Merge remote-tracking branch 'origin/develop' into feature/answer-presentation

Owner priority: answers must be easy to read and act on.

- present_results tool: summary, metrics, table (computed percent
  columns, per-row filtered-list links), bar/pie/line chart from the
  table, filter and record links, follow-up actions. Every table and
  field is checked against what the user can see through the UI API;
  hrefs (/app/<table>?filter=<QQQ filter JSON>, records) and number
  formats are built server-side from metadata; the model never writes
  URLs.
- presentation message part (persisted, SSE event) with a server-built
  multi-line GFM markdown fallback for clients without blocks.
- Static system-prompt Presentation section (built-in default skill):
  answer first, no restating, tables for 3+ items, charts for shares and
  trends, filterLinks whenever a list is offered.
- Golden eval of the owner's example: summary, 2-row table with 80.2% /
  19.8%, a 2-point pie and two mimeType filter links; negative cases.

+## Providers
+
+Add `com.kingsrook.qbits:qbit-assistant-provider-openai` at the same version as
+the QBit and register the adapter alongside any Anthropic adapter:
+
+```java
+config.withProviderType(new OpenAiCompatibleProviderType());
+```
+
+`OpenAiCompatibleProviderType` is in
+`com.kingsrook.qbits.assistant.provider.openai`. Its installed type id is
+`openai-compatible`; provider rows choose OPENAI, AZURE_OPENAI, OPENROUTER,
+OLLAMA, LM_STUDIO, VLLM, LLAMA_CPP or OPENAI_COMPATIBLE as their kind.
+
+- Local kinds use their localhost endpoint by default and need no key. Leave
+  `apiKeyEnvName` empty. An auth proxy can use an explicitly allowed key env name.
+- Cloud defaults use `OPENAI_API_KEY`, `AZURE_OPENAI_API_KEY` or
+  `OPENROUTER_API_KEY`. Values stay in the host's secret store.
+- An override must match an entry in `config.withAllowedBaseUrls(Set.of(...))`.
+  Azure and OPENAI_COMPATIBLE have no default URL and always require an entry.
+  Redirects are not followed. Azure uses the deployment model id and defaults
+  `apiVersion` to `2024-10-21`.
+- **Discover models** adds a provider's Models child list; existing edits survive.
+  Large cloud catalogs (over 20 models) start disabled. **Test connection** is
+  available on both providers and models and records a TEST usage row.
+- A selected registered model must be enabled. With no model selected, the first
+  enabled registry model wins; providers with no model rows retain legacy selection.
+  Registry prices override type/model prices, then configured prices. Unpriced
+  local models cost zero. Capabilities can be adjusted per registered model.
+
+For Ollama behind a TLS proxy with a private CA and bearer authentication:
+
+```java
+config.withProviderType(new OpenAiCompatibleProviderType())
+   .withAllowedBaseUrls(Set.of("https://llm.example.lan:8443/v1"))
+   .withAllowedApiKeyEnvNames(Set.of("LOCAL_LLM_API_KEY"))
+   .withTrustedCaBundleFile("local-llm", Path.of("/etc/app/llm-root-ca.pem"));
+```
+
+Set `LOCAL_LLM_API_KEY` in the server environment from your secret store. In the
+provider record choose kind `OLLAMA`, base URL `https://llm.example.lan:8443/v1`,
+`apiKeyEnvName = LOCAL_LLM_API_KEY`, and `tlsCaBundle = local-llm`. Only the names
+are stored. `withTrustedCaBundle("local-llm", pem)` also accepts one or more PEM
+certificates directly at startup. Invalid PEM fails configuration immediately.
+The named bundle adds to the JVM roots; hostname verification stays enabled.
+Leave `tlsCaBundle` empty to use JVM trust alone. Restart after changing a CA file.
+
+Default tests use localhost mocks. To exercise an existing development server,
+set `ASSISTANT_LIVE_OPENAI_BASE_URL` and `ASSISTANT_LIVE_OPENAI_MODEL`, optionally
+`ASSISTANT_LIVE_OPENAI_KIND` (default OLLAMA), `ASSISTANT_LIVE_OPENAI_KEY_ENV`
+(the variable name containing the key), and `ASSISTANT_LIVE_OPENAI_CA_FILE`
+(a PEM bundle path). Unset or unreachable endpoints, including TLS failures, skip
+the live test. Run:
+
+```sh
+./mvnw verify -pl qbit-assistant-provider-openai -am -Dtest.excludedGroups= -Dgroups=live -Djacoco.skip=true
+```
+
+### AWS Bedrock (Claude)
+
+Add `com.kingsrook.qbits:qbit-assistant-provider-bedrock` at the QBit version and
+register `com.kingsrook.qbits.assistant.provider.bedrock.BedrockProviderType`:
+
+```java
+config.withProviderType(new BedrockProviderType());
+```
+
+Create a provider row with type `bedrock`, kind `BEDROCK`, and the required AWS
+`region` (for example `us-east-1`). Leave `apiKeyEnvName` empty. The server uses
+the AWS default credential chain: environment variables, profiles and container
+credentials (ECS/EKS Pod Identity) work with the transitive dependencies.
+**For IRSA / web-identity credentials, the host application must add
+`software.amazon.awssdk:sts` to its runtime classpath**, matching the transitive
+AWS SDK version. The default chain picks it up when present; this adapter does
+not include STS or the full AWS SDK. Credentials are never stored in tables.
+
+Leave the base URL empty for the SDK's
+`https://bedrock-runtime.<region>.amazonaws.com` endpoint. Overrides, including
+VPC endpoints, must be listed in `withAllowedBaseUrls`. Model ids are Bedrock
+Claude ids or inference profile ids, for example
+`us.anthropic.claude-sonnet-4-5-20250929-v1:0`. The model must be available to the
+server's AWS role in that region.
+
+### Google Vertex AI (Claude, Gemini)
+
+Add `com.kingsrook.qbits:qbit-assistant-provider-vertex` at the QBit version and
+register `com.kingsrook.qbits.assistant.provider.vertex.VertexProviderType`:
+
+```java
+config.withProviderType(new VertexProviderType());
+```
+
+Create a row with type `vertex`, kind `VERTEX`, required `region` (for example
+`us-east5`) and `cloudProject` (the GCP project id). Leave `apiKeyEnvName` empty.
+The server uses Google Application Default Credentials, such as
+`GOOGLE_APPLICATION_CREDENTIALS` or workload identity. Access tokens are refreshed
+when expired, held only in memory, and obtained afresh for each Gemini request.
+
+Models beginning `claude-` (for example `claude-sonnet-4-5@20250929`) use the
+Anthropic Vertex backend's `streamRawPredict` API. All other model ids use Vertex's
+OpenAI-compatible endpoint:
+
+```text
+https://{region}-aiplatform.googleapis.com/v1/projects/{project}/locations/{region}/endpoints/openapi
+```
+
+Unprefixed ids, such as `gemini-2.5-flash`, are sent as `google/gemini-2.5-flash`;
+already-prefixed ids are preserved. Gemini requests omit `strict`, including when
+a tool opts in. An allow-listed base URL overrides the Claude API origin or the
+complete OpenAI-compatible base URL, according to the selected model. Use separate
+provider rows when an override needs different URL prefixes for the two APIs.
+
+Both cloud types default to CLOUD and expose a short static model catalog.
+**Discover models** returns those defaults; it does not call Bedrock's
+`ListFoundationModels` (which needs the control-plane SDK) or Vertex Model Garden.
+Health probes are unsupported; **Test connection** performs the existing one-shot
+completion. Model access and availability depend on the configured region/project.
+`hipaaEligible` is an administrator-recorded fact: a BAA and the associated legal
+and operational requirements remain owner responsibilities. The flag does not
+establish eligibility or implement PHI routing.
+
+The default build tests both clouds using localhost only, fake credentials, AWS
+binary event-stream framing, Claude SSE and Gemini Chat Completions, including
+engine/tool golden turns. No cloud credentials or live endpoints are required.

+
+## Data classification and HIPAA mode
+
+On QQQ 4.1.0-RC.5, classify application tables/fields in the host configuration:
+
+```java
+import com.kingsrook.qbits.assistant.classification.DataClassification;
+
+AssistantQBitConfig config = new AssistantQBitConfig()
+   .withDataClassification("patient", DataClassification.PHI)
+   .withDataClassification("patient", "id", DataClassification.PUBLIC)
+   .withDataClassification("patient", "email", DataClassification.PII)
+   .withDataClassification("patient", "status", DataClassification.PUBLIC)
+   .withHipaaMode(true)
+   .withHipaaRetentionDays(2190)
+   .withConversationEncryptionKeyEnvName("ASSISTANT_CONVERSATION_KEY");
+```
+
+Set that environment variable through your secret manager to a base64-encoded,
+random 256-bit (32-byte) key. Supply only its **name** in config, never the key.
+The existing server-side `withSecretResolver` hook also resolves this reference.
+Startup validates the key. HIPAA mode defaults off; encryption can also be enabled
+with the key reference while HIPAA mode is off.
+
+The qbit `DataClassification` enum is a stand-in for core QRun-IO/qqq#1142, with
+PUBLIC < CONFIDENTIAL < PII < PHI. Unconfigured tables default to PUBLIC; a field
+falls back to its table unless explicitly overridden. A field subset uses its
+selected fields; unrestricted reads and record page contexts use the highest
+classification across the table and its fields. Returned columns and record-label
+fields also count: tools include a primary key even for subsets, so classify it
+explicitly if the host considers it safe for that subset. Cross-table results with unknown
+tables use the highest classification anywhere. Metadata-only tools remain PUBLIC.
+The assistant's own tables remain denied to tools.
+
+Hosts can supply `withClassificationSource(ClassificationSource)` instead. When
+upgrading to an RC containing core #1142, implement that interface with
+`AiDataClassifications`/`AiTableMetaData`/`AiFieldMetaData` (map enum names), then
+replace the stand-in once the qbit's minimum core version includes it.
+
+PHI is sent only to a persisted provider row explicitly marked `hipaaEligible`.
+Every model dispatch rechecks eligibility, including calls after tools and strict
+schema retries. Blocks end the turn with `PHI_BLOCKED` or `HIPAA_PROVIDER`; the
+PHI tool result is never sent to that provider. There is no automatic fallback.
+A conversation keeps its highest classification, so moving to a PUBLIC page does
+not make existing PHI history safe for a non-eligible provider.
+
+HIPAA mode also refuses non-eligible providers at resolution and when enabling
+settings rows, disables code-only fallback, requires encrypted conversation
+storage, and suppresses provider error details in logs and turn errors. The app
+home displays HIPAA mode and PHI retention. The eligibility flag records the
+operator's decision (including any applicable BAA); it does not establish one.
+
+Both modes audit each PII/PHI model call and every routing block in
+`assistant_data_audit` (admin read-only, owner-locked, on the conversation screen).
+PHI conversations use `hipaaRetentionDays` even with HIPAA mode off. A null value
+uses normal retention; tool-result/replay cleanup remains independently configured.
+See [UPGRADE.md](UPGRADE.md) for schema changes, plaintext migration, and key handling.
+
+## Data-driven budgets
+
+Admins configure **Assistant > Budgets** for UTC DAY or MONTH allowances in USD or
+TOKENS, scoped to INSTANCE, USER, ROLE (a permission), PROVIDER or MODEL. Provider
+and model scope values are registry record ids. Warnings default to 80%; at 100%
+the default action is DOWNGRADE, and the hard ceiling defaults to 120% (always
+STOP). Multiple budgets apply together and STOP wins.
+
+An explicit downgrade model is optional. Otherwise the cheapest enabled usable
+model is selected, preferring LOCAL providers. PHI never goes to a provider that
+is not HIPAA-eligible. No eligible target means STOP. Administrators can grant
+extra allowance or temporary unlimited use from the budget's Overrides child list,
+with a required reason and expiry; the session sets the grantor.
+
+Budget state changes appear once per scope/period/state in the Events child list,
+as panel notices and, through core QAlerts, bell alerts when an alerts sink is installed (logging otherwise).
+The Assistant home shows budgets, overrides, daily cost and tokens, and breakdowns
+by user, model, provider and tool. Existing `AssistantBudgets`/policy limits and
+provider monthly caps continue to apply independently of these rows and overrides.
+See [UPGRADE.md](UPGRADE.md) for the required additive schema.
+
+
+### Profile routing and provider fallback
+
+On an Assistant Profile, **Model routing** defaults to OFF. HEURISTIC selects the
+complex slot for long questions (>600 characters), two mentioned app tables,
+analysis/comparison/explanation/trend/planning requests, pending writes, more than
+eight previous turns, or a previous tool limit; otherwise it selects the simple
+slot. CLASSIFIER uses an optional registry model with just the question and a
+fixed instruction, four output tokens and a three-second timeout. An invalid reply,
+error, unavailable classifier or PHI-ineligible classifier uses HEURISTIC. ROUTE
+usage counts toward budgets. Empty model slots keep the provider/policy default;
+budgets may downgrade either choice. Without a profile, enabled code-level
+`AssistantModelRouting.escalation*` supplies the complex default.
+
+A model's **Fallback model** points to its next candidate, including another
+provider. Chains are cycle-free and bounded to four hops. Only retryable failures
+before any text or tool start from that call permit fallback. Disabled, down,
+PHI-ineligible or budget-blocked candidates are skipped. Without explicit links,
+only another LOCAL model in the same adapter family is eligible; local requests
+never automatically move to cloud. Provider state/signatures are removed when
+switching, preserving neutral tool history. Each attempted call is audited as usage.
+
+NETWORK/TIMEOUT marks a provider DOWN for 60 seconds; success marks it UP. Local
+health is probed when unknown/stale with a two-second timeout. Provider cards show
+health and down-until, failures show fallback totals, and turn records show the
+route and final destination. See [UPGRADE.md](UPGRADE.md) for the additive schema.
+
+### Answer presentation
+
+The always-available `present_results` tool turns retrieved results into metrics,
+tables, charts and actionable in-app links. The server validates the user's UI API
+visibility, formats field values, computes shares and builds all links. It emits
+and stores a `presentation` part with a complete GFM Markdown fallback. Profile
+skills can extend the built-in presentation instructions. See the
+[part, stream and input contract](docs/answer-presentation.md).

 # Upgrading qbit-assistant
 
+## P-e: profile routing and provider fallback
+
+Apply the additive **P-e** ALTER TABLE statements at the end of
+[docs/schema-postgres.sql](docs/schema-postgres.sql) before deploying. Existing
+profiles default to OFF; optional model references and health columns start null.
+No routing or fallback configuration is seeded. Existing turns retain unknown
+routing/final-provider values; fallback_count defaults to zero.
+
+Profiles now have a **Model routing** section. Select HEURISTIC or CLASSIFIER,
+then optional simple/complex registry models and a classifier model. Empty route
+slots retain provider/policy selection. CLASSIFIER with no usable classifier
+uses HEURISTIC. OFF preserves prior provider selection. With no effective profile,
+code-configured escalation supplies the complex model/effort when enabled.
+
+Set a model's **Fallback model** to opt into a cross-provider chain. Saves reject
+cycles, more than four edges, or disabled/missing targets. Provider health is
+read-only; NETWORK/TIMEOUT opens a 60-second circuit, and successful calls close
+it. Local endpoints with stale health get a bounded two-second probe. Automatic
+fallback without an explicit link is confined to local models of the same adapter
+family. PHI/HIPAA eligibility and budgets apply to every destination.
+
+Classifier usage is recorded with purpose ROUTE and included in budgets. Reports
+that filter usage purpose should include ROUTE. Turn screens show route decision,
+source, fallback count and final provider; the home shows health and fallback totals.
+All configuration remains assistant.admin-only, with AI exposure NONE.
+
+## P-d: data-driven budgets
+
+Requires QQQ 4.1.0-RC.5 for the core Alerts API and alert type metadata.
+
+Create `assistant_budget`, `assistant_budget_override`, `assistant_budget_event`
+and `assistant_budget_usage`
+using the P-d DDL in [schema-postgres.sql](docs/schema-postgres.sql) before deploying.
+The event unique key is required: it deduplicates each state per budget, scope and
+UTC period across replicas. Do not remove it or truncate events during a period.
+
+Budgets appear in Assistant navigation. Overrides and immutable events are child
+lists. All four tables require `assistant.admin` and have AI exposure NONE.
+Overrides record the actual session grantor and require a reason and expiry.
+The standard host QQQ audit configuration applies to budget and override edits.
+`assistant_budget_usage` is a private accounting projection populated from persisted
+usage writes. It copies only counters, time, user, provider and model, with no owner
+lock, so shared INSTANCE/PROVIDER/MODEL sums can run under the caller's own session.
+The source usage table retains its owner locks. The projection is read-only, has no
+nav entry and no AI exposure. **Pause usage writes during migration and run the DDL's
+backfill before restarting**; otherwise shared totals would omit pre-upgrade usage.
+Keep accounting rows through their budget periods even if detail rows are removed.
+ROLE budgets give each permission holder a separate allowance, checked with their
+current session. Override scopeValue, when set, narrows the allowance to one user id.
+
+Existing policy/config budgets and provider monthly caps remain additional limits;
+an override of a budget row does not waive those existing caps.
+
+Provider and MODEL scope values are numeric provider/model registry row ids;
+USER is a user id and ROLE is a permission name. INSTANCE has no scope value.
+Periods reset at midnight UTC or the first of the month UTC. Token usage includes
+input, output, cache-read and cache-write tokens; USD uses the recorded micro-dollar
+cost, not today's model price. No default budget rows are seeded.
+
+## P-c: classification, PHI routing and encrypted storage
+
+Apply these additive schema changes before deploying P-c (adjust column mappings
+for your backend). New conversations/turns record `PUBLIC`, `CONFIDENTIAL`, `PII`
+or `PHI`; legacy null classifications read as PUBLIC. Backfill known historical
+PHI conversations to PHI before allowing their history to be used with a provider.
+
+```sql
+ALTER TABLE assistant_conversation ADD COLUMN max_classification VARCHAR(16);
+ALTER TABLE assistant_turn ADD COLUMN classification VARCHAR(16);
+ALTER TABLE assistant_turn ADD COLUMN classification_tables VARCHAR(500);
+ALTER TABLE assistant_conversation ALTER COLUMN title TYPE TEXT;
+ALTER TABLE assistant_tool_call ALTER COLUMN result_summary TYPE TEXT;
+ALTER TABLE assistant_pending_action ALTER COLUMN summary TYPE TEXT;

+   id SERIAL PRIMARY KEY,
+   user_id VARCHAR(255),
+   conversation_id INTEGER,
+   turn_id INTEGER,
+   provider_id INTEGER,
+   provider_name VARCHAR(200),
+   model VARCHAR(200),
+   hipaa_eligible BOOLEAN,
+   classification VARCHAR(16),
+   tables VARCHAR(500),

+CREATE INDEX assistant_data_audit_user_id ON assistant_data_audit (user_id);
+CREATE INDEX assistant_data_audit_conversation_id ON assistant_data_audit (conversation_id);
+CREATE INDEX assistant_data_audit_turn_id ON assistant_data_audit (turn_id);
+```
+
+`assistant_data_audit` is an admin read-only, owner-locked child list on a
+conversation, outside navigation. It records each model call carrying PII/PHI and
+each routing block, without record values. It expires with the conversation.
+PHI conversations use `hipaaRetentionDays` (2190 by default), even outside HIPAA
+mode; null uses normal retention. Existing tool-result/replay cleanup still uses
+`toolResultRetentionDays`.
+
+Before enabling HIPAA mode, mark the permitted provider rows `hipaaEligible = true`
+and provision `conversationEncryptionKeyEnvName` with a base64-encoded 32-byte
+key. Startup refuses missing or invalid keys. A code-only provider is not eligible.
+The flag records the operator's eligibility decision; it does not establish a BAA.
+
+New/updated message parts, titles, conversation context, tool payloads/redactions
+and summaries, replay data, and pending-action payloads/summaries use
+`enc:v1:<base64(iv|ciphertext|tag)>` (AES-256-GCM, random 12-byte IV, 16-byte tag).
+Only `AssistantStore` decrypts; direct backend/admin record views show ciphertext.
+String columns holding encrypted summaries/titles must be TEXT to allow expansion.
+Legacy plaintext reads are supported; existing rows are not automatically rewritten.
+For an existing deployment, migrate legacy payloads through AssistantStore under
+the appropriate owner/admin session before treating the whole archive as encrypted.
+Keep the key available for the lifetime of encrypted data and backups. Changing the
+key requires a controlled decrypt/re-encrypt migration; P-c has no key rotation job.
+Corrupt ciphertext, a wrong key, and encrypted data without a key fail closed.

Grant `assistant.admin` holders the new tables through the qbit's existing admin permission (no new permission names).

+Custom CA bundles are server configuration, never database content. Register them
+with `withTrustedCaBundle(name, pem)` or `withTrustedCaBundleFile(name, path)` at
+startup, then set the HTTPS provider row's `tlsCaBundle` to that name. Empty
+references retain JVM default trust. The bundle adds trust without replacing JVM
+roots; hostname verification remains enabled. If the P-a columns were already
+applied, add only `tls_ca_bundle VARCHAR(100)` to `assistant_provider`.

+
+Fresh installations use `docs/schema-postgres.sql`; memory-backed hosts need no
+migration. Existing providers leave the new column null. Vertex requires the GCP
+project id in `cloudProject`; Bedrock and Vertex both require `region` and reject
+`apiKeyEnvName`. They default to CLOUD; `hipaaEligible` remains a manual admin fact.
+
+Add the optional `qbit-assistant-provider-bedrock` and/or
+`qbit-assistant-provider-vertex` module at the QBit version and register
+`BedrockProviderType` / `VertexProviderType`. Credentials come from the server's
+AWS default chain / Google Application Default Credentials. No credentials are
+stored in provider rows. Hosts using AWS IRSA or web identity supply
+`software.amazon.awssdk:sts` on their own runtime classpath (matching the
+transitive AWS SDK version); this QBit does not add it. See README Providers for

@@ -228,6 +228,217 @@ The golden and red-team evals now run through the UI API too.
   - Choosing *another* user would need that user's permissions without their session. QQQ core has no API to evaluate another user's permissions, and the assistant never builds or borrows a session. That part waits for a core API, so the report is always computed with the requester's own session.
 - **Recent denials:** the home's "Recent denials" card lists the newest tool calls the UI API, data access or the policy refused, with who, the table, the operation and the HTTP status, or the assistant setting that refused it.
 
+## Owner decisions (2026-10-13), continued: write mode, the hard wall, audit attribution, providers
+
+These were added on the same day. All recommendations below are accepted; we adjust once they can be seen working.
+
+### W. Write mode: the assistant is just a UI client
+Owner: *"the assistant should be able to go into 'write mode' too - with a user selection or preference? allowing it to do things like create and schedule a report for you, or update a record. it should ALWAYS only have access via the UIUX API (the assistant is just a UI) and all permissions that the user has via the UIUX should always hard apply at a layer above the assistant. All auditing needs to be aware of this too and audit accordingly"*
+
+- **Mode per conversation.** A panel toggle switches between **Read-only** (the default) and **Write**.
+  - The default comes from the user's preference (`assistant_user_preference.default_write_mode`).
+  - An admin policy can disable write mode globally (`assistant_policy.write_mode_allowed`), per role (`write_mode_permission`: only holders may switch to Write), or per table or process (data access READ or NONE).
+- **Read-only:** the write tools are not in the tool list at all. This is decided when the request is built, not by the model.
+- **Write:** every write is still a pending-action card that the user confirms.
+  - A user may set "auto-confirm low-risk writes" only when the policy allows it (`auto_confirm_allowed`).
+  - Low-risk means a single-record insert or update on a table the admin marked `auto_confirm_ok`.
+  - Deletes, bulk operations, processes, report schedules and notifications are never auto-confirmed.
+- **What counts as a write.** All of these are `/qqq/v1` UI API operations:
+  - insert, update and delete records;
+  - run a process (`/processes/{name}/init` and steps; every step is a confirmed action);
+  - create, save or schedule a report or saved view (through the saved-report and scheduled-job tables' own insert operations);
+  - create a notification.
+- **Enforcement is beneath the assistant.** The UI API and core permission layer decide, exactly as for Next UI. The assistant only forwards the user's credentials (`UiApiInvoker`, `UiApiCredentials`, qqq#1128).
+  - The ArchUnit rule (no core actions from the tool code) and the denial matrix stay.
+  - The matrix is extended to every write operation, in both modes.
+
+### X. The hard wall between the assistant and its configuration
+Owner: *"there should also be a hard wall between the assistant and the configuration for the assistant. he should never be able to see his own configuration tables etc."*
+
+AI exposure NONE is not enough, because the assistant acts as the user and an admin user can edit the configuration. The wall is enforced in core, beneath the assistant, by client channel (UI API 1.2.x, approved design):
+
+- Every `/qqq/v1` request the assistant makes carries `X-QQQ-Client: assistant/<turnId>`. It is set server-side by `UiApiInvoker.forServer(server, "assistant")` and `withClientDetail(turnId)`, and the invoker drops any client-supplied value. Core stores it as `QSession.getClientChannel()`.
+- **Deny rules:**
+  - `ClientChannelsMetaData.withDeniedPattern("assistant", "assistant_*")`, plus core's defaults: `authentik_*`, `audit*`, `*api_key*`, `*apiKey*`, `*credential*`, `*secret*` and `webhooks_*secret*`;
+  - `QPermissionRules.withDeniedClients(Set.of("assistant"))` on every assistant process (retention, test connection) and widget.
+  
+  The rules are enforced in `PermissionsHelper`: the object is left out of metadata, and calls get 403, failing closed.
+- The qbit registers **every** `assistant_*` table, process and widget in the deny set. A **startup check** fails the instance if any `assistant_*` object is not denied to the `assistant` channel.
+- Profiles and skills reach the model only as server-assembled instructions. No tool reads or edits them (this is already enforced by ArchUnit), so a prompt injection can never persist itself.
+- The current conversation's context is read by internal code (`AssistantStore`, assistant tables only), never by a tool.
+- **Tests:** an admin through the assistant is denied on every configuration table and process (403, and absent from `list_tables` and `/metaData`), while the same admin through Next UI is allowed.
+
+### Y. Audit attribution
+- Every action records the human user as the actor **and** the client channel: `actor=james@kof22.com via=assistant/<turnId>`, versus `via=next-ui`.
+- Core writes `clientChannel` on `audit` (`AuditsMetaDataProvider.withClientChannelField(true)`, filled by `DMLAuditAction`), so audit screens can filter by channel.
+- `assistant_tool_call` keeps the turn, conversation and model, and links to the audit rows (`auditHref`), so `via=assistant/<turnId>` leads to the conversation, the turn and the model.
+- **Tests:** an assistant write produces audit rows with the human actor and `via=assistant/<turnId>`; the same write from the UI produces `via=next-ui`.
+- kof22 needs a feature-named changeset (`changesets/features/...`) for the audit column.
+
+### P. Providers, local models, HIPAA routing, budgets
+1. **Providers and models as data, any number, each with an enabled toggle.**
+   - Kinds:
+     - Anthropic (exists);
+     - **OpenAI-compatible**, one adapter for OpenAI, Azure OpenAI, OpenRouter, Ollama, LM Studio, vLLM and the llama.cpp server;
+     - **AWS Bedrock** (Claude and others);
+     - **Google Vertex** (Claude and Gemini).
+   - `assistant_provider` gains: kind, base URL, key env reference (unchanged pattern, no stored secrets), local or cloud, `hipaa_eligible` and region.
+   - The new **`assistant_model`** table holds: provider, model id, display name, capabilities (tools, context window, vision, streaming), price in and out per million tokens (0 or a configured compute cost for local models), and an enabled flag.
+   - Test connection works for every provider and every model.
+   - Tool calling follows each provider's rules. The strict-grammar lesson applies: strict only where supported, and a fallback when it is refused.
+2. **Local models** (Mac Studio, and the workstation "lora" with an RTX A5000 24 GB, running Ollama, LM Studio or vLLM; another agent sets up the hosts). Any OpenAI-compatible endpoint is supported, with health checks, model discovery (`GET /v1/models` fills `assistant_model`) and per-provider timeouts.
+3. **HIPAA/PHI routing:**
+   - A data classification on tables and fields in metadata: PHI, PII, CONFIDENTIAL or PUBLIC.
+   - Each turn tracks the highest classification its context and tool results touched.
+   - The policy allows PHI only to `hipaa_eligible` providers (local, or cloud under a BAA). Otherwise it blocks, with a clear reason.
+   - A per-instance **HIPAA mode** (on for MHP, off for kof22) also enforces:
+     - PHI redaction in logs;
+     - encrypted conversation storage;
+     - a separate retention period;
+     - a full audit (who, which classification, which model);
+     - no non-eligible providers.
+   - **BAAs are an owner and legal step**: the flag records a fact; it does not create one.
+4. **Budgets:**
+   - daily and monthly cost and token budgets per user, group or role, provider or model, and instance;
+   - default behaviour: warn at 80% (bell and alert, through the Alerts SPI when present), downgrade to a cheaper or local model at 100%, and stop at a configurable ceiling;
+   - admins can override;
+   - usage and cost over time on the app home, by user, model, provider and tool.
+5. **Extras:**
+   - model routing (simple versus complex, per profile) and fallback chains across providers;
+   - **RAG** over the instance's content: a local embedding model, pgvector, and retrieval filtered by permissions through the UI API as the user;
+   - **scheduled assistant tasks**: recurring prompts that run as a designated user (with that user's stored credentials through the UI API, never a system session) and post results as notifications or records.
+6. Everything goes through the `/qqq/v1` UI API, as the user, with the guarantees above.
+
+### P-a as built
+
+- Per-provider `tlsCaBundle` references startup-parsed, transient server CA bundles. OpenAI-compatible chat, health and discovery trust JVM roots plus the bundle, retain hostname verification, and report sanitized NETWORK errors with a trust hint.
+- `assistant_provider` records kind, location, HIPAA eligibility, region, API
+  version, timeouts and discovery status. `assistant_model` is its admin-only
+  child list: enablement, capabilities, prices and test status, unique per provider/model.
+- `ProviderSettings`, discovery and health extend the provider SPI through default
+  methods. Legacy `create(apiKey, baseUrl)` implementations keep working.
+- The OpenAI-compatible module uses JDK HTTP and Jackson, Chat Completions with
+  SSE or single JSON replies, Azure deployment URLs and api-key auth, and keyless
+  local endpoints. Keys and URL overrides pass the existing allowlists first.
+- Strict tools require explicit opt-in, OpenAI or Azure, and recursively strict
+  object schemas. A strict/schema/grammar 400 signals the existing one-retry fallback.
+- Discovery only adds missing models; it preserves edits and disables catalogs
+  larger than 20 for cloud providers. Health uses a short models request. Provider
+  tests probe health then complete; model tests can probe a disabled model before
+  enabling it. Completion tests record TEST usage.
+- Registry prices and capabilities override adapter/type defaults. Empty provider
+  model selects the first enabled registry model; an explicitly disabled selection
+  is a setup error. Rows without models retain the prior behavior.
+- Localhost contract tests cover dialects, fragmented parallel tool calls, usage,
+  errors, timeouts, cancellation, discovery and a golden tool round trip. The live
+  smoke is environment-driven and excluded by default.
+
+### P-b as built
+
+- Optional Bedrock and Vertex modules reuse the Anthropic mapping and streaming
+  adapter through an injected SDK client. Bedrock retains SDK SigV4 and binary
+  event-stream decoding; a small Backend delegate supplies allow-listed endpoints
+  because SDK 2.71.0 has no Bedrock endpoint setter.
+- Bedrock uses the server's AWS default credential chain; IRSA/web-identity hosts
+  supply STS on their runtime classpath. No STS or control-plane SDK is bundled.
+- Vertex uses scoped Google ADC. `claude-*` routes to the Anthropic backend; other
+  ids route to the OpenAI-compatible endpoint with a per-request token supplier,
+  `google/` for unprefixed ids, and no strict tools.
+- Both types require region, reject key references and default to CLOUD. Vertex
+  additionally requires `cloudProject` (`cloud_project VARCHAR(100)`); it is part
+  of resolved settings and the provider cache key. Type hooks own validation.
+- Discovery is a static catalog, health is unsupported, and Test connection uses
+  the existing completion. HIPAA eligibility remains an admin fact, not a BAA.
+- Localhost contract tests cover wire paths, authentication, text/tools/usage,
+  expired-token refresh, errors, allowlists and golden turns for all three routes.
+
+### P-c as built
+
+- The qbit classification enum is a stand-in for core #1142 until a released RC
+  includes it. Configured table/field overrides are the default; hosts can supply
+  a `ClassificationSource` over core metadata, mapping enum names, then replace
+  the stand-in when the minimum QQQ version advances.
+- Turn/page/tool classification is monotonic, persisted on the turn and retained
+  on the conversation. Field subsets use overrides; unknown cross-table results
+  conservatively use the highest configured level. Metadata tools stay PUBLIC.
+- Small engine hooks check a fresh provider row before every model dispatch,
+  including strict retries. PHI requires explicit row eligibility; HIPAA mode
+  requires it for all calls. Blocks withhold results, explain the rule without
+  values, and write an audit. `ProviderService.eligibleAlternative` is an empty
+  seam for P-e; P-c never changes providers automatically.
+- HIPAA mode refuses non-eligible settings/selection and requires a valid key
+  reference at startup. AssistantStore alone encrypts/decrypts conversation
+  payloads using AES-256-GCM; legacy plaintext reads remain supported and corrupt
+  ciphertext fails closed. No key is persisted. Provider diagnostic text is
+  suppressed in HIPAA logs and turn errors.
+- Admin read-only, owner-locked `assistant_data_audit` records each PII/PHI model
+  dispatch and each block, outside navigation. PHI conversation retention defaults
+  to 2190 days in either mode; shorter tool-result/replay cleanup is unchanged.
+  The app home shows HIPAA mode and PHI retention.
+
+### P-d as built
+
+- ROLE allowances are per permission holder. Shared scopes sum a private immutable
+  accounting projection of usage counters; owner-locked source rows stay locked.
+  Migration backfills existing usage before writes resume. No sessions are elevated.
+
+- Standard admin budget rows add daily/monthly cost or token allowances above the
+  existing config/policy budgets and provider monthly caps. Overrides carry a
+  reason, session grantor and expiry; they never waive the other limit layers.
+- Start-turn checks use the existing 429 BUDGET path through PolicyService.
+  Every dispatch, including strict retries, evaluates current usage and overrides.
+  Events deduplicate WARNED, DOWNGRADED and STOPPED.
+- QQQ RC.5 core QAlerts sends budget signals alongside panel notices, with three
+  admin-visible alert types and a default logging sink. Resolution awaits active
+  alert/recurrence tracking so overrides cannot clear shared alerts incorrectly.
+- Explicit registry model selection leaves provider defaults untouched. Automatic
+  downgrades prefer LOCAL, then price. PHI eligibility and destination provider caps
+  still apply; a missing eligible target stops the turn.
+- The home owns the budget cards and 30-day cost/token bars, with user, model,
+  provider and tool breakdowns, inherited colors and empty states.
+
+### P-e as built
+
+- Profiles select OFF (the migration default), HEURISTIC or CLASSIFIER and optional
+  simple/complex/classifier registry models. Selection uses ProfileService's existing
+  specificity. Without a profile, enabled escalation config supplies the complex
+  model and effort. Empty slots retain provider row/default/policy selection.
+- The documented heuristic is a pure rule table: >600 characters, two distinct app
+  table names, complexity keywords, pending write context, >8 previous turns or a
+  previous tool limit. This branch has no conversation write-mode field.
+- Classifier transport is non-streaming, bounded to four output tokens/three seconds,
+  and contains only the fixed instruction and user question. PHI guards apply before
+  dispatch. Errors/unexpected replies use the heuristic. ROUTE usage enters budget
+  accounting; normal dispatch budgets may override the selected route.
+- FallbackChain follows at most four edges on retryable failures, only before any
+  text/tool start of that call. Candidates are checked for enablement, health,
+  PHI/HIPAA eligibility and budgets. Without explicit links only the same LOCAL
+  adapter family is considered. Provider switches rebuild neutral messages and
+  discard providerState; failed attempts remain visible in usage.
+- ProviderHealth persists UP/DOWN, checked-at and a 60-second connection-failure
+  circuit. Local stale/unknown health uses a bounded two-second probe. Successful
+  completions close the breaker. Turn rows persist route/source, fallback count and
+  final provider/model; notices name only the unavailable and answering providers.
+- Admin record screens, additive Postgres DDL and the flow-layout home expose these
+  settings and counters without granting AI access to assistant configuration.

+## Answer presentation (owner priority 2026-10-13)
+
+`present_results` is always offered and reads no records. It takes a direct answer,
+metrics, a table, an optional table-derived chart, filtered list links, record links
+and next-step actions. The server validates metadata and the user's UI API table
+visibility once per turn, formats values using QQQ field types/display formats,
+computes percentages and builds every `/app` href. Unknown or denied items are
+dropped with an explanation. The assistant must still retrieve every fact through
+data tools before presenting it.
+
+The [presentation part and SSE contract](answer-presentation.md) defines `summary`,
+`blocks` and the complete server-built GFM `markdown` fallback. Each successful
+call emits `presentation` with `{messageId, part}` and persists that part; the tool
+response tells the model not to repeat its tables or links. Audit rows contain
+only accepted presentation data. Normal record-data retention removes these parts.
+
+The built-in Presentation skill is compact static prompt text in the cached rules
+block. It asks for a one-sentence answer first, metrics for single numbers, tables
+for breakdowns/comparisons, charts for useful shares/trends and actual filter links
+whenever offering a list. Administrator profile skills append after it as before
+and extend it; there is no replacement boolean or extra permission surface.
+
+The owner's one-line table was a frontend parsing defect: Next's `AssistantMarkdown`
+used react-markdown without `remark-gfm`, so table lines became a paragraph.
+The renderer fix belongs to `qqq-frontend-next`; this worktree preserves real
+newlines and provides structured blocks plus a proper multi-line GFM fallback.
+The frontend change is maintained separately and is not verified by this build.
+
+The shared golden task asks "How many images do I have by type?": five UI count
+calls establish 81 JPEG, 20 PNG and zero other configured types, then a presentation
+with two rows, 80.2%/19.8% shares, two pie points and working MIME filter links.
+The same task is included in the opt-in `live` Anthropic eval suite.

+# Assistant answer presentation contract (v1)
+
+Owner priority (2026-10-13): answers must ALWAYS be easy to read and act on. Bad example the owner saw, rendered on ONE line:
+"| Type | Count | |---|---| | JPEG (image/jpeg) | 81 | | PNG (image/png) | 20 | | WebP, GIF, SVG | 0 |" followed by "You can open the lists filtered by JPEG or PNG" with NO links.
+
+Root cause found in Next: `AssistantMarkdown` uses react-markdown WITHOUT `remark-gfm`, so GFM tables are not parsed and the table's lines collapse into one paragraph (soft line breaks). Backend streaming preserves `\n` (events are JSON).
+
+## New message part: `presentation`
+
+An assistant message's `parts` (persisted in `assistant_message.parts_json`, streamed as an SSE event, returned by the conversation API) may contain, besides `text`, `notice`, `tool`/`render` parts etc., ONE part per `present_results` call:
+
+```json
+{
+  "type": "presentation",
+  "summary": "101 media files are images: 81 JPEG and 20 PNG.",
+  "markdown": "<server-built GFM fallback of the whole presentation, for clients that do not render blocks (CLI/TUI)>",
+  "blocks": [
+    { "kind": "metrics", "items": [ { "label": "Images", "value": 101, "display": "101", "href": "/app/media?filter=..." } ] },
+    { "kind": "table", "title": "Media by type",
+      "columns": [ { "key": "type", "label": "Type", "align": "left" },
+                   { "key": "count", "label": "Count", "align": "right" },

+      "rows": [ { "cells": { "type": "JPEG (image/jpeg)", "count": 81, "share": 0.802 },
+                  "display": { "type": "JPEG (image/jpeg)", "count": "81", "share": "80.2%" },
+                  "href": "/app/media?filter=..." } ] },
+    { "kind": "chart", "chartType": "pie", "title": "Share by type",
+      "points": [ { "label": "JPEG", "value": 81, "display": "81", "href": "/app/media?filter=..." },
+                  { "label": "PNG", "value": 20, "display": "20", "href": "/app/media?filter=..." } ] },
+    { "kind": "filterLinks", "items": [ { "label": "Open JPEG media (81)", "tableName": "media", "href": "/app/media?filter=..." } ] },

+  ]
+}
+```
+
+Rules:
+- `summary` is required, one sentence, the direct answer first.
+- `chartType` ∈ `bar`, `pie`, `line`; ≤ 12 points; values are numbers.
+- Every `href` is built SERVER-SIDE from metadata and is an `/app` path (same rules as `TurnEngine.isAppHref`). Filtered list links are `/app/<tableName>?filter=<URL-encoded JSON {"criteria":[{"fieldName":..,"operator":..,"values":[..]}],"booleanOperator":"AND"}>`, which Next's `deserializeFilter` accepts (JSON starting with `{`). The model never writes URLs.
+- `display` strings are formatted server-side from field metadata (`displayFormat`, e.g. `%,d`, `$%,.2f`; percent columns as `80.2%`); clients show `display` when present, else the raw value.
+- `actions` items have either `prompt` (send as the user's next message) or `href` (navigate), never both.
+- Unknown `kind`s must be ignored by clients (forward compatible); clients that do not render blocks render `markdown`.
+- The SSE event is `presentation` with `{ "messageId": <id>, "part": <the part above> }`; Next's reducer appends it to the assistant message's parts.
+
+## Tool input and implementation
+
+The input schema is [present-results.schema.json](../qbit-assistant/src/main/resources/present-results.schema.json). `table.rowKeys` supplies one raw filter value per row; `table.rowFilter` names the table, field and optional operator (EQUALS by default). Columns receive stable server keys `c0`, `c1`, etc. Input cells remain raw scalars; each row has a parallel display map. The example keys above are illustrative.
+
+`PresentResultsTool` is instantiated per turn. It caches `GET /metaData` with that turn's session, checks table read visibility and instance fields, validates QQQ criteria operators and builds paths using RC.5 `AiLinkBuilder`. Filter links use URL-encoded JSON accepted by Next. Record ids are encoded as opaque path segments. Metadata denial or invalid item drops that item (an invalid table drops its table/chart), with a short explanation to the model; other items survive. No data query or permission elevation happens here.
+
+Limits: summary 300 characters, display text 2,000 characters, table 20 columns/200 rows, chart 12 points, item lists 100 entries, filters 20 criteria/200 values. Chart truncation is reported to the model. Percent columns reference a raw numeric column; a zero total yields 0.0%. Numbers still must originate in earlier data tool results; presentation is formatting, not a new source of facts.
+
+The schema uses small named, nonrecursive definitions to avoid deeply inlined structures. Each object component is at most two levels of inline containers; the resolved table/criteria structure necessarily has the nesting shown in the owner contract. Strict is off by default. Opting `present_results` into strict mode requires all properties (empty arrays/strings, empty table and -1 for unused percentage indexes), removes provider-unsupported length constraints, and retains server validation. This has zero optional parameters and one shared scalar union in the existing strict-budget test.
+
+Presentation parts are persisted with the assistant message and replayed as `presentation` events with `{messageId, part}` (plus the standard event sequence). They are removed by record-data retention along with tool renders. Model history and text-only consumers can use the server-built Markdown. Unknown block kinds should be ignored. Plain labels must be rendered as text, never parsed as links or HTML; fallback Markdown escapes them. Tool audit input records the accepted presentation only, excluding dropped values.

+# OpenAI-compatible provider registry demo
+
+Run from the repository root in PowerShell with Java 21. This is a manual,
+memory-backed screenshot server, not a Surefire test. Nothing is persisted
+between runs. No API keys or external model services are needed: the secret
+resolver deliberately returns no keys, including when the shell has credentials.
+
+Build the test classpath (the local reactor class directories come first below,
+so the demo uses this checkout's code and fixture):
+
+```powershell
+.\mvnw.cmd -q -pl qbit-assistant-provider-openai -am test-compile dependency:build-classpath '-Dmdep.includeScope=test' '-Dmdep.outputFile=target/demo-classpath.txt'
+if ($LASTEXITCODE -ne 0) { throw 'Demo compilation/classpath generation failed' }
+
+$demoDependencies = (Get-Content qbit-assistant-provider-openai/target/demo-classpath.txt -Raw).Trim()
+$demoFrontend = "$env:USERPROFILE/.m2/repository/com/kingsrook/qqq/qqq-frontend-next/1.0.0-RC.18/qqq-frontend-next-1.0.0-RC.18.jar"
+$demoClasspath = "qbit-assistant-provider-openai/target/test-classes;qbit-assistant-provider-openai/target/classes;qbit-assistant/target/test-classes;qbit-assistant/target/classes;$demoFrontend;$demoDependencies"
+java -cp $demoClasspath com.kingsrook.qbits.assistant.provider.openai.demo.OpenAiDemoServer 8099
+```
+
+The frontend artifact is `com.kingsrook.qqq:qqq-frontend-next:1.0.0-RC.18`,
+already in the local Maven repository. Adjust `$demoFrontend` if your Maven
+local repository is elsewhere. Omit the final port argument for the default
+8099, or use another free port (the smoke check used 18099). Stop with Ctrl+C.
+
+Startup prints these URLs (with the selected port):
+
+- Assistant home: `http://localhost:8099/app/assistantAdmin`
+- Local provider: `http://localhost:8099/app/assistant_provider/1`
+- Priced and tested model: `http://localhost:8099/app/assistant_model/1`
+
+Every browser session is `admin-demo`. Startup inserts an enabled, default,
+keyless Local GPU (Ollama) provider, marked LOCAL and HIPAA eligible for the
+synthetic demo, and a disabled CLOUD OpenRouter provider whose key is Not set.
+If the Anthropic module is explicitly added to the classpath, its provider type
+and a disabled Claude (production) row are also included; otherwise it is skipped.
+
+The normal Discover models process fetches four model IDs from the localhost
+mock: `qwen3:30b-a3b`, `gpt-oss:20b`, `qwen3-coder:30b`, and `bge-m3`.
+A normal update sets qwen3's input/output compute prices to $0.05/$0.10 per
+million tokens. The provider and model Test connection processes then each
+make a real HTTP completion call, recording two TEST usage rows and the
+last-test fields. One assistant turn records a third usage row with purpose
+TURN. Discovery timestamps/status also come from the actual process.
+
+Replies and token counts are synthetic mock API responses (24 input / 8 output
+tokens per completion), not live GPU measurements or billed cloud usage.
+No usage/history rows are manually seeded. The mock remains available for
+repeating discovery, connection tests and chat while taking screenshots.
+
+Capture the P-a screens in light and dark at 390 and 1440 px; see
+[`docs/screenshots/README.md`](../../../../../../../../../../../docs/screenshots/README.md)
+for the planned screenshot prefixes.

+# Test-only TLS fixtures
+
+These certificates and the private key in `server.p12` are synthetic test material.
+They must never be used for deployment or trusted outside tests. The PKCS12
+password is `test-only`. The CA private key is not retained in the repository.
+BouncyCastle was not on the test classpath, so fixtures were generated with the
+JDK 21 **keytool executable**, not internal `sun.security` APIs.
+
+The leaf is signed by `QBit TEST ONLY Root CA` and has only `DNS:localhost` in its
+SAN; connecting to `127.0.0.1` deliberately fails hostname verification. Both
+certificates start on 2020-01-01 and last 36,500 days to avoid date-dependent tests.
+Each regeneration creates fresh random keys. Run in a temporary directory, then
+copy only `ca.pem` and `server.p12` here:
+
+```sh
+keytool -genkeypair -alias ca -keyalg RSA -keysize 2048 -dname 'CN=QBit TEST ONLY Root CA' -ext bc:c=ca:true -ext ku:c=keyCertSign,cRLSign -startdate '2020/01/01 00:00:00' -validity 36500 -keystore ca.p12 -storepass test-only -storetype PKCS12 -noprompt
