Next: Alan's review and the fixes

Answers to the four questions asked again on the review page (live since 2026-10-20) and to the refused FrF2 defaults (after the revision of the FrF2 findings) Owner: Alan. Open 1 day. Source: GitHub. 63 answers received (64 filed).
Check in the Upstash console that the counter keys have a time limit Owner: Fadel. Open 2 days. Source: 2026-10-17-alpha-execution-ledger.md.

Then: Milestone 4: Evaluation and documentation

Review of the gold labels (Section 12.1). Owner: Alan. No date. Source: 2026-10-14-ff-design-translator-design.md. Needed by: Milestone 4.
The rule for the production default, with X, Y and Z (Section 12.4). Owner: Fadel, Alan. No date. Source: 2026-10-14-ff-design-translator-design.md. Needed by: Before the test-set run (Milestone 4).
A save of the R library that fails after IndexedDB opens (for example a full quota) leaves the engine start without an answer from WebR 0.6.0. The user sees "loading has stopped" and Retry. Owner: Fadel. No date. Source: 2026-10-14-ff-design-translator-design.md. Needed by: Cross-browser tests (Milestone 4).
Jev's outcome criteria misjudge some design requests, for example requests with level ranges (Section 3.3). Review the wording before Jev's outcome counts again. Owner: Fadel, Alan. No date. Source: 2026-10-14-ff-design-translator-design.md. Needed by: Milestone 4.
Measure the video title cards again with the accent rule (Section 10.3). Owner: Fadel. No date. Source: 2026-10-14-ff-design-translator-design.md. Needed by: Video release (Milestone 4).
The field of application. Alan R. Vazquez proposes to tailor EXPERTA to one field (for example biotechnology, the food industry or manufacturing), because the readers of JQT and Quality Engineering already know FrF2 (his comment of 2026-10-19, decision F13). He will search for papers on applications to choose the field. His answers stay out of the public repository (Section 14.4). Owner: Fadel, Alan. No date. Source: 2026-10-14-ff-design-translator-design.md. Needed by: Before the Milestone 4 test set and the paper draft.

Before the public release

Review of the guarantee table (Section 7.7). Done on 2026-10-19 for 12 of the 13 regions, the class sentences and the additions (center points, replications, resolution only). Asked again (Section 14.4): the claim for 128 runs with 25 to 39 factors, and the claims for the other catalogue entries. The refused defaults 26-17.1 and 27-18.1 stay refused until Alan R. Vazquez revises the FrF2 findings.Owner: Alan. Needed by: Public release. The claims of Section 7.7 apply now: in the 12 regions that Alan R. Vazquez confirmed, for 40 to 64 factors in 128 runs (his answer #61), and for 25 to 39 factors in 128 runs by decision F2 (Xu, 2009, and the check at generation time) until he answers.
Review of the glossary (Section 9.5). Done on 2026-10-19 for 33 of the 35 entries drafted in Milestone 3B. The entries all_2fis_clear and guarantee have new texts, show "Draft, not yet reviewed" and are asked again (Section 14.4).Owner: Alan. Needed by: Public release (release gate, decision P3).
