 # Changelog
 
-### Changed: W1 core Preferences (F13 / #29)
-- Replace the bespoke assistant preferences operations with the core `assistant`
-  section at `/qqq/v1/preferences/assistant`, backed by the existing visible table.
-  User ownership, partial updates, policy validation, read-only explanations and
-  explicit assistant-channel denial apply to the section.
-- Keep effective defaults on `/assistant/config`; preserve Read-only/Write tools,
-  low-risk auto-confirm, develop's core invoker, provider routing and audit context.
-- Require per-task approval and Write-mode policy for scheduled writes; gate bulk
-  write definitions and calls by mode. Preserve default-off audit history on core develop.
-- Target QQQ 4.1.0-RC.8; use the local PREFS snapshot override until publication.
+## Unreleased - Foreign keys
 
+- Reference DDL: add the missing foreign keys (conversation tree, usage, data audit,
+  budget accounting, profile skills) with orphan quarantine and their indexes; make
+  `assistant_model.provider_id` `ON DELETE CASCADE`. A Postgres guardrail test fails
+  any declared relation without a foreign key.
+
+## Unreleased - Durable turns
+
+- Renew user-owned run leases with heartbeats, poll cross-replica Stop, enforce
+  hard deadlines, and finalize active runs during graceful shutdown. Recover
+  abandoned runs on replay, active discovery, or the next question.
+- Default to superseding a prior answer in the same conversation. Accept explicit
+  concurrent questions; the per-user cap supersedes the oldest run instead of
+  refusing another question. Per-minute limits and budgets still apply.
+- Add `GET /qqq/v1/assistant/turns/active`, `turn.phase` progress and `startedAt`
+  on `message.start`. Cancel is idempotent and returns HTTP 200.
+- Add the optional `AssistantRunTracker` Jobs tray SPI (no-op by default),
+  pending QQQ core job tracking (#1210).
+- Add the durable-turn schema upgrade; apply it before deploying this runtime.
+  A partial unique index fences duplicate terminal events from concurrent reapers.
+- UI API extension `assistant` 1.2.0 (additive): `turns/active`, the optional
+  `concurrency` on a new turn, 503 `SHUTTING_DOWN`, `turn.phase`,
+  `message.start.startedAt`, cancelReason `SUPERSEDED`. The 429 response stays
+  documented for budgets and per-minute limits; the "answer already in progress"
+  refusal is no longer returned. Cancel keeps 202 documented for older replicas.

+## Unreleased - Starter defaults
+
+- Every seed changeset's rollback is empty: a seeded row cannot be told apart from a host's own row with the same name, and Liquibase also rolls back changesets it marked ran, so a name-based undo would delete host data.
+
+- Fix the defaults changelog: every precondition is a portable `sql-check` (the formatted-SQL `table-exists` form failed to parse); the policy, budget and prices are seeded only into empty tables and the profile only when no default exists, so an existing host never changes on deploy. The test now runs the changelog through Liquibase 4.33, including an already configured host and a missing table.
+- The Setup card prices the default model the way calls are costed (registry, price rows, configured prices); "Add rows for every table" reads fresh data-access rows.
+
+- Ship `db/liquibase/qbit-assistant/assistant-defaults.changelog.sql`: insert-only starter rows for the policy, a default profile, four starter skills offered through it, a monthly instance budget (warn, downgrade, stop), current Anthropic prices and a disabled example scheduled task.
+- Add the Setup card to the Assistant home: every configuration table with its state (set up, needs setup, using defaults, optional) and the next step.
+- Add the `assistant_data_access` table action "Add rows for every table", which writes the default access out as editable rows.
+- Add `help/qbit-assistant.yaml` (QQQ help-bundle format) for the app and every assistant table, saying what each table is for and how its rows get created; applied by `AssistantHelp` until core help bundles ship in a release.
+- Guardrail tests: every table is used at runtime, seeded or explained, and has empty-state help; the changelog seeds a fresh schema and the seeded rows change the assistant's behavior.

-
-Write tools, including bulk profile saves and bulk loads, are absent in Read-only
-mode. Write mode requires policy permission and READ_WRITE data access. Low-risk
-auto-confirm is limited to single-record inserts/updates on `auto_confirm_ok`

-by `assistant.hasAccess`, not the admin-only Assistant app. The provider explicitly

+- usage by turn (read on each scheduled run)
+- the three retention date filters (turn events, tool calls, inactive conversations)
+- the two `ON DELETE SET NULL` foreign keys on `assistant_scheduled_run`
 
+No code change.
+
+## Durable turns (Unreleased)
+
+Apply the **Durable turns** block at the end of `docs/schema-postgres.sql` before
+starting the new runtime. It adds nullable `heartbeat_at`, `lease_owner`,
+`cancel_requested_at`, `phase`, `concurrency_mode` and the `(user_id, status)`
+index. A partial unique index on terminal events also prevents two replicas from
+inserting separate `message.end` frames for the same turn. Check for historical
+duplicate terminal frames before applying it (resolve any duplicates through your
+normal migration process). Fresh installs run the full schema, including ALTERs.
+Existing rows with no heartbeat use `started_at` for lease expiry. During the
+first upgrade from a runtime without heartbeats, drain old replicas' turns first:
+a new replica cannot distinguish an old live turn from a dead owner after 45 s.
+
+Defaults: heartbeat 5 s, lease 45 s, hard duration 300 s, force-finalization grace
+20 s, shutdown grace 8 s. Configure these through the corresponding
+`AssistantQBitConfig` withers. Heartbeat must be shorter than the lease. The JVM
+shutdown hook is enabled by default; tests disable `registerShutdownHook` and
+managed hosts may call `runtime.shutdown(Duration)` themselves. Give the process
+termination budget enough time for the configured shutdown grace and persistence.
+
+`POST /conversations/{id}/turns` accepts `concurrency: "supersede" | "concurrent"`
+(case-insensitive). Default `SUPERSEDE` stops prior runs in that conversation;
+`CONCURRENT` permits them. The default per-user cap is now 3; reaching it stops
+the oldest run instead of returning the old in-progress 429. Per-minute and
+budget 429 responses still apply. Superseded turns record `cancelReason=SUPERSEDED`.
+
+Cancel now returns HTTP **200**, including for terminal turns, with the current
+`status`. The OpenAPI fragment retains the old 202 response for mixed-version
+rollouts. Active runs are discoverable through `GET /qqq/v1/assistant/turns/active`;
+reattach through the existing events route. Consumers should recognize
+`turn.phase` and `message.start.startedAt`. Starts during shutdown return
+503 `SHUTTING_DOWN`; clients may retry against a ready replica.
+
+Hosts may wire `AssistantRunTracker` for Jobs tray publication, progress, Stop,
+and terminal notification. It is a no-op by default and all callbacks are
+isolated from turn execution. Tracking ids are local to the owning runtime;
+reaping an already dead owner does not invent another tracking job. Hosts should
+associate their durable tracking row with the supplied turn id. The SPI is a
+stand-in for QQQ #1210.

+## Starter defaults, setup card and table help
+

+the `assistant_*` tables:
+
+```yaml
+- include: { file: db/liquibase/qbit-assistant/assistant-defaults.changelog.sql }

+
+It is insert-only and never changes a host that already configured the
+assistant: the policy, the **$50/month instance budget** (warn 80%, downgrade
+100%, stop 120%) and the Anthropic list prices are seeded only into empty tables,
+and the `default` profile only when no default profile exists. Price rows take
+precedence over `AssistantQBitConfig.withPricing`, which is why they are seeded
+only when there are none. The four starter skills and a disabled example
+scheduled task are always added (by name); on a host with its own default
+profile the skills are not linked to it, and the Setup card says so. Requires
