# `@lssm-tech/lib.gamification-runtime`

Deterministic, immutable evaluation and replay for campaigns declared with
`@lssm-tech/lib.gamification-spec`.

The runtime expands cadence slots, evaluates conditions, streaks and capped XP,
scores leaderboards, groups leagues, applies wallet actions, reduces activities,
and canonically replays event streams. It performs no I/O and uses only explicit
timestamps, seeds, entropy receipts, and host-authorized participant references.

## Determinism and receipts

- `reduceCampaignEvent` rejects duplicate and out-of-order activities without
  mutating the input snapshot; it also rejects campaign-version mismatches,
  unknown mission slots, activity outside a slot window, and finalization before
  a slot closes. `replayCampaign` sorts by `(occurredAt, eventId)`.
- Mission XP is awarded only when an event newly completes that mission in the
  active slot. Explicit `xpRuleId` activity remains available for host-declared
  awards, and a decision exposes every receipt when one event completes several
  missions or unlocks rewards.
- XP is evaluated as base, bonuses, priority-ordered basis-point modifiers,
  rule cap, then event/source/slot/day/period/campaign caps. All rounding is
  integer half-up and each receipt reports the rule ID plus raw, applied,
  rule-capped, and later-scope-rejected XP.
- XP usage is keyed by the caller's explicit source, slot, day, period, campaign,
  and rule identifiers. Boost inventory is consumed only for a positive applied
  delta after caps.
- Slot expiry resolves completion, scheduled protection, approved excuse,
  available shield, then miss. Only completion increments a streak.
- State snapshots contain append-only XP receipts and canonical
  `gamification.*` decision events suitable for host persistence and audit.
- Recurring event/count quests evaluate against their current slot or period,
  so activity from an earlier recurrence cannot unlock a later one.

The package also exports transparent leaderboard scoring and built-in stable
tie-breakers, promotion/demotion, host/seeded/entropy-recorded matchmaking,
group streak and cooperative quest helpers, nudge cooldown decisions, and
atomic wallet grants, consumption, and transfers.
Participant IDs may identify individuals or host-authorized teams, so the same
transparent scoring function supports personal and team leaderboards.


The optional `posting-streak` surface projects unique calendar posting days with an
explicit IANA timezone and clock. Yesterday retains the active streak until the current
day ends; future posts do not count. The projection is read-only and awards no XP or
compensation. It includes a Sunday–Saturday strip with active-streak day numbering.


Posting timestamps and the clock require explicit ISO offsets; offset-free values are
not interpreted using the server's ambient timezone. Native Hirly compatibility can be
rechecked with `scripts/check-creator-streak-compatibility.ts --source-root <checkout>`.
The comparison excludes future/offset-free inputs, which deliberately receive stricter
handling in the shared projection.
