# Production roadmap: from loop output to shipped product

**Status:** synthesis — every loop finding mapped to a concrete next-step action · **2026-05-22**

## Why this document exists

The SOTA research loop produced 34+ ticks of physics, simulation, architecture, and vertical sketches. Without a roadmap, none of it ships. This document maps every loop output to:

- **Owner** (which team / role picks it up)
- **LOC estimate** (rough engineering cost)
- **Dependencies** (what must land first)
- **Priority** (HIGH/MEDIUM/LOW based on leverage × certainty)

Reading order: top sections are the highest-leverage / shortest-path-to-ship items. Bottom sections are exotic / long-horizon work.

## Tier 1 — Ship in next quarter (Q3 2026)

### 1.1 — `wifi-densepose plan-antennas` CLI tool

**LOC**: ~360 (placement search engine, 4-axis matrix lookup, 3D ellipsoid extension, multi-target union)
**Dependencies**: none (reference numpy implementations exist in examples/research-sota/)
**Priority**: **HIGH** — 93× sensing-coverage lift from physics alone; existing customers can re-mount today

## Total engineering budget across the loop's output

| Tier | LOC | Person-weeks |
|---|---:|---:|
| Tier 1 (Q3 2026) | ~490 | 3-4 |
| Tier 2 (Q3-Q4 2026) | ~1180 | 6-8 |
| Tier 3 (2027) | ~1140 | 8-10 |
| Tier 4-5 (long horizon) | ~700+ | 6-8 |
| **Total** | **~3,500 LOC** | **~25 person-weeks** |

This includes both the privacy + federation + PQC chain (~1,820 LOC) and the placement / cog / integration work (~1,700 LOC).

## What this roadmap DOES enable

1. **A team can pick this up and start shipping** without re-reading the 34 research notes.
2. **Priority alignment** for engineering managers.
3. **Estimate-anchoring** for project planning.
4. **Critical-path visibility** for parallel work scheduling.

## What this roadmap DOES NOT enable

- Production validation (still required per Tier 2.3 bench validation).
- Regulatory approval (Tier 6.3 separate pathway).
- Partnership establishment (Tier 4.4 / 4.3 / 5.4 all need external partners).
- The roadmap is **only as good as the underlying ticks** — synthetic-data-based estimates may shift.

## Composes with every loop thread

This document is the **terminal output** of the loop — every research thread, ADR, vertical sketch, and follow-up has a line in some Tier above.

## Connection back

Every loop output → roadmap line:
- Research threads R1, R3, R5–R18 → Tier 3-5 cogs + Tier 1-2 implementations
- ADRs 105-109 + 113 → Tier 2-4 implementation work
- R6 family (9 ticks) → Tier 1.1 CLI + Tier 4.4 production multi-scatterer
- R3 arc (3 ticks) → Tier 3.3 real-AETHER + Tier 3 cross-room re-ID
- R12 arc (3 ticks) → Tier 1.2 R12.1 pose-PABS + Tier 3.4 cog-fall-detection
- Negative results (R12 revisited, R13 floor, R3.1 architecture) → Tier 5 research-needed items
- Honest-scope findings → Tier 5 research-needed items
