Bring-your-own, the open question the migration plan left. Point this
wallet at a phrase you already hold — Minibits, Nutstash, cdk-cli — and
its coins become restorable here, which is the other half of "these
words are portable".
Replacing an established phrase is the one genuinely lossy thing this
module can do, so it is treated that way. The coins already held stay
spendable: they are proofs, not derivations, and nothing here touches
`ecash.json`. But they were minted under the *old* phrase, so a restore
will no longer find them. Hence an explicit confirm, a prompt to reveal
and write down the current phrase first, and — most importantly — the
replaced phrase is archived beside the wallet, never overwritten. It may
be the last copy of the words a balance was minted under, and quietly
destroying that is precisely what this module exists to prevent.
Re-importing the phrase already in use is a no-op rather than a
replacement, so it archives nothing.
Counters are deliberately left alone. They are per-keyset and
seed-relative, so under a new seed they merely start high, which costs
nothing because a restore scans from zero regardless. Resetting them
would be the dangerous choice on the day someone imports the phrase they
were already using.
`imported` is its own provenance rather than reusing `independent`: both
mean the node's recovery phrase does not cover the wallet, but only one
of them means the operator already knows where else the words live.

Until now every Cashu proof this node held was backed by a secret drawn
from OsRng and written to exactly one file. Losing wallet/ecash.json
lost the coins outright — no phrase to write down, and nothing the mint
could do about it. Ecash is a bearer instrument, so "one file, no
backup" was the sharpest edge in the wallet.
NUT-13 derives each proof's secret and blinding factor from (seed,
keyset id, counter) instead. The wallet becomes a phrase, and the coins
can be re-derived and re-claimed — here or in any other NUT-13 wallet.
The phrase is its own 24 words, derived from the node master seed over a
fixed HKDF path. Both halves matter: it is still covered by the node's
recovery phrase, so there is nothing extra to write down; but it is
portable, so restoring ecash into Minibits or cdk-cli does not mean
handing over the key to the entire node.
It sits on disk unencrypted, deliberately. The master seed needs the
operator's password to open, which no background mint or swap can ask
for; and this file lives beside wallet/ecash.json, which already holds
spendable bearer secrets in plaintext. It regenerates exactly those
secrets, so it is the same sensitivity class as the file next to it.
0600, like identity/nostr_secret, which is derived and persisted the
same way.
Counters are reserved *before* the mint call and never rolled back. A
gap costs a restore scan a few extra probes; a reused counter costs a
coin, because two proofs with the same secret can only be spent once.
Restore is the half that cannot be done offline: a re-derived secret is
not money until the mint's signature over it exists. /v1/restore returns
those signatures; unblinding reconstitutes the proofs. It is additive
and idempotent — coins already held are skipped by secret, spent ones
are counted but not added — so it is safe to press on a working wallet,
which is when someone is most likely to reach for it.
Existing nodes activate on the first visit to Settings → Ecash backup
phrase: that password prompt is the only moment the master seed can
legitimately be opened. New nodes get it at onboarding. Until then the
behaviour is exactly as before — valid proofs, no backup — and the card
says so rather than implying a backup already exists.

Executes steps 1-3 of docs/cashu-cdk-migration-plan.md, plus the test-coin
switch needed to exercise these routes without spending real sats.
Protocol layer: depend on `cashu` 0.17.5 (MIT, the crate CDK is built on,
default-features off, `wallet` only). Keyset ids now go through upstream's
`Id::from_short_keyset_id` / `ShortKeysetId` instead of the prefix match
hand-rolled in 2277fc46 — same repair, but implemented by the reference
code that defines the rule, so the next spec turn is a version bump rather
than another incident. `MintClient` feeds it the mint's `/v1/keysets` in
upstream's own `KeySetInfo` shape, parsing entries individually so one
keyset in an unmodelled unit can't block resolving the id we need.
Adding the crate required relaxing `bip39 = "=2.1.0"` to `"2.1"` (resolves
2.2.2): the exact pin held `unicode-normalization` at 0.1.22 and no
resolution existed otherwise. The pin carried no recorded rationale; seed
tests cover the bump.
Network switch: `wallet.ecash-network` / `wallet.ecash-set-network`, with a
Test mode toggle in Wallet Settings → Cashu. Cashu has no testnet, so this
points the wallet at the public `testnut` mint — but crucially each network
gets its OWN wallet and accepted-mints file, because test and real proofs
in one purse would be spendable interchangeably and the balance would be a
lie. Mainnet keeps the original filenames, so existing funds files are
untouched and switching is reversible: tests assert a real balance survives
a round trip through test mode.
Headless coverage: scripts/test-ecash-routes.sh drives every ecash RPC over
the real HTTP path (network get/set, balance, history, mint quote + claim,
send, receive, double-redeem refusal, garbage input, melt quote), restores
the node's original network on exit, and exits non-zero with the failure
count.

Some apps carry a complete account system and are broken by an upstream
challenge: git clients speak basic-auth (not browser cookies), and a
BTCPay checkout link handed to a customer must open for that customer.
Both were behind the gate's login page — the "non-browser clients need an
access token" gap disclosed in five consecutive releases.
- New manifest port policy `auth: open`: the daemon still fronts the port
exactly like `gated` (loopback pin, external binds, frame-header fixes,
app-down retry page, Tor upstream) but serves it without the login
challenge. Requires auth_rationale, same burden of proof as `none`.
Gitea 3001 and BTCPay 23000 declare it.
- Runtime operator override per app (security.set-app-gate → app-configs/
<id>.json "gateEnabled"), surfaced as Settings → app → Access control.
Wins over the manifest in both directions and applies on the next
request — no restart, and it works today on catalog-covered apps whose
signed manifest still says `gated`.
- The gate resolves policy per-request from the live port map, so a
toggle takes effect without waiting for the 60s rebind sweep. "Off"
never releases the port: gated apps are loopback-pinned, so releasing
would strand them, not open them.
- security.app-gate-status now reports gate_enabled + any override.
- New guard test pins the `auth: open` set (both entries reviewed); the
`auth: none` count moves 25 → 26, absorbing pre-existing drift from the
phoenixd onboarding (loopback JSON API with its own generated password).
- Docs: the manifest spec's ports row documented only host/container/
protocol — bind, auth, auth_rationale and session_passthrough were
undocumented. Added a full "Ports & the app gate" section plus a
developer-guide entry telling app authors to enforce their own auth
regardless, since the operator can flip the gate either way.
Verified live on archi-dev-box from an external address: gated → 401 gate
page; override off → Gitea 200 own page, BTCPay 302 to its own login,
git-over-HTTP info/refs 200; override on → 401 again; clear → default.

- lnd.createinvoice now returns r_hash_hex; new lnd.invoicestatus RPC
looks the invoice up (SETTLED + amt_paid_sat). E2E-verified on this
box: real invoice minted, status polls settled:false until paid.
- Receive modal: Lightning polls settlement every 3s and flips to the
on-chain-style success view — straight to the green check + amount
(no broadcast step; settlement is final). Raw bolt11 text removed:
QR + CopyButton only. State fully reset per open/close.
- CopyButton is now the wallet's only copy affordance: the ark-address
and ecash-token holdouts swapped in, their ad-hoc handlers deleted.

WebUI RULE (operator, 2026-08-14): never point users at a terminal. The
certificate section told users to run setup-node-ca.sh by hand — it now
has a Generate button backed by system.node-ca.generate, which runs the
idempotent script server-side (live-tested: generated and /ca.crt serves).
Routstr budget panel moves directly under the Claude API key card.
