Explanation
Directly linked issue
#64has coding requirements for per-target dependency closures, reduced budgets, no functional change, and smoke checks for every target and architecture. The reviewed head implements the main structure.deploy/docker/prepare-container-targets.mjsstages separate core, browser, and cli trees.scripts/container-image-size-budget.mjsand its test use the lowered limits of 850, 1350, and 1000 MiB..github/workflows/containers.ymladds core and CLI smoke checks forlinux/amd64andlinux/arm64.The browser smoke check is unchanged from the previous review. The head file runs
docker run --rm --entrypoint chromium spaceapp-ci:browser-${arch} --no-sandbox --headless --disable-gpu --dump-dom about:blank. This bypassesdeploy/docker/browser-entrypoint.sh, which runsapps/api/dist/browser-host-main.js. The issue requires that the browser image start the Browser Host and launch headless Chromium once. That requirement is not met. No automated coverage of the Browser Host launch path was found in the reviewed evidence.The launcher check in the issue is a manual verification item. It was not used for this coding verdict.
Resolution
In
.github/workflows/containers.yml, change the browser smoke step to start the browser image through its Browser Host entrypoint. Supply the database URL secret thatbrowser-entrypoint.shreads throughSPACE_DATABASE_URL_FILE. Verify Browser Host readiness and one headless Chromium launch through the Browser Host on both matrix architectures. Add automated test coverage for that Browser Host launch path.

Explanation
The reviewed changes mostly support
#64. These include the per-target staging script, the Dockerfile stage split, budget changes, CI smoke checks, the lazynode-ptyloading inpackages/cli-host/src/node-pty-spawn.ts, and the disk-threshold documentation updates.The whole-PR summary also lists changes to
apps/api/package.jsonthat do not relate to any#64requirement. The summary reports a license change fromMITtoBUSL-1.1, the addition of@fastify/cors, and changes to thesanitize-htmlandvitestversion ranges. The reviewed head shows"license": "BUSL-1.1"and@fastify/corsin that file. Neither the issue nor the PR description requests these changes. The base version of the file could not be read, so the prior state of these fields is not independently confirmed. The summary is the evidence for these changes.The
node-ptyremoval fromapps/api/package.jsonis related to per-target dependency closure and is not counted here.Resolution
Remove the unrelated
apps/api/package.jsonchanges, including the license change, the@fastify/corsaddition, and thesanitize-htmlandvitestrange changes. Keep them only if the PR shows a concrete link to#64requirements. Keep thenode-ptyremoval.

- Around line 133-135: Keep the CLI host and terminal dependencies in the core
target: update the core package selection to include cli-host, and remove the
exclusions in prepare-container-targets that delete packages/cli-host,
@space/cli-host, node-pty, and @xterm. Preserve the browser-host-main.js
exclusion.
Review comments at @scripts/container-image-size-budget.mjs:
- Around line 7-14: Update the containerImageSizeBudgets entries for core,
browser, and cli to record measured image sizes separately for linux/amd64 and
linux/arm64, replacing the approximate ceilings with auditable
architecture-specific limits.

- Around line 83-86: Update the PostgreSQL readiness loop to use `_` for the
unused iteration variable and explicitly fail with a clear message if
`pg_isready` does not succeed within 30 attempts. Ensure the failure is checked
after the loop so the smoke check stops before proceeding.
- Around line 128-135: Replace the fixed sleep in the smoke check with a retry
loop that waits for `/run/spaceapp-cli/host.sock` to exist, and use `docker
inspect` to confirm the container is still running before attempting the
connection test. Keep the existing socket connection check in place.
- Around line 75-111: Move cleanup for the core and CLI container smoke checks
out of their run scripts into separate cleanup steps that run with `if:
always()`, so failures do not skip cleanup; in those steps, print the relevant
containers’ logs when the smoke-check step fails, then stop and remove the
containers, networks, and temporary secrets.

Fixes #64
Closes #64
Summary
Refactors the container build pipeline so each runtime target (
core,browser,cli) ships only the workspace packages, runtime assets, and production dependencies it actually executes, eliminating cross-service bloat while preserving strict public-export compatibility.Measured Image Sizes (Dual Architecture) vs Enforced Budgets
