# Dome Lab public release record Initial publication date: 2026-08-31 EC Parts Builder lib-6.1 update: 2026-09-04 Research-paper revision: 2026-09-04 Force Curve Bench fc-3.5 update: 2026-09-04 Repository: This record identifies the public Dome Lab system after the Force Curve Bench, EC Parts Builder, storefront pages, and Preprint 2.1 were released, including the subsequent EC Parts Builder lib-6.1 and Force Curve Bench fc-3.5 updates. It does not replace the tool-specific manifests or the frozen research record. ## Public entry points - [Dome Lab](https://unrealkeyboards.com/pages/dome-lab) — public hub. - [Force Curve Bench](https://unrealkeyboards.com/pages/topre-force-curve-library) — Shopify presentation of `fc-3.5`. - [EC Parts Builder](https://unrealkeyboards.com/pages/topre-ec-parts-library-builder) — Shopify presentation of `lib-6.1`. - [Beyond Snap Ratio](https://unrealkeyboards.com/pages/beyond-snap-ratio) — preprint overview and download links. - [Topre & EC Dome Force Curves](https://unrealkeyboards.com/blogs/topre-mods/topre-dome-force-curves) — public explanatory article. The standalone tools remain available at: - - ## Released identities | Artifact | Public identity | |---|---| | Force Curve Bench | `fc-3.5`; Git tag `fc-3.5` | | EC Parts Builder | `lib-6.1`; Git tag `ec-parts-lib-6.1` | | Previous EC Parts Builder | `lib-6.0`; Git tag `ec-parts-lib-6.0`; release commit `134e0c2` | | Frozen raw-source commit | `6e86ac1955a0c566c7aae521705e51371992ba8a` | | Canonical evidence identity | `7aa8588b50856816b7fce90dd6e743c26c6f16926071123291cb054352b6cd4a` | | Measurement method | `metrics-v4.2` | | Intake authority | `intake-qc-v1.4`, implementation-parity bound to `test-imp 1.1.4` | | Dome testing SOP | `dome-testing-sop-v1`; frozen operator intake and new-dome release gates | | Perception-index model | `perception-rank-v1` | | Active site authority | `SITE_RELEASE_MANIFEST.json` and `SHA256SUMS` | | Protected predecessor authority | `FORCE_CURVE_BENCH_RELEASE_MANIFEST.json` | `SITE_RELEASE_MANIFEST.json` inventories every released repository path and its SHA-256 digest. `FORCE_CURVE_BENCH_RELEASE_MANIFEST_fc-3.5.json` records the current viewer overlay. The original Force Curve Bench manifest remains in the site package as the immutable fc-3.4 predecessor record. The lib-6.1 builder publishes 11 component rows, 28 keyboard starters, 4 manufacturer-parts shortcuts, 10 recorded 2u assemblies, 68 exact measured-dome mappings, and 241 decision-changing pair edges backed by a complete 3,570-edge compatibility audit closure. The release changes the Parts Builder and its declared supporting files only. The fc-3.5 viewer overlay preserves those builder bytes. Neither update changes the fc-3.4 scientific evidence or perception-index model. The fc-3.5 viewer adds the Simplified/Detailed graph-display contract, unified collapsed filters, fleet-wide profile controls, the Force-wall-onset comparison, fixed-height comparison charts, drafting-style measurement geometry, and PNG screen parity with timestamp and watermark. It keeps the 4.5 mm shared displacement scale and explicitly separates detected force-wall onset from the recorded turnaround test limit. ## Paper and research compendium **Beyond Snap Ratio: Reproducible Force–Travel Measurement and Exploratory Perceptual Correlates of Weight and Collapse Sharpness in Electrocapacitive Domes**, Brian Gebo, Version 2.1, 2026-09-04. - Paper DOI: - All-version concept DOI: - Research-compendium DOI: - Paper PDF SHA-256: `1de8e71e32b557e4cffeffe03ffb13a6326789e99b04890147043f6f7728c862` - Paper manifest SHA-256: `4c9e664529f70ccb35573daab6a0248d8642d04534aef02b6b87aca8359b1686` The paper is a preprint and has not been independently peer reviewed. Its manuscript and original figures are released under CC BY 4.0. Files in the research compendium retain the path-scoped rights stated in that compendium; the paper license does not silently relicense the bench software, repository documentation, raw data, or third-party material. ## Storefront release and rollback boundary The public Shopify navigation exposes Dome Lab and its released pages. The pre-release review page, review article, review theme, and pre-Dome-Lab menu backup were retained in Shopify on publication day. They are rollback assets, not public release authorities, and should remain retained through at least 2026-09-14. Preview keys or private administrative links must never be added to the repository. The separately retained final Shopify release kit has SHA-256: `b7aa49f550c56b29035e24659fb8f3c9588b4d34d85e8059ee1a88869fedcc9a`. It is an operational backup, not part of the public repository package. ## Interpretation boundary The tools provide versioned bench measurements and evidence-scoped compatibility information. They do not establish universal product quality, comfort, preference, manufacturer specifications, or causal perceptual laws. The 25-dome subjective pilot is exploratory. The multi-rater study protocol is frozen as `perception-validation-v1` in [`prospective-study/`](prospective-study/README.md); no confirmatory result exists until that study is conducted and analyzed under the frozen plan.
