Unparseable (_raw) args now get a truthful error: cut-off-by-output-limit says
'smaller pieces', bad JSON says 're-send with declared parameters'. Raw junk is
shrunk before entering history so replays can't teach the model the _raw shape.
Anthropic default max_tokens 16k -> 32k so typical report files fit outright.
Fact strip: 'OpenWorker installs its own verified copy from <publisher>' replaces
supply-chain jargon. On decline the engine re-resolves — a copy the user installed
themselves is handed to the agent as theirs, not treated as a refusal.
Registry metadata (version, publisher, checksum) moves to a distinct fact strip.
Decline button renamed to say the run continues; reason capped to one sentence.
Sidecar inherits the login shell's env; toolchain resolves absolute paths with pinned
installs; request_tool replaces the 'tool missing -> STOP' instruction that hid a check.
Minimal engine footprint: a checkpoint at each iteration top (between tool
turns and before a new turn), the usage signal captured per round-trip
(context_tokens; chars/4 estimate when never reported), and
_outbound_messages consulting the boundary. The summarizer runs off-loop
through the normal provider router, so the Settings model pin is just an
id.
Failure policy per spec: retry once in both modes; attended sessions get
the Retry / Trim-oldest-10% prompt (via the ask_user plumbing, gated by an
is_attended callback the WS surface wires); unattended runs auto-trim and
continue — never parked on internal bookkeeping. Raw context-overflow 400s
from the main model route into the same policy, progress-guarded so a
still-overflowing model terminates in the error path.
CompactionState persists on the session record (new sqlite column, same
defensive parse as grants), so reloads keep the compacted view. A
persisted compacted notice + a new COMPACTED event mark the spot for
the GUI divider (rendered in commit 3).
Options accept {label, description, recommended, preview} objects (plain
strings unchanged — old sessions render as today's pills), and `questions`
groups up to 4 questions into one call, rendered as a stepper via the
header chips. Any option preview switches the card to a two-pane layout:
options left, monospace pane right, following hover/focus.
Grouped calls resolve with a JSON map keyed by header-or-question and
return {answers: {...}} to the agent (single stays {answer: ...});
a grouped item's first question doubles as its title/options so channel
mirrors and legacy surfaces degrade sensibly. Channel buttons use option
labels; grouped items mirror as text with the open-the-app hint.
Normalized TokenUsage (input/output/cache split) captured in every provider's
stream and complete paths, persisted as an assistant-message sidecar and sent
on the assistant_message event; matrix gains verified context-window sizes.
Switch notices no longer consume the retry guard or hide the button.
Error, switch model, Retry is the intended recovery path; retry runs on the new model.
New reasoning_delta event; traces persist as a display sidecar stripped from provider feeds.
Sources: compat vendors' reasoning_content and Gemini thought summaries (include_thoughts).
Live-verified on GLM via Together and Gemini 3; Gemini tool loops stay healthy.
Picker stays live for the session; switches persist a model_switch notice (§17 revised).
Rebinds refused mid-turn; images become placeholders for non-vision targets at send time.
Signatures ride the assistant message as a _gemini sidecar and are reattached in tool loops.
Thought-flagged parts are filtered from answer text; foreign sidecars stripped on the OpenAI wire.
Live-verified both Gemini 3 models end-to-end; without the echo they 400 on every tool loop.
Engine appends a display-only notice message on error/interrupted; providers never see it.
New retry frame re-runs a failed turn with no new user message, guarded on the error tail.
GUI renders persisted notices on reload and a Retry button on the trailing error.
GUI flushes the streaming buffer into a durable item on interrupted/error.
Engine persists partial text on the provider-error path like the stop path.
e2e red-green verified; full suites pass.
Stream drops between chunks (+ the pre-first-token wait); pending approvals/questions/plans resolve as interrupted.
Running shell commands die via an executor interrupt hook; skipped tool calls still get results (no orphans).
Also fixes delete_session calling a nonexistent engine.interrupt().
