From e88692f685b7621a5593cae4e39fa262cda33e9f Mon Sep 17 00:00:00 2001 From: Jason Vranek Date: Thu, 30 Jul 2026 15:00:23 -0700 Subject: [PATCH 01/95] fix(helix): track latest helix-relay:main config schema + add setup runbook Reconcile the embedded helix config with current helix-relay:main: - drop the removed `network_config: !Custom {...}` block (the relay now fetches chain spec + genesis from the beacon node at startup) - migrate `cores` to the 10-field CoresConfig (drop sub_workers; add decoder, simulator, top_bid, data_gatherer, block_merging, housekeeper) Bump the ethereum-package fork to the helix wait-for-genesis fix.

ROOT CAUSE (via `docker logs` on the exited helix container, NOT the + kurtosis error): helix panics on startup — `config.rs: failed to parse config file: + network_config: untagged and internally tagged enums do not support enum input`. The public + `ghcr.io/gattaca-com/helix-relay:main` (moving tag) drifted and its config schema no longer matches the + `helix_relay_config` the pinned fork (`ethereum-package @ 4844f884`) renders. The UTF-8 grpc error is a + SECONDARY symptom of kurtosis streaming the crashing container. Reproduced on kurtosis 1.20.0 AND 1.18.1 + (NOT a kurtosis-version issue). FIX (chosen: track latest helix): reconcile the embedded + `helix_relay_config` in `scripts/generate_kurtosis_configs.py` to current `:main`. Source of truth = + the `:main` BINARY's serde metadata (`docker create` + `docker cp /app/helix-relay` + `strings`), NOT + the ws-workspace helix checkout (a divergent WS branch, unreliable). Two drifts fixed: + 1. Deleted `network_config: !Custom {dir_path, genesis_validator_root, genesis_time}` — `:main` removed + it; the relay now fetches chain spec + genesis from the beacon node at startup. + 2. `cores:` (CoresConfig) is now 10 fields: dropped `sub_workers`; added `decoder: [0]` (Vec) + + `simulator`/`top_bid`/`data_gatherer`/`block_merging`/`housekeeper` (usize `0`). The panic + mis-reported this as top-level `missing field \`decoder\`` (a `#[serde(flatten)]` artifact). + FAST iteration loop (seconds, not 10-min kurtosis runs): `docker run --rm -v cfg:/app/config.yaml + ` panics ~1s per bad field; success = it reaches the beacon-fetch stage past config parse. + PIN vs LATEST: pin via `HELIX_RELAY_IMAGE=` in `.env` (no template change). Template shape is + COUPLED to helix version, so a pinned OLD helix needs the OLD template. For both (relevant to the + WebSocket-vs-helix work), add a schema switch in the generator keyed off the image tag. Core VALUES (all + core 0) are a smoke-test choice, not a realistic perf layout. +- **kurtosis version + config-version clash:** J runs 1.18.1. A newer CLI (1.20.0) writes + `~/.config/kurtosis/kurtosis-config.yml` at `config-version: 9`, which 1.18.1 can't read + (`ConfigVersion(9) ... newer than ConfigVersion_v7`).

As ePBS clients ship, the issue rate +spikes and the human-in-the-loop version (paste terminal output, `docker logs` a container by hand, +isolate the real panic under three masking errors) does not scale. **The win is a loop an agent can +drive: launch -> triage -> diagnose -> report, autonomously.** + +## The thesis (the mechanism, not the rewrite) +The leverage is NOT "rewrite in Rust." It is three properties, in priority order: + +1. **Preflight against the real images.** Validate a rendered config by having the actual relay / + commit-boost image parse it in ~1s, before any 10-minute devnet spend. This is the generalized, + productized form of the manual `docker run --rm ` loop that found today's drift. It is + the single biggest agent-friendliness win and it retires the whole class of "schema drift discovered + 5 minutes into a launch as a masked runtime panic." +2. **Observable by default (NOT agent-only tooling — J 2026-07-30).** The goal is legibility as a system + property: structured `tracing` events on everything, a durable verdict report, and AUTOMATIC root-cause + capture on any failure, emitted as the normal output of a normal run. A human reads a pretty rendering + of that stream; an agent reads the JSON; ONE source of truth, not a separate agent surface. So + root-cause capture is a PROPERTY OF THE RUN (when a service dies, the harness attaches its container's + root panic to the event stream automatically) — the `triage` verb is only the after-the-fact entry + point into that same data, not the mechanism. Agents are the most demanding consumers of good + observability; design for observability and the agent affordance comes free. This is also strictly + better for a human (root panic inline vs `docker logs` by hand). +3. **Feature-asserting scenarios.** Every scenario positively asserts its feature's codepath FIRED + (skip-sigverify counter > 0, timing-game poll count, extra-validation RPC hit, cross-relay best-bid + comparison), not merely "the pipeline didn't crash." A scenario that passes while the feature + silently no-oped is a non-test. [[verify-treatment discipline]] + +Type-reuse from the real config crates is a supporting move (see Law 1), valuable but scoped: it makes +commit-boost config drift a compile error; it does NOT solve helix drift (Law 1 caveat). Preflight is +what covers both halves. + +## Design laws (non-negotiable; each prevents a named smell) +1. **Configs come from the real schemas, never hand-mirrored strings.** The Python string-template + generator (`generate_kurtosis_configs.py`, which reverse-engineers helix's serde layout from binary + panics) is the root smell and dies. Commit-boost config is built from `cb_common` config structs and + serialized (a renamed field is then a compile error / `deny_unknown_fields` deserialize error). + *Caveat:* helix types are NOT reusably importable (divergent branch, different org, a `teloxide` + type graph) — and helix `CoresConfig` is the field that drifts most. So helix gets an owned, thin + `HelixRelayConfig` mirror pinned in lockstep with the `HELIX_RELAY_IMAGE` tag, guarded by the + Preflight law. The ~4 kurtosis-runtime template fields (`{{ .Timestamp/.Port/.Network/.Relays }}`) + are the one place string-patching survives; isolate them. +2. **No config, image name, or scenario truth exists in two hand-edited places.** One image map (kill + the four-way `commit-boost/pbs:kurtosis` vs `commit-boost/commit-boost:kurtosis` drift). Delete the + checked-in `example-kurtosis-config.yml` (an already-stale hand-copy of generator output) in favor + of generate-on-demand. +3. **Every scenario asserts its feature fired.** No green from mere block delivery. Fix the mux + pass-gate to key on `pubkeys_verified`, not `total_events` (today it reports "all routing verified" + having verified zero decisions when CB debug logging is off). Fix the best-bid check to compare bid + values across relays, not union-by-slot (today one delivering relay passes identically to genuine + two-relay aggregation). +4. **Verdict logic is unit-tested and TDD-able without a devnet.** The checks are pure functions over + already-fetched data; inject fixture beacon/relay responses and test the math + (`chain_health`/`payload_matching`/`relay_pipeline`/`check_mux_routing` have zero decision-logic + tests today). CI runs the generator and schema-validates every output. +5. **Observability is a first-class system property, not an agent bolt-on (J 2026-07-30).** Everything + emits structured `tracing` events + a durable verdict report; failures auto-attach their root cause to + that stream. Humans and agents tap the SAME surface (pretty rendering vs JSON) — never build a separate + agent-only tool category; build good logging on everything and let both consume it. cb-verify's + `VerificationReport` is the model to extend, not replace. +6. **Dogfood the abstraction in our ONE fork; upstream is optional icing later (RATIFIED, J 2026-07-30).** + The `(relay, sidecar, builder)` component model (`mev_resolver.star`) + the `mev_type: custom` config + API ALREADY exist in our fork, and cb-testing ALREADY consumes them — so this is maturing what exists, + not a new build, and there is NO rush to upstream. Topology: ONE fork carries the abstraction; cb-testing + is its consumer/dogfood (do NOT maintain two forks — the abstraction-vs-usage seam is the + fork/consumer boundary, not two forks of one repo). "Do it properly" = (a) refine the abstraction to be + clean + GENERAL (reads like an API a stranger would use: any relay x any sidecar x any builder, already + spans epbs/buildoor/mev-rs), (b) add the external-sidecar hook (let VCs point at an externally-supplied + builder URL; make each component independently `none`-able) — the one missing piece that later enables a + thin compose-over-UNMODIFIED-upstream shim, (c) keep the fork delta minimal + PR-shaped as you touch it. + OPTIONAL LATER: upstream the proven code (a MEDIUM PR — the `mev_resolver.star` module + refactor of + `main.star`'s mev dispatch + `input_parser.star`'s per-client builder-flag matrix), then cb-testing + repoints its `import_module` from our-fork to upstream in one line. WHY a pure shim isn't possible on + TODAY's upstream: upstream injects the VC `--builder` flag inside `enrich_mev_extra_params`, triggered + only by a native `mev_type` via a naming-convention URL, with no external-builder hook — a shim would + otherwise have to reimplement the brittle 7-client flag matrix, worse than the fork. (The `#1384` "exit" + from an earlier audit is UNVERIFIED — no reference exists in the fork; check upstream HEAD before any PR.) +7. **Coverage is a matrix, not a point.** Scenarios parametrize over EL/CL client pairs. A CB regression + specific to nethermind+prysm is invisible today (everything hardcodes geth+lighthouse). + +## Architecture target +A single Rust application (`sim`) — library-first, `clap` CLI, `tracing` JSON: +`sim generate | preflight | run | verify | triage`. It shells `kurtosis` (no Rust SDK exists; enclave +ops stay text-parsing with `--format json` where available — inherent, not fixable by the rewrite). The +mature `src/` verifier (discovery/beacon/relay/metrics/checks/report) moves in nearly verbatim. Config +generation folds in from Python; orchestration folds in from `run-and-verify.sh` + `cb-orchestrator` +(one entry at `--jobs 1`); the assertoor duplicate and the shell launcher retire. Language count drops +4 -> 2 (Rust + the unavoidable starlark fork). + +**Home (RATIFIED, J 2026-07-30): stays in the cb-testing repo** — its own repo, `cb-common` pinned by +git tag to the release under test. NOT embedded as a commit-boost-client workspace crate (embedding +solves CB drift, which was not the pain — helix was, and helix types can't live in the CB workspace +anyway — while dragging kurtosis/docker/testnet weight into commit-boost's CI), and NOT a new repo. +A tag-dep expresses "test exactly this release"; recover early-CB-drift signal with a nightly lane that +builds the harness against `cb main`. + +**Rust scope (RATIFIED direction, J 2026-07-30): full Rust.** The whole harness consolidates into the +single `sim` app — generation + orchestration folded in, Python/shell/assertoor retired.

Each new CB feature ships with its sim + scenario, like a unit test. +- **P4 — fork diet + treadmill:** `upstream` remote + tagged pin; shrink overlay toward just + `mev_resolver.star`; a routine `bump` workflow (update CLI -> rebase fork -> run sweep -> diff verdicts + for regressions), agent-runnable. +- **P5 — consolidate:** fold orchestration into `sim`; retire shell/justfile/assertoor duplication. +- **Later — ePBS:** an ePBS-aware relay/builder + a gloas ethereum-package + the epbs-branch CB image; + a new `cb_get_execution_payload_bid` check arm + an envelope-flow beacon check.

A human reads a pretty rendering of that +stream; an agent reads the JSON; one source of truth. `preflight` and `triage` are just entry points into +that same observability surface (validate a config; attach to an already-broken enclave after the fact) — +not a separate agent category.

On any + launch failure the harness **auto-attaches the crashed service's root panic** to its structured output + (the `triage` capability, fired automatically — Task 4 — not a verb an operator must remember), piercing + the kurtosis-log masking via a `docker logs` fallback. `sim triage ` is the after-the-fact entry + point into that same capability. +- **Does NOT (stated plainly):** preflight does NOT catch runtime/timing panics like today's pre-genesis + `current_slot().unwrap()` (#3) — that isn't a config problem (its fix was the launcher wait-for-genesis + wrapper) and is out of preflight's universe; it surfaces only via a run + triage.

(Reframed from v1's overstated "one command for + today's saga.") + +## Scope decision (from the grill): helix-only preflight in P1 +All three of today's failures were **helix**; CB config has never drifted. The CB-via-`cb-common`-types +path is deferred to P2 because it is (a) not the measured pain, (b) broken as v1 specified — `chain`'s +`Deserialize` reads a spec file off disk (`types.rs:393`), `{{ range .Relays }}` is a Go loop not a var, +so "substitute dummies then `toml::from_str`" fails on a *valid* config — and (c) a 409-crate dep +(alloy-full + lighthouse-from-git + blst/kzg C builds).

Mon Sep 17 00:00:00 2001 From: Jason Vranek Date: Thu, 30 Jul 2026 21:11:34 -0700 Subject: [PATCH 03/95] style(clippy): clear pre-existing warnings so CI can enforce -D warnings Mechanical clippy fixes across the pre-sim code (collapsible_if -> let-chains, while_let_loop -> for/by_ref, manual_strip -> strip_prefix, unnecessary_unwrap, useless_format/vec, needless_borrow, expect_fun_call). No behavior change; 77 tests still green. Two justified #[allow]s (with comments): too_many_arguments on the enclave pipeline launcher (an options struct would read worse), and dead_code on two relay data-API Deserialize targets whose unread fields document the wire schema. `cargo clippy --all-targets -- -D warnings` now passes clean, so every subsequent commit builds under a real warning gate. --- src/bin/test_mux.rs | 47 ++++++++++---------- src/bin/test_relay.rs | 6 +++ src/checks/mux_routing.rs | 83 +++++++++++++++++------------------- src/checks/relay_pipeline.rs | 11 +++-- src/orchestrator.rs | 38 ++++++++--------- 5 files changed, 93 insertions(+), 92 deletions(-) diff --git a/src/bin/test_mux.rs b/src/bin/test_mux.rs index e22120d..12e24cb 100644 --- a/src/bin/test_mux.rs +++ b/src/bin/test_mux.rs @@ -159,16 +159,16 @@ fn main() { for entry in &entries { if entry.validator_pubkeys.iter().any(|e| e.to_lowercase() == pk_norm) { checked += 1;

There is no duplication for typing to kill. +- **Typed helix buys no guard.** Helix types are not importable (divergent org/branch), so a mirror is NOT + checked against helix — it's hand-guessed from binary panics either way (North Star Law 1 caveat says so + outright). Preflight stays the only reality check, exactly as with a string. Typing also thins the ~40 + lines of hard-won drift comments (the `network_config` removal, the binary-verified 10-field `CoresConfig`) + that ARE the expensive knowledge. +- **The serde mechanism is fragile.** serde_yaml has no unquoted-scalar emit hook, so runtime holes like + `port: {{ .POSTGRES_PORT }}` (unquoted) force a "serialize a sentinel number, then string-replace it" + dance. Sentinels collide: `2000` collides with `late_in_slot_time_ms = 2000`; `db_name` and `user` are + both `"helix"` so one value can't map to two placeholders; `instance_id` contains the substring `helix`. + All silent-corruption traps — introduced solely by choosing serde structs. +- **"Just emit concrete values, no templating" is refuted by the code.** `run-and-verify.sh` feeds the file + straight to `kurtosis run --args-file`; the ethereum-package fork is the template renderer — + `mev_boost_launcher.star` and `helix_relay_launcher.star` call `plan.render_templates(..., {Timestamp, + Port, Relays, POSTGRES_HOST_NAME, BEACON_URI, BLOCKSIM_URI, ...})` with **runtime service-discovery + values that do not exist until kurtosis is running.** The `{{ }}` MUST survive into the checked-in file. + +**Conclusion:** port the templates verbatim into Rust `const` strings (the `{{ }}` runtime holes stay as +literal text — no serialization, so the entire sentinel/quoting hazard evaporates), and put the typing only +where it pays: a `Scenario` enum + one `Images` map for assembly.

Today the green run only works because a `.env` +override masks the wrong default. The unified `Images` map bakes the correct value as the default. + +## Mechanism (what the code does) +- **helix block:** one `pub const HELIX_RELAY_CONFIG: &str` — a verbatim port of the Python + `build_helix_relay_config()` output, **comments preserved**. Contains literal `{{ .POSTGRES_* }}`, + `{{ .BEACON_URI }}`, `{{ .BLOCKSIM_URI }}`. No variation across scenarios (proven), so it's a plain const. +- **CB block:** a `cb_toml(params) -> String` that reproduces `build_cb_toml_basic` — a base template with + Rust-side injection of the generate-time knobs (timeouts, `extra_pbs_lines`, `per_relay_lines`) and the + literal `chain = { genesis_time_secs = {{ .Timestamp }}, path = "{{ .Network }}" }`, `port = {{ .Port }}`, + and `{{ range $index, $relay := .Relays }} … {{- end }}` loop as literal text. A separate `cb_toml_mux` + reproduces `build_cb_toml_mux` (two `[[mux]]` blocks + per-node `validator_pubkeys` lists loaded from + `keys/node-{0,1}-pubkeys.json`). Generate-time injection is plain string building — NOT serde — so no + quoting/sentinel issues. +- **assembly:** a `Scenario` enum (the 6 variants) with `fn args_file(&self, images: &Images) -> String` + that joins the shared static fragments (`participants`, `additional_services`, `network_params` — kept as + vetted `const` strings; they never drifted and are out of Law 1's scope) + `mev_type: custom` + the + `mev_params` wrapper embedding the helix const and the CB string as the two `|` block scalars. +- **`Images` struct:** the ONE image map (helix/mev_relay/mev_boost/builder_el/builder_cl), correct defaults, + `.env` overrides applied at the CLI boundary (`generate::run`), NOT inside the pure assembly. + +## Acceptance (simple + strong): byte-identity to the golden +Because this is a verbatim port, `sim generate ` output is **byte-identical** to the Python +golden (modulo image values, which we bake).

The config bodies are verbatim const/string templates (helix keeps its ~40 lines of binary-verified drift comments; the {{ }} runtime holes stay literal — the ethereum-package fills them at launch). Typing lives only at the assembly layer: a Scenario enum + one Images map with the CORRECT commit-boost/commit-boost default (fixing the live-wrong commit-boost/pbs Python default). All 6 scenarios reproduce their golden fixtures byte-for-byte (the acceptance oracle); cb-basic still passes sim preflight against the real helix image. Review fixes folded in (adversarial review before commit): - load_pubkeys returns Result; run assembles ALL bodies before writing any, so a missing/malformed mux keys file fails cleanly with nothing written (matches the Python's pre-write all-or-nothing), instead of panicking mid-generation with 5 stale files left behind. - run_in(keys_dir, env_path) injectable core for hermetic negative-path tests. - Scenario::ALL reordered to the true Python emission order; misleading generate_all_matches_goldens renamed to reflect it checks IO faithfulness (the hermetic golden match lives in scenario.rs on default images). 43 sim tests green (incl. missing-keys → clean-error + atomicity); clippy -D clean. --- src/bin/sim/cli.rs | 9 + src/bin/sim/generate.rs | 147 +++++++++++++ src/bin/sim/genmodel/cb.rs | 222 +++++++++++++++++++ src/bin/sim/genmodel/helix.rs | 114 ++++++++++ src/bin/sim/genmodel/mod.rs | 34 +++ src/bin/sim/genmodel/scenario.rs | 352 +++++++++++++++++++++++++++++++ src/bin/sim/main.rs | 11 + 7 files changed, 889 insertions(+) create mode 100644 src/bin/sim/generate.rs create mode 100644 src/bin/sim/genmodel/cb.rs create mode 100644 src/bin/sim/genmodel/helix.rs create mode 100644 src/bin/sim/genmodel/scenario.rs diff --git a/src/bin/sim/cli.rs b/src/bin/sim/cli.rs index 1a40c87..99509eb 100644 --- a/src/bin/sim/cli.rs +++ b/src/bin/sim/cli.rs @@ -40,4 +40,13 @@ pub enum Command { /// Name of the kurtosis enclave to triage. enclave: String, }, + /// Generate Kurtosis args-files for the CB test scenarios (Rust port of the + /// retired `generate_kurtosis_configs.py`). + Generate { + /// Scenario name (e.g. `cb-basic`); omit to generate all six. + scenario: Option, + /// Directory to write the generated `.yml` files into. + #[arg(long, default_value = "configs/generated")] + out_dir: PathBuf, + }, } diff --git a/src/bin/sim/generate.rs b/src/bin/sim/generate.rs new file mode 100644 index 0000000..fee2a2d --- /dev/null +++ b/src/bin/sim/generate.rs @@ -0,0 +1,147 @@ +//! `sim generate` — write Kurtosis args-files for the CB test scenarios. +//! +//!

So the Law 3 fix +(no false greens) and the Law 4 fix (unit-test the verdict math) are the SAME move: **extract the pure +classifier, then test + correct it.** + +## The three confirmed false-greens (code-verified) +1. **`mux_routing.rs:678` — passes having verified zero routing decisions.** The pass branch fires whenever + `violations.is_empty()`, and the message counts `total_events` (raw log lines). If CB debug logging is + off, there are log events but zero parseable routing decisions (`pubkeys_verified == 0`), and it reports + "All N mux routing decisions verified ✓" — N being log lines, not verified decisions. Only + `total_events == 0` is guarded (→ WARN); `events>0, pubkeys_verified==0` falls through to PASS. +2. **`relay_pipeline.rs:51` — best-bid is a first-wins union by slot.** `by_slot.entry(slot).or_insert(...)` + counts DISTINCT delivered slots; it never compares bid VALUES across relays. One delivering relay scores + identically to genuine two-relay aggregation — the "aggregated bidding" the multi-relay scenario exists + to test is never actually checked. +3. **`payload_matching.rs:22` — first-wins union by slot drops relay disagreement.** + `by_slot.entry(p.slot).or_insert(p.block_hash)` keeps only the FIRST relay's hash per slot, so when two + relays report different `block_hash` for the same slot (relay equivocation — the exact misbehavior this + cross-check exists to catch), all but the first are discarded before the on-chain compare. Verdict is + **order-dependent**: honest relay first → PASS (false green); bad relay first → the honest hash is + dropped. Happy path is unaffected (a slot's winning relay is unique and agrees), so it bites precisely in + the adversarial multi-relay case. (Also noted while here: `missed` — relay delivered a slot with no + on-chain block — is counted but never downgrades the verdict; and a mismatch is WARN, not FAIL.) + +## Judgment calls for J (each changes what real runs report) +- **mux.routing (Tier-1):** when routing is unverifiable (CB debug logging off → `pubkeys_verified==0`), + should it WARN or FAIL? WARN is honest ("couldn't verify") but if mux.routing stays Tier-1-must-pass, a + WARN could fail runs that pass today. Options: (a) require CB debug logging on for mux scenarios (make it a + precondition), (b) WARN + drop mux.routing from Tier-1 to "should", (c) FAIL and treat debug-logging-on as + mandatory. Needs your call. +- **payload_matching:** compare per-(relay, slot) instead of collapsing by slot; a cross-relay hash + disagreement should FAIL (or at least WARN loudly) naming the slot + the divergent relays. Confirm the + desired severity. Also: should a delivered-but-not-on-chain slot (`missed>0`) affect the verdict? +- **relay_pipeline best-bid:** define what "aggregated bidding verified" means — compare bid values across + relays per slot and assert the delivered payload matches the max-value bid? This is the most design-heavy + of the three; may want its own brief. + +## Proposed approach (TDD, mirrors the healthy `cb_metrics.rs` pattern) +For each check, in order (mux, payload, relay_pipeline): +1. **Extract the pure classifier** from the async fetch fn: `classify_(already_fetched_data) -> + CheckResult`. No behavior change in the extraction commit — the fetch fn calls the new pure fn; existing + e2e behavior identical. (This is the ONLY safe-to-preview step; do it first, review, confirm green.) +2. **RED test** encoding the CORRECT contract (the false-green case asserts WARN/FAIL, not PASS). +3. **Fix** the classifier (pubkeys_verified gate / per-(relay,slot) compare / cross-relay value compare) to + GREEN. +4. Full regression + a note in the run's report so the new WARN/FAIL is legible. + +Each check is an independent slice; land + review one before the next.

The branch now passes check + test + clippy + fmt-check. --- src/bin/sim/diagnose.rs | 3 +- src/bin/sim/generate.rs | 42 ++++++++--- src/bin/sim/genmodel/mod.rs | 5 +- src/bin/sim/genmodel/scenario.rs | 10 ++- src/bin/sim/main.rs | 8 +- src/bin/sim/preflight.rs | 62 ++++++++++++---- src/bin/sim/render.rs | 10 ++- src/bin/sim/triage.rs | 15 +++- src/bin/test_mux.rs | 114 ++++++++++++++++++++++------- src/bin/test_relay.rs | 105 ++++++++++++++++++++------ src/checks/chain_health.rs | 5 +- src/checks/mux_routing.rs | 122 ++++++++++++++++++++----------- src/checks/relay_pipeline.rs | 75 +++++++++++-------- src/discovery.rs | 5 +- src/main.rs | 60 +++++++++++---- src/orchestrator.rs | 101 +++++++++++++++---------- src/relay.rs | 8 +- src/report.rs | 6 +- 18 files changed, 529 insertions(+), 227 deletions(-) diff --git a/src/bin/sim/diagnose.rs b/src/bin/sim/diagnose.rs index d79cb11..811a23f 100644 --- a/src/bin/sim/diagnose.rs +++ b/src/bin/sim/diagnose.rs @@ -227,7 +227,8 @@ fn log_tail(lines: &[&str]) -> String { mod tests { use super::*; - const SERDE_MISSING: &str = include_str!("../../../tests/fixtures/helix_serde_missing_field.log"); + const SERDE_MISSING: &str = + include_str!("../../../tests/fixtures/helix_serde_missing_field.log"); const PREGENESIS: &str = include_str!("../../../tests/fixtures/helix_pregenesis_unwrap.log"); const INVENTED: &str = include_str!("../../../tests/fixtures/invented_field.log"); const MULTI_MASKED: &str = include_str!("../../../tests/fixtures/multi_masked.log"); diff --git a/src/bin/sim/generate.rs b/src/bin/sim/generate.rs index 3774dd5..157e1ca 100644 --- a/src/bin/sim/generate.rs +++ b/src/bin/sim/generate.rs @@ -9,7 +9,7 @@ use std::fs; use std::path::Path; -use eyre::{eyre, Result, WrapErr}; +use eyre::{Result, WrapErr, eyre}; use crate::genmodel::scenario::{Images, Scenario}; @@ -47,7 +47,12 @@ pub fn check(scenario: Option<&str>, out_dir: &Path) -> Result<()> { check_in(scenario, out_dir, Path::new("keys"), Path::new(".env")) } -fn check_in(scenario: Option<&str>, out_dir: &Path, keys_dir: &Path, env_path: &Path) -> Result<()> { +fn check_in( + scenario: Option<&str>, + out_dir: &Path, + keys_dir: &Path, + env_path: &Path, +) -> Result<()> { let images = images_from_env(env_path); let outputs = assemble(scenario, &images, keys_dir)?; @@ -75,10 +80,16 @@ fn check_in(scenario: Option<&str>, out_dir: &Path, keys_dir: &Path, env_path: & /// Select scenarios and assemble each `(name, body)`.

The ~11-slot sampling also made the "no competition" WARN the default even when aggregation works. The pure classify_best_bid verdict logic was sound; only the IO source was wrong. Correct design (P3 follow-up): source per-relay bids from the CB "received new header" log events (relay_id + slot + value_eth, already parsed by parse_cb_log_line, full-coverage not sampled), parse value_eth decimal->wei for Ord, and compare the delivered value to the max OFFERED bid per slot. That needs CB-log context (enclave + cb_service_names) plumbed into the check — a focused, separately-reviewed piece rather than a rushed trust-core patch. check_payloads_delivered_multi stays as the coverage check. mux.routing and payload_hash_match fixes are unaffected. --- src/checks/relay_pipeline.rs | 200 +---------------------------------- 1 file changed, 1 insertion(+), 199 deletions(-) diff --git a/src/checks/relay_pipeline.rs b/src/checks/relay_pipeline.rs index aa8b422..39f21e7 100644 --- a/src/checks/relay_pipeline.rs +++ b/src/checks/relay_pipeline.rs @@ -1,8 +1,6 @@ //!

The +bodies are ported **verbatim** from the retired Python `generate_kurtosis_configs.py` into `const` +strings / string builders — the P2 grill killed the "build from `cb_common` structs / typed helix +mirror" plan (helix types aren't importable; the serde-sentinel mechanism was fragile; the templates +weren't actually duplicated).

A separate test guards the tracked +`configs/generated/cb-basic.yml` (which `render.rs` and `sim preflight` consume as a fixture) against +silently drifting from the generator. `sim generate --check` is the CI/agent form of the same guard. + +The one image map (`Images::default()`) is also where the historical four-way +`commit-boost/pbs` vs `commit-boost/commit-boost` drift was killed; `.env` overrides are applied only +at the CLI boundary (`generate::run`), keeping assembly pure and hermetically testable. + +--- + +## 5. The verdict model + +Checks are pure functions over already-fetched data; each returns a `CheckResult { name, tier, status, +detail }` where `status ∈ {Pass, Fail, Warn, Skip}` and `tier ∈ {1, 2, 3}`. `cb-verify` collects every +check into `Vec`, then the report verdict is: **`Fail` iff any Tier-1 check is `Fail`, +else `Pass`.** `report::exit_code` computes the process code by filtering to `tier == 1` checks: +**no tier-1 check present → 2** (nothing gating ran — a setup/infra failure; the discovery/preflight/ +timeout paths in `main.rs` also `return 2` directly), **any tier-1 `Fail` → 1**, **else → 0**. +Tier-2/Tier-3 `Fail`s and all `Warn`s are **non-fatal** +by design; `--strict` promotes selected soft warnings to `Fail`. `Skip` never fails the run (a check +skips when its inputs are unavailable — e.g. no metrics port, no validator pubkeys, no `[[mux]]` +sections). + +`sim preflight` has its own narrower 3-valued verdict (`Pass` / `Fail{field}` / `Inconclusive`) and +only its `Fail` aborts a launch — an `Inconclusive` (slow pull, docker down, pre-genesis panic) must +never be scored as config drift. + +The per-check catalog (names, tiers, thresholds, what each asserts) lives in **`docs/CHECKS.md`**. + +--- + +## 6. Key architectural decisions + rationale + +- **Shell out to kurtosis, synchronously, and parse text.** There is **no Kurtosis Rust SDK** + (`discovery.rs` TODO; only a Go SDK exists), so enclave ops are `std::process::Command` + + text-parsing — inherent, not fixable by the rewrite. And kurtosis 1.18.1 has **no `--format json`** + for the tables we read, so `discovery`/`triage` parse the human `enclave inspect` output column by + column (`split_on_multi_space`). The `sim` app is deliberately **sync / no-tokio** to match this + (verbs shell out and block; a bounded `timeout` coreutil supplies the wall-clock cap that sync std + lacks). `cb-verify` and `cb-orchestrator` *are* tokio (they do concurrent HTTP polling / parallel + enclaves), but `sim` and the shared discovery layer are not. + +- **The forked `ethereum-package` exists on purpose.** Upstream treats out-of-protocol block building + as bespoke, hard-coded convenience and injects the VC `--builder` flag deep inside + `enrich_mev_extra_params` via a naming-convention URL, with no external-builder hook. The fork carries + a general `(relay, sidecar, builder)` component model (`mev_resolver.star`) + a `mev_type: custom` + config API — which is exactly what lets a config say "helix relay + commit-boost sidecar + + reth-rbuilder builder" and, later, swap in an ePBS builder. A pure shim over today's upstream would + have to reimplement a brittle 7-client flag matrix — worse than the fork. cb-testing is the fork's + consumer/dogfood (NORTH-STAR Law 6). ONE fork; do not maintain two. + +- **The pure `classify_*` / pure-core seam.** Every verb that makes a judgement splits into a **pure + classifier** (data in, verdict out — unit-testable against fixture logs, no devnet, no docker) and a + thin **process-I/O shell** (smoke-checked by hand with the real tools). Named seams: + `preflight::classify_helix_probe`, `triage::{parse_service_statuses, services_to_triage}`, + `diagnose::extract_root_cause`, `payload_matching::classify_payload_matches`, + `best_bid::classify_best_bid` (+ `value_eth_to_wei`), `mux_routing::classify_mux_routing` (+ + `parse_cb_log_line`, `extract_mux_from_config`), `cb_metrics::{collect_endpoint_stats, + classify_endpoint, check_v2_fallback, check_relay_latency, histogram_quantile}`, and + `live::compute_deltas`. These pure cores (generic over the hash/value type, taking pre-fetched + `BTreeMap`s) are the unit-tested surface; the fixtures under `tests/fixtures/` are the real test + inputs. This is NORTH-STAR Law 4 ("verdict logic is TDD-able without a devnet").

Each now WARNs instead of passing-on-nothing: + +- **`mux.routing`** — the old pass-gate keyed on `total_events` (raw log lines) and PASSed whenever + there were no violations, even with **zero** parseable routing decisions (CB debug logging off). It + reported "all N routing decisions verified" where N was log lines, not decisions. Fixed to gate on + `routing_decisions_verified`; zero verified → WARN, and debug logging is required for mux scenarios. +- **`payload_hash_match`** — the old code was a first-wins union by slot + (`by_slot.entry(slot).or_insert(hash)`) that kept only the first relay's hash and **dropped + cross-relay disagreement** before the on-chain compare, making the verdict order-dependent (honest + relay first → false PASS). Fixed to keep every (relay, slot) hash and detect divergence → WARN, + naming the slot and relays. +- **`relay.best_bid`** — the old check was a first-wins union that counted distinct delivered slots + and never compared bid **values** across relays, so one delivering relay scored identically to + genuine two-relay aggregation. A first rewrite sourced offered bids from + `get_builder_blocks_received`, but adversarial review found that source unsound (it includes builder + submissions that failed simulation and were never offered to the proposer — a false alarm on correct + runs), so it was backed out. The shipped version sources offered bids from CB's `received new + header` log events (what CB actually compared) and WARNs whenever aggregation was not exercised or no + competitive slot could be verified, rather than PASS. + +All three land as `WARN`, which per the verdict model is **non-fatal** — see the consumer caveat in +the intro. + +## Known gaps and caveats (factual, from the code) + +- **Feature scenarios with no feature-fired assertion (Law 3 gap).** North-Star Law 3 wants every + scenario to positively assert its feature's codepath fired. Only `mux.routing` (routing decisions) + and `relay.best_bid` (cross-relay bid comparison) currently do. The `skip-sigverify`, + `extra-validation`, and `timing-games` scenarios run only the generic checks above — there is **no + check that asserts those features fired** (e.g. a skip-sigverify counter > 0, a timing-game poll + count, an extra-validation RPC hit). Such a scenario can pass while the feature silently no-oped. +- **`relay.best_bid` is inert or degenerate in common setups.** It SKIPs any single-relay run (no + aggregation to verify), and in mux mode — where each mux typically points a validator at exactly one + relay — no slot sees ≥2 relays competing, so it WARNs "aggregation not exercised" rather than + verifying anything. With an identical two-relay setup (e.g. two helix instances serving the same + bid) the comparison is technically competitive but degenerate. +- **The `cb_*_matrix` checks FAIL on any cumulative 5xx, including warmup.** The counters are + cumulative over the container's life, and a relay-side 5xx at any point in the run yields a matrix + FAIL — which then escalates to tier 1 and fails the whole run — even if the 5xx was a transient + startup/warmup blip before the observation window. There is no windowing of the counter. +- **A real anomaly can still exit 0.** As stated in the intro: relay equivocation, unverifiable + routing, and best-bid shortfall are all `WARN`. Gate on the JSON `result` per check, not the exit + code, if you care about these. +- **Metrics are usually absent.** The default kurtosis PBS mode does not configure CB metrics, so the + six Prometheus-based checks SKIP unless metrics are explicitly enabled. +- **`payload_hash_match` leniency (left as-is under P3 scope).** A delivered-but-not-on-chain slot + (`missed`) is indistinguishable from a transient beacon error and never downgrades the verdict; a + hash mismatch is WARN, not FAIL. + + diff --git a/docs/SWEEP-BACKLOG.md b/docs/SWEEP-BACKLOG.md new file mode 100644 index 0000000..7c7338a --- /dev/null +++ b/docs/SWEEP-BACKLOG.md @@ -0,0 +1,131 @@ +# Sweep backlog — 2026-08-01 + +Synthesis of a six-lens exhaustive sweep (docs, refactoring, performance, test-coverage, feature-roadmap, +correctness) of the cb-testing harness after the P1/P2/P3 + 2-helix work landed.

How to add a CHECK + +A check is a pure verdict over already-fetched pipeline data. The pattern (North-Star **Law 4** — "verdict +logic is TDD-able without a devnet"; the P3 plan calls it the `classify_*` seam): + +### The two-part shape + +**(a) Write the pure classifier — the seam.** A free function that takes *already-fetched* data (maps, +counts, parsed log events — never a network client) and returns a `CheckResult`: + +```rust +pub fn classify_(data: &AlreadyFetched) -> CheckResult { … } +``` + +`CheckResult` and its constructors live in [`src/checks/mod.rs`](../src/checks/mod.rs): +`CheckResult::{pass, fail, warn, skip}(id, tier, detail)` plus `.with_data(json)`. `id` is the check's stable +name (also its key in the JSON report), `tier ∈ {1,2,3}` (§ tier choice below), `detail` is a human string, +`data` is a `serde_json::Value` for machine consumers. `CheckStatus` serializes UPPERCASE under the JSON key +`result` (`PASS`/`FAIL`/`WARN`/`SKIP`). + +Make the classifier generic over the value type where it helps testing — e.g. +`classify_payload_matches` takes `BTreeMap>` so tests pass a trivial `u64` in place +of a real `B256` hash. + +**(b) Unit-test both sides of every boundary.** For each Pass/Warn/Fail/Skip transition, write a test with +fixture data that lands just inside and just outside the boundary. The worked example +[`src/checks/payload_matching.rs`](../src/checks/payload_matching.rs) tests: clean single-relay match → PASS, +cross-relay conflict → WARN, no-relay-matches-chain → WARN, missed-not-downgraded → PASS, empty → SKIP. Build +the fixture maps with small helpers (`by_slot(...)`, `chain(...)`) so each test is one line of intent. + +**(c) Write the thin async fetch shell.** A separate `async fn` that does the I/O (calls `BeaconClient` / +`RelayClient` / metrics / `kurtosis logs`), assembles the same data shape, and calls the classifier. It holds +**no verdict logic** — it just gathers and delegates. In `payload_matching.rs` that is +`check_payload_hash_match(...)`: fetch per-(relay,slot) hashes + on-chain hashes, then `classify_payload_matches(...)`. + +**(d) Wire it into `run_verification`.** In [`src/main.rs`](../src/main.rs) (~lines 414-526) the checks are +collected into one `Vec`. Add your fetch fn there, either via a module `run_*` that returns +`Vec` (`all_checks.extend(...)`, as chain_health / relay_pipeline / payload_matching / +cb_metrics do) or a single `all_checks.push(...)` (as best_bid and mux_routing do). Register the module in +`src/checks/mod.rs` if it is new. + +### Worked examples (read these, don't invent a new shape) + +- **[`src/checks/cb_metrics.rs`](../src/checks/cb_metrics.rs)** — `collect_endpoint_stats(scrape, endpoint) → + EndpointStats` (pure gather over parsed Prometheus) then `classify_endpoint(endpoint, &stats, strict) → + CheckResult` (pure verdict, ~19 decision tests, no known false-greens). The cleanest seam in the repo. +- **[`src/checks/mux_routing.rs`](../src/checks/mux_routing.rs)** — `parse_cb_log_line` + + `extract_mux_from_config` + `classify_mux_routing` (pure); the async shell fetches CB logs. +- **[`src/checks/best_bid.rs`](../src/checks/best_bid.rs)** — `classify_best_bid` (+ `value_eth_to_wei`), + fed by offered bids parsed from CB's own getHeader log events. + +### Pick the tier deliberately + +The tier is the **severity contract** — it decides whether your check can fail the run (full table: +[`docs/CHECKS.md`](CHECKS.md)): + +- **Tier 1 = must** — a real pipeline invariant. A tier-1 `FAIL` fails the whole run (exit code 1). Use only + for "the pipeline is genuinely broken." +- **Tier 2 = should** — a health signal. Never fails the run on its own. (`cb_metrics` matrix checks are the + one exception: authored tier 2 but *escalated to tier 1 on FAIL* because a relay 5xx is a real failure.) +- **Tier 3 = informational** — annotative only. + +Note the trust rule: a check that exists to *catch an anomaly* should prefer **WARN**, not a silent PASS, +when it could not actually verify anything (the P3 false-green fixes: `mux.routing`, `payload_hash_match`, +`relay.best_bid` all WARN rather than pass-on-nothing). WARN is non-fatal, so surface it in `data` and let the +consumer gate on the JSON `result` (§4). + +### The anti-pattern (why the seam is non-negotiable) + +**Do not weld the verdict into the async fetch fn.** `chain_health` and `relay_pipeline` inline their verdicts +in the async check fns and have *no* factored-out classifier — which is exactly the standing gap the P3 plan +([`docs/plans/P3-check-trustworthiness.md`](plans/P3-check-trustworthiness.md)) exists to close. A verdict +tangled with `await` calls cannot be unit-tested without a devnet, so its pass/fail boundaries go unproven — +which is how false-greens ship. Pure classifier first, thin I/O shell second, always. + +--- + +## 3. How to add a SCENARIO + +A scenario is a typed devnet configuration that assembles into a Kurtosis args-file. Everything lives under +[`src/bin/sim/genmodel/`](../src/bin/sim/genmodel/); the assembly is pure and guarded by byte-identity golden +fixtures. The config↔fork coupling (the two `|` block scalars, the runtime template holes) is explained in +[`docs/ARCH.md`](ARCH.md) §4 — read it before touching the block bodies. + +### Steps + +1. **Add the variant** to the `Scenario` enum in + [`src/bin/sim/genmodel/scenario.rs`](../src/bin/sim/genmodel/scenario.rs), and add it to `Scenario::ALL` + (order = emission order — match the intent; the array is what `sim generate` iterates). +2. **Fill the match arms** for the new variant: `name()` (the canonical basename, e.g. `cb-myfeature`), + `comment()` (the leading doc block), `relays()` (`&["helix"]` single-relay vs `&["helix", "helix"]` + multi-relay — this also toggles the scalar-vs-list `mev_relay` form and `mev_relay_image` emission), + `cb_block()` (the CB TOML — see next step), and `network_params()` (only if you need a different validator + count; `Mux` is the sole scenario using `MUX_NETWORK_PARAMS` = 256 keys). +3. **Build the CB TOML.** Most scenarios just construct a `CbParams` in `cb_block()` and call + `cb_toml(¶ms)` — the knobs are `timeout_get_header_ms`, `timeout_get_payload_ms`, `extra_pbs_lines` + (injected into `[pbs]`), `per_relay_lines` (injected inside the `{{ range }}` relay loop).

From 88ea1e005b728fac2969fe22d93dff5b4a4061c4 Mon Sep 17 00:00:00 2001 From: Jason Vranek Date: Sat, 1 Aug 2026 21:53:18 -0700 Subject: [PATCH 38/95] perf: thin-LTO + parallelize serial beacon loops + parsed-port precedence MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit No verdict/logic change — only how fast data is gathered: - Cargo.toml: lto=true → "thin" (fat LTO buys nothing at runtime for an I/O-bound binary but added 30-90s to every --release relink); tokio "full" → the used feature set; futures added as a direct dep. - The 3 serial per-slot beacon loops (check_mev_delivery_rate, check_missed_slots, check_payload_hash_match) now fetch with buffer_unordered(16) — ~2s → ~0.2s each. Folds are order-independent (commutative counters / slot-keyed maps), so the CheckResult is byte-identical; classifiers untouched. - discovery: try the already-parsed port before spawning a `kurtosis port print` subprocess per port (fallback preserved) — removes ~20-40 startup subprocesses. (check_cb_running's second inspect kept: its check-time freshness is load-bearing — reusing startup liveness would false-green a CB that dies mid-run.) --- Cargo.lock | 120 ++++++++++++++++++--------------- Cargo.toml | 5 +- src/checks/chain_health.rs | 15 ++++- src/checks/payload_matching.rs | 16 ++++- src/checks/relay_pipeline.rs | 15 ++++- src/discovery.rs | 37 +++++----- 6 files changed, 127 insertions(+), 81 deletions(-) diff --git a/Cargo.lock b/Cargo.lock index 0f88ea9..e0f78b7 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -680,6 +680,7 @@ dependencies = [ "color-eyre", "colored", "eyre", + "futures", "prometheus-parse", "reqwest", "serde", @@ -1223,35 +1224,90 @@ version = "2.0.0" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "e6d5a32815ae3f33302d95fdcb2ce17862f8c65363dcfd29360480ba1001fc9c" +[[package]] +name = "futures" +version = "0.3.33" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "a88cf1f829d945f548cf8fec32c61b1f202b6d93b45848602fc02af4b12ad218" +dependencies = [ + "futures-channel", + "futures-core", + "futures-executor", + "futures-io", + "futures-sink", + "futures-task", + "futures-util", +] + [[package]] name = "futures-channel" -version = "0.3.32" +version = "0.3.33" source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "07bbe89c50d7a535e539b8c17bc0b49bdb77747034daa8087407d655f3f7cc1d" +checksum = "262590f4fe6afeb0bc83be1daa64e52657fe185690a958af7f3ad0e92085c5ae" dependencies = [ "futures-core", + "futures-sink", ] [[package]] name = "futures-core" -version = "0.3.32" +version = "0.3.33" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "2cd50c473c80f6d7c3670a752354b8e569b1a7cbfdc0419ec88e5edad85e0dc7" + +[[package]] +name = "futures-executor" +version = "0.3.33" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "6754879cc9f2c66f88c6e5c35344bb0bdb0708b0352b1201815667c7eabc7458" +dependencies = [ + "futures-core", + "futures-task", + "futures-util", +] + +[[package]] +name = "futures-io" +version = "0.3.33" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "4577ecaa3c4f96589d473f679a71b596316f6641bc350038b962a5daf0085d7a" + +[[package]] +name = "futures-macro" +version = "0.3.33" +source = "registry+https://github.com/rust-lang/crates.io-index" +checksum = "2d6d3cde68c518367be28956066ddfef33813991b77a55005a69dae04bf3b10b" +dependencies = [ + "proc-macro2", + "quote", + "syn 2.0.117", +] + +[[package]] +name = "futures-sink" +version = "0.3.33" source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "7e3450815272ef58cec6d564423f6e755e25379b217b0bc688e295ba24df6b1d" +checksum = "e34418ac499d6305c2fb5ad0ed2f6ac998c5f8ca209b4510f7f94242c647e307" [[package]] name = "futures-task" -version = "0.3.32" +version = "0.3.33" source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "037711b3d59c33004d3856fbdc83b99d4ff37a24768fa1be9ce3538a1cde4393" +checksum = "b231ed28831efb4a61a08580c4bc233ec56bc009f4cd8f52da2c3cb97df0c109" [[package]] name = "futures-util" -version = "0.3.32" +version = "0.3.33" source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "389ca41296e6190b48053de0321d02a77f32f8a5d2461dd38762c0593805c6d6" +checksum = "a77a90a256fce34da66415271e30f94ee91c57b04b8a2c042d9cf3220179deaa" dependencies = [ + "futures-channel", "futures-core", + "futures-io", + "futures-macro", + "futures-sink", "futures-task", + "memchr", "pin-project-lite", "slab", ] @@ -1803,15 +1859,6 @@ version = "0.8.2" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "92daf443525c4cce67b150400bc2316076100ce0b3686209eb8cf3c31612e6f0" -[[package]] -name = "lock_api" -version = "0.4.14" -source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "224399e74b87b5f3557511d98dff8b14089b3dadafcab6bb93eab67d3aace965" -dependencies = [ -

Pure classify(&Probes)->Report split from the IO gather layer; only kurtosis+docker are hard-fail, the rest advisory. 14 new tests (sim bin 45 -> 59). --- src/bin/sim/checks_catalog.rs | 344 ++++++++++++++++++++++++ src/bin/sim/cli.rs | 13 + src/bin/sim/doctor.rs | 490 ++++++++++++++++++++++++++++++++++ src/bin/sim/main.rs | 24 ++ 4 files changed, 871 insertions(+) create mode 100644 src/bin/sim/checks_catalog.rs create mode 100644 src/bin/sim/doctor.rs diff --git a/src/bin/sim/checks_catalog.rs b/src/bin/sim/checks_catalog.rs new file mode 100644 index 0000000..65092f1 --- /dev/null +++ b/src/bin/sim/checks_catalog.rs @@ -0,0 +1,344 @@ +//! `sim checks --list [--json]` — the machine-readable catalog of what `cb-verify` +//! asserts, so an agent can discover the harness's contract WITHOUT reading +//! `src/checks/*` or `docs/CHECKS.md`. +//! +//!

The participants block is now derived from the pair instead of a const. - The pair also drives every service name derived from it — notably extra-validation's `rpc_url`, which was hardcoded to el-1-geth-lighthouse. The ethereum-package names EL services `el-{index}-{el}-{cl}` (el_launcher.star:177), so on any other pair that hardcode silently points at a nonexistent service and extra validation no-ops (feature.extra_validation would then WARN). Now derived — the exact coupling Law 7 exists to catch. - New scenario cb-basic-nethermind-prysm (P3's "one alternate EL/CL pair"): cb-basic's assertions on different clients. Full scenario x pair cross-product is deliberately left for later — this proves the parametrization end to end without exploding the fixture matrix. Every pre-existing golden is byte-identical (zero regression); 2 new tests pin both the participants flow and the rpc_url derivation. sim 68 -> 70.

Chain of evidence: prysm submits blinded blocks to /eth/v2/builder/blinded_blocks at ~256ms into the slot (early, so the "late block" hypothesis is dead); helix 404s that route; CB deliberately refuses to downgrade to v1 (in v2 the relay publishes the block after an empty 202, so forwarding a v1 payload would silently drop it) and returns 502. Result: every builder block the proposer chose was lost, and the 11 v2-unsupported events line up 1:1 with the 11 missed slots. Lighthouse never hit it because it submits via v1. The 404 was NOT a helix limitation: helix's Route enum has GetPayloadV2 (verified in the shipped binary alongside GetPayload, GetTopBidV2, ProposerPayloadDeliveredV2) and our generated router_config.enabled_routes listed only GetPayload. Added it. All goldens regenerated (the helix block is shared by every scenario). Also lands the check that would have named this in one line instead of a multi-hour chase: - NEW cb_relay_v2_unsupported reads pbs_submit_block_v2_unsupported_total, FAILs when nonzero (escalating to tier 1 like the matrix checks — lost submissions are at least as fatal as a 5xx) and points at the relay's route config first. - cb_v2_fallback no longer claims "relays support v2" when the counter is zero. That was a false reassurance: a relay that 404s v2 never reaches the fallback path at all, so zero fallbacks says nothing about v2 support. It now reports only what it measured ("No v2->v1 fallbacks recorded"). 6 tests (lib 121 -> 125). --- src/bin/sim/genmodel/helix.rs | 8 + src/checks/cb_metrics.rs | 145 +++++++++++++++++- .../cb-basic-nethermind-prysm.yml | 8 + tests/fixtures/golden-configs/cb-basic.yml | 8 + .../golden-configs/cb-extra-validation.yml | 8 + .../golden-configs/cb-multiple-relays.yml | 8 + tests/fixtures/golden-configs/cb-mux.yml | 8 + .../cb-sigverify-diff-control.yml | 8 + .../golden-configs/cb-sigverify-diff.yml | 8 + .../golden-configs/cb-skip-sigverify.yml | 8 + .../golden-configs/cb-timing-games.yml | 8 + 11 files changed, 222 insertions(+), 3 deletions(-) diff --git a/src/bin/sim/genmodel/helix.rs b/src/bin/sim/genmodel/helix.rs index 0c9d87b..e9701e2 100644 --- a/src/bin/sim/genmodel/helix.rs +++ b/src/bin/sim/genmodel/helix.rs @@ -53,6 +53,14 @@ router_config: replenish_ms: 50 burst_size: 20 - route: GetPayload + # The builder-spec v2 proposer route (submitBlindedBlockV2).

Writing it immediately caught real drift, including mine: cb_relay_v2_unsupported shipped in the previous commit without its catalog entry or CHECKS.md section - the exact failure the discipline exists to prevent. Both synced here (catalog now 24 entries; CHECKS.md gains the row + a section noting a FAIL usually means the relay's route config, not a capability gap).

Then wire the fetch fn into +`run_verification` in `src/main.rs`. The anti-pattern is welding the verdict into the `await` path: +`chain_health` and `relay_pipeline` still do this and are the standing gap. **Pick the tier deliberately** +(it is the severity contract) and prefer **WARN over a silent PASS** when the check could not actually +verify anything - that is how false-greens ship.

That is the Law-4 violation the law exists to prevent - these decide whether a release is gated. Extracted (behavior-identical, pure): - aggregate_builder_blocks: any-Pass wins and sums counts (one silent relay is not a pipeline failure since the builder only submits where configured), else worst-status. Empty input now SKIPs instead of panicking on .max().unwrap(). - aggregate_mev_rate: BEST-of (Pass wins) and collapses Skip => Fail, both deliberately opposite to CheckStatus::Ord - a Skip means no relay answered the data API, i.e. a failure to MEASURE delivery. The comment explaining why it is not unified with .max() now sits on the seam it describes. - aggregate_registrations: worst-status, per-relay labelled detail, and the documented "empty => omit the check entirely, not even SKIP" as an Option. 11 tests covering both sides of every boundary incl. the two panic guards (empty vec, urls/results length mismatch). relay_pipeline 24.5% -> 59.3% regions; lib 125 -> 136 tests; total coverage 62.3% -> 64.3%. --- src/checks/relay_pipeline.rs | 440 +++++++++++++++++++++++++---------- 1 file changed, 313 insertions(+), 127 deletions(-) diff --git a/src/checks/relay_pipeline.rs b/src/checks/relay_pipeline.rs index b050696..e979b46 100644 --- a/src/checks/relay_pipeline.rs +++ b/src/checks/relay_pipeline.rs @@ -360,6 +360,134 @@ fn all_relays_dead_results( /// at check time (mid-run death the startup preflight couldn't catch), the tier-1 /// delivery check FAILs (see `all_relays_dead_results`); otherwise the batch runs /// against the live relays. +/// Aggregate per-relay `builder_blocks_received` results (pure, Law 4 seam). +/// +/// PASS if ANY relay received blocks (the builder only submits to the relays it +/// is configured for, so one silent relay is not a pipeline failure), summing +/// the counts.

Any 2-helix scenario could hand a postgres container to the relay data-API checks. Switched to `contains`. Found by extracting the service-SELECTION logic out of discover() into a pure classify_services(services, port_fallback) seam (Law 4) - it decides WHAT gets checked, so a misclassification silently invalidates every downstream check, and it was previously unreachable without a live enclave. The extraction also restored a port-precedence contract: try every already-parsed port name BEFORE any `kurtosis port print` fallback. My first version interleaved them per-name, which would shell out for "http" before trying helix's parsed "endpoint" - one subprocess per relay per run, the same regression an earlier perf pass removed. Now asserted by call-counting tests. 10 tests incl. client-pair agnosticism (Law 7: names carry the pair), all three relay flavours vs their support services, pbs-over-http preference, optional CB metrics, and the two precedence guards. discovery 58.4% -> 79.8%; lib 141 -> 151. --- src/discovery.rs | 335 +++++++++++++++++++++++++++++++++++++---------- 1 file changed, 264 insertions(+), 71 deletions(-) diff --git a/src/discovery.rs b/src/discovery.rs index 9ea86a7..671b794 100644 --- a/src/discovery.rs +++ b/src/discovery.rs @@ -85,7 +85,7 @@ fn port_print(enclave: &str, service: &str, port_name: &str) -> Option { } /// A parsed service from kurtosis inspect output. -struct ParsedService { +pub struct ParsedService { name: String, ports: Vec<(String, String)>, // (port_name, url) } @@ -279,106 +279,111 @@ fn matches_pattern(name: &str, pattern: &str) -> bool { /// Discover all relevant services in a Kurtosis enclave. pub fn discover(enclave: &str) -> Result { - let mut result = EnclaveServices::default(); - let inspect_output = run_kurtosis(&["enclave", "inspect", "--full-uuids", enclave]) .wrap_err_with(|| format!("Could not inspect enclave '{enclave}'"))?; let services = parse_services(&inspect_output); if services.is_empty() { warn!("No services found in enclave '{enclave}'"); - return Ok(result); + return Ok(EnclaveServices::default()); } - info!("Found {} services in enclave '{enclave}'", services.len()); - for svc in &services { + // The only IO in the selection below: a `kurtosis port print` fallback for + // ports the inspect-table parse missed. + Ok(classify_services(&services, |svc, port| { + port_print(enclave, svc, port) + })) +} + +/// Decide which discovered services are the beacon nodes, relay APIs, CB +/// sidecars and prometheus, and pick a URL for each (pure, Law 4 seam). +/// +/// `port_fallback(service, port_name)` is consulted ONLY when the port was not +/// already parsed out of the `enclave inspect` table; tests pass a stub, the +/// real caller passes `kurtosis port print`.

That would make the mid-run death detector permanently blind without any error. Now pins all three liveness paths, the trailing-slash normalization (// 404s on some servers, same blindness), and that a refused connection IS reported as death. metrics.rs - a parse regression makes every matrix check SKIP, which is indistinguishable from the normal devnet state (metrics usually absent) and is non-fatal, so it would never surface.
