fix: initialize git submodules and freeze the lockfile in the web session setup hook

[dgarros]

Why

Two independent defects in dev/setup-environment.sh, the SessionStart hook for Claude Code on the web. One is new, one is a backport of a fix already on develop.

1. Submodules are never initialized. The web container clones without --recurse-submodules, so python_sdk and frontend/packages/schema-visualizer are empty when the hook runs. Both are consumed as local paths rather than published packages, and neither installer treats an empty directory as an error — so setup reports success while producing a broken environment.

2. The lockfile churns on every session. A plain pnpm install re-resolves the caret ranges in package.json and picks up whatever transitive versions have been published since the lockfile was committed, rewriting pnpm-lock.yaml. Observed on a real session: oxlint 1.74→1.77, @oxc-parser 0.141→0.143, a new @astrojs/compiler — a 780-line diff nobody asked for. This was fixed on develop in #9972 but never reached stable.

Goal: every web session starts with both submodules populated and a clean working tree, or setup stops with a clear error.

Non-goals: no change to how submodules are pinned or updated, and no change to the Python install command.

What changed

Two commits against stable:

• fix: initialize git submodules in the web session setup hook (new) — runs git submodule update --init --recursive above the Python and frontend installers, then asserts the two expected manifests exist so a partial fetch stops setup instead of silently degrading it. The command is already the canonical one documented in dev/guidelines/git-workflow.md.
• fix(setup): use --frozen-lockfile in setup hook to stop lockfile churn (#9972) — cherry-picked from develop (65efe7bf, provenance recorded via cherry-pick -x). One line, unmodified from the original.

Net: +23 / -1 in one file. No dependency, lockfile, schema, or CI changes. The script still runs exclusively in the claude-code-web environment — the existing SUPPORTED_ENVIRONMENTS gate is untouched, so local and CI runs exit early exactly as before. uv.lock and pnpm-lock.yaml are unmodified.

Why the submodule failures are silent

python_sdk/infrahub_sdk is vendored into the infrahub-server distribution via [tool.hatch.build.targets.wheel.sources], not installed as a separate dependency. With the directory empty, uv sync succeeds and builds a wheel containing no infrahub_sdk — import infrahub works while import infrahub_sdk raises ModuleNotFoundError. 317 backend modules import infrahub_sdk, so anything touching the SDK was broken in every web session.

frontend/packages/schema-visualizer is a pnpm workspace package; with the directory empty pnpm resolves it to a link with no dependency graph and installs 43 fewer packages.

How to review

The submodule block is ordering-sensitive — it must stay above the Python section, which is the entire point of that commit. The second commit is a verbatim cherry-pick; reviewing it against #9972 is enough.

How to test

# Reproduce the broken state a fresh web session starts in
git submodule deinit -f --all

# Run the hook exactly as SessionStart does
CLAUDE_ENV_FILE=1 bash dev/setup-environment.sh

# Verify
uv run --no-sync python -c "import infrahub_sdk, infrahub, infrahub_testcontainers"
git submodule status   # both at pinned commits, no +/- prefix
git status --porcelain # clean -- no lockfile churn

Observed on this branch with both commits applied: exit 0, both submodules checked out at the pinned commits, all three imports succeed, pnpm reports all 5 workspace projects in scope, and the working tree stays clean. Re-running is idempotent. The manifest guard was exercised separately against an empty directory and exits 1 with the expected message.

shellcheck on the file reports only a pre-existing SC2064 at the gh install trap, which this PR leaves alone.

Impact & rollout

• Backward compatibility: none affected. CI already checks out with submodules: true, so CI behavior is unchanged.
• Performance: roughly 4s of submodule cloning per web session; --frozen-lockfile makes the frontend install faster by skipping resolution.
• Config/env changes: none.
• Deployment notes: safe to deploy; takes effect on the next web session.

Checklist

• Tests added/updated — n/a, this is an environment bootstrap script with no test harness; validated by the reproduction above.
• Changelog entry added — deliberately skipped: dev tooling only, no user-facing or ops-facing behavior, so it does not belong in release notes.
• External docs updated — n/a, not user-facing.
• Internal .md docs updated — no change needed; dev/guidelines/git-workflow.md already documents the submodule command, and the change makes the setup script follow it.

Confidence score: 3/5

• In dev/setup-environment.sh, a successful uv sync can still leave infrahub_sdk unimportable while setup reports success, causing downstream failures that are harder to diagnose — re-run the import check after rebuilding and fail setup if it still fails.
• dev/setup-environment.sh has no automated regression coverage for the new manifest-failure and poisoned-venv rebuild paths, so future changes could silently break recovery behavior — add focused tests for both paths.

• dev/setup-environment.sh can swallow a pnpm install failure and still report success, leaving development environments partially broken and making diagnosis harder; propagate the install failure or verify the command result before printing success.

is this like a healthcheck, that submodules were cloned successfully?

[dgarros]

Yes exactly .. not sure if this is really required .. Claude came up with it

[ogenstad]

Something with git submodule status?
