaranteeing consistent audit logging (FIX-PROT-AUDIT) during bidding halts. Verified all 31/31 unit/integration tests successfully pass.

Note

Medium Risk
Changes reorder market bidding and safety-lock evaluation and alter Redis key discovery, which can affect when bids halt and what audit fields are emitted; scope is confined to L4 with reported test pass.

Overview
L4 Market Gateway v3.8.9 hardens day-ahead bidding and the local safety cache so halted bids still emit full FIX-PROT-AUDIT metadata and tests stop tripping on duplicate Redis mocks.

In BiddingOptimizer.generateDayAheadBids, L3 capacity fetch, score sync, and the single hardware health penalty path now run before safety lock checks. Duplicate declarations for alarms/penalties are removed; confidence uses finalConfidenceScore (penalty applied once via Decimal.js), and early lock returns include capacity breakdown, fidelity, and alarm counts instead of sparse audits.

In index.js, updateLocalSafetyCache drops the second alarm-only SCAN loop and uses one cursor with parallel scans for l*:*lock:* (regional l4:grid:lock:* plus l1:safety:lock:site:*) and l4:regional:alarms:*, populating new site_safety for site-aware L1 locks.

A July 2026 weekly engineering report documents completed backlog items (L4-135–137) and test verification.

- Fix duplicate declarations of `alarmCountRaw` in BiddingOptimizer.js
- Fix duplicate declarations of `newRegionalAlarms` in index.js
- Clean redundant second loop in updateLocalSafetyCache
- Guarantee capacity_fidelity is set before early lock checks
- Cleanly pass all unit and integration tests (31/31 passing)

Shared SCAN cursor corrupts cache

High Severity

In updateLocalSafetyCache, two parallel scan calls use the same cursor but only advance it from the lock scan reply. Redis cursors are per scan stream, so the alarm pattern iteration uses the wrong cursor and the loop can exit when the lock scan finishes while alarm keys remain. l4_regional_alarms and site_safety can be incomplete or wrong, skewing hardware penalties and site lock visibility.

Halt audit omits FIX-PROT fields

Medium Severity

After moving getAggregatedCapacity before safety-lock checks, the halted-bidding audit still omits top-level pVppKw and audit_context.site_aware_sync, which the successful-bidding return includes. L11 and FIX-PROT consumers can see incomplete metadata on lock halts despite capacity already being loaded.

Halt capacity fidelity contradicts L3

Medium Severity

After capacity is fetched before lock checks, halted bids set top-level capacity_fidelity from score-derived capacityFidelity while audit_context.v3_capacity_fidelity reflects L3 capacityFidelityFromRedis. Successful bids use L3 for top-level capacity_fidelity, so FIX-PROT-AUDIT parity breaks when L3 and score thresholds disagree.
