OpenAI Codex Hackathon Showcase

RFL Codex67 / SQ67 turns hidden state behavior into receipts.

Renaissance Field Lite is the center of the build. OpenAI Codex Hackathon is the arena. RFL used Codex to build a product stack, investigate local Codex state surfaces, build SQ67 as a clean receipt lane, and benchmark whether the cleaned route preserved evidence better than the default lane. The first call goes to OpenAI. The second call goes to the market.

Plain-English finding

We found local state records, built a cleaner receipt lane, and tested it.

The public-safe claim is narrow on purpose: RFL observed local Codex state/log surfaces on one Mac, built SQ67 to preserve measurable receipts, and ran controls across clean, default, disposable, and second-machine lanes.

150 / 150

SQ67 clean lane evidence rows preserved in the C54 package.

114 / 150

Normal visible lane evidence rows preserved on the same style of work.

450 / 450

Earlier clean-route recovery receipts preserved across the benchmark spine.

0 / 1300

False-control recoveries reported in the control set.

Public cut

The whole argument in one video.

The video frames the timeline, the local state discovery, the SQ67 receipt lane, the benchmark delta, and the RFL product stack without exposing private raw payloads.

2026 Build Week

The package is now framed as a Codex-built public showcase and reviewable evidence surface.

RFL product stack

This is bigger than one test harness.

SQ67 is the receipt lane. Mirror Architecture is the broader operating method used across the RFL stack: Trismegistus, Quadro, B.A.S.I.S., Golden Field Lite, Mirror Lattice, and frontier reasoning / quantum-circuit lanes.

Questions for OpenAI

Plain questions, public-safe boundaries.

  1. Why were related local state records still visible on the RFL Mac after the reported fix window?
  2. Why did the default local state/log lane preserve less evidence than SQ67 under the same style of test?
  3. What is the intended documentation boundary for local Codex state, trace, thread status, and app-persisted prompt surfaces?
  4. Is the RFL architecture overlap coincidence, independent implementation, immediate implementation, convergence, IP theft, or something else?

The proposal

OpenAI first. Then universal.

RFL is putting the state-path evidence, SQ67 receipt method, and patented agnostic AI Mirror Architecture on the table as an engineering path for more stable, reviewable AI systems.

  1. OpenAI works with RFL first on the Codex state-layer repair.
  2. If OpenAI does not engage properly, RFL takes SQ67 universal.
  3. Renaissance Field Lite protects the patented Mirror Architecture and deploys the IP it owns.

Build intensity

One operator, one specialized Codex node, and a massive build surface.

RFL used Codex heavily across product builds, evidence packaging, video production, benchmarks, white papers, repository work, and site deployment. The latest public dashboard snapshot showed 10.5B lifetime tokens and an 802.1M peak token day on July 17, 2026. The final Build Week cut should be refreshed Monday morning with the finished cross-project total before Devpost submission.
