fix(operator): activation reliability and failure UX — canary, teardown, errors, markdown, input - #143
Merged

Conversation
Activating a read_write operator failed reproducibly against Claude Sonnet 5:
Write canary did not pass (unknown): The operator did not attempt the
descriptor-patch write this probe looks for.
The operator was fine. Server logs show it called readAgentDescriptors and
answered normally; the tool it was meant to call (patchDescriptor) was present
-- the granted set is 23 read + 24 write = the 47 httpcall tools the backend
discovered. It listed the agents, then replied in prose instead of writing, and
the probe's "unknown" outcome deleted it.
That is not the model misbehaving. Asked to pick "any ONE" agent and rename it,
with no stated reason, stopping to ask which one is the correct response -- the
operator's own system prompt hardens it against loosely-specified instructions.
The probe was reading good behaviour as a failure.
Two changes:
1. The prompt is now built around the RESOLVED tool name (already looked up for
pause-detection, so no new failure mode), names the FIRST agent instead of
"any ONE", states that a clarifying question fails the test, and says the
interception is the expected outcome so the model has no reason to seek
approval before acting. Far more reliable -- but still an LLM choosing a
tool, so it cannot be made deterministic by prompt alone.
2. "unknown" and "fail" no longer report identically. Both still roll back --
write tools behind an unverified gate must not stay deployed either way --
but:
fail -> "The approval gate did NOT hold", and explicitly does NOT
suggest retrying.
unknown -> "Could not verify the approval gate - this is not evidence that
it is broken", plus a way forward (retry, or read-only, which
skips the probe entirely).
Reporting an unproven gate as a broken one sent admins hunting a security
problem that had not been demonstrated, and left them with no operator and
no next step.
Three existing tests pinned the old wording and were updated to assert the
property rather than the phrase. New coverage: the prompt names the tool and
drops the ambiguity, and the two outcomes produce distinguishable, actionable
messages. 5135 tests pass; tsc -b clean.
Does NOT fix the deeper issue: verification still depends on an LLM choosing to
call a tool, and the pass-through path still renames a real agent for real.
Both need a deterministic, non-destructive probe -- ideally classifying a
synthetic request through the backend gate with no model and no write.
…le-line input
Four defects found by using the operator end to end, all Manager-side.
1. Deactivating/resetting the operator showed a 409 for a successful teardown.
The backend refuses to undeploy an agent with active conversations, and the
admin's own operator chat IS one -- so using the operator at all made the
kill switch 409, with the TEXT_PLAIN explanation discarded. resetOperator
swallowed it and worked anyway (red request on success); deactivateOperator
failed outright. Both now pass endAllActiveConversations=true: the
conversations ended are this operator's own, and the admin is explicitly
shutting it down.
2. A turn that fails without a stream-level error left an empty bubble and no
explanation. The backend emits task_failed for the failing step, streams no
tokens, and closes the stream normally; the admin had to read the server
log to learn the turn failed at all (seen live: provider rejecting the
stored temperature). The done handler now surfaces the failing step and its
redacted summary as the chat error -- only when nothing streamed, nothing
paused, and a step actually failed, so recovered turns and pauses stay
quiet.
3. Step list noise and the bare UNKNOWN badge. httpcalls joins
INTERNAL_INFRA_TASKS: an OpenAPI-provisioned operator carries one httpcalls
workflow step per endpoint group, so every turn opened with "45 steps" of
identical unnamed rows for a greeting; failing steps still show. And a
failed step now always renders detail -- "unknown" is the classifier's
shrug, not a diagnosis, so it is dropped in favour of the summary or a
pointer to the server log; real classifications (timeout, rate_limit) keep
their badge.
4. Operator answers rendered as literal ## and ** -- the one chat surface not
rendering markdown. Now the same contract as chat-message.tsx: remark-gfm,
formatMarkdownText repair, and deliberately NO rehypeRaw (operator output is
LLM output built from tool results, i.e. untrusted). User input stays
literal.
Plus: the operator input is now a textarea -- its own keydown handler already
special-cased Shift+Enter, on an element that cannot hold a second line. Same
Enter-sends / Shift+Enter-newline contract and auto-resize as chat-drawer, and
a shared InputHint ("Enter to send · Shift+Enter for a new line") under every
multi-line chat surface: operator, chat panel (hidden in secret mode, which is
a single-line password field), chat drawer. discussion-input already had its
own hints. Keys added to all 11 locales; the i18n drift and parity gates pass.
5148 tests pass, tsc -b clean.
…n budget Counterpart of the backend's maxToolIterations on setup-api. The engine default (10) killed real operator tasks mid-work: an agent build died at the cap after 22 calls, answering only "max tool iterations reached". OPERATOR_MAX_TOOL_ITERATIONS = 100 -- the backend ceiling (AgentSetupService.MAX_TOOL_ITERATIONS), on purpose: one operator turn is one admin task of arbitrary length, and the safety mechanism is the HITL gate on every write, not a scarce round budget. Ordinary agents keep the engine default. CreateApiAgentRequest (client type) documents the new optional field; the provisioning test pins that the operator actually sends 100.

… turns, reset coverage All three findings verified and correct. 1. The resting summary counted rawTasks while the list filtered httpcalls, so an operator greeting showed one visible row under a header still boasting "46 steps" -- the exact complaint the filter fixed, reintroduced one level up. The resting step count now follows the filtered list. Three metrics deliberately stay raw because they describe the TURN, not the list: the live progress fraction (a stable "3 of 5" over the whole pipeline; a visible-only denominator would crawl and jump as rows stream in), totalDuration (the turn really took that long), and the pulse (hidden steps running are still work in progress). CodeRabbit's suggestion covered all four; the partial application is reasoned, not an oversight. 2. The failed-turn error check only looked at token-streamed bubble content, but a turn can answer entirely through the done snapshot with zero token frames -- and an earlier recoverable task_failed would then overwrite a real answer with an error banner. The final output is now extracted from the snapshot for both branches: it backfills the empty bubble when present, and only its absence (with no stream, no pause, and a failed step) reports the failure. 3. resetOperator's endAllActiveConversations was implemented but untested; now covered, including that the undeploy precedes the delete -- the reset must not depend on the delete's cascade incidentally ending what the undeploy was refused for. One pre-existing test caught my first cut of (1) using the visible count in the live fraction too -- kept raw for the reason above; the test stands unchanged. 5154 tests pass, tsc -b clean.

All three findings verified and addressed in the latest push:
5154 tests pass, |
…geting probe, unknown no longer deletes The write canary was a coin flip: whether activation survived depended on an LLM choosing to perform a write on first ask. A cautious model that declined -- correct operator behaviour -- got the operator deleted. And the probe's one catastrophic path (gate broken, write executes) permanently renamed an arbitrary production agent, then deleted the only actor that could undo it. Three changes, composing with the backend's new gate-dry-run endpoint (labsai/EDDI 09fad6f44): 1. Deterministic check first. enforceWriteCanaryGate asks the backend to classify the canary's exact target call against the operator's STORED policy, via the same ToolApprovalGate.classify the tool loop runs at execution time. Not gated -> rollback WITHOUT running the probe: provoking a write against a policy known not to gate it would execute it for real, which is the destructive path entered knowingly. Dry-run transport errors fail closed as verification failures (never reported as a breach); a 404 means an older backend and restores the previous semantics wholesale. 2. unknown no longer deletes a verified operator. With the policy verified deterministically, a probe the model declined to perform proves nothing -- activation proceeds, returning the outcome honestly (what was verified, what stayed unproven) rather than upgrading it to a pass. 3. The probe targets the operator's OWN descriptor instead of "the FIRST agent from the list". The worst case is now self-cleaning: if the write ever executes, the marker lands on the agent the rollback deletes anyway -- no production agent touched, no manual marker-hunt. It also drops the listing round-trip, one less step for the model to stall on. The shared rollback tail moved into rollBack() (always throws, RollbackFailure marker) so the dry-run catch can re-throw its own rollback untouched. Tests rewritten for the new contract: verified+inconclusive proceeds without deletion; not-gated rolls back with the probe provably never started; old backend (404) keeps legacy rollback-on-unknown; dry-run 500 fails closed as a verification failure; prompt self-targets. Two prior tests that passed incidentally through an unhandled-request path now pin their intended scenarios explicitly. 5156 tests pass, tsc -b clean.
…where The operator chat gains the same attachment support as the main chat panel: a paperclip picker, staged chips with upload states, attachment-only turns, and attachment_* context refs on the sent turn. Attaching before the first message lazily creates the conversation the same way send() does. Both surfaces now also accept files from the clipboard — Ctrl/Cmd+V pastes a screenshot or copied file straight into the staging area; text pastes are untouched. Mechanics: the panel's proven staging logic (per-turn cap, StrictMode-safe object-URL lifecycle, conversation-switch reset) moves into a shared useAttachmentStaging hook, and the chip + bubble renderers become shared components — one implementation, both chats.
The main chat area and the operator chat are now drop zones: dragging files over them raises a dashed overlay, dropping stages them through the same shared staging as the picker and paste. Text-selection drags pass through untouched, secret mode and a paused operator ignore drops, and the enter/ leave depth counter keeps the overlay from flickering across child bubbles.
…onical answer
Two findings from the UX review pass:
The test-chat drawer is a full chat surface (same conversation, same send
path) but had no attachment support at all — it now shares the staging hook:
paperclip picker, chips, paste, drop zone over the drawer body, and
attachment-only turns.
With tool-loop streaming live, a turn can stream interim commentary ("Let me
check the agents...") before its final answer, but conversation memory keeps
only the final answer — so the bubble at rest disagreed with what a reload
would show. Both stores now snap the bubble to the done snapshot's canonical
text (and a paused turn rests on its pending message), instead of
back-filling only empty bubbles.
…he branch review Findings from the adversarial branch review, all verified before fixing: Object-URL lifecycle: the operator store now revokes sent-bubble previews on reset() and on the 409-refused-send path (every sent image used to leak its blob until page unload); a send refused by the store guards revokes the drained previews; the staging hook's conversation-switch reset best-effort DELETEs the uploaded blobs too instead of orphaning them server-side. ensureConversation dedupes concurrent creates behind one in-flight promise (two attach gestures used to create two conversations and silently orphan the first file), and a reset() during the create no longer resurrects the conversation. The staging hook also stops treating its own lazily-created id propagating back as a conversation switch - the chip that triggered the create survives. Canary: a stream that closes without a done frame is now unknown, not a teardown-triggering fail; the pause-but-unconfirmed message no longer claims detail knowledge when the approval-status read failed; task_failed frames count toward the attempted-write scan; the RollbackFailure re-throw guard is pinned by assertions on the not-gated path. A11y/i18n: drop overlay is aria-hidden, chip remove buttons carry the file name in their label, and the step-failed fallback is translated (11 locales).

…nown-outcome toast A disabled drop zone returned no handlers at all, so dropping a file onto a chat without a conversation (or in secret mode) let the browser NAVIGATE to the file, losing the app - disabled zones now swallow file drags inertly. The activation toast claimed "write access verified" for any truthy writeCanary result, including outcome "unknown" (gate verified deterministically, live probe inconclusive) - it now says exactly which of the two happened, keyed on outcome === "pass" (new locale key, 11 locales). The no-done-frame canary unknown now records whether the write attempt was observed (a gated pause and an executed write both leave the same trace entry, so the attempt alone can never justify "fail"), and the step-count test matchers are digit-anchored so "1 steps" can no longer match "41 steps".

Fixes found by using the Platform Operator end to end against a live deployment. Five commits, each self-contained; together they take the operator from "fails opaquely at every stage" to usable.
1. The write canary deleted healthy operators (
cc6b27fa)Activating with write scope failed reproducibly:
The operator was fine — server logs showed it listing agents and answering normally;
patchDescriptorwas among its 47 tools (23 read + 24 write, the exact discovered count). Asked to pick "any ONE" agent and rename it with no stated reason, it asked which one — correct behaviour for an agent whose own system prompt hardens it against loosely-specified instructions. The probe read caution as failure and the rollback deleted it.unknownandfailno longer report identically. Both still roll back (write tools behind an unverified gate must not stay deployed), but unknown now says "this is not evidence the gate is broken" and offers retry / read-only, while fail says the gate did NOT hold and explicitly does not suggest retrying.Still probabilistic by construction — an LLM chooses the tool. The deterministic fix (classifying a synthetic request through the backend gate, no model, no write) is tracked separately.
2. Teardown showed 409/404 on success (
9cde2946)Deactivating the operator 409'd because the backend refuses to undeploy an agent with active conversations — and the admin's own operator chat is one. Using the operator at all made the kill switch fail, with the TEXT_PLAIN explanation discarded. Both
deactivateOperatorandresetOperatornow passendAllActiveConversations=true: the conversations ended are this operator's own, and the admin is explicitly shutting it down.3. Failures were invisible or misleading (
9cde2946)task_failed, streams nothing, closes normally) left an empty bubble and no explanation — observed live when a provider rejected the stored LLM config. The done handler now surfaces the failing step and its redacted summary as the chat error; recovered turns and pauses stay quiet.httpcallsjoins the internal-step filter: an OpenAPI-provisioned operator carries one workflow step per endpoint group, so every turn opened with "45 steps" of identical unnamed rows for a greeting. Failing steps still show.UNKNOWNbadge is gone — it's the classifier's shrug, not a diagnosis. Failed steps now always show the summary or a pointer to the server log; real classifications (timeout,rate_limit) keep their badge.4. Markdown + multi-line input (
9cde2946)##and**. Now the same contract aschat-message.tsx: remark-gfm,formatMarkdownText, deliberately norehypeRaw(operator output is LLM output built from tool results — untrusted). User input stays literal.<input>whose own keydown handler special-cased Shift+Enter — on an element that cannot hold a second line. Now a self-resizing textarea, with a shared hint ("Enter to send · Shift+Enter for a new line") under every multi-line chat surface, translated in all 11 locales (drift + parity gates pass).5. 100-round tool budget (
5db0c897)An agent-build task died at the engine's 10-iteration default after 22 calls, answering only "max tool iterations reached". The operator now provisions with
maxToolIterations: 100— the backend ceiling, on purpose: one operator turn is one admin task of arbitrary length, and the safety mechanism is the HITL gate on every write, not a scarce round budget. Ordinary agents keep the default.2d8c26f6a(labsai/EDDI#672) — earlier backends ignore the unknown field harmlessly, so this degrades gracefully, but the budget only takes effect against a backend that accepts it. Existing operators keep their stored budget until re-activated.Verification
