277     * This map originally just held P2SH redeemScripts, and was used by wallet
278     * code to look up script ids referenced in "OP_HASH160 <script id>
279     * OP_EQUAL" P2SH outputs. Later in 605e8473a7d it was extended to hold
280     * P2WSH witnessScripts as well, and used to look up nested scripts
281     * referenced in "OP_0 <script hash>" P2WSH outputs. Later in commits
282     * f4691ab3a9d and 248f3a76a82, it was extended once again to hold segwit
283     * "OP_0 <key or script hash>" scriptPubKeys, in order to give the wallet a
284     * way to distinguish between segwit outputs that it generated addresses for
285     * and wanted to receive payments from, and segwit outputs that it never
286     * generated addresses for, but it could spend just because of having keys.
287     * (Before segwit activation it was also important to not treat segwit
288     * outputs to arbitrary wallet keys as payments, because these could be
289     * spent by anyone without even needing to sign with the keys.)
290     *
291     * Some of the scripts stored in mapScripts are memory-only and
292     * intentionally not saved to disk. Specifically, scripts added by
293     * ImplicitlyLearnRelatedKeyScripts(pubkey) calls are not written to disk so
294     * future wallet code can have flexibility to be more selective about what
295     * transaction outputs it recognizes as payments, instead of having to treat
296     * all outputs spending to keys it knows as payments. By contrast,
297     * mapScripts entries added by AddCScript(script),
298     * LearnRelatedScripts(pubkey, type), and LearnAllRelatedScripts(pubkey)
299     * calls are saved because they are all intentionally used to receive
300     * payments.
301     *
302     * The FillableSigningProvider::mapScripts script map should not be confused
303     * with the wallet::LegacyDataSPKM::setWatchOnly script set. The two collections
304     * can hold the same scripts, but they serve different purposes. The
305     * setWatchOnly script set is intended to expand the set of outputs the
306     * wallet considers payments. Every output with a script it contains is
307     * considered to belong to the wallet, regardless of whether the script is
308     * solvable or signable. By contrast, the scripts in mapScripts are only
309     * used for solving, and to restrict which outputs are considered payments
310     * by the wallet. An output with a script in mapScripts, unlike
311     * setWatchOnly, is not automatically considered to belong to the wallet if
312     * it can't be solved and signed for.
