Defense Systems Route Recovery

Regression record for the /company/defense-systems HTTP 500 caused by an invalid Flask endpoint reference, including the canonical-route correction and a dependency-light route-contract guard.

Defense Systems Route Recovery

Release: 2.0.0-rc.19-WIP
Route: /company/defense-systems
Proof: 16 of 16 passed

The prior packaged template referenced the nonexistent Flask endpoint simulations.autonomous_drone_control; the simulations blueprint exposes the canonical page through simulations.detail(slug) instead. That stale endpoint reference could raise a Jinja/Werkzeug BuildError and return HTTP 500 before the page rendered. RC19 removes that reference and uses the stable root path /simulations/autonomous-drone-control.

The canonical Defense Systems route now attempts the complete Jinja surface first and emits X-Evulgare-Defense-Systems: full when successful. If a mixed or incomplete cPanel deployment lacks a template dependency or endpoint required by the shared base layout, the route logs the exception and returns a bounded standalone defense-capability surface with HTTP 200 and X-Evulgare-Defense-Systems: fallback.

The recovery surface is database-independent, accepts no customer content, exposes no operational interface, and exists to keep the defense-company front door available while a complete-root deployment is reconciled.

A complete-root deployment remains the required resolution. The fallback is not a substitute for package integrity.
