The es pair, and a dictionary that was quietly Spain's

Phase 25. Spanish was never built — the groundwork was all [x] (DreamDict
data, the prompt language, the L1 rule gating, TTS env-discovery), which is
why the plan read as though it had shipped. shippedPairs was the honest
answer: the server had been refusing es on purpose.

The langpack is neutral Latin American, chosen with the user: tú, ustedes,
no vosotros, and the pan-American half of every vocabulary split. A vitest
greps for the peninsular twins the way fr is greped for québécismes —
including coger, which is not merely regional but obscene through most of
Latin America.

The dictionary is the story. Debian's hunspell-es symlinks twenty country
codes to one file, which reads as pan-Hispanic; RLA publishes twenty-four
builds per release, one per country plus a generic es that is the union,
and Debian ships peninsular es_ES. The 58,622-form gap is essentially
voseo, so the first version of this commit underlined vení and tenés as
misspellings and called it a considered gap.

The MUST_ACCEPT list was written to catch exactly that and structurally
could not: it asserted the pan-Hispanic vocabulary, and every RLA variant
carries the full pan-Hispanic vocabulary — only the paradigms are
localised. The REP table cited as the second witness is shared by all
builds too. Two independent-looking proofs, neither able to distinguish
anything, agreeing with each other.

The profile now demands what discriminates, each verified against the build
it targets: voseo rejects es_ES and Debian, vosotros rejects es_MX, and
arepa/chévere/bacán reject es_AR, which has both paradigms and would
otherwise pass. 717,640 forms, 1.74 MB gzipped, 762 ms / 97 MB in a real
nspell. fr and pt-PT rebuild byte-identical from their own upstream debs,
so the shared script still means what it meant.

Shipping the union is fr's call arrived at from the other side: coût and
cout are both correct French, tienes and tenés are both correct Spanish.
The dictionary holds every variety because underlining is all it can do;
the copy picks a register because speaking requires one.

Reviewed by four models at the usual >=2-of-4 threshold, 5 of 27 findings
applied — one catching the bedtime proverb as fr's Qui dort dîne calqued
into Spanish, gloss and all, which is the rule the fr header states. One
below-threshold finding (a missing ¡, seen by 1 of 4 because an absent
opening mark has no closing ! to look wrong against) was applied and turned
into an assertion instead: the suite now rejects any native line that
closes ? or ! without opening one.

piper-es on es_MX-ald-medium, not the es_ES-davefx-medium the plan named —
six of Piper's nine Spanish voices are peninsular, so the obvious pick was
the pt-PT trap through a different door.
