Bohan Jiang	69744241e8	fix(comment): restore autopilot @mention delegation authority (MUL-4857) (#5512) ... * fix(comment): restore autopilot @mention delegation authority (MUL-4857) A schedule/webhook autopilot run is unattributed by design (no top-of-chain human originator, MUL-4302). Since MUL-3963 the A2A invoke gate (canInvokeAgent) keys on that originator, so a mid-run @agent/@squad delegation on an autopilot-created issue fails closed for the DEFAULT private agent (and member-scoped public_to agents): the mention renders but no run is enqueued. The SAME autopilot's first dispatch is admitted via the autopilot creator (autopilotAdmitInvoke -> canCreatorInvokeAgent), so first-dispatch and mid-run delegation disagreed. Align them: when an unattributed agent/system-authored comment on an autopilot-origin issue reaches computeCommentAgentTriggers with no originator, fall back to the autopilot creator as the effective invoking user for the gate. The gate still runs (no unrestricted agent-to-agent bypass); it is authorization only -- the enqueued task's originator/attribution stays unattributed. Scoped to autopilot-origin issues so other unattributed chains stay fail-closed. Adds a DB-backed regression test covering: creator-owns-target admits, a non-autopilot unattributed run stays denied, and a creator without invoke rights stays denied. Co-authored-by: multica-agent <github@multica.ai> * fix(comment): bind autopilot @mention authority to verified task lineage (MUL-4857) Address the review's confused-deputy finding on the P0 fix. The first cut keyed the invoke-gate fallback on issue provenance + an empty originator alone (invokeAuthorityForAutopilotIssue took only the issue), so any unattributed run could borrow a stranger autopilot creator's rights merely by commenting on that autopilot's issue — and the fallback also leaked past explicit @mention into the plain-comment squad-leader path and system actors. Rework it so the autopilot-creator authority is granted ONLY when the SPEAKING task's lineage is verified against this issue: - resolve the authority separately (new AutopilotDelegationAuthorityUserID on commentTriggerComputeOptions), never by overwriting OriginatorUserID; the gate reads it through opts.effectiveInvoker() only when no human originator resolved, so attribution stays untouched; - resolve from a server-trusted speaking task — X-Task-ID on create/preview, comment.source_task_id on edit/reconcile — via autopilotDelegationAuthority, which admits only when author == task agent AND task.issue_id == this issue AND the issue is autopilot-origin, then keys on the member autopilot creator; - do NOT key on autopilot_run_id: in create_issue mode (the reported case) the leader task is enqueued through the ordinary issue-assignment path and has no autopilot_run_id — the task.issue_id == issue binding is what proves the run is part of this autopilot's work while rejecting foreign-issue runs. Tests: replace the provenance-only regression with lineage-bound coverage — verified-lineage-admits, creator-without-rights-denied, non-autopilot-denied, missing-source-task-denied, cross-issue-source-task-denied, author!=task-agent- denied — plus an end-to-end CreateComment path asserting the private worker is enqueued and the delegated run stays unattributed. Verified the fallback is load-bearing (positive + e2e fail with it disabled) and the full internal/handler package passes. Skill docs (multica-mentioning) updated to the lineage-bound contract and new helper names. Co-authored-by: multica-agent <github@multica.ai> * fix(comment): make autopilot @mention authority consistent across defer/edit (MUL-4857) Second review round (Elon) surfaced two must-fixes on top of the lineage binding. 1. Busy-target completion reconcile lost the authority. A delegation to a target that is already running is deferred to that target's completion reconcile (reconcileCommentsOnCompletion). That path recomputed triggers with only the (empty) originator, so an unattributed autopilot delegation's follow-up was gate-denied again and silently dropped. It now restores the delegation authority from comment.source_task_id, so the follow-up fires once the target frees up — still unattributed. 2. Edit could borrow the old authoring run's authority, and preview != save. The edit preview keyed authority on the current request task while save keyed it on the comment's original source_task_id, so an agent editing its old autopilot comment from a task on an UNRELATED issue would fail-closed in preview but reuse the old autopilot creator's authority on save (cross-issue confused-deputy, and a preview/side-effect divergence). Fix: treat source_task_id as the persisted per-action authority lineage and re-stamp it on edit to the CURRENT editing task, issue-scoped exactly like CreateComment. A cross-issue edit re-stamps it to NULL, so preview, save, AND the deferred reconcile all fail closed identically. UpdateComment query gains a source_task_id param (sqlc regen). Also locks the review-accepted behavior that effectiveInvoker() carries the autopilot-creator authority into the plain assigned-squad-leader wake (a worker's result comment on the autopilot issue can still wake the private leader). Tests: reconcile-restores-authority (owns -> one unattributed follow-up; no rights -> none); edit re-stamp (same-issue keeps authority and triggers; cross-issue clears source_task_id and fails closed); worker-result wakes private squad leader. Verified both fixes are load-bearing (each negative control reproduces the exact regression Elon described), full internal/handler + internal/service packages pass, gofmt/vet clean. Skill docs (multica-mentioning) updated. Co-authored-by: multica-agent <github@multica.ai> * fix(comment): clear stale task lineage on non-author comment edits (MUL-4857) An admin editing an autopilot Agent's comment previously preserved the comment's original source_task_id. The immediate save is judged on the admin's member identity and correctly fails closed, but the deferred completion-reconcile routes the comment under its original agent author and resolved the delegation authority from the stale source_task_id, resurrecting the autopilot creator's invoke authority once the busy target freed up — an admin (manage rights) could thereby trigger another owner's private agent (invoke rights). Now a content edit re-derives lineage from the edit action: only the agent author editing its own comment re-stamps source_task_id to the current editing task; every other editor (member/admin, or any non-author) clears it, so preview, save, and reconcile all fail closed. Adds a regression covering the admin-edit + busy-target path and syncs the multica-mentioning skill docs.

Multica Eve	bf161f2f9c	fix(tasks): preserve merged comment delivery (#5192) ... Track actual claim-time delivery, support legacy daemons, and repair comment batches across claim, retry, edit, and delete races. MUL-4348 Co-authored-by: Eve <eve@multica-ai.local> Co-authored-by: multica-agent <github@multica.ai>	2026-07-10 14:10:10 +08:00
Multica Eve	4db1abe11d	fix(comment): compensate dropped agent→agent @mentions in completion reconcile (MUL-4304) (#5148) ... * fix(comment): compensate dropped agent→agent @mentions in completion reconcile (MUL-4304) When agent A explicitly @mentions agent B while B already has a dispatched/running task, the create-time enqueue path can only fold the comment into a QUEUED task; on a merge miss it defers to completion reconcile. But reconcileCommentsOnCompletion listed only member comments (ListMemberCommentsForIssueSince, author_type='member'), so A's agent-authored mention was never replayed and B was silently never woken — the intermittent 'agent @ agent fails to trigger' bug. Broaden the reconcile query to member+agent comments and route each under its own author_type. For an agent author, computeCommentAgentTriggers only produces triggers for explicit @agent/@squad mentions (plus the narrow assigned-squad-leader fallback), and reconcile still keeps only triggers routing to the agent that just ran — so plain agent replies never qualify and no unrelated agent is re-woken. Agent originator is resolved from the comment's source task so canInvokeAgent authorizes A2A correctly. Adds two covering tests: an agent-authored @B mention earns exactly one B follow-up; a plain agent reply (no mention) earns none. Co-authored-by: multica-agent <github@multica.ai> * fix(comment): address MUL-4304 review — exercise real dispatched drop + explicit-mention-only reconcile Review must-fix 1: the regression test used a 'running' task, which does not reproduce the drop (running-only is not AlreadyPending, so it takes the normal fresh-enqueue path). Rewrite it to drive the ACTUAL failure: B has a DISPATCHED task, agent A's explicit @B mention goes through the real trigger path (triggerTasksForComment), assert it is dropped at creation (0 queued follow-up), then complete B's task and assert reconcile recovers exactly 1 follow-up. Correct the 'dispatched/running' wording in daemon.go and comment.sql to 'dispatched'. Review must-fix 2: agent-authored comments on a squad-assigned issue can route to the squad leader via routeAssignedSquadLeaderFallback (a non-mention route), so 'plain reply yields nothing' was not unconditionally true. Scope reconcile's agent-comment compensation to EXPLICIT @agent/@squad mentions only (keepExplicitMentionTriggers, Source in {mention_agent, mention_squad_leader}); the squad-leader/assignee fallback and all other conversational routing are intentionally not replayed. Add a squad-assigned plain-worker-reply test proving the leader gets no completion-driven follow-up (verified failing without the filter). Update doc comments accordingly.

Multica Eve	75695a2e40	fix(comments): guarantee at-least-once processing of user comments (MUL-4195) (#5068) ... * fix(comments): guarantee at-least-once processing of user comments (MUL-4195) Consecutive comments on an issue were silently dropped: a new comment that arrived while the agent already had a queued/dispatched task was discarded by the HasPendingTaskForIssueAndAgent dedup, losing the user's follow-up instruction with no visible trace. Comments — unlike chat — are deliberate, addressed, persisted input and must never vanish. This makes comment handling at-least-once while keeping concurrency bounded to one run per (issue, agent): - Merge, don't drop (PR1): a comment landing while a not-yet-started task exists is folded into that task — the prior trigger becomes a coalesced comment and the new one becomes the trigger, so a single run still covers every deliberate comment. Falls back to a fresh enqueue if the pending task was claimed mid-flight, so nothing is lost in the race. - Completion reconciliation (PR2): on task completion, a member comment newer than the run's started_at schedules exactly one follow-up via the normal trigger pipeline. Loop-safe: member-authored only, capped by the existing per-(issue,agent) dedup, and terminating. - Visibility (PR3): coalesced_comment_ids is surfaced on the task API and in the run prompt so the covered comments are explicit. Migration 145 adds agent_task_queue.coalesced_comment_ids UUID[]. Tests: merge-not-drop preserves all three of a rapid burst and repoints the trigger to the newest; reconciliation query gates on member/since; e2e CompleteTask enqueues a follow-up for a mid-run member comment and does not for none. Co-authored-by: multica-agent <github@multica.ai> * fix(comments): address review — originator gate, agent-scoped reconcile, cross-thread coalesced prompt (MUL-4195) Resolves GPT-Boy's Request-changes review on PR #5068. Must-fix #1 — merge no longer inherits a stale originator/runtime context. MergeCommentIntoPendingTask now only folds a comment into a pending task whose originator_user_id IS NOT DISTINCT FROM the new comment's originator. runtime_mcp_overlay / runtime_connected_apps are a pure function of (originator, agent) and the agent is fixed, so a matching originator keeps the stored overlay/attribution valid; a differing originator (e.g. user B commenting on a task originated by user A) matches no row and the caller enqueues a fresh follow-up with B's own context instead of reusing A's. trigger_summary is refreshed to the new trigger comment. Must-fix #2 — completion reconcile no longer re-wakes unrelated agents. reconcileCommentsOnCompletion computes the latest member comment's triggers and keeps ONLY the agent that just completed, instead of fanning the comment out through the full pipeline. An @-mention of agent B during agent A's run is triggered once at creation time and is no longer replayed (double-run) when A completes. Should-fix #3 — coalesced-comment prompt no longer assumes a single thread. The claim response now carries each folded comment's thread id / author / created_at / content (CoalescedCommentData); the prompt embeds them directly so the agent addresses cross-thread folded comments without the wrong "they are in the triggering thread" hint. Old servers that ship only ids fall back to an issue-wide fetch, still without the same-thread assumption. Tests: TestMergeCommentIntoPendingTask_OriginatorGate (query gate), TestCompleteTask_DoesNotReTriggerOtherAgentMentionedDuringRun (reconcile scoping), TestBuildCommentPromptCoalescedCrossThread / IDsOnlyFallback (prompt). Existing MUL-4195 suites still pass. Co-authored-by: multica-agent <github@multica.ai> * fix(comments): close unique-index drop + dispatched-window race in comment coalescing (MUL-4195) Second-round review follow-up on PR #5068. Must-fix #1 — originator-mismatch no longer drops the comment. The previous originator gate returned ErrNoRows on a different originator and the caller fell through to a fresh enqueue, which collided with the idx_one_pending_task_per_issue_agent unique index (one queued/dispatched task per (issue, agent)) — silently dropping the second user's comment. Replaced the gate with recompute-on-merge: MergeCommentIntoPendingTask now re-stamps originator_user_id, runtime_mcp_overlay, runtime_connected_apps and trigger_summary to the new comment's originator. A different member's comment folds into the single coalescing run carrying the latest instruction's own identity/overlay (no cross-user capability bleed, no drop, no collision). Must-fix #2 — comment arriving in the claim→StartTask window is no longer lost. Merge now targets only PRE-CLAIM states ('queued','deferred'); a dispatched/running task is never a merge target, so a post-claim comment is never falsely stamped into coalesced_comment_ids as "delivered". Completion reconcile is re-anchored on dispatched_at (the moment the claim response is built) instead of started_at, and sweeps ALL undelivered member comments since that anchor — replaying each through the normal enqueue path so they coalesce into one bounded, agent-scoped follow-up run. This covers the dispatch→start window a started_at anchor missed. Enqueue path: on a merge miss the caller no longer blindly fresh-enqueues (which could collide with a dispatched sibling); it defers to the active task's completion reconcile via HasActiveTaskForIssueAndAgent, and only fresh-enqueues when no active task exists. Tests: rewrote the query test to TestMergeCommentIntoPendingTask_RecomputesOriginatorAndSkipsDispatched; added TestConsecutiveCommentsDifferentOriginatorsFullEnqueuePath (full handler enqueue path, two distinct originators) and TestCompleteTask_ReconcilesDispatchedWindowComment (claim→start window). All existing MUL-4195 handler/cmd-server/daemon/service suites still pass. Co-authored-by: multica-agent <github@multica.ai> * fix(comments): catch pre-dispatch merge-race comment in completion reconcile (MUL-4195) Third-round review follow-up on PR #5068. Race: a member comment is created while the task is still queued, but its merge loses the race to the daemon claiming the task (queued→dispatched). The merge then finds no pre-claim row (ErrNoRows), the enqueue path defers to reconcile — but the comment's created_at is BEFORE dispatched_at, so the dispatched_at-anchored reconcile skipped it and the comment vanished with no task coverage. Fix: anchor completion reconcile on the task's created_at (which always precedes dispatch) instead of a dispatch/start timestamp, and exclude the run's DELIVERED SET — trigger_comment_id ∪ coalesced_comment_ids. Because merges only ever touch pre-claim rows, that set is exactly what the claim response carried, so any member comment created since the task was made that is NOT in it was genuinely undelivered and earns a bounded follow-up. This catches the pre-dispatch merge-race comment and the dispatch→start comment, while never re-firing a comment that was delivered as a pre-claim coalesced entry. Test: TestCompleteTask_ReconcilesPreDispatchMergeRaceComment reproduces the race (comment created pre-dispatch, task dispatched before merge, plus a delivered coalesced comment) and asserts exactly one follow-up, triggered by the race comment, with the delivered coalesced comment excluded. Existing reconcile fixtures updated to set a realistic created_at (the production invariant that created_at is the earliest task timestamp). Co-authored-by: multica-agent <github@multica.ai> * fix(comments): merge only into the queued task, never a deferred fallback (MUL-4195) Fourth-round review follow-up on PR #5068. MergeCommentIntoPendingTask targeted status IN ('queued','deferred') ordered by created_at DESC. When a (issue, agent) pair had both an older queued task (the run about to be claimed) and a newer deferred assignee-fallback task, a new comment merged into the deferred row instead of the queued one — so the comment missed the imminent run and the deferred fallback could later promote into a duplicate/conflicting run. This merge is only ever reached when HasPendingTaskForIssueAndAgent matched a queued/dispatched task (it never inspects deferred), so the coalescing target must be the queued row. Restricted the merge target to status = 'queued' (the unique index guarantees at most one). Deferred fallbacks keep their own fire_at/promotion escalation lifecycle and are never a merge target. Test: TestMergeCommentIntoPendingTask_TargetsQueuedNotDeferred seeds an older queued task + a newer deferred fallback for the same (issue, agent), merges a new comment, and asserts it lands on the queued task (trigger repointed, old trigger coalesced) while the deferred fallback is left untouched.
