Make test/e2e/envs/loader.go capable of loading envs with one or many L2
networks, native or custom gas, op-stack or cdk-erigon sequencer, and one or
many aggkit services, while keeping op-pp fully working.

- Add Env.L2s []L2Config + PrimaryL2()/L2ByNetworkID() helpers; Env.L2 stays the
  backward-compatible primary-network accessor (lowest summary key, e.g. 001).
- Build an L2Config for every network in summary.json (deterministic order).
- Make MintableERC20 auto-deploy conditional on a per-env NativeGas capability;
  skip it for custom-gas/cdk-erigon. op-pp keeps deploying it.
- Add EnvCapabilities table (NativeGas, Sequencer, MultiNetwork, MultiAggkit)
  keyed by ENVName; op-pp reproduces today's behavior.
- Add ENVName constants: op-fep, op-fep-committee, op-pp-2chains, cdk-erigon-3chains.
- Parameterize aggkit service name, data dir, config path and keystore paths by
  network id (defaulting to aggkit-001 / config/001 / aggkit-001-data for op-pp).
- StopAggkit/StartAggkit keep no-arg behavior on the primary network; add
  StopAggkitService/StartAggkitService for targeting a specific aggkit.

Make test/e2e/envs/checks.go validate whatever topology an env declares and turn
the test-go-e2e workflow into an env matrix with dynamic per-env image pulls.

- checks.go: iterate all Env.L2s in checkConfiguration/checkL2Connectivity/
  checkL2Contracts; dial non-primary networks read-only; drop the hardcoded op-pp
  L2 chain id (2151908) in favor of live-vs-configured chain-id assertion; assert
  L1 chain id non-nil/positive; tag every error with the network SummaryKey/NetworkID.
- workflow: strategy.matrix over env_name (single op-pp entry now; P11 appends
  the rest as pure data); derive images via `docker compose config --images`
  (no hardcoded service list); per-env artifact names; E2E_ENV plumbed to
  make test-e2e -> TestMain; timeout 45 -> 90.
- TestMain: select env via E2E_ENV (default op-pp) using envs.ParseENVName; guard
  the post-test MintableERC20 bridge flow on Capabilities.NativeGas so non-native
  envs boot + sanity-check without nil-panic.
- envs: add KnownEnvs() and ParseENVName() helpers.
- Makefile: raise go test -timeout to 90m for consistency with the CI job timeout.

No new env dirs added and no tests ported (deferred to P7-P11).

Integrate the op-fep environment (single OP network in FEP / Full
Execution Proof mode, op-succinct mock prover, agglayer) generated from
the kurtosis-cdk feat/aggkit-e2e-envs branch via the op-fep.yml preset
and snapshot/snapshot.sh.

Contents mirror the op-pp env layout:
- summary.json: networks.l2_networks["001"] (chain_id 20201) with the
  op-geth EL key (P3 op-reth->op-geth reconciliation) and an
  op-succinct-proposer service marked settled:false (P3 FEP capture).
- docker-compose.yml + config/001 (rollup.json, genesis, keystores,
  jwt, entrypoints) + config/001/op-succinct (proposer env + configs +
  prover db dump) + config/agglayer (config.toml, aggregator.keystore).

The loader/checks (P5/P6) already support op-fep (EnvOpFEP, KnownEnvs,
envCapabilities NativeGas:true, checks.go L2s iteration). This commit is
a pure data + provenance addition; no Go code changed. make build and
golangci-lint run ./test/e2e/... are both green.

KNOWN BLOCKER (deferred to P3 snapshot-tooling owner): the snapshot
boots its L2 EL container (op-geth-001) from the discovered op-reth
image but with the op-geth entrypoint (apk add jq; exec geth), which
fails on op-reth (exit 127) so docker compose up / LoadEnv / CheckEnv
cannot complete. The op-succinct FEP package uses a real op-reth EL,
unlike op-pp's op-geth EL; generate-compose.sh's op-stack restore path
hardcodes the geth entrypoint against the discovered EL image. The
snapshot artifact itself is structurally valid and loader-compatible.

Completes the P7 CHANGE_REQUEST. The iteration-1 op-fep snapshot was
structurally valid but unbootable: the L2 EL service used the op-reth image
with the op-geth entrypoint (apk add jq; exec geth), so the container exited
127. Regenerated docker-compose.yml deterministically from the captured
snapshot state with the fixed kurtosis-cdk tooling (kurtosis-cdk b3e13ba9 on
feat/aggkit-e2e-envs):

  - L2 EL (op-reth) now runs op-reth-entrypoint.sh and uses a JSON-RPC POST
    healthcheck (op-reth rejects the op-geth GET probe with 405).
  - op-succinct proposer.env rewritten to the restored compose hostnames
    (op-node-001 / op-geth-001 / geth / beacon) and /app/configs mounted rw.
  - Dropped the now-unused op-geth-entrypoint.sh; added op-reth-entrypoint.sh.

testmain_test.go: bump the LoadEnv context from 1m to 5m. op-reth-backed FEP
envs take ~75s to bring the L2 EL dependency chain healthy (op-reth init + L1
producing up to the L2 origin block); op-pp is well under either budget.

Proven in this environment: docker compose up -d brings all core services
healthy (L1 geth/beacon/validator, op-reth EL, op-node, agglayer, aggkit,
postgres); E2E_ENV=op-fep go test -run TestMain passes LoadEnv + CheckEnv and a
full L1->L2 ERC20 bridge round-trip. make build + golangci-lint ./test/e2e/...
are green. L2->L1 FEP settlement remains blocked by the op-succinct proposer's
on-chain rollup-config-hash check, which a restored snapshot (re-anchored L2
genesis time) cannot satisfy — consistent with the snapshot's settled:false.

… & probe

Adds the op-fep-committee E2E environment: the op-fep FEP topology (op-reth EL,
op-node, agglayer, op-succinct mock proposer) PLUS an AggOracle committee
governed by an on-chain AggOracleCommittee proxy with a 2-of-3 quorum.

- test/e2e/envs/op-fep-committee/: snapshot generated from kurtosis-cdk
  feat/aggkit-e2e-envs @ d71f4265 (committee-capture path) using the
  op-fep-committee.yml preset (use_agg_oracle_committee: true, quorum 2,
  total_members 3, additional_services: []). Mirrors the op-fep layout and adds
  the two restored AggOracle committee member services + their captured
  keystores under config/001/committee/00N/etc, plus the committee proxy address
  in summary.json (contracts.aggoracle_committee).
- loader.go: bind the on-chain AggOracleCommittee contract
  (L2Contracts.AggOracleCommittee / AggOracleCommitteeAddress) when summary.json
  carries the committee address, exposing read-only Quorum() /
  GetAllAggOracleMembers() / GetAggOracleMembersCount(). Inert (nil) for
  non-committee envs.
- committee_probe_test.go: a minimal load+read probe (NOT a migrated test) that,
  through the loaded env's bound contract, verifies the on-chain committee
  quorum (2) and membership (true M-of-N). Skips for non-committee envs.
- README.md: op-fep-committee provenance (kurtosis-cdk d71f4265, preset args,
  how the committee services + keystores + address were captured).

Verified: docker compose up brings op-reth EL + op-node + aggkit + both
committee members healthy; LoadEnv binds the committee; CheckEnv passes; the
quorum probe reads quorum=2 / members=[admin + 3 aggoracle signers] on-chain and
passes. The L2->L1 FEP settlement (settled:false / L1-Info-Tree injection) is the
known architectural op-fep limitation and is out of scope here.

…PC fix

Add a real kurtosis snapshot env with TWO OP-PP (ecdsa-multisig) L2 networks
(001=chainId 20201/net 1, 002=chainId 20202/net 2) sharing one L1 + agglayer,
generated from kurtosis-cdk feat/aggkit-e2e-envs @ d71f4265 via the multi-doc
preset .github/tests/aggkit-e2e-envs/op-pp-2chains.yml (two `---` docs applied
sequentially into one enclave). summary.json lists both networks with distinct
ports/contracts/accounts; compose carries both op-geth/op-node/aggkit stacks
plus the shared L1 (geth/beacon/validator) and agglayer.

Loader fix: non-primary L2 networks were dialed via the aggkit node RPC
(AggsenderRPCURL), which does not serve eth_* — so CheckEnv failed for chain
002. Add L2Config.OpGethRPCURL (from services.op-geth.http_rpc.external) and
make clientForNetwork prefer it. LoadEnv now exposes len(L2s)>=2 and CheckEnv
validates both chains.

Includes a generic per-chain health probe (zz_p9_probe_test.go) asserting
chainId/advancing block/non-zero balance for 001 and 002. No L2<->L2 bridging
test (out of scope).

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Adds the cdk-erigon-3chains E2E env: three cdk-erigon (pessimistic,
ecdsa-multisig) L2 networks sharing one L1 + agglayer. Networks 001
(chain id 2151908) and 002 (20202) use a custom gas token; 003 (20203)
is native ETH. This is the first cdk-erigon-sequencer env and the first
mixed custom-gas env.

Loader (bounded, op-* envs unaffected):
- summaryL2Network gains a "cdk-erigon" service struct and contracts
  "gas_token". New l2RPCURLForNetwork helper selects the per-network L2
  EL RPC (prefer op-geth, else cdk-erigon); used by the client dial,
  L2Config.OpGethRPCURL (kept populated sequencer-agnostically for
  op-stack byte-compatibility; rename flagged for P12) and waitForServices.
- L2Contracts.GasTokenAddress surfaces the custom gas-token address.
- Per-network gas model: MintableERC20 auto-deploy gated on
  (env NativeGas) AND (network has no gas_token). EnvCDKErigon3Chains
  NativeGas means "native deploys permitted" (true): 001/002 skip the
  deploy + surface their gas token, 003 deploys MintableERC20.

checks.go validates all three networks unchanged (topology-agnostic).
zz_p10_probe_test.go is a verification harness only (per-chain chainId +
advancing block + live NetworkID, gas token surfaced for 001/002) — no
migrated bridge test. CI matrix wiring deferred to P11.

Verified: docker compose up -d brings all 11 services healthy; LoadEnv
exposes 3 L2s, CheckEnv passes, the probe is GREEN; make build and
scoped golangci-lint run ./test/e2e/... are clean.

…to test-go-e2e CI matrix; settlement-excluded FEP smoke gate

Add the four new envs to the test-go-e2e workflow as a trigger-gated matrix:
a setup-matrix job emits the env_name list (op-pp only on pull_request; all
five on nightly schedule + workflow_dispatch) consumed by both the
pull-docker-images and test-go-e2e job matrices via fromJSON, keeping their
legs one-to-one. Dynamic image derivation, per-env artifact names, and the
90m timeout are inherited unchanged.

Add a SettlementSupported capability flag (loader.go): false for op-fep and
op-fep-committee (documented L2->L1 FEP settled:false limitation -> boot/
load/checks smoke only), true for op-pp, op-pp-2chains, cdk-erigon-3chains
and for the unknown-env fallback (preserves prior op-pp behavior). TestMain's
post-test bridge/settlement health-check is now additionally gated on this
flag so FEP legs skip it (clear [POSTTEST] log) while non-FEP NativeGas legs
keep the full flow.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Consolidate test/e2e/envs/README.md for structural consistency across the
four new envs: add the missing op-fep Loader bullet (EnvOpFEP capabilities,
OpGethRPCURL dialing, and the SettlementSupported:false post-test
bridge-settlement gate) so op-fep mirrors its op-fep-committee/op-pp-2chains/
cdk-erigon-3chains siblings. All cited kurtosis-cdk SHAs and preset paths
verified to exist on feat/aggkit-e2e-envs.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
LoadEnv started the env with a bare `docker compose up -d`, which returns as
soon as containers are created. With the snapshot composes' health-gated
`depends_on` conditions, a cold host (images loaded for the first time) can let
a slow-to-become-healthy dependency (agglayer, op-geth) abort startup. This was
reproduced while validating all envs: bare `up -d` aborted op-pp / op-pp-2chains
on cold start, while `up -d --wait --wait-timeout` booted every env healthy.

Use `--wait --wait-timeout 600` so boot blocks until all services are
healthy/running, with a timeout generous enough for the heavier envs
(FEP prover, aggoracle committee, multi-chain). Verified: op-pp boots healthy
through LoadEnv + CheckEnv + an L1->L2 bridge round-trip; make build + scoped
golangci-lint green.

…her + op-node finality flags)

Regenerates the committed op-pp snapshot env from kurtosis-cdk
feat/aggkit-e2e-envs df96c41e using an op-geth-backed OP-PP enclave brought up
from the new .github/tests/aggkit-e2e-envs/op-pp.yml preset.

What changed vs. the previous committed op-pp:
- docker-compose.yml: adds the op-batcher-001 service (op-batcher:v1.16.9,
  --data-availability-type=calldata, funded --private-key, depends_on geth +
  op-geth-001 + op-node-001). op-node-001 now runs with --l1.http-poll-interval=2s
  and --l1.epoch-poll-interval=12s. op-geth-001 exposes the miner API namespace
  (http/ws) so the batcher's startup miner_setMaxDASize succeeds.
- summary.json: networks.l2_networks.001.services now includes "op-batcher"
  (batches_to_l1: true) alongside op-geth/op-node/aggkit. Loader-facing keys
  (op-geth http_rpc, aggkit rpc/rest, L1 geth, chain_id 20201) unchanged, so the
  loader's summaryJSON still parses and make build + golangci-lint stay green.
- config/001: regenerated keystores/genesis/rollup/aggkit-config; adds
  op-batcher-cmd.json (captured batcher launch config, audit).

Restored-env finality proof (scratch copy, remapped ports, distinct prefix,
docker compose up -d --wait): L2 finalized advanced 0 -> 156 -> 191 -> 203 ->
239 (monotone), L1 finalized advancing in lock-step, op-geth finalized tag
matched op-node, op-batcher healthy + posting calldata batches.

README op-pp provenance updated (new kurtosis-cdk commit, the preset, the three
folded fixes, the op-geth EL pin, and the L2-finalizes-on-restore note).

… (op-batcher + op-geth EL + finality flags)

Overwrite test/e2e/envs/op-pp-2chains/ with a snapshot regenerated from the
updated kurtosis-cdk preset (op-geth EL + op-node finality flags + miner API on
both chains 001 and 002). Mirrors the single-chain op-pp regeneration:

- docker-compose.yml: both chains now carry op-batcher-00N (image
  op-batcher:v1.16.9, funded --private-key, --data-availability-type=calldata,
  hostnames rewritten to that chain's op-geth-00N/op-node-00N + shared geth,
  ports 11548/12548) alongside op-geth-00N/op-node-00N/aggkit-00N + shared
  L1 (geth/beacon/validator) + agglayer (12 services total).
- L2 EL switched op-reth -> op-geth: op-reth-entrypoint.sh removed,
  op-geth-entrypoint.sh added per chain (exposes the miner API so the batcher's
  startup miner_setMaxDASize succeeds). op-node-entrypoint.sh carries
  --l1.http-poll-interval=2s + --l1.epoch-poll-interval=12s on both chains.
- summary.json: each L2's services now include op-batcher (batches_to_l1: true);
  loader-facing keys (op-geth http_rpc, op-node, aggkit, L1 geth, chain_ids
  20201/20202) intact and backward-compatible.
- Added config/00N/op-batcher-cmd.json (audit). Kept only l2-genesis.json.bak.
- README op-pp-2chains provenance rewritten with the fix set + the restored
  both-chains finality proof (001 & 002 finalized 0 -> 23 -> 35 in lock-step).

make build + golangci-lint run ./test/e2e/... green; loader summaryJSON parses
both networks (001/002 op-geth RPC + chain ids resolve).

…nality flags + op-reth miner API)

Regenerated test/e2e/envs/op-fep/ from a fresh op-fep enclave snapshot taken
with kurtosis-cdk fc745b2e. Folds in the finality fix set proven on
op-pp/op-pp-2chains, adapted for FEP's op-reth EL:

- op-batcher-001 compose service added (image op-batcher:v1.16.9, funded
  --private-key, DA=calldata, hostnames -> geth/op-geth-001/op-node-001,
  port 11548:8548); summary op-batcher service with batches_to_l1:true. This
  posts L2 batch data to L1 so the L2 safe/finalized heads advance (in FEP mode
  the ZKP proves against this L1 batch data).
- op-node-entrypoint.sh: --l1.http-poll-interval=2s + --l1.epoch-poll-interval=12s.
- op-reth-entrypoint.sh: 'miner' added to --http.api/--ws.api for
  op-batcher miner_setMaxDASize.
- op-succinct-proposer + postgres preserved (settled:false unchanged); op-reth
  v2.2.5 EL kept (op-succinct/FEP requires it). Loader-facing summary keys intact
  (op-geth http_rpc, op-node, aggkit rpc/rest, L1 geth, chain_id 20201).
- config/001/op-batcher-cmd.json added (audit), matching op-pp convention.
- README op-fep provenance rewritten: EL=op-reth rationale, fix set, native
  finality proof (L2 finalized 0->76->100->124), FEP settlement note.

Native finality proven on the live enclave. lint ./test/e2e/... = 0 issues.

Regenerate test/e2e/envs/op-fep-committee/ from a fresh op-fep-committee
snapshot (kurtosis-cdk c8740844) carrying the proven op-pp/op-pp-2chains/
op-fep finality fix set, while preserving the AggOracle committee:

- op-batcher-001 added to docker-compose.yml + summary.json
  (batches_to_l1: true); op-batcher-cmd.json captured for audit.
- op-node finality flags in config/001/op-node-entrypoint.sh
  (--l1.http-poll-interval=2s, --l1.epoch-poll-interval=12s).
- op-reth miner API in config/001/op-reth-entrypoint.sh so op-batcher's
  miner_setMaxDASize succeeds on restore.
- Committee members 000/001 (aggoracle-N.keystore), op-succinct config,
  postgres, and contracts.aggoracle_committee all preserved.

Restored-env proof (isolated, remapped ports, op-reth EL): L2 finalized
advanced 0 -> 10 -> 22 -> 58 -> 70 -> 118 (op-geth finalized tag matched
op-node), L1 finalized 203 -> 283, op-batcher healthy + posting. Committee
quorum re-verified on the restored proxy: quorum()=2, 4 members. FEP
settlement remains settled:false (architectural, out of scope). README
provenance updated; make build + scoped golangci-lint green.

#	test/e2e/envs/op-pp/docker-compose.yml
The op-pp snapshot baked an on-chain aggsender validator multisig
(threshold 2 of 3) but ran no aggsender-validator-00N containers, so the
aggsender stalled at "validatorPoller threshold not reached: 1/2", never
sent a certificate, and the agglayer cert header stayed null. That broke
every cert-dependent test (notably L2->L1 bridge claims).

Regenerate test/e2e/envs/op-pp/ from the single-signer kurtosis-cdk
preset (.github/tests/aggkit-e2e-envs/op-pp.yml @ 89dedc4f:
use_agg_sender_validator=false, agg_sender_multisig_threshold=1,
agg_sender_validator_total_number=0). The lone aggsender now self-validates
(1/1); the regenerated aggkit-config.toml no longer carries an
[AggSender.ValidatorClient] block and no remote validator members are
baked on-chain.

Proven on an isolated restore (E2E_ENV=op-pp, all 8 services healthy):
- aggkit-001 logs: 0 "threshold not reached" / validatorPoller lines.
- interop_getLatestKnownCertificateHeader([1]): null (before) -> a cert
  with status "Settled", a real settlement_tx_hash and a non-zero
  new_local_exit_root (after an L2 bridge exit).
- L2->L1 bridge claimable: bridge service /l1-info-tree-index returned a
  non-zero index (rollup-exit-root landed on L1), claim proof fetched, and
  the L1 claimAsset tx mined ("L2->L1 flow completed successfully";
  "[POSTTEST] Bridge flows post-test check succeeded"; e2e exit 0).
- Finality preserved: L2 finalized advanced 0 -> 15 -> 26 -> 50 -> 74.
  op-batcher capture + op-node finality flags + op-geth miner API intact.

make build, go vet ./test/e2e/..., golangci-lint run ./test/e2e/... all

…; certs settle)

Regenerate the op-pp-2chains e2e snapshot from the single-signer kurtosis-cdk
preset (.github/tests/aggkit-e2e-envs/op-pp-2chains.yml @ 89dedc4f:
use_agg_sender_validator: false, agg_sender_multisig_threshold: 1,
agg_sender_validator_total_number: 0 on BOTH chain documents).

Both chains' aggkit-config.toml no longer carry an [AggSender.ValidatorClient]
block and no remote validator members are baked on-chain, so each lone
aggsender self-validates 1/1 instead of stalling at 'threshold not reached: 1/2'
(the old multisig-without-validators regression that left both networks' agglayer
cert header null and broke L2->L1 claims).

Finality fixes preserved on both chains (op-batcher per chain, op-node
--l1.http-poll-interval=2s + --l1.epoch-poll-interval=12s, op-geth EL + miner
API). Snapshot op-pp2c-20260602-222717.

Verified on an isolated restore (remapped ports, oppp2csr- prefix, all 12
services healthy): both aggkit-001/002 up with 0 'threshold not reached' lines,
each self-validating 1/1; both L2s finalized 0->24. Cert null->Settled could not
be captured in this restore window because the restored shared L1 EL stopped
sealing under extreme concurrent host load (load avg ~50) - the documented
loaded-host L1-EL stall, not a snapshot/preset defect; the identical single-signer
fix is proven to settle certs on the single-chain op-pp env. make build / go vet
./test/e2e/... / golangci-lint ./test/e2e/... green; loader parses both networks.

…sig)

Regenerate the committed op-fep e2e env from the single-signer kurtosis-cdk
preset (feat/aggkit-e2e-envs @ 89dedc4f: use_agg_sender_validator=false,
threshold 1, total 0) so the restored aggsender no longer stalls on a phantom
validator-multisig quorum.

The previous op-fep snapshot's aggkit-config.toml carried an
[AggSender.ValidatorClient] URL = "aggkit-validator-001:5578" block that made
the aggsender wait on an external validator service that does not exist in the
snapshot (validatorPoller threshold not reached). The regenerated config has NO
[AggSender.ValidatorClient] block: the aggsender self-validates 1/1 in-process
and reaches sendCertificateWithRetries, then the documented FEP op-succinct
proof step (settled:false is the architectural limitation, not a quorum stall).

Captured with kurtosis-cdk tool commit 48a0a00b (hardened graceful serial L1
docker stop, no docker kill) which fixed the op-reth/validator loaded-host
container-stop wedge. Verified by an isolated restore (distinct compose project
+ remapped ports, up -d): geth baked-L1 healthy, op-reth EL boots past the L1

…multisig quorum

Regenerate the op-fep-committee snapshot so the restored env genuinely runs the
on-chain aggsender validator multisig (threshold 2 / total 3) instead of being
stuck on "validatorPoller threshold not reached" (the op-pp regression).

The capture now includes the two aggsender-validator services
(aggkit-001-aggsender-validator-002 / -003, --components=aggsender-validator,
gRPC :5578) whose hostnames match the on-chain aggchainParams.signers multisig
URLs, each with its aggsendervalidator-N.keystore. Their config.toml L1/L2
hostnames are rewritten to the restored compose hostnames so they boot instead
of crash-looping on DNS.

Isolated-restore verification (remapped ports/prefix, up -d --wait):
- primary aggsender: NO "validatorPoller threshold not reached" loop; it gets
  past the multisig step (only later stops at the absent aggkit-prover aggchain
  proof — the documented FEP settled:false limitation, unchanged).
- both validators run stable (no restart loop), serving gRPC.
- AggOracleCommittee preserved: quorum()=2, 4 members on-chain (genuine M-of-N).
- L2 finality preserved: finalized advanced to 94 (> 0).

make build + go vet ./test/e2e/... + golangci-lint ./test/e2e/envs/... green;
loader package compiles and recognizes E2E_ENV=op-fep-committee.

…-pp env

The op-pp env regeneration (op-batcher L2 finality + single-signer committee +
TriggerCertMode=EpochBased) broke the pre-existing backward_forward_let tests.
Three stacked env regressions, all fixed within the test file:

1. UNIQUE constraint on certificate_info.height: the live aggsender is slow to
   settle its first cert under EpochBased, so injection built at height 0 and
   collided with the aggsender's pending height-0 row. New ensureAgglayerHasSettledCert
   drives a warm-up L1->L2 bridge-and-claim and waits for the first settle, so
   injection builds at SettledHeight+1.

2. Diagnose -> NoDivergence: the malicious cert settles fast, then the live
   aggsender's recovery rewrites the injected DB row to an AggLayer-source
   placeholder, so its RPC returns NotFound and Diagnose flags it missing. Capture
   injected exits in bflInjectedExits and feed Diagnose the tool's --cert-exits-file
   override via prepareBFLToolConfigWithInjectedExits.

3. (Case3/4) second cert built on wrong leaf count: buildMaliciousCert's existing-
   leaves reconstruction skipped the AggLayer-reconciled first injected cert, so the
   second cert's NewLocalExitRoot was wrong. Prefer bflInjectedExits when rebuilding.

AggsenderAPIFallback: 3-tier missing-cert->exits resolution (injected exits /
pre-collected ID via admin API / empty list for legit no-exit certs).

Verified live: Case1/Case2 pass full package; Case3/Case4/AggsenderAPIFallback test
bodies pass; AggsenderAPIFallback->TestBridgeNightly sequence both pass (cascade
fixed); removeGER B1/B2 pass standalone (full-suite flakiness is pre-existing,
out of scope). go vet + tool builds clean.

…hange)

Two pre-existing flaky paths on the regenerated op-pp env, both addressed in the
test harness / env orchestration only — the aggsender is intentionally untouched.

1. Bridge-service pagination (suite-ordering flake, e.g. removeGER B "bridge not
   found"): GetBridges lookups scanned only the first 100 bridges, so the target is
   missed once a prior test created >100 bridges in the shared env.
   - waitForBridgeByTxHash (helpers_test.go): paginate across ALL pages, using the
     response Count as the stop condition (ordering- and count-agnostic).
   - bridge_utils.go L1->L2-claim and L2->L1 scans: filter by DepositCount parsed
     from the BridgeEvent receipt log (page-independent), matching the existing
     no-claim helper.

2. Post-suite L2->L1 epoch-notifier freeze: the aggsender's epoch-notifier L1 block
   subscription can intermittently freeze after repeated aggkit restarts (BFL
   Case3/Case4), stalling cert settlement so the L2->L1 exit never becomes claimable
   and the post-suite check burned the whole budget. testmain now runs the L2->L1 leg
   with an 18m first attempt and, on failure, does ONE StopAggkit+StartAggkit restart
   to re-establish the subscription, then retries (total budget 25m->35m). The restart
   only fires on failure, so healthy runs are unaffected.

go vet + golangci-lint (0 issues) green.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The aggkit-restart recovery added in 9fbf7d6 fires correctly but does NOT recover
the epoch-notifier freeze: live verification showed a single StopAggkit+StartAggkit
re-triggers the L2ClaimSyncer block-0 wedge ("UNIQUE constraint failed: block.num",
climbing past attempt 100), so the bootstrap race just re-runs, the epoch-notifier
never resumes, and no cert settles. The restart is therefore counterproductive and
gives a false impression of recovery, so restore the original parallel post-suite
block (25m budget).

The pagination fix from 9fbf7d6 (helpers_test.go, bridge_utils.go) is independently
verified working (removeGER B1/B2 pass in-sequence on a shared env, 0 "bridge not
found") and is kept.

The real fix for the post-suite L2->L1 freeze lies in the aggsender/env (claim-syncer
block-0 re-insert on restart + epoch-notifier subscription freeze), i.e. the
"strictly necessary" threshold that needs a separate decision.

…ck-0 wedge

The claim syncer's block insert used a plain meddler.Insert, so a duplicate insert
of the same block raised "UNIQUE constraint failed: block.num". This happens because
the aggsender bootstrap (SetClaimSyncerNextRequiredBlock -> SyncNextBlock) can race
the main Sync loop on the genesis block, and a restart re-processes the configured
starting block. The driver retries ProcessBlock infinitely on that error, so the
L2ClaimSyncer wedges, the aggsender never finishes Start(), and no certificate ever
settles (observed live: 100+ "failed to insert block 0" retries, aggsender never
reaches the epoch notifier).

Mirror bridgesync's block insert (#1539 split dropped this): use an idempotent
upsert `INSERT INTO block (num, hash) VALUES (...) ON CONFLICT (num) DO UPDATE SET
hash = ...`, so a duplicate insert of the same block is a harmless no-op instead of a
wedging error. This is defense-in-depth alongside the existing
shouldAutoStartL2ClaimSync resolution (which only avoids the race when correctly
built into the image). Adds TestInsertBlock_Idempotent.

…-p 1/E2E_RUN

Two foundational pieces for the P11 CI work:

1. The test/e2e/envs P9/P10 probe tests (zz_p9/zz_p10_probe_test.go) call
   LoadEnv(op-pp-2chains)/LoadEnv(cdk-erigon-3chains) unconditionally and have no
   TestMain, so under `go test ./test/e2e/...` they boot concurrently with the main
   e2e suite's env and collide on host ports (:8545). Gate each to its own CI leg via
   E2E_ENV so they skip in the op-pp suite leg.

2. make test-e2e: add `-p 1` so package execution serializes (suite TestMain vs the
   envs-package probes never boot docker concurrently), and an optional `E2E_RUN`
   -run filter so the CI matrix can shard op-pp into separate fresh-env legs for the
   non-destructive bridge tests vs the destructive BFL/removeGER/committee tests
   (which manipulate aggsender/GER state and leave the aggsender DB diverged from
   agglayer, wedging later settlement-dependent tests in a shared env).

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
…rk operational

Tests must be order-independent and leave the network operational. AggsenderAPIFallback
advances agglayer (malicious cert + recovery) while wiping the local aggsender DB, then
its cleanup restored the original config pointing back at a DB whose latest settled cert
is many heights behind agglayer. On the next aggkit start that hits statuschecker CASE 4
("Local certificate ... is different from agglayer ... Manual recovery required: wipe the
aggsender DB") and the aggsender wedges forever, poisoning every later settlement-dependent
test in a shared env (observed: TestBridgeCore/ERC20DepositL2ToL1 stalled after the BFL block).

Fix: in cleanup, after restoring the config, also delete the stale aggsender sqlite (+wal/-shm)
so the aggsender re-bootstraps cleanly from agglayer (CASE 2: no local cert -> insert agglayer's
latest settled cert) and resumes settling, leaving the network healthy for the next test.

…namic claim)

CategoryA used a crafted bats proof fixed to mainnet deposit_count=2, which prior
tests' sequential L1->L2 claims consume, so its dummy ClaimAsset reverted
("execution reverted") when CategoryA ran after other tests — violating order
independence.

Relocate CategoryA's fabricated claim to a fresh, never-claimed deposit count
(dummyCategoryADepositCount, well below the 2^32 exit-tree capacity) and build its
local proof + invalid GER dynamically (new buildDynamicClaimProof, extracted from
buildB1ClaimProof; new mainnetGlobalIndex helper). The leaf has no matching real
bridge, so the tool still classifies it ScenarioCategoryA. Removed the now-dead bats
fixtures (batsGER1, mainnetExitRootBats, rollupExitRootBats, batsLocalExitRootProof,
batsGlobalIndexCategoryA, mustParseBatsLocalProof, mustSetBigInt,
batsCategoryADummyClaimParams).

Verified live: TestBridgeCore (claims deposit_count 0,1,2) then TestRemoveGER_CategoryA
in sequence -> CategoryA PASS (22s, "GER removed from L2"), where it previously
instant-reverted. go vet + golangci-lint clean.

…rger amount)

TestBridgeCore/NativeTransferL1ToL2 intermittently failed its "fee shortfall is a tiny
fraction of the amount" assertion (observed fee 3.4e13 ~= 33% of the 1e14 amount during
an L2 gas-price spike). The recipient is also the claim-tx gas payer, and the claim fee
(L2 execution gas + an unsurfaced L1 data fee) is roughly FIXED regardless of amount, so
a tiny 0.0001 ETH amount made the fee a large, gas-price-dependent fraction.

Bump bridgeCoreNativeAmount 1e14 -> 1e17 (0.1 ETH, matching the ERC20 case) so the fixed
fee is a negligible fraction with ample margin for gas spikes. Verified: TestBridgeCore
all 4 subtests PASS.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
…th (real fix)

The previous attempt (7c6018d) tried to delete the aggsender DB via GetAggsenderDBPath()
in cleanup, but op-pp's aggkit-001 has no ./aggkit-001-data:/tmp bind-mount, so the DB is
container-internal and that host path doesn't exist — os.Remove silently no-op'd and the
stale DB persisted. In a full in-order run the aggsender then wedged in CheckInitialStatus
CASE 4 (local height behind agglayer, "manual recovery required") at the cleanup restart and
stayed wedged, hanging the next settlement-dependent test (TestBridgeCore/ERC20DepositL2ToL1).

Fix: restart the aggsender on a FRESH empty StoragePath in cleanup instead of restoring the
stale one. With no local cert, CheckInitialStatus takes CASE 2 and inserts agglayer's latest
settled cert AT its agglayer height (Height: cert.Height), so local stays aligned with agglayer
(later restarts hit CASE 5, never CASE 4) and the aggsender resumes settling — network left
operational and the suite order-independent. No host DB access needed.

Verified: full BFL block (NoDivergence, Case1-4, AggsenderAPIFallback) then TestBridgeCore all
PASS, incl. ERC20DepositL2ToL1 (which hung before); 0 wedge, 0 UNIQUE, package ok.

…c after restart

A StopAggkit+StartAggkit restart waits for the bridge service to become ready again
(StartAggkit -> waitForBridgeService). The 2m budget was below the env's own
serviceReadyTimeout (4m), so deep in a busy in-order suite the restart intermittently
failed with "wait for bridge service after start: context deadline exceeded"
(observed in AggsenderAPIFallback's Phase-2 wipe restart AND its cleanup restart),
which aborted the test and cascaded into later settlement tests (BridgeCore,
CertificateSettlement). Raise to 5m (>= serviceReadyTimeout + margin) so the bridge
service gets its full readiness window after a restart.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Address the failures that only surface deep in a full in-order run (all pass in isolation):

1. removeGER CategoryB2 — the tool resolves the fake claim's "CorrectBridge" by matching leaf
   CONTENT (origin/dest/amount/metadata); a round 0.0002 ETH amount to the same pooled destination
   collides with other tests' bridges accumulated in the shared env, so it resolved a different
   bridge (wrong deposit_count). Use a distinctive unique amount so the content match is unambiguous.

2. CommitteeUpdates (and any L1->L2 bridge+claim) — the L2 ClaimAsset was sent before the claim's GER
   was set on the L2 GlobalExitRoot contract; the bridge service reports the leaf "injected" slightly
   before aggoracle updates the L2 contract, and the lag grows deep in a busy suite, so ClaimAsset
   reverted at gas estimation ("GER not found"). Add waitForGERPresentOnL2 gating on
   GlobalExitRootMap(ger)>0 before both L1->L2 ClaimAsset sites in bridge_utils.go.

3. TriggerCertModes — bumped the observe window 15m->25m: deep in the suite the aggsender's per-epoch
   settlement cadence under load can exceed a tight window; the test stops early on the first height
   advance, so this only caps the worst case.

Also gofmt the bflRestartTimeout const block. go vet + golangci-lint clean.

…on fix)

The unique amount (2d30da6) was insufficient: a second bridge with the same amount and
the same pooled destination still appeared in the shared env, so the removeGER tool's
content-based CorrectBridge resolution returned the wrong bridge (wrong deposit_count).
Thread an optional `dest` through performBridgeL1NoClaim/BridgeL1NoClaim (zero = the
pooled L2 key, preserving B1/sovereign behavior) and have CategoryB2 bridge to a fresh
random recipient, so its leaf content (origin/dest/amount/metadata) is unique and the
resolution is unambiguous regardless of run order. bridge1.DestinationAddr flows through
the deferred fake-claim, so the fresh dest stays consistent.

…dex at claim time)

TestBridgeNightly's deferred claim helpers (claimERC20L1ToL2, claimMessageL1ToL2) were
using the L1-info-tree index captured at bridge time (b.l1InfoIndex) to fetch the claim
proof. That stale index may reference a GER that aggoracle later skips or that a reorg
invalidates, so the claim reverts at gas estimation ("execution reverted") when that GER
is not yet in the L2 GlobalExitRoot contract at claim time.

Fix: re-fetch the L1-info-tree index via waitForL1InfoTreeIndex + waitForInjectedL1InfoLeaf
at claim time in both helpers, then build the proof against the currently-valid,
stably-injected index. The proof is fetched fresh at the current index, so the claim
always uses a GER that aggoracle has already set on L2. go vet clean.

Two gaps in the existing workflow:

1. timeout-minutes 90 -> 120: the go test -timeout is 90m (make test-e2e), so the
   job timeout was equal to the test timeout with no buffer for runner setup, docker
   image loading, and the artifact-upload step. With timeout-minutes == go test
   timeout, GitHub Actions would kill the job before go test exits cleanly and the
   failure log artifacts would not be collected. Raise to 120m (30m buffer).

2. "Install Docker Compose" step replaced with "Verify Docker Compose plugin": the
   previous step installed the legacy v1 docker-compose standalone binary via apt,
   which would shadow the v2 plugin (docker compose) that the test code uses via
   exec.Command("docker", "compose", ...) in loader.go. Ubuntu runners ship with
   the v2 plugin pre-installed; the step now verifies it is present without
   installing the incompatible v1 binary.

🚀 What's New

This PR migrates all E2E tests from the legacy bash/bats testing framework to Go-based tests, adding support for multiple test environments (op-pp, op-fep, op-fep-committee, op-pp-2chains, cdk-erigon-3chains). All 9 bats files have been successfully migrated with equivalent Go test coverage. The migration includes extensive documentation, new test helper infrastructure, custom Solidity contracts for testing, and generalized environment loading capabilities.

🐛 Bug Fixes

  • Critical: Fixed claimsync race condition causing aggsender wedge on block 0 insertion (cmd/run.go, claimsync/storage/storage.go)
  • claimsync: Made block insertion idempotent using ON CONFLICT DO UPDATE to prevent UNIQUE constraint failures

📋 Config Updates

  • New environment configurations for 5 test environments under test/e2e/envs/
  • Updated workflow timeouts: test-go-e2e.yml increased from 45m to 120m
  • Added dynamic environment matrix in CI workflows for PR vs. nightly test selection

⚠️ Breaking Changes

None - this is additive migration work with backward compatibility maintained.


Review Feedback

🔴 Required Issues

1. PR Size - Difficult to Review Thoroughly

Severity: High
Location: Entire PR (100 files, 127,421 additions, 548 deletions)

This PR is extremely large and mixes multiple concerns:

  • E2E test migration (primary goal)
  • Production bug fixes (claimsync race condition)
  • New environment infrastructure (5 environments)
  • Documentation updates
  • Workflow changes

Impact: The size makes thorough security and correctness review very challenging. Critical bugs could be missed.

Recommendation: Consider splitting into smaller, focused PRs:

  1. Production bug fixes (claimsync race, cmd/run.go fix) - can merge independently
  2. Core test migration (P1-P10)
  3. Environment infrastructure (new envs)
  4. Workflow updates

If keeping as one PR, ensure multiple experienced reviewers examine different subsystems.

Fix this →

2. Production Bug Fix Mixed with Migration

Severity: Medium
Location: claimsync/storage/storage.go:146-158, cmd/run.go (new helper function)

The PR includes a critical production bug fix (claimsync block-0 race condition) embedded within a massive migration PR. This fix should ideally be:

  • Reviewed independently with high priority
  • Backported to stable branches if needed
  • Not buried in 127K lines of test code

Recommendation: Extract the production fixes into a separate PR or clearly document they are included and require careful review.

Fix this →

🟡 Suggested Improvements

3. Test Timeout Hardcoding

Severity: Low
Location: test/e2e/bridge_test_core_test.go:30-33

const (
	bridgeCoreL1ToL2Timeout = 8 * time.Minute
	bridgeCoreL2ToL1Timeout = 40 * time.Minute
)

Hardcoded 40-minute timeout for L2→L1 seems excessive for normal operations and suggests potential performance issues or flaky tests.

Recommendation:

  • Investigate why 40 minutes is needed
  • Consider making timeouts configurable via environment variables
  • Add comments explaining why such long timeouts are necessary

4. Fee Tolerance Calculation Could Be More Robust

Severity: Low
Location: test/e2e/bridge_test_core_test.go:312-313

feeTolerance := new(big.Int).Div(bridgeCoreNativeAmount, big.NewInt(50))

The 2% fee tolerance (amount/50) was adjusted from 0.1% due to observed OP-Stack L1 data fees. This seems brittle.

Recommendation:

  • Consider calculating actual fees from receipts where possible
  • Add explicit logging of fee components for debugging
  • Document the L1 data fee calculation limitations in comments

5. Lack of Input Validation in Smart Contracts

Severity: Low
Location: test/contracts/internalclaims/InternalClaims.sol, test/contracts/bridgemessagereceivermock/BridgeMessageReceiverMock.sol

The test mock contracts don't validate inputs in updateParameters() functions. While these are test-only contracts, they could still benefit from basic sanity checks.

Recommendation: Add basic validation (non-zero addresses, reasonable amounts) even for test contracts to catch configuration errors early.

6. Error Messages Could Be More Descriptive

Severity: Low
Location: test/e2e/envs/loader.go (various locations)

Some error messages don't provide enough context for debugging, especially in the complex multi-environment loader logic.

Recommendation: Enhance error messages with more context:

// Current
return fmt.Errorf("failed to load env: %w", err)

// Better
return fmt.Errorf("failed to load env %s from %s: %w", envName, envDir, err)

🟢 Optional Suggestions

7. Code Duplication in Test Helper Functions

Severity: Very Low
Location: test/e2e/claim_reentrancy_test.go, test/e2e/internal_claims_test.go

Similar patterns for encoding ABI tuples and managing claim parameters appear multiple times.

Recommendation: Consider extracting common test utilities into a shared package if more tests are added in the future.

8. Magic Numbers in Test Amounts

Severity: Very Low
Location: Multiple test files

var bridgeCoreMessageAmount = big.NewInt(1e14) // 0.0001 ETH
var bridgeCoreNativeAmount = big.NewInt(1e17) // 0.1 ETH

While commented, these could be more descriptive constant names.

Recommendation: Use more semantic names like SmallTestAmount and LargeTestAmount with comments explaining their purpose (e.g., "large enough to make fees negligible").


Overall Assessment

This is a high-quality migration effort with:

  • ✅ Excellent documentation and planning (MIGRATION_PLAN.md, ENVS_INTEGRATION_PLAN.md)
  • ✅ Comprehensive test coverage maintained (all 9 bats files migrated)
  • ✅ Proper error handling and cleanup patterns
  • ✅ Good use of Go testing patterns (testify/require)
  • ✅ Important production bug fixes included
  • ✅ Well-structured code with clear separation of concerns

Main concerns:

  • 🔴 PR size makes thorough review challenging - consider splitting
  • 🔴 Production bug fixes should be extracted and reviewed separately
  • 🟡 Some test timeouts seem excessive and may hide performance issues

Recommendation: Approve with conditions

  1. Ensure multiple experienced reviewers examine different subsystems
  2. Consider extracting production bug fixes for independent review and backporting
  3. Address the timeout investigation suggestion before merge

The migration work itself is solid and represents significant engineering effort. The test infrastructure is well-designed and extensible. The main risk is the PR size making it difficult to catch subtle issues.
