Pending action tracking invofi/apps/frontend/src/components/invoices/OfferList.tsx |
OfferList tracks pending creation and acceptance operations per offer. Buttons and offer cards display operation-specific loading states. |
Optimistic offer creation invofi/apps/frontend/src/components/invoices/OfferList.tsx |
Offer submission adds a pending offer and hides the form before the contract call. Success reconciles the offer. Failure removes it and reopens the form. |
Optimistic offer acceptance invofi/apps/frontend/src/components/invoices/OfferList.tsx, invofi/apps/frontend/src/components/invoices/OfferList.test.tsx |
Acceptance updates offer and invoice statuses immediately. Success reconciles the result. Failure restores the previous statuses. Tests cover creation and acceptance outcomes. |
Estimated code review effort: 3 (Moderate) | ~20 minutes
Merge Risk: 🟡 Moderate · up to e028a
The optimistic offer and acceptance flows can lose valid offers or show reverted state after a transaction has already succeeded, potentially causing incorrect user decisions or duplicate retries. These bounded correctness issues should be fixed or explicitly accepted before merge.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Preserve optimistic offers when the initial fetch completes.
The initial Supabase fetch replaces offers with its response. If that response arrives after this optimistic insertion, it removes the pending card. Later success reconciliation maps over an offer that is no longer present, so the new offer remains absent until a reload.
Merge fetched rows with locally pending offers, or defer replacement until no creation is pending. Add a regression test where the initial fetch resolves after submission.

🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift
Do not roll back after the contract operation succeeds.
A rejected getUser or Supabase write after createOffer succeeds removes a valid on-chain offer and tells the lender to retry. A rejected mirror write after acceptOffer succeeds restores Pending in the UI even though the contract accepted the offer. A retry can then create another offer or present incorrect invoice state.
Limit rollback to the contract call. Handle mirror persistence failures separately with reconciliation, retry, or a non-rollback error message.

Hi — CI is failing due to a pre-existing bug on git fetch origin && git rebase origin/main && git push --force-with-leaseAll checks should pass after rebase. |

👋 Hey @waterWang — quick process note: please always get assigned to an issue before opening a PR. Check that the issue is unassigned, comment to claim it, and wait for it to be assigned to you before starting work. This helps avoid duplicate efforts and ensures everyone's work is coordinated. Thanks! |

Description
Implements optimistic UI for
create_offerandaccept_offer(Issue #191).Changes
submitOffer: inserts a pending offer card immediately on submit, showing a "Submitting…" badge with spinner. The card is replaced by the authoritative contract result on success, or removed with an error toast on failure. The form reopens on failure so the lender can retry with their values intact.handleAccept: applies the accepted state instantly (offer → Accepted, invoice → Financed) with an "Accepting…" badge. On contract failure, both the offer and invoice states are rolled back and an error toast is shown.Pending state indicator: a per-card "Submitting…" / "Accepting…" badge with spinner and
animate-pulsestyling (blue tones) clearly signals in-flight transactions, matching the existing ConfirmDialog/toast patterns.Double-submit protection: the Accept button disappears immediately on optimistic update (offer status flips to Accepted, which hides the Accept/Reject button group), and the Submit button is disabled while any
creatingoperation is in flight.Testing
