Merge pull request 'feat(access): writes follow the signed-in person; no answer without a spending limit; a fourth review of the tool boundary closed' (#109) from feat/writes-follow-the-person into develop

Package A2 of the actions design (docs/actions-and-mcp.md, sections 2 and 3),
with two owner decisions of 2026-11-12, and five findings of an independent
review of the tool boundary, each closed by the guarantee it gives.

Writes follow the person
- The data access of a table or process is declared in versioned code:
  AssistantQBitConfig.withDefaultTableAccess / withDefaultProcessAccess (both
  READ_WRITE) and a pin per object (withTableAccess, withProcessAccess).
  READ_WRITE grants nothing: the assistant may propose what the signed-in
  person may do themselves, and every change waits for their confirmation.
- An administrator's assistant_data_access row can only narrow (READ, NONE).
  It never raises a code default, a pin or a table kept from AI.
- Every assistant_* table and every process of the QBit is NONE by a pin in
  code that no row and no host pin lifts.
- The write tools are offered to a person who may create, edit or delete
  records of some table (asked of the UI API as that person, once per offer,
  within the tool-call time limit; no answer means no write tool). GET /config
  features.writes is that answer for the person.
- Settings that cannot be read, and were never read, allow nothing.
- The table action "Add rows for every table" is retired. The changeset
  assistant-data-access-follow-user removes the unedited READ rows it wrote,
  and no other row.

No answer without a spending limit
- A person for whom no spending limit is in force (BudgetService.limitInForce)
  is refused: the turn before anything is stored, every model call, every tool
  call, every embedding request, a scheduled turn. Restoring a limit restores
  service on the next request.

Review findings
- A pending action is never marked expired over its outcome: expiry is a
  decision made through the same claim as confirming and cancelling.
- No action stays RUNNING for ever: retention ends one left running for more
  than an hour as FAILED ("outcome unknown, check the record"), with a log row.
- A person is the session the authentication module resolved, not the object
  passed in: a hand-made permission gives nothing, a revoked one is gone.
- The assistant's own reads get their context from the tool-call service, for
  a person it checked; there is no public way to make a tool context from a
  session id, a gateway and a policy.
- The published test-jar holds the testing package only.
- AssistantStore's decision methods are final.

 # Changelog
 
+## Unreleased - Writes follow the signed-in person; no answer without a spending limit; a fourth review closed
+
+Builds package A2 of the actions design (`docs/actions-and-mcp.md`, sections 2 and 3): the assistant may propose any change the signed-in person may make themselves, by default, with the defaults declared in versioned code. It also closes five findings of an independent review of the tool boundary, each described by the guarantee it gives. **Two behaviour changes need an administrator's attention before deploying: see UPGRADE.md.**
+
+- **Writes follow the person, with no settings row** (owner decision, 2026-11-12). The data access of a table or a process is declared in code: `AssistantQBitConfig.withDefaultTableAccess` and `withDefaultProcessAccess` (both `READ_WRITE` by default) and a pin per object, `withTableAccess(table, mode)` and `withProcessAccess(process, mode)`. `READ_WRITE` grants nothing: it lets the assistant propose what the person may do themselves, and every change still waits for that person's confirmation card. Before, a table was `READ` until an administrator stored a `READ_WRITE` row.
+- **An administrator's `assistant_data_access` row can only narrow.** `READ` makes a table read-only for the assistant, `NONE` hides it. A row never raises what the code says: not a code default of `READ`, not a pin, not a table whose metadata keeps it from AI. `DataAccessService.Decision.source` says what decided ("default", "pinned in code", "administrator setting", "sensitive table"), and the Data access card and every refusal show it.
+- **The assistant's own tables and processes are `NONE` by a pin in code that nothing lifts**: every `assistant_*` table (policy, providers, models, prices, budgets and overrides, data access, profiles, skills, knowledge sources, scheduled tasks, conversations, tool calls, pending actions, usage) and every process of the QBit, whoever asks, with a `READ_WRITE` row and a host pin on it. This is in addition to core's channel wall.
+- **The write tools are offered to a person who may change something.** `create_record`, `update_record` and `delete_record` (and the bulk-load save and run tools) are offered when the UI API says the person may create, edit or delete records of some table whose data access allows writes; `save_analysis` when they may save an analysis. The question is asked as the person, once per offer, within `toolCallTimeoutSeconds`; no answer means no write tool. `GET /config` `features.writes` is now that same answer for the person (it was "some table has a READ_WRITE row"). The person's permission for a particular change is still decided by the UI API when the confirmed change runs, with the screen's own status and message.
+- **Settings that cannot be read allow nothing.** When the administrator's rows cannot be read and none were ever read, every table is `NONE` until they can be (the fallback used to be the old default). Rows read earlier stay in force.
+- **"Add rows for every table" is retired** (`assistantDataAccessAddDefaults`, `DataAccessDefaultsProcess`), with its help. It wrote the old default out as rows, which would now read as restrictions. The shipped changeset `db/liquibase/qbit-assistant/assistant-data-access-follow-user.changelog.sql` removes the `READ` rows it wrote that nobody changed, and no other row. The Data access card on the Overview shows the effective mode and its source for every table without storing anything.
+- **No answer without a spending limit** (owner decision, 2026-11-12). The assistant refuses a person for whom no spending limit is in force: a turn is refused before anything is stored and before any model call (HTTP 429, code `BUDGET`, "The assistant is not answering because no spending limit is in force. An administrator must set or switch on a budget (Assistant > Budgets) before it can be used."); so are every later model call of a running answer, every tool call, every embedding request and a scheduled turn (whose run records the sentence). A limit is in force when a hard limit above zero is declared in the code configuration or on the policy row, or a budget row is switched on, has a limit above zero and applies to the person (`BudgetService.limitInForce`). A row that is switched off, a zero limit, a row for somebody else and a soft limit alone do not count. Restoring a limit restores service on the next request. A row whose limit is not above zero is no longer evaluated at all (it used to fail the evaluation).
+- **A pending action is never marked expired over its outcome** (review 1). Expiry is now one of the decisions an action can have: it goes through `AssistantStore.decidePendingAction` (a claim with the decision `EXPIRED`), like confirming and cancelling, so only an action that is still pending and unclaimed is expired. `ToolCallService.expiredIfDue` decides from the stored action and the runtime's clock, never from a copy read earlier. `AssistantStore.expirePendingAction(id)` is replaced by `expirePendingAction(userId, id, now)`, which answers whether it expired the action.
+- **No action stays RUNNING for ever** (review 2). The retention process first ends confirmed changes that were left `RUNNING` for more than an hour (the server stopped while one ran) as `FAILED`, with "Outcome unknown: this change was started and its end was never recorded. Check the record before asking for it again." and a tool-call log row; they are then removed, with what they kept of the record, like any other decided action once older than `approvalRetentionDays`. `AssistantRetentionStep.purge(runtime, now)` does both steps; the process reports `pendingActionsFailed`.
+- **A person is the session the authentication module resolved** (review 3). `SignedInPerson.ofSession(qInstance, session)` used to check the session's id and then keep the object it was given. It now makes the person from the session the module resolved: a permission added to a session by hand gives the person nothing, and a session kept from earlier does not keep a permission that has since been taken away. Only the time zone is carried over.
+- **The assistant's own reads go through the service** (review 4). `UiApiToolbox.Context.forRead(sessionUUID, timezone, gateway, policy, credentials, turnId)` is gone: there is no public way to make a tool context from a session id, a gateway and a policy. `ToolCallService.readContext(person, timeout)` makes the context of a read the assistant makes for itself (the starter prompts, the knowledge index), after checking the person, assistant access and the kill switch, with the policy it reads itself and the runtime's gateway. `Context.forRead(timeout)` and `forReadWhateverTheToolSwitches()` only derive a narrower context from one the service made. These reads have no tool-call log row, by decision: nothing of a starter-prompt read reaches a model, a knowledge hit is read again inside a `search_knowledge` call that has its row, and an index run reads every record of its source as the administrator who started it and has its process record. The UI API's access log names the assistant as the client for all of them.
+- **The published test-jar holds the fixture and the harness, nothing else** (review 5). It is built from `com/kingsrook/qbits/assistant/testing/**` only. The helpers this module's own tests use to reach behind the tool-call service (`RuntimeInternals`, `ToolCallServiceInternals`, `Toolboxes`) and the tests themselves are no longer published. The provider modules use `AssistantTestFixture`, `TurnRunner`, `GoldenTasks`, `PresentationGoldenTask`, `EvalSupport` and `CloudProviderTestServer`, all in that package, and are unchanged.
+- **The decision cannot be replaced by a subclass.** `AssistantStore.decidePendingAction`, `expirePendingAction` and `failAbandonedPendingAction` are final. The store itself stays open to subclassing, which this repository's tests use to make a read or a write fail.
+- New on `ToolCallService`: `offersAny(person, toolNames)`, `readContext`, `expiredIfDue`, `failAbandonedActions`. `ToolOffer` carries the credential of the person's request. `StarterPrompts.forUser(person, policy, ...)` is gone (the caller asks the service for the context); `BulkLoadToolFamily` no longer takes the data toolbox; `UiApiToolbox.definitions(policy, boolean)` is `definitions(policy, Set<String> writableTables)` and `UiApiToolbox.anyWritableTable()` is gone.
+- UI API extension `assistant`: no new operation and no changed field; the description of `features.writes` says what it now means.
+- Not in this change: any new tool (process, report and schedule tools are the next packages); the panel. The write tools' descriptions still end "unless the administrator turned confirmation off", which no longer can happen: they are part of the cached request prefix and are left for a change that touches it on purpose.
+- Tests: `DataAccessPrecedenceTest` (the precedence as a table, for tables and processes; the pin on the assistant's own objects; sensitive tables; unreadable settings), `WritesFollowThePersonTest` (the tool lists for a person who may and may not change a table, with no settings row; narrowing to read-only and to not at all; a row cannot widen past the person, a pin or the assistant's own tables; the screen's own refusal), `DataAccessFollowUserChangelogTest` (the changeset twice on a fresh schema, on written-out and hand-written rows, and without the table), `NoSpendingLimitTest` (each way a limit is not in force; restored on the next request; a limit removed during an answer), `PendingActionExpiryTest` (a list that read the action before it was confirmed; a confirmation and an expiry at once, twenty rounds; an action left running), `SignedInPersonTest` (a hand-made permission, a revoked permission), `AssistantOwnReadsTest`, `TestJarContentsTest`, and new rules in `ToolCallArchitectureTest`. `ToolCallChecksTest` passes unchanged. `ChatToolSetTest` passes with the definitions unchanged; see UPGRADE.md for the one line of its expected list that changed and why.
+- Test only: the random canaries of `TranscriptRedactionTest` and `ScheduledTasksTest` have no digits any more. The scan for a leaked canary looks for every five characters of it, and five digits in a row also turn up by chance in a stored timestamp's fraction of a second, which failed a build that leaked nothing.

 Closes what a third independent review of the tool boundary found, and builds the pending-action package of the actions design on top (before and after values, kinds, a list, retention). Each fix is described by the guarantee it gives.

   - A tool is looked up only in the registry. Outside `tools/`, only `engine/ToolCallService` runs a tool or writes an `assistant_tool_call` row (ArchUnit); the turn engine and the confirm route both go through it. A tool call runs as the signed-in person, with their current permissions and budget, never as the assistant; a refusal happens before any data action; every call that ran has a log row with redacted input.
   - `ToolCallService` trusts no caller and takes nothing it can find out itself. A caller hands it a `tools.registry.ToolCall` (a `SignedInPerson`, the call's id, name and input) and nothing else: the service reads the policy fresh on every call (`PolicyService.current(true)`, narrowed for a scheduled task's conversation; never the cache), builds the tool `Context` with the gateway the runtime handed it and keeps the proposed writes itself.
   - The boundary holds at compile time for code outside the assistant's packages, not only by ArchUnit. Keep it so: `ToolCallRequest`, `ConfirmedToolCall` and `UiApiToolbox.Context` are final classes with no public constructor, made only through `of(ToolCallService.Permit, ...)`; the permit has a private constructor and the service never hands its own out. `AssistantRuntime` has no public getter for the tool registry, the UI API gateway, a toolbox or its tool families: it hands them to the collaborators it builds. Never add a public way to any of them, and never a public method on the service that runs a tool without writing its row.
-  - Its public entry points: `executeAndLog(call, conversationId, hipaaRoute)` for a caller with no turn (the service makes the scope); `confirm(person, pendingActionId)` and `cancel(person, pendingActionId)`, called only by `AssistantApi` (ArchUnit); `offers(person, toolName)`. `execute(call, scope)`, `log(call, scope, outcome)` and `withdraw(call, scope)` are package-private, for the turn engine only.
-  - On every call, before the tool is reached, it checks: a signed-in person, assistant access, the kill switch, that the scope's conversation and turn are that person's, the policy (unreadable refuses), the hard budget (read on every call, never remembered per scope; one aggregate query per budget through `AssistantStore.sumUsage`, never the usage rows) and that the tool is offered to this person now. What a caller still supplies (rate limiting, per-request call limits and timeouts, classification, the HIPAA route) is listed in the service's javadoc.
-  - `SignedInPerson` binds a session to the one credential forwarded to the UI API. It has no public constructor: `ofRequest(Context)` (only `AssistantSpecs`, ArchUnit; it forwards only the credential the session was resolved from) or `ofSession(qInstance, session)` (the session's own id is the credential: the authentication module resolves it, and it must be the user the session names). Never make a person from a session that was not checked, never pass a session and credentials separately, and never let the turn engine make a person.
+  - Its public entry points: `executeAndLog(call, conversationId, hipaaRoute)` for a caller with no turn (the service makes the scope); `confirm(person, pendingActionId)` and `cancel(person, pendingActionId)`, called only by `AssistantApi` (ArchUnit); `offers(person, toolName)` and `offersAny(person, toolNames)`; `readContext(person, timeout)` (only `AssistantApi` and `RagService`, ArchUnit); `expiredIfDue(userId, action)`; `failAbandonedActions(now)` for the retention process. `execute(call, scope)`, `log(call, scope, outcome)` and `withdraw(call, scope)` are package-private, for the turn engine only.
+  - On every call, before the tool is reached, it checks: a signed-in person, assistant access, the kill switch, that the scope's conversation and turn are that person's, the policy (unreadable refuses), the hard budget (that a spending limit is in force at all, then the limits; read on every call, never remembered per scope; one aggregate query per budget through `AssistantStore.sumUsage`, never the usage rows) and that the tool is offered to this person now.

Never make a person from a session that was not checked, never read access, the owner key or a permission from a session object a caller handed over, never pass a session and credentials separately, and never let the turn engine make a person.
   - The toolboxes cannot be called around the service: their entry points that run a tool are package-private, the runtime has no getter for a toolbox (each family is handed its own), and no class outside `tools/` calls into it except through the registry (ArchUnit, with a short allow-list: the runtime's wiring, the value types, and `UiApiToolbox.read`, the four read-only tools the starter prompts and the knowledge index use).
+  - `UiApiToolbox.read` needs a `Context`, and every context is made by the service: `ToolCallService.readContext(person, timeout)` for a read outside a tool call (it checks the person, assistant access and the kill switch, reads the policy itself and uses the runtime's gateway), or the context of the tool call the read is part of. `Context.forRead(timeout)` and `forReadWhateverTheToolSwitches()` only derive a narrower one. Never add a public way to make a context from a session id, a gateway or a policy. These own reads have no tool-call log row (nothing of them reaches a model; an index run has its process record) and do not ask the hard budget (they call no model).
   - The turn engine writes one row per started call in a per-call `finally`: a call that ran past its time limit, one whose result could not be processed, and a batch the engine was interrupted in all keep their rows, of the real outcome when the worker finished. A row that cannot be written for a call that changed data is logged at ERROR.
   - A missing policy refuses; it never means "every tool".
   - 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`.

+  - Data access (`DataAccessService`) and the policy only ever narrow what the UI API allows. The mode of a table or process is declared in versioned code: the default (`withDefaultTableAccess` / `withDefaultProcessAccess`, READ_WRITE) or a pin (`withTableAccess` / `withProcessAccess`). An administrator's `assistant_data_access` row narrows it and never raises it. A table whose AI exposure is NONE stays NONE, and so does every `assistant_*` table and every process of the QBit (`DataAccessService.isOwnTable`: a pin in code that no row and no host pin lifts). Rows that cannot be read and were never read mean NONE for everything, never the default.
+  - READ_WRITE grants nothing: the write tools are offered to a person only when the UI API says that person may create, edit or delete records of some table (`UiApiToolFamily.writableTables`, asked as the person, once per offer, within `toolCallTimeoutSeconds`; no answer means no write tool). The person's permission for the change itself is decided by the UI API when the confirmed change runs, with its own message. Never materialise defaults as rows again: the retired "Add rows for every table" action is why `assistant-data-access-follow-user.changelog.sql` exists.
   - A write runs only after the owner confirms its pending action, with the confirming request's session, once; no policy or caller can turn confirmation off (`assistant_policy.writesRequireConfirmation` is no longer read). `ToolCallService.confirm` loads the stored action for that person, claims it, runs it and writes its row; whatever fails after the claim ends in FAILED with a row, never in RUNNING.
-  - A pending action is decided once: confirming and cancelling both go through `AssistantStore.decidePendingAction`, which inserts the action's row into `assistant_pending_action_claim` (unique `pendingActionId`). Never decide an action with a status update alone, and never drop that unique key.
+  - A pending action is decided once: confirming, cancelling and expiring all go through `AssistantStore.decidePendingAction` (final; `expirePendingAction` is a claim with the decision EXPIRED), which inserts the action's row into `assistant_pending_action_claim` (unique `pendingActionId`). Never decide an action with a status update alone, never expire one from a copy read earlier or a time a caller names (`ToolCallService.expiredIfDue` decides from the stored action and the runtime's clock), and never drop that unique key.
   - What was approved is what is written: `update_record` and `delete_record` read the record as the person when they propose and keep its version (a digest of the whole record, never values; `beforeJson` holds only what the card showed, after the exposure rules of get_record). A confirmed update or delete reads the record again and refuses when it changed, is gone or cannot be read. A proposal without a version is refused, not run.
   - A tool call whose own outcome the turn engine did not take (timed out, stopped, failed, unprocessable) shows no card, so the engine has the service withdraw what it proposed; a proposal made after that is refused.
-  - Retention deletes decided and lapsed pending actions older than `approvalRetentionDays`, with or without a conversation; one left RUNNING is kept.
+  - Retention first ends pending actions left RUNNING for more than `ToolCallService.ABANDONED_AFTER` (one hour) as FAILED, with "outcome unknown, check the record" and a tool-call log row, then deletes decided and lapsed pending actions older than `approvalRetentionDays`, with or without a conversation. No action stays RUNNING for ever.

The service's constructor is public (the runtime is in another package), so other code can construct a service of its own, with a registry, a store and a gateway of its own choosing. Such a service checks what those let it check; it does not run the runtime's checks, and it is not a way around them: it cannot be given the runtime's registry, gateway or toolboxes, and whatever it calls is still the UI API as a signed-in person, with that person's permissions. The single decision of a pending action cannot be replaced by a subclass of the store (`AssistantStore.decidePendingAction` is final).

 # Upgrading qbit-assistant
 
+## Writes follow the signed-in person; the assistant needs a spending limit (Unreleased)
+
+**After this upgrade the assistant proposes changes on every table the signed-in person may change themselves, with no settings row, and it refuses to answer anybody for whom no spending limit is in force.** Both are owner decisions of 2026-11-12. Every change still waits for the person's confirmation card, runs as that person through the UI API, and is refused there, with the screen's own message, when they may not make it. No DDL changes.
+
+### What a host must apply
+
+1. **Include the migration changeset** in the master changelog, once, after the assistant's tables:
+
+   ```yaml
+   - include: { file: db/liquibase/qbit-assistant/assistant-data-access-follow-user.changelog.sql }
+   ```
+
+   It deletes the rows of `assistant_data_access` that the retired table action "Add rows for every table" wrote and nobody changed since: type `TABLE`, mode `READ`, the action's fixed note, and a modify date less than one second after the create date. It touches no other row: not a row an administrator wrote or changed, not a `NONE` or `READ_WRITE` row, not a `PROCESS` row. Its rollback is empty. A host that never ran that action has nothing to remove and may still include it. A host with its own migration tool runs the one `DELETE` of that file.
+
+   Without the changeset nothing breaks: each of those rows now reads as a restriction, and the assistant stays read-only on that table until the row is deleted.
+
+2. **Review the rows that remain** on Assistant > Data Access in every environment, before deploying. A row no longer opens anything. What each row means now:
+
+   | Row | Before | After |
+   |---|---|---|
+   | none | the assistant may read the table | the assistant may read it and propose what the person may change |
+   | `READ` | the same as no row | **a restriction**: the assistant never proposes a change to this table |
+   | `NONE` | the assistant never sees the table | unchanged |
+   | `READ_WRITE` | the assistant may propose changes to this table | no restriction, the same as no row: delete it or keep it |
+
+   Which rows exist in a deployed database cannot be read from code; an administrator has to look.
+
+3. **Make sure a spending limit is in force**, or the assistant refuses every question after the upgrade. One is, when a budget row on Assistant > Budgets is switched on, has a limit above zero and applies to the person (a whole-instance budget applies to everybody), or when the code configuration or the policy row declares a hard limit above zero (`AssistantBudgets` user daily or instance monthly). The starter defaults changelog seeds a monthly whole-instance budget on a host that had no budget; a host that deleted or switched off its budgets, or never included the starter defaults and declares no hard limit, must add one. The Setup card's Budgets line says so.
+
+### What changes for administrators
+
+- **Data Access rows only restrict.** Add a row to make a table read-only for the assistant (`READ`) or to hide it (`NONE`). There is no longer a way to open a table from that screen, because nothing needs opening: the assistant follows each person's own permissions. The mode's help text and the Data access card on the Overview say what decided for each table ("default", "pinned in code", "administrator setting", "sensitive table").
+- **The table action "Add rows for every table" is gone.** The Data access card shows the effective access of every table, and its source, without storing anything.
+- **People who may change a table are offered the write tools at once**, on every table they may change. A person who may only read is not offered them. Tell the people who use the assistant: the card is the moment to check.
+- **With no budget in force the assistant says so and stops**: "The assistant is not answering because no spending limit is in force. An administrator must set or switch on a budget (Assistant > Budgets) before it can be used." Switching a budget back on restores it with the next question. A budget that is switched off, or whose limit is zero, does not count. A temporary "unlimited until" override does not take a budget out of force: it is a dated exception to a budget that stays in place.
+- **Scheduled tasks** are refused the same way, and the run's error is that sentence.
+- **The retention process** now ends a confirmed change that was left running for more than an hour as failed, "Outcome unknown: ... Check the record before asking for it again.", with a tool-call row. Such an action could not be confirmed again before either; it is now also removed after `approvalRetentionDays` like any other.
+- The assistant's own tables can never be opened to the assistant, by a row or by code.
+
+### Keeping the assistant read-only, or opening single tables
+
+In the application's configuration class, not in the database:
+
+```java
+config.withDefaultTableAccess(DataAccessMode.READ)        // the assistant proposes no change anywhere ...
+   .withTableAccess("orders", DataAccessMode.READ_WRITE)  // ... except where the code says so
+   .withTableAccess("payroll", DataAccessMode.NONE)       // never shown to the assistant, whoever asks
+   .withDefaultProcessAccess(DataAccessMode.NONE);        // no process, when the process tools arrive
+```
+
+A pin replaces the default for its object. An administrator's row can lower a pin or the default and can never raise either: with `withDefaultTableAccess(READ)` a `READ_WRITE` row does nothing.
+
+### Java API, for a host or another QBit that called these directly
+
+- `SignedInPerson.ofSession(qInstance, session)` returns a person whose `session()` is the session the authentication module resolved, not the object passed in. Code that put permissions, security keys or values on its own session object and expected the assistant to see them must put them where the authentication module does (its customizer). The time zone value is carried over.
+- `UiApiToolbox.Context.forRead(sessionUUID, timezone, gateway, policy, credentials, turnId)` is gone. `runtime.getToolCalls().readContext(person, timeout)` makes the context of one of the assistant's own reads, for a signed-in person, and throws `QException` when the person has no assistant access or the kill switch is on.
+- `StarterPrompts.forUser(person, policy, configured, historyOffered)` is gone; `forUser(context, userId, configured, historyOffered)` takes a context from `readContext`. `new StarterPrompts(toolbox, clock)` no longer takes a gateway.
+- `AssistantStore.expirePendingAction(id)` is `expirePendingAction(userId, id, now)` and returns whether it expired the action; `decidePendingAction` is final.
+- `UiApiToolbox.definitions(policy, boolean)` is `definitions(policy, Set<String> writableTables)`; `UiApiToolbox.anyWritableTable()` is gone (`DataAccessService.anyWritableTable()` still says whether any table's data access allows writes, for nobody in particular). `new BulkLoadToolFamily(bulkLoadTools)` takes one argument.
+- `AssistantRetentionStep.Result` has an eighth component, `pendingActionsFailed`; `purge(runtime, now)` is the whole run, `purge(config, store, now)` everything but ending the actions left running.
+- `processes.DataAccessDefaultsProcess` is gone.
+- The test-jar of `qbit-assistant` holds the `testing` package only. A project that used `RuntimeInternals`, `ToolCallServiceInternals` or `Toolboxes` from it (none of the provider modules did) keeps its own copy in its own test sources, inside the assistant's package it reaches into; they were never an API.
+- A host's own `ToolFamily` and its tools compile unchanged. A host's tool that proposes a change is offered as before; it decides its own offer in `definition(ToolOffer)`.
+
+### An existing test's expectation that changed
+
+`ChatToolSetTest` compares the chat's tool list with a file written before the tool registry existed. No definition changed and no line of the file changed. What changed is who is offered the write tools: the four "everything" scenarios now ask as a person who may change tables (with no settings row; they used to ask as a person who may only read, with `READ_WRITE` rows), and the scenario of a person who may not save an analysis lost its `save_analysis` line.

+-- qbit-assistant: writes follow the signed-in person's own permissions.
+--
+-- From this release the assistant may propose any change the signed-in person
+-- may make themselves, on every table, with no settings row: that default is
+-- declared in code (AssistantQBitConfig.withDefaultTableAccess, READ_WRITE),
+-- and an assistant_data_access row can only narrow it. A READ row therefore
+-- now means "the assistant never proposes a change to this table".
+--
+-- The retired table action "Add rows for every table" wrote the OLD default
+-- out as rows: one READ row per table that had none. Left in place, every one
+-- of them would now be read as an administrator's restriction and writes would
+-- stay off on those tables. This changeset removes those rows, and only those:
+-- rows of type TABLE, mode READ, that still carry the action's fixed note and
+-- were never changed after the action wrote them.
+--
+-- Include it from the host's master changelog, once, after the changesets that
+-- create the assistant_* tables:
+--
+--   - include: { file: db/liquibase/qbit-assistant/assistant-data-access-follow-user.changelog.sql }
+--
+-- What it never touches:
+--   * a row an administrator wrote (no note, or another note);
+--   * a row an administrator changed after the action wrote it (its mode, its
+--     note, or anything else: its modify date moved);
+--   * a NONE or READ_WRITE row, and every PROCESS row.
+-- Every row it leaves keeps its meaning and now reads as a restriction. The
+-- direction of any mistake is the safe one: a row wrongly kept leaves a table
+-- read-only for the assistant, which an administrator can see on
+-- Assistant > Data Access and delete.
+--
+-- "Never changed" is read from the dates: the application sets a row's create
+-- date and modify date in the same insert, a few microseconds apart, and moves
+-- the modify date on every later save. A row whose modify date is less than one
+-- second after its create date was not edited by a person.
+--
+-- Rules for this file, as for the starter defaults:
+--   * rollback is empty: a deleted row carried no decision of an administrator,
+--     and restoring it would switch writes off again;
+--   * portable SQL (PostgreSQL and H2);
+--   * a precondition on the table, so a host that has not created it yet simply
+--     skips the changeset (MARK_RAN).
