Protected_The claimed address prefix — this Locality's own address, which IS
its coverage prefix (no separate coverage field in v1). A path
string in the addressing namespace, independent of templatePath
and the zone tree. An empty string means "claims nothing" and is
skipped by the coverage index.
ProtectednameDisplay name (e.g. 'Narnia', 'Cair Paravel').
ReadonlystuffRuntime ID for this object (generated using nanoid). This is NOT the MongoDB _id - it's a runtime identifier.
Static_StaticpersistentStaticsubscribableUniversal live-query subscribable fields — fields every Stuff
exposes regardless of mixin composition. Currently just
displayName, a derived render that delegates to
Stuff.getPresentation (Named's name or Visible's
shortDescription, falling through to the baked-in 'something').
Declared here rather than in a substrate-private synthetic
table because every Stuff genuinely owns the concept — there is
no "what if this Stuff has no displayable identity?" case. The
descriptor uses dependsOnFields to declare the leaf source
fields it depends on (name, shortDescription); the substrate
installs precise (FieldChangedEvent, 'field', dep) index
entries automatically. Shadow lifecycle support rides on
ShadowChangedEvent in changes (declared-but-unfired until
the shadow subsystem wires it).
Mixin layers above Stuff add their own subscribableFields for
mixin-owned state; the substrate's prototype-chain walk
hasOwnProperty-checks at every level and unions the
descriptors.
Future universal renders (pronoun, articleName, etc.) land
here too. Mixin-gated renders go on the mixin that owns the
gate.
Consent seam for the residency (self-eviction) sweep. The sweep
asks each idle object whether it may be culled; the object decides,
reading its own knowledge. Default is cull ({ ok: true }) — a
fresh backing class is reclaimable by default and only becomes
sticky when its author deliberately vetoes, the correct bias for a
leak-plugger. Return { ok: false, reason } to veto.
Vetoes layer on the mixin/class that owns the relevant
relationship, composed via super.canEvict(context) — base Stuff
stays permissive and does not reach into Container/Shadow/Avatar/
Exit knowledge. The relational vetoes derive from the R2.x
ref-cleanup rules: an object in an owned/symmetric live-ref
relationship vetoes while its anchor is alive (see
docs/subsystems/residency.md).
Distinct from canDestruct: an object that permits eviction can
still canDestruct-veto, so the sweep's enforce path tolerates a
DestructError (logs + continues). The sweep calls this on the
raw target (via RAW_TARGET) so asking never counts as a touch.
Destroy this object.
Locked down by @CallSecurity(ApiOnly) — only callers under
mud/api/ (in practice, StuffApi.destruct) may invoke it.
@Unshadowable because the unregistration path must always run;
a shadow that intercepts and skips it would leak the object into
the registry forever. @Final because subclass overrides would
defeat the same invariant — the loader hook throws
FinalViolationError at import time on any subclass redefinition.
Subclass cleanup belongs on the optional onDestruct() witness
(consulted by StuffApi.destruct while the target is still live);
refusal logic belongs on canDestruct(). This terminal destroy()
is the unshadowable mark-and-unregister step only.
Read the recency timestamp. Read by the residency sweep — which
calls it on the raw target (via RAW_TARGET) so the sweep's own
introspection never counts as a touch.
Self-presentation — the casual-register render string for this object, the answer to "what does this Stuff call itself?" Three- step resolution:
Named.name if present and non-empty — the object's
proper name ("Alice", "Excalibur", "Town Square").Visible.shortDescription if present and non-empty —
the object's visual identity ("a heavy oak door").For a Globbable stack (quantity !== 1) the count folds in as
an affix — "30 coins" — pluralized via GrammarApi.pluralize
(which honors host-side getPluralForm() overrides for
irregulars). Named takes precedence over Visible so a
Named-with-description renders by its proper name; code that
needs the formal register calls getFullName() when typed as
Named.
Viewer-blind by design. This is the shared baseline every
Stuff exposes; the viewer-aware naming step (recognition /
identification — see
docs/subsystems/belief.md) composes on top
of it. Left shadowable (NOT @Final) so masking / disguise
effects can override the rendered identity via a method shadow.
Build the composable Mml fragment for this object's display name —
the Mml sibling of getPresentation. Mml.ref (and so every
<item> / <name> / … identity tag) renders this, not a raw
string, so a name joins the compose chain as a fragment like
everything else. The label is the already-resolved, viewer-aware
name (recognition runs in the render layer and hands it in).
Return null for the plain default — Mml.ref then wraps the label
in Mml.text, which escapes it exactly once, so player-authored
names / status decoration are safe by construction and the fragment
is never re-escaped downstream. Override to build a richer fragment
(a TPA terminal wraps its name in <color> to tint by state). The
plain-string getPresentation stays the surface for non-prose
consumers (logs, context.note, MQL scalars).
Read seam. Instance method, but unwraps via ProxyApi.unwrap
before reaching the # slot — this inside an instance method
called through the proxy is the proxy, and the # slot lives
on the raw target.
Get the spatial zone. Unwraps via RAW_TARGET because the
# slot lives on the raw target only and this inside an
instance method called through the proxy is the proxy.
Check if this object has been destroyed.
@Unshadowable: the destroyed-state read is a framework invariant —
any shadow that lied about it would let consumers touch a torn-down
Stuff. @Final: subclasses overriding this would defeat the same
invariant; the loader hook throws FinalViolationError at import
time on any subclass that redefines it.
Deregister from the coverage index on destruct / HMR re-clone.
Self-register the claimed prefix into the AddressRegistry
coverage index. Fires once on clone (leaf Ideas clone lazily), and
again on HMR re-clone, so the index never holds a stale node. The
Registry's own boot rebuild covers never-accessed Localities.
Optionalcontext: unknownStamp this Stuff's templatePath and re-key the
byTemplatePath index so future findByTemplatePath lookups
see the new path. No-op when path matches the current value.
Locked down by @CallSecurity(ApiOnly) because flipping a
Stuff's identity post-clone would break FromTemplate
policies and any caller-side caching of template-path
identity. @Final @Unshadowable because the index update has
to run for every successful set — a subclass override that
forgot the index call (or a shadow that intercepted) would
silently desync byTemplatePath.
Unwraps via ProxyApi.unwrap so the #-slot access lands on
the raw target (see comment on #templatePath above).
Set the spatial zone. Gated by FromSpatialZone — only the
SpatialZone class and its subclasses (CartesianZone,
SphericalZone) may call this through the proxy. The
addLocation / removeLocation chokepoints on the zone side
are the legitimate callers; everyone else is rejected.
Clone-time seeding from StuffApi.#cloneInner doesn't go
through this method — it uses the caller-allowlisted
_stampZone seam below.
@Final @Unshadowable because the index of substrate
invariants that consult getZone() (containment's
cross-zone gate, Mobile.traverse, MQL scope walks) trusts
the slot's value; a subclass override or shadow that lied
about it could break those invariants. No legitimate
subclass needs to extend this anyway — the only legitimate
write paths are the SpatialZone chokepoints and clone-time.
Get a string representation of this idea (for debugging). Subclasses should override to provide more specific information.
Refresh the recency timestamp to now. Timestamp-fixed (no caller-supplied value). Called on the raw target by the security gate on every successful dispatch (Phase 2) and by the residency presence walk.
Constructor - calls parent Stuff constructor.
