Struct LoadReport 

pub struct LoadReport {
    pub unknown_globals: Vec<String>,
    pub unresolved_renames: Vec<String>,
    pub anonymous_states_dropped: u32,
}

What Story::load_state couldn’t apply, so a host can surface it rather than have data silently vanish. Globals whose name no longer exists are dropped (no slot to hold them) and reported here. Visit/turn counts are never dropped — counts for scopes the current program lacks are retained harmlessly (unused until/unless the scope returns), so they aren’t reported except when the miss-path alias lookup (M-3, docs/modules-spec.md §5) still can’t place them — see unresolved_renames for a named scope, or anonymous_states_dropped for an anonymous one.

Fields

unknown_globals: Vec<String>

Saved global names with no matching global in the current program.

unresolved_renames: Vec<String>

M-3 rehydration miss-path teaching messages (docs/modules-spec.md §5): a saved fn token, divert value, or visit/turn-count key that didn’t match the current program even after consulting the compiled #@was alias table. Only populated for a program that actually carries alias-table entries (i.e. uses #@was somewhere) — an ordinary content edit with no rename directive stays silent, same as before M-3.

anonymous_states_dropped: u32

Count of saved visit/turn-count entries for an anonymous scope (VisitEntry::path is None — a gather or choice point with no author label, or a sequence, none of which have a name an #@was alias table entry could ever be written against) that could not be placed in the current program (issue #1674, gap 4 of the identity cluster: “anonymous-container state is bounded and reported, not solved”). Unlike unresolved_renames, this is populated unconditionally on a miss — an anonymous scope’s positional id can never be recovered through the alias table regardless of whether the program uses #@was elsewhere, so gating this on Program::has_aliases (the way unresolved_renames is) would make it silent for the overwhelming majority of projects, defeating the point.

The bounded fallout docs/decision-log.md’s 2026-07-27 ruling measured: a once-only choice may reappear as if never chosen, or a sequence may restart from its first branch. Each miss increments this once per saved entry — a scope with both a visit and a turn count that both go unresolved counts as two, since each is independently lost state, not one.

That “bounded” measurement covers the visit/turn-count half only. The same day’s “CORRECTION to the R1 entry” widened the blast radius: anonymous scopes also carry translation units (intl exports keyed by scope id, Option-named), which this field does not account for — it counts only what Story::load_state itself drops.

Implementations

impl LoadReport

pub fn is_clean(&self) -> bool
