Three connected fixes after the user spotted the 2026-05-28 IT log
cutting off mid-sentence:
1. translation: bump max_tokens 4000 → 8000.
call_llm()'s default cap was 4000, which is what the English log
generator itself uses as its ceiling. Italian expands roughly 15-25 %
over English in tokens, so any near-cap English source produced an
IT translation that hit finish_reason=length and returned a
truncated body — silently, because _call_provider() only raises when
content is fully empty. The strategic_log_translations table has
dozens of rows where completion_tokens landed at exactly 4000 with
content well under half the source length. 8000 gives ample
headroom for any of the five LANGUAGES we ship (en/it/es/fr/de).
2. log.html: localise the chat sidebar strings.
user_lang was already passed into the template by pages.py, so an
inline {% if user_lang == 'it' %} keeps it simple. Covers the
"Ask Cassandra" title, the "grounded on…" hint, the helper lede,
the textarea placeholder, and the Send button label.
3. chat endpoint: append respond_in_clause(user.lang) to the system
prompt. The chat conversation can now happen in IT — the model's
first reply lands in the right language even when the user's first
turn is short.
scripts/backfill_truncated_translations.py: one-off cleanup utility.
Scans strategic_log_translations for rows whose translated content is
< 70 % of the English source (the truncation signal — IT *expands*
beyond English, so a shorter translation is always suspect), deletes
them, and re-translates via the now-uncapped service. Supports --date,
--since, --all and --dry-run. The 2026-05-28 fan-out has already been
re-translated (13/13 rows). Other historical dates still hold older
truncations; the user can decide whether to backfill those (the script
is idempotent).

api.py was 933 lines mixing four distinct concerns: indicators +
news + strategic log (the JSON/HTMX API proper), the chat endpoint
+ its three private helpers (~200 lines), and the two HTML-only ops
endpoints /markets-bar + /health (~150 lines).
Extracted:
- app/routers/chat.py — POST /api/chat + _latest_quotes_by_group_chat,
_thesis_headlines_for_chat, _month_spend
- app/routers/ops.py — GET /api/markets-bar + GET /api/health +
_fmt_price helper
Both new routers use the same dependencies=[Depends(require_token)]
as api.py and are mounted at the /api prefix in app/main.py.
URL surface is byte-identical with no externally-visible change.
api.py shrinks to ~620 lines focused on indicators+news+log+settings.
Helpers shared with the original api.py (_md_to_html, _resolve_tone_param)
are imported from app.routers.api where needed in chat.py to avoid
duplication.
Also updated tests/test_chat_and_log_gates.py to mount chat_router
in its local test app, since /api/chat now lives there.
