Litecoin.watch beginner address and order research, release 2026-10-03-v1.
Two different evidence types: controlled Core address parsing and synthetic order arithmetic. Never combine them into a claim about actual trading or recovered funds.

ADDRESS EXPERIMENT
Test time: 2026-10-03T08:16:57.730520+00:00. Core 0.21.5.8. Binary SHA-256: 63fb440cdc5e2e7d46144b8e3a47dab4725fa9c056a77b8b12b11854504f4838.
18 deterministic synthetic fixtures, 36 validateaddress RPC observations, 46 executable assertions. Fresh disconnected mainnet-mode and regtest nodes: zero peers, height zero, wallets disabled. Connection/listening/DNS discovery disabled; dbcache bounded at 32 MiB per temporary process. No live-chain synchronization, wallet creation, signing keys, transfer, service credit, MWEB or recovery test.
Mainnet here identifies decoder parameters, not a synchronized mainnet observation. Synthetic destinations are hash payloads, not receiving addresses anyone has demonstrated control over. NEVER SEND FUNDS TO A FIXTURE.
Historical P2SH version 5 and modern LTC version 50 fixtures encode the same synthetic script hash and produce identical Core output scripts. Bitcoin's historical version-5 definition is separately source-backed; no Bitcoin Core executable was tested. A passing address does not choose the sending chain, establish ownership or guarantee service credit.
To rerun with your verified Core binary, save address-checks.py.txt as address-checks.py:
python address-checks.py /absolute/path/to/litecoind /absolute/path/to/new-output-directory
The script uses only the Python standard library, starts fresh temporary processes and stops them at completion. It must never be pointed at an existing node data directory. The recorded binary hash identifies our Linux build, not every operating-system package.

ORDER MODEL
12 deterministic scenarios, two FIFO queue events, 78 assertions. All prices, sizes, maker/taker fees, queue priority and later fills are synthetic. Declared asks: 60.00 x 0.50 LTC, 60.10 x 1.00 LTC, 60.40 x 1.50 LTC. A separate queue example has 2 LTC ahead of our own 2 LTC at 59.90, followed by hypothetical incoming sells of 1 and 1.5 LTC.
Maker fee 0.10%, taker fee 0.20%, charged in EUR. These are NOT provider fee quotes. Decimal arithmetic retains analytical precision; actual exchange increments, fee rounding and settlement precision are not reproduced. A reserve for an open remainder equals remaining quantity x limit x (1+taker fraction), an explicit conservative teaching assumption, not an observed balance.
The post-only rule rejects a crossing order; it does not model repricing. FOK prechecks available declared depth; IOC cancels its unfilled portion; GTC leaves a remainder open. Market-five depth_exhausted walks only the bounded fixture, NOT an exchange's real market-order response. Mixed-role completion requires a separately assumed later seller and no prior order at the limit.
Excluded: actual exchange engine, latency, hidden orders, priority changes, minimums/increments, fee tiers, self-trade prevention, funds checks, price protection, eligibility, deposits and withdrawals. No trading recommendation, fill probability, ranking, live quote or forecast.
Save order-model.py.txt as order-model.py:
python order-model.py /absolute/path/to/new-output-directory
The generated order-results.json should match this frozen model exactly. Do not overwrite your archived copy when exploring new inputs.

OFFLINE PACKAGE CHECK
Keep original .py.txt names and JSON files together. Save verify-package.py.txt as verify-package.py:
python verify-package.py /absolute/path/to/package-directory
This reconstructs deterministic addresses, checks consistency of recorded Core outcomes and exact script equality, and recalculates the model. It does NOT perform fresh Core validation, prove ownership, recover funds, observe orders or audit a venue. Run the Core collector separately for new RPC evidence.

DOWNLOADS AND CHECKSUMS
address-checks.csv: 36 recorded checks; addresses are explicitly labeled do_not_send. order-cases.csv: 12 declared alternative scenarios; never sum them as real trades. JSON exports preserve scopes, individual outputs/fills and assertions. Blank TXT checklists are for private local use and contain no credential fields. Original SVGs are explanatory diagrams, not screenshots or exchange data.
Source-records.json records primary URLs and capture hashes checked 3 October 2026. Full third-party source pages are not redistributed. SHA256SUMS.txt covers content except itself and archive files; the ZIP contains that checksum file. archive-sha256.txt separately identifies the ZIP.
