fix(points): close the sock-farm, dust and end-price holes in season scoring - #138
Fixes from the points security review. They apply to the running season at the next hourly run, and only take farmed points away.
Counted holders: unverified holders count up to max(10, 2 × eligible) toward the early target, the scout fee gate and a new 10-holder gate on hold points. The same limit caps what a creator is paid for unverified holders.
Linked wallets: only $5+ from the launcher or a fee recipient before a wallet's first buy makes it an insider. Dust after a buy no longer wipes a buyer's points.
Floors and fees use each trade's stored trade-time USD.
Holdings are valued at a steady price: the median of the last trade price at the cut-off, 12 h and 24 h before. The final run uses the quote prices of the season's last hour.
Checks: unit tests, the real computeSeason on a throwaway Postgres 16 (hourly and final runs), EXPLAIN on the new price lookup (index scan).
Summary by CodeRabbit
Points Guide
Clarified that a qualifying buyer’s first purchase must meet the minimum trade value when made.
Wallets receiving at least the configured threshold of linked tokens before their first purchase do not qualify as real buyers.
Limited unverified holders counted toward token and creator rewards relative to eligible holders.
Early-buyer, holding, and fee-based rewards now require counted-holder thresholds. Holding rewards also require a minimum token holder count, and at least half of the qualifying first-buy lot must remain held.
Holdings are valued using a steady price derived from recent trade prices.
…scoring
- Counted holders: unverified real holders count up to max(10, 2 x eligible)
ones toward the early target, the scout fee gate and the new 10-holder gate on
hold points, and a creator is paid for at most that many unverified holders.
One X account plus 49 fresh wallets no longer earns early slots or 245
creator points. The best-3-per-day pick caps per token, so a crowd of
fresh wallets cannot push out a token with eligible holders.
- Linked wallets: only $5 or more from the launcher or a fee recipient BEFORE
a wallet's first buy makes it an insider. Dust after a buy can no longer wipe
a buyer's points.
- Trade-time USD: the $5 floors and fee points use each trade's stored hourly
value (bb_launch_swaps.usd), falling back to the run's price.
- Steady price: holdings are valued at the median of the token's last trade
price at the cut-off, 12 h and 24 h before, not bb_launches' last price, and
the final run uses the quotes' prices from the season's last hour.
Checked against a throwaway Postgres 16 with the real computeSeason (hourly and
final runs, hand-computed expectations) and EXPLAIN on the new price lookup.
Season scoring now uses trade-time USD values and steady-price samples. Linked-wallet eligibility checks transfer value and timing. Holder thresholds and creator payouts limit unverified holders, and the rules guide describes the updated criteria.
Season calculations retrieve indexed trade prices and hourly quote prices. They use steady-price sampling for token balances, apply final-hour quote prices where capturable, and pass stored USD values into scoring.

Scoring uses stored USD values when available. Linked transfers count only when they meet the value threshold and occur at or before the wallet’s first buy.

Holder thresholds and creator allocations cap unverified holders. Scout hold points require the minimum counted-holder total. Tests and the rules guide cover the updated criteria.

Correct the arithmetic in this test comment. The assertion passes only because of a small fee margin.
The comment says the sock token "0xa" is worth "at most 75". That is wrong. In the first-pass estimate, liveRoom = roomOf(liveBest) counts the 6 eligible fans on the other three tokens. So liveRoom = max(10, 2 × 6) = 12, and "0xa" is worth up to 12 × 7.5 = 90.
Each of "0xb", "0xc" and "0xd" is also worth 2 × 45 = 90. The tokens tie on holder points. The fans' held-buy fee points break the tie: each fan has $6 at 1% × 10 = 0.6 points, so each honest token gains 1.2. If someone changes the fee rules or constants, this test can fail for an unrelated reason. A reader of the current comment cannot see why.
Fix the comment to state the real numbers and the dependency on fee points. Alternatively, give the honest tokens a clear margin, for example 3 eligible fans each.
📝 Proposed comment fix
- // 0xa: 40 fresh wallets (worth 10 × 7.5 = 75 at most); 0xb..0xd: 2 eligible holders each (2 × 45 = 90)+ // 0xa: 40 fresh wallets, capped at the creator's room max(10, 2 × 6 eligible) = 12 → 12 × 7.5 = 90.+ // 0xb..0xd: 2 eligible holders each (2 × 45 = 90) plus 1.2 of fee points, which breaks the tie.

Correct the arithmetic in the test comment for tokens 0xa–0xd: state that 0xa’s 40 fresh wallets are capped by the creator’s room of max(10, 2 × 6 eligible fans) = 12, for up to 90 points, tying the other tokens’ 90 holder points. Note that the honest tokens win the tie through 1.2 fee points; do not change test behavior.
