+
+# Clean Main Worktree Workflow
+
+For every task that may edit code:
+
+1. Before editing, run `git fetch origin main`; if it fails, stop rather than use a stale ref.
+2. Never develop in a dirty, detached, or stale primary workspace.
+3. Record `BASE_SHA=$(git rev-parse origin/main)`, then create the task branch and isolated worktree from that exact SHA.
+4. Verify the worktree is clean and its initial `HEAD` equals `BASE_SHA`.
+5. Keep one task per branch/worktree and include only files required by that task.
+6. Never delete, prune, force-remove, or reuse another task's worktree to resolve a path, branch, or registration collision.
+
+Before pushing or opening/updating a PR:
+
+1. Apply intended formatting/fixes, then commit only the current task.
+2. Fetch `origin/main` again; if it fails, stop.
+3. If main advanced, integrate it before delivery. Rebase is allowed only for an unpublished branch used by this task alone; never rewrite shared history without approval. Otherwise merge main or ask.
+4. Re-review files changed by both sides; a conflict-free integration is not proof of semantic compatibility.
+5. Run only checks that are necessary and proportionate to the changed files and risk. Prefer focused tests. Do not run repository-wide tests, type checks, or builds by default.
+6. Do not let optional, slow, or stalled local checks block opening or updating a PR. Stop them when appropriate, report exactly what ran, passed, failed, or was not run, and rely on required CI before merge.
+7. If any check changes files, inspect and commit them, then repeat the relevant checks.
+8. Require a clean worktree after checks so the tested tree equals the pushed `HEAD`.
+
+Before merge:
+
+1. Fetch `origin/main` again; if it fails, stop.
+2. Record the fetched base SHA and PR head SHA. Required CI must validate the merge result produced from those exact revisions.
+3. Confirm the PR targets `main`, contains only intended files, and has no failing or pending required CI.
+4. If either SHA changes, repeat overlap review and validation before merge.
+
+Never discard or clean an existing dirty workspace without explicit user approval.

 ## Unreleased
 
+- MemHub host capture hooks no longer write the database. `one-memory
+  capture <host>` used to open the main SQLite file from its own short-lived
+  process on every hook, re-create the retired `evidence` / FTS tables on an
+  SDK-authority home and write the write queue outside Core's single writer,
+  contending for the file lock with Core and with other hosts' hooks. It now
+  reads only the runtime receipt and token and posts the hook's JSON to the
+  running Core (`POST /api/v1/live-capture/{source}`, 1.5 s budget). Core
+  applies the same gates (grant, sync switch, rejection counting, automated
+  sessions, the Cursor/Claude Code rule; the migration fence stays on the hook
+  side) and stages the turn in-process through the live file-sync path. When
+  Core is not running the turn is dropped silently; nothing falls back to a
+  local write.
+- MemHub no longer sends one turn to the SDK twice when a host's hook and live
+  file sync both see it. The two lanes gave the same message different
+  identities (the hook carries no workspace and often no message id) and
+  separate assembly rows, so both were written as raws. Hook input for a
+  source that live sync reads from its own files (every hooked host except
+  Qwen Work, while live sync is on) is now left to the file path; only a
+  source without file polling is staged from its hook. Tables an older hook
+  re-created on an SDK home are dropped by the existing startup cleanup.
+
+## Hy Memory 2.0.14 — 2026-11-04
+
+- `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.

 App and Runtime.
 
+- 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 pins `hy-memory==2.0.14`. Lite search is plain RAG over raw: the
+  App's lite search, CLI context search, `/api/v1/recall` and the Host Bridge
+  (`MemHub_recall`, context search) return every vector hit above the floor,
+  ranked by score, over active and shadow raws, so history pro already
+  processed is still found after switching to lite. The turn view no longer
+  drops a hit whose turns do not literally contain the query; it shows the
+  hit's closest turn instead. Pro and ultra raw search stays active-only.
+  Fixes every raw search failing in packaged builds since #316, which passed
+  `statuses` to an SDK (2.0.13) that did not accept it. The lite raw-turn
+  page also stops re-listing the whole raw layer on each poll when a live
+  session only adds new raws.
+- MemHub Core no longer stalls writes or freezes the App for tens of seconds
+  on a machine with a long live-sync history. Finished live-sync import jobs
+  are pruned to the newest 20 per source (at startup, in bounded batches, and
+  every 10 minutes); history imports and every unfinished job are kept. Job
+  lookups are filtered in SQL with new indexes (schema migration 63) instead
+  of reading the whole table. The durable write queue runs its claims,
+  settles and lease renewals on its own threads, so import work can no longer
+  starve a lease. Import abandon, resume and enqueue, and the file watcher's
+  path attribution, no longer touch the database or the disk on the event
+  loop, and the WAL cadence checkpoint runs on its own thread instead of on
+  the writer's. The write drain now restarts itself after an unexpected exit,
+  reports the failure with its stack, and shows `write_drain` /
+  `write_drain_error` in memory-processing and `memhub status`.
+- Model Center (#293, #295): Settings splits into 界面语言 / 记忆模式 /
+  模型配置 pages, with separate 记忆整理 (generation) and 记忆搜索
+  (embedding) lanes. Changing one lane sends only that lane's patch. An
+  embedding change shows the switch plan, confirmation, progress, cancel and
+  rollback, and the search model only changes after the rebuilt index is
+  verified. Model panels open inside the lane that launched them and close
+  only after Core confirms the profile is active (#310).
+- Lite keeps raw conversations (#297): lite raw writes are no longer stopped
+  by the "pause model sedimentation" switch, the memory page lists every
+  imported raw conversation by role (by turn since #316), and lite adds a
+  manual raw input (source `one-memory-manual`) that never calls a
+  generation model.
+- The home page follows the memory mode (#298): lite counts raw
+  conversations and previews the latest one; pro and ultra read memories.
+  Pro and ultra now require an active generation model, in both the mode
+  preview and the switch.
+- Onboarding (#304) asks for lite or pro and resumes after a restart (schema
+  migration 62); pro finishes only once a generation model is active.
+- Smaller App fixes: compact home status copy (#307), clearer mode-switch
+  effects (#312), Ultra topic nodes are hover-only (#315), and settings
+  controls use the content width (#317).

+"""MemHub's raw search against the hy-memory wheel it pins, not the repo source.
+
+The suite's pythonpath puts the repository root first, so `import hy_memory`
+in a test reads the repo's `hy_memory/`, which can be ahead of the pinned
+release. Search kwargs the release does not accept then pass every test and
+fail every raw search in a packaged build (a `statuses` argument did exactly
+that against 2.0.13). These tests run in a child interpreter started with
+`-I`, so `hy_memory` resolves to the wheel installed in the Core venv, and
+drive the real routes over a real lite SDK client with a deterministic local
+embedder (no model, no network, no ONNX assets).
