Context-envelope publication summary

Status: 160K/C1 is a qualified reference profile on the measured RTX 5090. Deployment state is private.

The direct-I/O profile passed preflight 8/8, vision 18/18, repeated bounded quality, depth retrieval 9/9 and unique-canary capacity (short 12/12; long 3/3). Maximum retained input was 150,144 tokens with an 8,192-token output allowance. Long-capacity GPU free floor was 4,598 MiB. Earlier 64K measurements remain a separate comparison.

Claim	Evidence	Limit
Preflight 8/8	native result	Direct endpoint
Depth retrieval 9/9	native result	Three fixed workloads; first cold/partial-cache, later warm
Long capacity 3/3	native result	Descriptive n=3; no endurance or matched speed claim
Native client compatibility	summary	Bounded tool probes; macOS shell-marker limitation retained

Short copy: The measured 160K/C1 profile passed bounded correctness and capacity checks with about 4.5 GiB GPU free. The output allowance is a request cap, not an observed generated-length result.
