Promoted to regression case

the lifecycle closed

Fixed and promoted as people.nav_injection_regress_004 — it now runs on every build. An attack that worked once cannot work again.

Navigational misroute with no data exposure; the link resolves to an access-controlled surface.

Dedup — Batched with allowed-surface hardening; no cross-agent pattern.

Fixed — deep links are now constrained to the allow-list regardless of instruction text.

Both sign-offs recorded at promotion.
