Lands the lean-SDK direction (boocode_code_review_v2 §1 #9) behind a flag.
Adds @anthropic-ai/claude-agent-sdk@0.3.159 (Commercial Terms, runtime dep).
- PostgresSessionStore: clean-room impl of the SDK's real SessionStore type
over a new claude_session_entries table. Typechecks against the SDK type;
8 DB-integration tests.
- ClaudeSdkBackend (implements AgentBackend): one warm query() per (chat,claude)
in streaming-input mode via a pushable async-iterable pump, sessionStore +
resume continuity, pure mapSdkMessage->AgentEvent, session_id from init,
usage/cost onto agent_sessions (backend CHECK gains 'claude_sdk').
- Routing env-gated by CLAUDE_SDK_BACKEND (default off) -> PTY path UNCHANGED.
- Built against real SDK 0.3.159 types (install paid off: partial=stream_event
needing includePartialMessages, MessageParam, result error arm).
- Fix latent test-infra deadlock: serialize DB suites (fileParallelism:false).
Coder 269 passing default / 290 with DB; tsc clean vs SDK types; builds clean.
LIVE pump + resume + actual claude turn need a host smoke (CLAUDE_SDK_BACKEND=1
+ claude binary + auth). zod peer-dep wants ^4 (workspace 3.25). Builds on v2.7.4.

Fix: getProviderSnapshot returned synchronous installed:false 'loading' entries on a cache miss (v2.5.5/Phase 2), which AgentComposerBar filters out — with the Phase 5 client poll not yet built, a single fetch stranded on 'loading' and the picker showed no providers. It now awaits the build and returns terminal entries; the sync loading-return is deferred until Phase 5. Builds stay fast via the tier-2 cold-probe skip.
Feature: wire the v2.3 config schema's models/additionalModels — buildResolvedRegistry carries them onto ResolvedProviderDef (models replace, additionalModels merge) and provider-snapshot applies them to every ready model list, so /data/coder-providers.json can edit any provider's models with no code change. Claude staticModels bumped from the stale 2-entry list to opus/sonnet/haiku latest-aliases + pinned claude-opus-4-8 / claude-sonnet-4-6 / claude-haiku-4-5-20251001 (passed verbatim to claude --model). +2 tests (109 total).

Checkpoint of in-progress backend work present in the tree, not authored this session: auto_name, inference tool-phase/turn, secret_guard, provider-registry, plus a new agent-allowlist test (7 tests, passing).

- BooCoder moves from Docker to host systemd service (boocoder.service)
- Agent dispatch (ACP + PTY) switches from SSH to direct spawn/exec
- SSH helpers marked @deprecated (kept for one release cycle)
- Provider registry (5 providers: boocode, opencode, goose, claude, qwen)
- Agent probe with direct which/exec + model discovery (qwen settings, static claude models)
- GET /api/providers route with installed status, models, transport fallback
- ProviderPicker frontend component in CoderPane header
- External provider messages route through tasks row instead of inference enqueue
- Smart scroll: MessageList only auto-scrolls when near bottom (150px threshold)
- DB: available_agents gets models, label, transport columns
- Bug fix: loadContext SELECT includes allowed_read_paths
- Bug fix: cap hit sentinel inserted before buildMessagesPayload
- docker-compose.yml: boocoder service commented out, BOOCODER_URL env var added
- CLAUDE.md: updated docs for systemd, provider registry, JSONB gotcha, loadContext
