📊 Time Summary

March 2026

Sprint 15 delivered the BOINC-inspired distributed compute grid, a full service architecture migration to *.api=/=*.core layers, a production-grade JWT refresh system, and four new CDM instrument domain models.

✅ Highlights

Distributed compute grid — full stack implementation (domain, SQL, service, wrapper, NATS JetStream, Qt UI) inspired by BOINC, with telemetry pipeline and RAG service health dashboard.
Service architecture migration — all ten service libraries (iam, refdata, compute, scheduler, assets, variability, synthetic, trading, reporting, http.server) split into *.api (contracts) and *.core (implementation) layers.
JWT token refresh — configurable lifetimes via system settings, iam.v1.auth.refresh endpoint, reactive shell retry, proactive Qt timer, and ores_iam_auth_events_tbl TimescaleDB telemetry hypertable.
CDM instrument models — Rates (Swap, CrossCurrencySwap, CapFloor, Swaption), FX (FxForward, FxSwap, FxOption), Bond (Bond, ForwardBond, CallableBond, ConvertibleBond, BondRepo), and Credit (CDS, CDSIndex, SyntheticCDO).
Unified system settings — replaced ores_variability_feature_flags_tbl with ores_variability_system_settings_tbl supporting bool, int, string, and JSON value types across all stack layers.

🛠️ Key Improvements

Compute Grid

BOINC-inspired grid with ores.compute.service and ores.compute.wrapper executables; NATS JetStream lifecycle transitions replace legacy PGMQ/pg_cron.
Telemetry: ores_compute_grid_samples_tbl and ores_compute_node_samples_tbl hypertables; get_grid_stats unified NATS endpoint for dashboard.
E2E fixes: result-stuck-InProgress bug, host_id persistence, outcome code mapping, SIGSEGV on window close, file extension preservation in artifact URIs.
Loading lifecycle refactored via AbstractClientModel with dataLoaded()=/=loadError() signals wired to endLoading() across all six compute MdiWindows.

Authentication & Security

Token lifetimes configurable via iam.token.* system settings; hot-reloaded on system_setting_changed events.
make_request_context() now explicitly returns token_expired / unauthorized error codes via X-Error NATS headers — updated across all 48 domain handlers.
Auth telemetry records login, logout, refresh, max-session events with 90-day/3-year retention policies.

Architecture

All modules migrated to *.api / *.core three-layer pattern; HTTP route handlers relocated to domain core modules.
NATS service discovery: Qt client auto-discovers HTTP base URL after login via ores.http shared protocol types — eliminates manual http_port config.
Full PostgreSQL environment isolation: environment-prefixed roles prevent cross-environment contamination.

Infrastructure & DX

sccache CI bloat fixed: cross-PR cache sharing, increased sccache limit — reduced cold build times from 2+ hours.
ORES_PRESET stored in .env; new start-client.sh supports multi-instance coloured Qt clients.
Loading indicators (4px indeterminate progress bar) added to all 45+ entity list windows.
Badge system Phase 1 infrastructure: badge_definition and badge_mapping domain entities with DB-driven metadata for reuse across Qt and Wt.

⚠️ Known Issues & Postponed

CDM CLI commands (instruments list/add/delete) deferred to a follow-up story for all four instrument phases.
Database recreate required to pick up new ores_trading_fx_instruments_tbl, ores_trading_bond_instruments_tbl, ores_trading_credit_instruments_tbl tables.
Three-level provisioning (party wizard split, provision-parties endpoint, ores.workflow orchestration service) — Phase 1 landed late in sprint; Phases 2–3 deferred to Sprint 16.
