The wallet switcher couldn't tell a BIP39 seed-phrase wallet from a legacy /
raw-entropy HD wallet without loading it, so non-active rows fell back to bare
HD-record presence — which mislabeled every HD wallet as "Seed phrase".
The distinction is actually on disk: the daemon serializes CHDChain with an
fMnemonicSeed bool (VERSION_HD_MNEMONIC=3, byte offset 52), and the hdchain
record stays plaintext even in an encrypted wallet. Read it directly:
- wallet_file_probe.h: hdChainMnemonicFlag() decodes the flag from the hdchain
value (1 mnemonic / 2 no-phrase / 0 undecidable); WalletBtreeStats.mnemonicSeed
surfaces it from the tier-2 btree walk.
- wallets_dialog.h: the badge prefers runtime z_exportmnemonic for the active
wallet, then the on-disk flag, then HD-record presence — so every row is
classified correctly (or honestly shows "?" when the flag can't be read, e.g.
the tier-1 byte-scan fallback).
- tests: decode-level cases (v3 set/clear, v1/v2, truncated, garbage version)
plus an end-to-end btree walk asserting mnemonicSeed.
Offset math + badge logic adversarially verified against the daemon source.

Parse the earliest keymeta nCreateTime out of the wallet.dat btree (the daemon's
"wallet birthday") and surface it in each row's metadata line ("created Aug 2025").
Add a sort control above the list — Date created / Address count / Transaction
count / Wallet size, with an ascending/descending toggle (descending default:
newest / most / largest first). Sorting reorders a display-index array
(s_order) rather than s_rows, so the async, index-aligned probe batch is
untouched; sort keys read a single frame-consistent snapshot of the probe
results. Address count prefers the authoritative cached index value, else the
btree key count.

parseWalletBtree() walks the wallet.dat Berkeley DB btree directly (no libdb, no
daemon): validate the metapage magic, follow the "main" sub-database (its pgno is
stored big-endian in the master map), traverse internal/leaf pages, and tally
records by their length-prefixed type name — transparent + shielded spendable
keys, address-book, and tx count, plus exact encryption/seed flags. Every offset
is bounds-checked, pages are deduped at push time (stack stays O(npages)), and a
visited-set + page/key caps make it safe on a corrupt/adversarial imported file;
files using DB_CHKSUM/DB_ENCRYPT (which shift the page layout) are rejected so the
byte-scan fallback runs instead.
The async probe now uses this as the primary path (exact badges + counts), falling
back to the byte-scan only when the btree can't be fully parsed. The wallets list
shows "N keys · M txs" for probed rows (labeled "keys", not "addresses", since the
count includes change keys the daemon's address list omits). Validated read-only
against real wallets (counts cross-checked; enc/seed match the byte-scan) and a
hand-built minimal btree fixture in the unit suite.

Search user-added wallet folders RECURSIVELY (bounded: depth/hit/visit caps,
skip_permission_denied, no symlink-follow, node-junk + node-subtree pruning);
the datadir stays top-level. r.dir is each file's real parent so Open/import
resolve subdir wallets. Auto-suffix the import destination on a name collision.
Add util/wallet_file_probe.h: read encryption/seed/shielded flags straight off
a wallet.dat WITHOUT loading it — validate the Berkeley DB btree magic, then a
bounded streaming byte-scan for the length-prefixed record markers the daemon
writes (mkey -> encrypted; hdseed/hdchain -> seed/HD; zkey/sapzkey -> shielded).
Reads no key material. The Wallets dialog shows Encrypted / Seed / Legacy badges,
plus an Unknown badge when a large file couldn't be fully scanned (so absence of
a lock never falsely reads as unencrypted). Unit-tested + validated read-only
against real wallets.
