wtclaude a4b63d87d2 docs(link): the hue belongs where the files are, and the cache poisons it (Phase 5)
§11.1 is new and carries what phase 5 measured: 49,152 addressable static ids
(not the 81,884 `artidx.mul` declares -- `FileIndex` sizes its table from its
length ARGUMENT), 39,189 with art, 4,244 land tiles, 9,963 + 12,140 empty index
slots, and the whole set at 81 MB decoding in 34 s. That last number reopens the
bulk question and the answer is still no: 108 MB of base64 through a 512 KB
single-slot channel to store 43,433 pictures a shard displays a few hundred of.

Two traps, both §4.5's failure mode -- a confident, plausible, wrong picture:

- `Art.GetStatic` hands back the SAME cached Bitmap and `Hue.ApplyTo` repaints in
  place, so hueing edits the library's own copy: the plain key comes back hued
  from then on, and the next hue stacks. `Files.CacheData` off process-wide fixes
  it and also stops a game server retaining 74 MB of Bitmap. Copying instead does
  not solve the retention, and `new Bitmap(src)` throws on ARGB1555 anyway.

- `PartialHue` (13,259 of 65,536 ids) decides whether a hue repaints every pixel
  or only the grey ones, from a file only the shard has. Item 597 is a wooden
  screen with painted flowers; one mode reddens the flowers, the other the whole
  screen, and both decode. Hence land takes no hue segment and `h0` is not a key.

Plus the namespace trap that compiled: unqualified `TileData` binds to ServUO's
own `Server.TileData`, because the enclosing namespace beats `using Ultima;`.

§14 records what the wire gained -- the `static` and `land` families, `families`
on `assets.sources`, and `assets.fetch` becoming shared plumbing whose family is
DERIVED from the keys (§5 made the key the address; a request naming its family
too would have two places to be wrong and one of them silent). Additive, so the
protocol stays 8 and EXTRACTOR_VERSION stays 2. §15 records that `link` needed
nothing in phases 4 or 5: it forwards verbatim in both directions.

§17.10 is the four org-lead decisions. §12 and modules/uo/SCHEMA.md carry the
website side: `uploads/items/`, per-row `catalog` staleness, and why a key with
no art writes no row at all.

Runic Gateway — Documentation

Central documentation for the Runic Gateway platform. The docs here were extracted from the two code repositories (with full commit history preserved) so they live in one place, independent of either codebase.

Layout

website/    docs from the website core (Node/Express + MariaDB + React/Vite)
modules/    docs for installable game modules — one directory per module id
link/       docs from the ServUO bridge (C# plugin + Rust sidecar + Node WS)
android/    docs from the native Android client (Kotlin + Jetpack Compose)
installer/  docs for the installer that deploys a shard's bridge components
ci/         cross-cutting CI/quality notes

Setting up a shard? installer/INSTALL.md is the operator guide, and the installer is the supported path: one binary deploys the plugin overlay, installs the uo-link sidecar as a service, and hands you the values the website needs.

website/

Doc What it covers
BACKEND_DESIGN.md API contract, DB schema, security model
ARCHITECTURE.md The system diagram — how core, an installed module, the sidecar and the clients fit together
TEAMS.md Teams as a platform primitive: roster, forums, notifications, Discord slash commands and voice — design of record
ENGAGEMENT.md The engagement system: module-declared event triggers, rules, cooldowns, templates and the email / push / in-app delivery channels — design of record
HERO_EDITOR.md Hero canvas editor feature spec
THEMING_AND_NAV.md Admin-configurable theme, brand assets and navigation — build contract
MODULE_SYSTEM.md Making the site game-agnostic: game logic becomes an installable module — design of record
MODULE_API.md The module ↔ core contract: ctx, the register* calls, the client registry and the loader's obligations
UPGRADE_NOTES.md Operator-facing, newest first — the upgrades that need an operator to do something, or that change behaviour quietly enough to be discovered by accident
WIKI_UPGRADE.md Wiki subsystem upgrade notes
SHARD_VISIBILITY.md Who sees which shard data — the admin-configurable audience framework
TRUSTED_DEVICES_MFA.md TOTP two-factor, trusted devices and recovery codes
MODERATION_APPEALS.md Moderation actions, content reports and the appeals flow
SPAWN_ATLAS.md The bestiary / spawn atlas: what the shard contains, parsed from its own ServUO tree
CLILOCS.md UO's id → name table: converting one from your client so items have names
MARKETPLACE.md The player-vendor index: how it is gathered, what it costs, how to tune it
website-README.md Snapshot of the website repo's README (setup/run reference)
test-plan.md The website's test strategy and harness
API_V2_PLAN.md Router domain split + CSP hardening. The split is complete; only the CSP enforce step remains
API_V2_SKELETON.md Superseded — the /api/v2 scaffold that was never built. Kept as the record of why the split was done in place instead
PROJECT_TREE.md Auto-generated snapshot of the repo's tracked file layout

modules/

Documentation for installable game modules aggregates here rather than in each module's repo (MODULE_SYSTEM.md §2.10). The website core knows nothing about any particular game; a module is what makes it a site for one.

Doc What it covers
uo/ module-uo — the Ultima Online module: what it serves, what it owns, and what an operator needs
uo/API.md · uo/SCHEMA.md module-uo's own route surface and the tables it owns
kit-acceptance.md The Integration Kit acceptance run — building a module by following the kit alone, and what it found
rust-dryrun.md A written, deliberately unimplemented module-rust — the test that the module contract generalises past the game it was extracted from
Doc What it covers
INTEGRATION.md How the website integrates with the uo-link sidecar
PROTOCOL_2.md Protocol 2.0 / 2.1 design
v3.md Protocol 3.0 design — shard content/standings streams + the visibility framework
v4.md Protocol 4.0 — guild membership on the wire (guild.roster, guild.leave)
v5.md Protocol 5 — three enrichments in one bump: house.decay's decay schedule, vendor.listing's fee state, and account.login.result. The current protocol, shipped 2026-09-01 as bundle 2026.09.01 (sidecar v2.1.0 + overlay v1.1.0)
v6.md Protocol 6 — idempotent commands, config leases with a shard-side deadline, and the run-scoped participation ledger. On edge; reaches main at the events cutover
v7.md Protocol 7 — the world verbs an event OWNS: creatures, bosses, oracle NPCs, temporary gates, decoration, and the persisted ownership registry behind them. On edge
ADMIN_CONTROLS.md Staff write-plane (kick/ban/broadcast, page queue)
SHARD_PREREQS.md Shard-side prerequisites for the bridge
PLAN.md uo-link build plan
RESEARCH.md Research notes
link-README.md Snapshot of the link repo's README
PROJECT_TREE.md Auto-generated snapshot of the repo's tracked file layout

android/

Doc What it covers
PLAN.md Android client build plan / milestones
COVERAGE_PLAN.md Test-coverage rollout plan
APP_LINKS.md Android App Links / deep-link setup
theme-plan.md Theming plan
THEMING_AND_NAV.md The app's half of admin-configurable theming and navigation — build contract
TRUSTED_DEVICES_APP_HANDOFF.md Trusted-devices app handoff notes
PROJECT_TREE.md Auto-generated snapshot of the repo's tracked file layout

installer/

Doc What it covers
INSTALL.md Start here to set up a shard — the installer deploys the plugin overlay and the uo-link sidecar, registers the service, and connects it to the website. Appendix A is the same thing by hand, still supported
PLAN.md Installer design of record — phases, locked decisions, the bundle/compat-matrix model
PROJECT_TREE.md Auto-generated snapshot of the repo's tracked file layout

ci/

Doc What it covers
SONARQUBE.md The SonarQube setup: project keys, how analysis runs, and how to read a report
