 # Changelog
 
+## Unreleased - P-g
+
+- Add admin Scheduled tasks, owner-locked run history, Quartz cron/timezones,
+  and a 60-second QQQ scheduled process using the host's scheduler context.
+- Log in through the loopback UI API with a separately allow-listed credential
+  environment reference; verify the designated user before starting a normal turn.
+- Add Review/Result Approve write mode, Revoke write mode and Run now actions.
+  Approval binds the task definition; scheduled writes always await confirmation.
+- Attribute scheduled UI API requests and tool logs, apply per-run STOP caps,
+  and send optional Alerts notifications to the designated user. HIPAA summaries
+  contain only `see conversation`.
+- Add unique schedule-slot claims, fixed-clock fixture integration tests and
+  additive Postgres DDL. No API routes or provider modules change.
+
+## Unreleased - P-f
+
+- Add OpenAI-compatible embeddings (including Azure), explicit CHAT/EMBEDDING
+  model kinds, editable discovery hints, and budgeted EMBED usage.
+- Add admin Knowledge sources with streamed Review/Result Index now and Clear
+  index actions. Indexing uses the clicking admin's UI API session, chunks text,
+  skips unchanged hashes and reconciles disappeared records.
+- Add content-free in-memory and optional JDBC pgvector stores, per-instance
+  schemas, HNSW cosine search and transactional record replacement.
+- Add permission-filtered `search_knowledge`, fresh UI API reads, existing
+  masking/redaction, PHI embedding guards, classification propagation and citations.
+- Add embedding HTTP contracts, real UI API RAG security/golden tests and
+  always-on JDBC contracts; the pgvector container test skips without Docker.

 ### Changed (0.1.0-RC.6): tools go through the UI API (owner decision 2026-10-13)
 - **Every data tool runs a spec'd `/qqq/v1` operation with the user's own session** (`UiApiGateway`, loopback HTTP with the `sessionUUID` cookie): the same authentication, permissions, record locks, validation, audit and errors as the UI. A user without a permission gets the identical denial through the assistant. `navigate` and `search_help` (no records) stay on the core kernel. `LoopbackUiApiGateway` is a stand-in for core's `UiApiInvoker` (QRun-IO/qqq#1128).

   - Never use `QSystemUserSession` or construct a `QSession` in main code (ArchUnit).
   - Every route uses `ExecutorSessionUtils.setupSession` (the user's own session).
   - `AssistantSecurity` only ever adds the user's OWN id key, or the all-access key for `assistant.admin` holders.
 - **Data access:**
+  - The vector index stores no record content: only source/table/key/field/chunk, content hash and embedding. Retrieval re-reads every hit through the UI API as the asking user, then applies the existing get_record exposure/masking path.
   - Only `persistence/` calls QueryAction, InsertAction and the other data actions (ArchUnit).
   - Data tools run only through `UiApiToolbox` → `UiApiGateway` (spec'd `/qqq/v1` operations with the user's `sessionUUID`); never core data actions for user data. Only `navigate` and `search_help` use `AiToolKernel.execute`.

+
+## RAG setup
+
+Knowledge retrieval is optional. The vector index stores **no record content**:
+only source/table/key/field/chunk identifiers, SHA-256 hashes and embeddings.
+Indexing reads through the UI API as the clicking administrator. Retrieval
+re-reads each hit through that same API as the asking user, silently filters
+403/404 results, applies `get_record` field exposure/masking/redaction and returns
+fresh snippets with `/app/...` citations. `search_knowledge` follows `allowedTools`
+and is offered only with an enabled source the user may read in the UI.
+
+1. Register the OpenAI-compatible provider module and configure the embedding
+   endpoint through the existing provider settings/URL allowlist. Discover or add
+   a model, set **Model kind = EMBEDDING** and its dimensions. Known discovery
+   defaults are `bge-m3` (1024) and `nomic-embed-text` (768); these remain editable.
+   CHAT models cannot be selected for embedding, and EMBEDDING models cannot answer
+   chat turns. Each embedding batch contains at most 64 inputs.
+2. Use the default `InMemoryVectorStore` for tests/small hosts, or add
+   `com.kingsrook.qbits:qbit-assistant-rag-pgvector` at the QBit's version for
+   persistence. The host supplies its JDBC driver and DataSource; this module
+   does not depend on QQQ RDBMS internals.
+3. For pgvector, have the DBA install the extension once in the chosen database:
+   `CREATE EXTENSION IF NOT EXISTS vector`. Give the application a distinct schema
+   per QQQ instance. Configure the store before producing the QBit:
+
+   ```java
+   PgVectorStore vectors = new PgVectorStore(dataSource, 1024)
+      .withSchema("assistant_rag_my_instance");
+   vectors.ensureSchema();
+   config.withVectorStore(vectors);
+   config.withUiApiBaseUrl("http://127.0.0.1:8000");
+   ```
+
+   The UI API URL is this server's own listening address. Configure it explicitly
+   so Index now works before any chat request has taught the runtime its local
+   port. The store creates a content-free `assistant_rag_chunk` table and an HNSW
+   cosine index. Its fixed dimension must match every source using the store;
+   different models are searched separately. No credentials go in source rows.
+   See the [pgvector installation/index documentation](https://github.com/pgvector/pgvector)
+   and the reference DDL in [schema-postgres.sql](docs/schema-postgres.sql).
+4. Open **Assistant → Knowledge sources** as an `assistant.admin`. Add the table,
+   comma-separated text fields, optional title field and QQQ query-filter JSON,
+   embedding model, and chunk size/overlap (defaults 1500/200). Tables with AI data
+   access NONE, `assistant_*` tables, and fields with NONE/METADATA_ONLY exposure
+   are refused. MASKED fields are masked before embedding and in snippets.
+5. Select **Index now**. Review makes no embedding calls; Result reports records
+   seen, chunks embedded, unchanged, removed and errors. Re-running unchanged
+   content sends no embeddings. A complete successful scan removes disappeared
+   records; failed scans preserve unvisited entries. **Clear index** removes only
+   that source's vectors. Changes after indexing are read fresh, but semantic
+   ranking becomes current only after re-indexing.
+
+Embedding usage has purpose `EMBED`, counts toward budgets, and observes the kill
+switch and provider concurrency limits. PHI sources and queries in PHI
+conversations require an eligible embedding provider; the eligibility flag is an
+operator assertion, as for chat. Automatic budget downgrades cannot change an
+embedding model's vector space, so an incompatible downgrade stops the call.
+
+Scheduling is deferred to P-g. Its designated-user runner can call
+`RagService.index` within that user's authenticated context; P-f creates no system
+session, stored admin credentials, scheduler or background content crawler.
 Data tools call the QQQ UI API through `UiApiToolbox` and `UiApiGateway` with the signed-in user's session. The UI enforces permissions and record security; the assistant further narrows access and caps and redacts returned values. Data tool results reach the model wrapped as untrusted data.

+

+   .withScheduledTasksSchedulerName("hostScheduler")
+   .withAllowedScheduledCredentialEnvNames(Set.of("ASSISTANT_SCHEDULED_TOKEN"));
+```
+
+Provide a long-lived access token accepted by the host's authentication provider
+in that environment variable. Store only its **name** on the task and set
+`runAsUserId` to the corresponding QQQ user id. The runner posts the token to
+`/qqq/v1/manageSession`, reads its session cookie and verifies the returned
+session's user before starting a new conversation. No system session reads user
+data. Configure the loopback URL at startup; a scheduled job cannot rely on a
+browser having visited first.
+
+For kof22, provision a designated Authentik account with the intended application
+permissions, obtain a token that kof22's QQQ authentication provider accepts as an
+`accessToken`, and inject it through the existing secret-manager/ExternalSecret
+pipeline. An Authentik management API token is suitable only if the host's auth
+adapter explicitly accepts it. Rotate the token in the secret manager, never in
+the task table. This feature does not provision an account or token.
+
+**Run now**, **Approve write mode** and **Revoke write mode** are Review/Result
+record actions. Write approval names the designated user and displays the exact
+prompt SHA-256. Changing prompt, user, credential reference, profile or write-mode
+request clears approval. Scheduled writes always wait for that user's panel
+confirmation, even if normal policy disables confirmation.
+
+Each run keeps an owner-locked audit row and a normal conversation. RECORD adds
+no notification; NOTIFICATION and BOTH also notify the designated user through
+the optional Alerts QBit SPI. Without Alerts, notification delivery is log-only.
+HIPAA summaries are always `see conversation`. Cost caps stop at dispatch
+boundaries, so the last completed call can cross the cap; no further call starts.

 # Upgrading qbit-assistant
 
+## P-g: scheduled tasks
+
+Apply the **P-g** DDL in [docs/schema-postgres.sql](docs/schema-postgres.sql)
+before deploying. The unique `(task_id, scheduled_for)` constraint is required
+for multi-replica safety; retain run rows as schedule-slot claim history.
+Existing conversations default to channel `panel`. Tasks start disabled.
+
+Set `withScheduledTasksSchedulerName(...)` to an existing QQQ scheduler and
+configure `withUiApiBaseUrl(...)` with this replica's own listener URL. The runner
+polls every 60 seconds. QQQ must supply a scheduler session able to manage the
+assistant tables; this QBit never creates that session. The configured backend
+must enforce unique keys atomically (Postgres does).
+
+Allow only designated credential references with
+`withAllowedScheduledCredentialEnvNames(Set.of("ASSISTANT_SCHEDULED_TOKEN"))`.
+Provide that variable through the host's secret manager. It must hold a token
+accepted by the host's `manageSession` authentication provider for `runAsUserId`.
+The runner fails closed on missing/disallowed credentials or an identity mismatch.
+See [scheduled-task setup](README.md#scheduled-tasks) for kof22 provisioning.
+
+QQQ RC.5 has no conditional UpdateInput. The runner uses a database-unique
+schedule-slot insertion as its optimistic claim, then advances `nextRunAt`
+before starting work. Crashes can skip a slot; they never retry it. No ArchUnit
+exception or fabricated session is introduced. Core client-channel enforcement
+arrives with the client-channel RC; the header and tool audit are already sent.
+
+Notifications use the optional Alerts QBit notification SPI with a single-user
+audience. Without it, delivery logs run id/status only. All output modes retain
+the owner-locked audit row and conversation. HIPAA run summaries never copy the
+answer; they contain only `see conversation`.
+
+## P-f: knowledge retrieval
+
+Apply the **P-f** assistant-table DDL in
+[docs/schema-postgres.sql](docs/schema-postgres.sql) before deployment. It adds
+`assistant_model.model_kind` (existing rows default to CHAT),
+`embedding_dimensions`, and the admin-only `assistant_rag_source` table.
+No sources are seeded. Existing chat selections remain unchanged; explicitly
+EMBEDDING models are excluded from chat, classifier, fallback and downgrade
+selection. Correct discovery's kind/dimensions if a model name is ambiguous.
+
+For persistent vectors, add `qbit-assistant-rag-pgvector` at the same version as
+the QBit, supply the host's JDBC DataSource/driver, and install pgvector in the
+database. A DBA runs `CREATE EXTENSION IF NOT EXISTS vector`; the application
+role needs schema creation rights for initial setup (or a DBA-created schema),
+then normal DML rights. `ensureSchema()` checks for an existing extension first
+and does not require extension installation privileges when it is already present.
+The optional pgvector DDL is a **commented reference block**, separate from the
+assistant-table migration. See [RAG setup](README.md#rag-setup).
+
+Use a distinct validated schema for each QQQ instance. `vector(N)` fixes dimensions
+for that store; changing dimensions requires a new schema and re-indexing.
+Sources can use different models with that dimension; ranking is restricted to
+sources using the query's model. If the weights behind an unchanged model id
+change, clear and rebuild its sources. Editing source chunk/filter/model settings
+or registry model identity/dimensions automatically clears affected vectors.
+
+Every indexing batch produces EMBED usage and updates existing budget rollups.
+PHI source content and PHI conversation queries require a HIPAA-eligible embedding
+provider. No background runner or designated credentials are installed in P-f.
+The default in-memory store is lost on restart and must be indexed again.

+- `KnowledgeTool` is separate from the unchanged `UiApiToolbox`. A small
+  ContextBuilder hook adds it only for an enabled source, policy permission and
+  UI-readable source table. Search embeds the question, requests 4× the result
+  limit, then re-reads each hit through get_record with the asking user's session.
+  403/404 hits contribute only to the filtered count. Safe current values produce
+  snippets and `/app` citations; record refs propagate touched tables into P-c
+  classification and the normal tool-call log. The citation instruction is in
+  the static rules block. The result limit is capped at eight.
+- PHI source content and PHI conversation queries only reach eligible embedding
+  providers. Embedding budgets, kill switch and provider concurrency checks apply
+  to each batch. A budget downgrade into another vector space stops embedding.
+- Tests exercise real fixture UI API reads, denials, record locks, field masking,
+  PHI refusal, classification, reconciliation, embedding wire contracts and a
+  golden cited answer. JDBC shape/transaction tests always run; a pgvector:pg16
+  Testcontainers test skips on hosts without Docker.
+- P-g may invoke the manual service within a designated user's authenticated
+  context. P-f supplies no scheduled runner or stored/elevated session. Multiple
+  replicas should serialize manual re-indexing of a source at the host level;
+  per-record pgvector replacement is transactional, while scan reconciliation is
+  not a snapshot of concurrently changing application data.
+
+### P-g as built
+
+- `assistant_scheduled_task` is admin-only, AI exposure NONE, and appears as
+  Scheduled tasks. The owner-locked, read-only `assistant_scheduled_run` child
+  list retains run status, accounting and a bounded summary. Conversations gain
+  read-only `scheduledTaskId` and `channel` (`panel` or `assistant/scheduled`).
+  Task and run timestamps use the runtime clock; cron uses Quartz and a validated
+  ZoneId, including DST. Enablement and schedule edits recompute `nextRunAt`.
+- Credentials are references, never stored tokens. `credentialEnvName` must
+  match `[A-Z_][A-Z0-9_]*` and the dedicated
+  `allowedScheduledCredentialEnvNames` allowlist. The existing secret resolver
+  supplies its value. Read-only `credentialStatus` reports presence without
+  exposing token characters and is stripped on every save.
+- A run sends JSON `{accessToken: ...}` to the same loopback base URL's
+  `POST /qqq/v1/manageSession`. RC.5 with HTTP-only cookies returns the UUID in
+  `Set-Cookie: sessionUUID`; legacy JSON `uuid` is also accepted. Only then does
+  the runner resolve that UUID through the host authentication module, exactly
+  the UUID lookup used by the UI request pipeline. No direct token authentication,
+  automated-user session or constructed QSession exists in assistant code.
+  The resolved user id must equal `runAsUserId` before any model call. MOCK in
+  the integration fixture maps test tokens to the existing user-prefix sessions;
+  that token adapter is test code only.
+- kof22 provisions an Authentik designated account with normal QQQ permissions
+  and injects an accepted long-lived token through its secret manager and
+  ExternalSecret into an allow-listed environment variable. The task holds the
+  variable name and QQQ user id. Host authentication must accept that token type
+  as `accessToken`; an Authentik management API token is not automatically an
+  application access token. Neither account nor credential is provisioned here.
+- `assistantScheduledTasksRunner` registers a 60-second QScheduleMetaData when
+  `scheduledTasksSchedulerName` names a host scheduler. QQQ supplies its normal
+  scheduler context for assistant-table bookkeeping; no ArchUnit exception is
+  necessary. Configure `uiApiBaseUrl` at startup. No browser visit is required.
+- **Claim compatibility:** RC.5 UpdateInput cannot express a conditional
+  `WHERE next_run_at = expected`. AssistantStore therefore claims the expected
+  schedule slot using the database-enforced unique `(taskId, scheduledFor)` run
+  key and advances `nextRunAt` before login/dispatch. This is a unique-insert
+  optimistic claim rather than a conditional update. The memory fixture also
+  serializes claim operations on its instance. The database constraint, not
+  that monitor, prevents cross-replica duplicate execution. Do not remove claim
+  history or deploy to a backend without atomic unique keys. A crash can lose a
+  run; it never retries a claimed slot. A later tick advances an already-claimed
+  slot left behind by a crash between claim and schedule update.
+- The unchanged AssistantApi starts a new normal turn under the logged-in
+  designated user, preserving start gates, rate limiting, P-c classification,
+  P-d budgets and P-e routing/fallback. An internal context supplies the task's
+  selected profile and additional cost cap. Cost includes chat, classifier,
+  failed calls and knowledge-query embeddings. STOP is checked at dispatch
+  boundaries; an in-flight call can exceed the cap, and no next call is sent.
+- Every scheduled UI API request, including metadata and knowledge retrieval,
+  carries `X-QQQ-Client: assistant/scheduled/<taskId>`. The only uiapi change is
+  additive `LoopbackUiApiGateway.invokeWithClient`; custom gateways currently
+  fail closed for scheduled requests because their channel contract is unknown.
+  Tool-call rows also record `clientChannel`. Core channel deny enforcement
+  remains pending the client-channel RC; existing AI exposure/data-access
+  restrictions continue to apply on RC.5.
+- Approve write mode, Revoke write mode and Run now are admin record actions
+  using standard streamed ETL Review/Result. Review shows the exact prompt's
+  SHA-256 and run-as user. Result rereads and compares the complete reviewed
+  definition before recording the actual administrator's user id and time.
+  A persisted approval hash additionally binds prompt, run-as user, credential
+  reference, profile and requested mode. Editing any of these clears approval;
+  ordinary saves cannot set approval or computed bookkeeping fields.
+- This base has create/update/delete tools, but no W1 conversation mode/policy
+  switch. Scheduled runs explicitly narrow the existing tool policy: write tools
+  require both request and matching approval, a READ_WRITE table and the policy's
+  allowed-tools list. All scheduled writes require panel confirmation, including
+  when normal policy allows immediate writes. A pending proposal adds a waiting
+  notice to the run summary; the scheduler never confirms it.
+- RECORD keeps the run and conversation; NOTIFICATION and BOTH also submit an
+  Alerts notification with `NotificationAudience.user(runAsUserId)` and an
+  `/app/...` conversation link. Reflection targets the installed Alerts QBit's
+  RC.5 notification SPI/sink, following WebhooksAlerts' optional-dependency
+  pattern. Without it, a log contains run id and status only. Notification text
+  contains no answer data. In HIPAA mode run summaries contain exactly
+  `see conversation`; conversation payloads retain the existing encryption.
+    The existing record URL is an admin-screen link. Non-admin owners can read
+    their scheduled conversations in the panel's conversation list; opening a
+    particular existing conversation from a notification still needs a frontend
+    deep-link contract (the current panel only supports open/new-prompt links).
+    This phase does not broaden existing conversation record-screen permissions.
+- Failures close the run as FAILED or BLOCKED with sanitized errors and wait
+  until the next schedule. All output modes retain their audit record. Tests
+  exercise real manageSession and UI API requests with a fixed clock, designated
+  permissions and owner locks, headers, competing runners, approval invalidation,
+  notification modes, PHI refusal, encrypted HIPAA storage and cost STOP.

+/*******************************************************************************
+ ** The assistant's bulk-load tools (design spec #1171 section 3.4): use and
+ ** create saved bulk load profiles from a file the user attached in the chat.
+ ** Every call goes through the /qqq/v1 UI API with the user's own session, so
+ ** table and process permissions, record locks and the PHI rule are enforced
+ ** by the server, never by the model:
+ ** - bulk_profiles_list / bulk_profile_describe: the user's (and shared)
+ **   saved profiles, through the savedBulkLoadProfile table (record locks);
+ ** - bulk_file_attach: an upload the panel already made (by its ref), with
+ **   its column profiles (samples only where the server allows);
+ ** - bulk_mapping_suggest: core's suggester, then the model refines it;
+ ** - bulk_load_dry_run: the table's real bulk-insert validation, no store;
+ ** - bulk_profile_save (write): storeSavedBulkLoadProfile, and shares through
+ **   insertSharedRecord, after the user confirms;
+ ** - bulk_load_run (write): through {@link BulkLoadRunner}, after the user
+ **   confirms (and, as a durable job, again on its job record).
+ **
+ ** The AI route header (X-QQQ-AI-Route: hipaa|standard) is set here from the
+ ** turn's provider, never from the model's input. Tool-call logs keep
+ ** profiles and counts, never sample values (see {@link #forLog}).
+ **
+ ** STAND-IN(core=#1179, removeBy=RC.8): the profile, suggestMapping and
+ ** validate operations ship in a QQQ RC after 4.1.0-RC.5; until then the
+ ** tools report that the server does not offer them.
