Post-coordination-removal sweep: the coordination wire protocol
(AgentRequest, AgentResponse, DelegationIntent, CoordinationResult,
DelegationReason, TaskComplexity, ToolCallRecord, AgentTimeoutError,
AgentUnavailableError, DelegationError) had zero importers left in
src/ - only its own test module. AgentError stays (raised by
run_librarian, mapped to user-safe failures by delegation.py).
Also drops the stale coordination.py line from the README tree.
Import-cycle sanity: python -c 'import src.main' passes.

Phase A review minors:
- Coverage note: source_status (when present) is now used exclusively;
the source_counts-absence fallback only considers the optional legs
the request explicitly enabled (web/documents/volatile). library-desk
computes source_counts from the final top-N fused results only, so
absence of the always-on vector/graph legs is normal ranking behavior
- the old heuristic warned on virtually every healthy search
- update_wiki_page: the empty-list tags sentinel (leave unchanged) made
clearing all tags impossible; pass exactly ["__CLEAR__"] to send an
empty tag list, documented in the docstring for the local model
- Text-delegation parallel fallback: zip(..., strict=True) with an
explicit count-mismatch guard so results can never be silently
attributed to the wrong agent

One delegation implementation remains (src/agents/delegation.py).
Removed, after verifying zero live importers post-Phase-A/B:
- src/agents/coordination.py: CoordinationEngine, duplicate
delegate_to_librarian, AGENT_EXECUTORS/AGENT_STREAM_EXECUTORS
(only importer was its own test module)
- run_librarian_stream: documented-broken path (Ollama streaming +
tool call bug, PydanticAI #1292/#2256), only called by the deleted
coordination engine
- stream_delegate_to_* wrappers + STREAMING_DELEGATION_WRAPPERS and
the never-parsed __DELEGATION_RESULT__ marker in delegation.py
- HouseholdRegistry.get_streaming_delegation_tools() (no callers)
- tests/agents/test_coordination.py and the wrapper/stream tests
Note: the STREAMING_DELEGATION_WRAPPERS import in
src/responses/streaming.py was already removed by Phase A (7ce1c1a);
nothing to delete there.

LibraryDeskClient._resolve_user only enforced non-empty: an explicit
user argument to any tenant-scoped method bypassed tatlock's tenant
guard entirely and went straight to library-desk, and padded values
were sent un-stripped on the wire.
Route the explicit-arg path through the same apply_tenant_guard() used
by context resolution and strip whitespace before the empty check, so
a non-production environment can never send the production tenant (or
a sanitization-collision variant) to library-desk, regardless of how
the user was supplied. Defense in depth - no in-repo caller passes an
explicit user today.

Library-desk is removing its server-side default user, so a request
without an explicit tenant will 422 after its next deploy:
- New client-level _resolve_user() resolves the tenant (explicit arg
or request context) and raises ValueError on an empty/whitespace
value BEFORE any bytes hit the wire; all 15 tenant-scoped methods
use it
- extract_content / extract_content_batch now accept and send the
user (query param), matching the rest of the API surface
- search_web no longer falls back to a phantom "tatlock-librarian"
tenant; it sends the resolved user
- health_check stays user-less (public, not tenant-scoped)
Tests: parametrized sweep pins the wire contract (user present in
params or payload) for every tenant-scoped method, for both context
and explicit users; empty-tenant calls are asserted to fail without
any HTTP call; the recorded-fixture hybrid contract test now pins
user as an explicit query param.

- delegate_to_* now receives a trimmed conversation history (last ~6
turns, 500 chars/turn) as context on both live direct-delegation
paths (streaming and steward non-streaming), via new
build_delegation_context helper
- _stream_direct_delegation restructured as an async generator: the
butler 'start' think message streams BEFORE the expert runs and the
success/error message right after it finishes, instead of all
messages arriving after the research completed

Ollama's OpenAI-compatible API mishandles anyOf[X, null] parameter
schemas. update_wiki_page (content/title/tags/description) and
smart_create_wiki_page (path) now use empty-string/empty-list
sentinels translated to None inside the tool, following the
biographer pattern from 9d7ce39.
Adds a snapshot test that walks every registered librarian tool's
emitted JSON schema and fails on any anyOf[..., null].

- 2-attempt short-backoff retry for GETs and the read-only
POST /query/* and /rag/search endpoints only; wiki writes are never
retried (duplicate-page risk)
- honor the defined-but-ignored LIBRARY_DESK_TIMEOUT config instead of
hardcoded 60s/30s per-call values
- hold ONE shared httpx.AsyncClient per librarian run via
library_client_session (contextvar), instead of constructing a
client per tool call; nested sessions are no-ops and custom targets
still get their own client
- read tools raise ModelRetry on transient HTTP errors (transport
errors, 5xx, 429) so Agent(retries=2) engages; write tools keep
returning safe failure messages

- add LIBRARIAN_TIMEOUT config (default 180s) and enforce it with
asyncio.wait_for inside delegate_to_librarian, covering the live
paths (steward direct delegation and SSE streaming) that had no cap
- timeouts fail honestly: success=False with a curated butler sentence,
detail in logs
- set an explicit timeout on TatlockOllamaProvider's AsyncOpenAI client
from OLLAMA_TIMEOUT instead of the SDK default (~600s per LLM call)
- remove the contradictory unused 60s default from
AgentRequest.timeout_seconds; coordination falls back to the
configured budget
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- parse source_counts into HybridRAGResponse and additively parse the
shared-contract source_status/degraded fields when present (absence
tolerated, so deploy order between tatlock and library-desk never
matters)
- hybrid_search appends a one-line coverage note when a leg reported
'failed' (or degraded is set), falling back to inferring silent legs
from source_counts on older library-desk versions
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
- run_librarian / run_librarian_stream raise AgentError instead of
returning/yielding error text as normal output; detail stays in logs
- delegate_to_* wrappers now put a curated butler-toned sentence in
DelegationResult.output on failure and never expose str(e), so
streaming's error branch is reachable and honest
- _execute_single_delegation propagates success; direct delegation only
records delegate_to_* as called when the expert actually succeeded
- librarian tools return user-safe messages instead of
'Error searching: {e}' strings that leaked internal URLs into
synthesis; coordination stream errors are curated as well
- ruff cleanups (TYPE_CHECKING forward refs, B904, unused locals) in
the touched files to keep them lint-clean

The client parsed field names the live library-desk service never
returns, so every result rendered as "unknown (score: 0.00)":
- source_type/sources -> source + sources (icons key off sources values)
- rrf_score -> score
- context -> formatted_context
- related_dossiers are per-result; top level aggregates unique titles
- synonyms live inside the keywords dict as a {term: [synonyms]} map
Also stop sending zero limits (service 422s on limit < 1); disabled
legs now rely on the enable_* flags with limits clamped to >= 1.
Adds a recorded live response as a fixture plus contract tests that
pin the mapping (non-unknown sources, non-zero scores, icon coverage).

Rolls back the claudification backend preference: PREFER_CLOUD_BACKEND now
defaults to false, resolve_backend() picks Ollama first and uses Claude when
explicitly preferred or when the new Ollama startup health check fails. The
Steward retries mid-request failures on the other backend in both directions.
Also hardens the fallback itself: Anthropic SDK imports are lazy so a broken
anthropic package degrades to Ollama-only instead of crashing at import time
(root cause of the production outage since April), anthropic is pinned to a
pydantic-ai-1.27-compatible range, ANTHROPIC_MODEL defaults to claude-sonnet-5
(sonnet-4-20250514 retired 2026-06-15), sampling parameters are stripped from
Claude calls (Sonnet 5 rejects them), and the Steward timeout is configurable
(STEWARD_TIMEOUT, default 60s) since gemma4 needs ~35s warm for analysis.
