Replace the six inline queryAll calls in routes-agents-standup.ts with
typed domain methods: db.agents gains listDirectReportsForStandup and
listReportStatusesForStandup (LEFT JOIN aggregation), db.tasks gains
listAssigneeTasksForStandup and listTasksForAssignees (safe on empty
assignee list), db.approvals gains listAgentPendingApprovals and
listAgentResolvedApprovals. Shared listRecentTaskComments is reused.
Replace the ad-hoc getApproval helper and the filterable list query
in routes-approvals.ts with db.approvals methods. Add findApprovalById
(non-throwing lookup returning null) and listApprovalsForApi (accepts
requestedByAgentId / relatedTaskId / statuses filters and builds the
prepared statement inside the domain layer).
Replace six inline queryAll calls in routes-work-graph.ts with domain
methods. db.entityCrud gains listGoals, getGoalForUpdate, listProjects,
getProjectForUpdate. db.knowledge gains listSprints. db.company gains
getDashboardSnapshot, which returns the raw agent/task/activity rows
the dashboard handler aggregates. The route-level row shapes are
preserved in the new GoalListRow / ProjectListRow / SprintListRow
types so HTTP responses remain identical.
Replace inline queryAll calls in routes-tasks.ts with two new domain
methods: tasks.listTasksByStatuses (used by GET /api/companies/:id/issues)
and documents.listImportantDocsForReview (used by the deliverable-review
gate). Routes now hold no SQL or column-mapping logic; the
TaskListByStatusesRow shape preserves the existing HTTP response fields
including requiresUserReview as a boolean.
Replace the racy three-step heartbeat path (listAgentTasks ->
findReusableHeartbeatTask -> saveTask -> checkoutTask) with a single
transactional acquireHeartbeatTask method. The prior flow allowed two
concurrent scheduler ticks to both observe "no reusable heartbeat" and
both INSERT a fresh [Heartbeat] task before either CAS-checked out,
producing duplicates that cleanupDuplicateHeartbeatTasks had to mop up.
acquireHeartbeatTask runs inside BEGIN IMMEDIATE so concurrent ticks
serialize on the writer lock. Inside the transaction it first attempts
to claim any existing claimable [Heartbeat] task (todo/backlog/done/
in_review with checkout_run_id IS NULL), reviving done/in_review by
resetting status. If nothing is claimable but an in-flight heartbeat
exists (status NOT IN done/cancelled), it returns null instead of
creating a duplicate. Only when no heartbeat task exists at all does it
INSERT a new one, already in 'in_progress' with checkout_run_id set.
cleanupDuplicateHeartbeatTasks remains as deletion-side defense.
Applies WAL journal, 5s busy_timeout, synchronous=NORMAL, and
foreign_keys=ON pragmas immediately after opening each connection so
concurrent main+worker writers share the same locking configuration
and avoid SQLITE_BUSY under contention.
