React/TypeScript frontend + Go backend enforcement harness. 92 wired hooks (101 scripts) enforce patterns on every edit. Green != done: `test-warning-check` + `ci-warning-audit` block passing tests with DeprecationWarning / React `act()` / unhandled rejection noise (local + `gh run view --log` on green CI). 71 skills from TDD through CI-green PR, including /diagnose feedback-loop-first 6-phase debugger + /triage multi-tracker (gh + acli) state machine + /steelman anti-sycophancy guard + /snyk-ux-security JS+Go per-path vuln sweep (exploitability-triage first gate via `bun why`/`go mod why`/`govulncheck`; top-level direct dep bump first, parent dep second, resolutions/overrides/replace last resort only; React 18 pin + changelog-walked majors + no-deferral escalation; Go `go get -u` + `go mod tidy` + `govulncheck` verify). 21 LLM failure modes enforced (7 Karpathy single-agent + 14 MAST multi-agent, Cemri et al. NeurIPS 2025). OWASP + STRIDE + snyk/bun audit. Core Web Vitals perf gate. bun.lock + yarn.lock parity enforced. Worktree isolation + branch safety. MCP ban with CLI redirect (~20x savings). Agent-browser integration (~91% token reduction). 9 agents (3-hat plan review + karpathy reference), 5 routines. Opus 4.7 tuned. POSIX-friendly.
