Every function is pure (no I/O, no clock, no goroutines) so independent reporters challenging the same (target, ticket) pair produce byte-identical StorageProofResult fields. Functions land in two categories: CHAIN-MIRRORED (must match lumera/x/audit/v1/keeper/audit_peer_assignment.go byte-for-byte; the chain re-runs them to validate MsgSubmitEpochReport): - SelectLEP6Targets — 1/3 deterministic target subset (SHA-256(seed||0x00||account||0x00||"challenge_target"), targetCount = ceil(N/divisor) clamped to [1, N]) - PairChallengerToTarget / AssignChallengerTargets — challenger->target pairing (label "pair"), with no-self and lex tie-break SUPERNODE-CANONICAL (chain stores outputs as opaque strings; this file defines the canonical encoding all reporters must use to stay in lockstep): - ClassifyTicketBucket — RECENT/OLD bucket classification using Action.BlockHeight (Action.UpdatedHeight does not exist; see docs/plans/LEP6_SUPERNODE_IMPLEMENTATION_PLAN.md "Resolved Decision 3") - SelectTicketForBucket — deterministic per-(target,bucket) ticket pick with excluded-set support for active heal ops - SelectArtifactClass — LEP-6 §10 weighted roll (20% INDEX / 80% SYMBOL) with deterministic fallback when a class has no artifacts - SelectArtifactOrdinal — uniform ordinal mod artifactCount - ComputeMultiRangeOffsets — k=4 range offsets in [0, size-rangeLen) - ComputeCompoundChallengeHash — BLAKE3 over concat of slices in offset order (lukechampine.com/blake3 to match the chain's library) - DerivationInputHash — canonical hex of derivation inputs - TranscriptHash — full canonical transcript identifier with sorted observer ids; struct-input form prevents field-order mistakes Domain separators ("challenge_target", "pair", "ticket_rank", "artifact_class", "artifact_ordinal", "range_offset", "derivation_input", "transcript") and enum string forms ("INDEX"/ "SYMBOL", "RECENT"/"OLD"/"PROBATION"/"RECHECK") are package constants; freezing them prevents accidental drift between callers and tests. Any change is a protocol-level break that requires versioning. Tests: - TestStorageTruthAssignmentHash_KnownVector locks the byte-level SHA-256 composition against an independent computation, guaranteeing the chain-mirrored helper has not drifted. - TestSelectLEP6Targets_OneThirdCoverage_AssignmentMatchesChain uses the chain's own audit_peer_assignment_test.go fixture (seed="01234567890123456789012345678901", active={sn-a..sn-f}, divisor=3) — output {sn-f, sn-e}. - TestAssignChallengerTargets_KnownAssignment locks the full pairing {sn-a -> sn-f, sn-b -> sn-e}. - TestSelectArtifactClass_WeightedDistribution validates ~20% INDEX over 5000 draws (±2% tolerance). - Determinism, sensitivity, error-path, and out-of-bounds tests for every primitive. Verified: `go test ./pkg/storagechallenge/deterministic/...` passes; the existing deterministic_test.go pre-LEP-6 tests continue to pass. --- pkg/storagechallenge/deterministic/lep6.go | 724 ++++++++++++++++++ .../deterministic/lep6_test.go | 667 ++++++++++++++++ 2 files changed, 1391 insertions(+) create mode 100644 pkg/storagechallenge/deterministic/lep6.go create mode 100644 pkg/storagechallenge/deterministic/lep6_test.go diff --git a/pkg/storagechallenge/deterministic/lep6.go b/pkg/storagechallenge/deterministic/lep6.go new file mode 100644 index 00000000..1a456259 --- /dev/null +++ b/pkg/storagechallenge/deterministic/lep6.go @@ -0,0 +1,724 @@ +// LEP-6 deterministic primitives. +// +// This file implements the off-chain computation library that the supernode's +// storage_challenge runtime, recheck service, and self-healing dispatcher all +// share.

Highlights: - Add compound proof request/response fields and regenerated supernode proto bindings. - Add recipient-side GetCompoundProof handler with signed responses and range validation. - Add challenger-side LEP6Dispatcher for assigned-target dispatch across RECENT/OLD buckets. - Add result buffer implementing host_reporter ProofResultProvider with deterministic chain-cap throttling. - Add deterministic cascade metadata resolution helpers for artifact count, key, and exact artifact size. - Add production ChainTicketProvider backed by final Lumera x/action ListActionsBySuperNode query. - Wire startup to use ChainTicketProvider and cascade metadata/action size resolution instead of NoTicketProvider. - Classify target RPC timeout/no-response as TIMEOUT_OR_NO_RESPONSE and malformed transcripts as INVALID_TRANSCRIPT. - Extend action module bindings/mocks with ListActionsBySuperNode. - Preserve PR1 provider concurrency hardening and PR2 deterministic roocode fixes after rebase.

From: J Bilal rafique <113895287+j-rafique@users.noreply.github.com> Date: Mon, 4 May 2026 20:35:13 +0500 Subject: [PATCH 4/8] feat(self_healing): add LEP-6 chain-driven heal-op dispatch runtime (#289) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replaces the gonode-era peer-watchlist self-healing with a chain-mediated LEP-6 §18-§22 (Workstream C) implementation. Healer reconstructs locally and STAGES (no KAD publish), verifiers fetch reconstructed bytes from the assigned healer over a streaming gRPC RPC (§19 healer-served path) and hash-compare against op.ResultHash, then publish to KAD only after chain VERIFIED quorum. Three-phase flow Phase 1 — RECONSTRUCT (no publish) cascade.RecoveryReseed(PersistArtifacts=false, StagingDir) → download remaining symbols → RaptorQ-decode → verify file hash against Action.DataHash → re-encode → stage symbols+idFiles+layout +reconstructed.bin to ~/.supernode/heal-staging//. Submit MsgClaimHealComplete{HealManifestHash}; chain transitions SCHEDULED → HEALER_REPORTED, sets op.ResultHash = HealManifestHash. Phase 2 — VERIFY (§19 healer-served path) Verifier opens supernode.SelfHealingService/ServeReconstructedArtefacts on the assigned healer (op.HealerSupernodeAccount), streams the reconstructed bytes, computes BLAKE3 base64 (=Action.DataHash recipe via cascadekit.ComputeBlake3DataHashB64), compares against op.ResultHash (NOT Action.DataHash — chain enforces at lumera/x/audit/v1/keeper/msg_storage_truth.go:291), and submits MsgSubmitHealVerification{verified, hash}. Chain quorum n/2+1. Phase 3 — PUBLISH (only on VERIFIED) Finalizer polls heal_claims_submitted (Opt 2b per-op poll, folded into single tick loop alongside healer + verifier dispatch), reads op.Status, calls cascade.PublishStagedArtefacts on VERIFIED (same storeArtefacts path as register/upload), deletes staging on FAILED/EXPIRED. Chain may reschedule a different healer on EXPIRED. Crash-recovery / restart-safety Submit-then-persist ordering: SQLite dedup row is written ONLY after chain has accepted the tx. A failed submit (mempool, signing, chain reject) leaves no row and staging is removed, so the next tick can retry cleanly. If chain accepted a prior submit but the supernode crashed before persisting, the next tick's resubmit fails with "does not accept healer completion claim" and reconcileExistingClaim re-fetches the heal-op, confirms chain ResultHash equals our manifest, and persists the dedup row so finalizer takes over. Negative-attestation hash: chain rejects empty VerificationHash even on verified=false (msg_storage_truth.go:271-273). Verifier synthesizes a deterministic non-empty placeholder (sha256("lep6:negative-attestation:"+reason) base64) on fetch_failed and hash_compute_failed paths. Chain only validates VerificationHash content for positive votes (msg_storage_truth.go:288-294), so any non-empty value is well-formed for negatives. Components added supernode/self_healing/ service.go Single tick loop; mode gate (UNSPECIFIED skips); healer dispatch; verifier dispatch; finalizer poll; sync.Map in-flight + buffered semaphores (reconstructs=2, verifications=4, publishes=2). healer.go Phase 1: submit-then-persist ordering; reconcileExistingClaim handles post-crash recovery when chain accepted a prior submit. verifier.go Phase 2: fetch from assigned healer, retry with exponential backoff (3 attempts), submit verified= false with non-empty placeholder hash on persistent fetch failure; positive-path hash compares against op.ResultHash; reconciles chain-side "verification already submitted" idempotency. finalizer.go Phase 3: VERIFIED → publish + cleanup; FAILED/ EXPIRED → cleanup only; transient states no-op. peer_client.go secureVerifierFetcher dials via the same secure-rpc / lumeraid stack the legacy storage_challenge loop uses. supernode/transport/grpc/self_healing/handler.go Streaming ServeReconstructedArtefacts RPC. DefaultCallerIdentityResolver pulls verifier identity from the secure-rpc (Lumera ALTS) handshake via pkg/reachability.GrpcRemoteIdentityAndAddr — production wiring uses this so req.VerifierAccount is never trusted alone. Authorizes caller ∈ op.VerifierSupernodeAccounts AND identity == op.HealerSupernodeAccount; refuses with FailedPrecondition when not the assigned healer and PermissionDenied for unassigned callers. 1 MiB chunks. proto/supernode/self_healing.proto SelfHealingService { ServeReconstructedArtefacts streams chunks }. Makefile gen-supernode wires it; gen/supernode/self_healing*.pb.go regenerated. supernode/cascade/reseed.go Split RecoveryReseed: PersistArtifacts=true (legacy/republish) vs PersistArtifacts=false (LEP-6 stage-only). Adds stageArtefacts + PublishStagedArtefacts. Stages reconstructed file bytes and a JSON manifest the §19 transport reads. supernode/cascade/staged.go ReadStagedHealOp helper used by the transport handler. supernode/cascade/interfaces.go CascadeTask interface gains RecoveryReseed + PublishStagedArtefacts so self_healing depends only on the factory abstraction. pkg/storage/queries/self_healing_lep6.go Tables heal_claims_submitted (PK heal_op_id) and heal_verifications_submitted (PK (heal_op_id, verifier_account)) for restart dedup. Typed sentinel errors ErrLEP6ClaimAlreadyRecorded / ErrLEP6VerificationAlreadyRecorded. Migrations wired in OpenHistoryDB. pkg/storage/queries/local.go LocalStoreInterface embeds LEP6HealQueries. supernode/config/config.go SelfHealingConfig YAML block (enabled, poll_interval_ms, max_concurrent_*, staging_dir, verifier_fetch_timeout_ms, verifier_fetch_attempts). Default disabled until activation. supernode/cmd/start.go Constructs selfHealingService.Service + selfHealingRPC.Server (with DefaultCallerIdentityResolver) when SelfHealingConfig.Enabled, registers SelfHealingService_ServiceDesc on the gRPC server, appends the runner to the lifecycle services list. Reuses cService (cascade factory) and historyStore. Tests (16 mandatory; all PASS) supernode/self_healing/service_test.go 1. TestVerifier_ReadsOpResultHashForComparison (R-bug pin) 2.

Resolved decisions applied ✓ Branch base: PR-3 tip f79f88f, NOT self-healing-improvements (single chain-driven service per Bilal direction; legacy 3-way Request/Verify/Commit RPC discarded). ✓ Verifier compares against op.ResultHash (chain msg_storage_truth.go :291). Pinned by TestVerifier_ReadsOpResultHashForComparison. ✓ Hash recipe = cascadekit.ComputeBlake3DataHashB64 (=Action.DataHash recipe). Same recipe healer + verifier + chain enforce. ✓ KAD publish AFTER chain VERIFIED (§19 healer-served-path gate); staging directory is the only authority before quorum. ✓ Finalizer mechanism: Opt 2b (per-op GetHealOp poll, folded into single tick loop) — no Tendermint WS, no monotonic-growth poll. ✓ Concurrency default: semaphore=2 reconstructs (RaptorQ RAM-aware), 4 verifications, 2 publishes. ✓ Mode gate: UNSPECIFIED skips dispatcher entirely (Service.tick early-return; verified by TestService_UnspecifiedModeSkipsEntirely). ✓ Three-layer dedup: sync.Map + bounded semaphores + SQLite (heal_claims_submitted + heal_verifications_submitted). ✓ Submit-then-persist ordering with reconcile path for crash recovery. ✓ Non-empty placeholder VerificationHash on negative attestations (chain rejects empty regardless of verified bool). ✓ Caller authentication via secure-rpc / Lumera ALTS handshake at transport layer; req.VerifierAccount never trusted alone in production.

Public surfaces added: - supernode/recheck: Candidate, RecheckResult, Finder, Attestor, Service, ReporterSource, SupernodeReporterSource, eligibility and outcome mapping helpers. - pkg/storage/queries: RecheckQueries plus SQLite-backed HasRecheckSubmission and RecordRecheckSubmission. - pkg/lumera/modules/audit: GetEpochReportsByReporter query wrapper for network-wide candidate discovery. - supernode/storage_challenge: LEP6Dispatcher.Recheck to execute RECHECK-bucket proofs without adding results to epoch reports. Spec/chain alignment decisions: - Candidate discovery is network-wide: the service lists registered supernodes and scans EpochReportsByReporter over the configured lookback window, rather than only scanning this node's own report. - Recheck candidate eligibility mirrors chain storage transcript records: only HASH_MISMATCH, TIMEOUT_OR_NO_RESPONSE, OBSERVER_QUORUM_FAIL, and INVALID_TRANSCRIPT originals are eligible. - The service rejects self-target candidates and self-reported challenged results because chain SubmitStorageRecheckEvidence rejects creator == challenged_supernode_account and creator == challenged result reporter. - Recheck execution maps local PASS to PASS and confirmed hash mismatch to RECHECK_CONFIRMED_FAIL; timeout/quorum/invalid transcript classes remain explicit and are not collapsed. - Recheck execution reuses the PR-3 compound dispatcher in RECHECK bucket mode with an isolated temporary buffer so recheck results are submitted only through MsgSubmitStorageRecheckEvidence and are never included in host epoch reports. - Local dedup is submit-then-persist keyed by epoch_id + ticket_id (creator/self is implicit locally); tx hard-fail does not persist, while chain replay/already-submitted errors persist local dedup for idempotence. - Startup/config wiring is additive under storage_challenge.lep6.recheck and remains disabled unless explicitly enabled. Tests added/updated: - Eligibility matrix for all eligible and rejected result classes. - Outcome mapping for PASS, RECHECK_CONFIRMED_FAIL, timeout, quorum, and invalid transcript. - Finder lookback/order/limit/local-dedup behavior. - Network-wide reporter discovery regression so peer-reported failures are discovered and not self-report-only. - Self-target and self-reported candidate rejection pinned against chain validation. - Service mode gate and submit path. - Attestor submit-then-persist, tx hard-fail retry safety, idempotent already-submitted handling, and required-field rejection. - SQLite recheck submission idempotence/dedup preservation. - Dispatcher RECHECK execution path integration through focused package tests.

Supernode must depend on Lumera `v1.12.0` APIs. +2. Operators must run against a Lumera chain whose audit module includes LEP-6 storage-truth endpoints. +3. Supernode local SQLite storage must be writable; PR-6 adds local idempotency state for pending/submitted heal and recheck txs. +4. Existing Supernode status/log collection should be enabled so LEP-6 snapshot counters and structured logs are visible through the same operator workflow used by storage challenge, Cascade, and supernode metrics. + +## Local validation commands + +From the supernode repository root: + +```bash +export PATH=/home/openclaw/.local/go/bin:$PATH +go test $(go list ./... | grep -v '/tests') +``` + +For the real-chain LEP-6 system test: + +```bash +make system-test-setup +make test-lep6 +``` + +`make test-lep6` runs `tests/system/TestLEP6RealChainIntegration` using the same real `lumerad`/local-chain harness as Cascade e2e. It does not use chain mocks. + +## Observability + +LEP-6 uses the repo-native Supernode observability pattern: in-process atomic snapshots plus structured `logtrace` fields. PR-6 does **not** add a LEP-6-only Prometheus endpoint. + +LEP-6 snapshot signals include: + +- challenge dispatch results by chain result class; +- challenge dispatch throttling drops by reason; +- challenge dispatch epoch duration totals/counts by role; +- ticket discovery outcomes; +- no-ticket-provider-active state; +- recheck candidates discovered and current pending candidate gauge; +- recheck submissions by result class/result; +- recheck already-submitted dedupe count; +- recheck failure counts by stage; +- heal claims by result; +- heal claim reconciliation count; +- heal verifications by result/vote; +- heal verification already-recorded dedupe count; +- self-healing pending claim gauge; +- self-healing staging bytes gauge; +- finalizer publish count; +- finalizer cleanup count by terminal chain status. + +Suggested alerts/signals from snapshots/logs: + +- sustained heal-claim `submit_error` or `stage_error` increases; +- sustained heal-verification `submit_error` or `stage_error` increases; +- sustained recheck failure increases by stage; +- challenge dispatch throttling drops approaching the chain cap; +- no-ticket-provider-active remaining true after candidate-producing epochs; +- self-healing staging bytes increasing without matching finalizer publish/cleanup progress; +- rejected/failed/expired finalizer cleanup spikes after a release. + +## Operational behavior + +### Successful healing + +1. Chain schedules a heal-op and assigns a healer/verifiers. +2. Healer stages recovered data locally and pre-stages a local dedup row. +3. Healer submits `MsgClaimHealComplete`. +4. On chain acceptance, Supernode marks the local row as submitted. +5. Verifiers fetch and verify the staged manifest/hash, pre-stage local dedup rows, and submit `MsgSubmitHealVerification`. +6. Once chain marks the heal-op verified, the finalizer publishes the healed artifact to the P2P layer. + +Important: the healed file is not published as durable P2P recovery output before successful chain verification. + +### Rejected healing + +If verifier quorum rejects the heal, the chain marks the heal-op rejected/failed according to Lumera `v1.12.0` keeper rules. Supernode does not publish the healer output as recovered data. + +### Healer cannot heal / no-show + +If the healer cannot produce a valid manifest or misses the deadline, the chain eventually expires/fails the heal-op and applies LEP-6 scoring/probation rules. Supernode records errors and retry/backoff state locally where applicable, but does not override chain status. + +### Restart/idempotency + +PR-6 closes the submit-success/persist-crash window by pre-staging local pending rows before chain tx submission for: + +- heal claims; +- heal verifications; +- recheck evidence submissions. + +Pending rows dedup retries after restart; successful txs are marked submitted after chain acceptance. Submit failures remove the pending row so the operation can retry later. + +## Troubleshooting + +- If duplicate tx errors appear after restart, inspect local SQLite `status` values for LEP-6 pending/submitted tables and compare with chain heal/recheck state. +- If recheck candidates stop processing, inspect `recheck_attempt_failures`; failures expire after the configured TTL and successful submissions clear the failure budget. +- If LEP-6 counters are flat while work is expected, inspect service startup/configuration first, then check structured `logtrace` events for the challenge, recheck, and self-healing services. +- If `make test-lep6` fails before tests start, run `make system-test-setup` and confirm `lumerad version` matches the Lumera dependency version. diff --git a/gen/supernode/service.pb.go b/gen/supernode/service.pb.go index f74c97f0..90990d10 100644 --- a/gen/supernode/service.pb.go +++ b/gen/supernode/service.pb.go @@ -1,7 +1,7 @@ // Code generated by protoc-gen-go.

Per Matee's lens — silent data-loss, chain N/R/D math fragility, operator-impact / fee-burn, DoS / bulk-exfil on authenticated handlers, English-substring chain-error matching — every finding is closed without spec divergence and with regression tests. Highlights by failure class: 1. Typed chain-error sentinels (H9 umbrella; foundation for C3/C4/C5/H1/L3) - new pkg/lumera/chainerrors with predicates (errors.Is + gRPC code + substring fallback) and transient short-circuit; replaces every strings.Contains(err.Error(), …) under self_healing/recheck/ storage_challenge. 2. Storage layer (C2, M8, M12, L3, L4) - recheck dedup migrated to (heal_op_id, target_supernode) PK with typed ErrAlreadyExists, INSERT … ON CONFLICT DO NOTHING. - PRAGMA-guarded ALTER TABLE migrations; tx-helper sequence cap and fairness; finder per-reporter error isolation. 3. Self-healing safety overhaul (C3, C4, C5, H1, H2, H7, M2, M5, M7, L2) - reconcile-not-purge for transient errors; pre-submit deadline-epoch check; paginated GetHealOpsByStatus; bounded streaming caps; per-op deadline goroutines; finalizer runs regardless of mode-gate; reseed via os.Rename / io.Copy; canonical negative-attestation reason taxonomy. 4. Storage-challenge dispatch + buffer (C2, H3, H4, H5, H6, M4, M9, M10, M11, L5) - chain-anchored partial rows for pre-derivation early returns (ctx.Err passthrough); sign errors drop the row + metric, never lie; arrival-order + (target,bucket) fairness buffer (no lex shaping); no class swap when rolled class empty (NO_ELIGIBLE_TICKET only); bounded LRU index-size cache; SQLite-persisted lastSubmittedEpoch; at-least-one-class-non-zero ticket gate; per-call recheck buffer. 5. Operator config / shutdown / probing (C1, M1, M3, M6, L6) - LEP-6 toggles default-FALSE on missing config; startup advisory WARN names each disabled service; structural validator rejects recheck=true with parents disabled; staging-dir resolved via GetFullPath; historyStore.CloseHistoryDB moved after services drain; probeTCP taxonomy distinguishes ECONNREFUSED (CLOSED) from DNS / EHOSTUNREACH / ctx.Err / Timeout (UNKNOWN); fixtures aligned with new gating chain. 6. Transport handlers (C6, H8, L1) - GetCompoundProof: per-call MaxCompoundRanges=16, per-range cap 4*LEP6CompoundRangeLenBytes, MaxCompoundAggregateBytes=16 KiB; rejected before any artifact bytes are read. - ServeReconstructedArtefacts: gated on op.Status == HealOpStatus_HEAL_OP_STATUS_HEALER_REPORTED. - NewServer rejects nil resolveCaller; NewServerForTest is the documented test-only escape hatch. Spec-fidelity: no scoring constants changed; no chain-side semantics altered. Chain-anchored validator rules cited at chain path:line for every consensus- affecting branch (PK shape, partial-row class, dispatch class fallback, deadline sentinel). Validation: go build, go vet, focused per-wave package tests, and full go test $(go list ./... | grep -v /tests) -count=1 sweep — zero regressions across 50+ packages. ---
