Lucas Gomide a237ebabba feat: adopt directory-based docs versioning with Edge channel (#6202)
* feat: adopt directory-based docs versioning with Edge channel

Switch docs.crewai.com from navigation-only versioning (every version
selector entry rendered the same docs/<lang>/* source files) to
Mintlify's directory-based versioning so each version selector entry
renders its own snapshot. Add an "Edge" channel under docs/edge/<lang>/*
that always reflects main HEAD for unreleased work, eliminating
pre-release leakage onto frozen release labels. External links to
canonical /<lang>/* URLs are preserved via wildcard redirects that
always land on the current default version.

Layout:
- docs/edge/<lang>/*         rolling source (you edit here)
- docs/edge/enterprise-api.*.yaml
- docs/v<X.Y.Z>/<lang>/*     frozen, immutable snapshots
- docs/v<X.Y.Z>/enterprise-api.*.yaml
- docs/images/               shared, append-only
- docs/docs.json             nav + redirects

URLs follow the Mintlify-idiomatic shape: /edge/<lang>/<page> for
Edge, /v<X.Y.Z>/<lang>/<page> for every frozen snapshot. The wildcard
redirects /<lang>/:slug* -> /<default>/<lang>/:slug* keep stale links
working, and every freeze rewrites them (plus all per-section/per-page
redirects) so destinations always resolve to the current default
without depending on a second redirect hop.

Release flow integration (devtools release):
- New module crewai_devtools.docs_versioning.freeze() materialises
  docs/v<X.Y.Z>/ from docs/edge/, rewrites openapi: refs inside the
  snapshot, inserts the version into every language block in
  docs.json, and refreshes all redirect destinations.
- _update_docs_and_create_pr() in cli.py now calls that freeze during
  Phase 2 of devtools release. Edge changelogs are updated first (so
  the snapshot freeze picks them up), then the snapshot is staged
  alongside docs.json, branched as docs/freeze-v<X.Y.Z>, and the PR
  is titled [docs-freeze] docs: snapshot and changelog for v<X.Y.Z>
  — the title prefix the new CI guard reads.
- The PR still gates tag, GitHub release, PyPI publish, and the
  enterprise release as before; no new PRs are added.
- Pre-releases (1.X.YaN, 1.X.YbN, ...) skip the snapshot — they ride
  Edge — and the docs PR title omits the [docs-freeze] prefix.
- docs_check (AI-generated docs scaffolding) writes to
  docs/edge/<lang>/* so newly-generated unreleased docs land in Edge
  and never accidentally touch a frozen snapshot.

Migration scripts (one-shot):
- scripts/docs/freeze_historical_versions.py reconstructs all 16
  historical snapshots (v1.10.0 .. v1.14.7) from git tags via
  git archive | tar, rewriting openapi: MDX refs so each snapshot
  reads its own enterprise-api YAML rather than the live one.
- scripts/docs/prefix_version_paths.py one-shot-migrates docs.json:
  rewrites every page path in 16 versioned blocks to point under
  docs/v<X.Y.Z>/, inserts a new Edge entry per language, tags
  v1.14.7 as Latest (default), prunes pages whose target file
  doesn't exist in the snapshot (e.g. docs/ar/ didn't exist before
  v1.12.0), and writes the wildcard + per-section redirects.
- scripts/docs/freeze_current_edge.py is now a thin CLI wrapper
  around docs_versioning.freeze for manual one-off freezes (e.g.
  retroactively snapshotting a forgotten release).

CI guards (.github/workflows/docs-snapshots.yml):
- Frozen snapshots under docs/v[0-9]*/ are immutable; only PRs whose
  title contains [docs-freeze] (i.e. release-cut PRs generated by
  devtools release or the manual wrapper) may modify them.
- Images under docs/images/ are append-only since snapshots share a
  single image directory. Deleting or renaming an image breaks every
  historical snapshot that still references it.

Restored docs/images/crewai-otel-export.png from PR #3673; it was
deleted in PR #4908 but v1.10.0 / v1.10.1 snapshots still reference
it. Restoring instead of editing the snapshots preserves historical
rendering fidelity and validates the new append-only rule
retroactively.

Tests:
- lib/devtools/tests/test_docs_versioning.py covers the freeze: file
  copy, openapi rewrite, version insertion, default demotion, redirect
  upserts, per-section redirect rewriting, idempotency, and invalid
  inputs.

Verified locally with mintlify broken-links: 0 broken links across
the full site (Edge + 16 frozen versions, 4 locales).

AGENTS.md (repo root) is the contributor guide for the new model;
RELEASING.md is the release-cut runbook; README's Contribution
section links to both.

<Steps>
<Step title="LangDB 설치">
CrewAI 기능 플래그와 함께 LangDB 클라이언트를 설치하세요:
```bash
pip install 'pylangdb[crewai]'
```
</Step>
<Step title="환경 변수 설정">
LangDB 자격 증명을 구성하세요:

</Step>
<Step title="추적(Tracing) 초기화">
CrewAI 코드를 설정하기 전에 LangDB를 임포트하고 초기화하세요:
```python
from pylangdb.crewai import init
# Initialize LangDB
init()
```
</Step>
<Step title="CrewAI와 LangDB 연동 설정">
LangDB 헤더와 함께 LLM을 설정하세요:
```python
from crewai import Agent, Task, Crew, LLM
import os
# Configure LLM with LangDB headers
llm = LLM(
model="openai/gpt-4o", # Replace with the model you want to use
api_key=os.getenv("LANGDB_API_KEY"),
base_url=os.getenv("LANGDB_API_BASE_URL"),
extra_headers={"x-project-id": os.getenv("LANGDB_PROJECT_ID")}
)
```
</Step>
</Steps>
## 빠른 시작 예제
여기 LangDB와 CrewAI를 시작하는 간단한 예제가 있습니다:
```python
import os
from pylangdb.crewai import init
from crewai import Agent, Task, Crew, LLM
# Initialize LangDB before any CrewAI imports
init()
def create_llm(model):
return LLM(
model=model,

이 가이드에서는 LangDB AI Gateway를 CrewAI와 통합하는 기본 사항을 다루었습니다. AI 워크플로우를 더욱 강화하려면 다음을 탐색해보세요:
- **Virtual Models**: 라우팅 전략을 사용한 맞춤형 모델 구성 만들기
- **Guardrails & Safety**: 콘텐츠 필터링 및 컴플라이언스 제어 구현
- **Production Deployment**: 폴백, 재시도, 로드 밸런싱 구성
보다 고급 기능 및 사용 사례에 대해서는 [LangDB Documentation](https://docs.langdb.ai)을 방문하거나, [Model Catalog](https://app.langdb.ai/models)를 탐색하여 사용 가능한 모든 모델을 확인해 보세요.
