* fix(dreamer): threshold and time-guard semantics
Finding 2: filter count_stmt on documents.level == 'explicit' in
check_and_schedule_dream. Dreamer-created levels (deductive, inductive,
contradiction) are consolidation output, not input, and would otherwise
inflate the threshold count and create a feedback loop.
Finding 3 (code-level): relocate last_dream_at write from enqueue_dream
(enqueue.py) to process_dream (orchestrator.py), inside the
'if result is not None' block. Duplicate enqueues can no longer reset
the 8-hour time guard clock. Failed/never-run dreams don't advance it.
Success criteria: lenient (any non-null DreamResult counts). Pending
Vineeth confirmation — will adjust to strict/middle if requested.
Tests pending in follow-up commits.

* test(dreamer): threshold filter + last_dream_at relocation regression tests
Tests for Finding 2 and Finding 3 (code-level):
- TestThresholdFilter (tests/dreamer/test_dream_scheduler.py):
* Mixed levels below explicit threshold: 30 explicit + 40 deductive
+ 10 inductive → no trigger (core regression, buggy count would trigger)
* Explicit-only at threshold: 60 explicit → triggers
* Contradiction excluded: 100 contradiction + 10 explicit → no trigger
(confirms positive == "explicit" filter excludes all dreamer output)
- TestEnqueueDreamMetadataShape (tests/deriver/test_enqueue_dream.py):
* AsyncMock-patched update_collection_internal_metadata verifies
enqueue writes last_dream_document_count but NOT last_dream_at
- TestLastDreamAtCompletionWrite (tests/dreamer/test_dreamer_integration.py):
* Happy path: run_dream returns DreamResult → last_dream_at written
* Failure path: run_dream returns None → last_dream_at absent
* Exception path: run_dream raises → last_dream_at absent,
process_dream swallows exception (queue-processed semantics preserved)
Docstring on check_and_schedule_dream tightened: "document threshold"
-> "explicit-observation threshold" to reflect filter semantics.

* fix(dreamer): preserve last_dream_document_count in completion write
CodeRabbit caught this: update_collection_internal_metadata uses a
top-level JSONB `||` merge, so passing {"dream": {"last_dream_at": ...}}
replaces the entire "dream" subkey and drops last_dream_document_count
that was written by enqueue_dream.
Symptom: after every completed dream, the baseline drops to 0. Next
check_and_schedule_dream reads documents_since_last_dream as
current_count - 0 = current_count, so any collection with >= 50
explicit observations can re-trigger immediately once the 8h guard
expires, even with no new raw material.
Fix: read-modify-write. Fetch current collection, merge last_dream_at
into the existing "dream" dict, write the merged dict back. Preserves
sibling keys (current: last_dream_document_count; future-proof for
telemetry fields that might land in PR 4).
Regression test added to tests/dreamer/test_dreamer_integration.py:
pre-seeds {"dream": {"last_dream_document_count": 42}}, runs
process_dream, asserts both last_dream_at is written AND
last_dream_document_count == 42 is preserved.

* fix(dreamer): address CodeRabbit feedback on b89997c
- enqueue.py: read-modify-write preserves last_dream_at when writing baseline
- dream_scheduler.py: explicit-level filter on execute_dream count query
- test fixture: pin DOCUMENT_THRESHOLD and ENABLED_TYPES for stability
- integration test: timezone-aware assertion on last_dream_at
Regression test added for enqueue sibling-drop (symmetric to c8fe40a).

* fix(dreamer): session lookup symmetry + row lock on dream metadata RMW
- dream_scheduler.py: explicit-level filter on execute_dream session lookup
(baseline and session pick must agree on the same document set)
- crud.collection.get_collection: optional with_for_update flag for callers
that need serialized read-modify-write on internal_metadata
- enqueue.py + orchestrator.py: pass with_for_update=True on the RMW reads
to close the TOCTOU between concurrent enqueue and completion writes
Follow-up filed for jsonb_set-based nested updates (docs/factory/backlog/).

* fix(dreamer): explicit-only count on manual schedule_dream route
The third caller of enqueue_dream — POST /workspaces/{id}/schedule_dream —
was passing an all-levels document count as the baseline, breaking symmetry
with check_and_schedule_dream and execute_dream after Loop 2's filter fixes.
Filter the manual route's count to match.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
* docs(dreamer): document explicit-only invariant on enqueue_dream.document_count
Loop 3 follow-up on d76627a. The parameter's semantic tightened across Loop
2 (check_and_schedule_dream, execute_dream) and Loop 3 (schedule_dream route)
to "explicit-level count, used as the baseline," but the signature still read
"Current document count for metadata update." The next caller would have no
way to know from the function contract.
Docstring now spells out: (1) the value is explicit-only, (2) it's written
as last_dream_document_count, (3) it's the baseline that
check_and_schedule_dream subtracts from to compute
documents_since_last_dream, (4) passing a count that includes non-explicit
levels (deductive, inductive, contradiction) inflates the baseline and
suppresses the next scheduled dream.

* refactor(dreamer): rename current_document_count → current_explicit_count
Loop 3 follow-up on d4e10e3. After Loop 2's filter landed, the local in
check_and_schedule_dream held an explicit-only count but was still named
current_document_count — asymmetric with execute_dream's current_explicit_count
(line 201) and contradicting the filter on line 269 that produces the value.
Pure rename: three occurrences (definition at 271, subtraction at 274, log
extra key at 282). No test references. Naming-as-invariant alignment with
d76627a (query filters), d4e10e3 (parameter docstring), and Loop 1's local
rename in execute_dream.
The persisted JSONB key last_dream_document_count is the one remaining
drift-layer; filed as plastic-claudebook backlog item for a separate PR
with an intentional migration path.

* fix(dreamer): atomic guard-pair write + in-flight stampede defense
Loop 4 response to Vineeth's CHANGES_REQUESTED on PR #573.
The pre-Loop-4 enqueue-time write of last_dream_document_count was serving
double duty: rate limiter AND stampede latch. By arming the 8h guard the
moment a dream entered the pipeline, it implicitly blocked a second dream
from being scheduled during the in-flight window. Loop 3 relocated the
last_dream_at write to completion without moving its sibling baseline,
splitting the semantic pair and exposing the latch role that had lived
only in Vineeth's head.
Invariant (now pinned to check_and_schedule_dream's docstring): from the
moment a dream is scheduled until it completes or fails, no second dream
may be enqueued for the same (workspace, observer, observed) — and the
baseline count advances only when consolidation actually happened.
Changes:
- enqueue_dream: remove the last_dream_document_count write entirely and
drop the document_count parameter. enqueue no longer touches dream
metadata; the implicit stampede latch is replaced by an explicit
queue-backed defense.
- process_dream: extend the existing row-locked RMW to write both guard
fields atomically. Current explicit-doc count is recomputed inside the
locked block (not carried on DreamPayload) so the pair reflects the
actual consolidation moment.
- check_and_schedule_dream: query QueueItem for pending dreams on this
collection's work_unit_keys (mirrors uq_queue_dream_pending_work_unit_key)
before arming a timer. Uses queue state as source of truth rather than
reflecting it into metadata.
- Tests: two new coherence tests under TestGuardPairCoherence —
test_pending_queue_item_blocks_second_schedule walks the stampede timeline,
test_silent_failure_allows_retry_on_same_corpus verifies failed dreams
don't consume the baseline. Existing tests updated to the new contract.
* chore(dreamer): trim comment slop from loop-4 atomic pair work
Compress three verbose comments added in d24958d — the invariant itself
is captured in check_and_schedule_dream's docstring, so the inline
narrative restates what the code already says.
- dream_scheduler.py defense C block: 5 lines → 2
- orchestrator.py atomic pair write: 4 lines → 1
- enqueue.py docstring paragraph: 5 lines → 2
Net: +5/-14. Follows Eri's eef27be precedent on sillytavern-honcho PR #7.

* fix: Add JSON repair for truncated LLM responses across all providers and Gemini thinking budget support
LengthFinishReasonError from OpenAI-compatible providers (custom, openai, groq) was crashing the deriver
with 14k+ occurrences in production. The vLLM path already had repair logic but it was gated on
provider=="vllm", unreachable when routing through litellm as a custom provider.
- Extract shared _repair_response_model_json() helper for all providers
- Catch LengthFinishReasonError in OpenAI/custom parse() path and repair truncated JSON
- Add repair fallback to Anthropic and Gemini response_model paths
- Add repair fallback to Groq response_model path
- Pass thinking_budget_tokens to Gemini 2.5 models via thinking_config
- Add 14 tests covering repair paths for all providers and Gemini thinking budget
Fixes HONCHO-YC

* fix: tests
* refactor: rename thinking validator to reflect transport scope
_validate_anthropic_thinking_minimum only enforces the >=1024 rule for
Anthropic and no-ops for other transports, so the name was misleading
now that it's shared across ConfiguredModelSettings, FallbackModelSettings,
and ModelConfig. Renamed to _validate_thinking_constraints with a docstring
clarifying per-transport behavior. No logic change.
* fix(config): drop transport-specific thinking params when env override changes transport
_fill_defaults_for_nested_field previously preserved the default MODEL_CONFIG's
thinking_budget_tokens/thinking_effort across a transport override. This leaked
Gemini-family defaults (e.g. thinking_budget_tokens=1024) into OpenAI-transport
overrides, and the OpenAI backend then correctly rejected the unsupported param
at call time (OpenAI uses reasoning.effort, not a token budget).
The helper now strips thinking_budget_tokens and thinking_effort from the
default dict when the env override supplies a transport different from the
default's. Explicit thinking params in the override are preserved.
* fix(config): apply thinking-param strip to dialectic level merge too
DialecticSettings._merge_level_defaults does its own inline MODEL_CONFIG
merge (parallel to _fill_defaults_for_nested_field), so the previous fix
missed dialectic-level overrides. E.g. flipping
DIALECTIC_LEVELS__minimal__MODEL_CONFIG__TRANSPORT from gemini (default)
to openai still leaked the default thinking_budget_tokens=0 into the
openai config, which the OpenAI backend then rejected at call time.
The level-merge path now applies the same 'strip transport-specific
thinking params when transport changes' rule as the generic helper.
Added a regression test exercising the merge validator directly.
* refactor(llm): wire ModelConfig knobs through, prune clients.py migration leftovers
Three connected fixes to finish carving the LLM stack out of src/utils/clients.py
and into src/llm/:
1. Propagate ModelConfig tuning knobs into backend calls.
honcho_llm_call_inner built extra_params from only {json_mode, verbosity},
silently dropping top_p, top_k, frequency_penalty, presence_penalty, seed,
and operator-supplied provider_params from any ModelConfig. Thread the
selected config through ProviderSelection and merge
build_config_extra_params(selected_config) into extra_params; per-call
kwargs still win over provider_params defaults. Makes
_build_config_extra_params public as build_config_extra_params so
clients.py and request_builder.py share one translation. Adds
TestModelConfigExtraParamsPropagation covering OpenAI/Anthropic knob
propagation, provider_params passthrough, and per-call override
precedence.
2. Drop dead extract_openai_* duplicates in clients.py.
extract_openai_reasoning_content, extract_openai_reasoning_details, and
extract_openai_cache_tokens had no callers outside their own definitions
— the live implementations live in src/llm/backends/openai.py. -103
lines from clients.py.
3. Unify on ModelTransport, delete SupportedProviders.
The "google" vs "gemini" split forced a _provider_for_model_config
translation shim in two places. Replace all SupportedProviders usages
with ModelTransport, rename CLIENTS["google"] → CLIENTS["gemini"],
update provider branches + LLMError labels + reasoning-trace entries
accordingly. Trace JSONL now writes "provider": "gemini" instead of
"google" — consistent with the broader env-var rename cutover.
Also tidies up pre-existing basedpyright findings in tests/llm/test_model_config.py
(pydantic before-validator dict inputs + descriptor-proxy call).
ruff: clean. basedpyright: 0 errors, 0 warnings. Tests: 153/153 pass across
tests/utils/test_clients.py, tests/utils/test_length_finish_reason.py,
tests/llm/, tests/dialectic/, tests/deriver/.

* refactor(llm): finish the src/utils/clients.py → src/llm/ migration
honcho_llm_call_inner now delegates to request_builder.execute_completion
and execute_stream instead of re-implementing backend call scaffolding
inline. The new _effective_config_for_call helper carries per-call kwargs
(temperature, stop_seqs, thinking_budget_tokens, reasoning_effort) onto
the selected ModelConfig — or synthesizes a minimal config for the
test-only callers that pass provider+model directly. max_output_tokens
is zeroed on the effective config to preserve the current
"per-call max_tokens wins" semantic; honoring ModelConfig.max_output_tokens
is a separable correctness concern.
Side effect of routing through the new path: ConfiguredModelSettings'
thinking_budget_tokens validator now fires on synthesized configs.
test_anthropic_thinking_budget was asserting that a sub-1024 budget
propagated to Anthropic — bumped to 1024 to match what Anthropic actually
accepts.
Unified client construction. Promoted the cached client factories in
src/llm/__init__.py (get_anthropic_client, get_openai_client,
get_gemini_client, get_{anthropic,openai,gemini}_override_client) to
public API and added them to __all__. Promoted
credentials._default_transport_api_key → default_transport_api_key.
Deleted the duplicate _build_client and _default_credentials_for_provider
from clients.py; _client_for_model_config now falls through to the
public factories. CLIENTS dict and _get_backend_for_provider stay as the
mockable seam for the ~50 patch.dict(CLIENTS, {...}) test call sites.
Wired operator-configurable Gemini cached-content reuse end-to-end.
PromptCachePolicy moved from src/llm/caching.py into src/config.py so
ModelConfig can reference it as a field without a circular import;
caching.py re-exports the name for existing imports. Added
cache_policy: PromptCachePolicy | None on ConfiguredModelSettings,
FallbackModelSettings, ResolvedFallbackConfig, and ModelConfig.
resolve_model_config, _resolve_fallback_config, and
_select_model_config_for_attempt copy the field through.
honcho_llm_call_inner passes effective_config.cache_policy into
execute_completion / execute_stream, so operators opt in via
e.g. DERIVER_MODEL_CONFIG__CACHE_POLICY__MODE=gemini_cached_content
and the selection actually fires instead of sitting on a dead path.
New regression test test_cache_policy_reaches_gemini_backend asserts the
PromptCachePolicy object reaches the Gemini backend's extra_params.
ruff + basedpyright: clean. Tests: 154/154 pass across
tests/utils/test_clients.py, tests/utils/test_length_finish_reason.py,
tests/llm/, tests/dialectic/, tests/deriver/.

* refactor(llm): move all LLM orchestration into src/llm/ and delete clients.py
The 1624-line src/utils/clients.py has been carved up into focused modules
under src/llm/ and deleted. There is now one golden path for LLM
orchestration and no dual entrypoint.
New module layout:
src/llm/
__init__.py thin stable re-export surface
api.py public honcho_llm_call with retry + fallback + tool
loop delegation
executor.py honcho_llm_call_inner (single-call executor); bridges
to request_builder.execute_completion / execute_stream
tool_loop.py execute_tool_loop + stream_final_response, plus
assistant-tool-message and tool-result formatting
runtime.py AttemptPlan dataclass (replaces the loose
ProviderSelection NamedTuple), effective_config_for_call,
plan_attempt, per-retry temperature bump, attempt
ContextVar
registry.py single owner of CLIENTS dict + cached default and
override SDK-client factories + backend/history-adapter
selection + high-level get_backend(config)
conversation.py count_message_tokens, tool-aware message grouping,
truncate_messages_to_fit
types.py HonchoLLMCallResponse, HonchoLLMCallStreamChunk,
StreamingResponseWithMetadata, IterationData,
IterationCallback, ReasoningEffortType, VerbosityType,
ProviderClient
request_builder.py low-level request assembly (ModelConfig → backend
complete/stream); no longer owns credential resolution
credentials.py default_transport_api_key, resolve_credentials
caching.py gemini_cache_store; re-exports PromptCachePolicy
from src.config
backend.py Protocol + normalized result types
history_adapters.py provider-specific assistant/tool message shapes
structured_output.py
backends/ AnthropicBackend, OpenAIBackend, GeminiBackend
handle_streaming_response had no production callers; it is deleted. The
three tests that used it now drive honcho_llm_call_inner(stream=True,
client_override=...) directly, which exercises the same code path the
public API uses.
Dead credential passthrough removed. The ProviderBackend Protocol and
all three concrete backends no longer accept api_key / api_base — those
are baked into the underlying SDK client at registry construction time
and were being del'd everywhere they appeared. request_builder also
stops resolving and forwarding them.
Client construction is unified. The cached default-client factories
(get_anthropic_client, get_openai_client, get_gemini_client) and override
factories (get_*_override_client) are promoted to public API; the
module-level CLIENTS dict populates from them and remains the
patch.dict(CLIENTS, {...}) mocking seam tests rely on. Old duplicate
helpers (_build_client, _default_credentials_for_provider) are gone.
default_transport_api_key is promoted to public.
Application imports now come from src.llm (dreamer, dialectic, deriver,
summarizer, telemetry-adjacent tests). No code imports from
src.utils.clients anywhere in the repo.
ruff: clean. basedpyright: 0 errors, 0 warnings. Tests: 1013/1013 pass
across the entire non-infra test suite (excluding tests/unified,
tests/bench, tests/live_llm, tests/alembic).

* fix(llm): sanitize tool schemas for Gemini's function_declarations validator
Gemini's native-transport function-declarations validator accepts a narrow
subset of JSON-Schema / OpenAPI: type, format, description, nullable, enum,
properties, required, items, minItems, maxItems, minimum, maximum, title.
Anything else — additionalProperties, allOf, if/then/else, $ref, anyOf,
oneOf, $defs, patternProperties — triggers an INVALID_ARGUMENT 400 at call
time.
Our agent tool schemas in src/utils/agent_tools.py use several of those
(additionalProperties: false, allOf + if/then conditionals) because they
were authored for OpenAI strict-mode + Anthropic, which need the richer
vocabulary. GeminiBackend._convert_tools was passing them straight through.
Add _sanitize_schema(): walks the parameters tree and drops unsupported
keywords while preserving semantics for the keywords that hold user data
(properties maps field-name → sub-schema; required / enum are lists of
literals; items is a single sub-schema). Other backends are untouched and
continue to receive the full strict schemas.
Regression tests:
- test_gemini_sanitize_schema_strips_unsupported_keywords: confirms
additionalProperties, allOf + if/then, and $defs are stripped at nested
levels while legitimate fields survive.
- test_gemini_convert_tools_sanitizes_parameters_schema: end-to-end
_convert_tools output has no forbidden keys.
