Module-uo/server/config/shardTriggers.js

// ── module-uo's engagement triggers ────────────────────────────────────────
//
// ENGAGEMENT.md §8.6 and Phase 11. The twin of `config/shardStreams.js`: that
// file declares which shard events a player may get a content-free PUSH tickle
// for, and this one declares the PAYLOAD CONTRACT behind an event — what a rule
// may fire on, what a template may interpolate, and the widest audience an
// operator may ever give it.
//
// **One namespace, two facets** (§7.2, the org lead's Phase 2 decision). A
// trigger id and a stream id live in the same space and an id has exactly one
// owner across both, so the seven grandfathered stream ids in `shardStreams.js`
// (`idoc.warning`, `house.idoc`, …) are ALSO this module's for trigger purposes.
// Nothing below reuses one: the trigger ids here are the `uo.*`-prefixed names
// §8.6 specifies, and they are new. A trigger-only id gets email and in-app
// preferences and no push toggle, which is correct — `allStreams()` serves the
// stream facet only, so the shipped Android client's catalog is unchanged.
//
// **Every ✅ row of §8.6 is here except four, and each carve-out is recorded**
// in ENGAGEMENT.md §8.6 with its reason rather than being silently absent:
//
//   • `uo.market.item_listed` — a saved SEARCH, not a trigger. Its audience is
//     "users whose stored query matches this listing" and no per-user query store
//     exists anywhere in the tree.
//   • `uo.guild.joined` — core's `team.member.joined` already fires for it. A UO
//     guild IS a Team and this module is the Team provider, so `teamSync` emits
//     on every roster reconcile; a second trigger would be two mails for one join.
//     `uo.guild.left` and `uo.guild.disbanded` DO ship — core has neither.
//   • `uo.link.requested` — no addressable recipient by construction (the account
//     is not yet linked, which is the point of the event) and a ~5-minute TTL no
//     channel can beat.
//   • `uo.points.rank_changed`'s personal half — `points.board`'s `top[]` names a
//     mobile SERIAL and `shard_account_links` is keyed by ACCOUNT. The board-change
//     feed ships at `subscribers`; "you were pushed out" does not.
//
// **Three rules every declaration below obeys, all of them enforced at
// registration** (`registries.js`), so a mistake here is a boot failure rather
// than a defect discovered in someone's mailbox:
//
//   1. **`ceiling` is required and there is no default.** It is the widest
//      audience a rule may ever be given (G24), re-checked at save AND at send.
//      `uo.cheat.detected` is why the lattice exists: `owner` would mail the
//      cheat report to the player who was detected, and `staff` is the answer.
//   2. **Every variable carries an `example`.** It is what the template editor
//      previews and test-sends with; without one, testing a template needs a live
//      game event, which is how template systems ship untested (§4.3 property 3).
//   3. **A `url` variable is site-RELATIVE** and validated as such. A payload
//      value ends up in an href in an email, and `//evil.test/x` passes an "is it
//      rooted" check while being protocol-relative.
//
// **Nothing here emits.** `utils/shardEngagement.js` is the mapper that turns a
// wire frame into a call; this file is only the contract. Keeping them apart is
// what lets the declarations be read as a catalogue and diffed against §8.6.

// Every trigger's `version`. Bumped per declaration when a variable's MEANING
// changes, not when one is added — an added optional is what `required: false`
// is for, and a stored rule keeps working across it.
const V1 = 1


// ── The presentational fragments (Phase 11b, decision 8) ────────────────────────
//
// Sixteen of these triggers render through an IN-UNIVERSE body — a letter from
// the Office of Deeds, a herald's notice, a dispatch from Lord Blackthorn's
// court. A letter is a sentence, and a template has no conditionals by design
// (`interpolate.js`), so an unset optional interpolates to the EMPTY STRING and
// leaves a hole mid-clause: "The house , in , stands in peril."
//
// The fix is Phase 5a's `forWhom` precedent, not a template language: the
// ternary stays in `utils/shardEngagement.js` and its RESULT arrives here as a
// declared optional. Two shapes, and each `example` shows which it is —
//
//   • a LABEL always has a value, so it can carry a sentence's spine;
//   • a TRAILING FRAGMENT may be empty and leads with its OWN SPACE, so the
//     sentence closes cleanly without it (`{{slainBy}}.` → "has fallen.").
//
// They are `required: false` and therefore additive: adding one is not a
// version bump (§4.3 — that is what `required: false` is for), and a rule or a
// template written before them keeps working unchanged.

// ── Owned asset at risk — the flagship family ──────────────────────────────
//
// All three resolve through the frame's `ownerAcct` → `shard_account_links` →
// a website user, which is what `ownerUserId` on the envelope carries. A house
// or vendor whose owner never linked an account is nobody to notify, and the
// mapper drops it rather than treating it as an error.
