docs(android): scope M11 — Protocol 3.0 shard parity for the app

The v3 work added four shard features and an admin-configurable visibility
framework the Android client knows nothing about. v3.md §10 deferred the app
side as a follow-up; re-examining it before the cutover found the gap is wider
than nav hiding:

  - no consumer for any of ruleset / leaderboards / market / atlas,
  - no `points` block on the character sheet (§7.3),
  - no cliloc-resolved item names (§8.6), and
  - shard nav gated on session role alone, so an admin who disables a feature
    or raises its audience leaves the app rendering entries that 404/403 into a
    generic error where the web client hides them.

Scoped as PLAN.md §9 M11 in two PRs (the visibility rules + read-model adds,
then the four screens), with the traps a real shard exposes recorded inline:
uncapped `maxPoints: 0`, cliloc-named boards with a null `nameString`, skill
caps in tenths, the required market staleness banner, the market stream being
off by default, atlas delays in seconds, and `points`-count vs `spawners`-list.

edge → main is held until both land so web and app surface the same shard on
the same day. Neither PR is coupled to the merge order — on a pre-v3 website
every new route and /public/shard/features 404s and the app falls back to
today's behavior — so holding the cutover is a schedule decision, not a
technical dependency.

Also records two things verified as already correct, so they are not
re-derived: the app's SSE request rides the authenticated client (same audience
rung as the same account on web), and every shard DTO is nullable-with-defaults
(field projection cannot cause a decode failure).

+12. **M11 — Protocol 3.0 shard parity** (post-v1; scoped 2026-07-30). The website's Protocol 3.0 work
+    added four shard features and, with them, an **admin-configurable visibility framework** the app
+    knows nothing about. `link/v3.md` §10 deferred the app side as a follow-up; it is now scoped
+    deliberately, and **the v3 `edge` → `main` cutover is held until both parts land** so web and app
+    surface the same shard on the same day (decided 2026-07-30).
+
+    Neither part is coupled to the cutover *merge order*, which is what makes holding it a schedule
+    decision rather than a technical one: against a pre-v3 website every new route and
+    `/public/shard/features` simply `404`s, and each consumer below falls back to exactly today's
+    behavior. The app declares no protocol version and never talks to the sidecar.
+
+    - **Part 1 — the visibility rules + the read-model adds.** The security-shaped half, reviewed on
+      its own:
+      - `GET /public/shard/features` → `{ level, features[] }`: the features **this caller** may reach.
+        A new singleton cache mirrors the web client's (`lib/useShardFeatures.js`): per-viewer but
+        stable for a session, invalidated on sign-in/out and on a server switch.
+      - `MenuEntry` gains `feature: String?` beside its existing `access`, so the one declarative menu
+        (§5) filters on the session role **and** the shard's live feature config. While the lookup is
+        in flight or has failed, **show everything** — the same deliberate fail-open the web client
+        takes, because the server gates regardless and a nav that flickers in on every load is worse
+        than a link that briefly `403`s. The gate is server-side; hiding is presentation.
+      - **`404` and `403` mean different things here** and neither is a generic error:
+        `requireFeature` `404`s a *disabled* feature (deliberately not disclosing that it exists) and
+        `403`s a viewer *below its audience*. Both render "not available on this shard", alongside the
+        existing `503` = shard offline (§7).
+      - **The `level` from `/features` is authoritative — do not re-derive the rung from the role.**
+        The server's ladder is `anonymous → logged_in → player → staff → admin`, where `player` means
+        *a linked game account* and staff always satisfy `player` (the same superset rule `Menu.kt`
+        already encodes as `isPlayer || isStaff`).
+      - **`char.profile.points`** → the "Loyalty & Points" block the web character sheet gained:
+        `CharProfileDto.points[{system, nameString, points, maxPoints, rank?}]`. Three traps, all of
+        them things a real shard does and a fake one does not (`v3.md` §7.5): `maxPoints == 0` means
+        **uncapped** and is the *common* case, so nothing may divide by it; `nameString` is usually
+        `null` because most systems name themselves with a cliloc, making the humanise-the-`system`-key
+        path the **primary** one rather than a fallback; and `rank` is absent unless the shard runs
+        `PointsProfileRank=true` — absent and "unranked" are different answers.
+      - **Cliloc-resolved names** (`v3.md` §8.6, already live on the website): `EquipmentDto` gains
+        `name` + `clilocName` and `TitlesDto` gains `rewardResolved`, so equipment stops rendering as a
+        layer or a bare id. Precedence is `name → clilocName → layer`: a player-given name outranks the
+        resolved type name, and the server applies the same order. A shard with no cliloc table
+        configured sends neither field and the sheet renders exactly as it does today.
+      - `ActorDto` keeps its `acct` / `webId` fields (nullable, so nothing breaks) but its KDoc stops
+        describing them as available: they are **locked to the admin rung**, always, and stripped from
+        every response below it.
+    - **Part 2 — the four new screens**, each hidden by its feature name in the menu:
+      - **Rules** — `GET /public/shard/ruleset` (`ruleset`). A `null` body means "the shard has not
+        published its ruleset yet", which is a different state from the feature being disabled. Every
+        block is optional and omitted when its system is off. **`caps.skill` / `caps.totalSkill` are in
+        tenths** (1000 = 100.0) and must be converted — the raw number is actively misleading, not
+        merely unhelpful. Live via the `world.ruleset` frame, which is on the public stream by default.
+      - **Leaderboards** — `GET /public/shard/points`, `/points/:system` (`leaderboards`). The same
+        `maxPoints`/`nameString` traps as the profile block. Live via `points.board`.
+      - **Market** — `GET /public/shard/market` (`q`, `minPrice`, `maxPrice`, `itemId`, `map`, `region`,
+        `sort`, `limit`, `offset`), `/market/meta` for the filter options + staleness, and
+        `/market/vendors/:serial` (`market`). Four things this screen must get right: it is the site's
+        first **rate-limited** public endpoint, so handle `429` the way the contact form does; the
+        *"prices last refreshed N minutes ago"* banner is **required, not decoration** — the shard
+        sweeps vendors round-robin, so a listing can legitimately be a full cycle stale and a page
+        implying live prices sends people to an item that sold twenty minutes ago; a `truncated` shop
+        must say so; and `location` is a **nested object** that an admin may gate away entirely, which
+        the vendor screen renders as "hidden by the shard" (a real answer) rather than as blank
+        coordinates — same for `ownerName` / `ownerSerial`. **The `market` SSE fan-out is off by
+        default** (a live firehose of vendor inventories would be the site's biggest bandwidth
+        consumer), so the screen is a plain paginated read and must never depend on live frames.
+      - **Atlas** — `GET /public/atlas/{creatures,creatures/:slug,regions,landmarks,champions,meta}`
+        (`atlas`). Note the path: `/public/atlas`, **not** `/public/shard` — the atlas is static shard
+        *content*, not live shard *state*, and unlike `/shard/*` it **is** `siteMode`-gated like
+        `/posts` and `/wiki`, so a site in maintenance mode withholds it independently of the sidecar.
+        Two units/naming traps from `v3.md` §6.3: respawn delays are **seconds** throughout, and
+        `points` is a *count* on the search route while `spawners` is the *list* on the detail route.
+    - **Verification** — the five-rung walk (`anonymous`, `logged_in`, `player`, `staff`, `admin`)
+      against a local website on the cutover branch, per
+      [`../link/v3.md`](../link/v3.md) §11 and the shard-visibility smoke harness; plus one pass with
+      **every feature disabled** in Admin → Shard Visibility, confirming the app *hides* each surface
+      instead of erroring on it. Unit tests cover the menu filter (role × feature set), the
+      `404`/`403`/`503` mapping, and DTO decode for each new shape.
+    - **Excluded**, in the same class as M10's exclusions: the admin *configuration* panels — Shard
+      Visibility, Spawn Atlas and Cliloc import — alongside the hero/CMS block editor, Discord-bot
+      config, uo-link config and OAuth-provider setup.
