A cacheless write that re-enters its own store's hold now consults Cache first, so a journal's WriteDocument or WriteRecord gets the same refusal during an attach as after it (the attached text); the re-entry text no longer names an attach's pull. InStoreHold takes the store instead of its gate.
CacheBackingStore.GateTakes (internal, thread-static) counts the gates Gate takes; OneStoreCallTakesAtMostThreeGatesUnderFailingAttachChurn asserts at most three per call under failing-attach churn, which pins the stale-guess loop (M4b).
The contract and AddBackingStore say what holds: other threads may guess the tentative cache, but none runs a body against it.

The folded-in writedoc case used to assert the refusal left the attach's registry in place and a later PullAll succeeded; the per-entry-point test now asserts that for every entry point.

The previous code commit's AJournalOnTheAttachingThreadCannotReachItsStore failed all 21 cases:
AddAsync mints its own key, so "later" never appeared. That commit builds; its new test is red.

Cache is the one attachment fact. AddBackingStore, the only writer, publishes it right after the
registry loan and sets it back to null in the catch, all inside its hold of both gates, so a
journal's store call during the attach is refused as it is after it (it used to stage or write
records the cache never admitted). Gate loses MaxPasses and its loop: the guessed cache's gate,
the store's gate (where Cache cannot change), then the settled cache's gate. Tests: one per store
entry point through a real attach (single-file and directory), each asserting the attaching cache
and a fresh cache agree after a flush; the second-store refusal pinned before the same-store one;
the three attach tests renamed to the published-cache shape. The old
AJournalOnTheAttachingThreadCannotWriteItsStoreCacheless is the writedoc case of the new test.
This commit builds; docs follow in the next commit.

Fixes two tests of the previous commit that failed on their own fixtures (the inner call's
exception was swallowed in the hook; a variant that shares its base's name is refused). Builds.

InStoreHold gains a cacheless flag: on re-entry of the same gate a cacheless call throws
instead of running, so the attach's hold (until it publishes Cache) and an enclosing store
call's user code cannot write the store behind the cache. Gate passes the flag; no field
mirrors Cache. Tests through a real attach and a nested cacheless write, a header pin for
attached variant stores, contract and CHANGELOG.
Builds on the previous commit; neither is built or run until the verify job.

Deletes CacheBackingStore._codec and UseRegistry's codec parameter, the reflection LentCodec
test helper and the bare-store codec test. The cache re-resolves every pulled variant with its
own codec when it admits the load.
Not yet built or tested; the verify job at the head covers every commit.

UseRegistry(registry, codec) is the single writer of both loans; the pull builds
variants with the store's own codec, a failed attach takes both back through the
same call, and AddBackingStore sets store.Cache last. Cache now goes from null to
a cache at most once, so Gate's retry makes at most two passes: the 1,000 stale
cap becomes MaxPasses = 2 and its comments say why.

Kills the survivors of the first mutation table (no recheck in the store branch, a Gate() that refuses the held cache, a stale
retry result, a same-store reentry refusal).

CultCache owns the per-thread gate facts: _storeHeld joins _held. InStoreHold marks the store gate; Gate() is where every
cache gate entry (holds and reads) refuses while that mark is set and the gate is not already the thread's. A getter run by a cacheless
call or an attach that reaches a cache or a second store throws instead of deadlocking against an attach.

Re-entrant getter during a cacheless write (read and write), a getter against the attaching cache, an attach pull that enters
a second store, and readers queued on a failed attach (snapshot, PullAll). Every thread join is bounded.

CacheBackingStore.Gate<T>(body, cacheless) reads Cache as a guess, takes that gate, checks the guess under it
and retries when stale. A cacheless call's refusal is the store-gate branch's validation outcome, in the same hold
as its body. WhileDetached becomes UnderStoreGate over CultCache.InStoreHold; AddBackingStore tests Cache, not Loaded.

old-reader-refusal.sh gains gate <runtime> and per-runtime old revisions (b8fc5eb0 = cultlib-unity-v2.0.1,
02cf04b5 = cultcache-rs-v0.3.1, 45c2f400 = cultlib-unity-v1.0.60). C2aGateWriter writes the live v3 and v5 stores.
OldReaderGateProbe replaces OldReaderV3Probe. The vectors themselves follow.

The call no longer picks its gate from a read of Cache (Held), so a call queued on a cache's gate during an attach that then fails
cannot run beside a second cache's attach. Lock order: cache's gate then the store's, in the attach only.

Hand mutant T4 (lead >= 0x90) survived; the empty-array case now carries a newer stamp after it.

Mutation of the restore line and of the header's Holds(runtime type) survived the previous tests (Stryker/hand mutants C1, C7). Not yet built.
