+# Conditional scheduled tasks
+
+A scheduled task can make an action conditional: create an inventory item only
+if it is absent, commit files only if they changed, or import a record only if
+it has not already been processed. The end-of-run verifier receives bounded
+structured evidence from tool arguments and results, separately, in addition
+to call success. Previously it only saw names and success booleans, so it could
+demand an action the task's selected branch forbade.
+
+All conditions, required actions and prerequisites come from the original task.
+Fleet does not assign completion meaning to a connector's field names or values.
+A claimed condition cannot replace missing prerequisite calls or failed checks.
+For long tasks, truncation retains the opening identity and closing stop rules.
+
+The evidence projection is structural rather than an application field list:
+
+- It accepts JSON objects and the standard MCP text-content wrapper, recursively
+  retaining short identifier strings, exact numbers, booleans and nulls under
+  their original field paths. Arbitrary wrapper and field names work alike.
+- The existing shared secret scrubber runs before extraction. Credential-bearing
+  subtrees, prose, URLs and bulk arrays are omitted. No tool-result text becomes
+  a verifier instruction or an authorization grant.
+- Input is limited to 1 MiB; each projection is capped at 4 KiB, 32 fields,
+  256 visited entries and four nested object levels. Sorting makes selection
+  deterministic. Unsupported, malformed or omitted evidence remains unknown.
+
+The verifier remains a model-based check with its existing bounded invocation,
+metering and fail-open error behavior, not a deterministic proof of a business
+workflow. Task authors and external bundles own those workflow contracts.
+
+An explicit `confirm_audit(success=true, critical_actions=[])` now records
+completion without inventing a future mutation. It activates the
+typed gate with no new commitments and therefore authorizes no new critical
+calls. Existing outstanding commitments remain outstanding. Missing/null
+successful-audit declarations still fail. Explicit terminal audit aborts retain
+the failed run outcome and skip the driver reviewers instead of re-demanding
+abandoned actions.
+
+## Copyable execution prerequisites
+
+Prompt producers may include one literal line followed by one JSON object:
+
+```text
+EXECUTION REQUIREMENTS (JSON):
+{"mcp_servers":["inventory"],"required_tools":["mcp_inventory_inspect"],"network":true}
+```
+
+Fleet checks this optional declaration at **dispatch**, before model execution.
+A sealed task/global lockdown produces an actionable network error. After the
+run's MCP scope and remote overlay are opened, missing advertised servers/tools
+produce an actionable roster error. Tools may be native names, server tool names,
+or Fleet's full `mcp_<server>_<tool>` names; full names avoid ambiguity. Model
+resolution already happens before the run and remains mandatory.
+
+This declaration only restricts a run. It cannot enable network, bypass the
+broker, select credentials or override an administrator's allowlist. It does not
+prove endpoint reachability, per-account authorization or source completeness;
+the executing workflow must still check those. Unknown companion metadata is
+ignored for forward compatibility, including producer labels such as `mode`.
+Malformed/duplicate declarations fail closed. Ordinary prompts with no marker
+keep their existing behavior.
+
+## Scope
+
+This fixes conditional completion and provides early execution diagnostics for
+copy/paste handoffs. MCP catalogs, credentials, tool contracts and customer
+protocols remain in external config bundles; Fleet does not import or depend on
+a producer application. This does not edit existing tasks or add a scheduling
+UI/import API. Regenerate producer prompts to gain the prerequisite check.
+Existing recurrence, retry and sandbox permissions are unchanged.
+Provider errors remain governed by the existing typed status/SSE retry classifier;
+a generic provider-error string without status is insufficient evidence to retry
+an external mutation. Provider adapter diagnostics and customer source-grain
+migrations are separate changes, not silently bundled into this fix.
