 ## Unreleased
 
-- MemHub multi-user hardening (follow-up to #250):
-  - Read responses name the user they were read for: `user_id` (the one
-    asked for, `local` by default) is now on `GET /api/v2/memory-library`,
-    `/memory-library/layers`, `/user-profile`, `/home-summary`,
-    `/memories/graph`, `/raw`, and `POST /api/v2/context/search`,
-    `/api/v1/recall`, `/api/v2/memories/ask`. `ask/stream` carries it on its
-    first (`recall`) event. The Host Bridge context validator accepts the new
-    field and still accepts a Core without it.
-  - `DELETE /api/v2/memories/{id}` answers 404 `memory_not_found` for another
-    user's memory and for an id that does not exist (the same response, so
-    existence is still not revealed), and also when the SDK finds nothing to
-    delete; 204 only when the caller's own memory was deleted. The App treats
-    that 404 as already gone (a double-click delete no longer shows an
-    error); `memhub memories delete` prints "未找到记忆 <id>（可能已删除）",
-    exits 0, and its JSON is `state: "committed"` with `already_gone: true`.
-  - Hermes never reads a `profiles/` directory at any depth (scan, detect and
-    live sync), so a root granted above `~/.hermes` cannot pick up another
-    user's profile. Connecting refuses a root that is the `profiles`
-    container itself (422 `hermes_root_is_profiles_container`) and a root
-    equal to, containing or inside another user's active Hermes grant (409
-    `hermes_root_overlaps_other_user`, symlinks resolved); `local` on
-    `~/.hermes` with another user on `~/.hermes/profiles/<name>` stays
-    allowed. The CLI explains both codes.
-  - `memhub sources connect --user-id` with an invalid id now says the user
-    id need not equal the Hermes profile name (e.g. `--user-id wife-work
-    --root ~/.hermes/profiles/wife:work`).
+- MemHub App now exposes the complete memory-mode lifecycle. New installs
+  explicitly choose lite or pro during onboarding; pro completes only after a
+  generation model is active, while ultra remains an advanced Settings choice.
+  Settings shows mode effects, graph backfill, the default 03:00 evolve
+  schedule and manual evolve. The memory page shows original conversations in
+  lite and advanced memories in pro/ultra. Existing installs remain pro unless
+  the user changes them, and embedding maintenance blocks mode/evolve changes.
 
-- MemHub's DeepSeek Harness app page can grant recall again (#230). The
-  "一键插入应用" switch used to be greyed out with `unsupported_host`, and a
-  profile installed from the CLI stayed `install-only` with no way to approve
-  it. The one switch now covers every detected profile
-  (`deepseek-harness:<profile>`): on installs each profile's MCP patch and
-  grants recall, off removes the patch and revokes the grant. The page lists
-  each profile with its state, and names any profile that failed while
-  keeping the others. While the switch is on, a profile created later is
-  installed and granted automatically, without restarting MemHub; the Runtime
-  also no longer fails every host read when it meets a profile created after
-  it started. The harness docs no longer describe an unmounted sources page.
+## Hy Memory 2.0.14 — 2026-11-04
 
-- MemHub's `deepseek-harness` source imports session files whose names carry the
-  format generation: `session.v3.jsonl.zstd` and `session.v4.jsonl.zstd` are now
-  discovered alongside the original `session.jsonl[.zstd]`. Discovery accepts
-  any `session[.vN].jsonl[.zstd]` name and the header's `version` decides
-  whether the session is parsed (v0/v3/v4) or refused as `unsupported_schema`.
-  A refused file is reported and keeps no cursor, so the release that learns
-  its format reads it from the top.
-  v4 tool results, which are written as plain `text` blocks rather than
-  `tool-result` blocks, are read through the same clipping and credential
-  scrubbing path. Previously every versioned session was invisible: the import
-  job completed with `discovered 0` while the files sat on disk.
+- `search()` / `async_search()` take an optional `statuses` for explicit
+  L1_RAW search (`layers=["l1_raw"]`, or any search in lite mode), e.g.
+  `statuses=["active", "shadow"]`, so raw turns a pro extraction already
+  shadowed can still be searched. Default stays active-only. Raw hits now
+  report their real `status`. Passing `statuses` to a non-raw search or to
+  `scene="all"` raises `ValueError` instead of being ignored.
+
+## Hy Memory 2.0.13 — 2026-11-02
+
+- A model failure during a write now reports failure and stores
+  nothing. **Behaviour change for direct SDK users:** writes that used to
+  return `success: true` in a degraded state now return `success: false`;
+  retry them with a new `request_id` once the model is back.
+  - Reconcile (pro / ultra `add` and `add_extracted`): when the reconcile model
+    call fails, returns HTTP 200 with empty content, or returns a reply that
+    cannot be parsed, or reconcile raises before anything is stored, the write
+    used to fall back to adding every extracted memory as-is (no dedup or
+    evolution) and report success. That fallback is removed, with its
+    `degraded` / `degraded_reason` result fields. The write now returns
+    `success: false`, `error_code: 502`,
+    `agent_error_code: "RECONCILE_FAILED"`, and the cause in the new
+    `reconcile_error_code` (`LLM_UNAVAILABLE`, `EMPTY_RESPONSE`,
+    `JSON_PARSE_FAILED`, `RECONCILE_EXCEPTION`). None of the new memories are
+    stored, the episode counter does not advance, and `add` rolls back its
+    raw turn the same way as an extraction failure
+    (`l1_rollback.retry_safe: true`). An empty 200 reply was previously
+    counted as "no changes" and reported success with 0 memories; only a
+    literal `[]` reply still means that. `RECONCILE_ENABLED=false` is a
+    configuration choice and still writes directly.
+  - Working / coding path: an extraction model failure used to return
+    success with 0 operations. It now returns `success: false` with
+    `agent_error_code` `LLM_ERROR`, `EMPTY_RESPONSE` or `JSON_PARSE_FAILED`.
+    A model that answers with nothing worth remembering is still a success.
+    An embedding failure used to store the experience or fact without a
+    vector, where search never finds it, and report success; it now returns
+    `EMBEDDING_FAILED` and the node is not stored. A fact embedding is checked
+    before any older fact is superseded. A failed write no longer appends its
+    turns to the recent trace and records no `chain_rounds`.
+    With `MEMORY_CODING_VERBATIM_FALLBACK_ENABLED` turned on, extraction
+    failures keep the verbatim fallback.
+  - Working / coding reconcile: when the experience reconcile or the fact
+    reconcile model call fails, returns empty content, or returns a reply that
+    is not a JSON object with an `ops` list, the write returns
+    `success: false`, `agent_error_code: "RECONCILE_FAILED"` and the cause in
+    `reconcile_error_code` (`LLM_UNAVAILABLE`, `EMPTY_RESPONSE`,
+    `JSON_PARSE_FAILED`), the same as chat. Before, experience reconcile fell
+    back to adding every draft, and fact reconcile inserted the new fact
+    without superseding older ones. Both model decisions now run before
+    anything is stored, so a failure in either leaves no experience or fact
+    from the write and supersedes no older fact. An experience reply of
+    `{"ops": []}` is a valid "no changes" decision: the write succeeds and no
+    experience is stored. A non-empty `ops` list with no recognizable op is a
+    parse failure. A fact reply of `{"ops": []}` inserts the new fact without
+    superseding anything. Fact reconcile still makes no model call when there
+    are no candidates.

+- Memory writes retry themselves (#278), each time under a new SDK request
+  id after checking whether the previous one landed; interrupted writes
+  re-run automatically. A model provider failure (401/403, 404, 408, 429,
+  5xx, timeout, unreachable) keeps the job pending in place without spending
+  a retry, and a per-profile circuit breaker paces the queue (5 s doubling to
+  180 s, one probe job at a time). Any other failure is retried after 30, 60
+  and 120 s, then `failed`. With `hy-memory==2.0.13` a model failure is no
+  longer a silent success, and a failed job's `error_code` names the SDK's
+  cause (`hy_sdk_reconcile_empty_response`, `hy_sdk_llm_error`, ...) rather
+  than `hy_sdk_write_failed`. **User-visible:** the manual 重新整理 button,
+  the "整理结果不确定" display and
+  `POST /api/v1/memory-processing/retry-unknown` are gone; a banner
+  ("模型配置有问题……记忆暂停处理，已有 N 条在排队") with a button to the model
+  settings shows while a model problem pauses processing, and clears on
+  recovery.
+- Queue, WAL and recall (#278): the WAL stays bounded (64 MiB journal limit,
+  idle `TRUNCATE` checkpoints); a disabled or revoked source's jobs are
+  `suspended` and resume when it is turned back on; SDK writes and recall
+  reads use separate thread pools, and recall has a total budget (504
+  `recall_timeout`, `broker_timeout` in clients) instead of starving behind
+  stuck writes.
+- One Runtime per data dir (#273). App quit asks the service manager at quit
+  time: an enabled background service is never stopped, a disabled one has
+  every Runtime of the data dir stopped (only after an authenticated identity
+  check), and an unknown state stops nothing. At start the App adopts a
+  Runtime of the same build, replaces an older one, and silently adopts a
+  newer one. The tray quit label follows the current state.
+- DeepSeek Harness: the app page's one switch installs and grants recall for
+  every detected profile, and keeps new profiles granted without a restart
+  (#230); versioned session files (`session.v3.jsonl.zstd`,
+  `session.v4.jsonl.zstd`) are imported, and v4 tool output goes through the
+  same clipping and scrubbing (#175).
+- The packaged Runtime accepts only a full 40-character commit, lowercased; a
+  malformed `ONE_MEMORY_COMMIT` fails the build (#235, #236).
 - Search and recall pass through the SDK's search parameters with server-side
   score floors; the memory library filters by layer; `/api/v2/raw` returns
   data again; v2 source and import routes; profile version history.
