Created /app/backend/tests/test_invoice_share_and_prefixes.py with 16 pytest cases — ALL 16 PASSED. Frontend public route /p/inv/{token}, /admin/invoice-share, and /admin/prefixes verified visually. Audit log captures user_email + IP for all mutating actions (create/lock/unlock/reset_series/archive) as required.",

    "invoice_share.py:157 — expires_at returned in issue_token is recomputed instead of using the stored value if a token was re-used (existing branch). Minor cosmetic — uses fresh now+expiry_days even when reusing an older token. Not a security issue (the stored expires_at is still authoritative), just an API response inconsistency. Consider returning existing['expires_at'] when reusing.",
    "invoice_share.py:444 — verify_url for non-custom-domain QR uses path-only '/api/invoice-share/public/{token}/verify'. When custom_domain is empty the QR has only a relative path which won't resolve when scanned. Recommend using request.base_url to build absolute URL for non-custom-domain QR as well.",
    "Both new files keep MongoDB ObjectId hidden from API responses correctly (_ser helper and _safe_invoice).",
