The spec is the contract; where this text and the spec differ, the spec wins. Report any conflict instead of guessing.\n\nBuild Job 2: the on-chain verifier for imd-beacon rounds. Do not deploy anything.\n\nFiles to produce:\n- src/BeaconVerifier.sol: immutable network descriptor and group key, installed once at a verified genesis and never changeable afterwards. It verifies one round's BLS12-381 group signature with the EIP-2537 precompiles and stores R(r) = SHA256(compressed G1 signature) as in §4.3.\n- src/interfaces/IBeacon.sol: already drafted from §8.2; freeze the final ABI and adjust it if needed (§8.2, §8.3).\n- Reviewed BLS, hash-to-curve and encoding libraries under lib/. Vendor them as ordinary files with licence notices. If you adapt randa-mu/bls-solidity, record the source revision and review every line you keep. Add strict canonical-encoding checks it lacks.\n- test/contracts/BeaconVerifier.t.sol, test/vectors/bls12.json, docs/verification-gas.md, and a Makefile target that runs the whole suite offline.\n\nCryptography, exactly as specified in §4.3:\n- Message M(r) = \"IMD_BEACON_ROUND_V1\" || networkId || U64BE(E(r)) || U64BE(r). Reject r = 0, overflow, epoch mismatch and the wrong network.\n- RFC 9380 BLS12381G1_XMD:SHA-256_SSWU_RO_ with the DST BLS_SIG_BLS12381G1_XMD:SHA-256_SSWU_RO_NUL_. Compute expand_message_xmd on-chain, then map two field elements with the EIP-2537 MAP_FP_TO_G1 precompile and add them. Never implement H(M) = hash(M)·G1.\n- Signatures in G1, group key in G2. Submit form is 96-byte uncompressed x || y with canonical 48-byte big-endian coordinates. Rebuild the standard 48-byte compressed encoding internally; that is the only input to the output hash.\n- Reject infinity, non-canonical field elements, wrong lengths, off-curve and non-subgroup points, wrong G2 coefficient order and extra bytes. Every precompile call must succeed with the exact return length and expected value; empty returndata from a missing precompile is a failure.\n\nRequired tests (names from §10.3): test_Rfc9380Vectors, test_IndependentBlsVectors, test_CanonicalCompressionHash, test_RejectInfinity, test_RejectNonSubgroup, test_RejectNonCanonicalField, test_RejectMalformedLength, test_RejectWrongNetworkEpochRound, test_RejectMissingPrecompile, test_OutOfOrderRound, test_NoDuplicateFee, test_ZeroRandomnessAvailability (mock allowed only for this one), testFuzz_EncodingCannotChangeOutput (at least 10,000 runs) and testFuzz_ModifiedSignatureFails.\n- Vectors must come from RFC 9380 plus an independent implementation (blst or another reviewed BLS12-381 library) run offline. Do not check the Solidity code only against itself. Include one deterministic threshold fixture and at least 100 independent valid signatures, with generation provenance recorded in test/vectors. Test keys are test-only and labelled non-production.\n\nGas budgets: testGas_VerifySingleRound at most 170,000 execution gas; testGas_SubmitFirstWrite at most 250,000 receipt gas, including intrinsic and calldata, without rewards. Record the measured numbers, storage writes and compiler profile in docs/verification-gas.md. If a budget cannot be met, report the measurement and the cause. Do not weaken a check to fit.\n\nConstraints: foundry.toml is fixed (workers cannot edit it): solc 0.8.30, EVM prague, bytecode_hash none, ffi off, read access to test/vectors only, so commit generated vectors as files and set the 10,000-run fuzz count with inline forge-config comments. Contracts go under src/ (IMD convention; SPEC §10.2 says contracts/). No admin setter for randomness, group key or config after genesis; early-round submission reverts; anyone may submit a valid round; a duplicate submission never pays twice. No network access needed to build or test. No private keys or real addresses in the tree. Leave rewards (Job 7), the registry (Job 3) and deployment (Job 9) out of scope. Update docs/SPEC.md only if you find an error in it, and explain the change in the pull request.","parentJobId":null,"planHash":"24aa7ae7c3f3324d03edd6fce43e462113243d7fc35a9b4f78ec9b263e5575bf","previousHash":"0000000000000000000000000000000000000000000000000000000000000000","projectId":"044913fb-4465-4c2c-bfda-2d75d43a9659","publication":{"commit":null,"deliveredAt":null,"repoUrl":"https://github.com/identity-md-launches/launch-2586-repository-https-github-com-bradymck-imd"},"receiptIdentity":{"adapter":"0xde152afb7db5373f34876e1499fbd893a82dd336","chainId":1,"collection":"0x0000ec93127baa929e58e97dd0095a2bfb38ec1d","registry":"0x8004a169fb4a3325136eb29fa0ceb6d2e539a432"},"registry":"0xb6d0a187b050fa5bb0b87033a203f37becf4a775","research":[],"schema":"identitymd-work-v1","signals":[{"agentId":"52606","feedbackHash":"eccd43b79e73350e1a88123fe6e07e7cd3c68aee7832baf9de511cd62dc3c252","nodeKey":"adapt_contract_project","submissionHash":"473bfe01e89bcc1f5f991fba1a8bef1e4561f3c417d96dffb92b54672b444f0a","tag1":"verification:checks","tag2":"acceptance-v2","value":1},{"agentId":"51083","feedbackHash":"b83831a6f07387cde7caaf374b2e023fe3e01f69d9a2ab3ecfbc443b6e802fb1","nodeKey":"audit_imported_code","submissionHash":"8870670cac01260275d50f965f3ae113761aa032dee846323992f136b8b5cac7","tag1":"review:submission","tag2":"acceptance-v2","value":1}],"site":null,"snapshotHash":"b5d30298235448929398213aefd5f63d6434ad959924554f9f9c3d8a0a44ccc5","state":"blocked","submissions":[{"artifacts":[],"attempt":1,"bundleHash":null,"device":"3c9b660ee1938912","findings":[],"hash":"41045efa667d4b41aebeeb1b369c40cbb282f68b92e3f8ee985395fc7d1a4b1d","nodeId":"571e4aa4-9890-4cd2-a607-8b075e7d8470","outcome":"failed","summary":"needs input: BeaconVerifier's constructor (bytes32 networkId, uint64 genesisTime, GroupKeyWords key, address epochAuthority) needs four launch values that are not in the brief, the spec or the accepted tree, and that cannot be $owner or a placeholder: (1) networkId = keccak256(\"IMD_BEACON_NETWORK_V1\" || configHash) of the production network config (SPEC §4.1), non-zero; (2) genesisTime T0 in Unix seconds, non-zero; (3) the group public key from the DKG ceremony (Job 4), given as the 256-byte EIP-2537 affine G2 encoding pad64(x.c0)||pad64(x.c1)||pad64(y.c0)||pad64(y.c1), i.e. eight bytes32 words.

From a clean build, `forge build` and `forge test` pass offline with the verifier's fuzz seed: 19 tests, 0 failures, including the 10,000-run encoding fuzz. Both gas budgets are met.\n\n**What was built**\n\n- `src/BeaconVerifier.sol`: immutable descriptor and G2 group key set in a nonpayable constructor with 11 static words and no owner or setter. The constructor validates the key via G2MSM and runs a known-answer self-test of every precompile the verifier uses, so a missing precompile fails deployment. It calls no other contract, so it runs on the launch's empty chain.\n- `src/bls/BLS12381.sol` and `src/bls/HashToCurveG1.sol`: in-tree libraries with canonical-field, infinity, length and exact-return-length checks, RFC 9380 expand_message_xmd on chain, MAP_FP_TO_G1 twice plus G1ADD, and a pairing check against a constant negated G2 generator. Every precompile call forwards bounded gas, which SPEC §4.4 requires and which a failing non-subgroup input otherwise exploited to burn the caller's whole budget.\n- `src/interfaces/IBeacon.sol` frozen: `submit` returns `firstWrite`, the event carries the 48-byte compressed signature, and descriptor getters were added. `IEpochAuthority.sol` is new.\n- Tests, vectors from noble-curves 2.4.0 plus RFC 9380 appendix vectors, a 3-of-4 threshold fixture, `docs/verification-gas.md`, a Makefile, ADAPTATION.md and README updates.\n\n**Gas measured** (execution includes CALL overhead, so on-chain is slightly lower)\n\n| Test | Result | Budget |\n|---|---|---|\n| verify single round | 135,374 execution | 170,000 |\n| submit first write, epoch 0 | 230,401 receipt | 250,000 |\n| submit first write with epoch gate | 235,946 receipt | 250,000 |\n\n**Deviations you should know about**\n\n- Libraries are not under `lib/`. The task rules forbid touching `lib/` and `remappings.txt`, so the BLS libraries are in `src/bls/` and forge-std in `test/forge-std/` with relative imports. This conflicts with the brief and SPEC §10.2 and is recorded in ADAPTATION.md.\n- The epoch gate conflict (audit finding f8ef8bff) was resolved by an immutable `epochAuthority` constructor argument consulted by `submit` for epochs after genesis. Epoch 0 is authorized by genesis itself, and `verify` has no gate. If you want the gate in a Job 3 wrapper instead, the change is dropping one argument and one call.\n- `docs/SPEC.md` line 128 now says \"receipt budget\" instead of \"execution budget\" (audit finding c871e483). No other spec text changed.\n\nAll five audit findings reproduced and are fixed with tests. The launch manifest will need real values for the group key and the epoch authority, which do not exist until Jobs 3 and 4; neither is an owner, and neither should be filled with a stand-in. `make` is not installed on this machine, so I ran the Makefile recipe's command directly.","treeHash":"76d4261d9750a77b78a17000c50be758a8cd83e6","usage":{"cachedInputTokens":4294336,"inputTokens":1090,"model":"claude-fable-5-1","outputTokens":99087,"runtime":"claude","turns":52,"wallClockMs":1268125}},{"artifacts":[],"attempt":2,"bundleHash":null,"device":"9e17b97b8ac7c97a","findings":[],"hash":"6b9aca9a35d8fc3ec47e68d20b9af483bd9235e3a108d999308fa6929cb35d9f","nodeId":"571e4aa4-9890-4cd2-a607-8b075e7d8470","outcome":"failed","summary":"needs input: BeaconVerifier's four constructor values for Sepolia.

The implementer should treat 250k as receipt gas (three of four mentions, and the brief) and fix the wording at line 128 in the Job 2 PR.","line":128,"path":"docs/SPEC.md","reproduction":"A verifier whose submit first-write measures 240,000 execution gas passes under the line-128 wording and fails under R6/§10.3 (240,000 + 21,000 intrinsic + ~1,700 calldata ≈ 262,700 receipt gas > 250,000).

There is no state-changing code, no owner role, no value flow and no forbidden opcode to assess. The interface compiles under the pinned solc 0.8.30 and Prague profile. No critical or high defects exist in this tree, so no proof tests were attached.\n\n**Findings written to `.imd-findings.json`** (five entries, each with path, line, exact snippet and reproduction):\n\n- **Low. Submit NatSpec omits the authorized-epoch gate.** SPEC §8.2 requires `submit` to check an authorized epoch as well as the release time. The draft documents only the timestamp, and the ABI carries no epoch input, so the brief's \"reject epoch mismatch\" has nothing to act on. This is a spec-versus-brief conflict, since the registry the gate depends on is out of Job 2 scope. Reproduction: a valid signature for round 2881 with no epoch-1 certificate is accepted as documented, but must revert per spec.\n- **Low. No descriptor getters.** Consumers need networkId, T0 and the period to pick a target round and compute W(counter) under §8.3. None is readable through the interface, so a consumer must hardcode descriptor values.\n- **Info. Event signature encoding not frozen.** The event's `bytes signature` could be the 96-byte affine input or the 48-byte compressed hash preimage. An indexer recomputing R from the event disagrees with one of the two conforming choices. Recommend the compressed form.\n- **Low. No test can compile.** `lib/` holds only a `.gitkeep`. Any test importing `forge-std/Test.sol` fails with a file-not-found error, which I confirmed with a scratch test and then removed. The spec requires offline, vendored dependencies, so forge-std must be committed as plain files.\n- **Info. Spec gas wording conflict.** SPEC line 128 calls the 250k budget \"execution\" gas while R6, §4.4 and §10.3 call it receipt gas including intrinsic and calldata. The readings differ by roughly 23,000 gas and can flip the result of `testGas_SubmitFirstWrite`.\n\n**For the adapter.** The interface is close to §8.2 but should be frozen with the epoch-gate decision made explicit, descriptor getters added, the event encoding named, and forge-std vendored before any of the fourteen required tests or the gas budgets can be exercised. The rest of Job 2's acceptance list cannot be audited until the verifier and vectors exist.","treeHash":null,"usage":{"cachedInputTokens":507441,"inputTokens":226,"model":"claude-fable-5-1","outputTokens":16019,"runtime":"claude","turns":18,"wallClockMs":256040}}],"verification":[{"checks":[{"durationMs":2106,"exitCode":0,"name":"build","output":"Compiling 38 files with Solc 0.8.30\nSolc 0.8.30 finished in 2.02s\nCompiler run successful!\n","passed":true},{"durationMs":960,"exitCode":0,"name":"test","output":"No files changed, compilation skipped\n\nRan 19 tests for test/contracts/BeaconVerifier.t.sol:BeaconVerifierTest\n[PASS] testFuzz_EncodingCannotChangeOutput(uint8,uint8,uint8,uint8,uint8) (runs: 10000, μ: 144145, ~: 169837)\n[PASS] testFuzz_ModifiedSignatureFails(uint8,uint256,bool,uint64,uint8) (runs: 2000, μ: 246146, ~: 308089)\n[PASS] testGas_SubmitFirstWrite() (gas: 331648)\nLogs:\n  case: epoch 0, fresh availability word\n  calldata bytes: 196\n  calldata gas: 2008\n  execution gas (incl.
