From 0648f2488afd400de6b0a7261431fc367ecde10e Mon Sep 17 00:00:00 2001 From: Anderson Leal Date: Tue, 7 Jul 2026 20:41:15 -0300 Subject: [PATCH 01/28] feat(harness): queue messages and notifications during streaming (MOT-3837) Messages and subagent notifications arriving while a turn streams now land in a durable per-session queue (harness_queue state scope) instead of being appended mid-stream or racing the in-flight generation. The loop drains the queue at the start of the next step, in arrival order, under the deterministic entry ids the rows were queued with, so redelivery is idempotent. - harness::send / harness::inject enqueue instead of appending while a turn is Running; parked (awaiting_functions) turns still append immediately. - Steering now treats any non-Custom queued row like a trailing user message, closing a gap where a custom-role message merged into a running turn could be silently dropped if the final step made no function calls. - finalize_* drains best-effort on completion/failure/cancellation so a message that arrives as the turn dies is never stranded. - harness::status now reports the session's queued rows. --- harness/src/functions/send.rs | 113 ++++- harness/src/functions/status.rs | 7 + harness/src/ids.rs | 13 + harness/src/state.rs | 127 ++++- harness/src/turn_loop.rs | 60 ++- .../tests/golden/schemas/harness.send.json | 7 + .../tests/golden/schemas/harness.status.json | 463 ++++++++++++++++++ tech-specs/2026-06-agentic/harness.md | 62 ++- 8 files changed, 808 insertions(+), 44 deletions(-) diff --git a/harness/src/functions/send.rs b/harness/src/functions/send.rs index dbc59ad05..e9e73bf2e 100644 --- a/harness/src/functions/send.rs +++ b/harness/src/functions/send.rs @@ -91,6 +91,10 @@ pub struct SendResponse { /// True when folded into an in-flight turn (steering). #[serde(default, skip_serializing_if = "Option::is_none")] pub merged: Option, + /// True when the message was queued while a step was streaming; it lands + /// in the transcript when the stream ends. + #[serde(default, skip_serializing_if = "Option::is_none")] + pub queued: Option, /// True when `idempotency_key` matched an earlier send. #[serde(default, skip_serializing_if = "Option::is_none")] pub deduplicated: Option, @@ -101,6 +105,7 @@ pub struct StartOutcome { pub session_id: String, pub turn_id: String, pub merged: bool, + pub queued: bool, pub deduplicated: bool, } @@ -111,6 +116,7 @@ pub async fn handle(deps: &Deps, req: SendRequest) -> Result Result Result session.create(title.as_deref(), metadata.as_ref()).await?, }; - // Persist the user message (idempotent entry id when a dedupe key is set). + // Entry id: idempotent when a dedupe key is set. let entry_id = req .idempotency_key .as_ref() .map(|k| ids::idem_user_entry_id(k)); - let appended_entry = session - .append(&session_id, &message, entry_id.as_deref(), None, None) - .await?; - // CAS-seed the turn (or take the merge path). - let outcome = seed_or_merge(deps, &cfg, &session_id, options).await?; + // Queue path: a `Running` step may be streaming — park the message as a + // durable queue row the loop drains after the stream ends, instead of + // appending mid-transcript. + let (outcome, entry) = match try_enqueue( + deps, + &cfg, + &session_id, + &message, + entry_id.as_deref(), + None, + &options, + ) + .await? + { + Some((outcome, row_entry)) => (outcome, row_entry), + None => { + // Append path (no turn / terminal / parked): persist the message, + // then CAS-seed the turn (or take the merge path). + let appended_entry = session + .append(&session_id, &message, entry_id.as_deref(), None, None) + .await?; + let outcome = seed_or_merge(deps, &cfg, &session_id, options).await?; + (outcome, appended_entry) + } + }; // Record the idempotency mapping (TTL-bound by contract). if let Some(key) = &req.idempotency_key { let rec = IdemRecord { session_id: session_id.clone(), turn_id: outcome.turn_id.clone(), - entry_id: appended_entry, + entry_id: entry, ts: AgentMessage::now_ms(), }; let _ = crate::state::put_idem(&deps.iii, key, &rec, cfg.session_timeout_ms).await; @@ -218,12 +245,82 @@ pub async fn inject( )) })?; + if let Some((outcome, _)) = + try_enqueue(deps, &cfg, session_id, &message, entry_id, origin, &options).await? + { + return Ok(outcome); + } session .append(session_id, &message, entry_id, None, origin) .await?; seed_or_merge(deps, &cfg, session_id, options).await } +/// The queue path: while a turn step is `Running` a stream may be in flight, +/// so the message parks as a durable `harness_queue` row the loop drains after +/// the stream ends (harness.md § Concurrency & steering).

That fallback (`join_delivery_session`) was only ever invoked from the join-satisfaction path, though: a plain, single-predecessor reaction (no join) with no `session_id` pin dispatched the raw, unresolved spec, so `harness::spawn` minted a fresh anonymous session instead. Reproduced live: a pipeline stage registered a turn-completed reaction with no session_id, explicitly intending its result to land back in the registering session — instead it was stranded in an orphaned `s_...` session nobody was watching. Resolve the owner fallback once, before the join/non-join split, so both dispatch paths share it.

Three guards: 1. Agent prompts (harness default/cli + all six provider identities): a denied required function means the task FAILED — report it as the first line, never bury it under deliverable-looking output. 2. Same prompts: children run fail-closed from a read-mostly baseline — grant whatever the task requires via options.functions.allow; plus a final-checklist item to verify every armed reaction has a producer that can actually produce the watched key/event. 3. Console triggers strip: state bindings now show their watched key and whether it exists ("on wiki-pipeline/summary — not written yet"), probed via state::get while the strip is expanded, so a pipeline armed on an unwritable key is diagnosable at a glance. --- console/web/src/components/chat/ChatView.tsx | 15 ++--- .../components/chat/SessionTriggers.test.ts | 25 +++++++- .../src/components/chat/SessionTriggers.tsx | 57 ++++++++++++++++++- console/web/src/lib/backend/real.ts | 18 ++++++ console/web/src/lib/backend/types.ts | 10 ++++ harness/prompts/cli.txt | 18 ++++++ harness/prompts/default.txt | 18 ++++++ provider-anthropic/prompts/identity.txt | 4 ++ provider-llamacpp/prompts/identity.txt | 4 ++ provider-openai-codex/prompts/identity.txt | 15 +++++ provider-openai/prompts/identity.txt | 15 +++++ provider-xai/prompts/identity.txt | 15 +++++ provider-zai/prompts/identity.txt | 4 ++ 13 files changed, 207 insertions(+), 11 deletions(-) diff --git a/console/web/src/components/chat/ChatView.tsx b/console/web/src/components/chat/ChatView.tsx index 710a54e49..9fd534a23 100644 --- a/console/web/src/components/chat/ChatView.tsx +++ b/console/web/src/components/chat/ChatView.tsx @@ -20,10 +20,7 @@ import { useWorktreeEvents } from '@/hooks/use-worktree-events' import type { ChatBackend } from '@/lib/backend' import { predictedUserEntryId } from '@/lib/backend/harness-send' import type { SessionTriggerInfo } from '@/lib/backend/triggers' -import type { - CompactResult, - QueuedMessagePreview, -} from '@/lib/backend/types' +import type { CompactResult, QueuedMessagePreview } from '@/lib/backend/types' import { useConversationsCtxOptional } from '@/lib/conversations-context' import { expandFileMentions, parseFileMentions } from '@/lib/file-mentions' import { formatStopReason } from '@/lib/format-stop-reason' @@ -58,10 +55,10 @@ import { type UserMessage, } from '@/types/chat' import { Composer, type ComposerSubmitPayload } from './Composer' -import { SessionTriggers } from './SessionTriggers' import { ContextUsage } from './ContextUsage' import { ExportSessionButton } from './ExportSessionButton' import { MessageList } from './MessageList' +import { SessionTriggers } from './SessionTriggers' import { WorktreeBadge } from './WorktreeBadge' function isAbortError(err: unknown): boolean { @@ -291,7 +288,8 @@ export function ChatView({ const last = [...conversation.messages] .reverse() .find( - (m): m is AssistantMessage => m.role === 'assistant' && Boolean(m.model), + (m): m is AssistantMessage => + m.role === 'assistant' && Boolean(m.model), ) if (!last?.model) return null const catalog = modelOptions.find( @@ -601,9 +599,7 @@ export function ChatView({ }, ) } catch (err) { - setQueuedDrafts((drafts) => - drafts.filter((d) => d.id !== userMsg.id), - ) + setQueuedDrafts((drafts) => drafts.filter((d) => d.id !== userMsg.id)) onAppendMessage( conversationId, makeSystemNotice( @@ -1167,6 +1163,7 @@ export function ChatView({ {queuedStrip.length > 0 ?

One `harness::turn-completed` subscription per predecessor, `config { session_id: "" }` — NOT `parent_session_id` (matches EVERY child; the first completion fills every join key). Every predecessor's `metadata` = the SAME full downstream spec (combiner `model` + `task` on all), only `key` differs: `{ model, task, join: { id: "J", expect: ["a","b","c"], key: "a" } }`. `expect` = ARRAY of all predecessor keys (never a count), including this one's own `key`. Missing `model`/`task` → metadata silently ignored, join never fires; differing tasks → nondeterministic (last arrival's spec spawns). THEN spawn the predecessors into those ids. `harness::react` accumulates results durably and spawns the downstream exactly once when the last arrives, fed all of them (a failed predecessor counts as arrived), then auto-unregisters the join's predecessor subscriptions — `join.rearm: true` on every predecessor keeps them registered, refiring on each next complete set (standing watchers). A completed join's downstream spawns into the registering session — leaving `metadata.session_id` OUT of the predecessors' spec is what lands the pipeline's final output back in THIS chat as a new turn; pinning ANY `session_id` there (e.g. an invented "reporter-final") re-aims delivery INTO that other session and this chat sees nothing — pin only to deliver elsewhere on purpose.

Subject: [PATCH 14/28] feat(console): clamp, label, and copy affordances for
 function-call panes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The request/response panes rendered payloads unbounded — a schema-sized
response dumped hundreds of lines into the chat flow — with no way to
copy them. Every pane now shares one PaneShell:

- bodies past 24 rendered lines clamp to ~16 code lines behind an
  explicit '▾ show all · N lines' footer (collapse to close), so large
  payloads stop drowning the conversation
- a copy button in the label row (copies the canonical payload — the
  full envelope for unwrapped responses, the parsed body otherwise)
- header hints (single key, json string) unified into one hint system

Same schematic chrome throughout: paper-2 label rows, hairline rules,
mono caps, no radius, no motion.

ChatView fires every unregister via Promise.allSettled, tolerates partial failure, and surfaces a single notice. No modal — the confirm lives in the strip. - flow: a 'flow' button opens a dialog rendering the whole reactive pipeline as a layered node-link DAG — state keys and watched sessions on the left, the sub-agents they spawn flowing right, joins as fan-in gates. Same surface pattern as WorktreeGraph (absolute HTML nodes over one SVG of orthogonal elbow edges). State roots are colored by whether their key was written yet, so a stalled pipeline is visible at a glance; a legend reads the node/edge vocabulary. - the pure trigger introspection + workflow logic moved to a new trigger-graph.ts (no React), with the new buildTriggerDag/layoutTriggerDag graph builder. SessionTriggers re-exports the three symbols its existing test imports, so that test is untouched.

Add that primitive and the composer ergonomics: - harness::unqueue (trusted, off the agent catalog): removes a still- parked queued row by its client-visible entry_id (resolved to the internal row id for deletion). Best-effort — an already-drained row is removed:false. - backend.removeQueued → harness::unqueue. - LexicalShell: Up-arrow in an EMPTY editor recalls a message for editing (gated on empty so an in-progress draft is never clobbered; defers to an open typeahead). Loads the returned text, caret at end. - ChatView: recall the most recent queued draft — drop the local draft, remove the server row (surfacing a warn notice if removal fails, since the strip also re-shows it), hand text + attachments to the composer. Only wired when the backend can remove queued rows (recall without removal would double-deliver). A '↑ to edit' hint sits under the strip. Attachments are display-only (content rides the text's #file mentions), so recalling them is safe.

Update it in place instead. - harness::edit_queued (trusted, off-catalog): find the row by entry_id and rewrite its message, keeping the same internal id — so re-writing the same session_id:id state key overwrites in place, preserving queued_at (position), entry_id, and origin. Emits harness::message-queued so other tabs refetch the new content. - backend.editQueued rebuilds the message exactly as a send does (string sugar, or structured with #file() expansions) via an extracted buildMessageInput. - Composer: submitting a browsed message now saves it in place (onEditQueued) rather than sending a new one; submitting an emptied composer removes it (onEditQueued(id, null) → harness::unqueue). ChatView updates the draft optimistically and re-expands mentions for the server write. - Strip hint: 'enter saves in place · empty + enter removes'. The prior remove-then-resend path (and the tail reorder it caused) is gone; browsing an unedited message and hitting enter is now a no-op move. --- console/web/src/components/chat/ChatView.tsx | 98 +++++++++++++++----- console/web/src/components/chat/Composer.tsx | 32 ++++--- console/web/src/lib/backend/real.ts | 55 ++++++++--- console/web/src/lib/backend/types.ts | 12 +++ harness/src/functions/mod.rs | 11 +++ harness/src/functions/send.rs | 67 +++++++++++++ 6 files changed, 223 insertions(+), 52 deletions(-) diff --git a/console/web/src/components/chat/ChatView.tsx b/console/web/src/components/chat/ChatView.tsx index 0f156d2db..1dbdfc7ea 100644 --- a/console/web/src/components/chat/ChatView.tsx +++ b/console/web/src/components/chat/ChatView.tsx @@ -42,6 +42,7 @@ import { } from '@/lib/worktrees' import { type AssistantMessage, + type Attachment, type Conversation, DEFAULT_THINKING_LEVEL, type FunctionCallMessage, @@ -329,25 +330,76 @@ export function ChatView({ [queuedDrafts], ) - // Commit an edit: drop the browsed message from the queue (local draft + - // server row) so the resubmitted text replaces it rather than duplicating. - // Best-effort removal — a row that already drained is a no-op; a failure - // means the old version may still deliver, so surface it.
