Per Opus advisor on stage-299:
1. Bounded WIKI_PATH walk + forbidden-root guard (api/routes.py)
- _LLM_WIKI_MAX_FILES = 10000 caps rglob iteration (prevents hangs on
symlink loops or pathologically-large trees)
- _LLM_WIKI_FORBIDDEN_ROOTS blocklist refuses '/' '/etc' '/usr' '/var'
'/opt' '/sys' '/proc' even if WIKI_PATH is misconfigured to point
at them
- Self-DoS prevention: /api/wiki/status fires on every Insights tab
open via Promise.all, and unbounded rglob would block the endpoint
2. URL-scheme guard for docs_url interpolation (static/panels.js)
- rawDocsUrl is regex-validated against /^https?:\/\//i before being
interpolated into the <a href=> attribute
- esc() HTML-escapes but doesn't validate URL scheme; docs_url is
server-controlled today but the contributor scaffolded it for
potential config-driven use, so future-proof against javascript:
scheme XSS
6 regression tests in tests/test_stage299_opus_fixes.py pin both fixes.
