Opencode pattern (session/overflow.ts): fire compaction at 85% of ctx_max, replacing the v1.11.0-era `ctx_max - 20_000` formula. Old formula: usable = ctx_max - 20_000 - ctx=262144 → trigger at 242144 (92.4%) — only 7.6% headroom - ctx=100000 → trigger at 80000 (80.0%) - ctx= 32000 → trigger at 12000 (37.5%) — over-eager - ctx<=20000 → trigger at 0 — never fires New formula: usable = floor(0.85 * ctx_max) - ctx=262144 → trigger at 222822 (85.0%) — 15% headroom for summarizer - ctx=100000 → trigger at 85000 (85.0%) - ctx= 32000 → trigger at 27200 (85.0%) - ctx= 8192 → trigger at 6963 (85.0%) Ratio gives consistent headroom at any context scale. The qwen3.6 daily driver gets ~19k tokens more breathing room before overflow; small-ctx models no longer degenerate to never-triggering. usable() is the only consumer of COMPACTION_BUFFER → constant deleted. New EARLY_TRIGGER_RATIO constant takes its place. isOverflow() and the maybeFlagForCompaction() call site at payload.ts:184 are unchanged — formula swap is internal to compaction.ts. payload.ts comment touched only to drop the stale COMPACTION_BUFFER reference (PRUNE_TRIGGER_TOKENS stays at 20k as the prune-freed threshold; independent of the overflow formula). Tests: 4 new usable() corner cases (262k/100k/8k/zero+negative), plus 5 isOverflow() numbers shifted to match the 85k budget at ctx=100k. 195/195 server tests pass (was 194). Smoke: ratio math verified by unit tests at all four corners. Live cap-hit verification deferred — requires accumulating >222k tokens in a session under qwen3.6-35b-a3b-mxfp4 (was >242k pre-fix); will surface organically in extended use.
boocode
Self-hosted single-user developer chat app. v1: chat only.
Stack
- Node 20, Fastify, postgres (porsager/postgres), ws, zod
- React 18, Vite, TypeScript, Tailwind v4, shadcn/ui
- Postgres 16
- pnpm workspaces
Layout
apps/server— Fastify API + WebSocket + inference loop + file-read toolsapps/web— React frontend; served by Fastify in production, Vite in dev
Local dev
Requires Node 20, pnpm, Docker (for Postgres), and ripgrep.
# install
pnpm install
# bring up postgres only
cp .env.example .env
# edit POSTGRES_PASSWORD if you like; default DATABASE_URL points at the container
docker compose up -d boocode_db
# run server (port 3000) and web (port 5173) in two shells

LLAMA_SWAP_URL=http://100.101.41.16:8401 \
pnpm dev:server
pnpm dev:web
The Vite dev server proxies /api and /api/ws/* to the Fastify backend with a
synthetic Remote-User: sam header so the Authelia auth layer can be skipped
during development.
Production
cd /opt/boocode
docker compose up --build -d
Binds to 100.114.205.53:9500 (Tailscale). Authelia is expected to gate the
upstream and inject Remote-User. Postgres binds loopback only.
What v1 has
Project sidebar, sessions per project, chat with streaming responses over
WebSocket, four file-read tools scoped to the project root (view_file,
list_dir, grep, find_files), and a model picker driven by llama-swap's
/v1/models.
What v1 does not have lives in v2 (terminal pane) and v3 (Coder pane).
