 # Auto detect text files and perform LF normalization

-# Shell scripts keep LF in the working tree as well as in the index. Left to
-# `text=auto`, a Windows clone writes them with carriage returns, and the
-# documented Linux path then dies inside the container in under a second: the
-# shebang reads as the interpreter `bash\r`, which does not exist. Nothing about
-# that failure names line endings, and the same clone builds and tests fine
-# everywhere else, so it reads as a broken image rather than a broken checkout.
-#
-# A clone checked out before this rule keeps its carriage returns, because the
-# blob is unchanged and git has no reason to rewrite the file. The one-line
-# repair is in native/GameCult.Mesh.Quic.Native/README.md, beside the container
-# path it unblocks.

Both runtimes resolve a schema alias the same one way: strip a trailing .vN and compare the remainder against the descriptor's declared SchemaName (CultNetSchemaAliasMatching.Matches(candidate, CultDocumentDescriptor), src/GameCult.Networking/CultNetDatabase.cs:74-87; cultnet_rs::selection::schema_alias::matches ports it name-for-name and deletes the hash-stripping overload it used to carry). nameAlias is <SchemaName>.v9 and resolves through both runtimes under that one rule. hashAlias is <schemaId>.v1 and is refused as unmatched by both - it is not a wire form either runtime's production call sites ever produce or accept, and it is kept in the fixture specifically to pin that neither runtime resolves it.",

This fixture used to also carry a `targetSchema` per reference; it was never anything but documentation - SelectionParityVectorTests.BuildDocument and cultnet-rs's build_row both read only targetKey to construct the edge - and it is removed rather than kept as a field the wire does not have.

-# Semantic Versioning Policy
-
-Operator ruling, 2026-09-17: **semantic versioning is policy** for every
-package CultLib publishes, strictly. A release that removes or changes public
-surface incompatibly is a major bump, full stop — not a judgment call left to
-the person cutting the release.
-
-This document says what "breaking" means for each kind of surface this repo
-actually ships, and how a release is checked against it. See
-`docs/nuget-packaging.md` for how the managed/Unity packaging mechanics work;
-this document is the versioning contract those mechanics must satisfy.
-
-## The scar
-
-`org.gamecult.cultlib` 1.0.60 removed `CultInspectorAssetPath` — public API —
-and shipped as a patch bump. Its own changelog entry is titled "Breaking"; the
-version number said otherwise. A reviewer relying on the number alone would
-have missed it. This is recorded as history, not fixed by renumbering: `1.0.60`
-stays `1.0.60`. This policy, and the check below, exist so the next one is
-caught before it ships instead of written up afterward.
-
-## Packages in scope
-
-| Package | Kind | Tag prefix | Published by |
-| --- | --- | --- | --- |
-| `org.gamecult.cultlib` | Unity UPM | `cultlib-unity` | `scripts/build-unity-package.ps1`, consumed by git tag |
-| `org.gamecult.caching.unity` | Unity UPM | `caching-unity` | tagged directly (no build script; see "Coverage gaps") |
-| `org.gamecult.cultmath` | Unity UPM | `cultmath-unity` | `packages/cultmath/scripts/build-unity-package.ps1`, consumed by git tag |
-| `@gamecult/cultcache-ts` | npm | `cultcache-ts` | `.github/workflows/publish-packages.yml` |
-| `cultcache-py` | PyPI | `cultcache-py` | `.github/workflows/publish-packages.yml` |
-| `cultnet-py` | PyPI | `cultnet-py` | `.github/workflows/publish-packages.yml` |
-| `cultmesh-py` | PyPI | `cultmesh-py` | `.github/workflows/publish-packages.yml` |
-
-Rust crates are consumed as pinned git revisions (see `publish-packages.yml`'s
-own header comment) and are out of scope for tagged-release semver policing;
-a `Cargo.toml` version still exists and should follow this policy by
-convention, but nothing in this repo checks it mechanically today.
-
-Tag naming stays `<package>-v<version>` for every package above, matching the
-prefixes already in use.
-
-## What counts as breaking
-
-Semver's ordinary rule — additive is minor or patch, anything a consumer's
-existing code or data can no longer rely on is major — applies per surface as
-follows.
-
-### Managed public API (`org.gamecult.cultlib`, NuGet packages, `cultmath`)
-
-Breaking: removing or renaming a public type/member, changing a public
-member's signature or observable behavior in an incompatible way, tightening
-a public contract (new required parameter, narrowed accepted input),
-or moving a type across assemblies/namespaces without a compatible forwarder.
-
-Not breaking: adding a new public member, type, or overload; widening an
-accepted type; deprecating (marking obsolete) without removing.
-
-### Unity package inspector attributes (`org.gamecult.cultlib`,
-`org.gamecult.caching.unity`)
-
-These ship as ordinary public API by the rule above, but get their own
-callout because they are easy to mistake for "just editor tooling": an
-attribute class, its constructor shape, and the serialized value shape it
-reads/writes are all public surface a consumer's `[CultInspectorX(...)]`
-usage and serialized scene/prefab data depend on. Removing or renaming an
-attribute, or changing what it expects a annotated member's persisted value to
-look like (as `CultInspectorAssetPath` to `CultInspectorAssetGuid` did in
-1.0.60) is breaking.
-
-### Persisted wire format / store compatibility (CultCache)
-
-Governed by `src/GameCult.Caching/Contracts/cultcache-schema-compatibility.md`
-and `cultcache-persistence-format.md` — read those for the authoritative
-rules. In semver terms: anything those documents classify as **hard
-rejection** (type change, reference/value change, one-vs-many change, target
-schema change, name/index lookup semantics change, a persisted schema with no
-compatible local candidate) is breaking for any package that reads or writes
-the format. Anything classified as **soft-migratable drift** (compatible
-schema id drift, an ignorable missing slot, a defaultable missing slot) is not
-breaking on its own, but changing what counts as soft-migratable — loosening
-or tightening the drift rules themselves — is breaking for whichever package
-owns that classification logic.
-
-### CultNet protocol surface
-
-Breaking: a wire-incompatible change to a CultNet message, frame, or
-handshake shape; removing or repurposing a message type or field that another
-runtime's implementation depends on; changing routing, authority, or trust
-semantics such that a peer built against the previous protocol version
-misbehaves rather than cleanly failing. Additive, backward-compatible framing
-changes (a new optional field a receiver may ignore) are not breaking.
-
-### Native bridge exported functions (`GameCult.Mesh.Quic.Native`)
-
-Breaking: removing or changing the signature/ABI of a `CULTMESH_API`
-(`extern "C"`) exported function, or changing an exported function's
-behavior such that the existing managed P/Invoke caller (`GameCult.Mesh.Quic.Native`'s
-C# side) or Rust caller (`cultmath-core`'s equivalent `#[no_mangle] extern "C"`
-surface) no longer gets what it asked for. Swapping the underlying TLS/QUIC
-implementation (as 1.0.60 did, Schannel to OpenSSL MsQuic) is not breaking
-*by itself* as long as the exported v1 functions keep their signatures and
-behavior — 1.0.60's actual breaking change was the inspector attribute
-removal, not the bridge swap, and its changelog correctly filed the bridge
-swap under "Changed" rather than "Breaking".
-
-## Pre-1.0 packages
-
-A package at `0.y.z` (currently `org.gamecult.cultmath`, at `0.2.x`) uses the
-standard pre-1.0 convention: `MAJOR` stays `0` during initial development, so
-`MINOR` carries what `MAJOR` means once the package reaches `1.0.0`. Concretely:
-
-- a breaking change bumps `MINOR` (and resets `PATCH` to `0`);
-- a non-breaking change bumps `PATCH`.
-
-Leaving `0.y.z` for `1.0.0` is a deliberate, separate decision (the API is now
-considered stable), not something the checker infers on its own.
-
-## What a release changelog entry must contain
-
-Every published package keeps a `CHANGELOG.md` beside its manifest
-(`unity/org.gamecult.cultlib/CHANGELOG.md` and
-`src/GameCult.Unity/Assets/Caching/CHANGELOG.md` are the existing precedent).
-Each release adds a `## [<version>]` section containing:
-
-- a category subsection per change (`### Added`, `### Changed`, `### Fixed`,
-  etc., following Keep a Changelog style);
-- **`### Breaking`** — this exact heading, this exact spelling — for any
-  change that meets the "what counts as breaking" rules above. This heading
-  is not decorative: the CI check below greps for it by name.
-- enough detail that a consumer can tell what to change, in the style of the
-  1.0.60 entry (name the removed/changed symbol and its replacement).
-
-A version with no changelog entry at all fails the check below, the same as
-a mislabelled one — an undocumented release is not a smaller sin than a
-mislabelled one.
-
-## Enforcement
-
-`scripts/check-changelog-semver.mjs` is the mechanical check. Given a
-package name, its `CHANGELOG.md` path, the version being released, and a git
-tag prefix, it:
-
-1. resolves the previous published version from the highest existing
-   `<prefix>-v*` tag older than the version being released (or treats the
-   release as a package's first if none exists);
-2. requires a `## [<version>]` changelog entry to exist at all;
-3. classifies the version bump (major/minor/patch) against the previous
-   version, refusing anything that is not exactly the next version in some
-   lane — a skip, a reversal, or a repeat are all refused, not just wrong
-   bump sizes;
-4. if the changelog entry has a `### Breaking` section, requires the bump to
-   be at least major (or, pre-1.0, at least minor);
-5. fails loudly, naming the package, the previous and new version, and (when
-   relevant) the changelog heading that triggered the requirement.
-
-Run it directly: `node scripts/check-changelog-semver.mjs --package <name>
---changelog <path> --version <x.y.z> --tag-prefix <prefix>`. Its own tests
-live in `scripts/check-changelog-semver.test.mjs` (`node --test
-scripts/check-changelog-semver.test.mjs`).
-
-It is wired into:
-
-- `.github/workflows/publish-packages.yml`, right after each job's existing
-  "tag matches manifest version" check, for `cultcache-ts`, `cultcache-py`,
-  `cultnet-py`, and `cultmesh-py`;
-- `scripts/build-unity-package.ps1`, for `org.gamecult.cultlib`;
-- `packages/cultmath/scripts/build-unity-package.ps1`, for
-  `org.gamecult.cultmath`;
-- `scripts/verify-caching-unity-release.ps1`, for `org.gamecult.caching.unity`.
-
-### Coverage gaps
-
-`publish-packages.yml` only triggers on `cultcache-ts-v*`, `cultcache-py-v*`,
-`cultnet-py-v*`, and `cultmesh-py-v*` tag pushes — it does not build or gate
-the Unity UPM packages at all; those are consumed directly by git tag
-(`unity/org.gamecult.cultlib`, `packages/cultmath/unity/org.gamecult.cultmath`,
-`src/GameCult.Unity/Assets/Caching`), so a workflow trigger on their tags
-cannot be added to that file without also giving it a reason to check out and
-build Unity content it currently has no job for. The check is instead wired
-into the scripts that already run at Unity-package release time:
-`build-unity-package.ps1` and `packages/cultmath/scripts/build-unity-package.ps1`
-already verify version consistency between the built assembly and
-`package.json`, so the semver check runs alongside that as one more release
-gate. `org.gamecult.caching.unity` has no build script at all today — it is
-pure C# source tagged directly with no compile step — so
-`scripts/verify-caching-unity-release.ps1` exists solely to run this check
-before that package is tagged; it is not a build script and does not become
-one.
-
-None of this is enforced by a git hook or branch protection rule: it runs
-when someone remembers to run the Unity release scripts, the same way the
-existing assembly-version check does. A tag pushed by hand without running
-the release script bypasses both checks equally; closing that gap is a CI
-trigger on tag push for the Unity packages, not something this change adds.
-
-Rust crates (consumed as pinned git revisions, not tagged releases in the
-usual sense) and the CultNet protocol surface itself (no automated wire
-compatibility test currently gates a release) are policy by convention only —
-described above, not mechanically checked. Extending the checker to a Rust
-crate's `Cargo.toml`/`CHANGELOG.md` or to an automated CultNet interop
-compatibility gate is future work, not part of this change.
-
-`@gamecult/cultcache-ts`, `cultcache-py`, `cultnet-py`, `cultmesh-py`, and
-`org.gamecult.cultmath` currently have **no `CHANGELOG.md` file at all**. This
-is a real, pre-existing gap, not something introduced by this policy: their
-next tagged release will fail the new check for exactly that reason ("no
-changelog entry for version X") until each package's `CHANGELOG.md` exists.
-That failure is intended — a release with no changelog is not a smaller
-problem than a mislabelled one — but it does mean the very next release of
-any of these five packages needs a `CHANGELOG.md` created first. Backfilling
-changelog content for their past releases is not part of this change: it
-would mean inventing release-note prose for history this pass has no
-first-hand knowledge of, which is worse than leaving the gap named.

-# TypeScript QUIC Realtime Plane Target
-
-Date: 2026-09-16
-
-Status: target accepted by the operator (2026-09-16), ready for Eureka. No cut
-map exists yet. When the pipeline starts, Imagination maps the cut into
-`docs/typescript-quic-realtime-cut.md` against `main` at `a0813c6` or later.
-
-The TypeScript runtime gains the CultMesh QUIC realtime state plane that the C#
-runtime already has: a provider that serves frames and a consumer that receives
-them, byte-compatible with `GameCult.Mesh.Quic` and the native MsQuic connector
-the Unity package ships. This document states the end state and the invariants
-that constrain getting there.
-
-Operator ruling, 2026-09-16, on providing QUIC for a Node service: "Option 2 all
-the way, this is what CultLib is supposed to be, we're not half assing it." A
-separate .NET provider process and a WebSocket shortcut were both rejected.
-
-## Why now
-
-The first consumer is StreamPixels. Its service (Node 24, TypeScript, on
-Yggdrasil) must publish realtime state to a Unity overlay running on a
-streamer's machine. The overlay is a receive-only client using the Unity
-package's `CultMeshNativeQuicRealtimeTransportConnector`. Today no TypeScript
-path exists:
-
-- Node v24.15.0 has no `node:quic`, with or without `--experimental-quic`.
-- `packages/cultmesh-ts` and `packages/cultnet-ts` contain no QUIC code.
-- `GameCult.Mesh.Quic` (.NET 10, `System.Net.Quic`) is the only QUIC provider.
-- The C# TCP control and content connectors are plaintext and restricted to
-  loopback (`src/GameCult.Mesh/docs/transport-planes.md`, "Security and release
-  gate"), so they cannot carry the overlay's remote session either.
-
-## This touches the foundation
-
-- **Wire parity is an invariant.** The C# codec is the reference:
-  `src/GameCult.Mesh/CultMeshRealtimeWireProtocol.cs`. The TypeScript runtime
-  must produce and accept identical bytes:
-  - ALPN `cultmesh-state-v1`; connection close code `0x43554c54`, stream abort
-    code `0x53544154`; reliable stream type `1`, latest-only stream type `2`.
-  - Frame: magic `0x31545343`, then a 37-byte little-endian fixed header
-    (delivery byte, producer epoch i64, sequence i64, channel/schema/body id
-    lengths u16, payload length i32, header size i32 = 37, wire version u16 =
-    1), then UTF-8 channel id, schema id, body id, then payload.
-  - Limits: payload at most 64 MiB; each identity at most 65,535 UTF-8 bytes;
-    decode rejects wrong magic, unknown version, out-of-range delivery, and any
-    length that does not sum exactly.
-- **Delivery semantics are an invariant**
-  (`src/GameCult.Mesh.Quic/README.md`, `CultMeshRealtimeTransports.cs`):
-  - `ReliableOrdered`: one persistent ordered stream; broadcast is
-    completion-bearing.
-  - `LatestOnly`: independent streams; at most one pending frame per
-    `(channel, body)`, replaced by a newer `(producer epoch, sequence)`
-    generation; a keyed coalescing outbox per physical peer, so a slow or
-    departed consumer never backpressures the producer.
-  - `Unreliable`: fails closed until datagrams are exposed, matching the managed
-    C# adapter.
-- **Trust is an invariant.** No remote session comes online without the chain
-  in `transport-planes.md`: an Odin-signed `CultMeshRouteCertificate` (Verse,
-  authority runtime, protocol set, endpoint, generation, validity, provider
-  P-256 key) checked against consumer-pinned Odin roots, TLS 1.3, and the
-  endpoint certificate bound to that route, including the
-  `cultmesh-state+quic://host:port?cert-sha256=<uppercase SHA-256>` pin.
-  Signatures are ECDSA P-256 over SHA-256 with P1363 `r || s` encoding and the
-  length-prefixed canonical transcript. Unsigned traffic exists only under an
-  explicit `LocalDevelopment` policy on loopback.
-- **One implementation of TypeScript route verification.** `cultmesh-browser`
-  already verifies Odin route certificates and provider nonce possession with
-  WebCrypto (`packages/cultmesh-browser/src/index.ts`, `verifyAuthorityRoute`,
-  `canonicalRoute`, `canonicalSession`, `verifyP256`). The Node QUIC path must
-  reuse that owner, not grow a second verifier.
-- **The realtime plane carries state frames only.** Schemas, commands,
-  receipts, manifests, and immutable content do not travel through it
-  (`ICultMeshRealtimeTransport` doc comment). RUDP is never installed
-  implicitly in its place.
-- **Existing consumers survive.** The StreamPixels service already imports
-  `cultcache-ts`, `cultnet-ts`, and `cultmesh-ts` (`verse-state.ts`,
-  `idunn-rudp-health.ts`) for Odin advertisement and Idunn health over RUDP.
-  Imagination audits every other TypeScript consumer across `F:\Projects`
-  before sizing the cut.
-
-## Target state
-
-- `cultmesh-ts` exposes a QUIC realtime provider and a QUIC realtime consumer
-  with the same ergonomic shape as the C# `CultMeshQuicRealtimeServer`
-  (listen, broadcast with an explicit delivery mode) and
-  `ICultMeshRealtimeTransportConnector` (connect by advertised candidate,
-  receive frames), under the branded `CultMesh` entrypoint.
-- QUIC comes from native MsQuic bindings owned by CultLib, not from a Node
-  polyfill or a third-party QUIC stack with different semantics. How the binding
-  is built and shipped is the means (Imagination probes it); what it must
-  deliver is TLS 1.3, ALPN, independent unidirectional or bidirectional streams,
-  certificate validation with a caller hook, and clean close and abort codes.
-- Frame encoding and decoding exist once in TypeScript and are tested against
-  bytes produced by the C# codec.
-- Application code never picks endpoints, ranks routes, or writes reconnect
-  loops; `CultMeshSessionManager`-equivalent route selection owns that, as in C#.
-- The build produces binaries for the hosts that run them: Windows x64 for
-  local development, and Linux x64 for Yggdrasil, built on Linux or the deploy
-  path's builder, not cross-compiled on Starfire.
-
-## Not in this migration
-
-One foundation per pipeline. These are separate, named pipelines or consumer
-work:
-
-- **TypeScript content plane** (a provider in `cultmesh-ts`, a verifying HTTPS
-  reader in `cultmesh-browser`) for exported character artifacts. HTTPS content
-  transport and single-host trust on Yggdrasil were already ruled.
-- **Authenticated remote control plane** (TLS on the TCP schema and content
-  connectors). See Q1.
-- **Browser QUIC** (WebTransport). Browsers keep the verified WebSocket path.
-- **Python, Rust, and Kotlin QUIC.** The parity scope is role-scoped; this
-  migration claims TypeScript and C# only.
-- **StreamPixels integration** (service publication, overlay subscription, and
-  the catalog and scene-intent schemas) is consumer work in StreamPixels after a
-  released `cultmesh-ts` exists.
-
-## Verification the cut must reach
-
-- Golden frame bytes from the C# codec decode in TypeScript, and TypeScript
-  encodings decode in C#, for every delivery mode and at the length limits.
-  Malformed inputs are rejected identically.
-- Separate processes, both directions: a TypeScript provider to the C# native
-  connector (the one Unity uses) and to the managed connector, and a C# managed
-  provider to the TypeScript consumer. Extend the existing parity harnesses
-  (`CULTMESH_NATIVE_EXTERNAL_ENDPOINT`, `packages/cultnet-ts/test/interop`) rather
-  than adding a parallel one.
-- `LatestOnly` coalescing: a stalled consumer does not delay the producer, and
-  the consumer converges on the terminal generation.
-- Trust negatives: an expired or unsigned route, the wrong Odin root, a
-  mismatched `cert-sha256` pin, and a replayed nonce are each refused, with a
-  mutation per rule.
-- The Linux x64 binary runs on the Yggdrasil deploy path, verified on that host.
-
-## Rulings (operator, 2026-09-16)
-
-The operator accepted every recommendation below ("You got it"). Each question
-is kept with its options as the record of what was decided against.
-
-- **Q1. Which remote plane carries the overlay's non-frame data?** The realtime
-  plane forbids schemas, commands, and content, and the TCP planes are
-  loopback-only. A: publish her character, the subathon window, and scene
-  intents as QUIC state frames with their CultCache schema id and payload, and
-  ship the costume catalog as a versioned immutable artifact on the HTTPS
-  content plane; the overlay sends no commands, so it needs no remote control
-  plane. B: add TLS to the TCP schema and content connectors as its own
-  pipeline first. **Recommended: A.** It needs no new plane for M1, matches a
-  receive-only client, and leaves TLS TCP to the first consumer that sends
-  commands.
-- **Q2. Where does shared TypeScript route verification live?** It is inside
-  `cultmesh-browser` today, and `cultmesh-ts` is Node-only. A: move it to a
-  browser-safe shared module that both import (for example beside
-  `cultnet-ts/contracts`). B: have `cultmesh-ts` depend on `cultmesh-browser`.
-  **Recommended: A**, so neither transport package owns the other's trust.
-- **Q3. Which platforms must the native binding support at release?**
-  **Recommended: Windows x64 and Linux x64 only**, the two hosts that run it
-  today.
-- **Q4. Are QUIC datagrams (`Unreliable`) in scope?** **Recommended: no.** Fail
-  closed like the managed C# adapter; no consumer needs them.

 # GameCult.Mesh.Quic.Native
 
-One MsQuic body for every CultMesh host that is not .NET: two roles (provider
-and consumer), two platforms (Windows x64 and Linux x64), and no callbacks
-across the host boundary.
+This Windows desktop bridge keeps MsQuic's callback-heavy C API below the
+managed runtime boundary. It accepts a discovery-authorized SHA-256 certificate
+pin, negotiates `cultmesh-state-v1`, and emits complete CultMesh realtime frame
+payloads. It owns transport only; frame meaning remains in `GameCult.Mesh`.
 
-The bridge owns MsQuic registration, configuration, listener, connection and
-stream handles, TLS credential loading, the `cultmesh-state-v1` ALPN, the
-1-byte-kind plus 4-byte-LE-length QUIC stream framing, and one event queue per
-runtime. It owns transport and nothing else: it never decodes a CultMesh frame,
-never decides delivery semantics, never coalesces, never reconnects, and in the
-v2 path never decides whether to trust a certificate. Frame meaning stays in
-`GameCult.Mesh` and in the TypeScript codec; trust stays with the host.
-
-## No host callbacks
-
-Every crossing is the host calling in, including the one blocking wait. MsQuic's
-worker threads only ever push onto the queue and wake that wait, so no host
-runtime is called from a thread it does not own. That is what lets one binary
-serve a Node process through FFI and a Unity player through P/Invoke without
-either one's threading rules leaking into the other.
-
-It is also why nothing here includes a Node header, a Unity header, or a
-JavaScript engine: the bridge does not know what is on the other side.
-
-## Two ABIs
-
-**v2** is the runtime-neutral queue API, and the one new hosts should use. It is
-stated once, in [`include/cultmesh_quic_native.h`](include/cultmesh_quic_native.h):
-the 64-byte event struct with its field order and asserted offsets, the thirteen
-exports with their signatures, the id and return-code conventions, the object
-lifetime rules and the threading rules. That file is the contract. This README
-does not restate it, and where the two ever disagree the header is right.
-
-A host that can include it should. A host that cannot — koffi, Unity's
-P/Invoke — declares the same thing in its own FFI and is checked against the
-header by a test rather than by eye.
-
-Two things worth reading before writing a host, because they are easy to get
-wrong from the outside:
-
-- **Return codes are negative on a bad call, on every platform.** `-1` is a bad
-  call, `-2` a rejected argument, `<= -1000` a MsQuic refusal. `QUIC_STATUS`
-  itself is not portable — a negative HRESULT on Windows, a positive errno on
-  POSIX — so it never reaches a host; `cultmesh_quic_last_status` hands over the
-  raw value for diagnostics and nothing else.
-- **`cultmesh_quic_runtime_close` quiesces.** It marks the runtime closing, wakes
-  every blocked `cultmesh_quic_next_event`, and waits for every in-flight call to
-  return before it frees anything. No host call may begin after it starts.
-
-A client connection defers certificate validation: the bridge indicates the
-certificate, emits event 3 carrying the DER, and answers MsQuic only when the
-host calls `cultmesh_quic_connection_certificate_complete`. If the host never
-answers, MsQuic's 10-second handshake timeout closes the connection and event 4
-reports it. Providers load their certificate as PKCS12; the advertised
-`cert-sha256` pin is computed by the host from that same PKCS12, not here.
-
-**v1** is the five exports the shipped Unity package imports by name
-(`cultmesh_quic_open`, `_state`, `_poll`, `_error`, `_close`). They are Windows
-only, matching `CultMeshNativeQuicRealtimeTransport.CanConnect`, and are
-implemented on top of a private v2 runtime holding one connection. They decide
-nothing the v2 path does not, with one exception: a v1 connection carries a
-SHA-256 pin that is compared here, in C, because that is the contract the
-managed connector was built against. A v2 connection never carries one.
-
-## Building
-
-Windows x64, from the repo root:
-
-    powershell -File scripts/build-quic-native.ps1
-
-MsQuic comes from `Microsoft.Native.Quic.MsQuic.OpenSSL` 2.5.9, pinned twice: the
-NuGet zip by digest and size, and the `msquic.dll` inside it by digest and size,
-because the archive is what the download is checked against and the DLL is what
-actually ships beside the bridge. The OpenSSL flavour rather than Schannel
-because Schannel's MsQuic refuses `QUIC_CREDENTIAL_TYPE_CERTIFICATE_PKCS12`,
-which is the only credential type a provider has on both platforms.
-
-The build uses MSVC with `/Brepro` so that a build reproduces itself: the link
-timestamps are dropped, and building the same source twice gives the same bytes.
-It links the CRT statically (`/MT`), because a Node or Unity host without the
-Visual C++ redistributable cannot load a DLL that imports `vcruntime140.dll`,
-and the failure it reports names no missing runtime; the bridge carries its own.
-
-The committed Unity plugin
-(`unity/org.gamecult.cultlib/Runtime/Plugins/x86_64/gamecult_mesh_quic_native.dll`)
-is this build: 302,080 bytes, `/MT`, OpenSSL MsQuic, no CRT import. It replaced
-an older 40,448-byte build — before `/MT` and before the move off Schannel,
-still importing `VCRUNTIME140.dll` and `MSVCP140.dll` — at the CultLib 1.0.60 /
-Studio 1.4.0 release.
-
-Linux x64, on a Debian 13 host:
-
-    scripts/build-quic-native.sh
-
-MsQuic comes from Microsoft's Debian 13 pool as a pinned `.deb`, and the POSIX
-headers from the msquic source tree at the matching tag; all four downloads are
-verified by SHA-256. The bridge is linked with `-fvisibility=hidden` so only the
-v2 exports leave the `.so`, and with `RPATH $ORIGIN` so the `libmsquic.so.2`
-shipped beside it resolves without being installed system-wide.
-
-A Linux host still needs MsQuic's own runtime dependencies present:
-`libssl3t64`, `libnuma1`, `libxdp1`, `libnl-route-3-200`.
-
-The development loop for it is one committed image,
-[`scripts/quic-native-linux-dev.Dockerfile`](../../scripts/quic-native-linux-dev.Dockerfile),
-pinned to the same `debian:13` digest the release workflow builds in. It carries
-the toolchain, MsQuic's runtime dependencies, `setarch`, and Node, because the
-mutation harness that drives the runtime-lifetime scenarios is a Node script and
-a container that cannot run it cannot check the bridge it just built:
-
-    docker build -t cultlib-quic-native-dev -f scripts/quic-native-linux-dev.Dockerfile scripts
-    docker run --rm --security-opt seccomp=unconfined -v "${PWD}:/src" -w /src cultlib-quic-native-dev bash -lc "scripts/build-quic-native.sh && node scripts/mutate-cultmesh.mjs native"
-
-Both lines are run from the repository root, and the mount is that root wherever
-it is: `${PWD}` in PowerShell, `$(pwd)` in a POSIX shell. The second is one line
-because the shell it is offered to is not decided here; a continuation would have
-to pick one, and a backtick pasted into a POSIX shell is not a continuation.
-
-A Windows clone made before `.gitattributes` kept shell scripts at LF still has
-`scripts/build-quic-native.sh` with carriage returns, and pulling does not fix
-it: the script's content did not change, so git neither rewrites it nor reports
-it modified. The container then dies at once on the interpreter `bash\r`. From
-the repository root, in either shell, this checks the script out again under the
-current attributes:
-
-    git rm --cached -q scripts/build-quic-native.sh; git checkout HEAD -- scripts/build-quic-native.sh
-
-`--security-opt seccomp=unconfined` is load-bearing, not caution. The
-ThreadSanitizer configuration needs the process's address space where it expects
-it, so `scripts/mutate-cultmesh.mjs` re-executes those runs under `setarch -R`,
-which asks the kernel for `personality(ADDR_NO_RANDOMIZE)`. Docker's default
-seccomp profile denies that call. Without it ThreadSanitizer dies before `main`
-with "unexpected memory mapping" — a configuration that never starts, which a
-mutation harness would otherwise read as every mutant being killed. The harness
-stops with that diagnosis rather than reporting kills it did not earn.
-
-The win32-x64 half of the harness needs the checkout somewhere short — near a
-drive root rather than under a deep temporary directory. MSVC builds the bridge
-and its scenario runner through MSBuild, whose file tracker gives out on long
-paths, and the build then fails for every mutant including the no-op control.
-The harness stops on a red control rather than reporting a table of kills, so
-the failure is loud, but it names MSBuild and not the path.
-
-Where an artifact was built is part of what it is. The Linux binary is linked
-against Debian 13's glibc, so a build from anywhere else is a different artifact
-whatever the file name says.
+The build consumes Microsoft's pinned
+`Microsoft.Native.Quic.MsQuic.Schannel` package. It does not contain
+Aetheria-specific code.

- * (`QUIC_STATUS_USER_CANCELED` and `QUIC_STATUS_FILE_NOT_FOUND` are both -1002
- * on Windows). Switching on a particular code is therefore not portable and not
- * a reliable identification of the failure. Report it, log it, and read

- *
- * The bridge's objects are shared-owned. The runtime's maps hold one reference
- * each; an export that names an id takes its own reference under the lock and
- * holds it for the whole MsQuic call, so an object cannot be freed under a host
- * thread that is using it. MsQuic's worker, on shutdown-complete, removes the
- * map entry and drops the map's reference only — it never frees an object a host
- * call is inside.
- *
- * The MsQuic handle follows the object: it is closed exactly once, by whichever
- * holder drops the last reference (or by `cultmesh_quic_runtime_close`), under a
- * one-shot exchange guard. A handle is therefore valid for as long as any holder
- * has a reference to its object, which is the property the host thread needs. A
- * stream holds a reference to its connection, so stream handles are always
- * closed before the connection handle they belong to.
- *
- * `cultmesh_quic_runtime_close` quiesces before it tears anything down. It marks
- * the runtime closing, wakes every blocked `cultmesh_quic_next_event`, and waits
- * for every in-flight export to return before it closes a handle or frees a
- * byte. No host call may begin after `cultmesh_quic_runtime_close` starts. That
- * ordering is the host's, and it is a prohibition rather than a race the bridge
- * arbitrates: once the close returns, the handle names freed memory, and a call
- * made with it has nothing left to refuse it. A call that races the start of the
- * close, while it is still running, is refused with -1 and touches nothing; that
- * narrows one mis-ordering and does not make the prohibition optional.

-// Scenario runner for the bridge's runtime lifetime rules.
-//
-// This is the one part of the bridge a host cannot check by reading: whether
-// `cultmesh_quic_runtime_close` is safe against host threads that are inside the
-// library when it starts. Everything here drives that path and nothing else. It
-// opens a runtime, parks pollers in `cultmesh_quic_next_event`, closes the
-// runtime underneath them, and asserts what the header promises: every parked
-// poller returns, and none of them touches the runtime after it is gone.
-//
-// It consumes the bridge through include/cultmesh_quic_native.h — the same
-// contract a host has — and nothing else. No MsQuic header, no internals.
-//
-// The failures it exists to catch are not visible in the return values, because
-// a use-after-free is not an error code. Two things make them visible instead:
-// a sanitizer build (ThreadSanitizer for the notify/destroy race, AddressSanitizer
-// for the freed-runtime dereference), and `CULTMESH_QUIC_DEBUG_ASSERTS`, which
-// makes the bridge state the quiesce invariant itself rather than leaving it to
-// be caught by an unlucky thread schedule.
-//
-//   cultmesh_quic_native_tests closerace [iterations] [pollers]
-//   cultmesh_quic_native_tests holdclose [iterations] [pollers]
-//   cultmesh_quic_native_tests polltimeout [iterations]
-//   cultmesh_quic_native_tests latecall [iterations]
-//   cultmesh_quic_native_tests holdtimeout [iterations]
-//
-// `closerace` hunts the race: many pollers, many iterations, and whatever the
-// schedule gives. `holdclose` takes the guessing out of it — the bridge's
-// development seam (section 7 of the header) holds the pollers inside the
-// library until this scenario releases them, and reports how many host calls the
-// bridge actually counted, so the scenario asserts the quiesce instead of
-// assuming its own fixture worked. It needs CULTMESH_QUIC_DEBUG_ASSERTS.
-//
-// In both of those the wait is ended by the close, so the host's timeout governs
-// nothing either of them can see, and a bridge waiting on a constant of its own
-// passes both. `polltimeout` is the one that lets the timeout govern the return
-// and measures it. `latecall` covers the other half of section 4: a call that
-// races the start of a close is refused rather than counted behind its wait.
-// `holdtimeout` covers the seam's own rule, which nothing else is in a position
-// to see: the hold parks a call the wait woke and not one whose own timeout
-// expired, so the quiesce the hold scenarios assert is the bridge's doing and
-// not the fixture's.
-//
-// Exit code 0 means every assertion held. Anything else, including a sanitizer
-// abort or the bridge's own assertion, is a failure. Under ThreadSanitizer run
-// it with `TSAN_OPTIONS=halt_on_error=1`, or a reported race leaves the exit
-// code to the last thing that set it.

Both runtimes resolve a schema alias the same one way: strip a trailing .vN and compare the remainder against the descriptor's declared SchemaName (CultNetSchemaAliasMatching.Matches(candidate, CultDocumentDescriptor), src/GameCult.Networking/CultNetDatabase.cs:74-87; cultnet_rs::selection::schema_alias::matches ports it name-for-name and deletes the hash-stripping overload it used to carry). nameAlias is <SchemaName>.v9 and resolves through both runtimes under that one rule. hashAlias is <schemaId>.v1 and is refused as unmatched by both - it is not a wire form either runtime's production call sites ever produce or accept, and it is kept in the fixture specifically to pin that neither runtime resolves it.",
-  "//references": "R-AF, 2026-09-23: a reference's `references[].targetKey` is the only thing a stored edge actually carries on the wire - GameCult.Caching.MessagePack.CultRecordRefFormatter<T> serializes a CultRecordRef<T> as a bare key string (probed: MessagePackSerializer.Serialize on a real Design field produced the single msgpack string 'a-eq', nothing else). This fixture used to also carry a `targetSchema` per reference; it was never anything but documentation - SelectionParityVectorTests.BuildDocument and cultnet-rs's build_row both read only targetKey to construct the edge - and it is removed rather than kept as a field the wire does not have. Resolving which row an edge names is by targetKey alone, filtered to the declared role's target leaves (D9); see citer_narrow below for the shared-key shape that rule is pinned against.",

-//! `CultNetErrorMessage`/`CultNetErrorDetails` pair carrying the landed `[Key(...)]` shape, using

-//! `Convert.ToHexString(MessagePackSerializer.Serialize(message, options))`. The probe program lived
-//! at `%TEMP%\claude\probe-msgpack` (outside this repo) and was run in the `dotnet` Yggdrasil verify
-//! image via `ygg-verify.sh`; it is not part of this crate. Each case below documents the C# call
-//! that produced its bytes.
-//!
-//! This confirms the one thing that matters for byte parity here: MessagePack C#'s
-//! `[Key("name")]`-attributed map formatter always writes every declared key, in declaration order,
-//! nil for a null value - it never omits a key. `CultNetMessage::Error` is therefore encoded through
-//! the same `rmpv::Value::Map`-literal path as the crate's other raw `cultnet.schema.v0` messages
-//! (`encode_raw_cultnet_schema_message`/`parse_raw_cultnet_schema_message` in `src/contracts.rs`)
-//! rather than through the generic `serde_json::Value` round trip every other `CultNetMessage`
-//! variant uses - that path's `serde_json::Value::Object` is a `BTreeMap` (no `preserve_order`
-//! feature enabled in this crate's `serde_json` dependency), so it would emit keys sorted

-//! R-AB: `schema_discovery.rs` used to `include_str!("../../../contracts/cultnet/…")`, reaching
-//! three levels above `src/` and out of `packages/cultnet-rs` entirely. cargo-mutants builds this
-//! crate alone (there is no workspace `Cargo.toml` tying it to its siblings, so its own manifest
-//! directory is the whole tree cargo-mutants copies) - a path that escapes the package is a path
-//! that does not exist in that copy, and the unmutated baseline build failed with "No such file or
-//! directory" on every one of the 22 schemas (`rust-mut3.log`, captured on Soul's whole-cut pass).
-//!
-//! The fix vendors byte-identical copies of the 22 schemas this crate embeds under
-//! `packages/cultnet-rs/contracts/cultnet/`, git-tracked so any tool that copies just this
-//! package's directory carries them along, and repoints every `include_str!` at that vendored copy
-//! instead of the repo-root `contracts/cultnet/`. A build script staging files into `OUT_DIR` was
-//! the other option R-AB named, but it does not actually solve this: the script itself would still
-//! need to read from outside the package to find its source, and a build running inside
-//! cargo-mutants' copy would fail exactly as `include_str!` did. Vendoring - "another route that
-//! keeps every source path inside the package" - is what R-AB's ruling names as the alternative,
-//! and it is what actually keeps the crate self-contained.
-//!
-//! Vendoring is a second copy of files this repo already treats as canonical
-//! (`contracts/cultnet/*.schema.json`, the shared source multiple runtimes compile against per
-//! `docs/cultnet-selection-cut.md` section 1). A second copy can drift silently, so this test is
-//! the thing that makes that impossible without a loud, immediate failure: every vendored file is
-//! compared byte-for-byte against its repo-root original. It skips (not fails) when the canonical
-//! `contracts/` tree is not present beside the package - i.e. exactly the isolated-copy situation
-//! R-AB exists to survive - so this check does not reintroduce the same escape it is guarding
-//! against.
