# AI build log

## 2026-09-22 · Preparation and official skill

- Goal: install the official Game Builder safely; read handbook first; create a playable, transaction-free desktop/mobile preparation build and submission draft.
- Agent/tools: Codex (GPT-6 family), PowerShell, Node, TypeScript, Three.js, Vite, browser automation and Playwright tests.
- Read first: https://hackathon.devfridge.cool/llms.txt and its linked https://hackathon.devfridge.cool/kit/handbook.md . Downloaded original handbook/submission/build-log/scorecard into `docs/official/`.
- Official bundle: https://world.devfridge.cool/world/skill/downloads/devfridge-game-builder.zip ; manifest: https://world.devfridge.cool/world/skill/downloads/manifest.json . Version 1.3.0, reviewed 2026-09-22, 26,678 bytes.
- SHA-256 verified: `90755b5f69ebb8d8f2e93a6bbc92400e00e3ad1ddcb80a4a5bfb1ea0a77b5f6c`. Each of 14 file hashes also verified.
- Archive reviewed before extraction, including SKILL.md, paths, types and file list. Extraction stripped its single expected root, rejected traversal/absolute paths/symlinks, checked final containment and preserved existing files. Destination did not already exist; no customized files replaced. All references/assets/agents files retained under `.agents/skills/devfridge-game-builder/` in the parent project.
- Loaded discovery, SDK, Phantom, delivery, visual, ecosystem, economics and program references. Ran official helper tests.

## 2026-09-22 · Discovery and policy

- User chose a cold-chain courier for a food/meme community and supplied mint `39kMeX4HVRW9qbbiHSPbRQ9xeXUF18GrNP6gL61Ppump`.
- User chose a timelock-unlocked challenge, then delegated exact access-rule selection with a price-related objective. Agent explicitly declined to promise price support and chose an accessible-sized pilot: 100 PASTA, original lock >=24h, remaining >=60s, sum same-mint/same-wallet vaults. No affordability/price conclusion was claimed from this arbitrary token quantity.
- Finalized RPC receipt at slot 449367314 confirms Token-2022, decimals=6, metadataPointer/tokenMetadata and initialized PASTA mint. Stored the response without private data. Current DevFridge documentation separately identifies this exact PASTA mint and direct-burn redemption treatment.
- No tokens bought; no funds moved; no messages/transactions signed; no contract deployed.

## 2026-09-22 · Implementation and verification

- Agent built an original procedural Three.js market and detailed courier, fixed-step game loop, keyboard/touch controls, pause/resume/result/replay, local unverified bests, Phantom detection/connection/cancellation, exact API gate, explicit fixture demonstration and pre-lock disclosures.
- Identity, eligibility and score authority remain distinct. No backend authentication or authoritative competition is claimed. The challenge UI uses real read-only API wiring; tests use mocked provider/evidence and are not evidence of successful mainnet wallet activity.
- Original gate helper kept unchanged. Added tests for complete simulated win/restart, timeout loss, movement bounds, heat cooldown, chosen policy/partial expiry, API coalescing/staleness/timeout/429 and fixture isolation.
- A certificate-trust issue interrupted the first package install. A clean `npm ci` with Node's system certificate store succeeded; TLS verification was not disabled. A transient UTF-8 file-writing issue was repaired before final build/tests.
- Browser integration testing caught an unbound native-fetch invocation in the read-only transport; changed the default fetcher to call globalThis.fetch and reran wallet acceptance/account-switch/rejection checks. Browser timing assertions now wait for visible state rather than assume software-WebGL frame timing. Removed unnecessary idle rendering and capped active drawing at 30 FPS.
- Human review so far: game/community, mint and delegated policy choices only. User has not yet reviewed art/gameplay, transactions or physical-device behavior.
- Browser evidence and final test outcomes: see `VERIFICATION.md`, `browser-test-results.json`, and screenshot files in this directory.
- Remaining: real phone/Phantom evidence, any server authority required by future features, public repository/HTTPS URL/demo video, final event eligibility once announced. No registration or submission has occurred.

## Source links and claim boundaries

- https://hackathon.devfridge.cool/kit/handbook.md (event status and integration requirements)
- https://docs.devfridge.cool/fridge (fee and exact PASTA mint, saved response in official/fridge-page.html)
- https://docs.phantom.com/solana/integrating-phantom (desktop/mobile injected provider)
- https://sdk.devfridge.cool (published integration; no invented npm SDK)
- https://api.mainnet-beta.solana.com (read-only finalized mint receipt)
- https://www.investor.gov/additional-resources/spotlight/crypto-assets (general risk context; no access policy can promise investment outcomes)

Event dates, prizes and submission window remain to be announced. Future completion/release must update this log and submission draft rather than treating outstanding evidence as passed.

## Publication preparation - 2026-09-22

User requested publication in the hackathon projects section. Public target: https://hackathon.devfridge.cool/projects/fridge-run/index.html . Source: https://github.com/mikeminer/devfridge/tree/master/games/fridge-run . Added an explicitly labelled project showcase and relative asset URLs. Earlier local-only statements describe the initial build. This follow-up prepares its public release; it is not an official hackathon submission.
