0.6.0 — 2026-07-09

Upgrade notes for admins

Run the migration after pulling: docker compose run --rm backend python backend/manage.py migrate.
Rebuild and start the new ccc service: docker compose build ccc && docker compose up -d.
It bundles the semantic-search engine (a local sentence-transformers model — no
API key, no external DB); first build downloads the model and takes a few minutes.
New service URL wired in docker-compose.yml (CCC_SERVICE_URL=http://ccc:8004)
and a read-only ./sources/codebases mount on tdmcp and backend. No new
values needed in .env.
To add a local codebase: drop a folder under sources/codebases/<name>/ on the
server, then Console → Codebases → Add Codebase → Local and pick the folder.

Local codebases: Codebase now supports a local provider alongside
GitHub/GitLab. The agent reads files live from disk (no clone, no cached
tree) from a folder under sources/codebases/, gated by Role.allowed_codebases
exactly like remote codebases.
- Add Codebase gains a Local provider card; the form swaps the
  repository URL for a picker of unregistered folders under sources/codebases/
  (mirroring the docs "Register Folder" flow) and hides branch/token.
- The codebase MCP tools dispatch on provider: get_codebase_tree and
  read_codebase_file walk/read the mounted filesystem for local codebases;
  search_codebase uses ccc semantic search.
ccc service (containers/ccc/): a reusable, content-agnostic semantic-search
service — a FastAPI wrapper around cocoindex-code, following the same pattern as
the Codex/Claude gateways. Exposes POST /index and POST /search keyed by a
project path under sources/, so future consumers (e.g. documentation search)
can reuse it without changes.
Local codebases are indexed on registration and re-indexed periodically by a new
Celery-beat task (reindex_local_codebases, every 6h); the per-codebase Sync
button re-indexes on demand.

search_codebase and the codebase model docs now describe three providers
(GitHub, GitLab, local). repo_url is optional for local codebases.
