+# Agent Run Action Request Fix Plan
+
+## Reader And Outcome
+
+This plan is for a Xero engineer fixing the owned-agent approval and tool-run regressions exposed by the latest agent run audit.
+
+After reading it, the engineer should be able to implement the fixes, wipe affected dev app-data state as required by project policy, and run scoped regressions that prove this failure class cannot recur.
+
+## Problem Statement
+
+The latest owned-agent run produced several user-visible failures:
+
+- Approval cards rendered with Approve and Reject buttons, but clicking them did not resolve the underlying action.
+- Some shell command review events appeared as successful tool calls even though no command spawned.
+- `command_verify` rejected a valid package-manager script named `type-check`.
+- Operator/action errors were stored in state but not shown where the user was trying to act.
+- Invalid tool input was rendered like an approvable operator decision even though approval could not fix it.
+- The agent reasoned about missing or confusing tool availability instead of receiving clear stage/tool guidance.
+- File edit mismatches were recoverable, but noisy and not clearly separated from hard failures.
+- The target app update skipped at least one likely app surface, so the original “all apps” intent was not clearly completed.
+
+The root cause is not one isolated UI bug. The runtime, persistence, stream projection, frontend routing, command policy, and agent guidance each allow a different part of the bad experience.
+
+## Goals
+
+- Action-required events must carry durable action identity from backend persistence to frontend cards.
+- Approval and rejection buttons must route to the owned-agent action APIs when the card represents an owned-agent action.
+- Approving one card must not accidentally approve unrelated pending actions from the same run.
+- Pending command reviews must be displayed as pending review, not succeeded command executions.
+- Valid package-manager verification scripts such as `type-check` must pass the validator and policy allowlist.
+- Operator/action errors must be visible near the card or composer that triggered them.
+- Invalid tool input must render as a non-approvable diagnostic or failure state, not as an Approve/Reject card.
+- Agent stage and tool guidance must reduce confusion about available edit/command tools and package-manager workflows.
+- Scoped tests must cover the bad paths from the audited run.
+
+## Non-Goals
+
+- Do not add backwards-compatible migrations or glue for stale malformed dev state unless explicitly requested.
+- Do not create temporary debug UI.
+- Do not finish unrelated Tokenloom product work as part of this fix except where a fixture or regression test needs a representative monorepo scenario.
+- Do not rename on-wire `workflowStructure.phases` or other legacy DTO names while fixing Stages behavior.
+
+## Phase 1: Preserve Durable Action Identity
+
+Fix owned-agent `action_required` event emission so the stream can render real, resolvable cards.
+
+Relevant implementation areas:
+
+- `client/src-tauri/src/runtime/agent_core/persistence.rs`
+- `client/src-tauri/src/runtime/agent_core/tool_dispatch.rs`
+- `client/src-tauri/src/commands/subscribe_runtime_stream.rs`
+
+Tasks:
+
+- In `record_command_action_required`, append the same durable `actionId` that was inserted into `agent_action_requests`.
+- Include `actionType`, `title`, `detail`, and the decision shape needed by the frontend.
+- For command approval boundaries, use an explicit action type such as `command_approval`.
+- For safety-boundary policy denials, append the durable action id and use an explicit action type such as `safety_boundary`.
+- Include enough command context for the UI to display the exact pending command without inferring from a sibling tool call.
+- Stop inventing resolvable fallback ids like `owned-agent-action-{event_id}` for owned-agent action cards.
+- If a historical or malformed event has no durable action id, project it as a noninteractive diagnostic with clear copy instead of rendering live Approve and Reject buttons.
+
+Acceptance checks:
+
+- A newly emitted command-review event contains the same action id as its `agent_action_requests` row.
+- A newly emitted safety-boundary event contains the same action id as its `agent_action_requests` row.
+- The frontend never receives a clickable owned-agent action card without a durable action id.
+
+## Phase 2: Make Approve And Reject Action-Scoped
+
+Fix the backend and frontend path so each card resolves exactly the intended action.
+
+Relevant implementation areas:
+
+- `client/src-tauri/src/db/project_store/agent_core.rs`
+- `client/src-tauri/src/commands/agent_task.rs`
+- `client/src-tauri/src/runtime/agent_core/facade.rs`
+- `client/components/xero/agent-runtime.tsx`
+- `client/components/xero/agent-runtime/use-agent-runtime-controller.ts`
+
+Tasks:
+
+- Audit `answer_pending_agent_action_requests`, which currently resolves pending action requests by run rather than by specific action id.
+- Add an action-scoped answer path, or make existing owned-agent approval APIs require and honor `actionId`.
+- Ensure approving one card cannot approve every pending request in the run.
+- Ensure rejecting one card cannot reject unrelated pending requests.
+- Update the frontend action card routing to pass `runId`, `actionId`, and `actionType` to the owned-agent action APIs.
+- Keep operator-review actions separate from owned-agent actions so cards do not silently route to `resolve_operator_action`.
+- Add stale-run reconciliation so a paused run with pending action requests is still resolvable even if the supervisor row is marked stale.
+- If a run cannot be resumed because runtime state is truly stale, show a direct error and recovery action instead of leaving buttons inert.
+
+Acceptance checks:
+
+- Approving one of two pending action cards resolves only that card's row.
+- Rejecting one of two pending action cards resolves only that card's row.
+- A paused run with pending action requests can be resumed or produces a visible recovery error.
+- No owned-agent action card calls the operator-review mutation path.
+
+## Phase 3: Surface Action Errors Where The User Acts
+
+The audited UI had errors in state, but the user could not see them from the card or composer.
+
+Relevant implementation areas:
+
+- `client/src/features/xero/use-xero-desktop-state/operator-auth-mutations.ts`
+- `client/components/xero/agent-runtime/use-agent-runtime-controller.ts`
+- `client/components/xero/agent-runtime.tsx`
+
+Tasks:
+
+- Thread `operatorActionError` and owned-agent action errors through the runtime controller.
+- Render action failure feedback inline on the relevant card when possible.
+- Also expose the latest action error in the composer area if the card has scrolled away.
+- Clear stale action errors after a successful retry or when a different action is selected.
+- Avoid generic silent failures; include the backend reason if it is safe and user-actionable.
+
+Acceptance checks:
+
+- A failed Approve click shows visible feedback without requiring logs.
+- A failed Reject click shows visible feedback without requiring logs.
+- Retrying after fixing the cause clears the old error.
+
+## Phase 4: Correct Command Review Display Semantics
+
+Some command-review events were marked successful even though the command never spawned.
+
+Relevant implementation areas:
+
+- `client/src-tauri/src/commands/subscribe_runtime_stream.rs`
+- `client/components/xero/agent-runtime.tsx`
+
+Tasks:
+
+- Treat command tool results with `spawned=false`, `exitCode=null`, and a review/escalation outcome as pending review.
+- Do not render those tool completions as successful executions.
+- Collapse or visually associate the pending command tool event with its action-required card so the stream does not show both a green success and a pending approval for the same command.
+- Preserve true success styling only for commands that actually spawned and exited successfully.
+- Preserve true failure styling for commands that spawned and returned nonzero.
+
+Acceptance checks:
+
+- A command waiting for approval is labeled as needing review.
+- A command waiting for approval has no green success affordance.
+- A spawned command with exit code 0 still renders as succeeded.
+- A spawned command with nonzero exit code still renders as failed.
+
+## Phase 5: Accept Safe `type-check` Verification Scripts
+
+The audited target repo used `type-check`, and direct package-manager execution passed. Xero rejected the script before it could run.
+
+Relevant implementation areas:
+
+- `client/src-tauri/src/runtime/agent_core/types.rs`
+- `client/src-tauri/src/runtime/autonomous_tool_runtime/policy.rs`
+
+Tasks:
+
+- Add `type-check` to the safe package-manager verification names.
+- Keep `typecheck` accepted.
+- Keep `test`, `tests`, `lint`, `check`, and `build` behavior unchanged.
+- Decide whether scoped variants such as `type-check:ci` are safe. If supported, implement intentionally and test them; otherwise reject them with clear copy.
+- Update validator error text so it lists both `typecheck` and `type-check`.
+- Keep the command verification validator and the autonomous tool policy allowlist aligned.
+
+Acceptance checks:
+
+- `pnpm --filter <pkg> type-check` validates.
+- `pnpm --filter <pkg> run type-check` validates if the existing validator supports `run` script form.
+- Equivalent npm and yarn safe script forms validate where currently supported.
+- Unsafe package scripts remain rejected.
+
+## Phase 6: Render Invalid Tool Input As A Diagnostic
+
+`agent_action_tool_input_invalid` is not fixed by user approval, so it should not look like an approvable action.
+
+Relevant implementation areas:
+
+- `client/src-tauri/src/runtime/agent_core/tool_dispatch.rs`
+- `client/src-tauri/src/commands/subscribe_runtime_stream.rs`
+- `client/components/xero/agent-runtime.tsx`
+
+Tasks:
+
+- Classify invalid tool input separately from action-required approval boundaries.
+- Render invalid tool input as a failed tool-call diagnostic with the validation message.
+- If the run pauses on invalid input, explain that the next agent turn must retry with corrected input.
+- Do not show Approve and Reject buttons for invalid tool input.
+- Avoid storing invalid input events as pending `agent_action_requests` unless there is a real decision the operator can make.
+
+Acceptance checks:
+
+- An invalid `command_verify` input displays as a validation failure.
+- The card has no Approve or Reject buttons.
+- The run state and UI copy agree on whether the agent can continue.
+
+## Phase 7: Reduce Agent Tool Confusion
+
+The agent reasoned about missing or surprising tools because the stage prompt and available tools were not explained clearly enough.
+
+Relevant implementation areas:
+
+- `client/src-tauri/src/db/migrations.rs`
+- Runtime prompt or stage-policy generation for Engineer mode.
+- Any tests covering Stages tool allowlists.
+
+Tasks:
+
+- Update Engineer stage guidance to clearly explain available edit tools in the current runtime.
+- If `patch` is intentionally unavailable, say so through tool instructions and explain the expected `edit` or `write` workflow.
+- Make command stages explicit: `command_verify` is for verification commands; package-manager mutation commands need the appropriate reviewed command path.
+- Add lockfile guidance: when package manifests change, the agent should use the package manager to update the lockfile through an approved command rather than hand-editing it.
+- Keep user-facing terminology as "Stages" and avoid introducing "workflow phases" in UI copy.
+
+Acceptance checks:
+
+- A new run receives clear tool guidance before the first edit or command decision.
+- The agent no longer needs to infer why `patch` is unavailable.
+- Package manifest changes trigger a clear lockfile update path.
+
+## Phase 8: Add Target-Scope Completion Guardrails
+
+The audited run changed web, landing, and admin surfaces, but did not clearly resolve whether mobile was in scope.
+
+Relevant implementation areas:
+
+- Agent instructions/prompt planning for implementation tasks.
+- E2E or integration fixture representing a multi-app workspace.
+
+Tasks:
+
+- Add a representative fixture or scripted scenario for a monorepo with shared UI, web, landing, admin, and mobile surfaces.
+- Ensure the agent records which app surfaces are in scope before claiming "all apps" are complete.
+- If a surface is incompatible with the chosen implementation, the agent must either implement the compatible alternative or explicitly report that it was not changed.
+- Ensure final responses distinguish verified surfaces from skipped surfaces.
+
+Acceptance checks:
+
+- A multi-app request cannot be marked complete while silently skipping a likely app surface.
+- Verification output names the surfaces actually tested.
+
+## Phase 9: Wipe Affected Dev App-Data State Before Final QA
+
+Project policy prohibits compatibility glue for stale state in this new app unless explicitly requested.
+
+Tasks:
+
+- After code fixes are in place, wipe the affected state under `~/Library/Application Support/dev.sn0w.xero`.
+- Prefer the narrowest affected project state wipe if enough context is known.
+- Use only `Support/dev.sn0w.xero` data during development.
+- Do not use `.xero/` repo-local state for new project state.
+- Reproduce the audited failure class from fresh dev app-data.
+
+Acceptance checks:
+
+- Fresh dev app-data produces durable action ids on new action-required events.
+- No stale malformed action cards remain after reset.
+- No compatibility migration was added for the malformed dev-only action events.
+
+## Testing Checklist
+
+Run scoped tests only.
+
+- Rust tests for action-required persistence payloads.
+- Rust tests for stream projection of owned-agent action cards.
+- Rust tests for action-scoped approval and rejection.
+- Rust tests for `type-check` command verification and unsafe script rejection.
+- Frontend tests for owned-agent Approve and Reject routing.
+- Frontend tests for inline action error display.
+- Frontend tests for pending command review display.
+- Integration smoke test for a paused owned-agent run with a pending command approval.
+- Integration smoke test for invalid tool input rendering as a diagnostic.
+- Manual Tauri QA in development data if automated UI coverage cannot cover the full resume path.
+
+## Final Acceptance Criteria
+
+- The screenshot failure class no longer reproduces: Approve and Reject do something visible and correct.
+- Every clickable owned-agent action card has a durable action id.
+- Clicking Approve or Reject mutates exactly the intended pending action row.
+- Command approvals do not render as successful command executions before spawning.
+- `type-check` verification scripts are accepted by both validator and policy.
+- Invalid tool input is shown as a validation failure, not an approval request.
+- Action errors are visible to the user without reading logs.
+- Fresh dev app-data verifies the fixed behavior.
+- Scoped tests and formatting relevant to touched files pass.
+
+## Risks And Open Questions
+
+- The current run-level approval path may have been intentionally broad. If so, the product needs an explicit "approve all pending actions" affordance rather than making individual cards behave that way.
+- Resuming a paused run whose supervisor state is stale may need a small reconciliation layer before action resolution. Keep this narrow and observable.
+- Decide whether command approval should replay the exact pending command or only resume the model with the approval answer. The safer behavior is to bind approval to the exact stored command request.
+- Decide whether `type-check:*` script names are safe enough to allow. Avoid broad wildcard script approval unless there is a clear policy reason.
+- Historical malformed action events can remain noninteractive diagnostics after dev app-data reset. Do not add backwards compatibility code for stale development state unless explicitly requested.

-# Computer Use System Control Audit And Expansion Plan
-
-## Reader And Goal
-
-Reader: an internal engineer expanding Xero Computer Use agent control.
-
-Post-read action: implement the missing agent-visible tools and platform capabilities needed for the user to control their own macOS or Windows machine by prompting, with explicit local consent, visible control state, auditability, and no attempts to bypass OS security boundaries.
-
-## Audit Conclusion
-
-Computer Use already has a real agent-control foundation. It can use ordinary agent tools for project inspection, file changes, commands, browser control, diagnostics, skills, subagents, durable context, and external capabilities. It also has a native desktop-control foundation: observe the desktop, send pointer and keyboard input, launch or target apps, manage a desktop stream, and audit control actions.
-
-This plan is not mainly about manual WebRTC control. Manual streaming and human viewport control are one client of the desktop broker. The main target is LLM-driven Computer Use: the agent should have the right prompt-visible tools, schemas, permissions, policy gates, and platform backends to operate the user's computer as completely as the user explicitly allows.
-
-macOS is substantially deeper than Windows because it has Accessibility, Vision OCR, ScreenCaptureKit WebRTC streaming, and app/window automation fallbacks. Windows currently has useful pointer, keyboard, clipboard, screenshot, window, and app basics, but it lacks structured UI Automation, OCR, and native WebRTC video publishing.
-
-The current surface is not "absolute full system control" yet. Prompted desktop control is still bounded by:
-
-- OS permissions such as Screen Recording, Accessibility, Input Monitoring, Windows session access, and UAC.
-- Xero policy gates that deny secret text, credential managers, payments, financial flows, identity verification, MFA/recovery flows, and system privacy/security settings.
-- Repo-scoped command tools rather than a general host-administration shell.
-- Agent-visible schemas that omit a few lower-level actions already implemented in the runtime.
-- Tool activation and effective-policy gaps where the Computer Use agent can theoretically use a capability, but it is not present, clear, or available in the current turn.
-
-The right expansion path is to add an explicit owner-approved power mode, close the prompt-visible schema gaps, bring Windows to parity with macOS structured control, then add audited host-administration tools where the local user grants the privilege.
-
-## Scope: Agent-Driven Control
-
-The product goal is not only "let a remote human click the streamed desktop." It is "let the Computer Use agent complete computer tasks by choosing the best tool."
-
-That means the audit must cover four layers:
-
-- Agent policy: whether Computer Use is allowed to use a tool at all.
-- Tool activation: whether the tool is included in the current turn or discoverable through tool access.
-- Tool schema: whether the LLM can see every action and field it needs.
-- Platform backend: whether macOS and Windows can actually execute the requested action.
-
-Manual WebRTC control belongs mostly to the platform backend and streaming layers. LLM-driven control also needs browser tools, file tools, command tools, process tools, system diagnostics, MCP tools, skills, subagents, project context, and future host-administration tools.
-
-## Current Computer Use Agent Tool Surface
-
-Computer Use is defined as a general-purpose runtime agent. Its base prompt says it may combine computer interaction, project inspection, file changes, commands, browser and desktop automation, diagnostics, external-capability tools, skills, subagents, and durable context when those tools are available and appropriate.
-
-The runtime agent gate broadly allows Computer Use to use the available autonomous tool catalog. The practical availability still depends on per-run tool policy, tool-access activation, feature rollout flags, provider schema limits, and platform support.
-
-### Agent Tools Already Covered
-
-- Repository and workspace observation: read, read-many, stat, search, find, list, tree listing, directory digest, file hash, git status, git diff, workspace index, code intelligence, and LSP.
-- Repository mutation: edit, write, patch, copy, structured file transactions, JSON/TOML/YAML edit, delete, rename, mkdir, and notebook edit where available.
-- Command and process control: command probe, command verify, command run, command session, and process manager.
-- Browser/web control: browser observe, browser control, web fetch, and web search where enabled.
-- Desktop control: macOS automation, desktop observe, desktop control, and desktop stream.
-- System diagnostics: observe diagnostics and approval-gated privileged diagnostics.
-- External extension surfaces: MCP list/read/get/call, dynamic MCP tools, skills, and subagents.
-- Coordination and memory: todo, project context search/get/record/update/refresh, environment context, and agent coordination.
-- Domain tools: emulator and Solana tools when the selected app/tool profile exposes them.
-
-### Agent Tool Gaps
-
-- There is no explicit capability matrix that says which Computer Use tools are active by default, available through tool-access request, blocked by policy, blocked by rollout, or blocked by platform.
-- The current desktop-control audit covers native desktop tools more thoroughly than non-desktop agent tools.
-- Repo-scoped command tools are powerful for development tasks, but they are not a complete host-administration surface.
-- PowerShell appears as a tool constant/category, but the plan must verify whether it is fully agent-visible, cross-platform, policy-gated correctly, and sufficient for Windows administration.
-- Browser control, desktop control, command tools, and host administration need clearer routing rules so the agent chooses the most precise safe tool instead of falling back to pixel control.
-- Dynamic MCP, skills, and subagents can extend control, but there is no required "Computer Use workstation pack" that guarantees the expected macOS and Windows capabilities are installed.
-
-## Current Desktop Tool Surface
-
-### Generic Desktop Observation
-
-The `desktop_observe` tool is agent-visible and exposes:
-
-- `permissions_status`
-- `display_list`
-- `window_list`
-- `app_list`
-- `foreground_state`
-- `screenshot`
-- `cursor_state`
-- `accessibility_snapshot`
-- `ocr_snapshot`
-- `element_at_point`
-- `health`
-
-It supports display targeting, window targeting, screenshot regions, and coordinates for element lookup.
-
-### Generic Desktop Control
-
-The `desktop_control` tool is agent-visible and exposes:
-
-- Pointer: `mouse_move`, `mouse_click`, `mouse_double_click`, `mouse_right_click`, `mouse_drag`, `scroll`
-- Keyboard and text: `key_press`, `hotkey`, `type_text`, `paste_text`
-- App/window: `focus_window`, `activate_app`, `launch_app`, `quit_app`
-- Structured UI: `ax_press`, `ax_set_value`, `ax_focus`, `menu_select`
-- Safety/control: `cancel_current_action`
-
-The runtime also supports `mouse_down`, `mouse_drag_move`, and `mouse_up`, but those are not in the current agent-visible schema. They appear intended for lower-level/manual-control paths.
-
-### Desktop Streaming
-
-The `desktop_stream` tool is agent-visible and exposes:
-
-- `stream_capabilities`
-- `stream_start`
-- `stream_stop`
-- `stream_status`
-- `stream_set_quality`
-- `stream_request_keyframe`
-
-The runtime and sidecar also support WebRTC offer, answer, and ICE candidate operations, but those signaling operations are not currently in the agent-visible schema.
-
-### macOS-Specific Automation
-
-The `macos_automation` tool exposes:
-
-- `mac_permissions`
-- `mac_app_list`
-- `mac_app_launch`
-- `mac_app_activate`
-- `mac_app_quit`
-- `mac_window_list`
-- `mac_window_focus`
-- `mac_screenshot`
-
-It is macOS-only. App quit requires operator approval. On macOS, generic desktop app/window actions can fall back through this path when the sidecar does not implement those operations directly.
-
-## macOS Capability Matrix
-
-### macOS: Present
-
-- Permission status for Screen Recording, Accessibility, and Input Monitoring.
-- Display, window, app, and foreground-state observation.
-- Full-display and region screenshots.
-- Cursor position.
-- Accessibility snapshot and element-at-point through macOS Accessibility.
-- OCR snapshot through macOS Vision.
-- Mouse move, down, up, click, double-click, right-click, drag, drag-move, and scroll in the runtime/sidecar.
-- Key press, hotkey, and typed text.
-- Clipboard-backed paste through the sidecar.
-- Accessibility actions: press, set value, focus.
-- Menu path selection through Accessibility.
-- App launch, activation, quit, and window focus through macOS app automation.
-- Native WebRTC desktop stream using ScreenCaptureKit and VideoToolbox H.264.
-- Screenshot fallback stream state.
-- Controller lock, local-user takeover detection, audit log, sidecar token auth, and sidecar integrity checks.
-
-### macOS: Missing Or Weak
-
-- Agent-visible schema does not expose `mouse_down`, `mouse_up`, `mouse_drag_move`, `sourceWidth`, or `sourceHeight`.
-- Agent-visible stream schema does not expose WebRTC signaling actions, even though the runtime supports them.
-- Accessibility control is narrow: press, set value, focus, and menu select only. It lacks common AX actions such as select, confirm, cancel, increment/decrement, expand/collapse, scroll-to-visible, table/list row selection, checkbox/radio state changes, and robust text-field editing helpers.
-- Element identity is not yet a durable targeting contract. A prompt can use snapshots, but stable element references across app refreshes need stronger IDs and re-resolution.
-- Keyboard input depends on a fixed key map. International layouts, dead keys, IME text, media keys, function layers, and secure input mode need explicit handling.
-- Clipboard is write/paste oriented. There is no general read/write clipboard API for text, images, files, or rich formats.
-- No first-class Dock, menu bar extra, Mission Control, Spaces, notification, file dialog, open/save panel, or drag-and-drop file automation.
-- No general system-administration bridge for host-level operations outside the repo sandbox.
-- No privileged control for settings, network, display, audio, services, package managers, login items, or app install/uninstall beyond what can be clicked manually.
-- No supported path to bypass TCC, SIP, secure input, password prompts, or other OS-protected boundaries. Those must remain user-mediated.
-
-## Windows Capability Matrix
-
-### Windows: Present
-
-- Display, window, app, and foreground-state observation through `xcap`.
-- Full-display and region screenshots through `xcap`.
-- Cursor state through the sidecar input backend.
-- Mouse move, down, up, click, double-click, right-click, drag, drag-move, and scroll through Enigo.
-- Key press, hotkey, and typed text through Enigo.
-- Clipboard-backed paste through `arboard` plus Ctrl+V.
-- Window focus and app activation through Win32 calls wrapped in PowerShell.
-- App launch through PowerShell and the Windows AppsFolder shell namespace.
-- App quit through `taskkill.exe`.
-- Static permissions model that treats screen capture and desktop input as granted in the active user session.
-- Screenshot fallback stream state.
-- Controller lock and audit flow shared with macOS.
-
-### Windows: Missing Or Weak
-
-- No Windows UI Automation tree, element-at-point implementation, or structured element actions.
-- No OCR snapshot implementation.
-- No menu selection implementation.
-- No native WebRTC desktop video publisher. The current native publisher is macOS-only; Windows falls back to screenshot-based degraded mode.
-- Window management is basic: focus/activate/launch/quit only. There is no maximize, minimize, restore, move, resize, close-window message, virtual desktop, monitor move, z-order control, or owner-drawn app targeting contract.
-- App launching is heuristic. It does not yet model Store apps, protocol handlers, file associations, shell verbs, admin launches, or installed-app inventory robustly.
-- UAC and secure desktop are not controllable. Elevated actions require explicit user approval through the OS.
-- No Registry, Services, Task Scheduler, Event Log, Windows Settings, firewall, network adapter, winget, MSI, process privilege, or local user/group management tool.
-- No RDP/session switching, lock screen, credential provider, session 0, or secure-input support.
-- No deep browser/Office/Explorer-specific structured automation beyond generic screen and input.
-
-## Cross-Platform Policy And Safety Boundaries
-
-Current desktop-control policy intentionally blocks:
-
-- Secret text typing or pasting.
-- Password managers, Keychain, credentials, passkeys, and saved-password contexts.
-- Purchases, checkout, payment confirmation, money transfer, and card entry.
-- Banking, brokerage, tax, payroll, insurance, crypto, and wallet contexts.
-- Identity verification, KYC, passport, driver license, SSN, and account ownership flows.
-- MFA, TOTP, OTP, recovery codes, account recovery, password reset, and security settings.
-- System privacy and security settings.
-
-These boundaries conflict with literal "absolute full control," but they are the right default for a shipped product. Expansion should add an explicit local owner/admin mode rather than silently weakening default Computer Use policy.
-
-## Expansion Plan
-
-### Phase 0: Agent Tool Access Manifest
-
-Goal: make Computer Use's LLM-accessible tool surface explicit before expanding any backend.
-
-Tasks:
-
-- Generate or maintain a Computer Use capability manifest that lists every tool, action, schema field, risk class, default availability, tool-access availability, rollout gate, platform gate, and approval requirement.
-- Add tests that fail when the runtime action enum, agent-visible schema, tool catalog metadata, TypeScript DTOs, and provider schema projection drift apart.
-- Verify that Computer Use can activate the expected non-desktop tool families: repository read/write, command/session/process, browser observe/control, web fetch/search, diagnostics, MCP, skill, subagent, todo, project context, environment context, code intelligence, and domain tools.
-- Add a "best tool selection" guide to the Computer Use prompt or tool descriptions: prefer structured browser tools for browser tasks, command/process tools for shellable tasks, native desktop structured actions for app UI, and pixel input only when no more precise tool exists.
-- Add a visible status/debug surface for developers that explains why a tool is missing in a run: policy, provider limit, rollout flag, platform unsupported, permission denied, not activated, or not installed.
-- Define the required "workstation control pack" for macOS and Windows: desktop sidecar, browser control, host command/admin tools, clipboard/file-drop tools, OCR/UI tree support, and diagnostics.
-
-Acceptance criteria:
-
-- An engineer can answer "what can the Computer Use agent do on this machine right now?" from one manifest.
-- A prompt-visible Computer Use tool cannot silently disappear without a failing test or visible availability reason.
-- Manual WebRTC controls and LLM-driven tools are documented as separate surfaces sharing some desktop broker backends.
-
-### Phase 1: Make Implemented Actions Prompt-Visible
-
-Goal: expose the actions that already exist in the runtime where doing so improves prompted control.
-
-Tasks:
-
-- Add `mouse_down`, `mouse_up`, and `mouse_drag_move` to the `desktop_control` agent schema, tool catalog metadata, TypeScript DTOs, tests, and provider schema tests.
-- Add `sourceWidth` and `sourceHeight` to the `desktop_control` agent schema so prompted actions can target screenshots or streams rendered at non-native sizes.
-- Decide whether stream signaling remains internal or becomes prompt-visible. If prompt-visible, expose `stream_offer`, `stream_answer`, and `stream_ice_candidate` with strict SDP/ICE validation.
-- Add focused runtime tests proving the schema and action enum stay aligned.
-- Update the manual-control drag plan if the frontend still lacks the stateful gesture path.
-
-Acceptance criteria:
-
-- Every runtime desktop action intentionally available to agents is present in the tool schema.
-- Hidden/internal actions are documented as internal, not accidentally omitted.
-- Pointer press-hold-release can be driven by prompt when the local policy allows it.
-
-### Phase 2: Windows Structured UI Parity
-
-Goal: make Windows controllable by elements, not only pixels.
-
-Tasks:
-
-- Add a Windows UI Automation backend in the sidecar.
-- Implement `accessibility_snapshot` from UIA trees with role, name, value, state, bounds, enabled/focused, and provider diagnostics.
-- Implement `element_at_point` through UIA hit testing.
-- Implement `ax_press`, `ax_set_value`, and `ax_focus` through UIA patterns such as Invoke, Value, Text, SelectionItem, Toggle, ExpandCollapse, and ScrollItem.
-- Implement `menu_select` through UIA menu traversal where possible, with a fallback to Alt-key menu navigation.
-- Add stable element handles that can be re-resolved from snapshot rows without trusting stale raw handles.
-- Add Windows-specific tests behind target cfg gates and sidecar contract tests with mocked UIA payloads.
-
-Acceptance criteria:
-
-- A prompt can inspect a Windows app's UI tree, select a visible element, and invoke or edit it without coordinate clicking when UIA supports it.
-- Unsupported controls return actionable diagnostics instead of falling back silently.
-- The existing pointer/keyboard path remains available when UIA is blocked or absent.
-
-### Phase 3: Windows OCR And Native Streaming
-
-Goal: make Windows observation comparable to macOS for visual and remote-control tasks.
-
-Tasks:
-
-- Implement OCR with Windows.Media.Ocr where available, with a fallback strategy for unsupported Windows versions.
-- Return OCR blocks with text, bounds, confidence, full text, truncation, and diagnostics matching the current sidecar contract.
-- Implement native WebRTC publishing on Windows with Windows Graphics Capture plus Media Foundation or a proven H.264 encoder path.
-- Preserve screenshot fallback as degraded mode, but avoid sharing a rate budget with critical input commands.
-- Add GPU/driver failure diagnostics and software fallback messaging.
-
-Acceptance criteria:
-
-- Windows can return OCR snapshots from display/region captures.
-- Windows can publish a native WebRTC desktop video track with cursor inclusion where supported.
-- Fallback behavior is explicit and does not mask input failures.
-
-### Phase 4: macOS Structured Control Completion
-
-Goal: expand macOS Accessibility from basic actions to a practical app-control API.
-
-Tasks:
-
-- Add AX action support for select, confirm/cancel, increment/decrement, expand/collapse, scroll-to-visible, list/table row selection, checkbox/radio toggles, and text range editing.
-- Add menu bar, Dock, status item, open/save panel, and file dialog helpers.
-- Add element re-resolution by app, window, role, title, bounds, and ancestry path.
-- Add keyboard-layout-aware key translation and a paste-first text path for long or non-US text.
-- Add clipboard read/write support for text, images, files, and common rich payloads with redaction controls.
-
-Acceptance criteria:
-
-- A prompt can operate ordinary macOS forms, menus, dialogs, lists, tables, and toggles without relying only on screen coordinates.
-- Text input works across keyboard layouts and long text.
-- Sensitive clipboard payloads are never persisted in audit logs.
-
-### Phase 5: Owner-Approved Host Administration Mode
-
-Goal: provide as much whole-system control as possible for an explicitly consenting local owner without making default Computer Use unsafe.
-
-Tasks:
-
-- Add a "Power User" or "Owner Admin" mode in desktop-control settings. It must be local-only, time-bound, visibly active, and revocable with emergency stop.
-- Add policy profiles: default safe, developer workstation, and owner admin.
-- Add an audited host command tool separate from repo-scoped commands. It should require explicit mode enablement and support shell, PowerShell, AppleScript/JXA, Shortcuts, `brew`, `winget`, service management, registry edits, package install/uninstall, app launch arguments, and host file operations.
-- Require per-command preview for destructive, privileged, network/security, startup-item, credential-adjacent, or privacy-sensitive operations.
-- Use OS-native elevation prompts when needed. Do not attempt to bypass UAC, TCC, SIP, secure desktop, or credential prompts.
-- Add rollback metadata where practical: changed files, registry keys, service state, package operations, and settings snapshots.
-
-Acceptance criteria:
-
-- A local owner can prompt Xero to perform broad workstation administration after enabling owner-admin mode.
-- The user can see, stop, and audit all high-impact actions.
-- Xero never claims it can bypass OS protections; it asks the user to approve OS prompts when required.
-
-### Phase 6: Desktop Resource Surfaces
-
-Goal: cover common real desktop work that is not just clicking.
-
-Tasks:
-
-- Add clipboard read/write actions for text, images, files, and common rich formats.
-- Add file drag/drop synthesis for apps that expect dropped files.
-- Add notification observation where platform APIs permit it.
-- Add audio volume, media keys, display arrangement/readout, and window layout helpers.
-- Add app inventory and launch-target discovery on both platforms.
-- Add browser and terminal bridge affordances that hand off to existing browser/control/command tools when they are more precise than desktop pixels.
-
-Acceptance criteria:
-
-- Computer Use can complete routine app workflows involving files, clipboard, dialogs, notifications, and window layout.
-- The agent prefers structured/native actions over coordinate input when available.
-
-### Phase 7: Verification Matrix
-
-Goal: make expanded control dependable across real machines.
-
-Tasks:
-
-- Add a capability-report fixture per platform that records sidecar capabilities, permission states, and known unavailable surfaces.
-- Test macOS with Screen Recording denied/granted, Accessibility denied/granted, Input Monitoring denied/granted, multiple displays, Retina scaling, and secure input.
-- Test Windows with standard user, administrator, UAC prompt, multiple DPI scales, multiple monitors, RDP, Store app, classic Win32 app, Electron app, browser, Explorer, and Office-style apps.
-- Add failure-mode tests for sidecar unavailable, sidecar operation unimplemented, screenshot capture denied, UIA unavailable, OCR unavailable, stream start failure, and local-user takeover.
-- Keep Cargo tests scoped and run one Cargo command at a time.
-
-Acceptance criteria:
-
-- The app can report exactly what a machine supports before the agent acts.
-- Platform-specific failures produce user-actionable messages.
-- High-risk actions are covered by approval, audit, and emergency-stop tests.
-
-## Final Target State
-
-The practical target is not stealthy or permissionless control. The target is consented, visible, owner-controlled workstation automation:
-
-- Observe the screen, UI tree, OCR text, windows, apps, cursor, permissions, and stream state.
-- Choose among browser, command, file, process, diagnostics, MCP, skill, subagent, and desktop tools based on the task.
-- Control pointer, keyboard, text, clipboard, menus, dialogs, windows, apps, and structured UI elements.
-- Stream the desktop reliably on macOS and Windows.
-- Administer the host through an explicit owner-approved tool surface.
-- Preserve audit logs, leases, emergency stop, and policy profiles.
-- Respect OS security prompts and refuse to bypass protected boundaries.

+# Agent Routing And Handoff
+
+Xero route suggestions use a single assistant marker:
+
+```xml
+<xero-routing-suggestion target="engineer" reason="short rationale" summary="one-sentence carry-over summary"/>
+```
+
+Custom-agent targets use `targetKind="custom"` and a definition id:
+
+```xml
+<xero-routing-suggestion targetKind="custom" definitionId="release_helper" reason="short rationale" summary="one-sentence carry-over summary"/>
+```
+
+Built-in route targets are limited to `ask`, `plan`, `engineer`, `debug`, and `generalist`. `computer_use`, `crawl`, and `agent_create` are excluded from route suggestions and cross-agent handoff.
+
+Plan is intentionally narrow: it may route or hand off only to built-in Engineer. It must not target Ask, Debug, Generalist, custom agents, Computer Use, Crawl, or Agent Create.
+
+Custom agents store the current handoff contract in `handoffPolicy`:
+
+```json
+{
+  "enabled": true,
+  "routingMode": "same_agent",
+  "allowedTargets": [],
+  "preserveDefinitionVersion": true,
+  "carrySummary": true,
+  "includeDurableContext": true
+}
+```
+
+`routingMode: "same_agent"` allows continuation under the same pinned agent definition only. `routingMode: "suggest"` allows cross-agent suggestions, but only to explicit `allowedTargets`.
+
+Allowed target refs are typed:
+
+```json
+{ "kind": "built_in", "runtimeAgentId": "engineer" }
+{ "kind": "custom", "definitionId": "release_helper", "version": 3 }
+```
+
+Custom-agent built-in targets may include Ask, Engineer, Debug, or Generalist. Plan and the excluded runtime agents are rejected as configurable custom-agent targets.

+# Agent Stale-File Protection
+
+This document is for engineers adding or reviewing agent-accessible mutation paths. After reading it, you should know which paths can change project files, what stale-file guard they use, and what contract new file mutations must follow.
+
+## Contract
+
+Owned agents must observe current file content before mutating an existing file. The observation can come from `read`, `read_many`, `search`, `find`, `list`, `list_tree`, `directory_digest`, `file_hash`, or a successful prior mutation output in the same run. Runtime preflight rejects owned-agent writes when an existing file has not been observed or when the file hash no longer matches the last observation.
+
+Every owned-agent existing-file mutation must also carry a content guard in the tool request. Use `expectedHash` for direct file mutations and `expectedSourceHash` for copy source files. Create-only writes to missing files do not need a hash and must reject an `expectedHash`, because there is no existing file snapshot to guard.
+
+Stale tool-level failures use stable code `autonomous_tool_stale_file` and include `currentHash` plus a required action to re-read current file evidence before retrying. Missing owned-agent hash guards use `autonomous_tool_expected_hash_required` and also include the current hash. Agent preflight can additionally fail with `agent_file_write_requires_observation` or `agent_file_changed_since_observed`; both require a fresh read/hash before retry.
+
+Reservations are advisory ownership leases, not content freshness. A reservation now records `observedHash` and `observedAt` for existing regular files at claim time so reviewers can compare coordination ownership with the content snapshot, but reservation presence never replaces `expectedHash`.
+
+## Mutation Inventory
+
+| Path | Protection status |
+| --- | --- |
+| `edit` | Mandatory for owned-agent applies: `expectedHash` on existing file, optional line hashes, runtime observation preflight. Preview validates provided hashes but does not require one. |
+| `write` | Mandatory for owned-agent overwrites: `expectedHash`, explicit `overwrite=true`, runtime observation preflight. Create-only missing-file writes are allowed without a hash. |
+| `patch` | Mandatory for owned-agent applies: each operation must include `expectedHash`; multi-file plans validate all files before any write and roll back earlier file writes if persistence fails. |
+| `json_edit`, `toml_edit`, `yaml_edit` | Mandatory for owned-agent applies: parser-backed edit requires `expectedHash` and runtime observation preflight. |
+| `notebook_edit` | Mandatory for owned-agent applies: notebook file `expectedHash`; optional `expectedSource` is only a cell-level extra guard. |
+| `delete` | Mandatory for owned-agent file deletes: `expectedHash`. Directory deletes use preview-derived `expectedDigest`. |
+| `rename` | Mandatory for owned-agent file sources: `expectedHash`. Existing file targets require `expectedTargetHash` before overwrite. |
+| `copy` | Mandatory for owned-agent file copies: `expectedSourceHash` for source file content and `expectedTargetHash` for existing file targets. Directory copies use preview-derived `expectedSourceDigest`. |
+| `fs_transaction` | Mandatory for owned-agent apply operations through the underlying operation guards. Planning validates stale hashes before backup/write. Apply uses rollback backups and reports rollback status if an operation fails after mutation starts. |
+| `mkdir` | Create-only directory mutation; no file content hash applies. Runtime path/epoch preflight still covers owned-agent path intent. |
+| Command/shell tools | Not hash-guarded because the runtime cannot inspect arbitrary command semantics. Command policy separates probe/verify/general execution, and command results with changed files invalidate matching observed hashes; truncated changed-file reports clear all observed hashes. |
+| MCP tool invocation | External capability invocation is policy-gated but content-hash protection is not mandatory because MCP tools are opaque. Treat MCP mutations like command mutations: re-read/hash files before later structured writes. |
+| Project editor saves and code-history undo/revert | Human/system-side mutations advance code workspace history and invalidate overlapping reservations. Owned agents must acknowledge/refresh workspace epoch and re-read files before writing. |
+| Agent definition and workflow definition writes | App-data definition mutations, not repo file edits. They are schema-validated and audit-recorded; repo stale-file hashes do not apply. |
+| Project context, mailbox, todo, coordination writes | App-data state mutations, not repo file edits. They are protected by app-data validation and TTL/audit semantics rather than project-file hashes. |
+
+## Retry Rule
+
+Never retry a stale write by changing only the hash value from an error message. The agent must call `read`, `read_many`, or `file_hash` for the affected path, reconcile the current content with the intended change, then retry with the new guard. This protects against human edits, sibling-agent edits, command mutations, history undo/revert, and stale app-data snapshots.

+# Context Exhaustion, Compaction, And Handoff Strategy
+
+## Reader And Action
+
+This document is for Xero engineers changing owned-agent continuity behavior. After reading it, an engineer should be able to implement or review a compaction and handoff model-routing change without weakening current continuity, privacy, or cost controls.
+
+## Recommendation
+
+Add an opt-in continuity model routing policy, then make it the default only after evals prove it is better than active-provider compaction. The recommended shape is a routing policy that can use a fast, large-context model for compaction and handoff summaries, with an explicit user override and an active-provider fallback.
+
+Do not add a hidden provider that silently bypasses the user's active profile. Compaction sees raw conversation history, tool evidence, local paths, and sometimes redacted or partially redacted project context. Users need to know which provider receives that payload, what it costs, and how fallback works.
+
+## Current Behavior
+
+Owned-agent continuation performs continuity checks before the user's next message is appended.
+
+1. The continuation prompt is validated. If the run is still starting or the lifecycle has queued environment messages, Xero queues the user message instead of driving a provider turn immediately.
+2. Xero creates a provider adapter from the current provider profile and model.
+3. If the request carries an enabled auto-compact preference and no active compaction exists for the session, Xero estimates the next turn size. When the configured threshold is reached, it asks the active run provider to summarize covered history and stores one active compaction record for the session.
+4. Xero reloads the run and evaluates handoff policy using project or session context-policy settings. Defaults are auto-compact enabled, auto-handoff enabled, compact at 75 percent pressure, handoff at 90 percent pressure, and keep 8 raw-tail messages.
+5. If the handoff policy blocks because pressure requires handoff but auto-handoff is disabled, continuation fails with a user-visible error.
+6. If the handoff policy decides to hand off, Xero creates or reuses a same-type target run, seeds it with a durable handoff bundle, marks the source run handed off, and returns the target run for driving.
+7. If no handoff occurs, Xero performs a hard budget check. Known over-budget continuations fail with a user-visible context-budget error. Unknown-budget continuations are allowed.
+8. Pending operator actions can then be answered, interrupted tool calls are marked, the user's continuation message is appended, and the run resumes.
+
+The continuation path has two policy layers. The auto-compact request preference can run compaction before handoff. The context-policy evaluator can also return compact or recompact decisions, but the current continuation flow only acts on blocked and handoff decisions from that evaluator. That means recompact is represented in policy and manifests but is not executed by the continuation preflight today.
+
+## Compaction Path
+
+Compaction builds a transcript source from non-system messages across the selected session or run scope. It excludes a raw tail by counting recent messages, then asks the active provider/model for a concise factual summary. The stored record includes coverage ranges, covered run ids, input token estimate, summary token estimate, raw-tail count, policy reason, trigger kind, provider id, model id, and a source hash. Inserting a compaction supersedes any previous active compaction for the same session.
+
+Replay only uses an active compaction when it covers the current run and was created by the same provider/model. Before replay, Xero recomputes the covered-source hash. If the covered transcript changed, replay fails and asks the user to refresh context and compact again. If replay succeeds, the provider receives a synthetic user message containing the compaction summary, then raw uncovered messages are replayed normally. Tool outputs are repaired when possible so provider state remains coherent.
+
+Important edge cases:
+
+- Known budget: pressure is computed from estimated next-turn tokens and the model's effective input budget, which reserves output tokens and a safety margin.
+- Unknown budget: auto-compact is skipped, handoff policy continues, and hard blocking is skipped because no limit is known.
+- Active compaction present: request-level auto-compaction does nothing. Replay later validates provider/model and source hash.
+- Active compaction stale: source-hash validation fails during provider-message reconstruction. The broader policy may say "continue" because it currently treats any active compaction as current.
+- Compaction provider failure: empty summaries, secret-bearing summaries, tool-call requests, transport failures, and provider rejections surface as retryable or user-fixable compaction errors. The continuation is not appended before those errors.
+- Provider mismatch: manual/auto compaction and replay both require the current provider/model to match the run or compaction record.
+- Provider capability: current policy inputs assume provider compaction support instead of deriving it from model capabilities.
+
+## Handoff Path
+
+Handoff builds a same-type target run rather than changing agent type. The handoff bundle includes the original goal, pending continuation prompt, source status, recent assistant summaries, active todo items, event-derived decisions/risks/questions, recent file changes, tool evidence, verification events, source-cited continuity records, approved memory and project-record retrieval results, a bounded raw-tail preview, active compaction metadata, and runtime-agent-specific fields.
+
+The bundle is stored in handoff lineage and as a high-importance project record. The target run is seeded with a developer message containing the redacted bundle and then receives the pending user prompt. The source run is marked handed off, and memory-candidate extraction is attempted for the source run.
+
+If context pressure reaches the handoff threshold and auto-handoff is disabled, continuation is blocked with a user-visible handoff error before the prompt is appended. Handoff also requires the current provider/model to match the source run provider/model, because the target run is created with that same provider identity.
+
+Run continuation after handoff works through the target run returned by the handoff preparation result. A direct continuation against the old source run is not explicitly rejected by status alone today; it can re-enter the normal continuation gates. The source-context hash gives idempotency for identical prompts, but a future implementation should hard-route source-run continuations to the target or block them with a clear message.
+
+## Preservation Audit
+
+| Context surface | Compaction | Handoff | Current risk |
+| --- | --- | --- | --- |
+| User goal and pending task | Provider summary plus raw tail | Explicit fields for goal and pending work | Summary can omit nuance unless evaluated |
+| Current task status | Summary and replayed messages | Source status plus runtime-specific section | Source status may say handed off/completed while target still has pending work |
+| Tool and command evidence | Prompt asks provider to preserve it; raw tail may include recent tools | Recent tool calls with state, inputs, and errors | Older evidence depends on summary quality |
+| Changed files | Usually summary only unless in raw tail | Recent file changes with hashes and paths | No full diff is carried |
+| Pending approvals/actions | Prompt asks provider to preserve unresolved actions | Pending prompt and tool evidence are carried | Action request table state is not serialized as a first-class bundle field |
+| Mailbox and coordination | Provider-visible context manifest can include active coordination | Not first-class in the handoff bundle except through retrieval/events | Temporary coordination can expire or be missed |
+| Stage/progress state | System prompt and events may include stage state | Active todos and event summaries may include it | Stage id/current gate is not a dedicated handoff field |
+| Memory candidates | Not extracted by compaction | Extraction is attempted when source is marked handed off | Candidate extraction depends on provider availability |
+| Verification state | Prompt asks provider to preserve it | Verification events are included | Older verification can be summarized too weakly |
+| Context manifests | Compaction artifact manifests are recorded | Target manifests include handoff identifiers and context policy | Existing evals are mostly synthetic |
+
+## Cost And Latency
+
+Token estimation is a simple character-count heuristic, roughly one token per four characters. The hard budget uses the model's effective input budget: context window minus output reserve minus a 15 percent safety reserve. For example, a 272,000-token model with a 4,096-token output reserve has an effective input budget of about 232,819 tokens.
+
+Current compaction cost is one extra provider call using the active run provider/model. Input size is the rendered covered transcript. Output is capped by prompt intent and recorded as a summary token estimate, with the request carrying a 1,500-token summary target. Replay savings are approximately covered-transcript tokens minus summary tokens, minus the retained raw tail. With the default raw-tail count of 8, savings should be large for long sessions, but latency and cost are paid on the active model, which may be the most expensive or slowest model in the user's setup.
+
+## Active-Provider Dependency
+
+Using the active run provider has a good privacy property: compaction does not introduce a new recipient for conversation history. It also preserves provider-specific formatting and reduces settings complexity.
+
+The failure modes are substantial:
+
+- Small-context active models may be unable to read the transcript that needs summarizing.
+- Slow or expensive active models make compaction feel punitive right when the user is trying to continue.
+- Unavailable active providers block both continuation compaction and handoff preparation.
+- Some models are poor summarizers or return tool calls even when no tools are exposed.
+- Provider/model mismatch rules prevent using a better summarizer even when a compatible profile exists.
+- Active-provider use makes cost display harder because compaction spend is coupled to the run model rather than an explicit continuity model.
+
+## Design Comparison
+
+| Design | Shape | Benefits | Risks |
+| --- | --- | --- | --- |
+| Active-provider compaction | Keep current behavior | Simple, no extra provider disclosure, preserves current behavior | Slow/expensive/small/unavailable active models block continuity |
+| Dedicated compaction and handoff provider | Add explicit continuity provider/profile fields | Clear cost and provider ownership, easy to reason about | Too rigid; hidden defaults would create privacy surprises |
+| Routing policy with override | Pick a configured or recommended fast large-context model, allow user override, fall back by policy | Best balance of reliability, cost, and user control | Requires model capability metadata, fallback diagnostics, and new eval coverage |
+
+Use the routing-policy design. Store configuration in app-data-backed settings, not repo-local state. The first version should support global default plus per-project override. Per-session override can come later when users need different privacy or cost behavior inside the same project.
+
+## Payload Shape
+
+Do not send only raw transcript forever. The continuity model should receive a structured bundle with:
+
+- Redacted transcript excerpts and bounded raw tail.
+- Context manifest summaries, not full manifest JSON by default.
+- Source-cited file changes, tool outcomes, pending actions, verification events, todos, and handoff lineage.
+- Existing active compaction metadata when present.
+- A strict output schema for summary, pending work, evidence, risks, and omissions.
+
+Raw transcript can remain an opt-in fallback when structured extraction is incomplete. This improves privacy, cost, and auditability because the model sees the fields Xero intends to preserve rather than every historical byte.
+
+## Settings And Fallback
+
+Add a continuity model setting with:
+
+- Scope: global app-data default and per-project app-data override.
+- Selector: provider profile plus model id, filtered to text-capable models with a known or high-confidence context window.
+- Capability labels: context window, estimated input budget, expected cost class, and privacy boundary.
+- Fallback modes: active provider, retry same continuity provider, or fail closed.
+- Disclosure: show that compaction/handoff may send conversation history, tool evidence, file paths, and redacted durable context to the selected provider.
+- Cost display: record compaction input tokens, summary tokens, provider/model, and reported cost when the provider supplies it.
+
+Default rollout should preserve current active-provider behavior unless the user explicitly configures a continuity model or joins an experiment.
+
+## Success Metrics
+
+Track these before changing defaults:
+
+- Handoff context carryover rate for goal, pending work, file changes, tool evidence, and verification.
+- Hallucinated completed-work rate in summaries and handoff bundles.
+- Pending-work preservation rate.
+- Token savings: covered transcript tokens versus replayed summary plus raw tail.
+- Continuation latency added by compaction and handoff preparation.
+- Provider failure recovery rate and user-visible retry quality.
+- User trust signals: clear provider disclosure, understandable cost, and low surprise in target-run first turns.
+
+## Test And Eval Plan
+
+Add focused coverage before shipping routing:
+
+1. Unit tests for continuity-model settings validation, app-data persistence, and fallback policy.
+2. Provider-adapter tests that force compaction failure, tool-call responses, empty summaries, provider mismatch, and source-hash mismatch.
+3. Continuation tests for known budget, unknown budget, stale active compaction, auto-handoff disabled, and source-run continuation after handoff.
+4. Structured-output evals comparing active-provider, dedicated-provider, and routed-provider summaries against the same transcript.
+5. Handoff target first-turn tests that assert pending work, verification evidence, active todos, and source citations are present before the provider call.
+6. Cost/latency instrumentation tests that verify compaction token counts and provider/model metadata are recorded.
+
+## Staged Rollout
+
+1. Instrument current behavior. Record compaction latency, input tokens, summary tokens, provider/model, replay savings, failure codes, and handoff target first-turn quality.
+2. Add the app-data continuity-model setting behind an opt-in flag. Keep active-provider fallback as the default.
+3. Add structured compaction input and schema-checked output while preserving the raw-transcript path as fallback.
+4. Run side-by-side evals for active provider, explicit continuity provider, and automatic routing.
+5. Enable user-configured continuity model routing for opted-in projects.
+6. Promote automatic routing only when evals beat active-provider compaction on carryover, hallucination, latency, and failure recovery.
+
+## Implementation Notes
+
+The change should touch the session-context contracts, provider model catalog and context-limit metadata, runtime controls/settings, session-history compaction, provider adapters, context manifests, handoff lineage and bundle creation, and the handoff-context quality eval suite.
+
+Keep new state in OS app-data/global app-data. Do not add repo-local state under legacy project directories. Because this is new behavior, do not add backwards-compatible migration glue unless compatibility is explicitly requested.

+# Solana Workbench Tool Coverage Audit
+
+## Reader And Action
+
+Reader: an engineer landing cold on the Solana workbench.
+
+Post-read action: decide whether a Solana workbench action or autonomous Solana tool is wired, covered by tests, and safe to extend without re-auditing the whole surface.
+
+## Scope
+
+This audit covers the current Solana workbench surface from three angles:
+
+- Human UI: sidebar tabs, panels, and hook actions.
+- Desktop backend: Tauri command names and Rust Solana command modules.
+- Agent surface: autonomous Solana tools, domain tool-pack discovery, request DTO names, policy expansion, and runtime executor routing.
+
+It does not require opening the app in a browser. Verification should use Tauri/Rust tests, React component tests, and mocked localnet/devnet-safe fixtures.
+
+## Human Workbench Inventory

+| RPC | Endpoint health display | refreshRpcHealth | solana_rpc_health | Sidebar smoke coverage; Rust RPC failover tests |
+
+## Autonomous Tool Inventory
+
+The Solana domain tool pack exposes exactly these autonomous tools:
+
+`solana_cluster`, `solana_logs`, `solana_tx`, `solana_simulate`, `solana_explain`, `solana_alt`, `solana_idl`, `solana_codama`, `solana_pda`, `solana_program`, `solana_deploy`, `solana_upgrade_check`, `solana_squads`, `solana_verified_build`, `solana_audit_static`, `solana_audit_external`, `solana_audit_fuzz`, `solana_audit_coverage`, `solana_replay`, `solana_indexer`, `solana_secrets`, `solana_cluster_drift`, `solana_cost`, and `solana_docs`.
+
+The current contract test verifies four invariants for that list:
+
+- Every expected tool appears in the deferred autonomous tool catalog as a Solana entry.
+- The Solana domain tool pack contains exactly the same set.
+- A custom agent policy that explicitly allows the Solana pack expands to allow each tool for the engineering runtime agent.
+- Representative request DTO variants report the expected tool names.
+
+This closes the high-risk discovery and policy-regression gap. It does not yet prove every tool can successfully execute representative happy-path inputs through the autonomous runtime.
+
+## Safety And State Findings
+
+- Solana state should live under the OS app-data namespace used by the desktop app, not under repo-local `.xero` state and not under a loose `xero` sibling directory.
+- Snapshot and persona default roots now share the same app-data namespace as the main Solana state object.
+- Mainnet persona creation/import remains policy-denied.
+- Deploy gates and secret scans have Rust tests for committed mainnet keypair hazards.
+- The current UI text keeps per-run gating language out of Solana-specific user-facing labels; the workbench does not introduce legacy workflow terminology for per-run stages.
+
+## Issue 45 Coverage Additions
+
+- Autonomous runtime fixture tests execute each of the 24 Solana tools with representative safe input and assert the stable Solana output envelope.
+- Negative autonomous runtime tests cover mutation-adjacent send, IDL publish, deploy, rollback, and verified-build calls with policy-aware, non-leaky errors.
+- Focused panel component tests cover persona creation, scenario launch, transaction simulation/priority-fee parsing, and safety scans through user-facing controls.
+- Agent-visible Solana tool results now redact keypair paths, RPC tokens, wallet/provider credential fields, screenshot-like payloads, exported diagnostic raw payloads, and telemetry-like payloads before returning to the runtime caller.
+
+## Verification Commands
+
+Use scoped commands. Do not run broad repo-wide Rust tests for this audit unless storage and time budgets are explicitly available.

+# Web Search Functionality Audit
+
+Issue: <https://github.com/hyperpush-org/xero/issues/37>
+
+Date: 2026-05-31
+
+## Status
+
+Implemented.
+
+`web_fetch` remains an independent direct HTTP/HTTPS text fetch and works without any search-provider configuration. `web_search` is now configured from OS app-data-backed Settings, not process environment variables. The default mode is `Auto`: provider-managed LLM search is attempted first when the active provider/model can support it, then Xero falls back to the user's active configured web-search provider profile. Users can also force `Provider-managed only`, force `Configured provider only`, or disable `web_search`.
+
+Configured provider API keys are stored through the global `provider_credentials` path under web-search-scoped credential ids and are filtered out of the normal LLM provider credential UI. Settings rows expose only readiness metadata such as `hasApiKey`, `apiKeyUpdatedAt`, and last-check status.
+
+## Current Surfaces
+
+Runtime tools live in `client/src-tauri/src/runtime/autonomous_web_runtime/`:
+
+- `mod.rs` defines `web_search`, `web_fetch`, request/output DTOs, limits, Settings-backed configured-provider config, provider-managed config, and search mode.
+- `managed.rs` constructs bounded provider-managed search requests for Anthropic, OpenAI Responses, Gemini grounding, xAI Responses, and OpenRouter server web search, then normalizes cited URLs into the same agent-visible result shape.
+- `search.rs` validates queries, applies source precedence, calls configured provider adapters, normalizes common provider JSON result shapes, rejects invalid or oversized payloads, normalizes HTTP/HTTPS result URLs, decodes HTML entities, and caps result counts/snippets.
+- `fetch.rs` validates absolute HTTP/HTTPS URLs, fetches text/html, application/xhtml+xml, or text/plain, extracts readable HTML text/title, and enforces character/byte limits.
+- `transport.rs` uses blocking reqwest with timeouts, redirect limits, GET/POST support, auth headers, redacted transport errors, and response-size caps.
+
+Agent exposure is wired through these paths:
+
+- Tool descriptors: `client/src-tauri/src/runtime/agent_core/tool_descriptors.rs` exposes `web_search` and `web_fetch` schemas.
+- Tool discovery/catalog: `client/src-tauri/src/runtime/autonomous_tool_runtime/mod.rs` exposes web catalog entries and the `web_search_only`, `web_fetch`, and `web` tool-access groups.
+- Planner activation: prompts mentioning docs, documentation, internet, latest, current, web search, or web fetch activate search/fetch without browser-control tools.
+- Dispatch: `client/src-tauri/src/runtime/autonomous_tool_runtime/mod.rs` maps `AutonomousToolRequest::WebSearch` and `AutonomousToolRequest::WebFetch` to runtime execution.
+- Model-visible results: `client/src-tauri/src/runtime/agent_core/provider_loop.rs` compacts web output and marks web content as untrusted lower-priority data.
+- Stream summaries: `client/src-tauri/src/commands/subscribe_runtime_stream.rs` maps web calls into `ToolResultSummaryDto::Web`.
+
+Permissions and policy:
+
+- `web_search` and `web_fetch` are `external_service` tools with network risk metadata.
+- Computer Use can use external-service tools. Plan and Crawl policies do not expose them.
+- Custom agents need an effective policy/base capability that allows `external_service`.
+- Project capability revocation can block external integrations via `external_integration:external_service` or the exact tool name.
+- Stage gates still apply at runtime through the normal tool enforcement path.
+
+UI and operator affordances:
+
+- Tool categories include a `Web` category for agent authoring and runtime presentation.
+- Tool call summaries render as web summaries in transcript/runtime streams.
+- Settings includes a first-party `Web Search` section that lets users choose mode, inspect provider-managed readiness, add/edit/delete/enable/test/select configured providers, and save provider API keys without returning secrets after save.
+- Tauri commands are exposed through the desktop adapter for loading/updating settings, upserting/deleting/selecting configured providers, and checking providers through the same runtime adapter path agents use.
+- Doctor diagnostics report mode/source readiness, provider-managed status, active configured-provider readiness, and last-check status without exposing secrets.
+- The README documents Settings-only configuration and the custom endpoint contract. Environment variables no longer configure or override web search.
+
+## Verified Behavior
+
+Focused Rust tests cover:
+
+- Settings defaults, validation, credential-backed readiness, Google CSE `cx` requirements, and custom endpoint requirements.
+- Search calls configured providers, normalizes returned titles/snippets/URLs, marks provider-overflow results as truncated, and includes source labels.
+- Search without a configured source returns a clear user-fixable unavailable error.
+- All planned configured provider kinds construct requests successfully against mock transport: `custom_endpoint`, `brave_search`, `tavily_search`, `exa_search`, `firecrawl_search`, `you_search`, `linkup_search`, `kagi_search`, `searxng_json`, `serpapi_google`, `searchapi_google`, and `google_cse`.
+- `Auto` falls back from a retryably failed provider-managed request to the configured provider.
+- Timeout, retryable status, malformed provider payload, oversized payload, and unsupported fetch payload paths fail closed.
+- Fetch works without a search provider, extracts HTML title/text, normalizes content type, and uses the direct HTTP transport.
+- Tool-search catalog fields now match the real schemas: `resultCount` and `maxChars`, not stale `limit` and `maxBytes` names.
+- Frontend TypeScript, lint, and focused Settings Dialog tests cover the Web Search section load/render path, mode selection dispatch, and configured-provider test dispatch.
+
+## Gaps
+
+No known implementation gaps from this audit remain. The explicit non-goals below remain out of scope: unofficial scraping of consumer search-result pages, retired Bing Search API support, and first-class Serper support until its current official API contract is verified.
+
+Live account/provider behavior can still vary by plan, model, admin toggle, region, and provider rollout. Xero handles those as runtime readiness/check failures and keeps the configured-provider fallback available according to mode.
+
+## Implementation Plan
+
+Target outcome: an end user can enable web search from Settings, and agents can use `web_search` without any process environment variables. If the active LLM provider/model has LLM-provider-managed web search enabled and supported, Xero should use that first. If provider-managed search is unavailable or insufficient, Xero should fall back to the user's active in-app web-search provider profile. Users can add a fallback provider in Settings, save its API key with the same storage/redaction guarantees used for LLM provider keys, test it, and choose it as the active fallback provider.
+
+Search-source precedence:
+
+1. `disabled`: if the user or policy disables web search, agents do not search.
+2. `provider_managed`: if enabled, supported by the active LLM provider/model, and allowed by policy/stage gates, use the LLM provider's own web-search path first. This includes true native model-provider tools and provider-managed server tools such as OpenRouter's web-search tool.
+3. `configured_provider`: if provider-managed search is disabled, unsupported, unavailable for the user's account/plan, rate-limited, returns no usable cited sources/URLs, or fails with a retryable provider error, use the active in-app web-search provider profile.
+4. `unavailable`: if neither source is ready, agents get a clear unavailable state and may only use `web_fetch` for exact HTTP/HTTPS URLs already known from the user or other context.
+
+Settings should expose this as a web-search mode with `Auto` as the default: LLM-provider-managed search first, active configured provider second. Additional modes should be `Provider-managed only`, `Configured provider only`, and `Disabled`. The runtime should avoid running both search sources by default because that can double-bill users and produce confusing duplicate evidence.
+
+LLM-provider-managed search candidates checked against current provider docs on 2026-05-31:
+
+| Managed search source | Xero provider ids | Notes |
+| --- | --- | --- |
+| `anthropic_native_web_search` | `anthropic`; `vertex` for Anthropic-on-Vertex only when the selected model/API supports it | Anthropic exposes web search as a server tool for Claude. Direct Anthropic should be the first target. Anthropic-on-Bedrock should not be assumed because Anthropic documents Bedrock as unsupported for this tool; Vertex support must be capability-gated because support level varies by platform/model. |
+| `openai_native_web_search` | `openai_api`; `azure_openai` and `openai_compatible` only after capability probing | OpenAI exposes web search through the Responses API and search-capable Chat Completions models. Xero should prefer the Responses tool path where the adapter already uses Responses-style requests. |
+| `gemini_grounding_google_search` | `gemini_ai_studio`; future Vertex-Gemini providers if added separately | Gemini exposes Google Search grounding through a model tool and returns grounding metadata. Use only for Gemini models whose API docs/capability probe report grounding support. |
+| `xai_native_web_search` | `xai` | xAI exposes web search as a Responses API tool. Use it when the selected Grok model supports the text runtime and native web search capability. |
+| `openrouter_server_web_search` | `openrouter` | OpenRouter exposes a beta server-side web search tool. Treat it as LLM-provider-managed search for Xero's precedence rules, but do not describe it as always native to the underlying model. Its engine behavior should be recorded in diagnostics so users can see whether OpenRouter used a native provider path or an OpenRouter-selected engine such as Exa, Parallel, or Firecrawl. |
+| `perplexity_native_web_grounding` | OpenRouter-routed Perplexity models today; future direct Perplexity provider only if Xero adds one | Perplexity-style models are search-grounded LLM providers rather than normalized SERP APIs. Do not add this as a direct source until Xero has a first-class Perplexity provider or a capability-probed OpenAI-compatible profile that returns cited source URLs. |
+
+LLM-provider-managed search must still use in-app configuration only. It inherits the active LLM provider credential and model settings; it must not introduce web-search environment variables or a second copy of the LLM API key. Native or provider-managed search citations/results should be normalized into the same agent-visible search evidence shape used by configured providers, tagged with a source such as `provider_managed:<provider_id>`, and treated as untrusted web content.

+Planned provider adapter set:
+
+| Provider kind | Type | Auth/storage | Notes |
+| --- | --- | --- | --- |
+| `custom_endpoint` | Normalized endpoint | Optional bearer API key in provider credentials | Preserves the current Xero contract: `GET <endpoint>?q=<query>&limit=<count>` returning `{ "results": [{ "title", "url", "snippet" }] }`. |
+| `brave_search` | Direct web index | API key in provider credentials, sent as Brave's subscription-token header | General web results from Brave Search. Initial adapter should normalize organic web results only; images/news/suggest can be later feature flags. |
+| `tavily_search` | Agent/RAG search API | API key in provider credentials, sent as bearer auth | Good default for agents that need LLM-oriented snippets, domain filters, freshness, and optional raw content. Initial adapter should request result snippets only, not Tavily-generated answers. |
+| `exa_search` | Neural/keyword web search API | API key in provider credentials, sent as Exa API-key header | Good for semantic discovery and source finding. Initial adapter should expose search type and optional highlights, while keeping result output normalized. |
+| `firecrawl_search` | Search plus optional scrape | API key in provider credentials, sent as bearer auth | Useful when the user wants search results and optional page markdown. Initial adapter should default to URL/title/description only; scrape options should be explicit because they increase latency/cost. |
+| `you_search` | Web/news search API | API key in provider credentials, sent as You.com API-key header | Good for AI-oriented web/news results. Initial adapter should normalize web results first and optionally include news when the query asks for news/current events. |
+| `linkup_search` | AI-oriented web search API | API key in provider credentials, sent as bearer auth | Good for source-grounded search with shallow/deep modes. Initial adapter should use search-results output, not synthesized answer output. |
+| `kagi_search` | Premium search API | API key in provider credentials, sent using Kagi API auth | Good for users who already pay for Kagi and want personal/premium search results. Settings should note account/API availability requirements. |
+| `searxng_json` | Self-hosted or trusted metasearch | No key by default; optional bearer/basic credential if an instance requires it | Lets users point Xero at their own SearXNG `/search?format=json` instance. Settings must warn that many public instances disable JSON output or rate-limit automation. |
+| `serpapi_google` | Google SERP compatibility API | API key in provider credentials, sent as SerpApi requires | Useful for Google-like SERP fields, location, and verticals. Initial adapter should normalize organic results and avoid returning ads/knowledge panels as ordinary sources. |
+| `searchapi_google` | Google SERP compatibility API | API key in provider credentials | Similar Google SERP compatibility path. Initial adapter should normalize organic results and preserve provider diagnostics for rate-limit/parameter errors. |
+| `google_cse` | Google Programmable Search / Custom Search JSON API | API key in provider credentials plus user-provided `cx` in provider settings | Compatibility adapter for users with an existing Programmable Search Engine. It should not be the default recommendation because setup requires a configured search engine id. |
+
+Backlog / explicit non-goals:
+
+- `serper_google` should be treated as a candidate adapter only after implementation work verifies current official API documentation, response schema, auth, and terms. Users can still use Serper through `custom_endpoint` or a small proxy if they need it before a first-class adapter exists.
+- Legacy `bing_web_search` is not planned as a direct adapter because Microsoft retired the Bing Search APIs on August 11, 2025. Microsoft's Grounding with Bing Search is an Azure AI Agents/Foundry feature, not a direct normalized SERP API; evaluate it separately if Xero adds Azure-agent-specific integrations later.
+- Unofficial scraping of consumer search-result pages is out of scope. Built-in providers must use documented APIs or user-owned/self-hosted endpoints.
+
+1. Add app-data-backed autonomous web settings and provider profiles.
+   - Add global OS app-data state for web search, not repo-local `.xero/` state. Store non-secret settings such as search mode, provider-managed enablement, active fallback provider id, fallback provider kind, display name, enabled state, endpoint/base URL where applicable, result-limit defaults, last-check status, and update timestamps.
+   - Support multiple fallback provider profiles with exactly one active enabled fallback profile. A disabled fallback profile can remain saved, but it must not be selected for runtime fallback search.
+   - Add provider-managed search capability metadata for LLM provider/model pairs. The metadata must distinguish documented support, unsupported providers/models, user/account enablement requirements, and "unknown, probe before use" states.
+   - Include all provider kinds in the planned provider adapter set above. Each adapter owns request construction, auth header/query placement, response decoding, provider-specific errors, and normalization into `AutonomousWebSearchResult`.
+   - Store provider-specific non-secret settings: search region/language where supported, freshness defaults where supported, result limit, safe-search preference where supported, and provider-specific fields such as Google CSE `cx` or SearXNG instance URL.
+   - Remove env-backed search-provider configuration from runtime resolution. `DesktopState::autonomous_web_config` should resolve from saved app-data Settings only; if there is no active ready provider, the runtime has no configured search provider.
+   - Environment variables must not enable, override, or bypass in-app Web Search settings. Diagnostics should report the active source as `settings` or `unconfigured`.
+
+2. Store API keys like LLM provider keys.
+   - Reuse the global `provider_credentials` pattern for web-search API keys instead of introducing a parallel secret store. Extend the credential provider catalog/validation so web-search provider ids are accepted without making them LLM runtime providers.
+   - Store secrets only in credential rows/fields intended for provider secrets. Web-search settings rows must reference credential/provider ids and expose only readiness fields such as `hasApiKey`, `updatedAt`, and readiness proof.
+   - Tauri commands and DTOs must never return raw API keys after save, matching LLM provider credential behavior.
+   - Redaction must cover web-search provider ids, endpoint URLs, auth headers, query parameters, support bundles, diagnostics, development storage views, runtime stream summaries, logs, and failed provider-check payloads. Tokens must not appear in model-visible tool output.
+   - Deleting a web-search provider profile must either delete its linked credential or clearly detach it according to the same UX rules used for LLM provider credentials.
+
+3. Add Tauri commands and model contracts.
+   - Add commands such as `autonomous_web_search_settings`, `autonomous_web_search_upsert_provider`, `autonomous_web_search_delete_provider`, `autonomous_web_search_set_active_provider`, and `autonomous_web_search_check_provider`.
+   - Validate provider kind, HTTP/HTTPS endpoints, result limits, timeout limits, credential readiness, enabled/active invariants, and provider-specific required fields.
+   - Expose configured-provider capability metadata to the UI: whether the fallback provider supports freshness, domains, locale/region, news, content extraction, safe search, self-hosting, or answer synthesis. The agent-facing `web_search` schema should stay provider-neutral unless a later design adds explicit advanced options.
+   - Expose provider-managed search capability metadata to the UI and runtime: provider id, model id, native tool type/name where applicable, source/citation format, known unsupported deployment paths, and whether an account/admin toggle may be required.
+   - The fallback provider check must use the same runtime adapter and transport path agents use, with a harmless query and bounded response. It should return a redacted status, normalized sample result count, latency, and actionable error code.
+   - Add a provider-managed search readiness check where feasible. It should be bounded and redacted, should not leak prompts or API keys, and should classify failures such as unsupported model, admin/account disabled, rate-limited, unavailable, no cited sources, or provider returned answer-only output.
+   - Keep `web_fetch` independent of search-provider settings.
+
+4. Add a Settings UI.
+   - Add a user-facing Web Search section in the existing agent/tooling settings area using ShadCN components only.
+   - Let users choose the web-search mode: `Auto`, `Provider-managed only`, `Configured provider only`, or `Disabled`.
+   - Show provider-managed search availability for the selected LLM provider/model when known, including unsupported/unknown/account-toggle-required states. The UI should explain fallback status through concise labels, not raw provider errors.
+   - Let users add, edit, delete, enable/disable, test, and select the active fallback web-search provider. Show provider kind, endpoint/base URL when relevant, masked credential state, readiness, and last check result.
+   - Saving a fallback provider with an API key should behave like LLM provider key entry: accept the secret once, persist it through the provider credential path, and then show only masked/readiness state.
+   - Do not add temporary debug UI.
+
+5. Wire agents to configured provider availability.
+   - Keep `web_search` as the logical agent tool. Runtime dispatch chooses the actual source from the search-source precedence above.
+   - In `Auto`, use provider-managed search first when the active LLM provider/model supports it and the user has not disabled it. Fall back to the active configured provider when provider-managed search is unsupported, unavailable, account-disabled, rate-limited, retryably failed, or did not produce usable cited source URLs.
+   - In `Provider-managed only`, do not fall back to configured providers. If provider-managed search cannot run, return a clear unavailable state.
+   - In `Configured provider only`, skip provider-managed LLM search and use the active fallback provider profile.
+   - When neither source is ready, agents must receive a clear unavailable state. They should not retry blind searches or imply current web access. They may still use `web_fetch` for exact HTTP/HTTPS URLs supplied by the user or found elsewhere.
+   - Tool access/catalog diagnostics should show whether `web_search` is ready through provider-managed search, ready through fallback provider, disabled, unsupported for the selected model, missing credentials, account-disabled, or unconfigured.
+   - Stage gates, external-service policy checks, project capability revocations, and model-visible untrusted-content boundaries continue to apply exactly as they do today.
+
+6. Tighten diagnostics and docs.
+   - Add doctor/support-bundle output that reports web-search mode, selected runtime source, native provider/model capability status, active fallback provider kind, readiness, fallback reason, and last check status without exposing tokens or raw auth-bearing URLs.
+   - Document the custom endpoint contract, named-provider setup flow, provider-managed LLM search behavior, fallback precedence, auth handling, result limits, status-code handling, body limits, and failure modes.
+   - Update README to remove env-var web-search setup and document the Settings-only configuration path.
+
+7. Expand tests.
+   - Rust unit tests for settings validation, provider-profile CRUD, active-provider invariants, credential resolution, config resolution, provider check, search/fetch success, missing provider, disabled provider, missing key, invalid provider response, non-2xx status mapping, truncation, and redaction.
+   - Provider-adapter tests for every provider kind in the planned adapter set, using local mock servers and no live network dependencies.
+   - Contract fixture tests for provider response normalization: Brave, Tavily, Exa, Firecrawl, You.com, Linkup, Kagi, SearXNG JSON, SerpApi, SearchAPI.io, Google CSE, and `custom_endpoint`.
+   - Native-search adapter tests for Anthropic, OpenAI, Gemini, xAI, and OpenRouter request construction, response/citation normalization, unsupported model handling, account-disabled handling, rate-limit handling, and no-usable-source fallback.
+   - Frontend schema and Settings UI tests for mode selection, native availability display, add/edit/delete/enable/disable/select-active/save-key/load/test-provider flows.
+   - Runtime/tool-access tests proving agents prefer provider-managed search in `Auto`, fall back to configured providers when provider-managed search is unavailable or insufficient, honor `Provider-managed only` and `Configured provider only`, avoid double-searching by default, and return a clear unavailable state when no configured source can run.
+   - Config-resolution tests proving `XERO_AUTONOMOUS_WEB_SEARCH_URL` and `XERO_AUTONOMOUS_WEB_SEARCH_BEARER_TOKEN` do not configure or override web search.
+   - Runtime stream, diagnostics, development-storage, and support-bundle tests proving API keys and bearer tokens are redacted.
+   - A scoped integration test with a local mock search provider to prove the same Tauri runtime path works end-to-end.
