A single-file store holds one record per key. push and push_all now refuse (SchemaConflictError) a write that would put another type under a key, leaving file and cache unchanged, within one batch too; the legacy envelope-array decoder refuses a duplicate key like v1. Retyping is remove-then-add.

decode_store_snapshot refuses a repeated key (Undecodable). SingleFile push and push_all
replaced by (type,key), so a write of another type to an existing key left two records
under one key, which the reader now refuses; they now replace by key alone.

load_soa installs a whole table and checks it with refuse_second_globals, but no test
reached that call (PR #15 covered put paths and pull_all). A table holding two records
of a global type is refused with CultCacheSecondGlobal and the prior view survives; a
table with one global loads and replaces the view.

#[cultcache(name)], #[cultcache(index[ = alias])] and struct-level #[cultcache(global)]
in the DatabaseEntry derive; get_by_name, get_by_index and get_global on CultCache; a
second record of a global type under another key is a typed CultCacheSecondGlobal refusal
on every write path and on load.

Each test file carries the snippet between markers; the docs show it verbatim and a second test in the file fails if the README block drifts. Matrix cells for Rust and Python CultCache now link them.

The Unity list no longer calls MarkFlushSucceeded removed and places HeaderFor and the CacheBackingStore members where apicompat finds them. cultnet-rs gains a CHANGELOG. The store-composition contract moves DecodeDocument to the codec and states that a call's registry serves that call only. Docs only.

The stamp functions (Rust refuse_unread_format, TS refuseUnreadFormat) are the single owner of the stamp rule, accept v1 and v3, and are called only from the one reader every whole-store write runs under the lock. The fix's header peek (TS refuseUnreadStoreBytes, peekHeader) is deleted. Its tests that v3 is refused and that a stampless file is healed are dropped; the reversal is a Breaking line in the Rust and TS CHANGELOGs. The 0xff-after-stamp test now runs over v1 and v3.

Stamp rule runs on slot 0 before the body is scanned (JudgeStamp). DescribeHeader names a v<N> header that carries a suffix. Rust store_header walks on the grown stack. Drift tests declare Wide's id compatible (ownership by declaration). Mesh write-guard tests expect the typed refusals.

Identity: C2a's StoredSchemaId/StoredVersion owns; main's PersistedSchemaId, PersistedIdentity and both MarkWritten are deleted. Stamp rule: ReadStore judges the stamp before the body. Flush over damage refuses (merge-r1-precedence). Mesh single-file writes route through SingleFileMessagePackBackingStore. TS: store-file.ts commits, C2a's header handling kept. Rust: C2a's readable_store_format in front of the grown decoder. Build not yet verified at this commit.

describe_decode_error keeps serde's own value-free texts for missing and

Legacy and v1 reads on 64 KiB, redb pull_all and compare-and-swap on 104 KiB,
and one Largest level on 88 KiB, the sizes where a plain from_slice or a missing
outer maybe_grow dies in release as well as debug.

The README and decode_payload claimed the calling thread needs only its own
frames. Measured, the door has a payload-independent floor (release 56 KiB vs
16 for a same-signature non-decoding function; debug 104 vs 88). Say so, and
replace "Windows not yet verified" with the one by-hand Starfire run of
decode_stack on x86_64-pc-windows-msvc.
Co-Authored-By: Claude Sonnet 5.5 <noreply@anthropic.com>
Measured on Yggdrasil: the decode needs 56 KiB (Wide32) and 80 KiB (Largest) in
debug on a thread that returns a bool; returning the record through
std::thread's own frames adds several copies of it, so the tests box it and
size threads at 96 KiB and from 160 KiB.

decode_grown checks the stack before any frame that holds T, then serde_stacker
at every container; decode_payload walks the nesting bound and calls it; the
legacy envelope array, redb reads and v1 snapshots decode through it too.
Red zone 512 KiB against MAX_RECORD_INLINE_BYTES = 16 KiB, which the
DatabaseEntry, CultSlots and CultUnion derives assert at compile time.
cultcache-rs-derive 0.2.0.

Sixteen conflicted files resolved by the spec's rule: main owns payload
ownership, bounds and the Clock seam; C2a owns persistence semantics and exact
binding. MintStoredAt is internal static (previous, now); the cache and the
store pass their cache's Clock. Package versions are main's. The cultmesh-ts
payload-parse acceptance and its test are deleted under retire-schema-alias;
peer snapshot reads take the schema's own id, else an id the definition lists
as compatible. The held firstRecordAtKey fallback is removed: main's handles
take definitions only, so nothing could reach it.

A payload inside the 256 nesting bound no longer depends on the caller's
thread stack: the rmp-serde deserializer runs under serde_stacker with a
256 KiB red zone and 2 MiB segments. Adds tests/decode_stack.rs (child
process per test, sized decode thread) and renames the 2 MiB union_parity
stack test to a 1 MiB pin.

Both raw write doors run the one check_payload_depth that decode_payload runs first, before any
store is touched; decode_payload is public so envelope readers elsewhere decode through the same
helper. Tests: union arms, maps and arrays at 256 and 257 through both doors, a batch that stages a
valid entry beside a deep one persists neither, the read vectors enter by a store file written
behind the cache.

Pins ext-key-class-arity (fixext 1, timestamp, ext 8) and the nil-slot refusal at the

Mutation survivors of the first run: the unwrap_or(usize::MAX - k) fallbacks were equivalent
mutants, so a truncated header now returns None through the one helper. Child counts and long
lengths (map16/32, array16/32, str/bin/ext 16 and 32 bit) are tested with skipped bytes that
read as containers when a skip stops short. Builds.

Wrap, Floor and Ceiling fixture arms; bounds-outcomes.msgpack looped through the raw decoder

check_payload_depth walks MessagePack headers iteratively and refuses the first container past
MAX_PAYLOAD_DEPTH (256); decode_payload is the only payload decode (get, get_all,
get_all_with_keys, finish_prepared_entry, envelope validation), so write is refused through
finish_prepared_entry. Derive: nil arm slots refused naming union and key, ext arm keys classed
non-integer, generated generics and local items prefixed (types named D, S, A, E, ArmKey now
derive), slot keys capped at 65535 at definition, SlotRecord requires a hidden method only the
derives emit, DatabaseEntry/CultSlots expansions are functions the type/schema/generics refusals
are unit-tested through. Tests follow in the next commit; this commit builds.

Key attributes (variant, field, entry type/schema) are refused when repeated. A CultUnion key
parses as the reference's Int32, negatives included; a key outside it is a compile error. Decode
classifies the key as the reference does: non-integer, outside Int32, undeclared (named), and a
pair of the wrong length is refused before its key is read; no value is echoed beyond the
undeclared key the reference names. The SlotRecord trait, implemented by the shared slot
generator, bounds an arm payload, so a String or Option arm is a compile error. compile_fail
fixtures use keys other than 0; the derive crate's unit tests assert each refusal's message.
Unverified: committed before the first build; the verification job runs next.
