-# ── Package guard ────────────────────────────────────────────────────────────
-# This repo is in the planning phase and has no module code yet: the API contract
-# is settled in Phase 1 and Phase 3 is what extracts the UO half of `website/`
-# into this repo (docs/website/MODULE_SYSTEM.md §2.7). Rather than leave the repo
-# ungated until then — or land a workflow that red-Xes every governance/docs PR —
-# each half's gates are conditional on its package.json existing. Before the code
-# lands, the job reports green with a notice saying so. The moment a package.json
-# appears the gates arm themselves; nothing here has to change.
+# ── What each job is really asking ───────────────────────────────────────────
 #
-# The same trick guards the client build, which is the higher-risk half: it must
-# build with Vite in library mode with react/react-dom/react-router-dom EXTERNAL,
-# because there is exactly one React instance in the page and core owns it. A
-# module that bundles its own React loads and then breaks hooks at runtime, which
-# is precisely the kind of failure worth catching before merge.
+# The tests are the ordinary half. The two `check:*` scripts are the interesting
+# one, because they are the acceptance criteria of the module contract itself
+# (docs/website/MODULE_API.md Part 5) rather than of this module's behaviour:
 #
-# Not here yet, deliberately, because there is nothing for them to act on until
-# Phase 3: a release workflow (the `module-uo-<version>.tar.gz` artifact and its
-# sha256 manifest), the zero-internal-imports check, and the module's own frozen
-# route manifest. Each lands with the code it checks.
+#   • `server: check:imports` — no relative path escapes the module root, and no
+#     shipped file resolves a bare specifier. A module that reaches into core's
+#     tree works right up until core moves a file, and the whole boundary is
+#     worth exactly as much as this check is (§5.1).
+#
+#   • `server: check:bundle` — the release ships everything the entry point can
+#     reach. Every other job here runs against the whole repo, but a release is a
+#     SUBSET of it (release.yml assembles from the include list in
+#     `ci/bundle.json`), and nothing compared the two. On 2026-08-19 they
+#     disagreed: `server/commands/` arrived with the Teams cutover, the include
+#     list did not learn about it, and v1.0.0 installed and then died at the
+#     register stage on the operator's box with "Cannot find module
+#     './commands/guild.command'". Green here, broken there — because the subset
+#     only exists in the release. This asks, on the PR that adds the directory,
+#     whether the list still covers what index.js reaches.
+#
+#   • `client: check:externals` — the BUILT chunk has no bare imports left. That
+#     failure is invisible in source: `import { useState } from 'react'` is
+#     correct in every file, and whether it becomes core's React or a bare
+#     specifier no browser can resolve is decided by vite.config.js. It has to
+#     be asked of the artifact, so it runs after the build. (The other half —
+#     a shared dependency being BUNDLED — fails the build itself, from a
+#     resolution-time guard inside vite.config.js.)
+#
+# Building the chunk in CI is not only a check: it is how the chunk that ships is
+# produced, since an operator never builds (MODULE_SYSTEM.md §1.14).
+#
+#   • `server: check:swagger` — `swagger-fragment.json` describes the routes this
+#     module registers, today. Core has no way to generate it: core is a prebuilt
+#     image, this module arrived on a volume afterwards, and it mounts through a
+#     call no static parser can follow. So the fragment core merges into
+#     `/api/docs.json` is whatever this repo committed, and a stale one documents
+#     a URL surface that does not exist (§2.8).
+#
+#   • `frozen-manifest` — the job with the interesting shape. It clones CORE at
+#     the ref pinned in `ci/core-ref.json`, generates its route manifest twice
+#     (without this module, then with) and takes the difference. That difference
+#     is what this module serves, and it is checked three ways: it must match the
+#     committed `routes.manifest.json`, it must not have REMOVED or changed one of
+#     core's own routes, and every route in it must have an operation in
+#     `swagger-fragment.json` — the per-module form of core's rule that a route
+#     which isn't in the spec doesn't ship (§5.3, §2.8).
+#
+#     Nothing else can ask those questions. Every other check here runs against
+#     this repo alone, where a mount prefix is a string in `server/index.js` and a
+#     documented path is a string in a JSON file; whether they name the same URL
+#     is a fact about a running core, and this is the only job that has one.
+#
+# Still not here, deliberately: nothing. The release workflow is
+# `.gitea/workflows/release.yml` and runs on a tag rather than on a PR.

+# Build and publish the installable bundle: `module-uo-<version>.tar.gz` plus the

+#
+# ── What a release IS here ──────────────────────────────────────────────────
+#
+# **An operator never builds anything** (MODULE_SYSTEM.md §1.14 — the constraint
+# the whole module system is shaped around). So a release is not source: it is the
+# directory core's loader expects to find at `modules/uo/`, already assembled —
+# the prebuilt client chunk, the one runtime dependency installed, the schema
+# fragment and the OpenAPI fragment — packed as it will be unpacked. Phase 4's
+# admin install downloads the tarball, verifies it against the `sha256` in the
+# manifest, and unpacks it onto the volume. Nothing runs `npm` on the way.
+#
+# ── The version is DERIVED, and the declaration is a floor ──────────────────
+#
+# This file used to release only when a merge to `main` left `module.json` at a
+# version with no release yet — the version DECLARED, never computed, on the
+# argument that two sources for one number is how they drift. That was true and
+# it was still the wrong trade: it makes every bundle cost a second reviewed PR
+# whose entire content is a number, and between 2026-08-12 and 2026-08-19 it cost
+# this repo *every* bundle — v0.3.0 was the only release while nine phases of
+# Teams work landed, because nothing in them touched that line.
+#
+# So the engine `link` and `installer` already run is adopted here (MODULE_SYSTEM
+# §2.7.1, decision 19 as amended):
+#
+#   feat!: / BREAKING CHANGE  -> major     feat: -> minor     fix|perf: -> patch
+#   nothing releasable        -> no release is cut
+#   (first ever run, no tag)  -> releases what module.json declares
+#
+# **The declared version is kept as a floor, not deleted.** If `module.json` names
+# a version above the newest tag, that version releases — which is the old model
+# exactly, surviving as the special case it always was. Raising it by hand is
+# still how you say "this one is a minor, whatever the subjects imply", and it is
+# still the natural place to move when a `coreApi` bump forces the question. What
+# no longer happens is a merge full of `feat:` producing nothing.
+#
+# The number that ships is therefore the TAG, and CI writes it into the
+# `module.json` inside the bundle at assembly time. The committed `module.json` is
+# a floor and a starting point, not a record of the last release — `link` reached
+# the same arrangement with `Cargo.toml`, for the same reason: a release engine
+# that has to commit a bump back to `main` stops working the day someone protects
+# the branch, and this one is protected.
+#
+# ── The backdoor ────────────────────────────────────────────────────────────
+#
+# `workflow_dispatch` publishes on demand, for the case the rules above cannot
+# reach: `module.json` changed in a way worth shipping — a widened `coreApi`, a
+# new mount, a capability — with no releasable code behind it. Leave `version`
+# blank to bump the newest tag by `bump` (default `patch`), or name an exact
+# version to publish that. A dispatch releases even when nothing in the log is
+# releasable; that is the entire point of pressing the button.
+#
+# Re-running on a version that is already released is a no-op, so a rerun after an
+# unrelated failure is safe. A tag that exists with no release behind it is NOT a
+# no-op — see the recovery branch in the plan step.
+#
+# This workflow still never writes to a branch. It tags and publishes, so `main`
+# needs no push exception.

-Nothing lands here until Phase 1 has settled the contract this module is written against. Phase 3 is
-what fills the repo.
+Phase 3 moved the UO half of `website/` here in six slices (`MODULE_SYSTEM.md` §2.7.1): the bundle
+skeleton, the whole server half, core's client extension slots, the whole client half, the de-UO of
+core's own copy, and this one — the artifacts that make the result installable and checkable. Each
+slice was one PR here that added and one in `website` that deleted, this one merging first, so
+`website`'s `edge` branch served each feature from core right up to the moment core dropped it.
 
-## What it will contain
+Neither half sliced by feature in the end, and for the same reason on both sides: a mount prefix is
+claimed whole and a shared leaf moves with its **last** consumer, so the closure of either half is
+the whole half.
+
+**What core serves and what this repo serves is now a fact you can read**, not a claim: 72 URLs, in
+[`routes.manifest.json`](routes.manifest.json), derived by loading this module into a real core and
+diffing. Not one of core's own URLs moved — that is the promise `MODULE_SYSTEM.md` §1.2 makes to the
+shipped Android app and the Discord bot, and it is checked on every PR.
+
+## Working on it
+
+```bash
+npm ci --prefix server  && npm test --prefix server  && npm run check:imports --prefix server
+npm run check:swagger --prefix server          # is swagger-fragment.json still current?
+npm ci --prefix client  && npm test --prefix client  && npm run build --prefix client
+npm run check:externals --prefix client        # asks the BUILT chunk, so it runs after the build
+```
+
+The `check:*` scripts are the contract's acceptance criteria rather than this module's own tests: no
+import may escape the module root (`MODULE_API.md` §5.1), no bare specifier may survive into the
+built chunk (§3.6), and the OpenAPI fragment core merges must describe the routes registered today
+(§2.8). The matching build failure — a shared dependency being *bundled* — comes from a guard inside
+`vite.config.js`.
+
+**Changed a route, or its `#swagger` annotations?** `npm run swagger --prefix server` regenerates
+`swagger-fragment.json`; commit it. Core cannot generate it — core is a prebuilt image and this
+module mounts through a call no static parser can follow — so the file this repo commits is the one
+an operator's `/api/docs` shows.
+
+**Changed a mount prefix, or added a route?** `routes.manifest.json` is regenerated by the
+`frozen-manifest` CI job, which clones core at the ref pinned in [`ci/core-ref.json`](ci/core-ref.json),
+loads this module into it and takes the difference. To do it locally, check this repo out into that
+core as `modules/uo` (**copy it — a symlink is silently skipped by the loader**), run core's
+`npm run routes:manifest` with and without it, and hand both files to
+`server/scripts/frozenManifest.js`.
+
+Running it against a real core means checking this repo out as `website/modules/uo`, building the
+client half, and booting core. The four-step browser smoke in `MODULE_API.md` §7.7 is the only thing
+that proves the client half works: its real failure modes are timing and module resolution, and
+neither has a shape a DOM-less test runner can see.
+
+## What it contains
 
 One repo, one bundle: the server half and the client half live side by side and version together, so
 a route and the screen that calls it can never be mismatched.

 It deploys the *shard* side — the plugin overlay and the uo-link sidecar — and never contacts the

+### Releases
+
+**Every merge to `main` that carries a releasable commit publishes a bundle.** The next version is
+computed from conventional-commit subjects since the newest `v*` tag, as in `link` and `installer`:
+`feat!:` or `BREAKING CHANGE` is a major, `feat:` a minor, `fix:` or `perf:` a patch, and a `main`
+that gained none of those cuts no release. The number that ships is the **tag**, and CI writes it
+into the `module.json` inside the bundle.
+
+`module.json`'s version survives as a **floor**: name a version there above the newest tag and that
+version is what releases, which is how you overrule the subjects — when a `coreApi` bump forces a
+minor, say. What no longer happens is a `main` full of `feat:` producing nothing because a separate
+PR to move one number had not been merged yet.
+
+For a change with nothing releasable behind it — a widened `coreApi`, a new mount, a capability —
+run the **Release** workflow by hand (Actions → Release → Run workflow). Leave `version` blank to
+bump the newest tag by `bump` (default `patch`), or type an exact version to publish that.
+
+Each release carries:
+
+| Asset | What it is |
+|---|---|
+| `module-uo-<version>.tar.gz` | the directory core expects at `modules/uo/` — already assembled, with the chunk built and `ws` installed |
+| `module-uo-<version>.json` | id, version, `coreApi`, the artifact's URL, size and **`sha256`** |
+| `SHA256SUMS` | the same hash, in the shape every other repo here publishes |
+
+Releases are **unsigned**; the `sha256` is the trust anchor, and the website verifies it before
+unpacking. That is the model `installer`'s bundles already use, and a second trust model would be a
+second thing to get right.
+
+The tarball is assembled from an **include** list, never an exclude list — an exclude list ships
+whatever it forgot. Tests, scripts, `client/src` and the dev dependencies are not in it.
+
+## Environment variables
+
+Four, all optional, all read by this module rather than by core — which is why they are documented
+here and not in core's `.env.example`. In Docker they go in the Compose `.env`, since that is what
+reaches the container.
+
+| Var | Default | What |
+|---|---|---|
+| `UOLINK_BASE_URL` | — | Default sidecar base URL for a site with nothing saved yet. The admin panel's stored value wins. |
+| `UOLINK_WS_URL` | — | Same, for the WebSocket URL. |
+| `UOLINK_PROTOCOL` | `8` | Wire protocol this build speaks. Again only a fallback — set it lower only if you deliberately run an older sidecar. |
+| `TOWNCRIER_DURATION_SEC` | `3600` | How long a published news post's in-game town-crier message stays up (≤ `86400`). |
+
+**The sidecar's auth token is deliberately not here.** It is entered in Admin → Shard, encrypted at
+rest with core's `SECRET_ENC_KEY`, and write-only in the API — never returned to any client.

+// ── §5.1's client half — what stayed a bare import in the built chunk ──────
+//
+// The server half's boundary check reads source. The client half's has to read
+// the BUILD OUTPUT, because the failure it exists to catch is invisible in
+// source: `import { useState } from 'react'` is correct in every file, and
+// whether it ends up as core's React or as a second copy welded into the chunk
+// is decided by vite.config.js's aliases. A missed alias changes nothing you can
+// see until a hook throws in the browser.
+//
+// So: build, then ask the artifact two questions.
+//
+//   1. **Is there a bare import left?** There must not be. Aliased shims are
+//      bundled, so a surviving bare specifier means an alias missed and
+//      `external` caught it — the loud failure the config prefers, but still a
+//      failure, and better found here than by a browser refusing to load.
+//   2. **Did a shared dependency get bundled?** React's own source has
+//      fingerprints that no module of ours would contain by accident. Finding
+//      one means the chunk carries a second React, which is the silent version
+//      of the same mistake and the one worth the fingerprint check.
+//

+// would capture `undefined` at file scope. There is no such gap here.
+// `window.__rg` is published by core's own bundle (client/src/modules/shared.js),
+// and every module chunk is a deferred script the server injects *after* that
+// bundle's tag, so by the time the first line of this file executes the global
+// is already there. Reading it once, at module scope, is safe — and it means a
+// ported component keeps the ordinary `import { PageHeader } from '…'` shape
+// rather than being wrapped in an accessor that would cost it its identity.

+// tree and would otherwise re-prompt on every restart forever; an asset import
+// only ever happens because somebody pressed a button on this page, so the
+// review is in front of the person who caused it, by construction. Declining is
+// therefore not a decision to remember — it is simply not pressing the other
+// button.
+//
+// The pictures matter. `body/820/a23` names nothing a human recognises; the horse
+// it is a picture of does, and "is it right that these disappear?" is not a
+// question anyone can answer from a list of keys.

+// Core registers it through the same seam a module uses

+// already uses for the feature seam. The mechanism is therefore exercised by
+// core's own content from the day it lands, rather than first proved by the
+// change that depends on it.
+//
+// The slot hands over `userId` and nothing else — deliberately, not `scope`.
+// `api.admin.userShard` is a UO binding that leaves core in slice 3, so a slot
+// that passed it would be handing a module something core is about to delete.
+// An extension builds its own client for the routes it registered at the other

+// module is what populates them — but core does not own the word "guild", so it

+// on it is core's, because only core can resolve whether the viewer is inside the
+// Team, and the public/members split on that feed is a security boundary.
+//
+// So the module declares `uo.guild.detail` (entry.jsx) and core fills it. On a
+// core that does not know about Teams the slot is simply never filled and this
+// page renders its roster alone, which is the same tolerance every other slot has.
+//
+// The roster comes from this module's OWN board — the same data it answers core's
+// Team provider from — rather than from core's Team API. That is deliberate: the

+// timing and resolution, and a DOM-less runner cannot see either. That is still
+// true, and MODULE_API.md §7.7's browser smoke is still what proves the module

+// It can be checked, because registration is the one thing this chunk does at
+// evaluation time and it does it through an object core hands it. So: stand up a
+// fake `window.__rg` with a recording registry and the real React behind it,
+// import the BUILT artifact, and read back what it asked for. No DOM is needed
+// because nothing renders — `<Shard />` is `jsx(Shard)`, an object, and the
+// route table is full of them by design.
+//
+// What this catches that review does not: a page that silently stops being
+// routed, a nav row whose `to` drifts from its route's path, a slot fill that
+// was renamed on one side, and the whole registration surface disappearing
+// because an exception was thrown halfway down entry.jsx.
+//
+// What it deliberately does NOT do is re-assert the paths as a literal list.

+// **2. The aliases replace `external`; they do not accompany it.** §3.6 shows
+// both, and they do not compose: Rollup asks `external` BEFORE Vite's alias
+// resolver runs, so a specifier listed there is marked external and never
+// aliased. The chunk then ships bare `import 'react'` specifiers, which the

+// forbids the inline script an import map has to be. (`output.globals` would

+//
+// **3. What `external` was there to guard is guarded by `assertSharedNotBundled`

+// that guarantee if the listener is still closed.
+//
+// **One behavioural change, and it is deliberate.** In core, `uoLinkSocket.start()`

+// with its own catch. Reporting whether the bridge is up is diagnostics; being up

+// gracefully when the shard is down.

+// ── 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.

+-- ── module-uo's teardown ──────────────────────────────────────────────────
+--
+-- Destructive, and run ONLY by an explicit admin purge (MODULE_API.md §2.6).
+-- Nothing on the boot path ever executes this file — uninstalling a module
+-- leaves its data alone, and removing the data is a separate decision an
+-- operator has to make on purpose.
+--
+-- It exists because `schema.sql` does. A module that can create tables and
+-- cannot drop them leaves an operator with orphaned data and no supported way
+-- to remove it, which is why core refuses to load a module that declares one
+-- without the other.
+--
+-- **The order is the reverse of creation, and that is load-bearing**: two of
+-- these tables carry a foreign key into core's `users`, and several reference
+-- each other. Dropping a parent before its children fails on the constraint,
+-- and a purge that fails halfway is worse than one that does not run — it
+-- leaves exactly the orphaned data this file exists to remove. `IF EXISTS` on
+-- every line so a partially-installed module still tears down cleanly.
+--
+-- What is NOT here, deliberately: rows this module wrote into core's tables.
+-- `notification_subs` rows for `shard.*` streams and `announce_job_legs` rows
+-- with leg `towncrier` belong to core's tables, and a module does not delete
+-- from those — core prunes them when it drops the registrations, which it can
+-- do because it knows which registrant owned what. The two `settings` rows
+-- schema.sql seeds (`game_account_signup`, `uo_link_protocol_3_migrated`) are
+-- the same case with an extra reason: the second is a one-shot MIGRATION
+-- marker, and deleting it would re-arm a protocol bump against tables this
+-- file has just dropped.
+
+-- The Asset Bridge's three (phase 3). No foreign keys of their own, so they lead:
+-- `shard_creature_bodies.slug` mirrors an atlas slug and `shard_assets.body` a body
+-- id, but neither is declared as a constraint — the atlas tables are rebuilt from
+-- scratch on every refresh, and an FK into a table that is emptied and refilled
+-- would make an ordinary re-parse fail on rows that are about to be re-inserted.
+--
+-- The uploaded PNGs are NOT removed here. They live under the uploads directory
+-- alongside the operator's own artwork, this file drops tables rather than files,
+-- and a purge that deleted an operator's hand-drawn creature portraits because
+-- they shared a directory with imported ones would be unrecoverable.

+--
+-- 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.

+--
+--    `owner_acct` is the one that matters structurally: the table has carried
+--    `owner_name` since Protocol 3, but a character name is not an identity — only
+--    the game ACCOUNT joins to shard_account_links, so until now a vendor row named
+--    an owner the site could not resolve to a user.
+--
+--    The fee columns describe PlayerVendor.PayTimer's dismissal rule: at each tick
+--    the charge is compared with the funds and the vendor is destroyed when the
+--    charge wins. `dismissal_at` is that comparison resolved into an instant, which
+--    is what any surface actually wants; the parts are kept alongside it so a
+--    display can explain the number rather than only state it.
+--
+--    `fees_exempt` marks a commission vendor: it has no pay timer at all and is
+--    never dismissed for fees, which is a different thing from having a long time
+--    left and must not render as one.

+--    missed an earlier migration is carried the whole way; the one-shot marker is
+--    written here in the module's own fragment, because core's schema is replayed in
+--    full BEFORE any module fragment and a marker left in core would already exist
+--    when this UPDATE read it.

+
+-- 4. The protocol pin again, at 7 -- and this block is a FIX to already-merged
+--    code rather than ordinary Phase 12b work.
+--
+--    Phase 11a took the wire to 6 and Phase 12a took it to 7, and neither moved
+--    this. `uoLinkClient` sends `X-UOLink-Version: <this column>` on every call and
+--    the sidecar answers an exact mismatch with a 409, so a deployment that installed
+--    this module at any point since Phase 10 would have had EVERY sidecar call
+--    refused against a protocol-7 sidecar -- the whole event plane dead, loudly but
+--    for a reason nobody would look here for.
+--
+--    It survived two phases because both live walks set the column by hand while
+--    standing the rig up, which is exactly the shape of a migration nobody runs.
+--    One block carries an install the whole way rather than one per missed version:
+--    `protocol < 7` is deliberate, and it is why the 4 and 5 blocks above wrote
+--    `< n` rather than `= n-1`.

+
+-- The protocol pin at 8 -- the Asset Bridge (docs/link/v8.md), and the first bump this
+-- module takes IN the phase that consumes it rather than a phase or two later.
+--
+-- Phase 1 of that work moved `link`'s PROTOCOL_VERSION and the overlay's `overlay.toml`
+-- together, because the installer refuses to pair a sidecar and an overlay that disagree.
+-- Nothing enforces the third declaration -- this one -- and the block above is the record
+-- of what that costs: two phases of every REST call answered `409 protocol version
+-- mismatch`, invisible because both live walks had set the column by hand.
+--
+-- Phase 2 is where this module first calls a protocol-8 route (`GET /cliloc`), so it is
+-- where the pin moves. Same one-shot shape and the same `protocol < 8`, so an install
+-- that missed an earlier bump is carried the whole way rather than one step.

+
+-- `shard_spawn_points.unique_id` for an install that already had the table
+-- (Asset Bridge phase 9; the column itself is Events phase 12b).
+--
+-- The column was added to the CREATE TABLE above and nowhere else, so it reached
+-- fresh installs and no existing one -- `CREATE TABLE IF NOT EXISTS` does not add
+-- a column to a table that is already there, which is what every ALTER in this
+-- file exists to do. `replaceAtlas` inserts `unique_id` unconditionally, so on an
+-- upgraded install EVERY spawn-atlas import since v1.2.0 has failed outright with
+-- `Unknown column 'unique_id' in 'INSERT INTO'` -- the bestiary, the spawn map and
+-- the champion altars all frozen at whatever was last imported.
+--
+-- Found by the phase 9 acceptance walk, on a rig whose tables predate 12b: a fresh
+-- install cannot reproduce it, and neither can a test whose schema is this file
+-- applied to an empty database. That is the same blind spot the protocol-pin block

+// Core requires this file once, synchronously, while `app.js` is still being

+// contract is docs/website/MODULE_API.md §2.2; the three rules that shape every
+// line below are worth restating where they will be read:
+//
+//   1. **No `await`, and no database.** `scripts/routeManifest.js` and
+//      `swagger/swagger.js` both require core's `app.js` with the pool pointed
+//      at a dead port, so a module that queried at registration time would hang
+//      both. Everything needing a live database is in `onBoot`.
+//   2. **Never resolve what core owns.** This module lives at
+//      `<website>/modules/uo/`, outside `server/`, so Node's resolver never
+//      reaches core's `node_modules` and `require('express')` fails outright.
+//      express, express-validator, the database, the logger, the middleware and
+//      the rest of §2.3 arrive on `ctx` and are re-exported by `./core`.
+//   3. **Never reach into core's tree.** No relative path may escape this
+//      module's root; `scripts/checkImports.js` enforces that in CI (§5.1).
+//
+// **Require order is load-bearing, and it is why the requires below are inside
+// the function.** Every ported file reaches core through `./core`, whose members
+// resolve `ctx` when called — but a router does `const express = core.express` at
+// its own file scope, which runs the moment it is required. So `core.init(ctx)`
+// has to happen before the first `require` of anything under `router/`. Hoisting
+// these to the top of the file would break the module with an error about `ctx`

+// Client artwork, over the bridge (docs/link/v8.md — protocol 8, phase 3).
+//
+// What this replaces: until now the only way a creature got a picture on this
+// site was for an operator to open UOFiddler on a desktop, export sprites by
+// hand, copy them to the web host and write a `spawnAtlas.art.json` naming each
+// one. Almost nobody did, so `shard_spawn_creatures.art` was NULL on every
+// install and the atlas rendered as text.
+//
+// The shard has had those files the whole time — a ServUO server cannot boot
+// without a UO client — so as of protocol 8 it decodes them itself and hands the
+// pictures over the same request/reply path as every other shard read.
+//
+// ── Two passes, and they answer different questions ───────────────────
+//
+// **The catalogue** (§4.8, §11) is one thumbnail per creature body: the shard
+// walks bodies 0–2047, validates each index entry, decodes the ones that are real
+// and hands back `{ key, sha256 }` first and the PNG second. On a stock client
+// that is **1,095 sprites** — 787 out of the legacy anim files, 235 more out of
+// the UOP packages (phase 4), and 73 more since phase 6, which have no art at
+// action 0 and real art at a later one. Never the 1,144 the decoder claims.
+//
+// A key therefore names its action — `body/820/a23` is a horse whose action 0 is
+// empty — and the key is still one per body. Nothing here treats `a0` as the
+// shape of a body key; the atlas join reads the row's own action (§11.2).
+//
+// **Body resolution** (§8) is the join. The atlas knows a creature by the class
+// name in `Spawns/*.xml`; the client knows it by a body id; nothing in the ServUO
+// tree declares the mapping. Only code inside ServUO can answer it, by
+// constructing the creature and reading `Body.BodyID`, and that is the whole
+// reason this could not be done off the shard.
+//
+// ── The 357, and why nothing here trusts a success ────────────────────
+//
+// 357 of the bodies ServUO's decoder returns a bitmap for **have no art**. Their
+// index entry reads `length 0`, the library's stream buffer still holds the
+// previous creature, and what comes back is whichever body was decoded before —
+// a real, plausible, correctly-sized picture of the wrong animal. The shard now
+// validates every index entry before it decodes, which is what cut the catalogue
+// from 1,144 to 787, and the count going down is the point.
+//
+// The consequence for this file is a rule: **a missing asset is a normal
+// outcome, never an error.** Two thirds of the player bodies have no art on a
+// stock client (§5.2), so an import that reported eight failures every time would
+// teach an operator to ignore the panel.
+//
+// ── Where the pictures go, and what still wins ────────────────────────
+//
+// Into `<uploads>/atlas/`, through the same door the operator's own artwork uses,
+// and `shard_spawn_creatures.art` is DERIVED from them rather than written by
+// them. **The operator's `spawnAtlas.art.json` still wins outright**: someone who
+// has drawn their own creature portraits must not have them replaced by a sprite
+// rip on the next Update.
+//
+// ── Why the resolution does not live on the atlas row ─────────────────
+//
+// `shard_spawn_creatures` is emptied and refilled on every atlas refresh. A body
+// id or a filename stored there would be destroyed by an ordinary re-parse of the
+// ServUO tree, and the next asset Update would find the client files unchanged,
+// report "nothing to do" and never restore it. So both live in their own tables
+// and the atlas import reads them on the way past.

+//
+// ── Why this is not the body catalogue with a different prefix ─────────
+//
+// The bestiary wants every creature, so phase 3 imports a SET: walk a manifest,
+// diff the hashes, fetch what moved. That works because the set is 1,095 rows
+// and one megabyte.
+//
+// This side has no set. The shard's client addresses 49,152 item graphics and
+// has art for 39,189 of them; multiply by three thousand hues and there is
+// nothing to enumerate, no manifest worth building and nothing worth importing
+// ahead of time. What there IS, at any moment, is a few hundred keys that the
+// site's own rows actually name: the items on a vendor, the things a character
+// is wearing. That is the working set, and it is what this fetches.
+//
+// ── Who is allowed to make the shard do work ──────────────────────────
+//
+// **Ingest warms; the route only serves** (org lead, 2026-09-11). A page never
+// waits on the shard and never causes a fetch: it renders the pictures already
+// on disk and leaves out the ones that are not, which is exactly the state every
+// install was in before this phase and which every surface already handles.
+// Fetching happens behind that, from the keys the site has stored.
+//
+// The alternative — fetch on the first request for a key — was rejected on one
+// number. The shard's asset plane serves **one request at a time** by design
+// (§3.2), so any anonymous visitor able to name a key could walk 49,152 ids
+// times 3,000 hues through that single slot and keep an operator's own import
+// waiting behind it, from a URL with nothing to authenticate. Warming from the
+// site's own data has no such surface: the ceiling is the number of distinct
+// (item, hue) pairs the shard itself has told us about.
+//
+// ── Why the wanted set is DERIVED and not a queue ─────────────────────
+//
+// A queue table would need writing on the ingest path, draining, retrying,
+// pruning and reconciling after a restart. The same answer falls out of a
+// `SELECT DISTINCT` over the rows that name the items — which is self-healing by
+// construction: a key lost to a restart comes back the next time the pass runs,
+// and a key for a vendor that has gone stops being wanted the moment its row is
+// deleted. The in-memory set below is an optimisation on top of that, never the
+// record: it exists so a picture seen on a LIVE character sheet — which is
+// fetched from the shard per request and stored nowhere — is not forgotten.
+//
+// ── Staleness, without a manifest (§7) ────────────────────────────────
+//
+// Every fetched row records the shard's `catalog` id, which is a hash of the
+// files that decide the bytes. A client patch changes it, a restart does not. So
+// "is this picture out of date?" is a per-row comparison rather than a manifest
+// diff, and the answer costs nothing for the pictures nobody is looking at any
+// more: they are simply never re-fetched.

+// 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 — a base 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. Later sources win,
+// so an overlay both adds ids the client never had and overrides stock ones.
+//
+// ── Where the base comes from (protocol 8, docs/link/v8.md §9) ─────────
+//
+// **The shard**, on any install with uo-link configured. It has the operator's
+// client files already — a ServUO server cannot boot without them — and since
+// phase 2 it has the decompressor too, so `GET /cliloc` returns the table and
+// nobody installs UOFiddler or copies a 5 MB file anywhere.
+//
+// **A file on disk** otherwise. That is the pipeline this replaces, kept for
+// installs with no shard link and for development, and deprecated rather than
+// removed: an operator who has one keeps working, and an operator who has a shard
+// never builds one. Passing an explicit `path` to `refresh()` still selects it,
+// which is the escape hatch for "import from this file, this once".
+//
+// **Overlays are always the filesystem's**, either way. There is nothing on the
+// shard to ask for: ServUO has no server-side notion of a custom cliloc, so the
+// `custom/` directory is the only place those ids exist.
+//
+// ── What that changed about WHEN this runs ───────────────────────
+//
+// Boot no longer imports on the shard path. The file path could hash 5 MB locally
+// on every restart and skip; the shard path would mean a sidecar round trip in the
+// boot sequence, for a table that changes when an operator patches their client —
+// an event they know about and we do not. So on the bridge, importing is an admin
+// action (Admin → Shard), and boot leaves whatever is loaded serving.
+//
+// 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.
