feat(server): port the UO models, utils and schema fragment

Browse Source 
The data half of the extraction: 8 model directories, 13 utils, the shard
stream catalog and the 27-table schema fragment with its purge.

server/core.js is what makes the port a one-line import change per file rather
than a signature change per function. Ported code requires its dependencies at
file scope -- `const { query } = require('../../core')` -- which runs before
register() has been called and before any ctx exists. So every member is a
stable function that resolves ctx when CALLED, and nothing may be destructured
off ctx at init either, because core is free to hand over a getter.

Two helpers are vendored rather than taken from ctx, and the line between them
is the point. utils/excerpt.js is core's deriveExcerpt -- nine lines of pure
text handling. Core's sanitiser next to it was NOT copied: a second copy of a
security control diverges silently the moment either is fixed. announceLinks.js
vendors legError and articleUrl the same way, but baseUrl could not be: core's
reads APP_BASE_URL, and §2.7 forbids a module reading core's environment, so it
comes off ctx.site.baseUrl.

The schema fragment is core's 27 shard_*/uo_link_* statements, verbs CREATE,
ALTER and UPDATE only, every CREATE TABLE guarded. Two of its tables carry a
foreign key INTO users, which is allowed and is why the replay order matters --
core's schema is in place before this runs. The reverse never occurs and must
not: it would make core unable to boot without a module installed.

One real port bug caught by the integration run, not by tests: the atlas art
map resolved `../../../db/data`, which pointed at core's tree when this file
lived there and points outside server/ now. A path that happens to resolve is
exactly what survives a green suite, because the absent-file branch returns {}
and looks like the normal case.

// ── Shard-derived push streams + event → stream mapping ────────────────────
//
// MODULE-UO CONTENT, still living in core. MODULE_SYSTEM.md §1.8 named
// config/notificationStreams.js as one of the three genuinely entangled files:
// most of its catalog and all of `mapShardEvent` are shard-derived, and it reads
// `PUBLIC_KINDS` out of utils/shardBroadcast. PR 4 split it — core's one stream
// is config/coreStreams.js, and everything shard-shaped is here, in a file that
// moves to module-uo whole in Phase 3. Nothing in core imports it except
// modules/registries.js's registerCore(), which is the one line Phase 3 deletes.
//
// Two families:
// • public / opt-in — no linked game account required; delivered to every
// subscriber. Drawn ONLY from the SSE public allowlist
// (utils/shardBroadcast PUBLIC_KINDS) — a sensitive kind
// can never produce a public push.
// • personal / owner-keyed — require a linked game account; delivered ONLY to
// the owning user's devices (resolved from the event's
// game account via shardLinks), never fanned out publicly.
//
// The payload the relay ever carries is a CONTENT-FREE tickle ({ stream, ref });
// `ref` is an opaque hint (serial / city / timestamp) the app uses to pull the
// real, ownership-checked content over the authenticated API. So even a leaked
// ntfy topic reveals nothing (docs/android/PLAN.md §11).

-- ── module-uo's schema fragment ───────────────────────────────────────────
--
-- Replayed by core on EVERY boot, after core's own schema.sql and before
-- seedDefaults (MODULE_API.md §2.6). Everything here is therefore idempotent:
-- every CREATE TABLE carries IF NOT EXISTS and every ALTER carries
-- IF NOT EXISTS, because a statement that succeeds once and fails afterwards
-- presents as a module that worked until the first restart.
--
-- Core validates this file at LOAD time, before anything mounts — statement by
-- statement, split by the same code that splits core's schema. The rules it
-- enforces and the reason each exists:
--
-- • Leading verbs are an allowlist: CREATE, ALTER, INSERT, UPDATE. Not a
-- DROP denylist — this file replays every boot, so TRUNCATE or DELETE would
-- empty a table on each restart.
-- • Every table is prefixed. `shard_*` and `uo_link_*` are grandfathered to
-- this module by name (loader.js LEGACY_TABLE_PREFIXES): they predate the
-- module system by two years, they hold live data, and renaming them would
-- be a migration this workstream deliberately does not do. Every module
-- written after this one prefixes with its own id.
-- • No table core declares may appear here, and no table another module has
-- claimed.
--
-- Two tables carry a foreign key INTO core (`users`), which is allowed and is
-- why the replay order matters: core's schema is already in place when this
-- runs, so `users` exists. The reverse — a core table referencing one of these
-- — does not occur and must not: it would make core's schema depend on a module
-- being installed.
--
-- Teardown is `purge.sql`, which is never run by a boot. See it for the drop
-- order, which is the reverse of the dependency order here.

// The cliloc table — UO's id → display-string map, refreshed from a file the
// operator converts once from their own client.
//
// Why the site holds this at all: items on the wire carry a `LabelNumber`, not a
// name. `char.profile.equipment` has always sent `cliloc`, and every marketplace
// listing sends one too. Without the table the UI can only print `id 1023721`
// where the game prints "quarter staff".
//
// Two rules govern the boot path, both inherited from the spawn atlas:
//
// 1. **It never blocks startup.** No configured path, an unreadable file, a
// wrong-format file, a database error — all caught and logged. The site
// comes up either way, serving whatever table it already had (or none, in
// which case the UI falls back to item ids exactly as it did before).
// 2. **Nothing client-derived is committed.** The table is built from the
// operator's own file at a configured path. The repo ships no strings.
//
// The table is built from a SET of sources — the converted client table plus
// every operator-maintained overlay beside it — because shards edit items and
// add new ones, and those carry cliloc ids no stock client table has. All of
// them are re-read on every boot and hash-gated together, so adding one custom
// item never means re-exporting a 5 MB client file. Later sources win.
//
// That set is also why this has the atlas's escalation, in a lighter form. A
// single corrupt file fails the parse loudly, but a source that has simply
// VANISHED parses perfectly and imports a table quietly missing everything it
// contributed — the same ambiguity (real change vs half-copied mount) the atlas
// stages a facet removal for. So a disappearing source is refused and reported
// rather than applied.
//
// It is lighter than the atlas's because it needs to be: the atlas stores a
// pending decision in its own table and adds approve/reject endpoints, whereas
// here the decision is a single boolean an admin passes to the import they were
// already going to run. Re-parsing at approval time — the property that makes
// the atlas store only the decision — is automatic when there is nothing stored.

// Cliloc parsing — the pure half.
//
// A "cliloc" is UO's localization table: an integer id mapped to a display
// string. Items carry a `LabelNumber` rather than a name, so without this table
// the site can only render `id 1023721` where the game shows "quarter staff".
// The shard already sends the id on every equipment entry (`char.profile`'s
// `cliloc` field) and will send one per marketplace listing — the *number* was
// never the missing piece, the *table* was.
//
// This module is fs-free on purpose, exactly like `spawnAtlasParse.js`: the
// suite runs in CI where there is no UO client, so every parser here is driven
// from inline fixtures. `clilocSource.js` is the only thing that touches disk.
//
// ── Two input formats, and why ─────────────────────────────────────────────
//
// The client's own `Cliloc.enu` is COMPRESSED (Mythic format) on any modern
// client, and decompressing it is a bit-level port of an inverse-BWT coder that
// nothing in this stack needs at runtime. ServUO's own bundled `Ultima.StringList`
// cannot read it either — which is why `VendorSearch.GetItemName` is already inert
// on such a shard and the plugin could not supply names even if we asked it to.
//
// So the operator converts once, from their own client, and points the site at
// the result (see docs/website/CLILOCS.md). Two shapes are accepted because
// different tools produce different things:
//
// • PLAIN BINARY — the pre-compression cliloc layout: a 6-byte header, then
// records of {int32 number, byte flag, uint16 length, UTF-8 bytes}.
// • DELIMITED TEXT — `number<TAB|,|;>text` per line, which is what the common
// GUI exports emit. Quoted CSV fields and a header row are tolerated.
//
// Nothing derived from the client is ever committed: the converted file lives at
// an operator-supplied path and is gitignored, the same rule the spawn atlas art
// map already follows.

// Cliloc table — the filesystem layer.
//
// `clilocParse.js` holds the pure parsers; this module is the only thing that
// touches cliloc files on disk, and it is shared by both callers:
//
// - the server, which refreshes the table on boot (`shardClilocs.model.js`)
// - the admin panel, which can force a reimport without a restart
//
// The files are the OPERATOR'S (see docs/website/CLILOCS.md). Nothing derived
// from them is committed: the repo holds no string table, exactly as it holds no
// map snapshot and no artwork. That rule is why this module reads a configured
// path instead of a path inside the repo.
//
// ── Why this reads a SET of files, not one ────────────────────────────────
//
// Shards edit items and add new ones. Those carry cliloc ids that a stock client
// table does not have — and forcing a 5 MB client re-export every time an
// operator adds one item would be miserable enough that the table would simply
// go stale, which is the exact failure the spawn atlas was redesigned to avoid.
//
// So this mirrors `spawnAtlasSource.readSources()`: a BASE table (the converted
// client file) plus every operator-maintained OVERLAY beside it, all re-read on
// every boot and hash-gated as a SET. Adding, editing or removing any overlay
// counts as drift and re-imports. Later sources win, so an overlay both adds new
// ids and overrides stock ones.
//
// Measured on a real shard: the script tree references 16,434 cliloc ids and only
// 37 are absent from the stock client table. Tens of entries against a 67k base
// is what makes the overlay the right shape rather than a second full table.
//
// Reading and hashing ~5 MB costs a few milliseconds and a full parse ~50 ms, so
// the boot path hashes first and only parses when something actually changed.

// Spawn atlas parsers — pure functions over strings, no `fs`, no dependencies.
//
// These back the CLI build script (`scripts/buildSpawnAtlas.js`), which is the
// only thing that reads a ServUO tree. Keeping every parser pure and fs-free is
// what lets the test suite cover them in CI, where no ServUO tree exists: the
// tests hand these functions literal XML strings.
//
// Four source shapes, two very different parsing strategies:
//
// Spawns/*.xml ~10.5 MB across 13 files, FLAT <Points> records
// → streaming regex, never a DOM. See parsePoints().
// Data/Regions.xml 129 KB, genuinely nested <region> inside <region>
// Data/Locations/*.xml nested <parent>/<child>
// Config/ChampionSpawns.xml 4.8 KB, <spawn>/<location>
// → the small recursive tokenizer below.

// deliberately a *subset* parser: it handles the constructs these four files

// or rename them when its maps are updated, so nothing here may name Felucca,
// Trammel or any other stock facet. The facet set is whatever the shard's own
// files say it is, discovered at parse time.
//
// The complication is that the sources disagree about spelling for the SAME
// facet and nothing in the files reconciles them: `Spawns/*.xml` `<Map>` and
// `Regions.xml` `<Facet name>` say `TerMur`, while `Data/Locations/*.xml` spells
// it `Ter Mur` and calls Tokuno `Tokuno Islands`. Left unreconciled this fails
// silently — the landmark bucket is keyed differently from the points looking it
// up, so the fallback never fires and every unregioned spawn on those facets
// reads "Wilderness".
//
// Reconciliation is therefore done by MATCHING, not by a lookup table:
// `facetKey()` collapses spelling differences, and `resolveFacetName()` matches
// a loosely-spelled name against the canonical set discovered from the shard's
// own data. A facet nobody else mentions keeps its own name rather than being

// paged and this walks it. Two bounds, both deliberate:
//
// • MARKET_SNAPSHOT_MAX caps the walk. A pathological world (or a sidecar whose
// store was never pruned) must not be able to hang startup — backfill runs
// before the site is serving the live feed, so an unbounded loop here is
// downtime, not slowness.
// • The loop stops on a SHORT page as well as on `total`, because a concurrent
// sweep can shrink the index underneath the walk and paging to a stale total
// would spin.
//
// Vendors are upserted, never reconciled-by-replacement. A vendor absent from the
// snapshot is absent because the sidecar dropped it on vendor.listing.remove —
// which our own ingest already processed — so clearing the table first would only
// create a window where the market page is empty.
