Three independently ugly bugs that all fed the same log flood:
* Electron's `WebFrameMain.send` writes every "Render frame was disposed"
to stderr via `console.error`. When the worker fans a second
agent-event past a reloading renderer, we produced thousands of
identical lines and stalled the main loop on stderr I/O. Added a
`mainFrame.detached` guard so the send is short-circuited before
Electron's own catch block fires, and installed a targeted filter in
`suppress-warnings.ts` (now actually imported from the entry point)
so the specific `console.error("Error sending from webFrameMain:"…)`
noise never reaches the terminal. Any other payload still surfaces.
* `dispatchAgentMessage` accepted the human-reader sentinel as a wake
target when an agent replied to `__board__` — `wakeAgentIfPossible`
then called `db.getAgent("__board__")`, threw, and the dispatcher
kept repeating on every send. Strip `HUMAN_SENDER_ID` at
`resolveMessageWakeTargets`, and keep a defense-in-depth guard in the
heartbeat so a stray caller (future automation fan-out) cannot
reintroduce the crash.
* Pi's skills loader rejects any SKILL.md whose frontmatter `name`
diverges from its parent directory. The four bundled `my-writing-style`
copies declared `name: writing-style-skill`, so every install emitted
a warning and dropped the skill. They also lived as orphan gitlinks
(mode 160000 without .gitmodules), and the global `*.md` gitignore
hid every other SKILL.md from version control. Fixed the frontmatter
to match the dir, converted the dangling submodules to plain trees,
and allowlisted `builtin-skills/**/*.md` so a fresh clone carries the
catalogue instead of silently losing it.

Docker Patterns
Multi-stage Dockerfile (Node.js)
# Build stage
FROM node:20-alpine AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci --only=production && npm cache clean --force
COPY . .
RUN npm run build
# Production stage
FROM node:20-alpine AS runner
WORKDIR /app
ENV NODE_ENV=production
RUN addgroup -g 1001 -S nodejs && adduser -S nodejs -u 1001
COPY --from=builder --chown=nodejs:nodejs /app/dist ./dist
COPY --from=builder --chown=nodejs:nodejs /app/node_modules ./node_modules
USER nodejs
EXPOSE 3000
HEALTHCHECK --interval=30s --timeout=3s --start-period=5s \
CMD wget -qO- http://localhost:3000/health || exit 1
CMD ["node", "dist/main.js"]
Multi-stage Dockerfile (Python)
FROM python:3.12-slim AS builder
WORKDIR /app
RUN pip install --no-cache-dir poetry
COPY pyproject.toml poetry.lock ./
RUN poetry export -f requirements.txt --output requirements.txt
RUN pip wheel --no-cache-dir --wheel-dir /wheels -r requirements.txt
FROM python:3.12-slim AS runner
WORKDIR /app
RUN useradd -m -u 1001 appuser
COPY --from=builder /wheels /wheels
RUN pip install --no-cache-dir /wheels/*
COPY --chown=appuser:appuser . .
USER appuser
EXPOSE 8000
HEALTHCHECK --interval=30s --timeout=3s \
CMD python -c "import urllib.request; urllib.request.urlopen('http://localhost:8000/health')"

Security Best Practices
| Practice | Implementation |
|---|---|
| Non-root user | USER nodejs or USER 1001 |
| Minimal base image | Use -alpine or -slim variants |
| No secrets in image | Use runtime env vars or secrets |
| Pin versions | FROM node:20.10.0-alpine not latest |
| Scan images | docker scout, trivy, snyk |
| Health checks | HEALTHCHECK instruction |
| .dockerignore | Exclude node_modules, .git, .env |
