Add design for HTLC and multisig transaction type support needed for
hardfork 1 activation at block 10,080. Covers types, wire, and consensus
changes with TxOutTarget interface refactor.

Move all 21 plan files to docs/plans/completed/ — every phase (0-9) is
implemented. Expand history.md with full writeups for the Difficulty
Computation, V2+ Zarcanum Consensus, and TUI Dashboard sections that
were previously just bullet points.

Three-part design: NLSAG signature verification, full RPC sync to tip,
and P2P block sync via REQUEST_CHAIN / REQUEST_GET_OBJECTS. 13-task
implementation plan with TDD steps.

Fix three bugs in the v2+ wire format and add complete variant tag handlers
for Zarcanum proof and signature structures. Verified byte-identical
round-trip against a real post-HF4 coinbase transaction from testnet block
101 (1323 bytes, tx hash 543bc3c2...3b61e0).
Bugs fixed:
- V2 suffix order was attachment+proofs, corrected to attachment+signatures+proofs
- TransactionHash was hashing full blob, corrected to prefix-only (matching C++)
- tagSignedParts was reading 4 fixed bytes, corrected to two varints
New: TxInputZC type, SignaturesRaw field, tagZarcanumTxDataV1 handler,
proof tags 46-48, signature tags 42-45, crypto blob readers for BPP/BPPE/
BGE/CLSAG GGX/GGXXG/aggregation proof/double Schnorr structures.

Add cn_bpp_verify for Bulletproofs++ (1 delta, bpp_crypto_trait_ZC_out)
used by zc_outs_range_proof in post-HF4 transactions. Distinguish from
cn_bppe_verify (2 deltas, bpp_crypto_trait_Zarcanum) used for Zarcanum
PoS proofs.
Key changes:
- Add deserialise_bpp() and cn_bpp_verify() to bridge.cpp
- Add VerifyBPP() Go wrapper in proof.go
- Wire BPPE and BGE stubs into real C++ verify functions
- Add try/catch to all proof verifiers (C++ throws on invalid points)
- Add nil/empty input guards to all Go proof functions
- Test with real BPP proof from testnet block 101 coinbase tx
The BPP proof from tx 543bc3c2... (first post-HF4 coinbase) verifies
successfully through the full CGo pipeline, confirming wire format
deserialisation matches the C++ daemon output.

Original founding document for the Zano protocol extensions.
Contains raw math for return addresses, key derivation, shared

CGo bridge to vendored upstream C++ crypto library following the MLX
pattern. Thin C API (bridge.h) as the stable contract between Go and
C++. Provenance tracking for easy upstream Zano updates.

Add consensus-critical binary serialisation for blocks and transactions,
verified by computing the testnet genesis block hash and matching the C++
daemon output (cb9d5455...4963). Fixes Phase 0 type mismatches (variant
tags, field widths, missing fields) and adds encoder/decoder, tree hash,
and block/transaction hashing.
Key discovery: CryptoNote's get_object_hash(blobdata) prepends
varint(length) before hashing, so BlockHash = Keccak256(varint(len) || blob).
