An edge carries the reference payload of its citer's resolved document, and the
citer is never a selected row under `cited`, so a variant citer slipped past the
selected-row refusal. Edges are now checked by the same rule (typed
NotSupportedException naming the variant), on the paged and the whole-set paths.
Reconcile refused a hop subscriber whose selection selected a variant without
withdrawing it, so it was told again on every store change. It withdraws as the
subscribe path does.

The held index kept one key per value, last writer winning, and RemoveKey dropped
a value outright. Two consequences: removing or changing one of two plain
holders left the other unfindable, and the variant index rule judged a variant
against that lossy view, so a variant could land on a value a plain record still
held and the store then refused to reopen.
- _indexes maps a value to the keys holding it, oldest first. Index, Unindex and
the removal maintain the set. GetByIndex finds the most recently indexed
holder of a value, so removing the winner finds the other (behaviour change for
plain duplicates: it used to find nothing).
- One rule, RefuseVariantIndexSharing, serves both write orders. It reads the
truthful index minus what the commit replaces or removes, plus what it lands.
ResolveOne no longer judges indexes; ClaimIncomingIndexValues, HeldByVariants
and RefusePlainSharingWithVariant are gone.
- A conditional commit merged onto the file is judged by the cache's own
resolution (CacheBackingStore.Judging) on the merged set: records other writers
added, records they removed, and the batch. Another writer's variant sharing a
value with the batch, or a base removal that strands another writer's variant,
is refused with the named refusal instead of writing an unopenable store.
- Shedding is one decision at load. ToStoredDocument resolves the schema once and
returns the report with it; a variant's override of a slot the type lacks is
dropped from the delta there, so flush needs no predicate and every store
reports through the same surface (ReportVariantSheds and OverridesTheTypeHas
are gone). The directory store refuses variants and loads through the same call.

Batch commits on the cache do not reach the database's change stream, so the subscriber's citers were written with database.PutAsync; the variant goes in through UpsertVariantAsync. On the previous source the second subscriber stops receiving after the variant exists (red); it now keeps receiving.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
The selection paths (SelectPage, SelectAll) refused every stored variant before the selection ran, so once any variant existed a hop-bearing subscription threw out of its change handler and went silent. They now refuse only a variant the selection selects; the subscription server delivers that as a typed error and keeps its projection. The database server no longer sends removed for a key the subscriber only ever received as an error. A flatten racing the delivery check is recorded in a comment.

The index rule is about the commit's result, so it now runs for every commit that changes an indexed value: a plain record landing on a value a variant of the post-commit set holds is refused naming both keys and the index (the held index is never trusted; a plain write had already overwritten it). Plain-vs-plain is untouched. A variant sheds overrides of slots its type lacks when it is flushed, as a plain record sheds the member, and the load's report names the slot when the schema itself never had it.

Hand-written and directory-store variants now override their indexed value or
name as the rules require; the subscription test writes its variant through a
committed batch so the file holds it, subscribes by key, and reports what it
saw when it times out.

The unique-index rule refuses a variant that inherits its base's [CultIndex]
value, so the vector's laser-big now carries a code override. Written by the
code under test through the production path; the other runtimes still refuse
it by version and by the laser-big key.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
F3: an override drifts exactly as the same member would on a plain record. A
slot the type dropped is ignored and reported by the store's schema resolution
(LastSchemaMigrationReports), the one surface a plain record uses; a value that
no longer decodes refuses the load, naming the variant and member. The second
report surface (VariantMigrationReports, the per-variant report map, the
catalog slot-name plumbing) is deleted.
F4: an override for a slot the type does not have, or a value that does not
decode as the member, is refused at write. Drift is for type changes after the
fact, not for bad writes. F5: two overrides of one slot are refused.
F2: a variant that shares an indexed value with another record is refused,
naming both keys and the index (the R6 rule extended to [CultIndex]); plain
record duplicate handling is unchanged.
F7: a flatten now resolves against the same batch, so a base edited in that
batch is in the flattened record; and the directory store refuses to load a
variant page as it refuses to write one.
The C1 vector's big variant now overrides its indexed code, as the unique-index
rule requires.

A load or write that landed a variant reached CultNet subscribers as a plain
"added" record carrying the full resolved payload; a later base edit published
only the base, so the subscriber's copy of the variant went stale. Under Q6
CultNet carries no variants until its own cut. Both live paths now refuse a
change whose key holds a variant, after selection and authorization match, and
send the matching subscriber a CultNetErrorMessage naming the variant and its
base. Refused loudly rather than omitted: an omission is a silent hole in the
subscriber's view, and the snapshot path already refuses by throwing.
Tests: a real load through a real RUDP subscription never delivers the variant
as a record and delivers the typed error; the database server's change builder
refuses the same change.

- n=24 fully free problems at cond 1e2/1e3/1e4, and A x 1e6 with unscaled
bounds, converge in at most two iterations (a regression to cap-spinning
fails on the count, not on a clock).
- b = 0 from a far start reaches the optimum instead of the start.
- Warm-start clamp table, free duplicate column gets no step, parallel columns
at absolute scales 1e3 and 1e-3, near-singular free sets confirm once and
stop, near-collinear optimum at A x 1e6, and zero allocation on the invalid,
converged and cap paths (first and second call).

The working iterate now lives in double inside the workspace (WorkspaceLength
4n^2 + 17n); A, b and the API x stay float and x is converted in at the start
and out at the end. The gradient, the free-stationarity check and the KKT test
all run in the double domain, which removes the float noise floor that made the
free-stationarity re-solve spin to the cap on optimal points (cond >= ~20).
A fixed tolerance is no longer the only stopping rule: after a stationarity
miss or a release, a pass that lowers the double cost by no more than rounding
reports Converged.
The tolerance scale is the larger of the gradient at the origin and at the box
point nearest the origin, so it never depends on the warm start; b = 0 with a
far start is no longer judged converged by its own steepness.
Two clauses were equivalent or unobservable and are deleted: the d <= 0 pivot
test (implied by d <= tol * diag) and the dependent[] exclusion from the
free-stationarity check (the progress rule now terminates it).

The three Caching tests that hold a FileShare.Read handle and expect a
delete or replace to fail are marked [Platform("Win")]. They cannot pass
on Linux, where unlink and rename ignore open handles. The Idunn runtime
fixture generator takes its sets as flags or @file response files, so a
consumer such as StreamPixels no longer patches CultLib's example.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The four hard-coded sets become flags, with @file response-file splicing.
A consumer keeps its own .args file instead of committing a patch against
the example. fixture.args carries CultLib own sets; the README documents
the flags. Committed fixture bytes are unchanged.

Reader refusals (v1 header over a variant, payload on a variant, unknown op), a
load that finds a variant flattened by another writer, a re-resolution reaching a
read-only cache, a base removed in the same batch as its new variant, and
plain-record-to-variant refused without the name rule masking it.

A variant needs its base beside it, so a single-record store can never hold one:
that overload's refusal could not fire. SlotNames no longer throws on a catalog
that repeats a slot.

They hold a FileShare.Read handle and expect a delete or replace to fail;
Linux unlink and rename ignore open handles, so they can never pass there and
showed as three standing failures. [Platform("Win")] reports them skipped with
a reason on Linux and keeps them running on Windows. No Linux failure injection
exists: the store names its temp file with a fresh GUID and the suite is
likely root in the verify container, so read-only directories do not fail.

VariantTests drive the cache batch API and the real single-file store. The C1
vector was written by the code under test through that path; C# reads it and
rewrites it byte for byte, and the other runtimes' tests read the same bytes next.
The C0 tests that expected C# to refuse a v2 store now expect what C1 does with
it.

C#, TypeScript, Python, Rust and CultMesh refuse an unknown
cultcache.store.* header and a fifth record slot, naming the version or the
key and schemaId. The silent slot-skipping and C#'s ignored header are
deleted, and CultMesh's second record decoder is gone. Shared vectors are in
tests/vectors/document-variants-c0/. v1 stores stay byte-identical. At base,
the single-file commit's read-modify-write rewrote a v2 store as v1, which
lost data; it now refuses.
Soul passed it. Cross-runtime interop was run and passes. Three C#
Caching tests fail on Linux at both base and tip: they are Windows
share-mode tests (a FileShare.Read handle blocking delete/replace), which
cannot pass on Linux.

A variant record stores [baseKey, overrides[]] in record slot 4 and an empty
payload; the cache resolves it against its base inside the hold that admits it or
any record on its base chain, and re-resolves dependents in the same Apply, so a
base change reaches its variants with contiguous sequences and no stamp. Plain
Upsert at a variant key is refused (Flatten is the explicit way); cycle, missing
base, different concrete type, evicted base with survivors and a name that
shadows the base are refused naming the keys. Overrides of a dropped slot or an
undecodable value are ignored with a warning and reported as compatible drift.
The store writes cultcache.store.v2 only when it holds a variant and reads v1 and
v2. The codec pair CultInspectorModel took becomes CultCodec, shared with the
cache, which needs it to clone documents and overlay override values. The
directory store, CultMesh single-file reads and CultNet row building refuse a
variant by name until their own cuts.

The Rust runtime gains the reference's content chunk messages on the raw
path, CultMeshCdnArtifactManifest with wire-ordered metadata,
normalize_hash, pack_content, validate_manifest,
answer_content_chunk_request (every bad request is answered, byte
identical to the reference server) and fetch_content (one owner of
receiving-side verification; refuses zero-size floods and unnormalised
hashes before any request). Vectors run both ways between C# and Rust.
The operator ruled Q-BP1 A: chunks travel on the session already held.
This is the explicit Rust content path until an authenticated connector
exists.
Soul passed it after two fix batches. cultnet-rs: content 24, cultnet 53,
rudp 7, lib 110. cargo-mutants on content.rs misses 0.

A C# caller that leaves ChunkHash, MessageId or RecordKey null writes msgpack nil; the
reference reads it back as null, treats it as blank and answers found:false. Rust now
decodes nil as blank in content chunk requests, so those requests are answered with the
reference bytes instead of dropped. Three nil vectors from the reference server are
judged by decoding them in Rust. Record two content-plane limits in the parity scope.

The runtime splits into a signer (load, sign, answer a route challenge
locally, no Odin, no network) and an optional Odin presence publisher for
CultMesh-aware services. The signer owns health (reportHealth, starting at
warming), records every warming it signs as a lease target, allows one
signer per frozen authority, and ships a subpath export that does not
load the publisher. Rust judges TS output: committed vectors from
examples/idunn_runtime_fixture.rs, verified by the Rust authenticator and
correlator, including a stateful lease-bound set.
Soul passed it after two fix batches. cultnet-ts has 113/113 tests on
node:24. StreamPixels' web and service call sites move in C2.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
The function took state and lease digest from the caller, so anyone holding the
authority could sign active without reportHealth or assertWriteLease. It is now
private to the signer. Test: the subpath and root do not expose it. Docs:
waitForWriteLease throws out of publish if health is already non-warming;
MAX_RECENT_WARMING_PROOFS=64 is a recorded limit.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
`cultnet-ts/idunn-runtime` exposes the signer and loader alone. Web apps import
it instead of the package root, which also carries the Odin publisher and
node:dgram. The root export is unchanged. Test loads both under a stubbed
dgram: the subpath loads, the root fails.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
The loaded authority is deeply frozen (bind, health contract, Expected,
Activation, identities), so a caller cannot steer what the signer signs; the
typed Buffers that could not be frozen are dropped (Expected canonical bytes,
Activation public key kept as hex only for the load-time comparison). A second
createIdunnRuntimeSigner on the same authority throws, so two signers cannot
emit sequence 1 under one runtimeInstanceId.
Tests: stateful set pinned against Rust (warming, active, degraded), lease
accepted for a route-answered warming, refused for another warming and another
target, one signer per authority, frozen authority.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
The signer holds the last reported health, starting at warming, and gains
reportHealth(state). sign(detail), answerRouteObservation(request) and the Odin
publisher's publish(detail) no longer take a state, so the route answer and the
Odin publish cannot disagree and a fresh signer cannot answer active. Every
warming presence the signer signs becomes a valid write-lease target; the
publisher's recordPublishedWarming is deleted. Tests now assert every committed
stateless vector, dead ones included.

Output of the Rust generator (3c9ce38) on Yggdrasil. Every set is re-enrolled, so

A hostile manifest of empty chunks no longer becomes a request flood: fetch_content
refuses a zero-size chunk beside other chunks, and settles the content hash and every
chunk hash (normalised, non-empty) before the first request.
Every bad chunk request is now answered found:false in the reference handler's
validation order, never refused at decode. validate_message no longer refuses content
chunk requests or responses, so a blank message id or hash, a prefix-only hash and a
negative size reach answer_content_chunk_request. The answer follows the reference's
double normalisation (handler, then CreateRecordKey), which fixes the prefix-only
hash spelling to ArgumentException on 'chunkHash'. The cs vectors gain nine
reference-server answers (blank and whitespace id, blank, whitespace and prefix-only
hash, negative size, record-key case, blank record key, double prefix) and a
metadata-order manifest; Rust answers all of them byte-identically.
Manifest metadata is Vec<(String, String)> in wire order and refuses a duplicate key,
replacing the BTreeMap that re-sorted keys.
Tests pin the surviving mutants: unusable chunk sizes, the payload-length and
claimed-size halves of the chunk check, stable sort at equal offsets, the normalised
hash and canonical key actually sent, and the kind/mime defaults never trimming.

idunn-runtime-authority.ts now loads and signs only: no Odin endpoint, no Odin
dependency check, no RUDP. createIdunnRuntimeSigner signs presence and answers
Idunn's route challenge with answerRouteObservation(request, state), a
synchronous local signature in the state the app reports. The RUDP publisher
moves to idunn-odin-presence-publisher.ts for services that declare
odin.verse-rendezvous, and keeps the Expected-endpoint check.
Deleted: the TS capability-minimum refusal (the Rust correlation records the
typed disagreement), latestPresenceDocument, the forced "active", and the
publisher's redundant health-contract and bind checks. Route validation now
accepts http, tcp and rudp as Rust does; the machine-id falls back to
/var/lib/dbus/machine-id. Tests run against the Rust-written fixtures.
