feat(dx): Phase 1 — universal dev environment setup

[spbolton]

Summary

• Unified tool management via mise (.mise.toml) replacing nvm/sdkman/pyenv — works in interactive shells, non-interactive shells (Claude Code, git hooks), and CI/CD
• Command runner via just (justfile) with just setup → just build → just dev workflow
• Git hooks via lefthook replacing husky + lint-staged
• Shared services (PostgreSQL + OpenSearch) for parallel development across multiple project folders
• Folder-based container/image naming — each project folder gets its own Docker namespace derived from its directory name, avoiding collisions
• Frontend dev server management (dev-start-frontend, dev-stop-frontend, etc.)
• AI agent context architecture — five-layer instruction system (root, rules, directory, skills, docs) with decision framework
• Path-scoped rules for Java, Angular, testing, CI/CD, shell scripts

Design principle

This phase works in any project folder — whether a regular clone, a git worktree, or a Cursor/Codex workspace — without assuming any particular worktree tooling. Container isolation uses the folder name, not the branch name.

Phase 2 (stacked PR) will add worktrunk integration for warm-start worktrees with copy-on-write caches, deterministic port assignment, and agent spawning patterns.

Test plan

• just setup completes without errors on a fresh clone
• just _project-slug returns the folder basename
• just build tags the Docker image with folder-based slug
• just dev-run starts the stack using folder-based container naming
• just dev-shared-start + just dev-run auto-detects shared services
• No references to worktrunk, wt switch, or _worktree-slug in Phase 1 files

❌ Issue Linking Required

This PR could not be linked to an issue. All PRs must be linked to an issue for tracking purposes.

How to fix this:

Option 1: Add keyword to PR body (Recommended - auto-removes this comment)
Edit this PR description and add one of these lines:

• This PR fixes #123 or Fixes: #123

• This PR closes #123 or Closes: #123

• This PR resolves #123 or Resolves: #123

• Other supported keywords: fix, fixed, close, closed, resolve, resolved
  Option 2: Link via GitHub UI (Note: won't clear the failed check)

1. Go to the PR → Development section (right sidebar)

2. Click "Link issue" and select an existing issue

3. Push a new commit or re-run the workflow to clear the failed check
   Option 3: Use branch naming
   Create a new branch with one of these patterns:

• 123-feature-description (number at start)

• issue-123-feature-description (issue-number at start)

• feature-issue-123 (issue-number anywhere)

Why is this required?

Issue linking ensures proper tracking, documentation, and helps maintain project history. It connects your code changes to the problem they solve.---

PR Review

Note on previous Claude comment: The rollback risk assessment about numberContents GraphQL removal was completely wrong — those files are not in this PR. Disregard it.

Issues worth fixing

1. wt.toml cleanup uses branch slug, _project-slug uses folder name — they won't always match

.config/wt.toml post-remove cleanup (lines 35–36):

SLUG=$(echo "{{ branch }}" | sed '...')
CONTAINER="dotbuild_dotcms-core_${SLUG}_dotcms"
docker stop "$CONTAINER" ...

But justfile:_project-slug uses basename $(pwd). In a worktree, the folder name and branch name often differ (e.g., folder core_feature-foo, branch feature/foo). The cleanup targets a container that doesn't exist and exits silently. The same mismatch applies to the image tagging step (docker tag ... dotcms/dotcms-test:{{ branch | sanitize }}), while dev-run looks for dotcms/dotcms-test:${WSLUG} (folder-based). This contradicts the stated design principle that isolation is folder-based, not branch-based.

Either wt.toml should derive the slug the same way _project-slug does (from the worktree path), or document that wt names worktree folders to match sanitized branch names. Fix this →

2. openapi-freshness hook misses REST changes in the current staged commit

lefthook.yml lines 130–151: the freshness check diffs $last_spec_sha..HEAD, which is committed history only. HEAD doesn't include the currently staged files. So if you stage a brand-new @Path annotation as your only REST change since the last spec update, git diff $last_spec_sha..HEAD shows no REST changes → hook exits 0 → spec is not regenerated.

The hook gets it right on the second Java commit after a REST change (the prior REST commit is now in HEAD), but misses it on the first. Fixing this requires also checking {staged_files} for REST annotations, not just committed history:

# After checking committed history — also scan staged files
for f in {staged_files}; do
  [ -f "$f" ] && grep -qE '@Path|@GET|@POST|@PUT|@DELETE|@Operation' "$f" 2>/dev/null && needs_compile=true && break
done

Lower-priority issues

3. lefthook = "latest" — no version pin (mise.toml:9)

Every mise install silently upgrades lefthook, including across major versions. Lefthook v1→v2 had breaking config changes. Pin to a minor version (e.g., lefthook = "1") to control upgrade timing. just = "latest" has the same risk but is less sensitive since just has very stable behavior.

4. _project-slug produces the same slug for all branches in CI (justfile:175)

In GitHub Actions, pwd = /home/runner/work/repo/repo, so basename $(pwd) = core for every job. Docker images get tagged dotcms/dotcms-test:core regardless of branch. On shared self-hosted runners with parallel jobs, images overwrite each other. Passing image= explicitly in CI workflows avoids this, but just build as-called would collide.

5. just setup — curl https://mise.run | sh (justfile:31)

No checksum verification, no version pin. Standard mise install method but fails silently on network issues and is vulnerable to MITM on the download. Consider curl -fsSL https://mise.run at minimum, with a note to verify the checksum if offline installs matter.

6. prepare-commit-msg dispatcher generated but no lefthook config for it (prepare.js:34)

The hook dispatcher is written for prepare-commit-msg, but lefthook.yml has no prepare-commit-msg section. This generates an unnecessary file in .git/hooks/ and calls lefthook run prepare-commit-msg on every commit (which exits 0 silently). Not harmful, but it's dead weight.

Clean

• The shared-services Maven profile and parent/pom.xml parameterization (dot.db.host, dot.db.port, dot.db.name) is clean and properly scoped.
• The 3-stage container discovery in _dotcms-container is robust.
• The _shared-dbname / _project-id uniqueness scheme (prefix + sha256) is sensible.
• prepare.js correctly handles linked worktrees via git rev-parse --git-common-dir.
• The dev-stop-frontend port-scan fallback is a good UX detail.
• Removing the use-license profile is appropriate cleanup.

Pull Request Unsafe to Rollback!!!

• Category: M-3 — REST / GraphQL / Headless API Contract Change
• Risk Level: 🟡 MEDIUM
• Why it's unsafe: The numberContents field is removed from the GraphQL Page API schema without a deprecation period. Any GraphQL client (headless frontend, integration partner, or Angular admin) that queries page { numberContents } will receive a GraphQL validation error (Cannot query field "numberContents" on type "Page") immediately after deployment. Rolling back to N-1 restores the field, but clients that updated their queries in the interim may have already broken the other direction.
• Code that makes it unsafe:
  • dotCMS/src/main/java/com/dotcms/graphql/business/PageAPIGraphQLTypesProvider.java — line removed: pageFields.put("numberContents", new TypeFetcher(GraphQLInt, new NumberContentsDataFetcher()));
  • dotCMS/src/main/java/com/dotcms/graphql/datafetcher/page/NumberContentsDataFetcher.java — entire file deleted
• Alternative (if possible): Follow the standard GraphQL deprecation pattern — mark the field as @deprecated in the schema and keep the implementation for at least one release cycle before removing it. This gives clients time to migrate away from the field before it disappears.
