Re-home agents to a new API base URL through the agent/config response (backend move or per-tenant EU->US region move) - the lesson from the 2026-07-18 WEU->GWC cutover, where the compiled-in API hostname hard-cut every in-flight agent (no DNS indirection possible: mTLS breaks behind a proxy, Flex custom-domain TLS is broken). Backend (ConfigVersion 33): - AdminConfiguration.AgentMigrateApiBaseUrl (global) + AgentMigrateTenantOverridesJson (tenantId->URL; empty value pins a tenant against the global target; override wins) - GetAgentConfigFunction.ResolveMigrateTarget serves the validated target; AgentMigrateServed / AgentMigrateRejected warnings as delivery evidence - TableConfigRepository Store+Map; admin portal Global Settings round-trip Agent (kill-switch-mirrored hardening): - Shared AgentEndpointMigrationRules: https-only, *.azurewebsites.net on a label boundary, no path/port/userinfo - enforced on BOTH sides - Live fetch only: RemoteConfigService cache strips the field on write AND read; EndpointMigration.ResolveTarget re-checks the fetch outcome - AgentRuntimeConfig.Resolve returns before merge/integrity/bootstrap cleanup on a pending migration (no spurious IntegrityCheckFailed against a stale migration stub), Program.RunAgent rebuilds Phase 3+4 against the new URL - single hop, kill signal wins before and after the hop Tests: AgentEndpointMigrationTests (backend rules + resolution), EndpointMigrationTests + cache-hardening strip (agent). Full suites green (Functions 2992, Agent Core 1822, vitest 557, tsc silent). Doc: docs/agent/endpoint-migration.md Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

- Creation: Added
agent/endpoint-migration.md— config-channel agent re-home (MigrateToApiBaseUrlonGET agent/config, ConfigVersion 33): backend or per-tenant API-URL moves without DNS indirection (impossible due to mTLS/Flex-TLS). Live-fetch-only with cache strip,AgentEndpointMigrationRulesallowlist validated on both sides, one hop, kill-switch wins. Built as the lesson from the 2026-07-18 WEU→GWC cutover, which hard-cut all in-flight agents.

- Creation: Added
agent/build-counter-blob.md— agent build numbers now come from a shared public counter blob (buildcounter-v{N}.txt, reserve-before-build with ETag-CAS) so localbuild.ps1and CIbuild-agent.ymlbuilds can never mint the same number. Documents the CI parity fixes (SummaryDialog.exe.config in the ZIP, EXE-vs-manifest version check, hash-oracle update gated on stable cutover) and the Sigstore provenance attestation on CI-built ZIPs.

- Creation: Added
agent/autopilot-ztd-diagnostics.md— reference for Windows' own ZTD diagnostic surfaces (ModernDeployment Autopilot event IDs incl. 807/809/815/908, theDiagnostics\Autopilotregistry key, deployment-service endpoints, known-issue error-code map with KB fixes). Backs the agent'sZtdEvidencecollector (ztdVerdictonautopilot_profile_missing) and the backend known-issue rules; sources carry a re-check RSS feed.

Removal: Moved
customer-graph-add-on-permissions.mdout of this contributor bundle into the customer documentation repository (reference/optional-graph-permissions.md). It was customer-facing product content and did not belong in the tech-docs bundle; removed the entry fromindex.md. -
Creation: Added
agent/hello-wizard-unskip.md— session 772fe502 fix: theHelloWizardStarteddecision signal (prevention veto + un-skip cure for the policy-disabled Hello shortcut) and the HelloTracker confirmation second read against flip-flopping WHfB CSP values.

Creation: Added the
agent/section — three concept documents on the V2 agent:agent/overview.md(runtime, collectors, telemetry pipeline),agent/decision-engine.md(DecisionCore reducer, signals, A/B/C completion arms, invariants),agent/logs-and-persistence.md(persisted artifacts, signal log vs spool, recovery/replay flow) plusagent/index.md. -
Creation: Converted
docs/into an OKF v0.1 knowledge bundle — added YAML frontmatter toarchitecture.md,mcp-oauth-flow.md, andcustomer-graph-add-on-permissions.md; createdindex.mdand this log.
