-# CultNet write receipt (specification)
-
-Status: specification. No runtime implements it yet; the conformance follow-ups below do.
-Rules: Heimdall's ruling of 2026-11-08 (a write completes on its result frame; an ack or a return is not admission).
-Files here: `cultnet.write-admitted.schema.json`, `cultnet.error.v1.schema.json`, `write-receipt-vectors.json`. They move to `contracts/cultnet/` when the first runtime implements them.
-
-## The problem
-
-A put or delete today has two answers on the wire: nothing (admitted, or the server never read it) and `cultnet.error.v0` (refused, with no id saying which write). A transport ack proves delivery. Clients that completed on the ack, or on a window with no refusal, reported refused writes as done (CultLib #55 to #58 bound this with a result window; this spec replaces the window with an answer).
-
-## Frames
-
-**`cultnet.write_admitted.v0`**: `{ schemaVersion, messageId, operation: "put"|"delete", schemaId, recordKey }`, every key written, none nil. Sent once a put or delete is admitted. The id echoes the write's `messageId` byte for byte; `operation`, `schemaId`, `recordKey` echo the write.
-
-**`cultnet.error.v1`**: `cultnet.error.v0` plus a required `messageId` (string or nil). The code enum is v0's plus `limit_reached` (see Remembered-write limits); `cultnet.error.v1.schema.json` is the authority for the closed set. Sent in place of `error.v0` to a receipt-capable connection. `messageId` is the id of the request the error answers; nil only when the frame was unreadable or carried no id.
-
-Why a new error version and not an extra key on v0: the v0 schema is closed (`additionalProperties: false`) and the TypeScript decoder (Ajv over the closed schemas) rejects unknown keys and unknown `schemaVersion`s, and `parseCultNetMessage` throws on an unknown version; Rust's decoder errors on an unknown version too. Unknown-key tolerance of the Rust, Python and Kotlin error decoders was not checked, so none is assumed, so a surprise key or frame breaks an old client's whole receive path. Old clients are therefore never sent either new frame. This reverses the "old clients ignore it" assumption, which is false for today's decoders.
-
-## Capability: opting in
-
-A connection is receipt-capable when its `cultnet.hello.v0` (sent before its first write; the schema channel is reliable and ordered) lists both `cultnet.write_admitted.v0` and `cultnet.error.v1` in `supportedMessageVersions`. A server MUST NOT send either new frame to any other connection, and answers it exactly as before (no receipt, `error.v0`). A receipt-capable server lists both in its own hello, so a client can tell a legacy server from a receipt server that has not answered yet. A client that sends no hello gets legacy behaviour. A server advertises the two frames in its hello only if it implements the receipt rules end to end.
-
-**The capability changes framing only; it never authorizes.** A hello authenticates nothing and grants nothing: who may write, and which keys, is decided by the server from the transport-authenticated actor exactly as without the capability. Declaring the capability never makes a refused write admitted, never widens an actor's authority, and never changes what a write does; it selects only which frame the answer arrives in.
-
-## Server rules
-
-1. **One answer.** For every put or delete on a receipt-capable connection the server sends exactly one of `write_admitted` or `error.v1`, carrying that write's `messageId`. Never both, never two different answers.
-2. **After the commit point.** `write_admitted` is sent only after the write is committed by the same rule that makes it visible to readers. Receipt of the bytes, parse, or authorisation alone is not admission.
-3. **Id on every refusal.** Every refusal of a write, whatever its code (`write_not_authorized`, `message_invalid`, `unowned_schema`, `unsupported_schema_version`, shard authority errors, ...), is an `error.v1` whose `messageId` is the write's id. When the frame is readable enough to find the id, it is found; `message_invalid` for a missing or ill-typed field still carries the id. Nil only when no id can be read.
-4. **Batches.** There is no batch frame; a batch is N writes, each with its own `messageId`, each answered under rules 1 to 3. A failed batch names its member by that id. A server may not collapse a batch into one answer.
-5. **Identity and idempotent resend.** A `messageId` is unique per authenticated actor and session: the client mints it, never reuses it for different content in that session, and a server never accepts the id of one actor as the id of another. The server's dedupe key is `(actor, messageId)`, where *actor* is the transport-authenticated identity, never a name the hello or the frame claims. Alongside the key it keeps the **content hash** of the write and the answer it gave. The content hash is SHA-256 of the MessagePack array `[operation, schemaId, recordKey, payload]`, where `payload` is the raw document payload as a MessagePack `bin` for a put and nil for a delete (the vectors give worked hashes). **Scope: at least the session.** The key lives for the life of the session it was made in, and a server may bound how many writes it remembers per session (see Remembered-write limits; a server never forgets an id it promised to answer). A server MAY keep the key longer for the same actor, up to `DEDUPE_RETENTION_MS` (10 minutes), but a client MUST NOT rely on it: **a reconnect is a new session, and a resend on the new session is a new write.**
-   - Same key, same content hash, answer was `write_admitted`: answer `write_admitted` again with the same body. The write is not applied twice.
-   - Same key, same content hash, answer was a refusal: the same refusal again.
-   - **Same key, different content hash: refuse `message_invalid` (details `field: "messageId"`) and never re-send the old receipt.** Old receipts are for the old content; showing one for new content would report an unapplied write as admitted. The original write's state is unchanged.
-   - **Id size.** A write's `messageId` is at most 256 bytes of UTF-8. A longer id is refused `message_invalid` (`details.field: "messageId"`, the refusal's `messageId` the id as received, text fixed per Fixed texts) BEFORE anything is remembered: no table entry, no digest, no budget charge. Such a refusal is therefore not replayed from the table; a resend is refused afresh, identically.
-   - **What is remembered.** Per entry a server keeps only fixed-size digests (SHA-256) of the `messageId` and of the content hash, plus the answer (`admitted`, or the refusal's code and details). Memory per entry is bounded independent of id length and payload size. Lookup compares digests.
-   - **Remembered-write limits.** The per-session table holds at most 1024 entries. A server MAY also enforce a server-wide memory budget across all sessions (reference: 32 MiB of remembered entries). A NEW write (a key not already in the table) that would exceed either bound is refused `limit_reached` for that write alone, `messageId` the write's id, `details` all null; the write is not applied and the session continues. A resend of a remembered key is still answered from the table.
-   - **Limit refusals are remembered.** A `limit_reached` refusal is remembered like any other: a resend of the same id and content hash replays `limit_reached`. No slot is freed mid-session, so an id refused at a bound never becomes admitted later in that session (a server at the cap keeps the refused digest pair in a bounded refusal set of at most 1024 per session, outside the entry budget; past it, a further new write is refused `limit_reached` without being remembered, and the session refuses every id it has not seen for the rest of its life, even if a server-wide budget has since freed, so a refusal that was not remembered is never followed by an admission of the same id). The client mints a new id on a new session.
-   - **Required fields.** A put or delete whose document or `schemaId` is null or missing is refused `message_invalid` with `details.field` `"document"` or `"schemaId"` (the first missing in that order) and fixed text; the write is not applied. A `schemaId` or `recordKey` that is empty or only whitespace (present but names nothing) is not "missing": the write is refused `message_invalid` exactly as a frame that does not read, with `details.field` `"message"` and the write's id (vector `error_v1_empty_schema_id_is_unreadable_and_names_the_write`), and is never applied; a server must not hand it to its store.
-   - **Fixed texts.** The `error` string of these refusals is fixed, so vectors can compare it: `message_invalid: messageId exceeds 256 bytes`, `message_invalid: document is required`, `message_invalid: schemaId is required`, `message_invalid: receipt sessions require the reliable channel`, `limit_reached: the session's remembered-write limit is full`.
-   - **Reliable channel only.** A write is accepted on a receipt session only on a channel that is reliable and not sequenced (reliable ordered and reliable unordered both qualify; a sequenced channel drops superseded packets, so a write on it can vanish without trace). A write arriving on any other channel is refused `message_invalid` with `details.field: "channel"` (the transport profile's word for it) and fixed text. Receipts and refusals travel the reliable channel; a write that could be lost without trace cannot be answered once.
-   - Past the session (or a server's longer retention, if it keeps one) a resend is a new write.
-6. **Forwarded writes.** A server that forwards a non-primary write answers the original peer only with what the primary answered: the primary's receipt becomes `write_admitted` with the original id, its refusal becomes `error.v1` with the original id. If the forward gets no answer the server relays nothing: no receipt, no error, no synthesized refusal. The client's own rule below then reports the write as unconfirmed. A forwarder never turns an absent or ambiguous primary answer into an admission.
-7. **Looks alike.** An admitted and a refused write differ in `schemaVersion`; a receipt has no `error`, an `error.v1` has no admission. A transport ack is neither.
-
-## Client rules: three outcomes
-
-A write settles as exactly one of:
-
-- **admitted**: a `write_admitted` whose `messageId` is the write's.
-- **refused**: an `error.v1` whose `messageId` is the write's, carrying its `code` and `details` as the typed error.
-- **unconfirmed**: nothing settled it. Reasons: `window_elapsed` (the result window ran from the *send* and passed with no answer; see Result window), `session_ended` (the peer closed the session, or it ended, before the write was answered) and `local_send_failed` (the client's own send of this write failed). A local send failure is never reported as refused: no server answer exists, and the write may or may not have left the machine. Unconfirmed is not success and not refusal. APIs that return a value return the tri-state; APIs that throw throw a distinct refused error and a distinct unconfirmed error and return normally only for admitted. A caller that needs admission treats unconfirmed as not admitted. Resend with the same `messageId` and unchanged content, **on the same session**, is safe against a receipt-capable server (rule 5). After a reconnect the resend is a new write, and a legacy server may apply a resend twice: the caller resends only writes that are idempotent by record key (a put of the same content to the same key, a delete of a key), and reads the record back before resending any other.
-
-**Result window.** Two named constants (also in the vectors): `RECEIPT_RESULT_WINDOW_MS = 5000`, the default against a receipt-capable server (its hello lists both frames); `LEGACY_RESULT_WINDOW_MS = 500`, used only as the fallback against a server whose hello does not list them (or that sent none). The window runs from the send. A receipt-capable server that has not answered within its window is reported as unconfirmed like any other; clients log it as a server that missed its window.
-
-**Late answers.** An answer for a write that already settled `unconfirmed` does not change what the caller was told, but the client records it on the write: a late `write_admitted` makes the write's recorded state `admitted_late`, a late refusal makes it `refused_late`. The write handle exposes that state, and a caller that got `unconfirmed` MUST consult it (and the record) before resending: it must not blind-resend a write that was admitted late. A resend on the same session with the same id and content is harmless on a receipt-capable server (rule 5); across a reconnect the caller follows the idempotence rule above.
-
-**Legacy answers.** An `error.v0`, or an `error.v1` with nil `messageId`, names no write. It is attributed to a write only when exactly one write on the connection is unanswered; it then refuses that write. With two or more unanswered writes it settles none of them and each ends unconfirmed at its window. A frame naming a `messageId` that is not in flight settles nothing.
-
-**Batches can commit partially.** A batch is N independent writes with no atomicity: some members may be admitted while others are refused or unanswered, and nothing is rolled back. The client reports each member's outcome and a batch result is only their set: admitted if every member is admitted, refused if any member is refused (naming the members), otherwise unconfirmed (naming the unanswered members). The caller owns retry: it resends exactly the members that are not admitted, with their original ids.
-
-## Changes to what #55 to #58 shipped
-
-Those clients complete *successfully* when the window ends with no refusal. Under this spec that case is `unconfirmed`. The TypeScript one-shot writer (#62) already reports it so: it resolves `admitted` only on a `write_admitted` carrying the put's id, and no other frame, a put echoed under the same id included, ever counts as admission. A caller whose server cannot answer a write yet (Odin, until it is receipt-capable) opts into the explicit send-only mode per call (`sendOnly: true`), which resolves the distinct outcome `sent` once the transport has acknowledged the put and never `admitted`. The Idunn presence publisher is send-only by its own function (`sendPresenceDocument`, not the `sendOnly` option): the same `sent` result, plus a rejection if a refusal naming the put (or naming nothing) arrives by the transport ack. Receipts and send-only are both opt-in, neither is the default. The C# and Rust clients of #55 to #58 keep the window-success until their conformance work lands, and callers of those must not read it as admission.
-
-## Vectors
-
-`write-receipt-vectors.json`: `constants` (the named windows and retention), `contentHash` (worked dedupe hashes), `dedupe` (server replay cases for rule 5), `wire` (MessagePack hex plus the decoded message for each new frame; the bytes are spec-authored with msgpack-python and every runtime's first conformance PR re-captures them with its own encoder and must match), `schemaInvalid` (frames that must be refused by a validator, each with why), and `scenarios` (event replays with the outcome each write must settle as; the clock is abstract; each case names its window constant). A conformant client passes every scenario; a conformant server's answers for the same inputs satisfy server rules 1 to 7.
-
-## Conformance status
-
-| Server class | Advertises both frames | Server-wide memory budget (MAY, Remembered-write limits) |
-|---|---|---|
-| `CultNetDatabaseServer` | yes | not implemented: only the per-session limit of 1024 applies |
-| Shard write forwarder | yes | not implemented: only the per-session limit of 1024 applies |
-| Rust RUDP document server | yes | implemented (32 MiB default, `max_remembered_write_bytes`) |
-| C# RUDP schema server (`CultNetRudpSchemaServer`, `src/GameCult.Networking/CultNetRudpSchemaServer.cs`) | no | n/a |
-
-Advertising is per server class, not per transport. A class advertises both frames in its hello only if it implements the receipt rules end to end; the C# RUDP schema server stays "no" until it answers writes with receipts.
-
-## Conformance follow-ups (not in this PR)
-
-C# server and client, Rust, TypeScript, Python, Kotlin: emit and parse the two frames; hello capability; tri-state client outcome; replace the #55 to #58 window-success; re-capture the wire vectors in each runtime. Server write paths include the shard write forwarder (rule 6) and the Odin catalog.

 All notable changes to `@gamecult/cultcache-ts` are recorded here, following
 [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).
 
-## [0.15.0]
+## Unreleased
-
-0.14.1 and 0.14.2 were never tagged or published; this entry carries them with the Unreleased work, and `cultcache-ts-v0.14.0` is the previous release.
 
 ### Breaking
 
 - A single-file store written as `cultcache.store.v3` is read and written: a record that holds an element id (an owned list element with an `[CultElementId]` member, carried through every write) marks the store v3, and a v3 store is carried through a rewrite with its ids. A runtime from before this change refuses a v3 store by name.
 - A single-file store refuses a zero-byte file as `StoreUnreadableError`; only a path with nothing at it is an empty store. A header this runtime does not read is refused, and the refusal echoes the header only as `cultcache.store.v<digits>`.
-- A write over a file the reader refuses (`StoreUnreadableError`, from `push`, `pushAll` and `delete`) refuses and leaves the file as it is. A flush used to replace such a file. A write set cannot merge with a disk it cannot read, so the file is repaired or removed by its owner before the store writes again. A full `pushAll` over a file with no readable stamp does not replace it: the reader refuses it. The stamp rule has one owner, `refuseUnreadFormat`, asked only by the one reader that every write consults under the lock. The reader judges the stamp from the header before it decodes the body, so a newer store is refused by name whether or not its body is whole.
+- A write over a file the reader refuses (`StoreUnreadableError`, from `push`, `pushAll` and `delete`) refuses and leaves the file as it is. A flush used to replace such a file. A write set cannot merge with a disk it cannot read, so the file is repaired or removed by its owner before the store writes again.
+- This reverses the 0.14.2 `pushAll` fix in two ways. A full `pushAll` over a file with no readable stamp no longer replaces it (healing it): the reader refuses it, and the file is left as it is. And a `cultcache.store.v3` stamp is read, not refused. The stamp rule has one owner, `refuseUnreadFormat`, asked only by the one reader that every write consults under the lock. The reader judges the stamp from the header before it decodes the body, so a newer store is refused by name whether or not its body is whole.
 - A dangling symbolic link at the store path is an I/O error with code `ENOENT`, not an empty store.
 
 ### Added
 
 - `@gamecult/cultcache-ts/browser`, also what a bundler resolves for the package root under the `browser` export condition: the root surface without `SingleFileMessagePackBackingStore` and `readSingleFileStore`, so it imports no `node:*` built-in and no `koffi` and bundles with esbuild `platform: "browser"`. The Node entry exports exactly what it did.
+
 - `readSingleFileStore(path)`, the one synchronous reader of a single-file store, for consumers that must read a store file rather than decode it themselves. `pullAll`, `push`, `delete` and `pushAll` ask the same reader.
 - `StoreUnreadableError` for a store file this runtime cannot read, `SchemaConflictError` for a write the catalog cannot describe, and `schemaIdentityOf` with its result type `CultCacheSchemaIdentity` (`schemaId`, `schemaName`, `schemaVersion`, `compatibleSchemaIds`), the one derivation of a definition's identity.
-- The document payload codec, exported from `@gamecult/cultcache-ts/document`: `decodeDocumentPayload`, `encodeDocumentPayload`, and the two named byte escapes `documentPayloadFromBytes` and `documentPayloadBytes`.
 - `SingleFileStoreRead`, exported: the result type of `readSingleFileStore` (`absent`, `format`, `envelopes`, `repairedLegacyPayload`).
 - `CultCacheInspection.format` is `StoreFormat | "legacy.envelope-array"`: it reports `cultcache.store.v3` for a v3 store.
 - A soft `pushAll` writes only where nothing is at the path, leaves a store it can read byte for byte, and refuses what the reader refuses.

 ### Changed
-
 - The Windows replace is a POSIX-semantics rename first (it lands while C# and Rust readers
   hold the store open), falling back to a write-through `MoveFileExW`, with 25 attempts 20 ms
   apart on errors 5, 32 and 33. Writers wait up to 30 s for the lock.
 - Opening a legacy store that needs healing rewrites it under the lock, from a read taken
   under the lock.

-authority grants it, mirroring C# `ICultNetRemoteWriteAuthority`. Before this, any connected peer could overwrite
-or delete the node's documents. The refusal is a typed `cultnet.error.v0` with code `write_not_authorized` and the
-record key in `details`; an authority that raises, or returns no decision, refuses too.

-Known residual: ungranted peers can still distinguish registered from unregistered schemas by timing (the node resolves the
-schema before the gate so the authority sees the canonical id); the refusal itself is identical.

+All notable changes to `cultmesh-ts` are recorded here, following
 [Keep a Changelog](https://keepachangelog.com/en/1.1.0/).
 
 ## Unreleased
 
-### Added
-
-- `publishRudpDocumentOnce` takes `writeReceipts: true`: it sends a hello listing `cultnet.write_admitted.v0` and `cultnet.error.v1` and, against a server that lists both back, resolves only on that write's `write_admitted`, rejects with `CultMeshRudpWriteRefusedError` (now also carrying an `error.v1`) on its refusal and with the new `CultMeshRudpWriteUnconfirmedError` (`reason`: `window_elapsed` after 5000 ms, `session_ended`, or `local_send_failed`) when nothing settles it. Without the option, or against a server that did not advertise, there is no hello and the window is 500 ms; a put nothing settled in it is unconfirmed too, no longer "published" (**behaviour change**: a server that applies a put but answers nothing now yields `CultMeshRudpWriteUnconfirmedError`, as the spec requires). A legacy server's echo of the put's id is not admission: only `write_admitted` is. The flush that sends the put is bounded by the result window, and a send not acknowledged by then is `local_send_failed`. `resultWindowMs` overrides either window. `publishRudpDocumentAndWaitForReceipt` is not changed.
-
 ### Breaking
 
-- `publishRudpDocumentOnce` no longer treats a window with no refusal as published: a put nothing settled in its result window (500 ms, or 5000 ms against a receipt-capable server) rejects `CultMeshRudpWriteUnconfirmedError`, and a legacy server's echo of the put's id is not admission. It now resolves `"admitted"` (only on a `write_admitted`) or `"sent"`. **Migration:** a caller whose server cannot answer a write yet (for example Odin, until it is receipt-capable) passes `sendOnly: true` per call and treats `"sent"` as "sent", never as admitted. Receipts stay opt-in (`writeReceipts: true`); neither mode is the default.
-- The package is renamed `cultmesh-ts` to `@gamecult/cultmesh-ts` (the repo already scopes `@gamecult/cultcache-ts`), so the unscoped name cannot be claimed by someone else. Import from `@gamecult/cultmesh-ts` and its subpaths; the API is unchanged. Depends on `@gamecult/cultnet-ts`.
 - `asSchemaAlias` is removed from `CultMeshDocumentHandle`, `CultMeshCollectionHandle` and their bound forms. Read the handle by the schema you mean.
 - `CultMeshDocumentCatalog` (`document`, `tryDocument`, `latest`, `replace`, `submitPrediction`, `authoritativeWriter`, `predictionWriter`, `watch`) and `CultMeshCollectionCatalog` (`collection`, `tryCollection`, `latest`, `watchChanges`) take `<TDocument = never, TSchema>` and yield `CultMeshCatalogValue<TDocument, TSchema>`: an explicit type argument wins, a CultCache document definition names its own value type, and a bare schema descriptor yields `unknown`. A value type is no longer inferred from a value or an expected result. The `parse` option is removed from these calls, and a lookup by type answers with that type's handle or none, not an alias of a compatible schema.
-- `createRudpDocumentServer` takes `writeAuthorityTimeoutMs` (default `CULTMESH_RUDP_DOCUMENT_SERVER_DEFAULT_DECIDE_TIMEOUT_MS`, 5000; a value outside 1..2147483647 throws `RangeError`): a write authority whose `decide()` has not settled by then refuses the write like one that throws (`write_not_authorized`, and `onError` hears of it), so a hung authority no longer holds up the session's later frames.
-- `createRudpDocumentServer` refuses every peer put and delete unless it is given a `writeAuthority`. A refused write is answered with the typed `write_not_authorized` naming the record key (the bytes pinned in `error-vectors.json`), and `onDocumentPutRaw` is never called; pass `writeAuthority: new CultMeshGrantAllWrites()` to keep the old accept-everything behaviour. The authority is asked before the put is sized or decoded and before any handler runs, with the canonical schema id and the peer's address (the schema id is resolved to its canonical form first, which is the timing residual below); one that throws, rejects or answers anything but `granted: true` refuses. A frame the server cannot read is judged as the write it looks like (a put when it does not decode at all), so an ungranted peer gets `write_not_authorized` for it too; a granted peer gets `onError` and a typed `message_invalid` refusal (`details.field` is `message`). A put carrying a wrong-typed `shardId` or `shardEpoch` is judged with null shard fields and, once granted, refused with `message_invalid` naming that field. A refusal's record key and reason are clipped (64 and 96 UTF-8 bytes) so the refusal is at most 309 bytes; a `maxPayloadBytes` below that cannot carry it, and the peer then hears nothing (the failure goes to `onError`). Residual: ungranted peers can still distinguish registered from unregistered schemas by timing. A peer `document_delete` now reaches the new `onDocumentDeleteRaw` once granted (without it, a text refusal) instead of the unsupported-request error.
 - Adding a document or collection to a catalog under a schema id or schema name another type already holds is refused with `SchemaConflictError`.
 
 ### Added
 
-- `createRudpDocumentServer` ends a session after `CULTMESH_RUDP_DOCUMENT_SERVER_MAX_CONSECUTIVE_REFUSED_FRAMES` (8) consecutive undecodable frames or consecutive deletes the write authority refuses; fewer are answered and the session is kept. Any decoded frame resets the undecodable run, any decoded non-refused-delete frame resets the delete run. The same cap holds in every runtime.
 - `CultMeshCatalogValue<TDocument, TSchema>`, exported.
 - `documentById` and `tryDocumentById` on `CultMeshDocumentCatalog`, which address one document by its document id when a catalog holds several documents of one type.

 ## RUDP Helpers
 
-`createRudpDocumentServer` refuses every peer put and delete unless given a `writeAuthority` (`new CultMeshGrantAllWrites()` accepts all). The authority is asked before a write's payload is sized or decoded and before any handler runs, and a refusal is the typed `write_not_authorized`. Residual: ungranted peers can still distinguish registered from unregistered schemas by timing.

 ### Added
 
-- `CultNetErrorCode::MessageInvalid` (`message_invalid`), the code for a request that lacks a required field or carries an ill-typed one; a captured-C#-bytes case pins it.
 - The provider half of `gamecult.runtime_presence_health.v2` for Idunn-managed Rust services, in one module that builds and runs on every platform an Idunn driver launches (unix under Idunn's systemd driver, Windows under its host driver). `IdunnRuntimeAuthority::open(target, health_contract, credentials)` reads the runtime bundle, the candidate bind and the write lease from the launch environment Idunn set (no caller supplies a path) and checks every binding Idunn expects (target and health contract, activation bound to Expected, both signing credentials, the write-lease and candidate-bind environment; the candidate bind must equal Expected's route exactly). The credentials' delivery decides the custody the bundle is held to: `IdunnRuntimeCredentials::from_systemd_descriptors` (unix; found by name per sd_listen_fds_with_names(3), `LISTEN_PID` or the `PrivatePIDs` pid-1 rule, root-owned 0400 single-link read-only files, close-on-exec, `LISTEN_*` removed from the environment) carries root custody (bundle directory, `expected.cc`, `activation.cc`, their `.lock` siblings and every parent root-owned, not group- or world-writable, no symlinks, and the same for the write lease), while `from_host_environment` (the host driver's files; the provider identity is opened before the one-shot activation credential is read and removed, and a refusal leaves the credential in place) carries profile custody on every platform (the bundle is a real directory of real files, never a link: std's `is_symlink` refuses symlinks and, on Windows, junctions). No refusal names a path; an unreadable store is reported by its failure kind alone (not decodable, unsupported format, not found, permission denied, I/O error). `IdunnRuntimePresenceSigner` takes the authority by value, owns the reported health (`RuntimePresenceState`, starting Warming; `report_health`), signs validated presence records with `sign` / `sign_at` (returning `SignedRuntimePresence`: record, raw CultNet document and canonical digest), holds Idunn's process write lease through a `ProcessWriteLeaseGuard` (unix only; `try_acquire_write_lease`; the guard holds the lease's `.lock` shared and `require_current` detects replacement; a runtime whose Expected requires a lease is refused at `open` elsewhere with `write_lease_required`), keeps signing Failed, without a lease digest, after the lease is lost, and answers Idunn's route challenge from local authority with `answer_route_observation`. The module owns no network. No wire bytes change: its output passes `authenticate_runtime_presence_claim` and `correlate_runtime_presence_claim`. New unix-only dependencies: `libc`, `fs2`.
 - The launch-contract names both sides of an Idunn launch read: `IDUNN_RUNTIME_BUNDLE_ENVIRONMENT`, `IDUNN_RUNTIME_CANDIDATE_BIND_ENVIRONMENT`, `IDUNN_PROCESS_WRITE_LEASE_ENVIRONMENT`, `IDUNN_ACTIVATION_CREDENTIAL_ENVIRONMENT`, `RUNTIME_PRESENCE_IDENTITY_BINDING` and `RUNTIME_PRESENCE_IDENTITY_FD_NAME`.
 - Version 0.3.0: the unreleased `register` and `CultMeshCdnChunkRef` breaking changes below follow the 0.y.z minor lane.

-- Write receipt, client side (`contracts/cultnet/interop/write-receipt.md`): `cultnet.write_admitted.v0` and `cultnet.error.v1` (v0 plus `messageId`; its closed code set adds `limit_reached`, `CULTNET_ERROR_V1_CODES`) parse and encode, and `CULTNET_WRITE_RECEIPT_MESSAGE_VERSIONS` / `helloAdvertisesWriteReceipts` name the hello capability. `cultnet.error.v0` and its code set are unchanged. `WriteTracker` settles each write as admitted, refused or unconfirmed (windows `RECEIPT_RESULT_WINDOW_MS` 5000 and `LEGACY_RESULT_WINDOW_MS` 500, counted from the send; late answers recorded as `admitted_late` / `refused_late`), and `tools/replay-write-receipt-vectors.mjs` replays the vectors against it (see README, "Write receipt replay runner"). The interop schemas are read from `contracts/cultnet/interop/`.
-- `message_invalid` joins the closed `cultnet.error.v0` code set, with `cultNetMessageInvalidError(field, reason)` (`details.field` names the request field at fault), byte-identical to the C# `ForMessageInvalid`.
-- `cultNetWriteNotAuthorizedError(recordKey, reason?)`: the typed `write_not_authorized` refusal (code and `details.recordKey`), byte-identical to the C# `ForRemoteWriteRefused` vector in `error-vectors.json`. `CultNetDocumentRegistry.canonicalSchemaId(schemaId)` resolves the id a put or delete writes under, for a server's write authority.
-- `cultNetTextError(error)`: the text-only `cultnet.error.v0` refusal, with `routingHint`, `code` and `details` null. The legacy-union error decode uses it, so there is one place that spells the null members.
 - `CultNetRudpSocketTransportServer`: one UDP socket serving many peers, each remote address and port with its own reliable session (`peerConnected`, `frame`, `peerDisconnected` events; `send(peer, ...)` answers on the peer a frame came from). A second client no longer replaces the first; Connects beyond `maxPeers` (default 256) are dropped, and `close()` resolves once every peer's goodbye has left the socket. The shape follows the Rust `CultNetRudpServerHub` and C# `CultNetRudpSocketTransportServer`, and the wire format is unchanged. The optional `peerTimeoutMs` (idle peers ended and told so; default off) exists only in TypeScript. `CultNetRudpSocketTransportConnection` in `server` mode still serves exactly one peer.
 
 - The `cultnet.snapshot_request.v1`, `cultnet.database_subscribe.v1` and `cultnet.snapshot_response_raw.v1` carriers and the selection payload types (`CultNetSelection`, `CultNetRawDocumentHeader`, `CultNetEdge`). `parseCultNetMessage` accepts them (absent members arrive as absent keys; a page carries exactly one of `headers`/`documents`; an empty or blank `schemas`/`keys` entry throws `CultNetSelectionInvalidError` naming its field), and `encodeCultNetMessageForWire` writes the reference's nil-keyed, declaration-ordered map. Judged against bytes the C# reference wrote (`contracts/cultnet/interop/carrier-vectors.cs-written.json`) and the selection vectors C# and Rust wrote. The selection engine (evaluation, cursors, the declaration-dependent door checks) is not ported.
 
 ### Breaking
 
-- The Idunn runtime presence publisher is send-only (`sendPresenceDocument`): it returns `"sent"` once Odin's transport has acknowledged the put and no longer waits up to 500 ms for a success reply, which was never admission. It rejects `IdunnPresenceRefusedError` for a `cultnet.error.v0`, or a `cultnet.error.v1` naming the put or nothing, that arrives by the ack; a refusal after the ack is not awaited, and no other frame, one carrying the put's id included, counts as success.
-- The package is renamed `cultnet-ts` to `@gamecult/cultnet-ts` (the repo already scopes `@gamecult/cultcache-ts`), so the unscoped name cannot be claimed by someone else. Import from `@gamecult/cultnet-ts` and its subpaths; the API is unchanged.
 - `CultNetErrorMessage` carries `routingHint`, `code` and `details` (null when absent), as the reference writes them and `cultnet.error.schema.json` requires; the interface previously dropped them. New `CultNetErrorCode`, `CultNetErrorDetails` and `CultNetShardRoutingHint` types.
 
 - `CultMeshCdnChunkRef` carries `id` (slot 4), the reference's element id. `encodeManifest` writes five-slot chunk references and `packContent` sets the decimal offset as the id, as the reference does; a manifest written before ids reads `""` and is rewritten with the slot. Content vectors regenerated from the reference.

-## Write receipt replay runner
-
-`WriteTracker` is the client half of `contracts/cultnet/interop/write-receipt.md`: a pure state machine on an abstract
-clock that owns one decision, how each sent write settles. `tools/replay-write-receipt-vectors.mjs` replays
-`write-receipt-vectors.json` against it (build first, then `node tools/replay-write-receipt-vectors.mjs`): it prints
-`PASS`/`FAIL` per case and exits nonzero on any failure. Rust and C# port the same runner by implementing this interface
-and replaying the same file.
-
-Tracker interface (times are integer milliseconds on the vector's clock; the constructor takes the window):
-
-| Call | Meaning |
-| --- | --- |
-| `new WriteTracker({ windowMs, onSettle })` | `windowMs` = 5000 when the server's hello lists both `cultnet.write_admitted.v0` and `cultnet.error.v1`, else 500. `onSettle(id, settlement)` fires once per write. |
-| `send(id, atMs)` | A write with that `messageId` was sent. Its window runs from here, not from any transport ack. |
-| `frame(message, atMs)` | A decoded frame arrived. `write_admitted` and `error.v1` settle the write they name; `error.v0`, or `error.v1` with nil `messageId`, refuses a write only when exactly one is unanswered; an id not in flight settles nothing. |
-| `tick(atMs)` | Advance the clock. Every unanswered write with `atMs - sentAt >= windowMs` settles `unconfirmed(window_elapsed)`. `send`, `frame` and `sessionEnd` tick first. |
-| `sessionEnd(atMs)` | Every unanswered write settles `unconfirmed(session_ended)`. |
-| `state(id)` | `pending`, or the settlement plus `recorded`: `admitted_late` / `refused_late`, set by the first answer that arrives after `unconfirmed`. A settlement never changes. |
-
-Runner, per case in `scenarios.cases` (the transport ack is not an input: delivery is not an answer):
-
-1. The fake server states its capability the only way a real one does, in a hello (`server: "receipt"` lists both frames, `"legacy"` lists none); the window comes from that hello and must equal `constants[case.window]`.
-2. Events run in `atMs` order: `send` -> `send(id)`, `frame` -> encode the frame to MessagePack, decode and validate it as the client would, then `frame(message)`, `tick` -> `tick`, `sessionEnd` -> `sessionEnd`, `transportAck` -> nothing.
-3. For each id in `expect`, the settlement given to the caller has the expected `outcome` (and `code` or `reason` when given), `state(id).recorded` equals the expected `recorded` (absent when absent), and nothing settled twice or outside `expect`.
-
-The runner also decodes each `wire[].messagePackHex` and compares the fields and the re-encoded bytes to the vector, and requires every `schemaInvalid[]` frame to be refused by the decoder. `dedupe.cases` and `contentHash` are server vectors and not replayed here.
