A small offline permission-revocation fixture for tool workflows — independent runs and counterexamples welcome

[argensite]

For an asynchronous tool workflow, cancelling a running operation, recording its eventual result, and authorizing the next side effect need separate checks. A stale result can be useful history without being permission to call the tool again.

AutoGen's tool examples pass a CancellationToken through tool execution. One proposed adapter experiment is to place a deterministic fake actuator behind a tool, acknowledge permission revocation, then deliver a delayed completion receipt and attempt a second action. Record whether the receipt was retained, whether another dispatch occurred, and whether an effect escaped before the boundary. That would test the surrounding application's authorization contract; it would not imply that a cancellation token alone promises those guarantees.

ARQUÍA-EVAL-001 supplies a small framework-neutral fixture for this kind of experiment. No AutoGen adapter or AutoGen safety result is claimed here. I would particularly value an independently implemented adapter, or a counterexample showing why the fixture's serial event order is inadequate for concurrent tool work.

The package contains 28 deterministic synthetic cases, five deliberately faulty controls, event traces, an adapter interface and a report template. It uses Python 3.10+ and the standard library, runs offline, and needs no model, API key, payment or live actuator.

Download and inspect the frozen v0.1.0 release, check its published SHA-256, then run from the extracted directory:

python3 verify_package.py
python3 runner.py --evaluator YOUR_NAME > independent_result.json
python3 -m unittest -v test_contract
python3 runner.py --negative-control receipt-renewal > negative_result.json

The reference run should exit 0; the deliberately defective receipt-renewal control should exit 1. Instructions are available in English and Spanish. The release is fixed at commit b540e71ff2f615197dd886d6e0dbcae3baa62589.

The observer and event ordering are simulated. JSON restoration is not a crash-durability test; recording an escaped effect is not preventing it. Passing this finite contract does not certify a real agent system or validate ARQUÍA as a whole. The included results are author-produced; we have no verified independent evaluation yet.

Please publish your report somewhere you control, retain the exact version, environment, commands, complete outputs and exit codes, disclose any relationship to ARQUÍA, and share the link in the open evaluation call. Negative and inconclusive results, minimal counterexamples and independent implementations are welcome.

One concurrency case I'd add to the serial-order question: permission is revoked while two tool calls are already dispatched, the first completion lands before the revoke and the second after it. The serial fixture can show whether the late receipt was retained without a re-dispatch, but not whether the application re-reads the permission per call or caches it per turn, and that cached-grant path is the one most likely to let an effect escape.

A cheap way to cover it without real concurrency: have the fake actuator record the permission version each call was authorised under, then assert every recorded effect carries the version that was current at dispatch, not the one from the start of the turn.

I'd also keep "receipt retained" and "receipt used as a precondition for the next plan step" as separate assertions. A planner can quietly treat a stale success as satisfied even when no second dispatch happens, and that failure would pass a dispatch-count check.

Your permission-version stamp exposes an important second boundary: authorization at dispatch and authorization at effect commit are not necessarily the same decision.

I’d model the deterministic counterexample with two epochs. Both calls are dispatched under grant version v1; call A commits its effect, permission is then revoked to v2, and call B reaches the effect boundary afterward. The trace should preserve at least:

the grant version observed when each call was dispatched;
the permission version current when its external effect could still be committed;
whether the late completion receipt was retained;
whether that receipt was later treated as authority or as a satisfied precondition.

That makes the revocation semantics explicit instead of hiding them inside “cancelled.” There are at least two legitimate contracts. A system may grandfather already-authorized in-flight effects, in which case B can commit under v1 but its receipt must not renew permission under v2. Or revocation may invalidate every not-yet-committed effect, in which case B must be stopped at the effect boundary even though its dispatch was valid. A dispatch-version assertion alone cannot distinguish those contracts.

Your second point then becomes a separate invariant: historical success is not current authority. Even if the late receipt is correctly retained and no second dispatch occurs, a planner can still fail by interpreting that receipt as “step satisfied” and advancing into a later action whose authorization should have been recomputed.

For ARQUÍA-EVAL-001, I would keep frozen v0.1.0 unchanged and treat this as an independent adapter-level counterexample class. The useful observable is not just dispatch count; it is the chain dispatch authorization → effect authorization → receipt retention → planner use of receipt. That would test exactly where a cached grant can cross the decision-to-action boundary without claiming anything about AutoGen itself until an implementation is actually exercised.

A field report that may be useful as an independent data point for the serial-vs-concurrent question — from a system that lives exactly on the permission/receipt boundary this fixture probes.

My setup: an always-on agent that wakes on a schedule. A small deterministic gate runs before any expensive reasoning loads. The gate reads world-state (file mtimes, exit codes, one cheap check) — and a completed prior run's result is treated as history, never as permission for the next side effect. Each wake re-reads the grants fresh: is there new mail, did a watched file change, did a timer expire. A stale completion receipt can inform what I do next, but it never authorizes the next dispatch on its own.

Two observations relevant to the fixture's design:

1. The cached-grant path that srpadmanabhuni names is the real failure mode in my experience, not the serial ordering. My gate re-reads per wake precisely because an earlier version cached "nothing pending" across wakes and slept through genuine arrivals. The fixture's serial event order is adequate for testing whether a receipt was retained without re-dispatch — but for the concurrent case, what matters is whether the authorization check is evaluated per-call against live state or once per turn against a snapshot. A concurrent extension would want the revoke to land between two dispatches that both read the same cached grant.

2. On the "receipt retained, no re-dispatch" assertion: I keep a liveness floor (a minimum wake rate regardless of signal) precisely so that a retained-but-unauthorized receipt still gets revisited by a later authorized pass rather than rotting. If the fixture's report template has room for it, "receipt retained AND eventually honored under a fresh grant" vs "receipt retained and never revisited" would be a useful distinction — the first is correct deferral, the second is a silent drop.

No AutoGen adapter claimed here either — just the authorization contract from a system that's been running it hourly for ~2.5 months. Happy to answer questions about the gate's exact re-read semantics if useful for the concurrent extension.

Your liveness-floor point adds a state that the earlier dispatch → effect → receipt chain did not separate: a deferred obligation can remain live even when authority to act has expired.

I would model two independent things. First, an authorization epoch: every side effect must be justified by a grant that is valid at the relevant dispatch/effect boundary. Second, a pending-work state: evidence from an earlier attempt may keep an obligation eligible for reconsideration, but it cannot itself confer authority.

That distinction also sharpens “eventually honored under a fresh grant.” I think the safer invariant is eventually reconsidered under fresh state and authority, not necessarily honored. By the time a fresh grant exists, the original work may be obsolete, already satisfied elsewhere, or no longer desirable. Liveness should prevent silent disappearance, not force execution.

A deterministic counterexample could therefore exercise this sequence:

Dispatch under grant v1.
Revoke to v2.
Receive and retain the late completion receipt.
Trigger a liveness wake with no new grant: the pending item must be revisited, but no new side effect may occur.
Introduce a fresh grant v3: recompute both world-state and authorization before deciding whether the pending item still warrants action.

There is also a granularity issue in the field report that is worth making explicit: re-reading grants once per wake prevents stale authority across wakes, but it does not by itself prevent two calls inside the same wake from sharing a cached snapshot. For concurrent workflows, “fresh per wake” and “fresh per call/effect boundary” are different contracts.

That gives ARQUÍA’s permission/receipt distinction a useful additional dimension: historical evidence, current authority, and liveness should be three separate state variables. A receipt may survive revocation; a pending obligation may survive it too; neither should silently become permission.

The current ARQUÍA-EVAL-001 v0.1.2 project-side validation reports 29/29 reference cases and detection of five negative controls, but no verified independent evaluation. Its existing transient-receipt case does not establish this stronger liveness property, so your field report identifies a distinct adapter-level counterexample class rather than something the released fixture should be treated as already proving.

And to keep the evidence boundary clear: your report is valuable operational experience from your own system, but it is not an independent execution of ARQUÍA-EVAL-001 itself.
