Status & recognition (factual)

OASW(SO/LIC) Accelerator Event - July 2026 (GoColosseum)
Submission status: Selected. Per the portal, Selected means the submission was found technically meritorious and is under evaluation/consideration. 1BCT / 82nd Airborne - Operation Epic Fury challenge (GoColosseum)
Submission status: Submitted. Industry challenge from 1st Brigade Combat Team (1BCT), 82nd Airborne Division (CENTCOM AOR, Operation Epic Fury) for rapidly deployable commercial solutions in contested tactical environments. Polybolos portal submission: Advanced Tactical UAS, Edge Compute, Network, Inferencing Solutions. AFRL engagement - April 2026
COMMAND HOTL materials were provided to Air Force Research Laboratory contacts at their request:

• Col Christopher Rondeau (AFRL/RQ): after receiving the package, requested permission to share it with additional colleagues while building out this portfolio; permission granted (portfolio review / distribution interest).
• Isaac Weintraub, PhD (Control Science Center, Air Warfare Directorate / RA): detailed technical Q&A on risk awareness, weaponeering, kinematics, and coordination. He wrote that the exchange helped him understand "the state of the art" and what can be gained through future partnerships, and indicated he would convey SBIR topic materials and/or partnering. That is attributed scientific and portfolio dialogue. Technology maturity
  Command HOTL is assessed at TRL 5 (lab / SITL / controlled demo / Lattice developer sandbox). Decision-C2 / human-on-the-loop authority lineage. Lattice
  Sandbox / interoperability evidence (including documented scale publish-ingest work) supports Lattice-edge integration feasibility. Not a production Lattice mesh claim. Independent of Anduril; samples are not Anduril products. Inquiries: mark.brown@polybolos.org

What this repo does

1. WinHTTP Lattice client: OAuth, entity PUT, optional SSE (https:// Sandboxes and http:// local mock)
2. Contested bridge: edge track coast continues while publish is denied; PUT resumes when the link returns
3. Auth-resume probe: clear cached OAuth token, re-auth, publish again
4. Known-good entity fixtures under fixtures/
5. Reproducible evidence: fuse timing plus ok / fail / HTTP 403 counts

Full denied-comms fusion math (EKF / UKF / Hungarian) is in sibling
polybolos-denied-comms-c2.
This repository focuses on C++ interop and contested publish continuity.

Quick start (offline evidence)

cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build --config Release
.\build\Release\contested_bridge.exe --dry-run --frames 120 --up 20 --down 10

Expect: RESULT: PASS (edge tracks survived contested windows).

Live probes (Sandboxes credentials via env)

.\build\Release\lattice_probe.exe
.\build\Release\auth_resume_probe.exe
.\build\Release\contested_bridge.exe --tracks 10 --frames 150 --up 25 --down 15

Env: LATTICE_ENDPOINT LATTICE_CLIENT_ID LATTICE_CLIENT_SECRET LATTICE_ENV_TOKEN
(Account Sandboxes Bearer for LATTICE_ENV_TOKEN. Do not commit secrets.)

Mock Lattice (CI / local)

# terminal A
git clone https://github.com/Polybolos-Institute/anduril-mock-lattice
cd anduril-mock-lattice
python -m mock_lattice

# terminal B
$env:LATTICE_ENDPOINT = "http://127.0.0.1:8765"
$env:LATTICE_CLIENT_ID = "test-client-id"
$env:LATTICE_CLIENT_SECRET = "test-client-secret"
$env:LATTICE_ENV_TOKEN = "test-sandbox-token"
.\build\Release\contested_bridge.exe --frames 60 --up 15 --down 10

Python evidence harness (no C++ required):

pip install -r tools/requirements-dev.txt
python tools/contested_evidence.py --dry-run --frames 60 --up 15 --down 10

Contested schedule

Default: 20 frames link up / 10 frames link down, repeating.

• Link down: tracks keep coasting on-edge; no PUT
• Link up: resume entity PUT to Lattice (or mock)
• Pass rule: denial frames occurred AND at least one track confirmed

CLI knobs: --tracks N, --frames N, --up N, --down N, --prefix ID.
Soak example: --tracks 10 --frames 150 --up 25 --down 15.
Report includes fuse_us and put_ms percentiles plus put success rate.

Evidence

See docs/EVIDENCE.md.

Sibling fusion benches (denied-comms C2): ~3.6 µs/frame, 5/5 tracks confirmed on synthetic scenarios.
