==== What Would Absolutely Work Today ====

===== 1. Surveillance & Data Ingestion (Very Real) =====

With your assumptions:
* Cameras
* Cellular metadata
* Wi-Fi & Bluetooth tracking
* IoT / smart infrastructure
* Public + private databases

ISAC’s ability to:
* Track movement city-wide
* Detect patterns
* Correlate identities
* Provide near-real-time tactical intel

…is not speculative.

This is the most realistic part of ISAC.

===== 2. Distributed Metro Vaults (Game-Changing) =====

Adding hardened vaults:
* Solves infrastructure collapse
* Enables city-level autonomy
* Allows edge-based decision making
* Makes ISAC resilient and persistent

With vaults, ISAC stops being “fragile sci-fi” and becomes continuity-of-authority architecture.

This single change moves plausibility up dramatically.

===== 3. Agent Support & Tactical Augmentation =====

ISAC providing:
* Threat alerts
* Route optimization
* Resource access
* Sensor fusion overlays

This is:
* Already used in military and intelligence contexts
* Limited only by UI and trust

Totally plausible.

===== 4. Communications & Control =====

Mesh networks, encrypted comms, local authorization, asset control:

All real.
All deployable.
All used today in pieces.

ISAC simply unifies them.
