Added new model backup layer JSON files (risks, policies, workflows, infra metadata) and updated layer-count documentation.
Introduced a multi-tier cache module (api/cache/*) with Redis client, cache layer, invalidation manager, and FastAPI integration helpers.
Added/updated session bootstrap + status docs and included several local/debug utility scripts and artifacts.

Redis operations are invoked without await. In this PR, RedisClient methods are async, so calling them sync will return coroutine objects, causing cache hits/misses and invalidations to behave incorrectly (and may log runtime warnings). Update RedisCache to await RedisClient calls (get/setex/delete/keys/info) or refactor RedisCache to use a synchronous Redis client consistently.

Suggested change

"""Invalidate key across all cache layers"""

"""Invalidate key across all cache layers.

This method ensures that a given key is removed from every configured

cache layer (L1 and L2). The source of truth (L3 / Cosmos) is not

modified here; callers are responsible for updating or deleting data

in the backing store first, then invalidating the caches.

The example below demonstrates the full multi-tier behaviour:

- Initial request falls through L1 and L2 to L3.

- L3 result is cached into both L1 and L2.

- Subsequent request is served from L1 (memory) only.

- Invalidation removes the key from L1 and L2; the next lookup misses.

The async scenario can be exercised with doctest (or pytest's doctest

plugin) as follows:

>>> import asyncio

>>>

>>> async def _demo_roundtrip():

... # L1, L2, and L3 are all simple in-memory caches for this demo

... l1 = MemoryCache()

... l2 = MemoryCache()

... l3 = MemoryCache()

...

... cache = MultiTierCache(l1=l1, l2=l2, l3=l3)

...

... # Populate only L3; L1 and L2 start empty

... await l3.set("demo-key", {"value": 42}, ttl_seconds=60)

...

... # First get: L1 miss, L2 miss, L3 hit → backfill L1 and L2

... value1 = await cache.get("demo-key")

... assert value1 == {"value": 42}

...

... # L1 now has the value; this is served from memory without

... # touching L2 or L3.

... value2 = await cache.get("demo-key")

... assert value2 == {"value": 42}

...

... # Invalidate the key across cache layers

... deleted = await cache.invalidate("demo-key")

... assert deleted is True

...

... # After invalidation, all cache layers miss on this key

... assert await l1.get("demo-key") is None

... assert await l2.get("demo-key") is None

... # cache.get(...) will miss and return None because L3 has not

... # been repopulated

... value3 = await cache.get("demo-key")

... assert value3 is None

...

>>> asyncio.run(_demo_roundtrip())
