Update the linked producer handoff.

Ephapax already emits access sites for its string-runtime helpers. The linked handoff still asks contributors to add the carrier in both producers and follow a shared threading plan. Update the handoff and blocker summary to distinguish the completed Ephapax work from the remaining AffineScript task.

Update the Access-site carrier handoff and blocker summary to mark Ephapax’s
string-runtime access-site emission as complete and identify AffineScript
(affinescript#462) as the remaining producer task. Remove the outdated request
for both producers to add the carrier and follow a shared threading plan.

=== [Unreleased]

==== Kernel-proofs gate on Agda 2.6.4.3, PROOF-POLICY §2.1 flags (2026-11-09)

* The `kernel-proofs` job (Contract Gate) runs in `debian:trixie-slim` with
`agda-bin=2.6.4.3-1+b2`, the prover resource-algebra, occupancy-types and
choreographic-types pin in their own CI, so this gate re-checks their
proofs on the same Agda. It ran Ubuntu 24.04's 2.6.3 before.
`tools/check-kernel-proofs.sh` refuses any Agda but 2.6.4.3.
* The gate's own Agda checks (choreographic-types' KCut slice and rejects,
the transcription table, the negative controls) run under
`--safe --without-K --cubical-compatible`, PROOF-POLICY §2.1's canonical
invocation, and with `LC_ALL=C.UTF-8`: Agda stops with exit 42 on
Unicode warnings without a UTF-8 locale.
==== Access sites carry ADR-0003 byte offsets; wire counts are bounded (2026-11-09)

* `verify_access_typing_from_module` now reads `instruction_byte_offset`
as ADR-0003 defines it: the byte offset of the access opcode within the
function body, counted from the start of the locals vector. Before, both
the verifier and `typed-wasm-codegen` used an operator index in that
slot, which contradicted the ADR and made the gate reject every Ephapax
module (Ephapax follows the ADR). `emit` now writes the byte offset of
each pinned instruction (read from `Function::byte_len` while encoding).
New `AccessTypingError` variants: `AccessSiteOffsetOutOfRange` (replaces
`AccessSiteIndexOutOfRange`) and `AccessSiteNotAnInstructionBoundary`;
`AccessSiteNotAMemoryOp` now reports `byte_offset`.
* Every `typedwasm.*` codec bounds its wire counts and length prefixes by
the bytes remaining before allocating. A count the payload cannot hold
is `CarrierError::CountExceedsPayload`, surfaced by the verifier passes
as `VerifyError::MalformedCarrier`. Before, an ownership payload with
count `0xFFFF_FFFF` requested a ~137 GB allocation and aborted the
process. `parse_ownership_section_payload` now returns a `Result`; the
versioned codecs gain `try_parse_*` variants (the `parse_*` forms keep
returning `Option`, `None` also for a malformed payload). Departure from
OCaml parity: a count larger than the payload can encode is rejected,
not zero-filled; truncation *within* an entry stays lenient.
* Docs: removed claims that a `verify_regions_from_module` pass exists,
that Ephapax compiles to WasmGC, that Ephapax emits the ownership section
on every compile, and that ephapax#251 is pending; documented that
`Layout.Types.stringLayout` models `(array i32)`, not `(array i8)`; marked
`generated/abi/` and `stdlib/` as not created; and stated that the
`VerifierSpecAgreement` / `SourceVerifierAgreement` inhabitants are true
by construction rather than a proof about the Rust verifier.
* New proposal 0007 (PROPOSED, not adopted): an `Affine` usage grade, a
`typedwasm.mode` module mode record and a separate borrow axis.

The records say nothing about what the Rust verifier does on bytes; the
only Rust link is the asserted `+MkTrustedFixture+` sites (ADR-0005).
An actual refinement statement relating the Rust verifier to the spec
is still open. This was the "`multi-week residual`" PR #74 explicitly
