Phase 1 — policy kernel and read-only REST

Execute Phase 1 of specs/ArchitectureBlueprint.md: a service skeleton with a shared decide(tool, args, claims) → Allow|Deny policy kernel and a minimal REST surface for org/accounts/transactions/snapshot. No MCP yet (Phase 2). No spend or volume-cost tools — default deny.

Depends on: live OpenBao path tenants/binky/qonto-api (BINKY-WP-0005 / CCR-2026-0008) — already provisioned.

Task: Choose runtime skeleton and layout

id: QONTO-WP-0002-T01
status: todo
priority: high
state_hub_task_id: "f9e129f3-5bd4-43e1-b7a0-281e4d3dec2a"

Pick implementation stack (recommendation: Python 3.12 + FastAPI unless a fleet standard dictates otherwise). Scaffold package layout, pyproject.toml (or equivalent), Makefile targets (test, lint, run), and document commands in AGENTS.md / complete QONTO-WP-0001-T02.

Done when: make test (or documented equivalent) runs an empty/smoke suite; layout matches blueprint components (policy, qonto client, api, audit).

Task: Policy kernel — default-deny no-spend / no-volume-cost

id: QONTO-WP-0002-T02
status: todo
priority: high
state_hub_task_id: "552ff651-dc66-4e65-97fe-3ec26652bbdd"

Implement declarative policy (YAML or equivalent) + pure decision function:

  • default deny
  • allow only v1 read capability ids (org_summary, list_transactions, cost_run_rate_hints / snapshot)
  • hard deny classes: spend, volume_cost, credential_exfil
  • unit tests: allow known reads; deny transfer/card/invoice-shaped tools and suspicious args even if somehow invoked

Done when: policy tests pass in CI/local; no network required.

Task: Qonto REST client (credential inject, no secret log)

id: QONTO-WP-0002-T03
status: todo
priority: high
state_hub_task_id: "be3aa7b6-f28c-4436-bd5d-d6940de6c2ce"

Implement thirdparty client using Authorization: login:key (fields API_USER/API_KEY from env or OpenBao fetch helper). Map:

  • organization + bank accounts
  • paginated transactions with hard caps
  • never log Authorization or key material

Support env inject for tests (QONTO_API_KEY/QONTO_ORGANIZATION_ID or API_KEY/API_USER) and document OpenBao fetch for operators.

Done when: unit tests with mocked HTTP; optional live smoke behind a flag.

Task: REST API surface

id: QONTO-WP-0002-T04
status: todo
priority: high
state_hub_task_id: "678b0b26-15af-4037-849f-d24d320588ac"

Expose JSON endpoints that all run through the policy kernel:

Method Path Capability
GET /v1/health no bank call
GET /v1/accounts org_summary
GET /v1/transactions list_transactions (capped)
GET /v1/snapshot cost/run-rate oriented summary

Done when: OpenAPI or documented curl examples; integration test with mock client; deny paths return 403 with stable error code.

Task: Audit metadata (no secrets)

id: QONTO-WP-0002-T05
status: todo
priority: medium
state_hub_task_id: "4a42dff1-1281-4cc1-ba6a-24702bce7dc9"

Log or emit structured audit events: actor (if present), capability, decision, deny_reason, latency, upstream HTTP status. Never secret fields. Prefer stdout JSON + optional State Hub progress for dogfood runs.

Done when: tests assert secrets absent from log lines for a sample allow/deny.

Task: Operator runbook + CostRunRate refresh path

id: QONTO-WP-0002-T06
status: todo
priority: medium
state_hub_task_id: "7b7ca0f7-f523-473e-b3f6-fe0564f54ed5"

Document how binky-control refreshes finance/CostRunRate.md via GET /v1/snapshot (or equivalent) with OpenBao-backed service start. Link from README. Optional thin script under scripts/.

Done when: runbook in docs/ or README section; dry-run instructions without pasting keys into chat.

Task: Closure review

id: QONTO-WP-0002-T07
status: todo
priority: low
state_hub_task_id: "9b99ba05-99f2-4624-9044-89bf37055434"

Mark workplan finished when T01T06 done; note Phase 2 seed (MCP surface for all harnesses) in closure. Run statehub fix-consistency.
