335d69d122 fix(modules): core offers a contribution, never a slot name

The inverted slot direction reached exactly one module. Core filled three
literal names - uo.guild.detail, uo.guild.forum, uo.guild.header - matched by
exact name in applyCoreFills, so a second game declaring a place under its own
id got an empty page and no error. "A fill for a slot nobody declared is not an
error" is the rule that made the miss invisible, and it is the right rule; what
was wrong was core knowing a slot's name at all.

It also put a module identifier inside core, in three string literals
scripts/checkModuleIdentifiers.js masks by construction and could never catch.

Found by the integration kit while writing the chapter that teaches this shape
to an audience outside this org - which is what that phase is for.

So the module says WHERE, in its own vocabulary, and WHICH of core's
contributions goes there:

  declareModuleSlot(ID, 'uo.guild.detail', { core: 'team.activity' })

and core offers into the catalogue rather than into a name:

  offerCoreFill('team.activity', TeamActivityFeed)

CORE_CONTRIBUTIONS is exported and fixed at build time, so asking for one core
does not offer THROWS at the declaration. That asymmetry with an unfilled slot
is deliberate: an unknown contribution is always a typo or a version skew - the
module's coreApi range has already been checked - and the failure it would
otherwise produce is a page that renders empty forever with nothing logged.

options.core is optional; a slot that asks for nothing stays empty, which is
what a module declaring a place it fills itself wants. More than one slot may
ask for the same contribution and each gets it: how many places a module wants
its feed in is a layout decision on a page core does not own.

Amends MODULE_API 1.6.0 in place rather than adding 1.7.0 - the same rule the
eighth and ninth members were given, and 1.6.0 has only ever been on edge.

Also: the UI kit is nine exports, not eight. Slot made it nine in phase 3 and
the comment beside it still said eighth.

288 client tests, 1162 server tests.

b458c1f46f feat(teams): the web surface — a notifications screen that did not exist
This is phase 6's first finding, and it changed the phase's shape.

TEAMS.md §6.3 says the per-Team mute list is surfaced "under the existing
notification settings screen". There was no such screen. `/auth/me/notifications/*`
was built for the Android app in M7 and had ZERO web consumers — a browser could
not see the stream catalog or its own subscriptions at all. That is tolerable
while push is the only sink, because push needs the app anyway. It is not
tolerable for email, whose entire argument is the web-only user who runs neither
the app nor Discord, so the sink and the screen to configure it had to ship
together.

`/account/notifications` carries all three: what to be told about, which Teams,
and whether any of it reaches a mailbox — in the order a user actually reasons
about them.

The mute toggle goes in a THIRD module-declared slot, above the roster, because
muting is an action ON the guild page while the feed and forum are content IN it.
It renders nothing for a viewer with no preference available, which is a privacy
property rather than a tidiness one: whether a preference EXISTS for a Team
answers "is this person in it", and the guild page is public.

`/unsubscribe/:token` is public and POSTs on mount — the link the user clicked was
a GET, and a GET that mutated would be triggered by every mail-client link scanner.

cbb7339a3a feat(teams): the forum panel core fills, and the operator's controls
The forum had nowhere to live. TEAMS.md 3.1 gave it a CORE page, and phase 3
deleted every core Team page — Teams is a contract primitive and core does not own
the word for one. So the forum follows the activity feed: module-uo declares a
second place on its guild page and core fills it.

TWO slots rather than one, because a slot holds one component and the first fill
wins. Stacking the feed and the forum into a single fill would take from the module
the ability to place core's two contributions separately on its own page, which is
the whole point of the module owning it.

The panel navigates by SEARCH PARAM (?thread=12) rather than by route. A thread has
to be linkable and core cannot mount a route for one — the route belongs to the
module's page — so a search param gives a shareable URL under whatever path the
module chose, with the back button intact and no core route anywhere in it. That is
why the fill is one component holding both a list view and a detail view.

Post bodies arrive already rendered by the server under the current image policy,
which is why they are set as HTML here rather than sanitised again: the body was
cleaned on write with the forum's own profile, and any <img> in it was emitted by
core's own renderer with a fixed attribute set. A client-side sanitiser would have
to strip exactly the tag core just decided to add. The published image mode is read
only to decide which composer to draw — never what renders.

The composer puts an uploaded file's URL into the body as TEXT, not as a tag. The
author never writes markup, which is what keeps the operator's policy enforceable.

The admin panel carries both settings, the always-on help text, and the
confirmation dialog with its two checkboxes and one recorded acknowledgement — plus
the three additions the org lead settled: attribution and staff removal, the
warning that disabling later does not delete existing files, and who "users"
actually means. A stale acknowledgement raises a banner and freezes the settings;
it does not turn uploads off.

5d9d10b245 refactor(teams)!: Teams is a contract, not a surface — invert the slots

PR Checks / server-tests (pull_request) Successful in 35s
Org lead's correction, and it changes what this phase ships.

TEAMS.md §3.1 and §3.5 put four public pages and three nav rows in core. They
should never have been core's. **Teams is the platform primitive that the API
contract exposes; the module builds the pages on top of it.** module-uo builds
guilds; the Rust module that comes next builds clans. Core does not own the word
for a Team, so a core page under a noun core invented would have sat beside
module-uo's existing /uo/guilds saying the same thing in the wrong vocabulary.

Removed: /teams, /teams/:slug, /teams/:slug/roster, /player/teams, the public
and portal nav rows, the `teams` feature flag and the core feature provider that
answered it. /admin/teams stays — an operator inspecting the primitive is
looking at the primitive.

Kept, and unchanged: the tables, the reconciler, the access resolver, the
activity feed, the retention prune, the whole public/player/admin API,
optionalAuth and the roster projection. That is the contract, and it is what
this phase was actually for.

**So the extension slots invert, which is a new direction in MODULE_API §3.7.**
`team.overview` and `team.member.row` assumed core rendered the page. In their
place `registry.declareModuleSlot(id, name)` lets a MODULE declare a place on
its own page and core fill it. Core fills `uo.guild.detail` with the Team
activity feed — the one part of that page core cannot hand over, because only
core can resolve whether the viewer is inside the Team and the public/members
split is a security boundary.

Three things about the inverted direction are load-bearing:

  - the name is namespaced under the declaring module and that is enforced, not
    conventional: it is the only thing keeping two modules off one name;
  - core's fills are applied at MOUNT rather than eagerly. Core's bundle
    evaluates before every module chunk, so when core registers a fill the slot
    does not exist yet — filling eagerly would silently do nothing;
  - a fill for a slot nobody declared is a no-op, never an error. The declaring
    module is simply not installed, which is the ordinary case. That is the
    opposite of §3.7, where an unknown slot throws, and the asymmetry is real:
    there, core declares first, so an unknown name is always a typo.

`Slot` becomes the eighth member of the shared UI kit, so a module renders the
place with core's own error boundary. It matters more here than anywhere else in
the kit: the thing being contained is core's content failing inside the module's
page.

`GET /public/teams/by-external/:moduleId/:externalId` is added because a module
names a Team in its own vocabulary and core keys the feed by slug. The module id
is matched rather than trusted — an external id is unique only within a module.

8f4aff6946 feat(teams): the public Team pages, the two slots and the nav flag
TEAMS.md §3.1–§3.5. Four core pages — the index, a Team's overview, its full
roster and the player portal's "My Teams" — plus the two extension slots a
module adds to them, and the nav rows that lead there.

These are CORE routes, not module ones. A Team is a core platform entity that a
module merely populates, so the whole experience renders on bare core; a module
adds to these pages rather than supplying them.

`team.member.row` is declared with `{ displayName, isLeader, linked }` and not
§3.4's `{ memberKey, userId, displayName }`. The two documents contradict each
other and §3.2 is the one that is a security rule: a slot component runs in the
browser, so those props can only reach it by publishing a game-internal
identifier and a site account id in every public roster response, for every
visitor, module installed or not. Recorded as an amendment.

The presentation logic is split into lib/teams.js with its own tests, following
lib/teamAdmin.js, because these pages have to state differences that read as
bugs unless they are worded deliberately:

  - "37 members · 21 linked" — the gap is information (a character with no site
    account behind it), and the header says what each number IS rather than
    showing both and hoping;
  - an empty roster has three unrelated causes — nobody in the Team, a rung
    that shows nobody, and a module that could not be asked — and reporting the
    last as the first is a statement about the game that happens to be false;
  - a stale projection says how old it is rather than presenting itself as
    current.

`teams` is the first CORE nav row to carry a `feature` since the shard rows left
with the module cutover, and it brings core's own feature provider back with it.
It gates on whether this deployment has Teams AT ALL, not on who is looking —
Team pages are public and the server gates them. It fails open, so an unknown
answer shows the link: a Teams link leading somewhere empty is a far cheaper
mistake than a Team page nobody can find.

5b5006c365 feat(modules): a third slot, nav icons, and api.BASE (phase 3, slice 3)
The three things core owes the client half before it can leave, all additive,
all MODULE_API 1.2.0 → 1.3.0.

`player.invite.accepted` is the third extension slot. Core's invite page owned a
UO game-account step — it read a `gameAccountSignup` flag out of core's own
settings and posted to a shard route — and an invite is a core concept that
staff receive too, so the page stays and its optional next step becomes a slot.
Named for the place, like the other two. Whether there is a step at all is the
filling module's call, made from data core does not have; core keeps the shell,
the skip control and the destination.

`icon` on a nav item, because without it the six extracted UO rows would have
been the only text-only entries in a sidebar where every other row has a glyph.
Core supplies no fallback — an invented one is core making a presentation choice
for content it knows nothing about. `icon` was already among the fields an
override may not touch, so the concept predates a module being able to send one.

`api.BASE` was in §3.5 from the first draft and never actually published.
`request` is fetch-only, so an EventSource builds its own URL, and the shard's
live feed is two of them; the alternative is a module hardcoding `/api/v1`,
which asserts something about core that core has not promised.

`AcceptInvite` is the one legitimate reader of `extensionFor` outside Slot.jsx:
the answer decides a NAVIGATION, not a decoration. Decoration goes inside
`<Slot wrap>`, which is why `hasExtension` stayed deleted.

d667565ae7 refactor(modules): move core's UO page content behind the two slots
All checks were successful
PR Checks / client-build (pull_request) Successful in 26s
PR Checks / server-tests (pull_request) Successful in 29s
PR Checks / bot-install (pull_request) Successful in 8m46s
Core declares site.footer.status and admin.users.detail in main.jsx and fills
both itself, under owner id `core` -- the client twin of registries.registerCore()
and the same trick useShardFlags already uses. The rendered page is unchanged;
what changes is that the content now arrives the way a module's will.

The footer's Shard Status link becomes ShardStatusLink.jsx, and UserDetail's six
UO sections become UserShardSections.jsx. Both are files rather than inline
markup so that the client half of phase 3 deletes a registration and a file
instead of editing a core page under extraction pressure -- which is also what
proves the mechanism before anything depends on it.

The user-detail slot is handed userId and not scope. api.admin.userShard is a UO
binding that leaves core with the client half, so a slot passing it would hand a
module something core is about to delete; an extension builds its own client for
the routes it registered at the other end. Core's own fill now does exactly what
the module will.

Verified in a browser against a real chunk (MODULE_API.md 7.7): a throwaway
module fills both slots and renders its own label and target in the footer with
core's linkStyle, and receives userId on the admin page; a deliberate render
failure is contained to that one spot with the slot named in the console; core's
own fills leave the pages byte-identical to before; and with no module installed
both slots render nothing. Zero CSP reports throughout.

a45a3d120a feat(modules): interleave module nav, derive moderator confinement
All checks were successful

PR Checks / client-build (pull_request) Successful in 8m58s
Phase 2, PR 8 of docs/website/MODULE_SYSTEM.md 2.7 - the nav half PR 7
deferred, plus the two seams 1.4 and 1.5 asked for.

withModuleNav (client/src/modules/nav.js) merges an installed module's rows
into core's three navs BEFORE the admin-override merge, and that ordering is
the design. applyNavOverrides and buildPublicNav are keyed by `to` and drop
any key their base array does not declare, so rows appended after the merge
would be unorderable, unrelabellable and unhideable in Admin - Navigation.
Today's UO rows are all three of those things, so appending would make the
extraction a visible regression for anyone who has ever edited their nav.
Merging first means a module row is an ordinary row downstream: nothing in
navOverrides.js, NavEditor.jsx or the layouts knows a module exists.

MOD_PATHS is gone. Moderator visibility and the redirect that confines a
moderator both derive from each row's own `roles`, in the new plain-JS
lib/adminNav.js (plain so the DOM-less runner can reach it). Two rows move,
both toward what the server already permitted: Dashboard, whose roles had
always named moderator, and My Characters, which is ungated self-service.

That also fixes a defect predating the module system. The redirect was a
THIRD hardcoded list - three path prefixes against MOD_PATHS' five paths -
and they disagreed about /admin/houses, so a moderator who clicked Houses in
their own sidebar was bounced back to Moderation. The derived allow-list is
computed from the BASE nav, never the override-merged one: an override is
presentation and must not move an authorization boundary either way.

The feature seam (modules/features.jsx + modules/featureGate.js) resolves a
row's `feature` against the provider its OWN module registered, so the
namespace comes from the registration and no string carries a parsed prefix.
Core registers useShardFlags under the owner id `core` - the client twin of
registries.registerCore() - so the ten shard-gated header rows already run
through the seam and Phase 3 deletes a registration instead of rewriting
SiteHeader. Every unknown fails open: no provider, a null answer while a
fetch is in flight, or a junk return all show the link, because the server is
the gate and hiding a page from someone entitled to it is the worse mistake.

933 server tests (unchanged - this PR is client-only), 160 client tests
(+37). routes.manifest.json unchanged at 230 routes; the OpenAPI spec
regenerates byte-identical.

Re-ran the MODULE_API.md 7.7 browser smoke, since this is the seam that rule
exists for. A throwaway module registering nav in all three areas and a
provider granting one flag and withholding another: the row lands inside
core's Moderation group rather than an appended block, the withheld row does
not render, a moderator reaches both /admin/houses and the module's admin
page, and an admin can relabel a module row and have it persist and apply.
Zero CSP reports, zero console errors.

e0927bc255 feat(modules): the client registry, window.__rg and the chunk's script injection
All checks were successful
PR Checks / bot-install (pull_request) Successful in 21s
PR Checks / client-build (pull_request) Successful in 30s
PR Checks / server-tests (pull_request) Successful in 1m37s
Phase 2, PR 7 of docs/website/MODULE_SYSTEM.md 2.7 — the client half's
delivery. A module's prebuilt chunk is served, injected, handed core's React
and its UI kit, and its routes are rendered by App.jsx. The registry is empty
on a bare core, so nothing an operator can see changes.

Client:
  - modules/registry.js — registerRoutes/registerNav/registerFeatureProvider,
    with the URL namespace written by core, never by the module
  - modules/shared.js — window.__rg: React, react-dom/client, react-router-dom,
    react/jsx-runtime, the registry, the seven-member UI kit and the request
    primitive, frozen
  - App.jsx reads routesFor for all three areas; nav consumption is PR 8
  - main.jsx publishes the global, then mounts on DOMContentLoaded

Server:
  - the loader validates client.entry and publishes clientChunks() and
    clientEntryUrls(); an entry in the module root is rejected, because the
    directory it sits in is what gets served
  - app.js mounts each chunk at /modules/<id>/ behind the module's state guard
    with no-cache; anything else under /modules is a 404, not the SPA shell
  - htmlShell injects the tag before </body>, so core's bundle runs first
    wherever a bundler puts it

Found by loading a real chunk in a browser, and fixed here: core mounted before
any module chunk had evaluated, because document.readyState during a deferred
script is 'interactive', not 'loading'. Every test passed against that build.
The smoke is written down in MODULE_API.md 7.7.

933 server tests (+23), 123 client tests (+14). routes.manifest.json unchanged
at 230 routes; the OpenAPI spec regenerates byte-identical.
