test(defaults): keep the reference DDL's DO $$ block whole and skip it on H2

The foreign-key block is PL/pgSQL; the H2 loader in AssistantDefaultsChangelogTest now splits it as one statement and skips it. SchemaForeignKeyPostgresTest runs it on real Postgres. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

 # Changelog

+## 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+  `message.start.startedAt`, cancelReason `SUPERSEDED`.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.
+||||||| befb90a
+
+## 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.

+- Switch scheduled-result email delivery to qbit-email 0.1.0-RC.2's published `com.kingsrook.qbits.email.api` package, preserving templates, categories, idempotency keys, linked records and status mapping.
 - Add optional qbit-email 0.1.0-RC.1 delivery of a scheduled task's result (`AssistantEmail.sendScheduledResult`): template `assistant_scheduled_result`, link-only secure message for results above PUBLIC using core's `DataClassification`, owner-recipient hook, opt-in and `emailExternalApproved` gates.

 # Upgrading qbit-assistant

+## 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.
+
+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 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`).

+entries:
+  - key: app:assistantAdmin;slot:help
+    summary: "Set up and watch the in-app assistant: providers, budgets, profiles, skills, data access and usage."
+    content: |
+      The Setup card on the home lists every part of the assistant with its status and the next step. A new installation starts with a default profile, four starter skills, a monthly budget, a policy row, Anthropic prices and a disabled example scheduled task. Add a provider to start answering.
+
+  - key: table:assistant_provider;slot:help
+    summary: "A model provider the assistant can call: its type, model, endpoint and the variable that holds its key."
+    content: |
+      **How rows get created:** an administrator adds one with New (pick the type and model, and name the environment variable that holds the API key; the key itself is never stored). The default provider answers questions; Test connection checks it and Discover models fills the model list.
+
+  - key: table:assistant_model;slot:help
+    summary: "The models each provider offers, with what they support and their prices."
+    content: |
+      **How rows get created:** Discover models on a provider adds them, or an administrator adds one by hand. Budgets, fallbacks, routing and knowledge sources pick models from this list. Embedding models are used only for knowledge sources.
+
+  - key: table:assistant_model_price;slot:help
+    summary: "List prices per provider type and model, used to work out what each call costs."
+    content: |
+      **How rows get created:** the qbit seeds the current Anthropic list prices; add a row for any other priced model. Every call's cost in Usage is computed from these prices, and cost budgets count that cost. A model with no price costs zero, which is right for local models.
+
+  - key: table:assistant_policy;slot:help
+    summary: "The single policy row: kill switch, write confirmation, PII redaction, tool list and row limits."
+    content: |
+      **How rows get created:** the qbit seeds one `default` row. Only the first row is used. Empty values fall back to the code configuration. Turn on the kill switch to stop every answer at once.
+
+  - key: table:assistant_budget;slot:help
+    summary: "Spending or token limits per instance, user, role, provider or model, with warn, downgrade and stop."
+    content: |
+      **How rows get created:** the qbit seeds a monthly budget for the whole instance ($50: warn at 80%, switch to the cheapest allowed model at 100%, stop at 120%). Add more for users, roles, providers or models. Every question is checked against every budget that applies before the model is called.
+
+  - key: table:assistant_budget_override;slot:help
+    summary: "A temporary raise or unlimited window for one budget, with a reason and an expiry."
+    content: |
+      **How rows get created:** an administrator adds one when a budget is reached and work must continue. Empty means no budget is currently raised. Overrides expire on their own.
+
+  - key: table:assistant_budget_event;slot:help
+    summary: "Each time a budget warned, downgraded or stopped someone, once per period and state."
+    content: |
+      **How rows get created:** written by the assistant when usage crosses a budget threshold; it also raises an alert. Empty means no budget has been reached yet.
+
+  - key: table:assistant_budget_usage;slot:help
+    summary: "Accounting copy of every call's tokens and cost, kept for shared budgets."
+    content: |
+      **How rows get created:** written with every model call. Instance, provider and model budgets add up these rows. Empty means the assistant has not answered anything yet.
+
+  - key: table:assistant_profile;slot:help
+    summary: "Who the assistant is in an app or for a role: name, tone, greeting, starter prompts and skills."
+    content: |
+      **How rows get created:** the qbit seeds a `default` profile that applies everywhere. Add a profile with an app name or a permission to change the assistant for that app or role; the most specific match wins. Profiles change tone and know-how only, never permissions.
+
+  - key: table:assistant_skill;slot:help
+    summary: "Know-how text the assistant follows when a question matches its keywords or app."
+    content: |
+      **How rows get created:** the qbit seeds four starter skills (finding and counting, explaining a record, safe changes, access questions). Write your own for your business terms. A skill reaches the model only when it is linked to a profile and the question matches its keywords or app; it never grants tools or data.
+
+  - key: table:assistant_profile_skill;slot:help
+    summary: "Which skills each profile offers to the model."
+    content: |
+      **How rows get created:** the qbit links the starter skills to the default profile. Add a row to offer a skill through another profile.
+
+  - key: table:assistant_data_access;slot:help
+    summary: "What the assistant may do with each table or process: NONE, READ or READ and write."
+    content: |
+      **How rows get created:** a table with no row gets the default: READ (or NONE for sensitive tables), always limited by the user's own permissions; processes default to NONE. Use **Add rows for every table** to write those defaults out as rows you can edit, then raise a table to READ_WRITE to let the assistant propose changes there.
+
+  - key: table:assistant_rag_source;slot:help
+    summary: "A table the assistant can search by meaning (knowledge source), with its fields and embedding model."
+    content: |
+      **How rows get created:** an administrator adds one: pick a table the assistant can read, its text fields and an enabled embedding model, then run Index knowledge source. The index keeps no record text; every hit is re-read as the asking user. Empty means search_knowledge is not offered.
+
+  - key: table:assistant_scheduled_task;slot:help
+    summary: "A question the assistant answers on a schedule as a chosen user, with the result saved or sent."
+    content: |
+      **How rows get created:** the qbit seeds a disabled example. To use it, set the run-as user, an allowed credential variable and the schedule, then turn it on. Scheduled writes always wait for the user's confirmation in the panel.
+
+  - key: table:assistant_scheduled_run;slot:help
+    summary: "One run of a scheduled task: when, status, cost and the conversation it produced."
+    content: |
+      **How rows get created:** written each time a scheduled task runs. Empty means no task has run yet; see Scheduled tasks.
+
+  - key: table:assistant_conversation;slot:help
+    summary: "One chat between a user and the assistant, from the panel or a scheduled task."
+    content: |
+      **How rows get created:** created when someone asks the assistant a question. Users see only their own; administrators see all. Retention removes old ones.
+
+  - key: table:assistant_message;slot:help
+    summary: "The messages of each conversation: questions, answers and tool results."
+    content: |
+      **How rows get created:** written as a conversation happens. Content is encrypted in HIPAA mode and removed by retention.
+
+  - key: table:assistant_turn;slot:help
+    summary: "One question and its answer: status, model, tokens, cost, timing and routing."
+    content: |
+      **How rows get created:** written for every question the assistant answers. Use it to see failures, slow answers and costly questions.
+
+  - key: table:assistant_turn_event;slot:help
+    summary: "The step-by-step event stream of each answer, for replay and troubleshooting."
+    content: |
+      **How rows get created:** written while an answer streams. Retention removes old events.
+
+  - key: table:assistant_tool_call;slot:help
+    summary: "Every tool the assistant called: which, with what input, the result status and timing."
+    content: |
+      **How rows get created:** written for each tool call during an answer. Denied calls show where data access or permissions stopped the assistant.
+
+  - key: table:assistant_pending_action;slot:help
+    summary: "A create, update or delete the assistant proposed, waiting for the user to confirm it."
+    content: |
+      **How rows get created:** written when the assistant proposes a change on a READ_WRITE table. It runs once, only after the user confirms it in the panel. Empty means no change has been proposed.
+
+  - key: table:assistant_feedback;slot:help
+    summary: "Thumbs up or down and comments users gave on answers."
+    content: |
+      **How rows get created:** written when a user rates an answer in the panel. Empty means nobody has rated an answer yet.
+
+  - key: table:assistant_usage;slot:help
+    summary: "One row per model call: tokens, cost, provider, model and purpose."
+    content: |
+      **How rows get created:** written with every model call, including connection tests. Costs come from Model prices.
+
+  - key: table:assistant_usage_daily;slot:help
+    summary: "Daily token and cost totals per user and for the instance, for the configured limits."
+    content: |
+      **How rows get created:** updated after every answer. The policy's daily and monthly limits read these totals.
+
+  - key: table:assistant_data_audit;slot:help
+    summary: "Where data went: which provider and model received which tables' data, with its classification."
+    content: |
+      **How rows get created:** written before each model or embedding call that carries application data. Use it to show that sensitive data went only to allowed providers.

james.maesandClaude Opus 5.5	1bae6e26ba	test(defaults): keep the reference DDL's DO $$ block whole and skip it on H2 The foreign-key block is PL/pgSQL; the H2 loader in AssistantDefaultsChangelogTest now splits it as one statement and skips it. SchemaForeignKeyPostgresTest runs it on real Postgres. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-14 17:55:19 -05:00
james.maesandClaude Opus 5.5	80d529e741	Merge feature/schema-indexes (with origin/develop) into feature/foreign-keys Conflicts in CHANGELOG.md and qbit-assistant/pom.xml: kept develop's durable-turns and starter-defaults entries and its H2/Liquibase test dependencies alongside the Testcontainers/Postgres ones.

james.maesandClaude Opus 5.5	b50bc4a5c7	Merge origin/develop into feature/schema-indexes Conflicts in UPGRADE.md and docs/schema-postgres.sql: kept develop's durable-turns and starter-defaults notes and DDL; the index audit block now follows the durable-turns block at the end of the schema.

james.maes	6a1bac6a9e	Merge pull request #52 from QRun-IO/fix/assistant-defaults-rollback fix(defaults): empty rollbacks; a rollback never deletes host data	2026-10-14 17:12:49 -05:00
james.maesandClaude Opus 5.5	9c3af04a91	fix(defaults): empty rollbacks so a rollback never deletes host data A seeded row cannot be told apart from a host's own row with the same name ('default' profile, policy, starter skill names), and Liquibase also rolls back changesets it marked ran, so the name-based rollback lines could delete a host's data. Every seed changeset now rolls back to nothing; the test runs a real Liquibase rollback over host-owned rows and checks they survive.

james.maesandClaude Opus 5.5	ba8e7a6562	fix(defaults): portable preconditions; never change an existing host on deploy Review of #48 found: - the formatted-SQL table-exists precondition does not parse in Liquibase 5 (and is unsupported in 4.19), failing the host's whole migration: use sql-checks only; - the budget and prices were seeded beside a host's own budgets and over its configured pricing: seed the policy, budget and prices only into empty tables, the profile only when no default profile exists; - the Setup card ignored registry and configured prices: price the default model exactly as calls are costed; - "Add rows for every table" could read a stale data-access cache. The changelog test now runs through Liquibase 4.33 (kof22's version): fresh schema, re-run, an already configured host, and a missing table.

james.maesandClaude Opus 5.5	50898a927d	test(turns): completion, error after streaming, disconnect, refresh, supersede, concurrency, wedged provider, pod kill, rolling deploy, cross-pod Stop Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-14 16:36:42 -05:00
james.maesandClaude Opus 5.5	f60009f595	feat(api): never refuse a question; cross-pod Stop; GET /turns/active A new question supersedes the running one in the conversation (default) or runs concurrently; the soft per-user cap supersedes the oldest. Stop works on any replica and on dead runs, and is idempotent. Orphans are reaped once their lease lapses (45 s) instead of after maxTurnSeconds + 60 s. 503 SHUTTING_DOWN while a replica stops. turn.phase events and startedAt on message.start. UI API extension assistant 1.2.0. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-14 16:36:41 -05:00
james.maesandClaude Opus 5.5	ffa7e25bf4	fix(turns): every turn is finalised: watchdog, lease, hard deadline, shutdown A per-turn watchdog (the user's own session) renews the lease, picks up a Stop requested on another replica, enforces maxTurnSeconds and force- finalises a wedged engine. One idempotent finaliser: accounting or event failures can no longer leave a turn RUNNING or registered. On shutdown the runtime stops taking turns, cancels, waits a grace and finalises the rest as interrupted. The in-memory concurrent counter is gone. Runs are published through the AssistantRunTracker stand-in SPI (qqq#1210). Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>	2026-10-14 16:36:41 -05:00

james.maesandClaude Opus 5.5	a5c38d74a8	feat: starter defaults, setup card and table help so no config table starts empty Owner requirement 2026-10-14: every assistant table should be populated and visibly used, and an empty table should say how to set it up. - db/liquibase/qbit-assistant/assistant-defaults.changelog.sql (host-included, insert-only, self-guarding): default policy, default profile, four starter skills linked to it, a $50/month instance budget (warn 80, downgrade 100, stop 120), current Anthropic prices, a disabled example scheduled task. - Assistant home Setup card: each config table, its state and the next step. - assistant_data_access action "Add rows for every table" writes the default access out as editable rows. - help/qbit-assistant.yaml (help-bundle format) on the app and every table, saying what it is for and how rows get created (STAND-IN(core=#1198)). - Tests: guardrail (every table used at runtime, seeded or explained, with empty-state help); changelog seeds a fresh H2 schema insert-only; seeded rows drive persona, skills in the model request, budget warning, policy.

james.maesandClaude Opus 5.5	fdf8d72367	feat(schema): add the missing foreign keys with orphan quarantine Reference DDL gains a guarded, re-runnable foreign key block after the index audit: the conversation tree CASCADEs (matching AssistantStore.deleteConversation and retention), the message/turn cycle, usage and the data audit are SET NULL so cost rows and the audit trail survive, provider references from usage, budget accounting and the data audit are NO ACTION, profile-skill links CASCADE, and assistant_model.provider_id becomes CASCADE (fk_assistant_model_provider, as on kof22). Orphans are recorded in qqq_fk_quarantine first. Every FK column now leads an index. SchemaForeignKeyPostgresTest applies the DDL on Postgres (Testcontainers) and fails any declared relation without a foreign key, a wrong delete rule, an unindexed FK column, or a broken conversation delete order.

james.maesandClaude Opus 5.5	8aac6cf92d	docs(schema): add the missing lookup, retention and FK indexes The reference Postgres schema gains six IF NOT EXISTS indexes: - assistant_usage (turn_id): ScheduledTurn.cost - assistant_turn_event (create_date), assistant_tool_call (create_date) and assistant_conversation (modify_date): the retention filters - assistant_scheduled_run (conversation_id) and (turn_id): the ON DELETE SET NULL foreign keys UPGRADE.md notes them.

james.maesandClaude Opus 5.5	8655ea21d4	refactor!: provider SPI in its own package com.kingsrook.qbits.assistant.spi The qbit-assistant-provider-api artifact now holds exactly one package, com.kingsrook.qbits.assistant.spi (23 types including ModelPricing), so consumers such as qbit-marketing depend only on that artifact and the qbit-bom G1 guardrails can allow it by package. BREAKING: imports change from ...assistant.provider.X / ...assistant.engine.ModelPricing to ...assistant.spi.X (UPGRADE.md has the table).
