Microsoft refresh group 4 of 5 — October 28, 2026¶
This group refreshes ten guides and maps 784 current detailed objectives. Eight guides in one group remain in the frozen 48-guide refresh after this group. Two subset exam researchers read five complete guides each; technical and learning researchers record their narrower source-body scopes. The coordinator owns shared edits.
The operations ledger records exact guide, objective and teaching-span hashes, opened URLs, research/repair scopes, source limits and historical preservation. This is bounded AI-assisted content review; a full independent rubric-2 audit, human review and product/lab execution remain separate.

Objectives, teaching and history¶
All ten current objective files and all ten status files remain byte-identical to the accepted baselines. No objective archive, effective-date change or historical pointer migration is required. Earlier source/deep/audit review objects retain their original values.
The initial matrices preserve 69 concrete workflow flags in subset A and 233 conservative leads in subset B. All 69 A flags gained actual workflow teaching. B adjudication credits 81 repairs and identifies 152 already adequate for the objective verb, with individual reasons. Those counts are not interchangeable with packet counts. Fifty-nine exam-research packets include lifecycle/assessment changes as well as teaching; four additional independent teaching repairs are recorded separately. Technical/resource edits and link repair add their own evidence.
Independent review also found a systemic binding defect: some references pointed at front matter or truncated introductory text despite valid hashes. The previous matrix is preserved; current B bindings are regenerated from explicit authored sections, missing/ambiguous sections raise errors, and front-matter fallbacks are forbidden. Hash identity is not semantic coverage. Final independent rechecks are recorded in the ledger before delivery.
DP-900¶
Retain describe-level coverage and add a source-to-store/report evidence route. Clarify explicit semantic-model creation and source-to-Power-BI type mapping; a source column does not automatically survive model synchronization.
MB-230¶
Add resolution-dialog, translated knowledge, suggested contacts, skill classification, Inbox and model-driven extension workflows. Preserve the stale metadata observation as history. Configured confirmation versus imprecise semi-autonomous send wording remains blocked; language eligibility and actual runtime behavior are separate checks.
MB-310¶
Add ledger aliases, periodic/Excel journals, cash-flow/shared-payment setup, consolidation, tax, receivable/payable/expense, budget and fixed-asset workflows. Amounts and rates are invented paper examples, not tax policy or posted results. New references distinguish Finance-integrated Project Operations and preserve history-dependent deferral limits.
MB-500¶
Add developer issue, map, X++, workflow, linked-table serializer, reporting/ER, entity/delta, vault and asynchronous/cache workflows. Independently repair inheritance/abstraction and InMemory versus TempDB treatment. Current LCS-to-admin-center migration is preview with workload, downtime and capacity limits; no compiler, migration or runtime task was executed.
MB-800¶
Add audit, costing, recurring/blanket/prepayment, fixed-asset and inventory workflows. Independently repair account-type default dimensions and main-asset/component setup. Payables Agent activation identity/mailbox and billing remain distinct. The approval-lab blank-approver inconsistency is labeled rather than copied as a valid universal chain.
MB-820¶
Add object/report/query, AL reasoning, profile/view, onboarding, testing and extension-telemetry contracts. Distinguish supported try-method argument/write behavior and v29 PowerShell7 modules. Lab02 has duplicate/self-call code and a missing expected precondition trigger; use it for critique and independent design, not a validated paste/run solution.
PL-300¶
Add explicit/quick/group calculations, calculated column/table creation, drillthrough/tooltips and Copilot page/narrative worksheets. Keep model compatibility, refresh grain and narrative refresh separate. ADBC cloud/gateway behavior is scoped. No paid lesson or engine result is claimed.
PL-900¶
Add AI-assisted app creation, document/desktop automation and topic-node workflows. Evaluations use the signed-in identity; test profiles do not impersonate users. Dataverse for Teams has future creation/suspension/decommission milestones, separate from ordinary Teams and full Dataverse apps. Replace the missing path with a specifically inspected 24-minute orientation course; no paid lesson or engine result is claimed.
SC-500¶
Add Windows AMA/WEF ingestion/table/detection paths and agent-protection evidence tasks. The removed Foundational CSPM announcement does not prove a default change or cancellation; the answered check now agrees with that limitation. Keep current preview plan-management/billing and later announced billing changes separate from exam scope.
AB-250¶
Add conversation/voice/channel, survey, scripts/macros, profile/context, knowledge and verified SDK operation contracts. Smart assist, Copilot agents and real-time voice are distinct. A timeline connector implements IRecordSource; it is not an ordinary Power Automate connector. Phone-number date/eligibility contradictions remain blocked. The public credential page advertises a Practice Assessment; launch remains sign-in-required and untested, and no questions were inspected.
Evidence and validation¶
The initial pass checked 468 source records: 445 reachable, 19 automation-blocked, three DNS failures and one HTTP404. All three partner-hub IDs passed sequential retry. The missing PL-900 path remains in catalog/history but is absent from current recommendations; the replacement public course page was inspected. All 128 main additional associations, four later Power BI associations, three voice sources and six independent-repair sources returned HTTP200. The separately checked course observation is also retained. 139 evaluated sources were registered; 40 evaluated existing entries plus two association/availability entries were updated, with exact reading scopes. Public course outlines and metadata are not paid-content or runtime evidence.
Two fresh-context read-only reviewers passed their bounded final teaching/binding/support checks after four A teaching repairs and the B matrix correction. The ledger preserves the initial findings and separate repair verifications. All 784 objective wordings and 1,126 teaching spans match their current bindings. Historical preservation checks pass for 319 source reviews, 196 deep-review receipts, 42 AI-audit batches and all 20 objective/status files. The final local gate runs 199 unit tests, repository/resource checks, a strict site build and generated-site validation; actual outcomes are recorded in the ledger before stage/commit/push. Source blockers remain visible; none is cleared merely because a URL works. No Finance/Business Central/Power BI/Contact Center/cloud/compiler/SDK workflow was executed.
