Ki Clash

2026년 6월 10일 · 4 분

Added a k6 load/perf suite (smoke, ramping REST, and concurrent WebSocket capacity scripts) against the live JJAN backend, plus a GitHub Actions CI pipeline whose python/go/web jobs gate every push and PR to main — the test gate the Vercel auto-deploy flow was missing.

Go-live on AWS EC2 (t3.micro) exposed bugs no local run had: a single-player 'Game not found' from 2 uvicorn workers over in-memory state, a broken disconnect/reconnect + forfeit-stats + /health HEAD path, a pubsub listener that crashed on idle, and OOM during builds — fixed with --workers 1, a session repair, get_message polling, and 2GB swap baked into user_data.

Locks every gameplay phase to one no-scroll viewport (100svh, capped arena, compact spacing) on a single stable skeleton that never reflows, removes the growing in-match turn history, makes the web client an installable home-screen PWA, and cuts the AI reveal/round hold from 5.1s/4.5s to 3s.

A PixiJS v8 WebGL effect engine and /pixi-test harness wired into both PvP and vs-AI matches — plus the day's hard lesson: the first integration replaced the dynamic KiAuraArena and silently deleted its character motion, so it was reverted and re-done as an additive transparent overlay (DR-18: enhance = compose, not replace).

One Terraform module stands up the JJAN! backend on AWS — a /16 VPC, a single t3.micro EC2 host, a lifecycle-protected EBS data volume that outlives instance replacement, and an Elastic IP — followed by four deploy fixes the first real build surfaced (Go base bump, distroless self-healthcheck, Caddy domain, Vercel build env).

Gated turn 1 behind a two-player presence check so the 5s turn clock never starts against a ghost opponent, split the room start-guard from the handoff-guard to fix a 'Match starting' hang, made CharacterAvatar render the real fighter PNG, then ran an 8-dimension live verification that surfaced 4 bugs.

Added a root-level vercel.json so Vercel builds the web/ subdirectory in this monorepo instead of failing on a missing root package.json, then layered 301 redirects so www and the old kiclash alias both funnel to the canonical jjan.daeseon.ai.

Renamed the user-visible product from "Ki Clash" to "JJAN! · 짠" across the web surfaces (metadata, lobby, shop, share-sheet) while keeping the internal ki-clash code slug untouched, and shipped a grounded bilingual EN/KO recruiter README plus a problem-indexed troubleshooting reference.

Replaced the one generic match-end beam with six per-character signature ultimates, swapped the emoji placeholders on character-select for the real fighter PNGs under global-friendly names, and closed the 6×6 fighter sprite matrix with seokjin + yuri's pose sets.

Phase 11 rebuilds all six arena effects in-house with framer-motion + canvas-confetti + multi-layer SVG (zero external dependency), fixes white-box fighter backgrounds with local AI bg removal + pose-aware sprite transforms, and splits the Attack (POW punch) and Energy Wave (energy-beam) moves into visually disjoint FX.

Deploy-night checkpoint: Phases 1-4, 7, 8, and 10 are done and the backend is production-ready; Phase 9 (the actual AWS EC2 + Vercel deploy) is the only outstanding work and is waiting on Jason — nothing is live yet.

2026년 6월 1일 · 1 분

Phases 7D-F replaced placeholder fighters with humanoid then shōnen-knockoff sprites, added hit/KO reactions and a match-end final-blow KO sequence, and moved to an image-first pipeline backed by 6 AI-generated idle sprites.

Three commits stood up the Go game-server tier from DR-1's hybrid 2-tier design: a WebSocket scaffold, a full game-loop port wired for prod, and a hardening pass adding cross-instance reconnect, metrics, Sentry, unit tests, and a load harness.

2026년 6월 1일 · 2 분

Phase 7 ships a cinematic match-end finale and an anime ki-aura arena in the web client, realizing decision DR-2's move from pixel art to a high-impact arcade anime aesthetic.

2026년 6월 1일 · 1 분

Phase 8 adds Tekken-style room PvP — create a room code, share it, pick a character, and ready up — with a backend rooms API plus the frontend /pvp flow, followed by a chore to auto-derive the WebSocket URL from the API URL in production.

2026년 5월 28일 · 1 분

Added a Part 0 'RESUME HERE' checkpoint to docs/engineering-log.md so the next session opens with a single where-are-we / what's-next handoff snapshot.

2026년 5월 27일 · 2 분

Scaffolded the production deployment stack as an AWS EC2 + Vercel hybrid — a single docker-compose stack (db + redis + api + caddy) on EC2 with Caddy terminating TLS and reverse-proxying the FastAPI backend, and the Next.js frontend on Vercel.

2026년 5월 26일 · 2 분

Added a 'Part 2 — Engineering Decision Reference' section to docs/engineering-log.md with 11 deep trade-off analyses (DR-1..DR-11), each documenting the decision, options, trade-off table, reasoning chain, meta-pattern, and interview framing.

Created a standalone Korean networking reference doc that maps Ki Clash code onto real-time multiplayer concepts, doubling as Toronto game/systems interview prep.

Phase 2 added 52 new tests (game engine, matchmaking) and the observability backbone — structured JSON logging, Sentry, and Prometheus /metrics — plus a client-side JWT 401 auto-recovery fix. Suite grew from 52 to 99 tests.

Phase 3 fixed the 4 PvP concurrency bugs documented as xfail during Phase 2.1; the integration suite went from 6 passed / 4 xfailed to 10 passed, and the full suite to 126 passed.

2026년 5월 26일 · 4 분

Phase 4 externalized all in-memory PvP state to Redis, added per-player pub/sub for cross-worker routing, and used optimistic concurrency for atomic two-player turns — landing the full suite at 149 tests passing in ~23s.

2026년 5월 26일 · 3 분

Driving a real Bo3 match through a PvP simulator against the live docker stack surfaced 4 concurrency/protocol bugs, which were then locked into a permanent pytest integration harness as xfail tests.

Scaffolded a drop-in asset pipeline with graceful emoji fallback components on web and mobile, and moved the pixel-art code into a deprecated/ folder via git mv since 12+ active screens still import it.

2026년 5월 24일 · 3 분

A strategy/planning session (no code commit) that re-grounded the Ki Clash spec, locked a 2-tier Python-now/Go-later backend, and pivoted the visuals from pixel art to a modern anime card-game aesthetic with AI-generated assets.

2026년 2월 23일 · 2 분

First-deploy night on Railway — added a Dockerfile and railway.toml with auto-migration, fixed dynamic PORT binding and Dockerfile COPY order, and shipped the dramatic match-finish energy-wave beam.

Added a roster of 6 original Korean fighters with a dedicated character select screen, converted the countdown into a selection timer, layered in AI trash talk and an interactive tutorial, and ported the whole set to mobile.

Single milestone commit shipped the product-agnostic game engine, an AI opponent with difficulty tiers, a versioned FastAPI backend, and a Next.js web frontend — plus dev-workflow slash commands.

A game-feel pass on the web client: a 3-beat countdown between action confirm and reveal, procedural Web Audio sound effects with a mute toggle, a card-flip reveal with screen shake on outcomes, and an animated AI thinking indicator.

2026년 2월 22일 · 2 분

Built a dedicated pixel-art rendering layer plus per-fighter frame data for 6 fighters, wired it into the live web game UI, and ported the whole system to the React Native mobile client.

2026년 2월 22일 · 1 분

Built the realtime PvP backbone for Ki Clash: a room-based WebSocket manager, a Redis-backed FIFO matchmaking service, and a WebSocket-driven game session, plus a PvP frontend with matchmaking and game UI.

2026년 2월 22일 · 1 분

Scaffolded a React Native (Expo) mobile app with TypeScript and expo-router, then built the full game UI, AI/PvP flow, and ported the web 'game feel' features to native.

The repo is born with an initial README naming it Product003_KiDuelGame, followed by a CLAUDE.md founding philosophy that codifies Jason's core beliefs and build methodology.
