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.

Added

• 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.

Changed

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

Fixed

• refresh_single_chart and send_report_email_task logged their (string,
  prefixed-ULID) primary keys with %d instead of %s. Chart/report data was
  never affected, but every successful chart refresh spammed the celery worker
  log with a spurious --- Logging error --- traceback, and — worse — a real
  refresh failure would hit the same bug in the except block, throwing away
  the actual error message before it could be logged.
