fix(identity): wire the Identity Hub unload button and stop zombie removals

[Claudius-Maginificent]

TL;DR: The "Unload this identity from this device" button in the Identity Hub's Settings tab now actually works. Two latent data-loss bugs in the removal path it uses get fixed along the way — including one that could bring a removed identity back onto every screen after its private keys had already been destroyed.

User story

As an everyday user, I want to remove an identity from Dash Evo Tool on this device without losing its private keys if something goes wrong mid-removal, to achieve a clean local-only removal that I can safely retry.

Scenario

Base flow

A user opens Identity Hub → Settings for an identity they no longer want tracked on this device and clicks "Unload this identity from this device."

Actual behavior

The button has always been disabled, with a "coming soon" tooltip. The confirmation dialog behind it exists but is unreachable. There is no way to remove an identity from the current UI — the only working "Remove" control lives on a legacy screen that was intentionally hidden from the nav sidebar when the Identity Hub replaced it.

Separately, the shared removal path this button will use (delete_local_qualified_identity) clears the identity's vault keys (irreversible) before removing it from the local index. If either of the following steps fails, the identity is left as a "zombie": still listed and loadable in the UI, but its private keys are already permanently gone from the vault.

Expected behavior

Clicking "Unload this identity from this device" opens a confirmation dialog that states plainly that this permanently deletes the identity's private keys stored on this device, and that using it here again needs the user's own backup — the identity record itself stays on Dash Platform, but its local keys do not. Confirming removes the identity from this device. The removal path is reordered so a failure at any step leaves the identity either fully intact or fully gone — never listed without its keys — and a retry after any failure, or the app's own background cleanup, recovers cleanly.

Detailed discussion

What was done

• Enabled the button; the confirmation dialog's target identity is now captured into a PendingIdentityUnload { dialog, target } wrapper at click time, so the confirm action can never act on a different, later-selected identity (a TOCTOU bug previously found and fixed in a since-closed attempt at this feature, PR fix: masternode/evonode identity load deadlock + identity unload capability (#889) #925, before that fix was dropped along with the whole capability).
• Confirming dispatches the existing IdentityTask::RemoveIdentity task — no new backend task variant.
• Fixed the vault-key-clear-before-index-removal ordering bug in delete_local_qualified_identity (src/context/identity_db.rs): vault key placements are now read up front (while the record still exists), the identity is removed from the index and its blob purged, and the irreversible vault-key delete happens last. Two regression tests cover both failure directions (keys must survive a failed delete; a successful delete must not orphan vault entries).
• Follow-up (review feedback): purge_identity_scope is itself not atomic — it can fail on its own last write (pruning the scheduled-vote voter index) after its first write has already deleted the identity blob that the vault-key delete set is derived from. Added a durable, Global-scoped vault-cleanup manifest persisted before any mutation runs, retained across every error, and cleared only once every listed key is confirmed deleted — a retry now recovers the full set regardless of which step failed.
• Follow-up (review feedback): the Identity Hub's RemovedIdentities handler cleared the app-wide selection when it named the removed identity, but left ContactsState, pending contact confirmations, and the profile cache still bound to it — unlike every other identity-switch path in the same file. Now resets all three together, matching existing precedent.
• Follow-up (review feedback): added a boot-time sweep, AppContext::resume_pending_vault_cleanups, that resumes any vault-cleanup manifest left behind by a removal that failed after the identity was already delisted — the only reachable path back to those keys, since nothing in the UI can retry a removal for an identity that no screen lists anymore. Hardened over two more review passes: it re-runs the idempotent purge_identity_scope before deleting vault keys (in case a crash interrupted the removal before that step even started), takes the same per-identity record lock as insert_local_qualified_identity before re-checking roster membership (closing a race with a concurrent re-import of the same identity), and takes the same migration_run guard as delete_local_qualified_identity (a storage migration can be mid-rewrite of the same data around the same boot window).
• Follow-up (grumpy-review, blocking): the unload confirmation dialog and tooltip claimed the identity "can be loaded again later" while confirming permanently destroys its only on-device private keys for imported/vault-only identities. Reworded to state plainly that the keys are deleted and a backup is required to use the identity here again.
• Follow-up (grumpy-review, blocking): the new cleanup-pending success banner (shown when the vault-key delete itself fails after the identity is already delisted) described the leftover private key material as harmless "background files" in an auto-dismissing Success banner. Reworded to name the private keys explicitly and changed to a non-auto-dismissing Warning, matching the sibling associated-voter-identity outcome's treatment.
• Follow-up (grumpy-review, non-blocking): the associated-voter-identity delete inside remove_identity had not been given the same "is this identity already delisted?" check just added to the primary identity's delete — independently found by three reviewers. A voter identity removed but stuck mid-cleanup is now correctly reported as a completed removal with cleanup pending, not an unretryable failure.
• Follow-up (external review, blocking): the Global identity roster (det:identity_index:v1) is a single blob rewritten wholesale, and adding or removing an entry was an unguarded read-modify-write. The per-identity record lock does not close that window — it serializes writers of the same identity, while this race is between writers of different ones. Because the boot sweep now treats absence from that roster as proof an identity was removed, a clobbered import would hand a live identity's private keys to the next boot's deletion pass. Every mutation of that key (add, remove, and the devnet wholesale wipe) is now serialized by one process-wide lock. Two regression tests against a store that stalls between read and write cover both directions: a lost listing, and a delisted identity resurrected.
• Follow-up (external review, blocking): the unload confirmation prompt did not name the identity it was about to unload and did not block input, leaving the identity switcher clickable behind it — a user could open the prompt for one identity, switch the visible page to another, and confirm an unnamed prompt that still deleted the first one's keys. (The confirm action itself already acted on the identity snapshotted at click time; the gap was that the user had no way to see which one that was.) The prompt now names the identity by its Base58 ID and holds the screen behind it.
• Follow-up (external review): a removal whose vault keys were all deleted successfully, but whose bookkeeping manifest then failed to clear, was reported as "private keys are still stored on this device" — the exact opposite of what happened. The irreversible tail of a removal is now one shared function that returns an error only while key material may still exist; stale bookkeeping is logged and the removal counts as complete. The boot sweep, which had hand-rolled the same semantics separately, now shares that function so the two paths cannot drift.
• Follow-up (external review): the removal-outcome classifier in remove_identity now has direct tests (see the closed gap below).
• Follow-up (external review, blocking): the Identity Hub reset its identity-scoped caches only when the explicitly persisted selection named a removed identity, but the Hub can operate on a fallback identity when that pointer is absent or stale — and for a single-identity account the explicit pointer is never set at all, so the ordinary case reset nothing. If the fallback moved before the removal result arrived, ContactsState, pending contact operations and confirmations, and the profile cache stayed bound to a deleted identity, and the next render reused stale rows and its one-shot load guard while actions resolved under a different identity. The caches now reset when either pointer names a removed id. Dropping the app-wide selection deliberately stays on the narrower explicit-pointer condition — clearing a selection that still names a live identity would be a new bug.
• Follow-up (external review, blocking): the cleanup-pending warnings asserted more than the flag behind them can prove. cleanup_deferred shows only that a step failed after the identity left the roster: it does not establish that private keys remain (the failing step can be a purge for a keyless identity whose manifest holds no placements), and it cannot promise the keys will be cleared on the next launch (the boot sweep can be skipped during a storage migration, or retain the manifest after a further failure). Both messages now hedge presence, promise another automatic attempt rather than completion, and keep the one precaution the user can act on immediately. The cleanup_deferred doc comment and IDN-021's acceptance text were corrected in the same change, since all four stated the same absolutes.
• Follow-up (external review): the fixture behind the roster-race regression tests proved less than was claimed for it. It sleeps after taking its snapshot, and elapsed time creates no happens-before between the threads, so on a delayed runner both tests could pass with the roster lock removed. Replaced with a rendezvous fixture that releases reads only once every armed reader holds the pre-mutation snapshot, making the interleaving certain rather than likely. Verified by deleting the lock with the rendezvous in place: both tests fail every run, and pass once it is restored.
• Follow-up (external review, blocking) — a removed identity could come back. Removing an identity deleted its record and its keys but recorded nothing saying the user had deliberately unloaded it, and several paths re-create an identity record whenever one is found to be absent. Automatic discovery (which runs when Platform becomes ready, after reconnects, and on wallet unlock) would simply re-add it. Worse, and live on the paths users touch most: every fund-moving task — transfer, withdraw, top-up, add-key, register-DPNS-name — reads the identity, performs a network round-trip, then writes the modified copy back. An unload confirmed during that round-trip lands in the window, and the write re-creates the record and re-lists it. transfer writes back both sides, so this happened whether the user was sending from the identity or to it. The result in every case was a zombie: an identity visible on every screen whose private keys the removal had already destroyed. Fixed with a durable per-network unload marker, written before the identity is delisted and cleared only by a deliberate user load. It is consulted in the same lock-protected critical section as the write it guards, at the shared chokepoint every one of these paths passes through, so a path added later is covered by construction. The boot migration's identity import and the devnet wipe are covered too.
• Follow-up (external review, blocking): the Identity Hub tracked only the most recent in-flight unload, and consumed that record on any removal result rather than the matching one. Two overlapping unloads therefore lost the first one's identity, and a failure for one could discard another's record — leaving identity-scoped caches bound to an identity that no longer exists. Every in-flight unload is now tracked and consumed only by its own result, including on the error path.
• Follow-up (external review): the concurrency regression tests were relying on process-global counters as their readiness signal. Because the test binary runs tests in parallel, unrelated lock traffic could satisfy those conditions and release a test's synchronisation early — measured at three passing runs in four against deliberately unserialized code. The instrumentation is now scoped to the individual test that installs it, and the roster tests run an explicit noisy-neighbour thread so that independence is a condition of the test rather than an assumption about scheduling. The same tests fail four times in four against the same unserialized code.
• Follow-up (external review, blocking): the guard above decided whether an identity was gone by checking whether its stored record was present, which is not the authoritative answer. A removal delists the identity before purging it, and the purge's first step deletes that record — so if the purge failed partway, the identity was already off the roster while its record survived. A stale write then saw the record, bypassed the guard, and put the identity back on the roster, undoing an unload already reported as complete (after which the cleanup sweep would see it listed and deliberately spare its keys). The guard now asks roster membership, the same authority the boot sweep uses, so there is one answer to that question rather than two.
• Follow-up (external review, blocking): adding a key to a password-protected identity wrote the new key into the vault before the record update. If the identity was unloaded during the network broadcast, the removal deleted only the key placements the stored record knew about, and the new key was then written afterwards — leaving a private key on the device that nothing references and nothing can enumerate, immediately after telling the user that identity's keys had been deleted. The task also reported success. The key is now refused before anything is written, under a single hold of the identity's record guard, with a dedicated error explaining what happened.
• Follow-up (external review, blocking): the cleanup-pending warnings promised the app would try again "the next time you open it", but the boot sweep returns without attempting anything if a storage update is running or its records cannot be read — and the warning does not survive a restart, so reopening at the wrong moment could remove the only warning without ever making the attempt. Both messages now describe a continuing automatic effort without tying it to a particular launch, and keep the precaution to treat the device as still holding the keys until then.
• Verified the previously-flagged lock-ordering concern between unload/load paths (PR fix: masternode/evonode identity load deadlock + identity unload capability (#889) #925 SEC-001) is already sound in the current code (migration_run + per-identity record lock) — no change needed there.
• Added a RemovedIdentities result arm to the Identity Hub screen (success/partial-failure/cleanup-pending banner, clears a stale selection pointing at a removed identity) — previously this result type had no UI feedback at all when triggered from this entry point.
• Deduplicated the removal-outcome copy between the legacy screen and the hub instead of adding a second copy of the same strings.
• Added docs/user-stories.md story IDN-021, marked [Implemented], kept current across every follow-up above.
• Documented the new det:vault_cleanup_pending:v1:<id> k/v key in docs/kv-keys.md and corrected its summary counts table.

Previously-recorded gap, now closed

remove_identity (src/backend_task/identity/remove_identity.rs) — the function orchestrating both identity deletes and the cleanup-pending/associated-voter-failure classification — had no dedicated unit test of its own, and the primary and voter branches had already drifted apart once during this PR. It now has four, each with a deterministic failure injection covering the distinction that matters: a failure before the identity is delisted must propagate as an error (the identity is provably still listed), while a failure after must report the removal as complete with cleanup pending. The shared staging fixtures moved out of identity_db.rs's private test module into the repo's existing test-support module, plus a new fixture for an identity with an associated voter identity — nothing in the tree built one before, so those branches had never had a fixture at all.

Out of scope for this PR (tracked separately)

• DashPay/DPNS-specific cleanup on removal (PR2, stacked on this branch).
• A devnet-only wholesale-wipe path with the identical vault-key-before-index ordering bug.
• src/ui/masternodes/detail_screen.rs's remove_node has the same post-delisting message-accuracy gap this PR just fixed on the identity removal path (three reviewers independently found this via a call-tree walk on delete_local_qualified_identity, which this PR's own reordering changed for every caller): a delete failure that lands after the masternode is already off the roster is still reported as "couldn't be removed, try again," with the detail view left open on an already-gone node. Fixing it means applying the same is_identity_listed pattern to a screen this PR doesn't otherwise touch — recommend a small, fast follow-up PR.
• register_test_wallet's upstream registration has a fixed ~1s budget (50 retries × 20ms) and fails with WalletNotFound when it expires, which makes every test using it timing-sensitive on a loaded CI runner. One such test failed on an intermediate commit of this branch with exactly that payload and passes locally, in isolation and in the full suite. Not caused by this PR — the failing call is on the wallet-registration path, which never reaches the identity roster or its new lock — but the fixed retry count should become a real deadline. Recommend a separate issue.
• src/ui/identities/identities_screen.rs's own, older removal confirmation has the same non-blocking-modal shape this PR just fixed on the Identity Hub's prompt. Untouched here — it belongs to a legacy screen this PR does not otherwise modify — but worth a look if that screen is still reachable.
• Defensive hardening idea: have the vault-cleanup sweep enumerate the vault's own scope rather than relying only on the blob/manifest-recorded placements. Not a live bug under the current sequencing (the manifest already captures the complete delete set before any mutation runs) — recorded for future-proofing if that sequencing ever changes.
• A minor availability nit: the new boot sweep's migration_run guard can occasionally make a genuinely-unrelated mid-session removal attempt see "storage update is still running" if the sweep is running concurrently. Confusing but harmless (retry works); a clean fix needs broader error-messaging rework shared with the primary guard's error path.
• DRY cleanup: the three-way removal-outcome banner logic is currently copy-pasted between the Identity Hub and the legacy identities screen rather than shared.
• Maintainability: resume_pending_vault_cleanups has grown into a ~150-line function doing several jobs; a structural refactor is reasonable but deliberately not done in the same PR that just hardened its correctness twice.
• load_identity has a pre-existing key-orphan window: it seals key material into the vault before inserting the identity record, so any error between those two steps can leave a private key on the device that nothing references. Not introduced by this PR and not on the unload path — the same remedy applied to add-key above would close it. Recorded for a follow-up.
• Missing kittest UI-integration coverage for the actual click → confirm → dispatch flow and the 3-way removal-outcome banner (only the pure decision function is unit-tested today).

📝 Walkthrough

Walkthrough

The PR enables identity unloading from Settings. It adds target-specific confirmation, migration checks, durable vault-cleanup recovery, serialized identity-index updates, cache invalidation, and qualified removal outcome reporting.

Changes

Identity unloading

Layer / File(s)	Summary
Unload confirmation and dispatch src/ui/identity/settings.rs, src/ui/components/confirmation_dialog.rs, docs/user-stories.md	Settings snapshots the target identity, names it in the confirmation, blocks input behind the modal, checks migration state, and dispatches IdentityTask::RemoveIdentity.
Recoverable identity cleanup src/context/identity_db.rs, src/context/wallet_lifecycle/bootstrap.rs, src/wallet_backend/kv_test_support.rs, src/context/contract_token_db.rs, src/context/mod.rs, docs/kv-keys.md	The database persists vault-key placements before mutation, serializes identity-index updates, deletes vault keys last, and resumes incomplete cleanup during wallet bootstrap. Tests cover partial purge recovery, concurrent re-imports, manifest encoding, and index races.
Removal result reporting src/backend_task/identity/remove_identity.rs, src/backend_task/mod.rs, src/ui/identities/mod.rs, src/ui/identities/identities_screen.rs	The backend distinguishes failures before and after delisting. Shared banner selection reports deferred cleanup and associated voter cleanup outcomes without asserting key presence or guaranteed next-launch cleanup.
Removal-driven cache invalidation src/ui/identity/hub_screen.rs	The identity hub tracks dispatched unload targets and resets identity-scoped caches when a removal result affects explicit, retained, fallback-selected, or previously dispatched identities.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟡 Moderate · up to 64393

The PR makes local identity unloading reachable and adds durable cleanup and recovery, but the current head still allows a concurrent whole-device devnet wipe and re-import to delete newly written private keys or leave local identity state inconsistent. Merge should wait for that synchronization gap to be fixed or explicitly accepted by the owner.

Preliminary review — Codex only

The confirmation target snapshot and typed task dispatch are sound, but the deletion sequence still loses its only vault-cleanup manifest across several partial-failure boundaries, defeating the PR's safe-retry guarantee. The new result handler also needs to reset identity-scoped UI state when the removed identity was selected.

In `src/context/identity_db.rs`:
- [BLOCKING] src/context/identity_db.rs:1414-1421: Persist the key deletion set across partial removal failures
  `vault_keys` exists only on the stack, but the method performs several independent persistent mutations after reading it. Once `index_remove_identity` succeeds, `purge_identity_scope` deletes `IDENTITY_KEY` before its fallible top-up and scheduled-vote cleanup; an error after that first delete leaves the identity unlisted and destroys the only durable record of its vault placements. `IdentityKeyView::delete_all` creates another failure window because it deletes labels independently, continues after an error, and returns the first error at the end. Retrying either case reads no identity blob, obtains an empty placement set, and can return success while vault entries remain orphaned and unreachable through the application. Persist a deletion manifest outside the identity scope before the first mutation, retain it across every error, and clear it only after every vault label is confirmed absent. Add fault-injection tests for a failure after the blob deletion and for a partial multi-key vault deletion followed by a successful retry; the current failure test corrupts the index and therefore stops before any persistent mutation.

In `src/ui/identity/hub_screen.rs`:
- [SUGGESTION] src/ui/identity/hub_screen.rs:590-596: Reset identity-scoped state after unloading the selected identity
  Clearing the app-wide selection does not clear `ContactsState`, pending contact confirmations/tasks, or the profile cache. If the asynchronous unload completes after the user switches to Contacts and exactly one other identity remains, the next frame automatically resolves that remaining identity as Home while `load_requested` and the displayed contact rows can still belong to the removed identity. Pending confirmations can likewise retain tasks for the removed identity. Reset these fields here just as the existing wallet and identity switch paths do.

[thepastaclaw]

Preliminary review — Codex only

The durable cleanup manifest and Identity Hub cache reset resolve both prior findings. One blocking gap remains: once a late cleanup step fails, the identity disappears from the roster and the application provides no path that resumes its pending manifest, so the advertised user-retry flow cannot complete.

In `src/context/identity_db.rs`:
- [BLOCKING] src/context/identity_db.rs:1471-1478: Resume pending cleanup after the identity leaves the roster
  `index_remove_identity` makes the identity disappear from every roster-backed UI before `purge_identity_scope`, `IdentityKeyView::delete_all`, and manifest clearing have succeeded. If one of those later operations fails, the backend returns an error rather than `RemovedIdentities`; on the next frame the Hub loads `IDENTITY_INDEX_KEY`, no longer renders the identity, and has no target with which to dispatch `RemoveIdentity` again. The manifest is durable, but its only reader is `pending_vault_key_placements`, which runs only when `delete_local_qualified_identity` is called with an already-known ID. No startup or background path enumerates `VAULT_CLEANUP_PENDING_PREFIX`, even though `DetKv::list` supports doing so. A partial vault deletion can therefore leave keys and the manifest indefinitely, and the test's direct second call using `staged.id` does not represent a reachable application flow. Add an automatic recovery driver for pending manifests, or preserve the failed removal target in typed application state and expose a real retry action until cleanup succeeds.

Preliminary review — Codex only

The new bootstrap enumeration fixes the prior unreachable-retry defect, but the recovery sweep can still discard its manifest before the complete identity scope is purged and can race with a concurrent re-import, causing residual state or deletion of newly imported keys. Both defects violate this PR's safe-retry and no-zombie guarantees and must be fixed before merge.

Still open at 4821e0a — and independently corroborated by all three reviewers in this pass, so I am recording the extra evidence here rather than opening a duplicate thread.

The sweep's own code path confirms it: resume_pending_vault_cleanups goes manifest read → delete_all (identity_db.rs:1589-1591) → kv.delete(DetScope::Global, &key) (:1592). No purge_identity_scope anywhere in between.

Two additions to what you already wrote:

• The residue is not inert. get_scheduled_votes() (identity_db.rs:1882-1890) enumerates from the Global voter index, feeding both the DPNS contested-names screen (ui/dpns/dpns_contested_names_screen.rs:165) and the scheduled-vote executor (backend_task/contested_names/mod.rs:197). A stale voter-index entry keeps resolving a voter whose blob and keys are both gone. And since Platform identity ids are permanent, a later re-import of the same id silently inherits top-up history from a deletion the user was told had completed.
• Worst sub-case is worse than "leftovers". If kv.delete(scope, IDENTITY_KEY) is itself the failing write, purge_identity_scope returns immediately, the blob survives with its InVault placeholders, and the sweep then deletes the backing secrets — reconstituting exactly the zombie identity this PR exists to abolish, one boot later.

resume_pending_vault_cleanups_recovers_a_manifest_no_ui_can_reach (identity_db.rs:3316-3355) stages precisely this failure and then asserts only that the vault keys are gone and the manifest cleared — it never checks the Identity scope, which is why the gap ships under green tests.

Remedy is unchanged from your comment: call the idempotent purge_identity_scope(&kv, &id) before delete_all, clear the manifest only when both succeed, and extend that test to assert an empty Identity scope (no blob, no TOP_UPS_KEY, no scheduled-vote entries, voter index pruned).

Fixed in daf7c905, and fixed properly rather than decoratively. Verified at 2086609:

• resume_pending_vault_cleanups now calls purge_identity_scope(&kv, &id) at identity_db.rs:1607 — before delete_all (:1618) and before the manifest clear (:1621). A purge failure hits continue, so the manifest survives for the next sweep instead of being retired over a half-purged scope.
• The worst sub-case we worried about — kv.delete(scope, IDENTITY_KEY) itself failing, leaving a blob full of InVault placeholders while the backing secrets get deleted anyway — is now unreachable in that order.
• resume_pending_vault_cleanups_recovers_a_manifest_no_ui_can_reach (:3345) was extended to stage a pre-purge crash and then assert all four: blob gone, TOP_UPS_KEY drained, scheduled votes empty, voter index pruned. The test comment even explains why the manifest is staged directly rather than through a failing delete_local_qualified_identity — because the real call would always leave the blob already gone and prove nothing. That is the right instinct.

🔴 Blocking: Serialize cleanup recovery with same-identity writers

The sweep determines roster membership from one snapshot and later deletes the manifest's vault labels without taking identity_record_lock.

Still open at 4821e0a, independently corroborated by all three reviewers this pass. Adding evidence here rather than opening a duplicate thread — and the window is wider than the comment states.

It breaks a written invariant, not just an ordering hunch. docs/ai-design/2026-07-28-legacy-identity-recovery/design.md:776-789 records as shipped that AppContext::identity_record_lock(identity_id) is taken inside insert_local_qualified_identity, update_local_qualified_identity, set_identity_alias, delete_local_qualified_identity and both tier migrations, "so coverage does not depend on remembering it at each of ~20 call sites", with lock order migration_run → record guard. That same section names the exact hazard it was built for: a concurrent writer "erases the restored keys with no error anywhere". resume_pending_vault_cleanups is a new writer of precisely that state and takes neither guard.

A fresher snapshot would not close it. insert_local_qualified_identity calls encode_identity_blob_vault_first (identity_db.rs:784-785, which invokes IdentityKeyView::store_all) and only then index_add_identity (:797). So every re-import has an intrinsic window in which fresh secrets are already in the vault while the identity is legitimately absent from the index. A sweep sampling the roster inside that window sees "not listed" and deletes the just-written secrets — with a perfectly current snapshot.

And the concurrency is structural, not incidental. ensure_wallet_backend stores the backend and drops _build_guard at context/mod.rs:1151-1152 before awaiting bootstrap_loaded_wallets() at :1174. Any wallet-touching task reaching ensure_wallet_backend in that interval takes the fast path (mod.rs:1131) and proceeds while the sweep is still running. It is also driven per-network, so a mid-session network switch reopens the window — this is not confined to first launch.

Outcome of a hit: a listed identity with a live blob full of InVault placeholders and no backing secrets. IdentityKeyView::delete (wallet_backend/identity_key_store.rs:201-207) removes Tier-2 password-protected envelopes with no password and no prompt, so protection does not save the user. No test covers the interleaving — both sweep tests run single-threaded against a pre-corrupted static store.

Your proposed remedy holds: take identity_record_lock(Identifier::from(id)) per manifest, re-read index membership inside it, and hold it through purge, vault delete and manifest clear. Worth extending the design doc's writer list with the sweep so the invariant stays auditable.

Fixed in daf7c905. Verified at 2086609:

• resume_pending_vault_cleanups now takes self.identity_record_lock(Identifier::from(id)) per manifest (identity_db.rs:1566) and holds it through the roster re-check, the purge, the vault delete, and the manifest clear — the same guard insert_local_qualified_identity takes at :681, so the re-import interleaving is genuinely serialized rather than merely narrowed.
• The roster read moved inside the loop and inside the lock (:1576), with a comment explicitly forbidding hoisting it. That closes the variant I raised where a perfectly fresh snapshot still loses, because insert_local_qualified_identity writes secrets via encode_identity_blob_vault_first before index_add_identity.
• resume_pending_vault_cleanups_is_serialized_against_a_concurrent_reimport (:3525) covers the interleaving deterministically by holding the record lock while the sweep runs.

One residual worth a line of ink, not a blocked merge: the design doc at docs/ai-design/2026-07-28-legacy-identity-recovery/design.md:776-789 still enumerates the writers that take identity_record_lock and the sweep is not among them. Adding it keeps the invariant auditable for whoever inherits this.

Code fix re-verified at ec23526c and it holds: the record lock is taken per manifest at identity_db.rs:1599-1602, the roster re-read sits inside it at :1609 (not hoisted), and the guard spans purge, vault delete and manifest clear. resume_pending_vault_cleanups_is_serialized_against_a_concurrent_reimport (:3599-3677) proves the sweep blocks on a held record lock.

Leaving the thread open for the one residual I flagged earlier, which is still outstanding: docs/ai-design/2026-07-28-legacy-identity-recovery/design.md:776-779 still enumerates only insert_local_qualified_identity, update_local_qualified_identity, set_identity_alias, delete_local_qualified_identity and the two tier migrations as identity_record_lock takers. The sweep now takes the same lock and is not on that list. 4821e0af touched only a comment in wallet_lifecycle/bootstrap.rs, not this doc.

One line in that enumeration keeps the invariant auditable for whoever inherits it — which is the entire reason the list exists. _{🤖 Claudius the Magnificent}

Claudius the Magnificent — review of PR #962

Three specialist reviewers (security, project/structure, adversarial QA) went over this independently. 16 findings: 7 MEDIUM, 9 LOW. Five MEDIUM findings are attached inline; two more are already live in open threads and are covered below rather than duplicated.

The good news first, because it is genuinely good

The thing this PR set out to fix is fixed, properly. Reordering delete_local_qualified_identity — capture the vault-key placement set before the blob that records it is dropped, unlist, purge, and only then perform the irreversible vault delete — is correct, and a_failed_identity_delete_never_destroys_the_vault_keys is a real RED-before-GREEN regression test, verified against the pre-change ordering. The PendingIdentityUnload confirm-time snapshot is the right defence against the breadcrumb-switcher TOCTOU, and it is tested rather than asserted. The manifest carries no secret bytes, respects the secret_seam chokepoint, follows the det:<domain>:v1 naming convention, and fails closed on malformed keys. StoredPrivateKeyTarget mirrors PrivateKeyTarget exhaustively, so an upstream variant addition breaks the build instead of silently dropping placements. No new unwrap, no dependency churn.

The less good news

All the risk has migrated into resume_pending_vault_cleanups, added in the last two commits. All three reviewers converged on the same two defects — which happen to be the two threads still open on this PR, now with independent corroboration:

• r3872064655 (no purge_identity_scope in the sweep) — confirmed. The sweep resumes only the last step of a removal, then discards the manifest. A removal that died inside the non-atomic purge_identity_scope permanently strands the blob, top-up history, scheduled votes and a Global voter-index entry — and that voter index is live: get_scheduled_votes() feeds both the DPNS contested-names screen and the scheduled-vote executor. Worst sub-case: if kv.delete(scope, IDENTITY_KEY) is the failing write, the blob survives with its InVault placeholders and the sweep then deletes the backing secrets — reconstituting exactly the zombie this PR abolishes, one boot later. Your own sweep test asserts key deletion and manifest clearing, never residue.
• r3872064666 (no identity_record_lock) — confirmed, and wider than stated. The sweep is the only writer of identity key material that skips the record lock, breaking an invariant docs/ai-design/2026-07-28-legacy-identity-recovery/design.md:776-789 records as shipped specifically so coverage does not depend on remembering it at ~20 call sites. The roster snapshot cannot rescue it: insert_local_qualified_identity writes vault secrets at identity_db.rs:784-785 and only indexes at :797, so a re-import has an intrinsic unlisted-with-live-secrets window — a sweep sampling inside it deletes freshly imported keys even with a perfectly fresh snapshot. And ensure_wallet_backend drops _build_guard at context/mod.rs:1151-1152 before awaiting bootstrap_loaded_wallets() at :1174, so the concurrency is structural, not theoretical.

Inline above, additionally: the sweep bypasses the migration guard and is invoked from inside the migration before the identity import repopulates the roster it trusts (SEC-002); the Err contract inverted while three callers still tell users to retry or restart — restarting being precisely what runs the sweep (CALL-001); the "boot-time" framing is wrong in three ways (PROJ-002); the new durable key family is missing from the exhaustive docs/kv-keys.md catalog (PROJ-001); and IDN-021 is tagged [Implemented] while advertising a retry the design deliberately does not provide (DOC-001).

Deferral candidates (reported, not filed anywhere — your call)

• Recovery-aware unload copy. Flagged again by the security reviewer because this PR is what makes the button reachable for the first time. Your scope ruling in r3870649171 stands and I have not re-litigated it inline — noting it only so the deferral stays visible.
• Devnet wholesale wipe (delete_all_local_qualified_identities_in_devnet) still carries the pre-fix ordering and writes no manifest, so the new sweep cannot recover it either. Devnet-gated, PR-declared out of scope, but it should not sit indefinitely.

Verdict

Requesting changes. Every blocking item is in this PR's own follow-up code, not pre-existing behaviour, and each has a small remedy: call the idempotent purge_identity_scope before the vault delete, hold identity_record_lock across the roster re-check and the delete, and honour the migration guard. The underlying reorder needs no rework whatsoever — it is the best part of this changeset.

🟠 MEDIUM — the sweep bypasses the migration guard, and is invoked from inside the migration

delete_local_qualified_identity refuses to run during the storage migration, twice over (identity_db.rs:1449-1455): migration_run.try_lock() fails because finish_unwire::run holds that mutex for the whole migration (finish_unwire.rs:601-618), and migration_status().state().is_in_progress() is checked separately. run_backend_task_inner refuses every wallet-touching task in the same window (backend_task/mod.rs:1087). The stated reason is that sidecar state is only partially mirrored while the migration runs.

resume_pending_vault_cleanups performs the same irreversible delete_all and honours neither guard. That alone would be untidy. What makes it sharp is that it is reachable from inside the guarded region:

• new call site is bootstrap_loaded_wallets (wallet_lifecycle/bootstrap.rs:701),
• finish_unwire::register_migrated_wallets calls bootstrap_loaded_wallets().await at finish_unwire.rs:1048 and again at :1070 — the second inside the AwaitingWalletPasswords loop, i.e. after an unbounded, human-paced password prompt.

And that placement is directly at odds with the sweep's only safeguard. register_migrated_wallets runs inside drain_wallets (migration step 1); the legacy identity import is step 3, documented at finish_unwire.rs:547-549 as running last. So every time the sweep executes during a migration, the Global identity index is whatever it was before this launch's identity pass. The sweep reads "absent from the roster" as "the user removed this identity" at precisely the moment absence more likely means "not imported yet" — and a pending manifest evaluated in that window has its keys destroyed.

Suggested fix: give the sweep the same guard as the operation it completes — return early unless migration_run.try_lock() succeeds and !migration_status().state().is_in_progress(). It is best-effort and idempotent by design, so deferring to the next boot costs precisely nothing. Alternatively, move the call out of bootstrap_loaded_wallets (which the migration re-drives) into a boot-only path that runs after the identity import pass.

Static analysis only — the call chain is read from source; I did not execute a migration to watch a manifest get resumed there.

Fixed in ec23526c. Verified statically at that commit.

resume_pending_vault_cleanups now opens with the same guard pair delete_local_qualified_identity uses (identity_db.rs:1556-1567 vs :1464-1470): migration_run.try_lock() first, then a separate migration_status().state().is_in_progress() check.

The reachability that made this sharp is now closed rather than merely narrowed. finish_unwire::run holds _run_guard on migration_run (a tokio::sync::Mutex<()>, context/mod.rs:165) across run_under_guard_with_dapi_refresh → register_migrated_wallets → bootstrap_loaded_wallets → the sweep. Because try_lock() is non-blocking and the mutex is already held on that very call stack, the sweep no-ops on the in-migration path by construction — it cannot mistake "not imported yet" for "user removed this".

🟠 MEDIUM — Err no longer means "nothing was removed", and three callers still believe it does

Walked via rg over delete_local_qualified_identity across the tree (7 production call sites, 4 behaviour-bearing). Two reviewers walked it independently and landed in the same place.

The signature is unchanged; the meaning of Err is not. Before: clear_vault_keys → purge → index_remove, so a mid-flight failure left the identity still listed (with its keys destroyed — the bug you are fixing). After: manifest → index_remove → purge → vault delete, so a failure inside purge_identity_scope or the vault delete leaves the identity already off the roster while the call returns Err. Callers reading Err as "nothing changed, tell the user it failed, let them retry" are now wrong:

1. backend_task/identity/remove_identity.rs:19 — ?-propagates, so AppState raises a failure banner while the identity has in fact vanished from the hub and its keys are queued for destruction. The user is told the removal failed and simultaneously watches it succeed.
2. backend_task/identity/remove_identity.rs:24-33 — sets associated_cleanup_failed, which renders IDENTITY_REMOVED_VOTER_LEFT: "…could not be removed. Retry after restarting the app." Restarting is exactly when the new sweep completes the destruction, so after the restart there is nothing left to retry. The copy reads as "your keys are safe, try again" at the one moment they are not.
3. ui/masternodes/detail_screen.rs:1020-1034 — its rustdoc states the old contract in so many words: "keep the detail view open so the user can retry." With the identity already unlisted, that retry is a no-op at best, and the banner "This masternode couldn't be removed from this device. Try again in a moment." is now potentially false.

(wallet_lifecycle/spv.rs:87, recover_legacy_keys.rs:1070 and v093_upgrade.rs:1546 only log or collect the error — unaffected.)

Suggested fix: make the partial outcome expressible instead of collapsing it into Err. A dedicated TaskError variant (e.g. IdentityRemovedCleanupIncomplete) for the post-index_remove_identity region — the manifest already records exactly that state — lets callers say "The identity was removed. Some leftover data will be cleared the next time the app starts." At minimum, update remove_node's rustdoc, which currently documents a retry contract the code no longer honours.

_{🤖 Claudius the Magnificent · finding CALL-001}

[github-actions]

Partially fixed in ec23526c. One of the three call sites is genuinely closed; the other two are untouched.

Fixed — call site 1. remove_identity.rs:19-42 replaces the bare ? with an is_identity_listed re-check (:33): Err is only re-raised while the identity is still on the roster; otherwise it sets the new RemovedIdentities::primary_cleanup_deferred (backend_task/mod.rs:777-787), rendered as IDENTITY_REMOVED_CLEANUP_PENDING in both identities_screen.rs:1156 and hub_screen.rs:614. That is exactly the "removal succeeded, leftovers get cleared later" outcome the thread asked for. Nicely done.

Still open — call site 2. remove_identity.rs:47-58, the associated-voter-identity branch, still does a bare Err(error) => { associated_cleanup_failed = true; … } with no is_identity_listed re-check. A post-index_remove_identity failure on the voter identity still surfaces IDENTITY_REMOVED_VOTER_LEFT — "…could not be removed. Retry after restarting the app." (ui/identities/mod.rs:35) — for an identity that is already off the roster. The same false-retry advice, one branch over. The fix you already wrote applies verbatim.

Still open — call site 3. ui/masternodes/detail_screen.rs:1020-1044 is byte-identical to what the thread quoted. The rustdoc at :1022 still promises "keep the detail view open so the user can retry", and :1027-1035 raises "This masternode couldn't be removed from this device. Try again in a moment." on any Err, with no listing check. detail_screen.rs does not appear in ec23526c's diffstat at all — so even the "at minimum, update the rustdoc" floor was not met here.

🟠 MEDIUM — the "boot-time sweep" is not boot-time

Walked the call chain: resume_pending_vault_cleanups ← bootstrap_loaded_wallets (wallet_lifecycle/bootstrap.rs:701) ← three call sites:

• AppContext::ensure_wallet_backend (context/mod.rs:1174) — once per network context, so also on a mid-session network switch;
• backend_task/migration/finish_unwire.rs:1048;
• finish_unwire.rs:1070 — inside the loop { … wait_for_wallet_password().await; bootstrap_loaded_wallets().await; } that runs repeatedly while the storage migration collects wallet passwords.

Meanwhile this rustdoc says "Boot-time sweep", the call-site comment keeps the boot framing, and five tracing messages promise "will retry at next boot". None of it is true. It is a wire-the-backend sweep that also fires mid-migration and mid-session.

Two costs, and the second is the expensive one. An operator reading "will retry at next boot" waits for a restart that was never needed. And a future reader who trusts the "boot" framing will never think to check the concurrency exposure — which is exactly the exposure flagged in the two open threads about this function.

Suggested fix: describe what it is — e.g. "Sweep for vault-cleanup manifests, run whenever the wallet backend is wired" — and change the five log strings to "will retry the next time the wallet backend is wired". If boot-only execution was the actual intent, gate the call rather than describing it as such.

🟠 MEDIUM — this new durable key family is missing from docs/kv-keys.md

(Anchored here because docs/kv-keys.md is not in the diff — which is rather the point.)

docs/kv-keys.md is this repo's exhaustive key catalog: every det:* key with scope, backing store, value type and fields, closing with hard Summary counts (det-<net>.sqlite = 21 keys across 8 domains, Total 27) and an explicit rule that prefixed/templated keys count once per prefix.

This PR adds a brand-new persistent Global key family in det-<net>.sqlite — det:vault_cleanup_pending:v1:<identity_b58>, value Vec<(StoredPrivateKeyTarget, KeyID)> — and does not touch the catalog. The Identity-domain table and the counts are now wrong: the file says 21/27 where reality is 22/28.

Not a cosmetic gap. The catalog is where the next engineer goes to answer "what survives a wipe, what does the soft-cascade reap, what has to be migrated." This manifest is deliberately Global-scoped precisely so it escapes the Identity soft-cascade that the catalog documents — which is exactly the kind of exception the catalog exists to record, and right now the only place that rationale is written down is a source comment eight lines long.

Suggested fix: add a row to the Identity table for det:vault_cleanup_pending:v1:<base58_identity_id> (Scope None, store det-<net>.sqlite, value Vec<(StoredPrivateKeyTarget, KeyID)>), one sentence on why it is Global rather than Identity-scoped, a Source: pointer to src/context/identity_db.rs, and bump the Summary counts to 22 / 28.

🟠 MEDIUM — IDN-021 is tagged [Implemented], but three of its acceptance criteria describe behaviour the code does not deliver

The tag makes these bullets a contract. Three do not hold:

1. "A removal that cannot be completed leaves the identity's private keys intact, so a retry still has everything it needs and no identity is left listed without its keys." — Half true, and the wrong half is load-bearing. The keys do survive the failed attempt. But with the new ordering index_remove_identity runs before the failure-prone steps, so the identity is already off the roster and no user-reachable retry exists — as your own test name concedes: resume_pending_vault_cleanups_recovers_a_manifest_no_ui_can_reach. The keys are then destroyed unattended by the sweep. The bullet describes a retry the user cannot perform.

2. "Once the identity is gone the Settings tab moves to another identity on its own." — Only when exactly one identity remains. The hub clears the app-wide selection (hub_screen.rs:600), and effective_view(loaded_count, has_explicit_active = false, …) returns HubView::Picker for two or more remaining identities (ui/state/hub_selection.rs:26-41). The common case is landing back on the picker grid, not on another identity's Settings tab.

3. "…including the case where the identity went but a voter identity tied to it stayed behind." — The hub lists IdentityType::User identities only (resolve_selected_identity filters at context/mod.rs:1298-1302), while associated_voter_identity is set only for masternode identities in production code (ui/masternodes/list_screen.rs:913). This outcome looks unreachable from the surface the story describes.

Suggested fix: rewrite bullet 1 to state what actually happens — a removal that fails partway completes automatically later without destroying keys prematurely, with no action needed from the user. Qualify bullet 2 with the picker behaviour when more than one identity remains. Drop bullet 3 unless a User identity can in fact carry a voter identity.

These would pass a paper review and fail a real one, and bullet 1 in particular advertises a safety property the design deliberately does not provide.

Still open at ec23526c — docs/user-stories.md is untouched by every commit on this branch, and IDN-021 carries all three bullets verbatim.

One addition, because the gap widened rather than held still: ec23526c added a third user-visible outcome the story does not mention. primary_cleanup_deferred now produces its own banner (IDENTITY_REMOVED_CLEANUP_PENDING), so the criterion "the outcome is reported — including the case where the identity went but a voter identity tied to it stayed behind" enumerates two of three.

That also sharpens bullet 1. In the deferred case the removal genuinely cannot be completed, yet the user is shown a Success banner saying it was — and there is no user-reachable retry, because the identity is already off every roster. "A retry still has everything it needs" is true of the manifest, not of the user. An [Implemented] tag is what a QA pass reads, and as written it would send that pass looking for a retry control that does not exist while never testing the one branch where private keys survive a "removed" confirmation.

Suggested replacement for the last criterion — two bullets that match shipped behaviour:

• "A removal that is interrupted before the identity is delisted changes nothing: the identity stays listed with its private keys intact, and the user can try again."
• "A removal that is interrupted after the identity is delisted is reported as done, because it is — the identity is gone from every screen. Whatever data is left over is cleared automatically the next time the app opens, with no action from the user."

…and extend the outcome-reporting criterion to name all three banners. _{🤖 Claudius the Magnificent}

Review at ec23526c — 21 findings (0 critical, 0 high, 11 medium, 10 low), 5 posted inline

Three specialist reviewers went over this independently — security, project consistency, and adversarial QA — plus a separate pass re-verifying every open thread from the earlier rounds. Static analysis only: this sandbox has no warm Rust cache, so CI remains the compile-and-test backstop.

Let me start with the part that deserves saying plainly, because it is the larger part. The core of this PR is right, and it is right for articulated reasons. Reading the vault delete-set before purge_identity_scope drops the blob, persisting the manifest to DetScope::Global precisely so it outlives the purge it exists to survive, doing the irreversible step last, and clearing the manifest only after delete_all returns Ok — that sequence genuinely closes the zombie-identity hole, and the reasoning is written at the constant rather than left for the next reader to reconstruct. pending_vault_key_placements taking the union of blob and manifest instead of picking one source is the correct call. The identity_db.rs test suite is rigorous rather than decorative: it corrupts real storage instead of mocking failures, and none of it would pass against the pre-PR code.

Four previously-blocking findings verified genuinely fixed at this commit: purge-before-manifest-clear ordering (daf7c905), per-identity record-lock serialisation with the roster re-read correctly inside the lock (daf7c905), the migration guard on the sweep (ec23526c), and the primary identity's Err-semantics fix (ec23526c). I could not resolve those threads myself — this token gets FORBIDDEN on ResolveReviewThread — so I have left verification replies on each instead.

The two that should be settled before merge

Both trace to the same shape: ec23526c taught one of three callers what an Err now means.

• The voter-identity branch (remove_identity.rs:47-59) — same function, ten lines below the fix. Still classifies a deferred cleanup as a failure, so a removed voter identity produces "could not be removed. Retry after restarting the app." and keeps rendering as a live roster row. That is a zombie removal, in the PR named after abolishing them.
• The deferred-cleanup Success banner (ui/identities/mod.rs:30) — a failed private-key wipe now surfaces as a green, auto-dismissing Success describing the surviving keys as "a few remaining background files", contradicting the invariant written three lines above the call it swallows.

Also inline

• The cleanup manifest has exactly one clearing call site, so it can outlive the identity it names — and the sweep's licence to destroy keys rests on a single index read that maps absent to empty.
• The unload confirmation names no identity and does not block the breadcrumb switcher behind it. The code snapshots the target correctly; the user cannot see the snapshot.
• delete_local_qualified_identity's rustdoc still documents only the Ok contract. Two of three callers got the new Err meaning wrong, reading from a doc block that never mentioned it.

Still open from earlier rounds (unchanged at ec23526c, tracked on their existing threads)

docs/kv-keys.md has no row for the new det:vault_cleanup_pending:v1: family and its counts still read 21/27 · the sweep is still documented and logged as boot-only across eight strings while also firing on a mid-session network switch · IDN-021 is still [Implemented] with criteria that do not hold — and is now one outcome further behind, since ec23526c added a third banner the story never mentions · MasternodeDetailScreen::remove_node is untouched.

Deferral candidates — flagged, filed nowhere, so I am naming them here

• The unload confirmation promises reversibility for an action that destroys keys. Tooltip, dialog body, Danger-zone helper and IDN-021 all say "you can load it again later"; for an identity whose keys were pasted in at load time, the identity returns and the keys do not. I note the author has stated this copy fix is separately tracked — recording it as the single largest user-facing risk this PR creates, so it does not age quietly.
• Tier-2 password-protected identity key envelopes are deleted with no password check, while every read and downgrade path in the same module requires one. Pre-existing, but this PR gives it a second and more prominent entry point. Raising it explicitly because it touches stored secrets.
• The keyless-vault migration race already tracked as TODO(#889 follow-up), and the devnet-only wipe that still deletes vault keys before purging the blob.

Full report (21 findings, evidence and remediation ordering) is attached to this workflow run as report.html.

The engineering here is careful. The gap is that the final commit's insight was applied once and not propagated — which is exactly the kind of thing a shared helper and one absent unit test would have caught for you.

🟠 MEDIUM — the deferred-cleanup fix stops ten lines short, and the voter identity inherits the exact bug this commit's title abolishes

Found independently by two of the three reviewers in this pass, both walking every delete_local_qualified_identity( call site.

The block above is right, and the comment explaining it is genuinely good. Then the reasoning stops at line 43. The associated-voter delete at :47-59 — same function, next block, untouched by ec23526c — still applies the pre-fix logic: any Err, including the identical "already delisted, vault cleanup deferred" outcome you just taught the primary path to treat as success, sets associated_cleanup_failed = true.

Two consequences, and the second is the one that stings:

1. IDENTITY_REMOVED_VOTER_LEFT — "…its associated voter identity could not be removed. Retry after restarting the app." — fires for a voter identity that was removed. An alarm on a benign condition, pointing at a retry for something already gone. Restarting is precisely when the sweep finishes the job, so after the restart there is nothing to retry.
2. voter_id is pushed into removed_identity_ids only on the Ok branch (:49). Both UI consumers drop stale rows by testing membership of exactly that vector (identities_screen.rs:1143-1147, hub_screen.rs). So the already-delisted voter keeps rendering as a live, clickable row until a full reload, then silently vanishes — contradicting the warning that told the user to retry. That is a zombie roster row, which is the thing this PR is named after.

Since the voter identity holds masternode voting keys, a user who believes the removal failed has every incentive to go hunting for another way to remove it.

Suggested fix. Lift the decision out of the primary branch into something both deletes call — e.g. fn classify_delete(&self, id: &Identifier, error: TaskError) -> DeleteOutcome { Failed(error) | Deferred }, keyed on self.is_identity_listed(id).unwrap_or(true). For the voter, a Deferred outcome should push voter_id into removed_identity_ids (it is removed) and leave associated_cleanup_failed false.

Three companions worth folding into the same change:

• Decide the banner precedence. When associated_cleanup_failed && primary_cleanup_deferred are both true, the deferred-cleanup message is silently swallowed by the voter message in both identities_screen.rs:1150-1170 and hub_screen.rs:608-627. Nobody chose that; the else if did.
• De-duplicate the dispatch. Those two three-branch blocks are byte-identical across two UI domains, differing only in * derefs. You correctly extracted the strings into constants and then duplicated the branching around them. One removed_identities_banner(ctx, associated_cleanup_failed, primary_cleanup_deferred) next to the constants fixes it — otherwise the fix above has to be applied twice, which is how these two drift apart in the first place.
• Add a test. AppContext::remove_identity has no unit tests anywhere in the tree — identity_db.rs is thoroughly covered, this layer is not. A test for "voter delete fails strictly after delisting" would fail red against the current code and prove the fix once applied. That absence is, fairly directly, why this shipped inside the commit that fixed its twin.

🟠 MEDIUM — "a few remaining background files" are the user's private keys, and this ships as a green Success banner

Raised independently by the security and project reviewers.

delete_local_qualified_identity states its own contract at identity_db.rs:1501-1503, and states it well:

"Propagated, not swallowed: a vault delete that fails leaves key material on a device the user asked to clear, which is the one part of this operation they must not be told succeeded."

ec23526c swallows exactly that. When delete_all fails, remove_identity finds is_identity_listed false, sets primary_cleanup_deferred, returns Ok(…), and both handlers raise this constant as MessageType::Success with auto-dismiss (identities_screen.rs:1156-1162, hub_screen.rs:614-620).

The "few remaining background files" are the identity's raw private-key secrets in det-secrets.pwsvault, plus whatever of the Identity scope purge_identity_scope failed to drain. A user who unloads an identity as a security gesture — before selling the machine, after a suspected compromise, before handing the laptop to someone — is told the job is done, in green, and the banner then dismisses itself.

The doc comment above the constant argues the framing on the grounds that "the app finishes the cleanup automatically the next time it starts." That is conditional in ways the sentence is not. resume_pending_vault_cleanups runs only from bootstrap_loaded_wallets, only if wallet_backend() is Ok, only if migration_run is free and no migration is in progress (identity_db.rs:1556-1567) — so a launch that also runs a storage migration defers it again — and only if the vault delete succeeds that time. A persistent cause (vault file permissions, a full disk, a locked secret store) reproduces every boot, and the user is never told again; the retry path logs at warn and stops there.

To be clear about what is not in dispute: the first half of ec23526c is correct. Not claiming the identity is still present and retryable when it is already off every screen was the right call. The problem is only the second half — claiming the wipe finished.

Suggested fix

1. MessageType::Warning with disable_auto_dismiss() when primary_cleanup_deferred is true, matching how IDENTITY_REMOVED_VOTER_LEFT is already treated.
2. Copy that says what remains and what to do, per CLAUDE.md's what happened + what to do: e.g. "The identity was removed from the list, but this device could not finish deleting its saved keys. Open the app again to finish clearing them, and check that you have enough free disk space." Drop the absolute "the next time you open the app" given the migration early-return.
3. tracing::error!, not warn!, when the failing step is specifically the vault delete — a repeating failure currently has no operator-facing signal at all.
4. Update the comment at identity_db.rs:1501-1503, which now documents a behaviour the code no longer has.

🟠 MEDIUM — the cleanup manifest has exactly one clearing call site, so it can outlive the identity it names

clear_vault_cleanup_manifest is called from precisely one place: this success path (:1506). Verified by ripgrep across the tree — the definition at :1814 and this single call. Nothing in insert_local_qualified_identity, write_local_qualified_identity_locked, the legacy-recovery path, or the sweep's own skip branch retires a manifest for an identity that is still alive.

Two ways one ends up outliving its premise:

1. A removal that fails while the identity is still listed. The manifest is written at :1498, before index_remove_identity at :1499. If that index write fails — or purge_identity_scope fails and the caller aborts before delisting — the identity stays on the roster, the user gets a real error, and a manifest for a fully live identity is now permanently on disk.
2. Re-import after a deferred cleanup. Removal fails at the vault step, the manifest persists, the user later re-imports the same identity. insert_local_qualified_identity (:676) takes the record lock but never touches the manifest. The sweep then sees the identity listed and skips it (:1619-1625) — correctly, but without retiring the entry, so it sits there indefinitely.

Why that matters more than ordinary litter: the sweep's licence to destroy key material rests on one signal — load_identity_index(&kv) not containing the id (:1609-1625). And load_identity_index maps an absent index key to Ok(vec![]) (:303-308), so absence is indistinguishable from "no identities exist". For any identity carrying a stale manifest, a single lost, absent or rolled-back Global index write is then sufficient for the next sweep to purge the scope and delete_all placements that now name the live identity's secrets at the same identity_key_priv.<target>.<key_id> labels. No confirmation, no prompt, one tracing::info! line as the only trace.

I want to be fair about the exposure: this is latent, not observed. index_remove_identity has one non-test caller and I could not construct a routine flow in this tree that delists a live identity. The objection is that the safety margin is one signal wide and the manifest never expires — and the thing on the other side of that margin is irreversible.

Suggested fix

1. Clear the manifest whenever the identity is (re)written. insert_local_qualified_identity and write_local_qualified_identity_locked already hold the record lock; a clear_vault_cleanup_manifest call there is a one-liner and closes both paths above. Log a failure to clear, don't make it fatal.
2. Clear it in the sweep's skip branch too (:1619-1625). Finding the identity listed is the conclusion that the manifest is obsolete; deleting it there costs nothing.
3. Optional, defence in depth: distinguish "index key absent" from "index key present and does not contain this id", and refuse to resume on the former. An index that was never written cannot prove any identity is gone — which is the same reasoning the sweep already applies, correctly, to an index that fails to decode.

🟠 MEDIUM — the code snapshots the target correctly; the dialog does not show it, and does not block the switcher that moves it

Credit where it is due first: PendingIdentityUnload.target snapshotting the identity at click time is the right design, and take_confirmed_unload being a pure function with three unit tests around it is better than this kind of code usually gets.

The gap is that the user has no access to that snapshot. Two things compound:

1. The dialog names no identity. The body is "This removes the identity from this device…" — no alias, no Base58 ID, no distinguishing mark.
2. It does not block input. open_unload_confirmation never calls .blocks_input(true), and ConfirmationDialog defaults to blocks_input: false (ui/components/confirmation_dialog.rs:114), rendering at egui::Order::Middle with no input capture (:185-192). The hub's top panel — which hosts the breadcrumb identity switcher (hub_screen.rs:357-361, effect applied at :310 via set_selected_identity) — is a separate egui panel and stays fully clickable behind the open dialog.

So: user opens the dialog for identity A, clicks the breadcrumb to B, the entire Settings tab underneath re-renders as B, and the still-open unnamed dialog is still bound to A. Pressing "Unload" irreversibly destroys A's keys while the screen says B, and reports success.

This is not a hypothetical I invented — the PR anticipates it. The test comment at :1476-1480 says "the breadcrumb switcher stays live behind the dialog", and IDN-021's acceptance criterion says "even if the selected identity changes while the confirmation is open." The behaviour was reasoned about; the reasoning just stopped at the code and never reached the pixels. A snapshot the user cannot see is a snapshot the user cannot verify.

Suggested fix

1. Render the snapshotted target in the dialog body — alias if present, otherwise the Base58 ID (explicitly permitted in user-facing copy per CLAUDE.md rule 6). This is the actual fix: it makes the snapshot verifiable by the human rather than only by a unit test, and it also covers the plainer case where the user simply forgot which identity they clicked from.
2. Set .blocks_input(true) so the selection cannot move out from under an open irreversible-destruction prompt.

Worth considering, not blocking: ConfirmationDialog already supports required_confirmation_text. An action that permanently destroys private keys currently gets a plain one-click confirm.

🟠 MEDIUM — the new Err contract is written down inside one caller, and nowhere on the method that defines it

(Anchored at the start of your new comment block; the rustdoc in question is the doc block at :1438-1459, which is byte-identical to origin/v1.0-dev — the PR's hunk begins below it.)

The comment you added here is excellent and explains the invariant precisely. The problem is where it lives. The reorder changed the public error contract of a pub method:

• Before: index_remove_identity ran last, so an Err broadly meant "the identity is still listed."
• After: manifest → index_remove_identity → purge_identity_scope → vault delete → clear manifest. An Err from any of the last three means the identity is already delisted and gone from every screen, while the call reports failure.

remove_identity.rs:33 now depends on exactly that distinction. But the rustdoc still documents only "Returns Ok(()) even when the identity is unknown" and says nothing about Err at all. The one invariant every future caller must know is recorded as a comment in one of them.

That is not a theoretical maintenance concern — the cost has already been paid twice in this very PR. ui/masternodes/detail_screen.rs::remove_node still reads Err the old way (tracked on a separate thread), and the associated-voter branch ten lines below remove_identity.rs:43 does too. Two of three callers got it wrong, and the shared contract they were all reading from was silent.

Suggested fix — an # Errors section, well within the public-API doc budget:

/// # Errors
///
/// An `Err` does **not** mean nothing was removed. `index_remove_identity`
/// runs before the scope purge and the vault delete, so a failure in either
/// can land after the identity is already delisted and off every screen. Use
/// [`Self::is_identity_listed`] to tell the two apart; a durable cleanup
/// manifest lets [`Self::resume_pending_vault_cleanups`] finish the rest.

Cheap, and it is the only change here that stops this class of mistake recurring on the next caller.

Preliminary review — Codex only

The two prior blocking findings are fixed: recovery now re-runs the identity-scope purge and serializes the roster re-check, purge, vault deletion, and manifest clearing against same-identity writers. At the exact head, two blocking safety gaps remain: the sweep trusts a roster subject to concurrent lost updates, and the destructive confirmation neither displays its captured target nor blocks identity switching; two smaller outcome-classification and test-coverage gaps also remain.

- [BLOCKING] src/context/identity_db.rs:1629-1645: Do not authorize vault deletion from a lock-free roster entry
  The per-identity record lock prevents a same-identity re-import from racing this check, but it does not protect the Global identity index. `index_add_identity` and `index_remove_identity` at lines 320-340 are separate read-modify-write operations, and different identities use different record locks. If identity A has a retained cleanup manifest while A and B are inserted concurrently, both inserts can read the same roster; A can finish writing its vault keys and blob, then B can overwrite the roster with a value that omits A. A later sweep locks A, observes the lost roster entry, purges A's newly written blob, and deletes its keys using the stale manifest. This PR newly makes roster absence authorization for irreversible deletion, so the pre-existing lost-update behavior is now data-destructive. Serialize every `IDENTITY_INDEX_KEY` mutation with one shared lock or transactional compare-and-update primitive before relying on absence here, or bind cleanup manifests to a durable deletion generation that a fresh import supersedes.
- [SUGGESTION] src/context/identity_db.rs:1524-1526: Distinguish manifest-clear failure from remaining private keys
  When `delete_all(vault_keys)` returns successfully, every listed vault label has been deleted. If only `clear_vault_cleanup_manifest` then fails, this method still returns `Err`; `remove_identity` sees that the identity is delisted, sets `cleanup_deferred`, and both UI consumers warn that private keys remain on the device. At this boundary only an obsolete Global manifest remains, so the warning is false and the following best-effort unowned-identity tombstone is skipped. Log the manifest bookkeeping failure and continue as a completed removal. Keeping the manifest is safe because the next sweep repeats the already-successful key deletions idempotently before clearing it.

In `src/ui/identity/settings.rs`:
- [BLOCKING] src/ui/identity/settings.rs:843-856: Make the captured unload target visible and block identity switching
  `PendingIdentityUnload` correctly snapshots the identity selected when the button is clicked, but the user cannot verify that snapshot. `ConfirmationDialog` defaults to `blocks_input: false`, this dialog does not override it, and its text only says “this identity.” The breadcrumb switcher therefore remains usable behind the prompt, as the test at lines 1480-1497 explicitly models. A user can open the prompt for identity A, switch the visible Settings tab to B, and confirm an unnamed prompt that still permanently deletes A's keys. Make the destructive prompt modal and display the captured Base58 identity ID in its message.

In `src/backend_task/identity/remove_identity.rs`:
- [SUGGESTION] src/backend_task/identity/remove_identity.rs:51-88: Exercise the removal outcome classifier through its backend entry point
  No test invokes `AppContext::remove_identity`, so the safety-sensitive classification added here is unverified as a unit. Existing database tests cover deletion ordering and sweep behavior, while banner tests cover the four display combinations, but neither layer proves that a pre-delisting error propagates, a post-delisting primary error sets `cleanup_deferred`, a post-delisting voter error adds the voter to `removed_identity_ids`, or simultaneous voter failure and deferred cleanup preserve both flags. The primary and voter branches already drifted during this PR, demonstrating that lower-level tests do not catch orchestration regressions. Move or expose the existing staging support under `#[cfg(test)]` and add focused tests that call this method.

This PR newly makes roster absence authorization for irreversible deletion, so the pre-existing lost-update behavior is now data-destructive. Serialize every IDENTITY_INDEX_KEY mutation with one shared lock or transactional compare-and-update primitive before relying on absence here, or bind cleanup manifests to a durable deletion generation that a fresh import supersedes.

🔴 Blocking: Make the captured unload target visible and block identity switching

PendingIdentityUnload correctly snapshots the identity selected when the button is clicked, but the user cannot verify that snapshot. ConfirmationDialog defaults to blocks_input: false, this dialog does not override it, and its text only says “this identity.” The breadcrumb switcher therefore remains usable behind the prompt, as the test at lines 1480-1497 explicitly models. A user can open the prompt for identity A, switch the visible Settings tab to B, and confirm an unnamed prompt that still permanently deletes A's keys. Make the destructive prompt modal and display the captured Base58 identity ID in its message.

🟡 Suggestion: Distinguish manifest-clear failure from remaining private keys

When delete_all(vault_keys) returns successfully, every listed vault label has been deleted. If only clear_vault_cleanup_manifest then fails, this method still returns Err; remove_identity sees that the identity is delisted, sets cleanup_deferred, and both UI consumers warn that private keys remain on the device. At this boundary only an obsolete Global manifest remains, so the warning is false and the following best-effort unowned-identity tombstone is skipped. Log the manifest bookkeeping failure and continue as a completed removal. Keeping the manifest is safe because the next sweep repeats the already-successful key deletions idempotently before clearing it.

	crate::wallet_backend::IdentityKeyView::new(&self.secret_store, id)
	.delete_all(vault_keys)?;

🟡 Suggestion: Exercise the removal outcome classifier through its backend entry point

No test invokes AppContext::remove_identity, so the safety-sensitive classification added here is unverified as a unit. Existing database tests cover deletion ordering and sweep behavior, while banner tests cover the four display combinations, but neither layer proves that a pre-delisting error propagates, a post-delisting primary error sets cleanup_deferred, a post-delisting voter error adds the voter to removed_identity_ids, or simultaneous voter failure and deferred cleanup preserve both flags. The primary and voter branches already drifted during this PR, demonstrating that lower-level tests do not catch orchestration regressions. Move or expose the existing staging support under #[cfg(test)] and add focused tests that call this method.

Preliminary review — Codex only

The durable cleanup manifest and serialized removal path improve identity-removal safety, but two in-scope correctness gaps remain: automatic wallet discovery can resurrect an unloaded identity, and the Hub can miss its cache reset when Settings reconciles to another fallback before the result arrives. The concurrency fixtures also retain two timing-based false-green paths, and the user story overstates post-removal navigation.

- [BLOCKING] src/backend_task/identity/remove_identity.rs:51-64: Persist an unload suppression marker before reporting success
  Removal deletes the DET roster record and vault keys but records no durable indication that the user deliberately unloaded this identity. The owning wallet remains loaded, and automatic discovery runs when Platform becomes ready, after SPV reconnects, and when wallets are unlocked. `upsert_discovered_identity` inserts a discovered wallet identity whenever `get_identity_by_id` returns `None` (`discover_identities.rs:253-267`), so the next discovery pass can derive and reinsert the identity; a discovery already in progress can do so immediately after removal. This defeats the action's local-removal contract and its warning that using the identity here again requires the user's backup. Persist a per-network unload tombstone or equivalent opt-out, check it while holding the identity record lock before discovery stores the identity, and retire it only through an explicit user load.

  This test treats a 300 ms receive timeout as proof that the sweep reached and blocked on `identity_record_lock`, but the timeout establishes no happens-before relationship with the spawned thread. If the worker is delayed until after the timeout, the test re-lists the identity before the worker runs; a lock-free sweep then sees a listed identity, preserves its keys, and satisfies every remaining assertion. Add explicit test instrumentation that signals when the sweep reaches the pre-acquisition point, then verify that it cannot advance past lock acquisition until the guard is released.

In `docs/user-stories.md`:
- [SUGGESTION] docs/user-stories.md:715: Match the post-unload navigation criterion to the Hub state machine
  The acceptance criterion says the Settings tab moves to another identity automatically after removal, but clearing the explicit selection does not always do that. `effective_view` opens the remaining identity only when exactly one identity remains; it shows the identity picker when two or more remain and onboarding when none remain. Update the implemented story to describe those three outcomes instead of promising automatic Settings navigation in every case.

  (existing thread: https://github.com/dashpay/dash-evo-tool/pull/962#discussion_r3874304752)
  The result handler still derives the unload owner from mutable selection state instead of retaining the identity for which unload was dispatched. After the backend delists identity A, a UI frame can render before `RemovedIdentities` is received; `SettingsTab::ensure_selected` then reconciles its retained identity to fallback B. When the result is processed, both the explicit selection and `settings_tab.selected_identity()` can name B or be empty, so the condition misses removed A and leaves contact rows, the one-shot load guard, pending contact tasks and confirmations, and the profile cache associated with A. The current regression test delivers the result immediately and never exercises this frame ordering. Retain the dispatched unload target until its result or error arrives, or reset identity-scoped Hub state unconditionally for a removal initiated by this screen.

  `RendezvousKv` releases its first reader after 250 ms even if the expected second reader has not captured a snapshot. With the roster lock removed, a delayed second worker can therefore let the first reader time out and write before the second reads; the second then observes the completed mutation and both roster tests can pass without the lock. This contradicts the fixture's claim that every armed reader is released only after all readers hold the pre-mutation snapshot. Replace elapsed-time release with explicit worker/readiness coordination that makes the unlocked path wait until both snapshots are captured while still allowing the correctly serialized path to proceed deterministically.

Preliminary review — Codex only

The durable cleanup manifest, serialized roster writes, recovery sweep, and target-pinning fix substantially improve identity-removal safety. Two blocking defects remain: automatic discovery can recreate an intentionally unloaded identity, and the Hub can lose the cache owner when multiple unload tasks overlap; three test/documentation issues also remain.

  `pending_unload` is a single `Option`, but the unload button remains available and `AppState` spawns backend tasks independently. Dispatching unload A and then unload B overwrites A's target. The next `RemovedIdentities` result unconditionally calls `self.pending_unload.take()` without checking whether that target appears in the result's `identity_ids`; therefore A's result can consume B. If the live selection and Settings state have already reconciled away from A, A's identity-scoped caches are not reset. A pre-delisting failure for B does not clear the retained target either, leaving the tracking state stale. Track pending targets by identity or dispatch ID and consume only the target associated with the corresponding success or error, or disable further unload dispatches until the current one resolves.

  The removal path deletes the DET record and its local keys but records no durable indication that the user intentionally unloaded this identity. The owning wallet remains loaded, and automatic discovery runs when Platform becomes ready, after reconnects, and when a wallet is unlocked. `upsert_discovered_identity` inserts any wallet-derived identity for which `get_identity_by_id` returns `None`, so a later discovery pass—or one already in flight—can recreate the record immediately after removal. The per-identity record lock serializes the writes but cannot distinguish discovery from deliberate user intent; whichever operation acquires it last wins. Persist a per-network unload tombstone, check it under the identity record lock before discovery inserts the identity, and clear it only through an explicit user load.

  The timeout was removed, but the rendezvous now accepts the process-global `IDENTITY_INDEX_LOCK_CONTENDERS` count as proof that this test's missing worker is blocked. Rust unit tests run concurrently, and any other identity-index operation can transiently increment that counter. The first reader can therefore be released before this test's second worker captures its snapshot. If serialization is removed from only one roster mutation path, an unrelated contender can make the delayed worker observe the completed write and allow the regression test to pass. Scope the readiness signal to this rendezvous or tag contenders with a test-local identifier rather than accepting every process-wide contender.

  `IDENTITY_RECORD_LOCK_REQUESTS` is process-global and monotonically incremented by every `AppContext::identity_record_lock` call in every concurrently running test. An unrelated identity operation after `requests_before_sweep` is sampled can release this loop before the spawned sweep reaches its target lock. `done_rx.try_recv()` then proves only that the worker has not finished, after which the test re-lists the identity and releases the guard. With the sweep's record-lock acquisition removed, a delayed worker could then observe the re-listed identity, preserve its keys, and pass the test. Use instrumentation scoped to this context and identity, or a test-local rendezvous emitted by this sweep immediately before its own lock acquisition.

- [BLOCKING] src/backend_task/identity/add_key_to_identity.rs:164-189: Recheck the unload state before sealing the newly added key
  For a password-protected identity, this path writes the new private key into the vault before entering the unload-aware record update. If the user unloads the identity while the task waits for its network broadcast, removal captures and deletes only the placements already present in the stored blob, then clears its cleanup manifest. The task can subsequently seal the new key at lines 164-174; `update_local_qualified_identity` then acquires the record lock and declines the write because the record is absent and marked unloaded. No blob or retained manifest records the new placement, and the vault cannot enumerate it through the identity model, so the private key remains permanently orphaned after an unload that was presented as deleting the identity's keys. Acquire the identity record lock after the broadcast, recheck authoritative loaded state under that lock before sealing, and hold it through the seal and locked record write. Add a regression test in which unload completes during the broadcast wait.

In `src/context/identity_db.rs`:
- [BLOCKING] src/context/identity_db.rs:1099-1126: Use roster membership rather than blob presence to reject stale writes
  Blob presence is not authoritative evidence that a marked identity is still loaded. Removal writes the unload marker and delists the identity before `purge_identity_scope`, whose first fallible operation deletes the blob. If that delete fails—or the process stops between delisting and purging—the identity is absent from the authoritative roster while its blob remains. A stale transfer, withdrawal, top-up, add-key, refresh, or similar task then sees `existing.is_some()`, bypasses this guard, rewrites the blob, and calls `index_add_identity`, undoing an unload already reported as complete. The cleanup sweep subsequently sees the identity listed and deliberately retains its manifest and keys. Classify a marked identity using roster membership under the record lock rather than blob presence; this also lets a marker left by a pre-delisting failure be treated consistently as belonging to an identity that is still listed. Add a regression test that fails the first `purge_identity_scope` delete and verifies that a later stale update cannot re-list the identity.

Because the warning does not survive restart and there is no completion confirmation, reopening during one of those conditions can remove the only warning without making the promised key-deletion attempt.

Preliminary review — Codex only

The exact head fixes all four findings from the previous review: add-key persistence is serialized with unload, stale writes use roster authority, cleanup wording no longer promises a specific launch, and IDN-021 matches the Hub navigation state machine. Two in-scope blockers remain: a failed pre-delisting unload disables automatic refreshes for an identity that is still loaded, and the specific-index load path can report success without restoring a partially purged identity. The explicitly deferred devnet wipe and masternode result-classification issues remain concrete follow-ups.

In `src/context/identity_db.rs`:
- [BLOCKING] src/context/identity_db.rs:2096-2109: Keep automatic discovery active when unload never delisted the identity
  The unload marker is written before `index_remove_identity`, so an index-write failure or a process stop between those steps can leave the marker on an identity that remains on the authoritative roster with its record and keys intact. This branch suppresses every automatic discovery pass based only on that marker. The still-loaded identity therefore stops receiving wallet-discovery refreshes at startup, after unlock, and after wallet import, while the cleanup sweep correctly leaves it alone because it is still listed. Under the existing record lock, suppress discovery only when the marked identity is also absent from the roster; when it remains listed, the failed unload did not take effect and the stale marker should be retired.

- [BLOCKING] src/backend_task/identity/load_identity_from_wallet.rs:252-262: Restore specific-index loads through the user-requested discovery gate
  A removal can be interrupted after delisting but before its first scope delete succeeds, leaving the identity blob present while the roster entry is gone and the unload marker remains. `get_identity_by_id` then returns `Some`, so this explicit SpecificIndex search calls `update_local_qualified_identity`. That update intentionally declines the write because the identity is marked and off-roster, but returns `Ok(())`; this function nevertheless inserts the identity into the wallet's in-memory map and returns `IdentitiesLoaded { count: 1 }`. The user is told the load succeeded even though DET did not re-list the identity or clear its unload marker. Route this path through `store_discovered_identity` with `DiscoveryIntent::UserRequested`, as the UpToIndex path already does, so the marker is cleared and the record is refreshed or inserted atomically while preserving its alias.

🔴 Blocking: Keep automatic discovery active when unload never delisted the identity

The unload marker is written before index_remove_identity, so an index-write failure or a process stop between those steps can leave the marker on an identity that remains on the authoritative roster with its record and keys intact. This branch suppresses every automatic discovery pass based only on that marker. The still-loaded identity therefore stops receiving wallet-discovery refreshes at startup, after unlock, and after wallet import, while the cleanup sweep correctly leaves it alone because it is still listed. Under the existing record lock, suppress discovery only when the marked identity is also absent from the roster; when it remains listed, the failed unload did not take effect and the stale marker should be retired.

Suggested change

	);
	return Ok(false);
	}
	tracing::info!(
	identity_id = %identity_id,
	"Loading back an identity that was unloaded from this device, because the user asked for it"
	);
	self.clear_identity_unloaded(&kv, &id)?;
	}

	} else if !identity_is_listed(&kv, &id)? {
	tracing::debug!(
	identity_id = %identity_id,
