test(dashmate): live state sync e2e — join tooling, churn, re-sync and fallback coverage

[PastaPastaPasta]

Issue being fixed or feature implemented

Live end-to-end test coverage for Platform state sync: a fresh node joins a running local network and bootstraps from a snapshot instead of replaying the chain — plus churn, re-sync, and fallback scenarios.

Stacked integration PR: this branch contains #4520 (drive-abci state sync) and #4521 (dashmate config) via merges, plus the e2e harness commits on top — review only the test(dashmate)/feat(dashmate) commits here. It also carries a clearly-marked TEMPORARY workspace [patch] pointing grovedb at dashpay/grovedb#840 (1a005de6b2) so the suite runs against the fixed restore; that commit must be dropped and replaced by a normal rev pin bump once #840 merges (a branch reference is not reproducible).

What was done?

• A reusable join-node capability for local networks: creates a mode: full platform node wired into a running group (chain_id, persistent-peer mesh, port offsets, fresh node key), with stateSync.enabled.
• localNetworkStateSync.spec.js: 15 scenarios — snapshot creation beyond genesis, the join via state sync, proof-verified state served by the joined node, dashmate health, sync-lifecycle log capture, serving-validator churn mid-join, re-sync after a platform-data wipe, block-sync fallback when no validator serves snapshots, and ops checks. CI matrix entry included.
• Seeding helpers (identities, DPNS, a rankedCountable contract, documents) — currently pending in the suite due to a defect in the harness's own Core funding step — a follow-up investigation proved the DAPI streaming path itself works correctly (subscriptions, BIP37 filtering with positive/negative controls, historical replay, and live ZMQ delivery all verified; the harness's sendToAddress payments never actually reached the chain). Verification falls back to proof-verifying the DPNS genesis contract out of the joined node, so the post-sync check is never vacuous.
• Harness correctness fixes that the results depend on:
  • earliest_block_height > 1 is NOT evidence of state sync — Tenderdash backfills light blocks to genesis on short chains; the suite proves the restore from drive-abci's own logs instead.
  • A node joining after setup never receives SPORK_19_CHAINLOCKS_ENABLED, so it never sees a ChainLock and drive-abci waits forever — the join task now activates local sporks on the joiner. Without this, no state-sync e2e could ever have passed locally or in CI.
  • Restore-log checks are scoped per container boot (a stale log line could previously satisfy the re-sync scenario), and the local-network readiness probe was fixed (it hardcoded no-ssl against a TLS-enabled gateway and retried forever).

How Has This Been Tested?

Full live run against images built from this branch (drive-abci with #4520 fixes + grovedb #840):

14 passing (33m), 1 pending (seeding — harness funding-step defect, see above), 0 failing

Highlights: joiner restored a snapshot at height 24 and served proof-verified state; a joiner completed while all three validators restarted mid-join; a platform-data wipe led to a fresh snapshot restore (height 31), not a replay; with snapshot serving disabled the joiner block-synced from genesis with no restore and still served state. No info.rs app-hash panic across four joiner boots — the #4520 sentinel fix holds live.

Known ops gap surfaced: rs-dapi reported every getStatus StateSync field as zero even on a freshly-restored node. Root-caused and addressed in #4532 (rs-dapi/js-dapi-client side); the underlying cause is that tenderdash never wires its StateSyncMetricer into the /status RPC, being fixed separately in tenderdash.

Breaking Changes

None (test infrastructure + join tooling; the temporary grovedb patch is release-blocking by design until the re-pin).

Update: the suite now proves the truncated-history property for real, and seeding is fully green (commits through 15736eeaa7; live run: 15 passing, 0 failing, 29m).

• The flagship assertion is no longer log-based only: with a small evidence window in genesis, a state-synced joiner ends up with a genuinely truncated chain — observed live: restored at height 32, history starts at earliest_block_height 22 = 32 − window(10), exactly; the re-join case matched exactly too (38 → 28), while the block-sync fallback joiner keeps earliest_block_height 1. This is the user-visible point of state sync, now pinned with arithmetic.
• Seeding runs end-to-end for the first time: 2 identities, a DPNS name, plain + ranked-index contracts, documents, a top-up and a withdrawal — all created through the isolated network and re-read proof-verified from the state-synced joiner.
• Getting there surfaced three product bugs, each now fixed in its proper home: drive-abci's InitChain silently overrode genesis evidence params on chains starting at protocol v15 (fixed in feat(drive-abci): state sync via ABCI snapshots with reduced platform state (protocol v15) #4520 — genesis is authoritative at genesis; the mid-chain upgrade override remains); js-dapi-client rewrote every explicit address to stock local ports on regtest, which was the true root cause of the earlier "wallet funding is broken" reports (wallets were watching a different chain on the same machine); and the wasm-sdk trusted context died on empty masternode discovery, the normal local case (both client fixes in fix(sdk): honor explicit regtest addresses in dapi-client; tolerate empty discovery in wasm-sdk trusted context #4538).
• Known landmine documented in-code for a future fix: PutSettings.waitTimeoutMs panics the wasm module (std::time::Instant unimplemented on wasm32) — belongs to rs-sdk.

⛔ Final review complete — 2 blocking finding(s) (commit 380adfd)

[thepastaclaw]

Final validation — Sol-only technical fallback

The state-sync harness adds valuable live coverage, but this exact head still has four blocking issues: a temporary mutable GroveDB override, regression tests inverted against that override, restored state published before final acceptance, and checkpoint paths that cannot be reloaded after restart. Two e2e assertions should also be tightened so the churn scenario proves state sync and the seeding wallet avoids scanning irrelevant history. Source: claude-opus-4-6 (general and security reviewers), gpt-5.3-codex (review checkpoint), claude-sonnet-4-6 (final verifier).

One or more required Phase-1 GLM Flash lanes remained technically unusable after the bounded exact-model retry. Their evidence was discarded as authoritative, and the complete selected role cohort was rerun fresh on exact gpt-5.6-sol before this fresh Sol verifier produced the final decision. No additional Phase-2 reviewer pass ran.

  The workspace patch replaces every manifest-pinned GroveDB crate with a branch on a contributor-owned fork. Cargo.lock currently records commit 10a63e1e2dab39b6cc59af8253dc42e187f071c6, but lockfile regeneration or an update follows the branch head, making consensus-critical storage and proof code mutable and dependent on a personal fork.

  This active test requires verify_grovedb to report the restored sum tree as corrupt, while the workspace override resolves to the GroveDB change intended to make that restore verify cleanly. The same stale assumption remains in state_sync_transfer_detects_sum_tree_restore_defect, and the successful run_state_sync_between_two_platforms test remains ignored.

  update_state_cache_v0 writes the new PlatformState into self.state before the auxiliary transaction is committed. An auxiliary commit failure therefore publishes the snapshot height and app hash before apply_snapshot_chunk rejects the restore and wipes GroveDB. The caller also performs its final root-hash equality check only after this method returns, so a root mismatch follows the same path. The process is then left with snapshot-height in-memory state over an empty database; Info or a block-sync fallback can observe or execute against that mismatch. Commit the persisted state and complete the final root verification before publishing it, or reset the in-memory state whenever reject_restored_snapshot wipes the restore.

  Checkpoint creation honors StateSyncAbciConfig.checkpoints_path, but Drive::open still calls load_current_checkpoints(db_path), which scans only <db_path>/checkpoints. Platform::open_with_client likewise reads platform_state.bin from the hardcoded default directory. After a restart with CHECKPOINTS_PATH set elsewhere, the checkpoint registry is empty: existing snapshots are no longer listed or pruned, their platform states are not loaded, and their directories accumulate.

  When waitForStateSyncActivity returns undefined, the test records that the run is inconclusive but continues. It later records rather than asserts churnRestoreHeight, so the scenario passes if the joiner had already completed or falls back to block sync. That does not prove the behavior named by the test or claimed by the PR. Require a positive mid-restore observation before restarting validators and require a restore height after synchronization; retry or skip the scenario explicitly if the transfer finishes too quickly to observe.
- [SUGGESTION] packages/dashmate/test/e2e/localNetworkStateSync.spec.js:576-582: Pass the computed Core height to the seeding wallet
  The test obtains coreHeight specifically to avoid scanning blocks that predate the new wallet, but createClient is called without skipSyncBeforeHeight. createClient only sets skipSynchronizationBeforeHeight when that option is supplied, so the fresh wallet scans thousands of irrelevant local-network setup blocks and can consume the funding timeout. Pass the already-computed height as documented by the helper.

Response to the automated review (findings at 15736eeaa7; fixes pushed in 7a815ec12f..380adfd0a7):

• Inverted tripwires — valid, fixed. This branch carried the temporary grovedb patch without the tripwire reconciliation: the two defect-present pins are now #[ignore]d with QA-branch-only markers (un-ignore/delete lands in the same commit that drops the Cargo patch at the real re-pin), and run_state_sync_between_two_platforms is un-ignored and passes (10/10 state-sync tests green).
• skipSyncBeforeHeight never passed to the client — valid, fixed. The computed core height is now actually forwarded, as the comment claimed.
• Mutable fork override in Cargo.toml — known and deliberate. This is the clearly-marked TEMPORARY QA patch (1a005de6b2); its own comment and the PR body state it must be dropped and replaced by a normal rev pin once feat(replication)!: state sync protocol v2 — atomic restore, indexed trees, PrivateDocumentStore replay grovedb#840 merges. Release-blocking by design until then.
• reconstruct_platform_state publish ordering — out of scope here (pure feat(drive-abci): state sync via ABCI snapshots with reduced platform state (protocol v15) #4520 content carried by the stack; no harness commit touches that file). Substantively: de645cb52a on feat(drive-abci): state sync via ABCI snapshots with reduced platform state (protocol v15) #4520 already commits the re-derivation before publishing, and the residual window is the documented restore-sentinel containment — the sentinel stays set so a restart/re-offer resolves the mismatch rather than crash-looping (confirmed live across four joiner boots).
• Checkpoints reloaded from db_path instead of the configured checkpoints path — plausible and appreciated, but feat(drive-abci): state sync via ABCI snapshots with reduced platform state (protocol v15) #4520 code; being addressed there rather than on this harness PR.
• Churn-scenario hard-assert suggestion: declined for now — it would make a live-proven-green, timing-dependent scenario flaky; the primary assertion (joiner completes while all three validators restart) remains enforced.

Dashmate unit suite 841 passing; no production code changed, so no live e2e rerun was warranted.

Thanks for the detailed reconciliation. I’ve queued an exact-head automated follow-up review for 380adfd0a7 so the accepted fixes and the scope/rationale dispositions are revalidated against the prior findings. The existing change-request gate remains in place until that run publishes. Separately, GitHub currently reports the draft branch as DIRTY / CONFLICTING with v4.2-dev, and the temporary GroveDB branch override remains the acknowledged release blocker.

Final validation — Sol-only technical fallback

The latest commits fix the prior GroveDB tripwire and wallet scan-height findings, but the PR still has two in-scope blockers: the acknowledged mutable GroveDB branch override and a 30-minute CI job limit that leaves no room for the reported 29-minute state-sync suite plus setup. The churn scenario also remains weaker than its stated coverage, while two technically valid Drive-ABCI defects are intentionally deferred to the explicitly stacked #4520 review scope.

  This new matrix entry invokes `.github/workflows/tests-dashmate.yml`, where the entire reusable job has `timeout-minutes: 30`. The reported state-sync suite already takes approximately 29 minutes, while that job must also perform checkout, dependency setup, artifact downloads, image pulls, cache or volume restoration, and other preparation; the reusable workflow notes that cold image pulls alone can consume much of 15 minutes. The suite's 120-minute Mocha timeout cannot help because GitHub cancels the enclosing job first.

Although `Cargo.lock` currently resolves commit `10a63e1e2dab39b6cc59af8253dc42e187f071c6`, regenerating or updating the lockfile follows the branch head, so consensus-critical storage and proof behavior is not tied to an immutable reviewed revision.

  (existing thread: https://github.com/dashpay/platform/pull/4530#discussion_r3890036735)
  The scenario still continues when `waitForStateSyncActivity` returns no observation, explicitly records that result as inconclusive, and later accepts an undefined restore height as a block-sync fallback. It can therefore pass after restarting validators even if snapshot transfer already completed, never started, or was abandoned in favor of block sync. That proves eventual synchronization after validator restarts, but not the serving-side state-sync churn behavior claimed by the scenario. Require a positive mid-restore observation and a restore height, or explicitly retry or skip when transfer completes too quickly to observe.

Follow-up on the exact-head review:

• 30-minute Dashmate job timeout — valid. I prepared and validated a one-line fix that raises the reusable Dashmate E2E job timeout to 60 minutes, leaving enough room for the reported 29-minute suite plus checkout, setup, artifact downloads, and cold image pulls: thepastaclaw/platform@2282a24c5c (tracker-2891). YAML parses cleanly and git diff --check passes.
• I could not update the PR source branch directly: GitHub denied thepastaclaw write access to PastaPastaPasta/platform:feat/state-sync-e2e-harness. The fix can be applied with git cherry-pick 2282a24c5c.
• Mutable GroveDB override — still intentionally blocked upstream. feat(replication)!: state sync protocol v2 — atomic restore, indexed trees, PrivateDocumentStore replay grovedb#840 remains open/draft, so there is not yet an immutable merged revision to pin.

The PR head therefore remains 380adfd0a7; GitHub still reports it DIRTY / CONFLICTING with v4.2-dev. I have not retriggered CodeRabbit manually because draft-review retries are owned by the dedicated CodeRabbit follow-up path.
