Index cached reviews for place search and chat - #147
Port cached review indexing from demflyers-favorites #171 into the public pipeline and search runtime without private site data or configuration.
Index up to 12 topic labels and five 180-character snippets, deduplicated and excluding reviewer identities/profiles.
Search review-only dishes and atmosphere with lower lexical weight than curated text, including Unicode/CJK phrase matching.
Send at most two query-relevant fragments per shortlisted place to the existing chat prototype. Model rejection remains an empty result; the shared selector accepts retrieval alternatives for structured-intent consumers.
Verification
153 frontend tests pass, including review-only retrieval beyond the candidate cap, negative-review rejection, snippet limits, alternative selection, curated priority and CJK queries.
Two focused Python tests pass for cache-to-normalization-to-search propagation and metadata exclusion.
Rebuilt example data; bun run check passes with zero Astro errors/warnings and clean Biome checks.
Chat-enabled bun run build passes.
No generated assets, cache mutations, site configuration, or credentials included.
Limits
Indexes cached samples only, with lexical retrieval rather than embeddings. Review mentions are anecdotal and can be negative or outdated; the model receives context to evaluate them.
Note
Medium Risk
Changes shared search ranking and chat model inputs using untrusted review text; identity gating and prompt framing reduce wrong-place and over-trust risk, but lexical matches can still surface negative or stale mentions in results.
Overview
Adds bounded review_evidence (up to 12 topic labels plus five 180-character snippets, deduplicated, no reviewer metadata) from the enrichment cache into normalized places and the search index, only when cached place identity matches the saved list entry—same guard as recommendation copy.
Search joins that text at index prep time with lower scoring than curated notes/tags; review text can satisfy vibe constraints (e.g. “calm” via “quiet” in a review) and token/phrase matching now supports Unicode/CJK. Guide card data-search includes review evidence for on-page filtering.
Place chat attaches at most two query-relevant review fragments per shortlisted candidate (using the last two user turns, shared createReviewEvidenceScorer with search), and the system prompt treats reviews as untrusted anecdotal data so negative mentions do not auto-recommend.

Summary by CodeRabbit
New Features
Place search can now match relevant phrases found in review evidence, including Chinese, Japanese, and Korean text.
Place chat can use query-relevant review snippets to inform recommendations, including negative feedback. Reviews are presented as anecdotal evidence, not confirmation of a feature.
Review evidence is limited and excludes reviewer details.
Documentation
Added guidance on how review evidence is used in search and chat.
Review feedback addressed
Model rejection does not force review-only recommendations.
Evidence selection shares search normalization and atmosphere aliases; structured intent alternatives are retained where supported.
Public chat keeps preceding user context for city-only clarifications.
Single-character CJK queries and accented review text retain evidence.
Cached review evidence must pass the existing saved-place identity guard.
Regression tests, static checks and chat-enabled builds pass locally.

Walkthrough
The search index now carries bounded review evidence. Place search can match that evidence, including CJK phrases. Chat prompts include query-matched review snippets for candidates, with instructions that treat reviews as anecdotal evidence.

Summary
Review evidence data and index scripts/pipeline_models.py, src/lib/types.ts, scripts/build_data.py, tests/python/test_build_data.py, docs/ARCHITECTURE.md
Normalized places and search-index entries include review evidence. Evidence is deduplicated, bounded by item counts and character limits, and excludes reviewer metadata. The architecture documentation describes its indexing and use.
Review evidence place search src/components/PlaceCard.astro, public/scripts/place-search.js, tests/frontend/placeSearch.test.mjs
Place search includes review evidence in its search text and tokens. Review matches can satisfy vibe constraints with a lower score than tag matches. Unicode normalization and CJK phrase matching are supported.
The chat API selects up to two query-matched review snippets for each candidate. The system instructions treat reviews as potentially anecdotal, outdated, or negative. Tests cover snippet selection and empty model-selected place lists.

Merge Risk: Low · previous review c946d
Some matching reviews may be absent from chat responses for accented queries, single-character CJK queries, or conversational follow-ups. These bounded gaps warrant a fix or owner acceptance but do not block search retrieval.

Review comments at @functions/api/chat.js:
- Line 129: Update modelMessages so review_evidence selection uses the latest
user message plus the preceding user message as alternative context; keep the
latest message as the primary query and pass the prior context to
relevantReviewEvidence for each candidate.
Review comments at @functions/lib/chat-review-evidence.js:
- Around line 7-8: Update the term filter so single-character CJK search terms
are retained while the length-greater-than-one rule remains for other scripts;
preserve the existing stopword exclusions.
- Around line 3-5: Update the normalize helper used to build terms in review
matching so query terms and review snippets use the same Latin accent folding as
normalizeText in place-search.js, allowing unaccented queries to match accented
review text.
