This is a packaging bug in TSP v0.3.3. The app/custom/* backend extension modules are discovered at runtime via importlib + pkgutil, which PyInstaller's static analysis cannot detect. The packaging/tsp.spec file was missing the datas + hiddenimports declarations for app/custom, so the assistant module was not bundled into the installer, its API routes were never registered, and requests fell through to the SPA catch-all GET route, returning 405.

Diagnosis clues:
- GET http://127.0.0.1:3018/api/custom/assistant/status returns HTML instead of JSON (route not registered)
- _internal/app/custom directory is missing from the install folder, while _internal/app/plugins/fuyao exists
- Other AI features (e.g., settings page connectivity check, post-market review) work normally

Fix: Upgrade to TSP v0.3.5 or later, where the spec file now includes the datas + hiddenimports declarations for app/custom. After upgrading, verify that _internal/app/custom/assistant exists in the installation directory. Download: https://github.com/shy3130/tick-stock-panel/releases/tag/v0.3.5

This was a bug: the custom data source pipeline never routed depth5. The dataset whitelist in config_from_dict() dropped depth5 at parse time, _sanitize_for_yaml() dropped it again when saving, the provider had no field contract or get_depth_batch() method for /depth5, and validate() wrongly treated depth5 as a date-range dataset requiring start/end params. It is fixed in commit 384094b (PR #479) — upgrade to a version containing that commit, then declare datasets.depth5 in your YAML and the panel's custom eltdx_source route will call the adapter's /depth5 endpoint. The fix (backend/app/data_providers/custom/): 1) config.py — add "depth5" to the DatasetName Literal and the datasets whitelist in config_from_dict(); 2) loader.py — add "depth5" to the allowlist in _sanitize_for_yaml(); 3) provider.py — add "depth5": {"symbol", "asks", "bids"} to _REQUIRED, exclude depth5 from the symbols/start/end duplicate-param check like realtime, and add GenericHTTPProvider.get_depth_batch() which chunks symbols by cfg.batch with rpm throttling, requests /depth5 with retry, skips failed batches with a warning, normalizes asks/bids price/volume to numbers, and derives ask_volumes/bid_volumes; 4) test_dataset() gets a depth5 branch that sends only test symbols without dates.
