Provenance had no system-level owner: ownership was only per-tree
(TreeMembership), so a self-hosted instance had no operator account and no
instance-admin surface. This adds one, declared by environment per the project's
twelve-factor rule.
- OWNER_EMAIL (comma-separated): the account(s) named here are instance owners.
Derived at request time — no DB column, no migration, can't drift from the env,
survives DB resets. is_instance_owner()/InstanceOwner dependency in api/deps.py.
- Ownership requires a VERIFIED email (independent of REQUIRE_EMAIL_VERIFICATION).
Registration is open, so without this an attacker could seize the role by
registering the owner address first; verification ties it to inbox control.
- GET /api/v1/admin/instance (owner-only): operational status — version, env,
user/tree counts, configured AI providers. Deliberately exposes no tree data
or PII: instance ownership is an operator role, NOT a privacy-engine bypass.
- /users/me reports is_instance_owner; frontend gains an owner-only /admin page
and a conditional sidebar link (server-enforced, not just client-hidden).
Found-and-fixed by an adversarial security review before merge: the
verified-email land-grab (above) and a frontend null-deref where the admin page
crashed on 401/5xx instead of failing closed.
Docs: .env.example + ARCHITECTURE (notes the not-a-privacy-bypass boundary and
the verified-email requirement). Tests: owner matching, the land-grab guard,
/users/me, and owner-only /admin. Suite 96 passing.

Extends the #215 abstraction:
- OpenAICompatibleLLMProvider / OpenAICompatibleEmbeddingProvider — one impl (via
the official openai SDK) covers OpenAI, xAI (api.x.ai/v1), Ollama
(…:11434/v1), OpenRouter, etc.; they differ only by base_url, key, and model.
- Registry factory: build_llm_providers() / build_embedding_providers() return
every provider whose credentials are configured, so you can run several
concurrently. get_llm_provider(name)/get_embedding_provider(name) select by
name, falling back to default_*_provider, then Null.
- Per-provider env config (ANTHROPIC_*, OPENAI_*, XAI_*, OLLAMA_*) +
DEFAULT_LLM_PROVIDER / DEFAULT_EMBEDDING_PROVIDER; documented in .env.example.
Defaults keep AI off (empty registry).
Embeddings now have real backends (OpenAI/Ollama), still separate from the LLM
since Anthropic offers no embeddings endpoint. Tests cover multi-provider
selection, default resolution, disabled-without-credentials, and null fail-loud.
Full suite 87 passed.
Relates to #215.

Adds the vendor-agnostic seam the AI assistant + match-ranking plug into:
- LLMProvider / EmbeddingProvider ABCs (base.py). LLM and embeddings are
SEPARATE abstractions — Anthropic has no embeddings endpoint, so each is
configured independently and either can be off.
- NullLLMProvider / NullEmbeddingProvider — the default; fail loud with a clear
"not configured" error so AI-off deployments don't silently no-op.
- AnthropicLLMProvider — first concrete LLM impl, via the official anthropic SDK
(default model claude-opus-4-8). A local provider (e.g. Ollama) would be
another subclass of the same interface.
- Factory in deps.py (get_llm_provider / get_embedding_provider) selects by
env (MODEL_PROVIDER / EMBEDDING_PROVIDER); documented in .env.example.
Providers are read-only text/vector producers — they never touch the DB, so the
"AI never writes autonomously" invariant (CLAUDE.md #1) holds; writes will go
through ChangeProposal (#214).
Tests: provider selection (null default, anthropic when keyed, fallback without
key) + null providers raise. 81 passed.
Closes#215

Backlog §2.10: registration issued a live session and email_verified_at was
written but never read, so an unverified user had full access and there was no
switch to require verification.
Add REQUIRE_EMAIL_VERIFICATION (default false). When true:
- resolve_session_user returns None for a user whose email_verified_at is null —
the single read-side gate covering every authenticated request, incl. the
session minted at registration.
- login raises 403 ("email not verified") instead of issuing a useless token.
Default false on purpose: self-hosts without SMTP, and accounts created before
this gate existed (email_verified_at null), must not be locked out. Operators
enable it once mail works and accounts are verified. Documented in .env.example.
Tests: default-off keeps unverified accounts working; on → register's session
won't resolve (401), login is 403, and after verify-email both work. 75 passed.

Media model + migration; an ObjectStore interface with an S3/MinIO (boto3) implementation behind the service layer. Upload (multipart) stores bytes in object storage + a metadata row (checksum, size, content-type, optional attach to person/event/source); list returns presigned URLs; delete is soft. Editor-gated, privacy-filtered, audited. 24 tests pass (object store faked).
Introduces the worker container (same image, 'python -m app.worker'): its first job is the scheduled 30-day soft-delete purge across tables + media object cleanup. Compose gains worker + S3 env on backend/worker; dev override builds the worker too.

Two tables (sessions, user_tokens) + migration; only token *hashes* are stored, so a DB leak yields no usable credential. Argon2id password hashing and token primitives in app/core/security. Config and .env.example gain session/cookie/token TTLs, app base URL, and SMTP settings (twelve-factor). Migration verified reversible (drops the token_purpose enum) and matches the models.

Phase 0 foundation. uv-managed FastAPI app (package=false, runs from source via uv run). Layered seams in place: app/api for routers, app/core for config (pydantic-settings, fully env-driven) and the async SQLAlchemy engine; service/repository/domain layers land with the data model.
Exposes /health (liveness) and /health/ready (Postgres reachability via SELECT 1, 503 on failure) so the deploy wiring is verifiable before any data model exists. Includes a liveness test and the resolved uv.lock. Ignore pytest/ruff/mypy caches.
