prosolis 3cc23b8ea4 The advice arrived in the language she was trying to read her way out of
Reported as "the Portuguese option isn't translating the advice in
English — it's just reprinting Portuguese." Nothing was wrong with
targetFor. It was reading a direction the account could not leave.

learnerPairs held only zh, so SetPair refused learning_pair for pt-PT
and every Portuguese account was learning_en by force. targetFor then
did exactly what it says: explanations follow the half of the pair she
is not learning, which for a forced learning_en account is Portuguese.
A Portuguese document, corrected in Portuguese, explained in
Portuguese, with no way to ask for English — correct behaviour derived
from a fact about the roster that was no longer true.

The note in learnerPairs was written one phase too early to see it. It
said turning a pair around needs a word list and a dictionary reading
into English, and that fr, es and pt-PT had neither. Portuguese has
both. Word boundaries are spaces — the megabyte jieba needs is a
property of a writing system that doesn't use them, not a debt every
pair owes. And the dictionary arrived with dict.db, which reads pt→en
as readily as en→pt; dreamProvider.reverse has been answering that
question since the pair shipped. What was actually blocking the pair a
native English speaker learning Portuguese needs was this list.

So pt-PT joins it, and the pt-PT pack gets the learner copy the control
renders from — each label in the language of whoever would pick it,
since someone on the wrong side of that switch cannot read the side
they are reaching for. fr and es clear the same two bars through the
same dict.db and stay out: their packs carry no learner block yet,
which is a translation question rather than a data one, and the server
should keep saying no until one is written.

Two things that assumed learning_pair meant Chinese, now that it
doesn't. The segmenter gate reads the pair as well as the direction, or
a Portuguese learner would load a megabyte of Chinese word list and
hover Portuguese words at /api/hanzi. And that endpoint's own comment
justified skipping providerFor with a guarantee it no longer has; the
real guarantee was always the caller's — it is only ever asked about
tokens the Chinese segmenter found — and a stray lookup was already
safe, answering a miss with an empty 200.

Tests in both packages. The auth test that pinned pt-PT's refusal now
pins its acceptance, with fr and es still refused; the suggestions test
pins the consequence where it actually lands, which is the language she
reads her advice in.

prosolis 77f284f65c The zh pair's other direction, and a rule pack that mostly says no
`pair_lang` had always been answering a second question nobody asked: it
says which two languages, and every surface built on it assumed English
was the one being learned. That is why hanzi is never tokenized, never
spell-checked, never glossed — correct for a Mandarin native practising
English, backwards for an English native practising Mandarin.
`users.direction` (migration 0016) separates the two questions; a
`zh-learner` pair code would have been cheaper and would have made two
directions of one pair look like two unrelated languages to every query.

Segmentation is what replaces `wordAt` where there are no spaces: a
shortest-path walk over log-probabilities, 232 ms and 14 MB for 188,522
words. The browser gets the word list because segmentation runs on hover;
the server keeps the whole dictionary. Their coverage gates come out
opposite on purpose — the client list is frequency-gated because the
segmentation is measurably identical without the tail, and the dictionary
is gated by nothing, because its only power is to explain and the word a
learner stops on is the rare one.

The 错别字 pack is 24 confusable pairs behind two mechanical gates. One
admits a pair only if the wrong form is not a dictionary word and the
right form is, which is why it refuses 自已 for 自己 — a real error whose
wrong form is a headword. The other asks the segmenter whether the two
characters already belong to two different words, without which 自己经常,
睡觉的时候 and 不知到底 would all be corrupted silently into text still
made of real characters.

Not deployed (this carries a migration), not seen in a browser, and no
account has ever been in the learner direction. The IME composition
guards were in scope and are not done — see BUILD_PLAN Phase 26.

prosolis 9224c44fff 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.

go build/vet/test, tsc, vite, vitest 251/251.

Not deployed, not seen in a browser, not read by a native speaker, and no
es account exists.

prosolis 071ea7b835 Petal learns French, and the pack that shipped was misspelling itself
Phase 24, the fr half: langpack, Hunspell dictionary, Piper voice, and the
lexicon coverage that turned out to have been measured already (63.1%, better
than pt-PT's 62.1%). No migration; not deployed.

The plan recorded that build_ptpt_dictionary.py "generalizes" to French. It
did not. It handled single-character flags and plain PFX/SFX and stopped on
everything else, and fr.aff uses four of the things it stopped on. FLAG long
is the dangerous one: French flags are two characters, so the old reader's
set(flagstr) yields a bag of unrelated letters and expands every entry through
the wrong paradigm without ever erroring. Plus continuation flags (French
really does affix an affixed form), NEEDAFFIX on 68,075 of 84,140 stems, and
FULLSTRIP. Renamed build_hunspell_dictionary.py with a per-language profile,
asserting that CIRCUMFIX and FORBIDDENWORD are still unused rather than
assuming it — and it rebuilds pt-PT byte-identical to the shipped asset, which
is the only thing that makes "generalized" a claim rather than a hope.

Elision was decided by building both halves and measuring. Keeping l'arbre and
its thirty-three siblings: 3,159,832 forms, 8.25 MB gzipped. Dropping them:
473,326 and 1.19 MB. They are not new words, but the tokenizer keeps internal
apostrophes, so they genuinely would have been underlined — so they moved out
of the dictionary into withElision, which splits at a known clitic and still
requires the remainder to be a word (l'zzzz stays flagged). Real nspell: 369 ms
and 74 MB, against pt-PT's 842 ms and 139 MB, on the larger language.

Where the regional trap lives is the mirror image of Portuguese's: every fr_*
Piper voice is fr_FR and Debian's fr_FR/fr_CA/fr_BE dictionaries are one shared
word list, so nothing can be quietly wrong about the country and the whole
decision sits in the copy. What French has instead is the 1990 reform, packaged
three ways; comprehensive ships, because Petal never corrects her French and
coût and cout are both correct.

Then the interim review pass, at the user's suggestion and explicitly "for
now": four models read each Latin pack independently, and only findings at
least two of them reached on their own were applied — five per pack. It earned
its keep on the pack that was already live. pt-PT was carrying pre-Acordo
spellings (adjectivos, actualmente) in a file whose own header commits to
post-Acordo, plus Brazilian decepção, because the Phase 21 greps checked for
Brazilian vocabulary and never checked the pack against its own spelling
policy. That grep now exists and was confirmed to fail on the old text before
being kept. Where reviewers agreed a line was wrong but split on the fix, the
wording is mine and the reasoning is in BUILD_PLAN rather than averaged away.

Still owed, and both packs now say so precisely: a quorum of models agreeing is
agreement, not authority. No native speaker has read either pack, and none of
this has been seen in a browser.

go build/vet/test clean, tsc, vite build, vitest 190/190.

prosolis 1f4ca4775a Let her choose her own pair
Raised by the user, not by the plan: there was no way to change language
in the mobile UI. There was no way anywhere. `users.pair_lang` has been
readable since Phase 19 and writable by nobody — /api/me was GET-only and
Upsert deliberately skips the column — which is also why "no pt-PT account
exists yet" has stood through two phases. Nothing could create one.

PATCH /api/me answers with the whole user rather than 204, so the client
re-reads the pair from the server instead of trusting its own request. One
write reaches everything: langpack, Hunspell dictionary, Piper voice,
lexicon provider and prompt language all read the column at use time.

The server refuses a pair it has no copy for, and auth.shippedPairs is
deliberately not internal/llm's list. That one names pairs the prompts can
talk about (fr and es, since Phase 19); this one names pairs Petal can
render itself in, which needs a langpack. Storing fr today would strand
her on Chinese with no way back except a lucky guess at a button she
cannot read.

The picker sits in the sidebar footer because the sidebar is the mobile
drawer — always one tap away. The status bar exists only while a document
is open, which is the wrong moment to find the app speaking a language you
can't read. Each language names itself, 中文 and Português: the one place
bilingual copy would get in the way.
