Protocol 3.0 Part A follow-up, found by the live five-rung smoke test.
Part A implemented the visibility framework correctly on the SSE path
and on /guilds + /governors, but the remaining public REST reads never
called into it. The result was that one event was projected live and
served verbatim from history:
* GET /public/shard/feed returned the stored payload as-is, so
actor.acct and actor.webId were readable ANONYMOUSLY for every
logged kind - player.death, player.murdered, mob.killed,
quest.complete, skill.gain, fame/karma.change, mob.login/logout,
guild.join. Broader than the guild-leader leak Part A set out to
close, since it covers every player rather than board holders.
* GET /public/shard/idoc returned ownerAcct - the house owner's game
account - to anonymous callers.
* The `houses` field rules (owner/price -> staff) were dead config:
neither getIdoc nor getHouses projected, so an admin could set them
in the panel and nothing happened.
* /feed filtered on PUBLIC_KINDS, a module-load constant derived from
the compiled DEFAULTS, so live audience changes did not reach it.
With `guilds` moved to staff, /guilds 403'd while /feed happily
served guild.join to anonymous.
Four fixes, all at the root rather than per-route:
1. Rule 1 now matches a field's MEANING, not one spelling. The wire
nests actors (leader.acct) but the read models flatten them
(shapeHouse -> ownerAcct, shapeGuild -> leaderWebId), and an
exact-key check missed every flattened one. isLockedField() locks a
key that is or ends in acct/webId, case-insensitively, so it fails
closed for shapes not yet written. The admin PUT rejects those
spellings too - `ownerAcct` is no longer configurable.
2. visibleKinds(level, config) resolves readable kinds from the LIVE
config; getFeed uses it and projects each row against its own kind's
feature. Deliberately independent of the `stream` flag, which governs
SSE fan-out only - so market history stays readable with its firehose
off. This makes the set a superset of PUBLIC_KINDS by exactly the two
vendor kinds.
3. getIdoc/getHouses/getChamps/getPresence project, so every shard
surface honours the same config.
4. shardEvents.db.list treats an EMPTY kinds array as "serve nothing".
It previously fell through to the unfiltered query, so a fully-gated
config would have dumped the whole event log, staff audit included.
Also fixes a bug introduced while wiring this up: projectValue recursed
into any object, so a Date column came back as {}. It now walks arrays
and plain objects only. The unit tests used JSON fixtures and could not
have caught it - the live /idoc read did.
Verified live against MariaDB + a stub sidecar, all five rungs: 13
routes x 5 rungs, defaults reproducing pre-v3 access exactly, zero
acct/webId below admin on any read, unmapped kinds (staff.command,
cheat.detect, login.attempt) reaching only admin on SSE, and audience /
enabled / stream changes taking effect live on an already-open stream.
Tests: 487 server (+9). Swagger regenerated; route manifest unchanged.

Protocol 3.0 Part A. Replaces the static PUBLIC_KINDS allowlist - which
was the entire public/admin boundary - with per-feature, per-field
audience control an admin owns from Admin -> Shard Visibility.
Closes a live leak. BridgeJson.Actor() writes acct and webId;
shapeGuild() returned the stored payload verbatim; GET
/api/v1/public/shard/guilds is anonymous. Guild leaders' game account
names and website user ids were readable by anyone, and the same path
existed for governors. Both are now projected.
The ladder is anonymous < logged_in < player < staff < admin, each rung
implying the ones below. Staff satisfy `player` without a linked account
(as /player/* already does); `editor` is a content role and gets no
shard privilege, since mapping it to staff would silently widen what
editors see.
Two invariants are code, not configuration, and both reject rather than
silently ignore:
1. acct/webId are admin-only always - not configurable, discarded on
read as well as rejected on write.
2. A kind absent from KIND_FEATURE never reaches anyone below admin.
Fail closed, so a shard emitting a new event degrades to staff-only
rather than to public.
Enforcement is three points over one config: requireFeature() on routes
(404 disabled, 403 out-of-rung) plus field projection; per-connection
filtering on SSE, where a subscriber's rung is resolved once at subscribe
time and frozen so a long-open stream cannot gain privilege; and
/public/shard/features so the SPA hides links it cannot follow.
PUBLIC_KINDS still exists and is still exported (/feed filtering,
notificationStreams) but is now derived from the kind map, so the two
can no longer drift. Defaults reproduce pre-3.0 behavior exactly - a
test pins the derived set against the old allowlist.
Also fixes an SSE resource leak found while testing: a client dropped
because its write threw was removed from the bucket but its keepalive
interval was never cleared, firing forever on a dead socket. Both paths
now go through one drop().
Tests: 478 server (33 new across shardVisibility + shardBroadcast),
43 client. Route manifest and OpenAPI spec regenerated.
