feat: repeat token claim as long as there are outstanding tokens

[lklimek]

Problem to solve

When an user clicks "claim" and have a big amount of credits to claim that is above Platform's limits for single claim operation, only part of awaiting tokens is claimed. The user is not notified that there are more tokens available to claim.

Solution

Claim is repeated as long as there are outstanding tokens waiting to be claimed.

Copilot's summary

This pull request introduces a new feature to handle token claims more effectively and includes improvements to error handling and logging. The main changes involve adding a new claim_all_tokens method, updating the success result type to include token claim amounts, and enhancing the user interface to display token claim results.

Token Claim Enhancements:

• Added a new claim_all_tokens method in AppContext to handle multiple token claims in a loop until no more claims are available. This method returns the total number of tokens claimed. (src/backend_task/tokens/claim_tokens.rs, [1] [2]
• Updated the BackendTaskSuccessResult enum to include a TokensClaimed(TokenAmount) variant for reporting the number of tokens claimed. (src/backend_task/mod.rs, src/backend_task/mod.rsR102)
• Modified the existing claim_token method to return the TokensClaimed result with the claimed amount instead of a generic message. (src/backend_task/tokens/claim_tokens.rs, src/backend_task/tokens/claim_tokens.rsL123-R196)

Error Handling and Logging Improvements:

• Replaced eprintln! calls with structured logging using tracing::error! for better error reporting when updating token balances. (src/backend_task/tokens/claim_tokens.rs, [1] [2]
• Enhanced error handling in the token claim process to log protocol and consensus errors more effectively. (src/backend_task/tokens/claim_tokens.rs, [1] [2]

User Interface Updates:

• Added a display_task_result method to the ClaimTokensScreen to show success or error messages based on the token claim results. This includes displaying the number of tokens claimed or an error message if no tokens are available. (src/ui/tokens/claim_tokens_screen.rs, src/ui/tokens/claim_tokens_screen.rsR251-R269)

These changes improve the robustness of the token claim process and provide better feedback to users.

Summary by CodeRabbit

• New Features

  • "Claim all" option to bulk-claim tokens from the UI with a confirmation popup
  • Displays the total claimed amount and clearer success/error statuses
  • Streamlined wallet-unlock flow for claiming tokens

• Bug Fixes / Improvements

  • Background claiming now iterates until rewards are exhausted, with improved error logging and handling for partial claims

Pull Request Overview

This PR implements a feature to execute all available token claims when a user clicks "claim" to handle situations where the platform limits prevent claiming all tokens in a single operation. The solution continuously executes claims until no more tokens are available, ensuring users can claim their full token balance.

Key changes:

• Added a new claim_all_tokens method that iterates through all available claims
• Enhanced error handling and logging with structured tracing instead of println statements
• Updated the UI to display the total number of tokens claimed

Sometimes we don't want to make all claims. We should give the user the option to do so or not.

@copilot please take over this PR, merge v1.0-dev into it, and add a checkbox "Claim all" that will control if we will repeat token claim or not, enabled by default.

140-184: ⚠️ Potential issue | 🟡 Minor

Add warning logs when document parsing fails or token_id is unavailable.

Lines 140–184 silently return claimed_amount = 0 when data_contract.token_id(token_position) is None or the claim result document lacks claimerId/amount fields. Since claim_all_tokens breaks its loop on TokensClaimed(0) (line 52), this causes on-chain successful claims to be silently discarded without retry or user notification.

Log a warning when the token_id is absent or expected document fields are missing, so claim successes aren't lost to schema changes or unexpected document structures.

139-144: TOCTOU: check-then-insert without a single atomic statement.

The SELECT COUNT and INSERT are two separate statements. Even after fixing the deadlock (using conn.execute), a concurrent thread could insert the same identity between the check and the insert, causing a constraint violation or duplicate. Consider using INSERT OR IGNORE (or INSERT ... ON CONFLICT DO NOTHING) to make this atomic, which also simplifies the code by removing the SELECT entirely.

♻️ Proposed simplification using INSERT OR IGNORE

-        // Check if the identity already exists
-        let conn = self.conn.lock().unwrap();
-        let mut stmt =
-            conn.prepare("SELECT COUNT(*) FROM identity WHERE id = ? AND network = ?")?;
-        let count: i64 = stmt.query_row(params![id, network], |row| row.get(0))?;
-
-        // If the identity doesn't exist, insert it
-        if count == 0 {
-            self.execute(
-                "INSERT INTO identity (id, data, is_local, alias, identity_type, network)
-             VALUES (?, ?, 0, ?, ?, ?)",
-                params![id, data, alias, identity_type, network],
-            )?;
-        }
+        let conn = self.conn.lock().unwrap();
+        conn.execute(
+            "INSERT OR IGNORE INTO identity (id, data, is_local, alias, identity_type, network)
+             VALUES (?, ?, 0, ?, ?, ?)",
+            params![id, data, alias, identity_type, network],
+        )?;

This also eliminates the deadlock issue from the previous comment. As per coding guidelines, SQLite uses a single connection wrapped in Mutex<Connection>, so the INSERT OR IGNORE approach is safe and idiomatic.

38-80: Unbounded loop — consider adding a safety limit.

The loop relies on the platform eventually returning zero or a consensus error to terminate. If something unexpected happens (e.g., a bug where the claimed amount never reaches zero, or transient network issues that cause partial success states), this could loop indefinitely. A max-iteration safety guard would improve robustness.

I think I'd rather we just claim the max amount, and show to the user they may need to claim again? It seems a bit strange and maybe error prone potentially.

Code Review

Repeated token claiming loop is well-motivated but has an unbounded loop with no iteration limit, and the fee display shows single-claim cost even when claim_all may submit many transitions. Both agents converge on the infinite loop risk.

  The `loop` in `claim_all_tokens` has no upper bound.

iterations is explicitly typed as usize and then passed to estimate_document_batch(iterations). If estimate_document_batch expects a fixed-width integer (commonly u16/u32 for “count”), this will fail to compile because Rust won’t implicitly convert from usize. Use the same type that estimate_document_batch expects (or convert explicitly with a checked/limited cast) to avoid a compile error and potential truncation.

The doc says this “accumulat[es] fees across iterations,” but the implementation doesn’t accumulate returned fees from each successful claim_tokens call; it discards per-iteration fee results and re-estimates once at the end based on iterations. Either update the documentation to describe “re-estimates total fee based on number of iterations,” or change the implementation to actually aggregate the fee results returned by claim_tokens.

[Copilot]

The PR description and metadata mention returning/reporting the total number of tokens claimed (and introduces BackendTaskSuccessResult::TokensClaimed(TokenAmount)), but claim_tokens still returns ClaimedTokens(FeeResult) and does not report claimed amount. If the intended user-visible outcome is “X tokens claimed,” this function (and claim_all_tokens) should return the amount (likely via TokensClaimed) or the PR description should be updated to reflect that only fee info is returned.

[Copilot]

Defaulting claim_all to true changes the default behavior from single claim to potentially multiple sequential claims, which can increase time-to-complete and total fees/requests. If this is not intended as a breaking UX change, consider defaulting to false (preserving current behavior) or persisting the user’s last choice so they opt into claim-all explicitly.

Suggested change

	claim_all: true,
	claim_all: false,

Code Review

Claim-all loop logic is sound but has three notable issues: (1) the total-fee calculation uses a default PlatformFeeEstimator and silently diverges from the per-claim figure the UI shows when the network multiplier isn't 1x, (2) reaching the 1,000-iteration safety cap returns plain ClaimedTokens success with no signal to the UI that tokens may still remain, and (3) there are no unit tests for the new termination, first-iteration error, and cap-break branches. A couple of smaller architectural nitpicks (dead Ok(other) arm, dual-role NoTokensToClaim, claim_all defaulting to true) are also worth noting.

In `src/backend_task/tokens/claim_tokens.rs`:
- [SUGGESTION] lines 180-183: Total fee ignores the cached network fee multiplier
  `PlatformFeeEstimator::new()` uses the default 1x multiplier, while `AppContext::fee_estimator()` (src/context/mod.rs:528) wraps the cached `fee_multiplier_permille` that is updated from epoch info. The claim screen already uses `self.app_context.fee_estimator()` for the per-claim preview (src/ui/tokens/claim_tokens_screen.rs:576), so whenever the active multiplier isn't 1x the success total returned here will systematically disagree with what the user saw moments earlier. Switch to `self.fee_estimator()` so the aggregated fee respects the active multiplier. (The pre-existing single-claim path at line 110 has the same bug and should be updated together.)
- [SUGGESTION] lines 145-184: Hitting the iteration cap is indistinguishable from full success in the UI
  When `iterations >= MAX_CLAIM_ALL_ITERATIONS` the function logs `warn!` and then falls through to `Ok(BackendTaskSuccessResult::ClaimedTokens(...))`. The banner the user sees is identical to a normal completion (`Claimed Successfully!`), so if the cap ever fires — e.g. a misbehaving node or SDK bug that never surfaces `NoTokensToClaim` — the user is told "Claim all" finished even though rewards may remain. The doc comment says the user can press Claim again, but nothing in the returned result or the UI indicates they should. Prefer adding a dedicated success variant (e.g. `ClaimedTokensPartial { iterations }`) and surfacing a warning banner at the call site so the partial-completion case is observable in the UI, not only in the log.
- [SUGGESTION] lines 132-184: `claim_all_tokens` has no unit-test coverage for its new branches
  The loop introduces four load-bearing branches: first-iteration `NoTokensToClaim` is propagated as an error; later `NoTokensToClaim` breaks with an aggregated fee; any other error short-circuits; the 1,000-iteration cap breaks and still reports success. None of these are covered by an inline `#[test]` in the file, and a grep of `tests/` shows no `claim_tokens` / `claim_all_tokens` coverage (`tests/backend-e2e/token_tasks.rs` exercises other token operations but not claim). CLAUDE.md calls out that new backend tasks should have unit-test coverage, and this is exactly the kind of control flow where regressions are easy to miss. Consider extracting the termination logic behind an injected `claim_once` closure (or a small trait) so the three exit paths can be unit-tested without standing up the real SDK and DB.

🟡 Suggestion: Total fee ignores the cached network fee multiplier

PlatformFeeEstimator::new() uses the default 1x multiplier, while AppContext::fee_estimator() (src/context/mod.rs:528) wraps the cached fee_multiplier_permille that is updated from epoch info. The claim screen already uses self.app_context.fee_estimator() for the per-claim preview (src/ui/tokens/claim_tokens_screen.rs:576), so whenever the active multiplier isn't 1x the success total returned here will systematically disagree with what the user saw moments earlier. Switch to self.fee_estimator() so the aggregated fee respects the active multiplier. (The pre-existing single-claim path at line 110 has the same bug and should be updated together.)

🟡 Suggestion: Hitting the iteration cap is indistinguishable from full success in the UI

When iterations >= MAX_CLAIM_ALL_ITERATIONS the function logs warn! and then falls through to Ok(BackendTaskSuccessResult::ClaimedTokens(...)). The banner the user sees is identical to a normal completion (Claimed Successfully!), so if the cap ever fires — e.g. a misbehaving node or SDK bug that never surfaces NoTokensToClaim — the user is told "Claim all" finished even though rewards may remain. The doc comment says the user can press Claim again, but nothing in the returned result or the UI indicates they should. Prefer adding a dedicated success variant (e.g. ClaimedTokensPartial { iterations }) and surfacing a warning banner at the call site so the partial-completion case is observable in the UI, not only in the log.

🟡 Suggestion: claim_all_tokens has no unit-test coverage for its new branches

The loop introduces four load-bearing branches: first-iteration NoTokensToClaim is propagated as an error; later NoTokensToClaim breaks with an aggregated fee; any other error short-circuits; the 1,000-iteration cap breaks and still reports success. None of these are covered by an inline #[test] in the file, and a grep of tests/ shows no claim_tokens / claim_all_tokens coverage (tests/backend-e2e/token_tasks.rs exercises other token operations but not claim).

💬 Nitpick: Ok(other) arm silently discards already-broadcast claims

claim_tokens only ever returns BackendTaskSuccessResult::ClaimedTokens, so the Ok(other) => return Ok(other) arm is effectively dead today. If another variant is ever added, returning it here throws away every claim already broadcast in the loop — the user sees an unrelated result and has no indication real transactions were paid for. Either turn this into a debug_assert!/unreachable! to make the invariant explicit, or log a warning and still fall through to the accumulated ClaimedTokens result. Low impact now, cheap to harden.

💬 Nitpick: NoTokensToClaim conflates user-facing error with loop-termination signal

TaskError::NoTokensToClaim is documented as both a user-facing error (its #[error] text is rendered in MessageBanner) and an internal termination signal for claim_all_tokens. Future refactors of claim_tokens that legitimately return this variant mid-loop would silently change the aggregated semantics. A cleaner shape is to have claim_tokens return a typed enum ClaimOutcome { Claimed(FeeResult), Empty } on Ok, reserving TaskError for real failures, and map Empty explicitly into the first-iteration error at the outer call site.

💬 Nitpick: claim_all defaults to true on every screen open

Even with the new confirmation dialog and "Claim all may submit several transactions" disclaimer, the checkbox resets to true on every visit — a user who unchecks it today will see it re-checked next time. Defaulting to false (explicit opt-in) or persisting the preference alongside other settings would reduce the chance of an accidental multi-fee claim for users who habitually click Claim without reading the dialog. UX judgement call.

Code Review

The new claim_all loop has two real correctness issues: the consensus-error predicate matches only one SDK error wrapper while the rest of the codebase checks both, and a mid-loop failure after one or more successful iterations is reported to the user as a plain error, hiding partial on-chain state changes and already-spent fees. The aggregated success result also discards iteration count and cap-hit signal, leaving the UI unable to communicate partial completion. Multiple agents flagged the absence of any test coverage for this consensus-adjacent state-transition loop, which CLAUDE.md explicitly requires.

- [BLOCKING] lines 198-207: `is_no_current_rewards_error` only recognizes one of the two SDK wrappers used elsewhere in this crate
  The predicate that decides whether `claim_all_tokens` can terminate cleanly only matches `SdkError::Protocol(ProtocolError::ConsensusError(...))`. Every other consensus-cause check in this crate handles both wrappers — see `is_instant_lock_proof_invalid` (src/backend_task/error.rs:1037) and `shielded_broadcast_error` (src/backend_task/error.rs:1106), each of which also unpacks `SdkError::StateTransitionBroadcastError(broadcast_err) => broadcast_err.cause.as_ref()`. If `InvalidTokenClaimNoCurrentRewards` is delivered through the broadcast wrapper (which is the path most state-transition rejections take in this codebase), `claim_tokens` will fail to produce `TaskError::NoTokensToClaim`, the loop will mis-classify the terminal condition as a hard error after partial success, and the single-claim path will bypass the friendly "nothing to claim" banner. Widen the matcher to mirror the existing convention and add a unit test for both shapes so future SDK refactors fail loudly instead of silently degrading.
- [BLOCKING] lines 164-177: Mid-loop error after successful iterations is reported to the user as a full failure
  When iteration N succeeds (state transition broadcast and committed, fee paid) and iteration N+1 fails with anything other than `NoTokensToClaim`, `claim_all_tokens` returns `Err(e)`. `ClaimTokensScreen::display_task_result` only transitions to `Complete` on `BackendTaskSuccessResult::ClaimedTokens`, so the user sees a generic error banner with no signal that earlier claims already committed on-chain and consumed credit fees. A retry will then perform fewer iterations than expected, looking like a separate failure. Either return a partial-success success-result variant carrying the iteration count and the underlying error for warning display, or have the loop surface successful iterations through a tracing/banner channel before propagating the error so the user can self-resolve ("X claims succeeded, then we hit a problem — please retry to claim the rest"). Today the doc comment promise ("Any other error short-circuits the loop") translates into UX that hides on-chain state changes from the user.
- [SUGGESTION] lines 142-194: Aggregated success result hides iteration count and cap-hit state from the UI
  `claim_all_tokens` returns the same `BackendTaskSuccessResult::ClaimedTokens(FeeResult)` shape as a single claim, with no field for `iterations_run` or `hit_cap`. Two consequences:

1. **Cap path silently truncates legitimate use.** The doc comment itself states fixed-amount distributions can have up to 32,767 cycles per call, but `MAX_CLAIM_ALL_ITERATIONS` is 1,000. A genuinely large fixed-amount backlog hits the cap, logs a warning, and returns the same success shape as a fully drained loop. The user has no signal to press Claim again — the success screen shows "Claimed Successfully!" with no indication more remain. Either raise the cap above the documented maximum (relying on `NoTokensToClaim` for normal termination) or surface the cap-hit state.
2. **Identical UX for 1 vs 1000 transactions.** The user cannot tell from the success screen how many claims actually ran or what they paid in aggregate.

Introduce a dedicated success variant such as `ClaimedAllTokens { iterations: usize, hit_cap: bool, fee: FeeResult }` so the UI can communicate partial completion and prompt the user to retry, matching the typed-success surface the rest of the codebase relies on for accurate user messaging.
- [SUGGESTION] lines 132-207: New loop, predicate, and termination semantics ship without any tests
  CLAUDE.md states: "Changes to consensus-adjacent logic (fee calc, state transitions) MUST have tests." The new logic includes the `is_no_current_rewards_error` predicate, the loop-termination behavior (first-call no-rewards propagated, later no-rewards swallowed), the iteration-cap path, fee accumulation, and propagation of unexpected `Ok` variants — none of which has unit, integration, or UI coverage. The predicate in particular is straightforward to unit-test by constructing each enum shape (and would have caught the wrapper-match issue above). The loop semantics can be covered by extracting the iteration body into a closure-injected helper and asserting termination across all five branches. Without tests, future `SdkError`/`ConsensusError`/`StateError` refactors will silently regress termination since `matches!` degrades to `false` rather than producing a compile error.
- [SUGGESTION] lines 142-184: Long-running claim-all loop has no progress reporting or cancellation
  Each iteration is a full platform state-transition broadcast plus proof verification — easily multiple seconds per call. With a 1,000-iteration cap, the worst-case task duration is in the multi-minute range with an unchanging banner and no cooperative cancellation point if the user navigates away. Other long-running backend tasks in the codebase emit incremental `TaskResult::Refresh`/progress updates. Consider sending an intermediate progress message after every N iterations or honoring a cancellation token from `AppContext`. At minimum, document that this task cannot be interrupted once started.

Code Review

Two real correctness issues in the new claim_all loop survive at this head: is_no_current_rewards_error only matches one of the two SDK error wrappers handled elsewhere in this crate, and a mid-loop failure after one or more committed claims is collapsed into a plain Err, hiding partial on-chain state and consumed fees from the UI. The aggregated success surface also cannot distinguish a fully-drained run from a cap-hit truncation, and the new consensus-adjacent loop ships with zero tests despite CLAUDE.md's explicit requirement.
