PR #569: Fix bug_checker.py syntax error (missing try-block indent)

[jaayslaughter-cpu]

PR #569 — Hotfix: bug_checker.py syntax error

Root cause

3 consecutive Railway deploy failures since PR #566:

File "/app/bug_checker.py", line 21
    from railway_log_scanner import (
    ^^^^
SyntaxError: expected 'except' or 'finally' block

The from railway_log_scanner import line was missing 4-space indent inside the try: block (layer_coverage_check + railway_log_scanner should both be inside the same try).

Fix

Add missing indentation — both imports now inside the try block.

Note

Service has been running on the last successful build (pre-PR #566 content). bp2vec and XGB retrain were triggered successfully against that build. The walkforward endpoint from PR #568 will activate once this deploys.

Summary by cubic

Fixes a syntax error in bug_checker.py by properly indenting the railway_log_scanner import inside the try block, so it’s grouped with layer_coverage_check. This resolves the deploy failures on Railway.

Code Review

This pull request fixes an indentation error in bug_checker.py to ensure imports are correctly contained within a try block. Feedback indicates that this change may cause a regression because the corresponding except block lacks a fallback for the newly grouped imports, potentially leading to a NameError during execution. Additionally, an unused import was identified.

[gemini-code-assist]

While this change correctly fixes the syntax error, grouping these imports into a single try block without updating the corresponding except ImportError block (line 25) introduces a regression.

If layer_coverage_check.py is missing, the ImportError will be caught, but the except block does not provide a fallback for _check_layer_coverage. This will cause a NameError when the function is called at line 538. Furthermore, the existing fallback messages specifically mention railway_log_scanner.py, which would be misleading if the failure was caused by layer_coverage_check.py.

Recommendation: Update the except block to provide a fallback for _check_layer_coverage and ensure the error messages are accurate. Additionally, format_layer_embed (imported on line 20) appears to be unused in this file.
