Fig.01 @ 92d444f — Monolith / S3 website

Fig.01 at 92d444f: EC2 with a local IB Gateway, Alpaca historical bars, trading.db, cron generate.py, and an S3 website dashboard.

2026-04-17 14:08 +0800 · Add SQLite persistence + S3 static dashboard

Public host: S3 website, account 376791751748. EC2 runs a local IB Gateway, Alpaca historical bars, and trading.db. Cron runs generate.py and publishes the Jinja dashboard to the S3 website.

Fig.02 @ a42ae99 — Dual-EC2 + Lambda render

Fig.02 at a42ae99: EventBridge and quant-ec2-scheduler around gateway-02, live engine on quant-ec2-live-01, Phase 6 Lambda render with schedules disabled, and an S3 website.

2026-05-13 19:18 +0800 · feat(dashboard): Phase 6 - Lambda render with S3 inputs (#280)

Public host: S3 website. EventBridge drives quant-ec2-scheduler, which starts and stops gateway-02. The live engine runs on quant-ec2-live-01. Phase 6 Lambda render, schedules disabled, reads sync inputs; a Jinja publisher writes the S3 website.

Fig.03 @ eafff22 — Massive + Astryx + CloudFront

Fig.03 at eafff22: Massive market data, signed Astryx React on channels/live, CloudFront d3f4e9lehnan57, GitHub Actions stage, and gateway-02 with the IBKR path.

2026-07-24 07:06 +0800 · feat(dashboard): ship immutable Astryx dashboard pipeline (#342)

Public host: CloudFront d3f4e9lehnan57.cloudfront.net. Massive market data and a signed Astryx React build on channels/live sit behind that distribution. GitHub Actions stages the dashboard. Gateway-02 carries the IBKR path into trading.db. Lambda render schedules are disabled.

Fig.04 @ c01b8f0 — Rebuild / OAC

Fig.04 at c01b8f0: account 890968193131 with Alpaca REST, a local scanner, live-01 running 24×7, EventBridge render enabled, and CloudFront d2c9pzwpavuktk with origin access control.

2026-09-23 23:44 +0800 · chore: remove the dead IB Gateway path end to end (#387)

Public host: CloudFront d2c9pzwpavuktk.cloudfront.net, account 890968193131. Alpaca REST and a local scanner run on live-01, 24×7. EventBridge render schedules are enabled. Origin access control fronts separate dashboard and assets buckets. The S3 dashboard is the gold source of truth.

Fig.05 @ be85f71 — Classic CloudFront + EC2 sleeper

Fig.05 at be85f71: EC2 sleeper, React publisher, CloudFront d2c9pzwpavuktk as the public entry, side Workers open-ledger, ledger-mcp, and metrics, plus the replay CLI.

2026-10-10 20:16 +0800 · Dashboard summary: additive replay_attribution block (#478)

Public host: CloudFront d2c9pzwpavuktk.cloudfront.net. An EC2 sleeper runs between sessions. The publisher is React. Side Workers — open-ledger, ledger-mcp, and metrics — and the replay CLI sit beside the stack.

Fig.06 @ cfa3bc9 — Oakrelay Worker proxy

Fig.06 at cfa3bc9: Oakrelay Worker quant.oakrelay.dpdns.org proxying classic CloudFront d2c9pzwpavuktk, with the EC2 sleeper, React publisher, side Workers, and replay CLI.

2026-10-11 17:00 +0800 · ops: publish warehouse fills to open-ledger via GitHub Actions · current

Public hosts: Worker proxy quant.oakrelay.dpdns.org and classic CloudFront d2c9pzwpavuktk.cloudfront.net. The sleeper, React publisher, side Workers, and replay CLI are in the stack with them. The S3 dashboard is the gold source of truth. The proxy host is ops-captured.
