hal speaks pver 5: preimages prove their size, and fees round up as one

2026-08-05T19:24:03Z

0.6.0 servers require the new hashlock clauses (OP_SIZE 32 guard) for Lightning and rounds. New policies/transitions carry the v1 scripts and type bytes; _v0 variants keep old vtxos reconstructing and exiting. The retired third-party HTLC policy is dropped (upstream took 0x08).

Ark: recover from stale vtxo state

2026-07-05T02:29:08Z

Match captaind's actual 'not spendable' error so a crashed or foreign spend fails the action instead of retrying forever, and reconcile locally-spendable vtxos against the server (GetVtxoStatus + ownership attestation) when an ark address lands in the send form. boardFee now treats absent proto3 fee fields as zero (Second's signet boards free).

Ark: native-JS protocol client + persistent ArkManager

2026-07-03T21:46:36Z

Speaks Second's bark/captaind Ark protocol directly from the browser — gRPC-web over fetch with hand-rolled protobuf, no wasm, no new deps (crypto via the existing @scure/@noble stack incl. btc-signer's BIP-327 musig2 module). src/ark: - proto.js transport, ark address codec, mailbox blinding/auth, VTXO ProtocolEncoding v2 decode - send.js arkoor send: checkpoint+arkoor txs, BIP-341 sighashes, MuSig2 cosign ceremony, signed-VTXO assembly - board.js onchain -> ark: funding taproot, exit-tx cosign - refresh.js delegated round (hArk): participation, tx-chain reconstruction, hash-locked leaf cosign, forfeit swap - validate.js receive-side verification: chain must land on the vtxo point, anchor checked onchain, every transition sig verified - manager.js persistent wallet layer: storage-checkpointed step-machine actions (send/board/refresh) that survive crashes, mailbox sync with validation, multi-input consolidation refresh tools/ark: end-to-end regtest tests (receive, send, board, refresh, manager incl. crash-mid-send + resume), all passing against captaind with the bark CLI as counterparty.
