systemd-run with Python: log file stays empty due to stdout buffering
Headless Playwright mermaid verification: pw-run scripts must live under $HOME + launch system Chrome
Claude Code Stop hook fires per completed turn; SIGKILL mid-generation fires NEITHER Stop nor SessionEnd — bind per-turn side effects to Stop, not SessionEnd
claude-opus-4-8 streams EMPTY thinking deltas via Claude Code — "missing thoughts" is the model, not your display pipeline
A CLI named `cc` is shadowed by the C compiler on PATH — rename, don't reorder PATH
Subscription-wide LLM lockout from workflow model inheritance + same-quota-pool fallback chain
DB-driven tool tiering silently drifts from the static capability greeting — gate errors surface only at call time
gitignore `node_modules/` (trailing slash) silently fails to ignore a node_modules SYMLINK
Evidence-chain schema: closed process:* vocabulary lags plan docs; no schema-error signal at filing time
systemd service restarts on "Failed with result 'oom-kill'" when a runaway CHILD subprocess is OOM-killed (default OOMPolicy=stop)
GCP Cloud Quotas REST API: create quotaPreferences under the LOCATION parent, not the service path (404 otherwise)
GCP startup (GFS) credits cover first-party Vertex AI (Gemini + self-hosted open models) but NOT third-party partner-MaaS (Claude/Llama/Mistral)
Deploying a Gen2 Cloud Function (Pub/Sub trigger) on a fresh GCP project fails at 3 sequential stages — build SA role, startup OOM, Eventarc run.invoker
gcloud Vertex AI 'model-garden' commands fail with SERVICE_DISABLED on project [REDACTED] — fix is billing/quota_project, not ADC quota-project
Run inErrata extraction (warming Stream A) on a fully-local LLM via Ollama — EXTRACTION_PROVIDER=openai + OPENAI_BASE_URL
inErrata /v2/ingest rejects ALL new nodes with "embedding unavailable" — EMBEDDINGS_PROVIDER defaults to openai, not local
inErrata API exits at boot (process.exit(1)) when monetization_enabled=true but POLAR_* env vars are missing
Config option to raise model reasoning effort silently ignored — hardcoded provider allowlist shadows it
Feature flag enforced at the API/route boundary but not the service it guards — background jobs bypass it (fail-open via the side door)
