From f5d232bd1f2ba64f266e1e9b247466a3a46029a1 Mon Sep 17 00:00:00 2001 From: Graeme Foster <80714+GraemeF@users.noreply.github.com> Date: Sat, 13 Jun 2026 11:04:35 +0100 Subject: [PATCH] Gate the 7 structural live-contract holdouts behind capability flags MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The live zulip ContractFactory (comms-e5vm.5, PR #11) runs the AgentComms contract against a real realm at 38/45. The 7 holdouts are structural properties of any real Zulip — integer-second timestamps and a minter-side is:mentioned narrow keyed to the queue owner — not factory-fixable, and all covered elsewhere (memory/fake + realm.live.test.ts). They reported as 7 spurious failures: a broken window. Add two optional ContractEnv capability flags, following the existing newUnacquiredAdapter omission pattern (optional field, early-return gate, substrate-neutral — memory/fake leave them unset and run all 45): - coarseTimestamps gates the 4 range/replay tests that need distinct per-message timestamps. - noSelfEventDelivery gates the 3 event tests where a bot must observe its own post/mention on its own inbox in the contract's window. The live factory sets both true, so bun run test:live reports a clean green applicable subset. A future owned/ephemeral realm that delivers self-events flips noSelfEventDelivery false and recovers those 3. --- packages/testing/contract.ts | 30 ++++++++++++++++++++++++++++ packages/zulip/contract.live.test.ts | 8 ++++++++ 2 files changed, 38 insertions(+) diff --git a/packages/testing/contract.ts b/packages/testing/contract.ts index 9142d48..465ab7d 100644 --- a/packages/testing/contract.ts +++ b/packages/testing/contract.ts @@ -75,6 +75,29 @@ export interface ContractEnv { * allowlist mode) opt in by setting it. */ readonly unacquirableName?: string + /** + * Optional.
