 # Changelog
 
+## Unreleased - Conversation management (UI API extension 1.6.0)
+
+- `assistant_conversation` is open to every assistant user (`assistant.hasAccess` or `assistant.admin`, through the new `AssistantAccessPermissionChecker`) in the standard table UI. Rows stay locked to their owner by the `userId` record lock, so a user only ever sees, updates and deletes their own conversations; admins with the all-access key still see everyone's. The Assistant app (its nav) and every other assistant table stay admin-only.
+- Users change only a conversation's title, pinned flag and status (Active / Archived) through the table; the other fields are the assistant's own. A new title is encrypted in HIPAA mode, including literal text beginning with `enc:v1:`. Only an exact match to the same record's stored ciphertext is preserved unchanged; internal SYSTEM writes retain their existing storage path.
+- A table delete of a conversation also deletes its messages, turns, turn events, tool calls, feedback, data audits and pending actions (the same rows `DELETE /conversations/{id}` removes), so nothing is orphaned on a database without the cascading foreign keys. A conversation with an answer in progress is refused.
+- New record actions on `assistant_conversation`: **Archive conversations**, **Restore conversations** and **Delete conversations** (standard streamed ETL: selected records, Review, Result; same permission as the table; only rows the user can see; delete skips conversations with an answer in progress).
+- UI API extension assistant 1.6.0: `GET /conversations` items have `running` (an answer in progress: a RUNNING or CANCELLING turn that is not orphaned); `PATCH /conversations/{id}` accepts `{"read": true}` (sets `unreadCount` to 0); `GET /config` has `conversationsTable: "assistant_conversation"` when the session may query that table.
+
+## Unreleased - Starter prompts follow access
+
+- `profile.starterPrompts` in `GET /assistant/config` is built per user: up to three prompts generated from tables the user can read that have rows (UI API metadata and count as the user, bounded, current access rechecked on every request, stable order for the day), plus configured prompts only when tagged with tables the user can read (`[table] prompt`, `[none] prompt`; untagged lines are dropped). See UPGRADE.md.
+
+## Unreleased - Chat turns are not jobs
+
+- Ordinary chat turns no longer create core tracking jobs: they stay out of the Jobs tray and Jobs tables, and core no longer sends an "Assistant answer finished" notification for every answer. Crash safety is unchanged; it comes from the assistant's own turn table (leased, heartbeated `assistant_turn` rows, seq-numbered `assistant_turn_event` replay and the abandoned-turn sweep). The panel's Stop (`POST /turns/{id}/cancel`) is unchanged.
+- Removed the `AssistantRunTracker` SPI, `JobTrackingRunTracker` and `AssistantQBitConfig.withRunTracker` / `setRunTracker` / `getRunTracker` (see UPGRADE.md).
+- Real multi-step work stays a real job: a confirmed bulk load still launches through `POST /qqq/v1/processes/{p}/jobs`, and its tool result now carries `jobHref` (the job's `/app` link) next to `jobId`, plus a record ref to the job; the confirm response's `href` links to the job.
+- Scheduled task notifications (output mode Notification or Both) now go through core `QAlerts.notify` (category Job, the owner as the only audience, a link to the conversation, success/error/warning severity by run status), replacing the reflective call into an older alerts SPI that no longer matched.
+
+## Unreleased - Attachments
+
+- Files attached in the panel (`pageContext.attachments`, core upload refs) are read for the question: as the signed-in user's own upload, in memory, with per-file and per-question byte and character caps (`AssistantQBitConfig.attachments`). The type is sniffed from content; executables, archives and unknown binary data are refused. Text, Markdown and JSON are decoded with charset detection, PDF page text is extracted (PDFBox via QQQ core, no scripts, host font mapper preserved), CSV/TSV/XLSX become a header + rows + count preview, and PNG/JPEG/GIF/WebP images go to vision models as image parts.
+- Images are decoded with ImageIO before provider submission, rejecting truncated data and decoder warnings. A 16-million aggregate pixel / 100-frame budget bounds decoded data; original bytes are forwarded. WebP uses the explicit TwelveMonkeys decoder.
+- Content reaches the model in an untrusted `uploaded_file` block (delimiters neutralized) in the question's user message; the system prompt says it is data, never instructions. A file that cannot be read adds a notice to the answer and never fails the turn. In HIPAA mode attachments count as PHI.
+- Provider SPI: `ModelPart.Type.IMAGE` (`mediaType`, base64 `data`), mapped by the Anthropic, Bedrock and OpenAI-compatible providers. Claude models report vision. `ModelPart.toString()` never includes text or image data.
+- `GET /config`: `features.attachments`, `limits.maxAttachmentBytes`, `limits.maxAttachments`, `limits.attachmentTypes`.
+- System prompt: when `create_record` / `update_record` are offered, the model proposes the change instead of saying it cannot create records.
+
+## Unreleased - Optional provider health
+
+- An enabled provider that is not the default and not the only route for any configured routing (an enabled profile's simple/complex model, a budget downgrade model or a knowledge source's embedding model, with no fallback on another usable provider) is optional: when it is unreachable, its `assistant.provider.<id>` and `assistant.model.<id>` checks report DEGRADED with a message naming the provider requests use instead, so one unfinished local server no longer turns the whole `assistant` component DOWN. The default provider and sole routes still report DOWN. A failed provider probe still carries `reachable=false`, so the circuit breaker keeps refusing the provider.
+- New `assistant_provider.setup_state` (Setup state: Active / Setting up, empty counts as Active). A provider that is Setting up is never routed to (default, profile models, fallbacks, budget downgrades, embeddings) and gets no provider or model health checks; Test connection and Discover models still work. Apply the Provider setup state DDL (UPGRADE.md).
+
+## Unreleased - Fail soft (UI API extension 1.5.0)
+
+- Every message part, tool render and presentation is validated before it is stored or streamed, and again when stored parts and events are read: all render types (records, record, count, widget, history, pending_action, bulk_load_dry_run) and presentation blocks always carry their lists. A render that cannot be repaired is replaced by an error notice ("This result could not be displayed."); unknown part and render types pass through. Problems are logged with the type and a fixed code only.
+- Tool calls have their own limit (`toolCallTimeoutSeconds`, default 60) besides the turn's (`maxTurnSeconds`, default 300). A timed-out or failing tool gets an ERROR (`is_error`) result for the model, an ERROR tool part and an error notice for the user; internal details go only to the log.
+- Every turn ends: terminal events are emitted independently, so a failing emit never skips `message.end` or the terminal turn row. Conversation detail repairs assistant messages left `STREAMING` (an orphaned run is reaped; a run that already ended gives its status), and the retention process finalizes runs still `RUNNING` past the hard stream limit (e.g. after a pod restart).
+- `POST /qqq/v1/assistant/client-errors` (extension 1.5.0): the panel reports errors it hit (`scope`, `message`, optional stacks, route, ids, part/render type, app version, `occurredAt`). Answers `202 {"accepted": true}`; over `clientErrorsPerUserPerMinute` (default 30) it answers `202 {"accepted": false}` and drops the report. Fields are bounded, message and stacks scrubbed (secrets, e-mails, long numbers, tokens, query strings), ids kept only when they are the user's own. Rows go to the new owner-locked `assistant_client_error` table (Assistant app nav, retention after `toolResultRetentionDays`), and the `assistant.client-errors` health check turns degraded at `clientErrorWarnPerHour` (default 20) reports in an hour. Apply the Fail soft DDL (UPGRADE.md).
+
+## Unreleased - Empty renders and stream context (UI API extension 1.4.0)
+
+- Tool result renders always carry their lists: a `records` render for a query that matched nothing now has `"rows": []` and `"columns": []` (QQQ's JSON omitted empty lists, and Next's Assistant crashed the page reading `rows.length`). Parts and events stored before the fix are completed when read. Extension 1.4.0 documents the shape as `AssistantRecordsRenderV1`.
+- Streamed text arrives on the provider's own (virtual) thread; the turn's progress updates now run in the turn's QContext, so job progress no longer fails with "Could not flush job progress" (NPE on the missing instance).
+
+## Unreleased - UI API 1.6.0
+
+- UI API extension assistant 1.3.0 (requires QQQ 4.1.0-RC.15, UI API 1.6.0): operationIds, standard error responses with BasicErrorResponseV1, extension tags and trace IDs. Preserve HTTP statuses and assistant-specific error codes.
+- Retain AssistantErrorV1 as a deprecated component for compatibility. Remove dangling `null` schema references from the two bodyless 204 responses (delete conversation and feedback), with an empty-content workaround for core schema traversal. Success payloads are unchanged; the contract test retains the release baseline with explicit exceptions for the error schema migration and these documentation corrections.
+
+## Unreleased - Central health
+
+### Added
+
+- Dynamic `assistant.provider.<id>` and `assistant.model.<id>` dependency checks in component `assistant`, category AI, reusing provider diagnostics and minimal connection calls with deadlines, cost-cap/kill-switch skips and TEST usage accounting.
+- LOCAL breaker reuse of central provider outcomes younger than 60 seconds, with its existing lazy probe as fallback.
+- Generic Assistant health status card linking to filtered System Health; registration, status, accounting, deadline and sentinel-secret tests.
+- QQQ 4.1 compatibility for the header shim: setting extra headers avoids duplicates now that core forwards them too.
+
+### Removed
+
+- The home's independent answering/last-test health indicators and per-provider health/down-until display. Central health owns status and history. Manual Test connection actions, `lastTest*` fields and the circuit breaker remain.
+
+## Unreleased - Jobs tray
+
+- Track assistant answers in the core Jobs tray through `JobTracking`, with thinking, tool and writing progress and Stop support.
+- Require QQQ 4.1.0-RC.8 and the host's durable jobs runtime and jobs tables; answers remain untracked when the runtime is absent.
+- Default to `JobTrackingRunTracker`; opt out with `withRunTracker(AssistantRunTracker.NOOP)`.
+
+## Unreleased - In-app help
+
+- Ship the host-neutral Assistant help bundle through QQQ's native registry, replacing the temporary loader.
+- Cover Assistant tables, fields, actions, widgets and selectors; retain live metadata references and add a bundle coverage gate.
+- Document HOST bundle overrides and remove deployment-specific provider, classification, retention and backup guidance.
+
+## Unreleased - Transcript redaction
+
+- Tokenize classified PII/PHI in stored messages, tool inputs/results, replay events, pending actions and derived summaries using QQQ secured-data tokens. Preserve eligible model requests and live SSE.
+- Stage content until turn completion, redact split deltas and classify criteria even when no records match; protect assistant logs with a scoped core redactor.
+- Reject proposals whose parameters were redacted; prevent confirmation before turn completion.
+- Read core table-level classification metadata and add secured-data canary tests for storage, audits, logs and in-memory model access.
+- Preserve durable-turn watchdog, supersede, shutdown and restart recovery with turn-scoped transcript redaction; widen token-bearing columns and entity limits, with H2-safe upgrade SQL.
+- Require QQQ 4.1.0-RC.7 (qqq#1182); retain the default audit-history opt-in and avoid duplicated routing headers against current core. RC.7 is released.
+## 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 nullable `audit.client_channel VARCHAR(100)` using the host's migration and

+under `changesets/features/`; this QBit does not migrate the host's audit table.

Result has one line per provider: `connected to claude-sonnet-5-5 in 812 ms`, or the error with its kind and HTTP status. It makes one short live call (a 1-sentence prompt, at most 32 output tokens, effort low), saves the result on the row, and records the call in `assistant_usage` with purpose `TEST`.

+
+Suppliers include enabled provider/model rows and refresh with the central registry.
+Provider checks reuse `AssistantProviderType.checkHealth`. Unsupported probes use

+Model checks reuse `ConnectionTest` (embeddings for embedding models), respect the
+provider's monthly cost cap and the kill switch, and leave manual `lastTest*` fields
+unchanged. A capped check returns UNKNOWN, `skipped: cost cap`, even on demand.
+The automated runner records usage under its own owner key. Provider caps use the
+existing shared accounting projection without access to other users' usage records.
+Usage purpose is a string, so health diagnostics reuse `TEST` (not a new `HEALTH` enum).
+All checks honor their deadlines; messages and details omit provider error text,
+credentials, endpoints, prompts and completions.
+
+The LOCAL circuit breaker consults central results less than 60 seconds old before
+its lazy probe. UP/DEGRADED avoids a duplicate probe, DOWN rejects the call, and
+UNKNOWN or stale/missing results retain the existing probe fallback. The breaker

+
+Core's default `ClientChannelsMetaData` denies `audit*` to the `assistant`
+channel. Accordingly, `get_record_history` is offered only when all three audit
+tables it queries (`auditTable`, `audit`, and `auditDetail`) exist and are not
+channel-denied, including their effective permission rules. A host that intends
+to expose record history can opt in during instance configuration:
+
+```java
+new AssistantQBitConfig()
+   .withRecordHistory(true);
+```
+
+This is an owner decision and a hard wall: record history defaults to disabled;
+**kof22 does not opt in**. On QQQ RC.6, the opt-in removes exactly `audit*`
+from the assistant's denied patterns (the former manual configuration step).
+RC.6 does not add a separate channel write denial for audits. On later RCs that
+include QRun-IO/qqq#1193, it calls `withAssistantAuditReads()`, which allows audit
+reads but denies audit writes. The user's own audit permissions still apply.
+Other patterns, including `worm_audit_*`, `assistant_*`, and security surfaces,
+remain untouched, as do explicit object and permission-rule denials.
+
+History visibility uses core's `isDenied` read/all-operation check. RC.6 has no
+operation argument; the later write-only deny patterns must remain separate
+from that check so they do not hide the read tool.

 # Upgrading qbit-assistant
 
+## Conversation management (Unreleased, UI API extension assistant 1.6.0)
+
+No schema change. `assistant_conversation` is now usable by every user holding
+`assistant.hasAccess` (not only `assistant.admin`), together with three new
+record actions (Archive, Restore and Delete conversations). Rows stay locked to
+their owner. A user's table queries only return their own rows if their session
+carries their owner key: call `AssistantSecurity.applySessionKeys` from the
+authentication customizer for **every** user, not only for admins. Without it,
+non-admin users see an empty table.
+
+The panel can link to the table using `conversationsTable` from `GET /config`.
+That field is present only when the user may query the table.
+
+## Starter prompts follow the user's access (Unreleased)
+
+`GET /assistant/config` no longer returns the profile's starter prompts as written.
+`profile.starterPrompts` (same field, still `string[]`) is now built per user:
+
+- Up to three prompts are generated from the tables the signed-in user can read
+  through the assistant and that have rows (a count as the user), using the table
+  labels, a date field when present, and "What changed in ... this week?" when the
+  change-history tool is offered. The pick is stable for the user for the day and
+  rechecked on every request, including table, row and field access. Generation
+  uses bounded UI API calls and no model calls. Any failure yields no generated prompts.
+- A configured starter prompt (Assistant Profile > Starter prompts, one per line) is
+  shown only when it declares the tables it needs and the user can read all of
+  them. Declare them with a leading tag: `[blog_post] Which posts are drafts?`, or
+  `[blog_post, page] ...` for several. `[none] What can you help with?` names no
+  table and is always shown. A line without a tag is no longer shown, because
+  nothing says which tables it mentions: add a tag to keep it.
+- Shown prompts are the permitted configured ones first, then generated ones, three
+  in all (a profile with three or more permitted prompts shows only those).
+
+No schema change and no configuration. The panel needs no change.
+
+## Chat turns are not jobs (Unreleased)
+
+Ordinary chat turns no longer create core tracking jobs, so they no longer appear
+in the Jobs tray or the Jobs tables and no longer trigger a per-answer "finished"
+notification. No schema change and no configuration is needed.
+
+The `AssistantRunTracker` SPI and `JobTrackingRunTracker` are removed, along with
+`AssistantQBitConfig.withRunTracker`, `setRunTracker` and `getRunTracker`. A host
+that called any of them must delete the call: `withRunTracker(AssistantRunTracker.NOOP)`
+is now the only behavior, and a custom tracker has no replacement hook. Turn
+progress, Stop and recovery are available through the assistant's own routes
+(`GET /turns/active`, the turn events stream and `POST /turns/{id}/cancel`).
+
+Bulk loads the assistant launches are still durable jobs. Their confirmed tool
+result now includes `jobHref` (the job's in-app link) and the confirm response's
+`href` points at the job.
+
+Scheduled task notifications now use core `QAlerts.notify`; they reach whatever
+alerts sink the host installed (or core's logging sink when none is).
+
+## Provider setup state (Unreleased)
+
+Apply the **Provider setup state** block at the end of `docs/schema-postgres.sql`
+**before** deploying: the provider table now reads `setup_state`, so the new jar
+fails on `assistant_provider` without it. It adds a nullable `VARCHAR(16)` with
+default `'ACTIVE'` and a check for `ACTIVE` / `SETTING_UP`; existing rows behave as
+before. It is `IF NOT EXISTS` and safe to re-run.
+
+To stop an unfinished provider from being routed to or health-checked, edit it in
+Assistant > Assistant Provider (Provider section) and set **Setup state** to **Setting up** (SQL:
+`UPDATE assistant_provider SET setup_state = 'SETTING_UP' WHERE id = <id>;`).
+Enabled providers that are neither the default nor the only route for a configured
+model now report DEGRADED, not DOWN, when unreachable. No configuration change.
+
+## Fail soft (Unreleased, UI API extension assistant 1.5.0)
+
+Apply the **Fail soft** block at the end of `docs/schema-postgres.sql` before
+deploying. It creates `assistant_client_error` (errors the panel reports through
+`POST /qqq/v1/assistant/client-errors`) with its indexes and `SET NULL` foreign keys
+to the conversation, message and turn. It is `IF NOT EXISTS` and safe to re-run.
+
+New configuration, all optional: `toolCallTimeoutSeconds` (default 60),
+`clientErrorsPerUserPerMinute` (default 30) and `clientErrorWarnPerHour` (default
+20, when the `assistant.client-errors` health check turns degraded). The new table
+is in the Assistant app's nav for administrators.
+
+## Transcript redaction (Unreleased)
+
+Apply the transcript-redaction column widening block in `docs/schema-postgres.sql`
+to existing databases. Stop reasons, request IDs, tool-call IDs, feedback/data-audit/
+budget-override reasons and scheduled-run summaries/errors now use `TEXT`; token
+expansion must not fail a write or truncate secured-data tokens. The corresponding
+entity field limits are removed, including pending-action and tool-result summaries.
+
+## Foreign keys (2026-10-14)
+
+Recommended: apply the "Foreign keys" block at the end of
+`docs/schema-postgres.sql` (after the index audit). It is guarded and safe to re-run.
+- Adds the missing foreign keys across the conversation tables, usage, data audit,
+  budget accounting and profile skills, with the indexes they need.
+- Detail rows of a conversation `CASCADE`; the message/turn cycle, usage and the data
+  audit use `SET NULL`, so usage keeps its cost rows when a conversation is deleted.
+- Usage, budget accounting and the data audit hold their provider (`NO ACTION`):
+  disable a provider with history instead of deleting it.
+- `assistant_model.provider_id` changes from `NO ACTION` to `CASCADE`
+  (constraint renamed `fk_assistant_model_provider`).
+- Rows that point at a missing parent are first copied to `qqq_fk_quarantine`
+  (created if absent), then nulled, or deleted for the `NOT NULL` profile-skill
+  links. Check that table after the upgrade.
+
+No code change.
+
+## Index audit (2026-10-14)
+
+Recommended, not required: apply the "Index audit" block at the end of
+`docs/schema-postgres.sql`. It adds six indexes, every one `IF NOT EXISTS`:
+- 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.
+
+`JobTrackingRunTracker` is now the default `AssistantRunTracker`, using core
+`JobTracking` in QQQ **4.1.0-RC.8** to publish answers in the Jobs tray. The host
+must provide the jobs tables (through qbit-jobs / core `DurableJobsMetaDataProvider`)
+and run `DurableJobsRuntime`. Without that runtime, answers complete normally
+and are simply not tracked.
+
+Each job is owned by the assistant user, links to its `assistant_conversation`,
+and reports thinking, tool and writing phases. Tool progress contains only the
+tool label; terminal messages are fixed and never contain prompts or answers.
+The tray's Stop cancels the assistant turn. All tracker callbacks remain isolated
+from turn execution. Opt out with `withRunTracker(AssistantRunTracker.NOOP)`;
+hosts may still supply their own `AssistantRunTracker`.
+
+## Starter defaults, setup card and table help
+
+The jar now ships `db/liquibase/qbit-assistant/assistant-defaults.changelog.sql`.
+Include it from the host's master changelog **after** the changesets that create
+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
+Liquibase 4.x or later (preconditions are `sql-check`s).
+
+No DDL changes. New: the Assistant home's Setup card, the `assistant_data_access`
+table action **Add rows for every table** (`assistantDataAccessAddDefaults`,
+admin only) and bundle help on every assistant table (`help/qbit-assistant.yaml`).
+
+## X1/Y1: channel wall and audit attribution
+
+Requires QQQ 4.1.0-RC.6. Every assistant table, process, report and widget is
+explicitly denied to channel `assistant`; startup rejects an exposed object.
+Host customizations must preserve these denials. Administration uses `next-ui`.
+
+Before enabling `AuditsMetaDataProvider.withClientChannelField(true)`, add the
+nullable `audit.client_channel VARCHAR(100)` column using the host migration
+conventions. kof22 needs a feature changeset under `changesets/features/` (for
+example `2026-10-14-audit-client-channel.sql`); no host migration is applied here.
+Existing audit rows remain null. The test fixture enables the field.
+
+The existing `assistant_tool_call.auditHref` column now points to audit rows
+filtered by record, table and client channel, including for deletes. It is empty
+when the host has not enabled the audit channel field. Apply the X1/Y1 DDL in
+`docs/schema-postgres.sql` to widen the existing `assistant_tool_call.audit_href`
+column to TEXT: encoded filters with long table names or string record ids can
+exceed the old 500-character limit. No new QBit column is required. `GET /assistant/access` accepts an optional owned `turnId` for attribution.
+

+--   (like assistant_turn.provider_id): disable a provider with history, do not delete

+-- * assistant_budget_usage.usage_id has no foreign key on purpose: the projection
