* refactor: extract shared skill installer and upload manager to harness
Move duplicated business logic from Gateway routers and Client into
shared harness modules, eliminating code duplication.
New shared modules:
- deerflow.skills.installer: 6 functions (zip security, extraction, install)
- deerflow.uploads.manager: 7 functions (normalize, deduplicate, validate,
list, delete, get_uploads_dir, ensure_uploads_dir)
Key improvements:
- SkillAlreadyExistsError replaces stringly-typed 409 status routing
- normalize_filename rejects backslash-containing filenames
- Read paths (list/delete) no longer mkdir via get_uploads_dir
- Write paths use ensure_uploads_dir for explicit directory creation
- list_files_in_dir does stat inside scandir context (no re-stat)
- install_skill_from_archive uses single is_file() check (one syscall)
- Fix agent config key not reset on update_mcp_config/update_skill
Tests: 42 new (22 installer + 20 upload manager) + client hardening
* refactor: centralize upload URL construction and clean up installer
- Extract upload_virtual_path(), upload_artifact_url(), enrich_file_listing()
into shared manager.py, eliminating 6 duplicated URL constructions across
Gateway router and Client
- Derive all upload URLs from VIRTUAL_PATH_PREFIX constant instead of
hardcoded "mnt/user-data/uploads" strings
- Eliminate TOCTOU pre-checks and double file read in installer — single
ZipFile() open with exception handling replaces is_file() + is_zipfile()
+ ZipFile() sequence
- Add missing re-exports: ensure_uploads_dir in uploads/__init__.py,
SkillAlreadyExistsError in skills/__init__.py
- Remove redundant .lower() on already-lowercase CONVERTIBLE_EXTENSIONS
- Hoist sandbox_uploads_dir(thread_id) before loop in uploads router
* fix: add input validation for thread_id and filename length
- Reject thread_id containing unsafe filesystem characters (only allow
alphanumeric, hyphens, underscores, dots) — prevents 500 on inputs
like <script> or shell metacharacters
- Reject filenames longer than 255 bytes (OS limit) in normalize_filename
- Gateway upload router maps ValueError to 400 for invalid thread_id
* fix: address PR review — symlink safety, input validation coverage, error ordering
- list_files_in_dir: use follow_symlinks=False to prevent symlink metadata
leakage; check is_dir() instead of exists() for non-directory paths
- install_skill_from_archive: restore is_file() pre-check before extension
validation so error messages match the documented exception contract
- validate_thread_id: move from ensure_uploads_dir to get_uploads_dir so
all entry points (upload/list/delete) are protected
- delete_uploaded_file: catch ValueError from thread_id validation (was 500)
- requires_llm marker: also skip when OPENAI_API_KEY is unset
- e2e fixture: update TitleMiddleware exclusion comment (kept filtering —
middleware triggers extra LLM calls that add non-determinism to tests)
* chore: revert uv.lock to main — no dependency changes in this PR
* fix: use monkeypatch for global config in e2e fixture to prevent test pollution
The e2e_env fixture was calling set_title_config() and
set_summarization_config() directly, which mutated global singletons
without automatic cleanup. When pytest ran test_client_e2e.py before
test_title_middleware_core_logic.py, the leaked enabled=False caused
5 title tests to fail in CI.
Switched to monkeypatch.setattr on the module-level private variables
so pytest restores the originals after each test.
* fix: address code review — URL encoding, API consistency, test isolation
- upload_artifact_url: percent-encode filename to handle spaces/#/?
- deduplicate_filename: mutate seen set in place (caller no longer
needs manual .add() — less error-prone API)
- list_files_in_dir: document that size is int, enrich stringifies
- e2e fixture: monkeypatch _app_config instead of set_app_config()
to prevent global singleton pollution (same pattern as title/summarization fix)
- _make_e2e_config: read LLM connection details from env vars so
external contributors can override defaults
- Update tests to match new deduplicate_filename contract
* docs: rewrite RFC in English and add alternatives/breaking changes sections
* fix: address code review feedback on PR #1202
- Rename deduplicate_filename to claim_unique_filename to make
the in-place set mutation explicit in the function name
- Replace PermissionError with PathTraversalError(ValueError) for
path traversal detection — malformed input is 400, not 403
* fix: set _app_config_is_custom in e2e test fixture to prevent config.yaml lookup in CI

* fix(threads): clean up local thread data after thread deletion
Delete DeerFlow-managed thread directories after the web UI removes a LangGraph thread.
This keeps local thread data in sync with conversation deletion and adds regression coverage for the cleanup flow.
* fix(threads): address thread cleanup review feedback
Encode thread cleanup URLs in the web client, keep cache updates explicit when no thread search data is cached, and return a generic 500 response from the cleanup endpoint while documenting the sanitized error behavior.

This PR improves MiniMax Code Plan integration in DeerFlow by fixing three issues in the current flow: stream errors were not clearly surfaced in the UI, the frontend could not display the actual provider model ID, and MiniMax reasoning output could leak into final assistant content as inline <think>...</think>. The change adds a MiniMax-specific adapter, exposes real model IDs end-to-end, and adds a frontend fallback for historical messages.

* feat(manager): add bootstrap command to initialize soul.md in correct place
* feat(channels): add /bootstrap command to IM channels
Add a `/bootstrap` command that routes to the chat handler with
`is_bootstrap: True` in the run context, allowing the agent to invoke
its setup/initialization flow (e.g. `setup_agent`).
- The text after `/bootstrap` is forwarded as the chat message; when
omitted a default "Initialize workspace" message is used.
- Feishu channels use the streaming path as with normal chat.
- No changes to ChannelStore — bootstrap is stateless and triggered
purely by the command.
- Update /help output to include /bootstrap.
- Add 5 tests covering: text/no-text variants, Feishu streaming path,
thread creation, and help text.

* refactor: extract shared utils to break harness→app cross-layer imports
Move _validate_skill_frontmatter to src/skills/validation.py and
CONVERTIBLE_EXTENSIONS + convert_file_to_markdown to src/utils/file_conversion.py.
This eliminates the two reverse dependencies from client.py (harness layer)
into gateway/routers/ (app layer), preparing for the harness/app package split.

* refactor: split backend/src into harness (deerflow.*) and app (app.*)
Physically split the monolithic backend/src/ package into two layers:
- **Harness** (`packages/harness/deerflow/`): publishable agent framework
package with import prefix `deerflow.*`. Contains agents, sandbox, tools,
models, MCP, skills, config, and all core infrastructure.
- **App** (`app/`): unpublished application code with import prefix `app.*`.
Contains gateway (FastAPI REST API) and channels (IM integrations).
Key changes:
- Move 13 harness modules to packages/harness/deerflow/ via git mv
- Move gateway + channels to app/ via git mv
- Rename all imports: src.* → deerflow.* (harness) / app.* (app layer)
- Set up uv workspace with deerflow-harness as workspace member
- Update langgraph.json, config.example.yaml, all scripts, Docker files
- Add build-system (hatchling) to harness pyproject.toml
- Add PYTHONPATH=. to gateway startup commands for app.* resolution
- Update ruff.toml with known-first-party for import sorting
- Update all documentation to reflect new directory structure
Boundary rule enforced: harness code never imports from app.
All 429 tests pass. Lint clean.

* chore: add harness→app boundary check test and update docs
Add test_harness_boundary.py that scans all Python files in
packages/harness/deerflow/ and fails if any `from app.*` or
`import app.*` statement is found. This enforces the architectural
rule that the harness layer never depends on the app layer.
Update CLAUDE.md to document the harness/app split architecture,
import conventions, and the boundary enforcement test.

* feat: add config versioning with auto-upgrade on startup
When config.example.yaml schema changes, developers' local config.yaml
files can silently become outdated. This adds a config_version field and
auto-upgrade mechanism so breaking changes (like src.* → deerflow.*
renames) are applied automatically before services start.
- Add config_version: 1 to config.example.yaml
- Add startup version check warning in AppConfig.from_file()
- Add scripts/config-upgrade.sh with migration registry for value replacements
- Add `make config-upgrade` target
- Auto-run config-upgrade in serve.sh and start-daemon.sh before starting services
- Add config error hints in service failure messages

* fix: handle empty config and search parent dirs for config.example.yaml
Address Copilot review comments on PR #1131:
- Guard against yaml.safe_load() returning None for empty config files
- Search parent directories for config.example.yaml instead of only
looking next to config.yaml, fixing detection in common setups

* fix: correct skills root path depth and config_version type coercion
- loader.py: fix get_skills_root_path() to use 5 parent levels (was 3)
after harness split, file lives at packages/harness/deerflow/skills/
so parent×3 resolved to backend/packages/harness/ instead of backend/
- app_config.py: coerce config_version to int() before comparison in
_check_config_version() to prevent TypeError when YAML stores value
as string (e.g. config_version: "1")
- tests: add regression tests for both fixes
