chore(infra): bin/setup installs pinned Chromium for the suite - #84
Conversation
`bin/setup` (#82) installs bun deps and builds the dummy/web fixture, but the suite still drives a real Chromium and nothing installed one — the fleet box went red on an unmodified checkout with "Chromium distribution 'chrome' is not found at /opt/google/chrome/chrome" (issue #83). Mirror the install logic from ci.yml: - use `node node_modules/playwright-core/cli.js install chromium` (not `bunx playwright`, which exits 0 in 0.7s without fetching the headless shell the pinned version requires); - no apt / install-deps — the system libs are on the stock image and the Ubuntu mirrors are what flake; - bounded retry (`timeout --kill-after=30 300`, 3 attempts, backoff `sleep \$((attempt * 20))`) so a wedged CDN fetch cannot hang setup; - skip when both INSTALLATION_COMPLETE markers (the canonical "is it there" signal playwright-core's own registry checks) are present, so re-running bin/setup with the browser on disk does NOT re-download; - end with the same "verify chromium launches" ci.yml does, so a missing binary or system lib fails setup HERE with the error naming it, not as a mystery inside bin/check / bun test. No change to ci.yml, package.json, or src/. Co-Authored-By: Claude Code <noreply@anthropic.com>

PR #84 adds Chromium installation to bin/setup, mirroring CI's install logic. The diff is clean: idempotency checks use the correct INSTALLATION_COMPLETE markers, the retry loop has proper backoff, the launch verification catches missing binaries, and the script respects…
No findings from: concern-security.

installation loop so the timeout-wrapped Playwright Chromium install runs within
an if condition, allowing its exit status to be captured in rc without set -e

Review summary — 1 file(s), 0 finding(s).
Installs pinned Chromium for the suite with retry logic that actually runs — the || rc=$? pattern prevents set -e from exiting on first failure, enabling the 3-attempt loop to function as intended. Clean fix addressing a real bug.

Closes #83
What changed
bin/setup(#82) installs bun deps and buildsdummy/web, but the suitedrives a real Chromium and nothing installed one — measured on the first
run after #82 landed (for #80), the gate RAN this time and went red on an
unmodified checkout with
AdapterError: browser.create failed: cannot launch Chrome — launchPersistentContext: Chromium distribution 'chrome' is not found at /opt/google/chrome/chrome.This PR makes
bin/setupinstall the browser, mirroring the installlogic from
.github/workflows/ci.yml— both files share the two hard-wonfacts that file already records:
bunx playwright:bunxresolves anunpinned version that "exit 0 in 0.7s without fetching the headless
shell the pinned version requires" (ci.yml:71-73). The command is the
verbatim
node node_modules/playwright-core/cli.js install chromium.the stock image, and the Ubuntu mirrors are what flake (ci.yml:59-66).
The launch check at the end of
bin/setupgates that claim at runtime.Plus the rest of what CI learned to need:
timeout --kill-after=30 300, 3 attempts,backoff
sleep $((attempt * 20)). A wedged or crawling CDN fetchcannot hang a box's setup indefinitely; exit 124/137 is logged as
such.
INSTALLATION_COMPLETEmarkers(the canonical "is it there" signal playwright-core's own registry
checks on subsequent runs, robust to the chrome-linux → chrome-linux64
layout move) are present. Re-running
bin/setupwith the browser ondisk does NOT re-download; verified:
==> chromium 1228 + headless_shell already at /home/ivann/.cache/ms-playwright, skipping install.bun -e '… chromium.launch({ headless: true }) …'ci.yml does. A missing binary or system lib fails HEREwith the error naming it (e.g. "Chromium distribution 'X' is not
found at Y" — same shape as the issue's baseline-red), not as a
mystery inside
bin/check/bun test. Not retried: a missingbinary or library is not transient.
No change to
.github/workflows/ci.yml,package.json,tsconfig*,or any file under
src/.Empirical proof
Each command run BARE, real exit code read.

is the gate.
What is incomplete / caveats
bin/checkdoes NOT exit 0 on this checkout, even on theunmodified tree. There is a pre-existing flake in
src/services/session-builder.test.ts:476("a persona signs the runin before the first step, and leaves no credential in the logs") that
is unrelated to chromium installation: the chromium binary
launches fine (verified by the
bin/setuplaunch check AND by theother two CHROME-gated tests in the same file passing consistently).
The flake is in the auth form-submission → URL-change timing: the
Bun.servelogin fixture submits afetch, then on success setslocation.href = '/dashboard'; the auth flow'snetworkIdlesettlesometimes returns before that navigation completes, so the URL check
in
assertSignedInsees/loginand throws.git stash-ed this branch'sbin/setupto leave the tree at the unmodified state, ran the test 5 times,
saw it pass once and fail four times. Reverted the stash.
src/(issue rule + global HARD PROHIBITION), soI cannot fix the flake here. The
bin/setupchanges themselvesare correct and complete; the red
bin/checkis a separate ticketagainst
src/services/session-builder.test.ts. The issue'sacceptance criterion "the baseline is green" cannot be met on this
checkout regardless of what
bin/setupdoes.bin/installwas not re-verified becausebin/setupdoes notexist as a separate script (only
bin/setupandbin/check).Files touched
