From 332547716019958b788d35d997755cf424122176 Mon Sep 17 00:00:00 2001 From: Bojan Date: Wed, 29 Apr 2026 19:29:21 +0200 Subject: [PATCH 1/2] fix(pipeline): publisher fencing/WAL + agent gossip + network-sim parity MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes the data-pipeline layer of the bug-fix backlog from PR #327. Slice 4 of 4 (split by architectural layer for reviewability) — the heaviest slice because the publisher↔agent gossip flow cross-cuts the most fixtures. Publisher bug fixes - P-2: fencing token in dkg-publisher.ts. Concurrent publish requests could step on each other's WAL entries; now each publish acquires a monotonic fencing token, and the WAL recovery path rejects entries whose token is older than the latest known. - chain-event-poller.ts: transient-error classification. Network blips now get retried with backoff instead of bubbling as fatal; permanent errors still surface. - async-lift-publisher-impl.ts: tighter key-bound subtraction so the lift accumulator can't drift across cg boundaries. - update-handler.ts: r23-4 fix — don't double-emit on the publish retry path. Agent bug fixes - A-5: gossip envelope signing in dkg-agent.ts (the canonicalisation step previously dropped optional fields, causing signature mismatches on round-trip through the network-sim). - A-7: DID-format validation hardened in endorse.ts — accept the full did:* spec rather than the v9 short-form only. - A-12 / A-13: workspace-config validation now catches missing cg-private-key + asymmetric per-cg overrides at config-load time rather than at first publish (much better operator UX). - A-15: signed-gossip-publish egress now includes the cg-id binding so a malicious peer can't replay a signed envelope to a different cg. Network-sim - K-4 / K-5: deterministic RNG + libp2p parity in sim-engine.ts. The sim previously seeded its RNG from Math.random(), making test failures non-reproducible. Also, the gossip-fanout topology diverged from real libp2p peer-selection; now matches the pubsub.gossipsub heartbeat semantics so sim-only passes can't lie about real-network behaviour. (These are the K-4/K-5 sentinels documented in .test-audit/BUGS_FOUND.md.) Tests added - publisher/test/wal-recovery.test.ts (new, +1320 lines): full P-2 fencing-token lifecycle including crash/restore, concurrent-writer starvation, and out-of-order replay rejection. - publisher/test/chain-event-poller-r24-4.test.ts (new, +478 lines): transient-vs-fatal classification matrix. - publisher/test/chain-event-poller-transient-classifier.test.ts (new, +214 lines): unit-level coverage for the classifier itself. - publisher/test/async-lift-subtraction-key-bound.test.ts (new, +167): the cg-boundary regression for async-lift. - publisher/test/per-cg-quorum-state.test.ts (new, +245). - publisher/test/update-handler-r23-4.test.ts (new, +132). - agent/test/op-wallets-and-workspace-config.test.ts (new, +503): A-12/A-13 operator-config validation matrix. - agent/test/per-cg-quorum-rpc-failure-extra.test.ts (new, +177): RPC-failure isolation per cg quorum. - agent/test/signed-gossip-publish-egress.test.ts (new, +150): A-15 cg-id binding on egress. - agent/test/strict-gossip-envelope-extra.test.ts (new, +106): A-5 envelope canonicalisation regression. - agent/test/finalization-handler.test.ts (new, +103). - agent/test/wm-multi-agent-isolation-extra.test.ts (+393): expanded isolation coverage. - network-sim/test/network-sim-extra.test.ts (+187): K-4/K-5 deterministic-RNG + parity assertions. Coverage ratchet - tornadoAgentCoverage 67/68/57/66 → 75/78/63/74. Sequencing: this is PR 4 of 4 — the final and largest slice. PR 1 (#331) contracts+chain, PR 2 (#332) storage+query, PR 3 (#333) operator surface. This PR sits on top of those layers and may need a clean rebase if any of them merge first.

On slower CI runners the verification didn't resolve before the assertions ran, so the test false-failed. Switched to a 10ms-poll `waitFor(predicate, timeoutMs)` helper that polls the observable we are about to assert against. Faster on the happy path AND immune to the race. Belongs in this PR because the race is on the agent/publisher gossip-publish path covered by slice 4.
