The PvP_Characters table tallied wins and losses but held no token balance and no purchase endpoint: earnings were client-reported (winners credited themselves locally), so verifying only a spend would have been security theater — a cheater could mint tokens by self-reporting battle wins. The server is now the ledger authority (FRE-142): registerCharacter seeds the balance from the client cache exactly once and reconciles it on every sync; battleResult requires the verified Lineage JWT bearer, rejects non-participants, and credits the winner via the reward formula ported from the client (computed from both registered rows); a new purchase mutation checks cost, balance, and cooldown in one conditional UPDATE scoped to the caller-owned row, so the spend is atomic under concurrency and rate limiting survives cold starts. Schema changes ship as an idempotent pvp-schema bootstrap (pvpTokens, ownerUserId, lastPurchaseAt), mirroring the analytics-schema pattern. Client-side counterpart shipped in the lineage repo; design record in its docs/security/pvp-server-side-purchases.md. Tests: pvp-schema (DDL + legacy-column migration + idempotency), pvp-rewards (formula parity with the client port, cost table), pvp-ledger (seed-once reconciliation, owner binding, participant verification, atomic spend, cooldown, refusal reasons) — 31 new tests against in-memory SQLite; suite 572 pass (1 pre-existing audit date-filter failure, unrelated).

/**
|
|
* PvP_Characters schema — the single source of truth for the table and the
|
|
* server-authoritative Blood Token ledger columns (FRE-142).
|
|
*
|
|
* Like VisitorAnalytics (see analytics-schema.ts), `PvP_Characters` has no
|
|
* `CREATE TABLE` in this repo — it exists only in the live Turso database.
|
|
* The definition below mirrors the columns the router reads and writes.
|
|
* The FRE-142 columns are appended via idempotent `ALTER TABLE` statements:
|
|
*
|
|
* - `pvpTokens` — the authoritative Blood Token balance. NULL means
|
|
* "not yet seeded"; the first registerCharacter call
|
|
* after this ships seeds it from the client's cached
|
|
* balance exactly once, then it is server-owned.
|
|
* - `ownerUserId` — the User.id of the authenticated owner, extracted
|
|
* from the verified Lineage JWT bearer. Purchase and
|
|
* battle-result mutations only act on rows the caller
|
|
* owns (p8-004: bind characters to authenticated
|
|
* linkIDs).
|
|
* - `lastPurchaseAt` — epoch-ms timestamp of the last committed purchase,
|
|
* used for server-side rate limiting.
|
|
*
|
|
* Pure string constants, no imports — so tests can apply them to an
|
|
* in-memory SQLite database without a network or environment.
