* fix(dream): ground commit messages and cursor advance in the real git diff
Dream consolidation could emit a /dream-log audit record that did not match
the actual file changes: build_dream_commit_message appended the LLM's
unverified resp.content, dream_run_completed only checked the stop reason, and
file contents were deliberately omitted from the prompt. The combination let a
single-turn self-report become the durable audit record.
- gitstore: add summarize_working_tree() — a structured, machine-derived
summary (per-file +N/-M, totals, capped unified diff) of working-tree
changes vs HEAD. Pure filesystem/git ground truth, never LLM narrative.
- memory: build_dream_commit_message now takes the diff body instead of resp;
dream_content_diff() exposes the real delta over SOUL/USER/MEMORY.md only
(excludes .dream_cursor so cursor writes aren't mistaken for edits);
build_dream_prompt embeds current file contents so the model edits reality,
not a stale mental model.
- builtin/cli: both Dream paths now compute the diff, gate cursor advance on
a non-empty delta (no-op runs no longer swallow history), and commit with
the diff-grounded message. Non-git workspaces fall back to the completion
check.
- dream.md: document that contents are embedded, and add a chain-of-
verification guardrail so the model's summary cannot claim unmade edits.
A regression test proves a lying resp.content never reaches the audit log
while the real diff does.
* fix(dream): mark non-UTF-8 memory files as binary in diff summary
Address review feedback (Q1 on PR #4673): summarize_working_tree read
working-tree files with errors="replace", which would emit U+FFFD
replacement chars into the audit record if a memory file ever held
invalid UTF-8 — misrepresenting the diff it is meant to make truthful.
Switch to errors="strict" and catch UnicodeDecodeError: a non-UTF-8
(or binary/corrupt) file is now recorded as "{path}: binary or
non-UTF-8 file changed" and omitted from the unified diff, so the
audit record stays honest. An empty diff block is also suppressed when
all changes are binary.
Adds a defensive regression test asserting no replacement char leaks.
maintainer edit: update the existing transient retry tests for reconnect-first behavior and keep structured retry-failure coverage in the focused MCP transient suite.
maintainer edit: cron is also a trigger source, so keep the new CLI-delivered source explicitly named as local trigger across backend, WebUI, docs, and tests.
maintainer edit: remove the _last_compacted_at maintenance state, gate idle compaction on whether a session still has a removable tail, and sort WebUI sessions by the latest visible transcript activity.
Replace the tuple(list[dict], int) return of
Session.retain_recent_legal_suffix with a named RetentionResult
dataclass that exposes retained, dropped,
already_consolidated_count, and new_last_consolidated fields.
The tuple return was easy to misuse because the second value only
made sense relative to the first and the old last_consolidated
cursor. The named fields make the archive-skip semantics explicit
at every call site.
No behavior change. All existing tests pass unchanged in semantics.

Treat max_messages as a last-resort replay guard now that consolidation and idle auto-compact own normal history reduction. Raising the default avoids frequent sliding-window prefix churn in moderate conversations without adding a new cache-policy knob.
Combine malformed tool-call handling with placeholder filtering and a
no-tools fallback so a relay that returns tool_use blocks with null
id/name/input can no longer crash a turn or permanently wedge a session.
Adapted to the ContextGovernor architecture (context governance now lives
in nanobot/agent/context_governance.py, not runner.py):
- ToolCallRequest.has_valid_name(): single source of truth for "usable
name" (non-empty string).
- tool_hints.format_tool_hints(): skip tool calls with a non-string/empty
name instead of raising AttributeError on the whole turn.
- ContextGovernor.strip_placeholder_assistant_messages() and
strip_malformed_tool_calls() (plus the _tool_call_name_is_valid helper):
history-cleaning staticmethods invoked at the START of
prepare_for_model() — strip_placeholder, then strip_malformed, then the
existing drop_orphan/backfill chain. Both only repair the model-facing
copy and leave persisted history untouched (return a copy, or the same
list when nothing changes). Also wired into runner's minimal-repair path.
- AgentRunner._drop_malformed_tool_calls(): returns
(dropped, all_dropped, original_finish_reason); clears finish_reason to
"stop" when all calls are dropped.
- AgentRunner._malformed_tool_call_retry_messages() + _request_model
malformed_retry flag: when an all-dropped tool_calls response comes back,
retry once with a corrective note; if the retry STILL comes back
all-dropped, fall back to _request_no_tools for graceful text degradation.
Tests for the history-cleaning methods live with ContextGovernor in
tests/agent/test_runner_governance.py; response-layer and tool-hint tests
stay on AgentRunner / tool_hints.

Extract model-facing context governance from AgentRunner.
Only compact in-flight tool results when the model request is over budget, keep compacted IDs stable within a turn, and allow the newest result to be compacted as a last resort when it is the remaining source of overflow.
Add fail_on_tool_error to AgentDefaults and wire it through
AgentLoop -> SubagentManager -> AgentRunSpec.
Previously hardcoded to True in SubagentManager._run_subagent.
Now configurable via config.json with default True for backward
compatibility. When set to False, subagents can retry on minor
tool errors instead of immediately failing.
Changes:
- nanobot/config/schema.py: add fail_on_tool_error field (default True)
- nanobot/agent/subagent.py: accept and forward fail_on_tool_error
- nanobot/agent/loop.py: pass config through to SubagentManager
- tests/agent/test_subagent.py: add regression test

When dream.enabled is false, the Dream cron job never runs, so the
dream cursor (.dream_cursor) stays at its initial value (0). This
causes read_recent_history_for_prompt() to treat every history entry
as unprocessed, injecting the full chat history into every system
prompt and growing without bound.
Fix: fast-forward the dream cursor to the latest history entry at
gateway startup when Dream is disabled.
The onboard wizard dispatched field handlers by bare field name, so
WebSearchConfig.provider was hijacked by the LLM-provider handler and
showed LLM providers instead of search engines. Keenable was also never
wired into the CLI wizard when it landed in the WebUI.
- Add a single source of truth for selectable search providers
(SEARCH_PROVIDER_OPTIONS in web.py); WebUI settings now import it.
- Add a WebSearchConfig-aware search-provider picker to the wizard and
resolve handlers by (model type, field name) so the LLM and search
provider fields no longer collide.

maintainer edit: native reasoning streams can split <thinking> wrapper tags across chunks. Buffer the stream and emit only cleaned incremental reasoning so raw partial tags do not reach WebUI.
maintainer edit: move duplicate tool_use history repair out of AgentRunner and into Anthropic message conversion, reusing the OpenAI-compatible queue-mapping approach locally without broadening the shared runner path.
maintainer edit: remap duplicate tool_use/tool_call ids instead of dropping later calls, so Anthropic-compatible providers that reuse ids for distinct parallel tool calls keep all requested work while still sending unique ids.
Anthropic rejects any request where two tool_use blocks share an id
("messages.N.content.M: tool_use ids must be unique"). A mis-assembled
stream could surface the same tool_use block twice in one assistant turn;
the runner persisted it verbatim, so the malformed message was re-sent on
every subsequent turn and permanently bricked the session — the agent
silently stopped replying.
Fix at two layers:
- AnthropicProvider._parse_response: drop duplicate tool_use ids (keep
first) as the response enters nanobot, so corruption is never persisted.
- AgentRunner._dedup_tool_calls: a new context-governance pass that dedupes
assistant tool_calls and tool results by id before each send, healing any
history that was already corrupted.
Add regression tests covering both the dedup and the no-op fast path.
