v0.248.0: i18n slice 1 release A — apps and settings in English, Hungarian byte-identical (R-556)

Ten pages converted against fixtures captured from unconverted templates (6be55a0); marker
coverage test; English page mask narrowed; English retrieval-promise stems; common keys;
title keys and infraMeta from the bundle; old wording tests read the Hungarian expansion.

+## v0.248.0 — English for apps and settings: ten more pages, Hungarian byte-identical (2026-09-17, R-556 release A)
+
+**MinAgent: 0.131.0** (unchanged). **No hub release needed.** Nothing changes for a Hungarian household:
+the switch is still shown only on English pages (decision 6 stands until release C).
+
+- **Converted:** `dashboard`, `stacks`, `logs`, `monitoring`, `app_import`, `app_export`, `deploy`,
+  `settings_system`, `settings_security`, `settings_notifications` (572 markers). `app_row`,
+  `meta_badge`, `icons` carry no copy (verified). 16 repeated strings now share `common.*` keys
+  where the meaning is the same everywhere; „Mentés" (Save/Backup), „Frissítés" (Update/Refresh),
+  „Indítás" (Start/Boot) deliberately stay per page.
+- **Parity:** 25 new fixture states captured from the UNCONVERTED templates (commit `6be55a0`) before
+  any of these pages carried a marker. Five v0.247.0 fixtures were re-captured from v0.246.0
+  (`89dd3e94`) because their one-word Hungarian data had to become multi-word (below).
+- **New test — `TestI18nParityCoversEveryMarker`:** every marker occurrence must be rendered by some
+  parity case. It found two gaps in v0.247.0's own pages (the app page's Install button; one „Due"
+  tag), closed with two new cases captured from v0.246.0.
+- **English page test widened:** only fixture strings of 2+ words or 12+ characters are masked; titles
+  go through `addLanguageData`. Measured: with one English nav key deleted, the old test flagged 8
+  cases and missed the 6 launcher cases; the new one flags all 14.
+- **Retrieval-promise gate reads English** (`EN_PATTERNS`, `ALLOWLIST_EN`): HEAD passed a planted
+  „Your old backups can be restored at any time." in `en.json`; the gate now convicts it and accepts the
+  same place carrying a sentence that promises nothing. Decoys in `test_gate_decoys.py`.
+- **Go-side copy on these pages:** titles via `TitleKey` (dashboard, stacks, monitoring, the three
+  settings pages); `infraMeta` descriptions (and samba's name) from the bundle, Hungarian pinned equal
+  to `inframeta.go`.
+- **Found, not converted:** `backups_remote.html` decides with `indexOf('Fut')` against its own
+  Hungarian status text (row filed); converting that word would silently break the English page's
+  progress poll. Composite page titles (logs, deploy, export) and `lifecycleBadge`/`updateBadge`
+  remain Hungarian — slice 2.
+- **Extractor:** ASCII-only Hungarian it missed on these pages — Mind, Folyamat, Titkos, Processzor,
+  Hamarosan, aldomain, „Az adatai itt voltak", Figyelem, pelda@email.hu — converted by hand; words added
+  to its list (not „Mind": an English homograph). It also learnt that a JS string can start inside an
+  attribute value.
+- `HU_FORMAL_CEILING` 6 → 10: the converted copy carries four more „ön" forms (R-516), unchanged by rule.
+- Old wording tests (`TestDiskMeter_*`, `TestNetworkBadgeTemplates_DistinctStrings`,
+  `TestSettingsSectionInventory`) read the Hungarian expansion (`huTemplateSource`), not the raw file.
+- `loadTemplates` logs its parse duration per language (DEBUG).
+
+**Red-proofs** (`felhom.eu/documentation/audits/i18n-slice1-2026-09-17/A/redproofs.txt`): parity (one byte
+of `dashboard.lemezek_allapota` → 4 dashboard cases name line and bytes); coverage (a marker in an
+unreachable launcher branch → named, while parity stayed green); mask widening (8 vs 14 cases);
+retrieval gate (HEAD rc 0 on the planted promise → fixed gate convicts, negative control accepted).

 ## v0.247.0 — the dashboard can speak English: mechanism proven on three pages, Hungarian byte-identical (2026-09-17, i18n spike)
