# FIX Antenna .NET: original receiver-thread placement qualified

Both hosts complete eighteen new native cases, fourteen actual invalid CLI
profiles, 288 altered actual-output refusals and independent cold collection.
Each checks 2,480 original application frames, 552 captured unmeasured frames,
962 primary spans, 576 measured primary and 480 measured scheduler-delay values.
HP retains 254 administrative frames; SCAN retains 252. Twelve prefix cycles
per pair and all 170 warmup/prewarm values are excluded from measured series.
Application capture closes before warmup, with zero measured frame copies.
No timing, physical improvement or result admission follows from finite proof.

The separately named consumer changes only receiver placement and its proof.
It uses the original SDK's existing public raw receive callback, pins its thread
on the first unmeasured application frame and verifies the identical native
thread/CPU at original Logout. It first reads that thread's complete inherited
mask and refuses a target outside it. The original measurement CPU is retained:
HP server/client measure on 8/13 and receive on 9/14; SCAN measure on 10/14 and
receive on 11/15. Complete thread identities, initial masks, first-marker/closure
and final Logout timestamps are independently checked. Every later application
callback must use the same original managed thread. Native CPU masks verify the
actual normal-user OS affinity call rather than relying on the SDK option's
physical-ID versus ProcessorCount validation.

The protected business/public-send, callback/clock and shared-task source bodies
match the completed report source byte for byte. Its unmodified original SDK,
fixed-scale writer and shared harness are not rebuilt. The new producer compiles
alone without warnings. All 73 focused placement/inherited-source controls pass
without selected skips. The source privacy scan has zero findings. No SDK patch,
processor-count override, custom transport, root helper/sudo or old configuration
change is made. The SDK-envelope prepared-application tick limitation stays
explicit and cannot be promoted by receiver placement.

The separate immutable receiver package and fixed-entry reader have 144 passing
source controls, including actual launcher refusals, payload/mode/source binding,
parsed invocation and receiver-policy provenance. Both native independent reviews
and their 288 actual corruptions are mandatory before packaging. Installation,
sixteen relocated/fixed-DAC cases and any subsequent separately named quiet DAC
campaign remain pending at this checkpoint. Existing failed physical matrices
are complete and are not repeated unchanged.

Both `codex-fullbench-fixantenna-receiver-20261026-v1.service` units exit
successfully under functional isolated leases, at high priority on HP and
normal priority on SCAN. All original working output stays under
`~/build/codex-fullbench/libhft/fixantenna-receiver-qualification-20261026-v1`
on its host. Independent complete copies and hash inventories are under
`~/build/codex-fullbench/libhft/fixantenna-receiver-review-20261026-v1/{hp,scan}`.
The source hypothesis and original failed timing gates remain in the
[CPU investigation](RECORD_2026-10-26_fixantenna_measured_cpu.md) and
[completed physical campaign](RECORD_2026-10-26_fixantenna_physical.md).


## Immutable entry qualification

Both source-specific immutable generations subsequently pass sixteen native
and independently replayed deployment pairs per host: eight relocated local
pairs and eight through the fixed physical DAC entry. The installed source is
`2fe19e1c7acd6e6c71b379ab166118cbb4ab2915`. Each binds all thirteen payload
files/modes, actual loaded original SDK/helper/harness, normal UID, CPU/namespace
placement, parsed invocation and the complete original receiver-thread proof.
No SDK/producer/harness or root-helper/sudo change is made.

The separately named physical/admission controller passes fifty focused controls,
retaining the original full report gates and explicit tick-envelope blocker,
with strict receiver-policy/CPU provenance. Fresh quiet physical execution and
its independent 107-corruption replay remain pending; source/deployment proof
creates no timing-grade cell.
