docs(14.2.1): lock Go tables to golem15_translate_*

Execute-phase Task 2 chose golem15-prefix over the researched winter_translate_* names so the plugin ships vendor tables; PHP winter names stay a later import mapping.

 Phase 14.2.1 ports the lean core of `Golem15.Translate` at SHA `725d547ec839f02b5fdc0f0a6faaed601a414d50` so Journal (Phase 15) can keep translatable fields. The frozen tree is present at `/media/nvme/dev/golem15/fonoteka/plugins/golem15/translate` and matches the pin. Do not clone a second copy.
 
-**Primary recommendation:** Create `sm-translate-plugin` on the user-plugin mount pattern; squash PHP's rainlab→winter rename history into four final Postgres tables named `winter_translate_*` (not `golem15_translate_*`); export `Translatable() []string`, `WithLocale`, get/set-in-locale, and Translator current locale; land cabana `markdown` plus `mltext`/`mlmarkdown` in this phase so Phase 15 is not blocked; replace surf's Accept-Language-only house locale middleware with a backpack-published Translator when the plugin is mounted.

-PHP table names in this pin are `winter_translate_locales`, `winter_translate_attributes`, `winter_translate_indexes`, and `winter_translate_messages`. CONTEXT D-10's `golem15_translate_*` placeholder is wrong against the frozen source. Use the verified `winter_translate_*` names so a Winter import and Journal cutover see the same tables.
+PHP table names in this pin are `winter_translate_locales`, `winter_translate_attributes`, `winter_translate_indexes`, and `winter_translate_messages`. **Execution override (2026-10-06):** D-10 is locked to Go names `golem15_translate_*` with the PHP column/index shapes. Do not emit `winter_translate_*` in Go DDL. A Winter import will need a mapping later.

 ## Common Pitfalls
 
 ### Pitfall 1: Wrong table prefix
-**What goes wrong:** Creating `golem15_translate_locales` because CONTEXT guessed that name.
-**Why:** D-10 asked the researcher to confirm; models say `winter_translate_*`.
-**How to avoid:** Use the verified names in every migration and query.
-**Warning signs:** `Schema::hasTable('winter_translate_locales')` in Translator.
+**What goes wrong:** Creating `winter_translate_locales` in Go because PHP models use that name.

+**How to avoid:** Use `golem15_translate_*` in every Go migration and query.
+**Warning signs:** Go source containing `winter_translate_` or `rainlab_translate_`.
 
 ### Pitfall 2: Nested ML save dropped
 **What goes wrong:** SPA posts `{title: {en, pl}}`; cabana drops maps; only default locale saves.
