+description: Use the Crabbox wrapper for OpenClaw remote validation across Linux, macOS, Windows, and WSL2, including delegated Blacksmith Testbox proof. Report the actual provider and id.
+---
+
+# Crabbox
+
+Use the Crabbox wrapper when OpenClaw needs remote Linux proof for broad tests,
+CI-parity checks, secrets, hosted services, Docker/E2E/package lanes, warmed
+reusable boxes, sync timing, logs/results, cache inspection, or lease cleanup.
+
+Crabbox is the transport/orchestration surface. The actual backend can be:
+
+- brokered AWS Crabbox: direct provider, `provider=aws`, lease ids like
+  `cbx_...`, `syncDelegated=false`
+- Blacksmith Testbox through Crabbox: delegated provider,
+  `provider=blacksmith-testbox`, ids like `tbx_...`, `syncDelegated=true`
+
+For OpenClaw maintainer broad `pnpm` gates, Blacksmith Testbox through the
+Crabbox wrapper is acceptable and often preferred when the standing Testbox
+rules apply. Do not describe those runs as "AWS Crabbox"; report them as
+Testbox-through-Crabbox with the `tbx_...` id and Actions run.
+
+Use the repo `.crabbox.yaml` brokered AWS path when the task specifically needs
+direct AWS Crabbox behavior, persistent direct-provider leases, `--fresh-pr`,
+`--full-resync`, environment forwarding, capture/download support, or provider
+comparison. Use `--provider blacksmith-testbox` when the task needs OpenClaw
+maintainer Testbox proof, prepared CI environment, broad/heavy pnpm gates, or
+the user asks for Testbox/Blacksmith.
+
+## First Checks
+
+- Run from the repo root. Crabbox sync mirrors the current checkout.
+- Check the wrapper and providers before remote work:
+
+```sh
+command -v crabbox
+../crabbox/bin/crabbox --version
+pnpm crabbox:run -- --help | sed -n '1,120p'
+../crabbox/bin/crabbox desktop launch --help
+../crabbox/bin/crabbox webvnc --help
+```
+
+- OpenClaw scripts prefer `../crabbox/bin/crabbox` when present. The user PATH
+  shim can be stale.
+- Check `.crabbox.yaml` for direct-provider defaults. Omitting `--provider`
+  means brokered AWS today.
+- The brokered AWS default is a Linux developer image in `eu-west-1`; the repo
+  config pins hot `eu-west-1a/b/c` placement so Fast Snapshot Restore can apply.
+  If warmup drifts well past the minute-scale path, verify image promotion,
+  region/AZ placement, and FSR state before blaming OpenClaw.
+- For broad OpenClaw maintainer `pnpm` gates, prefer the repo wrapper with
+  `--provider blacksmith-testbox` or the repo Testbox helpers when the standing
+  Testbox policy applies.
+- Always report the actual provider and id. `cbx_...` means AWS Crabbox;
+  `tbx_...` means Blacksmith Testbox through Crabbox. If the output only says
+  `blacksmith testbox list`, use `blacksmith testbox list --all` before
+  concluding no box exists.
+- If a warm direct-provider lease smells stale, retry with `--full-resync`
+  (alias `--fresh-sync`) before replacing the lease. This resets the remote
+  workdir, skips the fingerprint fast path, reseeds Git when possible, and
+  uploads the checkout from scratch.
+- For live/provider bugs, use the configured secret workflow before downgrading
+  to mocks. Copy only the exact needed key into the remote process environment
+  for that one command. Do not print it, do not sync it as a repo file, and do
+  not leave it in remote shell history or logs. If no secret-safe injection path
+  is available, say true live provider auth is blocked instead of silently using
+  a fake key.
+- Prefer local targeted tests for tight edit loops. Broad gates belong remote.
+- Do not treat inherited shell env as operator intent. In particular,
+  `OPENCLAW_LOCAL_CHECK_MODE=throttled` from the local shell is not permission
+  to move broad `pnpm check:changed`, `pnpm test:changed`, full `pnpm test`, or
+  lint/typecheck fan-out onto the laptop.
+- Only use `OPENCLAW_LOCAL_CHECK_MODE=throttled|full` when the user explicitly
+  asks for local proof in the current task. If Testbox is queued or capacity is
+  constrained, report the blocker and keep only targeted local edit-loop checks
+  running.
+
+## macOS And Windows Targets
+
+Use these only when the task needs an existing non-Linux host. OpenClaw broad
+Linux validation uses the repo Crabbox config unless a provider is explicitly
+requested.
+
+Native brokered Windows is available for Windows-specific proof. Use the AWS
+developer image in `us-west-2` on demand; it has the expected OpenClaw developer
+toolchain and Docker image cache. Keep broad Linux gates on Linux/Testbox unless
+the bug is Windows-specific:
+
+```sh
+../crabbox/bin/crabbox warmup \
+  --provider aws \
+  --target windows \
+  --windows-mode normal \
+  --region us-west-2 \
+  --market on-demand \
+  --timing-json
+```
+
+The hydrate workflow assumes Docker should already be baked into Linux images
+and only installs it as a fallback. Do not add per-run Docker installs to proof
+commands unless the image probe shows Docker is actually missing.
+
+When the user explicitly asks for brokered macOS runners, use Crabbox AWS
+macOS only after confirming the deployed coordinator supports EC2 Mac host
+lifecycle/image routes and the operator has AWS EC2 Mac Dedicated Host quota
+and IAM. Prefer `CRABBOX_HOST_ID` for a known Crabbox-managed Dedicated Host,
+or run the no-spend preflight first:
+
+```sh
+crabbox admin hosts quota --provider aws --target macos --region eu-west-1 --type mac2.metal --json
+crabbox admin hosts allocate --provider aws --target macos --region eu-west-1 --type mac2.metal --dry-run --json
+CRABBOX_MACOS_TYPES=all scripts/macos-host-region-preflight.sh
+```
+
+Do not silently substitute AWS macOS for normal OpenClaw Linux proof. Report
+paid-host blockers as quota, IAM, coordinator deployment, or host availability
+instead of falling back to local macOS.
+
+Crabbox supports static SSH targets:
+
+```sh
+../crabbox/bin/crabbox run --provider ssh --target macos --static-host mac-studio.local -- xcodebuild test
+../crabbox/bin/crabbox run --provider ssh --target windows --windows-mode normal --static-host win-dev.local -- pwsh -NoProfile -Command "dotnet test"
+../crabbox/bin/crabbox run --provider ssh --target windows --windows-mode wsl2 --static-host win-dev.local -- pnpm test
+```
+
+- `target=macos` and `target=windows --windows-mode wsl2` use the POSIX SSH,
+  bash, Git, rsync, and tar contract.
+- Native Windows uses OpenSSH, PowerShell, Git, and tar; sync is manifest tar
+  archive transfer into `static.workRoot`. Direct native Windows runs support
+  `--script*`, `--env-from-profile`, `--preflight`, and PowerShell `--shell`.
+- `crabbox actions hydrate/register` are Linux-only today; use plain
+  `crabbox run` loops for static macOS and Windows hosts.
+- Live proof needs a reachable, operator-managed SSH host. Without one, verify
+  with `../crabbox/bin/crabbox run --help`, config/flag tests, and the Crabbox
+  Go test suite.
+
+## Direct Brokered AWS Backend
+
+Use this when the task needs direct AWS Crabbox semantics rather than the
+prepared Blacksmith Testbox CI environment.
+
+Changed gate:
+
+```sh
+pnpm crabbox:run -- \
+  --idle-timeout 90m \
+  --ttl 240m \
+  --timing-json \
+  --shell -- \
+  "env CI=1 NODE_OPTIONS=--max-old-space-size=4096 OPENCLAW_TEST_PROJECTS_PARALLEL=6 OPENCLAW_VITEST_MAX_WORKERS=1 OPENCLAW_VITEST_NO_OUTPUT_TIMEOUT_MS=900000 pnpm test:changed"
+```
+
+Full suite:
+
+```sh
+pnpm crabbox:run -- \
+  --idle-timeout 90m \
+  --ttl 240m \
+  --timing-json \
+  --shell -- \
+  "env CI=1 NODE_OPTIONS=--max-old-space-size=4096 OPENCLAW_TEST_PROJECTS_PARALLEL=6 OPENCLAW_VITEST_MAX_WORKERS=1 OPENCLAW_VITEST_NO_OUTPUT_TIMEOUT_MS=900000 pnpm test"
+```
+
+Focused rerun:
+
+```sh
+pnpm crabbox:run -- \
+  --idle-timeout 90m \
+  --ttl 240m \
+  --timing-json \
+  --shell -- \
+  "env CI=1 NODE_OPTIONS=--max-old-space-size=4096 OPENCLAW_VITEST_MAX_WORKERS=1 OPENCLAW_VITEST_NO_OUTPUT_TIMEOUT_MS=900000 pnpm test <path-or-filter>"
+```
+
+Read the JSON summary. Useful fields:
+
+- `provider`: `aws`
+- `leaseId`: `cbx_...`
+- `syncDelegated`: `false`
+- `commandPhases`: populated when the command prints `CRABBOX_PHASE:<name>`
+- `commandMs` / `totalMs`
+- `exitCode`
+
+Crabbox should stop one-shot AWS leases automatically after the run. Verify
+cleanup when a run fails, is interrupted, or the command output is unclear:
+
+```sh
+../crabbox/bin/crabbox list --provider aws
+```
+
+## Blacksmith Testbox Through Crabbox
+
+Use this for OpenClaw maintainer broad/heavy `pnpm` gates when the prepared CI
+environment is the right proof surface:
+
+```sh
+node scripts/crabbox-wrapper.mjs run \
+  --provider blacksmith-testbox \
+  --blacksmith-org openclaw \
+  --blacksmith-workflow .github/workflows/ci-check-testbox.yml \
+  --blacksmith-job check \
+  --blacksmith-ref main \
+  --idle-timeout 90m \
+  --ttl 240m \
+  --timing-json \
+  -- \
+  CI=1 NODE_OPTIONS=--max-old-space-size=4096 OPENCLAW_TEST_PROJECTS_PARALLEL=6 OPENCLAW_VITEST_MAX_WORKERS=1 OPENCLAW_VITEST_NO_OUTPUT_TIMEOUT_MS=900000 OPENCLAW_TESTBOX=1 OPENCLAW_TESTBOX_REMOTE_RUN=1 pnpm check:changed
+```
+
+Read the JSON summary and the Testbox line. Useful fields:
+
+- `provider`: `blacksmith-testbox`
+- `leaseId`: `tbx_...`
+- `syncDelegated`: `true`
+- `syncPhases`: delegated/skipped because Blacksmith owns checkout/sync
+- Actions run URL/id from the Testbox output
+- `exitCode`
+
+`blacksmith testbox list` may hide hydrating or ready boxes. Use:
+
+```sh
+blacksmith testbox list --all
+blacksmith testbox status <tbx_id>
+```
+
+## Observability Flags
+
+Use these on debugging runs before inventing ad hoc logging:
+
+- `--preflight`: prints run context, workspace mode, SSH target, remote user/cwd,
+  and target-specific tool probes. Defaults cover `git`, `tar`, `node`, `npm`,
+  `corepack`, `pnpm`, `yarn`, `bun`, `docker`, plus POSIX
+  `sudo`/`apt`/`bubblewrap` and native Windows
+  `powershell`/`execution_policy`/`longpaths`/`temp`/`pwsh`. Add
+  `--preflight-tools node,bun,docker`, `CRABBOX_PREFLIGHT_TOOLS`, or repo
+  `run.preflightTools` to replace the list. `default` expands built-ins; `none`
+  prints only the workspace summary. Preflight is diagnostic only; install
+  toolchains through Actions hydration, images, devcontainer/Nix/mise/asdf, or
+  the run script. On `blacksmith-testbox`, this prints a delegated-unsupported
+  note because the workflow owns setup.
+- `CRABBOX_ENV_ALLOW=NAME,...`: forwards only listed local env vars for direct
+  providers and prints `set len=N secret=true` style summaries. On
+  `blacksmith-testbox`, env forwarding is unsupported; put secrets in the
+  Testbox workflow instead.
+- `--env-from-profile <file>` plus `--allow-env NAME`: loads simple
+  `export NAME=value` / `NAME=value` lines from a local profile without
+  executing it, then forwards only allowlisted names. `--allow-env` is
+  repeatable and comma-separated. Profile values override ambient allowlisted
+  env values for that run. Direct POSIX, WSL2, and native Windows runs are
+  supported; delegated providers are not. Crabbox probes the uploaded profile
+  remotely and prints redacted presence/length metadata before the command.
+- `--env-helper <name>`: with `--env-from-profile` on POSIX SSH targets,
+  persists `.crabbox/env/<name>` and `.crabbox/env/<name>.env` so follow-up
+  commands on the same lease can run through `./.crabbox/env/<name> <command>`.
+  Use only on leases you control; the profile stays until cleanup, lease reset,
+  or `--full-resync`.
+- `--script <file>` / `--script-stdin`: upload a local script into
+  `.crabbox/scripts/` and execute it on the remote box. Shebang scripts execute
+  directly on POSIX; scripts without a shebang run through `bash`. Native
+  Windows uploads run through Windows PowerShell, and Crabbox appends `.ps1`
+  when needed. Arguments after `--` become script args.
+- `--fresh-pr owner/repo#123|URL|number`: skip dirty local sync and create a
+  fresh remote checkout of the GitHub PR. Bare numbers use the current repo's
+  GitHub origin. Add `--apply-local-patch` only when the current local
+  `git diff --binary HEAD` should be applied on top of that PR checkout.
+- `--full-resync` / `--fresh-sync`: reset a stale direct-provider workdir
+  before syncing. Use after sync fingerprints look wrong, SSH times out before
+  sync, or rsync watchdog output suggests it. It is redundant with
+  `--fresh-pr`, incompatible with `--no-sync`, and unsupported by delegated
+  providers.
+- `--capture-stdout <path>` / `--capture-stderr <path>`: write remote streams to
+  local files and keep binary/noisy output out of retained logs. Parent
+  directories must already exist. These are direct-provider only.
+- `--capture-on-fail`: on non-zero direct-provider exits, downloads
+  `.crabbox/captures/*.tar.gz` with `test-results`, `playwright-report`,
+  `coverage`, JUnit XML, and nearby logs. Treat as secret-bearing until reviewed.
+- `--keep-on-failure`: leave a failed one-shot lease alive for live debugging
+  until idle/TTL expiry. Useful on direct providers and delegated one-shots.
+- `--timing-json`: final machine-readable timing. Add
+  `echo CRABBOX_PHASE:install`, `CRABBOX_PHASE:test`, etc. in long shell
+  commands; direct providers and Blacksmith Testbox both report them as
+  `commandPhases`.
+
+Live-provider debug template for direct AWS/Hetzner leases:
+
+```sh
+mkdir -p .crabbox/logs
+pnpm crabbox:run -- --provider aws \
+  --preflight \
+  --allow-env OPENAI_API_KEY,OPENAI_BASE_URL \
+  --timing-json \
+  --capture-stdout .crabbox/logs/live-provider.stdout.log \
+  --capture-stderr .crabbox/logs/live-provider.stderr.log \
+  --capture-on-fail \
+  --shell -- \
+  "echo CRABBOX_PHASE:install; pnpm install --frozen-lockfile; echo CRABBOX_PHASE:test; pnpm test:live"
+```
+
+Do not pass `--capture-*`, `--download`, `--checksum`, `--force-sync-large`, or
+`--sync-only` to delegated providers. Also do not pass `--script*`,
+`--fresh-pr`, `--full-resync`, or `--env-helper` there. Crabbox rejects these
+because the provider owns sync or command transport. `--keep-on-failure` is OK
+for delegated one-shots when you need to inspect a failed lease.
+
+## Efficient Bug E2E Verification
+
+Use the smallest Crabbox lane that proves the reported user path, not just the
+touched code. Aim for one after-fix E2E proof before commenting, closing, or
+opening a PR for a user-visible bug.
+
+When the user says "test in Crabbox", do not simply copy tests to the remote
+box and run them there. Crabbox is for remote real-scenario proof: copy or
+install OpenClaw as the user would, run the same setup/update/CLI/Gateway/API
+call that failed, and capture behavior from that entrypoint. For regressions or
+bug reports, prove the broken state first when feasible, then run the same
+scenario after the fix.
+
+Pick the lane by symptom:
+
+- Docker/setup/install bug: build a package tarball and run the matching
+  `scripts/e2e/*-docker.sh` or package script. This proves npm packaging,
+  install paths, runtime deps, config writes, and container behavior.
+- Provider/model/auth bug: prefer true live E2E. Use the configured secret
+  workflow, then inject the single needed key into Crabbox if needed. Scrub
+  unrelated provider env vars in the child command so interactive defaults do
+  not drift to another provider. If only a dummy key is used, label the proof
+  narrowly, e.g. "UI/install path only; live provider auth not exercised."
+- Channel delivery bug: use the channel Docker/live lane when available; include
+  setup, config, gateway start, send/receive or agent-turn proof, and redacted
+  logs.
+- Gateway/session/tool bug: prefer an end-to-end CLI or Gateway RPC command that
+  creates real state and inspects the resulting files/API output.
+- Pure parser/config bug: targeted tests may be enough, but still run a
+  Crabbox command when OS, package, Docker, secrets, or service lifecycle could
+  change behavior.
+
+Efficient flow:
+
+1. Reproduce or prove the pre-fix symptom from the real user-facing entrypoint
+   when feasible. If the issue cannot be reproduced, capture the exact command
+   and observed behavior instead.
+2. Patch locally and run narrow local tests for edit speed.
+3. Run one Crabbox E2E command that starts from the user-facing entrypoint:
+   package install, Docker setup, onboarding, channel add, gateway start, or
+   agent turn as appropriate.
+4. Record proof as: Testbox id, command, environment shape, redacted secret
+   source, and copied success/failure output.
+5. If the issue says "cannot reproduce", ask for the missing config/log fields
+   that would distinguish the tested path from the reporter's path.
+
+Keep it efficient:
+
+- Reuse existing E2E scripts and helper assertions before writing ad hoc shell.
+- Use `--script <file>` or `--script-stdin` for multi-line E2E commands instead
+  of quote-heavy `--shell` strings on direct SSH providers.
+- Use `--fresh-pr <pr>` when validating an upstream PR in isolation from the
+  local dirty tree. Add `--apply-local-patch` only when testing a local fixup on
+  top of that PR.
+- Use `--full-resync` before replacing a warmed direct-provider lease when the
+  remote workdir or sync fingerprint appears stale.
+- Use one-shot Crabbox for a single proof; use a reusable Testbox only when
+  several commands must share built images, installed packages, or live state.
+- Prefer `OPENCLAW_CURRENT_PACKAGE_TGZ` with Docker/package lanes when testing a
+  candidate tarball; prefer the repo's package helper instead of direct source
+  execution when the bug might be packaging/install related.
+- Keep secrets redacted. It is fine to report key presence, source, and length;
+  never print secret values.
+- Include `--timing-json` on broad or flaky runs when command duration or sync
+  behavior matters.
+
+Before/after PR proof on delegated Testbox:
+
+- For PRs that should prove "broken before, fixed after", compare base and PR
+  on the same Testbox when practical. Fetch both refs, create detached temp
+  worktrees under `/tmp`, install in each, then run the same harness twice.
+- Do not checkout base/PR refs in the synced repo root. Delegated Testbox sync
+  may leave the root dirty with local files; `git checkout` can abort or mix
+  proof state.
+- Temp harness files under `/tmp` do not resolve repo packages by default. Put
+  the harness inside the worktree, or in ESM use
+  `createRequire(path.join(process.cwd(), "package.json"))` before requiring
+  workspace deps such as `@lydell/node-pty`.
+- For full-screen TUI/CLI bugs, a PTY harness is stronger than helper-only
+  assertions. Use a real PTY, wait for visible lifecycle markers, send input,
+  then send control keys and assert process exit/stuck behavior.
+- When validating a rebased local branch before push, remember delegated sync
+  usually validates synced file content on a detached dirty checkout, not a
+  remote commit object. Record the local head SHA, changed files, Testbox id,
+  and final success markers; after pushing, ensure the pushed SHA has the same
+  file content.
+- If GitHub CI is still queued but the exact changed content passed Testbox
+  `pnpm check:changed`, `pnpm check:test-types`, and the real E2E proof, it is
+  reasonable to merge once required checks allow it. Note any still-running
+  unrelated shards in the proof comment instead of waiting forever.
+
+Interactive CLI/onboarding:
+
+- For full-screen or prompt-heavy CLI flows, run the target command inside tmux
+  on the Crabbox and drive it with `tmux send-keys`; capture proof with
+  `tmux capture-pane`, redacted through `sed`.
+- Prefer deterministic arrow navigation over search typing for Clack-style
+  searchable selects. Raw `send-keys -l openai` may not trigger filtering in a
+  tmux pane; inspect option order locally or on-box and send exact Down/Enter
+  sequences.
+- Isolate mutable state with `OPENCLAW_STATE_DIR=$(mktemp -d)`. Plugin npm
+  installs live under that state dir (`npm/node_modules/...`), not under
+  `OPENCLAW_CONFIG_DIR`. Verify downloads by checking the state dir, package
+  lock, and installed package metadata.
+- To test automatic setup installs against local package artifacts, use
+  `OPENCLAW_ALLOW_PLUGIN_INSTALL_OVERRIDES=1` plus
+  `OPENCLAW_PLUGIN_INSTALL_OVERRIDES='{"plugin-id":"npm-pack:/tmp/plugin.tgz"}'`.
+  Pack with `npm pack`, set an isolated `OPENCLAW_STATE_DIR`, and verify the
+  package under `npm/node_modules`. Overrides are test-only and must not be
+  treated as official/trusted-source installs.
+- For OpenAI/Codex onboarding proof, the useful markers are the UI line
+  `Installed Codex plugin`, `npm/node_modules/@openclaw/codex`, and the
+  package-lock entry showing the bundled `@openai/codex` dependency. A dummy
+  OpenAI-shaped key can prove only UI/install behavior; it is not live auth.
+
+## Reuse And Keepalive
+
+For most Crabbox calls, one-shot is enough. Use reuse only when you need
+multiple manual commands on the same hydrated box.
+
+If Crabbox returns a reusable id or you intentionally keep a lease:
+
+```sh
+pnpm crabbox:run -- --id <cbx_id-or-slug> --no-sync --timing-json --shell -- "pnpm test <path>"
+```
+
+Stop boxes you created before handoff:
+
+```sh
+pnpm crabbox:stop -- <id-or-slug>
+blacksmith testbox stop --id <tbx_id>
+```
+
+## Interactive Desktop And WebVNC
+
+Prefer WebVNC for human inspection because the browser portal can preload the
+lease VNC password and avoids a native VNC client's copy/paste/password dance.
+Use native `crabbox vnc` only when WebVNC is unavailable, the browser portal is
+broken, or the user explicitly wants a local VNC client.
+
+Common desktop flow:
+
+```sh
+../crabbox/bin/crabbox warmup --provider hetzner --desktop --browser --class standard --idle-timeout 60m --ttl 240m
+../crabbox/bin/crabbox desktop launch --provider hetzner --id <cbx_id-or-slug> --browser --url https://example.com --webvnc --open --take-control
+```
+
+Useful WebVNC commands:
+
+```sh
+../crabbox/bin/crabbox webvnc --provider hetzner --id <cbx_id-or-slug> --open --take-control
+../crabbox/bin/crabbox webvnc daemon start --provider hetzner --id <cbx_id-or-slug> --open --take-control
+../crabbox/bin/crabbox webvnc daemon status --provider hetzner --id <cbx_id-or-slug>
+../crabbox/bin/crabbox webvnc daemon stop --provider hetzner --id <cbx_id-or-slug>
+../crabbox/bin/crabbox webvnc status --provider hetzner --id <cbx_id-or-slug>
+../crabbox/bin/crabbox webvnc reset --provider hetzner --id <cbx_id-or-slug> --open --take-control
+../crabbox/bin/crabbox desktop doctor --provider hetzner --id <cbx_id-or-slug>
+../crabbox/bin/crabbox desktop click --provider hetzner --id <cbx_id-or-slug> --x 640 --y 420
+../crabbox/bin/crabbox desktop paste --provider hetzner --id <cbx_id-or-slug> --text "user@example.com"
+../crabbox/bin/crabbox desktop key --provider hetzner --id <cbx_id-or-slug> ctrl+l
+../crabbox/bin/crabbox artifacts collect --id <cbx_id-or-slug> --all --output artifacts/<slug>
+../crabbox/bin/crabbox artifacts publish --dir artifacts/<slug> --pr <number>
+```
+
+`desktop launch --webvnc --open` is usually the nicest one-shot: it starts the
+browser/app inside the visible session, bridges the lease into the authenticated
+WebVNC portal, and opens the portal. Keep browsers windowed for human QA; use
+`--fullscreen` only for capture/video workflows.
+For human handoff, include `--take-control` so the opened portal viewer gets
+keyboard/mouse control automatically instead of landing as an observer.
+
+Human handoff preflight:
+
+- Do not assume a visible desktop or launched browser means the repo CLI/app is
+  installed, built, or on the interactive terminal's `PATH`.
+- Before handing WebVNC to a human tester, prove the expected command from the
+  same kept lease and from a neutral directory such as `~`.
+- If the handoff needs repo-local code, sync/build/link it explicitly on that
+  lease. Source-tree CLIs often need build output before a symlink works.
+- Prefer a real `command -v <expected-command> && <expected-command> --version`
+  check over a repo-root-only `pnpm ...` command.
+
+Generic handoff repair pattern:
+
+```sh
+../crabbox/bin/crabbox run --id <cbx_id-or-slug> --full-resync --shell -- \
+  "set -euo pipefail
+   pnpm install --frozen-lockfile
+   pnpm build
+   sudo ln -sf \"\$PWD/<cli-entry>\" /usr/local/bin/<expected-command>
+   cd ~
+   command -v <expected-command>
+   <expected-command> --version"
+```
+
+## If Crabbox Fails
+
+Keep the fallback narrow. First decide whether the failure is Crabbox itself,
+the brokered AWS lease, Blacksmith/Testbox, repo hydration, sync, or the test
+command.
+
+Fast checks:
+
+```sh
+command -v crabbox
+../crabbox/bin/crabbox --version
+pnpm crabbox:run -- --help | sed -n '1,140p'
+../crabbox/bin/crabbox doctor
+command -v blacksmith
+blacksmith --version
+blacksmith testbox list
+```
+
+Common Crabbox-only failures:
+
+- Provider missing or old CLI: use `../crabbox/bin/crabbox` from the sibling
+  repo, or update/install Crabbox before retrying.
+- Bad local config: inspect `.crabbox.yaml`, `crabbox config show`, and
+  `crabbox whoami`; normal OpenClaw proof should use brokered AWS without
+  asking for cloud keys.
+- Slug/claim confusion: use the raw `cbx_...` / `tbx_...` id, or run one-shot
+  without `--id`.
+- Sync/timing bug: add `--debug --timing-json`; capture the final JSON and the
+  printed Actions URL. Large sync warnings now include top source directories
+  by file count and a hint to update `.crabboxignore` / `sync.exclude`; inspect
+  those before reaching for `--force-sync-large`. Quiet rsync watchdogs and SSH
+  timeouts now print `next_action=` hints; follow them, usually `--full-resync`
+  first and a fresh lease second.
+- Cleanup uncertainty: run `crabbox list --provider aws`; for explicit
+  Blacksmith runs, use `blacksmith testbox list` and stop only boxes you
+  created.
+- Testbox queued/capacity pressure: do not retry Blacksmith repeatedly. Rerun
+  once without `--provider` so `.crabbox.yaml` routes to brokered AWS, or report
+  the Blacksmith blocker if Testbox itself is the requested proof.
+
+If brokered AWS cannot dispatch, sync, attach, or stop, retry once with
+`--debug` and `--timing-json`:
+
+```sh
+pnpm crabbox:run -- --debug --timing-json -- \
+  CI=1 NODE_OPTIONS=--max-old-space-size=4096 OPENCLAW_TEST_PROJECTS_PARALLEL=6 OPENCLAW_VITEST_MAX_WORKERS=1 OPENCLAW_VITEST_NO_OUTPUT_TIMEOUT_MS=900000 pnpm test:changed
+```
+
+Full suite:
+
+```sh
+pnpm crabbox:run -- --debug --timing-json -- \
+  CI=1 NODE_OPTIONS=--max-old-space-size=4096 OPENCLAW_TEST_PROJECTS_PARALLEL=6 OPENCLAW_VITEST_MAX_WORKERS=1 OPENCLAW_VITEST_NO_OUTPUT_TIMEOUT_MS=900000 pnpm test
+```
+
+Auth fallback, only when `blacksmith` says auth is missing:
+
+```sh
+blacksmith auth login --non-interactive --organization openclaw
+```
+
+Raw Blacksmith footguns:
+
+- Run from repo root. The CLI syncs the current directory.
+- Save the returned `tbx_...` id in the session.
+- Reuse that id for focused reruns; stop it before handoff.
+- Raw commit SHAs are not reliable `warmup --ref` refs; use a branch or tag.
+- Treat `blacksmith testbox list` as cleanup diagnostics, not a shared reusable
+  queue.
+
+Use Blacksmith only when the task is specifically about Testbox, brokered AWS
+is unavailable, or an explicit comparison is needed. If Blacksmith is down or
+quota-limited, do not keep probing it; stay on brokered AWS and note the
+delegated-provider outage.
+
+## Blacksmith Backend Notes
+
+Crabbox Blacksmith backend delegates setup to:
+
+- org: `openclaw`
+- workflow: `.github/workflows/ci-check-testbox.yml`
+- job: `check`
+- ref: `main` unless testing a branch/tag intentionally
+
+The hydration workflow owns checkout, Node/pnpm setup, dependency install,
+secrets, ready marker, and keepalive. Crabbox owns dispatch, sync, SSH command
+execution, timing, logs/results, and cleanup.
+
+Minimal Blacksmith-backed Crabbox run, from repo root:
+
+```sh
+pnpm crabbox:run -- --provider blacksmith-testbox --timing-json -- \
+  CI=1 NODE_OPTIONS=--max-old-space-size=4096 OPENCLAW_TEST_PROJECTS_PARALLEL=6 OPENCLAW_VITEST_MAX_WORKERS=1 pnpm test:changed
+```
+
+Use direct Blacksmith only when Crabbox is the broken layer and you are
+isolating a Crabbox bug. Prefer direct `blacksmith testbox list` for cleanup
+diagnostics, not as a reusable work queue.
+
+Important Blacksmith footguns:
+
+- Always run from repo root. The CLI syncs the current directory.
+- Raw commit SHAs are not reliable `warmup --ref` refs; use a branch or tag.
+- If auth is missing and browser auth is acceptable:
+
+```sh
+blacksmith auth login --non-interactive --organization openclaw
+```
+
+## Brokered AWS
+
+Use AWS for normal OpenClaw remote proof. The repo `.crabbox.yaml` already
+selects brokered AWS, so omit `--provider` unless you are testing a different
+provider deliberately.
+
+```sh
+pnpm crabbox:warmup -- --class beast --market on-demand --idle-timeout 90m
+pnpm crabbox:hydrate -- --id <cbx_id-or-slug>
+pnpm crabbox:run -- --id <cbx_id-or-slug> --timing-json --shell -- "env NODE_OPTIONS=--max-old-space-size=4096 OPENCLAW_TEST_PROJECTS_PARALLEL=6 OPENCLAW_VITEST_MAX_WORKERS=1 OPENCLAW_VITEST_NO_OUTPUT_TIMEOUT_MS=900000 pnpm test:changed"
+pnpm crabbox:stop -- <cbx_id-or-slug>
+```
+
+Install/auth for owned Crabbox if needed:
+
+```sh
+brew install openclaw/tap/crabbox
+crabbox login --url https://crabbox.openclaw.ai --provider aws
+```
+
+New users should self-resolve broker auth before anyone asks for AWS keys:
+
+```sh
+crabbox config show
+crabbox doctor
+crabbox whoami
+```
+
+- If broker auth is missing, run `crabbox login --url https://crabbox.openclaw.ai --provider aws`.
+- If the CLI asks for `AWS_ACCESS_KEY_ID`, `AWS_SECRET_ACCESS_KEY`, or AWS
+  profile setup during normal OpenClaw validation, assume the agent selected
+  the wrong path. Use brokered `crabbox login` or an existing brokered lease
+  before asking the user for cloud credentials.
+- Ask for AWS keys only for explicit direct-provider/account administration,
+  not for normal brokered OpenClaw proof.
+- Trusted automation may still use
+  `printf '%s' "$CRABBOX_COORDINATOR_TOKEN" | crabbox login --url https://crabbox.openclaw.ai --provider aws --token-stdin`.
+
+macOS config lives at:
+
+```text
+~/Library/Application Support/crabbox/config.yaml
+```
+
+It should include `broker.url`, `broker.token`, and usually `provider: aws`
+for OpenClaw lanes. Let that config drive normal validation.
+
+### Interactive Desktop / WebVNC
+
+For human desktop demos, prefer `webvnc` over native `vnc` and keep the remote
+desktop visible/windowed. Do not fullscreen the remote browser or hide the XFCE
+panel/window chrome unless the explicit goal is video/capture output. After
+launch, verify a screenshot shows the desktop panel plus browser title bar. If
+Chrome is fullscreen, toggle it back with:
+
+```sh
+crabbox run --id <lease> --shell -- 'DISPLAY=:99 xdotool search --onlyvisible --class google-chrome windowactivate key F11'
+```
+
+## Diagnostics
+
+```sh
+crabbox status --id <id-or-slug> --wait
+crabbox inspect --id <id-or-slug> --json
+crabbox sync-plan
+crabbox history --limit 20
+crabbox history --lease <id-or-slug>
+crabbox attach <run_id>
+crabbox events <run_id> --json
+crabbox logs <run_id>
+crabbox results <run_id>
+crabbox cache stats --id <id-or-slug>
+crabbox ssh --id <id-or-slug>
+blacksmith testbox list
+```
+
+Use `--debug` on `run` when measuring sync timing.
+Use `--timing-json` on warmup, hydrate, and run when comparing backends.
+Use `--market spot|on-demand` only on AWS warmup/one-shot runs.
+
+## Failure Triage
+
+- Crabbox cannot find provider: verify `../crabbox/bin/crabbox --help` lists
+  the provider selected by `.crabbox.yaml`; update Crabbox before falling back.
+- Hydration stuck or failed: open the printed GitHub Actions run URL and inspect
+  the hydration step.
+- Sync failed: rerun with `--debug`; check changed-file count and whether the
+  checkout is dirty.
+- Command failed: rerun only the failing shard/file first. Do not rerun a full
+  suite until the focused failure is understood.
+- Cleanup uncertain: `crabbox list --provider aws`; for explicit Blacksmith
+  runs, use `blacksmith testbox list` and stop owned `tbx_...` leases you
+  created.
+- Crabbox broken but Blacksmith works: use the direct Blacksmith fallback above,
+  then file/fix the Crabbox issue.
+
+## Boundary
+
+Do not add OpenClaw-specific setup to Crabbox itself. Put repo setup in the
+hydration workflow and keep Crabbox generic around lease, sync, command
+execution, logs/results, timing, and cleanup.
