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.

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.

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.

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.

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.

One slot generator now serves DatabaseEntry and CultSlots. CultUnion writes

Absent writes, a store it reads is left byte for byte, and anything the reader refuses (an unreadable file, a dangling link) is refused. The readability manifest walk now runs a soft flush over every vector, so TypeScript and Rust are pinned by the same files.

The seam sat before the call, so a mutant that swallowed the real rename's result was invisible to it. It now makes the rename itself fail, on both platforms.
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
store_header is the only reader of a store file's leading bytes. It returns the header slot (a MessagePack str only, never bin, as in C#, TS and Python) and separately the proof that the bytes are one whole array, so a newer store cut short after its header is still named unsupported. leading_header, read_array_header and read_string are deleted. decode_store_file takes the header the reader already found.
Vectors bin-header-v1/v3/v9 join the readability manifest as refuses x4. Tests: a rename fault step (WriteStep::Rename) shows a failed rename is NotReplaced, the store intact and no staging file left; every merging writer refuses through a dangling link; the unsupported-format refusal names v1 and v3 and echoes only ASCII-digit headers.

R1's rule that the header alone decides an unreadable-format store (a newer store
cut short is not damaged) is kept as leading_header, asked before the whole-file
proof. A directory at the store path now stops a write at the read as an I/O
error, so the two tests that used it to reach a failed rename assert that instead,
and the two c2a header tests assert R1's UnsupportedFormat kind, not c2a's old text.

The merge left store_header's visitor unclosed (does not build). R3's pin that a
whole-store flush replaces a dangling link survives the single reader: the reader
still refuses the link as an I/O error, and the flush, which has no content to
carry from a link that holds none, writes v1 over it (Rust write_all_unlocked, TS
pushAll).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
R1's rules win where both sides decided the same question: a zero-byte file is
not a store (refused as unreadable in every runtime), only nothing at the path is
empty, a dangling link is an I/O error, refusals never echo stored values and echo
a header only as cultcache.store.v<digits>, writes report Rejected, NotReplaced
and ReplacedNotDurable. C2a's rules win on what it added: the v3 element-id
header, variants, whole-file proof, typed unreadable errors in C#, TypeScript and
Python. Rust keeps R1's CultCacheStoreUnreadable{path, kind}; C2a's
StoreUnreadableError is deleted. The readability manifest's zero-byte row is
refuses x4.

- The fixture gains an older entry listing the id ahead of the one that
owns it, and the whole-store write carries the record under the
registered type a Rust cache's pull gives it, not the entry's name.
Kills the own-id lookup flip and the ||-to-&& flip in the entry filter.
- A store path that cannot be read (a directory) is an error, not an empty
store (the NotFound guard had no test).
