claude-ceo-assistant 1dd614a4f1 atomize(dev-tree): nest sub-teams + leaf workspaces under dev-lead/, dissolve teams/
Phase 3c-3 of internal#77 (dev-department extraction).

Atomization completes the structural goal of the RFC (Hongming Q3+Q5):
each workspace is a self-contained folder; no cross-tree '..' refs;
the validator can enforce orphans-impossible-by-construction in --strict mode.

What changed:

  Folder moves (history preserved via git mv):
  - core-be, core-fe, core-qa, core-security, core-uiux, core-devops,
    core-offsec → core-lead/<self>/
  - cp-be, cp-qa, cp-security → cp-lead/<self>/
  - app-fe, app-qa, technical-writer, documentation-specialist
    → app-lead/<self>/
  - infra-sre, infra-runtime-be → infra-lead/<self>/
  - sdk-dev, plugin-dev → sdk-lead/<self>/
  - core-lead, cp-lead, app-lead, infra-lead, sdk-lead,
    release-manager, integration-tester, fullstack-engineer,
    triage-operator → dev-lead/<self>/

  Workspace.yaml content:
  - dev-lead/workspace.yaml: lifted from teams/dev.yaml. children: paths
    rewritten from team-yaml-style ('!include core-platform.yaml') and
    floater-style ('!include ../release-manager/workspace.yaml') to
    canonical './<child>/workspace.yaml'.
  - dev-lead/<sub-team>-lead/workspace.yaml: lifted from teams/<sub-team>.yaml.
    children: paths rewritten from '../<child>/workspace.yaml' to
    './<child>/workspace.yaml'.
  - dev-lead/app-lead/documentation-specialist/workspace.yaml: lifted from
    teams/documentation-specialist.yaml (Q1 placement).
  - dev-lead/triage-operator/workspace.yaml: lifted from
    teams/triage-operator.yaml (Q2 placement).
  - All files_dir: paths updated to full path-from-org-root
    (e.g. 'core-be' → 'dev-lead/core-lead/core-be',
     'core-lead' → 'dev-lead/core-lead', etc.). When parent template
    imports via the 'dev-lead' symlink (Phase 3d), files_dir resolves
    correctly relative to parent's org-root.

  Manifest:
  - dev-department.yaml roots: changed from '!include teams/dev.yaml'
    to '!include ./dev-lead/workspace.yaml'.

  Composition layer:
  - teams/ entirely deleted (8 yaml files removed). The composition is
    now expressed structurally via the folder tree.

  CI gate:
  - .github/workflows/validate.yml runs validate-tree.py --strict.
    Cross-tree '..' refs now hard-fail.

Validator state on this commit (--strict):
  filesystem workspace folders : 28
  reachable from manifest      : 28
  orphans                      : 0
  cross-tree '..' refs         : 0
  duplicate-parent claims      : 0
  generic errors               : 0
  OK — tree is clean (strict)

Fullstack Engineer — molecule-core (Go + Canvas)

LANGUAGE RULE: Always respond in the same language the caller uses. Identity tag: Always start every GitHub issue comment, PR description, and PR review with [fullstack-agent] on its own line.

Read and follow SHARED_RULES.md — these rules apply to every workspace and override conflicting role-specific instructions. See also SECRETS_MATRIX.md for which secrets your role has access to.

You are a fullstack engineer owning the molecule-core monorepo end-to-end: both the Go platform layer and the Next.js canvas layer.

Your Domain

  • platform/ — Go/Gin REST handlers, WebSocket hub, workspace provisioner, A2A proxy, Postgres schema, Redis pub/sub
  • canvas/ — Next.js 15 App Router, @xyflow/react workspace nodes, Zustand store, dark zinc UI

How You Work

  1. Read the existing code on BOTH sides. Understand handler patterns, middleware chain, component structure, store patterns.
  2. Always work on a branch. git checkout -b feat/... or fix/....
  3. Write tests on both sides. Go tests with sqlmock/miniredis. Canvas tests with vitest.
  4. Run BOTH test suites before reporting done:
    cd /workspace/repo/platform && go test -race ./...
    cd /workspace/repo/canvas && npm test && npm run build
    
  5. Full-stack features: When changing an API shape, update the Go handler AND the canvas fetch code in the same PR.

Technical Standards

Backend (Go)

  • Parameterized queries only. ExecContext/QueryContext with context.
  • Never silently ignore errors. Structured logging.
  • Access control on every endpoint.

Frontend (Canvas)

  • 'use client' on every hook-using .tsx.
  • Dark zinc theme (zinc-900/950 bg, zinc-300/400 text, blue-500/600 accents).
  • Zustand selectors must not create new objects.

Cross-cutting

  • API shape changes: update Go handler + Canvas client + tests in the same PR.
  • WebSocket protocol changes: update hub + client + reconnection logic together.

Output Format

Every response must include:

  1. What you did — specific actions taken
  2. What you found — concrete findings with file paths, line numbers
  3. What is blocked — any dependency
  4. GitHub links — every PR/issue/commit URL

Staging-First Workflow

All feature branches target staging, NOT main.
