feat(native): search follow-up questions with the previous question - #80
Conversation
Retrieval searched only the question's own words, so a follow-up ("What did he publish?", "What
are the side effects?") found no sources and was answered from the model's memory, uncited.
FollowUp ports src/routing/followUp.ts from rferrari#72 (brought here with its vitest tests): a question that
points back (he, it, isso...) is searched with the previous question, then the previous question
alone; a short question with no name of its own falls back to it when it finds nothing; one that
names its own subject never borrows. Used by the default path (AnswerPipeline) and adaptive routing
(PlanExecutor), which compress against the words that found the sources. The recorded executor
golden has no history, so it's unchanged. Golden test: scripts/export-native-golden-followup.mjs
(55 questions from the eval sets, the conversation runs and edge cases; 330 plans, 804 searches).

Distinguish existential and locative uses of there.
POINTS_BACK matches bare there, so “Is there an effective treatment?” enters the back-reference path. If the combined search returns no chunks, FollowUp.search then searches the unrelated previous question.
Do not replace there with only there\?. That change would preserve “There?” and “What happened there?”, but it would stop matching the valid locative reference “Were they there last week?”. Add an existential-context distinction to the matcher. Keep the locative cases as back-references, and leave namesItsOwnSubject unchanged. Mirror the distinction in src/routing/followUp.ts and add the cases to the generated parity fixture.

Recognize a named subject in the first word.
namesItsOwnSubject skips the first word. For a query such as "EIP-1559?", the initial search can return no chunks, then FollowUp.search searches an unrelated previous question with the query. Treat an initial named subject as its own topic, and update the TypeScript rule and golden fixture to keep parity.

Do not treat existential there as a back-reference.
This affects the TypeScript test and golden-generation path, not a production TypeScript retrieval caller. In followUpSearch, there can still select the direct plan for “Is there an effective treatment for malaria in adults?”. If that combined search returns no chunks, searchWithFollowUp can retry with an unrelated previous question. Distinguish existential there from a location reference before selecting the direct plan.

Skip only the current turn, not every matching question.
If a user repeats “What are the side effects?” after another topic, this loop skips the immediately preceding question because its text matches query. It can then select the older topic as the fallback. Identify the current turn by its position when history includes it; allow an earlier turn with the same text to remain the previous question.

Check the first word for a subject name.
For “Australia capital?”, .slice(1) discards Australia. The short-query branch then permits a fallback to an unrelated previous question when the initial search misses. Exclude an initial question word without discarding an initial subject name.

…up rule From CodeRabbit's review of rferrari#80, in the TS rule, the Kotlin port and the golden file: - "there" points back only as a place ("What happened there?", "Were they there?"), not in an existential "is there"/"there are": "Is there an effective treatment for malaria in adults?" could otherwise retry with the unrelated previous question when its combined search found nothing; - a name as the first word counts as the question's own subject ("Australia capital?", "EIP-1559?"), unless it is a word questions open with (question words, auxiliaries, request verbs, English and Portuguese).

Retrieval searched only the question's own words (
AnswerPipeline.kt:72,PlanExecutor.kt:137). A follow-up like "What did he publish?" or "What are the side effects?" found no sources, and the model answered from memory, uncited. For the bounty's quality bar that's the weaker case: Qwen3-4B scores 0.49 from memory vs 0.61 with good passages. In the Expo app with #72, both questions in our conversation test got sources.FollowUp(engine,answer/) portssrc/routing/followUp.tsfrom #72. Using the conversation's previous question:It's wired into both paths: the default

Each question is tried with 6 kinds of history (none, empty, a previous question, a history already holding the current question, assistant-only, blank turns): 330 plans (48 point back, 54 fall back, 228 search as written).
