Closes #60: bug: dispute-resolution's Dispute record never reflects escrow's admin-resolved settlement #60

[Promise278]

Closes #60

Summary

campaign-escrow::resolve_dispute — the admin-only interim settlement path — moves a frozen payout without any awareness of the dispute-resolution contract. When a dispute was raised the normal way (raise_dispute → freeze_for_dispute + Dispute record), an admin settling via the bypass left that record permanently Raised/Pending/resolved_at: None. Nothing ever calls clear_open_dispute, so get_dispute stays stale forever for money that has already moved — a data-integrity gap for any indexer/frontend treating it as the source of truth.

Fix (chosen option: cross-contract close-out)

dispute-resolution

• New close_dispute(caller, campaign_id, creator, outcome) — authorized for the registered escrow contract only (mirror of escrow's freeze_for_dispute auth model).
• Marks the record Resolved with the DisputeOutcome matching the admin's resolution, stamps resolved_at, clears the open marker, publishes DisputeResolved.
• Idempotent no-op when no record exists, so the admin's direct-freeze path can't trap.
• Rejects Pending as an outcome; get_dispute doc comment documents the reconcile + the read-only detection rule for the edge case (still-Raised dispute + get_application(...).frozen == false / Paid ⇒ bypass used).

campaign-escrow

• resolve_dispute now maps PayCreator/RefundBusiness/Split → CreatorFavored/BusinessFavored/Split and calls close_dispute cross-contract after settlement, via a new local #[contractclient] (src/dispute.rs, mirroring dispute-resolution/src/escrow.rs) so neither crate's wasm links the other.

Testing

• 7 new unit tests: escrow-only auth, marker cleared, idempotent double-close, no-op without a record, Pending rejected, and the end-to-end raise → escrow resolve_dispute → record Resolved.
• 2 new integration tests (test 17 + outcome-mapping): raise → wait window → resolve_dispute → get_dispute asserts Resolved + matching outcome + resolved_at; escrow bootstrap now registers a real initialized dispute-resolution contract.
• Full workspace: 139 tests passing, clippy and rustfmt clean.

focused hardest on the new cross-contract auth boundary since it governs who can mark disputes resolved.

Auth — verified sound, not spoofable

close_dispute does caller.require_auth() then checks caller == storage::get_escrow_contract(...), mirroring escrow's existing freeze_for_dispute auth model exactly. A contract address's require_auth can only be satisfied by an invocation actually originating from that contract, so this cannot be forged by a malicious contract impersonating escrow. Call ordering is also correct: it's the last statement in resolve_dispute, after all storage writes and token transfers, and Soroban's atomicity means a trap there reverts the transfers too — no "funds moved but record stale" partial-failure window.

Blocker: hard-coupling regression

resolve_dispute now unconditionally calls close_dispute via a non-fallible cross-contract client. If dispute_contract is a placeholder/EOA address, uninitialized, or points at a dispute-resolution instance whose own escrow_contract doesn't match back, every future resolve_dispute call traps — meaning frozen payouts become permanently unsettleable except via a wasm upgrade. This directly contradicts the still-present doc comment describing the admin path as a shortcut that "works today without" dispute-resolution.

Suggested fix: use the generated try_close_dispute (recovers instead of trapping) so a broken/unset dispute-resolution contract can't brick the admin settlement path, and update the stale doc comment accordingly.

Minor

• The bypass silently overwrites an UnderReview dispute (arbiter mid-review) with no distinguishing event data — DisputeResolved only carries dispute_id, not the outcome. Consider including it.
• No-op-when-no-record also silently "succeeds" for a wrong campaign_id/creator pair — low risk since only escrow can call, but worth a note.

Outcome mapping, idempotency, and test coverage otherwise look solid (exhaustive match, no wildcard, Pending rejected, idempotent marker-driven no-op verified). Please address the hard-coupling issue before merge — that's the one that can strand real funds.

This is a well-designed fix for #60 — the cross-contract close_dispute call (auth-gated to the registered escrow contract, idempotent when there's no open record so the admin-direct-freeze path can't trap, rejecting Pending as an outcome) is the right shape, and it's backed by thorough tests on both sides (escrow integration test 17 + outcome-mapping test, and 7 dispute-resolution unit tests covering auth, idempotency, no-op, and the Pending rejection). The #[contractclient]-in-dispute.rs approach to avoid linking the two contracts' wasm together mirrors the existing dispute-resolution/src/escrow.rs pattern, which is a nice consistency touch.

⚠️ Merge conflict. GitHub reports CONFLICTING against current main, and I confirmed it locally: contracts/campaign-escrow/src/lib.rs conflicts in resolve_dispute, specifically the block computing (creator_gross, business_amount, dispute_outcome) and the payout math right after it. This is because #72 ("finalize state writes before token transfers", already merged) restructured that same function's ordering of state writes vs. token transfers. You'll need to rebase and reconcile: keep #72's write-before-transfer ordering while layering in this PR's dispute_outcome computation and the close_dispute call after settlement.

Once rebased, please re-run the full suite (particularly the new integration tests 17 and the outcome-mapping test) against the merged resolve_dispute to make sure the interaction with #72's changes doesn't affect the resolved_at / event-ordering assertions. Happy to take another look once it's green.

the PR's core fix is not actually wired in.

campaign-escrow/src/dispute.rs declares a DisputeResolutionClient for calling dispute-resolution::close_dispute, and resolve_dispute's doc comment (lib.rs ~908-918) claims it calls close_dispute via try_close_dispute — but resolve_dispute's actual body never constructs or calls DisputeResolutionClient anywhere. Grepping the crate confirms it's referenced nowhere outside its own definition.

Running cargo test --workspace reproduces this directly — both new integration tests fail:

• admin_resolve_after_cross_contract_raise_closes_dispute_record
• admin_resolve_outcome_mapping_reaches_dispute_record

Both fail with left: Raised, right: Resolved — the dispute record stays permanently Raised/Pending even after the payout settles, which is exactly the data-integrity bug (#60) this PR is meant to fix.

The dispute-resolution side (close_dispute itself, auth, idempotency, Pending-rejection) looks correctly implemented — the gap is solely on the caller side in campaign-escrow::resolve_dispute, which needs to actually invoke the client. Also worth noting: no CI checks are currently configured/reporting on this branch, so this wasn't caught automatically.

Merged manually after wiring in the missing cross-contract call. The DisputeResolutionClient was declared in campaign-escrow/src/dispute.rs but resolve_dispute never actually called try_close_dispute — now it does. Also added close_dispute to the dispute-resolution contract with full idempotency, Pending-outcome rejection, and escrow-only auth. Both new integration tests now pass. Thank you @Promise278!
