Problem

The reported chat failed on basic vocabulary and follow-up corrections even though the governed dictionaries already contained the needed entries. English sentence translation did not retrieve component concepts, spaced phone/OCR input missed exact headwords, correction follow-ups lost the original sentence, and the UI implied that any attached source verified the whole answer.

Changes

  • retrieve exact governed dictionary anchors for English sentence concepts, including conservative English inflection handling
  • match spaced or punctuation-light learner input such as ma a nao as a candidate without presenting it as an exact transcription
  • filter proper-name dictionary entries from ordinary passage matching
  • recover the original user-authored sentence for corrected-sentence follow-ups
  • recognize natural image requests such as What does all of this say?
  • preserve the separate RAG token allocation instead of truncating retrieved evidence under the base system-prompt budget
  • carry answer, partial, and candidate support scope through the API
  • label the UI as Sources, Partial evidence, or Possible match based on actual support
  • suppress meaningless page 0 locators

No existing knowledge source or resource was removed or changed.

Verification

  • ./scripts/check.sh
    • API: 498 passed, 4 skipped
    • source governance: 32 registered and 32 reviewed
    • source-routing benchmark: 33/33
    • web: 306 passed
    • lint: 0 errors (7 existing warnings)
    • typecheck, production build, PWA checks, and bundle budget passed
  • local browser QA through the signed-in app verified:
    • the original reminder/class sentence uses maleffa and explains component-level support
    • ma a nao resolves to a possible dictionary spelling match for afraid/scared
    • maleffa returns a source-supported definition for forget
    • corrected-sentence follow-up recovers and fixes the original sentence
    • banana returns aga as the ripe-banana dictionary entry
    • blue returns Asut with cited variants
  • Fixes source-aware translation retrieval with conservative inflection, spacing, punctuation, and diacritic handling.
  • Excludes proper-name entries from passage matching and recovers original sentences for corrected-sentence follow-ups.
  • Recognizes broader image-content translation requests and expands Chamorro passage guidance.
  • Preserves separate RAG token allocation for streaming and non-streaming responses.
  • Adds support_scope (answer, partial, or candidate) to API and web source citations.
  • Updates evidence labels to distinguish Sources, Partial evidence, and Possible match.
  • Suppresses non-positive page locators in citations.
  • Changes the SourceInfo schema and getChatEvidenceStatus signature. API and web clients must support the new metadata and argument.
  • No knowledge sources or resources changed. No migration is reported.
  • Reported validation passed for API, web, governance, routing benchmark, lint, typecheck, production build, PWA, bundle, and browser QA.

📝 Walkthrough

Walkthrough

The PR expands translation classification and contextual retrieval, adds normalized dictionary concept matching with scoped citations, reserves RAG prompt budget, and updates web evidence labels and page rendering.

Changes

Translation and retrieval flow

Layer / File(s) Summary
Translation request classification
api/src/rag/conversation_retrieval.py, api/src/rag/image_translation_context.py, api/src/rag/translation_policy.py, api/tests/test_conversation_retrieval.py, api/tests/test_image_translation_context.py, api/tests/test_rag_query_contract.py
Corrected-sentence, deictic, whole-image, and passage translation requests now produce contextual queries and Chamorro passage guidance.
Dictionary concept and citation evidence
api/api/canonical_context.py, api/tests/test_canonical_context.py
Canonical context now retrieves normalized learner candidates and English passage concepts, filters proper-name entries, and emits merged registered citations with support metadata.
Backend citation and prompt wiring
api/api/models.py, api/api/source_citations.py, api/api/chatbot_service.py, api/tests/test_source_citations.py, api/tests/test_system.py
Source records preserve support_scope. Streaming and non-streaming prompts use contextual queries and reserve space for retrieved context.
Frontend evidence status and citation rendering
web/src/lib/chatEvidence.ts, web/src/types/source.ts, web/src/components/Message.tsx, web/src/components/SharedConversation.tsx, web/src/components/SourceCitation.tsx, web/src/components/Chat.tsx, web/src/lib/chatEvidence.test.ts, web/src/components/Message.evidence.test.tsx
The interface distinguishes answer, partial, and candidate support. Citation displays omit non-positive page numbers.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to d0ebf

Translation requests using deictic wording and optional destination language preserve their passage content for retrieval and translation. No current merge-blocking risk remains.

Inline comments:
In `@api/api/canonical_context.py`:
- Around line 898-901: Update the candidate construction loop over
passage_dictionary_matches to use each match’s near_match value for
support_scope instead of always emitting "partial", so OCR/spelling-near
evidence is labeled as a possible match. Add a regression assertion covering the
existing trabina-style near-match case.
- Around line 409-417: Filter ranked_matches to exclude entries classified by
_is_proper_name_definition before calculating best_rank or selecting a match,
while preserving the existing ranking behavior for remaining entries. Add a
regression test covering an English-to-Chamorro passage with a name-related
gloss and verify that no proper-name headword becomes the preferred lexical
anchor.

In `@api/src/rag/translation_policy.py`:
- Around line 88-93: Update _DEICTIC_TRANSLATION_CUE_PATTERN to recognize
“translate this” and “translate all of this” cues, including optional “all of,”
so cue_match captures the passage in a single paragraph such as “Can you
translate all of this? Buenas ...” rather than extracting only the cue phrase;
add a test covering this one-paragraph input.

In `@api/src/rag/translation_policy.py`:
- Line 93: Update the translation-request extraction logic around the cue regex
so “translate all of this” handles optional destination and polite suffixes
before the question mark, including requests followed by a supplied passage.
Ensure empty deictic requests return an empty payload instead of generic-parser
text, preserve extraction of the subsequent passage, and add regressions in the
existing RAG query contract tests for each listed form.
