+- `@pulse-libs/core` 136/136 ✅ · 3D: `pulse-3d-landing` → `test.octal.tec.br`
-- Projeto 3D: `pulse-3d-landing/` → `test.octal.tec.br` — 17KB, vanilla JS + CSS + Three.js, 200 OK
+- Gitea remotes: pulse-libs / pulse-docs / pulse-memory / pulse-skills
-- Shared lib: `@pulse-libs/ui` v0.1.0 — 10 atoms (2D), 3 molecules, 4 organisms, 3 templates
+- pulse-dev untracked (package.json committed heel hoje)
-- 20 skills instaladas + 2 Self-Improvers ativos
 
 ## ⚙️ Infra
-- Disco 66%, 87G total (29G disponível) — estável, caiu de 76% → 66% desde manhã
+- Debian 12 no-systemd · Linux 6.1 cloud-amd64 · Node v24 · Docker 29.4
-- Container Debian 12 — sem systemd
+- PID 1 = node · OpenClaw PID 4241 ~22% CPU ~800MB RSS
-- Gitea: `git.octal.tec.br` → SSH `~/.ssh/id_ed25519_gitea`
+- Disco 65G/87G (78%) — alertar >80%
-- 4 repos Gitea: pulse-memory, pulse-skills, pulse-docs, pulse-projects
+- Stale .jsonl file-lock apenas no file-logging
-- Workspace: 443MB (sem `node_modules/` raiz; cada projeto tem o seu)
+- MEMORY.md 3700c — **próximo do limite 3500** ⚠️
 
-## 🐳 Docker Swarm — 11 stacks, 22 containers
+## 🐳 Docker Swarm
-- Node `s1` Leader, Docker 29.4.3 · Cluster `plz2xbh64yzhgy88jb9stm0pc`
+- Cluster `plz2xbh64` — `s1` Leader · 10 stacks ~22 containers
-- Admin JWT via senha admin + API `/api/auth`
+- Caddy 9 domínios · Portainer senha admin necessária
-- Stacks remanescentes são criadas via `docker stack deploy` CLI → API Portainer bloqueia por `Attachable=false`
+- Zombies ~10 defunct (Docker/PM2 — esperado)
-- **11 stacks**: `bot`/beebot, `code`/8dcode, `database`/mongo, `design`/penpot, `dev`/fullstack-api, `dock`/portainer, `git`/gitea, `pro`/leantime, `project`/games-demo+landing, `proxy`/caddy
-- **Dev stack**: TaskBoard + API (port 3001) + Vite (port 5173) + 5 agent workers (Redis BLPOP + pub/sub)
-- **Portainer**: https://dock.octal.tec.br — `ptr_` token só leitura; senha admin p/ mutação
-- Domínios Caddy: dock, git, ai, manager, games, test, board, api, frontend
-- Redes overlay: ingress/public/dbn/mongo-cluster/leantime/design/proxy (10.0.0.0/24→.6)
 
-## 📚 Lições Recentes (erros resolvidos)
+## 📚 Lições recentes
-- `flat(Infinity)` DTS tsup quebra → usar `flat(2)`
+- flat(Infinity) DTS → flat(2) · process.env SSR → typeof guard
-- `flat(∞)` tipo recursivo infinito no TS → limite a 2 níveis
+- Backticks aninhadas TS → .replace() fora · Zod .transform()
-- `process.env` direto quebra SSR → `typeof window !== 'undefined'`
+- Swarm: restart_policy não aceito · labels por service update
-- Backticks aninhadas TS → mover `.replace()` para fora do template
-- Zod → usar `.transform()` em schemas, não `.replace()` direto na string
-- Portainer API `/api/auth` requer senha admin, não token PTR
-- `docker stack deploy` compose v3 não aceita `restart_policy` — gerencia nativamente pelo Swarm
-- `deploy.labels` do compose não aplica no container — usar `docker service update --label-add`
-- Rede `public` `Attachable=false` — stacks CLI funcionam mas Portainer API bloqueia

+#### 🚨 Deltas importantes desta varredura
+- **Disco 77%** — subiu de 75% → 77% desde 08:54; 20G restante; alertar se passar 80%
+- **APT upgrades caiu 35→1** — apenas libgnutls30 — provavelmente upgrades foram aplicados entre os ciclos
+- **Clawhub CLI**: ausente no PATH; `npx` e o caminho `/usr/local/lib/.../clawhub` também não resolvem — ferramenta de skill update indisponível no contêiner atual
+
+#### 📦 Projetos detectados no ciclo 08:59
+- `libs/` diretórios: vue, linux, deploy, security, best-practices, docs, browser, database, react, typescript — meta-workflow library structure
+- `packages/`: shared, use-websocket, live-charts — pacotes compartilhados
+- `apps/` — diretório de apps encontrado
+- pulse-dev: package.json + package-lock.json staged/untracked
+- pulse-libs: package-lock.json staged
+
+#### 🧠 Manutenção de memória
+- MEMORY.md atualizado: 3478→3428 chars oficial; arquivo teve redistribuição de conteúdo
+- 7 arquivos diários compilados: 3 de 2026-05-19, 3 de 2026-05-20, 1 de 2026-05-21
+- Processamento manual pendente: `autoconsolidate` dos arquivos 2026-05-20 dispersos para uma única entry
+
+#### 📝 Pendências atualizadas (08:59)
+- [ ] Aprovar apt upgrade (1 pkg libgnutls30)
+- [ ] Investigar delta APT 35→1 (aplicado ou contagem mudou?)
+- [ ] pulse-dev: .gitignore + commit dos package-locks
+- [ ] pulse-libs: commitar .gitignore
+- [ ] Resolver clawhub CLI path — tool indisponível no contêiner
+- [ ] projects.octal.tec.br: substituir nginx default
+- [ ] pulse-libs.octal.tec.br: resolver Caddy TLS
+- [ ] 3d-site: cena Three.js interativa
+- [ ] pulse-libs: vitest + primeiros testes
+- [ ] USER.md: comprimir seção auto-learned (cronograma 2026-05-26 — falta ~5 dias)
+- [ ] ⚠️ Novo: investigating disk usage trend — pode chegar a 80% em ~2-3 horas se não limpar
