Sprint 16 (commit 25e29c7) is a 2-line fix that switches
OLLAMA_MODEL from kimi-k2.6:cloud to gpt-oss:20b and bumps
max_tokens from 800 to 4000. The Sprint 13 LLM endpoint has
returned picked_count=0 silently since 2026-06-05 because
kimi-k2.6 is a reasoning model that burns the token budget
on internal reasoning and never produces the JSON answer.
The library fill (Sprint 6+) silently took over. Discovered
while answering the user's "is there anything else to refine?"
question.
Live verification: 5/5 test weeks return picked_count 15-21
(was 0/5 before). 11/11 vitest cases pass (4 new from S16 +
7 from S14). npm run build green. No new runtime deps. No
schema change. No UI change.
This commit updates the 6 running docs that track sprints:
- .agent/plan.md — Sprint 16 section (S16.1-S16.4 + Done
when + Out of scope) added after the Sprint 15 sections.
Documents the diagnosis (kimi-k2.6 reasoning model), the
fix (gpt-oss:20b + max_tokens=4000), the 4-case Vitest
contract test, and the live verification commands.
- .agent/context.md — Sprint 16 decisions (D1-D5), open Q1,
and file:line references added.
- Review/sprint16-verification.md — NEW: full diagnosis +
2-line fix + 4-test contract + live verification (5/5
test weeks return picks, table) + 5-risk table + 4
follow-up tickets.
- Review/ui-nielsen-audit.md — Sprint 16 status block added
after the Sprint 15 Round 3 block.
- fix-ui-audit.md — Sprint 16 section (T9.1-T9.5) added
after the Sprint 15 section. T9.1 documents the 2-line
fix in detail (config.py + llm_plan.py + .env). T9.5
surfaces 3 follow-up tickets.
- Review/handoff-ui-audit.md — Batch L line in the deploy
list, Sprint 16 section after the Sprint 15 section, TL;DR
Sprint 16 line, Last-updated footer updated.
- docs/HANDOFF.md — Sprint 16 section after Sprint 15, Last-
updated footer updated. Notes the corrected model choice
and the 4 follow-up tickets.
All 6 docs now reflect Sprint 16. The Sprint 13 LLM endpoint
now works as designed. Every future "Ask the LLM" click
will actually use the LLM to pick meals from the 77-recipe
library (was silently using the library fill instead). The
_ask_llm helper is still the single F9-full seam.
