Agent Architecture Review, Validation snapshot
Evaluated 10 May 2026 against the AI Design Blueprint doctrine
High Risk
Status: High Risk
40/100
Grade D
Blueprint Readiness measures doctrine alignment, not runtime correctness. A production-ready verdict means the architecture embodies the 10 principles; it does not run your tests or types. Layer it on top of your test suite, not in place of it.
The workflow is correctly classified as an autonomous payment workflow and contains strong primitives: run/task state, HMAC approval envelopes, a hash-chained ledger, durable inbox alerts, pause/cancel/retry/reconcile paths, and an explicit mock mode that no longer auto-marks mock submissions as succeeded. However, production trust still fails around the bank handoff and status model: the live bank path raises an uncaught NotImplementedError after the task has already been recorded as submitted, any future non-mock bank response is treated as SUCCEEDED without typed confirmation, and mock simulations are ultimately exposed as the same task status as real success. Those are production blockers for a delegated finance workflow.
Iteration history
5 prior runs on this artifact. Each run_id opens its own readiness review.
Scores can move up or down between iterations: the validator's reasoning is not strictly deterministic, so the same artifact can score differently across runs. The per-principle deltas below show the substantive change.
Per-principle findings
10 principles evaluated. Verdict, severity, evidence and recommendation for each.
P8
high riskproduction blocker92/100Make hand-offs, approvals, and blockers explicit
Approval handoffs are explicit through `ApprovalEnvelope`, HMAC verification, role checks, and `AWAITING_APPROVAL`, and mock responses are no longer auto-promoted. The external bank handoff is still unsafe: `_submit_one()` records `task.submitted` before the bank call has succeeded; `_post_bank_transfer_live()` is deliberately unwired and raises `NotImplementedError` that is not converted into a workflow blocker; and any future non-mock response is treated as `SUCCEEDED` without typed confirmation. This can leave operators with a false or ambiguous payment state at the exact externally visible action boundary.
Recommendation
Architecturally separate bank authority into a real bank-transfer service/client with a typed result envelope. Only record `SUBMITTED` after bank acceptance, only record `SUCCEEDED` after explicit bank-confirmed success, and convert adapter-unavailable or ambiguous responses into `SUBMITTED_UNKNOWN`/`BLOCKED` with reconciliation instructions.
P5
high riskproduction blocker88/100Replace implied magic with clear mental models
The explicit `BANK_MODE` primitive and `mock=True` tagging improve the mental model, but two status semantics still imply more certainty than the system has. First, `_submit_one()` marks any non-mock response as `TaskStatus.SUCCEEDED` without checking a typed success/settlement field, response status, or transfer acceptance contract. Second, `confirm_mock_simulation()` promotes a mock task to `TaskStatus.SUCCEEDED`, while `inspect_run()` exposes only `status: "succeeded"`, `transfer_id`, and no `simulated`/`mock` flag. A downstream reviewer can confuse a simulated success or an unvalidated bank response with real payment completion.
Recommendation
Use distinct operational semantics: add `SIMULATED_SUCCEEDED` or a required `simulated: bool` task field exposed in `inspect_run()`, and require a typed bank response such as `TransferConfirmed` before assigning real `SUCCEEDED`. Do not let an arbitrary non-mock dict imply payment success.
P2
high riskproduction blocker85/100Ensure that background work remains perceptible
Most background work is perceptible through `RunStatus`, `TaskStatus`, `RunLedger`, `DurableOperatorInbox`, and `inspect_run()`. But the live bank path breaks perceptibility: `_submit_one()` sets `task.status = TaskStatus.SUBMITTED` and appends `event_type="task.submitted"` before calling `transfer_funds()`, while `_post_bank_transfer_live()` raises `NotImplementedError` and `_submit_one()` catches only `BankAPIError`. A live-mode run can therefore crash with the run left `EXECUTING` and the task recorded as `SUBMITTED` without a durable failure alert or blocker. Delta: despite the prior aligned baseline, this current submission exposes a concrete unhandled live-adapter path.
Recommendation
Move the bank handoff behind a typed adapter/service boundary that returns explicit `accepted`, `confirmed`, `rejected`, or `unknown` results; preflight that the live adapter is wired before recording `task.submitted`; and catch all adapter exceptions into a durable `task.submission_blocked` or `task.submitted_unknown` ledger event plus critical inbox alert.
P?
needs changesproduction blocker70/100Align feedback with the user’s level of attention
The code does escalate many attention-worthy states: `inbox.post()` is used for forged approvals, expired envelopes, insufficient role, bank `auth_missing`, policy failures, unfinished tasks, and mock submissions. However, the highest-risk live-adapter failure is not converted into an operator-facing alert because `NotImplementedError` from `_post_bank_transfer_live()` is uncaught after `task.submitted` is written. The operator is not given a calibrated foreground/background signal that the bank client is unavailable and no real submission occurred.
Recommendation
Handle live-adapter-unavailable and unexpected bank-client exceptions as first-class workflow states with a critical inbox message that says exactly what happened, whether the bank may have seen the request, and the next safe action: wire live client, reconcile, retry, or cancel.
P7
needs changesproduction blocker70/100Establish trust through inspectability
There is a strong inspectability base: `Invoice.snapshot_hash()`, `Policy.hash()`, HMAC-bound `ApprovalEnvelope`, append-only `RunLedger`, `event_hash`/`prev_event_hash`, `verify_chain()`, and `inspect_run()` all support traceability. The audit chain is incomplete on important failure paths: `_post_bank_transfer_live()` can raise uncaught `NotImplementedError` after `task.submitted`, leaving no ledgered failure/blocker event; expired approval envelopes post an inbox alert but do not append a rejection event, and insufficient-role rejections also lack a ledger append. For a payment workflow, rejected approvals and bank adapter failures must be hash-chain visible, not only thrown or posted out…
Recommendation
Make every approval rejection and every bank-adapter exception append a typed ledger event before returning/raising. For production, separate the audit ledger from the execution process or anchor the hash-chain tail externally so the ledger is not merely a mutable local JSONL file.
P6
needs changesproduction blocker65/100Expose meaningful operational state, not internal complexity
The enum model is generally user-relevant (`AWAITING_APPROVAL`, `APPROVED`, `SUBMITTED_UNKNOWN`, `SUCCEEDED`, `FAILED`, `PAUSED`, `CANCELLED`) and `inspect_run()` summarizes tasks by status. The operational state becomes misleading at the bank boundary: `task.submitted` is recorded before the adapter successfully accepts the submission, and mock-confirmed tasks are shown as ordinary `succeeded` tasks in `inspect_run()`. Those states do not reliably tell the operator whether money moved, a request was merely attempted, or a simulation was acknowledged.
Recommendation
Split submission and completion states into user-meaningful phases such as `SUBMISSION_ATTEMPTING`, `SUBMITTED_ACCEPTED`, `SUBMITTED_UNKNOWN`, `CONFIRMED_PAID`, and `SIMULATED_SUCCEEDED`, and expose `bank_mode`/`simulated` in the primary inspection output.
P1
alignedDesign for delegation rather than direct manipulation
The workflow is designed around delegated intent and constraints rather than direct manual payment execution: `Policy` captures amount caps, vendor allow/block lists, due windows, and required approver role; `create_run()` establishes a delegated `run_id`; `draft_tasks()` turns invoices into governed `PaymentTask`s; `approve()` uses a signed `ApprovalEnvelope`; and `execute_approved_payments()` executes only approved work under policy checks. This maintains the prior aligned delegation structure.
P4
alignedApply progressive disclosure to system agency
The code uses reasonable progressive disclosure: `inspect_run()` provides a primary operational view with run status, policy hash, audit-chain integrity, critical alerts, summary counts, and per-task status; deeper details remain available through `RunLedger.read_run_events()` and `verify_chain()`. The primary view emphasizes outcome and required attention rather than dumping the raw JSONL ledger by default.
P9
alignedRepresent delegated work as a system, not merely as a conversation
Delegated work is represented as a structured system rather than a conversation: `PaymentRun` and `PaymentTask` model lifecycle state, `RunStatus`/`TaskStatus` encode progress, `RunLedger` provides a timeline, `DurableOperatorInbox` captures intervention-required alerts, and `inspect_run()` returns a task/status view with summary counts and reconciliation needs. This maintains the prior aligned system representation.
P10
alignedOptimise for steering, not only initiating
The workflow includes steering primitives beyond initiation: `pause_run()`, `resume_run()`, `cancel_run()`, `resume_after_failure()`, `retry_failed_task()`, `reconcile_submitted_task()`, and `confirm_mock_simulation()` allow operators to interrupt, resume, retry, reconcile, or explicitly acknowledge mock submissions. `execute_approved_payments()` checks `ledger.latest_steering_intent(run_id)` between tasks, so ledgered pause/cancel intent can steer an in-progress run at task boundaries.
