d845e44ff8 feat(ai): default Anthropic installs to pgvector RAG (4/5) (#1986)
* feat(ai): add Anthropic provider with chat parity (1/5)

Introduces Provider::Anthropic alongside Provider::Openai, implementing
the LlmConcept chat_response contract over the official anthropic Ruby
SDK. Batch ops, PDF, and RAG land in follow-up PRs.

- Provider::Anthropic uses Messages API for sync and streaming responses
- ChatConfig builds requests with ephemeral prompt-cache markers on the
  system prompt and the last tool definition
- MessageFormatter reconstructs multi-turn history (text + tool_use +
  tool_result blocks) from raw Message records, including the paired
  user-role tool_result turn Anthropic requires after every tool_use
- ChatParser maps Anthropic Message into the shared ChatResponse Data
- Registry, Setting, User, Chat default model wired for ANTHROPIC_*
  envs and Setting.anthropic_*; LLM_PROVIDER selects between providers
- Responder forwards raw conversation_history (Array<Message>) so
  providers without hosted conversation state can rebuild context
- OpenAI provider accepts and ignores the new kwarg (no behavior change)

Tests cover provider init, model gating, MessageFormatter for all turn
shapes, ChatConfig request building (max_tokens, system cache, tool
conversion), ChatParser for text / tool_use / mixed blocks, Registry
discovery, and mocked chat_response success / error / function_request
paths. Live VCR cassettes recorded in a follow-up with a real key.

Stacked PRs: 2/5 batch ops + cost ledger, 3/5 PDF, 4/5 pgvector RAG,
5/5 settings UI + disclosure.

* fix(ai): address PR review on Anthropic provider foundation

Surface fixes raised by Codex + CodeRabbit on PR 1/5:

- Provider::Anthropic#chat_response now accepts (and ignores) a
  `messages:` kwarg. Assistant::Responder passes both `messages:`
  (OpenAI-shape) and `conversation_history:` (raw Message records) for
  cross-provider parity, so the previous signature raised
  ArgumentError on the first chat turn through the Anthropic provider.
- Provider::Anthropic#supports_model? bypasses the `claude` prefix
  gate when a custom base_url is configured, mirroring the OpenAI
  provider. Bedrock-shaped IDs like
  `anthropic.claude-sonnet-4-5-20250929-v1:0` and
  `claude-opus-4@20250514` are otherwise rejected by
  Assistant::Provided#get_model_provider and the chat dies.
- Setting.anthropic_access_token is now in
  EncryptedSettingFields::ENCRYPTED_FIELDS so the Anthropic API key
  is encrypted at rest like every other provider secret. Previously
  plaintext while siblings (openai_access_token, twelve_data_api_key,
  external_assistant_token) were ciphertext.
- Chat.default_model falls back to whichever provider is actually
  configured. Previously, with LLM_PROVIDER=anthropic but no
  Anthropic credentials, the default model resolved to a Claude ID
  that no registered provider supported, so chats failed even when
  OpenAI was fully configured. Adds Provider::{Anthropic,Openai}#configured?
  class methods for the readable callsite.
- Provider::Anthropic.effective_model uses
  `ENV["ANTHROPIC_MODEL"].presence || Setting.anthropic_model` so the
  Setting lookup is only performed when the env var is absent — the
  previous `ENV.fetch(KEY, default)` evaluated the default arg
  eagerly on every call.
- Provider::Anthropic::ChatConfig#anthropic_input_schema strips both
  `:strict` and `"strict"` keys so JSON-decoded schemas with string
  keys cannot leak the OpenAI-only flag through to Anthropic.

Test coverage added: supports_model? bypass on custom endpoints,
chat_response messages: kwarg compatibility, default_model fallback
in the three credential combinations, configured? against ENV +
Setting, strict-flag stripping for both key types, and a
`Setting.expects(:anthropic_model).never` assertion proving the
ENV-precedence test now exercises the lazy path.

All 4365 tests pass (1 pre-existing libvips env error unrelated).

* test(chat): make default_model tests resilient to ENV model overrides

CodeRabbit flagged on PR review: the new default_model tests asserted
against Provider::*::DEFAULT_MODEL, but Chat.default_model actually
returns Provider::*.effective_model.presence (which reads
OPENAI_MODEL / ANTHROPIC_MODEL from the environment). With either env
var set, the tests would fail intermittently even though routing was
correct.

- New default_model tests now assert against the provider's
  effective_model directly, so they verify the routing decision
  (which provider's value wins) without coupling to the constant.
- Pre-existing "creates with default model" assertions had the same
  brittleness; switch them to compare against Chat.default_model so
  the chosen model is whatever the env / Setting cascade resolves to.

Verified by running `ANTHROPIC_MODEL=claude-haiku-4-5 OPENAI_MODEL=gpt-4o
bin/rails test test/models/chat_test.rb` — 16 runs, 0 failures
(previously 2 pre-existing failures + 0 from the new tests).

* fix(ai): address local review on Anthropic foundation

- Provider::Anthropic#supports_pdf_processing? bypasses prefix gate for
  custom endpoints, mirroring supports_model?
- Provider::Anthropic#initialize raises Error when custom_endpoint? AND
  model.blank?, parity with Provider::Openai
- stream_chat_response captures partial usage on mid-stream errors and
  records it via the new on_partial callback so chat_response can skip
  the duplicate error row in the outer rescue
- safe_accumulated_message swallows the secondary failure when the SDK
  cannot reconstruct a snapshot
- langfuse_client memoizes properly (||= instead of =) so repeated calls
  don't churn Langfuse instances
- MessageFormatter sorts tool_calls by created_at then id so the
  message array is deterministic across replays; skips tool_calls
  missing both provider_call_id and provider_id rather than sending
  `id: nil` and getting rejected by Anthropic
- Setting.anthropic_access_token default falls back through
  ENV["ANTHROPIC_API_KEY"].presence (was missing .presence, so an
  empty-string env value bled through)
- User#openai_configured? / #anthropic_configured? delegate to the
  Provider::* class methods — single source of truth
- Assistant::Responder renames the OpenAI-shape history builder
  conversation_history → openai_messages_payload so the kwarg name
  matches the local method name (messages: openai_messages_payload,
  conversation_history: chat_message_records)
- Assistant::Builtin stale-history comment updated to reference both
  builders

Adds a streaming chat_response test using ad-hoc subclasses of the
SDK event types so the case/when dispatch matches via is_a? without
stubbing class-level === behavior.

* test(ai): add Anthropic tool_use round-trip + multi-tool turn coverage

Addresses @jjmata's "worth confirming" note on PR #1983: tool-use turns
from prior assistant messages must round-trip correctly when retrieved
from the database.

- New `ChatParser → ToolCall::Function → MessageFormatter` test walks
  the full path: Anthropic response with a tool_use block →
  ChatFunctionRequest → ToolCall::Function.from_function_request →
  persisted on the AssistantMessage → MessageFormatter rebuild on the
  next turn. Asserts the original `tool_use.id` is preserved end-to-end
  as both `tool_use.id` and the paired `tool_result.tool_use_id`, and
  that the original `input` hash and serialized result content survive.
- New multi-tool assistant turn test confirms two tool_use blocks on a
  single assistant message render as two tool_use blocks followed by
  two paired tool_result blocks in a single user-role follow-up,
  matching Anthropic's required alternation.

Both tests exercise the existing PR1 code without behavior changes.

* test(ai): require "ostruct" explicitly in Anthropic provider tests

OpenStruct is moving out of Ruby's default load path (warning in 3.4+,
removed in 3.5+). Tests work today because ActiveSupport transitively
loads it, but that's incidental. Match the existing convention in
test/controllers/settings/hostings_controller_test.rb which explicitly
requires ostruct for the same reason.

* fix(ai): sanitize Langfuse warn logs, normalize tool_use.input, dedup history fetch

Addresses three open CodeRabbit findings on PR #1983.

- Provider::Anthropic Langfuse rescue branches no longer include
  `e.full_message` in `Rails.logger.warn`. `full_message` bundles the
  backtrace + cause chain and on some SDK error types includes the
  serialized request/response payload (prompt, model output). Logs
  now report `#{e.class}: #{e.message}` only. Three sites:
  create_langfuse_trace, log_langfuse_generation, upsert_langfuse_trace.
  Note: Provider::Openai has the same pattern (copy-pasted source) —
  harmonization deferred to a follow-up cleanup PR; this commit fixes
  only the Anthropic provider to keep PR scope tight.

- MessageFormatter#parse_arguments now coerces any non-Hash parsed
  result to `{}`. Anthropic's Messages API requires `tool_use.input`
  to be a JSON object (map); a stored ToolCall::Function record whose
  arguments parse to a scalar, bool, or array (corrupt row, legacy
  data, cross-provider bleed) would otherwise produce a payload the
  API rejects. Normal flow stores Hash arguments end-to-end so the
  fix is defensive — adds 2 tests covering scalar/array JSON strings
  and non-String non-Hash inputs.

- Assistant::Responder dedups the chat-history fetch. The previous
  layout fired two near-identical `chat.messages.where(...).includes(
  :tool_calls).ordered` queries per LLM turn (one for the OpenAI-shape
  payload, one for the raw-records kwarg). A new memoized
  `complete_chat_messages` fetches once; `chat_message_records` filters
  out the current message via `Array#reject`, `openai_messages_payload`
  iterates the cached array unchanged. One SQL query per turn instead
  of two. Memoization scope = single Responder instance (per LLM call),
  so cache invalidation is not a concern.

All 4370 tests pass (1 pre-existing libvips env error unrelated).
Rubocop + brakeman clean.

* fix(ci): replace sk-ant- prefixed test placeholders

Pipelock secret scanner pattern-matches `sk-ant-*` as a real Anthropic
API key and fails the PR security-scan check. Test stubs and
ClimateControl env values used `sk-ant-test`, `sk-ant-from-setting`,
`sk-ant-x`, `sk-ant-y` as obvious placeholders, but the scanner does
not care about value entropy.

Switched to `fake-anthropic-key-*` / `fake-token-*` strings so the
scanner stops flagging them. No production code touched, no behavior
change — Provider::Anthropic still accepts any non-blank token.

* feat(ai): add Anthropic batch ops + LLM cost ledger (2/5)

Implements auto_categorize, auto_detect_merchants, and
enhance_provider_merchants on Provider::Anthropic via forced tool calls,
plus the cost-ledger plumbing they need.

- Provider::Anthropic::AutoCategorizer, AutoMerchantDetector,
  ProviderMerchantEnhancer each define a single output tool whose
  input_schema mirrors the desired output, then force the model to call
  it via tool_choice: { type: "tool", name: ..., disable_parallel_tool_use: true }.
  Anthropic guarantees the tool_use.input matches the schema, so there
  is no JSON parsing fragility, no <think> tag stripping, and no
  json_object/json_schema fallback ladders.
- Concerns::UsageRecorder mirrors the OpenAI sibling but persists
  cache_creation_input_tokens / cache_read_input_tokens to dedicated
  columns instead of metadata.
- Migration adds cache_creation_tokens, cache_read_tokens (nullable
  integers) to llm_usages. OpenAI rows leave them null.
- LlmUsage::PRICING gains Claude 4.x rows (opus-4-7 $15/$75, sonnet-4-6
  $3/$15, haiku-4-5 $1/$5 per MTok). infer_provider returns "anthropic"
  for claude-* via the existing exact/prefix lookup.
- Provider::Anthropic#chat_response now persists cache columns directly
  rather than stashing them in metadata.
- 25-transaction batch cap mirrors the OpenAI provider so the cost
  ledger sees the same shape regardless of which provider ran a batch.

Tests cover the forced-tool-call path, null/None normalization,
case-insensitive merchant matching, the missing-tool_use error path,
and Anthropic-specific pricing + provider inference on LlmUsage.

Stacked on #1983 (PR 1/5). 3/5 PDF + vision next.

* fix(ai): attribute Bedrock model IDs to anthropic + clean nil enum

- LlmUsage.infer_provider now returns "anthropic" for Bedrock /
  Vertex shaped IDs (anthropic.* and anthropic/*), so cost-ledger
  filtering by provider stays correct even when no per-MTok rate is
  stored. Previously these IDs fell through to the "openai" default.
- AutoCategorizer drops the redundant nil sentinel from the
  category_name enum — the union type [string, null] already permits
  null, and some JSON Schema validators reject nil literals inside
  enum arrays.

* test(ai): require "ostruct" in Anthropic batch op tests

Same rationale as the PR1 ostruct fix — explicit require so the tests
don't depend on ActiveSupport's transitive load when Ruby 3.5+ removes
OpenStruct from the default load path.

* feat(ai): Anthropic native PDF processing (3/5)

Implements process_pdf and extract_bank_statement on Provider::Anthropic
using the native `document` content block — no rasterization, no text
pre-extraction.

- Provider::Anthropic::PdfProcessor classifies the document, summarizes
  it, and extracts statement metadata via a forced report_document_analysis
  tool whose input_schema mirrors the existing Provider::Openai output
  (document_type from Import::DOCUMENT_TYPES, summary, extracted_data).
- Provider::Anthropic::BankStatementExtractor returns the same
  { transactions, period, account_holder, account_number, bank_name,
  opening_balance, closing_balance } shape via report_bank_statement so
  downstream pdf_import code is provider-agnostic.
- Both attach the PDF as
  { type: "document", source: { type: "base64", media_type: "application/pdf", data: <b64> } }
  — Claude 3.5+ / 4.x accept this natively (up to 32MB / 100 pages).
  No pdf-reader, no pdftoppm, no chunking for typical statements.
- supports_pdf_processing? (introduced in PR 1) already returns true for
  claude-* models, gating process_pdf with a clear error otherwise.
- Cost ledger rows are persisted via the shared UsageRecorder concern,
  including cache_creation/cache_read tokens.

Tests verify the document block shape, tool_choice forcing, normalized
document_type for unknown classifications, transaction normalization
(date / amount / reference → notes), and the missing-tool_use error
path. Blank pdf_content raises before any client call.

Stacked on #1984 (PR 2/5). 4/5 pgvector RAG next.

* fix(ai): guard PDF size + surface bank-statement truncation

- PdfProcessor and BankStatementExtractor raise upfront when
  pdf_content.bytesize exceeds MAX_PDF_BYTES (32 MB, matching
  Anthropic's hard limit). Previously a 100 MB PDF would be
  base64-encoded (~133 MB) and packed into the JSON body before
  the API rejected it — peak heap ~270 MB per Sidekiq worker.
- BankStatementExtractor inspects response.stop_reason; when the
  model hit max_tokens it logs a warning and flags result[:truncated]
  so downstream callers know the transaction list may be incomplete.
- ISO date pattern added to statement_period_start/end schema in
  PdfProcessor so the model can't return "March 2026" — Anthropic
  enforces the regex via the tool's input_schema.

Tests cover the size guard (raises before any client.messages call),
truncated-result flagging, and the warning log path.

* test(ai): require "ostruct" in Anthropic PDF tests

Match the explicit ostruct require added in PR1/PR2 — same Ruby 3.5+
load-path reason.

* feat(ai): default Anthropic installs to pgvector RAG (4/5)

The provider-agnostic vector store stack (VectorStore::Pgvector + the
Embeddable concern) already shipped to main. This PR closes the
Anthropic loop:

- VectorStore::Registry.adapter_name now returns :pgvector when
  Setting.llm_provider == "anthropic" and no explicit
  VECTOR_STORE_PROVIDER override is set. Anthropic has no hosted vector
  store, so falling back to the local pgvector adapter is the only
  correct default. Explicit VECTOR_STORE_PROVIDER still wins.
- SearchFamilyFiles surfaces a longer message when no adapter is wired
  up — calling out pgvector + EMBEDDING_URI_BASE as the supported
  Anthropic-only path so the user is not stuck with an "OpenAI required"
  hint that is no longer accurate.

The Embeddable concern already pulls embeddings from
EMBEDDING_URI_BASE / EMBEDDING_ACCESS_TOKEN (with OpenAI as fallback),
so Anthropic installs point this at Voyage AI, a local Ollama instance,
or OpenAI embeddings — independent of the chat provider.

Tests cover the new default routing, the existing OpenAI default
staying intact, and explicit VECTOR_STORE_PROVIDER overriding the
Anthropic default.

Stacked on #1985 (PR 3/5). 5/5 settings UI + retention disclosure next.

* fix(ai): provision pgvector table when it is the default store

#1986 makes pgvector the default vector store for Anthropic installs, but
CreateVectorStoreChunks only ran when VECTOR_STORE_PROVIDER=pgvector was set
explicitly — so a fresh Anthropic-only install migrated without the
vector_store_chunks table and failed on uploads/searches.

Add VectorStore::Registry.pgvector_effective? as the single source of truth
for "is pgvector active?" (explicit env OR the Anthropic default), and a new
idempotent migration that enables the extension + creates the table whenever
pgvector is effective and the table is missing — covering fresh and
already-migrated installs without drift. Addresses Codex P1.

* fix(ai): provision pgvector table for Anthropic-default installs

Migration gated on raw VECTOR_STORE_PROVIDER==pgvector, so an
Anthropic-default install (which selects pgvector implicitly via
Setting.llm_provider without setting VECTOR_STORE_PROVIDER) skipped
table creation and failed later on a missing vector_store_chunks
relation. Route through VectorStore::Registry.pgvector_effective? —
the single source of truth already shared by the adapter selection.

Addresses Codex P1 review finding.

* fix(ai): provision pgvector chunks table on schema-load installs

The ensure-migration only helps db:migrate upgraders. Fresh installs go
through bin/docker-entrypoint's db:prepare, which loads schema.rb (the
conditional table can't be dumped there — it needs the vector extension)
and marks every migration applied without running it. An Anthropic-only
fresh install therefore selected the pgvector adapter but had no table,
failing with raw PG errors on first upload or search.

Two layers close it:

- VectorStore::Pgvector#ensure_schema! provisions the table idempotently
  on first use (mirrors CreateVectorStoreChunks; memoized; failures wrap
  in VectorStore::Error, which with_response turns into a clean failed
  response).
- VectorStore::Registry#build_pgvector now gates on
  VectorStore::Pgvector.available? (table exists, or extension present),
  so installs whose Postgres lacks pgvector entirely degrade to the
  assistant's provider_not_configured message instead of raising
  mid-chat.

Also resolves the schema.rb version conflict against main (keep the
branch's 2026_06_01_120000, on top of main's current tables).

* fix(ai): address review nitpicks on pgvector provisioning

- Registry: update the adapter doc comment to mention the
  Anthropic-to-pgvector default alongside the openai fallback.
- ensure_schema!: guard the DDL with if_not_exists instead of a Mutex.
  Adapter instances are built per call and never shared across threads,
  so the realistic race is two processes (web + Sidekiq) provisioning
  concurrently; IF NOT EXISTS makes the loser a no-op where a Mutex
  would only serialize threads inside one process.

6d22514c01 feat(vector-store): Implement pgvector adapter for self-hosted RAG (#1211)
* Add conditional migration for vector_store_chunks table

Creates the pgvector-backed chunks table when VECTOR_STORE_PROVIDER=pgvector.
Enables the vector extension, adds store_id/file_id indexes, and uses
vector(1024) column type for embeddings.

* Add VectorStore::Embeddable concern for text extraction and embedding

Shared concern providing extract_text (PDF via pdf-reader, plain-text as-is),
paragraph-boundary chunking (~2000 chars, ~200 overlap), and embed/embed_batch
via OpenAI-compatible /v1/embeddings endpoint using Faraday. Configurable via
EMBEDDING_MODEL, EMBEDDING_URI_BASE, with fallback to OPENAI_* env vars.

* Implement VectorStore::Pgvector adapter with raw SQL

Replaces the stub with a full implementation using
ActiveRecord::Base.connection with parameterized binds. Supports
create_store, delete_store, upload_file (extract+chunk+embed+insert),
remove_file, and cosine-similarity search via the <=> operator.

* Add registry test for pgvector adapter selection

* Configure pgvector in compose.example.ai.yml

Switch db image to pgvector/pgvector:pg16, add VECTOR_STORE_PROVIDER,
EMBEDDING_MODEL, and EMBEDDING_DIMENSIONS env vars, and include
nomic-embed-text in Ollama's pre-loaded models.

* Update pgvector docs from scaffolded to ready

Document env vars, embedding model setup, pgvector Docker image
requirement, and Ollama pull instructions.

* Address PR review feedback

- Migration: remove env guard, use pgvector_available? check so it runs
  on plain Postgres (CI) but creates the table on pgvector-capable servers.
  Add NOT NULL constraints on content/embedding/metadata, unique index on
  (store_id, file_id, chunk_index).
- Pgvector adapter: wrap chunk inserts in a DB transaction to prevent
  partial file writes. Override supported_extensions to match formats
  that extract_text can actually parse.
- Embeddable: add hard_split fallback for paragraphs exceeding CHUNK_SIZE
  to avoid overflowing embedding model token limits.

* Bump schema version to include vector_store_chunks migration

CI uses db:schema:load which checks the version — without this bump,
the migration is detected as pending and tests fail to start.

* Update 20260316120000_create_vector_store_chunks.rb

9e57954a99 Add Family vector search function call / support for document vault (#961)
* Add SearchFamilyImportedFiles assistant function with vector store support

Implement per-Family document search using OpenAI vector stores, allowing
the AI assistant to search through uploaded financial documents (tax returns,
statements, contracts, etc.). The architecture is modular with a provider-
agnostic VectorStoreConcept interface so other RAG backends can be added.

Key components:
- Assistant::Function::SearchFamilyImportedFiles - tool callable from any LLM
- Provider::VectorStoreConcept - abstract vector store interface
- Provider::Openai vector store methods (create, upload, search, delete)
- Family::VectorSearchable concern with document management
- FamilyDocument model for tracking uploaded files
- Migration adding vector_store_id to families and family_documents table

https://claude.ai/code/session_01TSkKc7a9Yu2ugm1RvSf4dh

* Extract VectorStore adapter layer for swappable backends

Replace the Provider::VectorStoreConcept mixin with a standalone adapter
architecture under VectorStore::. This cleanly separates vector store
concerns from the LLM provider and makes it trivial to swap backends.

Components:
- VectorStore::Base — abstract interface (create/delete/upload/remove/search)
- VectorStore::Openai — uses ruby-openai gem's native vector_stores.search
- VectorStore::Pgvector — skeleton for local pgvector + embedding model
- VectorStore::Qdrant — skeleton for Qdrant vector DB
- VectorStore::Registry — resolves adapter from VECTOR_STORE_PROVIDER env
- VectorStore::Response — success/failure wrapper (like Provider::Response)

Consumers updated to go through VectorStore.adapter:
- Family::VectorSearchable
- Assistant::Function::SearchFamilyImportedFiles
- FamilyDocument

Removed: Provider::VectorStoreConcept, vector store methods from Provider::Openai

https://claude.ai/code/session_01TSkKc7a9Yu2ugm1RvSf4dh

* Add Vector Store configuration docs to ai.md

Documents how to configure the document search feature, covering all
three supported backends (OpenAI, pgvector, Qdrant), environment
variables, Docker Compose examples, supported file types, and privacy
considerations.

https://claude.ai/code/session_01TSkKc7a9Yu2ugm1RvSf4dh

* No need to specify `imported` in code

* Missed a couple more places

* Tiny reordering for the human OCD

* Update app/models/assistant/function/search_family_files.rb
