Keep generated setup handoffs on their original account - #3314
Sign-out and wipe wait for foreground setup before withdrawing the KeyPackage slot. Removal reuses its foreground fence for cleanup, blocking local preparation only after publication has finished.
The fence also waits for admitted interactive onboarding steps. Teardown rechecks the captured account label against its original public key.
Concurrent creates keep sharing the original account after another attempt completes setup. New creates skip signed-out and unlinked journals, leaving those accounts unchanged.
What the race tests observe
Tests retain captured identities across removal and competing completion, including fixtures with another unfinished account. The secret-store recorder detects identities that are created and immediately rolled back.
KeyPackage publication races check slot deletion, queued cleanup, and local preparation progress while removal waits.
Summary by CodeRabbit
Bug Fixes
Improved generated-account setup recovery when an account is signed out, unlinked, or removed, helping prevent stale setup from restoring it.
Improved handling of setup attempts that overlap with sign-out, account removal, or wipe.
Fresh account creation now remains distinct from resuming an existing setup, including when account sign-in status changes during setup.
Documentation
Updated the runtime overview with account setup, recovery, and teardown behavior.
The background retry fix in #3285 leaves startup and foreground handoffs
using general create-or-resume requests. A captured identity can disappear
before those handoffs run, allowing a different identity to be created.
Continue only the captured account and keep local preparation and
foreground completion ordered with removal. Reuse the existing generated
setup mode, publication fence and per-account onboarding transaction.
Record every secret write in controlled startup and foreground races,
including replacements that are immediately rolled back. Also verify that
removal waits for an admitted foreground publication and that a stale
handoff leaves another unfinished account untouched.
Fixes#3290
Wait for admitted foreground setup before withdrawing the KeyPackage
slot. Wipe passes its held fence into local removal instead of taking
the non-reentrant foreground transaction again.
Take local preparation admission only for local removal, after waiting
for foreground setup, so a held publication cannot stall all local setup.
Treat a removed or signed-out startup identity as a clean end rather than
reporting an account failure.
Cover withdrawal order, preparation progress during removal and quiet
startup with controlled races. Record the two-phase teardown lock order.
AccountHome resolves custom account records by their persisted label, not
by the public key alone. Pass the captured label into local removal while
continuing to fence setup by public key.
This preserves wipe and secret-cleanup behavior for labelled accounts.
A second create can capture a pending account and wait while another
attempt finishes it. Its cleared journal means completion, not deletion.
Read the actual completed account state instead of reporting it missing.
Capture effective context with the selected identity under preparation
admission. Once selected, continue that identity without another
create-or-resume lookup that could choose a replacement.
Revalidate captured public keys after teardown admission and before local
removal so a reused label cannot redirect the operation. Cover concurrent
creates, background completion and label replacement with real API calls.
Replace mutex-reference bookkeeping in the withdrawal race with competing
public removals that expose incorrect teardown ownership.
Skip signed-out and unlinked journals when selecting resumable setup.
Keep their accounts, journals and credentials intact while allowing
foreground and local-ready calls to create another identity.
Return setup futures directly to avoid redundant async layout layers
that exceeded the simulator compiler limit. Document that teardown
also waits for interactive onboarding transactions.
Capture and validate setup selection before async preparation.
Resolve absence to fresh creation, not another resumable-journal scan,
so concurrent sign-in cannot switch the identity or relay context.
Retain a real preparation future across the durable sign-in transition
and verify that the original pending KeyPackage and context stay intact.
Generated account setup now separates identity selection, local preparation, and foreground or background handoff. Sign-out, wipe, and removal coordinate with setup work and revalidate the expected account. New tests cover setup recovery, concurrent handoffs, and teardown ordering.

Setup distinguishes resumable, fresh, and account-specific continuation. It skips signed-out or unlinked records and prepares local account state and key-package data. Tests cover identity selection and signed-out or unlinked accounts.

Foreground and background setup use explicit handoff outcomes. Network-ready creation finishes pending work or returns completed results, and setup can recover completed results when setup state is absent. Tests cover coalesced creation and foreground/background handoffs.

Sign-out, wipe, and removal wait for setup work and re-resolve the expected account before proceeding. Tests cover removal, label reuse, and teardown during publication. The guidance and architecture document describe the coordination and lock order.

Startup recovery handles only one unfinished generated setup. If a user has two active unfinished setups, such as after signing a previously signed-out account back in, the second stays incomplete across restarts. Account removal also retains a narrow race with same-label account replacement. Resolve the startup recovery gap before merging, and consider the removal race.

Explanation
The changes address the coding requirements in [#3290]. Generated setup now selects and continues the captured account, while fresh creation remains explicit. Teardown fences background and foreground setup, waits for admitted work, and coordinates local removal. Startup, foreground, and retry-related paths are covered by the setup handoff changes. Tests cover removed-account recovery, secret writes including temporary replacement identities, teardown ordering, concurrent creates, signed-out or unlinked journals, and preservation of another account's setup.

Explanation
The changed runtime code, onboarding tests, and test fixtures directly support [#3290]. The AGENTS guidance and runtime architecture documentation describe the same account-bound setup, teardown, and removal rules. No unrelated implementation or documentation change is shown.

Resume every eligible generated setup at startup.
The new signed-out exclusion permits this sequence: retain unfinished setup A, sign out A, create unfinished setup B, then sign A back in while publication remains unavailable. Both accounts now have active generated journals. However, resumable_generated_account_setup returns only the first matching account, and start() calls this recovery method once. The other account receives no bootstrap continuation and retains its incomplete setup after restart. (raw.githubusercontent.com)
Enumerate eligible setup IDs and resume each through Continue. Keep the captured identity and context separate for each account. Add a restart regression that leaves two active journals and verifies that both reach NetworkReady.

Protect removal from same-key account replacement.
After this check, a failed external-signer login can roll back the original account while a concurrent import creates a local-signing account with the same label. Removal can then delete the imported account and its secret. Coordinate rollback and import with removal through its commit.

BUG FIX · ACCOUNT SETUP · FIXES #3290
A delayed setup handoff cannot create a replacement account after a wipe.
#3285 bound background retries, but startup and foreground handoffs still called create-or-resume without an account.
Completing the handoff
The foreground handoff in
onboarding/generated_setup.rsnames the original account:Sign-out and wipe wait for foreground setup before withdrawing the KeyPackage slot. Removal reuses its foreground fence for cleanup, blocking local preparation only after publication has finished.
The fence also waits for admitted interactive onboarding steps. Teardown rechecks the captured account label against its original public key.
Concurrent creates keep sharing the original account after another attempt completes setup. New creates skip signed-out and unlinked journals, leaving those accounts unchanged.
