Three fixes to the precedent library after the first end-to-end test on
403-17 surfaced runtime issues:
1. Anthropic SDK fallback in claude_session. The legal-ai Docker container
does not ship the `claude` CLI, so every halacha and metadata extraction
was failing with "Claude CLI not found." Module now tries the CLI first
(zero-cost local path) and falls back to the Anthropic SDK with
ANTHROPIC_API_KEY when the binary is absent. Default model is
claude-sonnet-4-6, overridable via CLAUDE_SDK_MODEL env. The system
message gets cache_control: ephemeral so multi-chunk runs reuse the
cached instruction prefix at ~10% read cost. Adds `anthropic` to
pyproject deps.
2. precedent_metadata_extractor crashed with KeyError because the JSON
example inside the prompt template contained literal { } characters
that str.format() interpreted as placeholders. Switched to f-string
concatenation; the prompt template no longer needs format() at all.
3. Library list query stays stale after upload because the upload
mutation's onSuccess fires when the POST returns task_id, not when
SSE reports completion. Added a second invalidate inside the SSE
watcher in PrecedentUploadSheet so the new row appears with up-to-date
chunk and halachot counts the moment processing finishes.
Halacha and metadata extractors now route the long static prompt through
the new `system=` parameter so the SDK path actually caches it; the CLI
path concatenates and behaves as before.

Adds a third corpus of legal authority distinct from style_corpus
(Daphna's prior decisions for voice) and case_precedents (chair-attached
quotes per case). The new corpus holds chair-uploaded court rulings and
other appeals committee decisions, with binding rules (הלכות) extracted
automatically and queued for chair approval.
Pipeline (web/app.py + services/precedent_library.py):
file → extract → chunk → Voyage embed → halacha_extractor → store +
publish progress over the existing Redis SSE channel.
Schema V7 (services/db.py): extends case_law with source_kind +
extraction status fields under a CHECK constraint pinning practice_area
to the three appeals committee domains (rishuy_uvniya, betterment_levy,
compensation_197). New precedent_chunks (vector(1024)) and halachot
tables (vector(1024) over rule_statement, IVFFlat indexes, gin on
practice_areas/subject_tags). Halachot start as pending_review; only
approved/published rows are visible to search_precedent_library.
Agents: legal-writer, legal-researcher, legal-analyst, legal-ceo,
legal-qa get search_precedent_library. legal-writer prompt explains
the three-corpus distinction and CREAC use; legal-qa now verifies that
every cited halacha resolves to an approved row in the corpus.
UI: /precedents page with four tabs — library / semantic search /
pending review (J/K nav, A/R/E shortcuts, badge count) / stats.
Reuses the existing upload-sheet progress + SSE pattern.
