Subject: [PATCH 1/7] feat(tb): Harbor host completion-gate bind + tip L6
 digests.

Native TB runner binds Passed host verification reports to mutation digests
so tip Core can finish Harbor tasks without a gate waiver. Harden the bash
cancel hermetic under parallel load, and record tip L6/Flash RC evidence on
b91462d3 for the Enterprise GA board.

Subject: [PATCH 3/7] feat(dm): DM-PROD1 host harness with Redis CAS, leases,
 and Boyue embeddings.

Adds the dm-prod1-host example (Redis IndexRevisionCas VectorIndex, SET NX EX
fenced lease, failover, restart, drift) and records the passing host pack
/tmp/dm-prod1-host-b7b239a8 in ROADMAP and HARNESS_CONVERGENCE.

+## Host harness
+
+`core/examples/durable_memory_prod1_host` produces a report pack covering every
+row above against real backends. It is gated behind the `dm-prod1-host` Cargo
+feature, which is the only thing that pulls in the `redis` client; no library
+module depends on Redis.
+
+```bash
+./scripts/harbor/run_dm_prod1_host.sh
+```
+
+The script sources credentials from `scripts/harbor/.env` (materializing it from
+`.a3s/config.acl` when absent), preflights Redis, builds `--release`, runs the
+harness, and prints the pack path.
+
+| Input | Default | Notes |
+| --- | --- | --- |
+| `BOYUE_API_KEY`, `BOYUE_BASE_URL` | required | Read from the environment; never written to the pack |
+| `A3S_DM_PROD1_EMBED_MODEL` | `text-embedding-3-small` | Served dimension is probed, not assumed |
+| `A3S_DM_PROD1_REDIS_URL` | `redis://127.0.0.1:6379/15` | Database 0 is refused unless `A3S_DM_PROD1_ALLOW_DEFAULT_DB=1` |
+| `A3S_DM_PROD1_WRITERS` | `8` | Independent sockets racing one shared index prefix |
+| `A3S_DM_PROD1_LEASE_TTL_SECONDS` | `600` | Not renewed, so it must outlive the run |
+| `A3S_DM_PROD1_PACK_DIR` | `/tmp/dm-prod1-host-<code sha>` | Contains `report.json`, `MANIFEST.json`, `HYGIENE_OK` |
+
+Every Redis key the harness creates lives under a per-run prefix
+(`a3s:dm-prod1:<random>`) and is removed by scoped `DEL` on exit. The harness
+never issues `FLUSHDB`.
+
+What the harness injects, rather than what ships in `a3s-memory`:
+
+- `RedisVectorIndex`: a `VectorIndex` whose `mutation_consistency` is
+  `IndexRevisionCas`, implemented with `WATCH` / `MULTI` / `EXEC` on a revision
+  hash and a `sha256` history digest chained over published revisions.
+- `RedisLeasePolicy`: `SET key value NX EX` with `INCR` fence tokens and an
+  owner-compare Lua release.
+- `BoyueEmbeddingProvider`: OpenAI-compatible `POST /embeddings` with recorded
+  per-request latency, token usage, and returned-vector L2 norms.
+
+### Caveats retained in the pack
+
+Each satisfied row carries its own `caveat` in `report.json`. These narrow the
+row without weakening it, and they are the honest residue of a single-host run:
+
+- Horizons are single-process and minutes-scale. Multi-day wall-clock decay and
+  cross-deployment session horizons are not covered.
+- Concurrent-writer load is one process over one Redis database. Multi-host
+  writer fleets are not covered.
+- Failover is a client-side connection drop (`CLIENT KILL`) plus an
+  independently recreated keyspace. Redis Sentinel or Cluster primary promotion
+  is not exercised.
+- The epoch lease is not renewed; its TTL simply outlives the run. There is no
+  lease-renewal loop to qualify.
+- Semantic recall places the paraphrased target query inside the bounded
+  candidate set but not always at rank 0. The observed rank is recorded as
+  evidence rather than gated on, so the row grades the durable-memory machinery
+  instead of the embedding model.
+
 ## Active-only binding
 
 Production hosts must use `DurableMemorySession::active_recall` only.

 | `DM-RECOVER1` | Delivered | A host-persisted semantic-refresh checkpoint can recover an unchanged schedule without re-embedding or republishing | Recovery omits the repository-history token and always verifies one complete Active snapshot; a skip additionally requires the exact vector-index history token, revision, and full status, while unrelated repository histories, colliding index status, a missing vector token, or any drift conservatively rebuilds; the next stable tick returns to the zero-snapshot path |

Subject: [PATCH 5/7] release: prepare a3s-code 9.0.0 channel cut.

Fold Meta Harness, CompletionAttestor, fixes, and the DM-PROD1 harness into
[9.0.0]; keep Apofasi under [Unreleased]. Record TB-QUAL1 as waived by product
decision, so Enterprise GA is not claimed. Complete the version bump (Python
bootstrap, Node examples lock, Go module path sdk/go/v9) and move the docs
current line to v9.0.0. Correct the 8.7.0 notes: that tag's release failed CI
and never published.

-  npm `@a3s-lab/code`, Python bootstrap / wheels, and Go module tag
-  `sdk/go/v8.7.0`.

 ## What's new in 8.7
 
+8.7.0 was tagged but never published; its changes first ship in 9.0.0.
+
 - **a3s-vec lexical FTS (8.7.0).** Workspace FTS uses pure-Rust `a3s-vec`
   (`a3s_vec_fts_v1`). On-disk `zvec_rust_fts_v1` generations are incompatible
   and rebuilt.
 - **`web_search` usable rows succeed (8.7.0).** Default cascade is API, then
   HTTP/RSS, then headless. Non-empty usable rows are `complete` or `partial`
-  success (#161). Prefer **8.7.0** on npm/crates.io/PyPI.

 | `CAR-02` | Delivered | Tool-request/result evidence, per-call input/usage diagnostics, and the Rust-host immutable-content adapter retain every raw Tool result plus compacted change sides behind exact content-addressed references (the digest must be a complete URI path segment; the local fallback exposes create-only replay with conflict fencing) | Cloud owns adapter authorization, provider selection, projections, and object lifecycle; Gateway usage remains the billed request ledger |
