feat(polish): cost caps + DAG + tiers + preflight + checks panel

- Cost caps: budget_caps table, MTD spend ledger, tRPC budgets router, orchestrator pause on cap
- DAG viz: convoy-dag.tsx SVG for brief dependencies in Mission Control
- Automation tiers: manual|assist|auto per convoy, orchestrator respects manual
- Preflight: connected-repos preflight endpoint
- Checks panel: forge checks stub in detail panel
- Budget caps schema + tRPC router + Settings UI stub

+# Polish — DAG + tiers + cost caps + preflight + checks (closing follow-ons)
+
+## Why
+
+Second-brain v0.1 + worker-closeout + owner-cockpit left `draft` follow-ons that block a clean `Plan-automation-foundation` `done`: `Task-cost-budget-ui-and-caps` Epic 1, `Task-repo-setup-preflight` Epic 3, `Task-pr-checks-recovery-panel` Epic 8, `Task-convoy-dag-visualization` + `Task-automation-tiers` Epic 5. This convoy closes them with `role-doc-writer` for SOPs.
+
+Per `plans/Plan-automation-foundation/Plan-automation-foundation.md:332` Polish section and `docs/decisions/2026-08-25-second-brain-os-pivot.md`.
+
+## Scope
+
+1. **Cost budget caps** `Task-cost-budget-ui-and-caps` — month-to-date spend per `model_providers.metadata.tier`, `Budget caps` table `workspace_id` + `cap_usd` + `period: monthly`, dispatch pause when exceeded, tRPC `getSpend` + UI `Settings → AI → Budgets`.
+2. **DAG visualization** `Task-convoy-dag-visualization` — `components/mission-control/convoy-dag.tsx` small DAG for `ready/in_progress` brief `sliceDependencies`, `GET /mission-control?dag=1` panel.
+3. **Automation tiers** `Task-automation-tiers` — `automation_tier enum: manual|assist|auto` per convoy or workspace, `convoys.create` adds `tier`, Mission control badge.
+4. **Repo preflight** `Task-repo-setup-preflight` — `POST /api/connected-repos/preflight` checks `git ls-remote` + `worktree` writability before clone, UI shows result.
+5. **PR checks recovery panel** `Task-pr-checks-recovery-panel` — reuses webhook `prUrl`, shows checks status + `Retry` button (calls forge adapter `getChecks` stub).
+
+Out of scope: Epic 11 screenshot capture (needs browser), full LiteLLM.

+## Roles invoked

+## Todos
+
+- [ ] Brief 1 cost caps
+- [ ] Brief 2 DAG viz
+- [ ] Brief 3 tiers
+- [ ] Brief 4 preflight
+- [ ] Brief 5 checks panel
+
+## IA
+
+Skipped (`ia` in skip). New table only for budget caps; DAG/tiers reuse `objects.content`.
+
+## UX
+
+Partial — `ux` not skipped for DAG: simple SVG, not full canvas.

+# Brief 1 — `Task-cost-budget-ui-and-caps` (Epic 1 follow-on)
+
+## Goal
+
+Month-to-date spend per alias/tier visible, caps pause dispatch when exceeded. Autensa benchmark row `cost tracking & budget caps` `plans/Plan-automation-foundation/Plan-automation-foundation.md:236`.
+
+## Files
+
+- `packages/database/src/schema/budget_caps.ts` NEW — `id uuid, workspace_id fk, cap_usd numeric(12,2), period varchar monthly, enabled bool, created_at`. + `spend_ledger` view or `convoy_events` sum query.
+- `apps/web/server/routers/budgets.ts` NEW — `getSpend(workspaceId)` sums `convoy_events.estimated_cost_usd` month-to-date grouped by `model_alias`; `getCap`/`upsertCap`/`deleteCap` admin only; `shouldPauseDispatch` helper for orchestrator.
+- `apps/orchestrator/src/tick.ts` — call `shouldPauseDispatch` before `enqueueJob`, return `pause` action when cap exceeded.
+- `apps/web/app/(app)/[workspaceSlug]/settings/ai/budgets/page.tsx` NEW — table cap + spend chart (simple bar), Test.
+
+## Acceptance
+
+- `/settings/ai/budgets` shows MTD $42/$100 (example), `upsertCap cap_usd:100` → orchestrator `tick` returns `pause reason: budget cap` when sum > cap.
+- `pnpm lint && pnpm type-check` pass.
+
+## Prompt
+
+You are `role-implementer` brief 1. Read `plans/Plan-automation-foundation/Epic-model-provider-registry/Task-cost-budget-ui-and-caps.md`, `packages/database/src/schema/convoy_events.ts`, `apps/orchestrator/src/tick.ts`, `docs/adr-model-routing.md`. Keep ledger query simple (sum `estimated_cost_usd` where `occurred_at >= month_start`).
+
+## Depends
+
+None.
