the gap limit was 1000, hardcoded, with the comment noting that raising it costs
node CPU and not correctness — and no way to raise it. it is the one thing about
a scan only the owner can know: how many addresses their old wallet handed out
and never had paid. RescanOptions threads from the POST body through the backend
and the source to utxos/scan, capped at 100k because past that the scan takes
longer than anyone waits. the card gets a "search depth" field beside the button,
blank meaning the default.
deleting a wallet with no seed took one unconfirmed request. the dialog asked for
the wallet's name and then threw the answer away, so the check existed only for
whoever went through the dialog — a node wallet still holds the credential, the
labels and the freezes. confirmName now travels with the request and the route
enforces it. a bodyless DELETE is told which field is missing rather than that
its JSON did not parse.

four wallet defects, none urgent, all cheap:
selectCoins let an explicit coin-control pick override a freeze. naming an
outpoint now overrides only the confirmed-only default; frozen is absolute.
balances counted frozen coins in onchainConfirmed, so Send showed a figure a
max-value spend could not reach. Balances gains onchainFrozen — a component of
confirmed, not a deduction — filled at the route layer, because freezing is
Officer policy in Postgres and no backend can see it. The route only reads utxos
when something is actually frozen. Send subtracts it under "Spendable";
Overview lists it beside unconfirmed.
a rescan in flight upstream was invisible after a sidecar restart, and a second
POST would have queued behind it (scantxoutset is single-threaded node-wide).
adoptRescan polls an existing NBXplorer scan instead of starting one, and the
GET route falls back to it when local state is gone.
the per-variant scan deadline counted queue time, so a variant that sat behind
another wallet's scan timed out without ever having run. the deadline now
refreshes while the status reads Queued.

two holes found auditing the wallet sidecar after the frozen-utxo fix.
the brute-force backoff lived inside UnlockSession.unlock alone, so /unlock capped
at five guesses a minute while export-seed — the one endpoint that returns the words
in the clear — took unlimited ones. every passphrase check now goes through the same
guard. verifyPassphrase rethrows LOCKED_OUT rather than folding it into `false`, so a
caller can tell "wrong" from "stop".
nextUnused advanced its mark on every issuance, paid or not, so a run of unpaid
addresses walked it past the end of the window the next scan covers; a payment there
would never be found again, and esplora has no rescan to go looking. sources now
declare how far past a scan's last index they can still see, and issuance clamps to
it — re-offering a virgin address rather than handing out one that could lose money.

freezing a coin promised it would not be spent, and the promise only
held when the caller named outpoints explicitly. an ordinary send picked
its own inputs from a snapshot in which every utxo said frozen: false —
the chain has no idea what officer froze — so selectCoins, which has
always filtered on that flag, never saw one set. sendAll was the worst
case: "send everything" swept the frozen coin too.
the frozen list now travels with the request, set by the route and
overwritten if a caller supplies one. it can only ever restrict what is
spendable, so smuggling a value in gains nothing. the backend still
reads no officer table.
three tests pin it, including a control that sends successfully once the
coin is unfrozen — without it the other two would pass on a wallet that
could not spend at all.

the route typed its body as {name, defaultBip, config} and passed the
parsed object straight to updateWallet, which also accepted sealedSeed
for the passphrase change. a TypeScript annotation strips nothing at
runtime, so any authenticated caller could send a sealedSeed key and
overwrite the encrypted seed — no passphrase, no unlock. encryptSecret
encrypts nonsense happily, so the damage would have surfaced at the next
unlock, not at the write.
updateWallet can no longer touch the seed at all; resealing moves to
replaceSealedSeed, whose only caller has already proved knowledge of the
old passphrase. the route rebuilds its patch field by field as well, so
the next field added there cannot re-open it.
verified against the test wallet: the envelope is byte-identical after
the same request that previously would have replaced it.

the card keyed off `sync.rescan` being null, which is what esplora
reports — and equally what nbxplorer reports before its first scan. so
the guard could not tell "unsupported" from "not yet run" and resolved
it the wrong way: every esplora wallet got a button that 501s.
canRescan carries the distinction explicitly.

registering an xpub only indexes it from that moment on, so an imported
seed with history read as a confident zero: every call succeeded, the
coins were simply absent. scantxoutset walks the node's current utxo set
directly and finds them regardless of when the account was registered.
runs all four script variants sequentially — the funds could be on any
one — and surfaces progress through the existing SyncState channel so
the balance says "scanning" rather than nothing. auto-fires on an
imported mnemonic only; a generated seed has no history to look for.
recovers spendable coins, not spent history.

the key in chain-source-esplora.test.ts was labelled a published test vector and
was not one — it was the owner's live bip84 account xpub, pulled from the
database during an earlier verification and pasted in.
it cannot spend, but it discloses every address that wallet will ever use and
its whole history, permanently. replaced with the bip84 spec's own vector,
derived in the file from the published mnemonic so its provenance can be checked
rather than taken on trust, and pinned by an assertion against the spec's first
address so a future substitution fails loudly.
this does not remove the key from history. that needs a rewrite of 5c38236.

esplora and nbxplorer are now both selectable from wallet settings. the two are
stored as separate service_connections rows but are mutually exclusive: saving
either retires the other, so "which endpoint is in use" is never decided by a
precedence rule.
the nbxplorer probe cross-checks the chain it reports indexing against the
configured network, so pointing a mainnet wallet at a testnet node is refused at
the form rather than discovered later as an unexplained zero balance. esplora
cannot report this, so there is nothing to check there.
/_health now runs the same probe the form does, instead of its own hardcoded
esplora path — the two can no longer disagree about what a working endpoint is.

OnchainBackend depended on the concrete EsploraChain class, so the only wallet
it could ever have was an Esplora-backed one. The seam is now WalletChainSource,
and it is drawn at the scan rather than at the HTTP client: Esplora is
address-level and has to walk the gap limit, NBXplorer is wallet-level and has
no per-address endpoint at all, so there is nothing to share one level down.
The backend keeps the keys and the money — derivation, snapshot cache, coin
selection, PSBT construction, signing — and owns no HTTP. Which indexer answers
is a constructor argument.
Also adds the NBXplorer implementation of the seam, verified end to end against
the owner's own pruned node, and the first tests over any of this: a stub
Esplora drives a real backend through the gap-limit walk, balance summation,
UTXO mapping, transaction scoring and address issuance. Nothing covered the
scan before it was moved, which is the wrong time to have no tests.

The second chain source. Esplora is address-level, so finding a wallet's coins means
walking the gap limit ourselves — 43-160 requests per refresh. NBXplorer is scheme-level:
register the account xpub once and every question after that is a single call. So this is
deliberately NOT an implementation of EsploraChain's interface; there is no per-address
query worth emulating, and emulating one would throw the advantage away.
Verified end to end against the owner's live 2.6.9 instance: status, track, balance,
utxos, transactions, unused address and fee estimates all round-trip, and NBXplorer
derives bc1qwnvlm8... for BIP84 0/0 — byte-identical to what keys.ts derives.
Three things the upstream docs get wrong or leave out, all confirmed by hand:
- single-sig taproot is `-[taproot]`, absent from NBXplorer's own scheme table
- querying an UNTRACKED scheme returns 200 with every figure zeroed, which reads as a
real empty wallet; track() is therefore on every read path, not just at setup
- a rejected broadcast returns 200 with success:false, never an HTTP error

WALLET_ESPLORA_URL was the one wallet setting an owner actually has to change — off a
public explorer that rate-limits and sees every address, onto their own indexer — and it
was the one they could only change with a shell and a restart. It now lives in
service_connections under 'esplora' and is edited at Wallet -> Settings -> Chain source,
probed against /blocks/tip/height before it is stored.
The URL joins the backend fingerprint, so re-pointing rebuilds every on-chain backend and
drops the gap-limit scan taken through the old endpoint. /_health probes what the wallets
actually use rather than the built-in default, and /_officer/config no longer reports a URL
it cannot know.
Also two receive-screen defects the Blockstream 429 exposed: a query error rendered as
"No address available", and the "new address" button called refetch() on the ?peek=true
query, so it re-fetched the same address instead of advancing the index.

the PATCH route already accepted a name; nothing in the UI ever sent one. adds an
inline editor on the settings header (pencil → input, enter saves, escape cancels)
and a rename mutation. renaming touches only the label, so it needs neither the
passphrase nor an unlocked wallet.
the route took the name unvalidated — it now trims and refuses a blank one, with a
64-char cap matched on create so a name you can create is one you can type back.

Opening a wallet meant waiting for a full gap-limit scan before any number appeared, and a
restart threw that work away. Worse, an unreachable Esplora rendered identically to an empty
wallet — as a zero balance — which is alarming for the one case where it is not true.
The backend now keeps a snapshot and serves it stale-while-revalidate: a snapshot inside the
TTL is served as-is, an older one is served immediately with a refresh started behind it, and
only a wallet that has genuinely never been read blocks on the network. wallet_chain_cache
holds one row per wallet so a refresh is a single atomic upsert.
The snapshot, not the endpoint, is the unit of caching. Balances, UTXOs and history were
three fetches over a shared scan, so the three queries a wallet screen fires on mount could
each observe a different moment; building them together costs the same requests and fixes
that incidentally.
Only the chain's own facts are stored. Addresses, scripts and pubkeys are re-derived from the
account xpub on load — cheaper than persisting them, and it means a restored snapshot cannot
disagree with the wallet's actual keys. Stored coordinates are validated rather than trusted,
and a snapshot at an unknown version is discarded, not migrated.
Two reads deliberately opt out. sendCoins takes a fresh snapshot because selecting coins from
a cached UTXO set builds a transaction spending outputs that may already be gone, and that
failure arrives as a broadcast rejection after signing. nextUnused does too, because handing
out an address whose stale record says "unused" is silent address reuse — a privacy leak the
owner cannot see or undo. Receive-address generation is therefore the one read that stops
working while the upstream is down, on purpose.
Failures are recorded alongside the last good snapshot rather than replacing it; wiping data
on failure would reproduce the exact bug this exists to fix. Every cache operation is
best-effort, so a database problem degrades to a slow load and can never fail a wallet
request. A sync block on balances, transactions and utxos carries the age to the UI, which
now distinguishes "empty" from "never read".
Verified against three live mainnet wallets: snapshots persisted and reloaded, and two
wallets kept their data and age through a real Esplora rate-limit failure while recording the
error separately.

A wallet whose Esplora endpoint was slow or down rendered as a wallet with no data at all,
rather than as an error. The cause was a timeout inversion: Bun.serve's default idleTimeout
is 10s, which is shorter than the Esplora client's own 20s per-request timeout. Bun killed
the response before the scan could either finish or report why it had not, so the failure
never reached the handler that would have surfaced it.
The ceiling has to sit above the whole gap-limit walk, not one request — a scan is many
sequential rounds of address queries. Raised to 255s, Bun's maximum, which is what every
other sidecar already uses.

An LND seed is not a BIP39 mnemonic. It shares the 24-word shape and the English wordlist,
which is exactly why it fails confusingly: the words validate as plausible input, the
checksum does not, and the user is told their own seed is invalid.
aezeed is a different construction — a 19-byte payload (version, birthday, 16-byte entropy)
sealed with AEZ under scrypt(passphrase, salt), with the salt carried in the mnemonic
itself. So it needs its own decipher, not a flag on the BIP39 path. The vendored aez/aezeed
implementation under sidecar/wallet/aezeed does that, and the recovered entropy becomes the
BIP32 root the same way BIP39 output does.
The seed envelope gains a kind ('bip39' | 'aezeed') so an unlock knows which derivation to
run rather than guessing from word count, which cannot distinguish them.
Also note the aezeed passphrase is not a BIP39 passphrase: it decrypts the seed rather than
salting the derivation, so a wrong one fails the checksum outright instead of silently
producing a different wallet. The UI can therefore tell the user they typed it wrong, which
is not possible for BIP39.

covers both encryption layers, what each one does and does not protect
against, the watch-only-while-locked property and the unlock session
rules. records the known limits: the heap cannot be reliably wiped, the
storage key is derived with a plain sha-256 rather than a kdf, and
rotating VAULT_STORE_KEY has no migration path.
also corrects the changePassphrase doc comment, which claimed rotation
never touches the dek. it mints a fresh salt, dek and ivs.

the owner's work, committed as one unit rather than split: the registration
files (App.tsx, Dock, AppRegistry, hono.ts, the schema and db barrels,
ecosystem.config.cjs) all reference modules under src/servers/{api,sidecar}/wallet
and src/workspaces/officerdev/src/apps/Wallet, so committing the shared plumbing
on its own would leave a commit that does not build.
officer-wallet is a new pm2 peer holding seed material sealed under an owner
passphrase on top of VAULT_STORE_KEY, with an unlock ttl after which the root key
is wiped from memory. five backends: on-chain via esplora, and lnd, clnrest,
lndhub and nwc for lightning. bolt11 encode/decode is implemented in-tree.
no secrets in the diff — the key-shaped literals under sidecar/wallet are the
bolt11 spec vectors and the bip39 "abandon … about" vector. .env.example gains
placeholders only. bun test src/servers/sidecar/wallet: 38 pass, 0 fail.
not reviewed line by line; assembled and verified to build, not audited.
