9 tasks: 1 sequential (framework helpers + fixtures) + 8 parallel (one per BackendTask group). 5 new framework helper modules with production-code staleness annotations. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Add shared OnceCell-based fixtures (SharedIdentity, SharedToken, SharedDashPayPair) and domain-specific helper modules (dashpay_helpers, token_helpers, mnlist_helpers, shielded_helpers) for backend E2E tests. Create 8 empty test stub files (core_tasks, wallet_tasks, identity_tasks, dashpay_tasks, token_tasks, broadcast_st_tasks, mnlist_tasks, shielded_tasks) with module declarations in main.rs so parallel implementation agents can work independently.

Code Review
Well-designed backend E2E test framework with thoughtful concurrency infrastructure. The main issues are: Debug string parsing for error detection (violating the project's own coding convention), a non-functional file lock on Windows, a misplaced attribute corrupting documentation, and several tests with weak assertions that could pass on stale persistent state. No true blockers after validation — original blocking severities were downgraded upon review.

In `tests/backend-e2e/framework/shielded_helpers.rs`:
- [SUGGESTION] lines 39-54: Debug string parsing for error detection violates project convention
`is_platform_shielded_unsupported()` formats the error with `{:?}` and matches ~10 substrings (`"variant 15"`, `"not implemented"`, `"corerpc"`, etc.). The same pattern appears in `dashpay_tasks.rs` at lines 328 and 731, where `format!("{:?}", e).contains("UsernameResolution")` detects retry-eligible failures.
The project's CLAUDE.md is emphatic: **"Never parse error strings to extract information. Always use the typed error chain."** The `TaskError` enum has typed variants for these cases — `TaskError::DashPay(DashPayError::UsernameResolutionFailed { .. })` exists and can be matched directly. For the shielded case, if no suitable variant exists, adding one would be more maintainable than matching 10 substrings that break on any Debug representation change.
The UsernameResolution case in `dashpay_tasks.rs:328` should be:
```rust
let is_resolution_failure = matches!(
e,
TaskError::DashPay(DashPayError::UsernameResolutionFailed { .. })
);
For the shielded helper, consider matching on TaskError variants structurally, or adding a TaskError::PlatformFeatureUnsupported variant.

The#[cfg(not(unix))]implementation oftry_lock_exclusive()unconditionally returnstrue, meaning all concurrent test processes claim slot 0 and share the same workdir, database, and SPV data directory. The project targets Windows (x86_64 per CLAUDE.md), and the entire parallelization story (pick_available_workdir, numbered slots, lock files) depends on this function providing real mutual exclusion.
At minimum, add a runtime warning so anyone running parallel E2E tests on Windows knows protection is absent. Ideally, implement Windows file locking via LockFileEx.
In tests/backend-e2e/framework/task_runner.rs:
- [SUGGESTION] lines 26-31:
#[allow(dead_code)]between doc comment lines splits the documentation
The#[allow(dead_code)]attribute on line 27 is placed between two///doc comment blocks. In Rust, attributes between doc comments split them — the summary line on line 26 ("Run a backend task with automatic retry on identity nonce conflicts.") is lost from the function's generated documentation. The attribute should be placed before or after all doc comments, not between them.
In tests/backend-e2e/dashpay_tasks.rs:
- [SUGGESTION] lines 368-377: TC-037 accepts the oldest pending request without verifying the sender
step_load_contact_requests()logsidentity_a_idbut never filters by it — it returnsincoming.first(), which is the oldest pending request (sorted by$createdAtascending percontact_requests.rs:62-66). With persistent state across runs, if a previous run crashed between send and accept, a stale request from A would sit in the queue. This run sends a new request, butfirst()picks the old one, and the new one goes unverified.
In practice the test is resilient (it handles already-established contacts), and since only identity A sends to B, the oldest request IS from A. But filtering by sender ID would make the assertion precise and prevent false positives if the test topology changes.
- [SUGGESTION] lines 62-64: Shared DashPay identity mutations use

TC-032 (tc_032_update_profile) at line 62 and TC-043 at line 724 mutate the sharedidentity_a(profile update, contact request send) using plainrun_task(). Other DashPay lifecycle steps on the same shared identity correctly userun_task_with_nonce_retry(). Since all DashPay state transitions consume the platform identity nonce, these unprotected calls can fail withIdentityNonceOverflowif the platform hasn't fully processed a prior mutation (even in serial execution, platform propagation delay can cause this). The nonce-retry wrapper was added specifically for this class of conflict — apply it consistently to all shared-identity write paths.
In tests/backend-e2e/wallet_tasks.rs:
- [SUGGESTION] lines 192-197: TC-014 and TC-079 assertions can pass on stale platform credits from previous runs
Bothstep_fetch_balances(wallet_tasks.rs:192) andtc_079_shield_credits(shielded_tasks.rs:445) assert that some platform address has a positive balance, but don't verify that the balance came from the current run's funding operation. Since the harness reuses a persistent workdir and framework wallet, leftover credits from a previous run can satisfy these assertions even if the current run's funding hasn't propagated yet.
The funding task itself does assert success (PlatformAddressFunded), so the lifecycle is partially exercised. But the follow-up assertions should compare against a baseline (balance before funding) or check the specific address that was just funded, to confirm end-to-end visibility.

Code Review
Well-architected backend E2E test suite with solid concurrency design (shared runtime, workdir locking, lazy OnceCell fixtures). The main issues are: error classification via Debug string parsing directly violates the project's stated coding convention, file-lock isolation is silently absent on Windows (flagged by all 4 review lanes), SPV wait helpers mask terminal failures by spinning to timeout, and the startup wallet purge creates an unrecoverable fund leak. Several tests also accept overly broad outcomes, reducing regression detection power.

2 additional findings
🟡 suggestion: File locking is a silent no-op on Windows — parallel test runs will corrupt shared state
tests/backend-e2e/framework/harness.rs (lines 587-591)
The #[cfg(not(unix))] fallback for try_lock_exclusive() unconditionally returns true. Every concurrent Windows test process will claim slot 0 and share the same data.db, SPV files, and wallet state, breaking the core isolation guarantee. The project targets Windows (x86_64) as a platform. There's also a duplicate doc comment on line 578. Consider implementing Windows locking via LockFileEx (the fs2 crate provides a portable try_lock_exclusive()), or at minimum emit a tracing::warn! and add a compile-time note so Windows users know they lack isolation.
🟡 suggestion: SPV wait helpers ignore terminal Error/Stopped states, turning hard failures into long timeouts
tests/backend-e2e/framework/wait.rs (lines 164-203)
wait_for_spv_running() and wait_for_spv_peers() only poll for the success condition. When SPV enters a terminal state (SpvStatus::Error or SpvStatus::Stopped), these helpers keep sleeping until the full timeout elapses (60s or 600s) and discard the actionable error from ConnectionStatus::spv_last_error(). This makes deterministic failures look like flaky timeouts and interacts badly with OnceCell retries (callers can't distinguish a dead SPV from a slow sync). Both spv_status() and spv_last_error() are available on ConnectionStatus — check for terminal states in the poll loop and return early with the diagnostic message.

In `tests/backend-e2e/framework/shielded_helpers.rs`:
- [SUGGESTION] lines 39-54: Error classification via Debug string parsing violates project convention and is fragile
`is_platform_shielded_unsupported()` formats the error with `{:?}` and searches for substrings like `"variant 15"`, `"not implemented"`, `"serializedobjectparsingerror"`. The project's CLAUDE.md explicitly states: *"Never parse error strings to extract information. Always use the typed error chain."* The `Debug` representation is an unstable diagnostic format — SDK version changes to error messages, variant renumbering, or formatting adjustments will silently change which tests get skipped vs. panicked, and CI won't catch it since the function returns `bool`. The same pattern appears in `dashpay_tasks.rs` at lines 328 and 731 (`format!("{:?}", e).contains("UsernameResolution")`). Match on `TaskError` variants structurally, or at minimum use `Display` output (which is part of the stable user-facing API) rather than `Debug`.

- [SUGGESTION] lines 161-187: Startup wallet purge makes orphaned funds permanently unrecoverable
The purge at lines 161-187 calls `remove_wallet()` (which deletes from both DB and memory) for every non-framework wallet *before* SPV starts. The later `cleanup_test_wallets()` at line 310 only iterates wallets remaining in memory — so it never sees the purged wallets and can't sweep their funds. Any balance left in a stale test wallet after a crash becomes unreachable, slowly draining the pre-funded framework wallet across runs. The chicken-and-egg problem (SPV can't sync with many wallets loaded, but you need SPV to know balances for sweeping) is real, but worth documenting explicitly. A possible mitigation: load wallets in small batches for sweep-then-delete before starting SPV with only the framework wallet.
In `tests/backend-e2e/framework/wait.rs`:
- [SUGGESTION] lines 164-203: SPV wait helpers ignore terminal Error/Stopped states, turning hard failures into long timeouts

- [SUGGESTION] lines 75-98: Duplicated `find_auth_public_key` utility — use the existing one from fixtures
`find_auth_public_key()` in `token_tasks.rs` is a verbatim copy of `find_authentication_public_key()` in `framework/fixtures.rs` (lines 347-366). The latter is already `pub` and importable. A change to key selection logic would need to be applied in both places. Replace the local copy with `use crate::framework::fixtures::find_authentication_public_key;`.
- [SUGGESTION] lines 745-772: TC-064 accepts both Ok and Err — test cannot detect regressions
TC-064 (EstimatePerpetualTokenRewards) matches `Ok(correct_variant)` and `Err(_)` as both passing. While it does panic on a wrong Ok variant, any error — including new bugs — passes silently. Since no perpetual distribution is configured, the expected behavior should be pinned: either always-error (assert `is_err()` + check the variant) or always-zero (assert Ok with amount == 0). If the behavior genuinely varies, mark the test as `#[ignore]` with a diagnostic comment rather than silently accepting all outcomes.
- [SUGGESTION] lines 798-807: TC-065 asserts `is_err()` without verifying it's an authorization error
The unauthorized mint test asserts `result.is_err()` but doesn't check the error variant. A network timeout, nonce conflict, or unrelated SDK error would also pass. Match on a specific `TaskError` variant (or at minimum verify the Display text mentions authorization/permission) to make this a meaningful negative test.

- [SUGGESTION] lines 133-148: Shared token fixture can bind to a stale contract after OnceCell retry
After `RegisteredTokenContract`, the fixture scans the DB for the first token contract whose `owner_id` matches the shared identity (line 144-146). If `SHARED_TOKEN` initialization panics after registration and `OnceCell` retries, a second contract will be registered while the first remains in the persistent DB. `find()` has no ordering guarantee, so later tests could exercise the stale contract. Consider filtering by a distinguishing attribute (e.g., creation timestamp or contract ID stored during registration) to ensure the most recently registered contract is selected.

so the block becomes ```text and satisfies markdownlint MD040.
In `@docs/ai-design/2026-04-08-backend-e2e-coverage/requirements.md`:
- Around line 179-239: The fenced dependency-tree block currently uses plain
backticks (```) and needs a language identifier for markdown linting; update the
opening fence from ``` to ```text (or another appropriate tag) for the SPV sync

docs checks.
- Around line 38-41: Update the phrasing for consistency by adding the article
"a" where needed in the requirement descriptions: change "requires funded
wallet" to "requires a funded wallet" in FundPlatformAddressFromWalletUtxos,
"Requires pre-built asset lock proof" to "Requires a pre-built asset lock proof"
in FundPlatformAddressFromAssetLock (and note it still references
CoreTask::CreateRegistrationAssetLock), "Requires two funded platform addresses
on the same wallet" to "Requires two funded platform addresses on the same
wallet" if needed add "a" where missing in TransferPlatformCredits, and change
"requires funded platform address" to "requires a funded platform address" in
WithdrawFromPlatformAddress; apply the same "requires a ..." wording to the
other occurrences mentioned (the other lines referenced in the comment).
In `@src/context/wallet_lifecycle.rs`:
- Around line 963-965: In wallet_transaction_history(), don't hardcode
WalletTransaction.is_ours to true; instead compute directionality by inspecting
the transaction inputs/outputs: set is_ours = true when the tx consumes any
UTXO/address owned by this wallet (e.g., tx.inputs.iter().any(|inp|
self.owns_address(&inp.address)) or an equivalent owns_input/owns_utxo check),
and set is_ours = false when the tx only credits our addresses (no inputs from
our wallet) so it is an inbound payment; update the WalletTransaction
construction to use that computed boolean rather than the literal true.

(e.g., a file lock using flock/fs2 or advisory lock API) around the UTXO
selection → broadcast → UTXO removal critical section or alternatively derive a
distinct funding wallet per test slot (e.g., incorporate the slot index into the
wallet mnemonic/seed) so separate processes do not share UTXOs; update the code

definitions of the same cases (TC-007, TC-008, TC-010, TC-068..TC-072) causing
duplicate/contradictory scope; update the document so there is a single source
of truth by either removing the early "removed" bullet or marking the later
detailed entries as removed/omitted accordingly, and adjust any totals/counts
and the mentions of TC-003, TC-006, TC-009 to match (search for the test IDs
TC-007, TC-008, TC-010, TC-068, TC-069, TC-070, TC-071, TC-072 and the
kept-but-failing cases TC-003, TC-006, TC-009 and make their status consistent
across the sections referenced later in the file).
In `@tests/backend-e2e/core_tasks.rs`:
- Around line 307-310: The test currently bails out silently when balance == 0
(the block that prints "TC-009..." and returns), which hides failures of the
SendSingleKeyWalletPayment path; modify the test in
tests/backend-e2e/core_tasks.rs so that instead of returning it either (a)
retries waiting for the funded balance to become spendable with a bounded retry
loop + short delay (e.g., call the existing balance check logic or a helper like
wait_for_balance) and only proceed when balance > 0, or (b) if no retry helper
is available, replace the early return with an assertion/panic such as
assert!(balance > 0, "TC-009: funding did not become spendable; failing test"),
so the test fails visibly and forces validation of SendSingleKeyWalletPayment.
Ensure you update the block that currently prints and returns to use one of
these two behaviors and reference TC-009 / SendSingleKeyWalletPayment in the
failure message for clarity.
In `@tests/backend-e2e/dashpay_tasks.rs`:
- Around line 325-327: The test currently picks a contact request by position
(incoming.first() / incoming[0]) which can choose a stale request; instead,
replace the position-based selection with an explicit selection of the
most-recent pending request by filtering incoming for the pending status and
using a max_by_key (or equivalent) on the request document's created_at (or
timestamp) field to pick the newest item, then use that tuple's request_id (the
variables referenced as request_id and _doc) in both places where
incoming.first()/incoming[0] are used.
In `@tests/backend-e2e/framework/cleanup.rs`:
- Around line 56-64: The current code derives framework_address (using
app_context.wallets().read(), framework_wallet_hash and get_receive_address)
before checking spendable and uses expect(...) while holding the wallets
read-lock, which can consume addresses for skipped wallets and panic; move the
lookup of the receive address into the actual sweep path after you confirm
spendable > 0, release the wallets read-lock before calling get_receive_address,
and replace expect(...) with non-panicking handling (Option/Result) so cleanup
remains best-effort (update the code around framework_address, the
get_receive_address call, and the spendable check/sweep logic).
In `@tests/backend-e2e/framework/fixtures.rs`:
- Around line 133-148: The lookup in shared_token() uses get_contracts(...,
None, None) and then picks the first matching qualified_contracts item, which is
non-deterministic when multiple token contracts exist for owner_id; change the
selection to deterministically pick the intended contract (for example by
passing a filter into get_contracts if available or by selecting the most recent
contract from qualified_contracts) — use owner_id and qualified_contracts as
anchors and pick the candidate with a deterministic key such as a
created/registered timestamp, block_height, or the largest/most-recent contract
id instead of taking the first match, so tests no longer bind to stale contracts
across retries.
- Around line 345-354: The doc comment says MASTER should be skipped but the
implementation in find_authentication_public_key currently includes
SecurityLevel::MASTER in the search order; fix this by removing
SecurityLevel::MASTER from the target_level array in
find_authentication_public_key (or alternatively update the doc to reflect that
MASTER is allowed) so the code and comment agree—ensure the search order only
contains CRITICAL and HIGH if MASTER must be skipped.
- Around line 46-53: Log message and doc comment for shared_identity are
inconsistent with the actual funding amount (30_000_000 duffs). Update the
tracing::info text and any preceding comment on the shared_identity function
(and any other fixture comments in this file that mention 2M/3M/10M) to reflect
"30M duffs" (or else change the numeric constant to match the written 2M/3M/10M
if you prefer to lower funding); ensure SHARED_IDENTITY usage and
ctx.create_funded_test_wallet(30_000_000) remain consistent with the updated
text.
In `@tests/backend-e2e/framework/harness.rs`:
- Around line 586-590: The current non-Unix stub try_lock_exclusive in
harness.rs returns true and thus disables isolation on Windows; change it to
either implement a real OS-exclusive lock using platform APIs (e.g., use Windows
CreateFile/OpenFile with exclusive sharing or use a cross-platform crate that
supports file locking) inside try_lock_exclusive, or make the function fail fast
(return false or panic) so the harness does not falsely assume ownership; update
any callers that expect a bool accordingly and ensure the implementation mirrors
the Unix semantics of exclusive ownership for the workdir/database/SPV slot.
- Around line 165-191: The current purge loop removes stale wallets from the DB
before SPV runs, which prevents later sweep/cleanup from recovering balances;
instead stop deleting those wallets early and defer removal until after
sweep/cleanup_test_wallets() runs: remove or disable the block that calls
app_context.remove_wallet(&hash) (and the tracing purge messages) and instead
ensure the stale list is passed through or rechecked after SPV completion so
cleanup_test_wallets() can see and sweep balances for wallet hashes !=
framework_wallet_hash while retaining use of app_context.wallets() and the
framework_wallet_hash sentinel.
In `@tests/backend-e2e/framework/shielded_helpers.rs`:
- Around line 39-54: The is_platform_shielded_unsupported function currently
inspects a Debug string of TaskError; replace that brittle substring logic by
matching on concrete TaskError variants and any structured source errors (use
match on dash_evo_tool::backend_task::error::TaskError and if needed follow
err.source() / downcast_ref to inspect underlying error types), explicitly
return true for the specific unsupported-related variants (or add a new
TaskError variant representing
unsupported/not-implemented/platform-not-supported and use that), and remove all
string contains checks so classification is done via typed matching rather than
Debug text.
In `@tests/backend-e2e/framework/task_runner.rs`:
- Around line 19-23: The live bounded receiver `_rx` is kept alive which can
block SenderAsync::send().await if many TaskResult messages are produced;
explicitly drop or drain the receiver created with tokio::sync::mpsc::channel to
close the channel and avoid blocking. Locate the `let (tx, _rx) =
tokio::sync::mpsc::channel::<TaskResult>(32);` and either call drop on the
receiver (e.g., bind as `rx` then `drop(rx)`) or spawn a background task that
continuously drains `rx` (e.g., loop on `rx.recv().await`) before calling
`SenderAsync::new(tx, ...)` and `app_context.run_backend_task(...)`, so
`run_backend_task` / `SenderAsync` cannot stall sends.
In `@tests/backend-e2e/framework/token_helpers.rs`:
- Around line 68-69: The shared token fixture currently sets contract_keywords:
vec![] which prevents keyword-based discovery tests (TC-051); update the fixture
so contract_keywords contains at least one keyword (e.g., contract_keywords:
vec!["e2e".to_string()] or similar) in the token struct initializer where
contract_keywords and token_description are set so the shared token used by the
tests includes keywords for discovery.
In `@tests/backend-e2e/identity_tasks.rs`:
- Around line 361-374: The test is asserting properties on the transient
RefreshedIdentity payload (BackendTaskSuccessResult::RefreshedIdentity -> qi)
instead of checking the persisted local state; change the test so after matching
RefreshedIdentity(qi) you reload the identity from the persistent store (use the
same store/client used elsewhere in the test to fetch by
si.qualified_identity.identity.id() or the test helper that returns the
persisted QualifiedIdentity) and assert against that persisted record (compare
id to si.qualified_identity.identity.id() and assert the persisted balance is >
0) to prove the refresh actually persisted.
In `@tests/backend-e2e/shielded_tasks.rs`:
- Around line 404-417: The test currently reuses a persistent platform address
(platform_addr / addrs[0]) and computes shielding amount from the wallet's
current total credits, which allows passing with pre-existing funds; modify the
flow so the test mints/funds fresh credits and computes the shielding amount
from the funding delta instead of the absolute total: obtain or derive a new
ephemeral platform address (or record balanceBefore via the same wallet read
path: wallets -> wallet_arc -> wallet), perform the funding action, read
balanceAfter, compute delta = balanceAfter - balanceBefore, then call the
shielding routine using delta/2; update references around platform_addr, addrs,
total_credits (or the variables used to read balances) and the shield invocation
so the test only shields credits actually funded in this run.
- Around line 46-47: The test currently always calls step_check_nullifiers()
after step_sync_notes(), which causes downstream failures when SyncNotes reports
"unsupported"; change step_sync_notes to return an explicit status/result (e.g.,
Result<(), SyncNotesUnsupported> or an enum like SyncNotesStatus) and update the
test harness to inspect that return value and short-circuit (early return or
skip remaining steps) when the status indicates unsupported; locate references
to step_sync_notes and step_check_nullifiers in the test and modify the control
flow so unsupported from step_sync_notes prevents calling step_check_nullifiers
(and any subsequent steps).
- Around line 502-513: The test currently only checks result.is_err() and
unwraps err, which lets unrelated errors pass; replace that with an assertion
that the error is the specific uninitialized-wallet variant expected by TC-083
(e.g., use assert_matches!(result, Err(MyError::UninitializedWallet{..})) or
match result { Err(e) => assert!(matches!(e,
ExpectedError::UninitializedWallet)), _ => panic!(...) }), referencing the
SyncNotes call result and the err variable, and keep the tracing::info log but
only after the typed-variant assertion succeeds so the test fails for any other
error variant.
- Around line 121-122: The skip branches currently call
shielded_helpers::is_platform_shielded_unsupported(&e) which relies on fragile
debug-string matching; instead update the error handling to detect the condition
via typed error variants or downcasting (e.g., add/use a concrete
TaskError/PlatformError variant for "shielded unsupported" or implement a helper
that downcasts the anyhow/Box<dyn Error> to that concrete type) and change the
match arms (the Err(e) branches in these tests) to call that typed check; if no
appropriate variant exists, add a new TaskError/PlatformError variant and adjust
shielded_helpers to match on that variant rather than matching on the error's
string representation.
- Around line 315-332: The test currently only logs when platform_addr is
present, so make the verification fail loudly when it's absent: inside the
BackendTaskSuccessResult::PlatformAddressBalances arm (where balances is
available from running BackendTask::WalletTask with
WalletTask::FetchPlatformAddressBalances), replace the silent if-let with an
explicit check/assert that balances.get(&platform_addr) is Some, and panic or
assert with a clear message if it's None (optionally also assert the returned
credits value meets the expected post-condition).
In `@tests/backend-e2e/token_tasks.rs`:
- Around line 39-40: Update the log message to match the actual funded amount:
change the tracing::info! call that currently says "creating funded test wallet
(10M duffs)..." to reflect the 30_000_000 duffs passed into
ctx.create_funded_test_wallet(30_000_000). Ensure the text and numeric amount in
the tracing::info! message are consistent with the create_funded_test_wallet
call.
- Around line 798-807: Replace the broad is_err() check with a concrete pattern
match against the expected authorization error: call run_task(&ctx.app_context,
task).await into result, then assert!(matches!(result,
Err(TaskError::Unauthorized{..}))) (or use the concrete error type/variant your
code uses, e.g., ApiError::Unauthorized) so only an auth failure passes; keep
the tracing::info! but use let err = result.unwrap_err() to log the actual error
after asserting its variant. Reference run_task, result, TaskError::Unauthorized
(or your project's equivalent) and tracing::info! when making this change.
- Around line 745-772: The test currently treats any Err(_) as acceptable which
hides unrelated failures; update the match on result (the variable named result
returned by the token estimation task) to assert a specific expected outcome:
either exactly the
Ok(BackendTaskSuccessResult::TokenEstimatedNonClaimedPerpetualDistributionAmountWithExplanation(iti,
amount, _)) shape with assertions on iti.token_id and a deterministic amount
(e.g., amount == 0) OR match Err(e) against the precise error variant/marker
your backend emits for "no perpetual distribution" (e.g.,
BackendTaskError::NoPerpetualDistribution or check e.kind()/code()) and assert
that variant, instead of accepting any Err; use pattern matching or matches! to
enforce the specific typed error and fail for any other Err or Ok shape
(referencing result,
BackendTaskSuccessResult::TokenEstimatedNonClaimedPerpetualDistributionAmountWithExplanation,
iti, amount, and st.token_id).
In `@tests/backend-e2e/wallet_tasks.rs`:
- Around line 342-353: The post-condition uses an if let on
BackendTaskSuccessResult::PlatformAddressBalances (in the step_transfer_credits
verification) but lacks an else to fail when verify_result is a different
success variant; update the match so that if verify_result is not
BackendTaskSuccessResult::PlatformAddressBalances you explicitly assert/fail
(panic) with a clear message, e.g. replace the if let with a full match or add
an else branch that calls panic!/assert!(false, ...) mentioning the unexpected
variant; apply the same change to the other identical block that checks
BackendTaskSuccessResult::PlatformAddressBalances later in the file so
unexpected success variants cannot silently pass verification.
- Around line 107-110: The test can pass using stale platform credits because
the funded address isn't tracked; update step_fund_platform_address to return
the exact funded PlatformAddress (in addition to WalletSeedHash or embed it in
the returned WalletSeedHash tuple) and persist it in the test context, then
change the subsequent steps that validate balances and perform transfers (e.g.,
the functions currently validating “any funded” address and the transfer step)
to accept and use that specific PlatformAddress from step_fund_platform_address
instead of querying any funded address or falling back to existing credits;
remove any fallback logic that selects a different funded source so the
fetch→validate→transfer sequence uses the same address funded in this run.
In `@tests/backend-e2e/z_broadcast_st_tasks.rs`:
- Around line 132-156: Replace the single immediate re-fetch of
Identity::fetch_by_identifier and the warning-only branch with a bounded polling
loop: repeatedly call dash_sdk::platform::Identity::fetch_by_identifier(&sdk,
identity_id).await (with a short sleep between attempts) up to a configurable
timeout/attempts, check fetched.public_keys().values().any(|k| k.data() ==
new_ipk.data()) each iteration, and fail the test (panic/expect) if the new key
is still not observed after the timeout; keep the tracing.info/tracing.warn
messages for success/final failure but ensure the test fails when visibility is
not achieved.
- Around line 260-264: The test currently only checks result.is_err() which
allows any failure; change the assertion to verify the specific rejection
variant (the TaskError typed rejection) — for example replace the assert with a
pattern match like assert!(matches!(result, Err(TaskError::InvalidNonce{..})))
or assert_eq!(result.unwrap_err(), TaskError::InvalidNonce) (or the actual
variant name and shape used in your code) so the test guarantees the
invalid-nonce rejection rather than any error.

- Around line 542-548: The test TC-030 currently only checks result.is_err();
replace that with an assertion that the error is the specific "identity not
found" variant by matching result.unwrap_err() against the expected enum/variant
(e.g., TaskError::IdentityNotFound) or using assert_matches! to assert the exact
error variant; update the assertion message to include the matched error when it
fails so the test deterministically verifies the "identity not found" contract.

…tion delay - tc_065: accept both PlatformRejected and SdkError (wrapping DestinationIdentityForTokenMintingNotSetError) as valid rejections - tc_066: add 1s sleep before re-fetch to allow DAPI node propagation Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
tc_065: match PlatformRejected or SdkError wrapping ConsensusError (DestinationIdentityForTokenMintingNotSetError). Added TODO for dedicated TaskError variant for token authorization errors. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
…ion, not auth) The token fixture has new_tokens_destination_identity: None, so the mint fails with DestinationIdentityForTokenMintingNotSetError before authorization is checked. Renamed from tc_065_mint_unauthorized to tc_065_mint_without_destination with TODO to add a proper authorization test once the fixture sets a default mint destination.

…destination, not auth)" This reverts commit 3450e6d.
…horization Token fixture now sets new_tokens_destination_identity to the owner's identity. This ensures tc_065 tests actual authorization rejection (owner-only minting rules) instead of hitting DestinationIdentityFor TokenMintingNotSetError before auth is checked.

Summary
Backend E2E test suite covering all
BackendTaskvariants with parallelization support. 59 tests across 8 test files exercising wallet, identity, DPNS, DashPay, token, shielded, and broadcast operations against a live testnet via SPV.Depends on PR #823 for production fixes (UTXO filter, IS lock relay, asset lock DB store, WAL mode). Tests compile without #823 but some will fail at runtime until those fixes land.
