# Eight-Cell Product Cap Promotion

**A — PROMOTED — READY FOR 0.12.0 RELEASE. Normal product cap: 8.**

The selected-network product maximum is promoted from6 to8 in the canonical policy and normal Go/React/OpenAPI builds. Recommendation remains5, Measurement Validation remains6. The frontend Recommendation guard uses its independent constant; request builders/persistence guards and bounded-follow-up accounting are preserved.

Qualification remains the exact eight frozen paired Ankara2026.07 W1 layouts at2.6/28GHz,120rays/400m/30dBm/120deg/legacy two-pass, shipping Go1.26.6 Linux/arm64 CGO0/cgroupv2 Profile A2CPU/4GiB. No W2/W3, arbitrary hardware/datasets or multi-instance extrapolation.

## Promotion and accounting

Normal Evaluate/Optimize/Interference/Building Entry/Explanation accept8/reject9. Normal Auto reports8 without adaptive behavior. No source-copy cap patch or environment switch is used. Historical audit binaries/reports retain their original six-cap context.

| Eight-Cell journey | Ordinary | Extra |
|---|---:|---:|
|Evaluate/maps|1|8|
|Optimize/maps|1|8|
|Full cycle|11|8|
|Evaluate→Optimize/maps|10|8|
|Cycle→Optimize/maps (F28)|20|8|

All16 frozen F28 cases succeed;448 required RF calls. Worst `11.788444160s`, minimum headroom `48.211555840s`, process kernel peak `1217204224` bytes, OOM/kill/max0. The matrix completed before an additional scientific probe failed because it omitted a historically included optimization field; retained completed HTTP rows were independently verified, and corrected supplemental comparisons passed. No failed probe substitutes for evidence.

Exact eight-Cell JSON outputs match800 frozen audit-eight baseline responses;32 Explanation/Building Entry comparisons match historical evidence, excluding only the pre-existing volatile Building Entry diagnostics.elapsed_ms. Search still proposes578 legacy states. Distinct-IP Optimize+Optimize, Optimize+Evaluate and Evaluate+Evaluate overlap; qualified async/sustained interval, producer/drain and final-tail guards pass. Real cancellation and budget/replay/forgery checks retain the validated policy behavior.

## Product presentation and persistence

Actual normal eight-Cell F28 browser test passes; numbered badges1..8 render. App interaction tests refuse a ninth without RF and retain selection. Eight responsive light/dark presentation tests cover normal Setup/list/scrolling, with RF mocked only for presentation. The actual F28 test opens Review Results and Solutions, verifies eight per-Cell rows and scrolls to the last row. Reports retain all eight IDs. Eight network-result-only projects round-trip; larger ray-bearing projects can still reach existing guards at either cardinality. These guards and schemas remain unchanged.

## Release and historical evidence

All promotion gates pass. Canonical VERSION and package-visible references are0.12.0. The final normal shipping image completes F28, matches28 frozen outputs and rejects the next unrelated request. No tag/release/push is performed here. W1 qualification, invalid/valid audits, design and policy implementation studies are hash-preserved. New tooling builds normal cap8; historical cap-only audit mechanisms remain immutable history.
