**Category:** fix
**User Impact:** Users can navigate back while an identity key is being
created, while Next remains visible and unavailable until creation
finishes.
**Problem:** The key-creation hold hid both navigation actions, leaving
users without an escape route or a clear indication of what would happen
next. **Solution:** Keep the onboarding footer mounted throughout
creation, leave Back enabled, and gate Next on the completed identity
state.
<details>
<summary>File changes</summary>
**desktop/src/features/onboarding/ui/BackupStep.tsx**
Keeps the onboarding navigation footer visible during key creation, with
Back available and Next disabled until the identity is ready.
**desktop/tests/e2e/onboarding-backup.spec.ts**
Covers the loading and completed navigation states so the intended
behavior cannot quietly crawl back out of the pit.
</details>
## Reproduction steps
1. Start desktop onboarding and choose to create a new identity.
2. Submit the profile step and observe the key-creation screen.
3. Confirm Back is enabled while Next is visible but disabled.
4. Wait for key creation to finish and confirm Next becomes enabled.

## Summary
Adds a locally stored **NIP-49 encrypted key backup** (`ncryptsec`) to
the desktop app, per the plan reviewed in buzz-development (Rev 3,
approved 9/10 by Wren; implementation also reviewed and approved 9/10).
**Two-artifact design — canonical bytes originate entirely in Rust:**
- `create_ncryptsec_backup` runs under the `identity_mutation` lock:
encrypt → decrypt-verify against the live pubkey → atomic `0o600` write
to `{app_data_dir}/identity.ncryptsec` → reread/byte-compare → return
the exact persisted bytes. The frontend never re-derives or re-encrypts.
- `save_ncryptsec_copy` writes a portable copy via the save dialog
(parse-gated, secret-file semantics) and never mutates canonical state.
- `generate_backup_passphrase`: 6 words from the EFF short wordlist via
`OsRng` (custom passphrases min 12 chars).
- Import accepts `ncryptsec1` with optional password; the raw-`nsec`
path is untouched. Different-pubkey import and sign-out wipe the
app-managed backup (post-commit, best-effort — a failed import can never
destroy the still-live identity's backup; regression-tested).
**Never-relay guarantee (egress guard + tripwires):**
- `egress_guard.rs` fail-closed at all 8 `/events` submission boundaries
(relay submit funnel, 3× `relay.rs`, huddle STT, both engram submitters,
native WS choke point), rejecting `ncryptsec1`/`NCRYPTSEC1` in text and
binary frames. Scope is deliberately ncryptsec-only: pairing
intentionally carries raw nsec inside its encrypted session.
- Site-granular `/events` inventory tripwire: per-file (`/events` count,
guard-call count) pairs; unlisted files expect zero. Mutation-style
tests prove a ninth site in an existing file, a removed guard, and a new
unlisted file all fail the scan.
- ncryptsec source-allowlist scans in **both** trees (Rust + TS).
**Frontend:** onboarding `BackupStep` is encrypted-by-default — the
default path never invokes `get_nsec` (e2e asserts the command log).
Raw-nsec export stays behind an explicit click with prior semantics.
Shared `EncryptedBackupCreator` powers onboarding + a new settings row;
the import form auto-switches to encrypted mode on `ncryptsec1` paste
(case-insensitive HRP).
**Open product call for @tlongwell-block:** onboarding default is
*encrypted* in this PR; flipping to raw-default is a small change either
way (documented in the plan).
Review history: plan Rev 3 and the implementation were both iterated
with Wren to 9/10 (two blockers from round 1 — import ordering,
inventory granularity — plus an uppercase-bech32 hardening gap, all
fixed in `dde37183e`). Thread: buzz-development.
### Related issue
Follow-up to the direction explored in #385 (NIP-PB, closed) — this
ships local NIP-49 (the standard) instead of a new NIP. No open
duplicate found.
### Testing
All at exactly `dde37183e` (same shell, HEAD verified):
- `cargo test` — 1680 passed / 0 failed / 14 ignored (includes a
deliberate ~70s log_n-18 NIP-49 round trip, spec vector, wrong-password,
NFKC, uppercase-vector decrypt, injection test per egress boundary,
inventory mutation tests, import-ordering regression tests)
- `cargo clippy --all-targets -- -D warnings` — clean; `cargo fmt
--check` — clean
- `pnpm typecheck` — clean; JS unit suite 3529/3529; biome (repo-pinned
2.4.16) clean
- Playwright `onboarding-backup` / `onboarding` /
`onboarding-agent-defaults` / `profile-nsec-reveal` — 86 passed, 1 known
avatar-reservation flake (passed on rerun; untouched by this diff).
`passThroughBackupStep` now exercises the encrypted default, so every
downstream onboarding spec covers the new path.
- Note: browser e2e fakes the crypto via the mock bridge (fixed
spec-vector blob); decryption correctness is proven in the Rust tests.
## Latest onboarding integration
The current head adds an additive `IdentityInfo.storage` field
(`ephemeral`, `system-keyring`, `local-file`, or `environment`) so
onboarding can accurately explain where the active identity is
protected. It surfaces storage metadata only—never key material—and
leaves the existing lost/keyring-locked recovery behavior intact.

## Summary
- backing out of the backup step and clicking the CTA again reuses the
existing key
- the button still said "Create a new identity key", which is misleading
for a security-sensitive action
- when a key is already loaded, label it "Continue with existing
identity key"
Closes#2318
## Test plan
- [ ] first-run: button still says "Create a new identity key"
- [ ] create key → backup → back: button says "Continue with existing
identity key" and shows the same key
