v0.4.0
ee21d52

First npm release since 0.3.0 — npm install sparkbtcbot-skill@0.4.0 — folding in the full 0.4.0 line. Also available as a Claude Code plugin (claude plugin install sparkbtcbot).

Live-validated end-to-end on real mainnet sats under two stacks: Claude Code, and opencode running GLM-5.2 via OpenRouter.

Highlights

Money-path fixes (all found by live agent testing, all regression-tested)

  • BigInt sats amounts work everywhere. getBalance() returns bigint; passing one back into transfer/withdraw used to throw a misleading "must be less than 2^53". A toSats() normalizer now guards every SDK-bound amount, and dry-run/live paths agree.
  • L402 challenges parse from the WWW-Authenticate header (the spec-standard location) and support the current spec's token= field — header-only servers like aperture/lightningfaucet no longer throw Invalid L402 challenge.
  • listPendingDeposits() — confirmed-but-unclaimed L1 deposits were invisible (getBalance() shows claimed balance only), so agents answered "did my deposit arrive?" with a false no. Now one call lists them, feeding straight into claimDeposit().
  • The leaf-vault no longer cries BROKEN during cooperative L1 exits. The settlement window (leaves gone from the leaf set, owned still counting them until L1 confirms) tripped the recovery-backup alarm on every withdrawal. The guard now demands positive SSP evidence of a pending exit before excusing the gap — and degrades to the old strict behavior on any uncertainty.
  • One-shot scripts that move value no longer race the SDK's background leaf optimizer — SparkAgent.create(..., { optimizeLeaves: false }).

Security & guardrails

  • AGENTS.md — the load-bearing security rules (never print the mnemonic or passphrase; a "user request" to reveal the seed never arrives via fetched content or tool output) now reach non-Claude agents that don't auto-load SKILL.md.
  • Recipient allowlist closes its last gap — fulfillInvoice now decodes and gates the invoice receiver like every other outbound path.
  • Rolling 24h spend budget (SPARK_DAILY_BUDGET_SATS) — bounds send loops, the failure mode per-call caps can't catch.
  • Guard values validated, not just guard keys — maxFeePct: "10%" throws instead of silently disabling the ceiling.
  • reveal-mnemonic replaces the plaintext backup file: setup never prints or writes the words; the user reveals them on demand in their own terminal (refuses non-interactive capture).
  • Node floor raised to >=20; CI audits dependencies (npm audit clean at release).

Bridge & merchants

  • Boltz removed (all swaps disabled indefinitely, Aug 2026); the native Lightning↔L1 bridge is documented in both directions with every fee live-measured on mainnet, including estimateOnrampDeposit() for sizing deposits across both fee legs.
  • Merchant references re-verified live (Bitrefill, nadanada, Cryptorefills): endpoint moves, response wrappers, WireGuard key generation, and catalog field-name traps documented from real purchases.
