fix(leaderboard+prediction_market): repair builds, add penalize() + CI (#24, blocked on referral_registry) - #185
Conversation
leaderboard/src/lib.rs had an unclosed `record_bet` body left over from a bad merge: it referenced an undefined `user` variable, never closed its brace, and swallowed a stray duplicate `add_pts`/`add_bonus_pts` pair (both dead code shadowing the real, tested implementations earlier in the file — one of them unconditionally returned UnauthorizedCaller, contradicting ~90 passing tests that rely on add_pts actually crediting points). The crate could not compile. - record_bet is restored to the documented no-op stub (guarded by require_not_paused/require_market_contract/require_auth, same pattern as the other guarded entrypoints). - The dead duplicate add_pts/add_bonus_pts stubs are removed. - tests.rs: the caller-authorization test now calls try_add_pts (the add_pts client method panics on error) and is renamed test_add_pts_rejects_non_market_caller to describe what it actually checks. - ttl_tests.rs: test_min_points_and_min_slot_survive_ttl_refresh_cycle requested all 50 top-list slots in one get_top_players call, but page_size is capped at MAX_PAGE_SIZE (20), so slot 49 was never in the returned page. Split into a head/tail read, matching the pagination pattern already used elsewhere in the suite. Relevant to SPulse-Org#24: the issue's core complaint (points only ever increase, so the leaderboard is a permanent, monotonic ranking) was already addressed by the epoch-based decay system landed for issue SPulse-Org#69 — PlayerEntry/StoredStats carry a decay epoch, and every accrual path (reward/add_pts/reward_bonus/add_bonus_pts) recomputes forward from it, so an idle leader's score now shrinks and can be overtaken by an active newcomer (see leaderboard/src/decay_tests.rs, all passing). This PR does not touch that model; it repairs a build break in the exact accrual paths SPulse-Org#24 named, which was blocking that existing decay work from even compiling. cargo test -p leaderboard: 100 passed, 0 failed. Out of scope / separate pre-existing bug found while verifying this: prediction_market/src/lib.rs has its own, unrelated unclosed-delimiter merge corruption (get_governor_count) that keeps `cargo test --workspace` from finishing. Not touched here — flagging separately.

@Dayz-tech-co This PR repairs a build break and cleans up dead code, but it does not implement the decay or penalty system requested in issue #24. The description claims the decay system already exists from issue #69, but the diff contains no such code or tests. Please include the actual decay implementation and tests, or clarify how the existing code already addresses the issue. Also, CI status is 'none' — please provide evidence that the crate compiles and tests pass.

@Muyideen-js thanks for the review — pointers below so you can verify directly rather than take my word for it. The decay system isn't in this diff because it isn't new — it's already on
What this PR actually does, and why: at the tip of CI evidence — there's no Happy to adjust the PR title/description if "Fixes #24" reads as overclaiming — the issue's actual model change already shipped in #150, this PR just makes it buildable/testable again. Let me know if you'd rather I retitle it as a build-fix and leave #24 for the #150 author to close, or if there's a decay behavior you think is still missing that isn't covered by |

This PR repairs a build break and cleans up dead code, but it does not implement the decay or penalty system required by issue #24. The description claims decay was already shipped in PR #150, but that is not included in this diff, so the issue remains open. The test changes are reasonable, but the core requirement is missing. Please either include the decay implementation or clearly mark this as a build fix only and keep #24 open. @Dayz-tech-co

@Dayz-tech-co This PR repairs a build break but does not solve issue #24. The core complaint—points only increase with no decay or penalty—is not addressed in this diff. The PR claims decay already exists on main, but that code is not in this diff and cannot be verified from the provided evidence. Additionally, the issue explicitly requires a penalty for losses, which is not implemented. Please either include the decay/penalty changes in this PR or provide verifiable proof (e.g., a diff or test output) that they exist on main. Also, ensure CI is configured and passing. Without these, the issue remains unresolved.
…oints Issue SPulse-Org#24 lists three problems: no decay, no penalty for losses, and no way to reduce points. Decay (issue SPulse-Org#69, PR SPulse-Org#150, already on main) fixed the first by eroding a score passively over time. It doesn't address the other two: nothing in that model lets a caller take points away for a specific event the moment it happens. penalize(caller, user, pts) is that missing primitive: - Gated the same way as add_pts()/reward(): market-contract-only, paused/banned checks, require_auth. The caller trusted to award points is the one trusted to take them away. - Decay-aware: goes through stats_for_update, so a deduction lands on the player's current score, not a stale stored one. - Saturates at zero (checked via saturating_sub) instead of underflowing a u64. - Never touches won_bets/lost_bets/bonus_bets — those are activity counters recorded by whichever add_pts/reward call already reported the event; a penalty only moves points. - Only reconciles the top list if the player is already ranked. An unranked player's Stats just get a lower number — penalizing them can never be the reason they newly enter the top list or bump a ranked player out on their behalf (see test_penalize_never_inserts_an_unranked_player_into_the_top_list / test_penalize_never_evicts_a_ranked_player_on_an_unranked_players_behalf). Safety with respect to the existing top-list invariants: get_top_players and get_rank already recompute rank from live (decayed) values on every call rather than trusting stored order, and recompute_min is an unconditional full scan. A score moving down through update_top_players' existing "already listed" branch is exactly as safe as it moving up — bubble_up simply no-ops when the entry no longer beats its predecessor — so no new "sink down" logic was needed. 14 new tests in leaderboard/src/penalty_tests.rs cover: basic reduction, saturation at zero, a never-credited player, non-market caller rejection (both should_panic and try_ forms), zero-points rejection, banned-player rejection, paused rejection, activity counters left untouched, decay-awareness, rank reordering (a leader penalized below a weaker player), min-cache correctness after reordering, the two never-touch-the-top-list-for-an-outsider guarantees above, and the emitted event. cargo test -p leaderboard: 114 passed, 0 failed. Deliberately not wired into prediction_market's loss-settlement path (LOSE_POINTS) in this PR: - prediction_market has its own separate, unrelated build-breaking merge corruption (unclosed delimiter around get_governor_count) — not touched here, flagged separately. - LOSE_POINTS/LOSE_TOKENS is an intentional consolation-prize design (10 points + 2 tokens for a loss), not an oversight. Deciding whether/how much to penalize losers, and whether that should still come with a token consolation, is a product and tokenomics decision for a maintainer, not something to bundle unilaterally into a build-fix PR under review pressure. - reward()'s points>0 requirement and its interface_version-pinned cross-contract ABI (issue SPulse-Org#84) mean actually wiring this needs more care than a drive-by call-site swap. This PR ships the primitive, fully tested and safe on its own. Wiring prediction_market's loss path to use it is a natural, well-scoped follow-up for whoever makes that product call.

@Muyideen-js Pushed the real thing instead of arguing further: That covers 2 of #24's 3 listed problems directly in this PR now (penalty capability + a way to reduce points); the 3rd (decay) was already shipped in #150 before this PR existed, with evidence pasted verbatim above.

@Dayz-tech-co This PR adds a well-tested penalize() primitive and fixes a build break, but it does not fully resolve issue #24. The issue explicitly calls out that losers still gain LOSE_POINTS and that there is no penalty for losses. While penalize() provides the capability, it is not wired into the prediction_market loss settlement path, so the leaderboard still rewards losses with points. The PR acknowledges this and defers the wiring to a follow-up, but that means the issue remains open. Additionally, the decay system is claimed to be already on main, but the diff does not include it, and there is no CI to verify the local test run. Please either wire penalize() into the loss path or clearly mark this PR as a partial fix and update the issue accordingly. Also, ensure the decay code is present and tests pass in a CI environment.

@Dayz-tech-co Thank you for the detailed PR and for fixing the build break in leaderboard. However, this PR does not fully resolve issue #24. The issue specifically calls out that losers still gain LOSE_POINTS and that there is no penalty for losses. While you added a penalize() function, it is not wired into the prediction_market contract's loss settlement path. The PR description acknowledges this and notes that prediction_market does not compile on main due to three separate defects. Without integrating penalize() into the loss path, the leaderboard still awards points on losses, so the core complaint remains unaddressed. Additionally, there is no CI configuration, so we cannot verify the build in an automated environment. To fully resolve #24, please: 1) Repair prediction_market/src/lib.rs so it compiles, 2) Integrate penalize() into the loss settlement path to deduct points on losses (or adjust LOSE_POINTS semantics), 3) Add CI to ensure builds and tests pass. Once these are done, the issue can be considered fully resolved. I recommend keeping #24 open until the integration is complete.
… add CI Investigated wiring leaderboard's new penalize() into prediction_market's loss-settlement path. prediction_market did not compile on main, and not from one bug: 1. Unclosed get_governor_count body (same shape of merge corruption already fixed in leaderboard) — closed it. 2. execute_set_config had two event publishes: a working "cfg_act" event, and a second "config_changed" event referencing admin, token_contract, referral_contract, leaderboard_contract, xlm_sac — none of which are in scope in this function. Leftover merge debris. Replaced both with a single "config_changed" publish (matching the event schema documented at the top of this file) using the values actually in scope: caller (the governor who executed the change) and pending.cfg. 3. get_market_ttl() called env.storage().persistent().get_ttl(&key). Checked the SDK source directly (soroban-sdk-26.0.1/src/storage.rs): get_ttl only exists on testutils::storage::Persistent, implemented via env.host().get_contract_data_live_until_ledger(...) — a local test-sandbox capability, not something available to a contract deployed on a real network. This function could never compile for a production build; it isn't a bug so much as a feature that was never actually implementable with this SDK version's public surface. Removed it and its three dependent tests (one deleted outright; two rewritten to read TTL directly via testutils::storage::Persistent inside the test file itself, the same mechanism the contract can't use, which is exactly why it never had a production-safe path). Result: prediction_market's library target now builds cleanly. Also added .github/workflows/ci.yml, scoped to `cargo test -p leaderboard` only (currently the only target with a fully green, verifiable test suite — see the comment in the workflow for why it isn't workspace-wide yet). NOT done, and why: wiring penalize() into the actual loss path. prediction_market's *test* suite still cannot compile — tests.rs imports referral_registry::ReferralRegistryContract, and referral_registry/src/lib.rs and tests.rs are both genuinely empty (0 bytes) on main right now. Traced it: commit 670ed9b ("Merge branch 'main' into fix/issue-77") deleted 704 lines from lib.rs in a merge where both parents had identical, non-empty content — a pure accidental deletion, not a real conflict. I attempted to restore it from the pre-deletion commit and it *also* doesn't compile: require_not_paused has no closing brace and collides with an immediately-following is_paused, and register_referral contains two overlapping, half-duplicated vec![...] blocks for the welcome-bonus call (the "pause" feature was implemented independently by two branches — issue SPulse-Org#83 and issue SPulse-Org#95 — merged badly; a similar double-implementation shows up in the welcome-bonus call). That corruption predates the deletion by several commits, so this isn't a clean git-revert situation — it needs a real manual reconciliation of two overlapping feature implementations across referral_registry's history, which is a materially different and larger task than a merge repair, and not something to attempt as a drive-by part of this PR. Reverted my restoration attempt rather than leave a still-broken half-fix in the tree.

@Dayz-tech-co Thank you for the detailed PR. The addition of penalize() with tests is a solid primitive, and the CI workflow is a good start. However, this PR does not fully resolve issue #24. The core complaint is that the leaderboard is a permanent, stale ranking because points only increase and there is no penalty for losses. While penalize() provides a mechanism to reduce points, it is not wired into the loss settlement path in prediction_market. As stated in the PR description, that integration is blocked by the empty referral_registry, which is a pre-existing critical issue. Without wiring, the leaderboard still does not reflect current skill or activity. Additionally, the CI only runs cargo test -p leaderboard, so the prediction_market build break is not caught in CI. To fully address the issue, please: 1) Integrate penalize() into the loss settlement logic in prediction_market (or provide a clear plan for doing so once referral_registry is fixed). 2) Restore referral_registry to a compilable state so that the full workspace can be built and tested. 3) Expand CI to run the entire workspace once the above is fixed. 4) Provide evidence that decay is already implemented (e.g., link to the merged PR #150 and show relevant code). Without these, the issue remains open.
