Verify the mined block's scriptSig contains "kamado" branding and
btcsig tag, check consensus size limits, and tail bitcoind's
-debug=validation log to show internal block acceptance.
Validates the end-to-end path log tailer → aggregator → bitcoind
enrichment → /api/blocks without a real miner:
1. Starts a fresh bitcoind in regtest mode (temp datadir, port 18443)
2. Mines 102 blocks so the coinbase is mature and the target block
is live in bitcoind's chain
3. Starts kamado-api wired to regtest bitcoind (ckpool socket dir
points at an empty dir — connect failures are expected and
non-fatal)
4. Appends "Solved and confirmed block <height>" to the ckpool log
file; the log tailer picks it up and calls getblockhash to enrich
5. Polls /api/blocks until the block appears (up to 30 s)
6. Verifies the hash is a 64-char hex string and matches what bitcoind
returns for getblockhash at that height
The binary is auto-built from source if go is in PATH; set KAMADO_BIN
to skip the build step. All processes and temp files are cleaned up on
exit via trap.
