The live five-rung smoke test of the visibility framework found that Part
A enforced it on the SSE path and on /guilds + /governors, but not on the
remaining public REST reads - so one event was projected live and served
verbatim from stored history.
link/v3.md gains 3.6.1 with the full list (the anonymous acct/webId leak
on /feed, the flattened ownerAcct on /idoc, the dead `houses` field
rules, /feed ignoring live config, the empty-allowlist fall-through, and
the Date-to-{} projection bug), plus the rule it leaves behind: a read
path that returns shard data and does not project is a bug, and every new
Part B/C surface must gate its kind set on live config rather than on
PUBLIC_KINDS.
3.5 also corrected: the table is NOT seeded on boot. An absent row means
"use the compiled default", which keeps the defaults in one place instead
of duplicating them into a seeder that could drift.
BACKEND_DESIGN.md 6.5 records the same as a security contract: rule 1
locks a field by meaning rather than spelling; PUBLIC_KINDS is a
module-load constant and must not answer per-caller questions;
projectFeature walks arrays and plain objects only.
SHARD_VISIBILITY.md gets the admin-facing version - that stored history
answers the same way the live stream does, and that turning live updates
off stops the push, not the reading.

Protocol 3.0 Part A. Admin-configurable, per-feature and per-field
audience control over every shard-derived surface, replacing the static
PUBLIC_KINDS allowlist that used to be the whole boundary.
- SHARD_VISIBILITY.md (new): the admin-facing guide - the ladder, what
each of the ten features exposes, the defaults, the two rules that are
code rather than configuration, and worked examples.
- BACKEND_DESIGN.md 6.5 (new): the same thing as a security contract -
the ladder and how viewerLevel resolves it, the locked acct/webId rule,
the fail-closed kind map, the asymmetric ladder fallbacks, and the
three enforcement points. Plus the shard_feature_visibility schema, the
/public/shard/features route, and the adminOnly tier on
/admin/shard/visibility.
Defaults reproduce pre-3.0 behavior everywhere, with one deliberate
exception which is the leak Part A was written to close: guilds and
governors previously returned the raw stored payload, whose leader and
governor actors carry acct and webId, to anonymous callers.
