Context

FR-3052 (PR #7748) introduced CHECK 3 in scripts/check-terminology-i18n.mjs — a detector for capitalized user-facing nouns in i18n values that are not yet in the terminology.json termbase (candidate new terms). It is intentionally OFF by default (opt-in via --check3), report-only, and non-blocking.

Running it today surfaces 25 candidates in resources/i18n/en.json. This issue triages them: register the genuine domain terms into terminology.json, silence the noise via the ignoreNouns allowlist (or fix the string), and — once the report is near-zero — evaluate promoting CHECK 3 from opt-in to a default warn.

Reproduce: node scripts/check-terminology-i18n.mjs --check3 --json (or --warn --check3 for the text report).

Classification

🟢 REAL — register as terminology.json concepts (with decidingFR)

🟡 BORDERLINE — editorial decision (register OR allowlist), owner = docs-lead

🔴 NOISE — allowlist (scripts/terminology-i18n.allowlist.json ignoreNouns) or fix the string

• Clipped fragments: Numeric User (Numeric User ID clipped before the ID acronym), Pre-defined Prometheus (third-party Prometheus; add to ignoreNouns), Preopen Ports' (stray trailing apostrophe from the source string).
• Sing/plural dupes: Selected Image / Selected Images.
• Theme/logo fragments: Dark Mode WebUI, Light Mode WebUI.
• Page-name fragments: Admin Data Page, Project Admin Data (both from the same Admin Data page alerts).
• Generic UI microcopy / sentence fragments: App Name, Current Project, Connection Example, Hostname Already Exists, Log Messages, My Account, Notebook Address.

Tasks

1. Register the 🟢 REAL candidates as concepts[] entries in terminology.json (per-language preferred where known, decidingFR = this issue), regenerate TERMINOLOGY.md (pnpm run build:terminology), and re-run check:terminology-md.
2. Make the 🟡 BORDERLINE calls via the docs-lead New-Term Gate; fix the Preopen Ports' apostrophe capture (string or detector).
3. Add the 🔴 NOISE items to ignoreNouns (or fix the underlying string, e.g. the Numeric User ID clip and the Selected Image(s) dupes). Document each addition in the allowlist $comment.
4. Re-run node scripts/check-terminology-i18n.mjs --check3 and confirm the report is near-zero (target < ~5 residual).
5. Then evaluate promoting CHECK 3 from opt-in → default --warn in scripts/verify.sh / lint:terminology (still report-only; a later, separate decision could make it blocking). Team sign-off required for any default-on flip, same as FR-3049.

Acceptance criteria

• 🟢 candidates registered in terminology.json with decidingFR; TERMINOLOGY.md regenerated; generate-terminology.mjs --check green.
• 🟡 candidates each resolved (registered or allowlisted) with a one-line rationale.
• 🔴 candidates allowlisted or their strings fixed; allowlist $comment updated.
• --check3 residual count driven to near-zero and recorded in the PR.
• A documented recommendation on whether to promote CHECK 3 to default-on (with the residual count as evidence).

Dependencies

Builds on FR-3052 (PR #7748) — the CHECK 3 detector + ignoreNouns allowlist must be merged first. Relates to the terminology governance roadmap (FR-3048 / FR-3049 / FR-3050 / FR-3051).
