docs: step-3 rewrites — OQ-39/40 resolved, C-08 closed, channel-operations.md put/control/resources contracts, review 010/011 closed with the S-01 sketch corrected

- open-questions.md: OQ-39 → ADR-052, OQ-40 → ADR-053 (resolutions replace
  the deferred-until-needed posture)
- channel-operations.md: the put contract (initiator allocates + streams,
  reserved input key, one response, acks-in-result sentence), the control
  routing (ADR-052), the enumerator aggregation (ADR-053), the
  connection-owner paragraph's pub-era correction, the ADR table rows
- ADR-051 §6: PubTypedOpen → the put translation; ADR-047's 2026-09-06
  amendment records its era honestly (the dynamic half is now ADR-053)
- review 010: all four findings resolved (with the S-01 sketch correction
  so the published record stops carrying the wrong-graph reading)
- review 011: closed (all seven pins implemented + gates landed)
- review 001 C-08: resolved note (odd/even + adopt, implemented)
- AGENTS.md: the 'Stub Guard' section — the not_implemented grep is part
  of cargo test; the registration invariants and the implement-or-stop
  ruling are release-blocking

+## Stub Guard (release-blocking)
+
+Four registered-but-always-failing stubs shipped across nine published
+versions (reviews 010/011). This class is now release-blocking in both
+directions:
+
+1. **Test guard**: `cargo test --test stub_guard` (part of `cargo
+   test`) fails if the string `not_implemented` appears anywhere in
+   `src/`. A "loud failure" stub is still a stub.
+2. **Registration-time invariants** (ADR-047 amendment 4 §4.8): a
+   marked (`channel_open`) spec refuses the generic registration path
+   (`OperationRegistry::register`, `CallConnection::register_imported`,
+   `op/register`) and refuses `publish_schema`; the sanctioned
+   registrations are the channel wrapper family
+   (`register_openable*`, `register_pub_openable`,
+   `register_relay_openable`).
+3. **The ruling**: implement-or-stop-advertising before any publish.
+   The only permitted deferral statement is "not this session" — never
+   "next version", "not v1", or any bucket that parks a decision on an
+   unknown future release. Every handler that registers on a
+   discoverable surface must be capable of succeeding.

+A marked `Pub`-typed open op is the **put** shape: the data plane is

+the authoritative shape — a serving-loop `PublishStream` sketch was
+considered and rejected, it is ADR-046's *unmarked* pub semantics):
+
+1. **The initiator allocates and writes immediately.** The putter
+   allocates the channel id on its own side (connect side → odd, per
+   the ADR-047 §5 odd/even split), inserts the **reserved input key
+   `"channel_id"`** into the open op's input, and streams bytes on the
+   channel before the open resolves — the early-arrival parking
+   (ADR-051's tested pre-adopt buffer) covers the responder-adopts
+   race. Zero `call.published` on marked ops: chunks on the call plane
+   are rejected loudly with `channel:publish_chunks_rejected` (the
+   first chunk writes the rejection in the initiator's direction; the
+   handler is never fed). An unmarked `Pub` op is an ordinary ADR-046
+   sink (JSON chunks, `publish_schema`); it does not ride the channel
+   machinery.
+2. **The responder adopts.** `ChannelCore::register_pub_openable` is
+   the only registration seam: the wrapper strips the reserved key
+   pre-validation (dispatch layer, before `input_schema`) and adopts
+   the given id (`adopt_channel` — the remote parity range enforced;
+   failure replies `channel:open_failed` with reason `adopt_failed`).
+3. **The wrapper is the responder of record:** `check_open` → adopt →
+   bounded establisher (offer validation + ack fields +
+   `Establishment::with_control`, ADR-049 amendment 3's mechanism) →
+   the `PubOpenHandler` runs on the adopted channel's `Connection`,
+   **awaited inline** → the standard completion teardown → **one
+   response**, merge order pinned:
+
+   ```
+   { "channel_id": <adopted> } → ack fields → handler result
+   ```
+
+   (the handler result wins on key collision — its computed result
+   postdates the ack; a handler `Err` IS the response, and the channel
+   tears down).
+4. **The ack-timing sentence (protocol semantics):** a sink op gets
+   exactly one `call.responded`, produced after the handler completes
+   — a putter stream-waits nothing; the establishment ack is
+   informative-in-result, never a gating ack. The fetch/put asymmetry
+   is direction-inherent: fetch (`Sub`) acks at establishment (the
+   `{channel_id}` response precedes any byte); put (`Pub`) acks in the
+   result. A putter that waits for the ack deadlocks — this sentence
+   is the contract, not per-consumer folklore.
+5. **The putter-facing client shape:**
+   `ChannelClient::open_pub_channel(operation_id, input, alpn)`
+   allocates the odd id, sends the open op in the background, and
+   returns `(id, send, recv, reply)` immediately; `reply.resolve()`
+   is the awaited merged response.
+
+**Error codes** (the pub path):
+
+| code | meaning | retryable |
+|------|---------|-----------|
+| `channel:open_failed` | establishment failure (ADR-049 §3 vocabulary) or adoption failure — new reason `adopt_failed` (collisions, cap, out-of-range reserved ids; ADR-047 amendment 4 §4.4) | false |

+| `INVALID_INPUT` | absent/non-u32 reserved `channel_id` key on a marked pub op (ADR-047 amendment 4 §4.3) | false |
 
 The hub-as-proxy pattern (ADR-042, ADR-047 §1) composes on top: a
-worker publishes to the hub, the hub owns the resource, and consumers
-subscribe from the hub. The broker (topic registry, `Pub`↔`Sub`
-matching) is a hub concern, not an alkcall concern (ADR-047 §1, Gap B).
+worker publishes to the hub, the hub owns the resource, consumers

+acks-in-result — an establisher awaiting the spoke's response would
+deadlock the leg), pumps consumer bytes → spoke leg, and mirrors the
+spoke's single response with its reserved key stripped.

+Closed — filed 2026-10-13. From alkblobs (the downstream crate paused on
 review 010 S-01; its ops-put task gates on this surface). Purpose:
 correct review 010's S-01 remediation sketch before the amendment is
 drafted, enumerate what the amendment must pin so one publish
 (0.9.0) fixes all four stubs right, and record the downstream
 requirements and non-requirements from the consumer seat.
 
+**Closed 2026-10-13:** all seven §2 pins are implemented and pinned in
+ADR-047 amendment 4 / ADR-052 / ADR-053 / ADR-022's 2026-10-13
+amendment, with the §3 verification gates landed as tests
+(`channels::operations::pub_open_tests`,
+`channels::hub_leg::gate2_tests::gate_pub_relay_put_end_to_end`, the
+registration-invariant tests in `registry::registration` and
+`registry::op_register`), the guard is `tests/stub_guard.rs`, and the
+docs rewrites below are done. The §6 sequencing concluded.
