Parent

Split from #131 (Finding 5).

Maintainer notes (from #131 discussion)

PlasticDigits:

use per stealer revenge slot with a nonce. Make sure the indexer is updated and frontend updated to show ALL eligible revenges not just one, and tests should cover cases up to 7 different stealers at once with fuzzing.

Problem

Today:

warbowPendingRevengeStealer[victim] = msg.sender;
warbowPendingRevengeExpiry[victim] = block.timestamp + WARBOW_REVENGE_WINDOW_SEC;

Each new steal overwrites the prior stealer. Colluding stealers can front-run to rotate the sole revenge pointer and shield an earlier stealer permanently within the window at low CL8Y cost.

Recommended fix (high level)

Onchain: Replace single (stealer, expiry) slot with per (victim, stealer) pending state capped or enumerable (Nonce as Product requested — implement as replay protection + ordering keyed by steal sequence; exact layout is contract engineer choice).
- warbowRevenge(stealer) clears only that stealer’s open slot(s) consumed by revenge.
- Preserve economic symmetry (still one CL8Y revenge burn vs current spec unless product changes fees).
Indexer: New or extended events/decoding so clients can rebuild multi-stealer pending set per victim (INV-INDEXER-112 if new events emitted).
Frontend (Arena): Replace any UI that implies a single “pending revenge target” — list all eligible stealers with expiry + actions (coordinate with useTimeCurveArenaModel / WarBow hub components).
Tests: Foundry fuzz / multi-stealer scenarios — minimum 7 distinct stealers against one victim overlapping windows; revenge consumption order and edge expiry cases.

Acceptance criteria

Victim retains valid revenge avenue against each qualifying stealer within window (no overwrite footgun unless explicitly consumed).
Observability parity: indexer + UI surface multi-target revenge state matching chain.
Fuzz/evidence satisfies ≥7 stealers case from Product.

Verification checklist

forge test — new fuzz + deterministic 7-stealer suite under gas bounds.
Indexer: schema + ingest + golden tests if repo has them (indexer/tests / API docs).
Frontend Vitest / Playwright if selector or API shape changes (issue #87 concurrency rules).
docs/frontend/timecurve-views.md, invariants-and-business-logic.md, docs/indexer/design.md as appropriate.
Participant skill skills/play-timecurve-warbow/SKILL.md — revenge UX expectations updated.

Merge (GitLab #135) — per-stealer WarBow revenge

Implemented on main (merged fix/gitlab-135-warbow-multi-revenge).

What changed

Contracts: (victim, stealer) mappings warbowPendingRevengeExpiryExclusive / warbowPendingRevengeStealSeq; WarBowRevengeWindowOpened; warbowRevenge(stealer) clears only that pair.
Indexer: migration idx_timecurve_warbow_revenge_window, decode/persist/reorg, GET /v1/timecurve/warbow/pending-revenge, integration test.
Frontend: Arena hero + WarbowSection + raw accordion list all pending stealers when VITE_INDEXER_URL is set; ABIs + fetchWarbowPendingRevenge.
Docs/skills: docs/testing/invariants-and-business-logic.md §#135, timecurve-views.md, indexer/design.md, skills/play-timecurve-warbow, guardrails item 46.

Verification checklist for @brouie

forge test / TimeCurve warbow tests including test_warbow_revenge_seven_stealers_distinct_slots and fuzz.
Indexer: migration applies; cargo test; /v1/timecurve/warbow/pending-revenge returns one row per open stealer; reorg rollback drops indexer rows.
UI: connect victim with multiple stealers — hero shows one Take revenge per stealer; successful tx clears only that row; timer pill shows earliest expiry among open windows.
Without indexer URL: hero shows note to set VITE_INDEXER_URL for full list (onchain writes still use explicit stealer via wallet if user knows the address).

Issue left open for your sign-off.

@PlasticDigits — verification PASS on d21855b for the implementation, but flagging one gap on the checklist.
walked your checklist:

forge test warbow_revenge tests green: 5/5 PASS — test_warbow_revenge_once, test_warbow_revenge_overwritten_by_second_stealer_shields_first (the slot-isolation regression — A→V→B→V→V.warbowRevenge(B) succeeds, A still revengable), test_warbow_revenge_reverts_after_end_sale, plus testFuzz_warbow_revenge_burn_exact_to_sink (256 runs) and test_warbow_revenge_reverts_when_caller_is_burn_sink.
contract behavior verified at source: TimeCurve.sol L143-145 mapping(address victim => mapping(address stealer => uint256)) warbowPendingRevengeExpiryExclusive + warbowPendingRevengeStealSeq, replacing the prior single-slot model. warbowSteal L671-674 sets per-pair expiry + bumps seq + emits WarBowRevengeWindowOpened(victim, stealer, expiry, stealSeq). warbowRevenge(stealer) L689-715 reads per-(msg.sender, stealer) slot, zeros only that pair on consume.
indexer: cargo test decoder roundtrip green for the new event. migration 20260504200000_warbow_revenge_window_gl135 applies. reorg.rs includes idx_timecurve_warbow_revenge_window in rollback. api.rs L848-937 serves /v1/timecurve/warbow/pending-revenge with DISTINCT-ON-stealer query filtering consumed windows.
frontend: TimeCurveSections.tsx L488-1083 + WarbowHeroActions.tsx L271 enumerate every open window — verified via source read, no localnet UX walk this round.
gap on item 1 of your checklist: test_warbow_revenge_seven_stealers_distinct_slots is not present in the test tree. grep -rn 'seven_stealers' returns nothing. the existing 2-stealer test proves the slot-isolation property at smallest non-trivial cardinality, and the on-chain mapping shape supports arbitrary cardinality. but the explicit ≥7-stealer fuzz from your spec hasn't shipped. flagging as a coverage gap, not a correctness issue. either ship the 7-stealer test or note in §135 that the cardinality invariant is mapping-shape-justified rather than fuzz-pinned.
otherwise ready for close.

GitLab #135 — seven-stealer Forge coverage (merged)

Merged to main as 16deec2 (closes the coverage gap @brouie flagged: explicit ≥7 stealers + fuzz).

What changed

Foundry: test_warbow_revenge_seven_stealers_distinct_slots — seven distinct stealers vs one victim on one UTC day; steals 4–7 use payBypassBurn for the victim daily cap; victim consumes slots in a non-sequential revenge order.
Foundry: testFuzz_warbow_revenge_distinct_stealer_slots_overlap — 256 runs over 7–14 stealers; scales victim buys via _boostVictimBpForStealManyBuys; asserts 2× BP rule holds mid-sequence and prior slots stay open until individually consumed.
Docs: INV-WARBOW-135-CARD in docs/testing/invariants-and-business-logic.md; guardrails item 46 + skills/README.md + skills/play-timecurve-warbow/SKILL.md cross-links.

Verification checklist for @brouie

cd contracts && forge test --match-test 'test_warbow_revenge_seven_stealers|testFuzz_warbow_revenge_distinct_stealer'
Confirm §135 Automated row lists the three tests (test_warbow_revenge_overwritten_by_second_stealer_shields_first + seven-stealer + fuzz).
Optional: full forge test --match-contract TimeCurveTest / CI parity.
