Litecoin.watch editorial batch, 22 October 2026.
Two new guides: coinbase maturity; txid/wtxid evidence.
Five corrected guides: upgrades, development, privacy, transaction states and block time.
AI-assisted editorial/source and calculation checks, not an independent security audit.

maturity-boundaries.csv encodes synthetic heights under Core 0.21.5.8 constants,
input-validation height differences and wallet GetBlocksToMaturity formulas.
No new mining or spend test. A passing maturity condition is not a valid-spend verdict.
block-interval-model.csv is a stationary analytical model, not observed network data.
The separate archived weekly observation study is linked in the article, with unresolved
outcomes preserved. No new confirmation sample or timing guarantee is claimed.

transaction-id-cases.json uses one original signed candidate from:
https://litecoin.watch/uploads/research/practical-20260930/batching/batch-results.json
Original scope: isolated Core 0.21.5.8 regtest, payment candidates not broadcast/mined.
The new offline script cross-checks all 164 archived txids and weights, then alters
one witness byte and one output-value byte separately in the first candidate.
Altered data is NOT VALIDATED and MUST NOT BE BROADCAST.
The script does not verify signatures, UTXO state, policy or live inclusion.
It only supports ordinary transparent SegWit serialization, not arbitrary MWEB.

Save each .py.txt script as a .py file and run with Python 3 standard library.
Timing script needs no argument. Identifier script takes the local original archive.
Scripts have no network, wallet, broadcast or file-writing operations.
Worksheets contain no credential fields; keep filled records private.
feature-evidence-ledger.csv distinguishes activation, lock-in and deployment start.
Two original explanatory cover diagrams are illustration, not screenshots or measurements.
SHA256SUMS.txt identifies the other files in this folder.
Original code/worksheets/artwork MIT; original calculated exports CC0-1.0.
